Description

Technical Field

[0001] This invention relates to the field of straightening machine technology, and more particularly to an adjustment device and a straightening machine. Background Technology

[0002] Pickled steel sheets (e.g., 1mm-6mm thick) are products made from hot-rolled steel sheets after pickling to remove iron oxide scale. They inherit the characteristics of hot-rolled steel sheets while placing higher demands on surface quality and sheet shape. The 17-roll straightener is a crucial finishing piece in the pickled steel sheet production line. It comprises a straightening roll system, including straightening rolls and support rolls. The 17-roll straightener also includes a main machine, bearings, a transmission system, and spaced-apart roll boxes and arches. The support rolls are installed within the roll boxes. It should be noted that the specific positional and connection relationships between the various structures included in the 17-roll straightener are detailed in existing technology and will not be elaborated upon here.

[0003] In actual operation, by precisely adjusting the pressure and bending amount of each row of straightening rollers, different plastic stretching can be applied to different areas along the width of the workpiece to be processed (such as pickled plates, steel plates, or metal strips). However, during long-term operation, the straightening rollers will continuously rub against the high-temperature, high-strength steel or metal strips, inevitably causing wear. At this point, the roller surface will gradually wear down, losing its original smoothness and becoming rough. This will directly leave scratches, indentations, or pits on the surface of the straightened metal material, severely affecting the product surface quality. Furthermore, uneven wear will cause dynamic imbalance when the straightening rollers rotate at high speeds, resulting in severe vibration and abnormal noise in the equipment. This not only affects product quality but also damages the main unit, bearings, and transmission system of the straightening machine. Therefore, the straightening roller system needs to be replaced regularly.

[0004] To enable rapid online replacement of straightening rollers, a functional gap (approximately 1mm-2mm) is reserved between the roller box and the arch. However, during the straightening process of pickled plates, the straightening speed reaches 2m / s-4m / s, and the enormous straightening force is transmitted to the arch through the straightening roller system and roller box. Due to the aforementioned functional gap, the roller box and arch are not an absolutely rigid whole, resulting in the roller box continuously impacting the arch during the actual straightening process of pickled plates. The impact between the roller box and the arch generates instantaneous, high-frequency impact loads that exceed the original design load. These impact loads directly damage the straightening roller system, shorten its lifespan, and consequently affect the service life of the straightening machine.

[0005] Therefore, how to extend the service life of the straightening roller system, and thus extend the service life of the straightening machine, has become a technical problem that the industry urgently needs to solve. Summary of the Invention

[0006] The purpose of this invention is to provide an adjustment device and a straightening machine for extending the service life of the straightening roller system, thereby extending the service life of the straightening machine.

[0007] To achieve the above objectives, in a first aspect, the present invention provides an adjustment device. The adjustment device is applied to a straightening machine, which includes a gate and roller boxes spaced apart. Along the height direction of the straightening machine, the roller boxes include an upper roller box and a lower roller box. The adjustment device includes: a first adjustment structure, a first power structure, a second adjustment structure, and a second power structure. The first adjustment structure is located between the gate and the upper roller box, and has opposing first and second surfaces. The first surface of the first adjustment structure faces the upper roller box, and the second surface of the first adjustment structure is fixedly connected to the gate. The first power structure is connected to the first adjustment structure and is used to switch the first adjustment structure between a first position state and a second position state. In the first position state, the first surface of the first adjustment structure is spaced apart from the upper roller box. In the second position state, at least a portion of the first surface of the first adjustment structure presses against the upper roller box. The second adjustment structure is located between the gate and the lower roller box, and the second power structure is connected to the second adjustment structure and is used to switch the second adjustment structure between a third position state and a fourth position state.

[0017] The second wedge is positioned opposite and spaced apart from the first wedge; the vertical surface of the second wedge is fixedly connected to the archway; an accommodating space is formed between the inclined surfaces of the first and second wedges.

[0018] The inclined wedge head has one end connected to the second power structure for driving. The second power structure is used to drive the inclined wedge head to simultaneously press against the inclined surfaces of the first and second inclined wedge blocks, or to drive the inclined wedge head away from the first and second inclined wedge blocks, so that the second adjustment structure can switch between the third and fourth position states.

[0019] In one implementation, a first groove is formed on the inclined surface of the first wedge block, and the extension direction of the first groove is consistent with the inclination direction of the inclined surface of the first wedge block; the wedge head has a first inclined surface that matches the inclined surface of the first wedge block, and a first protrusion that matches the first groove is provided on the first inclined surface, and the first protrusion can be slidably fitted into the first groove.

[0020] The second wedge has a second groove on its inclined surface, and the extension direction of the second groove is consistent with the inclination direction of the inclined surface of the second wedge. The wedge head has a second inclined surface that matches the inclined surface of the second wedge, and a second protrusion that matches the second groove is provided on the second inclined surface. The second protrusion can be slidably fitted into the second groove.

[0021] In one implementation, the wedge head has a first inclined surface that matches the inclined surface of the first wedge block, and a second inclined surface that matches the inclined surface of the second wedge block;

[0022] The adjustment device also includes: multiple second sensors connected to the controller; multiple second sensors are respectively disposed on the first inclined plane and the second inclined plane; the second sensors are used to detect the distance between the inclined wedge head and the first inclined wedge block and the distance between the inclined wedge head and the second inclined wedge block.

[0023] In one implementation, the second power structure includes: a motor connected to a controller; a first commutator, the motor being poweredly connected to the first commutator; a second commutator connected to the first commutator via a first connecting rod; a screw lifting assembly connected to the second commutator via a transmission link; a second connecting rod, one end of which is connected to the screw lifting assembly; a third connecting rod, the other end of which is connected to one end of the third connecting rod via a pin; and the other end of the third connecting rod is connected to a second adjusting structure.

[0024] In one implementation, the adjusting device further includes: a sleeve fitted onto the third connecting rod and fixedly connected to the third connecting rod; two connecting plates arranged opposite to each other and spaced apart, with the sleeve located between the two connecting plates; the two connecting plates are respectively used to abut against the lower roller box and the archway; a plurality of guide rods, the first end of which is fixedly connected to the connecting plate, and the second end of which passes through the sleeve; the guide rods can move axially relative to the sleeve under the action of external force; a plurality of elastic elements fitted onto the guide rods, with the elastic elements located between the sleeve and the connecting plates; when the two connecting plates abut against the lower roller box and the archway respectively, the elastic elements are in a compressed state and have a compression allowance.

[0025] In one implementation, the adjusting device further includes: a rotating member; at least one through groove is provided on the connecting plate along the thickness direction; the rotating member is located in the through groove and is rotatably connected to the inner wall of the through groove; the rotating member is in rolling contact with both the lower roller box and the archway.

[0026] Compared with the prior art, the beneficial effects of this application are as follows:

[0027] In the adjustment device provided by this invention, since the second surface of the first adjustment structure is fixedly connected to the archway, and when the first adjustment structure is in the second position, at least a portion of the first surface of the first adjustment structure presses against the upper roller box. When the second adjustment structure is in the third position, the second adjustment structure simultaneously presses against the archway and the lower roller box. Therefore, during the actual operation of the straightening machine, the controller activates the first power structure to put the first adjustment structure in the second position, and the controller activates the second power structure to put the second adjustment structure in the third position. At this time, the upper roller box and the archway form a rigid body through the first adjustment structure, and the lower roller box and the archway form a rigid body through the second adjustment structure. This makes the upper roller box, the archway, and the lower roller box form a single rigid body, thereby reducing or eliminating horizontal vibration and eliminating the probability of the roller box continuously colliding with the archway because the roller box and the archway are not a rigid body, thus extending the service life of the archway. Furthermore, by reducing or eliminating horizontal vibration and eliminating the probability of the roller box continuously impacting the arch, the instantaneous, high-frequency impact load generated by the impact of the roller box and the arch can be reduced or eliminated, thereby reducing or eliminating the damage caused by the impact load to the straightening roller system, thus extending the service life of the straightening roller system and the service life of the straightening machine.

[0028] Secondly, the present invention also provides a straightening machine. The straightening machine includes a frame, a roller box, support rollers, straightening rollers, and the adjusting device described in the above-mentioned technical solution. The roller box and the frame are spaced apart; along the height direction of the straightening machine, the roller box includes an upper roller box and a lower roller box. Along the height direction of the straightening machine, the support roller includes an upper support roller and a lower support roller. Along the height direction of the straightening machine, the straightening roller includes an upper straightening roller and a lower straightening roller.

Along the height direction of the straightening machine, the upper support roller is located above the upper straightening roller, and the lower support roller is located below the lower straightening roller.

[0029] The beneficial effects of the straightening machine provided by this invention are the same as those of the adjustment device described in the above technical solution, and will not be repeated here. Attached Figure Description

Detailed Implementation

[0048] To facilitate a clear description of the technical solutions in the embodiments of the present invention, the terms "first" and "second" are used to distinguish identical or similar items with essentially the same function and effect. For example, the first threshold and the second threshold are merely used to distinguish different thresholds and do not limit their order. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and that the terms "first" and "second" are not necessarily different.

[0049] It should be noted that in this invention, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this invention should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0050] In this invention, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, a combination of a and b, a combination of a and c, a combination of b and c, or a, b, and c, where a, b, and c can be single or multiple.

[0051] Pickled steel sheets (e.g., 1mm-6mm thick) are products made by pickling hot-rolled steel sheets to remove iron oxide scale. They inherit the characteristics of hot-rolled steel sheets but also place higher demands on surface quality and sheet shape. See also Figure 1 and Figure 2 The 17-roll straightener is an important finishing equipment in the pickling plate production line. It includes a straightening roll system, which comprises straightening rolls and support rolls. The 17-roll straightener also includes a main unit, bearings, a transmission system, and spaced-apart roll boxes 2 and archways 1. The support rolls are installed within the roll boxes 2. It should be noted that the specific positional and connection relationships between the various structures included in the 17-roll straightener are detailed in existing technology and will not be elaborated upon here.

[0052] In actual operation, by precisely adjusting the pressure and bending amount of each row of straightening rollers, different plastic stretching can be applied to different areas along the width of the workpiece to be processed (such as pickled plates, steel plates, or metal strips). However, during long-term operation, the straightening rollers will continuously rub against the high-temperature, high-strength steel or metal strips, inevitably causing wear. At this point, the roller surface will gradually wear down, losing its original smoothness and becoming rough. This will directly leave scratches, indentations, or pits on the surface of the straightened metal material, severely affecting the product surface quality. Furthermore, uneven wear will cause dynamic imbalance when the straightening rollers rotate at high speeds, resulting in severe vibration and abnormal noise in the equipment. This not only affects product quality but also damages the main unit, bearings, and transmission system of the straightening machine. Therefore, the straightening roller system needs to be replaced regularly.

[0053] To enable rapid online replacement of straightening rollers, a functional gap (approximately 1mm-2mm) is reserved between the roller box and the archway. However, during the straightening process of pickled plates, the straightening speed reaches 2m / s-4m / s, and the enormous straightening force is transmitted to the archway 1 through the straightening roller system and roller box. Due to the aforementioned functional gap, the roller box and archway 1 are not an absolutely rigid whole, resulting in the roller box continuously impacting the archway 1 during the actual straightening process, causing the roller box to vibrate horizontally within the window of archway 1. For example, during straightening, the straightening rollers apply horizontal squeezing and bending forces to the workpiece to be processed, and the reaction force of the workpiece to be processed will cause horizontal vibration of the straightening machine (e.g., the roller box included in the straightening machine).

[0054] Furthermore, the straightening roller system is designed to withstand stable static loads or uniform dynamic loads. However, the impact between the roller box and the archway 1 generates instantaneous, high-frequency impact loads (the peak impact force can reach several times or even more than ten times the normal operating load), exceeding the original design load. These impact loads directly damage the straightening roller system, shortening its lifespan and consequently affecting the service life of the straightener. For example, the huge impact load on the straightening roller system causes wear on the support roller surface. Simultaneously, the bearings of the support rollers are also subjected to a huge impact force far exceeding the rated static load. This force acts directly on the bearing balls and raceways through the bearing housing, causing the bearing raceways to peel off and burn, leading to premature bearing failure and shortened service life. The severe vibration also destroys the lubricating oil film formed between the bearing balls and raceways, causing direct metal-to-metal contact and dry friction, rapidly leading to bearing overheating, seizing, and scrapping, resulting in huge economic losses.

[0055] To address at least one of the aforementioned technical problems, in a first aspect, embodiments of the present invention provide an adjustment device. See also... Figures 1 to 4 The adjusting device is applied to the straightening machine, which includes a frame 1 and roller boxes 2 spaced apart. Along the height direction E of the straightening machine, the roller box 2 includes an upper roller box 20 and a lower roller box 21. The specific positional and connection relationships between the frame 1, the upper roller box 20, and the lower roller box 21, as well as their shapes and materials, are not specifically limited here; reference can be made to existing technologies. For example, the frame 1 can be understood as a frame, with the upper roller box 20 and the lower roller box 21 housed within the frame (i.e., within the accommodating space of the frame), and both the upper roller box 20 and the lower roller box 21 are spaced apart from the frame.

[0056] For example, the above-mentioned straightening machine can be a seventeen-roll straightening machine; specifically, it can be a seventeen-roll straightening machine for a thin plate pickling production line. The thickness of the thin plate can range from 1mm to 2mm.

[0057] See Figures 1 to 11The adjusting device includes: a first adjusting structure 3, a first power structure, a second adjusting structure 5, a second power structure 6, and a controller. The first adjusting structure 3 is located between the archway 1 and the upper roller box 20. The first adjusting structure 3 has opposing first and second surfaces. The first surface of the first adjusting structure 3 faces the upper roller box 20, and the second surface of the first adjusting structure 3 is fixedly connected to the archway 1. The first power structure is connected to the first adjusting structure 3 and is used to switch the first adjusting structure 3 between a first position state and a second position state. In the first position state, the first surface of the first adjusting structure 3 is spaced apart from the upper roller box 20. In the second position state, at least a portion of the first surface of the first adjusting structure 3 presses against the upper roller box 20. The second adjusting structure 5 is located between the archway 1 and the lower roller box 21. The second power structure 6 is connected to the second adjusting structure 5 and is used to switch the second adjusting structure 5 between a third position state and a fourth position state. In the third position state, the second adjusting structure 5 simultaneously presses against both the archway 1 and the lower roller box 21. In the fourth position state, the second adjusting structure 5 does not press against either the archway 1 or the lower roller box 21. The controller is connected to the first power structure and the second power structure 6 respectively. The above "the second adjusting structure 5 does not press the archway 1 and the lower roller box 21" can be understood as the second adjusting structure 5 only contacting the archway 1 and the lower roller box 21 simultaneously but not pressing them together, or the second adjusting structure 5 not connecting the archway 1 and the lower roller box 21 together.

[0058] See Figures 1 to 11Compared with the prior art, the beneficial effects of this application are as follows: In the adjustment device provided by the embodiments of the present invention, since the second surface of the first adjustment structure 3 is fixedly connected to the archway 1, and when the first adjustment structure 3 is in the second position state, at least a portion of the first surface of the first adjustment structure 3 presses against the upper roller box 20. When the second adjustment structure 5 is in the third position state, the second adjustment structure 5 simultaneously presses against the archway 1 and the lower roller box 21. Therefore, in the actual operation of the straightening machine, the controller activates the first power structure to make the first adjustment structure 3 in the second position state, and the controller activates the second power structure 6 to make the second adjustment structure 5 in the third position state. At this time, the upper roller box 20 and the archway 1 form a rigid body through the first adjustment structure 3, and the lower roller box 21 and the archway 1 form a rigid body through the second adjustment structure 5, thereby making the upper roller box 20, the archway 1 and the lower roller box 21 form a rigid body, thereby reducing or eliminating horizontal vibration, and eliminating the probability that the roller box 2 will continuously hit the archway 1 because the roller box 2 and the archway 1 are not a rigid body, thereby extending the service life of the archway. Furthermore, by reducing or eliminating horizontal vibration and eliminating the probability of roller box 2 continuously impacting arch 1, the instantaneous, high-frequency impact load generated by the impact between roller box 2 and arch 1 can be reduced or eliminated, thereby reducing or eliminating the damage caused by this impact load to the straightening roller system, extending the service life of the straightening roller system, and thus extending the service life of the straightener. Furthermore, the enormous impact force on the bearings of the support rollers can also be reduced or eliminated, extending the bearing life, and thus extending the service life of the straightener. In addition, the adjustment device provided in this application can also prevent the destruction of the lubricating oil film formed between the bearing rollers and raceways due to severe vibration, avoiding direct metal-to-metal contact, dry friction, and the rapid occurrence of bearing overheating, seizing, and failure.

[0059] It should be noted that the aforementioned "rigid body" is not limited by the materials of the first adjustment structure 3 and the second adjustment structure 5. The materials used to form the first adjustment structure 3 and the second adjustment structure 5 can be steel, plastic, or wood. As long as the condition of "the distance between two internal points remains unchanged or changes very little" is met, it can be defined as a rigid body, and the material does not change the core properties of this model.

[0060] Furthermore, when replacing the straightening rollers or when the straightening roller system needs to be tilted, the controller activates the first power structure to switch the first adjusting structure 3 from the second position to the first position, and activates the second power structure 6 to switch the second adjusting structure 5 from the third position to the fourth position. At this time, the upper roller box 20 and the archway 1 are disconnected, and the upper roller box 20 and the archway 1 are spaced apart. The archway 1 and the lower roller box 21 are also disconnected, and the archway 1 and the lower roller box 21 are spaced apart. That is, the distance between the upper roller box 20 and the archway 1, and the distance between the archway 1 and the lower roller box 21 are restored, so as to facilitate the disassembly and replacement of the straightening rollers or the tilting adjustment of the straightening roller system.

[0061] As one possible implementation, see Figure 3 The second side of the first adjusting structure 3 can be fixedly connected to the archway 1 by bonding, welding or using countersunk screws.

[0062] In some embodiments, see Figure 5 and Figure 6 The second surface of the first adjustment structure 3 has multiple countersunk holes 90, and the second surface of the first adjustment structure 3 and the archway 1 are fixedly connected by countersunk screws set in the countersunk holes 90.

[0063] The aforementioned controller can be a PLC (Programmable Logic Controller).

[0064] As one possible implementation, see Figure 3 , Figures 5 to 7 The first adjusting structure 3 includes a first adjusting plate 30 and at least two second adjusting plates 31. The first adjusting plate 30 has opposing first and second end faces. Along the length direction L of the first adjusting plate 30, the first adjusting plate 30 includes an end region 32 and an intermediate region 33 located between the two end regions 32. The thickness of the first adjusting plate 30 located in the end region 32 is less than the thickness of the first adjusting plate 30 located in the intermediate region 33. At least one annular groove 34 and at least one cavity 35 are formed on the first end face of each end region 32, and the annular groove 34 is correspondingly arranged around the periphery of the cavity 35. The second end face is fixedly connected to the archway 1, and a liquid inlet 36 is formed on the side of the first adjusting plate 30, which communicates with the cavity 35. At least two second adjusting plates 31 each have a third end face and a fourth end face, the third end face matching the first end face, and the fourth end face facing the upper roller box 20. Each third end face mates with the corresponding recess 35 to form a cavity, which is used to contain hydraulic oil. The first adjusting plate 30 and the second adjusting plate 31 are fixedly connected.

[0065] In one alternative approach, see Figures 5 to 7 The third end face of the second adjusting plate 31 is provided with a raised annular wall 37, which matches the annular groove 34. When the second adjusting plate 31 and the first adjusting plate 30 are combined, the raised annular wall 37 is embedded in the annular groove 34, the third end face of the second adjusting plate 31 covers the first end face of the first adjusting plate 30, and the third end face engages with the recess 35 to form a closed cavity.

[0066] In one alternative approach, see Figures 5 to 7 Each end region 32 has two annular grooves 34 and two cavities 35. The first adjustment structure 3 includes four second adjustment plates 31.

[0067] See Figure 3 , Figures 5 to 7 The first power structure includes a hydraulic pump and a hydraulic oil storage unit. The adjustment device also includes a first sensor 4. The hydraulic pump is connected to a controller and to the hydraulic oil storage unit. The hydraulic oil storage unit stores hydraulic oil and is connected to an inlet 36 to supply hydraulic oil to the cavity. The first sensor 4 is located in the middle region 33 of the first adjustment plate 30. The first sensor 4 is used to detect the distance between the first surface of the first adjustment structure 3 and the upper roller box 20. The controller is connected to the first sensor 4. For example, the first sensor 4 can be a miniature laser sensor.

[0068] See Figure 3 , Figures 5 to 7 When the cavity needs to expand, the controller activates the hydraulic pump, allowing hydraulic oil from the hydraulic oil storage unit to enter the cavity through the inlet 36. This increases the pressure within the cavity, causing it to expand. Consequently, the areas of the second adjusting plate 31 and the first adjusting plate 30 located in the end region 32 that correspond to the cavity bulge outwards. As the cavity expands, when the fourth end face of the second adjusting plate 31 (i.e., at least a portion of the first face of the first adjusting structure 3) is in close contact with the upper roller box 20, the first adjusting structure 3 is in a second position, thus eliminating the gap between the upper roller box 20 and the archway 1 corresponding to the area where the first adjusting structure 3 is located.

[0069] See Figure 3 , Figures 5 to 7 In actual operation, the first sensor 4 is also used to detect whether the distance between the upper roller box 20 and the fourth end face of the second adjusting plate 31 will cause a jump exceeding a preset value. If it exceeds the preset value, it indicates that there may be contact between the first adjusting structure 3 and the upper roller box 20, but they are not locked tightly. In this case, the cavity still needs to expand. The controller further performs oil filling and pressurization. It should be noted that the pressure in the cavity is increased slowly and should not exceed the preset pressure limit.

[0070] See Figure 3 , Figures 5 to 7 When the first adjustment structure 3 needs to be changed from the second position state to the first position state, the controller controls the solenoid valve to open the return oil circuit, so that part of the liquid flows back to the hydraulic oil storage component to reduce the pressure in the cavity, so that the areas of the second adjustment plate 31 and the first adjustment plate 30 located in the end region 32 corresponding to the cavity return to their original state, thereby so that the first surface of the first adjustment structure 3 is spaced apart from the upper roller box 20.

[0071] It should be noted that the preceding description states that "increasing the pressure within the cavity causes the cavity to expand, thereby causing the regions of the second adjusting plate 31 and the first adjusting plate 30 located in the end region 32 corresponding to the cavity to bulge outwards." Therefore, the fourth end face of the second adjusting plate 31 bulges outwards. However, the first end face of the first adjusting plate 30 located in the middle region 33 does not bulge outwards. Therefore, the first end face in the middle region 33 and the fourth end face of the second adjusting plate 31 are not on the same plane. The "first surface of the first adjusting structure 3" described above includes the fourth end face of the second adjusting plate 31 and the first end face located in the middle region 33. Here, the first surface of the first adjusting structure 3 is a relative concept; it is a surface relative to the second surface of the first adjusting structure 3, and it does not restrict the first surface to necessarily be a plane.

[0072] In one alternative approach, see Figure 5 and Figure 6 A first gap exists between the first adjusting plate 30 located in the intermediate region 33 and the adjacent second adjusting plate 31. A second gap exists between two adjacent second adjusting plates 31 located on the same side of the intermediate region 33.

[0073] See Figure 5 and Figure 6 When the second adjusting plate 31 expands during operation, the first gap and the second gap provide the second adjusting plate 31 with room to expand, avoiding the risk of cracking and deformation caused by mutual compression between structures, and improving the structural safety and reliability of the first adjusting structure 3. Specifically, the first gap can prevent the expansion and deformation of the second adjusting plate 31 from compressing the first adjusting plate 30 located in the middle region 33, and the second gap can prevent the deformation of two adjacent second adjusting plates 31 from causing compression.

[0074] See Figure 5 The first gap and the second gap may be equal or unequal. Further, the range of values ​​for the first gap and the second gap can be set according to the dimensions of the first adjusting plate 30 and the second adjusting plate 31. In some embodiments, the width W1 of the first gap is 1mm to 2mm, and the width W2 of the second gap is 1mm to 2mm. For example, the width of the first gap or the second gap may be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, or 2mm, etc.

[0075] In one alternative approach, see Figure 5 Before the first adjustment structure 3 expands, the total thickness of the second adjustment plate 31 and the first adjustment plate 30 located in the end region 32 after being fixedly connected is equal to the thickness of the first adjustment plate 30 located in the middle region 33.

[0076] In one alternative approach, see Figures 5 to 7 The first adjusting plate 30 and the second adjusting plate 31 are both provided with countersunk holes 90, and the first adjusting plate 30 and the second adjusting plate 31 are fixedly connected by countersunk screws provided in the countersunk holes 90.

[0077] See Figures 5 to 7 At this time, it is possible to avoid the fasteners (such as bolts) used to connect and fix the first adjusting plate 30 and the second adjusting plate 31 from protruding from the outer surfaces of the first adjusting plate 30 and the second adjusting plate 31, so as to avoid the fasteners from contacting the upper roller box 20 before the second adjusting plate 31, thereby avoiding affecting the second adjusting plate 31 pressing the upper roller box 20.

[0078] As one possible implementation, see Figure 4 , Figures 8 to 11 The second adjusting structure 5 includes a first inclined wedge 50, a second inclined wedge 51, and an inclined wedge head 52. The vertical surface of the first inclined wedge 50 is fixedly connected to the lower roller box 21, and the second inclined wedge 51 is opposite to and spaced apart from the first inclined wedge 50. The vertical surface of the second inclined wedge 51 is fixedly connected to the archway 1, and an accommodating space (i.e., a wedge-shaped opening) is formed between the inclined surfaces of the first and second inclined wedges 50 and 51. One end of the inclined wedge head 52 is driven by a second power structure 6, which drives the inclined wedge head 52 to simultaneously press against the inclined surfaces of the first and second inclined wedges 50 and 51, or to move the inclined wedge head 52 away from the first and second inclined wedges 50 and 51, so that the second adjusting structure 5 can switch between a third position and a fourth position.

[0079] The materials and dimensions of the first wedge block 50, the second wedge block 51, and the wedge head 52 can be set according to actual needs, and no specific limitations are made here.

[0080] In some embodiments, the first wedge block 50 and the second wedge block 51 have identical specifications. The following description uses the first wedge block 50 as an example. It should be noted that the following description is for understanding purposes only and is not intended to limit the specific application.

[0081] See Figure 4 , Figures 8 to 11 Along the height direction E of the straightener, the cross-sectional shape of the first wedge block 50 is trapezoidal. The first wedge block 50 includes two opposing vertical surfaces. The two vertical surfaces are a first vertical surface and a second vertical surface, respectively. The size of the first vertical surface is smaller than that of the second vertical surface. The second vertical surface is fixedly connected to the lower roller box 21. The first vertical surface faces the second wedge block 50. The inclined surface of the first wedge block 50 connects the first vertical surface and the second vertical surface.

[0082] In one alternative approach, see Figure 4 , Figures 8 to 11 Along the height direction H1 of the wedge head 52, the wedge head 52 includes a first part 520 and a second part 521. The first part 520 has a first inclined surface that matches the inclined surface of the first wedge block 50, and a second inclined surface that matches the inclined surface 510 of the second wedge block 51. The second part 521 is cuboid in shape.

[0083] See Figure 4 , Figures 8 to 11 When the second adjusting structure 5 is in the third position, the second power structure 6 drives the inclined wedge head 52 to move closer to the first inclined wedge block 50 and the second inclined wedge block 51, so that the first inclined surface of the inclined wedge head 52 presses against the inclined surface of the first inclined wedge block 50, and the second inclined surface of the inclined wedge head 52 presses against the inclined surface of the second inclined wedge block 51. At this time, the second adjusting structure 5 exerts a squeezing effect on the lower roller box 21 and the archway 1, eliminating the gap between the lower roller box 21 and the archway 1 at the position of the second adjusting structure 5, so that the lower roller box 21, the first inclined wedge block 50, the inclined wedge head 52, the second inclined wedge block 51 and the archway 1 form a rigid body.

[0084] When the second adjustment structure 5 changes from the third position to the fourth position, the second power structure 6 drives the inclined wedge head 52 to move away from the first inclined wedge block 50 and the second inclined wedge block 51, so that the first inclined surface of the inclined wedge head 52 and the inclined surface of the first inclined wedge block 50 are distributed alternately, and the second inclined surface of the inclined wedge head 52 and the inclined surface of the second inclined wedge block 51 are distributed alternately.

[0085] In one alternative approach, see Figures 8 to 11 The first wedge block 50 has a first groove on its inclined surface, and the extension direction of the first groove is consistent with the inclination direction of the inclined surface of the first wedge block 50. The wedge head 52 has a first inclined surface that matches the inclined surface of the first wedge block 50, and a first protrusion 522 that matches the first groove is provided on the first inclined surface. The first protrusion 522 can be slidably fitted into the first groove.

[0086] In one alternative approach, see Figures 8 to 11 The second wedge block 51 has a second groove 511 on its inclined surface, and the extension direction of the second groove 511 is consistent with the inclination direction N of the inclined surface of the second wedge block 51. The wedge head 52 has a second inclined surface that matches the inclined surface of the second wedge block 51, and a second protrusion 523 that matches the second groove 511 is provided on the second inclined surface. The second protrusion 523 can be slidably fitted into the second groove 511.

[0087] See Figures 8 to 11For ease of subsequent description, the inclined surface 510 of the second wedge block 51 is divided into a first region 512, a second region 513, and a third region 514, with the second groove 511 located in the second region 513. The second inclined surface is divided into a fourth region 524, a fifth region 525, and a sixth region 526, with the second protrusion 523 located in the fifth region 525.

[0088] See Figures 8 to 11 When the second adjusting structure 5 is in the third position, the inclined wedge head 52 is embedded in the receiving space. The first region 512 contacts and presses against the sixth region 526, the second region 513 contacts and presses against the fifth region 525, and the third region 514 contacts and presses against the fourth region 524. The second protrusion 523 is embedded in the second groove 511. The relative positional relationship between the inclined wedge head 52 and the first inclined wedge plate is similar. By pressing the inclined wedge head 52 against the first and second inclined wedge plates, the movement of the lower roller box 21 in the x-axis direction can be prevented. The friction generated by the pressing can prevent movement in the y-axis. Specifically, if the tendency of movement in the y-axis is too large, and the force of movement is greater than the friction force, the first and second inclined surfaces of the inclined wedge head 52 with the first protrusion 522 and the second protrusion 523 will respectively press against the inclined surfaces of the first and second inclined wedge plates with the first and second grooves 511, preventing the lower roller box 21 from moving in the y-axis direction. It should be noted that the x-axis direction is perpendicular to the y-axis direction.

[0089] As one possible implementation, see Figure 4 , Figures 8 to 11 The adjustment device further includes multiple second sensors 7, each connected to the controller. The multiple second sensors 7 are respectively disposed on the first inclined plane and the second inclined plane. The second sensors 7 are used to detect the distance between the inclined wedge head 52 and the first inclined wedge block 50, as well as the distance between the inclined wedge head 52 and the second inclined wedge block 51, so as to facilitate the switching of the second adjustment structure 5 between the third position state and the fourth position state.

[0090] For example, the second sensor 7 may be a miniature laser sensor, which is located at the midpoint between the first and second inclined planes.

[0091] In summary, since the adjustment device of this application includes a first sensor 4 and a second sensor 7, this application does not adjust the gap in a unidirectional linear manner, but can adaptively adjust according to the data fed back by the first sensor 4 and the second sensor 7, so as to prevent the situation of contact but not being locked.

[0092] As one possible implementation, see Figure 4 and Figure 11The second power structure 6 includes: a motor 60, a first commutator 68, a second commutator 61, a screw lifting assembly 62, a first connecting rod 63, a second connecting rod 64, and a third connecting rod 65. The motor 60 is powered by the first commutator 68. The second commutator 61 is connected to the first commutator 68 via the first connecting rod 63. The screw lifting assembly 62 is connected to the second commutator 61 via a transmission link 67. One end of the second connecting rod 64 is connected to the screw lifting assembly 62. The other end of the second connecting rod 64 is connected to one end of the third connecting rod 65 via a pin 66. The other end of the third connecting rod 65 is connected to the second adjusting structure 5.

[0093] See Figure 4 and Figure 11 Since the other end of the second connecting rod 64 is connected to one end of the third connecting rod 65 via a pin 66, it can prevent the lower roller box 21 from moving along the x-axis when the straightener is actually working under the condition that the second adjusting structure 5 is simultaneously pressing the archway 1 and the lower roller box 21. This prevents the lower roller box 21 from driving the inclined wedge head 52 included in the second adjusting structure 5, which in turn drives the third connecting rod 65, which in turn drives the second connecting rod 64, which in turn drives the motor 60 to move. This avoids damage to the motor 60 and extends the service life of the adjusting device. Furthermore, it can also prevent vibrations in the direction of the motor 60 from being transmitted to the third connecting rod 65 via the second connecting rod 64, thus preventing the lower roller box 21 from moving along the x-axis.

[0094] In some embodiments, see Figure 4 and Figure 11 The second connecting rod 64 and the third connecting rod 65 are perpendicular to each other.

[0095] In some embodiments, see Figure 1 , Figure 4 and Figure 11 The aforementioned adjustment device includes four second adjustment structures 5, one motor 60, one first commutator 68, and two second commutators 61. The first commutator 68 is simultaneously connected to both second commutators 61. The "transmission link 67, screw lifting assembly 62, second connecting rod 64, and third connecting rod 65" form a power transmission assembly, with each second commutator 61 connecting two sets of power transmission assemblies. The four second adjustment structures 5 correspond to the four positions of the archway 1, and their lifting effects are synchronized. That is, the second power structure 6 drives the four second adjustment structures 5 to rise or fall simultaneously and synchronously.

[0096] The aforementioned motor 60 can be a lifting motor. The structure of the first commutator 68, the second commutator 61, the transmission link 67, the screw lifting assembly 62, the first connecting rod 63, the second connecting rod 64, and the third connecting rod 65 is not specifically limited here, as long as it can meet the actual needs.

[0097] As one possible implementation, see Figure 4 , Figure 12 and Figure 13 The adjusting device also includes: a sleeve 80, two connecting plates 81 that are opposite to each other and spaced apart, a plurality of guide rods 82 and a plurality of elastic elements 83.

[0098] See Figure 4 , Figure 12 and Figure 13 Along the height direction H2 of the sleeve 80, the sleeve 80 has a through hole. The sleeve 80 is sleeved on the third connecting rod 65 through the through hole, and the sleeve 80 is fixedly connected to the third connecting rod 65. Two connecting plates 81 are arranged opposite to each other and spaced apart, with the sleeve 80 located between the two connecting plates 81. The two connecting plates 81 are respectively used to abut against the lower roller box 21 and the archway 1. The first end of the guide rod 82 is fixedly connected to the connecting plate 81, and the second end of the guide rod 82 passes through the sleeve 80. For example, at least part of the guide rod 82 is located inside the sleeve 80. Under the action of external force, the guide rod 82 can move relative to the sleeve 80 along the axial direction D of the guide rod 82. Multiple elastic elements 83 are correspondingly sleeved on the multiple guide rods 82, and the elastic elements 83 are located between the sleeve 80 and the connecting plates 81. When the two connecting plates 81 abut against the lower roller box 21 and the archway 1 respectively, the elastic elements 83 are in a compressed state and have a compression margin. For example, the elastic element 83 described above can be a spring.

[0099] The shape and material of the aforementioned sleeve 80, connecting plate 81, and guide rod 82 are not specifically limited here. In one alternative embodiment, see [reference needed]. Figure 4 , Figure 12 and Figure 13 The sleeve 80 is a cuboid sleeve with a through hole. The connecting plate 81 is a cuboid connecting plate, which facilitates the subsequent contact between the cuboid connecting plate and the lower roller box 21. The guide rod 82 is a cylindrical guide rod, which facilitates the movement of the cylindrical guide rod relative to the sleeve 80 in the first direction.

[0100] In some embodiments, see Figure 4 , Figure 12 and Figure 13 Along the direction perpendicular to the height H2 of the sleeve 80, a countersunk hole 90 is provided on the sleeve 80, and the countersunk bolts fix the sleeve 80 to the third connecting rod 65 through the countersunk hole 90.

[0101] See Figure 4 , Figure 12 and Figure 13 Under the action of external force, the guide rod 82 can move relative to the sleeve 80 along a first direction D, which is consistent with the direction from the first end to the second end of the guide rod 82. That is, the second end of the guide rod 82 can penetrate into the sleeve 80 (i.e., move towards the center point of the sleeve 80) or move away from the center point of the sleeve 80.

[0102] See Figure 4 , Figure 12 and Figure 13 For ease of description, the structure consisting of sleeve 80, two connecting plates 81, multiple guide rods 82, and multiple elastic elements 83 is defined as vibration-absorbing structure 8. When vibration-absorbing structure 8 is not installed between lower roller box 21 and archway 1, elastic elements 83 are in a state of neither compression nor extension. During the installation of vibration-absorbing structure 8 between lower roller box 21 and archway 1, the two connecting plates 81 are respectively used to abut against lower roller box 21 and archway 1, and both connecting plates 81 move towards sleeve 80. Since the connecting plates 81 are fixedly connected to the first end of guide rod 82, the connecting plates 81 push the second end of guide rod 82 towards a position closer to the center point of sleeve 80. During this process, connecting plates 81 compress elastic elements 83. After vibration-absorbing structure 8 is installed between lower roller box 21 and archway 1, elastic elements 83 are in a compressed state, and elastic elements 83 have a compression margin.

[0103] See Figure 4 , Figure 12 and Figure 13 If the second adjusting structure 5 does not simultaneously press the archway 1 and the lower roller box 21, the lower roller box 21 may move along the x-axis during actual operation of the straightener. When the adjusting device in this application includes the above-mentioned vibration-absorbing structure 8, the movement along the x-axis is transmitted to the connecting plate 81 through the lower roller box 21, and then to the elastic member 83 by the connecting plate 81. Since the elastic member 83 is in a compressed state, it has a compression margin, and the compression direction of the elastic member 83 is consistent with the x-axis direction. Therefore, the elastic member 83 can absorb part or all of the movement along the x-axis. It should be noted that because the elastic member 83 has a compression margin, it can utilize this margin to absorb the movement along the x-axis.

[0104] In one alternative approach, see Figure 4 , Figure 12 and Figure 13 The adjusting device further includes a rotating component 84. At least one through groove is formed on the connecting plate 81 along its thickness direction. The rotating component 84 is located within the through groove and is rotatably connected to the inner wall of the through groove. The rotating component 84 is in rolling contact with both the lower roller box 21 and the archway 1.

[0105] In some embodiments, the axial direction of the rotating member 84 is perpendicular to the direction of movement of the wedge head 52.

[0106] See Figure 4 , Figure 12 and Figure 13 When the motor 60 drives the wedge head 52 to move closer to the first wedge block 50, the third connecting rod 65 also moves closer to the first wedge block 50, thereby driving the vibration-absorbing structure 8 on the third connecting rod 65 to move closer to the first wedge block 50. Since the rotating part 84 is in rolling contact with both the lower roller box 21 and the archway 1, compared to the connecting plate 81 directly contacting the lower roller box 21 and the archway 1, the surface contact is transformed into rolling contact. When the rotating part 84 rotates, the friction between the rotating part 84 and the lower roller box 21 and the archway 1 is reduced, thus reducing the resistance of the vibration-absorbing structure 8 during its movement closer to the first wedge block 50, preventing any impact on the movement of the vibration-absorbing structure 8. Furthermore, it can also reduce or prevent wear damage to the lower roller box 21 and the archway 1.

[0107] The following describes the use of the regulating device using one possible implementation as an example. It should be noted that the following description is for understanding purposes only and is not intended to limit the specific implementation.

[0108] See Figures 1 to 13 In the first working state, when the second sensor 7 detects a gap between the wedge head 52 and the first wedge block 50 and the second wedge block 51, the controller starts the motor 60. The motor 60 drives the first commutator 68, which in turn drives the second commutator 61. The second commutator 61 then drives the screw lifting assembly 62, converting rotational motion into linear motion. This motion, along with the screw lifting assembly 62, causes the third connecting rod 65 to move the wedge head 52 closer to the first wedge block 50 and the second wedge block 51, until the second sensor 7 detects that the gap is zero. If, during actual operation, the second sensor 7 detects a rapid change in the gap value between the wedge head 52 and the first wedge block 50, or between the wedge head 52 and the second wedge block 51, and either gap value exceeds a first preset value, it indicates that the wedge head 52 is not pressing the first wedge block 50 and the second wedge block 51 firmly, requiring fine-tuning. Motor 60 will rotate briefly according to the controller's preset instruction program until the aforementioned gap values ​​no longer change rapidly.

[0109] When the first sensor detects a gap between the first surface of the first adjusting structure 3 and the upper roller box 20, the first sensor 4 transmits the detected gap data to the controller. The controller then controls the hydraulic pump and hydraulic oil storage device to inject hydraulic oil into the cavity of the first adjusting structure 3, increasing the pressure within the cavity and causing it to expand. This causes the areas of the second adjusting plate 31 and the first adjusting plate 30 located in the end region 32 corresponding to the cavity to bulge outwards until the first sensor 4 detects that the gap between the first surface of the first adjusting structure 3 and the upper roller box 20 is zero. If, during actual operation of the straightening machine, the first sensor 4 detects that the gap between the first surface of the first adjusting structure 3 and the upper roller box 20 changes rapidly and exceeds the second preset value, it indicates that the first surface of the first adjusting structure 3 is not pressing against the upper roller box 20. The controller's preset instruction program executes a brief pressurization and expansion (i.e., the hydraulic pump restarts to inject hydraulic oil into the cavity) until the rapid change in the gap value no longer occurs.

[0110] It should be noted that the first working state mentioned above can be understood as the state when the plate is straightened using a straightening machine.

[0111] When switching from the first working state to the second working state, the straightening roller system needs to tilt, thus requiring a certain gap between the roller box and the archway 1. At this time, the controller receives a tilting command for the straightening roller system and starts the motor 60. The motor 60 controls the inclined wedge head 52 to move away from the first inclined wedge block 50 and the second inclined wedge block 51. After the second sensor 7 detects a gap between the inclined wedge head 52 and the first and second inclined wedge blocks 50 and 51, the controller stops the motor 60. Next, the controller controls the hydraulic pump to reduce the pressure within the cavity of the first adjusting structure, restoring the first adjusting structure to its original state, i.e., creating a gap between the first surface of the first adjusting structure 3 and the upper roller box 20. When the first sensor 4 detects a gap between the first surface of the first adjusting structure 3 and the upper roller box 20, the controller stops the hydraulic pump.

[0112] When transitioning from the first working state to the straightening roll replacement preparation state, the controller receives a straightening roll replacement preparation command and starts the motor 60. The motor 60 controls the wedge head 52 to move away from the first wedge block 50 and the second wedge block 51. After the second sensor 7 detects a gap between the wedge head 52 and the first and second wedge blocks 50 and 51, the controller stops the motor 60. Next, the controller controls the hydraulic pump to reduce the pressure within the cavity of the first adjustment structure, restoring the first adjustment structure to its original state, i.e., creating a gap between the first surface of the first adjustment structure 3 and the upper roller box 20. When the first sensor 4 detects a gap between the first surface of the first adjustment structure 3 and the upper roller box 20, the controller stops the hydraulic pump.

[0113] Secondly, embodiments of the present invention also provide a straightening machine. See [link to previous section]. Figures 1 to 15 The straightening machine includes a frame 1, a roller box 2, support rollers, straightening rollers, and the adjustment device described in the above technical solution. The roller box 2 is spaced apart from the frame 1. Along the height direction E of the straightening machine, the roller box 2 includes an upper roller box 20 and a lower roller box 21. Along the height direction E of the straightening machine, the support rollers include an upper support roller 911 and a lower support roller 912. Along the height direction of the straightening machine, the straightening rollers include an upper straightening roller 101 and a lower straightening roller 102. Both the upper support roller 911 and the upper straightening roller 101 are located within the upper roller box 20, and both the lower support roller 912 and the lower straightening roller 102 are located within the lower roller box 21. Along the height direction E of the straightening machine, the upper support roller 911 is located above the upper straightening roller 101, and the lower support roller 912 is located below the lower straightening roller 102.

[0114] The beneficial effects of the straightening machine provided in this embodiment of the invention are the same as those of the adjustment device described in the above technical solution, and will not be repeated here.

[0115] For specific descriptions of the archway 1, roller box 2, support roller and straightening roller, please refer to the existing technology. No specific limitations are made here, as long as they can meet the actual needs.

[0116] In one embodiment, see Figures 1 to 15Along the height direction E of the straightener, the support rollers include an upper support roller 911 and a lower support roller 912, the roller box 2 includes an upper roller box 20 and a lower roller box 21, and the straightening rollers include an upper straightening roller 101 and a lower straightening roller 102. The upper support roller 911 is horizontally mounted in a bearing seat inside the upper roller box 20, which provides space for it. Both ends of the upper support roller 911 are connected to the bearing seats of the upper roller box 20 via bearings. The upper roller box 20 restricts the radial and axial displacement of the upper support roller 911, while also supporting it and allowing it to rotate freely. Along the height direction E of the straightener, the upper support roller 911 is located above the upper straightening roller 101, and the axial direction of the upper support roller 911 is parallel to the axial direction of the upper straightening roller 101, with the two in close contact. The upper support roller 911 and the upper straightening roller 101 are not directly fixed. The upper support roller 911 can counteract the reaction force of the workpiece (e.g., sheet metal) on the upper straightening roller 101 during straightening, ensuring the stable rotation of the upper straightening roller 101. The lower support roller 912 is horizontally installed in the bearing seat inside the lower roller box 21, which provides space for the lower support roller 912. Both ends of the lower support roller 912 are engaged with the bearing seats of the lower roller box 21 through bearings. The lower roller box 21 restricts the radial and axial displacement of the lower support roller 912, while supporting the lower support roller 912 and allowing it to rotate flexibly. Along the height direction E of the straightener, the lower support roller 912 is located below the lower straightening roller 102, and the axial direction of the lower support roller 912 is parallel to and closely fitted with the axial direction of the lower straightening roller 102. The lower support roller 912 and the lower straightening roller 102 are not directly fixed. The lower support roller 912 can counteract the reaction force of the workpiece (e.g., sheet metal) on the lower straightening roller 102 during straightening, ensuring the stable rotation of the lower straightening roller 102. It should be noted that...
