Description

Technical Field

[0001] The present invention relates to the technical field of tensioning devices, and more particularly to a damping cutting device. Background Art

[0002] In the steel coil production process, the coiled steel often needs to be transported to processing equipment for secondary heat treatment. To ensure the continuity of the secondary heat treatment, the joints of different steel coils are welded together. However, when the steel coils after secondary heat treatment are rewound, the surface flatness of the steel coil at the weld seam is low and needs to be trimmed. The trimmed steel coils lack tension, and the steel coils are prone to overlap or curling in the plane when rewinding in the coiler, which reduces the coil quality. Summary of the Invention

[0003] The present invention aims to at least partially address one of the technical problems in the related art. To this end, the present invention proposes a damping shearing device that, by adding a pinching and shearing mechanism that performs both tension adjustment and shearing functions, reduces the distance between the sheared end of the steel coil and the tension adjustment position, thereby improving the coiling quality of the steel coil.

[0004] The technical solution adopted by the present invention is to provide a damping cutting device, comprising: a frame; a feed conveyor belt, which is arranged on one side of the frame for feeding steel coils; a discharging guide plate, which is arranged on the other side of the frame away from the feed conveyor belt for discharging the steel coils; a clamping mechanism, which is arranged on the frame for clamping and fixing the steel coils; a pinching and cutting mechanism, which is arranged on the frame between the clamping mechanism and the discharging guide plate, the pinching and cutting mechanism has a knife head for cutting the steel coils; a guide roller, which is rotatably mounted on the frame near the feed conveyor belt; a rotation drive unit, which is fixedly mounted on the frame, the rotation drive unit having a drive shaft rotatable around a first axis, the drive shaft being connected to the guide roller for driving the guide roller to rotate.

[0005] With the above structure, the pinching and shearing mechanism combines tension adjustment and shearing functions. When winding a steel coil, the pinching and shearing mechanism is used to adjust the coil's tension. When the coil reaches the weld and requires shearing, the cutter head advances and shears the coil at the weld. Compared to existing solutions that utilize separate devices for cutting and tensioning, the present invention reduces the distance between the cutter head and the tension adjustment position. This reduces the tension-free portion of the coil and prevents the coils within this distance from overlapping or curling in the plane, thereby improving the coiling quality. This arrangement also makes the overall structure of the damping shearing device more compact, saving equipment costs and reducing waste.

[0006] According to one embodiment of the present invention, the clamping and cutting mechanism includes a first telescopic drive unit, a mounting plate, a tensioning roller and a support plate, the first telescopic drive unit is fixedly mounted on the frame, the mounting plate is fixedly mounted on the driving end of the first telescopic drive unit, the cutting head is provided on one edge of the mounting plate adjacent to the clamping mechanism, the tensioning roller and the support plate are both arranged on the mounting plate, and there is a gap between the tensioning roller and the support plate for the steel coil to pass through; the mounting plate is driven up and down by the first telescopic drive, and the mounting plate drives the tensioning roller and the support plate to move synchronously, and the roller surface of the tensioning roller is against the surface of the steel coil, thereby adjusting the tensioning force of the steel coil.

[0007] According to one embodiment of the present invention, the frame includes two side panels arranged in parallel and spaced apart, each of the side panels is provided with a slide groove, and two sliders slidingly engaged with the slide grooves are arranged in parallel and spaced apart on the mounting plate, and the tensioning roller is rotatably arranged between the two sliders.

[0008] According to one embodiment of the present invention, tooth plates are vertically provided on both side plates, and balance gears are coaxially provided at both ends of the tensioning roller, and the balance gears are meshed and connected with the tooth plates; since the axial length of the tensioning roller is longer than its radius, the setting of the balance gear tooth plates is used to balance the two ends of the tensioning roller to prevent the two ends of the tensioning roller from deviating from each other during the vertical movement and affecting the horizontality of the tensioning roller. During the vertical movement of the tensioning roller, the tensioning roller rotates synchronously with the rotation of the balance gear.

[0009] According to one embodiment of the present invention, one end of a buffer spring is connected to each of the two sliders, and the other end thereof is connected to the support plate, and the buffer spring has a tendency to cause the support plate to move away from the tensioning roller; the support plate has an extended edge extending into the slide groove, and the buffer spring is set so that there is space for relative movement between the slider and the support plate. When the extended edge on the slider is against the bottom of the slide groove, the support plate and the slider move relative to each other under the drive of the first telescopic drive unit, and the gap between the tensioning roller and the support plate gradually decreases.

[0010] According to one embodiment of the present invention, an avoidance portion is provided on the support plate corresponding to the cutter head, and the avoidance portion is formed by the edge of the support plate being inclined away from the cutter head; the avoidance portion is provided to provide feed space for the cutter head to avoid spatial steric obstruction between the cutter head and the support plate.

[0013] According to one embodiment of the present invention, the clamping surface of the first clamping plate has a first anti-slip contour, and the clamping surface of the second clamping plate has a second anti-slip contour.

[0014] According to one embodiment of the present invention, the damping cutting device further includes a coolant connector for connecting to an external coolant source, wherein the coolant connector is connected to a plurality of connecting pipes, wherein one of the connecting pipes is connected to the inner cavity of the guide roller.

[0040] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0041] like Figure 1As shown, this embodiment provides a damping cutting device, including: a frame 1; a feeding conveyor belt 2, which is arranged on one side of the frame 1 for feeding steel coils; a discharging guide plate 3, which is arranged on the other side of the frame 1 away from the feeding conveyor belt 2 for discharging the steel coils; a clamping mechanism 5, which is arranged on the frame 1 for clamping and fixing the steel coils; a pinching and cutting mechanism 4, which is arranged on the frame 1 between the clamping mechanism 5 and the discharging guide plate 3, the pinching and cutting mechanism 4 has a cutter head 10 for cutting the steel coils; a guide roller 7, which is rotatably mounted on the frame 1 near the feeding conveyor belt 2; a rotation drive unit 6, which is fixedly mounted on the frame 1, the rotation drive unit 6 has a drive shaft rotatable around a first axis, and the drive shaft is connected to the guide roller 7 for driving the guide roller 7 to rotate.

[0042] Furthermore, in this embodiment, the main body of the frame 1 is a table-like structure with a certain height, and two side panels 1a are vertically spaced apart on the table. The gap between the side panels 1a is the installation space for installing the clamping and cutting mechanism 4, the clamping mechanism 5 and the guide roller 7.

[0043] Further, combined with Figure 2 As shown, in this embodiment, the feed conveyor belt 2 includes a cross arm 21 and a plurality of rollers 22 provided on the cross arm 21. One end of the cross arm 21 is hinged to the frame 1 body, and the other end is a free end. The plurality of rollers 22 are evenly distributed along the length direction of the cross arm 21.

[0044] Furthermore, combined Figure 5 and Figure 6 As shown, a first tilt adjustment cylinder 23 is mounted on the frame 1 body. The cylinder body of the first tilt adjustment cylinder 23 is hinged to the frame 1 body, and the free end of its piston rod is hinged to the cross arm 21. The tilt angle of the cross arm 21 can be adjusted by adjusting the extension length of the piston rod of the first tilt adjustment cylinder 23.

[0045] Furthermore, in this embodiment, the discharge guide plate 3 includes a second tilt adjustment cylinder 31, a support plate 32, a blanking plate 33, and a blanking adjustment cylinder 34. One end of the support plate 32 is hinged to the main body of the frame 1, and the other end is a free end extending away from the main body of the frame 1. The cylinder body of the second tilt adjustment cylinder 31 is hinged to the main body of the frame 1, and the free end of its piston rod is hinged to the support plate 32. The tilt angle of the support plate 32 is adjusted by adjusting the extension length of the piston rod of the second tilt adjustment cylinder 31. The blanking plate 33 is slidably mounted on the surface of the support plate 32. The blanking adjustment cylinder 34 is fixedly mounted on the support plate 32. The free end of the piston rod of the blanking adjustment cylinder 34 is fixedly connected to the blanking plate 33, and is used to drive the blanking plate 33 to reciprocate along the surface of the support plate 32 toward or away from the main body of the frame 1.

[0046] Further, combined with Figure 3 and Figure 4 As shown, in this embodiment, the damping cutting device further includes an output roller 8 , which is configured on the frame 1 , and the output roller 8 is located between the pinching and cutting mechanism 4 and the discharge guide plate 3 .

[0047] Further, combined with Figure 9 and Figure 10 As shown, in this embodiment, a driven gear 81 is coaxially provided on the output roller 8 , and the driven gear 81 is meshedly connected with a gear-type encoder 82 .

[0048] Further, combined with Figure 11 As shown, the guide roller 7 comprises a roller body 71 and a fixed crossbar 73. The roller body 71 is connected to a plurality of spaced bosses 72, which extend from the surface of the roller body 71 away from the axis. A feeding gap is formed between the outer periphery of the bosses 72 and the fixed crossbar 73. This arrangement enables the guide roller 7 to both feed and separate multiple sheets of material.

[0049] Specifically, the clamping and cutting mechanism 4 includes a first telescopic drive unit 41, a mounting plate 42, a tensioning roller 46 and a support plate 47. The first telescopic drive unit 41 is fixedly mounted on the frame 1, and the mounting plate 42 is fixedly mounted on the driving end of the first telescopic drive unit 41. The cutting head 10 is provided on one side edge of the mounting plate 42 adjacent to the clamping mechanism 5. The tensioning roller 46 and the support plate 47 are both arranged on the mounting plate 42, and there is a gap between the tensioning roller 46 and the support plate 47 for the steel coil to pass through.

[0050] Further, combined with Figure 4 and Figure 7 As shown, the first telescopic drive unit 41 is vertically mounted on the upper portion of the frame 1, with the telescopic drive end of the first telescopic drive unit 41 facing downward and the mounting plate 42 positioned horizontally. The first telescopic drive unit 41 drives the mounting plate 42 to move up and down, which in turn drives the tensioning roller 46 and the support plate 47 to move synchronously. The roller surface of the tensioning roller 46 contacts the surface of the steel coil, thereby adjusting the tension of the steel coil.

[0051] Furthermore, in this embodiment, the cutter head 10 adopts an oblique blade design, that is, along the length direction of the cutter head 10, the blade surface is inclined from one end to the other end of the blade surface.

[0052] Specifically, the frame 1 includes two parallel and spaced side panels 1a, each of which is provided with a slide groove 1b, and the mounting plate 42 is provided with two parallel and spaced sliders 43 that slide with the slide groove 1b, and the tensioning roller 46 is rotatably arranged between the two sliders 43.

[0053] Furthermore, in the vertical direction, the mounting plate 42 has a certain thickness. In order to ensure that the mounting plate 42 is moved up and down stably by the first telescopic driving unit 41, structures that slide with the slide groove 1b are provided on both sides of the mounting plate 42.

[0054] Furthermore, two sliders 43 are vertically arranged and respectively configured on both sides of the mounting plate 42. Both ends of the tensioning roller 46 are rotatably matched with the sliders 43 respectively.

[0055] Specifically, a tooth plate 45 is vertically provided on each of the two side plates 1 a , and a balance gear 44 is coaxially provided at both ends of the tensioning roller 46 , and the balance gear 44 is meshed and connected with the tooth plate 45 .

[0056] Furthermore, since the axial length of the tensioning roller 46 is longer than its radius, the tooth plate 45 of the balance gear 44 is set to balance the two ends of the tensioning roller 46 to prevent the two ends of the tensioning roller 46 from deviating during the vertical movement and affecting the horizontality of the tensioning roller 46. During the vertical movement of the tensioning roller 46, the tensioning roller 46 rotates synchronously with the rotation of the balance gear 44.

[0057] Specifically, in another embodiment, one end of a buffer spring 11 is connected to each of the two sliders 43 , and the other end thereof is connected to the support plate 47 . The buffer spring 11 has a tendency to move the support plate 47 away from the tensioning roller 46 .

[0058] Furthermore, the support plate 47 has an extended edge extending into the slide groove 1b. The setting of the buffer spring 11 allows space for relative movement between the slider 43 and the support plate 47. When the extended edge on the slider 43 abuts against the bottom of the slide groove 1b, the support plate 47 and the slider 43 move relative to each other under the drive of the first telescopic drive unit 41, and the gap between the tensioning roller 46 and the support plate 47 gradually decreases.

[0059] Specifically, combined Figure 7 As shown, a relief portion 47 a is provided on the support plate 47 corresponding to the cutter head 10 , and the relief portion 47 a is formed by the edge of the support plate 47 being inclined away from the cutter head 10 .

[0060] Furthermore, the avoidance portion 47 a is provided to provide a space for the cutter head 10 to advance, thereby avoiding spatial steric obstruction between the cutter head 10 and the support plate 47 .

[0061] Specifically, the clamping mechanism 5 includes a second telescopic drive unit 51, a first clamping plate 52 and a second clamping plate 53. The second telescopic drive unit 51 and the second clamping plate 53 are both arranged on the frame 1. The driving end of the second telescopic drive unit 51 is fixedly connected to the first clamping plate 52, and is used to drive the first clamping plate 52 to move closer to or away from the second clamping plate 53.

[0062] Furthermore, the first clamping plate 52 and the second clamping plate 53 are arranged in a vertically corresponding manner. When the cutter head 10 is cutting, the edge of the second clamping plate 53 moves toward the cutting edge of the cutter head 10, generating a shear force on the steel coil. Therefore, the edge of the relief portion 47a adjacent to the second clamping plate 53 is lower than the height of the second clamping plate 53.

[0063] Furthermore, the vertical edge of the second clamping plate 53 adjacent to the support plate 47 is arranged adjacent to the outer edge of the support plate 47 so that the cut steel coil abuts against the vertical edge when it moves down toward the second clamping plate 53 .

[0064] Specifically, a first high-temperature resistant felt 54 is provided on the clamping surface of the first clamping plate 52, and a second high-temperature resistant felt 55 is provided on the clamping surface of the second clamping plate 53.

[0065] Furthermore, in this embodiment, the finished steel coil is BR1500, which is an automobile anti-collision steel. After heat treatment, the surface temperature of the steel coil reaches above 200°C. The high-temperature resistant felt has properties such as high temperature resistance and wear resistance, and can increase the clamping force on the steel coil surface.

[0066] Specifically, the first clamping plate 52 has a first anti-slip profile 52 a on its clamping surface, and the second clamping plate 53 has a second anti-slip profile 53 a on its clamping surface.

[0067] Furthermore, the clamping surfaces of the first clamping plate 52 and the second clamping plate 53 are arranged horizontally. Anti-slip grooves are provided on the clamping surface of the first clamping plate 52. These anti-slip grooves serve as a first anti-slip profile 52a to increase the friction between the first clamping plate 52 and the first high-temperature resistant felt 54. Similarly, anti-slip grooves are provided on the clamping surface of the second clamping plate 53. These anti-slip grooves serve as a second anti-slip profile 53a to increase the friction between the second clamping plate 53 and the second high-temperature resistant felt 55.

[0068] Specifically, combined Figure 1 As shown, the damping cutting device further includes a coolant connector 9 for connecting to an external coolant source. The coolant connector 9 is connected to a plurality of connecting pipes 91 , wherein one of the connecting pipes 91 is connected to the inner cavity of the guide roller 7 .

[0069] Furthermore, in this embodiment, a cooling pipe 46a is provided within the tension roller 46, and cooling channels are provided within the feed roller 8 and the first clamping plate 52. A coolant connector 9 is connected to the cooling pipe 46a and the cooling channel via a connecting pipe 91, respectively, and coolant is introduced. The coolant exchanges heat with the tension roller 46, guide roller 7, feed roller 8, and first clamping plate 52, thereby reducing their temperatures.

[0070] In this embodiment, the operating principle of the damping cutting device is as follows:

[0071] During normal operation, the hot steel coil is delivered to the frame 1 via the feed conveyor belt 2. The steel coil then passes through the guide roller 7, the gap between the tension roller 46 and the support plate 47, the gap between the first clamping plate 52 and the second clamping plate 53, the output roller 8, and the discharge guide plate 3 before being conveyed to the coiler. When the tension of the steel coil needs to be increased, the first telescopic drive unit 41 drives the mounting plate 42 downward, and the tension roller 46 and the support plate 47 move synchronously, so that the steel coil abuts against the lower roller surface of the tension roller 46 and the upper roller surface of the output roller 8, keeping the steel coil taut.

[0072] When the production line stops, in order to ensure the tension of the steel coil between the steel coil feeding end and the damping cutting device, the clamping mechanism 5 works, and the second telescopic drive unit 51 drives the first clamping plate 52 to move downward toward the second clamping plate 53 until the first clamping plate 52 and the second clamping plate 53 jointly clamp the steel coil.

[0073] When the weld seam on the steel coil moves to the predetermined position on the frame 1, the second telescopic drive unit 51 drives the first clamping plate 52 downward toward the second clamping plate 53 to securely clamp the steel coil. The first telescopic drive unit 41 then drives the mounting plate 42 downward, gradually tightening the steel coil between the first clamping plate 52 and the output roller 8. As the mounting plate 42 continues to move downward, one end of the blade surface of the cutter head 10 contacts the steel coil and, together with the second clamping plate 53, creates a shearing force. As the cutter head 10 advances, the shearing surface on the steel coil gradually shifts from one side of the steel coil width to the other until shearing is complete. During this process, under the action of the balance gear 44 and the tooth plate 45, the tension roller 46 rotates synchronously with the balance gear 44, causing slippage between the roller surface of the tension roller 46 and the steel coil.

[0074] In another embodiment, the damping cutting device is used in the following manner:

[0075] Another embodiment is different from this embodiment in that a buffer spring 11 is added between the slider 43 and the support plate 47 .

[0076] When the weld seam on the steel coil moves to the predetermined position on the frame 1, the second telescopic drive unit 51 drives the first clamping plate 52 to move downward toward the second clamping plate 53 to securely clamp the steel coil. The first telescopic drive unit 41 then drives the mounting plate 42 downward, gradually tightening the steel coil between the first clamping plate 52 and the output roller 8. As the mounting plate 42 continues to move downward, the extended portion of the support plate 47 abuts against the bottom of the chute 1b, causing the support plate 47 to stop moving downward. The tensioning roller 46 and the support plate 47 then move toward each other. The mounting plate 42 continues to move downward, causing the buffer spring 11 to continue to compress, and one end of the blade surface of the cutter head 10 contacts the steel coil until shearing is completed. During this process, under the action of the balance gear 44 and the tooth plate 45, the tensioning roller 46 rotates synchronously with the balance gear 44, causing the roller surface of the tensioning roller 46 to slide against the steel coil. After the steel coil is cut, the first telescopic drive unit 41 continues to move downward. Because the cross-section of the steel coil abuts the vertical edge of the second clamping plate 53, there is no room for the cut steel coil to move toward the clamping mechanism 5. Relative sliding occurs between the roller surface of the tension roller 46 and the steel coil. When the first telescopic drive unit 41 contracts, the mounting plate 42 drives the tension roller 46 upward. Under the action of the balance gear 44 and the tooth plate 45, the tension roller 46 moves in the opposite direction. The roller surface of the tension roller 46 exerts a reaction force on the steel coil, pushing the steel coil toward the output roller 8. This promptly breaks the contact between the steel coil cross-section and the side wall of the cutter head 10, preventing the cutter head 10 from driving the steel coil cross-section upward and causing overlap or curling within the plane, thereby improving the coiling quality. And the weld position is cut for the second time, the mounting plate 42 drives the tensioning roller 46 to move upward, and under the action of the balance gear 44 and the tooth plate 45, the tensioning roller 46 moves in the opposite direction, and the roller surface of the tensioning roller 46 exerts a reaction force on the steel coil, helping to push the waste cut off for the second time to be discharged toward the output roller 8.

A damping cutting device, characterized in that: Includes: Rack (1): A feeding conveyor belt (2), which is arranged on one side of the frame (1) and is used for feeding steel coils; A discharge guide plate (3) is arranged on the other side of the frame (1) away from the feed conveyor belt (2) and is used for discharging the steel coil; A clamping mechanism (5) is arranged on the frame (1) and is used to clamp and fix the steel coil; a pinching and cutting mechanism (4), which is arranged on the frame (1) between the clamping mechanism (5) and the discharge guide plate (3), and the pinching and cutting mechanism (4) has a cutter head (10) for cutting the steel coil; A guide roller (7) rotatably mounted on the frame (1) adjacent to the feed conveyor belt (2); a rotation drive unit (6) fixedly mounted on the frame (1), the rotation drive unit (6) having a drive shaft rotatable about a first axis, the drive shaft being connected to the guide roller (7) for driving the guide roller (7) to rotate; The clamping and cutting mechanism (4) includes a first telescopic drive unit (41), a mounting plate (42), a tensioning roller (46) and a supporting plate (47), wherein the first telescopic drive unit (41) is fixedly mounted on the frame (1), the mounting plate (42) is fixedly mounted on the driving end of the first telescopic drive unit (41), the cutting head (10) is provided on an edge of one side of the mounting plate (42) adjacent to the clamping mechanism (5), the tensioning roller (46) and the supporting plate (47) are both arranged on the mounting plate (42), and there is a gap between the tensioning roller (46) and the supporting plate (47) for the steel coil to pass through; The frame (1) includes two side plates (1a) arranged in parallel and at intervals, each of the side plates (1a) is provided with a slide groove (1b), the mounting plate (42) is provided with two sliders (43) which are slidably engaged with the slide groove (1b) in parallel and at intervals, and the tensioning roller (46) is rotatably arranged between the two sliders (43); A toothed plate (45) is vertically provided on each of the two side plates (1a), and a balancing gear (44) is coaxially provided at both ends of the tensioning roller (46), and the balancing gear (44) is meshedly connected with the toothed plate (45); The clamping mechanism (5) comprises a second telescopic drive unit (51), a first clamping plate (52) and a second clamping plate (53), wherein the second telescopic drive unit (51) and the second clamping plate (53) are both arranged on the frame (1), and a driving end of the second telescopic drive unit (51) is fixedly connected to the first clamping plate (52) for driving the first clamping plate (52) to move closer to or away from the second clamping plate (53); Among them, after the steel coil is cut, the first telescopic drive unit (41) continues to move downward. Since the cross section of the steel coil is against the vertical edge of the second clamping plate (53), there is no space for the cut steel coil to move toward the clamping mechanism (5). Relative sliding occurs between the roller surface of the tensioning roller (46) and the steel coil. When the first telescopic drive unit (41) contracts, the mounting plate (42) drives the tensioning roller (46) to move upward. Under the action of the balance gear (44) and the tooth plate (45), the tensioning roller (46) moves in the opposite direction. The roller surface of the tensioning roller (46) applies a reaction force to the steel coil, which helps the steel coil move toward the output roller (8) and promptly breaks the contact between the cross section of the steel coil and the side wall of the cutter head (10), so as to avoid the cutter head (10) driving the cross section of the steel coil to move upward and cause superposition or curling in the plane.

2. A damping cutting device according to claim 1, characterized in that: One end of a buffer spring (11) is connected to each of the two sliders (43), and the other end thereof is connected to the support plate (47). The buffer spring (11) has a tendency to move the support plate (47) away from the tensioning roller (46).

3. A damping cutting device according to claim 2, characterized in that: A relief portion (47a) is provided on the support plate (47) corresponding to the cutter head (10), and the relief portion (47a) is formed by an edge of the support plate (47) being inclined in a direction away from the cutter head (10).

4. The damping cutting device according to claim 1, characterized in that: A first high-temperature resistant felt (54) is provided on the clamping surface of the first clamping plate (52), and a second high-temperature resistant felt (55) is provided on the clamping surface of the second clamping plate (53).

5. A damping cutting device according to claim 4, characterized in that: The clamping surface of the first clamping plate (52) has a first anti-slip contour (52a), and the clamping surface of the second clamping plate (53) has a second anti-slip contour (53a).

6. The damping cutting device according to claim 1, characterized in that: It also includes a cooling liquid connector (9) for connecting to an external cooling liquid source, wherein the cooling liquid connector (9) is connected to a plurality of connecting pipes (91), wherein one of the connecting pipes (91) is connected to the inner cavity of the guide roller (7).
