Description

Technical Field

[0001] This utility model belongs to the field of bending technology, and specifically relates to a bending system. Background Technology

[0002] A bending machine is a metal processing equipment that can bend thin plates. It features high precision, high efficiency, and strong adaptability, and is widely used in industries such as machinery manufacturing, construction, electronics, and automobiles.

[0003] During the bending process, the workpiece to be bent needs to be lifted by a hoisting device. The hoisting device includes an electric hoist and a rope at the output end of the electric hoist. The other end of the rope is connected to the workpiece to be bent. The electric hoist drives the rope to move, thereby hoisting the workpiece to be bent onto the bending die of the bending machine, so that the bending machine can bend the workpiece.

[0004] However, when the rope carries the workpiece to the bending die of the bending machine, the lifting device and the bending machine are located at different positions in the horizontal direction. Therefore, an angle is generated between the rope and the bending direction of the bending machine. This causes the direction of the tension force of the lifting device on the workpiece to deviate from the bending direction of the bending machine, making the workpiece prone to deviation during the bending process and affecting the bending accuracy of the workpiece. Utility Model Content

[0005] The purpose of this invention is to provide a bending system that improves the bending accuracy of workpieces.

[0006] To achieve the above objectives, the present invention provides a bending system comprising: a bending mechanism for bending a workpiece by applying a vertically downward pressure to the workpiece; a lifting mechanism including a workpiece sling for connection to the workpiece and configured to place the workpiece on the bending mechanism; and a guiding mechanism, wherein the workpiece sling is at least partially guided by the guiding mechanism to apply a vertically upward tension to the workpiece placed on the bending mechanism when the workpiece is bent by the bending mechanism.

[0007] In some embodiments, the lifting mechanism further includes a drive member configured to wind up and release the workpiece sling to apply tension to the workpiece via the workpiece sling.

[0008] In some embodiments, the lifting mechanism further includes a clamping member disposed at the end of the workpiece sling away from the drive member and used to clamp the workpiece.

[0009] In some embodiments, the guiding mechanism includes: a bracket disposed below the hoisting mechanism; and a plurality of guide members mounted on the bracket, wherein the workpiece sling extends sequentially through the guide members, thereby causing the workpiece sling to apply tension to the workpiece in a vertical direction.

[0010] In some embodiments, the support includes: a lower crossbeam mounted on the bending mechanism and sliding horizontally along the bending mechanism along a length direction perpendicular to the lower crossbeam; an upper crossbeam spaced parallel to the lower crossbeam; and a support beam for connecting the upper crossbeam and the lower crossbeam.

[0011] In some embodiments, at least two guide members are provided, namely: a first guide member, which is disposed on the lower crossbeam and located below the hoisting mechanism to change the extension direction of the workpiece sling; and a second guide member, which is disposed on the side of the upper crossbeam near the bending position of the bending mechanism, wherein the workpiece sling passes through the first guide member and the second guide member in sequence and is connected to the workpiece.

[0012] In some embodiments, the guiding mechanism further includes a third guide member disposed on the upper crossbeam and on the same horizontal plane as the second guide member, the third guide member being disposed between the first guide member and the second guide member along the length direction of the upper crossbeam.

[0013] In some embodiments, the upper crossbeam is slidably disposed on the support beam along the length direction of the upper crossbeam.

[0014] In some embodiments, the guide is a guide wheel rotatably mounted on the bracket.

[0015] In some embodiments, the bending mechanism includes: a main body, on which the lifting mechanism and the guiding mechanism are respectively mounted; a driver, which is mounted on the main body; an upper pressure plate, which is connected to the output end of the driver; and a lower die, which is mounted below the upper pressure plate and is used to place a workpiece, wherein the driver is capable of driving the upper pressure plate to move vertically to apply a vertically downward pressure to the workpiece.

[0016] Through the above technical solutions, the bending mechanism can apply vertical downward pressure to the workpiece, thereby bending the workpiece according to a preset angle or shape to meet the bending requirements of the workpiece; the hoisting mechanism can move the workpiece to a fixed position on the bending mechanism to ensure the precise positioning and placement of the workpiece; the guiding mechanism changes the movement path of the workpiece sling, so that the workpiece sling can move along a predetermined path, ensuring that the direction of the tension applied by the workpiece sling to the workpiece is exactly opposite to the direction of the pressure applied by the bending mechanism to the workpiece, ensuring that the workpiece is under stable force during the bending process, avoiding the workpiece from shifting or deforming during the bending process, and improving the bending accuracy of the workpiece.

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] It should be noted that, in this utility model, unless otherwise stated, the vertical direction generally refers to... Figure 1 The direction indicated by the middle arrow, using directional terms such as "up" or "down," usually refers to along... Figure 1 The vertical direction indicated by the middle arrow represents the relative positions of "up" and "down".

[0027] See Figure 1 This utility model provides a bending system, including a bending mechanism 1, a lifting mechanism 2, and a guiding mechanism 3. The bending mechanism 1 bends the workpiece 4 by applying a vertically downward pressure to the workpiece 4. The lifting mechanism 2 includes a workpiece sling 21 for connecting to the workpiece 4 and is configured to place the workpiece 4 on the bending mechanism 1. The workpiece sling 21 is at least partially guided by the guiding mechanism 3 so that when the workpiece 4 is bent by the bending mechanism 1, the workpiece sling 21 applies a vertically upward tension to the workpiece 4 placed on the bending mechanism 1. The guide mechanism 3 changes the movement path of the workpiece sling 21 of the hoisting mechanism 2, allowing the workpiece sling 21 to move along the predetermined path of the guide mechanism 3. This enables the hoisting mechanism 2 to accurately place the workpiece 4 connected to the workpiece sling 21 at the bending position of the bending mechanism 1, so that the bending mechanism 1 can apply vertical downward pressure to the workpiece 4 according to a preset angle or shape to achieve bending of the workpiece 4. During the bending process of the bending mechanism 1, the workpiece sling 21 can apply a vertical upward tension to the workpiece 4 in the opposite direction to the pressure applied by the bending mechanism 1, thereby ensuring that the workpiece 4 is balanced and stable during the bending process, avoiding oblique tension on the workpiece 4 during the bending process, preventing the workpiece 4 from shifting or deforming during the bending process, and improving the bending accuracy of the workpiece 4.

[0028] In some embodiments, the bending system of this invention is particularly suitable for bending longer and heavier workpieces 4.

[0029] In some embodiments, the lifting mechanism 2 further includes a drive member 22, which is configured to retract and release the workpiece sling 21 to apply tension to the workpiece 4 via the workpiece sling 21. The workpiece sling 21 is used to transmit the force of the drive member 22, thereby enabling the vertical movement of the workpiece 4 to achieve bending at different positions of the workpiece 4 and meet the bending requirements of the workpiece 4.

[0030] In some embodiments, the workpiece sling 21 can be a braided steel wire rope.

[0031] Those skilled in the art will understand that this utility model is not limited to the above-mentioned braided steel wire rope, but may also include other structural forms such as chains that can connect workpieces 4, all of which should fall within the protection scope of this utility model.

[0032] In some implementations, the drive unit 22 can be an electric hoist.

[0033] Those skilled in the art will understand that this utility model is not limited to the electric hoist described above, but may also include other structural forms such as motors and cylinders that can achieve the stretching of workpiece sling 21, all of which should fall within the protection scope of this utility model.

[0034] In some implementations, the electric hoist is connected to the workpiece sling 21 via a shackle.

[0035] In some implementations, see Figure 2 The lifting mechanism 2 also includes a clamping member 23, which is located at the end of the workpiece sling 21 away from the drive member 22 and is used to clamp the workpiece 4. The clamping member 23 can firmly clamp the workpiece 4, prevent the workpiece 4 from moving during bending and clamping, and ensure the stability of the workpiece 4.

[0036] In some embodiments, the clamping member 23 can be a vertical steel plate lifting clamp, which is a lifting tool used for vertically lifting steel plate items. It can firmly clamp the workpiece 4, is easy to operate, and has high work efficiency.

[0037] Those skilled in the art will understand that this utility model is not limited to the above-mentioned vertical steel plate lifting clamp, but may also include other structural forms that can clamp workpiece 4, all of which should fall within the protection scope of this utility model.

[0038] In some implementations, see Figure 1 and Figure 2 The guiding mechanism 3 includes a bracket 31 and several guide members. The bracket 31 is located below the hoisting mechanism 2, and the guide members are mounted on the bracket 31. The workpiece sling 21 extends sequentially through the guide members, thereby applying a tension force to the workpiece 4 in the vertical direction. The bracket 31 supports and fixes the guide members; the guide members guide the direction of the workpiece sling 21, enabling it to move stably along a predetermined path and thus applying a tension force to the workpiece 4 in the vertical direction.

[0039] In some embodiments, the guide is a guide wheel rotatably mounted on the bracket 31.

[0040] Those skilled in the art will understand that this utility model is not limited to the guide wheel described above, and may also include other structural forms such as pulleys and rollers that can guide the workpiece sling 21, all of which should fall within the protection scope of this utility model.

[0041] In some embodiments, the support 31 includes a lower crossbeam 311, an upper crossbeam 312, and a support beam 313. The lower crossbeam 311 is mounted on the bending mechanism 1 and slides horizontally along the length direction perpendicular to the lower crossbeam 311. The upper crossbeam 312 is arranged parallel to and spaced apart from the lower crossbeam 311. The support beam 313 connects the upper crossbeam 312 and the lower crossbeam 311. The arrangement of the lower crossbeam 311, the upper crossbeam 312, and the support beam 313 constitutes the stable structure of the support 31. The horizontal sliding of the lower crossbeam 311 allows the support 31 to move along the length direction perpendicular to the lower crossbeam 311, thereby enabling the support 31 to move accurately to the vicinity of the bending position of the bending mechanism 1, ensuring that the guide mechanism 3 on the support 31 can guide the workpiece 4 on the workpiece sling 21 to the bending position of the bending mechanism 1.

[0042] In some embodiments, the bending mechanism 1 is provided with a slide rail perpendicular to the length direction of the lower crossbeam 311, and a slider is provided at the bottom of the lower crossbeam 311, the slider being slidably mounted on the slide rail.

[0043] Those skilled in the art will understand that this utility model is not limited to the above-mentioned combination of slider and slide rail, but may also include other structural forms such as screw and elongated hole that can realize the horizontal sliding of the lower crossbeam 311, all of which should be within the protection scope of this utility model.

[0044] In some embodiments, the lower crossbeam 311 is also provided with a locking element, which is used to lock the relative position of the lower crossbeam 311 and the bending mechanism 1. When the lower crossbeam 311 moves along the slide rail to the vicinity of the bending position, the locking element locks the lower crossbeam 311 onto the bending mechanism 1, preventing the lower crossbeam 311 from moving and ensuring the stability of the workpiece lifting cable 21.

[0045] In some embodiments, the locking element may be a bolt. The bolt passes through the lower crossbeam 311 and abuts against the slide rail.

[0046] Those skilled in the art will understand that this utility model is not limited to the bolts mentioned above, but may also include other structural forms such as screws, nuts and elongated holes that can lock the lower crossbeam 311, all of which should fall within the protection scope of this utility model.

[0047] In some embodiments, multiple support beams 313 may be provided, and the multiple support beams 313 are spaced apart along the length direction of the upper crossbeam 312 to ensure the stability and robustness of the structure of the bracket 31.

[0048] In some implementations, see Figure 2 At least two guide members are provided, namely a first guide member 32 and a second guide member 33. The first guide member 32 is located on the lower crossbeam 311 and below the lifting mechanism 2 to change the extension direction of the workpiece sling 21. The second guide member 33 is located on the side of the upper crossbeam 312 near the bending position of the bending mechanism 1. The workpiece sling 21 passes through the first guide member 32 and the second guide member 33 in sequence and connects to the workpiece 4. The first guide member 32 can change the workpiece sling 21, which extends vertically away from the drive member 22, to extend obliquely upwards towards the bending position. The second guide member 33 can change the oblique upward extension direction of the workpiece sling 21 to a vertical direction. Through the guidance of the workpiece sling 21 by the first guide member 32 and the second guide member 33, it is ensured that the tension applied by the lifting mechanism 2 to the workpiece 4 is opposite to the pressure applied by the bending mechanism 1 to the workpiece 4, thereby ensuring that the workpiece 4 is subjected to balanced forces and is stable during the bending process, and avoiding the workpiece 4 being subjected to oblique tension during the bending process.

[0049] In some embodiments, the first guide member 32 is a first guide wheel, which is rotatably mounted on the lower crossbeam 311.

[0050] In the above, there are several ways in which the first guide wheel can be rotatably mounted on the lower crossbeam 311, for example... Figure 2 In the embodiment shown, two fixing plates are fixedly installed on the lower crossbeam 311, and a rotating shaft is fixedly installed between the two fixing plates. The guide wheel is rotatably mounted on the rotating shaft.

[0051] In some embodiments, the second guide member 33 is a second guide wheel, which is rotatably mounted on the upper crossbeam 312.

[0052] In the above, there are several ways in which the second guide wheel can be rotated on the upper crossbeam 312, for example... Figure 3 and Figure 4 In the embodiment shown, the upper crossbeam 312 includes a base plate 3121 and two side plates 3122 spaced apart on both sides of the base plate 3121. The base plate 3121 is connected to the support beam 313. A rotating shaft 3123 is fixedly arranged between the two side plates 3122. A second guide wheel is rotatably arranged on the rotating shaft 3123 and along the axial direction of the rotating shaft 3123. Two limiting members 3124 are spaced apart on both sides of the second guide wheel to prevent the second guide wheel from moving along the axial direction of the rotating shaft 3123.

[0053] In some embodiments, the limiting member 3124 may be a sleeve that is fixedly sleeved outside the rotating shaft 3123.

[0054] In some embodiments, the second guide wheel is further provided with an annular groove 36 in the circumferential direction, which is used to place the workpiece sling 21. The annular groove 36 can effectively ensure that the workpiece sling 21 moves along a predetermined path and avoid the workpiece sling 21 shifting its position during movement.

[0055] Those skilled in the art will understand that this utility model is not limited to the aforementioned annular groove 36, but can also be any other structural form that can realize the placement of the workpiece sling 21 and should also fall within the protection scope of this utility model.

[0056] In some implementations, for example Figure 4 In the embodiment shown, the rotating shaft 3123 includes a rotating shaft body and an end cap. One end of the rotating shaft body is provided with a protrusion and is integrally formed with the rotating shaft body. Through holes are provided on both side plates. The diameter of the through holes is larger than the outer diameter of the rotating shaft body and smaller than the outer diameter of the protrusion and the end cap. The rotating shaft body passes through the through holes of the two side plates and is detachably connected to the end cap to realize the installation of the rotating shaft 3123 and the upper crossbeam 312.

[0057] In the above, the detachable connection between the shaft body and the end cover can take several forms, for example... Figure 4 In the embodiment shown, the end cap is provided with an opening, and the shaft body is provided with a threaded hole along the axial direction. The bolt passes through the opening and is threadedly connected to the threaded hole of the shaft body, thereby realizing the fixed connection between the shaft body and the end cap.

[0058] In some implementations, see Figure 2 The guiding mechanism 3 also includes a third guide member 34, which is disposed on the upper crossbeam 312 and on the same horizontal plane as the second guide member 33. The third guide member 34 is disposed between the first guide member 32 and the second guide member 33 along the length direction of the upper crossbeam 312. The third guide member 34 is used to guide the extension direction of the workpiece sling 21 to ensure the stability of the workpiece sling 21 during movement.

[0059] In some embodiments, in order to further guide the extension direction of the workpiece sling 21 and ensure the stability of the workpiece sling 21 during movement, the guiding mechanism 3 further includes a fourth guide member 35. The fourth guide member 35 is disposed on the upper crossbeam 312 and is disposed between the second guide member 33 and the third guide member 34 along the length direction of the upper crossbeam 312.

[0060] In some embodiments, the upper crossbeam 312 is slidably disposed on the support beam 313 along the length direction of the upper crossbeam 312. By adjusting the relative position of the upper crossbeam 312 along the length direction, it is ensured that the workpiece 4 connected by the workpiece sling 21 can be accurately placed at the bending position of the bending mechanism 1, avoiding oblique tension on the workpiece 4; and it can adapt to the bending of workpieces 4 of different shapes and sizes.

[0061] In the above, the upper crossbeam 312 can be slidably mounted on the support beam 313 in several ways, for example... Figure 4 In the embodiment shown, a slide rail is provided at the bottom of the upper crossbeam 312 along the length direction, and a slider is provided above the support beam 313. The slider is slidably mounted on the slide rail, thereby realizing the sliding arrangement of the upper crossbeam 312 and the support beam 313.

[0062] In some embodiments, the bracket also includes bolts, which are disposed on the upper crossbeam 312. The support beam 313 has an elongated hole along the length of the upper crossbeam 312. The bolts pass through the elongated hole and are threadedly connected to the nut, thereby fixing the upper crossbeam 312 and the support beam 313 together and preventing the upper crossbeam 312 from moving during the guiding process.

[0063] In some embodiments, spring washers and flat washers are also provided at the connection between the bolt and the upper crossbeam 312 to ensure the stability and safety of the connection between the bolt and the upper crossbeam 312 and to prevent the bolt from loosening.

[0064] In some implementations, see Figure 1 The bending mechanism 1 includes a main body 11, a driver 12, an upper pressure plate 13, and a lower die 14. A lifting mechanism 2 and a guiding mechanism 3 are respectively mounted on the main body 11. The driver 12 is mounted on the main body 11, and the upper pressure plate 13 is connected to the output end of the driver 12. The lower die 14 is mounted below the upper pressure plate 13 and is used to place the workpiece 4. The driver 12 can drive the upper pressure plate 13 to move vertically to apply vertically downward pressure to the workpiece 4. By mounting the lifting mechanism 2 and the guiding mechanism 3 on the main body 11, the bending mechanism 1, the lifting mechanism 2, and the guiding mechanism 3 are connected. When the lifting mechanism 2 and the guiding mechanism 3 move the workpiece 4 onto the lower die 14, the driver 12 drives the upper pressure plate 13 to move vertically downward, applying vertically downward pressure to the workpiece 4, thereby bending the workpiece 4 on the lower die 14 and ensuring the accuracy and efficiency of bending the workpiece 4.

[0065] In some implementations, see Figure 1 The main body 11 includes an upper body 11 and a lower body 11, with an accommodating space between the upper body 11 and the lower body 11. The hoisting mechanism 2 is installed on the upper body 11, and the guiding mechanism 3 is installed on the lower body 11 and can move within the accommodating space.

[0066] The specific structure of the bending mechanism 1 that realizes workpiece bending is well known to those skilled in the art and is not a core improvement of this utility model, so it will not be described in detail here.

[0067] like Figure 1As shown, the workpiece sling 21 is connected to the drive component 22 of the hoisting mechanism 2. The workpiece sling 21 changes its extension direction after passing through the first guide component 32, and then passes through the third guide component 34, the fourth guide component 35 and the second guide component 33 to reach the upper mold 14. The drive component 22 is activated and jogged to rewind the workpiece sling 21. The workpiece 4 is subjected to a vertical upward tension, thereby placing the workpiece 4 in the bending position, ensuring that the workpiece 4 is not subjected to oblique tension and that there is no excessive displacement in the length direction of the upper crossbeam 312, eliminating the safety hazard caused by oblique tension. The upper pressure plate 13 of the bending mechanism 1 moves downward in the vertical direction to the position where it presses against the workpiece 4. The clamping component 23 is removed to prevent the clamping component 23 from interfering with the bending mechanism 1 during the bending process of the workpiece 4 and causing damage to the workpiece 4. The drive component 22 is activated to retract the workpiece sling 21 and move the clamping component 23 upward to a certain height. The driver 12 is activated to make the upper pressure plate 13 continue to move downward, bending the workpiece 4 to a suitable angle.

[0068] For longer workpieces 4, multiple sets of lifting mechanisms 2 and guiding mechanisms 3 can be set up to place the workpieces 4.
