Description

Technical Field

[0001] This invention relates to the technical field of automotive parts processing, and in particular to a guide groove bending machine. Background Technology

[0002] The guide channel is a structural component of the car's window and door lifting system and is a core part of the car's doors and windows. Currently, guide channels are typically long, strip-shaped metal components, which are machined and bent into a shape to fit the car's frame. Grooves are formed along the length of the guide channel; during processing, a bending machine is used to bend the guide channel into an arc shape.

[0003] In traditional bending machines, the guide groove is bent by applying external force during processing. For example, a vehicle window frame bending machine (publication number CN108526259A) installs the window frame into a mounting rail on the machine frame, and a fixing device secures the window frame to the mounting rail. The mounting rail includes a fixing part and a bending part. One end of the raw material is fixed to the fixing part, and the other end is fixed to the bending part. When the rotary cylinder of the drive device drives the drive shaft to move axially, it causes the bending part to rotate. During rotation, the inner wall of the curved bending part of the mounting rail gradually comes into contact with the window frame, thereby bending the window frame installed on the bending part, achieving the effect of bending the window frame.

[0004] In the existing technology, the side wall of the mounting track of the bending machine can only contact the outer wall of the guide groove. Since there is a groove in the guide groove, when the guide groove is bent under the external force of the bending machine, the inner wall of the guide groove at the bend will be twisted and wrinkled, which affects the processing quality of the guide groove. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a guide groove bending machine that can support the inner wall of the guide groove when it is bent, reduce the probability of the inner wall twisting and wrinkling during the bending process, and improve the processing quality of the guide groove.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: This invention provides a guide groove bending machine, the guide groove bending machine comprising: frame; The mold base includes a support platform and a bending mold strip. The support platform is fixedly mounted on the machine frame. The bending mold strip is mounted on the support platform and is used to bend and form the guide groove. A bending mechanism is provided on the frame and is used to clamp the end of the guide groove and drive the guide groove to bend to fit the bending mold strip. A filling mechanism includes a lifting assembly, a filling core, and a bending drive. The lifting assembly is disposed on the mold base, and the filling core is connected to the lifting assembly and can be vertically lifted and lowered under the drive of the lifting assembly. The filling core is disposed on the side of the bending mold strip facing the guide groove, and is used to insert into the groove of the guide groove and abut against the inner wall of the guide groove. The bending drive is connected to the filling core and is used to drive the filling core to bend into an arc that matches the guide groove.

[0007] Furthermore, the lifting assembly includes a lifting cylinder and a lifting seat, the lifting cylinder is disposed on the support platform, and the lifting seat is connected to the lifting cylinder; the filling core and the bending drive are connected to the lifting seat.

[0008] Furthermore, the filling core is arranged along the length direction of the guide groove, the first end of the filling core is connected to the lifting seat, the second end of the filling core is connected to the bending drive, and the bending drive can drive the filling core to bend into an arc shape around the first end.

[0009] Furthermore, the filling core includes a plurality of filling units connected in sequence, the lower part of the filling unit is inserted into the groove of the guide groove, and adjacent filling units are rotatably connected; among the plurality of filling units, the filling unit at the end away from the bending mechanism is connected to the lifting seat, and the filling unit at the end closer to the bending mechanism is connected to the bending drive.

[0010] Furthermore, the filling unit includes a filling plate and a connecting block, the filling plate being fixedly connected to the connecting block, and the filling plate being adapted to the groove of the guide groove; the ends of two adjacent connecting blocks that are close to each other are connected by a pivot.

[0011] Furthermore, the filling core also includes an elastic sheet, which is arranged parallel to the filling unit, and a plurality of the filling units are fixedly connected to the elastic sheet.

[0012] Furthermore, the bending drive includes a drive cylinder, the cylinder body of which is fixedly connected to the lifting seat, and the piston rod of which is connected to the filling core.

[0013] Furthermore, the filling mechanism also includes a limiting plate, which is fixedly connected to the lifting seat. The limiting plate has a limiting groove, and the filling core has a protruding limiting block. The limiting block is arranged parallel to the plane of the guide groove. The limiting block is inserted into the limiting groove and can swing in the limiting groove.

[0014] Furthermore, the bending mechanism includes a rotating component, a driving platform, and a clamping component. The rotating component is mounted on the frame, the driving platform is connected to the rotating component and can rotate under the drive of the rotating component, and the clamping component is disposed on the driving platform. The clamping component is used to clamp and fix the end of the guide groove.

[0015] Furthermore, the clamping assembly includes a vertical clamping cylinder and a horizontal clamping cylinder. The piston rod of the vertical clamping cylinder is connected to a vertical clamping block, and the piston rod of the horizontal clamping cylinder is connected to a horizontal clamping block. The drive platform is provided with a vertical clamping seat and a horizontal clamping seat. The vertical clamping block and the vertical clamping seat cooperate to vertically clamp the guide groove, and the horizontal clamping block and the horizontal clamping seat cooperate to horizontally clamp the guide groove.

[0016] In summary, the present invention has the following beneficial effects: 1. In the guide groove bending machine of the present invention, when performing guide groove bending operations, the guide groove is placed on the mold base. The end of the guide groove is clamped by the bending mechanism and driven to rotate around the bending mold strip, so that the guide groove is bent to fit the bending mold strip, and the guide groove is bent into an arc that matches the bending mold strip. The filling mechanism drives the filling core to move through the lifting component, so that the filling core can be inserted into the groove of the guide groove. The filling core abuts against the inner wall of the guide groove to support the guide groove from the inside. When the guide groove is bent, its interior is supported by the filling core and is not prone to wrinkles due to twisting, thus improving the processing quality of the guide groove. During the bending process of the guide groove, the bending drive also drives the filling core to bend, so that the filling core is bent into an arc that matches the guide groove, ensuring support for the inner wall of the guide groove, and at the same time avoiding the filling core from obstructing the bending of the guide groove, making the guide groove bending more stable and smooth.

[0017] 2. In this solution, both the bending drive and the filling core are connected to the lifting seat. When the lifting cylinder drives the lifting seat to rise and fall, it can drive the bending drive and the filling core to move vertically, so that the filling core can be vertically inserted into the groove of the guide slot. The bending drive and the filling core move synchronously to ensure the connection between the bending drive and the filling core.

[0018] 3. The filling core comprises multiple filling units connected in sequence, which are rotatably connected. The filling units at both ends are connected to a bending drive and a lifting seat, respectively, so that the bending drive can drive the multiple filling units to rotate to form an arc shape adapted to the guide groove. In this design, the multiple filling units are rotatably connected, facilitating the bending of the filling core into an arc shape under the action of the bending drive.

[0019] 4. Multiple filling units are fixedly connected to the elastic sheet, so that the multiple filling units are connected into a whole. When the bending drive drives the filling core to bend, the elastic sheet deforms and bends into an arc shape, so that the multiple filling cores connected to the elastic sheet bend into an arc shape and are not prone to irregular twisting.

[0020] 5. The bending drive unit drives the filling core to bend via a drive cylinder. The drive cylinder is mounted on the lifting seat and drives the filling core to bend via the extension and retraction of the piston rod. It has the advantages of simple structure and low cost.

[0021] 6. The lifting seat is fixedly connected to the limiting plate. The filling core is inserted into the limiting groove through the limiting block to limit the filling core in the vertical direction. This avoids the connection being unstable due to only one end of the filling core being connected to the lifting seat. As a result, the lifting seat can stably drive the filling core to rise and fall vertically, making the overall structure of the filling mechanism more reasonable. The limiting block is set parallel to the plane of the guide groove. When the filling core bends, the limiting groove leaves space for the limiting block to move. The limiting block can swing in the limiting groove to ensure that the filling core can bend. Attached Figure Description

[0035] The invention will now be further described with reference to the accompanying drawings.

[0036] This embodiment discloses a guide groove bending machine 1000, referring to... Figure 1 The guide groove bending machine 1000 includes a frame 100, a die base 200, a bending mechanism 300, and a filling mechanism 400. The die base 200 and the bending mechanism 300 are mounted on the frame 100. The die base 200 holds the guide groove 2000, and the bending mechanism 300 clamps the end of the guide groove 2000 and drives it to engage with the die base 200 to achieve bending. The filling mechanism 400 is located in the die base 200 and is inserted into the groove 2100 of the guide groove 2000 to support the guide groove 2000 from the inside.

[0037] Reference Figure 2In this embodiment, the mold base 200 includes a support platform 210 and a bending mold strip 220. The support platform 210 is a platform fixedly mounted on the frame 100. The bending mold strip 220 is an arc-shaped strip, which is fixedly mounted on the support platform 210 and is used to cooperate with the bending forming guide groove 2000.

[0038] Specifically, such as Figures 1 to 4 As shown, in this embodiment, the guide groove 2000 is a C-shaped arc component. Before bending, the guide groove 2000 is a straight strip. The guide groove 2000 is provided with a groove 2100 with the opening facing upwards. The support platform 210 is horizontally arranged, and two bending mold strips 220 are horizontally arranged on the support platform 210. The two bending mold strips 220 are mirror images and adjacent to each other, so that the two bending mold strips 220 are combined to form a C-shape. A bending mechanism 300 is provided on each side of the support platform 210. The guide groove 2000 is horizontally placed on the support platform 210, and the two bending mechanisms 300 respectively clamp the two ends of the guide groove 2000. The middle part of the guide groove 2000 abuts against the outer side of the opposite end of the two bending mold strips 220. When the two bending mechanisms 300 drive the two ends of the guide groove 2000 to move, the guide groove 2000 bends in the horizontal plane with the part that contacts the bending die 220 as the fulcrum, so that the other parts of the guide groove 2000 gradually move towards the outer side of the bending die 220 until the guide groove 2000 fits against the bending die 220, thereby bending the guide groove 2000 into a C-shape.

[0039] In other embodiments, the two guide grooves 2000 may be integrally formed (i.e., only one C-shaped guide groove 2000 may be provided). In other embodiments, the guide groove 2000 may be configured into other suitable shapes depending on the required processing shape. In other embodiments, a bending mechanism 300 may be provided only on one side of the support platform 210, with the bending mechanism 300 clamping one end of the guide groove 2000, and the other end or the middle of the guide groove 2000 fixed to the support platform 210.

[0040] In other embodiments, the support platform 210 may also be arranged vertically. Correspondingly, the bending template 220 is arranged vertically on the support platform 210, the guide groove 2000 is placed vertically on the support platform 210, and the bending mechanism 300 is arranged above or below the support platform 210 to drive the guide groove 2000 to bend in the vertical plane.

[0041] Reference Figure 4 and Figure 5In this embodiment, two filling mechanisms 400 are provided, corresponding to two bending mold strips 220, to fill the grooves 2100 of the guide grooves 2000 at the two bending mold strips 220. Specifically, the filling mechanism 400 includes a lifting assembly 410, a filling core 420, and a bending drive 430. The lifting assembly 410 is disposed on the mold base 200, and the filling core 420 is connected to the lifting assembly 410 and can be vertically lifted and lowered under the drive of the lifting assembly 410. The filling core 420 is disposed on the side of the bending mold strip 220 facing the guide groove 2000, and is used to insert into the groove 2100 of the guide groove 2000 and abut against the inner wall of the guide groove 2000. The bending drive 430 is connected to the filling core 420 and is used to drive the filling core 420 to bend into an arc adapted to the guide groove 2000.

[0042] In this embodiment, when the guide groove bending machine 1000 performs the bending operation of the guide groove 2000, the guide groove 2000 is placed on the mold base 200. The bending mechanism 300 clamps the end of the guide groove 2000 and pulls the guide groove 2000 to rotate around the bending mold strip 220, so that the guide groove 2000 bends to fit the bending mold strip 220, bending the guide groove 2000 into an arc that matches the bending mold strip 220. The filling mechanism 400 drives the filling core 420 to move through the lifting component 410, so that the filling core 420 is inserted into the groove 2100 of the guide groove 2000. By the filling core 420 abutting against the inner wall of the guide groove 2000, the guide groove 2000 is supported from the inside. When the guide groove 2000 is bent, its interior is supported by the filling core 420 and is not prone to wrinkles due to twisting, thus improving the processing quality of the guide groove 2000. During the bending process of the guide groove 2000, the bending drive 430 also drives the filling core 420 to bend, so that the filling core 420 bends into an arc that matches the guide groove 2000, ensuring support for the inner wall of the guide groove 2000, while avoiding the filling core 420 from hindering the bending of the guide groove 2000, making the guide groove 2000 more stable and smooth when bent.

[0043] Reference Figure 4 and Figure 5 In this embodiment, the lifting assembly 410 includes a lifting cylinder 411 and a lifting seat 412. The lifting cylinder 411 is disposed on the support platform 210, and the lifting seat 412 is connected to the lifting cylinder 411. The filling core 420 and the bending drive 430 are connected to the lifting seat 412. When the lifting cylinder 411 drives the lifting seat 412 to rise and fall, it can drive the bending drive 430 and the filling core 420 to move vertically, so that the filling core 420 can be vertically inserted into the groove 2100 of the guide groove 2000. The bending drive 430 and the filling core 420 move up and down synchronously to ensure the connection between the bending drive 430 and the filling core 420.

[0044] In this embodiment, the lifting cylinder 411 is placed upside down on the support platform 210, that is, the piston rod of the lifting cylinder 411 is connected to the support platform 210, and the cylinder body of the lifting cylinder 411 extends upward and is fixedly connected to the lifting seat 412. This arrangement can avoid interference between the cylinder body of the lifting cylinder 411 and the support platform 210. In other embodiments, the lifting cylinder 411 can also be arranged upright on the support platform 210, with the cylinder body fixed to the support platform 210 and the piston rod connected to the lifting seat 412.

[0045] In this embodiment, the cylinder body of the lifting cylinder 411 is fixedly connected to a guide seat 413, and the lifting seat 412 is fixedly connected to the guide seat 413. A guide post 414 is vertically arranged on the support platform 210, and the guide seat 413 is provided with a guide hole 415 that cooperates with the guide post 414. The guide seat 413 can move along the axial direction of the guide post 414. The guide is provided by the cooperation between the guide post 414 and the guide seat 413, so that the lifting cylinder 411 is set more stably on the support platform 210, and the lifting seat 412 is more stable when it rises and falls.

[0046] Reference Figure 4 and Figure 5 The filling core 420 is connected below the lifting seat 412. The filling core 420 is elongated and is arranged along the length of the guide groove 2000. The first end of the filling core 420 (i.e., the end of the filling core 420 near the middle of the guide groove 2000) is connected to the lifting seat 412, and the second end of the filling core 420 (i.e., the end of the filling core 420 near the end of the guide groove 2000) is connected to the bending drive 430. The bending drive 430 can drive the filling core 420 to bend into an arc shape around the first end.

[0047] After the filler core 420 is inserted into the groove 2100 of the guide groove 2000, when the guide groove 2000 is bent, the middle part of the guide groove 2000 abuts against the opposite ends of the two bending mold strips 220. The first end of the filler core 420 and the middle part of the guide groove 2000 will not move during bending. When the end of the guide groove 2000 is bent under the drive of the bending mechanism 300, the second end of the filling mechanism 400 bends with the guide groove 2000 under the drive of the bending drive member 430 to adapt to the guide groove 2000 and maintain abutment against the inner wall of the groove 2100 of the guide groove 2000.

[0048] Reference Figures 4 to 8 In this embodiment, the filling core 420 includes a plurality of filling units 421 connected in sequence. Adjacent filling units 421 are rotatably connected, so that the plurality of filling units 421 are connected to form a long chain-like structure. The lower part of the filling unit 421 is adapted to the groove 2100 of the guide groove 2000 so as to be inserted into the groove 2100 of the guide groove 2000.

[0049] In this embodiment, among the multiple filling units 421, the end of the filling unit 421 furthest from the bending mechanism 300 (i.e., the first end of the filling core 420) is connected to the lifting seat 412, and the end of the filling unit 421 closest to the bending mechanism 300 (i.e., the second end of the filling core 420) is connected to the bending drive member 430. This allows one end of the filling core 420 to be connected to the lifting seat 412 and the other end to be connected to the bending drive member 430, so that the bending drive member 430 can drive the multiple filling units 421 to rotate to form an arc shape that is compatible with the guide groove 2000.

[0050] In addition, in other embodiments, the filling core 420 may also adopt other suitable structures, such as the filling core 420 may include an elastic strip, which is inserted into the groove 2100 of the guide groove 2000, and the bending drive 430 may pull the end of the elastic strip to drive the elastic strip to bend into an arc shape that is compatible with the guide groove 2000.

[0051] In this embodiment, the filling unit 421 at the first end of the filling core 420 is rotatably connected to the lifting seat 412 via a pivot. This allows the filling unit 421 at the first end to rotate relative to the lifting seat 412 when the bending drive 430 drives the filling core 420 to bend, resulting in a smoother curve when the filling core 420 bends and better support for the inner wall of the guide groove 2000. Furthermore, in other embodiments, the filling unit 421 at the first end of the filling core 420 may also be fixedly connected to the lifting seat 412.

[0052] In this embodiment, the filling unit 421 includes a filling plate 4211 and a connecting block 4212. The filling plate 4211 is fixedly connected to the connecting block 4212, and the lower part of the filling plate 4211 protrudes from the lower part of the connecting block 4212. The lower part of the filling plate 4211 is adapted to the groove 2100 of the guide groove 2000 to insert into the groove 2100 of the guide groove 2000 and support the guide groove 2000 from the inside. Thus, the filling unit 421 only requires the lower part of the filling plate 4211 to be inserted into the groove 2100 of the guide groove 2000, while the connecting block 4212 is located above the guide groove 2000, making it less likely to interfere with the bending die 220.

[0053] In this embodiment, the ends of two adjacent connecting blocks 4212 that are close to each other are connected by a pivot 4215 to achieve a rotatable connection between adjacent filling units 421. Specifically, in the two adjacent connecting blocks 4212, one connecting block 4212 has a connecting protrusion 4213 at its end, and the other connecting block 4212 has a connecting groove 4214 that mates with the connecting protrusion 4213 at its end. Both the connecting protrusion 4213 and the connecting groove 4214 have through holes that are aligned with each other. The pivot 4215 passes through the through holes of the connecting protrusion 4213 and the connecting groove 4214 to rotatably connect the two connecting blocks 4212.

[0054] The filling core 420 also includes an elastic sheet 422, which is a long, elastic sheet-like metal piece. The elastic sheet 422 is arranged perpendicular to the horizontal plane, and its length direction is parallel to the filling unit 421. Multiple filling units 421 are fixedly connected to the elastic sheet 422.

[0055] In this embodiment, multiple filling units 421 are connected into a whole by elastic sheet 422. When bending drive 430 drives filling core 420 to bend, elastic sheet 422 deforms and bends into an arc shape, so that multiple filling cores 420 connected to elastic sheet 422 bend into an arc shape. Irregular bending between the connecting blocks 4212 of multiple filling units 421 is less likely to occur, which would affect the support of filling core 420 on the inner wall of guide groove 2000.

[0056] In this embodiment, the elastic sheet 422, the connecting block 4212, and the filling plate 4211 are connected by bolts, with the bolts passing through the elastic sheet 422, the connecting block 4212, and the filling plate 4211 to fix them together as a whole. In other embodiments, the elastic sheet 422, the connecting block 4212, and the filling plate 4211 can also be fixed using other suitable methods.

[0057] In this embodiment, the elastic sheet 422 is disposed on the rear side of the connecting block 4212, and the filling plate 4211 is disposed on the front side of the connecting block 4212. Furthermore, in other embodiments, the elastic sheet 422 may also be disposed on the front side of the connecting block 4212; in other embodiments, the filling plate 4211 may also be disposed on the rear side of the connecting block 4212. In other embodiments, the elastic sheet 422 may also be disposed on both the front and rear sides of the connecting block 4212.

[0058] Reference Figures 4 to 6 In this embodiment, the bending drive 430 includes a drive cylinder, which is horizontally mounted on the lifting seat 412. The cylinder body of the drive cylinder is fixedly connected to the lifting seat 412, and the piston rod of the drive cylinder extends forward and is connected to the second end of the filling core 420 via a connecting rod. The bending drive 430 drives the filling core 420 to bend via the drive cylinder. The drive cylinder extends and retracts via the piston rod, causing the filling core 420 to bend. This method has the advantages of simple structure and low cost. In addition, in other embodiments, the bending drive 430 may also adopt an electric actuator, a gear mechanism, or other drive mechanisms capable of driving the second end of the filling core 420 to bend relative to the first end.

[0059] Reference Figures 4 to 8In this embodiment, a limiting plate 416 is also fixedly installed below the lifting seat 412, and the limiting plate 416 is located on the front side of the filling core 420. The limiting plate 416 has a limiting groove 417 that extends through the limiting plate 416 in the front-rear direction. The filling core 420 has a protruding limiting block 423. Specifically, the limiting block 423 is fixedly connected to the upper part of the front side of the filling plate 4211 and extends horizontally forward. The limiting block 423 is arranged parallel to the curved plane of the guide groove 2000, and the limiting block 423 is inserted into the limiting groove 417 and can swing in the limiting groove 417. The filling core 420 is inserted into the limiting groove 417 via a limiting block 423 to vertically limit the filling core 420, preventing unstable connection caused by only one end of the filling core 420 being connected to the lifting seat 412. This allows the lifting seat 412 to stably drive the filling core 420 to rise and fall vertically, making the overall structure of the filling mechanism 400 more reasonable. When the filling core 420 bends, the limiting groove 417 provides space for the limiting block 423 to move, allowing the limiting block 423 to swing within the limiting groove 417, ensuring that the filling core 420 can bend.

[0060] In this embodiment, a limiting block 423 is fixedly provided on the upper front side of each filling plate 4211. Correspondingly, multiple limiting grooves 417 are provided on the limiting plate 416. The limiting grooves 417 are distributed along the length direction of the limiting plate 416, and the limiting blocks 423 are inserted into the limiting grooves 417 one by one.

[0061] In this process, the lengths of the multiple limiting blocks 423 gradually increase along the direction from the first end to the second end of the filling core 420. When the filling core 420 is bent, the distance between the filling core 420 and the limiting plate 416 gradually increases from the first end to the second end, and the lengths of the limiting blocks 423 also gradually increase, so as to ensure that the limiting blocks 423 at different positions are always inserted into the limiting grooves 417.

[0062] In this embodiment, the limiting block 423 at the second end of the filling core 420 is rotatably connected to the piston rod of the bending drive 430 via a connecting rod, so that when the bending drive 430 extends or retracts, it can drive the second end of the filling core 420 to rotate and bend relative to the first end. Furthermore, in other embodiments, the piston rod of the bending drive 430 may also be directly connected to the connecting block 4212, the filling plate 4211, or other parts at the second end of the filling core 420.

[0063] Reference Figure 9In this embodiment, the bending mechanism 300 includes a rotating component 310, a driving platform 320, and a clamping component 330. The rotating component 310 is mounted on the frame 100. The driving platform 320 is connected to the rotating component 310 and can rotate under the drive of the rotating component 310. The clamping component 330 is disposed on the driving platform 320 and is used to clamp the end of the fixed guide groove 2000. During the bending operation of the guide groove 2000, the clamping component 330 clamps the end of the guide groove 2000. The rotating component 310 drives the driving platform 320 and the clamping component 330 to rotate, causing the guide groove 2000 to rotate around the bending die 220, so as to cooperate with the bending die 220 to bend the guide groove 2000.

[0064] Reference Figure 10 In this embodiment, the rotating assembly 310 includes a rotating motor 311, a gearbox 312, a base 313, and an output shaft 314. The base 313 is fixed to the frame 100. The motor shaft of the rotating motor 311 is connected to the gearbox 312, and the gearbox 312 is connected to the output shaft 314. The output shaft 314 is rotatably mounted on the base 313 and connected to the drive platform 320. The rotation output by the rotating motor 311 is adjusted by the gearbox 312 and then output to the output shaft 314, driving the output shaft 314 to rotate the drive platform 320 relative to the base 313. Alternatively, in other embodiments, the rotating assembly 310 may also employ a rotary cylinder or other suitable rotary drive components.

[0065] Reference Figure 11 In this embodiment, the drive platform 320 is a cuboid plate-shaped component. A slide rail 321 and a linear drive assembly 322 are fixedly mounted on the drive platform 320. The slide rail 321 is horizontally mounted on the drive platform 320. A slider 323 that cooperates with the slide rail 321 is provided at the bottom of the clamping assembly 330. The linear drive assembly 322 is connected to the clamping assembly 330. Thus, the linear drive assembly 322 can drive the clamping assembly 330 to move linearly. Before bending the guide groove 2000, the clamping assembly 330 clamps the guide groove 2000, and the linear drive assembly 322 drives the clamping assembly 330 to move linearly to stretch the guide groove 2000, so that the guide groove 2000 reaches its yield limit. This makes the bending deformation of the guide groove 2000 during bending plastic deformation, making it less prone to springback after bending and ensuring the bending processing quality of the guide groove 2000.

[0066] In this embodiment, the linear drive assembly 322 is specifically a motor lead screw mechanism, which includes a drive motor, a lead screw, and a lead nut. The drive motor is fixedly mounted on the drive platform 320, the lead screw is connected to the motor shaft of the drive motor and is rotatably and horizontally mounted on the drive platform 320, and the lead nut is threaded into the lead screw and fixedly connected to the clamping assembly 330. In other embodiments, the linear drive assembly 322 may also be a hydraulic cylinder, a pneumatic cylinder, a gear rack, a transmission belt, or other suitable linear drive assembly 322.

[0067] Reference Figure 11 and Figure 12 In this embodiment, a clamping support 324 is provided on the drive stage 320, a slider 323 is installed at the bottom of the clamping support 324, and a clamping assembly 330 is provided on the clamping support 324.

[0068] The clamping assembly 330 includes a vertical clamping cylinder 331 and a horizontal clamping cylinder 332. The cylinder body of the vertical clamping cylinder 331 is vertically fixed on the clamping support 324, and its piston rod is downwardly positioned and connected to a vertical clamping block 333. The cylinder body of the horizontal clamping cylinder 332 is horizontally fixed on the clamping support 324, and is located below and to one side of the vertical clamping cylinder 331. The piston rod of the horizontal clamping cylinder 332 extends horizontally and is connected to a horizontal clamping block 334.

[0069] The clamping support 324 is provided with a vertical clamping seat 335 and a horizontal clamping seat 336. The vertical clamping seat 335 is located below the vertical clamping block 333, and the vertical clamping block 333 and the vertical clamping seat 335 cooperate to clamp the vertical guide groove 2000. The horizontal clamping seat 336 is located on the side of the horizontal clamping block 334 away from the horizontal clamping cylinder 332, and the horizontal clamping seat 336 and the horizontal clamping block 334 are located on opposite sides of the vertical clamping seat 335; the horizontal clamping block 334 and the horizontal clamping seat 336 cooperate to clamp the horizontal guide groove 2000.

[0070] The lower end of the vertical clamping block 333 protrudes downward to form a clamping part 337 that fits into the groove 2100 of the guide groove 2000. When the vertical clamping cylinder 331 drives the vertical clamping block 333 to move downward, the clamping part 337 is inserted into the groove 2100 of the guide groove 2000, and the guide groove 2000 is clamped between the clamping part 337 and the vertical clamping seat 335. Subsequently, the horizontal clamping cylinder 332 drives the horizontal clamping block 334 to move horizontally. The horizontal clamping block 334 and the horizontal clamping seat 336 abut against the outside of the guide groove 2000, and the guide groove 2000 is clamped between the horizontal clamping block 334 and the horizontal clamping seat 336, thereby achieving the clamping and fixing of the end of the guide groove 2000. When the horizontal clamping block 334 abuts against the outside of the guide groove 2000, since the clamping part 337 is inserted in the groove 2100 of the guide groove 2000, the horizontal clamping block 334 is less likely to cause deformation of the guide groove 2000 when it applies clamping force to the guide groove 2000, which helps to ensure the finished product quality of the guide groove 2000.

[0071] The above are merely preferred embodiments of the present invention. Therefore, all equivalent changes or modifications made in accordance with the structure, features and principles of the present invention patent application are included within the scope of the present invention patent application.
