Description

Technical Field

[0001] This invention relates to the field of metal sheet processing technology, and more specifically, to a bending processing apparatus for metal sheets. Background Technology

[0002] In the metal sheet processing industry, metal sheet bending is a fundamental and crucial process that is widely used in many fields such as automobile manufacturing, construction, home appliances, and aerospace; especially for bending specific shaped sheets such as U-shaped sheets.

[0003] According to the metal plate bending processing device disclosed in CN119158944A, the upper end face of the upper support plate is flush with the upper end face of the lower mold, the upper support plate has a notch that matches the size of the lower mold, the support frame is provided with a punching head that cooperates with the lower mold, and a short shaft is provided on one side of the support frame.

[0004] The aforementioned patents still have shortcomings in practical use:

[0005] When bending a metal sheet using the combination of the stamping head and the lower die, the lack of a device to clamp and position the metal sheet placed on the upper support plate will cause the metal sheet to shift during bending, resulting in processing deviations. At the same time, during the bending process, debris falling from the metal sheet will accumulate on the worktable, which will affect the bending process of the metal sheet.

[0006] Based on this, the present invention discloses a bending processing device for metal plates. Summary of the Invention

[0007] To address the problems mentioned in the background art, such as the lack of a clamping and positioning device for the metal plate placed on the upper support plate, which leads to metal plate misalignment and processing deviation during bending, and the accumulation of debris falling from the metal plate on the worktable during bending, thus affecting the bending process, this invention provides a metal plate bending device, comprising:

[0008] Because of the lack of a device for clamping and positioning the metal plate placed on the upper support plate, the metal plate will shift during bending, resulting in processing deviations. Simultaneously, during bending, debris falling from the metal plate will accumulate on the worktable, further affecting the bending process. This technical solution addresses this by using a motor to drive the rotation of the threaded rod two. Through the belt connection between pulley one and pulley two, the rotation of the threaded rod one causes the threaded sleeves one at the bottom of the two clamping and positioning plates to move in opposite directions along the two threads on the threaded rod one, thus positioning and clamping the metal plate on the support plate, keeping the metal plate in the center of the mold body. Simultaneously, the threaded sleeves two located at the two threads of the threaded rod two move in opposite directions along the threaded rod two, allowing the cleaning plate to clean the debris from the worktable.

[0009] As a further improvement to this technical solution, a worktable is included. A mold device is mounted at the top of the worktable. A stamping device for bending metal plates in cooperation with the mold device is fixedly installed at the top of the worktable.

The cleaning device includes a second drive assembly for rotation within the worktable. A cleaning assembly for cleaning the worktable is threadedly connected to the shaft of the second drive assembly.

[0010] As a further improvement to this technical solution, a support plate for placing metal plates is fixedly installed on the top of the workbench, and a sliding groove for moving the cleaning components is provided on the top of the workbench.

A hydraulic rod for vertical movement is fixedly installed on the frame of the support frame. A stamping head for bending metal plates in cooperation with the mold assembly is fixedly installed at the bottom end of the hydraulic rod.

[0012] As a further improvement to this technical solution, the mold assembly includes a mold body fixedly installed on the top of the workbench, and the mold body is located inside the support plate. The mold body has a placement slot for moving the ejector component.

[0013] As a further improvement to this technical solution, the pop-out component includes four fixing rods fixedly installed inside the mold body, and springs are fitted on the rods of the fixing rods.

[0014] As a further improvement to this technical solution, a limiting plate for moving along the fixed rod is fitted on the rod body, and the limiting plate is located at the top of the spring. A moving column for moving up and down is fixedly installed at the top of the limiting plate, and an ejection plate for ejecting the metal plate processed inside the mold body is fixedly installed at the top of the moving column.

[0015] As a further improvement to this technical solution, the first drive assembly includes a threaded rod disposed within the support plate for driving two clamping and positioning assemblies to move in opposite directions. The front end of the threaded rod is fixedly mounted with a pulley for connecting to the second drive assembly via a belt. A slide rod for moving the clamping and positioning assemblies is fixedly mounted within the support plate.

[0016] As a further improvement to this technical solution, the clamping and positioning assembly includes a clamping and positioning plate disposed above the support plate for clamping and positioning the metal plate. A threaded sleeve plate for threaded connection with a threaded rod is fixedly installed at the bottom end of the clamping and positioning plate, and a fixing sleeve plate for fitting onto the slide rod is fixedly installed at the bottom end of the clamping and positioning plate.

[0017] As a further improvement to this technical solution, the second drive assembly includes a threaded rod II disposed in the slide groove for driving two cleaning assemblies to move in opposite directions. A motor for driving the threaded rod II to rotate is fixedly installed at the front end of the threaded rod II. A pulley II for connecting to the threaded rod II via a belt and a pulley II is fixedly installed on the rod body of the threaded rod II.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1.

In this metal plate bending processing device, the rotation of the threaded rod 2 can be driven by a motor, so that the threaded sleeve 2 located at the two threads of the threaded rod 2 can move in opposite directions along the threaded rod 2, so that the cleaning plate can clean the debris on the worktable. This achieves the goal of cleaning the worktable when clamping and positioning the metal plate and when releasing the clamping and positioning, so as to avoid the accumulation of debris on the workpiece.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Therefore, the present invention provides a bending processing apparatus for metal plates, see [link to apparatus]. Figures 1-9As shown, it includes a worktable 100, a mold device 300 at the top of the worktable 100, a stamping device 200 fixedly mounted at the top of the worktable 100 for bending metal plates in cooperation with the mold device 300, a clamping and positioning device 400 for clamping and positioning the metal plates above the worktable 100, and a cleaning device 500 for cleaning debris from the worktable 100 inside the worktable 100, with the clamping and positioning device 400 connected to the cleaning device 500; the mold device 300 includes a mold assembly 310 fixedly mounted at the top of the worktable 100 for bending metal plates in cooperation with the stamping device 200. The mold assembly 310 is provided with an ejection assembly 320 for ejecting the metal plate processed inside the mold assembly 310; the clamping and positioning device 400 includes a drive assembly 410 for rotation disposed inside the worktable 100, and a clamping and positioning assembly 420 for clamping and positioning the metal plate on the worktable 100 is threadedly connected to the rod of the drive assembly 410, and there are two clamping and positioning assemblies 420, and the two clamping and positioning assemblies 420 move in opposite directions; the cleaning device 500 includes a drive assembly 510 for rotation disposed inside the worktable 100, and a cleaning assembly 520 for cleaning the worktable 100 is threadedly connected to the shaft of the drive assembly 510.

[0036] For details, see Figure 2 and Figure 3 As shown, a support plate 102 for placing metal plates is fixedly installed on the top of the workbench 100. The left side of the support plate 102 is sloped to facilitate the quick removal of the metal plates after they have been bent by the stamping device 200 and the mold device 300. The top of the support plate 102 is provided with a through groove for placing the mold device 300. The top of the workbench 100 is provided with a slide groove 101 for moving the cleaning component 520.

[0037] Further, see Figure 4 As shown, the stamping device 200 includes a support frame 210 fixedly installed on the top of the worktable 100. A hydraulic rod 220 for vertical movement is fixedly installed on the frame of the support frame 210. A stamping head 230 for bending the metal plate in cooperation with the mold assembly 310 is fixedly installed at the bottom end of the hydraulic rod 220.

[0038] During operation, the metal plate can be bent by controlling the cooperation between the punch head 230 and the mold device 300 through the hydraulic rod 220 on the support frame 210. At the same time, the metal plate after processing can be removed by using the slope on the left side of the support plate 102.

[0039] Further, see Figure 2 and Figure 5As shown, the mold assembly 310 includes a mold body 311 fixedly installed on the top of the workbench 100, and the mold body 311 is located inside the support plate 102. The mold body 311 has a placement groove 312 for the pop-out component 320 to move, and the cross-section of the placement groove 312 is stepped, so as to prevent the pop-out component 320 from moving out of the mold body 311.

[0040] The pop-out component 320 includes four fixing rods 324 fixedly installed in the mold body 311, and the four fixing rods 324 are arranged in a rectangular array in the placement slot 312; a spring 325 is fitted on the rod body of the fixing rod 324.

[0041] A limiting plate 323 for moving along the fixed rod 324 is fitted on the rod body of the fixed rod 324, and the limiting plate 323 is located at the top of the spring 325. The shape and size of the limiting plate 323 are the same as the shape and size of the placement groove 312. A moving column 322 for moving up and down is fixedly installed at the top of the limiting plate 323, and the moving column 322 passes through the top of the mold body 311. An ejection plate 321 for ejecting the metal plate processed in the mold body 311 is fixedly installed at the top of the moving column 322.

[0042] Therefore, when it is necessary to bend the metal plate, the metal plate can be placed on the support plate 102, and the clamping and positioning device 400 can be used to clamp and position the metal plate above the mold body 311. Then, the hydraulic rod 220 on the support frame 210 controls the punch head 230 to press the metal plate, and then the clamping and positioning device 400 releases the clamp on the metal plate. Then, the hydraulic rod 220 controls the punch head 230 to punch into the mold body 311 and bend the metal plate. When the hydraulic rod 220 and the punch head 230 are disengaged from the mold body 311, under the elastic action of the spring 325, the limiting plate 323 can be moved upward along the four fixed rods 324, so that the ejector plate 321 in the mold body 311 can eject the processed metal plate and quickly discharge it along the left-side inclined support plate 102.

[0043] Further, see Figure 6 and Figure 7As shown, the drive assembly 410 includes a threaded rod 412 disposed within the support plate 102 for driving two clamping and positioning assemblies 420 to move in opposite directions. The front and rear ends of the threaded rod 412 can be connected to the plate body of the support plate 102 via bearings. The threaded rod 412 has two threads with opposite directions of rotation, so the clamping and positioning assemblies 420 located at the two threads can move in opposite directions along the threaded rod 412. A pulley 411 is fixedly installed at the front end of the threaded rod 412 for connecting to the drive assembly 510 via a belt. A slide rod 413 is fixedly installed within the support plate 102 for moving the clamping and positioning assemblies 420.

[0044] The clamping and positioning assembly 420 includes a clamping and positioning plate 421 disposed above the support plate 102 for clamping and positioning the metal plate. The clamping and positioning plate 421 has anti-slip stripes on its body. A threaded sleeve plate 422 for threaded connection with the threaded rod 412 is fixedly installed at the bottom end of the clamping and positioning plate 421. A fixing sleeve plate 423 for fitting onto the slide rod 413 is fixedly installed at the bottom end of the clamping and positioning plate 421.

[0045] Therefore, when it is necessary to position and clamp the metal plate on the support plate 102, the rotation of the threaded rod 412 can cause the threaded sleeves 422 at the bottom of the two clamping positioning plates 421 to move in opposite directions along the two threads on the threaded rod 412, so that the metal plate on the support plate 102 can be positioned and clamped, thus keeping the metal plate in the middle of the mold body 311.

[0046] Further, see Figure 8 and Figure 9 As shown, the second drive assembly 510 includes a threaded rod 512 disposed in the slide groove 101 for driving the two cleaning assemblies 520 to move in opposite directions. The front and rear ends of the threaded rod 512 are connected to the groove wall of the slide groove 101 through bearings to facilitate the rotation of the threaded rod 512. At the same time, the rod body of the threaded rod 512 is provided with two threads, and the threads of the two threads are turned in opposite directions, so that the cleaning assemblies 520 can move in opposite directions along the threaded rod 512. A motor 511 for driving the rotation of the threaded rod 512 is fixedly installed at the front end of the threaded rod 512. A pulley 513 for connecting to the threaded rod 512 through a belt and a pulley 411 is fixedly installed on the rod body of the threaded rod 512. A guide rod 514 for sliding the cleaning assembly 520 is provided at the left end of the threaded rod 512.

[0047] The cleaning assembly 520 includes a cleaning plate 521 disposed at the top of the workbench 100 for scraping debris from the workbench 100. A threaded sleeve 522 for threaded connection with the threaded rod 512 is fixedly installed at the bottom end of the cleaning plate 521. A fixing sleeve 523 for fitting onto the guide rod 514 is also fixedly installed at the bottom end of the cleaning plate 521.

[0048] Therefore, when it is necessary to clean up the debris that has fallen above the worktable 100, the rotation of the threaded rod 512 driven by the motor 511 can cause the threaded sleeve 522 located at the two threads of the threaded rod 512 to move in opposite directions along the threaded rod 512, so that the cleaning plate 521 can clean up the debris on the worktable 100.

[0049] In summary, this effectively solves the problem of machining deviation caused by the lack of a metal plate for clamping and positioning in existing devices; at the same time, it also solves the problem of debris falling from the worktable 100 and accumulating on the worktable 100.

[0050] Working principle: When bending of a metal plate is required, the metal plate can be placed on the support plate 102. The motor 511 drives the rotation of the threaded rod 512. Under the belt connection between the pulley 411 and the pulley 513, the rotation of the threaded rod 412 causes the threaded sleeves 422 at the bottom of the two clamping positioning plates 421 to move in opposite directions along the two threads on the threaded rod 412, thus positioning and clamping the metal plate on the support plate 102, thereby keeping the metal plate in the middle of the mold body 311. At the same time, the threaded sleeves 522 located at the two threads of the threaded rod 512 move in opposite directions along the threaded rod 512, thus allowing the metal plate to be bent. The sweeping plate 521 cleans the debris on the worktable 100; then the hydraulic rod 220 on the support frame 210 controls the punch head 230 to press against the metal plate, and then the clamping and positioning device 400 releases the clamping of the metal plate; then the hydraulic rod 220 controls the punch head 230 to punch into the mold body 311 and bend the metal plate; when the hydraulic rod 220 moves the punch head 230 away from the mold body 311, and under the elastic action of the spring 325, the limiting plate 323 can be moved upward along the four fixed rods 324, so that the ejector plate 321 in the mold body 311 can eject the processed metal plate and quickly discharge it along the left-side inclined support plate 102.
