Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a clamping mechanism for a metal forming machine. Background Technology

[0002] In the current metal sheet production and processing process, the metal sheet usually needs to be ground and polished or subjected to other fine processing. Before processing, the material needs to be fed and then limited. During feeding, the metal sheet needs to be pressed to prevent it from warping.

[0003] For example, Chinese patent document CN215918897U discloses a pressing device for an aluminum plate forming machine, including a conveying platform for conveying aluminum plates in the forming machine. A pressing mechanism is provided above the conveying platform. By rotating the ring handle, the sliding plate is pressed down, thereby pressing down the guide roller to press down and prevent the aluminum plate from warping during reforming, thus increasing accuracy. The front roller further prevents the aluminum plate from warping. The double pressing facilitates installation and disassembly. It can be adjusted at any time when changing aluminum plates of different thicknesses, making operation convenient.

[0004] The existing technology has the following problems:

[0005] In existing technology, when pressing the metal plate, the bottom end of the metal plate does not have roller support on the contact surface with the worktable, making it difficult to move the metal plate when it needs to be moved for feeding, thus reducing the practicality of the device. At the same time, after pressing the metal plate, the existing technology does not have a suitable drive mechanism to move the pressed aluminum plate, which also reduces the practicality of the device.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-5 As shown, a clamping mechanism for a metal forming machine includes a worktable 1. A connecting plate 11 is fixedly connected to the front of the top of the worktable 1. A clamping mechanism 2 is rotatably connected to the inner wall of the connecting plate 11. An auxiliary mechanism 3 is fixedly connected to the right side of the front of the worktable 1. The clamping mechanism 2 includes two mounting plates 21. The bottom end of the rear mounting plate 21 is fixedly connected to the rear of the top of the worktable 1. The bottom end of the front mounting plate 21 is slidably connected to the top of the worktable 1. A threaded rod 22 is threadedly connected to the bottom of the front mounting plate 21. The outer wall of the threaded rod 22 is rotatably connected to the inner wall of the connecting plate 11. The rear end of the threaded rod 22 is rotatably connected to the bottom of the rear mounting plate 21. The auxiliary mechanism 3 includes a motor 31 and two active bevel gears 36. The front end of the motor 31 is fixedly connected to the right side of the front of the worktable 1.

[0026] The aluminum plate 4 to be processed is pressed and fixed by the pressing mechanism 2, and then the aluminum plate 4 is driven by the auxiliary mechanism 3 so that the aluminum plate 4 can enter the next processing step on its own.

[0027] like Figure 2 , Figure 3 As shown, a guide rod 23 is slidably connected to the bottom of the front mounting plate 21. The rear end of the guide rod 23 is fixedly connected to the bottom of the rear mounting plate 21, and one end of the guide rod 23 is fixedly connected to the outer wall of the connecting plate 11.

[0028] By rotating the threaded rod 22, the mounting plate 21 located at the front moves on the outer wall of the threaded rod 22. At the same time, the mounting plate 21 located at the front slides on the outer wall of the guide rod 23, and the guide rod 23 guides the mounting plate 21. When the distance between the mounting plate 21 located at the front and the mounting plate 21 located at the rear is appropriate, the rotation of the threaded rod 22 is stopped.

[0029] like Figure 2 , Figure 3 As shown, a support plate 24 is fixedly connected to the bottom of the mounting plate 21, a pulley 25 is rotatably connected to the top of the support plate 24, an aluminum plate 4 overlaps the top of the pulley 25, a threaded rod 26 is threadedly connected to the top of the mounting plate 21, a mounting block 27 is rotatably connected to the bottom of the threaded rod 26, a pressure wheel 29 is rotatably connected to the outer wall of the mounting block 27, the outer wall of the pressure wheel 29 overlaps with the top of the aluminum plate 4, a guide block 28 is fixedly connected to one end of the mounting block 27, and the outer wall of the guide block 28 is slidably connected to the inner wall of the mounting plate 21.

[0030] The aluminum plate 4 to be processed is placed on the pulley 25, and the outer wall of the aluminum plate 4 is brought into contact with the outer wall of the rear guide wheel 373. Then, the threaded rod 26 is rotated, causing the threaded rod 26 to move downward on the inner wall of the mounting plate 21. The threaded rod 26 drives the mounting block 27 to move synchronously, and the mounting block 27 drives the guide block 28 to slide downward on the inner wall of the mounting plate 21. The guide block 28 limits and guides the mounting block 27, making the downward movement of the mounting block 27 more stable. At the same time, the mounting block 27 drives the clamping wheel 29 to move synchronously, so that the outer wall of the clamping wheel 29 is in close contact with the outer wall of the aluminum plate 4, thereby pressing the aluminum plate 4 and preventing the aluminum plate 4 from warping, thus achieving the effect of clamping.

[0031] like Figure 2 , Figure 4 and Figure 5 As shown, a rotating rod 32 is fixedly connected to the output end of the motor 31. The rear part of the outer wall of the rotating rod 32 is fixedly connected to the axis of the rear active bevel gear 36. The front part of the outer wall of the rotating rod 32 is slidably connected to the inner wall of the front active bevel gear 36. The rear end of the rotating rod 32 on the outer wall of the rotating rod 32 is rotatably connected to the rear end of the inner cavity of the worktable 1. A bearing 34 is slidably connected to the outer wall of the rotating rod 32. The rear end of the bearing 34 is fixedly connected to the front end of the front active bevel gear 36. A limit block 341 is fixedly connected to the inner wall of the bearing 34. The outer wall of the limit block 341 is slidably connected to the inner wall of the rotating rod 32. A retaining ring 35 is fixedly connected to the outer wall of the bearing 34. A fixing plate 33 is slidably connected to the outer wall of the retaining ring 35.

[0032] By starting the motor 31, the motor 31 drives the rotating rod 32 to rotate, which in turn drives the bearing 34 to rotate. The bearing 34 then drives the retaining ring 35 to rotate on the inner wall of the fixed plate 33. At the same time, the bearing 34 drives the active bevel gear 36 to rotate synchronously, so that the active bevel gear 36 meshes with the driven bevel gear 37. The driven bevel gear 37 drives the rotating shaft 371 to rotate synchronously.

[0033] like Figure 2 , Figure 4 As shown, a slide plate 38 is fixedly connected to the top of the fixed plate 33, and a slide rod 381 is slidably connected to the inner wall of the slide plate 38. One end of the slide rod 381 is fixedly connected to the right side of the inner cavity of the workbench 1. A fixed rod 372 is fixedly connected to the outer wall of the slide plate 38. A rotating shaft 371 is rotatably connected to the inner wall of the fixed rod 372. A driven bevel tooth 37 is fixedly connected to the bottom end of the rotating shaft 371. The bottom of the driven bevel tooth 37 meshes with the top of the driving bevel tooth 36. A guide wheel 373 is fixedly connected to the top of the rotating shaft 371. The outer wall of the guide wheel 373 overlaps with the outer wall of the aluminum plate 4.

[0034] When the rotating shaft 371 rotates, it drives the guide wheel 373 to rotate synchronously, thereby driving the aluminum plate 4 and making the aluminum plate 4 move so that it can enter the grinding device or cutting device on its own. This completes the driving and achieves the driving effect.

[0035] like Figure 2 , Figure 4 As shown, a connecting block 39 is fixedly connected to the right end of the slide plate 38. The outer wall of the connecting block 39 is slidably connected to the right side of the workbench 1. A fixing block 391 is fixedly connected to the right side of the connecting block 39. Fixing bolts 392 are threadedly connected to both the upper and lower parts of the fixing block 391. The left end of the fixing bolt 392 overlaps with the right end of the workbench 1.

[0036] Loosen the fixing bolt 392 so that the outer wall of the fixing bolt 392 is no longer pressed against the outer wall of the worktable 1, and the fixing block 391 can be pushed. The fixing block 391 drives the connecting block 39 to slide synchronously on the inner wall of the worktable 1. The connecting block 39 drives the slide plate 38 to move synchronously. After moving to the appropriate position, tighten the fixing bolt 392 to fix the fixing block 391, so that the connecting block 39 and the slide plate 38 cannot move, thus achieving the effect of limiting movement.

[0037] The working principle of this utility model is as follows: In use, based on the width of the aluminum plate 4, rotate the threaded rod 22 to move the front mounting plate 21 along the outer wall of the threaded rod 22. Simultaneously, the front mounting plate 21 slides along the outer wall of the guide rod 23, which guides the mounting plate 21. When the distance between the front and rear mounting plates 21 is appropriate, stop rotating the threaded rod 22. Then, place the aluminum plate 4 to be processed onto the pulley 25, ensuring the outer wall of the aluminum plate 4 contacts the outer wall of the rear guide wheel 373. Afterward, rotate the threaded rod 26 to move downward along the inner wall of the mounting plate 21. The threaded rod 26 drives the mounting block 27 to move synchronously. The mounting block 27 drives the guide block 28 to slide downwards on the inner wall of the mounting plate 21. The guide block 28 limits and guides the mounting block 27, making its downward movement more stable. At the same time, the mounting block 27 drives the clamping wheel 29 to move synchronously, so that the outer wall of the clamping wheel 29 abuts against the outer wall of the aluminum plate 4, thereby clamping the aluminum plate 4 and preventing it from warping. After that, the fixing bolt 392 is loosened so that the outer wall of the fixing bolt 392 is no longer abutting against the outer wall of the worktable 1, and the fixing block 391 can be pushed. The fixing block 391 drives the connecting block 39 to slide synchronously on the inner wall of the worktable 1. The inner wall slides, and the connecting block 39 drives the sliding plate 38 to move synchronously, so that the sliding plate 38 slides on the outer wall of the sliding rod 381. The sliding plate 38 drives the fixing plate 33 to move synchronously, so that the fixing plate 33 drives the bearing 34 to slide on the outer wall of the rotating rod 32. The bearing 34 drives the limiting block 341 to slide on the inner wall of the rotating rod 32. The limiting block 341 limits the bearing 34, so that the bearing 34 can only move horizontally on the outer wall of the rotating rod 32. This causes the sliding plate 38 to drive the fixing rod 372 and the guide wheel 373 to move synchronously, so that the guide wheels 373 at the front and rear clamp the aluminum plate 4. Then, the fixing bolt 392 is tightened again to fix the fixing block 391, so that the connecting block 39 and the sliding plate The inability of 38 to move serves as a limiting mechanism. Then, motor 31 is activated, driving the rotating rod 32 to rotate. This rotating rod 32, in turn, drives the bearing 34 to rotate, causing the retaining ring 35 to rotate on the inner wall of the fixed plate 33. Simultaneously, the bearing 34 drives the active bevel gear 36 to rotate synchronously, meshing with the driven bevel gear 37. The driven bevel gear 37 then drives the rotating shaft 371 to rotate synchronously, which in turn drives the guide wheel 373 to rotate synchronously. This allows the guide wheel 373 to drive the aluminum plate 4, enabling it to move and enter the grinding or cutting device. This completes the driving process and significantly improves the user experience.
