Description

Technical Field

[0001] This utility model relates to the field of driving rake tooth processing technology, specifically a stamping and bending device for driving rake tooth processing. Background Technology

[0002] The stamping and bending equipment used for processing rake teeth operates on the principle of stamping and bending the material blocks of rake teeth by using an upper die to press and bend the lower die, thereby enabling the rake teeth to achieve the required shape and curvature.

[0003] However, existing stamping and bending equipment for processing drive rake teeth leaves processing debris on the surface of the lower die after the processing of the drive rake teeth. Generally, workers need to process all the drive rake teeth in a batch before manually cleaning the debris from the surface of the lower die. Because the debris is not cleaned in time, it will affect the subsequent processing of drive rake teeth. At the same time, when the stamping and bending equipment is working, the upper die applies pressure to the lower die to complete the stamping and bending process. This pressure is transmitted to the lower die. Since the lower die is fastened to the worktable with bolts, under long-term stamping pressure, the bolts will gradually loosen, which will cause the subsequent stamping and bending to deviate. Utility Model Content

[0004] The purpose of this invention is to provide a stamping and bending device for driving the processing of rake teeth, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping and bending device for driving rake tooth processing, comprising a worktable and a hydraulic telescopic rod disposed on the top of the worktable, and further comprising:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5As shown, a stamping and bending device for processing drive rake teeth includes a worktable 1, which can process the drive rake teeth. A hydraulic telescopic rod 2 is provided on the top of the worktable 1, and an upper die 3 is fixedly connected to the bottom of the hydraulic telescopic rod 2. Under the action of the hydraulic telescopic rod 2, the upper die 3 can move up and down. A lower die 4 is bolted to one side of the worktable 1. The lower die 4 can place the drive rake teeth on its top, and the upper die 3 can be used to bend the drive rake teeth. A connecting rod 5 is fixedly connected to one side of the hydraulic telescopic rod 2, and a rotating mechanism 6 is provided on one side of the connecting rod 5. Under the action of the hydraulic telescopic rod 2 and the connecting rod 5, the rotating mechanism 6 can operate. A sleeve 7 is slidably connected to the top of the worktable 1. Under the action of the rotating mechanism 6, the sleeve 7 can reciprocate on the top of the worktable 1. A guide rod 8 is fixedly connected to the top of the worktable 1. The surface of the guide rod 8 is slidably connected to the inner cavity of the sleeve 7. Under the action of the guide rod 8, the sleeve 7 is effectively prevented from shifting position during operation, increasing the stability of the sleeve 7 during movement. A brush 9 is rotatably connected to one side of the sleeve 7. Under the action of the movement of the sleeve 7, the brush 9 can clean the broken parts on the top of the lower mold 4. The debris is cleaned up, effectively reducing the impact of debris on the subsequent processing of the drive rake teeth, thereby improving the processing effect of the equipment on the drive rake teeth. A guide block 10 is rotatably connected to the other end of the brush 9. The surface of the guide block 10 is slidably connected to one side of the worktable 1. Under the action of the guide block 10, the positional deviation of the brush 9 during movement is effectively reduced, increasing the stability of the brush 9 during movement. A protective cover 11 is rotatably connected to the top of the worktable 1. The bottom of the protective cover 11 is movably connected to one side of the lower mold 4. The protective cover 11 can protect the bolts of the lower mold 4, effectively preventing damage to the drive rake teeth. If the lower mold 4 becomes loose during tooth processing, a limiting mechanism 12 is provided on one side of the protective cover 11, and a compression spring 13 is fixedly connected to one side of the worktable 1. With the cooperation of the limiting mechanism 12 and the compression spring 13, the protective cover 11 can be limited, which increases the stability of the protective cover 11 during operation. A protective rod 14 is fixedly connected to the surface of the worktable 1. The protective rod 14 is located at the center of the compression spring 13. Under the action of the protective rod 14, the compression spring 13 is effectively prevented from shifting its position during compression, which increases the stability of the compression spring 13 during operation, thereby improving the stability of the equipment.

[0023] The rotating mechanism 6 includes a gear rack 61. One side of the gear rack 61 is fixedly connected to one end of the connecting rod 5, and the other side of the gear rack 61 is meshed with a spur gear 62. One side of the spur gear 62 is fixedly connected to a reciprocating threaded rod 63, and the other end of the reciprocating threaded rod 63 is rotatably connected to one side of the worktable 1. The surface of the reciprocating threaded rod 63 is threadedly connected to the inner cavity of the sleeve 7. With the cooperation of the hydraulic telescopic rod 2 and the connecting rod 5, the gear rack 61 can rotate the reciprocating threaded rod 63 through the spur gear 62. The reciprocating threaded rod 63 causes the brush 9 to reciprocate through the sleeve 7, which allows the brush 9 to clean the debris on the surface of the lower mold 4, effectively reducing the impact of debris on the subsequent processing of the rake teeth, thereby improving the practicality of the equipment.

[0024] The limiting mechanism 12 includes a limiting plate 121. The surface of the limiting plate 121 is slidably connected to the inner cavity of the protective cover 11. A rotating rod 122 is rotatably connected to the bottom of the limiting plate 121. A moving block 123 is fixedly connected to the bottom of the rotating rod 122. The surface of the moving block 123 is slidably connected to the surface of the worktable 1. One side of the moving block 123 is fixedly connected to one side of the compression spring 13. Under the action of the moving block 123, the compression spring 13 can be compressed on the surface of the worktable 1. The moving block 123 moves the limiting plate 121 out of the inner cavity of the protective cover 11 through the rotating rod 122, so that the protective cover 11 can rotate away from the lower mold 4, thereby facilitating the replacement of the lower mold 4 by the operator and limiting the bolts connecting the lower mold 4 and the worktable 1.

[0025] Working principle: First, the operator places the drive rake teeth to be processed on top of the lower mold 4. Under the action of the hydraulic telescopic rod 2, the upper mold 3 can process the drive rake teeth on top of the lower mold 4. After processing, the operator removes the processed drive rake teeth. Under the action of the connecting rod 5, the gear rack 61 can rotate the reciprocating threaded rod 63 through the spur gear 62. The reciprocating threaded rod 63, through the sleeve 7, causes the brush 9 to clean the debris on the surface of the lower mold 4. When the operator needs to replace the lower mold 4, the compression spring 13 can be compressed under the action of the moving block 123, allowing the moving block 123 to move the brush 9 to replace the lower mold 4. The moving block 123 moves the limiting plate 121 out of the inner cavity of the protective cover 11 through the rotating rod 122. Then, the protective cover 11 is rotated away from the lower mold 4, allowing the operator to remove the bolts connecting the lower mold 4 to the workbench 1. After the new lower mold 4 is installed, the protective cover 11 is rotated towards the lower mold 4, so that the bottom of the protective cover 11 contacts the top of the bolt. Under the action of the compression spring 13, the moving block 123 can drive the limiting plate 121 to move into the interior of the protective cover 11 through the rotating rod 122, so that the limiting plate 121 can limit the protective cover 11. Then the operator can continue processing.
