Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example (b):

as shown in fig. 1 to 6, a high-efficiency stapler handle bending die includes an upper die plate 11 and a lower die plate 12 located below the upper die plate 11. The lower template 12 is fixed on a workbench 21, the upper template 11 is driven by an air cylinder or a hydraulic cylinder, and the air cylinder or the hydraulic cylinder is fixed on a supporting frame 22. The table 21 is located inside the support frame 22.

A pressing block 13 is fixedly connected to one side of the upper template 11 facing the lower template 12, and a placing groove 31 corresponding to the handle of the anastomat and a connecting groove 32 corresponding to the pressing block 13 are formed in the lower template. The coupling groove 32 is located at the middle of the placement groove 31.

The blank 10 of the handle of the anastomat is placed in the placing groove 31, the air cylinder or the hydraulic cylinder is started, the upper template 11 moves downwards, the pressing block 13 is placed in the connecting groove 32, and the blank 10 of the handle of the anastomat is bent in the connecting groove 32 to obtain the finished product 100 of the handle of the anastomat.

A squeegee 41 is provided on a side of the lower board 12 facing the upper board 11, and the squeegee 41 is positioned at an opening of the placement groove 31. The scraper 41 is slidably connected to a support 42 integrally provided on the lower die plate 12 via an elastic member 43, and the elastic member 43 is a spring. A displacement slope 44 for abutting against the press block 13 is opened on the side of the scraper 41 facing the upper die plate 11, and the displacement slope 44 is located at one end of the scraper 41 close to the placement groove 31.

The lower template 12 is provided with a sliding chute 51 communicated with the connecting groove 32, and the sliding chute 51 is positioned on the lower surface of the lower template 12; the chute 51 is provided in a T-shape in cross section. A supporting block 52 is slidably connected in the sliding groove 51, and the supporting block 52 is used for blocking the lower end of the connecting groove 32. The upper mold plate 11 moves away from the lower mold plate 12, and the linkage mechanism 6 drives the supporting block 52 to move out of the connecting groove 32, so that the finished product 100 of the stapler handle falls out of the connecting groove 32.

Wherein the linkage 6 comprises a gear 61, a first rack 62 and a second rack 63. One end of the first rack 62 is fixed to the lower surface of the upper mold plate 11 and the first rack 62 is placed vertically. The gear 61 is rotatably connected to the lower template 12, one end of the second rack 63 is connected to the supporting block 52, and the first rack 62 and the second rack 63 are respectively engaged with the gear 61. The longitudinal direction of the second rack 63 is parallel to the longitudinal direction of the slide groove 51.

The upper mold plate 11 moves downwards, the first rack 62 is meshed with the gear 61, the gear 61 rotates, then the gear 61 drives the second rack 63 to move, and the second rack 63 pushes the supporting block 52 to move along the sliding groove 51, so that the supporting block 52 blocks the lower end of the connecting groove 32. And as the upper die plate 11 continues to move downwards, the pressing block 13 and the connecting groove 32 work together to press the blank 10 to obtain the finished product 100. As the upper mold plate 11 moves upwards, the first rack 62 drives the gear 61 to rotate, the gear 61 drives the second rack 63 to move, and the second rack 63 moves the supporting block 52 away from the connecting groove 32, so that the resetting is realized. The finished product 100 falls out of the connecting slot 32 by gravity.

The second rack 63 includes a sleeve 71, a spring 72, and an inner rod 73. The outer wall of the sleeve 71 is engaged with the gear 61, and the inner rod 73 is slidably coupled in the sleeve 71 and has an end remote from the sleeve 71 fixedly coupled to the support plate. The spring piece 72 is located in the sleeve 71, and two ends of the spring piece are respectively connected with the inner rod 73 and the inner wall of the sleeve 71.

Through the deformation of the spring plate 72. When the upper die plate 11 moves upwards, the gear 61 drives the sleeve 71 to move, and the position of the inner rod 73 is not changed, namely the position of the supporting block 52 is not changed in the deformation process of the elastic sheet 72. As the upper die plate 11 continues to move, the inner rod 73 is moved, thereby disengaging the support block 52 from the connecting slot 32. That is, the finished product 100 stays in the connecting groove 32 for a period of time and falls down again, so as to reduce the resilience caused by the elastic deformation of the handle of the stapler and improve the quality of the finished product 100.

A guide pipe 9 is arranged on one side of the lower template 12 back to the upper template 11, and a connecting groove 32 is arranged in the guide pipe 9 and is provided with a communicating groove on the side wall of the guide pipe 9, so that the supporting block 52 can pass through the communicating groove.

In order to enable the finished product 100 to reduce friction for better fall, a driving roller 8 is rotatably attached to the inner wall of the connecting groove 32.

In order to facilitate the worker to place the blank 10 in the placing groove 31, a plurality of anti-slip grooves 411 are opened on the side of the scraper 41 facing the upper die plate 11.

In summary, in use, the scraper 41 is pushed away from the placing slot 31, the blank 10 of the handle of the stapler is placed in the placing slot 31, the scraper 41 is released, and the scraper 41 is restored by the elastic force of the elastic member 43. Then, the air cylinder or the hydraulic cylinder is started, the pressing block 13 moves downwards and extrudes and deforms the blank 10 in the connecting groove 32 to obtain a finished product 100, and then the upper die plate 11 moves upwards. By the interference of the scraper 41 with the side wall of the pressing block 13, when the product 100 moves upward along with the pressing block 13 and interferes with the scraper 41, the product 100 falls into the connecting groove 32. As the upper die plate 11 continues to move up, the supporting block 52 is removed from the connecting groove 32, and the finished product 100 falls into the guide pipe 9 and can be transferred to the collection box to improve the production efficiency.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
