DETAILED DESCRIPTION

[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] Examples, such as Figure 1 to Figure 4 As shown, a steel cup punching and drawing die for diamond synthesis includes a punching and drawing die 5 body, which includes a die frame 1, an outer die fixed template 2 and a base 3 arranged in sequence from top to bottom. The establishment of the above-mentioned equipment components are all existing mature and commonly used technical means, which can be effectively known to technicians in the relevant technical field, and the details are not repeated here; a first material return device 4 is arranged in the die frame 1, and its functions are to ensure the demoulding of the workpiece molding and to tighten the punching and drawing process to ensure the effective progress of the production and processing work. A punching and drawing die 5 is arranged in the outer die fixed template 2 to ensure the effective molding of the steel cup 7 workpiece and the molding quality. The inside of the punching and drawing die 5 A trimming assembly 6 is provided at the lower side, which is mainly used for trimming the end edge of the steel cup 7, saving processing procedures, ensuring the working process, saving energy and reducing consumption, and improving the functionality of use. A steel cup 7 is placed inside the trimming assembly 6, and a second material removal device 8 is provided above the base 3. A mold core punch 9 is provided in the second material removal device 8, and it abuts against the steel cup 7, which provides convenient conditions for the molding of the steel cup 7 and effectively meets the use requirements. Furthermore, the material of the steel cup 7 is Cr12MoV mold steel combined with YG16 cemented carbide, and the mold core is Cr12MoV mold steel hot-coated with tungsten carbide wear-resistant coating, which relatively improves the service life of the equipment workpiece, reduces the production cost, and ensures the molding quality of the product;

[0020] In the above process: the established punching and stretching die 5 is used to ensure the punching and stretching work of the steel cup 7, to ensure the preparation of the finished steel cup 7, and to ensure the work progress; the established trimming component 6 can be used to trim the edges and corners of the manufactured steel cup 7, thereby improving the forming quality of the workpiece, shortening the processing steps, and improving the work progress, and effectively meeting the use requirements; the device has a reasonable design, a simple structure, and is easy to process, and can integrate the punching, stretching, and trimming processes, thereby effectively shortening the workpiece forming time, improving the finished product processing and forming quality, ensuring the work progress, reducing production costs, saving time and effort, and effectively meeting the production and processing needs.

[0021] In order to ensure the effective implementation of the trimming work, the trimming component 6 includes a mounting sleeve 61 with a hollow T-shaped ring design, and a trimming knife 62 is arranged below the mounting sleeve 61. Specifically, on the one hand, the mounting sleeve 61 is detachably fixed to the punching and drawing die 5, and on the other hand, with the cooperation of the limiting column 611, the guide groove 51 and the limiting groove 52, the trimming component 6 is stably established.

[0022] In order to fully ensure the installation stability of the trimming assembly 6, a guide groove 51 with an inclined design is opened at the lower inner side of the punching and drawing die 5, a limiting groove 52 is arranged at the end of the guide groove 51, and a limiting column 611 is arranged on the outer side of the mounting sleeve 61. It is specifically described as follows: a notch with an L-shape design is opened at the lower inner side of the punching and drawing die 5, so that the mounting sleeve 61 and the punching and drawing die 5 can be threadedly connected. When the threaded connection is performed, the limiting rod corresponds to the lower end of the limiting groove 52. As the mounting sleeve 61 is screwed in, the limiting rod moves along the guide groove 51 until the limiting rod and the limiting groove 52 are adapted and engaged. The cooperation between the two greatly improves the connection stability between the equipment components, ensuring that the equipment components have good use effects and meet the use requirements.

[0023] In order to further improve the rationality of the device, the trimming knife 62 is designed in a conical shape, and its lower end face is designed to be closed. Specifically, the trimming knife 62 is designed to be closed from top to bottom, and the lower end face of the trimming knife 62 is designed to be closed from the upper inside to the lower side, and the inner lower side of the lower end face is in contact with the outer end face of the steel cup 7. While ensuring the completion of the trimming action, it can also save material costs, avoid waste, and meet usage requirements.
