Description

Technical Field

[0001] The utility model relates to the technical field of shell shell extraction, in particular to an automatic shell shell extraction device. Background Art

[0002] During the production process of high-pressure shells, it is necessary to make the shell drawing, that is, to use a special mold to draw out a shape that meets the size at the shell opening under the action of hydraulic external force, so as to connect with the cylinder section and improve the sealing. However, many drawing equipment require manual operation of the machine to send and unmold the mold, and in the process of drawing, due to the action of the mold tension, it is easy to cause displacement during the drawing process, affecting the drawing forming, affecting the sealing performance and other problems, thereby reducing the processing efficiency. In addition, the punch and the connecting rod are mostly locked by tightening the nut, which is inefficient, has extremely high requirements on the bearing capacity of the nut, and has poor durability. At the same time, the shell and the punch are aligned by marking, measuring, etc., which is inefficient, and the cylinder cannot be fixed after alignment, resulting in displacement of the shell during the drawing process, affecting the accuracy of the drawing position, and uneven drawing leading to cracking. For this reason, we propose an automatic drawing equipment for high-pressure shells. Utility Model Content
