Punching die for transmission cover

Abstract

The invention relates to a punching die for a transmission cover. A guide device is arranged between a lower die base and an upper die base, a concave die is arranged on the lower die base, and a cylindrical pin and an inner die pass between the concave die and the lower die base. The hexagonal screw is fixed and installed, the upper die base is provided with a die handle, the bottom surface of the upper die base is provided with a punch, a punch fixing plate is sleeved on the punch, and a punch fixing plate is provided between the upper die base and the upper die base. A backing plate, the upper end of the punch is sleeved with a discharge plate, the upper die base and the discharge plate are connected by a discharge screw, and the discharge screw between the fixed plate of the punch and the discharge plate is sleeved with a discharge plate. The first spring, the second spring is set between the punch fixing plate and the unloading plate, to ensure the quality of the finished product and high pass rate, the fast mold changing device reduces the preparation workload and preparation time for stamping production, and has a long service life. manufacturing cost.

Description

technical field [0001] The invention relates to a punching die for a transmission cover. Background technique [0002] Cold stamping is an advanced metal processing method. It has a series of advantages such as high production efficiency, low processing cost, high material utilization rate, stable product dimensional accuracy, simple operation and easy mechanization and automation. Therefore, it has been widely used in mass production. It is widely used, occupies a very important position in modern industrial production, and is an indispensable processing method in national defense industry and civilian industrial production. [0003] The transmission cover is an essential part of the washing machine. The production batch is relatively large. The maximum number of parts can be produced at the fastest speed in the shortest time, and at the same time the quality must be guaranteed. This requires the designer to pay attention to many problems in the design. The existing molds ...

Problems solved by technology

[0003] The transmission cover is an essential part of the washing machine. The production batch is relatively large. The maximum number of parts can be produced at the fastest speed in the shortest time, and at the same time the quality must be guaranteed. This requires the designer to pay attention to many problems in the design. The existing molds have high manufacturing costs, short service life, poor product quality, and need to be reprocessed, which cannot guarantee the quality of finished products and high pass rate. At the same time, the speed of mold change is slow, which increases the workload of stamping production preparations and Preparation time
