Problems solved by technology

[0005] 1. The use of multiple stretching processes and the need to switch multiple stations, the production process is too cumbersome, the processing cycle is long, and the production efficiency is low
[0006] 2. Excessive production operations are likely to produce more unqualified products, and the scrap rate is high. It is understandable that the stretching process itself is a process that is prone to produce defective products, such as prone to cracking, or excessive local internal stress, and easily damaged
[0007] 3. Occupies a lot of large equipment, and invests more molds and personnel, resulting in high production costs
[0013] 1. Relying on the rotation of the workpiece to realize its round processing, it is impossible to process

Embodiment Construction

[0052] For the cup body processing method, according to the present invention, its improvements are mainly reflected in the two levels of mouth processing and bottom processing. The special equipment used will be explained below.

[0053]The first is bottom shaping: For containers that need bottom shaping, it is more common to see such as the inner pot of the rice cooker, the ordinary deep pot, etc., the bottom of which needs to have a certain R angle. On the one hand, it is easy to clean, and on the other hand On the one hand, this kind of products are generally produced by deep drawing process, which belongs to cold processing process. When deep drawing is deep, it often cannot be formed at one time, and it needs multiple deep drawing to form, otherwise it is easy to crack.

[0054] The deep drawing and stretching here belong to different processes, the deep drawing belongs to the forming process, and the drawing belongs to the processing process after the forming process. Deep

Abstract

The invention discloses a cup body processing method. The method includes the steps for a first cup body middle piece of an opening to be formed, the opening is trimmed according to the given size, and an opening forming blank is formed; then, the opening of the opening forming blank is inwards coiled to be round to form an opening coiled body which is marked as a second cup body middle piece; and the opening coiled body is pressed in the axial direction of a cup body, and a containing cavity in the opening coiled body is eliminated. According to the basic principle of the cup body processing method, the container opening is internally turned and pressed flatly so as to eliminate the opening containing cavity, so that dirt cannot be accumulated in the container opening.
