Problems solved by technology

[0006] Some manufacturers have improved the ejector rod structure by drilling holes in the head of the ejector rod, or adding threaded mechanisms, or adding other self-locking mechanisms, but the above improvements (or improvements) require reprocessing of the ejector rod, and Changed the head structure of the ejector pin to reduce the force-bearing area, requiring a lot of modification costs, which will affect the strength and service life of the ejector pin

Abstract

The invention discloses an ejecting rod drawing device of a large stamping die. When a working platform provided with a die is started to depart from a stamping position of a stamping machine tool and the die is put down, the ejecting rod (8) is drawn. The ejecting rod drawing device is characterized by having a rod-shaped structure; and the position adjacent to one end of the device is provided with a magnetic sucking structure, and the other end is provided with a handle (9). By adopting the technical scheme, after the working platform is started for the first time and the die is put down, the ejecting rod can be directly drawn by using the drawing device; the invention has the characteristics of simple manufacturing process, simple and convenient operation, long service life, low maintenance cost, and the like and can effectively shorten the manufacturing period of the die, prolong the use period of the die and save great time, labor and materials.

Description

technical field [0001] The invention belongs to the technical field of pressure manufacturing process equipment, and relates to a die structure technology for cold stamping processing, and more specifically, the invention relates to a ejector pin extracting device of a large stamping die. Background technique [0002] In modern automobile production, large cold dies are used to manufacture structural components. Among them, a large number of parts are formed by drawing, and this type of mold needs to use a ejector mechanism. For some equipment with low degree of automation, the replacement process of the ejector pin is as follows: [0003] The workbench (with mould) is opened → the mold is lifted → the workbench is moved in → the original ejector pin is ejected → the original ejector pin is taken out → the position of the ejector pin is replaced → the workbench is opened → the mold is hoisted → the workbench is moved in. [0004] During this process, the workbench needs to...
