Description
Technical Field
The invention relates to the field of processing equipment of metal hollow bodies, in particular to a core rod structure for carrying out auxiliary supporting and positioning on the metal hollow bodies in a non-contact trimming process of the metal hollow bodies.
Background
The metal hollow body is a metal cylindrical body with one end open, such as a metal can and a power battery shell. Taking a metal can (two cans made of iron, aluminum and the like) as an example, a metal can is generally composed of a can lid and a can body, and after the can body is drawn and molded, the can body is cut in the height direction so as to make the can body uniform in height and remove burrs at a can opening, so that a can opening trimming device is used.
Most of the existing trimming devices for metal cans are mechanical trimming devices, and laser trimming devices are adopted in a few cases. Regardless of the type of trimming device employed, a mandrel structure is used to assist in positioning the metal can for trimming it. The existing core rod structure has the following defects:
1. the structural design has defects, so that the structure is complex, the control difficulty is high, the reliability is low and the cost is high;
2. the problem that the opening of the metal can is not round cannot be effectively solved, so that the cutting quality is unstable, and even the phenomenon of incomplete cutting exists;
3. the problem of clearing slag on the inner wall of the metal tank during cutting cannot be effectively solved, so that pollution in the tank is caused.
Therefore, how to solve the above-mentioned drawbacks of the prior art is a subject to be studied and solved by the present invention.
Disclosure of Invention
