Description

Method for machining roller sharp corner

Technical Field

The invention relates to the technical field of circle-pressing and circle-cutting, in particular to a method for processing a sharp corner of a roller.

Background

A round-pressing round die cutting machine is a cutting machine and is commonly used for mass production. The roller rotates continuously when the rotary die cutting machine works, so that the production efficiency of the rotary die cutting machine is the highest among various die cutting machines. However, the die-cutting plate needs to be bent into a curved surface, the plate making is troublesome, the cost is high, and certain technical difficulty exists. The die cutting mode of the circular die cutting machine is generally divided into a hard cutting method and a soft cutting method. The hard cutting method is that a cutter is in hard contact with the surface of a pressure roller during die cutting, so that the die cutting cutter is easy to wear. The soft cutting method is to cover a layer of engineering plastics on the surface of the pressure roller, and when die cutting is carried out, the cutter can have a certain cutting amount, so that the cutter can be protected, complete cutting can be ensured, but the plastic layer needs to be replaced regularly.

In the round-pressing and round-cutting industry, a roller structure needs to suck cut waste materials from the side surface of a roller and discharge the waste materials, the waste materials are provided with sharp corners at certain positions, the waste materials are difficult to machine and remove by a common method in the roller machining, and the rotating parts of the roller are low in efficiency and difficult to operate by a common electrode discharge sharp corner machining method. Therefore, the slotting tool with strong pertinence for processing the sharp corner is designed, and the problem can be quickly and conveniently solved.
