A chamfering equipment for metal printing cylinder

Abstract

The invention discloses a chamfering device for a metal printing roller. The chamfering device comprises a rack which is provided with a feeding device, a pushing device, a roller fixing device, a chamfering device body and a discharging device. The feeding device comprises a containing box. The containing box is provided with a discharging transverse hole. The pushing device comprises a push rod and a first cylinder. The push rod is arranged on the portion, corresponding to the discharging transverse hole, of the rack. The push rod is fixedly connected with the first cylinder. According to the chamfering device for the metal printing roller, the whole equipment achieves feeding, chamfering and discharging operation, the chamfering speed is high, and efficiency is high.

Description

Technical field [0001] The invention relates to a chamfering device, in particular to a chamfering device for a metal printing roller. Background technique [0002] Generally used as rollers for optical film manufacturing, nanoimprinting, large and small electronic imaging printers, and high-precision printing, polystyrene films and polyimide films with a wall thickness in the range of 0.03-0.3mm are often used. In addition, some are electroplated in nickel plating, and are produced by the nickel electroforming method in which electroformed products in which nickel metal is precipitated on the cylindrical matrix are extracted from the matrix. The rollers for the above-mentioned purposes need to be used in the process of continuous heating, pressing, cooling, peeling, etc., so it is desirable that they have good thermal conductivity and heat resistance. In addition, because the rollers for the above-mentioned purposes are used as a rotating body, Therefore, excellent fatigue stre...

Problems solved by technology

[0003] However, if resin materials such as polystyrene and polyimide are used as the roller body, the thermal conductivity of the roller body is poor, and nickel electroformed products are used as the roller body, although its thermal conductivity is excellent, but at temperatures above 180 ° C High temperature will cause thermal embrittlement, so in the printing equipment industry, roller bodies made of the above two materials are gradually withdrawn from the market, replaced by metal printing rollers made of thin-walled metal cylinders

[0004] For metal printing rollers made of thin-walled metal cylinders, the traditional processing equipment is to use a spinning machine. During the spinning process, the metal cladding materials of aluminum, stainless steel, nickel, titanium, copper or stainless steel and copper etc. as materials, using the spinning parts to rotate around the mandrel while moving the axis to achieve plastic processing, using this thin-walled metal cylinder can be made to play the metal's excellent heat conductivity, heat resistance, fatigue strength, Rigid roller, the end of the resulting metal printing cylinder needs to be chamfered, but the chamfering device now has poor chamfering effect and low efficiency
