Embossing roller die manufactured by using steel strip

Abstract

The invention discloses an embossing roller die manufactured by using a steel strip. The embossing roller die comprises a pattern layer, a basal body and a spindle, wherein the hardness of the pattern layer is greater than or equal to 58 HRC; the embossing roller die is made of the steel strip on which heat treatment is not required to be performed; the steel strip is fixedly connected to the basal body through welding or magnetic coupling; then a pattern is machined on the pattern layer. The basal body and the spindle are made of carbon steel; the basal body is arranged on the spindle in a sleeving manner and the basal body is in interference fit with the spindle. According to the embossing roller die, the steel material consumption and the machining process of the die are greatly reduced, the production cost is reduced, and the production period is shortened; since the pattern layer is not required to be subjected to the heat treatment, heat treatment distortion is avoided and the geometric accuracy of the pattern is high.

Description

technical field [0001] The invention relates to the field of roll cutting forming dies, in particular to an embossing roll die made of steel strips. Background technique [0002] The working part of the embossing roller die is the pattern on the outer surface of the roller body. Since the depth of the pattern is generally 1-3 mm, only the surface layer of the roller body needs to have high hardness and high strength, while the internal hardness and strength of the roller body are not required to be high. [0003] In the prior art, the embossing roller mold body is made of solid mold steel bar, the amount of mold steel is large, and the cost of raw materials is high, especially the preparation and heat treatment process of super large diameter (>φ400mm) mold steel material is very poor. When manufacturing the prior art embossing roller mold, it is necessary to carry out heat treatment such as quenching and tempering on the whole roller body to ensure that the pattern has h...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an embossing roll die made of a steel strip with a hardness ≥ 58HRC and without heat treatment, so as to solve the problem of large amount of mold steel used in the prior art embossing roll die, high cost of raw materials, long processing cycle, and high production cost. problems and difficulties in the preparation and heat treatment of super-large diameter (>φ400mm) die steel materials
