Embodiment Construction

[0019] In order to describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following is a detailed description in conjunction with the embodiments and accompanying drawings.

[0020] See figure 1 , 2 3. This embodiment provides an embossing roller die made of steel belt, which includes a pattern layer 11, a base 12 and a mandrel 13. The pattern layer 11 is made of steel strip with a hardness ≥ 58HRC and no heat treatment is required. The pattern layer 11 is fixed on the base body 12 by welding, and then a pattern is processed on the pattern layer. The base 12 and the mandrel 13 are made of carbon steel, and the base 12 is sleeved on the mandrel 13 with interference fit.

[0021] In the present invention, the pattern layer 11 can also be fixed on the base 12 by means of magnetic coupling or the like. Of course, other feasible fixing methods can also be adopted.

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...
