Integral embossing roller and manufacturing method thereof

Abstract

The invention belongs to non-cutting metal machining, particularly belongs to embossing rollers, and relates to an integral embossing roller. The integral embossing roller is characterized in that theroller is composed of a center shaft and bearings, roller necks are arranged at the two ends of the center shaft and used for installing the bearings, rolling grooves are machined in the surface of the middle of the center shaft, the multiple rolling grooves are distributed at equal intervals, and every two adjacent rolling grooves are separated through a cylindrical section. The integral embossing roller has the advantages that the structure is simple and compact, more rolling grooves can be arranged in the working area with the same length, assembling is easy, the finished product rate of machined products is high, and the phenomena of pattern dislocation and torsional deformation are avoided; an integral die is good in rigidity and high in strength, and compared with a bushing combinedroller, the bushing replacement time does not exist, so that the time is saved; the roller can be remachined and used after being worn; and in the same axial size of the integral roller, the number of arranged and machined wires is larger than that of bushing type rollers, and therefore the production efficiency of the integral roller is high.

Description

technical field [0001] The invention belongs to non-cutting metal machining; in particular, it belongs to embossing rolls. .Background technique [0002] like Figure 1-5 As shown, the roll is the main working part and tool for continuous plastic deformation of the metal on the rolling mill. It is mainly composed of three parts: the central shaft 1, the insert 3 and the bearing 2, as shown in figure 1 As shown, the multi-section insert is set outside the central shaft, and the center shaft and the insert are positioned and driven by the flat key 5. The insert is the middle part of the roll that actually participates in rolling metal, and the surface of the insert is processed with rolling grooves 31 at intervals. The two ends of the rolling groove and between the two rolling grooves are smooth cylindrical sections 32. Generally, an insert has two rolling grooves, and the two ends of the central shaft are roll necks 11, which are used for bearing installation. The central s...

Problems solved by technology

[0005] The present invention is an improvement on the basis of the prior art. Structurally speaking, the central shaft and the inlay are combined into one, and the inlay is eliminated, and there is no need for nuts to fix it. Rolling grooves, so as to eliminate the fit gap and solve the defects of product pattern dislocation and torsional deformation
