The center shaft and the insert sleeve are formed by machining and assembling, the two ends of the insert sleeve are locked by nuts 7, the insert sleeve is offset in the axial direction or the circumferential direction (radial direction) of the center shaft due to the machining error of the end faces of the insert sleeve and the installation clearance, and the upper patterns and the lower patterns of a product are misplaced in the process of rolling a metal wire, so that torsional deformation occurs, and the rejection rate is high. As shown in fig. 4 and 5, the sides 311 of the grooves are perpendicular to the center line, and the profile is easy to slip when entering. The rolls may be arranged in a roll stand in the form of two rolls, three rolls, four rolls or multiple rolls.
Disclosure of Invention
The invention aims to overcome the defects of the existing metal wire rolling process, and provides an integral embossing roller which can better overcome the torsional deformation of metal rolling and the dislocation of upper and lower patterns so as to improve the yield.
The invention adopts the technical scheme that the integral embossing roller is characterized in that the roller consists of a central shaft and bearings, roller necks are arranged at two ends of the central shaft, the roller necks are used for installing the bearings, the surface of the middle part of the central shaft is provided with a plurality of grooves which are uniformly distributed at intervals, and adjacent grooves are separated by cylindrical sections.
The application is improved on the basis of the prior art, structurally combines the central shaft and the insert sleeve into a whole, cancels the insert sleeve, does not need nut fixation, and directly processes a rolling groove on the surface of the central shaft, thus eliminating fit clearance and solving the defects of dislocation and torsional deformation of patterns of products. The two end surfaces of the prior insert sleeve are cylindrical sections, the space between two insert sleeves is large, the space between two insert sleeves is shorter, the space between two insert sleeves is uneven, and the insert sleeves are even in space and compact in space.
The pressing dies for processing the surfaces of the two sides of the rolling groove are male dies, the height of each male die is larger than the depth of the designed pattern, and the height difference of the male dies is 5-10% of the depth of the designed pattern. The pressed pattern is clear.
The height of the male die is larger than the depth of the designed pattern, and the height difference of the male die and the male die is 5-10% of the depth of the designed pattern.
The sides of the rolling groove incline to two sides and are in a horn shape. The top of the rolling groove is outwards stretched to facilitate extrusion guiding, and meanwhile, the rolling groove is a holding part for the rest after material extrusion, so that the internal stress of the material is reduced.
The included angle between the side edge of the rolling groove and the central line of the roller body is 95-100 degrees.
The material of the central shaft is composed of low nickel spheroidal graphite infinite chilled cast iron, and the alloy cast iron comprises 3.65% of C, 1.65% of Si, 0.96% of Mn, 0.81% of Ni, 0.91% of Cr, 0.39% of Mo, 0.025% of Re, 0.055% of Mg, 0.21% of P and 0.007% of S.
A method for manufacturing an integral embossing roller includes machining roller necks at two ends of a central shaft, machining grooves on the surfaces of the middle of the central shaft, machining male dies for pressing patterns on the surfaces of two sides of the grooves by using a laser engraving machine, wherein the height of each male die is greater than the depth of a designed pattern, and the height difference of each male die and each male die is 5-10% of the depth of the designed pattern.
The invention has the advantages of simple and compact structure, working area with the same length, more grooves can be arranged, the assembly is easy, 1) the finished product rate of processed products is high, the phenomena of pattern dislocation and torsional deformation can not occur, 2) the integral type die has good rigidity and high strength, the stability of the product quality is easy to ensure, 3) compared with a sleeved combination type roller, the time for changing the sleeve is not existed, the time is saved, 4) the roller die can be worn and reprocessed, 5) the integral type roller has the same axial size, the number of the processed wires is more than that of the sleeved type roller (the sleeved combination type roller is generally composed of multiple sections, and the number of the processed wires is correspondingly reduced), so the production efficiency of the integral type roller is high.
