Method for producing roller body of high precision compound guiding cloth guide roller

Abstract

The invention discloses to a manufacturing method for a high-precision composite cloth guide roller body which relates to the technological field of textile, plastic, paper making and leather making, and the like, and more particularly relates to the technological field of textile printing and dyeing equipment. The invention comprises the following steps: a stainless steel external roller body and a cold rolled sheet roller body are rolled and welded respectively to form a stainless steel external roll blank and a cold rolled sheet roll blank; the cold rolled sheet roll blank is sheathed in the stainless steel external roll blank to make a double layer roll blank, and the spin-drawn forming is carried out at last. The method is the manufacturing method for the composite cloth guide roller body with good quality, reliable performance, low energy storage and high precision.

Description

technical field [0001] The invention relates to the technical fields of textiles, plastics, papermaking, leather making, etc., and in particular to the technical field of textile printing and dyeing equipment. Background technique [0002] In the textile printing and dyeing industry, the fabric guide roller is a key component to ensure that the high-grade fabric is transported and guided without wrinkles. In the domestic printing and dyeing machinery and equipment, composite stainless steel cloth guide rollers made of traditional handicraft reels are commonly used so far. The quality is low, the weight of the roller is high, and the energy storage is high. Compared with developed countries, there is a certain gap. The composite cloth guide roller body is made of double layers of different metal materials. The outer layer is rolled with stainless steel plate and the seam is welded. The inner layer is rolled with cold plate and the seam is not welded. The inner and outer layer...

AI Technical Summary

Problems solved by technology

[0004] 1. The clamping of the wheel bed Huff tire mold can easily lead to expansion of the mold body, loss of roundness and taper of the roller body

Manual tightening of several bolts or hydraulic fastening and mold clamping, manual tightening lacks the consistency of applied force, and hydraulic tightening lacks self-locking properties. The roller body in the tire mold is affected by the expansion force when it is spun It is easy to produce defects such as Huff gap taper and expansion joint ellipse

[0005] 2. Spinning by the elastic head of the lathe bed, the axial feed of the lathe rod while the workpiece does not move, resulting in a single side wall thickness of the roller body and poor straightness

[0006] 3. The inner layer of the double-layer roller is not welded, and the thermal expansion is deformed on one side, which weakens the bending strength

This structure seems to improve the strength of the roller body, but it is actually strong on the outside and dry in the middle. When used at high temperature, due to the existence of hidden dangers in the outer layer of inner layer cracks, the thermal expansion force of the inner layer is directly squeezed and released at the cracks, resulting in weak parts of the outer layer of the roller. The strength of one side is weakened, and the roll body is deformed

[0007] Due to the existence of the above defects, the improvement of the technical performance of domestic textile printing and dyeing high-end equipment is restricted, and it is difficult to meet the quality requirements of processing high-grade printing and dyeing products
