New doubling drum and its manufacturing process

Abstract

The invention relates to doubling process step equipment in spinning machinery and particularly relates to a novel doubling groove drum and a manufacturing process thereof. The existing superplastic alloy groove drum has the defects that the superplastic alloy groove drum has poor gas bulging forming effect, and is less prone to gas bulging forming, a chromium coating on the surface of the groove drum is thin, has bubbles and is easy to peel off, the surface roughness is not smooth, the material impact toughness is poor, the superplastic alloy groove drum can not ensure that a groove curve and edge angles can not be formed according to stipulations, the routing in a doubling state is inconsistent and bent, a sliver has more pilling and hair feather, a spider web becomes wide and shows crescent type overlap / a small spider web occurs frequently, the groove drum can vibrate under high-speed operation conditions, and the routing is not fast. The invention provides the novel doubling groove drum and the manufacturing process thereof, and the structure can improve a traditional smelting process and overcome the defects of the existing superplastic alloy groove drum by optimizing the groove curve on a groove drum body, and adding a trace misch metal element component in the manufacturing process.

Description

technical field [0001] The invention relates to the equipment used in the yarn doubling process in textile machinery, in particular to a new yarn doubling groove drum and its manufacturing process. Background technique [0002] The groove drum is a necessary key part of the equipment in the yarn doubling process of textile enterprises. It has a complex structure and advanced technology. In particular, it adopts a superplastic alloy groove drum formed by one-time inflation. The groove drum body has two sets of parallel grooves and two sets of jumping slots. , two sets of groove slopes, two sets of corners, and an inflection point at both ends of the cylinder. The existing superplastic alloy tanks have the following defects in use: 1. Inconsistent yarn alignment, bending, evenness, pilling and many hairiness in the doubling state; 2. Cobwebs become wider and crescent-shaped overlapping / fine cobwebs appear frequently; 3. . The groove drum will vibrate and the wires will not ru...

AI Technical Summary

Problems solved by technology

The existing superplastic alloy tanks have the following defects in use: 1. Inconsistent yarn alignment, bending, evenness, pilling and many hairiness in the doubling state; 2. Cobwebs become wider and crescent-shaped overlapping / fine cobwebs appear frequently; 3. .The defect that the tank will vibrate and the line is not fast under the condition of high-speed operation

The following defects exist in the manufacturing process: 1. Inflatable molding effect is poor, the cylinder body cracks, shrinks, groove curves and edges and corners are not in place, and the mouth of the forming mold leaks, etc.; , there are bubbles, easy to peel off, the surface roughness is not smooth, and the impact toughness of the material is poor; 3. It is not guaranteed that the groove curve and edges are formed according to the regulations
