Shaping device of crocheting apparatus

Abstract

A crochet machine forming device, comprising a base, a hollow mandrel, a hollow forming head and a drive shaft; the mandrel is fixedly connected to the mandrel hole of the base, the drive shaft is dynamically connected to the drive shaft hole of the base, and the forming The head is plugged on the top of the mandrel and the top surface is a concave-convex surface; the above-mentioned mandrel is provided with an outer shaft, and a combined cam and an inner sleeve shaft are arranged between the mandrel and the outer shaft. The combined cam and the inner sleeve shaft are adjustable and connected, and the inner sleeve The shaft and the outer shaft are adjustable, and the cylindrical surface of the above-mentioned forming head and the cylindrical surface of the upper part of the mandrel are uniformly provided with axial grooves, and each axial groove of the forming head and the mandrel shaft below the axial groove A crochet needle is arranged in the slot, and the butt of the crochet needle is fixed on the combination cam; gears are respectively arranged on the transmission shaft and the outer shaft. When the metal wire passes through the forming head and the traction force is greater than the yield strength of the metal wire, the invention makes the mesh shape, and the softness and elasticity of the processed metal mesh pipe are greatly improved due to the existence of the mesh.

Description

technical field [0001] The present invention relates to a forming device for a crochet machine. Background technique [0002] Chinese patent No. 02264035.5 utility model patent specification discloses a liner, which is a high temperature resistant insulating liner, with a glass fiber flexible main casing and a stainless steel elastic mesh tube-shaped skeleton arranged in the main casing. At present, similar metal mesh pipes are generally made by weaving machines. Because the weaving wires of the mesh pipes are dense, the weight of the metal wires per unit area of ​​the metal mesh pipes is large, which not only consumes materials, but also has high costs, and the strength of the metal mesh pipes is relatively high. , the softness and elasticity are not ideal, and the axial elasticity is even worse. If the weaving thread of the network pipe can be made sparser, that is, there is a mesh, the existence of the mesh can make the network pipe have a certain space for expansion and...

AI Technical Summary

Problems solved by technology

Because the metal wire has a certain strength, the current crochet machine can only be used for the crochet of fiber fabrics, so it is not suitable for the crochet of metal wire
