Planet rolling intermediate winding drum of wire drawing machine

Abstract

The invention relates to wire drawing production equipment of the wire product industry, in particular to a straight line type wire drawing machine, a loop type wire drawing machine and a pulley typecontinuous wire drawing machine. The wire drawing production equipment comprises a planet rolling intermediate winding drum of the wire drawing machine, which is assembled by a drawing wheel, a planetary wheel, a planetary wheel shaft, a chafing slice and a compression ring. The invention provides the planet rolling intermediate winding drum of the wire drawing machine, which has the effect of back pull drawing. The planet rolling intermediate winding drum of the wire drawing machine can eliminate an automatic speed regulation system with the complicated and expensive intermediate winding drumand obviously reduce equipment cost when used in the straight line type wire drawing machine and the loop type wire drawing machine; and the planet intermediate winding drum can make the pulley typecontinuous wire drawing machine have the property characteristics of the straight line type wire drawing machine and has obvious effect of back pull drawing when used as the intermediate winding drumof the pulley type continuous wire drawing machine. The magnitude of a drawing force of the planet rolling intermediate winding drum is determined by friction moment and the quantity of the planetarywheel; and when the wire slides off on the planet rolling intermediate winding drum, the planetary wheel can freely rotate and apply work by using the rolling friction moment of the planetary wheel. The wire drawing production equipment can obviously reduce drawing energy consumption, prolong the service life of grinding tools, and effectively solve the problem of scratching wires.

Description

technical field [0001] The invention relates to wire drawing production equipment in the wire product industry, in particular to an intermediate reel of a linear, looper and pulley continuous wire drawing machine. Background technique [0002] Linear and looper wire drawing machines are relatively advanced wire drawing production equipment in the world. The steel wire is almost straight from one reel to another, which is very suitable for continuous drawing of thick steel wire (Φ7-Φ18), high-strength steel wire (1200-1300Mpa) and special-shaped steel wire. When the linear and looper wire drawing machines are drawing, there is a reverse tension between the front and rear reels, which can significantly reduce the drawing energy consumption and prolong the service life of the abrasive tool. There is no sharp bending and axial torsion of the steel wire during the drawing process, so the performance of the finished product is better. However, the linear and loop-type wire drawi...

Problems solved by technology

In order to meet this requirement, the linear and loop-type wire drawing machines must be equipped with a very complicated electrical control system and speed regulating mechanism. The operation must have a considerable technical level, and the maintenance is not easy to master. At the same time, the equipment cost is too high

[0003] The pulley type continuous wire drawing machine has the advantages of simple structure, less investment, convenient operation, and simple management, etc., but the steel wire is prone to axial torsion during the drawing process, which affects the quality of the drawn product, and is not suitable for drawing high-strength steel wire. With the function of anti-pull pulling
