Planet rolling step pulley of water tank wire-drawing machine

Abstract

The invention relates to wire-drawing production equipment in wire product industry, in particular to a drawing step pulley of a water tank wire-drawing machine. The drawing step pulley comprises pulley plates, a planet wheel, a planet wheel shaft, a chafing plate and a planet rolling step pulley of water tank wire-drawing machine assembled by the plurality of pulley plates. The invention provides a planet rolling step pulley, which has a counter pull drawing effect and avoids a wire sliding on the planet rolling step pulley. Breaking a principle that the size of a drawing force used in wire drawing is determined by the size of a friction force between the wire and the step pulley, the planet rolling step pulley allows the size of the drawing force to be determined by the size of the friction torque of the planet wheel and the number of the planet wheel, and allows the planet wheel to rotate freely when the wire slide back on the planet rolling step pulley, thereby avoiding the sliding friction of the wire on the step pulley and converting the power consumption for sliding friction into rolling friction torque to do work. The planet rolling step pulley can obviously reduce energy consumption for drawing and effectively solve the problem of step pulley wear and wire chafing.

Description

Technical field: [0001] The invention relates to wire drawing production equipment in the wire product industry, in particular to a drawing cone of a water tank wire drawing machine. Background technique: [0002] At present, the drawing tower pulleys of water tank wire drawing machines in the wire product industry are generally cast steel (iron) wheel bodies. When drawing the wire, there is always relative sliding between the wire and the tower pulley, which leads to adhesive wear and abrasive wear, which leads to the wear and tear of the tower pulley (rework), increases the energy consumption of drawing, wears the surface of the wire rod, and damages the lubrication of the wire rod layer, reducing the service life of the abrasive tool, and in severe cases, the phenomenon of whitening and cracking will occur, making drawing impossible. [0003] In order to improve the sliding state between the wire and the cone wheel and prolong the service life of the cone wheel, chromium...
