Slip ring type planet rolling drawing wheel

Abstract

The invention relates to a middle winding drum of a linear, dance or slip continuous wire drawing machine and a drawing wheel of a wet wire drawing machine in the wire rod product industry and provides a slip ring type planet rolling drawing wheel which has a counter pull drawing effect and is provided with a wire rod and a slip ring which are capable of freely rolling, slipping and withdrawing on a planet wheel as an integral whole. Used as the middle winding drum of the linear, dance or slip continuous wire drawing machine, the drawing wheel can meet the requirement for constant second volume of the drawing wire rod of each slip ring type planet rolling middle winding drum, thereby omitting an automatic speed regulation system of the linear or dance wire drawing machine and ensuring that the slip wire drawing machine has the performance characteristics of the linear wire drawing machine; Used as the drawing wheel of the wet wire drawing machine, the drawing wheel can be used for preventing relative sliding friction between the wire rod and the drawing wheel, preventing generation of rolling abrasion when the wire rod rolls on the planet wheel, generating the counter pull drawing effect and converting sliding friction power consumption into a rolling friction torque to do work, thereby further reducing the drawing energy consumption, improving the quality of the drawing wire rod and effectively solving the problem of drawing wheel abrasion.

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 straight-line type, a looper type, and a pulley type continuous wire drawing machine and a drawing tower pulley of a water tank wire drawing machine. Background technique: [0002] At present, the drawing tower wheels of the water tank wire drawing machine in the wire product industry are generally cast steel (cast 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 (repair) and wears the surface of the wire rod, destroys the wire lubricating layer, and increases the draw rate. Energy consumption will reduce the service life of the abrasive tool, and in severe cases, the phenomenon of whitening and cracking will occur, making the drawing impossible. [0003] I...

Problems solved by technology

However, during the implementation of the patent, the requirements for the planetary gear are relatively high, and when the wire slips on the planetary wheel, although the relative sliding friction with the cone wheel is avoided, the rolling wear caused by rolling on the planetary wheel cannot be avoided and the drawing The wire produces regular continuous axial microbends, which may have a certain impact on the quality of the drawn wire
