Drawbench cooling device with rust preventing and incrustation removing functions

Abstract

The invention discloses a drawbench cooling device with the rust preventing and incrustation removing functions. A drawbench comprises a coiling block and a cooling ring. The cooling ring is sleeved with the coiling block. An annular sealing cavity is formed by the coiling block and the cooling ring. The cooling device is arranged in the cooling ring. The cooling device comprises a water inlet pipe, a hollow shaft, a first communication block, a second communication block and a switchover mechanism. One end of the first communication block is communicated with the upper portion of the annular sealing cavity through a first connecting pipe, and the other end of the first communication block is communicated with the hollow shaft through a second connecting pipe. One end of the second communication block is communicated with the lower portion of the sealing cavity through a third connecting pipe, and the other end of the second communication block is communicated with the hollow shaft through a fourth connecting pipe. The water inlet pipe comprises a first water inlet and a second water inlet which are different in height, and a Teflon coating layer is arranged on the whole inner surface of the annular sealing cavity. The problems of incrustation and rusting of the cooling device are solved, and the drawbench cooling device is good in using effect and high in practicability.

Description

technical field [0001] The invention relates to the technical field of wire drawing machines, in particular to a cooling device for a wire drawing machine with functions of rust prevention and descaling. Background technique [0002] With the increase of the running speed of the wire drawing machine, nearly 90% of the heat generated during wire drawing is carried to the reel by the steel wire, and a very small part is transmitted to the wire drawing die. The cooling effect of the reel has increasingly become a key factor affecting the drawing speed and the quality of the steel wire after drawing. [0003] At present, the reel of the wire drawing machine is generally cooled by narrow slit water, but this cooling method is prone to problems such as scaling and rusting on the reel. The main measures and disadvantages are as follows: 1), the silver powder paint spraying method can not solve the scale problem, and because the wire drawing machine is in a long-term drawing workin...

Problems solved by technology

[0003] At present, the reel of the wire drawing machine is generally cooled by narrow slit water, but this cooling method is prone to problems such as scaling and rusting on the reel

The main measures and disadvantages are as follows: 1), the silver powder paint spraying method can not solve the scale problem, and because the wire drawing machine is in a long-term drawing working state, the silver powder paint is in a repeated high and low temperature state, which is easy to age. Eventually, the paint layer will peel off, and the cooling system will be blocked with scale

2) The use of nickel plating can solve the problems of rust and coating peeling off, but it cannot solve the problem of scaling, and the processing cost is relatively high

3) The scale cleaning of the drawing equipment is often carried out regularly. First, the labor cost increases, and second, the production progress of steel wire drawing is delayed.
