A liquid lubricated wire drawing device

Abstract

The invention discloses a liquid lubricated wire drawing device, which comprises a tank body, a wire reel, a guide roller, a wire brush, a dryer, a mould, a dehumidifier and a controller. The wire reel is arranged on the left and right sides of the outer wall of the tank At the upper end, the mold is fixed at the bottom of the first cavity, the dehumidifier includes a third fan and a fourth air pipe, several wire brushes are fixed at the bottom of the third cavity, and the dryer includes The second fan, the bellows, the second air pipe and the third air pipe, one end of the wire to be processed is fixed on the wire reel on one side, and the other end passes through it successively after being guided by several guide rollers fixed in the tank. The mould, dehumidifier, wire brush and dryer are connected to the wire reel on the other side, and the wire rod is thinned through the mold immersed in the lubricating liquid to fully ensure the lubrication effect; the wire rod enters the third cavity through the dehumidifier Before cleaning inside the body, part of the lubricating fluid is blown off in advance to improve the subsequent cleaning effect.

Description

【Technical field】 [0001] The invention relates to the technical field of wire drawing, in particular to the technical field of a liquid lubricated wire drawing device. 【Background technique】 [0002] The production steps of bolts generally include annealing, pickling, wire drawing, forming, grinding, heat treatment and surface treatment. In the wire drawing process, people use a wire drawing machine to cold-draw thicker metal wires to the required wire diameter after pickling. When the metal wire passes through the wire drawing die, the friction force will cause the temperature of the interface of the wire drawing die to rise rapidly, so it is necessary to use a lubricating liquid for lubrication and cooling during the metal wire drawing process. There are two ways to add lubricating liquid, one is to spray the wire drawing die and metal wire from high to low, and there is a problem that the lubricating liquid is difficult to reach the film hole of the wire drawing die, whi...

AI Technical Summary

Problems solved by technology

There are two ways to add lubricating liquid, one is to spray the wire drawing die and metal wire from high to low, and there is a problem that the lubricating liquid is difficult to reach the film hole of the wire drawing die, while the other is to directly spray High-pressure and high-speed lubricating liquid is injected into the die hole through the nozzle, forcing the lubricating liquid to enter the interface area, but there are problems such as complex structure, high maintenance cost, and easy dripping and overflowing of the lubricating liquid from the workbench

The temperature of the lubricating fluid flowing back into the lubricating fluid tank will gradually increase after a period of continuous use, thereby weakening the cooling effect on the metal wire.

In addition, after wire drawing, the metal wire with lubricating fluid is prone to slipping in the subsequent process, which affects the quality of the bolts, which needs to be solved urgently
