Coking-removing die box of drawing machine

Abstract

The invention relates to a coking-removing die box of a drawing machine. The coking-removing die box comprises a lubricator box body and a die box body, wherein the die box body is internally provided with a wiredrawing die; a stirrer device is arranged on the lubricator box body and comprises a stirring shaft which can be rotatably arranged on the lubricator box body; the stirring shaft is connected with a stirring gear and is provided with an axial wire feeding hole; the inner end of the stirring shaft stretches into the lubricator box body and is provided with a stirring rod; and a blade is fixed on the front end of the stirring rod, stretches into and is matched with a lubrication taper hole which is arranged in the front of a wire feeding end of the wiredrawing die. In the invention, the stirrer device is arranged on the lubricator box body, and the blade which is fixed on the stirring shaft of the stirrer device can be used for scraping coking at the inlet of the wiredrawing die to ensure the reliability in lubrication.

Description

technical field [0001] The invention relates to a mold box of a wire drawing machine, in particular to a decoking mold box of a wire drawing machine. Background technique [0002] The metal wire drawing machine belongs to the pre-processing equipment for the production of metal products. Its function is to draw the wire or bar through the wire drawing machine, so that the diameter, roundness, internal metallographic structure, surface finish and straightness of the wire or bar are all improved. Meet the requirements. The wire drawing machine mold box is used to fix the wire drawing die and provide lubricating powder. [0003] Such as figure 1 As shown, it is a commonly used dry-type wire drawing machine mold box at present, which includes a lubricating box body 22 and a mold box body 16. Lubricating powder 7 is housed in the lubricating box body 22, cooling water 10 is housed in the mold box body 16, and the wire drawing die 15 is installed in the mold box body 16. The s...

AI Technical Summary

Problems solved by technology

The mold box of the wire drawing machine has the following defects: the lubricating powder is easy to coke at the conical hole of the wire drawing die inlet, thereby scraping off the lubricating carrier (coating) on ​​the surface of the steel wire, preventing the wire from carrying powder, resulting in failure of lubrication, resulting in bright wire and shrinkage; Driven by the steel wire, the lubricating powder keeps piling forward, so that the steel wire behind is exposed without powder coverage, which affects the lubrication effect. It is necessary to manually stir the lubricating powder evenly at regular intervals, making the product quality unstable and uncertain.
