Automatic lubricating powder recovery device

Abstract

The invention discloses an automatic lubricating powder recovery device which comprises a lubricating powder recovery cylinder, a valve body and a valve clack, wherein the two ends of the lubricating powder recovery cylinder are provided with a through hole allowing a steel bar to penetrate therethrough; the bottom of the lubricating powder recovery cylinder is communicated with an opening at theupper end of the valve body; the upper part of the inner side of the valve body is provided with a powder discharge hole communicated with the lubricating powder recovery cylinder as well as a valve clack for opening/closing the powder discharge hole; and the lower part of the inner side of the valve body is provided with an air inlet and a powder discharge port, wherein the air inlet is connected with an air source, and the powder discharge port is communicated with a lubricating powder device. The automatic lubricating powder recovery devicedisclosed by the invention overcomes the shortcomings of the prior art, avoids flying of the lubricating powder in the production line of rolled steel bar, purifies the operation environment, guarantees health of operators, can recover the lubricating powder, saves resources and protects the production equipment perfectly. The automatic lubricating powder recovery device disclosed by the invention has the advantages of simple structure, low processing cost and the like, and is simple and easy to operate and convenient to maintain.

Description

Technical field [0001] The invention relates to an automatic recovery device for lubricating powder, in particular to an automatic recovery device for lubricating powder in the production of rolled steel bars. Background technique [0002] In the prior art, special processing techniques are required before cold rolling or drawing of steel bars. For example, cold-rolled ribbed steel bars need to be dephosphorized and coated with lubricating powder. The dephosphorized steel bars need to travel a certain distance after passing through the lubricating powder device. Then enter the rolling and drawing process. The purpose of the upper lubricating powder process is to facilitate the smooth progress of the next rolling and drawing process; the purpose of the steel bar walking for a certain distance through the lubricating powder device is: First, it is convenient for the steel bar to have sufficient time for the impurities on it to fall off, and to better protect the rolling , Drawing ...

AI Technical Summary

Problems solved by technology

[0003] The existing technology has the following defects: before the steel bar passes through the lubricating powder device and enters the rolling and drawing process, there is no device to process the falling lubricating powder during the walking distance of the steel bar, and the lubricating dust is seriously flying, which not only pollutes the Operating environment, endangering the health of operators, and causing waste of lubricant powder
