Pressure reduction and dust prevention mold for metal bar processing

Abstract

The invention discloses a pressure reduction and dust prevention mold for metal bar processing in the technical field of metal bar processing. The pressure reduction and dust prevention mold for metalbar processing comprises a lower base plate. A dustproof cover is fixedly arranged on the top of the lower base plate. A matched brush piece is attached to the position, close to the left side, of the top of a lower mold plate. The top of the brush piece is provided with a connecting host communicating with the brush piece. A rack matched with a gear is arranged at the bottom of a movable guide rod. According to the pressure reduction and dust prevention mold for metal bar processing, a negative pressure fan in a dust removal part generates negative pressure at a through hole through the connecting hose and then discharges dust in the dustproof cover to a PTFE coated filter material in the dust collection box to achieve the pressure reduction and dust suction and collection functions. Meanwhile, the pressure reduction and dust prevention mold is provided with the movable guide rod, a guide sleeve, the gear, a servo motor, a limiting block II and a preset spring, drives the movable guide rod to do left-right reciprocating movement through cooperation of the servo motor, the gear and the rack, then drives the brush piece to do left-right reciprocating movement, removes stubborn dustleft on the lower mold plate through contact between bristles and the lower mold plate and improves the cleaning quality.

Description

technical field [0001] The invention relates to the technical field of metal bar processing, in particular to a decompression and dust-proof mold for metal bar processing. Background technique [0002] Traditional metal rods are used in the processing of molds. Dust easily enters the surface of the mold during use, resulting in residual dust on the surface of the workpiece after processing, which is poor in practicability. At the same time, some stubborn dust will adhere to the lower template, making it difficult to clean. It is troublesome, so we propose a decompression and dust-proof mold for metal rod processing. Contents of the invention [0003] The object of the present invention is to provide a decompression and dust-proof mold for processing metal rods, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a decompression and ...
