Continuous graphite dip-coating machining mechanism for hard alloy parts

Abstract

The invention discloses a continuous graphite dip-coating processing mechanism for hard alloy parts, which relates to the technical field of hard alloy processing and comprises a dip-coating box and a dip-coating processing disc. The dip-coating machining disc is rotationally arranged on the inner side of the dip-coating box, blank notches are formed in the circumferential side of the dip-coating machining disc at equal angles, a bearing mechanism matched with the dip-coating machining disc is arranged at the position, located at the bottom of the dip-coating machining disc, of the inner side of the dip-coating box, and a bearing net belt and a driving unit are rotationally arranged on the bearing mechanism. The driving unit is used for driving the bearing net belt and the dip-coating machining disc to rotate synchronously, and through the arrangement of the bearing frame and the bearing net belt, when the bearing net belt bears a hard alloy blank, the driving unit drives the rotating roller to drive the bearing net belt and the dip-coating machining disc to rotate synchronously; therefore, the hard alloy blanks in the blank notches are kept in a relatively static state, and friction damage to the edges of the hard alloy blanks in the blank notches during dip-coating machining disc rotation is prevented.

Description

technical field [0001] The invention relates to the technical field of cemented carbide processing, in particular to a cemented carbide blank graphite dip coating processing device. Background technique [0002] It is well known that cemented carbide is an alloy material made of a hard compound of a refractory metal and a bonding metal through a powder metallurgy process. It has high hardness, strength, wear resistance and corrosion resistance. For "industrial teeth", it is used to manufacture cutting tools, knives, cobalt tools and wear-resistant parts, and is widely used in military industry, aerospace, machining, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields. In the production and processing of cemented carbide, a billet close to the shape of the workpiece is first made by powder metallurgy, and then sintered. Before the gold is sintered, a layer of liquid graphite needs to be painted on the outer surface of the cemented ...

Problems solved by technology

[0004] When the applicant is actually using it, by arranging the cemented carbide blanks in the placement box, and then making the placement box immersed in the liquid graphite in the ink brush box, batches of graphite dipping processing are realized, although compared with the traditional manual Brushing ink improves work efficiency, but it is cumbersome to take and place cemented carbide blanks in the storage box, and continuous flow operation cannot be realized. When performing continuous flow operation, a disc rotating part needs to be installed in the ink brush box. An opening is opened on the disc rotating part to store cemented carbide blanks to realize circular rotating loading and unloading, and when the bottom of the disc rotating part needs to be provided with an arc-shaped bracket that matches it, so as to realize When the opening on the rotating part rotates downwards, it prevents the carbide blank from falling inside the opening. At that time, when the disc rotating part rotates, the carbide blank will rub against the arc bracket, which will cause the carbide Blank edge damage affects the quality of cemented carbide blanks
