Thread machining tool for graphite electrode

Abstract

The invention discloses a thread machining tool for a graphite electrode. The thread machining tool comprises a tool body, wherein a cutter holder body and a connection block are fixed to the two sides of the top end of the tool body separately; a chuck is connected to the left side of the connection block; a cutter opposite to the chuck is connected to the right side of the cutter holder body; aslide seat is fixed to the left side of the top end of the tool body; a dust collection cover is arranged above the slide seat; a first absorption window is formed in the side surface of the dust collection cover; the right end of the cutter penetrates through and stretches into the dust collection cover; a charge hole is formed in the middle part of the right side of the dust collection cover; arubber ring is fixed to the charge hole; rectangular slide blocks are fixedly connected to the two sides of the bottom end of the dust collection cover separately; the two rectangular slide blocks both stretch into the slide seat; and two rectangular slide grooves matched with the rectangular slide blocks are formed in the top end of the slide seat. The thread machining tool disclosed by the invention is provided with a dust collection mechanism, and is reasonable in design, and capable of realizing collection treatment for dust in a machining process; and meanwhile, the thread machining tooldisclosed by the invention is provided with a protection mechanism, and is capable of effectively protecting the safety of workers.

Description

technical field [0001] The invention relates to the technical field of graphite electrode processing equipment, in particular to a graphite electrode thread processing machine tool. Background technique [0002] Graphite electrode refers to petroleum coke, pitch coke as aggregate, coal tar pitch as binder, a kind of resistant electrode made by calcination of raw materials, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization and mechanical processing. High temperature graphite conductive material. At present, domestically produced graphite electrodes are formed by high-temperature graphitization of carbon rods in a graphitization kiln. After graphitization to form graphite electrodes, threads need to be processed on a thread processing machine. Since the thread is formed under the action of high-speed rotation of the tool, a large amount of graphite dust will appear during the processing, which not only causes serious pollution to the w...

Problems solved by technology

[0005] The purpose of the present invention is to provide a graphite electrode thread processing machine tool, equipped with a dust collection mechanism, and the design is reasonable, can realize the collection and treatment of dust in the processing process, and at the same time has the advantages of a protection mechanism, which can effectively protect the safety of workers, and solve the problem of existing devices. The unreasonable setting of the dust collection room will affect the normal processing of the machine tool, and the lack of protection mechanism will easily cause workers to be injured
