Abstract

The invention discloses a special type knife with higher processing efficiency and preciseness. The special type knife comprises a knife handle, a knife seat is arranged on the knife handle, the upper part of the knife seat is a semicircular knife pedestal, two sides of the top of the knife pedestal are respectively provided with end and side knife blades, the knife handle and the knife seat are internally provided with emplacement holes which are communicated mutually, inner bore cutters penetrate through the emplacement holes, the wall of the knife handle is provided with a threaded hole communicated with the emplacement holes, and the threaded hole is provided with a lock bolt. In the invention, processing inner bores, inner bore cutters of valve line, end and lateral knife blades of processing ends and sides are integrated, thus machine-shaping the inner bores and of end, side and middle part of the upper part of the valve in one step, shortening processing time, improving processing efficiency, saving processing cost and improving processing preciseness.

Description

Technical field [0001] The invention relates to a tool, in particular to a special tool for processing valve bodies of flap type oxygen cylinder valves and shaft coupling type hydrogen cylinder valves. Background technique [0002] At present, when processing the inner hole and valve body of the oxygen cylinder valve body and the upper end surface and side surface, two to three template knives are usually used to complete the processing in two to three steps. This method not only increases the processing steps, reduces the processing efficiency, and increases the processing cost; at the same time, due to the complexity of processing the oxygen (hydrogen) cylinder valve body, the step-by-step processing will affect the entire oxygen (hydrogen) cylinder valve The machining accuracy of the valve body. In addition, the inner hole cutter used to process the inner hole and the valve line is usually made of high-speed steel, and its cutting force is much higher than that of the inner h...
