A kind of high-efficiency chopping mechanism and chopping method

Abstract

The invention discloses an efficient tooth cutting mechanism. The efficient tooth cutting mechanism comprises a cutting knife, a clamping device for clamping the cutting knife, a screw rod penetratingthrough a bracket, and a first straight line driving mechanism, wherein the cutting knife is vertically down, the clamping device is fixedly connected with a cutting tooth sliding sleeper, the bracket is arranged above the cutting tooth sliding sleeper, a nut is arranged on the top of the bracket, the screw rod penetrates through the nut, the bottom end of the screw rod is connected to a pressingplate located in the bracket, a spring is arranged between the top of the cutting tooth sliding sleeper and the bottom of the pressing plate, and the first straight line driving mechanism is used fordriving the upper and lower movement of the cutting tooth sliding sleeper. According to the efficient tooth cutting mechanism and a tooth cutting method, the problems that in the prior art, a tooth cutting machine often needs to stop to make recovery and has low work efficiency, meanwhile the working pressure is high, and durability is low are solved; and the purposes that stopping for making recovery is not needed, the work efficiency is improved, meanwhile the service stability is improved, and the service life is prolonged are realized.

Description

technical field

[0001] The invention relates to the field of file processing, in particular to an efficient tooth chopping mechanism and a tooth chopping method. Background technique

[0002] Chopping is a process used to make files. On the working surface of the steel file body made of steel rolled into various shapes of file blanks, numerous sharp edge lines are regularly chopped along the axial direction. The original file chopping teeth was manually chiseled with a small flat-mouthed chisel, and in modern times, a gear chopping machine is used for mechanical chopping. The file with chopped teeth is heat-treated and can be used after reaching the required hardness. There is a lot of noise when chopping teeth with a gear cutter. In the prior art, there are tooth chopping mechanisms that rely on pneumatic or hydraulic pressure as power. This type of tooth chopping mechanism is directly connected to the tooth chopping ram mechanism and the chopping knife by the cylinder o...
