Knife rest structure of pneumatic plate shearing machine

Abstract

The invention discloses a tool holder structure of a pneumatic shearing machine, comprising a coupling (1), a transmission shaft (2), a support block (3), a bracket (4), a crank (5), a connecting rod (6), Tool holder (7), scissors (8), slider (9), cylindrical guide rail (10) and protective sleeve (13); a transmission shaft is provided on one side of the coupling, and the transmission shaft runs through the coupling, The shaft coupling is compatible with the transmission shaft, and the transmission shaft is fixed on the bracket through the support block. A protective sleeve is installed in the support block, and the protection sleeve is adapted to the transmission shaft; a crank is arranged inside the coupling, and the crank The connecting rod is connected with the knife rest, and scissors are arranged on the knife rest, and the knife rest is installed on the slide block, and the slide block is plugged into the guide rail. The invention can absorb the reaction force produced by the anvil roller on the scissors, and the protective sleeve is installed so that the transmission shaft and the support block will not generate friction, thereby improving the service life of the scissors and the transmission shaft.

Description

technical field [0001] The invention relates to the field of mechanical technology, and in particular to a pneumatic shearing machine tool holder structure. Background technique [0002] The shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to the other blade to cut the plate. It uses the moving upper blade and the fixed lower blade to apply shearing force to metal sheets of various thicknesses with a reasonable blade gap, so that the sheets are broken and separated according to the required size. The shearing machine is a kind of forging machinery, and its main function is the metal processing industry. The products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electric power, electrical appliances, decoration and other industries to provide the required special machinery and complete sets of equipment. When the existing shearing machine is shearing, the an...

AI Technical Summary

Problems solved by technology

When the existing shearing machine is shearing, the anvil roller will produce a reaction force on the scissors, which will affect the service life of the scissors. The part of the transmission shaft inside the support block will wear out due to the friction force for a long time, which will affect the use of the transmission shaft. life
