Abstract

The invention discloses a testing device and a testing method for the durability of a tube shear. The testing device for the durability of the tube shear comprises a tube shear clamp, a driving devicefor driving the tube shear to clamp or loosen, a tube conveying device for conveying tubes to the tube shear successively and a controller, wherein the driving device and the tube conveying device are both electrically connected with the controller. The testing method for the durability of the tube clamp comprises the following steps: S10: fixing the tube shear on the tube shear clamp and puttingthe tubes in the tube conveying device; S20: starting testing, and conveying the tubes in the tube shear by the tube conveying device; S30: driving a free handle by the driving device and enabling the tube shear to gradually clamp the tube until the tube is sheared off; S40: driving the free handle by the driving device and enabling the tube shear to loosen; S50: repeating S20 to S40 for severaltimes until preset test times are reached. The testing device and the testing method for the durability of the tube shear, disclosed by the invention, have the advantages that the durability of the tube shear can be automatically tested, so that manual operation can be effectively reduced and the test efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of workpiece testing, in particular to a pipe shear durability testing device and method. Background technique [0002] Pipe shears are a tool for cutting pipes, which is one of the necessary tools in pipe installation. Pipe scissors generally include fixed handles, movable handles and blades. In the process of cutting the pipe, it is necessary to hold the movable handle repeatedly, and drive the movable handle to repeat the action, so that the blade gradually clamps the pipe. After the cutting is finished, the movable handle can be split apart towards the direction away from the fixed handle. During the use of pipe shears, problems such as blade bluntness, chipping, curling, and pipe shear spring failure often occur. The quality of the pipe shears directly affects the installation effect of the pipe. Therefore, the durability of the pipe shears needs to be tested. Most of the traditional pipe shear test ...
