Abstract
The invention discloses automatic test equipment for shearing force of a pair of scissors, which is characterized by comprising a hydraulic machine, a fixture used for fixing tested scissors, a servo motor used for conveying materials for test and a control system, wherein an oil cylinder connected with the hydraulic machine is arranged above the fixture, and the output end of the oil cylinder is arranged above the tested scissors. The invention provides the equipment which is intelligent and automatic and can accurately record the sharpness of blades, real-time shearing force, maximal shearing force and average shearing force can be displayed by a PLC program on a liquid crystal touch screen, and a curve chart can be finally formed to precisely record the actual shearing and cutting force of the blades. The automatic test equipment can carry out precision evaluation on the shearing performance of the scissors, so as to provide powerful data support for performance improvement of the blades.
Description
Technical field
The present invention relates to a kind of automated test device of knife pressure, be specifically related to the automatic intelligent testing apparatus of a kind of family, city sites greening professional scissor shearing force, belong to graden machine, technical field of tools.
