[CN 202210575004.7] Intelligent press with built-in deformation compensation module
[CN 202210575004.7] An intelligent press with a built-in deformation compensation module Title: An intelligent press with a built-in deformation compensation module Application number: CN 202210575004.7 Applicant: Huazhong University of Science and Technology Application date: 2022-5-25 Patent type: Invention application The present invention provides an intelligent press with a built-in deformation compensation module, which belongs to the field of presses and includes a press body, a deformation compensation module and a control module, the main body of the press is used for forming the sample to be formed. In the deformation compensation module, the laser transmitter is connected with the optical fiber sensor to transmit pulse signals to it. The optical fiber sensor is arranged on the pre-tightening pull rod of the press body and generates reflected light signals. The optical signal processor is used to process the reflected light signals to measure the strain information of the pre-tightening pull rod, then, the deformation of the fuselage is compensated. By obtaining the actual depression amount of the upper slider to compensate for the deformation of the fuselage, the invention can effectively solve the problem of the deformation of the fuselage caused by the force and impact load of the existing hydraulic press during the working process, and the change of the pre-tightening force of the pre-tightening tie rod caused by the slider The problem of insufficient stroke measurement accuracy.
