[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a positioning and guiding assembly above the positioning frame. The feed cylinder pushes the feed push plate to guide the plate into the open frame and enter the shearing position of the shearing machine frame. The feed amount acquisition device monitors the horizontal movement distance of the plate in real time to ensure that the plate accurately reaches the shearing position. The high-precision positioning capability helps to improve the shearing accuracy and thus reduce waste generation and improve material utilization. Automated feeding and positioning reduce the chance of manual contact with the plate and reduce the safety risks of workers during operation. The thrust, speed and parameters of the feed cylinder and the feed amount acquisition device can be adjusted to adapt to plates of different thicknesses, sizes and materials. The precise feeding and positioning of the positioning and guiding assembly helps to achieve stable quality control, can reduce dimensional inconsistencies or quality problems caused by position deviations, and ensure the consistency of the plate shearing process.

[0019] 2. The present invention installs a feed monitoring device on the front of the shearing machine frame. The feed monitoring device detects the shearing depth of the plate. When the monitoring results of the plate feed rate are consistent, the positioning lifting plate rises. The dual detection of the feed rate collection device and the feed monitoring device can monitor the position changes of the plate during the shearing process in real time and accurately, ensuring that the shearing length is highly consistent with the preset value, which helps to reduce errors and improve the processing accuracy and consistency of the product. The dual detection can timely discover and correct plate deviation or jamming, thereby maintaining the stability and continuity of the production process, helping to reduce the scrap rate, improve production efficiency and material utilization, avoid potential safety hazards, and thus improve safety performance in the shearing process.

[0020] 3. The present invention installs a contact sensor on the inner side of the installation trough. The feeding motor drives the plate placing plate to move so that the rear end of the plate passes through the inner side of the plate feeding port and moves in the direction of the plate introduction opening frame. The rear end of the plate is blocked by the positioning lifting plate after contacting the contact sensor. The flat alignment of the plate feeding end can ensure that the plate is in the correct position and angle before shearing, which helps to reduce deviations during the shearing process and ensure that the size and quality of the product meet the requirements. Automated loading and positioning alignment reduce the time and labor of manual operation, allowing the plate to enter the shearing position more quickly, thereby improving the overall production efficiency. The flat and aligned plates are more stable during the shearing process and are not prone to displacement or distortion, further improving the shearing accuracy of the plates.

[0021] 4. The present invention installs a conversion stabilizing seat at the telescopic end of the lifting and stabilizing hand bar. After the positioning and guiding assembly drives the plate into place, the lifting and stabilizing hand bar pushes the conversion stabilizing seat to move upward to support the plate, thereby ensuring the stability of the plate on the fixed load-bearing platform. It prevents the plate from shaking when the positioning and guiding assembly is reset, thereby preventing the continuous operation of the positioning and guiding assembly from being adversely affected. After the positioning and guiding assembly is reset, the conversion stabilizing seat moves downward to allow the plate to be smoothly loaded onto the fixed load-bearing platform. The plate is accurately positioned and firmly supported before processing, thereby reducing processing errors caused by shaking or offset of the plate, and helping to improve the accuracy of subsequent processing steps such as shearing, drilling, and cutting.
