AI Technical Summary

Technical Problem

Existing sandwich panel cutting equipment lacks the ability to perceive minute dynamic deformations of the board material in real time during processing, which leads to positional deviations during cutting. Furthermore, it lacks precision in controlling the strategic clamping force, resulting in chipped edges and dimensional deviations during cutting, thus affecting processing accuracy and yield.

Method used

The clamping structure employs multi-cylinder collaborative positioning, combined with an elastic displacement detection component. It accurately determines the elastic characteristics of the sheet metal through the force-displacement change curve, dynamically matches and adjusts the clamping force range in real time, and combines targeted fine-tuning for local deformation to achieve precise differentiation between workpiece dynamic deformation and tool path offset. It adopts a closed-loop control throughout the entire process, including parameter initialization, clamping stabilization, cutting control, and correction optimization.

Benefits of technology

It improves the equipment's adaptability to sandwich panels of different materials and thicknesses and enhances clamping reliability, avoiding panel deformation or displacement caused by improper clamping force, achieving high-precision processing results, meeting the needs of large-scale processing, extending equipment lifespan, and improving the cleanliness of the processing environment.

Abstract

This invention belongs to the technical field of sheet metal processing equipment, specifically relating to a sandwich panel cutting device with multi-cylinder collaborative positioning. It includes a worktable and a base, with an adjustment device on the base and a cutting device mounted on the adjustment device. A vertical clamping device is located below the cutting device. The vertical clamping device includes a cylinder mounting plate, a first cylinder, a first pressure plate, a third pressure plate, a third cylinder, a second cylinder, and a second pressure plate. An elastic displacement detection component is embedded inside the first pressure plate, contacting the workpiece. Side clamping devices are located on both sides of the workpiece. This invention achieves stable clamping effects through the linkage of the multi-cylinder collaborative clamping structure and the elastic displacement detection component embedded in the pressure plate, combined with the displacement-force change curve to accurately determine the elastic characteristics of the sheet metal, dynamically matching and real-time adjusting the clamping force range, and combining local deformation-targeted fine-tuning logic. This results in stable clamping effects at multiple points in both the vertical direction and on the sides.
