A thin steel sheet clamping and tensioning device and a method for clamping and tensioning a thin steel sheet

Abstract

The invention relates to a thin steel sheet clamping and tensioning device and a method for clamping and tensioning a thin steel sheet. The thin steel sheet clamping and tensioning device comprises a right clamp, wherein the clamp comprises a U-shaped air bag groove (1), an L-shaped movable clamping strip (2), a large air bag (3), an uplift pressing strip (4), a T-shaped pedestal (5), an oblate small air bag (6), a small cover plate (7) and a hook-shaped tensioning strip (8). According to the thin steel sheet clamping and tensioning device and the method for clamping and tensioning the thin steel sheet, one air bag is adopted to clamp the thin steel sheet in place of an adjustable position handle; since the stress is uniform, the distortion of related parts is avoided, and local wrinkling deformation of the thin steel sheet is eliminated. The other air bag is used for tensioning the thin steel sheet in place of a cylinder, so that the bending deformation of the related parts is avoided, and the big-wave deformation of the thin steel sheet is eliminated. The problems of low efficiency and poor flatness of the thin steel sheet in the prior art that the thin steel sheet is required to be manually clamped by two persons are solved, the efficiency is increased, the benefit is increased, and the device and the method have broad market prospect.

Description

technical field [0001] A thin steel sheet clamping and tensioning device and a method for clamping and tensioning a thin steel sheet are particularly suitable for automatic clamping of thin steel sheets on high-precision laser processing equipment. Background technique [0002] In the process of high-precision laser processing, one type of workpiece is thin steel sheet. In order to ensure the processing quality, it is required that the position of the laser focus relative to the workpiece thin steel sheet does not change more than one-third of the thickness of the processed workpiece, that is, the thin steel sheet is required to be flat throughout the entire processing process, that is, clamping No deformation can occur during the cutting process, and no new deformation will be generated during the cutting process, and the thin steel sheet will not vibrate. [0003] In the past, the tensioning methods of thin steel sheets were mostly clamped by adjustable handles, and tensi...

AI Technical Summary

Problems solved by technology

When clamping the steel sheet, one person needs to hold the steel sheet, and the other person turns the adjustable handle to clamp it, which leads to low production efficiency

When the thin steel sheet is clamped and tensioned, local forces are applied, and the related parts will be deformed, resulting in serious unevenness of the thin steel sheet. Precision Machining Process Requirements
