Clamp device for metal plate cutting

Abstract

The invention discloses a clamp device for metal plate cutting. The clamp device comprises a tool table, clamp tables are arranged on the tool table, electromagnetic coils, right-angle clamps and clamp seats are arranged in the clamp tables, the clamp seats are slidably arranged in the clamp tables, the right-angle clamps are movably arranged at the bottoms of the clamp seats, and the right-angle clamps each are composed of a plurality of thin metal sheets which are attached to one another. According to the clamp device, the electromagnetic coils are electrified to generate a strong magnetic field to enable the clamp seats to move downwards, the clamp seats moving downwards drive the right-angle clamps to move downwards at the same time, the right-angle clamps are contracted into the clamp seats after making contact with a metal plate to be machined, the right-angle clamps not making contact with the surface of the metal plate to be machined are distributed on one side of the right-angle side of the metal plate, the two right-angle clamps are attached to the right-angle sides of the plate respectively to form wrap angles matched with the vertexes of the plate, the vertexes of the plate are surrounded in the wrap angles, it can be guaranteed that the position of the plate is stable when the plate is transversely cut, thus, tools such as a vice do not need to be operated, power-on starting clamping is efficient and rapid, and the clamping efficiency is greatly improved.

Description

technical field [0001] The invention relates to the related technical field of plate processing, in particular to a clamp device for cutting metal plates. Background technique [0002] Iron and steel plants have high requirements on the dimensional accuracy and profile of thin steel plates. After the thin steel plates are cut by a cross-cutting machine, the adjacent sides are usually not completely vertical, or the width of the steel plates will deviate after cutting. The deviations specified in the steel industry are usually plate length deviations and diagonal deviations, which are essentially requirements for the machining accuracy of cross-cutting machines. [0003] The cutting accuracy control of thin steel plate is mostly controlled by the cutting machine's own accuracy. The cutting machine mainly uses clamps for clamping and fixing. The existing plate cutting fixtures mainly include vise, bolt fastening and other forms. The above-mentioned fixtures all have the prob...

AI Technical Summary

Problems solved by technology

The existing plate cutting fixtures mainly include vise, bolt fastening and other forms. The above-mentioned fixtures all have the problem of inconvenient manual operation, and because the processing such as cross-cutting needs to be transposed multiple times according to the size of the plate body and processing deviation, it is necessary to Multiple loading and unloading of fixtures requires multiple long-term shutdowns of cutting equipment, which affects processing efficiency
