An anti-deviation device for wire cutting wire feeding mechanism

Abstract

The invention belongs to the field of wire cutting, in particular to an anti-deviation device for a wire-cutting wire feeding mechanism. In the existing wire-cutting wire feeding mechanism, the distance between the transmission wheels is usually constant, which means that the wire electrode The tension is constant. If the position of the electrode wire is shifted, it is often difficult to adjust the problem. The following scheme is proposed, which includes a chassis, and four support rods are symmetrically slidingly connected in the case, and the support rods are rotated. The transmission wheel is sleeved, and the same electrode wire is connected to the transmission on the four transmission wheels. A rotating shaft is connected to the inner wall of one side of the cabinet. The invention can release the limit on the rotating shaft by starting the double-axis motor and can drive the rotating shaft at the same time. The rotation can drive the four transmission wheels away from each other two by two to realize the tight support and limit of the electrode wire, which can effectively prevent the electrode wire from shifting during work, so it has good practicability.

Description

technical field [0001] The invention relates to the technical field of wire cutting, in particular to an anti-deviation device for a wire feeding mechanism of wire cutting. Background technique [0002] Wire cutting is a processing technology that uses a moving wire electrode to cut a workpiece. When cutting, it is necessary to use the wire cutting wire feeding mechanism to transport the electrode wire. In the wire-cutting wire feeding mechanism, a plurality of transmission wheels are usually arranged, and at least two transmission wheels are arranged opposite to each other, so that the electrode wire passes between the two opposite transmission wheels, and the two transmission wheels are used to compress the electrode wire and The electrode wire is conveyed. [0003] However, in the existing wire cutting wire feeding mechanism, the distance between the transmission wheels is usually constant, that is, the tension of the electrode wire is constant. If the position of the e...

Problems solved by technology

[0003] However, in the existing wire cutting wire feeding mechanism, the distance between the transmission wheels is usually constant, that is, the tension of the electrode wire is constant. If the position of the electrode wire deviates, it is often difficult to adjust. Therefore, we propose an anti-deviation device for wire cutting wire feeding mechanism to solve the above-mentioned problems
