Special wire tightening device for linear cutting machine and linear cutting machine

Abstract

The invention provides a special wire tightening device for a linear cutting machine tool and the linear cutting machine tool. The special wire tightening device comprises a supporting base, a slide supporting base and a guide wheel, wherein the supporting base is fixedly arranged on a wire rack of the linear cutting machine tool; the slide supporting base is positioned below the supporting base, and can be assembled on the supporting base in a sliding mode vertically relative to the supporting base; and the guide wheel is assembled on the slide supporting base, and can move vertically along with the slide supporting base relative to the supporting base. According to the special wire tightening device, the supporting base on the special wire tightening device is improved, so that the special wire tightening device is better matched with a machine tool, and constant tension of a molybdenum wire cutting line is ensured; the quality and efficiency problems that when the linear cutting machine works, the surface of a part is rough, the cutting efficiency is low, the wire breaking cost is increased and the like due to molybdenum wire tension relaxation are solved; and the special wire tightening device is simple in structure and convenient to operate, and improves the cutting efficiency.

Description

technical field [0001] The invention relates to the technical field of an automatic wire tightening connection device for a wire cutting machine tool, in particular to a special wire tightening device for a wire cutting machine tool and a wire cutting machine tool including the same. Background technique [0002] Wire cutting machine tools are divided into fast wire cutting, medium wire cutting and slow wire cutting machine tools according to the wire walking method. Among them, the fast wire cutting machine tool is an original wire electric discharge processing mode in my country, which is widely used in our country. The fast wire cutting machine tool adopts the reciprocating cycle wire feeding method. The main advantages are high production efficiency and low processing cost, but there are also some The problem is that due to the fast wire feeding speed of the machine tool, problems such as loose electrode wire and broken wire are prone to occur, resulting in low precision ...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a special wire tightening device for wire cutting machine tools and a wire cutting machine tool, which solves the problem that the existing wire tightening device of the DK7763 wire cutting machine tool is a heavy hammer type, and the tension of the electrode wire is controlled by manually adding or subtracting gravity blocks. The weight-reducing block cannot realize the constant tension of the electrode wire, so it is prone to technical problems such as wire breakage and poor processing accuracy. At the same time, it also solves the problem that none of the spring-type wire tightening devices sold on the market can match the DK7763 wire cutting machine tool and cannot be installed on Technical Difficulties in DK7763 Wire Cutting Machine Tool
