Automatic wire tightening mechanism of wire cutting machine

Abstract

The invention discloses an automatic wire tightening mechanism of a wire cutting machine, and belongs to the field of machining. A supporting base is connected with a wire cutting machine body througha thread pair, the supporting base is connected with a sliding pole through the thread pair, an upper guide wheel is mounted on the supporting base through a bearing pedestal, the bearing pedestal isejected tightly through a set screw, a connecting piece is mounted on the lower portion of the sliding pole, the position of the connecting piece is adjusted through an adjusting nut, a sliding support is in sliding fit with the sliding pole, an upper spring is arranged on the upper end of the sliding support, a lower spring is arranged on the lower face of the sliding support, a lower guide wheel is mounted on the sliding support through the bearing pedestal, the lower guide wheel and the upper guide wheel are located on the same plane, and the supporting base and the sliding support are made of nylon materials. According to the automatic wire tightening mechanism of the wire cutting machine, a molybdenum wire cutting line constant tension device is added, the defect occurrence probability that due to loose molybdenum wire cutting line tension, during electric spark wire cutting, the machining surface is rough, the cutting efficiency is reduced, and the wire breaking cost is increased is reduced further, the structure is simple, the operation is convenient, time and labor are saved, and cutting efficiency is improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing and relates to an automatic wire tightening mechanism of a wire cutting machine. Background technique [0002] At present, there are many wire cutting machines used in the medical rehabilitation market. The tightness of the metal molybdenum wire of the traditional wire cutting machine is manually adjusted, and the strength of manual adjustment cannot be guaranteed for a long time. Accurate precision and surface roughness, and chip removal is not smooth, reducing cutting efficiency, and in severe cases, it is prone to broken wires. The existing wire tightening mechanisms on the market are generally relatively expensive, complicated in process, and low in stability. Based on this, the applicant optimizes the design on the basis of the traditional tightening mechanism to make the product. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the ...
