Wire cutting machine

Abstract

The invention discloses a wire cutting machine which comprises a nut and a lead screw. The nut comprises an outer nut body and an inner nut body. The outer nut body is arranged on the inner nut body in a sleeving manner. The inner nut body is arranged on the outer portion of the lead screw in a sleeving manner and can move on the lead screw. A spiral groove is formed in the inner nut body. An inclined cutting portion is arranged at the end of one side of the lead screw. An elastic locating part embedded in the cutting portion is arranged on the cutting portion. An arc groove carrying out pathguiding on the elastic locating part is formed in the outer nut body. A locating groove with the depth larger than that of the arc groove is formed in one end of the arc groove. A locating bearing isarranged on the contact face of the inner nut body and the outer nut body. The wire cutting machine is simple in structure, convenient to operate, low in price, reliable in performance and capable ofachieving the function of automatic limiting protection.

Description

technical field [0001] The invention relates to the technical field of wire cutting, in particular to a wire cutting machine. Background technique [0002] At present, the wire cutting technology and wire cutting machines on the market are widely used in all walks of life, but its cutting accuracy and cutting efficiency are difficult to be improved by a large length, which will always be limited due to various reasons, mainly as follows Question: 1) There are two types of wire-feeding mechanisms at present, one is step-driven fast wire-feeding, and the other is slow-feeding wire-feeding, but the stepping-driven fast wire-feeding machine tool equipment in these two methods is low in price and low in operating costs , but the processing is unstable and the accuracy of the processing size is poor. Although the slow-moving wire cutting machine is expensive, the processing is stable, and the dimensional accuracy is high, but the operating cost is high; 2) The chip removal effect ...

[0002] At present, the wire cutting technology and wire cutting machines on the market are widely used in all walks of life, but its cutting accuracy and cutting efficiency are difficult to be improved by a large length, which will always be limited due to various reasons, mainly as follows Question: 1) There are two types of wire-feeding mechanisms at present, one is step-driven fast wire-feeding, and the other is slow-feeding wire-feeding, but the stepping-driven fast wire-feeding machine tool equipment in these two methods is low in price and low in operating costs , but the processing is unstable and the accuracy of the processing size is poor. Although the slow-moving wire cutting machine is expensive, the processing is stable, and the dimensional accuracy is high, but the operating cost is high; 2) The chip removal effect of the conventional wire cutting machine is poor, resulting in easy Short circuits and frequent wire breakages occur, which eventually lead to low cutting efficiency; 3) The wire storage drum of the current cutting machine will be affected by the bed during the reversing process and cause vibration, and wire vibration will occur during cutting, which will affect the cutting accuracy; 4) In addition, some silk threads are easy to wear after long-term use, and manual inspection is required, but the naked eye inspection is judged by the operator's experience, which leads to errors and affects the final cutting effect, so it needs to be improved
