One-way annular wire conveying system for electrolytic wire cutting

Abstract

The invention discloses a one-way annular wire conveying system for electrolytic wire cutting machining, and belongs to the field of electrochemical machining. The one-way annular wire conveying system comprises a driving wheel, an auxiliary wheel and a guide rail, wherein the driving wheel and the auxiliary wheel are matched with each other to drive annular wire to move; the guide rail is arranged on a supporting plate, a first sliding block is arranged on the guide rail, a fourth sliding block is arranged on one side of the first sliding block, and elastic materials are arranged between the first sliding block and the fourth sliding block; and the elastic materials are non-conductive and corrosion-resistant, a part of the annular wire penetrates through the elastic materials, and the elastic material can be extruded or loosened through the movement of the first sliding block so as to compress or loosen the annular wire. According to the one-way annular wire conveying system, a wire electrode is driven to one-way conveying wire through the driving wheel, the tension force of the annular wire is fed back to a computer in real time through a tensiometer, the operation of a tensioning shaft is controlled through the computer to achieve the change of the clamping degree of the elastic materials, and the effect of controlling the tension force of the annular wire in the machining area is achieved.

Description

technical field [0001] The invention relates to the field of electrochemical machining, in particular to a unidirectional circular wire feeding system for electrolytic wire cutting. Background technique [0002] Micro Electro Mechanical System (MEMS) is one of the most important scientific and technological advances in the 20th century, and it is also a hot spot of scientific research today. Micro-manufacturing technology is the foundation and core of micro-electro-mechanical systems. Electrolytic machining is removed in the form of ions, which has the advantages of no loss of tools, no influence of material hardness and cutting performance, and good surface quality. Compared with many other micro-machining The method has advantages in principle and is widely used in industries such as weapons, automobiles, molds, and medical equipment. [0003] Electrolytic wire cutting uses wire electrodes as tools, which is very suitable for the processing of high aspect ratio metal stru...

Problems solved by technology

After searching the current technology, it is found that the patent application No. 201010128961.2 proposes a circulating wire electrode system and processing method for electrolytic wire cutting. The circular wires are all in a tensioned state, and there is a large amount of deformation at the tensioning wheel, resulting in low durability of the circular wires, and metal wires with a diameter of not less than 100 μm are often used, and the service life is low
