A unidirectional circular wire feeding system for electrolytic wire cutting

Abstract

The invention discloses a unidirectional circular wire feeding system for electrolytic wire cutting, which belongs to the field of electrochemical processing and includes a driving wheel, an auxiliary wheel and a guide rail; the driving wheel and the auxiliary wheel cooperate with each other to drive the circular wire to move , the guide rail is set on the support plate, the first slider is installed on the guide rail, the fourth slider is arranged on one side of the first slider, and an elastic material is arranged between the first slider and the fourth slider, the The elastic material is non-conductive and corrosion-resistant, a part of the annular wire passes through the elastic material, and the elastic material can be squeezed or loosened by the movement of the first slider so as to compress or loosen the annular wire. The device drives the wire electrode to move the wire in one direction through the driving wheel, and feeds back the tension force of the ring wire to the computer in real time through the tensiometer. Effect of tension in the machining area.

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
