Abstract

The invention provides a power transmission device for aluminum wire cut electrical discharge machining of an elastic center. The power transmission device comprises a main body assembly, a torque force adjusting assembly and a rotary power transmission assembly, and the main body assembly comprises the elastic center, a shell, a sliding chute and a sliding block; the torque force adjusting assembly is installed on the upper surface and the interior of the shell; and the rotary power transmission assembly comprises a first conductive rod, a pipe body, a first bearing, a first insulation pad, a conductive block, a second bearing, a second conductive rod and a second insulation pad. According to the power transmission device, during power transmission, through arrangement of the first conductive rod, the second conductive rod and the conductive block, after a power source is fed into the second conductive rod, electric power is transmitted to the first conductive rod through the conductive block, and finally transmitted to the elastic center; in the power transmission process, through arrangement of the first bearing and the second bearing, both the first conductive rod and the second conductive rod can be rotated; normal power transmission is not affected, the power transmission effect is guaranteed; and the aluminum wire cutting precision is improved.

Description

technical field

[0001] The invention relates to the technical field of aluminum material processing, in particular to an elastic tip power transmission device for wire electric discharge cutting of aluminum material. Background technique

[0002] Wire EDM belongs to the category of electrical processing. The instantaneous high temperature of EDM can melt, oxidize and corrode the local metal. When processing aluminum, wire EDM is often used to process it;

[0003] The elastic top is one of the commonly used front tops. There is a spring at the bottom of the top, so the top can expand and contract in the axial direction.

[0004] During aluminum processing, due to the abnormal discharge between the electrode wire and the conductive block, the elastic tip will inevitably rotate during the power transmission process. However, due to the limitation of its spring position, the elastic tip cannot rotate, which affects to a certain extent The effect of power transmission is impaire...
