Problems solved by technology

However, the threaded steel roll has transverse ribs on the entire circumference, and the existing electric discharge machining equipment can only realize the horizontal X-axis, longitudinal Y-axis and vertical Z-axis movements in the plane, which is very important for the processing of rolled rebar. The roll has transverse ribs on its circumference, and it is difficult to process workpieces that require the workpiece to rotate

Description

technical field [0001] The present invention relates to the technical field of equipment for processing the upper transverse ribs of threaded steel rolls, and more specifically, relates to a device for machining the transverse ribs of threaded steel rolls, and an electrical discharge machining method for the transverse ribs of threaded steel rolls. Background technique [0002] The roll is an important equipment for steel rolling, which can make the steel deform plastically between the rotating rolls by rolling pressure, and obtain the desired shape and size. At the same time, the roll is also an industrial material that is easy to wear and tear. Rebar refers to ribbed steel bar, which has many uniformly distributed transverse ribs on its surface. According to the national standard, the helix angle between the transverse rib groove (crescent) of rebar and the longitudinal axis of rebar is between 45° and 75°. The rebar roll refers to the roll used for rolling rebar. When rol...
