Multi-pole electric spark marking head and production process thereof

Abstract

The invention discloses a multi-pole electric spark marking head and a production process thereof. The multi-pole electric spark marking head comprises a clamping device, an electrode assembly and anoperation frame, wherein one end of each locking screw makes contact with the electrode assembly; the electrode assembly comprises a transition plate, electrode heads, a matching seat and an edge seat; the electrode assembly can be freely assembled in an inner cavity of the clamping device; and the clamping device can be driven to move through the operation frame. When the whole device is used, firstly, the number of the electrode heads and the gap value between every two adjacent electrode heads are determined according to the actual marking requirement, then the selected electrode heads areassembled on the matching seat, and the mounting positions of the electrode heads can be selected in a personalized manner; then the matching seat and the edge seat are assembled on the transition plate, the position relation between the matching seat and the edge seat is adjusted according to the requirement, the locking screws at the two ends of the clamping device are screwed, and the electrodeheads reach the needed machining interval; and finally, the angle of the whole device is adjusted, the electrode heads are close to the surface of a workpiece to be machined, the whole device can beselected in a personalized manner, adaptability is good, and meanwhile assembling is simple.

Description

technical field [0001] The invention relates to the technical field of roll electric spark marking, in particular to a multi-pole electric spark marking head and a production process thereof. Background technique [0002] Steel rolling is an important field in steel production, and rolls are important tools for rolling steel plates (steel strips) or steel bars in steel plants, and are also one of the main consumable spare parts in rolling production. The working conditions of the roll are generally very harsh. It has to bear very complex alternating loads and impacts, as well as the working conditions of rapid cooling and rapid heating. In addition to requiring it to have sufficient strength and toughness, it is also required to have high wear resistance and thermal and impact resistance. Therefore, improving the hardness of the roll surface can reduce the amount of wear of the roll. Using roll surface repair and strengthening technology to improve the roll surface hardness...

Problems solved by technology

Among them, it is a feasible method to mark the surface of the roll by EDM. The existing EDM marking equipment often only has a single marking head, and the work efficiency is low. Therefore, an electric machine with multiple marking heads is needed. Spark marking equipment, at the same time, it needs to meet the ability to adapt the optional marking head, and at the same time, it needs to be easy to assemble and meet the actual production needs
