Description
Technical Field
The invention relates to small hole machining, in particular to the technical field of wire feeding guide hole machining of wire rod machining equipment, and particularly relates to a small hole strengthening device and a wire feeding guide hole machining method using the small hole strengthening device.
Background
Pinholes are a very common and important feature in industrial production facilities, and their performance often has a significant impact on the production process and product quality. For example, for wire processing equipment such as wire bending, wire guiding parts are often arranged on a wire feeding device on the wire processing equipment, wire feeding guiding holes for wires to pass through are usually arranged on the wire guiding parts, and in the use process, the wire feeding guiding holes continuously rub with the wires, so that abrasion is easily generated, and finally, the guiding error is overlarge.
The key to improve the problems is to strengthen the hole wall by a certain strengthening technical means so as to improve the wear resistance and fatigue resistance of the small hole. Shot peening, ultrasonic impact peening and other techniques are relatively common effective means of strengthening critical surfaces by mechanical strain. The basic principle is that the surface layer of the part is cold-worked and hardened by cold extrusion, and residual compressive stress is generated. The cold work hardening causes the metal material lattice to distort, the strength is improved, the residual compressive stress with high amplitude is formed, the tensile stress of the workpiece formed by mechanical processing, heat treatment, welding, laser cutting, electroplating or hardening coating is counteracted, the crack initiation is effectively restrained, the surface hardness of the part and the wear resistance and fatigue resistance are improved to a certain extent, and the service life of the part is prolonged.
However, the existing mainstream mechanical strain strengthening technology can only strengthen the outer surface or the large-size inner surface of the part in most cases. The difficulty in strengthening the walls of small holes is that the strengthening tool is generally difficult to extend into the holes because of the small diameter of the small holes, so that radial impact strengthening is performed on the walls of the holes, a certain inclination angle is required to be maintained for strengthening, and the larger the depth-to-diameter ratio is, the larger the inclination angle is, the poorer the strengthening effect and the controllability are. In view of the above, there are no devices and methods available in the market that can effectively strengthen the walls of small holes.
