Problems solved by technology
[0003] The present invention adopts a continuous trimming die for cutting the flash of forgings, changes the traditional design method that the edge of the trimming die is parallel to the flash of the forging, and designs the cutting edge of the trimming die as an inclined type, that is, the cutting edge and the flash of the forging are in the same shape. A certain angle solves the damage to the equipment caused by excessive trimming force and improves the technical problems such as the service life of the forging trimming die

Embodiment Construction
[0015] Such as Figure 1-9 As shown, the forging 1 moves downward after being stressed, and the flash 4 connected to the forging 1 first contacts with the edge 3 at the outermost high point of the trimming die 2, and the flash 4 of the forging 1 is cut off by shearing of the cutting edge 5 , as the forging 1 continues to move downward, the cutting edge at the inner low point of the trimming die 2 begins to contact the flash 4 until the lowest point 6 of the center line, and the cutting edge 5 of the trimming die 2 completely removes the flash 4 of the forging 1.
[0016] The selection of the angle of inclination of the trimming die edge and the flash of the forging of the present invention is determined by the following three aspects:
[0017] 1. The edge of the trimming die and the flash of the forging are at a certain angle to avoid direct contact between the forging and the die edge, effectively reduce the temperature of the die, and prevent the die edge from failing due to...

The invention relates to a trimming mold for continuously cutting a forged flash. The conventional design method that the cutting edge of the trimming mold is parallel to the flash of a forging piece is changed. The cutting edge of the trimming mold is designed as an inclined cutting edge, that is, the cutting edge and the flash of the forging piece form a certain angle. The trimming mold for continuously cutting the forged flash solves the technical problems that equipment is damaged by an overlarge trimming force and the service life of the forged trimming mold is prolonged and the like. The trimming mold for continuously cutting the forged flash comprises the cutting edge which is inclined, that is, the cutting edge and the flash of the forging piece form the certain angle, and the inclination direction is from the outer side of the cutting edge to the inner side of the cutting edge. The inclined angle is 3-5 degrees or 5-7 degrees. According to the trimming mold for continuously cutting the forged flash provided by the invention, the cutting edge of the forged trimming mold is designed in such a structure that the cutting edge and the flash of the forging piece form the certain angle so that the forging piece is basically not contacted with the cutting edge of the trimming mold when the forging piece is placed into an impression of the trimming mold, therefore, the trimming force is reduced while the contact time of the cutting edge and the forging piece is reduced, the temperature of the cutting edge is reduced, and the service life of the mold is remarkably improved.
Description
technical field [0001] The invention relates to a trimming die for continuously cutting off forging flash. Background technique [0002] The forging trimming die is one of the more expensive core dies on the forging production line. The trimming die works under high temperature and high pressure conditions. Usually, the cutting edge of the trimming die is designed to be parallel to the flash surface, and the contact time between the cutting edge and the forging is long, resulting in mold The temperature of the cutting edge is high, and the surface of the cutting edge and the parts near the surface layer are prone to failure, which directly leads to the failure and scrapping of the entire set of molds. For some larger forgings, the cross-sectional area of the flash is large, and the deformation resistance during edge trimming is large. Higher requirements. Contents of the invention [0003] The present invention adopts a continuous trimming die for cutting the flash of f...
