Hydraulic hammer lower anvil structure

Abstract

The invention relates to a hydraulic hammer lower anvil structure which comprises an anvil body. Handling holes are formed in two sides of the anvil body respectively, the lower portion of the anvil body extends outwards to form a dovetail block, an external port and an internal port of the dovetail block are staggered, a distance alpha is formed between the external port and the internal port of the dovetail block, an included angle beta is formed between an inclined surface and a longitudinal vertical surface, and the external port is connected with the internal port to form the inclined surface. The hydraulic hammer lower anvil structure is simple in structure and convenient to manufacture, the external end face and the internal end face of the dovetail block are staggered, the included angle is formed between the inclined surface and the longitudinal vertical surface, so that parts of vibration and compression of a hydraulic hammer relative to a forging step in the forging process are eliminated, the service life of a lower anvil block is prolonged, cracking, abrasion and deviation are prevented, the problems of folding of shaft forgings in the forging process, unevenness of steps and the like are solved, and the working efficiency of forging equipment is improved. The forging quality of the forgings is greatly improved, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a hydraulic hammer lower anvil structure. Background technique [0002] At present, in the process of forging and forging, it is necessary to place the forging die under the forging equipment for forging processing. The 5-ton hydraulic hammer is generally forged through the lower anvil of the hydraulic hammer belt, and the object to be forged is placed on the base. The lower anvil of the hydraulic hammer reads the object for forging. Due to the large force, the lower anvil and the base will be worn, cracked and displaced, resulting in deformation and offset, which will affect the working efficiency of the forging equipment. The punched products are prone to folding, especially for shaft forgings, the shoulder steps are not smooth. Contents of the invention [0003] In view of the above-mentioned existing problems, the applicant has carried out research and improvement, and...
