Abstract
The invention relates to a processing technology of an upper V-shaped anvil and a lower V-shaped anvil of an electro-hydraulic hammer, and belongs to the technical field of processing of the upper V-shaped anvils and the lower V-shaped anvils of the electro-hydraulic hammer. The processing technology comprises the following steps of (1) selecting blank materials, and placing the selected blank materials on a sawing machine to perform rough processing, wherein the opening angles of the upper V-shaped anvil and the lower V-shaped anvil are 105-115 degrees; (2) placing the rough processed blank materials into a heating furnace to perform first-time heating, and then performing first-time heat preservation; (3) performing second-time heating on the first-time heat preserved blank materials, performing second-time heat preservation, then placing the second-time heat preserved blank materials in fluid oil to perform quenching, and cooling the quenched blank materials to 400-500 DEG C; (4) performing third-time heating on the quenched blank materials, then performing third-time heat preservation, discharging the third-time heat preserved blank materials from the heating furnace and performing air cooling to 260-320 DEG C; and (5) performing fourth-time heating on the air cooled blank materials, performing fourth-time heat preservation, and then cooling the fourth-time heat preserved blank materials in the furnace to room temperature. The V-shaped anvil processed by the processing technology disclosed by the invention is free from transverse fracture, free from wear, and long in service life; products processed by the V-shaped anvils processed by the processing technology disclosed by the invention are good in quality.
Description
technical field [0001] The invention belongs to the technical field of processing an upper and lower V-shaped anvil of an electro-hydraulic hammer, and in particular relates to a processing technology for an upper and lower V-shaped anvil of an electro-hydraulic hammer. Background technique [0002] V-shaped anvil is one of the common free forging equipment tooling, which is usually used for drawing high alloy materials and mandrel drawing for long tube forgings. The V-shaped anvil is subjected to the thrust of the blank perpendicular to the surface of the V-shaped anvil, which has a component force in the horizontal direction, and the V-shaped anvil is prone to transverse fracture; the force of the V-shaped anvil is more complicated than that of ordinary flat anvils, and the V-shaped anvil is easy to wear , causing the scrapping of the V-shaped anvil; the quality of the products processed on the V-shaped anvil is poor. Contents of the invention [0003] The technical pro...
