A method for forging with a 1800-ton diameter forging machine

Abstract

The invention relates to a forging method of a 1800-t radial forging machine. A round blank forging method includes the steps of first-time forging to Nth-time forging; when the Nth-time forging is carried out, a round blank obtained through the N-1th-time forging is still clamped on an M1 operating machine, automatic forging is switched into manual control, the round blank obtained through the N-1th-time forging is fed in the direction of an M2 operating machine in an air mode, different-side clamping is manually started, the size of a forging hammer and the specification of a finished product are manually input, manual control is carried out, the M1 operating machine moves backwards, the round blank is pushed by the M1 operating machine in the direction of the M2 operating machine to the clamping position of the M2 operating position, then automatic forging is selected, the round blank is clamped by the M2 operating machine for secondary drawing, and the next-time forging is implemented. The difference between a square blank forging method and the round blank forging method is that when the N-1th-time forging and the Nth-time forging are carried out, one-time drawing is carried out through manual control. Forged-head bending at the two ends of the forged blank forged with the forging method is avoided.

Description

technical field

[0001] The invention relates to a forging method of a 1800-ton diameter forging machine, specifically a method for forging a round billet and a forging square billet of a GFM 1800-ton diameter forging machine. Background technique

[0002] The applicant's GFM 1800t radial forging machine is currently the largest radial forging machine in the world, with an annual production capacity of 100,000 tons of forging materials, including: square steel, flat steel, round steel, stepped shafts, and forged pipes. The product variety involves carbon steel, bonded steel, die steel, CrNi stainless steel, petroleum steel and other varieties. The product specification is ∮560~∮80, the raw material weight is 10 tons, and the longest forging material can be produced with a length of 22 meters. . With the marketing model, the change from a seller's market to a buyer's market. Users have higher and higher requirements for products in terms of cost of use. Not only the interna...
