Die and die forging method for improving multi-directional die forging die life

Abstract

The invention discloses a mould and a die forging method thereof for prolonging the service life of a multidirectional die forged mould. The mould comprises an upper mould, a lower mould and a lateral male mould; the mould is characterized in that the lateral male mould comprises a small male mould which is located at the front end and a mould matrix which is located at the rear end; the front end of the small male mould is used for contacting a part and performing extrusion forming on the part to form a foot shape of the part; the rear end of the mould matrix is used for being fixed on a die holder or a piece of power equipment; and a contact place of the rear end of the small male mould and the front end of the mould matrix has a structure in a plane butting way or in the concave-convex coupling butting way which can prevent the small male mould from being rotated. The die forging method comprises the following steps that the mould is adopted; and during die forging, the small mould is changed to ensure the temperature of below 200 degrees centigrade. The mould and the die forging method have the advantages of capacities of prolonging the service life of the multidirectional die forged male mould and reducing wear of the mould, convenience in clamping, obviously improving the quality of the parts, greatly reducing production cost, greatly improving production efficiency, and realizing mass production of the parts by a multidirectional die forging process.

Description

technical field [0001] The invention relates to the field of multi-directional die forging dies in metal plastic forming, in particular to a die and a die forging method for improving the service life of the multi-directional die forging dies. Background technique [0002] Multi-directional die forging is a comprehensive process combining extrusion and forging, which uses a separable die to forge a forging with complex shape, no burrs, no die forging slope or small die forging slope under the action of one stroke of the press. Ordinary multi-directional forging dies generally include an upper die, a lower die and a lateral punch, and the three parts form a part cavity after the mold is closed. [0003] Since the forming of multi-directional die forging parts is carried out in a closed cavity with multiple parting surfaces, multi-directional die forging is a new die forging process with high product precision, high material utilization rate and high production efficiency.

Problems solved by technology

In this way, under the action of extrusion force, it is easy to wear or deform, forming large rounded corners and wrinkles, and the part flash is too large, forming wrinkles, and the quality is poor; the service life of the lateral punch is extremely low (generally dozens of pieces), High production cost, low efficiency, unable to form mass production capacity
