Abstract

The utility model discloses a v-shaped anvil, and an included angle between two working surfaces of the v-shaped anvil is from 90 DEG to 100 DEG. The working surfaces are cylindrical surfaces, the top surfaces of the working surfaces are arced, the radius of the arc is from 800mm to 1500mm, the junctures of the top surfaces and upright surfaces are in an arced transition, and the radius of the arc is from 40mm to 200mm. The utility model has the advantages that the adopted technical scheme is the optimized design screened from a large number of simulation tests and is especially suitable for forging elements made of inductile materials; the rate of finished products is increased from the original rate as about 60% to 96% in forging tests of the elements made of semi-steel, stoma iron rolls, etc., so as to solve the cracking problems of fragile materials, meanwhile, to increase the drawing out efficiency and to completely meet the needs of mass production.

Description

A kind of " V " swage block

Affiliated technical field

The utility model relates to a kind of " V " swage block is the employed a kind of instrument of machine industry flat-die forging technical field.

Background technology

At present domestic at the forging half steel, and mostly adopt when making inductile material components such as mouthful iron roll common 600mm wide on, following " V " swage block, angle between two working face is 120 °, working face is the plane, because all to exist resistance of deformation usually bigger for this class material under forging temperature, plasticity is poor, problem such as easy to crack, and on employed, " V " is though swage block can help to avoid the weakness of this class material in forging processing aspect the compacting of heart portion down, but for this class material deficiency of aspect such as plasticity difference at high temperature, existing on, " V " swage block still is insurmountable down.And upper and lower " V " swage block self also exists the some shortcomings part, as forges the difference of being out of shape between asymmetric machined surface and the parts, and the component body internal strain is inhomogeneous or the like.Therefore, use the product that instrument processed of present this design quality problems such as transversal crack to occur through regular meeting, cause the Forging Technology yield rate to be had only about 60%, pulling efficient is also lower, is difficult to satisfy requirements of large-scale production.

Summary of the invention

Goal of the invention of the present utility model is at inductile material existing resistance of deformation under forging temperature bigger, plasticity is poor, weakness easy to crack, and the above-mentioned deficiency that in working face design, shows of existing upper and lower " V " swage block, a kind of forging processed finished products rate height is provided, can satisfies a kind of " V " swage block of producing needs in enormous quantities.

The utility model is by the following technical solutions: the angle between should two working faces of " V " swage block is 90---110 °, working face is a cylindroid, and its end face is circular arc, and arc radius is 880-1500mm, end face and vertical surface intersection are the circular arc transition, and arc radius is 40---200mm.

The beneficial effects of the utility model are that the technical scheme that is adopted is the optimal design that filters out in a large amount of simulated tests that new design is carried out, be particularly suitable for the forging of inductile material components, at half steel, make in the forging test of parts such as mouthful iron roll, yield rate rose to 96% by about 60% of the past, promptly solved the cracking problem of fragile material, simultaneously also improve pulling efficient, can satisfy requirements of large-scale production fully.
