Abstract
The invention discloses an integral head cover heading die, which comprises a heading upper die and a heading lower die. By taking the using direction as a reference, the heading lower die is a drum-shaped cylinder with an upper opening; the upper end face of the side wall of the drum-shaped cylinder and the inner side wall of the drum-shaped cylinder are in arc transition connection; the lower end of the heading upper die is longitudinally provided with a circle of longitudinal annular opening; the side wall of the lower end of the longitudinal annular opening and the end face of the lower end of the heading upper die in arc transition connection; and the centers of the heading upper die and the heading lower die are collinear. A high-temperature heated steel ingot is made into a drum-shaped blank by a distributive extrusion process, and the side wall of the drum-shaped blank is extruded into a flange extending outwards radially, so that the flange of the integral head cover and the head cover drum are integrated into a whole without welding line; and because the interior of a forge piece is always kept in a three dimensional stress state in the heading and extruding process of the flange, the interior has no tensile stress and defects such as cracks cannot occur; and the integral head cover heading die has the advantages of compact structure, high strength, and reliable and safe use.
Description
Technical field
The present invention relates to a kind of metal processing mold, particularly a kind of integral head cover heading die.
Background technology
Huge for the large-scale integral top cover owing to its volume and weight, present free forging process is difficult to reach one-shot forming, present integral head cover is first moulding one hollow annular shape cylinder, and then the barrel of a upper end open lower end closed identical of moulding with hollow annular cylinder internal diameter, the barrel external diameter is less than hollow annular shape cylinder external diameter, barrel upper end with hollow annular cylinder lower end and upper end open lower end closed welds together then, integral head cover that has flange of final formation, weld seam just is easy to cracking like this, uses dangerous, unstable.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of integral head cover heading die, the flange that uses the integral head cover that this integral head cover heading die forms and the top cover staving no weld seam that is structure as a whole uses reliably, safety.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of integral head cover heading die, comprise jumping-up patrix and jumping-up counterdie, to use direction to be benchmark, the jumping-up counterdie is the tubbiness cylinder of a upper end open, adopt arc transition to be connected between this tubbiness column side wall upper surface and its madial wall, jumping-up patrix lower end vertically is provided with the vertical circular opening of a circle, this vertical circular opening and the staving blank upper end sidewall coupling that needs jumping-up, this vertical circular opening lower end sidewall is connected with jumping-up patrix lower end surface arc transition, jumping-up patrix and jumping-up counterdie center conllinear.
Useful technique effect of the present invention is: after the steel ingot that the present invention heats high temperature adopts the distribution extrusion process to manufacture the staving blank of upper end open lower end closed, by the present invention the sidewall of staving blank is squeezed into the flange that extends radially outwardly, the flange of this integral head cover and the top cover staving no weld seam that is structure as a whole like this, and because flange forging inside in the upsetting squeeze process remains at the three-dimensional compressive stress state, its inner no tension, defective such as can not crack, its compact structure, intensity is big, uses reliable, safety.

The specific embodiment
Embodiment: a kind of integral head cover heading die, comprise jumping-up patrix 3 and jumping-up counterdie 2, to use direction to be benchmark, jumping-up counterdie 2 is the tubbiness cylinder of a upper end open, adopt arc transition to be connected between this tubbiness column side wall upper surface and its madial wall, jumping-up patrix 3 lower ends vertically are provided with the vertical circular opening 31 of a circle, this vertical circular opening 31 and the staving blank upper end sidewall coupling that needs jumping-up, these vertical circular opening 31 lower end sidewalls are connected with jumping-up patrix 3 lower end surface arc transition, jumping-up patrix 3 and jumping-up counterdie 2 center conllinear.
