Abstract

The invention provides a die for forging a spherical / ellipsoidal head. The die comprises a lower die body, a plug, a spacing ring, a guide pressing plate and a plunger chip. The inner wall of the lower die body of the die is conically wavy, the plug is arranged at the lower end of the inner wall of the lower die body, the upper end of the outer wall of the lower die body is connected with the lower end of the inner wall of the spacing ring, a round hole in the upper end of the inner wall of the spacing ring is connected with the lower end of the guide pressing plate, and an inner hole in the guide pressing plate is provided with the plunger chip which is a cylindrical cone. According to the die for forging the spherical / ellipsoidal head, use of steel ingot materials and the chipping allowance for follow-up machining are reduced in forging, the production cycle is shortened and economic efficiency is improve; meanwhile, fiber textures of forge piece materials can be distributed according to shapes, the mechanical property is reliable, the service life is long and the security coefficient is high.

Description

Forging is spherical/mould of ellipsoidal head
Technical field
The invention belongs to forging and stamping manufacturing technology field, particularly a kind of forging spherical/mould of ellipsoidal head.
Background technology
Spherical/ellipsoidal head, be normally forged into cylindrical or be forged into after a counterbore cylindrical again the method by machining obtain spherical/ellipsoidal head.This forging method waste steel ingot material, in follow-up machining, its chipping allowance is large simultaneously, and the production cycle is long, and business efficiency is low.By machining spherical/ellipsoidal head, the fibr tissue of its material not conformal distribute, service life is short, safety coefficient is low.
Summary of the invention
Object of the present invention, be for forging in sum spherical/problems that ellipsoidal head exists, provide a kind of forging spherical/mould of ellipsoidal head.By this mould forging spherical/ellipsoidal head, reduce use to steel ingot material and the chipping allowance of follow-up machining while forging, shorten the production cycle, make the fibr tissue conformal of forging material distribute simultaneously, reliable in mechanical performance, safety coefficient is high.
Forging of the present invention is spherical/mould of ellipsoidal head, include counterdie, plug, spacing ring, guiding pressing plate, drift.The inwall of counterdie is tapered wavy, and the inwall lower end of counterdie is provided with plug, is disposed with lifting eye, counterdie holding tank on the outer wall of counterdie.The outer wall upper end of counterdie is connected with the inwall lower end of spacing ring, on the outer wall of spacing ring, is provided with hoisting ring.The inwall upper end circular hole of spacing ring is connected with the lower end of guiding pressing plate, on the endoporus of guiding pressing plate, is provided with drift, and drift is cylinder bullet, and its upper end is provided with drift holding tank.
Forging of the present invention is spherical/mould of ellipsoidal head, reduce the use to steel ingot material and the chipping allowance of follow-up machining while forging, and shorten the production cycle, improve through efficiency, make the fibr tissue conformal of forging material distribute, reliable in mechanical performance simultaneously, long service life, safety coefficient is high.
Accompanying drawing explanation
Fig. 1, be forging of the present invention spherical/schematic diagram of the mould structure of ellipsoidal head;
Fig. 2, be forging of the present invention spherical/mould of ellipsoidal head uses the structural representation of state;
Fig. 3, be forging of the present invention spherical/mould of ellipsoidal head use after forging moulding spherical/schematic diagram of ellipsoidal head structure.
The specific embodiment
Below in conjunction with above-mentioned accompanying drawing example, to forging of the present invention spherical/mould of ellipsoidal head is further described.
Forging of the present invention is spherical/mould of ellipsoidal head, include counterdie 1, plug 2, spacing ring 3, guiding pressing plate 4, drift 5.The inwall of counterdie 1 is tapered wavy, and the inwall lower end of counterdie 1 is provided with plug 2, and it can stop metal flow.On the outer wall of counterdie 1, be disposed with lifting eye 7, counterdie holding tank 6.The outer wall upper end of counterdie 1 is connected with the inwall lower end of spacing ring 3, is provided with hoisting ring 8 on the outer wall of spacing ring 3.The inwall upper end circular hole of spacing ring 3 is connected with the lower end of guiding pressing plate 4, on the endoporus of guiding pressing plate 4, is provided with drift 5, and endoporus plays a part guiding.Drift 5 is cylinder bullet, and its upper end is provided with drift holding tank 9.
Forging of the present invention is spherical/and the mould of ellipsoidal head is while using, drift 5 is swept away by the endoporus arranging on guiding pressing plate 4, make spherical/ellipsoidal head blank 10 moulding, then by moulding spherical/ellipsoidal head blank 10, process and make spherical/ellipsoidal head 11 by machine cut.
