Abstract

The invention discloses it is a kind of using open die forging equipment production alloy special-shaped titanium forging method, including charged material weight calculatings, Fixture Design, blank preparation, it is preforming, form and etc..The present invention produces special-shaped forge parts using existing open die forging equipment, easy forging mold and demoulding equipment need to only be made, therefore development cost is low, period is short, disposable less investment, technical requirements are not high, and technical requirements are not high, suitable for the production of development stage forging part and the production of small lot forging part.

Description

A method of alloy special-shaped titanium forging is produced using open die forging equipment
Technical field
The present invention relates to a kind of methods using open die forging equipment production alloy special-shaped titanium forging, belong to titanium alloy forging skill Art field.
Background technique
Titanium alloy is widely used in space flight, aviation and ship etc. because having many advantages, such as intensity height, high temperature resistant, corrosion-resistant Field.For common alloy of titanium forging, production technology is more mature, and the requirement of space flight special-shaped forge parts (such as wheel hub) performance indicator Strictly, forging technology is more complicated, and usually need to be using large-scale forging equipment through die-forging forming, however die forging tooling expense is thrown Enter it is larger, about ten it is tens of thousands of arrive hundreds of thousands, technical requirements are high, are unfavorable for the development work of early period.Although for relatively simple different Shape Forging can also use the direct machine add-on type of mach mode, but because of processing be special-shaped forge parts, in machine plus material in the process Material loss is big, at high cost.
Therefore be badly in need of finding a kind of method at low cost, material loss is small, technical requirements are not high, it is closed to forge qualified titanium Golden special-shaped forge parts.
Summary of the invention
In view of the deficiency of the prior art, existing open die forging equipment is utilized the object of the present invention is to provide a kind of The method for producing alloy special-shaped titanium forging, to reduce cost.
To achieve the above object, the technical solution adopted by the present invention is that: it is a kind of using open die forging equipment production titanium alloy it is different The method of shape Forging, includes the following steps:
(1) charged material weight calculates: according to the volume of machine plus preceding forging stock, computer adds preceding forging, the i.e. weight of blank, that is, feed intake weight Amount;
(2) Fixture Design: according to the size of forging stock, designing forging mold, and the forging mold includes upper mold and lower die, on Mould is punch-pin, and the type chamber of lower die is that the rotary table of two diameters of different sizes is formed by stacking up and down, wherein lower die cavity bottom diameter Consistent with the bottom outer diameter of machine plus preceding forging, for the convenience of demoulding, the draft angle of upper mold and lower die design is 7 degree or so;
(3) prepared by blank: according to charged material weight, calculating blank height, obtains blank specification, then passes through open die forging equipment system The blank of standby qualification out;
(4) preforming: lower die is placed on the lower anvil of open die forging equipment, the operation machine clamping of upper mold open die forging equipment is standby With;Then the blank heated is put into lower die;Upper mold is placed on blank again, pays attention to centering;Then upper mold is depressed 1/5 Then ~ 1/4 stroke utilizes the promotion of operation machine, directly takes out upper mold, overturn 180 degree, base using operation machine clamping lower die Material directly falls off from lower die, obtains preforming blank;
(5) it forms: lower die being placed on the lower anvil of open die forging equipment again, the operation machine of upper mold open die forging equipment is pressed from both sides It holds spare, preforming blank is put into lower die, then upper mold is placed on blank, pays attention to centering, be then pressed down to upper mold Position, obtains forging after molding, is then promoted using operation machine clamping upper mold, forging is separated with lower die, then utilizes Simple demoulding Tooling realizes that forging is separated with upper mold.
Compared with prior art, the beneficial effect that the present invention has is: producing abnormity using existing open die forging equipment Forging only need to make easy forging mold and demoulding equipment, therefore development cost is low, and the period is short, disposable less investment, skill Art is of less demanding, and technical requirements are not high, suitable for the production of development stage forging part and the production of small lot forging part.
Detailed description of the invention
Fig. 1 be the present invention relates to forging schematic diagram, wherein solid line surround part be machine add after forging, dotted line packet The part enclosed is the forging stock before machine adds;
Fig. 2 be the present invention relates to upper mold schematic diagram;
Fig. 3 be the present invention relates to lower die schematic diagram.
Specific embodiment
Now in conjunction with attached drawing, the invention will be further elaborated.
Embodiment one
As shown in Figure 1-3, the method using open die forging equipment production alloy special-shaped titanium forging of the present embodiment, including walk as follows It is rapid:
(1) charged material weight calculates: according to the volume of machine plus preceding forging stock, i.e. the volume that red dotted line includes in Fig. 1, before computer adds Forging, i.e. the weight M of blank, i.e. charged material weight M;
(2) Fixture Design: according to machine plus preceding forging, the i.e. size of blank, forging mold is designed, forging mold includes upper mold And lower die, upper mold are punch-pin, the type chamber of lower die is that the rotary table of two diameters of different sizes is formed by stacking up and down, wherein drag chamber The bottom outer diameter φ D of forging is consistent before base diameter φ D adds with machine, for the convenience of demoulding, the draft angle of upper mold and lower die design It is 7 degree or so;
(3) prepared by blank: according to charged material weight M, calculating blank height H, obtains blank specification φ D × H, then pass through freedom Forging equipment prepares qualified blank;
(4) preforming: lower die is placed on the lower anvil of open die forging equipment, the operation machine clamping of upper mold open die forging equipment is standby With;Then the blank heated is put into lower die;Upper mold is placed on blank again, pays attention to centering;Then about by upper mold pressure 1/5 ~ 1/4 stroke (preforming blank bore depth only has the 1/5 ~ 1/4 of actual depth) then being mentioned using operation machine It rises, directly takes out upper mold, overturn 180 ° using operation machine clamping lower die, blank directly falls off from lower die, obtains preforming Blank;
(5) it forms: lower die being placed on the lower anvil of open die forging equipment again, the operation machine of upper mold open die forging equipment is pressed from both sides It holds spare, preforming and after reheating blank is put into lower die, then upper mold is placed on blank, pays attention to centering, so Afterwards in place by upper mold pressure, i.e., the plane B of the plane A of upper mold and lower die are essentially coincided, obtains forging after molding;
(6) it demoulds: due to the design of draft angle, preforming process, and using suitable lubricant when molding, pass through freedom Forge the clamping of two operation machines of equipment, it is easy to open forging and mold separation.
