Abstract

The invention relates to a novel ultrahigh taper ring rolling method. According to the method, a ring with internal and external straight walls is directly obtained after cogging, the aluminum alloy blank is changed to be in the shape with the exterior being taper and an inner hole being a straight round hole through drawing of a mandrel, and accordingly the height of the blank can be increased to the preset dimension. By means of the method, the material utilization rate can be increased, the production cost is reduced, the mechanical property of materials can be significantly improved, and the corrosion resistance of aluminum alloy is greatly improved.

Description

A kind of novel super-high Conical ring rolls ring method

Technical field

The present invention relates to forging technology field, more particularly, to a kind of novel super-high Conical ring rolls ring method.

Background technology

With developing rapidly of China's aerospace industry, modern national defense industry and transportation, important stressed member and knot The lightweight of component, promotes the cry more and more higher for steel with aluminum, the usage amount of aluminum alloy forge piece and demand just to incrementally increase. When domestic at present each factory produces superelevation special-shaped forge parts, after all adopting production straight wall superelevation cylindrical member, by way of Vehicle Processing, plus Work becomes special-shaped ring, so on the one hand reduces stock utilization, improves production cost;On the other hand also result in forging stream Line is destroyed in follow-up machining process, reduces the mechanical property of material, also reduces the resistance to corrosion of aluminium alloy.

Currently available technology carries out changing forging punching for after ingot casting heating a period of time, after punching terminates, is air cooled to room temperature, After machining hinders endoporus clearly, reheat and carry out saddle support reaming, after melting down insulation a period of time, then carry out fullering with the core bar, again After melting down insulation a period of time, then carry out saddle support reaming, rolling ring to predetermined straight wall size, after being air cooled to room temperature, by forging from straight Wall cylindrical member is machined to taper cylindrical member.But prior art one side reduces stock utilization, improves production cost; On the other hand also result in forging flow lines to be destroyed in follow-up machining process, reduce the mechanical property of material, also drop The low resistance to corrosion of aluminium alloy.

Content of the invention

The applicant is directed to above-mentioned existing issue, has carried out Improvement, provides a kind of novel super-high Conical ring to roll ring Method, it not only increases stock utilization, also a saving production cost.

The technical solution adopted in the present invention is as follows:

A kind of novel super-high Conical ring rolls ring method, comprises the following steps:

The first step: blanking: one section of cutting is as aluminum alloy blank on aluminium alloy cast ingot;

Second step: heat for the first time: described aluminum alloy blank is put and is heated to 460 DEG C~500 DEG C to heating furnace, Ran Houbao Take out from heating furnace after warm 20~30h;

3rd step: change forging: aluminum alloy blank is carried out changing with forging, then by described aluminum alloy blank punching, be cooled to room temperature Afterwards endoporus is hindered clearly;

4th step: heat for second: described aluminum alloy blank is placed again in heating furnace being heated to 460~480 DEG C, so Take out from heating furnace after insulation 10~15h afterwards;

5th step: fullering with the core bar: pulled out described aluminum alloy blank to more than 1200mm using mandrel, make described aluminium alloy The outside of blank forms taper, and the endoporus of described aluminum alloy blank is straight section circular hole;

6th step: melt down for the first time: the 5th step gained aluminum alloy blank is placed again into after insulation 8~12h in heating furnace Take out from heating furnace, the temperature of this heating furnace is 440~460 DEG C;

7th step: saddle support reaming: saddle support reaming is carried out to described aluminum alloy blank by straight plug and upper flat anvil, makes described The endoporus of aluminum alloy blank forms the outside identical pyramidal structure with aluminum alloy blank.

8th step: melt down for the second time: the inside and outside aluminum alloy blank being taper is put into after insulation 5~8h in heating furnace Take out from heating furnace;

9th step: roll over ring: aluminum alloy blank is carried out roll over ring using core roller and home roll, make described aluminum alloy blank roll over ring extremely Preliminary dimension.

Its further technical scheme is::

Described mandrel roller one end diameter is less than other end diameter, the stage casing of described core roller along described core roller periphery to extension Stretch formation tapered flanges;Also form tapering in one end of described home roll.

Beneficial effects of the present invention are as follows:

The inventive method is directly inside and outside straight wall ring after cogging, blank enabled aluminum alloy to by fullering with the core bar be changed into outside be Taper, endoporus are straight circular hole, so that the height of blank can pull out to preliminary dimension, the inventive method can not only improve material Utilization rate, save production cost, the mechanical property of material can also be increased substantially simultaneously, substantially increase the anti-corruption of aluminium alloy Erosion ability.
