Abstract

An aluminum alloy lubrication process comprises the following steps that (1) before the beginning of ring rolling, an oily nanometer lubricating agent is evenly sprayed onto a conical roller, a core roller, a clasping roller and a workbench by the thickness of 2mm; (2) after the beginning of ring rolling, a water-based lubricating agent is used for conducting lubrication; (3) during the initial stage of ring rolling, the spray flow of the water-based lubricating agent is controlled to be 5ml/s, and sprayed parts include the conical roller and the upper end face, the lower end face and the outer circle of a workpiece; (4) during the middle stage of ring rolling, the workpiece is expanded radially, the spray flow of the water-based lubricating agent is controlled to be 30ml/s, and sprayed parts include the clasping roller and the outer circle and corner angles of the upper and lower end faces of the workpiece; (5) during the terminal stage of ring rolling, the spray flow of the water-based lubricating agent is 10ml/s, and a sprayed part is the outer circle of the workpiece; and (6) in the whole ring rolling process, if a white and bright area exists on the surface of the workpiece, the water-based lubricating agent is sprayed onto the area in a centralized mode. Operation is convenient.

Description

Lubrication for aluminum alloy technique

Technical field

The present invention relates to forging and forming technology technical field, especially a kind of lubrication for aluminum alloy technique.

Background technology

With developing rapidly for China's aeronautical and space technology, spacecraft lightweight aerospace field effect increasingly It is important, aluminium alloy as a kind of intensity it is high, density is little, high comprehensive performance alloy, application is more and more extensive.Due to aluminium alloy A series of features such as coefficient of friction is big, poor fluidity, adhesiveness are big, during forging rolling ring, on the one hand because larger rubs Wipe, surface temperature can be made to increase serious, affect the final microstructure and mechanical property of product;On the other hand, big adhesiveness can be led Cause during rolling ring, it is easy to stick to the surface of equipment, cause product surface quality poor, when serious, can be by the folder on surface Skin is ground in body, causes finally to detect a flaw unqualified and scrap.During rolling ring, increase lubrication technology, can both reduce work Friction between part and equipment, can prevent the generation of bark pocket again, it is ensured that the stable and final products of product rolling ring process Quality.

In prior art, aluminum alloy forged rolling ring seldom has lubrication, or lubricates not in place, causes product surface quality very Difference, and deformation not enough uniformly causes final performance discrete larger.

The content of the invention

The applicant is for the shortcoming in above-mentioned existing production technology, there is provided lubrication for aluminum alloy technique, such that it is able to improve The uniformity and stability of forging process, while improving product surface quality, prevents the generation of the defects such as bark pocket.

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

A kind of lubrication for aluminum alloy technique, including following operating procedure:

The first step:Before rolling ring starts, with oiliness nano lubricating agent even application on cone roller, core roller, armful roller and workbench, Thickness is 2mm;

Second step:After rolling ring starts, it is lubricated with water nano lubricant;

3rd step:The rolling ring initial stage, control water nano lubricant spraying flow be 5ml/s, spraying position be cone roller with And the upper and lower end face of workpiece and cylindrical;

4th step:In rolling ring mid-term, when workpiece carries out radially expanded, the spraying flow for controlling water nano lubricant is 30ml/s, it is the cylindrical and upper and lower end face corner angle for embracing roller and workpiece to spray position;

5th step:In rolling ring latter stage, the spraying flow of water nano lubricant is 10ml/s, sprays position for the outer of workpiece Circle;

6th step:During whole rolling ring, if shinny region of turning white occurs in surface of the work, concentration is carried out to the region The spraying of water nano lubricant.

Beneficial effects of the present invention are as follows:

The present invention is during aluminum alloy forged, and coefficient of friction is big, increases lubrication technology, is not result in local friction and leads Cause workpiece temperature too high, advantageously ensure that interiors of products tissue and final mechanical property.Because aluminium alloy adhesiveness is big, easily glue Equipment surface is attached to, causes workpiece peeling, increase lubrication technology, be conducive to reducing the adhesion of aluminium alloy, improve workpiece final Surface quality.The improvement of surface quality, is conducive to the stability of whole rolling ring process.

Specific embodiment

With reference to the specific embodiment of the explanation present invention.

The lubrication for aluminum alloy technique of the present embodiment, including following operating procedure:

The first step:Before rolling ring starts, with oiliness nano lubricating agent even application on cone roller, core roller, armful roller and workbench, Thickness is 2mm;

Second step:After rolling ring starts, it is lubricated with water nano lubricant;

3rd step:The rolling ring initial stage, control water nano lubricant spraying flow be 5ml/s, spraying position be cone roller with And the upper and lower end face of workpiece and cylindrical;

4th step:In rolling ring mid-term, when workpiece carries out radially expanded, the spraying flow for controlling water nano lubricant is 30ml/s, it is the cylindrical and upper and lower end face corner angle for embracing roller and workpiece to spray position;

5th step:In rolling ring latter stage, the spraying flow of water nano lubricant is 10ml/s, sprays position for the outer of workpiece Circle;

6th step:During whole rolling ring, if shinny region of turning white occurs in surface of the work, concentration is carried out to the region The spraying of water nano lubricant.

It is easy to operate.

Above description is explanation of the invention, is not the restriction to inventing, and limited range of the present invention is referring to right Require, within protection scope of the present invention, any type of modification can be made.
