Abstract

The utility model relates to a ceramic roller mould, which comprises a support, wherein the outer side surface of the support is fixedly connected with at least one outer roller, the outer roller is driven by the support to roll and form a rolling plate, because the outer roller is arranged into a ceramic piece, the support is arranged into a metal piece, thereby the rolling speed of the mould is 2-3 times of that of a metal roller, the production efficiency is increased, and the cost of rolling pieces is reduced. When in hot rolling, a circulation hole in the support is communicated with cooling liquid, thereby reducing the temperature of the outer roller, and prolonging the service life. The rolling speed of using an existing metal roller is 150-200m/min, and the quality of rolling pieces also can be achieved to the design demands in use after the rolling speed is increased to 300-400m/min through testing.

Description

The ceramic roll mould

Technical field

The utility model relates to the rolling-bending forming that a kind of adaptation is used for rolling copper or aluminum component, the ceramic roll mould of shaping.

Background technology

In industrial production, the brake forming rolled parts is widely used at present, so rolling-bending forming, shaping roller mold are a very important equipment; And existing roll all is a metalwork, existing steel alloy or the hard alloy steel of all being to use made roll, it on metal rolled product the existence of oxide and its hardness is increased, after using 50-100 hour, roller surface is worn and torn gradually, make metal roll appearance and size precision not reach designing requirement, thereby the metal roll can not be re-used and scrap; Simultaneously because roll and the easy adhesion of rolled parts, be prone to fluff formation metal oxide thereby make on the outer surface of metal roll, again rolled parts is abraded, influenced the surface quality of rolled parts; The goods spare cost that uses the metal roll to produce is higher relatively, maintenance precision and surface anticorrosion inconvenience thereof.

Summary of the invention

The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to use, production efficiency is high, cost is low, rolling-bending forming, ceramic roll mould that the shaping parts quality is good.

For achieving the above object, the utility model adopts following technical proposals:

A kind of ceramic roll mould comprises supporter, is fixedly connected with at least one outer roll on the described supporter lateral surface.

The outer contour of described outer roll is corresponding with the curve that rolls plate that needs brake forming.

Described outer roll is formed by ceramic material.

Described supporter is a metalwork, is provided with circulation port in the supporter.

Adopt screw or bolt or pin key or bearing pin or taper fit between described outer roll and the supporter or expand with heat and contract with cold or splicing or welding or interference fit joint mode are fixedly connected.

Outer roll of the present utility model is rolled moulding to rolling plate under the drive of supporter, because outer roll is set to ceramic body, supporter is set to metalwork, and making its mill speed is 2-3 times of metal roll, therefore improve production efficiency, reduced the cost of rolled parts.When carrying out hot rolling, the circulation port in the supporter is communicated with cooling fluid, lowered the temperature of outer roll, prolonged service life.

The utility model is tested, had now and use the mill speed of metal roll to be 150-200m/min, when using the utility model, find that the quality of rolled parts also can reach designing requirement after mill speed is brought up to 300-400m/min.

The characteristics of the utlity model has down:

1, the hardness of existing metal roll generally is HRC58-62, and the hardness of ceramic roll is HRA92.5-94.5, has surpassed the hardness number of metal oxide, has reduced the wear extent of roller mold, has prolonged the service life of roll;

Simultaneously ceramic roll also can operate as normal under 1200-1450 ℃ hot environment, has improved heat resistance, has also prolonged the service life of roll;

Except that hydrofluoric acid, other inorganic acid does not produce corrosion to ceramic roll, has improved antioxygenic property, can make ceramic roll keep the appearance and size precision in different environment, has prolonged the service life of roll yet.

2, because ceramic roll is that process is by sinter molding after the particle pressing of Nano grade or the DB that forms through oversintering in pressure vessel, different with the melting or the Forging Technology of metal material, surface oxidation or hot spot can not occur, improve the surface quality of roll; Simultaneously in sintering process, can obtain with the boron nitride crystal is the pottery of matrix, and boron nitride crystal to be hexagonal have graphite-structure, make roll have good self-lubricating property; Reduced the factor of influence, improved the surface quality of rolled parts the surface quality of rolled parts.

3, owing to used pottery, reduced rolling-bending forming goods cost, alleviated the weight of roll, convenient transportation and use.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1,2,3,5,6 is monomer supporter 1 and the outer roll 2 composite unit structure form schematic diagrames of monomer; Fig. 4,7 is monomer supporter 1 and two outer roll 2 composite unit structure forms; Fig. 8 is the monomer supporter 1 and the version of outer roll 2 assemblys more than 3 or 3.Supporter 1 mostly is single component greatly, and outer roll 2 can be a slice or multi-disc compound mode and supporter 1 formation a slice roll stacks zoarium.

Outer roll 2 of the present utility model can be for being the ceramic body of material with the alumina base; It perhaps is the ceramic body of material with nitride silicon based; It perhaps is the ceramic body of material with silicon carbide-based; It perhaps is the ceramic body of material with the zirconia base.Outer roll 2 is split type ceramic body, is convenient to the sinter molding of outer roll 2.

Adopt screw or bolt or pin key or bearing pin or taper fit between outer roll 2 and the supporter 1 or expand with heat and contract with cold or splicing or welding or interference fit joint mode are fixedly connected.

The outer contour of outer roll 2 is set to the curve corresponding with rolling plate, and outer roll 2 is rolled moulding to rolling plate under the support of supporter 1.

When carrying out test of the present utility model, because outer roll 2 is set to ceramic body, supporter 1 is set to metalwork, and by a large amount of tests, the connecting mode of employing pin key and bonding agent makes the better effects if of fixedlying connected between outer roll 2 and the supporter 1.

The utility model is tested, and has now to use the mill speed of metal roll to be 150-200m/min, when using ceramic roll, finds that the quality of rolled parts also can reach designing requirement after mill speed is brought up to 300-400m/min.
