Abstract
A general combined roller for a roller type cross wedge rolling mill belongs to the field of engineering components and is characterized in that: the wedge-shaped die fixed on the roll shaft body consists of a wedge-shaped template, a stop block, a plurality of cushion blocks, a pressing block and a plurality of double-threaded screws. The method has the advantages of easy manufacture, low cost, reliable precision and frequent change of rolled objects, and only one element of the wedge-shaped template needs to be replaced; the minimum economic batch for a roller wedge rolling mill is only 10-20% of the other rolls used in the same mill.
Description
The utility model is the improvement that is used for the roll of cross wedge rolling mill roller, and this roll belongs to field of engineering components, is made of roller body and wedge shape mould.
In order in the working shaft-like part, to improve product precision, production efficiency and life tools, and eliminate aborning and impact and the minimizing noise, all extensively adopt a kind of cost than the cross wedge rolling machine equipment that forges low about 30% both at home and abroad at present, cross wedge rolling mill roller wherein is an exemplary apparatus of producing rolled piece product in enormous quantities.A kind of monoblock type roll that existing cross wedge rolling mill roller adopts is wedge shape mould and roller body to be made in the one circular hole and roll shaft of the rolling mill transition or taper hole assemble and close; The another kind of arc roll that adopts is that the arc module that one or a few is very thick directly is fitted on the roller body or with the arc module with the briquetting hypotenuse and directly is fixed on the roller body that has T type groove with screw and T type nut.Above-mentioned roll structure exist all the time machining allowance and difficulty big, consume alloy cast steel or the forged steel material is many, pass processing need be set up servicing unit and the extremely low shortcoming of manufacturing efficient; Particularly the difficulty of processing to pass curve and curved surface is bigger, and the instrument precision can not get guaranteeing especially.Because research expenditure height, lead time are long, the minimum economic of rolling a kind of rolled piece product is in batches all more than 20,000, and this brings obstacle for furtheing investigate the rolling new product of rolled with roller wedge technology.
The purpose of this utility model is the deficiency that exists with roll at existing cross wedge rolling mill roller and provide a kind of and save material, be easy to process, shorten research cycle, reduce roll cost and the rolled piece product minimum economic general composite (back-up) roll of repeated use type in batches.
Its solution is: roll still is made of roller body and wedge shape mould, and the axial via hole by tapering or interference fits roll shaft of the rolling mill, the axial T type groove that securing member stationary wedge mould is passed through in the external cylindrical surface setting are set at the axle position of roller body; Be fixed on wedge shape mould on the roller body and adopt the wedge shape template of the isoceles triangle arc shape be gradual change isosceles trapezoid cross section, through the plural part arc cushion block of inner arc surface and the roller body is fitted and the circumferential gradual change shape dovetail groove that the symmetry shape angle-shaped groove of briquetting formed through plural number and embed the arc prism of wedge shape template two waists, regulate spacing by the two through hole that plural part stud passes below middle part cushion block and the both sides briquetting angle-shaped groove, fastening by the screw in the counterbore in the middle part of T type slider nut and the briquetting of roller body shaft in T type groove again, the tangential spacing institute of block common combination through wedge shape template head and the tail two ends forms again.
According to the general composite (back-up) roll that such scheme is made, not only easy to manufacture, with low cost, precision is reliable, and when the rolling object of frequent changes (being the rolled piece product), only need change a kind of element of wedge shape template; When this roll is used for cross wedge rolling mill roller, its minimum economic in batches only between 2,000 to 5,000, only be cross wedge rolling mill roller use other roll 10%～20%; Promote the general composite (back-up) roll of this repeated use type aborning, have tangible economic benefit.
Accompanying drawing has been described an embodiment of the utility model structure.
Accompanying drawing 1: the axial view of general composite (back-up) roll.
Accompanying drawing 2: the radial junction composition of this roll.
Accompanying drawing 3: the three-dimensional view of briquetting (3 and 7).
Accompanying drawing 4: wedge shape template (5) structure chart.
As shown in the figure, roll is partly constituted, and is assemblied in by the axial via hole (14) on the roller body (21) on the roll shaft (23) of cross wedge rolling mill roller by roller body (21) and wedge shape mould (22) two.The wedge shape mould (22) that is fixed on the roller body (21) is the wedge shape template (5) that is the isoceles triangle arc shape in gradual change isosceles trapezoid cross section by, plural part arc cushion block (4) through inner arc surface is fitted with the roller body, and the circumferential gradual change shape dovetail groove that the symmetry shape angle-shaped groove (16) of briquetting (3 and 7) is formed through plural number and embed the arc prism (24 and 25) of wedge shape template (5) two waists, pass two side through hole (17 of middle part cushion block (4) below both sides briquetting (3 and 7) angle-shaped grooves (16) by plural part stud (8), 18) regulate spacing, fastening by the screw (2 and 6) in the counterbore (19) in the middle part of T type slider nut (1 and 9) in the axial T type groove (15) of roller body (21) and the briquetting (3 and 7) again, again through tangential spacing being combined to form of the block at wedge shape template (5) head and the tail two ends.Briquetting (3 and 7) is a kind of arc piece with certain width and thickness, and its inner arc surface is identical with the external cylindrical surface curvature of roller body (21), and exterior arc surface one side outer rim angle-shaped groove (16) has its lead angle β and spreading angle of wedge tool α.In order to simplify processing, the most frequently used spreading angle of wedge tool is got at the β angle of briquetting (3 and 7), and α gets at the angle the most frequently used wedge shape forming angle, has the through hole (17,18) by double threaded screw in the both sides, bottom of angle-shaped groove (16).Wedge shape template (5) is because more much smaller than the template thickness of arc roll, generally be by plane line planing or Milling Machine processing with thin material, and adopt cold conditions or hot bending to have the rolling mill practice pass, the outer rim shape is consistent with briquetting (3 and 7), the arc that bending radius and briquetting (3 and 7) adapt.Wedge shape template (5) spread angle β
1With forming angle α
1Identical with the lead angle β of briquetting (3 and 7) with the spreading angle of wedge tool alpha parameter.When the combination assembling, the inclined-plane, both sides of wedge shape template (5) embeds in the dovetail groove of briquetting (3 and 7) formation.Because wedge shape template (5) is thinner, for preventing notch distortion under its operation of rolling, below wedge shape template (5), the centre of briquetting (3 and 7) is equipped with plural part cushion block (4).Briquetting (3 and 7) is provided with screw (2 and 6) with counterbore (19), is fixed on roller body (21) external cylindrical surface with T type groove (15) by screw (2 and 6) and T type slider nut (1 and 9).Tangential (promptly circumferential) of wedge shape template (5) is spacing to be to guarantee by the block (11,12) that is fixed on roller body (21) external cylindrical surface with T type groove (15) with T type key nut (10) and screw (12 and 13).Double threaded screw 8 then limits the displacement to axial between the briquetting (3 and 7) in order to regulate the spacing of briquetting (3 and 7) in the operation of rolling.When the rolling object of conversion, only need the conversion can be all or most wedge shape template (5) of under flat state, finishing pass and other processing, can select for use other each independent component of combinations thereof formula roll to ressemble formation.
