Abstract

The utility model discloses a ring rolling machine roller for rolling trapezoid cross section ring pieces, and belongs to a ring piece rolling mould; the ring rolling machine roller structurally comprises a driving roller and a core roller, wherein the working surface of the driving roller is provided with a groove and a V-shaped hole pattern; and the working surface of the core roller is also provided with a V-shaped groove. Compared with the prior art, the ring rolling machine roller can be used for rolling the two trapezoid cross section ring pieces for once, so that the production efficiency is improved, the raw material consumption and the processing cost are reduced, and the labor intensity is lightened; and therefore, the ring rolling machine roller has good popularization and application values.

Description

A kind of Ring Rolling Machine roll that is used for rolling trapezoid cross section ring

Technical field

The utility model relates to a kind of ring rolling mould, especially a kind of Ring Rolling Machine roll that is used for rolling trapezoid cross section ring.

Background technology

At present; The trapezoid cross section ring adopts radial rolling to add machine cut processing associating completion usually; Its driven roller and core roller are straight working face, promptly process the ring of square-section earlier through radial rolling, through machine cut the square-section ring are processed into trapezoidal rank section ring parts again; Utilize the subject matter of this roll production trapezoid cross section ring to be: (1) allowance is big, and stock utilization is low; (2) production efficiency is low, and labour intensity is big; (3) ring needs repeated heating, and energy consumption is high; (4) production cost is high; (5) once can only make a flange, utilization rate of equipment and installations is low.

Summary of the invention

The technical assignment of the utility model is to the deficiency in the above-mentioned technology a kind of Ring Rolling Machine roll that is used for rolling trapezoid cross section ring to be provided; This roll can once rolling two trapezoid cross section rings; Improved production efficiency; Reduce raw materials consumption and processing charges, reduced few labour intensity, practiced thrift the production time.

The utility model solves the technical scheme that its technical problem adopted: it comprises driven roller and core roller, and described driven roller working face is provided with groove and V-shape hole type, and core roller working face is provided with v-depression.

Described driven roller and core roller groove, it highly is equal to the finished product ring height 2H of twice, and the driven roller recess width equals finished product ring end face width B, and groove shapes and finished product ring cross section are complementary.

The Ring Rolling Machine roll that is used for the trapezoid cross section ring rolling of the utility model compared with prior art has following outstanding advantage: rolling two trapezoid cross section rings simultaneously, reduced raw materials consumption and processing charges; Improved production efficiency; Save the production time, used semiclosed pass, improved the end face quality; Easy to use, simple in structure.

The specific embodiment:

With reference to explanation at length below the Ring Rolling Machine roll work that is used for the trapezoid cross section ring of Figure of description 1 and 2 pairs of the utility model of accompanying drawing.

Its structure of Ring Rolling Machine roll that is used for the trapezoid cross section ring rolling of the utility model comprises driven roller and core roller, and described driven roller working face is provided with groove and V-shape hole type, and core roller working face also is provided with v-depression.

Described driven roller and core roller groove; It highly is equal to the finished product ring height 2H of twice, and the driven roller recess width equals finished product ring end face width B, and groove shapes and finished product ring cross section are complementary; Make that the forging shape that machines is accurate, following process is less.

The concrete course of work of Ring Rolling Machine roll that is used for the trapezoid cross section ring rolling of the utility model: under the straight-line feed motion effect of rolling motion of the rotation of driven roller and core roller; The ring blank rolling groove that driven roller and core roller constitute of nipping continuously; The generation wall thickness reduces; Inner and outer diameter enlarges, the continuous local plastic distortion that cross section profile is shaped.Along with carrying out rollingly, the ring cross section progresses into pass, and when rolling end, the ring cross section gets into pass fully, helps ring end face quality.Before the rolling beginning, ring blank accurate location in pass be guaranteed, good lubricated and cooling be guaranteed.

Claims (2)

1. A ring rolling machine roll for rolling trapezoidal cross-section rings, the structure includes a drive roll and a core roll, and it is characterized in that: the working surface of the drive roll is provided with grooves and V-shaped passes, and the core roll V-shaped grooves are arranged on the working surface. 2. The ring rolling machine roll for rolling trapezoidal cross-section rings according to claim 1, characterized in that: the grooves of the driving roll and core roll have a height equal to twice the height 2H of the finished ring , the groove width of the driving roller is equal to the width B of the end face of the finished ring, and the shape of the groove matches the section of the finished ring.
