Background

In the process of hot rolling and processing the deformed steel, due to the complex and asymmetric profile of the deformed steel and the like, the upper and lower hot-rolled rolls are subjected to axial force action besides radial force and can move along the axial direction, so that the hole pattern is deformed, and waste products are caused. As shown in fig. 1, when the deformed steel is rolled, the upper roller 1-1 and the lower roller 1-2 generate axial force due to the asymmetry of the profile of the deformed steel, the upper roller 1-1 and the lower roller 1-2 move left and right (as shown by arrows in fig. 1, the upper roller is forced to move left, and the lower roller is forced to move right), the profile of the deformed steel pass 1-4 is deformed, and waste products are generated, as shown in fig. 2(a) is a normal pass, and fig. 2(b) is an abnormal pass).

In order to solve the technical problems, a special-shaped steel rolling roller which is axially fixed in the rolling process needs to be designed to ensure the relative positions of the upper roller and the lower roller.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a rolling abnormal shape steel roll guarantees the relative position of upper and lower roll through rolling mill locking device, and product quality improves, and the lumber recovery improves.

In order to achieve the above object, the utility model provides a following technical scheme:

a special-shaped steel rolling roller comprises an upper roller and a lower roller, a special-shaped steel rolling hole is formed between the upper roller and the lower roller, a process ring is arranged between the upper roller and the lower roller, the special-shaped steel is arranged in the special-shaped steel rolling hole during rolling, and the maximum axial force borne by the process ring is larger than the axial force generated during rolling of the special-shaped steel.

The process ring comprises a circle of process annular groove arranged on the upper roller and a circle of process annular protrusion arranged on the lower roller, and the process annular protrusion is inserted into the process annular groove.

Furthermore, two sides of the process annular bulge are in wedge-shaped fit with the process annular groove through inclined planes.

The special-shaped steel rolling device comprises an upper roller, a lower roller and a special-shaped steel rolling hole, wherein the upper roller is provided with an upper hole matched with the upper surface of the special-shaped steel, the lower roller is provided with a lower die matched with the lower surface of the special-shaped steel, and the special-shaped steel rolling hole is formed between the upper hole and the lower die.

Wherein, the both ends of going up the roller all are equipped with locking ring.

Wherein, both ends of the lower roller are provided with lower locking rings.

The utility model discloses an above-mentioned technical scheme's beneficial effect as follows:

in the above scheme, utilize the utility model discloses product contour dimension after the rolling is stable, and the quality improves. Use the utility model discloses a rolling mill equipment atress reduces, and the life-span extension, the yield improves. The utility model is suitable for a rolling various deformed steel products.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

The utility model discloses upper and lower roll has axial motion easily when rolling to current abnormal shape steel, and the yielding problem of abnormal shape steel pass provides a rolling abnormal shape steel roll.

As shown in fig. 3, the embodiment of the utility model provides a rolling deformed steel roll, including last roller 1 and lower roller 2, it is equipped with deformed steel rolling hole 4 to go up between roller 1 and the lower roller 2, it is equipped with the last hole that matches with the upper surface of deformed steel on the roller 1 to go up, be equipped with the lower mould that matches with the lower surface of deformed steel on the lower roller 2, form between last hole and the lower mould deformed steel rolling hole 4.

A process ring 3 is arranged between the upper roller 1 and the lower roller 2, the deformed steel is placed in a deformed steel rolling hole 4 during rolling, and the maximum axial force which can be borne by the process ring 3 is larger than the axial force generated during rolling of the deformed steel.

The process ring 3 comprises a circle of process annular groove arranged on the upper roller 1 and a circle of process annular bulge arranged on the lower roller 2, and the process annular bulge is inserted in the process annular groove.

The two sides of the process annular bulge are in wedge-shaped fit with the process annular groove through inclined planes. In this embodiment, the process annular protrusion is designed to have a trapezoidal cross section.

As shown in fig. 4, both ends of the upper roll 1 are provided with upper locking rings 5. And lower locking rings 6 are arranged at two ends of the lower roller 2.

The use process of the special-shaped steel rolling roller of the utility model is described in detail as follows:

the upper roller 1 and the lower roller 2 are installed, so that the process annular bulge is inserted into the process annular groove, a special-shaped steel rolling hole 4 with a normal hole pattern is formed between a lower die on the lower roller 2 and an upper hole on the upper roller 1, the special-shaped steel is placed in the special-shaped steel rolling hole 4, the upper roller 1 and the lower roller 2 are started, no axial movement exists between the upper roller 1 and the lower roller 2 due to the existence of the process ring 3, and the special-shaped steel is rolled and formed in the special-shaped steel rolling hole 4.
