Abstract

PURPOSE:To manufacture a member having cross-sectional odd shape with high efficiency and low consumption of energy with a simple equipment by which a material is pressed using a specific grooved roll permitting width deformation but restraining longitudinal extension of the material. CONSTITUTION:An upper roll 3B is soroban-shaped ball with gentle inclination having projecting and recessing parts 8 on both conical side surfaces in near axial direction arranged with equal angle each other. A lower roll 4B is provided with parallel projecting and recessing parts 9 on its surface in the axial direction. The material to be rolled is heated to a temperature in which it is easily hot rolled in a heating furnace and bitten between the upper and lower rolls to be rolled. When the material is rolled, the width deformation of material is permitted but slip of the material and rolls is prevented and the longitudinal moving of the part of material in the vicinity of its surface is restrained by projecting and recessing parts 8 and 9 on the upper and lower rolls in the axial direction. Thus waving of material is little since longitudinal extension is restrained. Further, number of rolling is decreased.

2. Description of the Related Art For example, in the case of manufacturing a bar steel having a shallow groove that is deepened from both edges toward the center by rolling, conventionally, hot rolling was performed by using a rolling roll as shown in FIG. There is. That is, the upper roll (3A) in the shape of an abacus ball with a gentle inclination that is driven to rotate by force.
And the lower roll (4A) having the flanges (41, 42) on both sides, the rolled material (1) is bitten into it to form a cross section defined by the profiles of the upper and lower rolls.

In the hole rolling of FIG. 1, the amount of deformation differs depending on the position of the material in the width direction. The thin portion at the center has large rolling deformation, and the thick portions on both sides have zero rolling deformation.
For this reason, the thin portion greatly extends in the length direction of the material, and a rolled material undulating in the length direction is formed. In order to avoid this, a large rolling reduction is not performed at a time and the rolling reduction rate is 3 ~.
Deformation of about 10% is accumulated, and if necessary, the material to be rolled is reheated.

In such rolling, it is first necessary to prepare a large number of hole type rolls having different profiles.
Moreover, products with irregular cross-sections are often produced in small quantities in a wide variety of products such as turbine blades made of heat-resistant steel, titanium seawater sluice screens, titanium-containing aircraft sashes, etc., and roll costs are extremely high. I have a worry that I will do it.

A similar problem is encountered with the production of profiled rings by the rotary ironing spinning method as shown in FIG. In FIG. 2, a ring (2) is attached to a mandrel (6A) that has a flange (61) and is driven to rotate.
The inside of the ring is brought into contact, and the outside of the ring is provided with a spinning roll (5A) which is partially brought into contact therewith and is rotatable,
By rolling the ring (2) between the mandrel (6A) and the spinning roll (5A) while forcing the latter in the width direction as indicated by the arrow, the ring thickness is sequentially increased from right to left in FIG. To decrease. (7)
Is an induction heating coil for maintaining the ring at the hot working temperature.

In such processing, the rolling reduction per pass may be within the ductility range of the material, and if the material has good workability, it is about 60% in cold working and about 15 in hot working. Even when the pressure is reduced to%, the pressure-reduced portion of the ring does not extend in the circumferential direction but only in the width direction, and a deformed cross-section ring with good shape accuracy is obtained. However, in the hot working of the difficult-to-machine material, the reduction ratio is less than 15%, and the number of passes must be increased, so that the working time becomes long and the electric power required for the induction heating for preventing the temperature drop during that time becomes enormous. .

Since the rolled material obtained by the above rolling has the groove of the roll transferred to the surface and is usually unsuitable for the final use as it is, in many cases, the rolling using the group of grooved rolls is not succeeded. Thus, it may be necessary to include a finish rolling with a set of finishing rolls having an irregular cross-sectional profile but a smooth surface to obtain a smooth surface similar to the conventional one.

The apparatus shown in FIGS. 3 and 4 is one in which the present invention is applied to the rolling equipment corresponding to the hole rolling roll of FIG. As shown in FIG. 3, the upper roll (3B) is in the shape of a gently sloping abacus ball, has concavities and convexities (8) that run substantially concentrically on the conical surfaces on both sides, and are arranged at equal angles to each other.

The material to be rolled is heated in a heating furnace to a temperature suitable for hot working and is rolled between the upper and lower rolls. Upon rolling, the unevenness of the upper and lower rolls in the axial direction allows deformation of the material in the width direction, but prevents slippage between the material and the roll and restricts movement of parts near the surface of the material in the longitudinal direction, As a result, since the elongation in the longitudinal direction is suppressed, the rolled material is less likely to wavy.
