を目的とする。However, in the above-mentioned parts, the selection of the plate thickness is strict due to the weight, strength and the like. Therefore, it is necessary to use the selected specified thickness of the steel plate, which is costly. There was a problem of rising prices. Further, the ordinary strip steel sheet is appropriately hot-rolled, but the degree of working is not sufficient, and there is a problem that the strength may be insufficient when tested in a relatively soft manner. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method for processing a pressed product that enables effective use of materials and that also improves the strength of the product.

The method for processing a press product described is a method for processing a press product using a strip-shaped thin plate as a raw material, and a rolling device is arranged immediately before the pressing device, and the strip-shaped thin plate unwound from the coil,
Cold rolling is performed in the length direction by the opposing rolling rollers of the rolling device to make the thickness constant, and work hardening is given to the strip thin plate, and press working is performed by the subsequent pressing device.

る。In the method for processing a pressed product according to claim 1, since the strip-shaped thin plate is used as the original plate material and is rolled to a constant thickness in the length direction by the opposing rolling rollers, the lateral elongation is reduced, The elongation in the depth direction becomes large. Therefore, the substantial length of the material is increased, and the effective utilization of the material is improved. Then, since the strip-shaped thin plate is rolled in the length direction, work hardening occurs in the material, and as a result, the strength of the product is improved.

Here, FIG. 1 is a schematic side view showing a method for processing a pressed product according to an embodiment of the present invention.

によって、その加圧力を調整できるようになっている。As shown in FIG. 1, a coil 10a of a strip-shaped thin plate 10 having a predetermined width (usually within 200 mm) wound a little thicker than the product material is prepared, and a coil 10a is provided with a certain degree of bending to form a pair. It is nipped and conveyed by the feed roller 11, and the strip-shaped thin plate 10 is cold-rolled to the product material thickness by the opposing rolling rollers 12 and 13. Thereby, the strip thin plate 10
Is rolled and greatly stretched in the longitudinal direction. The rolling device 14 including the rolling rollers 12 and 13 includes a pressing device 17
A cylinder 15 which is arranged immediately before and is provided as an example of a pressing means on the upper part, and the pressing force of the cylinder 15 can be adjusted to adjust the pressing force.

の曲がり癖を矯正するものである。Then, the rolled strip-shaped thin plate 10 is conveyed to the pressing device 17 via the leveler 16a and the feed roller 16 arranged at the rear portion of the leveler 16a. A motor (not shown) is provided on each of the feed rollers 11 and 16 so as to gradually convey the strip-shaped thin plate 10. However, the strip-shaped thin plate 10 on the exit side of the rolling device 14 is provided.
Since the sheet is stretched, the feed roller 16 can feed the strip-shaped thin plate 10 at a correspondingly high speed. The leveler 16a has a well-known structure, and the strip-shaped thin plate 10
It is to correct the bending habit.

くなる。Further, the band-shaped thin plate 10 undergoes work hardening as it passes through the rolling device 14, which increases the strength of the pressed product by about 10 to 20%. When the strip-shaped thin plate 10 is rolled, it is slightly stretched in the width direction within a range of 1% of the entire width, but is greatly stretched in the length direction of 10 to 13%, so that the material yield is improved.

スペースで処理を行うことができる。As is apparent from the above description, in the method for processing a pressed product according to the first aspect of the present invention, the strip-shaped thin plate is rolled by the opposing rolling rollers. Yield is improved. Further, since the strip-shaped thin plate undergoes work hardening by rolling, the strength of the pressed product is improved. Since the thickness of the rolled strip-shaped thin plate is determined by the rolling roller, even if there is a variation in the thickness of the original plate material within a rollable range, the thickness can be precisely adjusted and is relatively high. There is no need to purchase an expensive strip-shaped plate with a specified thickness, which is economically advantageous. Further, according to the present invention, the surface roughness of the strip-shaped thin plate is improved, and the plate material having a dense and smooth surface is obtained. Further, since the rolling device is arranged immediately before the pressing device and the treatment is continuously performed, there is no intermediate product such as a coil rolled to a constant thickness and the treatment can be performed in a narrow space.
