品質が著しく低下する。The long metal plate manufactured by the above mold apparatus is annealed in an annealing furnace and shaped by a rolling machine and then cut, for example, and used as a contactor of a connector. However, it was not possible to continuously process the long metal plate formed by the die device and coming out as it is in the annealing furnace or the rolling mill. In other words, the metal material is sent by intermittent movement in the mold device, and the metal material is sent at a constant speed in the annealing furnace or rolling mill, so the material movement speeds do not match, and therefore the metal material sent from the mold device is The material is wound on a coil with the interleaving paper in between, and when it is processed in a rolling mill or an annealing furnace, it is necessary to unwind the coil, reprocess it, and then rewind it into the coil, which takes time and wastes the interleaving paper. Occurs. If the metal material coming out of the die device is directly processed by a rolling mill, the plate thickness and width of the metal material will fluctuate, and traces of intermittent feed will be attached to deteriorate the appearance, resulting in a marked deterioration of product quality.

圧延機を接続できない。In the case of molding a modified cross-section plate continuously molded by the mold device, the frequency of intermittent feeding is 6 to 10 Hz,
When winding a molded metal material having an irregular cross section, for example, as shown in FIG. 5, the speed change within one cycle of the frequency is 0.2 to 3.9 m / min, and the tension change is 500 to 75.
It varies in the range of 0 kgf. Therefore, it is not possible to connect an annealing furnace or a rolling mill, which requires the supply of the material at a substantially constant speed and a constant tension, to this mold device.

点がある。It is possible to degrease a long metal material that has been molded by the mold apparatus with a solvent such as freon or trichloroethane, but the use of these chemical agents is not preferable because it causes environmental damage. Further, when degreasing is performed by pickling, there is a drawback that management of waste acid treatment is troublesome and cost is high.

ができる。When the long metal material that is in contact with the plate surface of the mold of the mold device is in a stopped state, the pressing roll rolls in the range of the plate surface and presses the metal material against the plate surface. Each time the rolling is completed, the moving device moves the metal material by a certain distance, and by repeating this, the metal material is gradually formed into, for example, a deformed cross-section plate having a thick portion and a thin portion.
Since the metallic material is sent out from the die device by intermittent movement, if it is left as it is, it is sent continuously to an annealing furnace and a molding machine that process the material coming out of the die device while moving the metal material at a substantially constant speed. However, in the present invention, an intermittent feeding device is provided at the rear of the mold device, and when the metallic material is intermittently fed out from the mold device, this intermittent The oscillating roll of the feeding device is oscillated by the spring, and it becomes possible to continuously pull and move the long metal material with a moving device at a substantially constant tension and a constant speed. It is possible to directly connect an annealing furnace that needs to be controlled at a substantially constant speed and constant tension.

When the metal material to which this adheres is annealed in a continuous annealing furnace, there arises a disadvantage that discoloration occurs, but a heating degreasing furnace having a low temperature extension is provided at the inlet of the continuous annealing furnace, and the outlet side of the continuous annealing furnace. Since the flow of the gas discharged to the outside through the chamber, the chamber of the heating and degreasing furnace, and the inside of the extension, the metal material to which the rolling oil adheres is transferred from the die device to the intermittent feeding device and the heating and degreasing furnace. Even if it is continuously annealed by passing through an annealing furnace, the rolling oil adhered to the metal material is evaporated in the heating degreasing furnace, and the evaporated oil is caused by the flow of the gas. It is discharged to the outside without entering the chamber of the continuous annealing furnace, the gas and the evaporated oil are separated in the extension portion having a relatively low temperature, and are discharged from the exhaust port and the exhaust port, respectively. When the metal material is heated for annealing in the continuous annealing furnace, the metal material is substantially completely degreased, and the metal material formed by the mold device can be continuously subjected to heat degreasing and annealing. Therefore, the workability is good, and the discharged oil can be collected and reused.

The long metal material thus formed can be continuously subjected to degreasing, annealing, and shaping steps.

It is performed only when the pressure rolling of the pressure roll 3 for pressing the metal material 1 against the plate surface 2b is completed and the pressing is released. Since the rolls 10 and the rocking rolls 13 are alternately provided between the mold device 2 and the heating degreasing furnace 4, the press rolling of the pressing roll 3 for pressing the plate surface 2b of the mold 2a is completed. When the tension of the metal material 1 is about to be relaxed,
The spring 12 moves the oscillating roll 13 away from the space 11 of the rolls 10 to maintain the tension, and the metal material 1 is not fed out from the mold device 2 during the pressure rolling of the pressure rolls 3. , The tension tends to increase, but at this time, the rocking roll 13 resists the spring 12 and the gap 1
It moves so as to approach 1 to prevent the increase in tension. Therefore, the metal material 1 can be intermittently moved in the mold device 2, and the metal material 1 can be continuously moved at a substantially constant speed in the subsequent thermal degreasing furnace 4. More specifically, as described above, the intermittent movement of the metal material 1 in the mold device 2 is 6
When the frequency is about 10 Hz, the speed / tension changes shown in FIG. 5 within one cycle of the frequency. At this time, the rocking roll 13 vibrates in response to the rapid speed change, and the metal material 1 When the pressure of the pressure roll 3 rapidly increases due to the completion of the pressure rolling of the pressure roll 3 and the tension starts to decrease, the rocking roll 11 is moved so as to store the metal material 1 from the position A in the arrow direction as shown in FIG. When the tension of the metal material 1 is minimized, the rocking roll 13 moves in the arrow direction from the B position until the speed becomes the next, and then the speed becomes higher. Release the reserve. The mold apparatus 2 requires a large number of rocking rolls 13 because the speed and tension fluctuations increase as the processing speed increases, but if the speed is about 10 m / min, the mold device 2 shown in FIG. So you only need two. The oscillating roll 13 is configured as a vibration system having a natural frequency capable of following a rapid speed change of the mold device 2, and as the spring 12, the material for the intermittent feed of the mold device 2 can be stored by displacement of the spring. Things are used. Although the tension changes due to the displacement of the spring 12, the spring constant is preferably as small as possible. The spring 12 is not limited to a pull spring, but may be a push spring.
