Description of the Related Art Conventionally, rolled screw processing in a plate-shaped connection conductor with a thread, which is a plate-shaped conductor partially formed with a thread groove, which is conventionally used as an electric circuit component, is usually performed by using a mold. Is going. By the way, a predetermined screw torque force is required as a product in such a threaded plate-shaped connection conductor. However, for example, the work thickness of such a plate-shaped connection conductor is thin, and therefore, it is required as a product. When the demand for the screw torque force is not satisfied, for example, burring is used as one means to secure the effective number of threads, thereby satisfying the required screw performance.

満たす場合であることは言うまでもない。[0003] On the other hand, the thickness of the product cannot be increased due to the function of the product, so that the number of threads specified for the screw diameter may not be secured. Then, for example, processing as shown in FIG. 4 was performed. That is, first, as shown in FIG. 5 (a), only the drilling of the prepared hole of the female screw is performed by using a mold, and then,
In another step, as shown in FIGS. 5B and 5C, a chamfered portion is formed in the opening of the prepared hole in the front surface and the back surface of the workpiece, and further, a cutting process is performed and a tapping is performed. ing.
However, it goes without saying that these are cases where the required screw torque force of the product is satisfied.

りを逃がすための形状を形成させる必要が生じてくる。However, according to the prior art as described above, the thickness of the workpiece is small, so that a plate-shaped connection conductor in which a specified number of threads cannot be secured is required. However, in the case of forming a thread groove by performing cutting after the above-described rolling, the obtained torque force is still low, so that the expected performance required for the product can be satisfied. Not what happens. In addition, as shown in the attached FIG. 6, there is a problem that the flatness around the female screw 1a and 1b is impaired by the bulge 1a formed after the rolling process, and the quality of the product is deteriorated. . As a countermeasure, it is necessary to form a shape for releasing the above-mentioned bulge in advance on the front and back surfaces of the workpiece by using a spot facing shape or the like.

れ、これにより、トルク力も確保できることとなる。[0005] From this fact, the number of threads is further reduced,
For this reason, it has been considered that, in particular, when the thickness of the workpiece is small, the rolling process using the mold cannot be practically used. Further, if the screw processing of the plate-shaped connection conductor is performed by cutting, the bulging amount of the female screw is smaller than that of the above-described rolling processing, and therefore, the relief shape of the bulging can be reduced, and accurate As a result, a mountain shape is obtained, so that a torque force can be secured.

It is a factor that causes the damage of the material, so that its practical use has been difficult. Therefore, conventionally,
Since the screw processing is performed in a separate process, there is a problem that a lot of man-hours and labor are spent.

The reference numerals 14a and 14b) are set to the following values. That is, the amount of dent in the first processing step is determined on the assumption that the work
