ヤツプの加工装置である。 The present invention has been made in an attempt to eliminate such deficiencies. That is, in a processing device for a metal screw cap, in which a side wall hangs down from an upper wall, and a thread is formed on the folded line of the cap material, which is formed with a folded line extending inwardly and upwardly from the lower end of the side wall, one end is connected to a rotary drive device. A screw thread is provided on the circumferential surface of the other end of the inner mold connected to the cap support, a recess substantially matching the outer shape of the cap material is provided in the cap support, and the other end of the inner mold is connected to the cap support. A processing device for a metal screw cap, characterized in that a support pressing tool which can be freely inserted into the recess and whose one end is connected to a rotary drive device is arranged so as to press the circumferential outer surface of the cap support. .

結されている。 The present invention will be explained below based on an embodiment shown in FIGS. 5 and 6. In the figure, the same reference numerals as in the conventional example indicate the same parts. Reference numeral 5 denotes a cap support, which is rotatably provided with a recess 5a that substantially matches the outer shape of the cap material 4'. Reference numeral 6 denotes a support pressing tool, one end of which is connected to a rotational drive device (not shown).

る。 Then, the cap material 4' is attached to the cap support 5.
into the recess 5a. Since the outer shape of the cap material 4' substantially matches the recess 5a, the cap material 4' is placed within the recess 5a. Next, the other end surface 1b of the inner mold 1 is inserted into the cap material 4' and comes into contact with the inner surface of the cap upper wall 4a. Since the inner mold 1 is rotating, the cap material 4' and the cap support 5 are also rotating. Thereafter, by pressing the circumferential outer surface of the cap support 5 while rotating the support press tool 6, the bent edge 4c of the cap is formed at the internal thread 1a.
A screw thread 4d is formed on the screw cap 4, and the screw cap 4 is completed.

４ｂが変形することなく、精度の高いねじ４ｄが
形成できる。 According to this processing device, the support pressing tool 6 is pressed against the circumferential outer surface of the cap support 5, and force is applied to the cap material 4' via the cap support 5, so that a force is applied to the cap material 4' on the cap side wall 4a. No local force is applied directly. Therefore, the screw 4d with high precision can be formed without deforming the cap side wall 4b.
