Abstract

PURPOSE:To elevate the efficiency in work process by performing the punch formation alignment with the tapered face interference by the descent of the upper die guide chamfering of the upward chamfer of a freely placed body to be worked in the adverse taper forming work of a spline piece. CONSTITUTION:The body W to be worked is freely placed on the projection 18 of a lower die plate 19 in the reverse taper formation of the spline piece of the gear clutch of a gear speed changer. The upward chamfer 2 thereof is fitted with alignment by making respective tapered face 2a interface with the descent of the chamfering 17 of the hollow guide 13 of the upper die 10. The work efficiency in the work process is elevated with the automation of the position setting of a reverse taper forming tool. The work is made more efficient with combining the guide hollow part with a descending reverse taper work punch 4 after the position setting.

In such a reverse taper forming process, a workpiece on which a chamfer and straight spline teeth have been formed is set in a mold with the chamfer facing upward, and in this state, the workpiece is pushed down with a punch so that the chamfer is downward. A reverse taper is formed on the spline teeth using a mold. Therefore, in the first stage of this process, with the chamfer facing upward, the circumferential phase of the workpiece is aligned so that its spline teeth are positioned in the recesses of the mold, and its tooth grooves are positioned in the convex parts of the mold. It is necessary to set it.

On the other hand, for example, Japanese Patent Publication No. 52-35337 discloses an S-position positioning method in which the workpiece is set with the chamfer facing downward in the process of forming spline teeth. A means has been proposed that is coupled to an object and forcibly rotates and aligns the workpiece. However, according to this method, there is a risk of damaging the tip of the chamfer, and there are other problems such as the need to accurately connect the auxiliary punch and the workpiece before alignment and to accurately separate the auxiliary punch and workpiece after alignment.

Effect 1 of the invention As is clear from the above explanation, according to the phasing method of the present invention, the workpiece and the mold are automatically phased before the reverse taper forming process, which eliminates manual phasing. Phase matching is no longer necessary, and work efficiency can be improved. In addition, this method utilizes the upward chamfer of the workpiece, and first lightly contacts the chamfer door ring with the tapered surface, and then rotates the workpiece with a component force in the circumferential direction. It is preferable to assemble the phasing means to the reverse taper forming device as shown in the embodiment shown in Fig. 5, since there is no need to consider unreasonable force or run-off. Misalignment is eliminated and accuracy is improved.
