Description

  The present invention relates to a caulking aid, and more particularly, to a caulking aid for temporarily securing a caulking stopper member to a caulking receiving member prior to caulking a caulking stopper member having a caulking stopper portion with a die member.

  In the case where a caulking stopper member having a caulking stop portion, for example, a caulking stopper pin, is formed by pressing or bending and is formed of an aluminum plate or the like and having caulking holes, for example, the first is a conventional method. Then, the operator fits the caulking stop pin into the caulking hole. Next, the caulking punch is placed near the caulking hole while the caulking stop pin is fitted in the caulking hole. Next, if a finger or the like is applied to the caulking stop pin, the finger is removed from the caulking stop pin, and the caulking punch is quickly applied to the caulking stop pin to perform caulking.

  As another prior art, even if the caulking plate (caulking receiving member) is not accurately caulked, the caulking stopper pin is fixed by a positioning pin installed at an accurate position in the caulking jig. There has been proposed a press machine that performs caulking processing in position (see, for example, Patent Document 1).

  As another prior art, in a caulking machine, a telescopic workpiece pressing member extending downward from the caulking hammer is provided at the tip of the caulking hammer, and the caulking stop pin is pressed against the workpiece prior to caulking with the caulking hammer. There has been proposed a configuration in which a position is fixed by pressing with a member so as not to be displaced, and a caulking stop pin is caulked thereon (for example, see Patent Document 2).

  In the above-described conventional technique in which the upward caulking pin is pressed with the finger and the caulking process is performed, skill is required to quickly remove the finger and hold the caulking pin with a caulking press before the caulking pin drops. However, if the finger is not removed in a timely manner, there is a problem that the caulking stop pin falls, and this technique is inefficient and unstable.

There is a problem that the caulking stop pin is likely to come off from a predetermined position before the caulking stop pin is pressed by the workpiece pressing member.
In the press machine of Cited Document 1, the caulking jig must be held in a predetermined position even in the caulking process, and there is a problem that the caulking jig is difficult to perform the caulking process. Further, since the caulking jig does not have a function of fixing to the work plate (caulking receiving member), it is difficult to fix the caulking jig to the work plate (caulking receiving member) during the caulking prevention process. is there.

  In the caulking machine of the cited document 2, there is a problem that the caulking stopper pin is likely to come off a predetermined position before the caulking stopper pin is pressed by the workpiece pressing member. Although this problem can be solved by continuing to press the caulking stop pin with a finger or the like before pressing the caulking stop pin with the workpiece pressing member, such a work procedure is not allowed for safety.

(Purpose of the idea)
The present invention has been made in view of the above-described problems of the prior art, and is capable of performing caulking prevention processing while maintaining the caulking prevention pin at a predetermined position of the caulking receiving member with high accuracy and reliability. The object of the present invention is to provide a caulking aid that is simple and can be used even in a narrow space.
