Description

[Detailed Description of the Invention] [Outline] A free angle abutment tool, more specifically, a general-purpose press work, allows the work angle to be freely set when punching a long hole with an angle to the reference plane into the work. With regard to the abutting tool to be used, when punching a long hole with an angle in a work by a general-purpose press work, the work setup is simple and the accuracy can be secured, and it can be widely used for similar work. For the purpose of providing a free angle abutment that can be performed, a screw is provided near one end of a vertically long mounting bracket whose longitudinal side forms a reference surface, and slides in the left-right direction of the mounting bracket around the screw. A possible slide with angle scale was attached, and a right angle ruler abutting part was integrally connected to one end of the slide with angle scale (12) via a connecting pin, and an angle of θ was attached to the reference plane. When punching a long hole, slide with the scale An angle abutment tool having a configuration in which the angled slide is set and the scaled slide is fixed with a screw, a workpiece is brought into contact with one side of a right-angled ruler abutment portion, and a long hole is punched out. Including.

[Industrial applications]

The present invention relates to a universal angle abutment tool, and more particularly, to an abutment tool that enables free setting of the angle of a work in punching a long hole having an angle with respect to a reference surface in a general-purpose press work.

[Conventional technology]

A case of punching a long hole having an angle with respect to the reference plane by a general-purpose press work will be described with reference to an example shown in the plan view of FIG. When punching a long hole that is parallel or at a right angle to the reference surface 23 for punching the angled long hole 22, fix a spacer 24 parallel to the reference surface 23 to the mold base and use this spacer. It is possible to punch a long hole parallel to or right angle to the reference surface in a general-purpose press work without any problem simply by bringing the workpiece into contact. However, as shown in FIG. Special spacers are required to punch out angled slots.

FIG. 3 is a plan view of a conventional example, in which 25 is a die stand. An angled spacer 26 is fixed to the table 25, and a long hole 22 is formed in the work 21. The spacer 26 is formed by cutting one iron plate each time so that one side thereof has a desired angle, and setting it as shown in FIG.

In such a conventional example, as described above, the spacer has to be made each time, and the accuracy of the long hole punched in the work is influenced by the accuracy of the spacer, which causes a problem of product variation. Furthermore, it is not easy to set the spacer, which requires time and effort. In the case of one kind of mass production, the trouble and time are compensated, but in the case of many kinds of small quantity production, there is a problem of increasing the cost of the product.

Therefore, the present invention can easily set up the work when punching an angled long hole in a work by a general-purpose press work, can ensure accuracy, and can be widely used for the same work. An object is to provide an angle abutment tool.

[Means for solving the problem]

The above-mentioned problem is to provide a screw near one end of a vertically long mounting bracket whose longitudinal side forms a reference surface, and mount a slide with an angle scale slidable in the left-right direction of the mounting bracket around the screw, When punching a long hole at an angle of θ to the reference plane on a workpiece by integrally connecting a right-angled ruler abutting part to one end of the slide (12) with angle scale through a connecting pin, use this scale. The angled slide is set to the angled slide, the slide with the scale is fixed with a screw, the workpiece is brought into contact with one side of the right-angled ruler abutting portion, and the long hole is punched out. Solve with this tool.

[Operation] That is, according to the present invention, a slide with an angle scale is slidably mounted on a mounting bracket fixed to a die base, and the mounting bracket is used as a reference surface. When the slide is set to a desired angle θ and fixed by the integration, the abutting part forms an angle of θ with respect to the mounting bracket, that is, the reference surface, so that one side of the abutting part abuts the abutting part. It becomes possible to punch a long hole with an angle of θ by a general-purpose press work.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

A preferred embodiment of the invention is shown in plan view in FIG.
In the figure, 11 is a mounting bracket, 12 is a slide with an angle scale (hereinafter,
Simply called a slide. ), 13 are right-angled ruler abutting parts (hereinafter,
It is simply called the hitting section. ), 14 is a connecting pin for connecting the abutment portion 13 to the slide 12 and integrating them, 15 is a screw for fixing the slide 12, 16 is a rotation center for the abutment portion 13 provided on the mounting bracket 11, 17 Indicates a work.

The fitting 11 is a fitting that extends long in the longitudinal direction, and one side in the longitudinal direction forms a reference plane when it is fixed to the mold base, and a screw 15 is provided near one end thereof. Mount the slide 12 so that it can slide in the left-right direction of the mounting bracket 11 around this screw, and screw it at the desired position.
The slide 12 can be fixed by tightening the screw 15. One end of the slide 12 is connected to the abutting portion 13 by a connecting pin 14, and the slide 12 and the abutting portion 13 are integrated. The abutting portion 13 is configured to be rotatable about a rotation center 16 provided at a substantially central portion of the mounting bracket 11.

The operation of the embodiment shown in FIG. 1 will be described. It is assumed that the workpiece 17 is punched with a long hole having an angle of θ with respect to the reference plane as shown in FIG. At this time, the slide 12 is slid so that the scale of the slide 12 is at the angle θ, and the screw 15 is tightened at this angle θ to fix the slide 12. At this time, one side of the abutting portion integrated with the slide 12 via the connecting pin 14 forms an angle θ with the side of the mounting bracket 11 in the longitudinal direction. Here, for example, when a rectangular work 17 is set at the position shown in the drawing to form an elongated hole, the elongated hole is formed at an angle θ with respect to the reference plane.

The abutment tool shown in FIG. 1 can be used in a large-scale production of one type or in a small-scale production of various types, and by using it, it is not necessary to use the spacer of the conventional example. The setup for the operation becomes extremely simple as described above, and the accuracy of the angle is ensured by the scale of the slide. The work 17 can be set at the position shown by the broken line in addition to the position shown by the solid line in FIG.

[Effect of device]

As described above, according to the present invention, the setup for forming the angled elongated hole in the work is simplified, the accuracy of the elongated hole is ensured again, and it can be widely used for the same work. The effect such as was obtained.
