Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a template chile for a punching machine such as a punching machine or a nibbling machine.

More specifically, the present invention relates to a movable template table in a punching device that punches the same pattern by following a template with a stylus attached to a moving device that moves a workpiece.

Generally, when copying is performed in a punching machine, a template table is provided on which a rectangular template is mounted.

In punching machines that copy small workpieces, the template table and the work table on which the workpiece is placed are the same, but in punching machines that copy and machine large workpieces, the template table is the same as the work table on which the workpiece is placed. The template table is separately provided with a work table and a movable template table.

The reason why the template table is movable is to move the template table to a position that does not interfere with the work of the operator when performing gauging processing that does not use a template, and also to allow the template table to be moved to a position that does not interfere with the work of the operator. This is to enable copying by moving the coordinates of the template when punching large workpieces repeatedly.

Conventionally, a rectangular template is mounted on a movable template table in a crawling manner.

First, place a reference hole on the template at a position that does not interfere with the tracing hole (for example, x = a for the coordinates where the reference corner of the rectangular template is the reference point X1-0.yl-0).
ty1=b).

However, this reference hole cannot always be provided at a fixed position on the template 1, and its position changes depending on the machining pattern, etc.

Next, using the carriage bar of the moving device that moves in the X-axis and Y-axis directions, the reference corner of the rectangular workpiece is set at the origin (x□= o, yo=o), the template is moved by a distance (Xo-a, yo-b) corresponding to the reference hole of the template and fixed.

A rectangular template is placed on a template table that is movable in the Y-axis direction, and a stylus attached to a carriage bar is inserted into a reference hole in the template to position and fix the template on the template table.

Thereafter, the template table is fixed to restrict movement in the Y-axis direction.

However, with a template that is not fixed on the template table, the coordinate axes of the template and carriage bar are not parallel due to play in the mounting holes drilled in the template. The parallelism of the template had to be adjusted by sliding it on the side, which required a great deal of effort on the part of the operator.

The present invention was devised in view of the above-mentioned problems, and one embodiment of this invention will be described in detail below with reference to the drawings.

1, the copying process is completed by repeating the punching process on the workpiece 3.

Note that when the workpiece 3 is larger than the template 19, the stylus 11 is first engaged with the positioning bush 85 attached to the template table 23, so that the template table 23 and the carriage bar 57 etc. are integrated. to hold.

Next, the fixation of the template table 23 is released, and the carriage bar 57, template table 23, etc. are moved in the Y-axis direction by the required coordinate movement distance of the template 19.

Thereafter, by fixing the template table 23 and releasing the engagement between the positioning bush 85 and the stylus 17, the template table 23 has been moved by the required distance in the Y-axis direction.

Thereafter, the stylus 17 is repeatedly engaged with the profiling hole of the template 19 to perform the profiling process.

Note that the coordinate movement in the X-axis direction can be performed by moving the stylus 17 in the X-axis direction with respect to the carriage bar 57.

As can be understood from the above description of the embodiments, the gist of this invention is as stated in the claims of the utility model registration. The relative positional relationship between the device and the template chief can be accurately determined.

Therefore, when the workpiece moving device is positioned at the reference position, the reference position of the template tiple is set by engaging the stylus with the positioning bushing.

After the template table is set at the reference position in this way, the template is positioned by bringing the reference side surface of the template into contact with the lineup pin, thereby setting the template at the reference position.

Therefore, there is no need to provide a reference hole in the template as in the prior art, and the problems of the prior art described above can be solved.

For example, if the workpiece is a rectangular plate and one or more sides are required to have a curved outline, the sides of the template can be made to have a curved outline. A continuous punching process (generally referred to as nibbling process) may be performed following the section.

If the sides of the template are curved and irregular, and the template is relatively large, the line-up pins can be recessed into the bottom of the template so that the template can be fixed without any problems. can be used to create a template template.

When copying a large workpiece using a small template and repeating the same pattern in the X-axis direction, for example, move the stylus attached to the carriage bar by the length of the template in the X-axis direction. This would be possible.
