Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a slide plate of a movable body in a workpiece processing machine.

<Prior art> For example, when cutting (or hemming is also possible) the edge of a press-formed metal plate, the first processing machine
As shown in the figure, a holding stand 2 for a workpiece W is fixedly installed on a fixed base 1, and the workpiece W placed on this holding stand 2 is held down by a pressing member 3 that moves up and down, and is horizontally placed on the fixed base 1. A cutting blade 5 is attached to a moving body 4 that moves forward and backward.
The movable body 4 is moved forward by the downward movement of the cam 9 that moves up and down, and the edge of the workpiece is cut by the cutting blade 5, and the movable body 4 is moved backward by the return spring 8 as the cam 9 rises. be. In this case, in order to maintain cutting accuracy, a slide plate 6 is fixed to the lower surface of the movable body 4, and a fixed slide plate 7 is provided on the fixed base 1 in surface contact with the slide plate 6. If the slide plates 6 and 7 wear out, burrs will form on the cut portion of the workpiece W, reducing quality. Therefore, the slide plates 6 and 7 are periodically removed and measured with a micro gauge to check the wear condition. Ta. Therefore, the time required for measurement is long, and during that time, machining must be interrupted for a long time, which has an adverse effect on productivity, and there are problems in that troublesome measurement work using a microgauge is required.

<Purpose of the invention> The purpose of the invention is to provide a slide plate that makes it possible to visually determine abnormal conditions without measuring the wear condition with a microgauge, and that eliminates the above-mentioned conventional problems. .

<Structure of the invention> The characteristic structure of the invention is that, in a slide plate that slides a movable object on a fixed surface by surface contact, a concave groove of a predetermined size and depth is provided on the sliding surface of the slide plate to determine the amount of wear. was formed.

<Embodiments> Examples of the present invention will be described below with reference to FIGS. 2 to 4.

In FIG. 2, 6 and 7 are slide plates of the movable body 4 in the processing machine shown in FIG. 1, for example, and the slide plate 6 will be explained below as a representative.

In the present invention, the sliding surface 1 of the slide plate 6
1 has a groove of a predetermined depth and a predetermined size for determining the amount of wear. This concave groove may be a single groove with a depth that is the limit dimension for the amount of wear, or one or several grooves may be provided in a cross shape.

Furthermore, as shown in FIG. 3, a plurality of grooves 10a, 10b, 10c having different depths may be used. In this case, for example, the deepest groove 10c is set to 8/100 mm, which is the limit of the amount of wear, the groove 10b is set to 5/100 mm, and the groove 10a is set to 2/100 mm.

Therefore, in the present invention, the grooves 10a to 1
The amount of wear can be immediately determined simply by visually observing 0c. For example, in the slide plate 6 having grooves 10a to 10c shown in FIG.
As shown in the figure, if the concave groove 10a has disappeared due to wear, the amount of wear is 2/100 mm when the groove depth is set as described above, and the amount of wear exceeds the limit by 8/1.
00mm, it is quickly confirmed that it can still be used.

<Effects of the invention> As described above, in this invention, since the amount of wear is determined based on the condition of the groove of a predetermined depth that indicates the amount of wear provided on the sliding surface, it is possible to easily remove the slide plate in an extremely short time. In addition to being able to check the wear condition of the moving body, the grooves also reduce sliding friction, and the grooves serve as oil reservoirs for lubricating oil, which is particularly effective in ensuring smooth sliding motion of moving objects. have.
