Description

[Detailed description of the invention] The present invention is a plate for a single type press, which is constructed by combining a main plate made of metal or synthetic resin with an edge plate, or a plate for a double type press made of metal or synthetic resin. This relates to the slide show of the overboard.

Conventionally known over-plates made of one-piece structure made by casting, or over-plates manufactured from thick plates by machine cutting, are thick enough, so a notch corresponding to the thickness of the main body is provided. However, in recent years, in order to reduce costs and reduce the weight of the overboard, the overboard has been made thinner and multiple spacers have been installed to reduce the differential pressure between the rooms. There is a tendency to create structures that prevent bending and deformation due to In such cases, when the overboard moves on the rails on the sidebar, a shoe is provided in the handle part to stabilize the movement. As shown in FIGS. 1, 2, and 3, the slide show portion of the handle of such a conventional overplate is attached to a slide fitting manufactured separately from the main plate by welding or bolting.

FIG. 1A shows a front view of a single overplate, and FIG. 1B shows a partial plan view of the single overplate. In the figure, 1 is a main plate, 2 is an edge plate, 3 is a handle portion, and 4 is a slide shoe. FIG. 2 shows a case where a slide shoe 4 is welded to the handle portion 3 of the overplate. In the figure, 5 indicates a rail, 6 indicates a side bar, and 7 indicates a welded portion. FIG. 3 shows a case where the slide shoe 4 is fastened with bolts 8 to the handle portion 3 of the overplate.

However, with those attached by welding, it is difficult to make the angle of the slide surface to the main plate exactly perpendicular due to distortions caused by welding.
In addition, the contact surface between the slide show and the rail becomes unstable due to the left and right sides not being parallel, which may cause vibrations (vibration when moving the overboard) when the finished product is moved. Additionally, if the slide shows are welded before attaching the edge plate, the slide shows will come into contact with each other during storage, making it impossible to stack them, and when stored flat, the main plate may deform or the slide show may bend. be.

Furthermore, those made by welding have the drawback of the perpendicularity of the mounting angle between the handle and the slide shoe, and the number of welding operations required is large, making it very expensive.

On the other hand, when mounting with bolts, the slide shoe can be made of a cast or forged product and there is no mounting distortion, but the price is high.

In addition, in the case of a single overboard, if the edge plate is attached, the slide shoes will not touch each other even if the overboard is stacked, so there is no problem during transportation (such as stacking or contact of the slides when stacking). do not have.

In the case of multiple overplates, the handling is done with overplates,
Since the frames are manufactured in separate processes and in different locations, if the slide show is attached to the main plate,
Slideshow comrades come into contact with each other, which poses a huge problem in terms of process control.

Also, the slide show is attached by welding.
When the frame opening machine malfunctions and pulls one side against the overboard, the slide show may become deformed or break and fall off, but in such cases, replacing only the slide show is done by tightening the bolts. There are also drawbacks, such as the fact that it is impossible to do so, as in the case of

The present invention was developed in view of the above-mentioned drawbacks, and its gist is that a groove that engages with the notch or an insertion hole for the protrusion is formed on the slide surface in a notch or protrusion provided at the bottom of the handle of the overplate. This invention relates to an overboard having a slide show, characterized in that a slide show provided on the opposite side of the plate is detachably attached.

The present invention will be explained in more detail with reference to the drawings. FIG. 4 shows a notch 10 provided in the handle 3 on the main plate 1 side of the overplate, and a slide shoe 11 that engages with this notch 10. Slide show 1
The lower surface of 1 has a slide portion 12 that straddles the rail, and the opposite surface has a groove 1 that engages with a notch 10.
3 is provided. Slide show 11 is the 5th
As shown in the figure, the notch 10 and groove 1 of the handle 3
3, it is reliably held in the handle portion 3 in a detachable manner.

FIG. 6 also shows a slide show 11 having a protrusion 14 provided on the handle 3 on the main plate 1 side of the overplate and a fitting hole 15 into which the protrusion 14 is inserted. The lower surface of the slide shoe 11 has a slide portion 12 that straddles the rail, and the opposite surface thereof is provided with a fitting hole 15 into which a protrusion 14 is fitted. As shown in FIG. 7, the slide shoe 11 is detachably held by inserting the protrusion of the handle of the overplate into the insertion hole.

It is preferable that the slide show is manufactured by casting, forging, injection molding, etc., and the cutout grooves and insertion holes are used without expensive mechanical processing.

As explained above, according to the present invention, it can be installed without welding, so there is no need to consider distortion.

Since the main plate and the slide shoe are not restrained by welding or bolting, the shoe and rail are in close contact with each other in a natural shape, and there is no vibration between the slide shoe and the rail when the plate is moved over.

Cost is low.

The slide show does not get in the way when moving overboard during production and transportation, so workability and storage are good.

It has the following advantages and has great practical effects in industry.
