Description

[Detailed description of the invention] This invention relates to a machine that corrects and cuts the bed surface of a press.

Conventionally, when attaching a modification machine to a press for modifying the press bed surface, the modification machine is placed on the floor, one end of the bar is welded to a part of the press, and the other end is welded to the modification machine. A correction machine was attached to the press.

However, with this installation method, when cutting the press bed surface that is parallel to the bottom surface of the ram of the press, in order to obtain parallelism between the bottom surface of the ram and the bed surface, the distance between the bottom surface of the ram and the bed surface is adjusted at various points using a rod micro etc. Since it is necessary to carry out the installation work while making measurements over a period of time, the number of man-hours required for installing the correction machine to the lower surface of the press ram increases, which is uneconomical.

This invention provides a press bed surface modification machine that is easy to install on the bottom surface of the press ram, can set the distance from the bottom surface of the press ram to a desired value, and can be installed at a desired angle of inclination to the bottom surface of the press ram. purpose.

This invention will be explained below with reference to drawings showing embodiments.

FIG. 1 shows an embodiment of this invention. In the figure, 1 indicates a press, and 2 and 3 indicate the ram and bed of the press 1, respectively.

4 shows a bow pull type correction processing machine.

This modification processing machine 4 includes a guide member 5 extending with a constant thickness, a carriage 6 slidably attached to the guide member 5, and a guide member 5 attached to the carriage 6. a cutter mounting base 8 that can swing around a right-angled mounting axis I;
It consists of a milling cutter 9 rotatably attached to a mounting base 8.

The axis of the milling cutter 9 is parallel to the mounting axis 7.

The guide member 5 of the modification machine 4 is attached to the r surface 2a of the ram 2 of the press 1 with bolts 10.

In accordance with the above configuration, the lower surface 2a of the ram 2 and the bed surface 3a of the bed 3 are parallel, and therefore the guide member 5 is parallel to the bed surface 3a of the bed 3.

Therefore, the carriage 6 can move parallel to the bed surface 3a, and the milling cutter 9 can perform two-dimensional movement within a plane parallel to the bed surface 3a.

Therefore, the ram 2 is lowered and the milling cutter 9 is moved to the bed 3.
When the milling cutter 9 is brought into contact with the bed surface 3a of the ram 20 and moved two-dimensionally while rotating, the bed surface 3a can be corrected and cut in parallel to the lower surface 2a of the ram 20.

FIGS. 2 and 3 show a mounting jig that is inserted between the guide member 5 of the modification machine 4 and the ram 2 when the milling cutter 9 is used to modify the bed surface that is inclined with respect to the lower surface 2a of the ram 2. The tool 11 is shown.

The mounting jig 11 is the upper surface 5a of the guide member 5 of the correction processing machine 4.
a lower mounting plate 13 attached by bolts 12 to the lower mounting plate 13;
An upper mounting plate 16 that is attached to the lower surface 2a of the ram 2 via an angled mounting piece 14 and bolts 15, and a connecting mechanism 17 that holds the lower mounting plate 13 parallel or inclined to the upper mounting plate 16. It has become.

The connection mechanism 17 has four parts arranged in a rectangular shape on the lower mounting plate 13.
The lower metal fittings 18, the upper metal fittings 19 formed in the same rectangle as the rectangle formed by the lower metal fittings 1B and attached to the upper mounting plate 16, and the corresponding upper and lower metal fittings 19 and 18 are pivotally connected by pins 20. 4 lines (only 2 lines are shown in Figure 2)
A turnbuckle 21 and a pair of upper and lower metal fittings 19 and 18 diagonally opposite each other have both ends pivoted to pins 20.
It consists of a diagonal member 22 of a book (only one is shown in FIG. 2).

In the above configuration, the upper mounting plate 16 is attached to the lower surface 2a of the ram 2.
To attach the upper mounting plate 16 to the lower surface 2a of the ram 2, attach the four corners of the upper mounting plate 16 to the mounting pieces 14, respectively.
The mounting piece 14 is tightened to the ram 2 with the bolt 15 while supporting it with the ram 2.

Next, the guide member 5 of the correction processing machine 4 is attached to the lower surface of the lower attachment plate 13 by the port 12.

In this state, the four turnbuckles 21 are adjusted to tilt the lower mounting plate 13 upwardly to the right or downwardly to the right with respect to the upper mounting plate 16.

- That is, the guide member 5 of the modification machine 4 is inclined with respect to the upper surface 3a of the bed 3 of the press 1.

In this state, when the ram 2 is lowered to bring the milling cutter 9 into contact with the upper surface 3a of the bed 3, and then the milling cutter 9 is rotated, cutting at an angle with respect to the upper surface 3a of the bed 3 can be performed.

The press bed surface modification machine of this invention has a guide member that can be attached to the underside of the press ram and is parallel to the ram surface.
It consists of a carriage that is slidably attached to this guide member, and a milling cutter that is attached to the carriage so that it can swing in a plane parallel to the guide member, so that the ram of the press of the correction machine is The installation work is extremely simple, and when the modification machine is attached to the press ram, the moving surface of the milling cutter can be held parallel to the press bed surface, so the cutting work efficiency of the press bed surface is significantly improved. improves.

Further, by attaching this modification machine to the ram via a mounting jig having a mounting plate that can be adjusted to be inclined with respect to the lower surface of the ram of the press, it is also possible to process an inclined cutting surface on the bed surface of the press.
