Abstract

PURPOSE:To perform practicable electromagnetic working over a wide range with simple constitution by conducting electric current from a storage device to a flat plate-shaped coil, and processing a work by making use of the electromagnetic repulsive force. CONSTITUTION:Electric current is conducted impulsively at a desired positional relation or desired timing from a storage device 9 to a flat plate-shaped coil 5 and a work 13 positioned below a coil holder 3 is processed by making use of the electromagnetic repulsive force. The holder 3 is equivalent to the slide of an ordinary press machine. Therefore when the slide position is in an upper part, a switch is turned on and a capacitor is charged. When the slide position descends and attains the prescribed distance from the work, the switch is turned on to actuate a switching mechanism, thereby an electric discharge switch is turned on.

This is a general press machine with a knockout device added. Considering that knockout is also a form of machining, it will be referred to here as knockout machining. When the workpiece 17-3 is fitted into the upper mold 33 after drawing has been completed, an impact current is applied from the power storage device 9 to the vP plate-shaped coil 5 of the coil holder 3, and the conductive plate The two are lowered to push the knockout bin 35 and push out the workpiece 13. The switching mechanism at this time can be a position detector using an optical sensor or a limit switch, as in the previous embodiment. These position detectors can be easily installed at any position, and this position can be changed freely by changing the position of the detector. The mechanical mechanism of the conventional knockout device pushes the knockout bottle downward just before it reaches the dead center, and it is difficult to operate it in a free position. Furthermore, mechanisms using hydraulic pressure or the like inevitably have a complicated structure. In the electromagnetic method of the present invention, the device is extremely simple, and it can be electrically automated easily at a desired height.Compared to drawing processing, the knocking process requires a small force, and therefore the power storage device The capacitor capacity is relatively small and p. In the figure, 37 indicates a buffer plate made of a material such as rubber.

The stroke is made larger. The figure shows the state before operation, and the flat coil 5 receives current from the power storage device 9 and is knocked out. The cylinder chamber 39 may be filled with an appropriate fluid. This is optimal when the drawing part of the workpiece 13 is deep, since it is possible to take a large knockout stroke.

FIG. 5 shows an electric potential machining device that utilizes the restoring force of a spring, and is shown in a partially cutaway front view. The processed parts are the same as those shown in FIG. 6, and the same reference numerals are the same, so please refer to FIG. 6, which is shown enlarged. A striker 45 is provided below the coil holder 3 via a restoring spring 47, and a striker 45 is provided below the coil holder 3 (in addition, a flat coil 5 and a striker 45 are provided below the coil holder 3).
The striker 45 is lowered by the electromagnetic repulsion force by placing two conductive plates provided in one part of the coil 5 facing each other and applying an impulsive current to the flat coil 5 in a desired positional relationship or at a desired timing. Due to its resilience, it is again 11
It was designed to cause harm. In this example, the striker 415 includes a punch 51 and is intended to fix the pierce nut 55 to the workpiece 13 that has been damaged on the die 53. In order to position a certain culm m, a coil holder is fixed to a slide of a press machine. When the position of the coil holder is detected and the switching mechanism is activated, the striker 45 to which the conductive plate 29 is attached is activated by the restoring spring/
Descend while compressing 17. The striker is provided with a section 450 at the bottom via a spring 57.
■-1 4 tensioners are strikers/159 parts 5
0 and presses down the workpiece 13. The extension 71.9 and the member 50 are engaged with the tip of a punch 51 of a S-Leica/1.5. When the striker 45 further descends, the spring 57 is compressed, and the punch 51 protrudes downward from the extension 49 to strike the workpiece 13.
Drilling of the hole, driving of the pierce nut, and caulking of the workpiece and the pierce nut 55 are instantaneously performed. After that, the punch 51 is moved to the striker 45 by the restoring tension force of the restoring spring 47.
At the same time, the upper arm extension 49 separates from the workpiece 13. The member 50 and the striker 45 are separated by the tension of the spring 57. After completing the work, return to the original state shown in FIG. Although an example of processing a pierced nut has been shown, it is clear that processing such as drilling, drawing, marking, caulking, etc. can be performed by preparing an appropriate mold. - A high degree of automation is possible because all processes are automatically completed with one discharge. As for the switching mechanism, it is also possible to use manual switching, detection of the position of the coil holder, or detection of the position of the workpiece.

In the electromagnetic processing apparatus shown in FIG. 5, the position of the coil holder can be appropriately positioned according to the product to be processed, but the difference is that the work is performed at a fixed position.

This electromagnetic machining device can perform the same machining as that shown in the embodiment shown in FIG. 5, such as drilling, drawing, caulking, marking ζ1, etc., and is particularly suitable for continuous mass production. For example, when continuously drilling holes in a long workpiece, the workpiece 13 is slid against the die 53 at a constant speed, while the switching mechanism is operated at regular intervals to repeat charging and discharging. For example, it is possible to drill holes at equal intervals.In the one-spring restoring type electromagnetic machining device shown in this example, it is not possible to detect the position of the coil holder and switch, so it is necessary to detect the position of the workpiece or use a timer, etc. Stitch together to make R8+.
