Abstract

PURPOSE:To hold a work surely and facilitate feeding in the bus bar material feeding device of a turret type punch press device, by clamping the work by a subclamp when the work becomes short. CONSTITUTION:A work 1 is fed by a carrying car 3 and worked by a turret table 4. When the work becmes short and comes off from the carrying car 3, a subclamp starts operation, and shifts a fitting stand 12 to the side of the work by the first air cylinder, and the side of the work comes into contact with the clamp car 21. Then, the second air cylinder 19 operates, and the fitting stand 23 passes under the work 1 and positions to opposite side of the work 1. Then, the third air cylinder 25 operates and a clamp car 27 goes up to the same height with the clamp car 21 provided on the upper face of a fitting stand 17. Further, the fitting stand 23 is pulled back slightly by operation of the second air cylinder, and the clamp car 27 is brought into contact with other side of the work 1, and the work 1 is clamped by two clamp cars 21, 27 and worked.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a material supply device, and more particularly to a busbar material supply device in a turret type punch press machine.

Conventionally, the equipment for this building was as shown in Figure 1. In Fig. 1, ■ is a workpiece to be processed, 2 is a support stand for transporting the workpiece in kilowatts, 3 is a transport vehicle installed in two rows at intervals on support 2, 4 is a turret table, and 5 is a A cutting die provided on the turret table 4, 6 a rotating machine for rotating the turret table 4, 7 a drilling die provided on the turret table 4, and 8 a ram.

To explain the operation of the conventional busbar material supply device for this turret type punch press device, a workpiece 1 is placed between two rows of transport vehicles 3 and sent to a turret table 4. At the same time that a predetermined length of the tip of the workpiece 1 is positioned on the turret table 4, the turret table 4 is simultaneously driven by the rotary machine 6, and the punching die 7 thereon is positioned directly below the tip of the workpiece 1. Next, the ram 8 descends to apply pressure, thereby drilling a predetermined length of the tip of the workpiece 1. At this time, the transport vehicle 3 also plays the role of clamping the work l.

By the way, when the workpiece 1 is repeatedly subjected to drilling, cutting, and machining, and then the workpiece 1 is fed again by a predetermined length, the workpiece 1 will eventually be conveyed. 8 At this point, it will be so short that it won't hang over the car 3.
The operator either manually transports the workpiece and processes the short workpiece 1, or simply transports the workpiece and finishes machining the base material when the workpiece no longer hangs.

In this way, with the conventional carrier-type material supply device, as mentioned above, from the point where the workpiece is no longer placed on the carrier, the subsequent processing feeds are made of wax and are processed in an unstable state. It had drawbacks such as being difficult to remove.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to eliminate the drawbacks of the conventional material, to provide a material feeding device that reliably holds a shortened workpiece, allows easy feeding, and enables effective removal of debris. .

Below, the format supplying device of the present invention'fr: Preferred actual IM shown in the drawing with Vti? We will examine J and explain it in more detail.

2 to 4 show a material supply device according to an embodiment of the invention together with a turret type punch press device. In FIGS. 2 to 4 showing this embodiment, parts that are the same as or correspond to the conventional material supply device and turret punch press shown in FIG. 1 are designated by the same reference numerals. The explanation will be omitted.

The material supply device of the embodiment is attached to the support stand 2,
It has transport vehicles 3 arranged in two rows facing the turret table 4 of the punch press device. The material supply device further includes a pedestal 10 attached to the turret table 4 side of the support base 2 and disposed along the periphery of the table 4. A sub-clamp 11 is installed on the pedestal 10 to support the tip of the workpiece 1 sent by the carrier 3 of the support base 2 on the female turret table 4 in the same way as the carrier 3. Details of this sub-clamp 11 are shown in Figures 3 and 4.
As shown in the figure.

This sub-clamp 11 is equipped with a mounting base 12 for installing it on a mount 10, and a bracket 13 formed on this mounting base 12 has a first air cylinder 14 that connects its piston rod 15 to the workpiece 1. It is installed so that it extends in the direction across the hyperactive path. An electric value valve 16 is attached to the end of the first air cylinder 14 for releasing the power to the Mr. i' air cylinder 14.

Another mounting base 17 can be fixed to the end of the piston rod 15 of the first air cylinder 14, and the second air cylinder 19 is attached to the piston rod 2o on the bracket 11 of the base 17. The first air cylinder 14 is attached to extend in the same direction as that of the first air cylinder 14, and a clamp wheel 21 is rotatably attached to the upper surface of the base 17. A solenoid valve 22 for controlling the release of air to the cylinder 19 is also installed at the end of the piston rod 20 of the second air cylinder 19. is fixed, and this U mount 23
A third air cylinder 25 is installed on the upper bracket 24 of the air conditioner so that its piston rod 26 extends upward. A solenoid valve 2q is also attached to the end of the third air cylinder 25 to release air from the cylinder 25, and a clamp wheel 27 is attached to the end of the piston rod 26 of $i and 2 (-). installed as possible.

The reference numeral 28 is attached to the side of the stand 170 when the first air cylinder 14 (7) is operated to stabilize the movement when the stand 17 moves, and the other end is attached to the side of the stand 12. A guide cassette inserted through a hole formed in the bracket 13 is shown.

In the material supply device configured in this way, the support stand 2
The workpiece 1 moved by the transport vehicle 3 is moved forward or backward by a claw guide 9 held at its rear end. This process of inserting or bending the workpiece 1 on the knot diameter 4 and cutting it after the joint is repeated in sequence and becomes shorter, and when the workpiece 1 no longer hangs over the transport vehicle 3. , the sub-clamp 11 operates.

That is, as mentioned above, when the workpiece 1 becomes short, the turret table 4 is first rotated by the rotary machine 6, and the required drilling die 7 is positioned under the workpiece cutting circle.

Next, the first air cylinder 14 of the sub-clamp 11
is activated, the mounting table 17 is completely transferred to the side of the work, and the first air cylinder 14 is stopped at the position where the side of the work and the clamp base 21 come into contact. Then, the second air cylinder 19 is operated, and the mounting table 23 is transferred passing under the work 1 and positioned on the opposite side of the work 1.

Next, the third air cylinder 25 is activated, and the clamp base 27 is attached to the clamp base 21 installed on the upper surface of the base 17.
Raise it until it is at the same height.

After sowing, the mounting base 23 is slightly pulled back by reactivation of the second air cylinder 19, and as a result, the clamp base 27 is set at a position where it abuts the other side of the workpiece 1.

Then, the workpiece 1 is
is clamped, and during this time the workpiece is subjected to J9r processing. When the turret table 4 rotates again, the sub clamp IIFi is retracted, the work 1 is sent after positioning the turret table 4, and the sub clamp 11 enters to fix the work 1 when drilling or cutting is performed.

Further, the return operation of the sub-clamp 11 is performed in the reverse order to the above-described order.

In the embodiment described above, the sack lamp 11 was retracted when the turret table 4 was rotated, but the turret table 4 may be rotated by retracting both the support base 2 and the mount 10 with the sub-clamp 11 kept in place.

As explained above, by adding a sub-clamp to the tip of the material supply device in equipment that uses a turret-type punch press to perform processing such as drilling, bending, and cutting, it is possible to effectively take out material and shorten the body. Parts can be processed and sent easily and inexpensively. Moreover, according to the above-mentioned sub-clamp, even if the width of the workpiece changes, it can be reliably clamped.
