Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a press machine.

[0002]

2. Description of the Related Art In recent years, press parts have become smaller, more complex and more accurate with the trend of lighter, thinner, shorter and smaller products.
On the other hand, in the assembly process, assembly by an automatic machine has become the mainstream for labor saving and unmanned operation. In such a flow, it is becoming important to align and take out the parts lowered by the press machine and to incorporate them in the product without impairing the quality.

A conventional method of transporting a pressed part to an assembly machine will be described below with reference to FIGS. In FIG. 6, 21 is a press device, 22 is a press die, 24 is a conveyer for carrying out the parts 23 processed by the press die 22, 25 is a stacker for storing the parts 23, 26 is a parts feeder, 27 is an assembly robot, 28 is a product in which the component 23 is incorporated.

Next, the operation of the processing and assembling line having the above construction will be described. First, the parts 23 punched by the press die 22 in the pressing device 21 are carried out of the pressing device 21 by using the conveyor 24 and accumulated in the stacker 25. Next, transport the stacker 25 to the assembly process,
The parts 23 are aligned by the parts feeder 26, received by the assembly robot 27, and incorporated in the product 28.

FIGS. 7 to 9 are views showing a working process by the press die 22 in the press device 21. 7 to 9, 31 is an upper ram, 32 is an upper die set, 33
Is a punch, 34 is a punch plate, 35 is a stripper, 36 is a stripper spring, 37 is a die plate, 38 is a lower ram, and 39 is a material.

First, as shown in FIG. 7, the material 39 processed until one step before the final step is sent. Next, FIG.
After the stripper 35 presses the material 39, the punch 33 descends to pull out the component 23, as shown in FIG. After that, the punch 33 rises and the removed parts 23 are carried to the outside of the mold 22 by the conveyor 24, dropped on the stacker 25, and accumulated.

FIG. 10 shows a method of transporting the component 23 in another conventional example. In FIG. 10, reference numeral 41 is a positioning device for positioning the component 23 carried out of the mold 22 by the conveyor 24, 42 is a hoop carrier, and 43 is a hoop carrier.
From the positioning device 41 to the hoop carrier 42
It is a transfer robot to be inserted into.

Explaining the operation of the line having the above construction, first, the component 23 carried out of the mold 22 by the conveyor 24 is positioned by the positioning device 41, then taken out by the transfer robot 43, It is inserted into the fitting portion of the component 23 formed on the hoop carrier 42, and is sequentially sealed with a top tape. Next, the hoop carrier 42 is carried to the assembly process, where the assembly robot takes out the component 23 from the hoop carrier 42 and incorporates it into the product.

[0009]

However, in the conventional method for transporting the stacker 25, the stacker 2 is used.
There is a problem that the component 23 may be scratched, deformed, or dust may be mixed in during the transportation of No. 5. In addition, there are problems that scratches may occur due to the collision of the components 23 in the parts feeder 26 and that it is difficult to align the components 23 having a complicated shape. Further, in the conventional example using the transfer robot 43, there is no mixing of dust or scratches, but there is a limit to the speed at which the transfer robot 43 inserts the component 23 into the hoop carrier 42, and the original production of press processing is limited. There was a problem that speed could not be exhibited.

In view of the above problems of the prior art, it is an object of the present invention to provide a press device capable of accurately and stably inserting a press part having a complicated shape into a hoop carrier at high speed.

[0011]

The pressing device of the present invention comprises:
In a press device for punching the material supplied onto the die plate with a punch to process the press component, the punch is provided with means for preventing the press component from falling, and the hoop carrier of the hoop carrier is provided below the die plate so as to pass directly below the punch. It is characterized in that a punching stroke is set such that a passage is provided and a press part punched by a punch is held and inserted into a fitting part of the press part formed on the hoop carrier.

[0012]

According to the present invention, the parts are held by the punch even after punched by the punch and moved to the bottom dead center, and the parts are fitted to the fitting portion of the hoop carrier waiting at the bottom dead center. Is inserted. After insertion, the part remains in the hoop carrier and only the punch rises. Thus, the parts can be inserted and removed directly from the mold into the hoop carrier.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A press apparatus according to an embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 conceptually shows the structure of the main part. In FIG. 1, 1 is a punch, and a suction hole 8 is formed in the center of the punch up to the tip.
Is provided so that air can be sucked in to suck and hold the punched parts. A hoop carrier 2 is provided with a fitting portion 9 so that the parts do not move during transportation. 3 is a pressed part. Reference numeral 4 denotes a die plate, and a passage 5 for the hoop carrier 2 is formed below the die plate so as to pass through the position directly below the punch 1. 6
Is a top tape, which is affixed to the upper surface of the hoop carrier 2 so that the inserted component 3 does not drop and dust is not mixed in during transportation. 7 is a material of the component 3.

Next, the specific structure of the press machine will be described with reference to FIG. In FIG. 2, 11 is an upper ram, 12 is an upper die set, 13 is an air tube, one end of which is connected to the suction hole 8 of the punch 1 and the other end of which is connected to a suction device (not shown). Reference numeral 14 is a punch plate for mounting and fixing the punch 1. Reference numeral 15 is a stripper, 16 is a stripper spring, 17 is a lower ram, and 18 is a hoop carrier feeding device.

The operation of the press device configured as described above will be described with reference to FIGS.

First, as shown in FIG. 2, the material 7 which has been processed up to one step before the final step is sent. next,
After the stripper 15 holds down the material 7 as shown in FIG. 3, the punch 1 descends and the component 3 is pulled out. At this time, air is sucked through the suction holes 8 of the punch 1 from its tip, so that the removed component 3 is suction-held by the tip of the punch 1 and further descends together with the punch 1. As a result, the component 3 is inserted into the fitting portion 9 of the hoop carrier 2 when the punch 1 moves to the bottom dead center as shown in FIG. At this point, the air suction from the suction holes 8 of the punch 1 is stopped, and the air suction is stopped until the punch 1 reaches the top dead center. Thereafter, as shown in FIG. 5, the component 3 is transferred to the hoop carrier 2, the punch 1 is lifted, and the hoop carrier 2 is fed by the hoop carrier feeding device 18 by one pitch.

As described above, according to this embodiment, the punch 1
Since the suction hole 8 for the component 3 is provided in the component 3, the punched component 3 can be held as it is and inserted into the hoop carrier 2. Moreover, since a parts feeder and a robot that inserts parts into the hoop carrier, which are conventionally required, are not required, the cost of equipment can be significantly reduced.

Although air is used to prevent the parts from falling in this embodiment, it goes without saying that a magnetic method using a mechanical cam mechanism or an electromagnet may be used.

[0020]

As described above, according to the present invention, since the punch is provided with the component drop preventing means and the punched component is directly inserted into the fitting portion of the hoop carrier, it is highly accurate and complicated. Even shaped parts can be supplied to the assembly machine in an aligned state without deterioration in quality with the hoop carrier, and parts in the state of being inserted into the hoop carrier can be obtained with almost no decrease in production speed. .
