Description

Transfer device of forming machine for cold forging using air cylinder {Forming machine using air cylinder}

The present invention relates to a transfer device of a cold forging forming machine using an air cylinder, and more specifically, to the transfer device of a cold forging high-speed forming machine is provided with an air cylinder driven by the control of the solenoid and the swing plate, A transfer device of a cold forging forming machine using an air cylinder in which the stopper of the air cylinder is reciprocated in front of the clamping part of the forming machine so that the clamping part of the forming machine can be stably held without dropping a product with a large taper degree. will be.

The transfer device of the cold forging forming machine is a device that automatically transfers the product from one forming process to the next forming process.

The forming process is a process of placing a material on a mold and applying a strong pressure to make a product of a desired shape. When the forming process is finished, the material is strongly pressed onto the mold. In order to transfer the material compressed in the mold to the next process, the material must be separated from the mold by pushing the material from the outside of the mold.

As described above, the tongs of the transfer device are picked up and fixed to the material that is separated from the mold mold and the transfer device transfers the material to the next process.

However, in the case of a conventional cold forging forming machine transfer device, when the product to be molded is a straight round product or a product having a small step difference and a small diameter difference between the upper and lower parts, the forceps of the transfer device are separated from the mold frame. There was no problem to fix, but if the taper is large or the diameter difference between upper and lower part is big, it is difficult to transfer the material to the next process because the clamp of the transfer device does not pick up the material properly There is this.

As described above, in the case of a product having a large degree of taper, a product having a long length, or a product having a large diameter difference between the upper part and the lower part, it is difficult for the forceps of the transfer device to pick up and transport the material. There is a problem that the machine cannot manufacture such a product.

The main object of the present invention for solving the above problems is to install an air cylinder controlled by a solenoid unit and a swing plate on the transfer device of the cold forging forming machine, the diameter of the product and the upper and lower taper large The present invention provides a transfer device for a cold forging forming machine using an air cylinder, characterized in that the product is supported by a stopper of the air cylinder so that the product does not fall off or tangle out of the tongs during the process of the product having a large difference.

As a means for achieving the above object, the configuration of the transfer device of the cold forging forming machine using the air cylinder according to the present invention is largely a stopper that reciprocates by the cylinder body and the air flowing in the cylinder body. An air cylinder made of; A swing plate for supplying air to the air cylinder; The air cylinder is characterized by consisting of a solenoid unit for controlling the operation direction of the air cylinder and the amount of air introduced so that the air cylinder can operate in the same way as the process timing of the forming machine.

Hereinafter, the configuration and operation of the transfer device of the cold forging forming machine using the air cylinder according to the present invention in detail with reference to the accompanying drawings so that those skilled in the art can be easily carried out in detail Let's do it.

First, Figure 1 is a circuit diagram of the transfer device of the cold forging forming machine using the air cylinder according to an embodiment of the present invention, the stopper (11, four stopper) is provided with four air cylinder (10); Two swing plate portions 20 for supplying air to the air cylinders; A solenoid unit 30 for controlling the operation of the air cylinder; It consists of an air hose 40 which is a passage of air connecting the above components.

In general, since the cold forging forming machine has five stages of pressure vessels, four air cylinders are required for transfer between each pressure vessel.

The transfer device of the cold forging forming machine using such an air cylinder is attached to the transfer device of the existing forming machine, and is operated when manufacturing a straight round product or a product having a small diameter difference between the upper part and the lower part. It is designed to be operated only when manufacturing a tapered product or a product having a large diameter difference between the upper part and the lower part.

The stopper 11, which is a piston rod portion of the air cylinder 10, is reciprocated in accordance with the operation timing of the tongs of the transfer device of the forming machine while the tapered product is not separated from the tongs. It serves to support.

In addition, the swing plate 20 always stores a predetermined amount of air in the air storage unit, and serves to supply air to the two air cylinders under the control of the solenoid unit. That is, when the stopper of the air cylinder needs to be operated quickly, a large amount of air is supplied, and when the stopper needs to be operated slowly, a small amount of air is supplied.

In addition, the solenoid unit 30 is composed of a solenoid valve 31 and an air pressure regulator 32 as a part for controlling the operation of the above components, the air cylinder in the air supplied to the forming machine from the air compressor ( 10) flows only as much air as necessary to operate, supplies the introduced air to the swing plate portion 20 through the air hose 40, and reciprocates the stopper of the air cylinder in accordance with the process timing of the forming machine. To control the movement.

The solenoid valve 31 is to change the flow direction of the air in accordance with the process timing of the forming machine to enable the air cylinder to operate in the same way as the process timing of the forming machine, different process timing for each product in advance When the product separated from the mold frame is picked up by the forceps part 50, the stopper 11 of the air cylinder is controlled to lower so as to prevent the product from being separated from the forceps part, and the transfer device moves as a whole to move the product to the next process. The stopper 11 of the air cylinder ascends at the moment of transfer to the air cylinder. Therefore, even if the manufacturing process time is different for each product, if the solenoid valve is set only in advance of the process time, the stopper of the air cylinder is correctly operated so that the product does not leave the tongs.

In addition, the air pressure regulator 32 serves to adjust the pressure of the air so that the stopper of the air cylinder is accurately operated at a set timing.

2 is a view showing a state in which the air cylinder stopper 11 supports the product A in the transfer device of the cold forging forming machine using the air cylinder according to an embodiment of the present invention. The cylinder 10 is installed on the front upper end of the forceps 50 of the transfer device of the forming machine to reciprocate.

Then, as shown in the drawing, the stopper 11 of the air cylinder 10 is lowered to catch the product A separated from the mold frame by the forceps 50 of the transfer device so that the product does not escape from the forceps. Support one end.

3 is a view showing a state in which the forceps unit 50 of the transfer device does not hold the product, and as shown, the forceps unit 50 is opened, and in this state, the stopper 11 of the air cylinder is air cylinder. Ascending to the inside of (10).

Herein, while the present invention has been described with reference to the preferred embodiments, those skilled in the art can make various modifications and applications without departing from the spirit and scope of the present invention as set forth in the claims below. This will be possible.

As described in the above embodiments, the present invention provides an air cylinder device additionally provided to the transfer device of the conventional cold forging forming machine, and has a large taper degree that is difficult to fix with the forceps of the transfer device of the conventional forming machine. It can be easily fixed and transported to products or products with a large diameter difference between the top and the bottom has the effect of improving the work efficiency.
