  However, in the above-described conventional method of supplying a blank from a former former to a rolling machine, when the blank is pushed out from the final stage die and dropped onto a conveyance means such as a shooter or a conveyance belt, a dent is caused by a drop impact, There is a risk that the quality may deteriorate, and it is necessary to send the blanks that have fallen on the transport means to the rolling machine while aligning the directions, so the supply mechanism and supply path become very complicated, In addition, there is a problem that the supply cannot be performed quickly and smoothly.

  Accordingly, the present invention eliminates the occurrence of the above-mentioned dents, and a simple and easy supply mechanism of blanks from the former to the rolling machine, and also can ensure that the direction of the blanks are aligned and can be supplied quickly and smoothly. An object of the present invention is to provide a blank supply device from a machine to a rolling machine.

  In order to solve the above-described problem, a device according to claim 1 of the present application is a blank feeding device from a former to a rolling machine that forms a material from coarse to fine by a plurality of forging stations, and includes a die in a final process of the former. In this hole, a blank supply passage that allows insertion of a blank formed into a predetermined shape in the previous process and extends to the feed port portion of the rolling machine provided at the rear position of the final process is disposed, while a high pressure is applied to the punch in the final process. A high-pressure air discharge passage is provided for supplying a blank by air directly to the rolling machine via the blank supply passage, and a high-pressure air supply device is provided that communicates with the discharge passage and feeds the high-pressure air into the discharge passage. It is characterized by that.

  In addition, the device according to claim 2 of the present application starts discharging high-pressure air to the high-pressure air supply device according to claim 1 at the timing when the forward movement into the hole of the blank die by the punch in the final process is finished. A discharge control mechanism for stopping high-pressure air discharge at the timing when the punch moves backward from the die is provided.

  According to the blank supply device from the former of the present invention to the rolling machine, the blank formed into the predetermined shape by the above-described configuration is supplied to the blank of the final process by the high pressure air discharged from the punch of the final process. It can be directly supplied to the rolling machine with a uniform direction through the passage. This eliminates the occurrence of dents as in the prior art, simplifies the mechanism for supplying blanks from the former to the rolling machine, and ensures that the direction is aligned and can be supplied quickly and smoothly.

  In addition, high-pressure air supply begins to discharge high-pressure air at the timing when the forward movement of the blank die into the hole of the die is finished, and stops high-pressure air discharge when the punch moves backward from the die. Since the discharge control mechanism is provided, the blank die can be pushed into the hole of the die by the punch in the final process as usual, and the discharge of the high-pressure air is stopped when the punch moves backward from the die. Therefore, the high-pressure air does not blow around the front surface of the die and does not adversely affect the blank transfer by the material transfer chuck.

  Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show a blank supply device from a former to a rolling machine according to the present invention. The former 1 is provided with a die block 3 at a predetermined position of a machine base 2, and a plurality of dies ( (Only the last die is shown in the figure) 4 is equipped. As is well known in the former 1, the ram 5 is positioned at the front surface of the die block 3 corresponding to each die 4 and the same number of punches (corresponding to each die 4 in the ram 5) By providing 6 (only the final punch is shown), each die 4 and punch 6 form a plurality of forging stations.
Then, as the ram 5 advances, rod-shaped cutting materials are sequentially forged at each forging station, and are configured to be an axial blank A with both ends having a small diameter and an intermediate portion having a large diameter as shown in the figure. Yes. Although not shown, a material transfer chuck (only the final chuck is shown in the figure) 7 for transferring a cutting material between adjacent forging stations is provided on the die block 3 side. The rolling machine 8 includes a fixed flat die 8a and a moving flat die 8b, and forms a plurality of annular grooves a ... a on the outer periphery of the large-diameter portion of the shaft-shaped blank A formed by the former 1. It is disposed at a position behind the die 4 in the final process of the former 1.

  As shown in FIG. 1, a blank supply device 10 that supplies blank A from the former 1 to the rolling machine 8 is provided in the final process of the former 1. As the blank supply device 10, supply of the rolling machine 8 that allows the insertion of the shaft-shaped blank A formed in the previous process into the hole 4a of the die 4 in the final process of the former 1 and is provided at the rear position of the final process. While providing a blank supply passage 11 made of a pipe pipe extending to the port 80 portion, high pressure air for supplying the blank A to the punch 6 in the final process by high pressure air to the rolling machine 8 through the blank supply passage 11. A discharge passage 12 is provided, and a high-pressure air supply device 13 such as a compressor that communicates with the discharge passage 12 and feeds high-pressure air into the discharge passage 12 is provided.

  The high-pressure air supply 13 starts discharging high-pressure air at the timing when the forward movement of the blank A into the hole 4 a of the die 4 by the punch 6 in the final process is finished, and the punch 6 moves backward from the die 4. A discharge control mechanism 14 that stops the discharge of high-pressure air at a timing is provided. The discharge control mechanism 14 controls the high-pressure air supply unit 13 based on a detection signal from a sensor 15 that detects the end of forward movement of the ram 5, and starts discharging high-pressure air at the timing when the forward movement ends. The high pressure air supply unit 13 is controlled so as to stop the discharge of the high pressure air at the timing when the punch 6 starts to retract from the die 4.

  Next, the operation of the above-described blank supply device will be described.

  First, in each forging station of the former 1, rod-shaped cutting materials are sequentially forged, and a shaft-shaped blank A having a small diameter at both ends and a large diameter at the middle portion is used as a final die 4 as shown in FIG. The material is transferred forward by the material transfer chuck 7. Next, the punch 6 advances and pushes the blank A into the die 4 as shown in FIG. Then, at the timing when the forward movement of the punch 6 is finished, discharge of the high pressure air from the discharge passage 12 of the punch 6 by the high pressure air supply machine 13 is started. Thereby, the blank A is directly supplied to the rolling machine 8 via the blank supply passage 11 provided in the die 4 by high-pressure air. Thereafter, the blank A sent to the rolling machine 8 is formed with a plurality of grooves a ... a on the outer periphery of the large-diameter portion by the fixed flat die 8a and the moving flat die 8b, and the parts are completed.

  As described above, according to the blank supply device 10 of the present invention, the blank A formed in the shaft shape in the previous process is provided on the die 4 in the final process by the high-pressure air discharged from the punch 6 in the final process. It is possible to supply directly to the rolling machine 8 with the direction being surely aligned through the supply passage 11. As a result, it is possible to eliminate the occurrence of dents as in the prior art, simplify the supply mechanism of the blank A from the former 1 to the rolling machine 8, and reliably and promptly supply the blank A with uniform orientation.

  The high-pressure air supply 13 starts discharging high-pressure air at the timing when the forward movement of the blank A into the hole 4 a of the die 4 by the punch 6 in the final process is finished, and the punch 6 moves backward from the die 4. Since the discharge control mechanism 14 that stops the discharge of the high-pressure air at the timing is provided, the punch 6 in the final process can be pushed into the hole 4a of the die 4 in the blank 4 as usual, and the punch 6 can be used in the die 4 as usual. Since the discharge of the high-pressure air is stopped at the timing of retreating, the high-pressure air can be prevented from blowing around the front surface of the die 4 and adversely affecting the transfer of the blank A by the material transfer chuck.

  In the above-described embodiment, the case where the groove a is formed on the outer periphery of the shaft-shaped blank A by the rolling machine 8 has been described. However, in this case, a screw or the like is formed on the outer periphery of the appropriately shaped blank by the rolling machine 8. Of course there may be.
