Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a billet vertical position adjustment device in a forging forming roll. It is.

0002

[Conventional technology and its issues]

Generally, in a rotary forging machine, the billet material is formed into a mold with a mold recessed on the outer circumferential surface. Clamp between the shaped roll and smooth roll 4 to 5 times with the tongs of the manipulator. It is passed through and molded. In order to efficiently perform such molding processing, once the molding The billet is passed through the forming rolls in the opposite direction while being clamped to the tongs. The billet is then returned to its original supply position and molded again. The applicant is When performing this return operation, the rear end of the billet touches the fixed gag provided just before the forming roll. proposed a device that prevents contact with the end of the (see publication).

0003 In other words, between the forming rolls and the billet supply conveyor, there is a A lifting guide is provided, and this lifting guide is fixed to the upper end of the inclined slide. The ride is inserted into the fixed guide tube and slides, and the lower end of this slide can be swung. If the billet is connected to a cylinder with the function of The billet is raised by the action of the cylinder and aligned with the conveying surface of the billet supply conveyor. Then, the billet is fed, clamped by tongs, and stretched and formed. When the billet is clamped to the tongs, the cylinder lowers the lifting guide. down. Also, while the billet is clamped to the tongs, it can be moved in the opposite direction to the forming roll. When returning to The proposal is that the return work can be done without colliding with the vehicle.

0004 On the other hand, recent automatic rotary forging machines are moving from small-product mass production to high-mix, small-lot production equipment. In contrast, the size range of molding materials has been greatly expanded. However, the above episode The lifting guide in the rolling forging machine is a channel-shaped trough 10a as shown in FIG. Since the billet size is changed, the amount of correction a in the height direction and the correction amount a in the width direction are If the amount of correction b becomes necessary, the problem is that the trough 10a is replaced every time the change is made. There was a problem.

[0005]

[Means to solve the problem]

Therefore, the present invention solves this problem and provides a lifting guide suitable for automatic forging equipment. It was devised for the purpose of providing forging forming rolls. and the billet supply conveyor, which guides the billet in the longitudinal direction and can be raised and lowered. A flexible lifting guide is provided, and the lifting guide is composed of a V-shaped trough to move the billet there. A forming roll characterized in that the forming roll is fed to the forming roll with its cross-sectional diagonal line in the vertical direction. The vertical position adjustment device of the billet in the billet is also In addition to raising and lowering the billet by means of a cylinder, the fluid cylinder is controlled according to the billet size. A device for adjusting the vertical position of a billet in a forming roll according to claim 1, characterized in that: be.

【Example】

The structure and operation of the present invention will be described in detail with reference to embodiments shown in the accompanying drawings. Figure 1 is a control system diagram of an embodiment of the present invention, Figure 2 is an overall side view of this embodiment, and Figure 3. 2 is a cross-sectional view of a main part of this embodiment, and is a cross-sectional view taken from A in FIG.

[0007] This example is used for automobile parts such as crankshafts, front axles, counter gears, etc. Suitable for automatic rotary forging machines that form and process forged products, and the manifold used here The purator is preferably a rail-running manipulator.

[0008] An overview of the lifting guide in the automatic rotary forging machine of this example is shown in Figure 2. On the billet 1 supply side of the forming roll 2, there is a gap between the billet supply conveyor 20 and the billet supply conveyor 20. An elevating guide device 3 is provided, and this elevating guide device 3 is connected to a trough 10, which will be described later. and a slide 4 that supports this trough 10, and this slide 4 is slidably fitted inside. The guide cylinder 5 and the lower end of this slide 4 are connected and can be swung by a pin 6. It consists of a freely supported hydraulic cylinder 7, which is the same as the above-mentioned known example. It looks like this. In addition, 8 supports the tongs of the manipulator, and 9 supports the guide tube 5. Showing the stand.

[0009] Here, in this embodiment, the trough of the lifting guide device 3 is specifically a V-shaped trough. 10, and the billet 1 is guided and supplied to the forming roll 2 with its cross-sectional diagonal line being vertical. I am trying to provide for them. Therefore, when changing the billet size, the height It is only necessary to adjust the correction amount a in the direction (see FIG. 3). And this height correction This is done using the following control system.

0010 That is, in FIG. 1, the hydraulic cylinder 7 includes an engine composed of electromagnetic elements. A coder 11 is built in and detects the operating position of the rod 12. This hydraulic The cylinder 7 is configured to be double-acting, and these oil pressure supply paths 13, 13 are connected to check valves. It is connected to the electromagnetic valve 14 via a flow control valve. This solenoid valve 14 is a hydraulic power source 15 This solenoid valve 14 is connected to the position controller 16 for its solenoid coil. The excitation is controlled by applying the signal. This position controller 16 - Signals from the detector 11 and position detection amount amplifier 17, and signals from the position setting device 18 is now entered. Therefore, the target value can be set using the position setting device 18. When the coil is turned on, the coil of the solenoid valve 13 is energized via the position controller 16, and the hydraulic series is activated. The printer 7 operates according to the set values. And the stopping position of the rod 12 of the hydraulic cylinder 7 The position is detected by the encoder 11, the detected value is fed back, and the necessary It is possible to move to the desired position and maintain the required position. Also, this position setting device If 18 is linked to a central processing unit (not shown), settings suitable for the product will be automatically made. can.

[0011] In this embodiment, an encoder is used to detect the position of the rod 12 of the hydraulic cylinder 7. Although electrical control is performed using rod 11, the present invention is not limited to this. A connecting fitting 19 that connects the slide 4 (for example, a T-shaped fitting fitted with a dovetail groove) ), and when this branch comes into contact with the screw-type stopper, Make sure that the hydraulic cylinder stops operating, and adjust the position of this stopper to the billet size. It may also be mechanically adjusted depending on the amount of water. In addition, although the elevating guide device of this embodiment is designed to ascend and descend obliquely, in this embodiment The idea is not limited to this, and it may simply be moved up and down in the vertical direction.

[Effect of the idea]

According to the present invention, since the lifting guide is configured with a V-shaped trough, billet size If you change the height position of the lifting guide, you can adjust it to the forming roll simply by adjusting the height position of the lifting guide. This improves preparation efficiency. In addition, the lifting guide can be raised and lowered using fluid. Since it is performed using a cylinder, the height position of the billet can be easily controlled mechanically or electrically. can.
