Description

[Detailed Description of the Invention] The present invention relates to an improvement of a material insertion and positioning device in a rolling forming processing machine such as a cross rolling machine.

As for conventional equipment, Japanese Patent Publication No. 53-20462 "Method for inserting and positioning material in rolling forming machine"
As described in the specification, the positioning device that inserts and fixes the material between the upper and lower forming rolls inserts the material to be processed between the upper and lower cross rolling rollers (hereinafter referred to as forming rollers), and positions the material for transportation. There is a device that uses a cylinder rod for material input and a cylinder type stopper to narrow the material and transport the material to a predetermined position, but such a device has a drive device for pushing the material, and a material positioning drive device in the fixed part. Furthermore, since it is equipped with a drive device for a stopper and three fluid pressure cylinders, the structure of the entire device is very complicated, and there are disadvantages in that it takes time to maintain and inspect the mechanical device.

The present invention improves the above drawbacks and has a simple structure that inserts and fixes the material between the upper and lower forming rolls of a cross rolling machine using an extremely simple device and a rod moved by a single hydraulic cylinder and a spring. It provides:

The rolled material positioning device according to the present invention will be explained below with reference to FIGS. 1 to 6.

1 is the upper forming roller, 2 is the lower forming roller,
Consists of a ring, drum and die.
1a and 2a are rings, 1b and 2b are dice, 1
c, 2c are the drums, the die is installed on the ring, and the ring is fixed to the drum with screws 1d, 3a, 3b... indicate the movement of the materials, and 3 is the finished product, the shaft. 4, which indicates the material, is an intermediate plate provided between the upper and lower forming rollers on the material input side. Reference numeral 5 denotes a material holding device, which is composed of a stopper plate, a stopper, etc., and is attached to the ring 2a with a screw 1e. That is, 5a is a block, 6 is a part of the block 5a and a stopper 7 is provided, 7a is a stopper shaft, 7b is a stopper spring, 8 is a stopper plate, 8a
is a mounting screw, the stopper plate 8 is attached to the block 5a so that it can be adjusted left and right, 9 is a cylinder, 10 is a transfer rod which is directly connected by a link, 10a is a spring, and 11 is a limit switch that connects rod 7. Detects movement.

To explain the operation in the above configuration, the heated material 3a that has been conveyed onto the intermediate plate is pushed by the transfer rod 10 by the action of the transfer cylinder 9, and passes over the intermediate plate 4 and stopper plate 8. , as shown in Figure 4B, stopper 7
Then, the spring 7b is compressed by the pressing force of the cylinder 9, and the limit switch 11 is activated.
When the transfer rod 10 is further moved backward by the action of the cylinder 9, the material 3c is pushed by the spring 7b and hits the stopper plate 8, and the material 3c is pushed back by the action of the cylinder 9.
The material 3d is moved to the position shown in d. At this position, the material 3d is held by the stopper plate 8 and the stopper 7, and the limit switch 11 is turned on as shown in FIG. In this state, the forming roller starts operating, and the material 3d is processed by the dies 1b and 2b of the forming roller, and is transferred to the next process as a completed material.

As explained above, the device of the present invention has a stopper plate and a material holding device consisting of a stopper at the end of the lower roller of the forming roller, and a hydraulic cylinder for transfer is provided on the intermediate plate of the forming roller. With a simple device, the material is fixed between the stopper plate 8 and the stopper 7 with the spring 7b, so positioning accuracy is high and the material can be positioned reliably, and the material can be processed automatically in a short positioning time, preventing equipment failure. It is an extremely effective device that requires almost no maintenance and can be done in a short period of time.
