Abstract

PURPOSE:To enable marking of continuous casting piece with a simple structure by utilizing the mass of a marking head and changing its potential energy to kinetic energy to obtain striking energy. CONSTITUTION:A rod 17a is stretched by operating an air pressure cylinder 17, a lever 9 is rotated around a pivot 5 counterclockwise, and a supporting rod 4 is pushed up through a buffer block 18. When the supporting rod 4 is rotated by a specified angle, an air cylinder 16 is operated to stretch a rod 18a, and a positioning claw 15 at the tip is engaged to the pin 11 of a positioning bracket 10, and the supporting rod including a marking head 2 is held at the position. When a continuous casting piece 1 carried on the carrying table 19 and stopped at a specified position, the cylinder 16 is operated to shorten a rod 16a and the claw 15 is disconnected from the pin 11. Then, the head 2 turns clockwise, and a marking stamp 3 strikes against the casting piece 1 to perform marking. At this time, repulsive force is absorbed by the block 18 and bounding of the head 2 does not occur.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a stamping machine for stamping a cast steel type symbol, charge number, etc. on the end or side surface of a continuously cast piece.

Conventional stamping machines of this type are generally configured in such a way that a pneumatic cylinder applies an impact force to the stamping head that houses the printing stamp, causing the head to collide with the slab.
A typical example thereof is constructed as shown in FIGS. 1 and 2. In those figures, 01 is a continuous slab, 02 is a marking head, 06 is a printing stamp, 04 is a pneumatic cylinder, 0
5 each indicates a transport chain.

This kind of stamping machine has a stamping head 02 of 7~8m/se.
The pneumatic cylinder 04 is used to provide an initial velocity of c and an engraving energy of 20 to 30 kfI-m, but the pneumatic cylinder 04 must provide a considerably large initial velocity to the engraving head 02. The pneumatic cylinder 04 and its compressed air system require special consideration because they must have sufficient strength and rigidity to withstand impact, resulting in a complicated structure and high cost. There was a problem with inviting people.

In order to avoid such problems, the present invention utilizes the mass of the marking head, instead of using an air cylinder as a drive source for the marking head, and converts the energy at that position into kinetic energy and uses it as impact energy. It was proposed for the purpose of providing a simple and inexpensive stamping machine for continuous slabs. A support rod whose upper end is fixed to a spindle and a marking head attached to its lower end, and a pneumatic rod whose middle portion is fixed to the rotating spindle, a buffer block is attached to its lower end, and whose upper end is supported by a frame. a lever connected to the tip of the cylinder rod; and a positioning bracket having a base fixed to the rotating support shaft and having a plurality of pins.

This invention relates to a continuous slab stamping machine characterized in that it is supported by a frame and includes a pneumatic cylinder having a positioning claw at the lower end of the rod that can be engaged with the pin of the positioning bracket.

The present invention will be specifically explained below with reference to embodiments shown in FIGS. 6 and 7.

In FIG. 6, 1 is a continuous casting piece that can be fixed at a predetermined position on the conveyance table 19 by a fixing means (not shown), and 2 is a continuous casting piece that can be fixed at a predetermined position on the conveyance table 19, and 2 is a printed stamp 6 as shown in the figure (the imprinted stamping spatula r4 has a lower end that The support rod 4 is fixed to the marking head 2. The upper end of the support rod 4 is formed into a forked shape as shown in FIG. Provided.5
is a support shaft fitted into the boss portion 6.6' at the upper end of the support rod 4, and the support shaft 5 and the boss portion 6.6' are fixed with a key 7.7'. 10 is a fan-shaped positioning bracket fixed to the support shaft 5 with a key 8 as shown in FIGS. 4 and 5, and the bracket 10 has a pin 11 as shown in FIG.
．． 11', 11'' are installed.

Further, both ends of the support shaft 50 are connected to the frame 14°1 of the frame F.
4', it is rotatably supported by bearings 12 and 16 fixed as shown in FIG. 9 is the boss part 9 in the middle part.
a is rotatably supported on the support shaft 5 as shown in FIG. and
Moreover, the tip of the rod 17a of the pneumatic cylinder 17 supported by the frame F is connected with a pin to its upper end.

Reference numeral 16 denotes a pneumatic cylinder supported by the frame F, and a positioning pawl 15 is attached to the tip of the rod 16a of the pneumatic cylinder 16.

One embodiment of the present invention is constructed as described above, and when stamping the continuous slab 1 with this stamping machine, first, the pneumatic cylinder 17 is operated to stamp the rod 17a.
is extended, the lever 9 is rotated counterclockwise about the support shaft 5, and the support rod 4 is pushed up via the block 18, resulting in the state shown in FIG. When the support rod 4 has rotated counterclockwise by a certain angle, the pneumatic cylinder 16 is activated to extend the rod 16a, and the positioning claw 15 at the tip is attached to the pin 11 of the positioning bracket 10 as shown in FIG. The support rod 4 including the marking head 2 is held in the position as shown in FIG.

This stamping machine is on standby in this state, and when the slab 1 is transferred on the conveyance table 19, stops when it reaches a predetermined position, and is fixed at that position, the pneumatic cylinder 16 moves in the above case. The rod 16a is retracted, and the positioning claw 15 at the tip is removed from the bottle 11. Then, the support rod 4 including the marking head 2 is moved to the support shaft 5 by its own weight.
At the same time, the stamp 6 of the stamping spatula 12 collides with the slab 1 to make a stamp. In this case, the stamping spatula) 2 tries to bounce repeatedly due to the repulsive force when it collides with the slab 1, but the repulsive force is absorbed by the buffer block 18 at the lower end of the lever 9 (at this time, the Since it is absorbed by the buffering effect of (), the marking head 2 does not bounce.

In this case, the magnitude of the impact force of the marking head 2 is determined by adjusting the swinging angle (rotation angle) of the support rod 4 by the reno-9 as appropriate, and moving the positioning claw 15 to the positioning bracket 10. Pin 11.11', 11''
It can be adjusted over a wide range (6 steps in this example) by engaging any one of the above.

Since the stamping machine of the present invention has the above-described configuration and operation, according to the present invention, (1) the impact force for stamping the slab 1 of the stamping head 2 is generated by the stamping head 2 itself. The pneumatic cylinders 16 and 17 are simply used to provide positional energy to the marking head 2, and no impact force is applied to them, so these pneumatic cylinders have a simple structure and are inexpensive. A general-purpose pneumatic cylinder is sufficient.

(2) The magnitude of the impact force of the marking head 2 is determined by appropriately adjusting the rotation angle of the support rod 4 in the counterclockwise direction by the lever 9, and by adjusting the rotation angle of the support rod 4 in the counterclockwise direction by the lever 9, and by adjusting the positioning pawl 15 and the pins 11 and 11' of the positioning bracket 10. , 11''. Since the magnitude of the energy at the position of the marking head 2 can be easily adjusted, it can be easily changed depending on the depth, size, etc. of the marking.

(3) The marking head 2 is attached to the support rod 4. Since it is rotatable together with the support shaft 5, it is easy not only to set the position for marking, but also to replace the printing stamp 6 or the marking head 2.

The following practical effects can be mentioned.
