SU923731A1 - Metal continuous casting machine apparatus for separating dummy bar from ingot - Google Patents

Description

The invention relates to metallurgy, and more specifically to continuous casting machines (CC). *

A device for separating a seed from an ingot is known, having two separate separation and displacement mechanisms, comprising an actuating extrusion roller and an upper support roller mounted on an actuator shaft, which is provided with levers diverting the seed from the ingot after it has been separated [1).

A disadvantage of this device is the complexity of the design, as well as the presence of separate mechanisms with actuators for the separation and displacement of the seed.

The purpose of the invention is to simplify the design, reduce the weight and dimensions of the device, as well as improve reliability.

This goal is achieved by the fact that in the device for separating the seed from the ingot machine continuous

casting blanks containing extrusion rollers, a pushing lever and a shaft mounted on stationary supports, extruding rollers and a pushing lever mounted on a single shaft, made cranked.

FIG. 1 shows a device for separating the seed, side view; in fig. 2 - section A-A in FIG. · 1; in fig. 3 shows a section BB in FIG. 1 \ on the intermediate shaft at the time of separation of the seed when the crankshaft is in the upper position) (in Fig. 4 - the position of the crankshaft at the time of shifting the seed from the ingot.

The device for separating the seed consists of a crankshaft 1, on which the pushing lever 2 and the pressing rollers 3 are mounted. The crankshaft is fixed on stationary supports 4 with bearings 5 and connected to the gearbox 6 by the intermediate shaft 7 by means of couplings 8. Rotation of the crankshaft3 923731 4

the shaft is transmitted from the electric motor 9 ·

The device is designed to separate the seed 10 from the moving ingot 11 cast in continuous casting machines.

In the initial position, the crankshaft 1 is turned down by the pushing lever 2.

When a signal is sent to the separation of the seed 10 from the ingot 11, the electric motor 9 through the gearbox 6 and the intermediate shaft 7 transfers the rotation to the rollers 3 and turns the pushing lever 2 upwards. . 55

In the process of rotating the crankshaft, the extrusion rollers 3 abut the head of the seed 10 and raise it to a height greater than the height of the engaging groove of the seed 10 with the fuse, which separates it from (the ingot during the shaft rotation from the initial position to the contact ' the extruding rollers 3 with the seed head 10, the electric motor 9 accelerates and runs at the moment of separation in nominal mode. The pushing lever 2 in the process of rotating the crankshaft 1 enters the seed head window 10 and upon reaching the shaft edge it upper position abuts the wall of the head box 10. When the seed further rotation of the crankshaft 2 moves the push lever 10 in the direction seeded different livki ₃₅ by a larger amount than the width of the engaging groove 10, the seed 11 with the ingot.

After that, the pushing lever 2 goes out of the window of the head of the seed 10 and stops engaging the ingot 11.

Upon further rotation of the crankshaft 1 returns to its original position.

Thus, for a full revolution of the crankshaft, the seed is separated and shifted from the ingot.

3 the use of the invention greatly simplifies the design of the device, reduces the weight and complexity of manufacturing, reduces the cost of installation and operation, the expected efficiency is 10,000 rubles per device.
