Abstract

PURPOSE: A wire interlocking supplier is provided to intensify the performance of a device and to prevent an accident by suppressing the unfastening of wire even the periodic stop of a wire drawing bench. CONSTITUTION: In a regular state of a speed of pulling a wire from a wire drawing bench and a rotation speed of a rotary table(11), a dancer arm(19) keeps a balance state. When the wire pulling speed becomes fast, the dancer arm rotates in a clockwise direction. The rotation of the dancer arm is transferred to a cam(30) through a first and a second gear(28,29) and is sensed through a sensor(21). A signal sensed through the sensor is fed to an inverter for controlling a driving motor(14) so that the speed of the driving motor is changed to correspond to the wire pulling speed. The wire pulling speed and the wire drawing out speed of a wire supplying stand(13) are regulated.

Description

Wire interlock supply device

The present invention relates to a wire feeder for supplying a raw material wire from a wire drawing device, and more particularly, a rotary table on which the raw material wire is placed is rotated by a separately installed motor, and detects the degree of pulling the wire from the drawing machine. By controlling the speed, the supply speed of the wire can be properly adjusted according to the degree of wire pulling and the wire supply device can be stopped at the same time when the drawing machine is stopped. The present invention relates to a wire interlock supply device that can be automatically performed.

In general, the wire drawing device is provided with a wire supply device for supplying a raw material wire to the drawing machine, and looks at the structure of such a conventional wire supply device based on Figure 1 as follows.

1 is an exploded perspective view of a conventional wire feeder, as shown in the conventional wire feeder, a rotary shaft 3 having a rotary table 2 mounted on the center of the base 1 at the center of the disc-shaped base 1. It is rotatably installed around the cylindrical support guide (4) installed on the center upper surface of the rotary table 2, the carrier (7) consisting of approximately four vertical support rods (5) and the circular support (6) It consists of a structure that is detachably coupled.

In such a conventional wire feeder, the lead end 8a of the raw material wire 8 is drawn in a fresh machine (not shown) in a state in which the raw material wire 8 in the form of a coil is mounted on the outer circumference of the vertical support rod 5 of the carrier 7. Is supplied.

At this time, the conventional wire supply table is to supply the raw material wire 8 to the drawing machine side while the rotary table 2 is rotated by the force of pulling the raw material wire 8 from the drawing machine.

On the other hand, in general, when drawing work in the drawing machine, while pulling the material wire supplied from the wire supply base, when the drawing length reaches a certain length, the drawing machine is stopped periodically according to the instructions of the counter. However, when the drawing machine is stopped in this way, since the conventional wire supply stand does not have a separate brake system for stopping the wire supply stand in response to the stoppage of the drawing machine, the wire of about 30m is released by the rotating centrifugal force. .

In this way, the wires released from the wire feeder are entangled with each other at the bottom between the wire feeder and the drawing machine, and this phenomenon is repeated at each stop of the drawing machine, so each time the worker releases the tangled wires to the wire feeder. You have to repeat the rewinding.

In addition, the weight of the material wire placed on the wire feeder becomes heavier than in the past, and it has recently reached almost 2 tons. As described above, the wire feeder is installed in an upright state and the center of gravity when the material wire is laid It is located at a high position from the ground bar. When the action of the drawing machine is resumed with respect to the wire feeder, when the force of pulling the material wire acts momentarily high, the wire feeder including the carrier falls and a safety accident occurs. The risk is high.

In addition, the conventional wire feeder does not include a separate brake device or rotation driving means for stopping the rotation of the wire feeder in response to the stoppage of the drawing machine. Therefore, an operator must always wait for each machine. Although the wire supply table is provided with a chain or a rudimentary tension adjusting means around the turntable as a stop aid of the carrier, there is a problem such as severe noise is generated in such a device.

Therefore, the present invention is to solve the above-mentioned problems that are pointed out in the conventional wire supply device, by providing a drive means for imparting a separate rotation driving force to the wire supply device so that the wire supply table operates in conjunction with the drawing machine It is an object of the present invention to provide a wire interlocking supply device that prevents loosening of wires even at periodic stoppages of the drawing machine so that the performance of the device and prevention of safety accidents can be made.

Another object of the present invention is to detect the degree of pulling the material wire from the drawing machine to automatically adjust the speed of the wire supplied from the wire supply in response to the drawing speed of the drawing machine to allow the wire to work smoothly through the drawing machine It is to provide an interlocking supply device.

Looking at the interlocking supply process of the wire in the wire interlock supply device of the present invention having such a structure as follows.

First, in the wire interlock supply device of the present invention, the driving motor 14 is commonly connected to the power supply of the drawing machine, so that the driving motor 14 is also simultaneously driven when the drawing machine is driven, and the drawing machine is driven by the instruction of the counter during the drawing process in the drawing machine. In this case, the electronic brake (not shown) provided in the drive motor 14 is operated to stop the rotation of the wire feed table 13.

Next, a process of maintaining a constant wire supply flux between the wire supply base 13 and the drawing machine is as follows.

When the wire R is drawn out of the carrier 12 during the wire drawing process, the wire R is led to the wire guide 23 through the wire pulling roller 20 of the dancer arm 19 to the drawing machine. (R) is in the pulled state (i.e., a state where a constant tension is applied), so that the dancer arm 19 is exerted a rotation moment toward the wire feeder 13 side, but the rotation moment is in the opposite direction. The balance is maintained by the spring of the tension spring 27 to apply a tensile force to the).

That is, when the speed of pulling the wire R from the drawing machine and the rotational speed of the rotary table 11 are in a constant state, the dancer arm 19 maintains the balance state and there is no movement. If the wire pulling speed is increased, the dancer arm 19 rotates clockwise (in the direction of the wire feeder), and the rotation of the dancer arm 19 is performed by the first gear 28 and the second gear 29. It is transmitted to the cam 30 through the sensed through the sensor 21.

The signal sensed through the sensor 21 is applied to the drive for controlling the drive motor 14 so that the speed of the drive motor 14 is changed to correspond to the wire pulling speed from the drawing machine. Control of the wire withdrawal speed of (13) is made.

On the contrary, even when the wire withdrawal speed from the wire supply base 13 is relatively faster than the wire pulling speed of the drawing machine, the line speed is adjusted through a series of processes through the sensor unit.

Therefore, in the wire interlock supply device of the present invention, even if the wire pulling speed of the drawing machine is changed, the wire withdrawal speed from the wire supply stand is changed correspondingly, so that the wire between the wire supply stand and the drawing machine is always kept in a constant tension. .

As described above, in the wire interlock supply device of the present invention, a separate drive motor for rotating the wire feeder is provided, and the drive motor is controlled by the wire tension state between the wire feeder and the drawing machine. In addition, the following advantages and effects are expected as it is configured to stop and drive at the same time at the time of stopping and driving the fresh machine.

First, since the wire supply from the wire feeder to the drawing machine is made in conjunction with the drawing machine, even if the drawing machine is stopped, no loosening of the wire occurs, so there is no need for a separate manpower around the separate machine. do.

Further, in the present invention, since a heavy pulling force is momentarily prevented from being applied to the heavy chain wire supply stand, there is no risk of the wire supply stand falling down and there is no risk of a safety accident.

Next, the present invention improves the efficiency of the drawing work because the speed of the wire feeder is automatically adjusted according to the speed of the drawing machine, it is possible to improve the quality of the fresh product.
