The present invention relates to a wire processing apparatus for a bogie used when replacing a mold in a press, and more particularly, to improve the structure thereof to prevent the wire from being broken.

In general, in order to replace the mold of the heavy body in the press die, the rail is installed on both sides of the press, and the rail moves along the rail to install a trolley for transporting the mold.

Therefore, the mold of the weight body mounted on the press is separated on the empty bogie, and then the bogie is moved to the rear of the press, and the bogie on which the new mold is placed is moved to the press side.

When the moved bogie is stopped in the correct position by the limit switch, the slider is lowered to the bottom dead center and stopped in the state of being connected with the upper die, thereby clamping the upper die to the slider.

After that, the slider is raised to the initial state, and the baggage truck is returned to the initial state, so that the mold replacement work is completed.

In order to move the trolley automatically when the mold is replaced, power must be supplied to the trolley.

Conventionally, as shown in FIGS. 1 to 4, the housing 2 is installed at one side of the installation position of the press 1 so that the first pulley 3 and the fourth pulley are positioned in the housing 2. The second pulley 4 was installed side by side on the mounting plate 5 so as to be elevated, and a weight 6 was fixed to the lower portion of the mounting plate 5.

In addition, the fixing pulley 7 is obliquely installed at an upper portion of the housing 2 such that the fixing pulley 7 is obliquely installed as a third tile, and the wire 8 drawn through the insertion hole is wound around the first pulley 3 and then the fixing pulley 7 and the second Pulled out through the pulley (4).

And the electric wires 8 thus released were fixed to the guides and bars along the outside of the rail 9 and then connected to the motor 11 mounted on the trolley 10.

Therefore, when the trolley 10 moves to replace the mold, the wire 8 fixed by the guide and the rain is pulled on the trolley 10, so that the mounting plate 5 is raised along the housing 2 to transfer the amount of the trolley 10. Compensation for the length of the wire (8) by.

At this time, the weight 6 fixed to the mounting plate 5 serves to make the wire 8 always tense.

This is to prevent the wire 8 from being worn and broken by causing tension of the wire 8 and causing friction with the bottom surface when the trolley 10 moves.

On the other hand, when the conveyed trolley 10 is returned, the mounting plate 5 is lowered like the dashed line in FIG. 2 according to the weight of the weight 6 by the amount returned, so that the wire 8 always has a constant tension.

However, such a conventional device, as well as the driving force of the bogie 10 and the force of the first and second poly (3) (4) and the weight (6) maintaining the tension of the wire (8), as well as the reverse of the replacement Even when the tension is generated in the wire 8 by the driving force of the motor 11 there was a problem that the wire 8 is easily disconnected.

The present invention has been made to solve such a problem in the prior art, and has the purpose of preventing the wire from being broken even when used for a long time so that the tension is not applied to the wire for supplying power to the motor.

According to an aspect of the present invention for achieving the above object, the power supply to the motor by connecting the bogie moving along the rail by the drive of the motor, the space portion formed on one side of the rail, the power supply and the motor through the space portion Provided is a wire handling device for a trolley for a mold replacement consisting of a wire bay supplying device.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 5 to 8 of the accompanying drawings.

5 is a plan view showing the device of the present invention, FIGS. 6 and 7 are cross-sectional views taken along line D-D and E-E of FIG. 5, and FIG. 8 is a cross-sectional view taken along line F-F of FIG.

According to the present invention, a space portion 12 is formed at one side of a rail 9, and the space portion 12 has a cable veyor for supplying power to the motor 11 driving the truck 10. ) Is installed and one end is connected to the motor 11, the other end is connected to the power supply (not shown).

The end of the wire carrier 13 connected to the motor 11 side is fixed to the connection bar 14 fixed to the trolley 10 and the wire 8 drawn from the wire bay 13 is the trolley 10. Is fixed to the clamp 15 and connected to the motor 11.

On the other hand, it is possible to drive the open bogie 10 to the upper portion of the space portion 12 formed on one side of the rail (9), but foreign matter enters into the space portion 12 during the operation to interfere with the bending operation of the wire bearing (13). In order to prevent the worker from falling out or the like, it is necessary to close the space 12.

However, when the space 12 is completely closed, as the movement of the trolley 10 causes the interference with the connection bar 14 and the wire bearing 13 fixed to one side of the trolley 10, It should have a structure in which the closed part is opened by movement.

To this end, a plate 16 having a triangular cross section is fixed to one side of the trolley 10 and a plurality of covers 17 connected to the upper surface of the plate are hinged 18 on the upper portion of the space 12. It is designed to be rotatable around.

The reason why the cover 17 is formed in plural is to prevent foreign substances or workers from falling into the space 12 by opening only the cover 17 of the portion where the plate 16 is located when the trolley 10 moves. to be.

On the opposite side of the hinge 17 of the cover 17 which closes the said space part 12, the rail 9 is caught by one end and is supported.

Referring to the effects of the present invention configured as described above are as follows.

First, as shown in FIGS. 5 and 6, when the trolley 10 is located in an initial state, the wire bay 13 is fully extended to be accommodated in the space 12 and connected to the plate 16. Only the cover 17 is slightly open.

In this state, in order to replace the mold, a mold (not shown) to be replaced on the trolley 10 is applied to the motor 11, and then the power supply is connected to the power supply unit 13 and the wire carrier 13 and the wire ( Power is supplied to the motor 11 through 8) so that the trolley 10 moves along the rail 9.

As the trolley 10 moves in this way, the wire carrier 13 that has been unfolded is bent and gradually folded, and the position of the plate 16 fixed to the trolley 10 is variable, so that the cover 17 placed on the plate 16 is changed. ) Is opened in turn, and the cover 17 removed from the plate is closed by its own weight to close the space 12.

When the trolley 10 is moved to the press side to complete the replacement of the mold and the motor 11 is rotated in reverse, the folded wire carrier 13 is gradually opened and the cover 17 is opened and closed sequentially. Since the initial state as shown in the sixth degree, it is possible to continue the molding work using the press.

As described above, the device of the present invention forms a space portion 12 on one side of the rail 9, and the wire bay 13 for supplying power to the motor 11 is installed in the space portion. As the wire is disconnected due to the movement of the tool, there is no need to replace it, which reduces the mold replacement time.

In addition, since the plate 16 is to open and close the cover 17 in sequence with the movement of the trolley 10, it is also possible to obtain the effect of promoting safety during work.
