Description

TECHNICAL FIELD [0001] The present invention relates to a device for delivering a metal plate,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a metal plate material delivery device, and more particularly, to a metal plate material delivery device for delivering continuously supplied plate materials one by one to a press die.

Although there are various methods of forming a metal article having a three-dimensional shape, a general method of processing a thin plate shape is to use a press die. A press mold is formed by placing a supplied metal plate on a metal mold and applying pressure to plastic deformation to form a three-dimensional metal product.

In recent years, automation systems have been widely established to improve productivity and prevent accidents. Therefore, the metal plate material is supplied to and discharged from the press mold by the automatic equipment.

The metal plate P placed on the base 101 is first supplied to the transfer device 107 by the first loader 105 equipped with the adsorption pad 103. The transfer device 107 carries the supplied metal plate P to the adjacent position of the metal mold 111 while linearly moving along the rail 109.

Then, the second loader 113 having the adsorption pad 103 'grasps the metal plate P' and seats it in the metal mold 111. The molded metal product P "is taken out of the mold 111 by an unloader (not shown). Such a series of operations is performed at a high speed in succession.

A transfer plate 115 is provided on the upper surface of the transfer device 107. The metal plate P should be supplied at the correct position on the transfer plate 115 and its supplied position should not move. So that it can be seated at the correct position of the mold 111.

However, since the transfer device 107 moves at a high speed, the overlying metal plate P 'can be moved and moved during the movement. Accordingly, in order to prevent this, a plurality of paddles 117 are installed on the transfer plate 115 so as to match the shape of the metal plate P '. The abacus 117 is adjustable in position along the slot 119 and is thus adjustable in position according to the specific shape of the metal plate. Therefore, the position of the abdomen 117 must be set each time the metal plate material is changed.

This task was very cumbersome and slowed down the work. When several production model changes are made in a day, the time required for such a setting is a major factor in productivity deterioration.

Korean Patent Application No. 10-1996-0078774

It is an object of the present invention to improve work productivity by not requiring a preliminary work for setting the positions of the paddles for each product having different shapes when transporting the metal plate between the end sections through the transfer plate .

The above object is achieved by an automotive mold equipment for producing a three-dimensional metal product by press-forming a metal plate material; 1. A transfer device for transferring a metal plate to an adjacent position of a mold by moving the metal plate in a planar state with the metal plate on the mold being placed on the mold;

A base frame that runs along the rail; A transfer plate fixed to the upper surface of the base frame and providing a seating surface on which the metal plate is seated; And a plurality of electromagnets fixed to the transmission plate to fix the metal plate placed on the seating surface by a magnetic force.

According to an aspect of the present invention, the electromagnet includes:

A plurality of mounting holes formed in the transmission plate to sandwich the electromagnets;

And a fixing plate fixed to the bottom surface of the transmission plate so as to support the bottom surface of the electromagnet fitted to the installation hole.

According to another aspect of the present invention,

Said transfer plate being in the shape of a cross; The transmission plate may be provided with a plurality of air holes.

According to still another aspect of the present invention,

According to the present invention, it is possible to fix the metal plate to the correct position by using the electromagnet or the adsorption pad. Therefore, in the prior art, there is no need to provide an abdomen for fixing the position of the metal plate, and it is not necessary to perform a preliminary work for setting the position of the abdomen for each of the products having different shapes. Therefore, it is possible to shorten the working time and improve the productivity.

2 is a top view of a delivery device in the prior art.
3 is a perspective view of a delivery device according to an embodiment of the present invention.
4 is a cross-sectional view taken along the line AA in Fig.
5 to 6 are plan views of a delivery apparatus according to another embodiment of the present invention.
7 is a cross-sectional view taken along the line BB in Fig.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. One embodiment will be described with reference to Figs. 3 to 4, and other embodiments will be described with reference to the remaining drawings.

The transfer device 1 includes a base frame 3 and a transfer plate 5 mounted thereon. A plurality of electromagnets (7) are fixed to the transmission plate.

The transmission plate 5 is in a cross shape. This has the purpose of losing weight for weight reduction. When the transfer plate 5 is made lightweight, inertia is reduced, so that it can be started accurately and quickly with less energy. On the transfer plate 5, a vent hole 9 is drilled. This vent hole 9 is for preventing the air from escaping in the direction of the arrow when the metal plate P touches, so that no lift is generated therebetween (see FIG. 4). The vent hole 9 is also preferable for cooling the transmission plate 5.

The transfer plate 5 may be lightweight and made of aluminum with a good heat transfer coefficient, and its thickness T may be 10 to 20 mm.

The electromagnet 7 has an elongated bar shape and an electromagnet mounting hole 11 is formed in the transmitting plate 5 for the installation of the electromagnet 7. [ The electromagnet 7 is fitted and fixed to the electromagnet mounting hole 11 by caulking or silicone and a fixing plate 13 for holding the electromagnet 7 is fixed to the bottom surface of the transmitting plate 5 with bolts Reference). As shown in FIG. 4, the upper surface 7a of the electromagnet may be positioned 0.3 to 1 mm lower than the upper surface 5a of the transmission plate. This is to prevent the metal plate material P 'from directly touching the electromagnet 7 so as to prevent impact or damage to the electromagnet.

The arrangement of the electromagnet 7 can be modified in any way. The number or size can be modified as needed. The electromagnet 7 is intended to fix the metal plate P 'by a magnetic force. As soon as the first loader 105 (see FIG. 1) releases the metal plate P ', the control unit senses the moment and supplies power to the electromagnet to generate magnetic force.

When the transmission device is stopped and the second loader 113 (see FIG. 1) is detected to be lowered, the control unit cuts off the electric power supplied to the electromagnet 7, and extinguishes the magnetic force. The metal plate P 'is transferred to the position where the second loader 113 is installed in a state where the metal plate P' is fixed to the place where the first loader 105 is seated by the magnetic force of the electromagnet 7. The transfer plate 5 may be flat and has a sufficient width and may be provided with any metal plate P having various shapes.

Hereinafter, another embodiment of the present invention will be described with reference to FIG.

The transfer plate 7 can be made up of several groups. A first electromagnet 7 'capable of generating the largest magnetic force is arranged in a cross shape, a second electromagnet 7' 'capable of generating a medium magnetic force is arranged in a cross shape on the inside thereof, A third electromagnet 7 "'capable of generating the smallest magnetic force can be disposed. The first, second and third electromagnets 7 ", 7" and 7 "'may be individually activated in groups. have.

This is for maneuvering the electromagnets in various ways for metal sheets of various sizes and weights. According to this, the use energy can be reduced and the heat generation problem can be reduced. This embodiment is proposed because it is not necessary to operate all the electromagnets in order to hold a small and light metal plate.

FIG. 6 is a plan view of a transfer plate 5 according to another embodiment of the present invention, and FIG. 7 is a cross-sectional view taken along line B-B thereof.

According to this embodiment, the adsorption pad 15 using vacuum pressure together with the electromagnet 7 is used for holding the metal plate P '. This is a method for reducing the heat generation problem due to the use of the electromagnet 7. The number of the electromagnets 7 is reduced and the insufficient gripping force is compensated by the attraction force using the adsorption pad 15. [ This will greatly improve the heat generation problem. An installation hole 11 is provided in the transfer plate 5 for installing the adsorption pad 15 and the adsorption pad 15 is fixed to the installation hole 11 'through the bracket 17. The upper end 15a of the adsorption pad may protrude 0.5 to 1 mm above the upper surface 5a of the transfer plate.

Elastic means can be interposed to cause the adsorption pad 15 to elastically start in the vertical direction when the metal plate P 'is touched. It goes without saying that a vacuum pump 19 is connected to the adsorption pad 15. The adsorption pad 15 can be on / off controlled together with the electromagnet 7 by a control part.

Hereinafter, another embodiment of the present invention will be described with reference to Figs. 1 and 3. Fig.

In some cases, a permanent magnet (not shown) may be used in combination with the electromagnet 7. The electromagnet 7 takes charge of 70 to 80% of the total holding force required and the remaining 20 to 30% of the total holding force is made by the permanent magnet. The second loader 113 can easily separate and remove the metal plate P 'held by the permanent magnet from the transfer plate 5 in a state in which power is not supplied to the electromagnet 7. [

The configuration shown and described above is merely a preferred embodiment based on the technical idea of the present invention. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention. And each of the above-mentioned embodiments may be implemented in random combination even if not mentioned, and any combination is included in the scope of the present invention.
