DETAILED DESCRIPTION OF THE INVENTION This invention provides a metal plate with another metal plate.
I Cut the end of a metal plate to make contact, contact another metal plate with the cut surface, and automatically weld V
= okiniguchi, II zuro.

31 pieces, Kinka brake 1, pull for flange / -) ξ
In order to weld, if we do the actual welding immediately, it will be distorted, so we first perform temporary welding and then weld the actual welding. In temporary welding, a metal plate is cut to make the welding surface flat, one person holds the flange plate in contact with the cut surface of the metal plate, and another person temporarily welds multiple locations. At this time, in order to temporarily weld at the correct position τ, during the temporary welding process,
The person who maintained the flange plate in contact with the flange plate corrected its position by hitting the flange plate with a hammer or the like.

The actual welding was done as a separate plastic work for the temporarily welded parts. As described above, the conventional process is labor-intensive, time-consuming, complicated, and has the disadvantage of tiring the workers due to high heat, hammering, etc.

This invention adds another metal plate to the conventional metal plate←
The present invention aims to improve the above defects in the process of welding a four-piece welding plate, and to provide a device that automatically performs plate cutting and temporary welding or main welding.

■Mechanism for cutting the main body plate, ■Mechanism for moving the lower blade away from the cutting surface of the main body plate after cutting the main body plate, ■Mechanism for bringing the metal piece plate for the flange into contact with the cutting surface of the main body plate, ■Main body It consists of a mechanism for welding the plate and the piece plate, and each of the above mechanisms is wired and connected to a push button on a control panel, and by pressing the push button, each of the mechanisms from ■ to ■ above is activated individually or in succession. This makes it possible to automatically cut the main body plate and weld the piece plate.

The details of this invention will be described below with reference to the automatic metal plate cutting and welding apparatus for cutting the main body plate of a liner plate and welding the piece plate, as shown in the drawings.

In order to increase the strength of the main body plate 1, the liner plate is made into a wavy shape as shown in FIG. 1, both sides are bent 90 degrees to attach flanges, and piece plates 2 for flanges are welded to both ends to form a box shape.

Some have a 7-rat bottom, but more often the bottom is curved into an arc. When the main body plate 1 is corrugated and curved in this way, the ends of the main body plate are uneven, and in order to weld the piece plate 2, the end of the main body plate 1 has to be cut so that the piece plates are in close contact with each other. must be done. 4 is an upper blade for cutting the end of the main body plate 1, and 5 is a lower blade, which has a wavy shape that matches the wave shape of the main body plate 1. The upper and lower blades for cutting the edges of a plate whose bottom surface is not wave-shaped do not need to be wave-shaped. σ4 is a cylinder for raising and lowering the upper blade, and 05 is a cylinder for operating a cam 5' to raise and lower the lower blade. In the figure, cylinders 06 and 06 are provided on both sides of the front surface of the lower blade 5, so that when the pin 6 is projected and retracted, it is fitted into the bolt hole 6 of the main body plate 1.

is a main body plate presser holder, and a plurality of them are provided. The roller 8' is raised and lowered by the cylinder 08, and lifts and supports the main body plate 1 so that it comes into close contact with the lower blade. A cassette 9 for stacking and storing piece plates 2 is provided on the back side of this device, and an arm 10 is protruded by a cylinder 010 to make it possible to send out the lowest piece plate 2 to the left in FIG. 3. Magnet 1 raised and lowered by cylinder 011 to a position above sent-out piece plate 2
1, turn the magnet 90 degrees, and magnet 1
Magnetic reversal cylinder 011 for bringing the piece plate 2 attracted to the main body plate 1 into contact with the cut surface of the main body plate 1
will be established. A plurality of torch mounting arms 12 are provided above the cut surface position of the main body plate 1, and the torch mounting arms 12 are raised and lowered by the torch lifting cylinder 012, and the torch (not shown) mounted on the torch mounting arms 12 is mounted on the plate 1. and the plate 2, and enable temporary welding or actual welding by applying electricity.

Each cylinder of this device is hydraulic or pneumatic, electrically wired (not shown), and activated or deactivated by a switch (not shown). These switches can be integrated into a control box so that the switches can be opened and closed using push buttons.

When using the automatic metal plate cutting and welding apparatus according to the present invention, the main body plate 1 is conveyed between two bins 6 by a conveyor or a trolley, and the cylinder 06 is actuated to move the bin 6 to the main body plate 1. When the cylinder 06' is moved in the direction of the upper and lower blades, the main body plate 1 is also moved in the direction of the upper and lower blades at the same time. At this time, by adjusting the moving distance of the cylinder C6 in advance, the distance between the cut surface of the main body plate 1 and the bolt hole 3 can be specified, and a liner plate according to the specified specifications can be manufactured. When the end of the main body plate 1 is conveyed between the upper blade 4 and the lower blade, the cylinder 08 is actuated to raise and support the main body plate 1 with the roller 8', and the cylinder 07 is actuated to remove the main body plate 1. The presser foot 7 is lowered, and the main body plate 1 is held between the main body plate presser 7 and the main body plate receiver 8 to prevent the main body plate 1 from moving. Next, the cylinder 04 is operated to lower the upper blade 4 to cut the end of the main body plate 1.

After cutting the end of the main body plate 1, the cylinder 04 is operated to raise the upper blade 4 while the main body plate 1 is being held between the main body plate holder 7 and the main body plate receiver 8, and the cylinder C5 is operated to raise the cam 5. ' to lower the lower blade 5, actuate the cylinder 10, and use the arm 10 to push out the bottom piece of the piece plate stacked in the cassette 9 below the magnet 11; Bring the piece plate 2 close to the top and attract the piece plate 2 to the magnet, and then attach the cylinder 01.

When used as is, the piece plate 2 can be automatically contact-welded to the main body plate 1 in a short period of time.Therefore, there is no need for two people to perform temporary welding while correcting the contact state with a hammer as in the past, which requires less manpower. Since the lower blade is separated from the cutting surface of the main body plate 1 during welding, there is no risk of the lower blade becoming burnt back due to the heat during welding, and all liner plates using the temporary welding method have the same dimensions and are in the same condition. This enables the actual welding to be performed by a robot. In addition, by holding the weld, it is possible to perform not only temporary welding but also actual welding. The above description of the embodiment relates to an automatic metal plate cutting and welding device for cutting the edge of a liner plate and welding a flange plate, but the present invention is not limited to edge cutting and welding of a liner plate. It can also be used for welding the side plates of metal master molds or box-shaped containers for various purposes, or for welding other pieces to the cut surfaces of 11, 1τ9J in general.

In this way, the present invention has excellent effects.
