FIELD OF THE INVENTION The present invention relates to a novel apparatus for automatic flange finishing machines, in particular for sheet metal forming of sheet metal steel.

Conventionally, steel sheet metal forming, which is such a steel structure material, is carried out by positioning a workpiece by carrying a workpiece such as a jib craine, etc., into a piece of steel, and positioning it, and processing it to recover it. The manual operation of a series of processes required two or more workers, resulting in a low number of rework.

In addition, since the positioning is performed manually, it is difficult to obtain a high degree of flange machining, and there are disadvantages such as poor safety. SUMMARY OF THE INVENTION The present invention seeks to eliminate such drawbacks in the prior art, to provide a safe, high precision and high efficiency unmanned automatic flange finishing apparatus.

According to the apparatus of the present invention, after automatically aligning a plurality of stacked albows stacked, the operation of importing, positioning, decorating, carrying out, stacking and retrieving by automatic starting is performed continuously. In addition, it is possible to perform an unattended fully automatic flange finishing process that can be automatically and repeatedly completed to stop the processing of the entire process. Next, a suitable embodiment in which the present invention is illustrated in the needle drawing will be described.

The automatic flange wrapping device shown in Fig. 1 (a) and (b) is a surface alignment device (A), a conveying device (B), a positioning device (C), a pressing device (D) and a collecting device for the workpiece. It consists of the elements of (E).

The face alignment device A of the workpiece shown in FIG. 2 (front view) and FIG. 3 (side view) includes two upright columns 2 on the base 1 and an L-shaped frame 3 ) And the hydraulic cylinder (4).

The upright column 2 and the L mold 3 are coupled to the pin 5, and the cylinder 4 couples the base 1 and the L mold 3 to the pins 6 and 7, respectively.

The work piece 8 stacked on the L mold 3 is inclined like a two-dot chain line by the operation of the hydraulic cylinder 4, and slides downwards, and the flange face is formed on the stopper 3 "of the L mold 3. When the surface alignment is completed, the L-shaped frame 3 is returned horizontally by the operation of the hydraulic cylinder 4 after the surface alignment is completed.

(3 ") is the base of the to-be-processed material 8 attached to the L-shaped frame 3. The conveying apparatus B shows the front view in FIG. 4, the side view in FIG. 5, and FIG. 6 the common block. Display the front view.

This conveying apparatus B is comprised from the trolley track F, the trolley G, the drive system hydraulic motor 13, and the screw wire 16. As shown in FIG.

The track frame 9 is located above the front face of the bodyless body D, and is installed between a few flange fitting devices A and a recovery device E, and the vertical rails 10 and 11 at the upper and lower sides and the horizontal rails at the front. (12) is provided.

The hydraulic motor 13 is installed at one end of the track, and the bearing 14 is installed at the other end thereof, and the hydraulic motor 13 is rotated by connecting the screw shaft 16 via the nut 15 of the trolley G. The trolley G can move.

The trolley body has four vertical wheels 21, 21 ', 22, 22' and horizontal wheels 23, 23 ', 24 and 24' and a hydraulic cylinder 17 at the center of the trolley body. Guide rods 18 and 18 'are attached to the common block 19 on both sides thereof. The electromagnet 20 may be mounted on the lower surface of the common block 19 to move the workpiece 8 or the workpiece 8 one by one.

FIG. 7 is a front view of the positioning device C and FIG. 8 shows a plan view of FIG.

This positioning device C is constituted by the elements of the fixed table 25 and the moving table H. As shown in FIG.

It is located in front of the body main body D of the fixed table 25, and the upper surface of a table is the same surface as the upper surface of a pressure bed D '.

The hydraulic motor 26 is arrange | positioned on the upper surface of a table, and the screw shaft 27 and 27 'are installed in the left-right symmetry.

The screw shafts 27 and 27 'are supported on the fixed table 25 and the pressure bed D' by the bearings 28, 28 ', 29 and 29', and the hydraulic motor shaft 26 The sprockets 30 and 30 'and the sprockets 31 and 31' on the screw shafts 27 and 27 'are connected to the transmission chains 32 and 32' to transmit the rotational force and move. Coupling with the nuts 33, 33 'of the table H.

The moving table (H) moves on the stationary table (25) and the footless bed (D '), the support neck (34), the support frame (35), the positioning stopper (36), the magnet cylinder (37), the frame ( 38).

The support frame 35 is equipped with a positioning stopper 36 of the work piece 8 on the upper surface of the support frame 35 fixed to the upper surface of the support neck 34 and screwed with the hydraulic motor 39 at a position corresponding to the size of the flange. The shaft 40 can be rotated and moved. The frame 38 is fixed to the front frame 35.

The hydraulic cylinder 41 is horizontally fixed to the center thereof, and the electromagnet 37 is attached to the cylinder piston 42.

The suction surface of the electromagnet 37 is the same surface as the upper surface of the frame 38. The base 43 of the electromagnet 37 slides the guide shoe 44 in the frame 38 so as to be able to perform horizontal movement by the operation of the hydraulic cylinder 41.

The workpiece 8 mounted on the frame 38 by the trolley G is sucked by the electromagnet 37 and the hydraulic surface of the workpiece 8 is placed on the positioning stopper 36 by the operation of the hydraulic cylinder 41. You can make a decision.

The workpiece 8 positioned on the movement table H moves by the rotation of the screw 27, and moves and automatically stops until the center of the mold 45 and the support frame 35 coincide.

Simultaneously with the automatic stop, the mold 45 descends and demagnetizes immediately before contacting the workpiece 8, releases the adsorption state, and the workpiece 8 is processed. As the die 45 rises, the workpiece 8 comes into contact with the upper surface of the frame 38 of the moving table H by gravity.

It adsorb | sucks again with an electromagnet 37, it moves to the origin from the press D by the reverse rotation of the screws 27 and 27 ', and automatically stops. At the same time as stop, demagnetization is performed and adsorption is released.
