The operation principle of invention is summarized as follows:
The oil pipe clip plate rack of the light truck-type of such east wind is made up through punch process of the ST12 cold-reduced sheet that 2.0mm is thick, just can be used for the processing of blanking bending composite die after blanking procedure:
The first step, by automobile drive axle U-shaped oil pipe clip plate rack blanking bending composite die of the present invention, is arranged on single-point open type steam-operating 100T forcing press.
Second step, as shown in Figure 2, oil pipe clip plate rack blank 9 after blanking procedure to be placed on above lower stripper 13 inner chamber and the discharging covered completely in the middle of it is stepped down, and to make the guiding pin stop 14 that the front end face of oil pipe clip plate rack blank 9 nestles up anterior location pin stop 14, left end face nestles up left side.
3rd step, start forcing press and punch process is carried out to oil pipe clip plate rack blank 9, on lathe, workbench is with blanking die 6, bending punch 7 and loading and unloading material bar 1 move downward, first when loading and unloading material bar 1 contacts with oil pipe clip plate rack blank 9, loading and unloading material bar 1 can move upward in the process, then be that blanking die 6 contacts with oil pipe clip plate rack blank 9, then be lower stripper 13 with lower discharging rubber 15 because compression thrust upwards and pin stop 14 and oil pipe clip plate rack blank 9 move downward, meanwhile descend discharging push rod 11 with lower discharging spring 12 because of compression thrust upwards together with oil pipe clip plate rack 8 along with bending punch 7 moves downward, until workbench runs to bottom dead centre on lathe, make oil pipe clip plate rack 8 at blanking die 6, complete blanking under bending effect between punch 7 and blanking bending compound die 10 and bend, reach blanking width 24mm, blanking hypotenuse angle 106 °, bending width 25mm, bending height 12.5mm, bending circular arc R 2mm, after blanking bending, the structure of workpiece is as Fig. 3, shown in Fig. 4.
4th step, forcing press upper table wears blanking die 6, bending punch 7 and loading and unloading material bar 1 upwards return, be subject to the resistance of the horizontal discharge arm on lathe top when loading and unloading material bar 1 in the process then move downward and the oil pipe clip plate rack 8 after bending is shot down downwards the outer mold surface of bending punch 7, discharging push rod 11 is meanwhile descended to be ejected from the inner chamber of blanking bending compound die 10 by oil pipe clip plate rack 8 because compression thrust upwards moves upward with lower discharging spring 12, oil pipe clip plate rack blank 9 and blanking bending compound die 10 to be separated because compression thrust upwards and pin stop 14 and oil pipe clip plate rack blank 9 move upward with lower discharging rubber 15 by lower stripper 13.
5th step, with oil pipe clip plate rack blank 9 by horizontal for oil pipe clip plate rack 8 good for the punching upper surface dialled laterally from lower stripper 13, and loads in body feed tank.
The oil pipe clip plate rack appearance and size adopting automobile drive axle U-shaped oil pipe clip plate rack blanking bending composite die of the present invention to make is stabilized in blanking width 24mm, blanking hypotenuse angle 106 °, bending width 25mm, bending height 12.5mm, bending circular arc R 2mm, the uniformity of monnolithic case is regular, sustainablely stable guarantees that oil pipe clip plate rack profile reaches the designing requirement of product drawing.While improving the quality of products, also improve production capacity, the oil pipe clip plate rack production process of the light truck-type of east wind bends twice by original operation two blanking, operation three and is optimized for present operation two blanking bending together.Single products split run production capacity is promoted to 13200 by 7300, and split run production capacity improves 80.8%.
