Detailed description of the invention

Below in conjunction with specific embodiment, the utility model is described further.

Embodiment 1

As shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, a kind of fender front and the synchronous hemmer in side, comprise upper bolster 10 and die shoe, die shoe is provided with counterdie punch benevolence 7, upper bolster 10 is provided with patrix material pressing core 8, also comprises positive hemmer and side flanging device; Side flanging device quantity is two covers, is separately positioned on the both sides of positive hemmer; Positive hemmer comprises positive flange cutter block 1; Positive flange cutter block 1 is connected with upper bolster 10 by two breaker bolts 9; Two nitrogen springs 2 are provided with between positive flange cutter block 1 and upper bolster 10; Side flanging device comprises side drive block 3, sideslip motion block 4, side flanging cutter block 5 and side slide base 6; Side drive block 3 is connected with upper bolster 10; Side slide base 6 is connected with die shoe; It is with respect to the horizontal plane the driving inclined-plane of 30 ° of acute angles that side drive block 3 lower end is provided with; It is with respect to the horizontal plane the intermediate incline at 150 ° of obtuse angles that side slide base 6 upper end is provided with; Driving inclined-plane, intermediate incline are provided with orbital groove; Sideslip motion block 4 one end is wedge shape, and this wedge angle is 60 °, and the both sides of this wedge shape end are equipped with the track projection corresponding to orbital groove; Sideslip motion block 4 is that one end of wedge shape is arranged between driving inclined-plane and intermediate incline, and orbital groove and track projection fasten; The other end of sideslip motion block 4 is provided with side flanging cutter block 5; The length of two side flanging cutter blocks 5 in two cover side flanging devices is respectively 300mm and 320mm.

The present embodiment combination is carried out flange processing to the structure of a kind of fender as depicted in figs. 1 and 2 and is described further, Fig. 1 is the shape before the processing of this fender flange, Fig. 2 is the shape after the processing of this fender flange, as can be seen from Figure 2, this fender positive flange position A needs first to carry out flange processing, after machining shape required for formation, two flanging side face position B and C just can process, and the flange direction of B with C is now vertical with positive flange direction, adopt the vertical flange mode same with positive hemmer, the flange poor quality obtained, so need the flange processing adopting horizontal direction.

Be placed on by workpiece to be processed as shown in Figure 1 in the counterdie punch benevolence 7 of the utility model die shoe, start upper bolster 10, upper bolster 10 declines, and close to die shoe, and first patrix material pressing core 8 contacts workpiece to be processed, and workpiece to be processed is compressed, fixing; Upper bolster 10 continues to decline, and positive flange cutter block 1 starts to contact workpiece, and carries out positive flange processing to workpiece, and after the positive flange of workpiece machines, positive flange cutter block 1 no longer declines; Upper bolster 10 continues to decline, now nitrogen spring 2 forced compression, side drive block 3 continues to decline, after Wedge mechanism commutation, sideslip motion block 4 moves in the horizontal direction between driving inclined-plane and intermediate incline, because side flanging cutter block 5 length is unequal, length is that the side flanging cutter block 5 of 320mm first carries out flange to turn-up portion position, side C, length is that the side flanging cutter block 5 of 300mm carries out flange to turn-up portion position, side B more subsequently, after flange puts in place, upper bolster 10 rises, each member reset, take off the workpiece completing flange, machine.The utility model carries out the flange processing of front and side to fender, complete in same procedure, efficiency is high, precision is high, quality is high, and in same procedure, the flange of front, two sides can realize again carrying out step by step, remains the advantage that fender divides a few procedure flange to process, turn improves operating efficiency.
