Abstract

The utility model discloses a die for edge cutting, hole punching, hole flanging, blanking and edge folding of a side bracket of an automobile water tank. The die comprises an upper die and a lower die, and is characterized in that the upper die is assembled in the way that male dies are arranged in a male die fixing plate and fixed with a padding plate and an upper die plate through positioning pins before being connected tightly through bolts, then a rectangular spring is mounted in a hole of the male die fixing plate, an elastic unloading plate and the male die fixing plate are connected through a joint bolt via an assembly hole of the upper die plate, and a small guide sleeve is mounted; and the lower die is assembled in the way that a female die, a punch-die and a lower die plate are positioned through a positioning pin and tightened through a hexagon socket bolt, and then a stock guide and the female die are connected through a bolt and a pin. The utility model integrates the procedures of edge cutting, hole punching, hole flanging, blanking and edge folding in to a whole, shortens the product line, reduce the labor intensity, shortens the production period and reduces the production cost, and has the advantages of wide application, high production efficiency and long service life.

Description

The side cut of radiator side supports, punching, hole flanging, blanking, flanging mould

Technical field

The utility model relates to a kind of mould, refers in particular to side cut, punching, hole flanging, blanking, the flanging mould of radiator side supports.

Background technology

At present, the get on the car demand of water tank side supports of market is bigger, and its production to be 08F sheet stamping by the thick 0.6mm of material form, and contour structures is complicated in the part.Because the material of part is thinner, the front and back of part and two ends, the left and right sides are asymmetric, and output is big, and this just requires the structural design of mould reasonable more, reliable.Traditional processing technology used blanking, towards the somersault limit, upward folded, to lower hem quadruplet mould, its precision is low, produce line length, operation is many, expenditure of time is big, the process-cycle is long, production cost is high, production efficiency is low.

Summary of the invention

The problem that the utility model has mainly solved is low to precision in the side cut of radiator side supports, punching, hole flanging, blanking, the flanging process, produce line length, labour intensity is big, the process-cycle is long, production efficiency is low and cost is high provides a kind of side cut, punching, hole flanging, blanking, flanging mould of radiator side supports.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of side cut of radiator side supports, punching, hole flanging, blanking, flanging mould comprise upper die and lower die, and described patrix is that each punch is packed in the punch retainer, behind alignment pin and backing plate, cope match-plate pattern location, are fastenedly connected with tight fixed bolt; The rectangle spring is packed in the hole of punch retainer again, from the pilot hole of cope match-plate pattern the elasticity stripper is connected with punch retainer and little guide pin bushing is installed with connecting bolt, finish the assembling of patrix, its top is die shank; Described counterdie be by alignment pin with die, punch-die and lower bolster location, fastening with hexagon socket head cap screw, again stock guide is connected with bolt, pin with die, finish the assembling of counterdie, the guide pillar that closes, guide pin bushing install mould and get final product.In described upper mould fixed plate and elasticity stripper, little guide pin bushing has been installed, has been realized of guiding and the protective effect of elasticity stripper for drift.

As preferably, the such scheme design feature is: adopt single monolateral, bilateral carrier mixing stock layout, rigidity and stability that billot is sent to have been guaranteed, convenient floating top pay-off feeding, correctly handled the annexation of workpiece bending forming and carrier, can shorten again and send step pitch to, improve stock utilization; Suppress device for discharging simultaneously in employing, used little guide pillar guide pin bushing, play discharging, binder, guide effect, guaranteed the smooth of part, overcome part four limits, make not frangibility of the little drift of Φ 2.8mm quick-changing type structure because of asymmetric laterally moving of causing; The leakage formula was in time got rid of under waste material adopted, and the carrier scrap (bridge) utilizes scrap cutter to cut off and discharges outside the mould, avoids influencing continuous punching production.

The utility model has the advantages that:

1, side cut, punching, hole flanging, blanking, flanging five processes are integrated, have shortened production line, reduced labour intensity, shortened the production cycle and reduced production cost.

2, have simple in structure, reasonable in design, complete function, dismounting is easy to maintenance.

3, practicality is wide, production efficiency is high, long service life.

4, machining accuracy height, surface quality is good, and production cost is low.

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is a support product structure schematic diagram.

Among the figure: the 1st, die shoe, the 2nd, punch-die, the 3rd, guide pillar, the 4th, stock guide, the 5th, die pad, the 6th, elasticity stripper, the 7th, the discharging screw, the 8th, rectangle punch one, 9th is hung pin, the 10th, rectangle punch two, 11st, pilot pin, the 12nd, punch retainer, the 13rd, backing plate, the 14th, little guide pillar, the 15th, little guide pin bushing, the 16th, rectangle spring TL16 * 40,17th, die shank, the 18th, straight pin, the 19th, upper bolster, the 20th, guide pillar guide pin bushing, the 21st, Φ 6.5 drifts, the 22nd, rectangle punch three, 23rd, special-shaped punch, the 24th, long crooked punch, the 25th, rectangle punch four, the 26th, correcting hole flanging punch, the 27th, Φ 2.8 drifts, the 28th, rectangle punch five, the 29th, stock supporting plate, the 30th, rectangle spring TM60 * 175,31st, big jigger pin, the 32nd, stage clip.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.

With reference to the accompanying drawings, Φ 6.5 drifts 21, rectangle punch 3 22, special-shaped punch 23, long crooked punch 24, rectangle punch 4 25, correcting hole flanging punch 26, Φ 2.8 drifts 27, rectangle punch 5 28 are respectively charged in the punch retainer 12, locate, be fastenedly connected by alignment pin, tight fixed bolt and backing plate 13, upper bolster 19; Packed in rectangle spring 16TL16 * 40 again in the hole of punch retainer 12, upper bolster 19 is connected with punch retainer 12, elasticity stripper 6 with discharging screw 7; Little guide pillar 14 and little guide pin bushing 15 are installed; Finish the assembling of patrix, its top is die shank 17.And then pass through alignment pin, fastening bolt with punch-die 2 and die shoe 1 location, fastening; Location, installation stock guide 4, stock supporting plate 29 are finished the assembling of counterdie on punch-die 2.Close guide pillar 3, guide pillar guide pin bushing 20 are promptly finished the assembling of mould.

During work, coiled strip is sent into from the left side after automatic feeding uncoiling, smoothing; The feeding step pitch guarantees that by side edge and pilot pin side edge is made coarse positioning, and pilot pin is made fine positioning; Four alignment pins float off the punch-die working face with billot, and are unimpeded to guarantee feeding.
