Description
Technical field
The utility model relates to a kind of hydraulic pressure edge pressing mould.
Background technology
Current: in the operation of irregular large-scale sheet member bending and molding, mould is placed in to upper act formula hydraulic test and utilizes act on upper act formula hydraulic test movable slider to move, the punch-die matched moulds of mould is realized the operation of irregular large-scale sheet member bending and molding.
Conventional mould pressure-pad-force is realized by a plurality of rubber slab elastic compression, on upper act formula hydraulic test movable slider, lifts and moves, and acts on rubber fixed head, and polyurethane rubber piece is gradually reduced, and realizes the pressure-pad-force to irregular large-scale sheet member bending and molding.
Because initial deformation in product flanging forming process requires pressure-pad-force higher, but the change procedure of polyurethane rubber piece pressure-pad-force is to increase gradually with mould matched moulds.Cause the little pressure-pad-force of initial mould stroke lower, so can not meet initial deformation in product flanging forming process, require pressure-pad-force high requirement.Product is moved about in bending and molding process, mold damage alignment pin, dimension overproof, there is fold and distortion in workpiece, and mould easily blocks workpiece, and percent defective is higher.Because mould continues rising matched moulds, polyurethane rubber piece increases compression pressure-pad-force and increases simultaneously, and hydraulic test uplift force is increased, power consumption, and it is higher that polyurethane rubber piece damages frequent replacement cost, and labour intensity is large.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and can overcome above-mentioned defect, pressure-pad-force simple in structure is constant adjustable, irregular large-scale sheet member bending and molding hydraulic pressure flanging forming technique.
Hydraulic pressure edge pressing mould provided by the utility model, it is characterized in that, comprise mould bases, concave template assembly is installed under mould bases, concave template assembly both sides arrange adjustment screw, flanging stripper is installed in concave template assembly, flanging stripper moves up and down in concave template assembly, and flanging stripper is connected with hydraulic cylinder, and hydraulic cylinder is a plurality of mould bases upper plate places that are fixed on, hydraulic cylinder is connected with distributor with oil pipe respectively, and distributor is connected with hydraulic system with oil pipe simultaneously; Backing plate is installed on the die shoe top of mould bases, and punch retainer is installed on backing plate top, and punch is fixed on punch retainer, and punch retainer surface is alignment pin.
Described hydraulic cylinder is three and is all arranged on mould bases upper plate place, and hydraulic cylinder is connected with flanging stripper by push rod.
Described hydraulic system comprises oil pump, and oil pump connects unloading overflow valve, and unloading overflow valve connects again overflow valve, overflow valve connecting fluid cylinder pressure.
The beneficial effect that the utility model has is: between mould bases and flanging stripper, be uniformly distributed 3 hydraulic cylinders, be provided with live hydraulic system.In bending and molding process, controlled pressure is opened unloading overflow valve automatically, hydraulic pump off-load no-load running, power consumption is little, in 3 hydraulic cylinder fall back process, overflow valve produces back pressure and forms constant blank holder force, guarantee in the compressing process of product the constant and pressure-pad-force of initial pressure-pad-force with product require adjustable, met Product Process requirement, hydraulic system is provided with safety valve F1 simultaneously.Enough thrusts are avoided the displacement of moving about of workpiece in Forging Process, avoid plane buckling deformation, constant product quality, and production efficiency improves more than 4 times.The utlity model has the features such as automaticity simple in structure is high, and pressure-pad-force is constant.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Hydraulic pressure edge pressing mould as shown in Figure 1, comprise mould bases 1, mould bases is installed concave template assembly 21 time, and concave template assembly 2 both sides arrange adjustment screw 3, concave template assembly 2 is generally spliced and is formed die by a plurality of die blade, adjusts the space of concave template assembly 2 and punch by adjustment screw 3.The interior installation flanging of concave template assembly 2 stripper 4, flanging stripper 4 moves up and down in concave template assembly, can pass through slide rail or other sliding structures.Flanging stripper 4 is connected with hydraulic cylinder 5, and hydraulic cylinder 5 is a plurality of mould bases upper plate 6 places that are fixed on, and hydraulic cylinder 5 is connected with distributor with oil pipe 7 respectively, and distributor is connected with hydraulic system 12 with oil pipe simultaneously; Backing plate 9 is installed on die shoe 8 tops of mould bases 1, and punch retainer 10 is installed on backing plate 9 tops, and backing plate 9 plays buffer protection function.Punch is fixed on punch retainer 10, and punch retainer surface is alignment pin, and alignment pin is used for fixing punch.
Hydraulic cylinder 5 be three all be arranged on mould bases upper plate 6 places, hydraulic cylinder 5 is connected with flanging stripper by push rod 11, push rod 11 is connected the piston rod of protecting hydraulic cylinder 5 with flanging stripper 4.
Described hydraulic system comprises oil pump M, and oil pump M connects unloading overflow valve F3, and unloading overflow valve F3 connects again overflow valve F2; overflow valve F2 connecting fluid cylinder pressure; safety valve F1 works the protective effect of revealing all the details, and for closing whole hydraulic system, safety valve connects unloading overflow valve F3 and overflow valve F2 simultaneously.
Die shoe is placed in to upper act formula hydraulic test, start hydraulic system oil pump M motor, see hydraulic schematic diagram (Fig. 2) hydraulic system build-up pressure≤2.5MPa, hydraulic cylinder stretches out and promotes flanging stripper 4 in lower limit at action of hydraulic force lower piston rod, each of product parts left and right is placed in punch retainer 10, alignment pin location, on upper act formula hydraulic test movable slider, lift mobile, by the matched moulds gradually of punch-die, product parts contacts with flanging stripper 13, along with continuing upper act, moves hydraulic test movable slider, flanging stripper 13 compression hydraulic cylinder piston rods are return, hydraulic system produces back pressure (overflow valve set pressure is according to the required pressure-pad-force of formed product) by overflow valve F2.Now hydraulic pump is automatically opened off-load overflow F3 under back pressure effect, hydraulic pump no-load running, and power consumption is low.Whole Workpiece shaping process, produces ridge of high pressure pressure by overflow valve F2 and carries out flanging moulding.After Workpiece shaping, hydraulic test movable slider is controlled backhaul, and ridge of high pressure pressure disappearance off-load overflow F3 closes, and liquid oil pump stretches out the decline of promotion flanging stripper to oil cylinder delivery piston bar and realizes the profiled member material returned.
