Technical field

The present invention relates to a kind of pipe end mould, refer more particularly to a kind of shaped device of pipe end shaping mould.

Background technology

Adopted the complicated hollow bended pipe of shape in order to guarantee its intensity and to alleviate the tare principle in the automobile chassis front and rear axle assembly, enlarging need be flattened by the bend pipe two ends lap-joint that is welded.Because of hollow pipe is difficult to control its plastic deformation in forming process; As pressing equipment carries out enlarging processing adopting; Not only a punching press is difficult to moulding; And the control problem of the plug stroke of traditional structure diel is difficult to resolve and determines, and can't satisfy production requirement, so steel pipe great majority when moulding have adopted special hydraulic press to come moulding.The special hydraulic press cost of investment is very high, and specific pressure control technology requirement is arranged, also need be correlated with specific oil-feed and oil return equipment.

Summary of the invention

Technical problem to be solved by this invention is: a kind of shaped device that carries out the pipe end shaping mould of pipe end moulding with impact style is provided.

In order to solve the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of shaped device of pipe end shaping mould; Comprise counterdie and patrix, described patrix comprises upper bolster and is arranged on the last shaping mould on the upper bolster that described counterdie comprises die shoe and is arranged on the compacted under mould on the die shoe; Die shoe shaping mould two ends up and down is respectively arranged with end and the interior consistent moulding plug of shape of finished product two ends pipe; The moulding plug is connected with power set, is provided with some oblique contract drive blocks on the described upper bolster in last shaping mould both sides, is movably set with some oblique contract sliding shoes on the described die shoe in compacted under mould both sides; Describedly go up two patrixes that shaping mould comprises the holding pad cushion block that is arranged on the upper bolster, is arranged on the patrix holding pad on the holding pad cushion block and is arranged on holding pad cushion block both sides and insert; The patrix holding pad is provided with the binder groove, and patrix is inserted and is provided with the moulding projection; Described compacted under mould comprises that the counterdie Renhe that is arranged on the die shoe is arranged on the plurality of side forming blocks on the oblique contract sliding shoe, and following die is provided with puts hopper, and the side forming blocks is provided with shaping groove.

Described oblique contract drive block both sides are provided with guide plate.

Described oblique contract drive block is respectively arranged with wearing plate with oblique contract sliding shoe surface.

Described oblique contract sliding shoe bottom is provided with the backhaul nitrogen spring.

Described power set are hydraulic cylinder.

Described die shoe is provided with some nitrogen springs.

Described upper bolster is provided with some stroke limit pieces.

Described upper bolster is provided with some guide pads.

Advantage of the present invention is: owing to adopted hydraulic cylinder to be driven into the core rod, make the motion of moulding plug to control separately, because tiltedly the contract drive block is respectively arranged with wearing plate with oblique contract sliding shoe surface, increased the service life of mould; Because tiltedly contract sliding shoe bottom is provided with the backhaul nitrogen spring, the pipeline section moulding contract sliding shoe that retreads can outwards be thrown off automatically, conveniently the taking-up material.Hollow curved tube after the precompressed can be accomplished the enlarging moulding through the shaped device compacting of pipe end shaping mould of the present invention again, and whole punching press flow process can be accomplished by common pressing equipment, has practiced thrift production cost.

The specific embodiment

Describe particular content of the present invention in detail below in conjunction with accompanying drawing and specific embodiment.

Shown in Fig. 1-3, a kind of shaped device of pipe end shaping mould comprises counterdie and patrix, and described patrix comprises upper bolster 2 and be arranged on the last shaping mould 3 on the upper bolster 2 that die shoe 1 is provided with some nitrogen springs 4 and some guide pads 5.Be provided with some oblique contract drive blocks 6 in last shaping mould 3 both sides on the upper bolster 2, tiltedly contract drive block 6 both sides are provided with guide plate 7.Described counterdie comprises die shoe 1 and is arranged on the compacted under mould 8 on the die shoe 1; Die shoe is respectively arranged with end and the interior consistent moulding plug 9 of shape of finished product two ends pipe in shaping mould 8 two ends about in the of 1; Moulding plug 9 is connected with hydraulic cylinder 10, also is provided with some stroke limit pieces 11 on the upper bolster 2.Be movably set with some oblique contract sliding shoes 12 in compacted under mould 8 both sides on the die shoe 1, tiltedly contract sliding shoe 12 bottoms are provided with backhaul nitrogen spring 13.Tiltedly contract drive block 6 is respectively arranged with wearing plate 14 with oblique contract sliding shoe 12 surfaces.

Two patrixes that last shaping mould 3 comprises the holding pad cushion block 15 that is arranged on the upper bolster 2, be arranged on the patrix holding pad 16 on the holding pad cushion block 15 and be arranged on holding pad cushion block 15 both sides insert 17; Patrix holding pad 16 is provided with binder groove 161, and patrix is inserted and 17 is provided with moulding projection 171; Described compacted under mould 8 comprises the following die that is arranged on the die shoe 1 18 and is arranged on the plurality of side forming blocks 19 on the oblique contract sliding shoe 12, and following die 18 is provided with puts hopper 181, and side forming blocks 19 is provided with shaping groove 191.

During use; To place die shoe the putting in the hopper 181 of die 18 about in the of 1 through the hollow curved tube after the prepressing device precompressed of pipe end shaping mould; Driving upper bolster 2 moves downward; Oblique contract drive block 6 on the upper bolster 2 promotes oblique contract sliding shoes 12 and is arranged on side forming blocks 19 on the oblique contract sliding shoe 12 to central motion, and insert moulding projection 171 on 17 of patrix presses down the bend pipe end and makes it produce deformation, and hydraulic cylinder 10 pushes pipe end with moulding plug 9 simultaneously; Final under the acting in conjunction of shaping groove 191 on moulding projection 171, the side forming blocks 19 and moulding plug 9, accomplish the pipe end moulding.After machining, earlier moulding plug 9 is deviate from, mentioned upper bolster 2 then, tiltedly contract drive block 6 is thrown off from oblique contract sliding shoe 12 thereupon, and tiltedly contract sliding shoe 12 to two side slips, has made things convenient for the taking-up of material under the effect of backhaul nitrogen spring 13.

Owing to having adopted hydraulic cylinder 10 to be driven into core rod 9, make the motion of moulding plug 9 to control separately, because tiltedly contract drive block 6 is respectively arranged with wearing plate 14 with oblique contract sliding shoe 12 surfaces, increased the service life of mould.

Hollow curved tube after the precompressed can be accomplished the enlarging moulding through the shaped device compacting of pipe end shaping mould of the present invention again, and whole punching press flow process can be accomplished by common pressing equipment, has practiced thrift production cost.
