Description
Technical field
The present invention relates to a kind of on energy-absorbing box of automobile anti-collision rod the device of punching press guiding groove, belong to the metal stamping technical field.
Background technology
Energy-absorbing box of automobile anti-collision rod is the part of bumper, and it provides support on the one hand, and bumper is fixed on the car body, and when automobile was subjected to clashing into, energy-absorbing box of automobile anti-collision rod produced crumple on the other hand, to absorb the energy that bump is produced.Fig. 1 is that a kind of cross section commonly used is the energy-absorbing box with near closed hollow ring structure of " day " font, its wall is furnished with the indent guiding groove that high and low position differs, be used to reduce the intensity of guiding groove position, when making the energy-absorbing box produce crumple, can take the lead in according to the route of predetermined design beginning crumple from guiding groove.
Design has the guiding groove of varying number on the wall of energy-absorbing box, when adopting existing decompressor to process guide grooves of energy-absorbing box, a punching press can only be gone out a guiding groove on the wall, and process guiding grooves all on four walls then must configuration quadruplet punching press frock and punching press four times at least.In punching course, the energy-absorbing box need load and unload and stretch repeatedly, yielding, the scuffing of energy-absorbing box, and the technological operation turnaround time is long, and it is low to have reduced working (machining) efficiency, has improved processing cost.In addition, another insurmountable technological problems is, core is necessary for the material returned and abdicates the space of at least one guiding groove degree of depth, therefore core can only be done thinly, and when three faces all needed to dodge guiding groove, the thickness of core and width maximum can only be accomplished about 1/2 of energy-absorbing box inner cavity size, and, core generally adopts cantilever beam structures, and very easily in the fracture of the place of guiding groove moulding, intensity can't guarantee such core.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of dependable performance, the punch forming device of guide grooves of energy-absorbing box of automobile anti-collision rod that working (machining) efficiency is high.
Problem of the present invention realizes with following technical proposals:
A kind of punch forming device of guide grooves of energy-absorbing box of automobile anti-collision rod, it comprises core, core oil cylinder, punching press oil cylinder, the cavity shape of the profile of described core and energy-absorbing box is complementary, combine by two parts up and down, be respectively to be positioned at following quiet core and to be positioned at top moving core, two-part up and down interface is a folding face, and it is divided equally into upper and lower two parts with the die of corresponding each guiding groove; Described core oil cylinder is positioned at the top of core, and its piston rod drives moving core, and described punching press oil cylinder is provided with four, the guiding groove at respectively corresponding energy-absorbing box four sides, punch die that is complementary with corresponding guiding groove of each punching press hydraulic oil cylinder driving.
Above-mentioned punch forming device of guide grooves of energy-absorbing box of automobile anti-collision rod is provided with the positioning boss and the detent of mutual coupling on quiet core and moving core.
Above-mentioned punch forming device of guide grooves of energy-absorbing box of automobile anti-collision rod, the punching press oil cylinder that is positioned at the relative both sides of core connects same oil circuit.
Above-mentioned punch forming device of guide grooves of energy-absorbing box of automobile anti-collision rod, described core oil cylinder piston stroke is greater than energy-absorbing box height.
Core of the present invention has adopted split-type structural, core is divided into two parts by each guiding groove being divided equally into upper and lower two-part folding face, moving core and quiet core, not only solved the modulus problem that moves back after the punching press well, and all guiding grooves can by four punching press oil cylinders one time punching molded, improved operating efficiency greatly.Simultaneously, because core can be done the same with energy-absorbing box inner chamber big or smallly, its intensity also can increase greatly.Mutually chimeric positioning boss and detent is set on quiet core and moving core, and purpose is to make core and the alignment of quiet core and support mutually, and core misplaces when preventing that punch die is pressed into.The punching press oil cylinder that is positioned at the relative both sides of core connects same oil circuit, and the pressure unanimity that the core both sides are subjected to guarantees that the both sides punch die is synchronous, avoids damaging core because of unbalance loading.Core oil cylinder piston stroke is greater than energy-absorbing box height, and the spacing when core is separated with quiet core is enough big, satisfies the requirement of loading and unloading energy-absorbing box.Compare with traditional decompressor, core of the present invention has higher intensity and reliability, and simple to operate, and high efficiency has not only guaranteed energy-absorbing box quality, but also reduced production cost.

Each label is among the figure: 1, reinforcement; 2, guiding groove; 3, core oil cylinder; 4, moving core; 5, quiet core; 6, energy-absorbing box; 7, punching press oil cylinder; 8, punch die; 9, stamping cavity die; 10, positioning boss; 11, detent; 12, slide block.
The specific embodiment
Referring to Fig. 1～Fig. 2, this device comprises core, core oil cylinder 3 and punching press oil cylinder 7, divides the core of body structure to provide possibility for guide grooves of energy-absorbing box of automobile anti-collision rod 2 one-shot formings.In this device, around punch die 8 is arranged in, corresponding one by one with the guiding groove 2 of energy-absorbing box 6 each face.Punch die 8 is installed on the slide block 12, and is reciprocating under the driving of punching press oil cylinder 7.The strength that punch die 8 is pressed into is very big, can reach tens ton forces even higher, so punch die 8 must prevent that the core folk prescription is to stressed when being pressed into.This device makes the punching press oil cylinder 7 that is positioned at the relative both sides of core connect same oil circuit, and the pressure unanimity that its both sides are subjected to can guarantee that both sides punch die 8 is synchronous, has avoided unbalance loading.
Referring to Fig. 3～Fig. 4, this device has adopted a kind of core of split type and concavo-convex mosaic texture.The core profile is consistent with energy-absorbing box 6 inner chambers, and indeformable and easy to loading and unloading for energy-absorbing box 6 after guaranteeing punch forming, core and energy-absorbing box 6 inner chambers are reserved appropriate gap.Core is divided into two parts up and down, and the latter half is quiet core 5, is fixed on the support; The first half is moving core 4, is driven by core oil cylinder 3.
Moving core 4 and quiet core 5 have adopted concavo-convex structure of inlaying, and are guaranteeing that core has under the prerequisite of sufficient intensity, and solid section has been made concaveconvex structure in the central, makes positioning boss 10 on the promptly quiet core 5, and moving core is made detent 11 4 times, and vice versa.
The course of work of this device is: moving core 4 is entrenched togather with quiet core 5 under core oil cylinder 3 drives, and then, the punch die 8 of both sides is synchronized with the movement under the oil circuit control of uniform pressure, until with guiding groove 2 extrusion modlings.Afterwards, the punch die 8 of both sides repeats this process in addition.At last, moving core 4, punch die 8 return, and take out energy-absorbing box 6, and punching course finishes.
