Description
Technical field
The present invention relates to bumper assembly technical fields, more specifically to a kind of machine of aluminum alloy material energy-absorption box
Processing method.
Background technique
New-energy automobile bumper assembly is generally made of crossbeam, energy-absorption box, bracket, liner etc., and bumper is located at
Automobile front end, when front or rear impact collision accident in the component that contacts first, when collision occurs, bumper beam will
Energy Transmit evenly is deformed to energy-absorption box, by the energy generated in collision by the conquassation of itself, and certain absorption is carried out, into
And bump stress is reduced, energy-absorption box is configured to flexible structure using cell compartment, moderate finite deformation is generated in collision, to absorb impact energy
Amount reduces the damage to rammer or people, can efficiently reduce injury when crashing to pedestrian, used at present general
The stiffness by itself of logical high strength steel energy-absorption box is big, is unlikely to deform, big to the injury of rammer.At the same time, existing energy-absorbing
Box is processed into often through Cutting Process, and the waste material that existing cutting technology generates is more, causes processing cost higher, former material
Expect that utilization rate is low, wasting phenomenon is more serious.
Summary of the invention

In view of the defects existing in the prior art with deficiency, the present invention provides a kind of machinings of aluminum alloy material energy-absorption box
Method, this method machining accuracy is high, cuts product plasticity and mechanical property is good, and surface quality is excellent, and utilization rate of raw materials is high.
2. technical solution
In order to achieve the above objectives, technical solution provided by the invention are as follows:
A kind of machine-tooled method of aluminum alloy material energy-absorption box of the invention, the steps include:
Step 1: the molding of scale angular transition sawing semi-finished product is carried out for long material；
Step 2: after the completion of sawing, on workpiece block pattern row pattern and wood composite pallet；
Step 3: stamping procedure, automatic press molding are carried out for workpiece；
Step 4: the punching press excision of intermediate reinforcement is carried out；
Step 5: the inclined-plane punching press excision of long side notch；
Step 6: the inclined-plane punching press excision of short side notch；
Step 7: the groove punch forming of side；
Step 8: the cleaning of cutting finished product and hand stowage packaging.
Further, according to step 1, aluminum alloy material raw material is directed to using automatic corner sawing molding buck, by plane
17 ° of exchange cuttings of sawing and corner.
Further, workpiece carries out crawl transfer by six-joint robot.
3. beneficial effect
Using technical solution provided by the invention, compared with prior art, have the following beneficial effects:
The present invention replaces existing steel by aluminium alloy stock, and the density of energy-absorption box is effectively reduced, and improves it and absorbs punching
It hits ability and recycles value, the surface of aluminium alloy will form oxidation film naturally, be not easy to get rusty, and easily keep beautiful bright and clean
Surface, while having good plastic deformation ability requirement truly accomplishes to control production cost from source, when processing, needle
The sawing of scale angular transition is carried out to the long material of aluminium alloy, the leftover pieces generated when oblique angle cutting can be substantially saved, realize no waste mine
Sawing mode can effectively improve the utilization rate of material, while also can guarantee the rigorous of angles of product processing.
Detailed description of the invention
Fig. 1 is energy-absorption box product effect figure of the invention；
Fig. 2 is effect picture on the inside of energy-absorption box of the invention；
Fig. 3 is sawing operation flow chart of the invention；
Fig. 4 is that workpiece of the invention piles up effect picture.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples:
Embodiment 1
