Problems solved by technology
[0002] The new energy vehicle bumper system is generally composed of beams, energy-absorbing boxes, brackets, inner linings, etc. The vehicle bumper is located at the front end of the vehicle, and is the first contact part in a front or rear collision accident. The bars and beams evenly transfer energy to the energy-absorbing box, and absorb the energy generated in the collision through its own crushing and deformation, thereby reducing the impact stress. Large deformation, to absorb the impact energy, reduce the damage to the impact object or people, and can effectively reduce the damage to pedestrians in the event of a collision accident. The ordinary high-strength steel energy-absorbing box currently used has high rigidity and is not easy to deform. High impact damage
At the same time, the existing energy-absorbing boxes are often made by cutting technology, and the existing cutting technology produces more waste, resulting in higher processing costs, low utilization rate of raw materials, and serious waste

Embodiment 1
[0027] from Figure 1-4 It can be seen that the machining method of an aluminum alloy energy-absorbing box in this embodiment comprises the following steps:
[0028] Step 1: For the long material, convert the fixed-length angle and saw the semi-finished product into shape, from image 3 It can be seen that the use of automatic corner sawing saw table for aluminum alloy raw materials, according to plane sawing and corner 17 ° exchange cutting, can save the leftovers generated during bevel cutting, and realize the waste-free sawing method, which can effectively The utilization rate of materials is improved, and the precision requirements of product angle processing can be guaranteed at the same time;
[0029] Step 2: From Figure 4 It can be seen that after the sawing is completed, the workpiece is grasped and transferred by the six-axis robot. The gripper of the six-axis robot not only plays the role of grasping and positioning, but also has a certain role of pushing and pres...

The invention discloses a machining method of an aluminum alloy energy absorption box, and belongs to the technical field of bumper systems. The machining method comprises the steps that 1, a long material is subjected to sizing angle conversion saw cutting, and semi-finished product forming is carried out; 2, workpieces are stacked on a wood pallet in order after saw cutting; and 3, the workpieces are subjected to a stamping process, and automatic stamping forming is carried out. According to the machining method of the aluminum alloy energy absorption box, existing steel is replaced with aluminum alloy raw materials, and the shock absorption capacity and the recycling and using value of the energy absorption box are improved effectively; and the aluminum alloy long material is subjectedto sizing angle conversion saw cutting, leftover materials produced in the process of oblique angle cutting can be saved greatly, a saw cutting mode without waste materials is achieved, the usage rateof materials can be improved effectively, and meanwhile the precision requirements of product angle machining can be met.
