Abstract

The invention relates to a device and method for improving die attaching performance of an electromagnetic formed workpiece. One or more magnetism collector devices are additionally arranged at the outer portion of a drive coil; and under the situation that a coil structure is not changed, magnetism collectors are used for transmitting coil energy to an area where approaching workpiece die attaching is difficult, distribution of electromagnetic force is changed, electromagnetic force in the area where die attaching is difficult is increased, seamless die attaching can be achieved for the metal workpiece, and the forming precision is improved. On the other hand, under the situation that the coil is not replaced, forming of different workpieces is achieved by replacing the different magnetism collector devices, and the flexibility of the device can be greatly improved. Due to the fact that the magnetism collectors are simple in structure, the machining period is short, the material is generally the most common copper, and the price is relatively low; and compared with coil replacement, magnetism collector replacement is more flexible, and cost is lower.

Description

technical field [0001] The invention belongs to the field of metal forming and manufacturing, and in particular relates to a device and method for improving the mold sticking property of electromagnetic forming workpieces. Background technique [0002] Lightweight is an important means and technical approach for energy saving and emission reduction in aerospace, aviation, automobile and other industrial manufacturing fields. One of the main ways to achieve lightweight is to use high-performance lightweight alloy materials, such as aluminum alloys and magnesium alloys. However, the traditional forming process has a bottleneck for forming light alloys. Due to the poor formability of light alloy materials at room temperature, it is difficult for industrial manufacturing requirements. Electromagnetic forming is one of the most potential technical means to solve the difficulty of light alloy forming. Electromagnetic forming is a high-speed pulse forming technology. The high stra...
