Abstract

The invention discloses an electromagnetic pulse forming device and method for a bimetallic composite pipe fitting, and belongs to the technical field of material plasticity forming. The electromagnetic pulse forming device for the bimetallic composite pipe fitting is characterized in that two sliding mechanisms are oppositely arranged on a base; the middle portion of an insulating rod is slidablyarranged in a second metal sleeve; a coil is fixedly arranged on the insulating rod; fixing blocks are fixedly arranged on the base; sliding blocks are slidably arranged on the fixing blocks; clamping components are detachably connected with the sliding blocks; the end portion of the insulating rod is arranged between the clamping components and the sliding blocks; a support component is arrangedbetween the two sliding mechanisms; the support component is fixedly connected with the sliding mechanisms; and a first metal sleeve penetrates through the support component. According to the electromagnetic pulse forming device and method for the bimetallic composite pipe fitting, rapid and efficient forming of the bimetallic composite pipe fitting can be achieved, and the phenomena of cracks and wrinkles of inner layer metal and poor composite pipe fitting interface bonding strength s are avoided.

Description

technical field [0001] The invention relates to the technical field of material plastic forming, in particular to an electromagnetic pulse forming device and method for bimetallic composite pipe fittings. Background technique [0002] As a non-ferrous light metal structural material, aluminum alloy has the characteristics of high specific strength and specific stiffness, good thermal conductivity, and easy recycling. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. , water, organic acid, alkaline solution and oxidizing environment have good corrosion resistance, suitable for harsh medium environment under modern industrial technology. Combining aluminum alloy and other base metals to prepare bimetallic composite pipe fittings can learn from each other's strengths and complement each other's weaknesses in terms of performance, resulting in a synergistic effect, giving full play to the excellent anti-cor...
