Problems solved by technology

[0004] When welding plate-shaped workpieces, the magnetic collector is equivalent to a structure formed by the combination of component one and component two; on the one hand, the increase in the number of components will reduce the magnetic collection effect of the magnetic collector; on the other hand, this When the second component is equivalent to a conductor that can guide the induced current, it cannot guarantee that the induced current can be effectively collected to the end face of the second component, so that the magnetic effect of the magnetic collector is not obvious

Abstract

The invention discloses an electromagnetic pulse forming device. The magnetic collector comprises a magnetic pulse generating part, a spiral pipe type coil, a spiral plate type coil and a magnetic collector body, wherein the spiral pipe type coil and the spiral plate type coil are arranged at the output end of the magnetic pulse generating part in parallel, the magnetic collector is connected to one of the spiral pipe type coil and the spiral plate type coil in a switchable combined mode, the magnetic collector body comprises a magnetic collection core body, the magnetic collection core body is provided with a flow guide kerf, a middle column part and an end plate part, when the magnetic collector body is switched to the combination of the middle column part and the spiral pipe type coil, the induced current can be collected to the end plate part by the flow guide kerf, when the magnetic collector body is switched to the combination of the end plate part and the spiral plate type coil, the flow guide kerf can collect the induced current to the middle column part. By means of the structural characteristics of the magnetic collector body, the forming device can be suitable for forming and processing plate-shaped and pipe-shaped workpieces only by switching the magnetic collector body between the spiral pipe type coil and the spiral plate type coil, the coils and related tool parts do not need to be replaced, the universality of the device is enhanced, and conditions are created for reducing the production cost and improving the processing efficiency.

Description

technical field [0001] The invention relates to the technical field of electromagnetic forming, in particular to a magnet collector and an electromagnetic pulse forming device. Background technique [0002] Electromagnetic pulse forming technology is a high-speed, high-energy, short-time pulse processing technology, which is widely used in the forming and processing of various workpieces such as crimping, welding, stamping, etc.; its basic principle is to use a capacitor bank to discharge the discharge coil , A transient strong magnetic field is generated due to the rapidly changing current flowing through the discharge coil, which makes the surface of the workpiece placed in it form an eddy current and deform under the action of the electromagnetic force. In this technology, the magnetic collector is a key device that is often used. [0003] At present, for the forming and processing of plate-shaped workpieces and tubular workpieces, it is usually necessary to pair a speci...
