Problems solved by technology

At the gap, the direction of the induced current of the two parallel surfaces is opposite, so that the two parallel surfaces repel each other. If it is used for a long time, the gap will be flared, making the center hole become an irregular circle, and the service life is low.

Embodiment 1

[0013] Example 1, such as figure 2 As shown: the open-close magnetic collector for electromagnetic pulse welding of the present invention is composed of a magnetic collector body 1, a recessed part 2, and a central hole 3. The magnetic collector body 1 is formed by butting two semi-cylindrical bodies, that is to say, the magnetic collector body 1 A cylinder is cut into two half cylinders along its axis line, and then the two half cylinders are butted to form a cylinder, and there is a gap at the joint of the two half cylinders. The magnetic collector body 1 is made of copper alloy material. The magnetic collector body 1 is provided with a central hole 3 along its axis, and the two ends of the magnetic collector body 1 are provided with a recessed part 2 which is depressed toward the center. The diameter of the recessed part 2 is larger than the aperture of the central hole 3. The end of the conical depression gradually decreases toward the center, and the diameter of the sma...

Abstract

The invention discloses an open-close magnetic collector for electromagnetic pulse welding. The open-close magnetic collector comprises a magnetic collector body (1). The open-close magnetic collector is characterized in that the magnetic collector body (1) is composed of two half cylinders in a butt joint mode, concave parts (2) are symmetrically arranged at the two ends of the magnetic collector body (1), a center hole (3) is formed in the magnetic collector body (1) along the axial line of the magnetic collector body, the opening diameter of the concave parts (2) is greater than the hole diameter of the center hole (3), and the central line of the center hole (3), the axial line of the concave parts (2) formed at two ends and the axial line of the magnetic collector body (1) are in the same straight line. The open-close magnetic collector can collect magnetic field energy better, compared with existing magnetic collectors, the magnetic field utilization ratio is increased, the service life of the magnetic collector is prolonged obviously, and accordingly the utilization cost of the equipment is lowered.

Description

technical field [0001] The invention relates to an electromagnetic pulse welding device, in particular to an opening and closing magnet collector for the electromagnetic pulse welding device. Background technique [0002] The electromagnetic pulse welding device mainly energizes the coil, then generates a strong magnetic field through the coil, and at the same time generates an induced current on the surface of the welded pipe fittings. The induced current generates a huge electromagnetic force under the action of the strong magnetic field, and then acts on the external welded pipe fittings to make The generation of radial deformation is integrated with the high-speed collision of the internal parts to be welded. [0003] The existing magnetic collector includes a magnetic collector body, the magnetic collector body is columnar, and its two ends are recessed inward to form a concave part. Through the through hole (central hole), the axis line of the concave part coincides w...
