specific Embodiment approach 1

[0044] Specific implementation mode 1. Combination Figure 1 to Figure 10 Describe this embodiment, the method for connecting plates and pipes based on magnetic pulse forming described in this embodiment, the specific steps of the method are:

[0045] The step of punching the blank;

[0046] Step 1: Open a circular through hole in the center of the No. 2 base 12, and set up a positioning groove on the upper surface of the No. 2 base 12, install the lower molding plate 14 in the groove, and install the lower molding plate 14 in the cylindrical shape. A No. 1 insulating block 15 is installed in the structure to buffer the electromagnetic repulsion generated by the circular flat coil 16, and the circular flat coil 16 is arranged in the cylindrical structure of the No. 1 insulating block 15;

[0047] Step 2: Connect the positive and negative poles of the circular flat coil 16 to the positive and negative signal output terminals of the electromagnetic forming discharge system, and...

specific Embodiment approach 2

[0058] Embodiment 2. This embodiment is a further description of the method for connecting plates and pipes based on magnetic pulse forming described in Embodiment 1. Step 7 also includes installing one end of the telescopic rod 8 to the No. 1 base 6 through bolts. A step of.

[0059] The telescopic rod described in this embodiment realizes the transmission of the bulging coil and the transmission of the steel core bushing. The bolt cover surrounds the card slot to realize the fixation of the bulging coil and the steel core bushing at the designated position of the telescopic rod, and complete the transmission of the bulging coil during electromagnetic bulging and the transmission of the steel core bushing during electromagnetic connection.

specific Embodiment approach 3

[0060] Specific Embodiment 3. This embodiment is a further description of the method for connecting plates and pipes based on magnetic pulse forming described in Embodiment 1. Step 8 also includes turning over the slab material 17 after corrugated bulging in Step 7. The side hole is heat treated, and the sub-step of surface derusting is carried out on the overlapping area of ​​the flange hole.

[0061] The flanged hole after electromagnetic bulging described in this embodiment needs to meet a certain rigidity, so heat treatment is required to improve the strength and mechanical properties of the flanged hole. In addition, a steel mandrel is provided in the middle of the connection between the pipe fitting and the flanged hole cover to ensure that no structural instability occurs during the magnetic pulse connection.

Abstract

The invention discloses a magnetic pulse forming-based panel and pipe connection method and device, belongs to the field of metal material processing and forming and aims at solving the problems of low mold exchange efficiency and high large coil manufacturing cost in a multi-procedure processing process of a magnetic pulse forming technology. The method comprises the following steps of firstly punching a blank; then forming the flanged edge of a magnetic pulse; and finally installing a connection pipe fitting by using a magnetic pulse forming technology. Multi-procedure processing and forming are completed by using a coil, the forming process is fast and efficient, a formed workpiece is high in processing precision, free of a burr, small in resilience and free of a crack, a subsequent cleaning procedure and post-weld heat treatment are not needed, and the forming limit of the material and the processing flexibility of panel and pipe electromagnetic pulse connection are significantly improved. The magnetic pulse forming-based panel and pipe connection method and device are suitable for panel and pipe connection.

Description

technical field [0001] The invention belongs to the field of metal material processing and forming. Background technique [0002] The connection between the metal plate and the pipe structure has a wide range of applications in real life, such as the connection between the tank and the water pipe of the water supply pipe in daily life, the connection between the fuel tank and the oil pipeline in the automobile and aerospace vehicle, the connection of the aircraft operating rod, The connection between metal and non-metallic materials. Therefore, it is of great practical value to study the connection between plates and tubes. The connection between magnetic pulse forming technology and traditional plates and tubes provides a new forming method. [0003] With the advancement of science and technology, the development of lightweight engineering for automobiles and aerospace vehicles, the traditional punching, flanging, and connection technologies cannot meet the forming process...
