The invention discloses magnetic forming equipment for preparing an electromagnetic shielding sealing strip. The equipment comprises an electric control cabinet, a case, a semi-closed magnet yoke, a conductive coil and a height adjusting assembly, a bridge rectifier, a transformer, a touch screen, an ampere meter, a silicon controlled rectifier and a PLC (Programmable Logic Controller) are arranged in the electric control cabinet, the case semi-covers the semi-closed magnet yoke, the whole semi-closed magnet yoke is approximately C-shaped, and comprises an upper magnet yoke, a lower magnet yoke and a connecting magnet yoke, the upper magnet yoke, the lower magnet yoke and the connecting magnet yoke are horizontally arranged, and the height adjusting assembly comprises a positioning frame, a guide rod and guide sleeve assembly, a screw rod and screw sleeve assembly and a distance adjusting plate movably connected with the lower end of a screw rod. The magnetic forming equipment can pull ferromagnetic conductive particles by controlling the magnetic flux intensity of a magnetic field by means of the current size, and regulating current parameters and magnet yoke distance parameters, and after multiple sets of sampling training are carried out, mathematical modeling and simulation are carried out through a linear regression model, so electric control parameters can be rapidly obtained, and the electromagnetic shielding sealing strip which is close to the shape of a triangle or close to the shape of n is obtained according to current intensity changes, and the applicability is wide.
Description
technical field [0001] The invention relates to the technical field of production of electromagnetic shielding sealing strips, in particular to a magnetic forming device for preparing electromagnetic shielding sealing strips. Background technique [0002] Electromagnetic shielding sealing strips or electromagnetic shielding gaskets, as sealing materials and electromagnetic shielding materials for electronic products, have been widely recognized by the market. The sealing strip is mostly made of silica gel, and the sealing strip is doped with tiny particles or flaky ferromagnetic conductive particles, and the magnetization effect of the magnetic field is used to make the ferromagnetic conductive particles obtain a magnetization effect, causing all ferromagnetic conductive particles to generate weak Magnetic poles, and then two adjacent ferromagnetic conductive particles with different poles attract each other, and all ferromagnetic conductive particles are positioned accordin...
