Second, the presence of the drive pressure can cause damage to some softer parts, such as by directly bending and collapsing the aluminum, magnesium, etc. alloy parts, thereby preventing the process from proceeding.
Thirdly, due to the existence of transmission pressure and a mechanical sliding mechanism assembling gap, the two columnar rods can generate different degrees of deviation towards the non-axial direction after clamping the part, and further a V-shaped gap is formed at the contact part of the columnar rods and the part, so that the part and the columnar rods are not in sufficient contact, and current does not uniformly pass through the part in the electromagnetic field treatment process, thereby influencing the treatment effect; meanwhile, due to the fact that the resistance of the local contact part is too large, local burning of the part and even damage of the part are usually caused when current passes through the part.
In addition, the part is clamped by the two columnar metal rods, and the part does not always remain in the center of a magnetic field excited by the electromagnetic processing equipment in the repeated clamping process of the part due to the fact that the part is not provided with a positioning device, and the effect of electromagnetic processing is influenced.
