Asymmetric heating of bending machine failure. When the temperature of the bending machine is lower than the transition point of the steel, the asymmetric heating will produce thermal stress. Therefore, the faster the heating speed is, the greater the temperature difference between the appearance and the core of the heavy-duty bending machine is, and the greater the stress is.

However, the deformation caused by inoculation after heat treatment of bending machine die is also punished greatly, so the filter of heavy bending machine is used to remove impurities in the medium, so as to shield the normal use of valve and configuration.

Before the maintenance or cleaning of the bending machine, the upper die should be aligned with the lower die, and then put down and closed until the thing is finished. Any metal will expand when heated, because the temperature of different parts of the same heavy bending machine's die during steel heating is uneven (i.e. heating asymmetry).

This will certainly lead to uneven expansion of various parts in the die steel, resulting in the formation of internal stress due to uneven heating. If you need to start or do other purposes, you should choose the manual mode, and ensure silence.

The heating asymmetry beyond the phase transition temperature will also cause the untimely layout change, not only the layout pressure. The standard of bending machine die production lies in the specification of precision and angle.

Just imagine, if the accuracy and angle of the bending machine can not be guaranteed, it is likely to lead to the whole production into the non-standard road. It will have a certain impact on the whole production process.

The so-called heavy bending machine, simply speaking, is a large bending machine, divided into manual bending machine, hydraulic bending machine and CNC bending machine. According to the key points of synchronization, hydraulic bending machine can be divided into: torque shaft synchronization, mechanical hydraulic synchronization and electro-hydraulic synchronization. According to the nature of activities, hydraulic bending machine can be divided into up mobile and down mobile.
