Only the four-column hydraulic press itself can produce high-precision and high-precision products. The size of the compressive strength is very harmful to the work of stamping dies. In cold stamping high-precision steel parts and high-sustainability In stamping production, a four-column hydraulic press with high precision and high rigidity must be used to consider the production and processing regulations and successfully manufacture high-precision parts.
Now that the four-column hydraulic machine is a kind of hydraulic machinery with general high-efficiency, the main purpose is to remove the residue on the working table before starting to avoid collision with the power switch and cause the rail slider to start suddenly and cause safety accidents, and the anti-interference is that the four-column hydraulic machine works One of the key tasks.
The first to be able to increase the distance between the disturbed power circuit or equipment of the four-column hydraulic press and the interference signal, because the impact strength is inversely proportional to the spacing square meters, so the distance between the interference signal and the disturbed power circuit is expanded as much as possible, which will greatly reduce the impact The dissemination of the hydraulic transmission system will also reduce the repair rate of the hydraulic transmission system. Especially in the harsh environment of the switching power supply, the stable switching power supply is selected to suppress the noise of the switching power supply and the influence between the switching power supply and the ground cable. An isolation transformer is connected in the CNC machine tool equipment.
In order to prevent the four-column hydraulic press and electronic components from being harmed by external magnetic fields, protective shielding measures are generally selected, and electrostatic shielding is used to eliminate the influence caused by the sub-capacitors in the power circuit; high-frequency electromagnetic field shielding is aimed at stable electromagnetic fields and high-frequency electromagnetic fields. The use of high-permeability magnet raw materials can be used to complete the shielding, and the magnetic line of induction is limited to the shielded power-down conductor with small magnetic resistance. The use of Category 5 twisted-pair can also eliminate such effects; the magnetic shielding material is based on the reflective surface or digestion and absorption The way to bear or eliminate electromagnetic induction.
The four-column hydraulic press connects its casing to the ground for grounding protection. If the four-column hydraulic press is connected to the ground, it is the system software grounding device. According to the grounding protection or system software grounding device, it can also achieve anti-interference purposes. . The filter can suppress the influence of typing and the various influences of magnetic induction on the data signal coaxial cable. Common low-pass filters and DC filters are generally installed between the switch power supply of the four-column hydraulic press and the CNC machine tool equipment.
