The stamping part is an important part of the CNC punching machine, mainly composed of pressure, bearing, pressure accurate stop device, automatic clamping and chip removal device.
Lubrication, cooling and sealing of stamping parts of CNC punching equipment for automobile stamping parts fabrication equipment are several issues worthy of attention in the process of punching machine application and maintenance.
First of all, good lubrication effect can reduce the working temperature of the bearing and prolong the service life; for this reason, it should be noted in the operation and application: at low speed, use grease and oil circulating lubrication; at high speed, use oil mist and oil-air lubrication. However, when grease lubrication is used, the sealing amount of the pressure bearing is usually 10% of the bearing space volume. Do not fill it up at will, because too much grease will aggravate the pressure and heat. For oil circulation lubrication, check the pressure lubricated constant temperature oil tank every day to see if the oil volume is sufficient. If the oil volume is not enough, increase the lubricating oil in time; at the same time, pay attention to check whether the temperature range of the lubricating oil is suitable.
In order to ensure good lubrication in the fabrication of stamping parts, reduce friction and heat, and at the same time take away the heat of the pressure components, a circulating lubrication system is usually used, a hydraulic pump is used to supply oil for lubrication, and an oil temperature controller is used to control the oil in the tank. temperature. The pressure bearing of the advanced CNC punch press is lubricated by the advanced grease sealing method, and it can be used for 7 to 10 years each time the grease is added. The new lubrication and cooling method not only reduces the temperature rise of the bearing, but also reduces the temperature difference between the inner and outer rings of the bearing to ensure that the thermal deformation of the pressure is small.
