Ultrasonic filter welding machine is an automatic machine, which is divided into two parts: filter paper cutting filter welding. The two processes are carried out at the same time: the feeding, cutting returning of filter paper are all completed by machine automation, which can reduce the loss of filter paper save cost; At the same time, the upper lower covers are automatically loaded, the manipulator is taken placed, the rotary table type automatic welding automatic discharging are used, which can save labor increase the production efficiency obtain high benefits for the enterprise.
Compared with traditional vibration friction welding simultaneous interpreting, ultrasonic welding has the following characteristics: fast welding is usually completed within one second. Because of the lack of flux, the risk of contamination is greatly reduced, thereby increasing the product grade.
The ultrasonic welding equipment is suitable for batch production automatic production environment; the ultrasonic system, electrical configuration control part of this machine are all original accessories, are controlled by servo motor to make the whole machine run stably; the spot welding system is composed of mechanical device, power supply device control device.
In order to meet the requirements of welding process, the pressure mechanism (welding tongs) adopts double stroke pneumatic transmission mechanism. The opening of welding tongs can be changed by switching the stroke control handle, which can be divided into large opening small opening, which meet the requirements of welding operation. When the control button is switched to the "power on" position the handle switch is buckled, the welding tongs are clamped pressurized. At the same time, the current returns to the short stroke opening state after completing a welding cycle under the control of the control system.
The main power circuit consists of resistance welding transformer, thyristor unit, main power switch welding circuit. At present, our welding equipment is a single-phase AC resistance welding machine with power of 200KVA secondary output voltage of 20V. Due to the co production of various models, the welding tongs need to weld steel plates low carbon steel plates, the arm of welding tongs needs to transfer large mechanical force welding current. Therefore, the strength, stiffness heating of welding tongs should meet the requirements, they should have good conductivity thermal conductivity. At the same time, water cooling is required for the welding tongs. Therefore, the electrode arm of the welding tongs should be able to withstand the pressure of 400kg.
