Characteristics of mechanical devices and power supply devices in Auto parts Processing Machine
Apr 12, 2018

When it comes to Auto parts Processing Machine systems, it consists of three parts: mechanical devices, power supply devices, and control devices. In order to meet various technical requirements, the auto parts processing equipment adopts a double-stroke rapid air pressure transmission mechanism on the pressurizing mechanism (welding tongs), and the opening degree of the welding pliers can be changed by switching the stroke control handle. With small open to meet the welding operation requirements.

 

The general state of Auto parts Processing Machine is actually the short span of the welding pliers. When the control button is switched to the “energized” position, when the handle switch is pulled, the welding clamp clamps and pressurizes. At the same time, the current is Under the control of the control system can also be completed after a welding cycle to return to the short-stroke open state.

 

The power supply device in the Auto parts Processing Machine, the main power circuit will also be composed of a resistance welding transformer, a thyristor unit, a main power switch, a welding circuit, and the like. At present, the welding equipment we use is single-phase power frequency AC resistance welding machine with power 200kVA and secondary output voltage 20V--40V. Because a variety of models are co-produced, the equipment must process high-strength steel sheets and low-carbon steel sheets. The welding gun arms must pay attention to the transmission of large mechanical forces and welding currents. It is precisely because of this that the strength, stiffness, and heat of this equipment are required. To meet certain requirements.

 

And on the power supply device for auto parts processing equipment, must have good electrical conductivity and thermal conductivity, at the same time requiring the welding clamp to adopt water cooling, so choose the welding clamp electrode arm can withstand 400kg pressure of the new welding clamp.

 

The control device in the auto parts processing equipment, this time is to pay attention to this control device is mainly used to provide signal control resistance welding machine action to connect and cut off the welding current, then control the welding current value, fault monitoring and processing. And all the process parameters on the auto parts processing machine can be set by the customer, and the processing is convenient and simple.
