200KN Servo control system Friction welding machine

Ⅰ. Main technical characteristics description of MCH-20SJ friction welding machine 

MCH-20SJ (maximum forging force 200KN, servo monitor) type friction welding machine produce by Shanghai Shengchun Machinery Co.,Ltd. Based on our advantages, through digestion and absorption of international advanced technology, self-developed new products. The product inherits the traditional friction welder high strength, stability, and other advantages, based on the introduction of international advanced design concepts and the use of electric proportional servo-spindle drive system and hydraulic control system. By servo spindle drive system, the spindle speed can reach up to 2500 r/min, the use of high-speed welding, effective control of the thermal diffusion zone welding parts. Closed-loop control by controlling the electric proportional hydraulic system enables all cylinders working, welding parts of the stability of a reliable guarantee. While using the welding parameters storage function in the production process, we only need to call up the corresponding product specifications to automatically match the welding parameters, reducing the operator to adjust the parameters of the process. Thus avoiding inaccuracies due to manual adjustments arising, greatly reducing the waste generation rate, the model compared to the same general type friction welding machine power consumption can be reduced by more than 40%.

The main structure

The machine consists of head stock, slide, master cylinder, rotary fixture, moving the fixture, fixture composed of tanks, bed, hydraulic system, electric control system, operator panel and other components.

Bed, Head stock

Bed and head stock are made of welded steel material, tempered sandblasted.

Bed ribs arranged inside the body, so thick bed structure. Guide the use of heavy-duty roller linear guide deputy structure, so that the machine to obtain a high rigidity and long-term stability of precision. Reciprocating motion slide along the linear guide, induced by the magnetic displacement sensor detects the motion displacement of the closed-loop and set the amount of melted welding, weld length to ensure consistency.

Spindle power system uses servo motor drive system, it can be a variety of welding the welding speed depending on the diameter of the election.

Clamp

Rotating jig for holding the U-shaped member, using collet chuck clamping.

Mobile jig using self-centering hydraulic clamp for holding a long tube member.

Hydraulic System

Friction welding machine hydraulic system hydraulic system features include forward and back through the master cylinder control slide, the clamping fixture release. The system uses electronic proportional valve technology integrated installation. Pressure and flow using electric proportional valve closed-loop control parameters can be adjusted via the HMI, and save multiple sets of welding parameters. Ensure the reliability of the whole movement, easy maintenance.
