Machine details:

Wear-resisting pipe welding machine is mainly composed of walking cross, roller bracket, bedside cabinet, welding chuck, welding system, control system, etc.

  • Walkcross is mainly composed of surfacing welding beam, beam lifting body, walking base, drive system, etc.
  • Crosscolumn, beam adopts the high quality rectangular pipe welding and forms, has very good rigidity, to release the stress after welding. Orbit with rectangular linear guide rail, planing, grinding, ensure the guide of high precision and its abrasion resistance, so that the machine stability was improved.
  • (Q235)base is made of high quality steel welded together, has the very good rigidity, release the stress after welding. Base by planing, grinding, to ensure the accuracy and its wear resistance, so that the stability of the whole machine was improved.
  • Drivesystem driven by servo motor and servo drive, speed stepless adjustable, servo controller with over-current, over-voltage and over torque protection. Walk in a mobile stroke limit position installation limited position switch; ensure the safety of the use of equipme
  • Welding rotator adopts lead screw structure, center distance adjustment is achieved by the hand wheel adjustment screw form, can meet demand of the cylinder with different diameter specificatio Wheel at the bottom of the seat with a hook plate, hook on the base, realize positioning. Ensure roller without deviation, make operation of the work piece stability and reliability.
  • Roller frame was welded by plate, and go through the stress relieving treatment. To ensure the strength of the base and overcome the long time use after welding stress deformation.
  • Roller adopts the natural rubber, large carrying capacity, driving ability
  • Cabinet is made of high qualified steel (Q235) welding, has very good rigidity, to deal with the stress after welding.
  • Welding power source
  • This equipment is equipped with standard Shanghai HUGONG NB-630 type gas shielded welding machine; inverter welder can be customized according to customer’s requirement. All you can use Submerged arc welding machine.
