  • PRODUCT OVERVIEW
  • PARAMETER
Purpose:

Forced tube expander is the key to process high quality air conditioner heat exchanger The equipment adopts multi axis numerical control technology to realize position conversion, workpiece height adjustment and expansion

It has the advantages of high degree of automation, convenient operation and good performance

Depending on the characteristics of characteristic:

1.Forced clamping at both ends of the workpiece, and then expanding the tube, the length of the workpiece will not change and there will be no shrinkage deformation, which can save 3 ~ 5% of the raw materials.

2.The rotation table is used to transpose the position, which realizes the simultaneous completion of two-stage expansion and tube expansion on one machine.

3.The tube expansion height, expansion depth and rotary table positioning are all controlled by servo motor.
