TECHNICAL PROPOSAL

(i)Main Performance Characteristics

1.   Machine Performance

The Smart series is a flexible and intelligent panel bender machine designed and produced according to high-precision machine tool standards.  It is made of high-specification castings, and both the cast and welded parts are subjected to strict stress relief processing. High-precision machine tools are used for integrated processing, ensuring long- term accuracy, stability, and high rigidity during operation.

2. Axis Configuration Description

The machine is equipped with a total of 8 axes, including 3 axes for the bending main body (X, Y and Z  axes), and  3 axes for the feeding mechanism (translation, pallet lifting, and pallet rotation). The plate positioning part includes 2 axes for positioning and part blocking.

3. CNC Control System

(II)Main Bending Process

1. Bending Process Description

Bending Process Requirements:

1 . The surface of the material to be bent cannot have downward protrusions, as this may cause

interference with the workbench and prevent automatic bending.

2.  For  suction  cup  bending  centers,  when  bending  all  four  sides  of the  material, there should  not be large  openings  in  the  center  of the  material,  as  this  will  prevent  the  suction cups  from  holding  the material  in  the  center.  For  pressing  rod  bending  centers,  there should  be  a space  reserved  for pressing  the  material .

3.  . The distance from the edge of the hole to the bending edge should be ≥ 5mm . Otherwise, there may

be a pulling effect after bending (the larger the thickness of the material, the larger this dimension should

be).

4.  . After  forming,  the  bending  direction  can  only  be  bent  in  one  direction, ultimately  facing downward.

5.  . Whether  the  bending  center  can  bend  automatically  depends  on  the  bending process  and  sequence  of the  part.  The  final  decision  will  be  based  on  the approved  drawing .

6.  . The  dimensions  of the  bending  tools  in  the  figure  on  the  right  are  standard, and  can  be  customized  according  to  customer  requirements .

7.  . The  figure  above  shows  some  examples  of upper  and    lower  bending .  The    actual dimensions

will be based  on the  size  of the product.

2. Basic Bending Dimension Requirements for Some Parts

3. Diagram of partial reverse direction bending requirements

4. Requirements for the use of partial hinge knives

5. Special bending processes

Note:  Special  bending  processes  may  result  in  inconsistent  deformation  compared  to  regular bending processes.  It  is  necessary  to verify  whether  the  actual  process  can  meet  the product requirements.
