Applicable Industry:The machine is the special equipment used for angle steel punching, marking & shearing in the field of angle steel tower industry.

Product Composition:This machine is mainly composed of transverse conveyor, rotating loading system, infeed conveyor, CNC infeed carriage, punching unit, marking unit, cutting unit, unloading conveyor, as well as hydraulic, electrical and pneumatic systems etc.

Product Feature:

1. Adopt CNC technology, servo motor infeeding, with high efficiency, stable workpiece precision. Key hydraulic, pneumatic and electric parts all imported.

2. There are three sets of punch and die on each side which can install three kinds of punches with different diameters. Three sets of moulds can move altogether controlled by PLC to change the punching back mark.

3. Computer with Chinese/English interface, easy operation, and can display the drawing of workpiece. Easy programming and can directly use the program data made by lofting software. Only need to input size of workpiece, diameter of holes, back mark and quantity of workpiece when edit program.

4. CNC infeed carriage is driven by servo motor. The photoelectric encoder feeds back the information. Closed loop control to ensure high positioning precision.

5. All marking, punching and shearing in automatic completeness, all finished angles can be unloaded by pneumatic turnover device so as to lighten the working strength.

6. The control system consists of the host computer, CNC system, servo motor, PLC, external examination sensors, etc. Just input the dimension of workpiece, the processing will be created. Furthermore, the program can be stored, selected, displayed and communicated as per the workpiece No..

7. Marking unit adopts closed frame with good rigidity. Four groups of character boxes are fixed on the marking unit which can be selected by program. Marking back mark can be set at will.

8.The punching, marking and shearing cylinders are bigger; NC carriage is new type and stronger; the clamps are stronger.
