Equipment Composition:

Process Flow: The feeding device transports the workpiece to the feed chute → a CNC-assisted feeding trolley with a robotic arm clamps the workpiece → workpiece end positioning → typing machine → CNC punching machines A and B punching → shearing machine shearing → manual control of the discharge chute flipping for unloading.

1. Feeding Device:
Comprised of a conveyor chain, sprocket supports, and a transmission mechanism. The chain is equipped with claws that transport the workpieces.

2. Feeding Channel:
2.1 Designed to support and convey workpieces of varying specifications.
2.2 Constructed from support rollers, channel brackets, racks, and related components.

3. CNC Feeding Trolley:
3.1 Utilized to securely clamp workpiece blanks and feed them along the X-axis for CNC processing.
3.2 The CNC feeding trolley is composed of a frame, gears, cylinders, servo motors, and a robotic arm, among other elements.
3.3 Driven by a servo motor, the CNC feeding trolley enables precise longitudinal positioning of the workpiece.

4.A-side CNC punching machine:
4.1 Composed of machine body, base, transmission mechanism, main punching hydraulic cylinder, die changing system, die, and pressure device.
4.2 A cylinder pushes a pad to select different dies for punching; die changing is rapid.
4.3 The workpiece is fed along the X-axis, and the punching die moves along the A-axis, driven by a servo motor. Then, the die changing system sequentially changes punches of different hole diameters to complete the machining of one side of the angle steel workpiece.

5.B-side CNC punching machine:
5.1 Composed of machine body, transmission mechanism, main punching hydraulic cylinder, die changing system, die, and pressure device.
5.2 The workpiece is fed along the X-axis, and the punching die moves along the Y-axis, driven by a servo motor. Then, the die changing system sequentially changes punches of different hole diameters to complete the processing of the web of channel steel, one side of angle steel, and the upper hole of flat steel.
5.3 A cylinder pushes a pad to select different dies for punching; die changing is rapid.

6.Shearing Machine:
6.1 Shears workpieces to the required length.
6.2 Consists of machine body, shearing die, and shearing cylinder, etc.

7.Discharge Channel:
7.1 The discharge channel is used to hold the workpieces after punching and shearing.
7.2 The discharge channel consists of channel support, support rollers, cylinder, etc.
7.3 After punching and shearing, the workpieces are manually pushed to the unloading position and manually controlled by the tilting cylinder for unloading.

8.Hydraulic System:
8.1 Composed of a control unit, drive hydraulic station, and other auxiliary units.
8.2 Control Unit: Includes hydraulic components controlling each punching and shearing machine, pressure safety devices, etc.
8.3 Drive Hydraulic Station: Mainly composed of an oil tank, motor, pump, etc., and equipped with a filter.
8.4 Cooling Method: Water cooling, inlet water temperature ≤20°C.
8.5 Working Pressure: High pressure 25MPa

9.Pneumatic System:
9.1 Primarily used for mold selection, clamping, etc.
9.2 Requires dust-free and water-free compressed air.

10.Electrical System:
10.1Composition of the Electrical Control System:
It includes a host computer, PLC (Programmable Logic Controller), servo drives, detection and protection components, etc.
10.2 Electrical Control System Operating Modes:
The system operates in two modes: manual and automatic.
In manual mode, the actions of each individual machine are controlled by inching.
In automatic mode, various categorized actions are automatically completed according to pre-programmed machining procedures.

This equipment is engineered for flexible CNC processing of structural steel elements, including the web surfaces of channel steel, both flanges of angle steel, and flat steel profiles, which can also be formed into curved or arched shapes. It is capable of executing a variety of operations on these materials, such as precise marking, accurate punching, and high-quality shearing, delivering comprehensive processing capabilities within a single setup. By integrating these versatile functions, the machine ensures efficient and precise fabrication of angle steel, flat steel, and channel steel components, making it well-suited for the production of custom structural parts, prototypes, and sample pieces with consistent quality and dimensional accuracy.

It is designed for punching, marking, and shearing operations on angle steel, flat steel, and channel steel. It is primarily employed for the fabrication of cross-arms, hoops, five-hole connecting plates, flat pads, and benches used in electrical power tower hardware components.
