Electric Power Tower Iron Accessory Use CNC Punching Machine Line For Flat Steel Channel Steel

Product Introduction:

This equipment is well-suited for CNC machining on the web surface of channel steel, both flange sides of angle steel, and flat steel (with arc forming capability). It integrates marking, punching and shearing processes in one unit, featuring high machining accuracy, fast punching speed and superior production efficiency. The system adapts perfectly to both mass production of standard parts and small-batch, multi-variant production for new product development. Each working station is fitted with a button control panel to enable one-person material loading and clamping operation.

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 Unit
Consisting of conveyor chains, sprocket brackets and transmission assemblies, the chain is fitted with positioning claws to realize automatic workpiece conveying.

2. Feeding Guide
2.1 Engineered to bear and transfer workpieces in diverse specifications.2.2 Assembled from supporting rollers, guide brackets, mounting racks and other associated structural parts.

3. CNC Feed Carriage
3.1 Applied to rigidly secure raw workpieces and perform X-axis directional feeding for numerical control machining.3.2 This CNC feed carriage mainly comprises a machine frame, gear sets, hydraulic cylinders, servo motors and manipulator components.3.3 Driven by servo motor power, the carriage achieves high-precision longitudinal positioning of workpieces.

4. A-axis CNC Punching Unit
4.1 It consists of the machine frame, base assembly, transmission system, main punching hydraulic cylinder, mould switching system, working dies and pressing mechanism.4.2 A hydraulic cylinder drives the backing block to switch between different punching dies, enabling fast mould replacement.4.3 The workpiece is conveyed along the X-axis, while the punching die travels along the A-axis under servo motor drive. The mould switching system then automatically replaces punches with varying bore diameters in sequence, to finish the machining on one side of the angle steel workpiece.

5. B-axis CNC Punching Unit
5.1 It comprises the machine frame, transmission system, main punching hydraulic cylinder, mould switching system, working dies and pressing mechanism.
5.2 The workpiece is fed along the X-axis, and the punching die moves along the Y-axis powered by a servo motor. The mould switching system sequentially switches punches of different aperture sizes to complete the machining of channel steel web surfaces, one side of angle steel, and upper holes of flat steel.
5.3 A hydraulic cylinder propels the backing block to select different punching dies, ensuring efficient and rapid mould replacement.

6. Shearing Unit
6.1 Performs fixed-length cutting of workpieces to meet dimensional requirements.6.2 It is composed of the machine body, shearing dies, shearing hydraulic cylinder and other relevant components.

7. Discharge Conveyor
7.1 Designed to accommodate finished workpieces after punching and shearing processes.
7.2 It structurally comprises guide supports, carrying rollers, hydraulic cylinders and associated parts.
7.3 Upon completion of punching and shearing, workpieces are manually shifted to the unloading station, where the tilting cylinder is manually operated to realize workpiece discharge.

8. Hydraulic System
8.1 Consists of a control assembly, driving hydraulic power unit and other auxiliary components.
8.2 Control Assembly: Incorporates hydraulic elements for the regulation of each punching and shearing unit, as well as pressure safety protection devices.
8.3 Driving Hydraulic Power Unit: Mainly configured with an oil tank, motor and hydraulic pump, and fitted with a filtering device.
8.4 Cooling Mode: Adopts water cooling, with inlet water temperature controlled at ≤20°C.
8.5 Operating Pressure: High pressure rated at 25MPa

9. Pneumatic System
9.1 Mainly applied for mould selection, workpiece clamping and other related operations.
9.2 It requires the supply of dust-free and moisture-free compressed air.

10. Electrical System
10.1 Composition of Electrical Control System:This system consists of an industrial host, Programmable Logic Controller (PLC), servo drivers, detection elements, protection components and other relevant parts.
10.2 Operating Modes of Electrical Control System:The system is provided with two operational modes: manual mode and automatic mode.Under manual mode, individual movements of each mechanism can be controlled via inching operation.Under automatic mode, all classified processing actions are executed automatically in accordance with preset machining programs.

This machine is specially designed for the flexible CNC machining of structural steel profiles, covering the web plates of channel steel, two flange surfaces of angle steel, and flat steel materials, with additional capability for arc forming. It integrates multiple process functions including scribing, punching and shearing to complete full-process machining in one station. Featuring outstanding machining accuracy and operational efficiency, the equipment is applicable not only to mass batch production of standard structural parts, but also to small-batch and diversified customized production as well as prototype trial manufacturing, ensuring stable product quality and high dimensional consistency.

This equipment is principally engineered for the perforation and fixed-length cutting of angle steel profiles. Its positioning and material feeding motions are entirely powered by servo motors. It finds extensive application in industries including communication towers, photovoltaic mounting structures, warehousing and storage systems, grain silos, construction scaffolding, as well as the automotive manufacturing industry.
