Precision High Speed CNC Punching Marking And Shearing Line For Angles With Smart Control

Precision High Speed CNC Punching Marking And Shearing Line For Angles With Smart Control

Product Introduction:

The JNC series high-speed CNC angle steel punching, marking, and cutting production line mainly consists of core components such as a punching module, marking module, cutting module, transverse conveyor, rotary conveyor, feeding conveyor, discharging conveyor, CNC feeding carriage, hydraulic system, electrical system, and pneumatic system. This production line is specifically designed for the automated processing of angle steel in the tower manufacturing sector. Its processing workflow is regulated by numerical control technology, boasting highly user-friendly operability. It facilitates automated, high-precision, multi-type, and large-scale production operations.

Specifications:

The above parameters can be adjusted and changed according to customer's specific requirements.

Product Features:

1. The punching system is available with two or three independent punching stations, each capable of accommodating three different punch diameters. The positions of the three punching dies are automatically controlled by the CNC system to achieve flexible hole spacing adjustment. The unit supports both round-hole and slotted-hole punching operations. With high-speed material feeding and rapid punching cycles, it significantly improves production efficiency. When processing angle steel with a specification of 50 × 50 × 4 mm, the production capacity can reach approximately 9–10 tons per 8-hour shift.

2. The marking system adopts a fully enclosed structural design, providing excellent rigidity and stable operating performance. It is equipped with four sets of character cassette assemblies, which are automatically selected through CNC program control, while marking intervals can be freely adjusted according to production requirements. In addition, an optional rotary disc marking system is available. Featuring a 10-row character arrangement, the disc-type marking device enables automatic character selection without manual adjustment, greatly improving marking speed and overall production efficiency.

3. The cutting unit adopts a heavy-duty single-blade shearing mechanism featuring high cutting force and reliable shearing performance. The optimized cutting process eliminates material waste during operation while ensuring smooth, clean, and high-quality cut surfaces. The blade holder is designed with an open-access structure, allowing fast, convenient, and safe blade replacement, thereby reducing maintenance time and improving equipment availability.

4. The horizontal transfer table is designed to automatically convey angle steel materials to the rotary loading mechanism. Driven by a motor and precision reduction gearbox system, the rotary loading unit ensures accurate positioning and stable transfer of angle steel onto the feeding conveyor, providing reliable material handling throughout the production process.

5. The workpiece is firmly clamped and accurately transported by the CNC feeding carriage, ensuring excellent positioning precision and repeatability. The feeding carriage is driven by a servo motor and integrates a photoelectric encoder with a closed-loop feedback control system, enabling precise material positioning and stable automatic feeding performance.

The demonstration samples produced by the angle steel punching, cutting, and marking production line cover a wide range of standard angle steel specifications and typical processing applications used in transmission tower manufacturing. These representative workpieces allow customers, engineers, and quality inspection personnel to directly evaluate the machine’s machining accuracy, processing quality, operational stability, and overall manufacturing performance.

In Ultra-High-Voltage (UHV) transmission line construction, where transmission towers are required to withstand severe environmental conditions and substantial structural loads, this equipment plays a vital role in manufacturing the angle steel components that constitute the primary load-bearing framework of the towers. The system efficiently performs high-precision punching, cutting, and marking operations on angle steel used for tower bodies, cross-arms, and other critical structural members. By ensuring accurate dimensional control, reliable connection quality, and excellent assembly precision, the equipment contributes to improved structural strength, operational safety, and long-term service reliability of transmission towers.
