The transformer core cutting machine is mainly composed of material feeding system, cutting machine, automatic stacking and arranging system, main control panel and electrical control system.
Decoiler (Material Feeding System)
Material feeding is the initial step in the transformer core cutting machine, which is equipped with three decoilers, each capable of holding up to 5 layers of amorphous ribbons with approximately length of 1 ton. The three decoilers provide a synchronized supply of 15 layers of amorphous ribbons for cutting. Since amorphous ribbons are relatively thin, about 0.025mm per layer, using three decoilers to transport 15 layers of amorphous ribbons at once significantly improves the efficiency of cutting and stacking.
Features
- Three decoilers are configured in this amorphous core cutting line, each decoiler can be used independently or jointly.
- Each decoiler has stepless speed control.
- All three decoilers are integrally installed on the machine skid, making transportation, installation, and mobility convenient.
Cut-To-Length Shear (Cutting Machine)
The cut-to-length shear uses a low inertia servo motor for feeding, and two double-acting air cylinders are employed to execute the pressing and lifting motions of the upper feeding rollers. The air cylinder pressure is adjustable within a range of 0 to 0.7 MPa. The cutting machine head and body are designed as a detachable modular structure, making equipment maintenance convenient. The shearing section utilizes imported linear guides, a high-power servo motor with a crank-rod mechanism, and high-precision cutting tools to achieve high-precision cutting requirements.
Main Control Panel and Electrical Control System
All the functions of the transformer core cutting machine can be realized via the main control panel, which uses a PLC intelligent control system to achieve automatic material feeding, cutting, and stacking. When the main control panel is in operation, the display screen allows real-time monitoring of the system's status, thus ensuring the smooth operation of cut-to-length line. Multiple emergency stop buttons are placed along the operation and inspection path of the main control panel to ensure safety. The pneumatic actions in various parts of the machine are all controlled by the program and are adjustable.
Automatic Ribbon Stacking & Arranging System
The linear motion of our stacking table is achieved through a servo motor via a variable-speed mechanism, rack and pinion. Upon receiving a batch of materials, the stacking table can be positioned according to preset program requirements to meet different lamination requirements for amorphous cores. The stacking thickness is controlled by a pressure cylinder mechanism with limits; based on limit signals, it can automatically descend until the stacking thickness meets the core requirements. Depending on the different cutting lengths, we can provide two types of ribbon arranging mechanism: suspended type and horizontally placed type.
Features
- Our amorphous core cutting equipment is designed as an integrated unit, with the electrical control system and main modules installed inside the machine body. The operating screen is mounted on the left side of the machine using a swing arm, making it convenient for workers to operate.
- Successful development of inline weighing technology for amorphous ribbon core production line.
- The head and frame of our transformer core cutting machine are separable, facilitating disassembly for maintenance.
- The servo system, PLC, and touchscreen are from Japan Mitsubishi, with a 10.4-inch color touchscreen.
- The main pneumatic components of our amorphous core cutting equipment are from the German brand FESTO.
- The material feeding platform lifting mechanism uses high-quality ball screw guides, offering wear resistance, high load-bearing capacity, and high precision.
- The feeding system of our transformer core cutting machine ensures stable and reliable performance, ensuring the high-speed transport of amorphous ribbon materials.
- The cutting length is driven by a servo motor and controlled by a computer, enabling automatic length adjustment for cutting.
