The flying shear straightening and cutting machine is a piece of equipment used for metal wire processing. The following introduces it from the dimensions of working principle, structural composition, characteristics, application fields, etc:
Working Principle
Straightening Principle：
Through multiple sets of straightening wheels, the metal wire is extruded and corrected, so that the bent wire is gradually straightened as it passes through the straightening wheel set.
Cutting Principle：
Using the flying shear mechanism, during the continuous feeding movement of the metal wire, the shear blade moves synchronously at the same or similar speed as the wire, and transversely shears the wire at an appropriate timing to cut it into a set length.
The structure consists of:
1.Straightening Section: Comprises multiple straightening wheels, typically made of high-strength wear-resistant materials such as cemented carbide or special alloy steel to ensure straightening efficiency and service life. The spacing and angle of the straightening wheels can be adjusted according to the diameter and material of the wire.
2.Flying Shear Cutting Section: Mainly includes shear blades, a drive unit, and a transmission mechanism. The shear blades are generally made of high-quality tool steel or alloy steel, processed through special heat treatment for good hardness and toughness. The drive unit, usually an electric motor or hydraulic motor, drives the blades via gears, chains, or belts to perform high-speed circular or reciprocating motions for rapid wire cutting.
3.Control System: Adopts a PLC (programmable logic controller) program control system, enabling precise setting of parameters like straightening speed, cutting length, and feeding length. It also features automatic operation, fault detection and early warning, alarm functions, and production quantity setting, ensuring easy operation and high automation.
Features:
1.High-Efficiency Cutting: The flying shear cutting method synchronously cuts wires without stopping the feeding process, significantly improving production efficiency compared to traditional stationary cutting methods. It is particularly suitable for high-speed continuous production lines.
2.High Cutting Precision: Through precise control systems and advanced flying shear mechanisms, high-precision cutting length control is achieved, with cutting length errors tightly controlled to meet various user requirements.
3.Surface Protection: During straightening, the straightening wheels maintain uniform contact and moderate pressure on the wire surface, preventing scratches or indentations. The sharp shear blades ensure smooth cutting surfaces without damaging the wire's surface quality.
4.Wide Application Range: Suitable for various metal wires including gold, silver, copper, iron, aluminum, nickel, titanium, tungsten, molybdenum, stainless steel, spring steel, carbon steel, and various alloys. It can also process special-shaped materials such as hexagonal, diamond, square, flat, D-shaped, and trapezoidal wires.
Application Fields:
1.Aerospace: Processes high-precision metal wire components for aerospace applications, such as engine parts and aircraft structural components.
2.Electronics & Electrical Appliances: Fabricates connecting wires, conductors, and electrode materials for electronic products, ensuring wire straightness and cutting precision to meet the production requirements of electronic components.
3.Automotive Manufacturing: Suited for metal wire processing in automotive parts production, including seatbelt steel wires, engine valve spring wires, and brake cables.
4.Medical Devices: Used in manufacturing medical devices such as surgical needle wires, dental instrument wires, and orthopedic implant wires.
