Open-type double crank precision punch | Hinge forming solution


Hinges have a wide range of applications in door leaves and are essential accessories. We often overlook their presence, but they play a significant role in providing buffering functionality for door leaf closure, reducing noise and friction.     Our customer is a local company in Turkey that specializes in door and window hardware, plastic door and window hardware, home door and window hardware, curtain walls, and fireproof door and window hardware. After conducting a company survey, they introduced Goanwin's  open-type double crank precision punch C2N series, which greatly improved production quality and speed. They have become one of the largest hinge manufacturers in Turkey, with products selling well in the Middle East and some products exported to Europe.     Hinges, also known as hinges, are mechanical devices used to connect two solids and allow them to rotate relative to each other. Hinges can be composed of movable components or foldable materials. Hinges are mainly installed on doors and windows, while hinges are more commonly installed on cabinets.   Open-type double crank precision punch C2N series • High-rigidity frame design, made of high-quality steel plate welded, shot blasted, and stress relieved to ensure stability and precision. • High-precision six-sided guide rail and reasonable transmission structure design to ensure stable and accurate stamping. • Important components such as crankshafts and gears undergo quenching, grinding, and other processing techniques to possess excellent comprehensive performance. • Equipped with a reliable clutch-brake device, dual solenoid valve, and overload protection device to ensure safe operation and personnel safety during production. • Can be equipped with frequency conversion speed regulation according to customer requirements. • Adjustable height for different mold requirements to adapt to various working needs. • Automatic concentrated oil lubrication system to ensure the normal operation of the punch. • Can be matched with various peripheral equipment to improve production efficiency. • The crankshaft adopts a cross-drive method and anti-offset load guide rail to enhance the punch’s resistance to offset loads. • Extra-large table machine, suitable for large-area thin sheet and automation progressive die production, improving work efficiency.

Goanwin High Speed Punching Machine Helps "Motor Manufacturing Industry"


The customer is an electric motor rotor iron core production company, covering an area of 10,000 square meters with a building area of 15,000 square meters. In 2020, they established a subsidiary in Haimen and regard product quality as the lifeblood of the company. They specifically purchased the Goanwin's gantry type six-column high-speed precision punch and high-quality molds made in Japan to improve product quality.   Currently, multiple Goanwin high-speed punches have been installed to closely cooperate with them to meet their production needs for spare parts and improve the performance and quality of their products.   The stable performance of the Goanwin punches has also strengthened their confidence in long-term cooperation. At the same time, this collaboration also signifies the recognition of Goanwin’s strength and technology by them.     The fixed part in the motor is called the stator, on which pairs of stationary main magnetic poles with DC excitation are installed. The rotating part (rotor) is called the armature iron core, on which the armature windings need to be installed. When energized, it generates induced electromotive force and acts as a rotating magnetic field to generate electromagnetic torque for energy conversion.   The motor core is made of silicon steel sheets, which used to be called silicon steel sheets. This material has good magnetic permeability but poor electrical conductivity. The motor generates magnetic force through coil winding and operates based on this magnetic force. However, due to the alternating magnetic field generating current in the iron core, if the iron core has strong electrical conductivity, it is equivalent to a closed short-circuit circuit and will generate heat, known as eddy currents. This is the same principle as the electromagnetic induction cooktop heating the bottom of a pot through an electromagnetic field. Therefore, in order to suppress these eddy currents, silicon steel materials with poor electrical conductivity are used, and the silicon steel sheets are used piece by piece instead of a solid core.   The delivery of the machine is no longer the end but the starting point of the service. In the future, with the continuous introduction of new technologies and comprehensive solutions, Goanwin is expected to become the provider of the best cost-effective solution.

Goanwin gantry punching machine supports the "New Energy Industry"


In recent years, with the rapid development of new energy vehicles, energy efficiency, environmental friendliness, safety, and lightweight have become the main directions for the future development of new energy vehicles.   With the increasing number of new energy vehicles in operation, the new energy vehicle industry has attracted global attention, with a particular focus on its safety and range. For electric vehicles, batteries are essential components that determine the vehicle’s performance and other aspects.   In response to the changing demand in the new energy vehicle market, our customer, as one of the main suppliers of new energy battery accessories, has taken the lead in introducing multiple Goanwin gantry closed-type double eccentric shaft precision punching machines from the D2N series. These machines are used for mass production of new energy battery positive and negative electrode sheets and other products. Compared to other brands of punching machines, Gouanwin gantry closed-type double eccentric shaft precision punching machines are equipped with a reliable off-brake device and dual solenoid valves, as well as overload protection devices. Closed-type punching machines have the characteristics of high strength, high rigidity, and high precision compared to C-type open-type punching machines.   New energy vehicle industry partners (partial)
