The 3-AY41-100 press is driven by a motor through a transmission mechanism to apply machining force to the workpiece. The transmission mechanism is a reduction mechanism with belt transmission and gear transmission; The working mechanism is divided into spiral mechanism, crank connecting rod mechanism, and hydraulic cylinder.
Pressure machines are divided into three categories: screw presses, crank presses, and hydraulic presses. The crank press is also known as a mechanical press.
The screw press has no fixed bottom dead point, and can perform multiple strikes to form larger die forgings, including single, continuous, and inch movements. The impact force is related to the deformation of the workpiece. When the deformation is large, the impact force is small, and when the deformation is small (such as cold striking), the impact force is large. In these aspects, it is similar to a forging hammer. But its impact force is enclosed by the frame, so it works smoothly, with much less vibration than a forging hammer, and does not require a large foundation.
The lower part of the press is equipped with forging ejection devices. The screw press has the functions of various forging machines such as forging hammers and mechanical presses, and has strong versatility. It can be used for forging, punching, deep drawing and other processes. In addition, the screw press has a simple structure and is easy to manufacture, so it is widely used.
