Low Cost Numerical control press

As an important equipment for metal sheet processing, the design of the transmission mechanism of low cost numerical control press directly affects the processing efficiency and accuracy. The common transmission mechanisms of numerical control press mainly include the following:

1. crank slider mechanism

Composition: The crank slider mechanism is the core component of the main transmission system of a numerical control press, usually consisting of a motor, a pulley flywheel transmission device, a clutch brake, a crankshaft, bearings, a dynamic balance mechanism, a connecting rod guide column assembly, and a slider.
Working principle: The motor drives the crankshaft to rotate through a flywheel transmission device, and the crankshaft drives the connecting rod to move, thereby causing the slider to move vertically up and down, achieving stamping of metal plates.

Features: The crank slider mechanism has a simple and compact structure, can withstand large impact forces, and moves smoothly and reliably.

2. Servo motor drive mechanism

Composition: The servo motor drive mechanism consists of a servo motor, a reducer, and a transmission pair (such as a screw, crank elbow mechanism, etc.).
Working principle: The servo motor receives instructions from the control system, reduces speed and torque through the reducer, drives the transmission pair to move, and then drives the punch for precise position and speed control.

Features: The servo motor drive mechanism has the advantages of high speed, high efficiency, high precision, and energy saving and environmental protection. It can achieve precise positioning and fast response of the punch, improve machining accuracy and production efficiency.

3. Synchronous belt drive mechanism

Application: The synchronous belt transmission mechanism is widely used in the turret and synchronous belt transmission devices of CNC turret and low cost numerical control press.
Composition: The mechanism includes a transmission shaft, small synchronous belt pulley, large synchronous belt pulley, motor synchronous belt pulley, driving synchronous belt pulley, and synchronous toothed belt.
Working principle: The motor drives the large synchronous belt pulley to rotate through the motor synchronous belt pulley, and the large synchronous belt pulley drives the small synchronous belt pulley to rotate through the synchronous toothed belt, thereby driving the turret to rotate.

Features: The synchronous belt transmission mechanism has accurate transmission ratio and high precision, which can ensure the stability and reliability of the turret during rotation.

4. Other transmission mechanisms

In addition to the common transmission mechanisms mentioned above, numerical control press may also adopt other forms of transmission mechanisms, such as chain transmission, gear transmission, etc. These transmission mechanisms each have their own characteristics and can be selected according to specific application scenarioses and needs.
In summary, there are various transmission mechanisms for low cost numerical control press, each with its unique advantages and applicable scope. In practical applications, the appropriate transmission mechanism should be selected based on factors such as processing requirements, equipment performance, and economy.
