The use and working principle of the press

With the rapid development of science and technology, more and more machines have been manufactured. Many people have never heard of presses. Presses often appear in industries such as automobiles, home appliances, and electronics. So what is it used for and what is its working principle? Let's follow the introduction of Shanghai WORLD Press Machine to show you. The working principle of the press and the scope of application:

1. Use of the press

Presses are widely used in the forging of parts in the fields of machinery, automobiles, hardware, coal machinery, and aerospace. They are used to complete die forging, precision forging, trimming, calibration and other processes. They are widely used forging equipment. Performance is of great significance across the ages.

2. Working principle

The two main motors drive the flywheel, and the main screw drives the working slider to move up and down. After the start signal is input, the motor drives the working slider to accelerate down through the pinion and large gear from a static state. When the motor reaches the preset speed of striking energy requirements, Using the energy stored in the large gear to do work, the forging die workpiece is formed. After the big gear releases the energy, the motor also starts and drives the large gear to reverse while the working slider is rebounded by force, so that the working slider quickly returns to the preset stroke position and automatically enters the braking state.

Since the sliding block rebounds due to the impact of the reaction force in the return stroke, at this time, the output frequency of the motor only needs about 10% to make the working block return to its original position quickly, so the return stroke loss is very small. Since the working slider is braked by the motor during the return stroke, the mechanical brake only works when the slider is close to the top dead center, and the braking material is not easy to wear and does not need to be replaced frequently.

With the use of presses, the production efficiency of parts in many industries such as automobiles, home appliances, etc. has been continuously improved. It is so remarkable.
