Punch noise control technology and punch shock absorption and noise reduction scheme, Shenzhen Quelte Sound and Noise Reduction Engineering Technology Co., Ltd. specializes in punch noise control and punch shock absorption and noise reduction. Punching machines are mechanical devices that process materials by pressure and are widely used in industrial production . The punching machine relies on the flywheel, the eccentric wheel and the connecting rod mechanism to drive the punch to work up and down. The noise generated by the punch bed much higher than normal noise machine lathes, milling machines, etc., typically 9 5 ~ 1 1 0dB, even up to have 12 5 ~ 13 5 dB. The working noise of the punch mainly comes from the following four parts: 1. Because the punch of the punch presses the workpiece at a high speed, the workpiece suddenly decelerates, causing strong aerodynamic noise, which is usually called the deceleration effect. 2. The noise generated by the air ejected from the surface of the mold due to the rapid approach of the mold is called the air jet effect. 3. When the punch starts to impact the blank, the blank suddenly expands to cause impulse noise, which is called the expansion effect of the blank. 4. Punch vibration, under the impact load, the components of the punch structure are excited to generate vibration and emit noise, which is called the excitation effect of the machine structure. It can also be called excitation structure noise or solid noise. The radiation of the punch vibration is very strong, and it has a great influence on the environment, especially the lower layer. It is also the main problem of punch noise control. The noise intensity generated by each of the above four items is difficult to discern in the test results. Because they happen almost simultaneously, and to some extent are affected by machine tools, structural quality and installation. Noise control punch, a method of controlling the noise source and be cut off on the noise and vibration transmission can be used. First, the control of the noise source 1, noise control of the punch structure 2, reduce the noise of no-load and auxiliary devices 3, reduce the noise of the mold area Second, control over the path of noise propagation 1, punch shock absorption 2, reasonable layout of the punching workshop , regional separation noise In addition , measures such as sound absorption and noise reduction, sound insulation cover or sound insulation barrier noise reduction can be adopted. Punch noise control and punching shock reduction and noise reduction schemes require on-site survey of sound source and environment, and analysis, based on the analysis results combined with field conditions for the design of sound insulation and noise reduction technology.
