AI Technical Summary

Technical Problem

The noise problem caused by gas pressure changes during operation of existing aluminum profile cylinders has not been effectively solved.

Method used

A low-noise aluminum profile cylinder was designed, which adopts a cylinder body, sealing cover, piston and shaft structure. Multiple sound insulation chambers and air guide chambers are set on the sealing cover. The air passage is connected to the sound insulation chamber through the air pipe. Sound guide holes and sound insulation cotton are set in the sound insulation chamber. Noise is eliminated through multiple sound insulation cotton and sound guide holes.

Benefits of technology

It effectively reduces the noise during cylinder operation. Through the design of the sound insulation cavity and sound guide hole, the gas noise consumes energy in the sound insulation cavity until it is eliminated, thus achieving low-noise operation.

Abstract

The application provides a low-noise aluminum profile and an air cylinder using the same, and relates to the technical field of aluminum air cylinders.The air cylinder comprises a cylinder body, sealing covers, a piston and a shaft body.The two ends of the cylinder body are sealed by the sealing covers, the piston is located in the cylinder body and separates the cylinder body into two chambers, the shaft body penetrates one of the sealing covers and is connected with the piston, air passages are formed in the sealing covers and communicate with the chambers, a plurality of sound insulation cavities and air guide cavities are arranged on the sealing covers, the air guide cavities are communicated by air pipes which pass through the sound insulation cavities, sound guide holes are formed in the positions of the air pipes passing through the sound insulation cavities, and the sound insulation cavities have sound guide holes on only one air pipe.In the application, when air passes through the air guide cavities, the pressure of the air is released, and the noise in the air is guided into the sound insulation cotton, is isolated by a plurality of sound insulation cottons and a plurality of air holes, and does not flow back in the sound insulation cavities, so that the noise in the air is reduced by being retained or offset through the sound guide holes into the sound insulation cavities.
