Nitrogen spring with self-induction monitoring function and pressure monitoring system thereof

Abstract

The invention discloses a nitrogen spring with a self-induction monitoring function. The nitrogen spring comprises a nitrogen spring body and a self-induction assembly, wherein an inflation connectoris arranged on the nitrogen spring body, the self-induction assembly comprises an adapter, a hose, an inflation one-way valve and a wireless pressure sensor with a wireless signal transmitter, whereinone end of the adapter is connected with the inflation connector of the nitrogen spring body, the other end of the adapter is connected with one end of the hose, the other end of the hose is connected with the gas outlet end of the inflation one-way valve, and a one-way valve connector is arranged on the wireless pressure sensor and connected with the inflation end of the inflation one-way valve.The invention further provides a nitrogen spring pressure monitoring system, and the nitrogen spring pressure monitoring system comprises a signal receiving assembly and at least one nitrogen spring.According to the nitrogen spring with the self-induction monitoring function and the pressure monitoring system thereof, a pressure value and a pressure change condition of the nitrogen springs can be checked in real time, and the nitrogen springs to be damaged can be conveniently found in advance.

Description

technical field [0001] The invention relates to a nitrogen gas spring used for automobile moulds, in particular to a nitrogen gas spring with self-induction monitoring function and a pressure monitoring system thereof. Background technique [0002] Nitrogen gas springs are widely used in the automotive mold industry. If the air pressure is too low or too high, it will affect the normal use of the mold. Therefore, it is necessary to test the pressure of the nitrogen gas spring. Conventional nitrogen gas springs are not equipped with pressure gauges. In order to test their pressure, they need to be removed from the mold and tested on a special instrument. Due to the large number of nitrogen springs used on the mold, when a problem occurs, it takes a lot of time to check one by one. For the nitrogen spring installed inside the mold, it is necessary to remove the mold first, and then remove the nitrogen spring for testing. The whole process is time-consuming and laborious. If ...

Problems solved by technology

Its shortcomings are: 1) The pressure gauge is directly installed on the nitrogen gas spring through the T-shaped connector, which takes up a lot of space, so it cannot be installed on the nitrogen spring installation position of the existing mold; 2) It does not have remote real-time monitoring function , it is difficult to find faults in time during the production process; 3) For the nitrogen spring installed inside the mold, the pressure displayed by the pressure gauge cannot be checked normally
