Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile parts stamping production, and specifically relates to a nitrogen spring pressure monitoring device. BACKGROUND

[0002] In the field of automobile stamping production, stamping dies are usually used for processing and production, and many positions in the die are provided with pressure by nitrogen springs. The nitrogen spring is a gas spring applied to the die, which mainly provides elastic force by using nitrogen as elastic medium. It can provide constant pressure, reduce friction and wear, reduce the weight of the die, improve working accuracy, simplify die design and manufacturing, facilitate installation and adjustment, prolong the service life of the die, and ensure the stability of product quality. When the pressure of the nitrogen spring is insufficient, it will cause the quality of the formed parts to decrease, and even damage the die surface. At present, the nitrogen spring pressure monitoring is mostly achieved by connecting an air pressure gauge, and the air pressure is detected by artificial irregular inspection. This method cannot timely find nitrogen spring failure, and the labor cost and maintenance cost are high. Once a failure occurs, it will cause full sequence waste products and cause downtime. SUMMARY

[0003] The technical problem to be solved by the patent is that during the stamping process of automobile parts, when the nitrogen spring fails to provide sufficient pressure, it will cause problems in the product quality of the stamped parts. The patent proposes a nitrogen spring pressure monitoring device, which can monitor the pressure of the nitrogen spring in the upper and lower dies of the automobile part stamping die in real time, and ensure that the nitrogen spring has sufficient pressure for the processing and production of the stamped parts during the stamping process.

[0004] In order to solve the above technical problems, the utility model is implemented as follows:

[0005] A nitrogen spring pressure monitoring device, comprising a nitrogen spring, a pressure sensor, a signal converter, a signal processing module and an alarm; one end of the pressure sensor is connected to the nitrogen spring, and the other end is connected to the signal converter; the signal processing module monitors the pressure of the nitrogen spring in real time through the signal converter, and can display the pressure value in real time; the signal processing module can simultaneously connect multiple pressure sensors, and set independent pressure ranges for each pipeline; when the pressure of any one path is lower than the set value, the alarm will issue an alarm; the signal processing module can also monitor the pressure of the nitrogen spring on the stamping die through the pressure sensor, to ensure that the product quality will not be affected by insufficient pressure during the processing and production of the stamping die.

[0006] The pressure sensor corresponds to a pipeline on the signal processing module, monitors the pressure of the nitrogen spring in real time, and transmits data to the signal processing module to display the pressure value in real time.

[0007] When both the upper die and the lower die need pressure monitoring, pressure sensors need to be installed respectively, but one alarm can be shared. That is, no matter how many pipelines of the upper die or the lower die need to be monitored, one alarm can be shared.

[0008] The signal processing module can monitor six pressure sensors at the same time, and an independent pressure range can be set for each pipeline. When the pressure of any one pipeline is lower than the set value, the alarm will issue an alarm.

[0009] The beneficial effects of the utility model patent are that the signal processing module is used to monitor the pressure value of the nitrogen gas spring in real time, and when the monitored pressure is lower than the set value, the alarm will issue an alarm. The device is simple to operate, convenient to use, time-saving, labor-saving and cost-saving. The nitrogen gas spring pressure monitoring device has a good auxiliary effect, can monitor the nitrogen gas spring pressure of multiple lines in real time, and helps enterprises reduce labor costs and production costs.

[0013] The preferred embodiments of the utility model will be described in detail below in combination with the drawings, so that the advantages and features of the utility model can be more convenient for the technicians in the field to understand, and the protection scope of the utility model can be more clearly and explicitly defined.

[0014] As Figure 1 It is a schematic diagram of the nitrogen gas spring pressure monitoring device. It mainly includes the nitrogen gas spring 1, the pressure sensor 2, the signal converter 3, the signal processing module 4 and the alarm 5. One end of the pressure sensor is connected to the nitrogen gas spring, and the other end is connected to the signal converter. The signal processing module monitors the pressure of the nitrogen gas spring in real time through the signal converter, and displays the pressure value on the monitor in real time. The signal processing module can connect up to six pressure sensors at the same time, and an independent pressure range can be set for each pipeline. When the pressure of any one pipeline is lower than the set value, the alarm will issue an alarm. The signal processing module monitors the pressure of the nitrogen gas spring on the stamping die in real time through the pressure sensor, ensures that the pressure meets the requirements during the processing and production of the stamping die, and thus avoids product quality problems caused by abnormal pressure.

[0015] The working principle of the device is as follows:

[0016] When both the upper and lower molds need to be monitored, pressure sensors should be installed respectively. One end of the pressure sensor is connected to the nitrogen spring of the stamping die, and the other end is connected to the signal converter. The signal processing module is connected to the signal converter, which monitors the pressure of the nitrogen spring in real time and displays the real-time pressure value on the signal processing module. Users can adjust the pressure value range on the signal processing module. During the operation of the stamping die, if the pressure on the nitrogen spring is within the set pressure value range, the die is running normally and the alarm does not sound. If the pressure on the nitrogen spring is lower than the set range, it shows an abnormality and the alarm sounds, at which time the cause needs to be checked and adjusted in time.

[0017] The above description is only proposed as the technical solution that can be implemented by the utility model, and is not used to limit the utility model. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the utility model, without departing from the technical solution of the utility model, still belongs to the scope of the technical solution of the utility model.
