Description
Technical Field
[0001] The utility model belongs to the technical field of pressure monitoring devices, and particularly relates to a dual-drive pressure monitoring module. Background Art
[0002] A special nitrogen spring for molds (referred to as a punching die nitrogen spring or a nitrogen spring or a nitrogen cylinder or a nitrogen tank) is a new type of elastic component with high-pressure nitrogen as the working medium. It has the advantages of small volume, large elastic force, long stroke, stable operation, precise manufacturing, long service life (one million times), gentle elastic force curve, and no need for pre-tightening, etc. It can perform tasks that are difficult to complete by conventional elastic components such as metal springs, rubber, and air cushions, simplifies the mold design and manufacturing, facilitates the mold installation and adjustment, extends the service life of the mold, ensures the stability of product quality, and can also be designed as a nitrogen spring system to participate in the work as part of the mold, and can easily achieve constant pressure and delay action in the system. It is an ideal elastic component of a new generation with flexible performance.
[0003] The nitrogen spring needs to be filled with high-pressure nitrogen inside and reach the set pressure before it can be used normally. The traditional method for filling nitrogen into the nitrogen spring is: the external gas source end inflation joint is connected to the nitrogen spring, and an air pump is used to inject high-pressure nitrogen into the nitrogen spring. To ensure that the filled nitrogen pressure meets the set requirements, pressure supplementation or pressure relief operations will be carried out. In the above process, the existing monitoring device is inconvenient to operate, and it is necessary to repeatedly install and uninstall the corresponding pipeline to make the air pressure reach the standard, which is rather cumbersome. Content of the Utility Model
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0005] A dual-drive pressure monitoring module, comprising:
[0006] A main valve body, inside which there is a main flow channel extending along the length direction of the main valve body;
[0007] An inflation nozzle, arranged on the side of the main valve body and communicated with the main flow channel;
[0008] A sub-valve body, arranged in sequence along the setting direction of the main flow channel and connected to the side of the main valve body;
[0009] A pressure relief valve, connected to the sub-valve body and communicated with the main flow channel;
[0010] Two connection valves, respectively connected to the corresponding sub-valve bodies, and the connection valves are communicated with the main flow channel; and
[0011] Pressure gauges, having the same quantity as the connection valves, for displaying and monitoring the air pressure or hydraulic pressure value of the peripherals corresponding to the connection valves.
[0012] Furthermore, a flow splitting channel communicating with the main flow channel is provided in the flow splitting valve body, and the pressure relief valve and the connection valve are communicated with the main flow channel through the flow splitting channel.
[0013] Furthermore, an inflation channel is provided in the main valve body, and the inflation nozzle is communicated with the main flow channel through the inflation channel.
[0014] Furthermore, the flow splitting valve body is located at the bottom of the main valve body.
[0015] Furthermore, a protective cover is connected to the main valve body.
[0016] Furthermore, the pressure gauge includes a mechanical pointer type pressure gauge.
[0017] Compared with the prior art, the present utility model has the following beneficial effects:
[0018] This module adopts two parts, namely the main valve body and the flow splitting valve body. The external air source can be connected to this monitoring module through the inflation nozzle. The high-pressure gas is respectively diverted to the corresponding connected connection valves through the main flow channel, and is connected to the nitrogen spring through the connection valve and the attached pipe fittings, so that two groups of devices to be inflated can be operated simultaneously to ensure the pressure balance of each path.

Therefore, the terms describing the positional relationship in the accompanying drawings are only for illustrative purposes and cannot be construed as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.
[0029] As Figure 1 - Figure 6 As shown, a dual-drive pressure monitoring module of the present utility model includes a main valve body 1, a sub-valve body 2 connected to the bottom of the main valve body 1, an inflation nozzle 3, a pressure relief valve 4, and a connection valve 5.
[0030] Among them, a main flow channel 10 extending along the length direction of the main valve body 1 is provided in the main valve body 1. The main flow channel 10 provided in the main valve body 1 circulates the external gas source in a predetermined form to realize the simultaneous filling of multiple gas paths or oil paths and ensure the pressure balance of each path.
[0031] The inflation nozzle 3 is arranged on the side of the main valve body 1 and is communicated with the main flow channel 10;
[0032] Among them, the sub-valve body 2 is arranged in sequence along the direction of the main flow channel 10 and is connected to the side of the main valve body 1;
[0033] The pressure relief valve 4 is connected to the sub-valve body 2 and is communicated with the main flow channel 10. During pressure relief, a certain pressure pipeline can be relieved of pressure separately.
[0034] Two connection valves 5 are provided, which are respectively connected to the corresponding sub-valve body 2, and the connection valve 5 is communicated with the main flow channel 10;
[0035] The pressure gauge 6 is used to display and monitor the air pressure or hydraulic pressure value of the corresponding peripheral device of the connection valve 5, and its quantity is the same as that of the connection valve 5.
[0036] This pressure monitoring module can not only monitor the pressure of the nitrogen spring pipeline system, but also be used to monitor the internal pressure of the robot balance cylinder, with wide applications.
[0037] In this embodiment, the module is divided into two parts: the main valve body 1 and the sub-valve body 2. The external air source can be connected to this monitoring module through the inflation nozzle 3. The high-pressure gas is respectively diverted to the corresponding connected connection valve 5 through the main flow channel 10, and is connected to the nitrogen spring through the connection valve 5 and the accessory pipe fittings. It can operate on two groups of devices to be filled at the same time to ensure the pressure balance of each path. When the corresponding underpressure or overpressure occurs, a certain group of devices to be filled can be operated independently without affecting the other group of devices, which is also more convenient in use.
[0038] Specifically, as Figure 3 、 Figure 4 、 Figure 5 shown, a shunt channel 20 communicating with the main flow channel 10 is provided in the sub-valve body 2, and the pressure relief valve 4 and the connection valve 5 are connected to the main flow channel 10 through the shunt channel 20.
[0039] An inflation channel 11 is provided in the main valve body 1, and the inflation nozzle 3 is connected to the main flow channel 10 through the inflation channel 11.
[0040] During inflation, the external air source is connected to this inflation nozzle 3. At this time, the gas flows through each sub-valve body 2 along with the main flow channel 10. A connector valve is installed on the sub-valve body 2, and its function is to connect or disconnect the high-pressure gas path.
[0041] When the connection valve 5 is opened, the air flow flows into the shunt channel 20, and enters the pressure gauge 6 connected to the shunt channel 20, as well as the external device to be pressure-measured / inflated.
[0042] In the use of automotive molds or home appliance molds, in order to obtain good stamping products, the better the consistency of the spring return force inside the mold and the more balanced the force, the better the forming and effect, and the consistency of the air pressure needs to be ensured. With this pressure monitoring device, during inflation, multiple groups of connection valves 5 can inflate each group of external devices at the same time, ensuring the consistency of the air pressure.
[0043] Specifically, when it is necessary to inflate a certain group of pipelines alone, only the corresponding connection valve 5 needs to be opened to inflate the group of devices.
[0044] If it is necessary to inflate other groups with different pressures, only the connection valve 5 of the original group needs to be in the closed state, and the connection valve 5 of the group to be inflated is opened for inflation.
[0045] In addition, during pressure relief or pressure regulation, the specific operation is as follows: first open the connection valve 5 of the corresponding group, and then open the total pressure relief valve 4 to relieve pressure or regulate the pressure of this group.
[0046] In addition, a protective cover 7 is connected to the main valve body 1. The protective cover 7 can play a role in safely protecting this monitoring module, preventing external impacts and causing damage to the components of the module.
[0047] Among them, the pressure gauge 6 can preferably adopt a mechanical pointer type pressure gauge. The mechanical pointer type pressure gauge has relatively low procurement and maintenance costs and strong reliability, and is suitable for high-pressure use scenarios in the range of 0 - 40 MPA. Of course, other types of pressure gauges can also be used for monitoring according to needs, such as the liquid crystal digital display form, etc.
[0048] It should be noted that this monitoring module can also be set to three-drive, four-drive or five-drive and above, and only corresponding relevant components such as the connection valve 5 need to be added.
[0049] The above are only the embodiments of the present utility model. Common knowledge such as the specific structures and characteristics known in the art are not described in detail here. Those of ordinary skill in the art know all the common technical knowledge in the technical field to which the utility model belongs before the application date or the priority date, can know all the existing technologies in this field, and have the ability to apply the conventional experimental means before this date. Those of ordinary skill in the art can, under the inspiration given in this application, combine their own abilities to improve and implement this solution. Some typical well-known structures or well-known methods should not be an obstacle for those of ordinary skill in the art to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
