[0001] The present application belongs to the technical field of pressure monitoring, and more specifically, to a nitrogen spring pressure monitoring device, a monitoring method and a processing equipment. Background Art

[0002] A nitrogen spring is an elastic element that converts compression displacement into output force under the action of nitrogen by utilizing the compressibility of nitrogen. Nitrogen springs have a wide range of applications due to their stable performance, long service life, small footprint, and no noise, especially in the field of automated processing equipment.

[0003] During the processing of parts by processing equipment, if nitrogen springs leak nitrogen or have insufficient pressure, it is easy to cause equipment damage and abnormal quality of processed parts. For example, most of the sliding mechanisms such as some side trimming mechanisms, side flanging mechanisms, side shaping mechanisms or pressing mechanisms of stamping dies currently use nitrogen springs as pressure sources or to provide return force. During the processing, such sliding mechanisms must perform a fixed reciprocating sliding action each time under the pressure of the press and the action of the nitrogen spring. If the nitrogen spring has insufficient pressure or is damaged during this action, the entire reciprocating action of the sliding mechanism may not be achieved according to the action or force requirements specified in the design, thereby damaging the sliding mechanism and its surrounding parts.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0040] See also Figure 1 Now, the nitrogen spring pressure monitoring device provided in the embodiment of the present application is described. The nitrogen spring pressure monitoring device can be applied to all molds with sliding mechanisms driven by nitrogen springs.

[0041] For example, a nitrogen spring pressure monitoring device includes a pressure monitoring component and a collector; the pressure monitoring component is electrically connected to the collector through a transmission line, and the pressure monitoring component is connected to a nitrogen spring located inside the mold shell through a pipeline, and the nitrogen spring is used to drive a sliding mechanism located inside the mold shell to move from a first state to a second state.

[0042] The pressure monitoring component is used to monitor the pressure data of the nitrogen spring and to transmit the pressure data to the collector, and the pressure data is used to reflect whether the nitrogen spring pushes the sliding mechanism to the second state.

[0043] The collector is electrically connected to the press through a transmission line. The collector is used to receive pressure data from the pressure monitoring component and to trigger the press to perform corresponding operations according to the pressure data.

[0044] It should be noted that the collector is electrically connected to the press through a transmission line, which means that the collector is electrically connected to the controller of the press through a transmission line. The collector is used to trigger the controller of the press according to the pressure data to control the press to perform corresponding operations. It can be understood that in the embodiment of the present application, the controller of the press can be updated with a program, for example, the original reserved 27th pin signal in the press program is updated to a nitrogen spring pressure monitoring signal, and the program logic is changed to shutdown, alarm shutdown or alarm non-stop operation according to functional requirements.

[0045] The nitrogen spring and the press are used to drive the sliding mechanism in the mold to move. Specifically, the nitrogen spring is used to drive the sliding mechanism inside the mold shell to move from the first state to the second state, and the press is used to drive the sliding mechanism inside the mold shell to move from the second state to the first state. In this embodiment, the first state may refer to the sliding mechanism being in the in-place state, and the second state may refer to the sliding mechanism being in the return state, that is, the nitrogen spring is used to drive the sliding mechanism to move from the in-place state to the return state, and the press is used to drive the sliding mechanism to move from the return state to the in-place state.

[0046] Compared with the prior art, the nitrogen spring pressure monitoring device provided by the present application has the following characteristics: when the press is running, the pressure monitoring component monitors the pressure data of the nitrogen spring and transmits the pressure data to the collector. The collector receives the pressure data of the pressure monitoring component. The collector is used to receive the pressure data of the pressure monitoring component and to trigger the press to perform corresponding operations according to the pressure data. This scheme can not only monitor the pressure of the nitrogen spring, but also the collector is electrically connected to the pressure monitoring component and the press through a transmission line, so that the electrical signal propagation speed between the pressure monitoring component, the collector and the press is fast, so that the press can promptly execute shutdown, alarm shutdown or alarm non-stop operation when the pressure of the nitrogen spring is abnormal, effectively preventing the mold used for the nitrogen spring from being damaged and reducing the scrap rate of parts.

[0047] In one embodiment, the collector is specifically used to send an alarm signal to the press when it is determined that the pressure data is outside the set range, and the alarm signal is used to trigger the press to execute the operation of stopping, stopping with alarm, or not stopping with alarm. It can be understood that the collector itself can determine whether the pressure data is within the preset range.

[0048] Optionally, the collector includes a receiving module, a processing module and a sending module, the receiving module is used to collect pressure data monitored by the pressure monitoring component, the processing module is used to determine whether the pressure data is within a preset range, and generate first information based on the pressure data, and the sending module is used to send the first information to the press. If the pressure data is within the preset range, it means that the pressure of the nitrogen spring is normal, then the first information generated by the collector based on the pressure data is a normal operating signal, and the normal operating signal can be sent to the press, at this time, the press operates normally according to the normal operating signal. If the pressure data is not within the preset range, it means that the pressure of the nitrogen spring is abnormal, then the first information generated by the collector based on the pressure data is an alarm signal, and the alarm signal is sent to the press, at this time, the press executes a shutdown, alarm shutdown, or alarm non-shutdown operation according to the alarm signal.

[0049] In another embodiment of the present application, the press is also used to determine whether the pressure data is within a preset range, and whether to execute a shutdown, alarm shutdown or alarm non-stop operation based on the judgment result, that is, the press has the function of determining whether the pressure data is within a preset range. It can be understood that after the collector receives the pressure data of the pressure monitoring component, the collector sends the pressure data to the press, and the press judges the pressure data. If the pressure data is within the preset range, it indicates that the pressure of the nitrogen spring is normal and the press operates normally. If the pressure data is not within the preset range, it indicates that the pressure of the nitrogen spring is abnormal, and the press executes a shutdown, alarm shutdown or alarm non-stop operation.

[0050] Optionally, the press can execute a shutdown operation, an alarm shutdown operation, or an alarm non-stop operation according to the degree of abnormal pressure of the nitrogen spring. For example, the normal pressure value of the nitrogen spring is above 10Mpa. If the pressure value of the nitrogen spring is less than 10Mpa and greater than or equal to 9Mpa, it means that the abnormal pressure degree of the nitrogen spring is relatively mild, and the press executes an alarm non-stop operation to remind the staff. If the pressure value of the nitrogen spring is less than 9Mpa, it means that the abnormal pressure degree of the nitrogen spring is relatively serious, and the press executes a shutdown operation or an alarm and shutdown operation. Of course, the press can also follow the preset instructions. As long as the pressure of the nitrogen spring is abnormal, the press can choose to execute a shutdown operation, an alarm shutdown operation, or an alarm non-stop operation.

[0051] Among them, the shutdown can be an emergency shutdown or a normal shutdown, which is selected according to the degree of abnormal pressure of the nitrogen spring. For example, the normal pressure value of the nitrogen spring is above 10Mpa. If the pressure value of the nitrogen spring is greater than or equal to 5Mpa and less than 9Mpa, the press performs a normal shutdown operation. If the pressure value of the nitrogen spring is less than 5Mpa, the press performs an emergency shutdown operation.

[0052] In one embodiment of the present application, the collector is also connected to the server by radio, and the server is connected to the terminal by radio. The collector is also used to transmit first information to the server according to the pressure data, and the server is used to transmit second information to the terminal according to the first information.

[0053] Optionally, the collector is connected to the server by radio via a gateway. Therefore, when the nitrogen spring pressure monitoring device is used to monitor the pressure of the nitrogen spring, a gateway setting is required so that the collector and the server are connected by radio via the gateway.

[0054] It should be noted that when the press is not running, the collector transmits the first information to the server according to the pressure data, and the server transmits the second information to the terminal according to the first information. When the press is running, the collector transmits the first information to the server according to the pressure data, and the server transmits the second information to the terminal according to the first information. When the press is running and not running, the collector transmits the first information to the server according to the pressure data, and the server transmits the second information to the terminal according to the first information.

[0055] The above technical solution transmits first information to the server according to the pressure data monitored by the pressure monitoring component through the collector, and the server transmits second information to the terminal according to the first information, so as to realize wireless monitoring of the pressure condition of the nitrogen spring. In this way, the staff can obtain the pressure condition of the nitrogen spring through the client on the terminal even if they are not on site, so that when the pressure of the nitrogen spring is abnormal, the staff can immediately handle the abnormality, especially before the press is operated. If the staff learns through the client on the terminal that the pressure of the nitrogen spring is insufficient, it can be inflated in time to prevent in advance, so as to avoid the press being shut down due to insufficient pressure of the nitrogen spring when the press is running, affecting the progress of parts processing, or causing abnormal quality of parts.

[0056] Optionally, clients such as email, WeChat and Feishu can be run on the terminal. For example, if the client is Feishu, when the press is not running, that is, before the press is running, the pressure monitoring component monitors the pressure data of the nitrogen spring and transmits the pressure data to the collector, which receives the pressure data of the pressure monitoring component and wirelessly sends the first information to the server according to the pressure data. The server sends the second information to Feishu according to the first information, so that the staff can view the second information through Feishu to know the pressure status of the nitrogen spring.

[0057] In one embodiment, the collector is also used to determine whether the pressure data is within a preset range, and to generate the first information based on the pressure data, that is, the collector has the function of determining whether the pressure data is within a preset range. At this time, the second information may be the same as the first information. At the same time, the preset range data of the nitrogen spring may also be set on the server, and the server may transmit the preset range data to the collector through the gateway. For example, if the pressure data is outside the preset range, indicating that the pressure of the nitrogen spring is abnormal, the collector generates an early warning signal based on the pressure data, and transmits the early warning signal to the server, and the server sends the early warning signal to the terminal. It can be understood that if the pressure data is within the preset range, the collector may not send information to the server.

[0058] In another embodiment of the present application, the server is also used to determine whether the pressure data is within a preset range, and to generate second information based on the first information, that is, the server has the function of determining whether the pressure data is within a preset range, the first information may be pressure data, and the second information may be different from the first information. It is understandable that after the collector receives the pressure data of the pressure monitoring component, the collector sends the pressure data to the server wirelessly through the gateway, and the server determines the pressure data. If the pressure data is outside the preset range, it indicates that the pressure of the nitrogen spring is abnormal. The server generates an early warning signal and transmits the early warning signal to the terminal. It is understandable that if the server determines that the pressure data is within the preset range, it indicates that the pressure of the nitrogen spring is normal, and the server may not send information to the terminal.

[0059] In one embodiment of the present application, see Figure 2 The pressure monitoring component includes a pressure gauge and a pressure sensor. The pressure gauge is connected to the nitrogen spring through a pipeline. The pressure gauge is used to monitor the pressure data of the nitrogen spring. The pressure sensor is electrically connected to the pressure gauge through a transmission line. The collector is electrically connected to the pressure sensor through a transmission line. The pressure sensor is used to collect the pressure data monitored by the pressure gauge and send the pressure data to the collector.

[0060] The above technical solution monitors the pressure data of the nitrogen spring through a pressure gauge, the pressure sensor collects the pressure data monitored by the pressure gauge, and transmits the pressure data to the collector through a transmission line. The structure is simple and is conducive to reducing the cost of use. Especially when the nitrogen spring itself is connected to a pressure gauge, it can be directly connected to the pressure sensor, which is conducive to reducing the difficulty of improvement.

[0061] In one embodiment of the present application, the pressure gauge is provided with a gas interface for deflating and / or inflating the nitrogen spring.

[0062] The above technical solution, by providing a gas interface for deflating and / or inflating the nitrogen spring on the pressure gauge, is conducive to improving maintenance convenience and saving maintenance operation time. For example, since the nitrogen spring that cooperates with the sliding mechanism of the stamping die is installed inside the stamping die, when the stamping die is subjected to offline maintenance operations and it is necessary to push the sliding mechanism into place for grinding or other operations, in the prior art, it is generally necessary to remove the nitrogen spring so that the sliding mechanism can be pushed into place manually without being affected by the reaction force of the nitrogen spring. In this way, the entire stamping die needs to be disassembled step by step to remove the nitrogen spring, and the stamping die needs to be reinstalled. After the maintenance is completed, the stamping die needs to be disassembled again to reinstall the nitrogen spring. The operation is extremely cumbersome and takes about 8 hours. In this application, please refer to Figure 3 and Figure 4 By setting an air interface on the pressure gauge, if it is necessary to perform offline maintenance work on the stamping die when the sliding mechanism is in place, the nitrogen spring can be deflated directly through the air interface. After the nitrogen spring is deflated, the sliding mechanism can be manually pushed to the in-place state. In this way, the stamping mold can be directly maintained offline without the need to repeatedly dismantle the entire mechanism of the stamping mold. After the maintenance is completed, the air interface on the pressure gauge is directly inflated to restore the sliding mechanism to a normal return state, which takes about 2 hours. Therefore, each maintenance operation can save about 6 hours of dismantling and reinstallation time.

[0063] An exemplary description is given of the installation of a nitrogen spring pressure monitoring device on a mold. The nitrogen spring is installed inside a mold shell, a through hole is opened at a position of the mold shell corresponding to the nitrogen spring, a pressure gauge is installed outside the mold shell, and then a pipeline connecting the pressure gauge and the nitrogen spring passes through the through hole on the mold shell, a pressure sensor is installed outside the mold shell and located near the pressure gauge, the pressure sensor is electrically connected to the pressure gauge through a transmission line, a collector is installed on the outside of the mold shell and located near the pressure sensor, the collector is electrically connected to the pressure sensor through a transmission line, the collector is electrically connected to the mold electrical box on the press through the transmission line, a gateway interface is set, the collector is connected to the gateway interface through the transmission line, the gateway interface is connected to the server through a wireless network domain, so that the collector is wirelessly connected to the server through the gateway interface.

[0064] In one embodiment of the present application, see Figure 1 , the collector is detachably connected to the press through a transmission line. By detachably connecting the collector to the press through a transmission line, the collector can be separated from the press. For example, when it is necessary to separate the stamping die with a nitrogen spring pressure monitoring device and a nitrogen spring from the press, the transmission line connecting the collector to the press can be separated, or the transmission line connected to the collector can be separated from the press, thereby replacing stamping dies of different models with nitrogen spring pressure monitoring devices and nitrogen springs.

[0065] Optionally, the press is provided with an adapter, one end of the transmission line is connected to the collector, and the other end of the transmission line is detachably plugged into the adapter on the press. Alternatively, the collector is provided with an adapter, one end of the transmission line is connected to the press, and the other end of the transmission line is detachably plugged into the adapter on the collector.

[0066] The embodiment of the present application also provides a monitoring method for a nitrogen spring pressure monitoring device. Based on the nitrogen spring pressure monitoring device of any one of the above embodiments, the monitoring method for the nitrogen spring pressure monitoring device includes:

[0067] When the press is running, the pressure monitoring component monitors the pressure data of the nitrogen spring;

[0068] The pressure monitoring component transmits the pressure data to the collector;

[0069] The collector receives the pressure data from the pressure monitoring component and triggers the press to perform corresponding operations based on the pressure data.

[0070] The monitoring method of the nitrogen spring pressure monitoring device of the present application adopts the above-mentioned nitrogen spring pressure monitoring device. When the press is running, the pressure monitoring component monitors the pressure data of the nitrogen spring and transmits the pressure data to the collector. The collector receives the pressure data of the pressure monitoring component. The collector is used to receive the pressure data of the pressure monitoring component and to trigger the press to perform corresponding operations according to the pressure data. This scheme can not only monitor the pressure of the nitrogen spring, but also the collector is electrically connected to the pressure monitoring component and the press through a transmission line, so that the electrical signal propagation speed between the pressure monitoring component, the collector and the press is fast, so that the press can execute shutdown, alarm shutdown or alarm non-stop operation in time when the pressure of the nitrogen spring is abnormal, effectively preventing the processing equipment used for the nitrogen spring from being damaged and reducing the scrap rate of parts.

[0071] Optionally, when the collector determines that the pressure data is outside a set range, it sends an alarm signal to the press, and the alarm signal is used to trigger the press to execute a shutdown, an alarm shutdown, or an alarm without shutdown operation.

[0073] When the press is running and / or not running, the collector transmits first information to the server according to the pressure data, and the server transmits second information to the terminal according to the first information.

[0074] The above technical solution transmits first information to the server according to the pressure data monitored by the pressure monitoring component through the collector, and the server transmits second information to the terminal according to the first information, so as to realize wireless monitoring of the pressure condition of the nitrogen spring. In this way, the staff can obtain the pressure condition of the nitrogen spring through the client on the terminal even if they are not on site, so that when the pressure of the nitrogen spring is abnormal, the staff can immediately handle the abnormality, especially before the press is operated. If the staff learns through the client on the terminal that the pressure of the nitrogen spring is insufficient, it can be inflated in time to prevent in advance, so as to avoid the press being shut down due to insufficient pressure of the nitrogen spring when the press is running, affecting the progress of parts processing, or causing abnormal quality of parts.

[0076] Compared with the prior art, the processing equipment of the present application adopts the above-mentioned nitrogen spring pressure monitoring device. When the press is running, the pressure monitoring component monitors the pressure data of the nitrogen spring and transmits the pressure data to the collector. The collector receives the pressure data of the pressure monitoring component. The collector is used to receive the pressure data of the pressure monitoring component and to trigger the press to perform corresponding operations according to the pressure data. This scheme can not only monitor the pressure of the nitrogen spring, but also the collector is electrically connected to the pressure monitoring component and the press through a transmission line, so that the electrical signal propagation speed between the pressure monitoring component, the collector and the press is fast, so that the press can execute shutdown, alarm shutdown or alarm non-stop operation in time when the pressure of the nitrogen spring is abnormal, effectively preventing the processing equipment used for the nitrogen spring from being damaged and reducing the scrap rate of parts.
