[0002] A hydraulic press is a machine that uses liquid as its working medium and is designed based on Pascal's principle to transfer energy to achieve various processes. A hydraulic press generally consists of three parts: the main body, the power system, and the hydraulic control system. Besides forging, hydraulic presses can also be used for straightening, pressing, packaging, briquetting, and plate pressing. Hydraulic presses include water presses and oil presses.

[0003] Hydraulic presses are prone to malfunctions during use. However, since hydraulic presses consist of multiple systems, the required testing methods are diverse. Typically, repair technicians rely on their experience to troubleshoot before using instruments for measurement, which is time-consuming and labor-intensive. Therefore, we propose a fault detection device for hydraulic presses to address these issues. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are: the fault detection device of this hydraulic press not only realizes the hydraulic oil detection function and the temperature and pressure detection function, but also realizes the contact detection function;

[0012] (1) By setting up a hydraulic oil detection structure, the present invention is beneficial as follows: When in use, the input pipe on the right side of the observation bucket is inserted into the hydraulic oil tank.

[0013] (2) By setting up a temperature and pressure detection structure, the present invention is beneficial as follows: when hydraulic oil is used in conjunction with a hydraulic press, insufficient pressure or excessive oil temperature may cause thermal deformation and oil oxidation due to sealing. The hydraulic press delivery pipe is connected to the pressure detection port and temperature detection port at the rear end of the monitoring host. The temperature and pressure of the hydraulic oil delivered by the hydraulic press are monitored by the temperature gauge and pressure gauge on the top of the monitoring host to detect whether there are any abnormalities in the temperature and pressure of the hydraulic oil delivered by the hydraulic press, thereby realizing the temperature and pressure detection function.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 An embodiment of this utility model provides a fault detection device for a hydraulic press, including a monitoring host 4, a display screen 3 embedded in the front end of the monitoring host 4, control buttons 2 installed on both sides of the front end of the monitoring host 4, a fixed seat 7 installed on the right side of the monitoring host 4, an observation tank 6 installed inside the fixed seat 7, an oil extractor 9 installed on the top of the observation tank 6, a moisture meter 10 inserted into the top of the observation tank 6, a viscosity detector 11 installed at the bottom of the observation tank 6, an input pipe 12 connected to the right side of the observation tank 6, and a storage drawer 8 installed at the front end of the monitoring host 4.

[0022] The observation bucket 6 is fixed to the right side of the monitoring host 4 by the fixing seat 7. The moisture measuring device 10 and the viscosity detector 11 are respectively inserted into the top and bottom of the observation bucket 6. The moisture measuring device 10 and the viscosity detector 11 are electrically connected to the monitoring host 4 through wires. The oil extractor 9 is connected to the input pipe 12 through the observation bucket 6.

[0023] Specifically, such as Figure 1 and Figure 3As shown, by setting up a hydraulic oil detection structure, when in use, the input pipe 12 on the right side of the observation tank 6 is inserted into the hydraulic oil tank. The oil pump 9 is started by the control button 2 at the front end of the monitoring host 4 to pump the hydraulic oil into the observation tank 6 to check the color of the hydraulic oil inside the observation tank 6 and whether there are impurities. At the same time, the moisture measuring device 10 at the top of the observation tank 6 and the viscosity detector 11 at the bottom of the observation tank 6 respectively detect the moisture and viscosity of the hydraulic oil inside the observation tank 6 to determine whether the fault is caused by the aging of the hydraulic oil, thus realizing the hydraulic oil detection function.

[0024] The top of the monitoring host 4 is equipped with a temperature gauge 1 and a pressure gauge 5, and the rear end of the monitoring host 4 is provided with a pressure detection port 13 and a temperature detection port 14.

[0025] Pressure detection port 13 is connected to pressure gauge 5 on top of monitoring host 4 through monitoring host 4, and temperature detection port 14 is connected to temperature gauge 1 on top of monitoring host 4 through monitoring host 4.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, by setting up a temperature and pressure detection structure, when hydraulic oil is used in conjunction with a hydraulic press, if the pressure is insufficient due to sealing or the oil temperature is too high, resulting in thermal deformation and oil oxidation, the hydraulic press delivery pipe is connected to the pressure detection port 13 and temperature detection port 14 at the rear end of the monitoring host 4. The temperature gauge 1 and pressure gauge 5 on the top of the monitoring host 4 are used to monitor whether there are any abnormalities in the temperature and pressure of the hydraulic oil delivered by the hydraulic press, thereby realizing the temperature and pressure detection function.

[0027] The rear end of the monitoring host 4 is connected to a connecting wire 17, the rear end of the connecting wire 17 is connected to a vibration monitor 15, and a card holder 16 is provided on the right side of the rear end of the monitoring host 4.

[0028] The vibration monitor 15 is connected to the monitoring host 4 via the connecting wire 17, and the vibration monitor 15 is fixed to the rear end of the monitoring host 4 by snapping it into the snap-fit ​​socket 16.

[0029] Specifically, such as Figure 2 and Figure 4 As shown, by setting up a contact detection structure, when in use, the vibration monitor 15 is taken out from the snap-fit ​​seat 16 at the rear end of the monitoring host 4, and the vibration monitor 15 is attached to the outer wall of the hydraulic cylinder on the hydraulic press. The vibration monitor 15 detects the vibration amplitude of the hydraulic cylinder during operation to determine whether the inside of the hydraulic press is loose from the mechanical parts, thereby realizing the contact detection function.

[0030] Working Principle: When using hydraulic oil with a hydraulic press, this invention addresses situations where insufficient pressure due to sealing issues or excessively high oil temperature can lead to thermal deformation and oil oxidation. The hydraulic press delivery pipe is connected to the pressure detection port 13 and temperature detection port 14 at the rear of the monitoring host 4. The temperature gauge 1 and pressure gauge 5 on the top of the monitoring host 4 are used to monitor the temperature and pressure of the hydraulic oil being delivered by the hydraulic press for any abnormalities. Then, the input pipe 12 on the right side of the observation tank 6 is inserted into the hydraulic oil tank. The oil extractor 9 is activated by the control button 2 at the front of the monitoring host 4, drawing hydraulic oil into the observation tank 6. To check the color and presence of impurities in the hydraulic fluid inside the observation tank 6, the moisture meter 10 at the top of the observation tank 6 and the viscosity detector 11 at the bottom of the observation tank 6 are used to detect the moisture and viscosity of the hydraulic oil inside the observation tank 6 to determine if the fault is caused by aging hydraulic oil. At the same time, the vibration monitor 15 is removed from the snap-fit ​​seat 16 at the rear end of the monitoring host 4 and attached to the outer wall of the hydraulic cylinder on the hydraulic press. The vibration monitor 15 is used to detect the vibration amplitude of the hydraulic cylinder during operation to determine whether there is any looseness between the hydraulic press and mechanical parts.
