Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil circuits, in particular to a hydraulic oil circuit fault early warning device for a cold shearing machine of a round bar production line. Background Art

[0002] The cold shears used in round bar production lines are used for cutting materials in the metalworking industry. The hydraulic circuit plays a crucial role in these shears. It provides power and control, ensuring the shear blades close accurately and smoothly for precise cutting. The hydraulic system generates high-pressure oil flow through a hydraulic pump, which is converted into mechanical energy by a cylinder or hydraulic motor to drive the shear blades. The basic function of the fault warning device is to monitor key hydraulic system parameters such as pressure, temperature, and flow in real time and issue an alarm if an anomaly is detected.

[0003] Common fault warning devices are based on sensor technology, which transmits collected data to a central processing unit and analyzes the data using preset thresholds and algorithms. Once signs of deviation from the normal operating range are detected, the system triggers an early warning, notifying the operator or automatically starting a protection program.

[0004] However, since this method requires the use of a probe for detection, the sensor is susceptible to electromagnetic interference and cannot be applied to various environmental conditions, especially in environments with high temperature, humidity or corrosive substances. In addition, in order to ensure the accuracy of probe detection, regular maintenance is required, which makes the early warning device inconvenient to use and cannot meet the working requirements of hydraulic oil circuit detection. Therefore, a hydraulic oil circuit fault early warning device for the cold shear of a round bar production line is proposed. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a technical solution, a hydraulic oil circuit fault warning device for a round bar production line cold shear, comprising a main assembly cylinder 1, an auxiliary assembly cylinder 2, a pipe 3, a first flange 4, a first buzzer alarm light 5, an insert plate 6, a first trigger rod 7, a plug 8, a first spring 9, a ring seat 10, a sealing head 11, a second trigger rod 12, a second spring 13, a second flange 14, a second buzzer alarm light 15, a pressure relief hole 16, a connecting rod 17, a baffle 18 and a matching hole 19:

[0027] See also Figure 1 , main assembly cylinder 1, the lower right side of the main assembly cylinder 1 is connected to the auxiliary assembly cylinder 2, the bottom of the main assembly cylinder 1 is installed with a pipe 3, the outside of the pipe 3 is installed with a first flange 4, and the top of the main assembly cylinder 1 is equipped with a first buzzer alarm light 5;

[0028] See also Figure 2 , the insert plate 6 is inserted into the upper part of the inner cavity of the main assembly cylinder 1, the first trigger rod 7 is inserted into the interior of the insert plate 6, the bottom end of the first trigger rod 7 is connected to the plug 8, the right end of the auxiliary assembly cylinder 2 is installed with a second flange 14, and the right side of the second flange 14 is installed with a second buzzer alarm light 15;

[0029] See also Figure 4 , the ring seat 10 is inserted into the left side of the inner cavity of the auxiliary assembly cylinder 2, and a sealing head 11 is inserted into the interior of the ring seat 10. The right side of the sealing head 11 is coaxially connected to the second trigger rod 12. The inner contacts of the first buzzer alarm light 5 and the second buzzer alarm light 15 are aligned with the first trigger rod 7 and the second trigger rod 12. The outer sleeve of the first trigger rod 7 is provided with a first spring 9. The upper and lower ends of the first spring 9 are respectively connected to the corresponding positions on the inner side of the plug 6 and the plug 8. The outer sleeve of the second trigger rod 12 is provided with a second spring 13. Through the added plug 8 and the first trigger rod 7, after the first flange 4 is assembled on the outside of the oil circuit, when the internal pressure of the oil circuit increases, the plug 8 and the first trigger rod 7 can be pushed up, so that the first trigger rod The top of the plug 7 contacts the contact at the bottom of the first buzzer alarm light 5 to sound an alarm. When the pressure continues to increase, it pushes the sealing head 11 and the second trigger rod 12 to move, thereby causing the second buzzer alarm light 15 to sound an alarm. Since the plug 8, the sealing head 11, the first trigger rod 7 and the second trigger rod 12 are all simple mechanical structures and the alarm is triggered by movement, they are not easily susceptible to electromagnetic interference and are suitable for various environmental conditions, especially in environments with high temperature, humidity or corrosive substances. Compared with electronic sensors, they are lower in cost and do not require an external power supply to work during the triggering process. In the event of a power failure, the warning system can still operate normally, thereby improving the convenience of using the warning device.

[0030] See also Figure 1The main assembly tube 1 is provided with pressure relief holes 16 on the outer upper side. The number of pressure relief holes 16 is 3-6 groups.

The shape of the baffle 18 is arc-shaped. A matching hole 19 is opened on the lower side of the inner part of the baffle 18. The size of the matching hole 19 is the same as that of the pressure relief hole 16. The vertical position of the matching hole 19 and the pressure relief hole 16 are staggered with each other, which can drive the synchronous rise of the connecting rod 17 and the baffle 18 during the rising process of the first trigger rod 7, so that the matching hole 19 can coincide with the pressure relief hole 16, and pressure relief can be performed, so that auxiliary pressure relief is performed at the same time as the alarm, avoiding excessive pressure in the oil circuit when it cannot be handled in time.

[0031] In this solution, by adding the plug 8 and the first trigger rod 7, after the first flange 4 is assembled outside the oil circuit, when the pressure inside the oil circuit increases, the plug 8 and the first trigger rod 7 can be pushed up, so that the top of the first trigger rod 7 contacts the contact at the bottom of the first buzzer alarm light 5 to alarm, and when the pressure continues to increase, it will push the sealing head 11 and the second trigger rod 12 to move, so that the second buzzer alarm light 15 will alarm. Since the plug 8, the sealing head 11, the first trigger rod 7 and the second trigger rod 12 are all simple mechanical structures and alarm by motion triggering, they are not easily affected by electricity. Magnetic interference is suitable for various environmental conditions, especially in environments with high temperature, humidity or corrosive substances, and is lower in cost than electronic sensors. At the same time, it does not require an external power supply to work during the triggering process, so that in the event of a power failure, the early warning system can still operate normally, improving the convenience of using the early warning device. At the same time, it can drive the synchronous rise of the connecting rod 17 and the baffle 18 during the rise of the first trigger rod 7, so that the matching hole 19 and the pressure relief hole 16 can coincide, and pressure relief can be performed, so that auxiliary pressure relief is performed at the same time as the alarm, avoiding excessive pressure in the oil circuit when it cannot be handled in time.
