Description

Technical Field

[0001] The present invention belongs to the technical field of hydraulic presses, and particularly relates to a detection device for hydraulic presses. Background Art

[0002] A hydraulic press (also known as an oil press) is a machine that uses the static pressure of liquid to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing and forming processes, such as forging, stamping, cold extrusion, straightening, bending, flanging, sheet metal drawing, powder metallurgy, pressing, etc. A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to achieve various processes. A hydraulic press generally consists of three parts: the machine, the power system and the hydraulic control system.

[0003] When the hydraulic press is working, its upper template is pressed downward with the lower template to form a part. During the processing, manual placement and removal of parts are generally required. When manually operated, if the upper template and the lower template are still pressed relative to each other, there will be a risk of people being pinched, which poses certain safety hazards. The safety of the staff cannot be guaranteed. During the production process of the hydraulic press, it is often necessary to inspect the metal plates that need to be processed to ensure the quality of the hydraulic press production. Existing devices generally require manual measurement and selection of appropriate hydraulic force. Manual measurement takes a lot of time, and the factory's production efficiency cannot be improved.

[0038] Two sets of air compressors, an external motor for roller conveyor 2, two sets of manipulators, four sets of electric valves, five sets of pressure sensors, and two sets of cameras are all connected to the equipment program signal.

[0039] Plate thickness detection operation:

[0040] When the staff needs to use a hydraulic press to process metal sheets, the staff first turns on the external power supply, the inspection box 1 starts, the roller conveyor 2 starts to run, the equipment program starts, and then the staff places the metal sheet on the roller conveyor 2. The metal sheet is driven to the inspection box 1 at the rear. At this time, the equipment program locates and identifies the position of the metal sheet through the second camera 34. When the metal sheet moves to the inspection box 1, the equipment program controls the external motor of the roller conveyor 2 to stop, and the two sets of air compressors are started. The first air compressor 12 pumps compressed air into the first telescopic cylinder 14 and the second telescopic cylinder 15 through the built-in ventilation pipeline of the inspection box 1. At this time, the equipment program detects the signal of the first pressure sensor 161 and compares it with the set value. The equipment program sets the pump air pressure of the first air compressor 12 to M1, M2, and M3. M1 is the minimum pump air value, M3 is the maximum pump air value, and the set pressure value is N1. The equipment program first controls the first air compressor 12 to pump air into the first telescopic cylinder 14 and the second telescopic cylinder 15. The pumping pressure of the machine 12 is M1, and the two sets of telescopic cylinders extend downward. At this time, the equipment program detects the value of the first pressure sensor 161. If it is greater than or equal to N1, the equipment program proceeds to the next operation. If it is less than N1, the equipment program controls the pumping pressure of the first air compressor 12 to increase to M2. At this time, the equipment program detects the value of the first pressure sensor 161 again. If it is greater than or equal to N1, the equipment program proceeds to the next operation. If it is less than N1, the equipment program controls the pumping pressure of the first air compressor 12 to increase to M3. At this time, the equipment program detects the value of the first pressure sensor 161 again. If it is greater than or equal to N1, the equipment program proceeds to the next operation. The metal plate has a certain thickness. When the pumping pressure is increased to M3, the pressure value will not be less than N1. After detecting the thickness of the metal plate, the equipment program will send the data to the staff, so that the staff can modify the processing pressure of the hydraulic press according to the different thicknesses of the metal plate.

[0041] By using two sets of telescopic cylinders in conjunction with the first pressure sensor 161, the thickness of the metal sheets to be processed can be detected, which makes it easier for the staff to modify the hydraulic force of the hydraulic press to ensure that metal sheets of different thicknesses can be processed normally, and prevent incomplete or inadequate processing of thin metal sheets, thereby reducing the rework rate of the factory and ensuring that thin metal sheets will not have processing dead corners.

[0042] Plate size detection operation:

[0043] After completing the above operations, the equipment program controls the plate size detection operation. After the equipment program controls the plate thickness detection, it controls the second air compressor 13 to open and first performs the plate width size detection. The equipment program sets the pump air pressure of the second air compressor 13 to X1, X2, and X3, X1 is the minimum value, X3 is the maximum value, and the set pressure value is Y1. The equipment program first controls the pump air pressure of the second air compressor 13 to X1, the first electric valve 512 and the second electric valve 522 are opened, and the second air compressor 13 pumps compressed air into the third telescopic cylinder 51 and the fourth telescopic cylinder 52. The two groups of telescopic cylinders extend outward. At this time, the equipment program controls the second pressure sensor 511 and the third pressure sensor The values ​​of the two pressure sensors 521 are detected and compared with the set values. If the values ​​of the two pressure sensors are ≥ Y1, the equipment program proceeds to the next operation. If the values ​​of the two pressure sensors are < Y1, the equipment program increases the pump air pressure to X2. At this time, the equipment program again detects the values ​​of the two pressure sensors and compares them with the set values. If the values ​​of the two pressure sensors are ≥ Y1, the equipment program proceeds to the next operation. If the values ​​of the two pressure sensors are < Y1, the equipment program increases the pump air pressure to X3. When the pump air pressure is increased to X3, since the plate itself has a certain thickness, the value of the two pressure sensors will not be < Y1. Then the equipment program controls the plate length size detection.

[0044] The device program controls the first electric valve 512 and the second electric valve 522 to close, the third electric valve 532 and the fourth electric valve 542 to open, and the second air compressor 13 pumps compressed air into the other two sets of telescopic cylinders to detect the length of the plate. The device program first controls the pumping pressure of the second air compressor 13 to be X1, and the second air compressor 13 pumps compressed air into the fifth telescopic cylinder 53 and the sixth telescopic cylinder 54. The two sets of telescopic cylinders extend outward. At this time, the device program detects the values ​​of the fourth pressure sensor 531 and the fifth pressure sensor 541 and compares them with the set values. If the values ​​of the two sets of pressure sensors are ≥Y1 The equipment program then proceeds to the next operation. If the values ​​of the two sets of pressure sensors are less than Y1, the equipment program increases the pump air pressure to X2. At this time, the equipment program again detects the values ​​of the two sets of pressure sensors and compares them with the set values. If the values ​​of the two sets of pressure sensors are ≥ Y1, the equipment program proceeds to the next operation. If the values ​​of the two sets of pressure sensors are less than Y1, the equipment program increases the pump air pressure to X3. When the pump air pressure is increased to X3, since the plate itself has a certain length, the value of the two sets of pressure sensors will not be less than Y1. Then the equipment program controls the plate length size detection, and then the equipment program controls the next operation.

[0045] By using four sets of telescopic cylinders, the second air compressor 13 and the equipment program in conjunction, the length and width of the metal plate to be processed can be detected, making the size detection of the metal plate more accurate, facilitating the hydraulic press 4 to select the appropriate hydraulic force for subsequent processing, and preventing the hydraulic force from not matching the size of the metal plate, resulting in incomplete processing or leaving dead corners, effectively increasing the factory's output, reducing production processes, and eliminating the need to use another hydraulic press 4 for processing of different sizes, effectively improving the factory's production efficiency, eliminating the need for manual measurement, and reducing the burden on staff.

[0046] Clamping operation:

[0047] After the above-mentioned inspection operation is completed, the equipment program controls the external motor of the roller conveyor 2 to start and transport the inspected metal sheet backward. At this time, the equipment program locates and identifies the position of the metal sheet through the first camera 33. Then, the equipment program controls two sets of manipulators to clamp the metal sheet and place it on the operating table of the hydraulic press 4. The staff controls the hydraulic press 4 to use the appropriate hydraulic force to process the metal sheet based on the inspection data. After the processing is completed, the staff can use tools to remove the processed metal sheet.

[0048] By coordinating the use of two sets of manipulators and the equipment program, the manipulators can be used to directly clamp the inspected metal plates and place them into the hydraulic press 4 while the hydraulic press 4 is running, without the need for manual clamping by the staff. This prevents safety problems from occurring during the hydraulic process, reduces safety hazards during production, protects the safety of the staff, and can also effectively reduce the physical exertion of the staff and improve production efficiency.
