Abstract
Description
Technical Field
[0001] This application relates to the field of CNC bending machine technology, and in particular to a high-efficiency CNC profile bending machine. Background Technology
[0002] With the continuous development of the machinery industry, bending machines have been used in many occasions. Traditional ordinary bending machines use ordinary motors, piston pumps, and ordinary hydraulic valves for control. During the bending process, the positioning accuracy is insufficient, and the consistency of products cannot be guaranteed during mass production.
[0003] Existing CNC bending machines often use ordinary motors and piston pumps with ordinary hydraulic valves to control the hydraulic system. Using servo motors and gear pumps with servo valves to control the hydraulic system is ineffective. Furthermore, the connection between the gear pump and servo valve via connecting pipes is not very secure, and the airtightness monitoring of the connection points is also poor, reducing the accuracy of hydraulic system control. Utility Model Content
[0004] This application provides a high-efficiency CNC profile bending machine to solve the problem mentioned in the background art that the hydraulic system of the CNC bending machine is not very effective and reduces the control accuracy of the hydraulic system by using the cooperation between servo motors, gear pumps and servo valves.
[0005] This application provides a high-efficiency CNC profile bending machine, including a servo motor. The output end of the servo motor is fixedly connected to a gear pump via a coupling. A connecting pipe is provided on the outer wall of the gear pump. A servo valve is detachably connected to one end of the connecting pipe. A connector is fixedly connected to the outer wall of the servo valve and engages with the outer wall of the connecting pipe. A turntable is threadedly connected to the outer wall of the connector. An external helix is provided on the outer wall of the connector. An internal helix is provided at the connection between the inner wall of the turntable and the external helix. A locking rod is slidably connected to the outer wall of the turntable and the outer wall of the connector. A sliding groove is provided at the connection between the outer wall of the turntable and the locking rod. A fixed plate is fixedly connected to the outer wall of the connector and slidably connected to the outer wall of the locking rod. A lifting groove is provided at the connection between the outer wall of the fixed plate and the locking rod. A locking groove is provided at the connection between the outer wall of the connecting pipe and the locking rod. An airtightness detector is installed on the outer wall of the connector.
[0006] Preferably, the turntable forms a rotating structure with the connector via an outer helix and an inner helix.
[0007] Preferably, the outer wall profile of the chute is inclined, and the outer wall profile of the lifting groove is horizontal.
[0008] Preferably, the clamp rod is arranged in a ring about the central axis of the connector, and the outer wall contour of the clamp rod is L-shaped.
[0009] Preferably, the connecting pipe and the clamp rod are slidably connected, the clamp slots and the clamp rods are configured in a one-to-one correspondence, and the clamp slots are set on the movement trajectory of the clamp rods.
[0010] Preferably, the specific model of the airtightness detector is CF-C01A.
[0011] Preferably, the monitoring area of the airtightness detector is the connection point between the servo valve and the connecting pipe.
[0012] Beneficial effects:
[0013] Considering that existing CNC bending machines often use ordinary motors and piston pumps with ordinary hydraulic valves to control the hydraulic system, using servo motors and gear pumps with servo valves to control the hydraulic system is not very effective. Furthermore, when installing the gear pump and servo valve through connecting pipes, the engagement between the connecting pipe and the servo valve is not very effective, and the airtightness monitoring of the connection points is not very effective, thus reducing the control accuracy of the hydraulic system.
[0014] In use, this invention involves installing a servo motor, gear pump, and servo valve within the hydraulic system of a CNC bending machine. This allows the servo motor, gear pump, and servo valve to control the CNC bending machine's hydraulic system. Simultaneously, during the installation of the gear pump and servo valve, a connecting pipe is inserted into the servo valve's connector. Rotating the turntable, with its external and internal spiral threads, causes the locking rod to slide synchronously along the inner walls of the slide and lifting grooves, inserting it into the inner wall of the locking groove. This achieves the desired engagement between the connector and the connecting pipe. An airtightness detector is installed at the connection point for convenient monitoring of the hydraulically supplied gas pressure, improving the hydraulic control accuracy of the CNC bending machine. Through program control, the bending accuracy reaches ≤0.1mm, ensuring product consistency during mass production.

A locking groove 13 is provided at the connection between the outer wall of the connecting pipe 3 and the locking rod 9. An airtightness detector 14 is installed on the outer wall of the connector 5.
[0032] The turntable 6 forms a rotating structure with the connector 5 through the outer spiral 7 and the inner spiral 8.
[0033] It facilitates the threaded connection between the outer spiral 7 and the inner spiral 8, and enables the turntable 6 to rotate on the outer wall of the connector 5 for convenient self-locking.
[0034] The outer wall of the slide 10 is inclined, while the outer wall of the lifting groove 12 is horizontal.

Simultaneously, during the installation of the gear pump 2 and servo valve 4, the connecting pipe 3 is inserted into the connector 5 of the servo valve 4. Rotating the turntable 6, with the threaded connection of the outer spiral 7 and inner spiral 8, causes the locking rod 9 to slide synchronously along the inner walls of the slide groove 10 and the lifting groove 12, inserting it into the inner wall of the locking groove 13. This achieves the effect of engaging and installing the connector 5 with the connecting pipe 3.
