Description

Technical Field

[0001] This utility model relates to the field of CNC hydraulic technology, specifically to a CNC hydraulic control module. Background Technology

[0002] In traditional CNC hydraulic systems, the stroke of the main hydraulic mechanism's pressure bar is typically long, resulting in long work cycle times and low efficiency. Especially in work scenarios requiring frequent and rapid movements, the long-stroke main hydraulic mechanism cannot meet the demands of high-efficiency production. Furthermore, long-stroke hydraulic actions increase energy consumption and reduce the overall performance of the system. For example, in some stamping and forming processes, the hydraulic mechanism needs to frequently perform pressing and resetting actions; a long-stroke main hydraulic mechanism significantly prolongs the time of each work cycle, impacting production efficiency.

[0004] Therefore, the purpose of this utility model is to provide a CNC hydraulic control module that solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0023] This utility model discloses a CNC hydraulic control module.

[0024] Example 1

[0025] Reference Figure 1-3 A CNC hydraulic control module includes a base plate 1 and a first U-shaped plate 2. The first U-shaped plate 2 is fixedly disposed on the upper surface of the base plate 1. A first hydraulic cylinder 3 is fixedly disposed on the top of the first U-shaped plate 2. The piston rod of the first hydraulic cylinder 3 extends to the lower part of the first U-shaped plate 2. A hexagonal hole is opened at the end of the piston rod of the first hydraulic cylinder 3. A hexagonal prism 6 is slidably inserted into the interior of the hexagonal hole. A pressure rod 7 is fixedly disposed at the lower end of the hexagonal prism 6. A first hydraulic cylinder 7 is fixedly sleeved on the outer wall of the piston rod end of the first hydraulic cylinder 3. The second U-shaped plate 4 and the upper surface of the first U-shaped plate 2, located on both sides of the first hydraulic cylinder 3, are provided with first through holes. A vertical rod 5 is movably sleeved inside the first through hole. The lower end of the vertical rod 5 is fixedly connected to the second U-shaped plate 4, so that the first hydraulic cylinder 3 can stably push the second U-shaped plate 4 to move. A first anti-detachment block is fixedly provided at the upper end of the vertical rod 5 to prevent the vertical rod 5 from slipping out of the first through hole as much as possible. The two sides of the second U-shaped plate 4 are provided with a transmission mechanism that drives the pressure rod 7 to move relative to the piston rod of the first hydraulic cylinder 3.

[0026] Example 2

[0027] Reference Figure 1-3The transmission mechanism includes a second hydraulic cylinder 14 and a push rod 9. Two second hydraulic cylinders 14 are fixedly mounted on the outer walls of both sides of the second U-shaped plate 4. The piston rod ends of the second hydraulic cylinders 14 extend to the inner side of the second U-shaped plate 4. A fixing ring 8 is fixedly sleeved on the outer wall of the pressure rod 7. The push rod 9 is positioned between the piston rod end of the second hydraulic cylinder 14 and the fixing ring 8. Both ends of the push rod 9 are rotatably connected to connecting blocks 11 via shaft pins 10. One connecting block 11 is fixedly connected to the fixing ring 8 on one side, and the other connecting block 11 is fixedly connected to the corresponding first hydraulic cylinder 14. The piston rod of a hydraulic cylinder 3 is fixedly connected to the end of the cylinder. The side wall of the second U-shaped plate 4 and both sides of the second hydraulic cylinder 14 are provided with second through holes. A crossbar 13 is slidably arranged inside the second through hole. A connecting rod 12 is fixedly arranged at the end of the crossbar 13 near the push rod 9. The connecting rod 12 is fixedly connected to the corresponding connecting block 11, so that the second hydraulic cylinder 14 can stably push the push rod 9 to rotate. A second anti-disengagement block is fixedly arranged at the end of the crossbar 13 away from the push rod 9 to prevent the crossbar 13 from slipping out of the second through hole as much as possible.

[0028] In this invention, during use, the piston rod of the first hydraulic cylinder 3 descends, causing the second U-shaped plate 4 and the pressure rod 7 to descend synchronously. The vertical rod 5 slides within the through hole of the first U-shaped plate 2 to ensure stable movement. When the pressure rod 7 needs to be quickly adjusted, the piston rod of the second hydraulic cylinder 14 extends and pushes the fixing ring 8 through the push rod 9 and the shaft pin 10, causing the pressure rod 7 to move rapidly relative to the piston rod of the main hydraulic cylinder. The hexagonal prism 6 slides within the hexagonal hole to achieve fine-tuning of the stroke. The horizontal rod 13 is linked with the connecting rod 12 to limit the swing range of the push rod 9 and ensure precise action. After the operation is completed, the piston rods of the main and auxiliary hydraulic cylinders are reset, and the vertical rod 5 and the horizontal rod 13 are respectively limited by the first anti-detachment block and the second anti-detachment block to prevent detachment.
