Description

Technical Field

[0001] This utility model relates to the field of hydraulic press technology, specifically to a CNC four-column hydraulic press with automatic and precise feeding. Background Technology

[0002] In industrial production, traditional hydraulic presses rely heavily on manual labor or simple mechanical devices for feeding, resulting in low efficiency and large errors. The poor coordination between the oil pump, oil tank, and control valve in the pressing process can easily lead to product quality problems and equipment damage. Discharging often requires manual handling, which is labor-intensive and can easily damage products. Furthermore, there is a lack of real-time monitoring of parameters such as pressure, making it impossible to respond to abnormal pressure in a timely manner, which makes it difficult to ensure production safety and meet the requirements of modern industry for high efficiency, precision, and safety. Utility Model Content

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. Example:

[0022] like Figures 1-5 As shown, a CNC four-column hydraulic press for automatic and precise feeding includes a support assembly 1. A pressing platform 2 is located on the inner side of the lower end of the support assembly 1. Four sliding columns 3 are fixedly connected around the pressing platform 2. A slider 4 is slidably connected to the upper side wall of each sliding column 3. A pressing assembly 5 is located inside the slider 4. An oil pump 6, an oil tank assembly 7, and a control valve 8 are located on the top side of the pressing assembly 5. The oil pump 6 is located on the side wall of the control valve 8, and the oil tank assembly 7 is located at the connection point of the oil pump 6 and the control valve 8. A feeding platform 9 is provided on the left side of the pressing platform 2, and a feeding assembly 10 is provided at the bottom of the feeding platform 9. A discharge platform 11 is provided on the right side of the pressing platform 2. The driving structure at the bottom of the discharge platform 11 is the same as that of the feeding assembly 10. A control panel 12 is provided on the front side of the pressing platform 2. A base 13 is provided at the bottom of the pressing platform 2. A support frame 14 is provided below the feeding platform 9 and the discharge platform 11. A pressure sensor 15 is provided on the left side of the pressing platform 2 and is located to the right of the feeding platform 9.

[0023] like Figure 1As shown, the support assembly 1 includes a bracket 101 and a top beam 102. The pressing platform 2 is located at the lower end of the side wall of the bracket 101. The oil pump 6, the oil tank assembly 7, and the control valve 8 are located on the top side of the top beam 102. The top end of the pressing assembly 5 passes through the axis of the top beam 102 to its bottom. The top beam 102 is located at the top end of the bracket 101.

[0024] like Figure 4 As shown, the pressing assembly 5 includes a hydraulic cylinder 501 and a pressing block 502. The bottom end of the hydraulic cylinder 501 is fixedly connected to the top end of the pressing block 502. Under the pressure of hydraulic oil, the piston rod of the hydraulic cylinder 501 drives the pressing block 502 to move downward. The slider 4 slides down synchronously along the four sliding columns 3. The pressing block 502 applies pressure to the material on the pressing table 2.

[0025] like Figure 3 As shown, the oil tank assembly 7 includes an oil tank body 701 and a pipeline 702. The oil pump 6 is located on the side wall of the pipeline 702, and the control valve 8 is located at the connection point of the oil pump 6 and the pipeline 702. The pipeline 702 is located at the bottom left side of the oil tank body 701. The oil pump 6 draws hydraulic oil from the oil tank body 701 and delivers the hydraulic oil to the control valve 8 through the pipeline 702. The control valve 8 regulates the flow direction, pressure and flow rate of the hydraulic oil according to a preset program.

[0026] like Figure 5 As shown, the feeding assembly 10 includes a linear motor 1001 and a telescopic rod 1002. The output end of the linear motor 1001 is movably connected to the left end of the telescopic rod 1002. The top outer side of the telescopic rod 1002 is fixedly connected to the bottom of the feeding table 9. The linear motor 1001 serves as the power source of the feeding assembly 10 and starts to operate according to a preset command. The output end of the linear motor 1001 pushes the telescopic rod 1002 to move to the right, thereby driving the feeding table 9 to move horizontally to the right.

[0027] Working principle: such as Figures 1-5 As shown, during the feeding stage: the operator presets the feeding parameters on the control panel 12 and starts the equipment. The linear motor 1001, as the power source of the feeding component 10, starts to run according to the preset instructions. The output end of the linear motor 1001 pushes the telescopic rod 1002 to move to the right, thereby driving the feeding table 9 to move to the right. The material to be processed on the feeding table 9 is then accurately conveyed to the top of the pressing table 2. The pressure sensor 15 monitors the material on the pressing table 2 in real time. When the material is detected to be in place, the sensor sends a signal back to the control panel 12. The control system then controls the linear motor 1001 to stop working, completing the automatic and accurate feeding.

[0028] Pressing stage: After the material is successfully fed, the operator sets the pressing pressure, stroke and other parameters on the control panel 12. The control system issues a command, and the oil pump 6 starts to work. The oil pump 6 draws hydraulic oil from the oil tank body 701 and delivers the hydraulic oil to the control valve 8 through the pipeline 702. The control valve 8 regulates the flow direction, pressure and flow rate of the hydraulic oil according to the preset program, and delivers the regulated hydraulic oil to the hydraulic cylinder 501. Under the pressure of the hydraulic oil, the piston rod of the hydraulic cylinder 501 drives the pressing block 502 to move downward. The slider 4 slides down synchronously along the four sliding columns 3. The pressing block 502 applies pressure to the material on the pressing table 2 to realize the pressing operation.

[0029] Discharge stage: After pressing is completed, the control system sends a reverse command to the control valve 8 to change the flow direction of the hydraulic oil. The hydraulic oil flows back to the oil tank body 701. The piston rod of the hydraulic cylinder 501 drives the pressing block 502 and the slider 4 to return upward. At the same time, the feeding component 10 at the bottom of the discharge platform 11 starts to work. The linear motor 1001 runs and pushes the telescopic rod 1002 to move to the left. The discharge platform 11 then moves to the left to remove the pressed material from the pressing platform 2, completing the discharge process.
