Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hydraulic presses, and specifically relates to a hydraulic press with a novel oil cylinder structure driving a sliding block to move rapidly. Background Art
[0002] In the existing four-column hydraulic press, the oil inlet in the upper chamber of the oil cylinder pushes the piston rod downward and connects to the slide block through the oil cylinder, so that the slide block moves downward. Hydraulic presses are mostly used in processes such as thin plate stretching and hot forming. During the processing, when the upper mold is pressed onto the workpiece, the load force is low, so the pressure required to press the slide block downward is small. Since the oil enters the oil cylinder more stably, its downward speed is relatively fixed. If you want to speed up the slide block downward speed and improve production efficiency, you can only speed up the slide block downward speed by increasing the main oil flow or the number of oil pumps. Increasing the flow and the number of oil pumps requires increasing the motor power, and increasing the diameter of each control valve core and pipeline, which increases the cost, resulting in energy waste and increased use costs.
[0003] When processing various products, the existing hydraulic presses require different pressures for different parts. Processing on the same press depends on adjusting the pressure of the press fluid to set the required machine pressure. When the pressure is reduced, the area of the oil cylinder does not change, that is, the pressing speed does not change randomly. Therefore, if you want to speed up the pressing speed, you have to increase the flow rate of the oil, the number of oil pumps, and the power of the motor, which increases the cost of use.
[0004] To this end, we proposed a hydraulic press with a new type of cylinder structure that drives the slider to move quickly. It not only increases the main oil flow, oil pump and motor power to increase the slider's downward pressure speed, but also effectively reduces production costs and improves production efficiency. This structure is simple, easy to install and suitable for popularization and use. Utility Model Content

The third solenoid valve 26 is connected to a hydraulically controlled one-way valve 7 and a second oil tank 8. One side of the fourth solenoid valve 24 is connected to a fifth solenoid valve 30, a sixth solenoid valve 32 and a seventh solenoid valve 34. The seventh solenoid valve 34 is connected to the third solenoid valve 26.
[0028] Furthermore, the oil cylinder body 1 is used to allow oil to enter, and at the same time, the piston rod 2 can drive the main engine slider 37 to move.
[0029] Furthermore, a guide column 3 connected to the piston rod 2 is provided inside the cylinder body 1, and the piston rod 2 is guided by the guide column 3 to prevent deviation.
[0030] Furthermore, oil enters through the first oil connection port 5 , the second oil connection port 6 and the third oil connection port 38 .

When the oil cylinder moves downward, the volume of the piston rod 2 chamber is reduced, the sixth solenoid valve 32 and the seventh solenoid valve 34 are charged, and the oil flows into the oil tank through the sixth valve core 33 and the seventh valve core 35, completing a downward pressure action.
[0037] When the main engine slider 37 moves upward, the fourth solenoid valve 24 and the first solenoid valve 28 have the first valve core 27 closed, the fourth valve core 25 opened, the main oil pump 29 enters the piston rod cavity through the third connecting oil port 38 to push the piston rod 2 to move upward, the oil cylinder piston cavity is discharged, the eighth solenoid valve 13 and the third solenoid valve 26 are electrically opened, the hydraulically controlled one-way valve 7 and the ninth valve core 12 discharge oil to the oil tank to form a reciprocating motion, the first pressure regulating valve 19 adjusts the required pressure, and the main oil pump 29 oil enters the piston cavity through the first connecting oil port 5. Since the guide column 3 fixes the oil and pushes the piston rod 2 to move downward, the main engine slider 37 moves downward rapidly with the oil cylinder piston rod 2. This device not only increases the main oil flow rate, oil pump and motor power, but also increases the slider pressing speed, while effectively reducing production costs and improving production efficiency. This structure is simple, easy to install and suitable for popularization and use.
