Description

Technical Field

[0001] The invention belongs to the technical field of forging forming, and in particular relates to a forging forming processing device. Background Art

[0002] Forging is an ancient and important process in metal processing. It deforms the metal by applying pressure to obtain the desired shape and performance. Hydraulic technology provides powerful and controllable force and pressure, which is very suitable for forging, a process that requires high energy density. The hydraulic system can accurately control the size and duration of the forging force to achieve a fine forging process. The progress of hydraulic technology, such as high-pressure hydraulic components and precision control systems, has promoted the continuous development and improvement of hydraulic forging equipment. The growing demand for high-performance materials has promoted the improvement of forging processes and forging equipment. Some high-strength, high-toughness, and high-temperature resistant alloy materials can only obtain the best organizational structure and mechanical properties through forging, which in turn puts higher requirements on forging equipment, such as greater forging force and more precise control.

[0003] The existing forging forming and processing devices still have many defects: the existing forging forming and processing devices generally use hydraulic presses to complete the forging of workpieces, and the vane pump is the core of the hydraulic system. During the long-term use of the existing vane pump, the vanes, as the key components of the vane pump, will cause the vanes to wear during long-term operation, which will gradually increase the gap between the vanes and the inner wall of the vane pump, resulting in increased internal leakage and decreased volumetric efficiency, which means that the actual output capacity of the pump is reduced, which ultimately affects the performance and life of the pump, and the operating noise of the pump will increase, affecting the working environment; in addition, due to the complex shape of the forgings and uneven force, the degree of plastic deformation of different parts is often different, and the area with a large degree of deformation will produce greater internal stress. The existing forging forming and processing devices can only further process the workpiece after the forging is completed, which is time-consuming and labor-intensive. If it is not processed, it will cause cracks in the forging, reduce the fatigue strength of the workpiece and affect the plastic deformation ability of the forging. Summary of the invention

[0008] Preferably, two vertical plates are fixedly connected to the upper surface of the base plate, and a first rotating rod, a second rotating rod, and a third rotating rod are movably sleeved on one side of the vertical plate and are evenly distributed.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The present invention uses the design of the first gear, the second gear and the annular rack so that when the output end of the motor rotates, the first gear is driven to rotate, and the first gear drives the second gear to rotate. Under the action of the annular rack, the second gear rotates on itself and revolves around the first gear. The second gear drives the rotor to rotate synchronously through the fixed rod. The speed transmitted to the rotor by the output end of the motor is reduced, and the torque is increased, so that the tangential force on the blade is relatively reduced, the relative sliding speed between the blade and the inner wall of the vane pump is reduced, and the friction between the blade and the inner wall of the vane pump is relatively reduced, which greatly extends the service life of the blade and also improves the volumetric efficiency and overall efficiency of the pump, reduces the operating temperature to avoid excessive degradation of the oil, and improves the noise problem caused by friction.

[0014] 2. The present invention sets a resonance mechanism so that when the hydraulic column moves the forging downward, the hydraulic column drives the guide table, the buffer plate, and the buffer column to move downward. Since the buffer plate first contacts the mold platform and generates a downward force on it, the second spring is compressed at this time, and the notch at the lower end of the circular column acts on the lower end protrusion of the third linkage block. Under the action of the third rotating rod, the upper end protrusion of the third linkage block also meshes with the upper end of the circular column. Under the action of the second linkage block and the third spring, the circular column is locked. When the hydraulic column contacts the workpiece, the linkage rod also acts on the lower end protrusion of the first linkage rod at the same time, and the second linkage block is deflected accordingly. Then, through the action of the fourth spring, the upper end protrusion of the third linkage block is separated from the upper end notch of the circular column. When the buffer plate leaves the surface of the workpiece, the second spring is released to cooperate with the hydraulic rod to achieve a vibration effect. Vibration can promote the adjustment of the microstructure inside the material, thereby more effectively releasing residual stress, improving the dimensional stability of the forging, and reducing the difficulty and scrap rate of subsequent processing.

[0026] Among them, an oil suction port 16 is provided on the upper surface of the vane pump 10, and a plurality of sliding grooves are provided on the outer edge of the rotor 13. A vane 17 is movably sleeved on the inner side of the sliding groove. One end of a circular rack 18 is fixedly connected to the inner wall of the vane pump 10. The first gear 12 is meshed with the three second gears 15. The outer edges of the three groups of second gears 15 are meshed with the inner tooth surfaces of the circular rack 18. The output end of the motor 11 drives the first gear 12 to rotate, and the first gear 12 drives the three second gears 15 to rotate. Under the action of the circular rack 18, the three second gears 15 realize the orbital motion around the first gear. The three second gears 15 drive the rotor 13 to rotate through the fixed rod 14. Due to the eccentric rotation of the rotor 13, the vanes 17 in the sliding grooves of the rotor 13 are thrown out. Through this planet-like mechanism design, the speed of the rotor transmitted by the output end of the motor 11 can be reduced without affecting the normal suction and discharge of hydraulic oil by the vane pump, and the torque becomes larger, thereby achieving the purpose of reducing blade wear.

[0027] Among them, the resonance mechanism includes a circular ring block 102, the upper surface of the base plate 101 is fixedly connected to the lower surface of the circular ring block 102, the upper surface of the base plate 101 is fixedly connected to one end of two second springs 103 located on the inner side of the circular ring block 102, the other ends of the two groups of second springs 103 are fixedly connected to the mold table 19, the lower surface of the mold table 19 is fixedly connected to a circular ring column 104, the inner side of the circular ring column 104 is movably sleeved with the second spring 103, the lower surface of the base plate 101 is fixedly connected to one end of a hydraulic rod 105, the other end of the hydraulic rod 105 is fixedly connected to the lower surface of the mold table 19, driving the hydraulic column 4 to descend, the hydraulic column 4 drives the guide table 3 to move downward, the guide table 3 drives the buffer plate 7 and the buffer column 5 and the linkage column 29 to move downward, when the buffer plate 7 acts on the workpiece surface, the mold table 19 is subjected to a downward force, the mold table 19 drives the circular ring column 104 and the hydraulic rod 105 to move downward, to achieve the fixation of the mold table 19 and the guidance and buffering of the hydraulic column 4.

[0028] Among them, two vertical plates 20 are fixedly connected to the upper surface of the bottom plate 101, and one side of the vertical plate 20 is movably sleeved with a uniformly distributed first rotating rod 21, a second rotating rod 22, and a third rotating rod 23, one end of the outer cylindrical surface of the first rotating rod 21 is fixedly connected to a first linkage block 24, one end of the outer cylindrical surface of the second rotating rod 22 is fixedly connected to a second linkage block 25, and one end of the outer cylindrical surface of the third rotating rod 23 is fixedly connected to a third linkage block 26, one end of the first linkage block 24 is fixedly connected to one end of a third spring 27, and the other end of the first linkage block 24 is fixedly connected to one end of a fourth spring 28, the other end of the third spring 27 is fixedly connected to one side of the second linkage block 25, and the other end of the fourth spring 28 is fixedly connected to one side of the third linkage block 26. When the mold table 19 moves downward, the notch of the circular column 104 acts on the lower end protrusion of the third linkage block 26, and under the action of the third rotating rod 23 , the upper protrusion of the third linkage block 26 also meshes with the upper notch of the circular ring column 104, and the third linkage block 26 drives the first linkage block 24 to deflect through the fourth spring 28, and the first linkage block 24 drives the second linkage block 25 to deflect through the third spring 27, so that the outer edge of the second linkage block 25 meshes with the upper outer edge of the third linkage block 26. At this time, under the action of the second spring 103, the resonance mechanism is realized to achieve locking. When the hydraulic column 4 contacts the workpiece to complete the forging, the linkage column 29 also acts on the first linkage block 24. Similarly, the first linkage block 24 is deflected. Under the action of the third spring 27 and the fourth spring 28, the upper protrusion of the third linkage block 26 is separated from the upper notch of the circular ring column 104. When the hydraulic column 4 and the buffer plate 7 leave the mold table 19, the second spring 103 cooperates with the hydraulic rod 105 to drive the mold table 19 to resonate, thereby releasing the stress on the workpiece.

[0031] Working principle:

[0032] When the equipment is operating normally, the motor 11 is driven, and the output end of the motor 11 drives the first gear 12 to rotate, and the first gear 12 drives the three second gears 15 to rotate. Under the action of the circular rack 18, the three second gears 15 realize the orbital motion around the first gear, and the three second gears 15 drive the rotor 13 to rotate through the fixed rod 14. Due to the eccentric rotation of the rotor 13, the blades 17 in the sliding groove of the rotor 13 are thrown out, and the suction and extrusion of the hydraulic oil are realized. Through the action of the first gear 12, the second gear 15 and the circular rack 18, the speed of the motor 11 is reduced and the torque of the rotor 13 is increased, thereby reducing the tangential force acting on the blades 17, and the friction of the blades 17 on the inner wall of the vane pump 10 is also reduced when the blades 17 extend out and rotate.

[0033] When the equipment forges the workpiece, the hydraulic column 4 is driven to descend, and the hydraulic column 4 drives the guide table 3 to move downward, and the guide table 3 drives the buffer plate 7, the buffer column 5 and the linkage column 29 to move downward. When the buffer plate 7 acts on the surface of the workpiece, the mold table 19 is subjected to a downward force, and the mold table 19 drives the annular column 104 and the hydraulic rod 105 to move downward. The notch of the annular column 104 acts on the lower end protrusion of the third linkage block 26. Under the action of the third rotating rod 23, the upper end protrusion of the third linkage block 26 also meshes with the upper end notch of the annular column 104. The third linkage block 26 drives the first linkage block 24 to deflect through the fourth spring 28. The first linkage block 24 is driven by the third The spring 27 drives the second linkage block 25 to deflect, so that the outer edge of the second linkage block 25 meshes with the outer edge of the upper end of the third linkage block 26. At this time, under the action of the second spring 103, the resonance mechanism is realized to achieve locking. When the hydraulic column 4 contacts the workpiece to complete the forging, the linkage column 29 also acts on the first linkage block 24. Similarly, the first linkage block 24 is deflected under the action of the third spring 27 and the fourth spring 28, and the upper end protrusion of the third linkage block 26 is separated from the upper end notch of the circular column 104. When the hydraulic column 4 and the buffer plate 7 leave the mold table 19, the second spring 103 cooperates with the hydraulic rod 105 to drive the mold table 19 to resonate, thereby releasing the stress on the workpiece.
