Description

Technical Field

[0001] The present invention relates to the technical field of top presses, and particularly to an oil-electric hybrid six-sided top press. Background Art

[0002] A six-sided top press is a key device for synthesizing superhard materials such as synthetic diamond single crystals, cultivated diamonds, and cubic boron nitride. Under high temperature and high pressure conditions, physical and chemical changes occur in relevant raw materials to form superhard materials. For example, in industrial production, synthetic diamonds synthesized by a six-sided top press can be used to manufacture cutting tools, drilling bits, etc., and are widely used in industries such as construction and machining. Existing six-sided top presses all adopt pure hydraulic drive, but the stop position accuracy of the hydraulic cylinder is low, with a stop position accuracy in the millimeter level, and the working efficiency is low. Under normal working conditions, the empty stroke forward time of a pure hydraulic drive press is 50 - 60 seconds, and the return stroke time is about 40 seconds, with a slow efficiency, which affects the production rate of the equipment. Therefore, the present application proposes an oil-electric hybrid six-sided top press. Summary of the Invention

[0003] The purpose of the present invention is to propose an oil-electric hybrid six-sided top press for the problems of low stop position accuracy and low working efficiency in the background art.

[0004] The technical solution of the present invention: An oil-electric hybrid six-sided top press includes a limiting mechanism and a hydraulic oil control mechanism located on one side of the limiting mechanism. The limiting mechanism includes a plurality of limiting seats, and a gear transmission mechanism is arranged at the top ends of the plurality of limiting seats;

[0005] The gear transmission mechanism includes a servo motor fixed to the top end of the limiting mechanism, and a driving structure is arranged at the output end of the servo motor;

[0006] A top pressing mechanism is arranged at the central positions of the plurality of limiting seats.

[0007] Optionally, the driving structure includes a transmission rod fixed to the output end of the servo motor. A transmission gear is fixedly connected to the outer wall of the transmission rod through a sleeve. The outer wall of the transmission gear is in transmission connection with a plurality of driven gears. A threaded rod penetrates through one side of each of the plurality of driven gears. A transmission seat is threadedly connected to the outer wall of each of the plurality of threaded rods, and a through seat penetrates through the outer wall of each of the plurality of threaded rods. A connecting seat is fixedly connected to the bottom end of each of the plurality of transmission seats.

[0008] Optionally, a driving rod is fixedly connected to the bottom end of the transmission rod, and a top pushing rod is threadedly connected to the bottom end of the driving rod.

[0009] Optionally, the number of the plurality of the limiting seats is four, and the plurality of the limiting seats are opposite to each other in pairs. Inner limiting grooves are formed at the tops of the plurality of the limiting seats, and limiting sliders are slidably connected to the inner walls of the plurality of the inner limiting grooves. Sliding columns are fixedly connected to the tops of the plurality of the limiting sliders.

[0010] Optionally, one side of the outer wall of each of the plurality of the sliding columns is fixedly connected with a fixing plate, and ejector rods are fixedly connected to one side of the plurality of the fixing plates. All the ejector rods are located on the same axis.

[0011] Optionally, the pressing mechanism includes a base fixed at the center of gravity position of the limiting mechanism. A plurality of connecting bottom rods are fixedly connected to the outer wall of the base, and buffer blocks are fixedly connected to the ends of the plurality of the connecting bottom rods away from the base.

[0014] Compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0015] The present invention uses a gear transmission mechanism to efficiently convert the rotational motion of a servo motor into the linear motion of a hydraulic rod. With the precise rotation control ability of the servo motor, not only can the stop position accuracy of the hydraulic rod be accurately controlled, but also the forward movement during the idle stroke can quickly reach the position, greatly shortening the forward movement time and the return time during the idle stroke. This optimization significantly improves the production efficiency of the press and increases the output. At the same time, compared with the traditional purely hydraulic-driven press, the energy consumption of this device is greatly reduced, and the volume is also significantly reduced, effectively improving the economy and space utilization rate of the equipment.

[0029] Embodiment 1

[0030] Such as Figure 1 、 Figure 4 And Figure 5As shown in the figure, the oil-electric hybrid six-sided top press proposed by the present invention includes a limiting mechanism 3 and a hydraulic oil control mechanism 1 located on one side of the limiting mechanism 3. The limiting mechanism 3 includes a plurality of limiting seats 31. A gear transmission mechanism 2 is arranged at the top ends of the plurality of limiting seats 31. The gear transmission mechanism 2 includes a servo motor 21 fixed to the top end of the limiting mechanism 3. A driving structure is arranged at the output end of the servo motor 21. By setting the servo motor 21, the driving structure can obtain power to drive the equipment. The driving structure includes a transmission rod 22 fixed to the output end of the servo motor 21. A transmission gear 23 is fixedly connected to the outer wall of the transmission rod 22 through a sleeve. A plurality of driven gears 24 are drivingly connected to the outer wall of the transmission gear 23. A threaded rod 26 penetrates through one side of the plurality of driven gears 24. A transmission seat 27 is threadedly connected to the outer walls of the plurality of threaded rods 26. And the outer walls of the plurality of threaded rods 26 all penetrate through a through seat 25. A connecting seat 28 is fixedly connected to the bottom ends of the plurality of transmission seats 27. A driving rod 29 is fixedly connected to the bottom end of the transmission rod 22. A top push rod 210 is threadedly connected to the bottom end of the driving rod 29. By setting the servo motor 21 to drive the transmission rod 22 to rotate, the transmission rod 22 can drive the transmission gear 23 fixedly connected through the sleeve to rotate. The transmission gear 23 drives a plurality of driven gears 24 meshed on the outer wall to rotate. While the plurality of driven gears 24 are rotating, the threaded rods 26 penetrating through one side of the plurality of driven gears 24 rotate. Through the rotation of the plurality of threaded rods 26, the transmission seat 27 and the connecting seat 28 fixed to the bottom end of the transmission seat 27 slide, so as to drive the limiting mechanism 3 on one side to slide, thereby realizing the quick in-place of the idle stroke forward and the return stroke.

[0031] It should be additionally described that, as Figure 1 and Figure 4 shown, the number of the plurality of limiting seats 31 is four, and the plurality of limiting seats 31 are opposite to each other in pairs. Inner limiting grooves 32 are opened at the top ends of the plurality of limiting seats 31. And limiting sliders 33 are slidably connected to the inner walls of the plurality of inner limiting grooves 32. A sliding column 34 is fixedly connected to the top ends of the plurality of limiting sliders 33. A fixing plate 35 is fixedly connected to one side of the outer walls of the plurality of sliding columns 34. A top rod 36 is fixedly connected to one side of the plurality of fixing plates 35. The plurality of top rods 36 are all on the same axis. Through the opened inner limiting grooves 32, the sliding columns 34 fixed to the bottom end of the connecting seat 28 are limited and slide through the limiting sliders 33 at the bottom end. Through the fixing plates 35 fixed to one side of the outer walls of the plurality of sliding columns 34, the top rods 36 fixed to one side of the fixing plates 35 can slide.

[0032] In addition, as Figure 1 、 Figure 2 、 Figure 3 and Figure 6As shown, a pressing mechanism 4 is arranged at the central positions of a plurality of limiting seats 31. The pressing mechanism 4 includes a base 41 fixed at the central position of the limiting mechanism 3. By arranging the base 41, the base 41 can be supported and fixed, facilitating subsequent operations. A plurality of connecting bottom rods 42 are fixedly connected to the outer wall of the base 41. By arranging the connecting bottom rods 42, the pressing mechanism 4 arranged at the top of the base 41 is fixed more firmly. One ends of the plurality of connecting bottom rods 42 away from the base 41 are fixedly connected with buffer blocks 43. A push rod 44 penetrates through one side of the plurality of buffer blocks 43. By arranging the buffer blocks 43, when the push rod 44 is pushed to slide forward, a buffer is obtained between the fixing plate 35 and the pressing frame 411, preventing workpiece damage. One ends of the plurality of push rods 44 are slidably connected with hydraulic rods 45, and the other ends of the plurality of push rods 44 are fixedly connected with hydraulic oil chambers 46. By arranging the hydraulic oil chambers 46, after the device pushes the hydraulic oil chamber 46 to slide to the pressing position through the ejector rod 36, hydraulic oil is injected into the hydraulic oil chamber 46 through the hydraulic oil control mechanism 1. Hydraulic oil is injected into the push rod 44 through the hydraulic oil chamber 46, and the push rod 44 is used to push the hydraulic rod 45 to slide. One ends of the plurality of hydraulic rods 45 away from the push rods 44 are fixedly connected with a connecting pipe seat 47 through a hydraulic rod interface 49. The connecting pipe seat 47 seals the internal hydraulic oil to prevent oil leakage. The outer walls of the hydraulic rods 45 all penetrate through a pressing frame 411. By arranging the pressing frame 411, during internal processing, it is prevented that the material breaks and affects the outside. One ends of the plurality of connecting pipe seats 47 away from the hydraulic rods 45 are fixedly connected with a connecting flange seat 48. The inner walls of the connecting flange seat 48 are all threadedly connected with pressing hammers 410. By arranging the pressing hammers 410, the device can press-process the material through the pressing hammers 410.

[0033] In this embodiment, a servo motor 21 is provided to drive a transmission rod 22 to rotate, so that the transmission rod 22 drives a transmission gear 23 fixedly connected to a through sleeve to rotate. The transmission gear 23 drives a plurality of driven gears 24 meshed on the outer wall to rotate, so that the plurality of driven gears 24 drive a threaded rod 26 to rotate. Through the rotation of the plurality of threaded rods 26, a transmission seat 27 and a connecting seat 28 fixed to the bottom end of the transmission seat 27 slide. When the shaft of the servo motor 21 rotates one week, it drives a sliding column 34 and a push rod 36 fixed to one side of the sliding column 34 to move forward or backward. Through the drive of the servo motor 21, a position adjustment at the millimeter level can be achieved. Through an internal limit groove 32 formed in a limit seat 31, the sliding column 34 fixed to the bottom end of the connecting seat 28 is limited to slide through a limit slider 33 at the bottom end. Through a fixing plate 35 fixed to one side of the outer wall of the plurality of sliding columns 34, the push rod 36 can move forward. After the push rod 36 pushes the hydraulic oil chamber 46 to slide to the top pressure position, the hydraulic oil control mechanism 1 fills the hydraulic oil chamber 46 with hydraulic oil. The hydraulic oil chamber 46 fills the push rod 44 with hydraulic oil. The push rod 44 pushes a hydraulic rod 45 to slide. The hydraulic rod 45 drives a top pressure hammer head 410 to slide inward to perform top pressure processing on the internal material. By providing a buffer block 43, when the push rod 44 is pushed to slide forward, a buffer is obtained between the fixing plate 35 and a top pressure frame 411 to prevent workpiece damage.

[0034] The above specific embodiments are only several alternative embodiments of the present invention.
