Abstract

This invention belongs to the technical field of six-sided top press machines and discloses a six-sided top press machine with an outer frame, including a six-sided top press machine body. The six-sided top press machine body is provided with a protective part, which includes a frame plate frame that is fixedly connected to the bottom outer wall of the six-sided top press machine body.

Description

Technical Field

[0001] This invention belongs to the field of six-sided top press technology, specifically a six-sided top press with an outer frame. Background Technology

[0002] Six-sided top presses are divided into hinged type and tie rod type. The hinged type six-sided top press is the most widely used large-cavity press in China. This type of press has the advantages of simple high-pressure mold structure, low cost and easy operation. It is a commonly used equipment for synthesizing superhard materials such as diamond and cubic boron nitride in China. It generates high pressure by hydraulically driving six cemented carbide top hammers to extrude the synthetic material, and generates high temperature by heating with low voltage and high power current, so that the internal structure of the synthetic material undergoes a qualitative change to form a new superhard material.

[0003] Currently, the six-sided top press operates under high pressure and high temperature. The pumps, valves and other components of the hydraulic system, as well as the overall operation of the equipment, generate significant noise and vibration. This not only poses a threat to the hearing health of the operators, but may also affect the stability and accuracy of the equipment. Long-term exposure to noise and vibration may also accelerate the wear and aging of the equipment. Summary of the Invention

[0004] To address the problems mentioned in the background section, the present invention provides a six-sided top press with an outer frame.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a six-sided top press with an outer frame, comprising a six-sided top press body, a protective part provided on the six-sided top press body, the protective part including a frame plate fixedly connected to the bottom outer wall of the six-sided top press body, heat insulation frame plates fixedly connected to both sides of the frame plate, and telescopic electric cylinders and telescopic rods fixedly connected to the other two sides of the frame plate, respectively; large U-shaped connecting plates are jointly fixedly connected to the outer walls at both ends of the telescopic electric cylinder and the telescopic rod; and the telescopic electric cylinder and the telescopic rod... Each component is also fixedly connected to a sleeve rod, and each sleeve rod is equipped with a folded soundproof and fireproof plate, which is used to reduce noise and block the heat emitted by the six-sided top press body during operation. Both folded soundproof and fireproof plates are also equipped with a tension buffer structure, which is used to buffer the vibration of the six-sided top press body during operation. Furthermore, the telescopic electric cylinder and telescopic rod column are also equipped with clamping structures that can abut against the outer walls of the two ends of the six-sided top press body near the bottom. The limiting effect of the clamping structures at both ends can make the operation of the six-sided top press body more stable.

[0006] Each of the two aforementioned tension buffer structures includes a telescopic sleeve plate. A cylindrical groove is provided on one end of the telescopic sleeve plate. A T-shaped rubber plate is slidably connected to the inner wall of the cylindrical groove. One end of the outer wall of the T-shaped rubber plate and one end of the outer wall of the six-sided top press body can be intermittently slidably attached. A spring is fixedly connected between one end of the outer wall of the telescopic sleeve plate and the other end of the outer wall of the T-shaped rubber plate.

[0007] Small U-shaped connecting plates are fixedly connected to the outer walls on both sides of one end of the folding soundproof and fireproof board. The outer wall of one end of the small U-shaped connecting plate is fixedly connected to the outer wall of the telescopic sleeve plate near the top. The outer wall of the bottom end of the telescopic sleeve plate is fixedly connected to the outer wall of the frame.

[0008] The clamping structure includes a toothed plate that is fixedly connected to one end of the telescopic electric cylinder and the telescopic rod, and each toothed plate is intermittently meshed with a spur gear, and the spur gear is provided with a synchronous belt.

[0009] Preferably, a T-shaped slider is fixedly connected to one end of each of the sleeve rods, and a rubber ball is fixedly connected to the bottom outer wall of one of the T-shaped sliders. The bottom outer wall of the folded soundproof and fireproof board is fixedly connected to the outer wall of one end of the frame. A T-shaped groove is provided on the top end of the folded soundproof and fireproof board to slide and fit with the T-shaped slider, and a ball groove is also provided at the bottom end of the T-shaped groove to indirectly engage with the rubber ball.

[0010] Preferably, abutments are fixedly connected to the inner walls of both sides of the top of the frame, and the bottom ends of the two abutments are intermittently connected to the top outer walls of the two folded soundproof and fireproof boards.

[0011] Preferably, one end of the synchronous belt is fixedly connected to one end of the outer wall of the spur gear, and a screw is fixedly connected through the spur gear. The screw is also fixedly connected through the one end of the synchronous belt.

[0012] Preferably, a guide rod is fixedly connected through to the other side of the synchronous belt, and a double-ring positioning rod is movably sleeved on one side of the screw and the guide rod. The bottom end of the double-ring positioning rod is fixedly connected to the outer wall of the frame.

[0013] Preferably, a sliding plate is also provided on one side of the screw and the guide rod, the screw and the sliding plate are connected by a thread, and the guide rod and the sliding plate are connected by a sliding connection.

[0014] Preferably, a sliding plate is fixedly connected to one side of the guide rod, and a clamping plate is fixedly connected to one end of the sliding plate.

[0015] Preferably, the inner wall of one end of the clamping plate and the side wall of the six-sided top press body near the bottom can be intermittently fitted and connected, and the plate body of the part of the clamping plate that contacts the six-sided top press body is made of natural rubber.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention uses a telescopic electric cylinder to move the sleeve rod and the folding soundproof and fireproof board upwards simultaneously. The upward-moving folding soundproof and fireproof board gradually stretches and expands passively until it contacts the abutment plate installed on the frame. At this point, the folding soundproof and fireproof board is blocked from moving upwards, but the sleeve rod continues to move upwards, causing the connected T-shaped slider and rubber ball to disengage from the ball groove's locking limit. Under the influence of gravity and the abutment plate, the folding soundproof and fireproof board passively moves downwards a certain distance after being passively unfolded, giving it a wave-like shape. The resulting ripple effect effectively improves noise reduction. While the folding soundproof and fireproof board itself reduces noise, it also significantly enhances the noise reduction effect.

[0018] This invention utilizes the passive upward movement of the folded soundproof and fireproof board, which simultaneously drives the telescopic sleeve plate connected by the small U-shaped connecting plate upward. This upward movement of the telescopic sleeve plate causes the T-shaped rubber plate to gradually contact one end of the outer wall of the six-sided top press body. Simultaneously, the rubber material of the T-shaped rubber plate is squeezed by the six-sided top press body during this upward movement. The squeezed T-shaped rubber plate slides within the cylindrical groove, simultaneously compressing the spring and causing it to deform. The T-shaped rubber plate in contact with the six-sided top press body, along with the spring installed on it, can buffer some of the vibrations generated during the operation of the six-sided top press body, improving its stability during operation, preventing loosening of equipment parts due to long-term vibration, and extending the service life of the six-sided top press body.

[0019] When the invention is initiated by the telescopic electric cylinder, it can also simultaneously move the toothed plate upwards until the passively moving toothed plate contacts and engages with the spur gear, causing the spur gear to rotate. The rotating spur gear will simultaneously drive the timing belt to rotate, and the rotating timing belt will simultaneously drive the screw and guide rod to rotate at a fixed point on the double-ring positioning rod. The rotating screw will drive the sliding plate to move horizontally with the help of the guide rod. The sliding plate will drive the fixedly connected moving plate to move synchronously, thereby causing the clamping plate to move horizontally to contact and clamp the six-sided top press body, pressing against the bottom of the six-sided top press body. The rubber material of one section of the clamping plate will play a vibration buffering effect after clamping and pressing the six-sided top press body, thus achieving a two-stage buffering effect, making the buffering effect better and more effective.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 8As shown, the present invention provides a six-sided top press with an outer frame, including a six-sided top press body 1. A protective part 2 is provided on the six-sided top press body 1. The protective part 2 includes a frame plate 21 fixedly connected to the bottom outer wall of the six-sided top press body 1. Heat-insulating frame plates 22 are fixedly connected to both sides of the frame plate 21. Telescopic electric cylinders 23 and telescopic rods 24 are fixedly connected to the other two sides of the frame plate 21, respectively. Large U-shaped connecting plates 2401 are jointly fixedly connected to the outer walls of both ends of the telescopic electric cylinders 23 and the telescopic rods 24. The telescopic electric cylinders 23 and the telescopic rods 24 also have... The six-sided top press body 1 is fixedly connected with sleeve rods 25, and each sleeve rod 25 is equipped with a folded sound insulation and fireproof plate 28, which is used to reduce noise and block the heat emitted during operation. Both folded sound insulation and fireproof plates 28 are also equipped with a tension buffer structure, which is used to buffer the vibration of the six-sided top press body 1 during operation. The telescopic electric cylinder 23 and the telescopic rod column 24 are also equipped with clamping structures that can abut against the outer walls of the two ends near the bottom of the six-sided top press body 1. The limiting effect of the clamping structure at both ends can make the operation of the six-sided top press body 1 more stable.

[0033] Each sleeve rod 25 has a T-shaped slider 26 fixedly connected to one end. A rubber ball 27 is fixedly connected to the bottom outer wall of the T-shaped slider 26. The bottom outer wall of the folded soundproof and fireproof board 28 is fixedly connected to the outer wall of one end of the frame 21. The top end of the folded soundproof and fireproof board 28 has a T-shaped groove 29 that slides and fits with the T-shaped slider 26. The bottom end of the T-shaped groove 29 also has a ball groove 230 that can indirectly engage with the rubber ball 27.

[0034] The above solution involves activating the telescopic electric cylinder 23 to move the sleeve rod 25 and the folded soundproof and fireproof board 28 upwards simultaneously. The upward-moving folded soundproof and fireproof board 28 will gradually be passively stretched and expanded until it passively contacts the abutment plate 2801 installed on the frame 21. At this point, the folded soundproof and fireproof board 28 will be blocked from moving upwards, while the sleeve rod 25 will continue to move upwards, causing the connected T-shaped slider 26 and rubber ball 27 to disengage from the locking limit of the ball groove 230. Under the influence of gravity and the abutment plate 2801, the folded soundproof and fireproof board 28 will passively move downwards a certain distance after being passively unfolded, giving it a wave-like shape. The ripple effect produced by this wave-like shape effectively improves the noise reduction effect. While the folded soundproof and fireproof board 28 itself can reduce noise, this also greatly enhances its beneficial noise reduction effect.

[0035] Each of the two tension buffer structures includes a telescopic sleeve plate 232. A cylindrical groove 233 is provided on one end of the telescopic sleeve plate 232. A T-shaped rubber plate 234 is slidably connected in the inner wall of the cylindrical groove 233. One end of the outer wall of the T-shaped rubber plate 234 and one end of the outer wall of the six-sided top press body 1 can be intermittently slidably attached. A spring 235 is fixedly connected between one end of the outer wall of the telescopic sleeve plate 232 and the other end of the outer wall of the T-shaped rubber plate 234.

[0036] Abutment plates 2801 are fixedly connected to the inner walls of the top two sides of the frame 21. The bottom ends of the two abutment plates 2801 are intermittently connected to the top outer walls of the two folded soundproof and fireproof boards 28. Small U-shaped connecting plates 231 are fixedly connected to the outer walls of the two sides of one end of the folded soundproof and fireproof board 28. The outer wall of one end of the small U-shaped connecting plate 231 is fixedly connected to the outer wall of the telescopic sleeve plate 232 near the top. The outer wall of the bottom end of the telescopic sleeve plate 232 is fixedly connected to the outer wall of the frame 21.

[0037] The above solution involves the passive upward movement of the folded soundproof and fireproof board 28, which simultaneously drives the telescopic sleeve 232 connected by the small U-shaped connecting plate 231 to move upward. The upward movement of the telescopic sleeve 232 causes the T-shaped rubber plate 234 to gradually contact one end of the outer wall of the six-sided top press body 1. At the same time, the rubber material of the T-shaped rubber plate 234 is squeezed by the six-sided top press body 1 during the upward movement. The squeezed T-shaped rubber plate 234 slides in the cylindrical groove 233 and simultaneously squeezes the spring 235, causing it to deform. The T-shaped rubber plate 234 in contact with the six-sided top press body 1 and the spring 235 installed on the T-shaped rubber plate 234 can buffer some of the vibrations generated when the six-sided top press body 1 is operating, improve the stability of the six-sided top press body 1 during operation, avoid the loosening of equipment parts under long-term vibration, and extend the service life of the six-sided top press body 1.

[0038] The clamping structure includes a toothed plate 236 fixedly connected to one end of the telescopic electric cylinder 23 and the telescopic rod 24. Each toothed plate 236 is intermittently meshed with a spur gear 237. The spur gear 237 is equipped with a synchronous belt 238. One side wall of the synchronous belt 238 is fixedly connected to one outer wall of the spur gear 237. A screw 239 is fixedly connected through the spur gear 237. The screw 239 is also fixedly connected through the side wall of the synchronous belt 238. A guide rod 240 is fixedly connected through the other side of the synchronous belt 238. A double-ring positioning rod is movably sleeved on one side of the screw 239 and the guide rod 240. 241. The bottom end of the double-ring positioning rod 241 is fixedly connected to the outer wall of the frame plate 21. A sliding plate 242 is also provided on one side of the screw 239 and the guide rod 240. The screw 239 and the sliding plate 242 are connected by a thread, and the guide rod 240 and the sliding plate 242 are connected by a sliding connection. A moving plate 243 is also fixedly connected to one side of the guide rod 240. A clamping plate 244 is fixedly connected to one side wall of the moving plate 243. The inner wall of one end of the clamping plate 244 can be intermittently fitted and connected to the side wall of the six-sided top press body 1 near the bottom. The plate at the contact point between the clamping plate 244 and the six-sided top press body 1 is made of natural rubber.

[0039] The above scheme is adopted: when the telescopic electric cylinder 23 starts to move upward, it can also drive the toothed plate 236 to move upward simultaneously until the passively moving toothed plate 236 contacts and engages with the spur gear 237, driving the spur gear 237 to rotate. The rotating spur gear 237 will drive the synchronous belt 238 to rotate and transmit power. The synchronous belt 238 driven by this transmission will simultaneously drive the screw 239 and the guide rod 240 to rotate at a fixed point on the double ring positioning rod 241. The rotating screw 239 will drive the slide plate 242 to move horizontally with the help of the guide rod 240. The sliding plate 242 will drive the fixedly connected moving plate 243 to move synchronously. This will cause the clamping plate 244 to move horizontally and contact the six-sided top press body 1 to press against the bottom of the six-sided top press body 1. The rubber material of a section of the clamping plate 244 will play a vibration buffering effect after clamping and pressing the six-sided top press body 1, thus achieving a two-stage buffering effect, making the buffering effect better and more effective.

[0040] One point that needs to be added is that the upward movement of the telescopic electric cylinder 23 will synchronously drive the large U-shaped connecting plate 2401 to move upward. The large U-shaped connecting plate 2401 drives the connected telescopic rod 24 to move upward and extend the rod body, thereby achieving synchronous movement. This allows the telescopic rod 24 and the telescopic electric cylinder 23 to indirectly drive the moving plate 243 and the clamping plate 244 to move in opposite directions, achieving synchronous translation, pressing, and clamping of the outer walls at both ends of the six-sided top press body 1.

[0041] The working principle and usage process of this invention are as follows: The telescopic electric cylinder 23 drives the sleeve rod 25 and the folded soundproof and fireproof board 28 to move upwards simultaneously. As a result, the folded soundproof and fireproof board 28 gradually stretches and expands passively until it contacts the abutment plate 2801 installed on the frame 21. At this point, the folded soundproof and fireproof board 28 is blocked from moving upwards, while the sleeve rod 25 continues to move upwards, causing the connected T-shaped slider 26 and rubber ball 27 to disengage from the locking limit of the ball groove 230. Under the influence of gravity and the abutment plate 2801, the folded soundproof and fireproof board 28 passively unfolds and then moves downwards a certain distance, creating a wave-like shape. The resulting ripple effect effectively improves noise reduction. While the folded soundproof and fireproof board 28 itself reduces noise, it also significantly enhances the noise reduction effect. The beneficial effects are that during the passive upward movement of the folding soundproof and fireproof board 28, the telescopic sleeve 232 connected by the small U-shaped connecting plate 231 will also move upward. The upward movement of the telescopic sleeve 232 will cause the T-shaped rubber plate 234 to gradually contact the outer wall of one end of the six-sided top press body 1. At the same time, the rubber material of the T-shaped rubber plate 234 will be squeezed by the six-sided top press body 1 during the upward movement. The squeezed T-shaped rubber plate 234 will slide in the cylindrical groove 233 and will also squeeze the spring 235 at the same time, causing it to deform. The T-shaped rubber plate 234 in contact with the six-sided top press body 1 and the spring 235 installed on the T-shaped rubber plate 234 can buffer some of the vibrations generated when the six-sided top press body 1 is operating, improve the stability of the six-sided top press body 1 during operation, avoid the loosening of equipment parts under long-term vibration, and extend the service life of the six-sided top press body 1.

[0042] At the same time, when the telescopic electric cylinder 23 starts to move upward, it can also drive the toothed plate 236 to move upward until the passively moving toothed plate 236 contacts and meshes with the spur gear 237, driving the spur gear 237 to rotate. The rotating spur gear 237 will drive the synchronous belt 238 to rotate and transmit power. The synchronous belt 238 driven by this transmission will simultaneously drive the screw 239 and the guide rod 240 to rotate at a fixed point on the double ring positioning rod 241. The rotating screw 239 will drive the slide plate 242 to move horizontally with the help of the guide rod 240. The sliding plate 242 will drive the fixedly connected moving plate 243 to move synchronously. This will cause the clamping plate 244 to move horizontally and contact the six-sided top press body 1 to press against the bottom of the six-sided top press body 1. The rubber material of a section of the clamping plate 244 will play a vibration buffering effect after clamping and pressing the six-sided top press body 1, thus achieving a secondary buffering effect, making the buffering effect better and more effective.
