Description

Technical Field

[0001] This invention relates to the field of corundum ceramic preparation technology, and in particular to a device for preparing wear-resistant multiphase corundum ceramic. Background Technology

[0002] White fused alumina is a ceramic material with high hardness, high strength, and high wear resistance. It is sintered and processed at high temperatures to form shaped ceramics. The process of making ceramics with white fused alumina involves steps such as raw material preparation, forming, drying, sintering, and surface treatment. In the ceramic forming step, workers need to put the raw material into a specific mold and then press it into shape. During the forming process, workers need to manually pour the white fused alumina raw material into the mold and manually remove it after forming. During this process, workers are often injured.

[0003] To address the problems existing in the above-mentioned prior art, we have designed a safer and more durable multiphase corundum ceramic preparation device. Summary of the Invention

[0004] This invention provides a highly safe apparatus for preparing wear-resistant multiphase corundum ceramics, overcoming the shortcomings of the prior art mentioned in the background section, which often results in operator injuries.

[0005] The technical solution of the present invention is as follows: a wear-resistant multiphase corundum ceramic preparation device, comprising a base, a support frame fixedly connected to the base, a guide frame fixedly connected to the base, the guide frame being located between the support frames, a pressing frame slidably connected to the guide frame, a pull rod fixedly connected to the pressing frame, a base plate slidably connected inside the pressing frame, a hydraulic rod installed on the support frame, a pressing mold connected to the hydraulic rod, the pressing mold cooperating with the pressing frame to press the corundum ceramic, an infrared-sensing emergency stop device provided on the side of the support frame near the hydraulic rod, the infrared-sensing emergency stop device being electrically connected to the hydraulic rod, a sensor fixedly connected to the pressing frame, and an inductive switch provided on the side of the base near the pressing frame, the inductive switch being electrically connected to the hydraulic rod.

[0006] Furthermore, it is particularly preferred that the inductive switch and the sensor are located on the same horizontal line, and that the inductive switch cooperates with the sensor.

[0007] Furthermore, it is particularly preferred that the base is equipped with a vibration motor.

[0008] Furthermore, it is particularly preferred that the assembly also includes a lifting component for easy removal of the formed ceramic. The lifting component is disposed on the base and includes a top frame. The top frame is slidably connected to the side of the base near the bottom plate. The top frame is located between the bottom plate and the base. The base is fixedly connected to a first fixing block. The first fixing block is rotatably connected to a rotating plate. The side of the base near the top frame is fixedly connected to a guide block. The rotating plate is slidably connected to the guide block.

[0009] Furthermore, it is particularly preferred that the guide block has a vertical groove, the lowest point of which is horizontally lower than the lowest point of the first fixing block.

[0010] Furthermore, it is particularly preferred that the base also includes a counterweight assembly for controlling the quality of raw materials. The counterweight assembly is disposed on the base and includes a sliding groove. The sliding groove is disposed on the side of the base near the bottom plate. A force-bearing frame is slidably connected to the sliding groove. The force-bearing frame is fixedly connected to the bottom plate. A first spring is connected between the force-bearing frame and the base.

[0011] Furthermore, it is particularly preferred that the base has a protrusion on the side near the slide groove, and the protrusion of the base cooperates with the slide groove to limit the position of the force-bearing frame.

[0012] Furthermore, it is particularly preferred that the device also includes an adsorption component for ensuring the stability of the pressing frame. The adsorption component is disposed on the pressing frame and includes a first magnet fixed to the pressing frame. A second magnet is fixed to the side of the base near the pressing frame, and the first magnet and the second magnet are adsorbed together.

[0013] Furthermore, it is particularly preferred that the device also includes a blocking component to ensure the safety of pressing. The blocking component is disposed between the pressing mold and the base. The blocking component includes a second fixing block fixed to the base and the pressing mold. The second fixing block of the pressing mold is rotatably connected to an upper connecting plate, and the second fixing block of the base is rotatably connected to a lower connecting plate. A connecting rod is rotatably connected between the upper connecting plate and the lower connecting plate on the same side and adjacent to each other.

[0014] Furthermore, it is particularly preferred that the device also includes a leak-proof component to prevent material leakage during feeding. The leak-proof component is disposed on the connecting rod and the upper connecting plate. The leak-proof component includes a third fixing block, which is fixedly connected to the upper connecting plate near the pull rod. A guide rod is fixedly connected to the side of the third fixing block near the pull rod. A fourth fixing block is slidably connected to the side of the guide rod away from the third fixing block. A second spring is connected between the third fixing block and the fourth fixing block. A U-shaped frame is fixedly connected to the fourth fixing block. The U-shaped frame is rotatably connected to the connecting rod near the pull rod.

[0015] Compared with existing technologies, the advantages of this invention are as follows: The infrared-sensing emergency stop device controls the hydraulic rod to stop suddenly, ensuring operator safety and preventing injury; the forward movement of the pressing frame drives the top frame forward, which in turn drives the bottom plate upward to extrude the ceramic, facilitating ceramic removal and effectively saving manpower; the first spring's action allows the force-bearing frame to cooperate with the chute, precisely distributing the raw materials to ensure the ceramic preparation effect and avoid weight deviations that could lead to quality deviations in the final ceramic product; when the vibrating motor vibrates, the first and second magnets attract energy... It ensures the accuracy of the pressing frame's position, preventing relative displacement between the pressing frame and the pressing mold, which would affect the pressing effect. The connecting rod moves outwards, and the upper and lower connecting plates fold into a triangle, preventing operators from getting too close and ensuring their safety, thus avoiding accidental injury during the pressing process. The U-shaped frame smooths the material inside the pressing frame as it moves backwards, preventing material overflow during pressing and affecting the final product. The U-shaped frame also acts as a shield to prevent material spillage, ensuring that when material falls into the pressing frame, it doesn't spill onto the base, causing instability in the pressing frame or support frame.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0026] Example 1: A device for preparing wear-resistant multiphase corundum ceramics, see below. Figures 1-3 As shown, the device includes a base 1, a support frame 2 fixedly connected to the base 1, a guide frame 3 fixedly connected to the base 1, the guide frame 3 being located between the support frames 2, a pressing frame 4 slidably connected to the guide frame 3, a pull rod 401 fixedly connected to the front side of the pressing frame 4, a base plate 5 slidably connected inside the pressing frame 4, a hydraulic rod 7 mounted on the support frame 2, and a pressing mold 6 connected to the hydraulic rod 7. The pressing mold 6 cooperates with the pressing frame 4 to press corundum ceramic. A red... An infrared-sensing emergency stop device 8 is electrically connected to the hydraulic rod 7. A sensor 9 is fixedly connected to the rear right side of the pressing frame 4. An induction switch 10 is provided on the side of the base 1 near the pressing frame 4. The induction switch 10 is electrically connected to the hydraulic rod 7 and is used to control the opening of the hydraulic rod 7. The induction switch 10 and the sensor 9 are located on the same horizontal line and cooperate with each other. A vibration motor 11 is installed on the base 1.

[0027] When it is necessary to prepare corundum ceramics, this wear-resistant multiphase corundum ceramic preparation device can be used. The ceramic preparation raw material is placed in the pressing frame 4 on the base plate 5, and then the pull rod 401 is pushed backward, so that the pull rod 401 moves the pressing frame 4 backward to the bottom of the pressing mold 6. The backward movement of the pressing frame 4 moves the sensor 9 backward, so that the sensor 9 presses the induction switch 10. The induction switch 10 controls the hydraulic rod 7 to start, and the hydraulic rod 7 moves the pressing mold 6 downward, thereby pressing the ceramic preparation raw material in the pressing frame 4 into shape. During the downward movement of the hydraulic rod 7 and the pressing mold 6, if the operator's limbs are inside the pressing mold 6, there is a risk of being crushed. In this case, the infrared-sensing emergency stop device 8 protects the operator. If the infrared-sensing emergency stop device 8 senses a person's limbs during the start of the hydraulic rod 7, it will control the hydraulic rod 7 to stop moving through the control module. When the infrared-sensing emergency stop device 8 no longer senses a person's limbs, the hydraulic rod 7 will start again to press the ceramic preparation raw materials. In this way, the infrared-sensing emergency stop device 8 can ensure the operator's safety and prevent injury.

[0028] Example 2: Based on Example 1, see... Figures 4-5 As shown, it also includes a lifting assembly for easy removal of the formed ceramic. The lifting assembly is disposed on the base 1 and includes a top frame 12. The top frame 12 is slidably connected to the side of the base 1 near the bottom plate 5. The top frame 12 is located between the bottom plate 5 and the base 1. The base 1 is fixedly connected to a first fixing block 14. The first fixing block 14 is rotatably connected to a rotating plate 13. The rear side of the rotating plate 13 is inclined downward. The rear side of the base 1 is fixedly connected to a guide block 15. The rotating plate 13 and the guide block 15 are slidably connected. The guide block 15 has a vertical groove. The lowest point of the vertical groove is horizontally lower than the lowest point of the first fixing block 14.

[0029] To facilitate the removal of the ceramic after pressing, after pressing, the operator pulls the lever 401 forward, causing the lever 401 to move the pressing frame 4 forward, thereby moving the top frame 12 forward. The top frame 12 moves forward and upward along the rotating plate 13, thereby moving the bottom plate 5 upward. The upward movement of the bottom plate 5 extrudes the formed ceramic, making it easy for the operator to remove the ceramic. After the ceramic is removed, the operator pulls the lever 401 forward again, causing the lever 401 to move the pressing frame 4 to the foremost position, causing the top frame 12 to disengage from the rotating plate 13. This allows the top frame 12 to move downward under gravity, causing the bottom plate 5 to... As plate 5 moves downward, the operator can pour the raw material into the pressing frame 4 and then push the pull rod 401 backward. The pull rod 401 drives the pressing frame 4 to move backward, causing the bottom plate 5 to drive the top frame 12 to move backward. The top frame 12 is now located under the rotating plate 13. As the bottom plate 5 moves backward, the top frame 12 cannot move downward, so it will squeeze the rotating plate 13 to rotate, causing the rear side of the rotating plate 13 to slide on the guide block 15. When the top frame 12 moves backward and disengages from the rotating plate 13, the rotating plate 13 moves downward and resets under gravity. This process is repeated to automatically eject the pressed ceramic, effectively saving manpower.

[0030] Example 3: Based on Example 2, see... Figure 6 As shown, it also includes a counterweight assembly for controlling the quality of raw materials. The counterweight assembly is disposed on the base 1 and includes a slide groove 18. The slide groove 18 is disposed on the side of the base 1 near the bottom plate 5. A protrusion is disposed on the side of the base 1 near the slide groove 18. A force-bearing frame 16 is slidably connected to the slide groove 18. The protrusion of the base 1 cooperates with the slide groove 18 to limit the force-bearing frame 16. The force-bearing frame 16 is fixedly connected to the bottom plate 5. A first spring 17 is connected between the force-bearing frame 16 and the base 1.

[0031] Since mass-produced ceramics generally have a fixed quality, meaning the quality of raw materials used in each pressing is also fixed, quality differences are inevitable during actual operation, leading to quality deviations in the final ceramic product. To avoid weight deviations, when the pressing frame 4 moves the base plate 5 forward, it also moves the force-bearing frame 16 forward. The force-bearing frame 16 moves upward along with the base plate 5 during this forward movement, stretching the first spring 17. When the pressing frame 4 reaches its foremost position, the force-bearing frame 16 disengages from the base 1 and, under the reset action of the first spring 17, moves the base plate 5 upward, placing it in the lower part of the pressing frame 4 when there is no raw material. When raw material is added to the pressing frame 4, if the material is too heavy, it will cause weight deviations. The first spring 17 is excessively compressed by the raw material, the base plate 5, and the force-bearing frame 16, preventing the force-bearing frame 16 from engaging with the slide 18 and the protrusion of the base 1. Consequently, the operator cannot push the pressing frame 4 backward. If the raw material is too light, the compressive force on the first spring 17 from the raw material, the base plate 5, and the force-bearing frame 16 is small. The force-bearing frame 16, located above the slide 18, cannot engage with the slide 18 and the protrusion of the base 1, and the operator also cannot push the pressing frame 4 backward. Only when the weight of the raw material is just right will the force-bearing frame 16 engage with the slide 18 and the protrusion of the base 1. Thus, through the action of the first spring 17, the force-bearing frame 16 cooperates with the slide 18 to precisely balance the weight of the raw material, ensuring the effectiveness of ceramic preparation.

[0032] Example 4: Based on Example 3, see... Figure 6 As shown, it also includes an adsorption component for ensuring the stability of the pressing frame 4. The adsorption component is disposed on the pressing frame 4 and includes a first magnet 19, which is fixed to the rear side of the pressing frame 4. A second magnet 20 is fixed to the rear of the base 1, and the first magnet 19 and the second magnet 20 are adsorbed together.

[0033] To ensure the accuracy of the pressing, when the pressing frame 4 moves backward, it will drive the first magnet 19 to move backward. The first magnet 19 moves backward and attracts the second magnet 20. When the vibration motor 11 vibrates, the attraction between the first magnet 19 and the second magnet 20 can ensure the accuracy of the position of the pressing frame 4, and prevent the relative position of the pressing frame 4 and the pressing mold 6 from shifting, which would affect the pressing effect.

[0034] See Figure 7As shown, it also includes a blocking component to ensure the safety of pressing. The blocking component is disposed between the pressing mold 6 and the base 1. The blocking component includes a second fixing block 21 fixed to the base 1 and the pressing mold 6. The second fixing block 21 of the pressing mold 6 is rotatably connected to an upper connecting plate 22. The second fixing block 21 of the base 1 is rotatably connected to a lower connecting plate 23. A connecting rod 24 is rotatably connected between the upper connecting plate 22 and the lower connecting plate 23 on the same side and adjacent to each other.

[0035] To prevent operators from getting too close and being accidentally injured during the pressing process, when the hydraulic rod 7 moves the pressing mold 6 downward, the hinge point of the upper connecting plate 22 and the lower connecting plate 23 will move outward, causing the connecting rod 24 to move outward. The upper connecting plate 22 and the lower connecting plate 23 will fold into a triangle to prevent operators from getting too close and ensure their safety.

[0036] See Figure 8 As shown, it also includes a leak-proof component to prevent material leakage during feeding. The leak-proof component is disposed on the connecting rod 24 and the upper connecting plate 22. The leak-proof component includes a third fixing block 25, which is fixed to the upper connecting plate 22 on the front side. A guide rod 26 is fixed to the rear side of the third fixing block 25. A fourth fixing block 28 is slidably connected to the lower side of the guide rod 26. A second spring 27 is connected between the third fixing block 25 and the fourth fixing block 28. A U-shaped frame 29 is fixed to the fourth fixing block 28. The U-shaped frame 29 is rotatably connected to the connecting rod 24 on the front side.

[0037] To prevent raw materials from spilling onto the base 1 when falling into the pressing frame 4, causing instability in the pressing frame 4 or the force-bearing frame 16, the U-shaped frame 29 can be used to block the spillage. The U-shaped frame 29 can also smooth the raw materials inside the pressing frame 4 as it moves backward, preventing overflow during pressing and affecting the final product. When the pressing mold 6 moves downward to press, the U-shaped frame 29 moves outward with the connecting rod 24 and rotates adaptively, with the second spring 27 deforming accordingly. When the pressing mold 6 moves upward to reset, both the second spring 27 and the U-shaped frame 29 return to their original positions.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
