Description

Technical Field

[0001] The invention relates to the technical field of ceramic processing, and in particular to a high-strength ultra-thin ceramic shell manufacturing device. Background Art

[0002] Industrial ceramics are ceramics widely used in industrial production and industrial products. It is a kind of fine ceramics, which can play mechanical, thermal, chemical and other functions in application. Since industrial ceramics usually have a series of advantages such as high temperature resistance, corrosion resistance, and wear resistance, industrial ceramics can better replace metal materials and organic polymer materials in emerging fields such as energy, aerospace, automobiles, and electronics in certain fields and working environments, and have very broad application prospects. Ceramic shells are a typical application of industrial ceramics. Ceramic shells are usually produced by ceramic powder pressing and molding. The Chinese invention patent application with publication number CN115871080A discloses a ceramic material powder processing pressing and molding device. The prior art is provided with a die mechanism, so that the die plate and the die bottom cooperate to extrude the ceramic powder, so that the ceramic powder can be pressed into a ceramic powder block, achieving the effect of rapid automatic die molding. However, the prior art cannot realize fully automatic ceramic powder filling and the discharge of the ceramic embryo shell after molding, as well as the automatic pressing of ceramic powder. Summary of the invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: a high-strength ultra-thin ceramic shell manufacturing device, including a main device, the main device including a bottom box, a slide rail is fixedly installed on the bottom box, the main device is provided with a powder feeding device and a moving device, the powder feeding device includes a discharge box, the discharge box is fixedly installed on the bottom box, the moving device includes a pressing mold and a side guide sleeve, the side guide sleeve is slidably installed on the slide rail, the main device is used to drive the moving device to move, the powder feeding device is used to put ceramic powder into the moving device, the main device is provided with a stamping device, the stamping device includes a stamping frame, the stamping frame is fixedly installed on the bottom box, and the stamping device is used to stamp the ceramic powder in the moving device.

[0004] The powder feeding device is filled with ceramic powder, which is then put into the moving device through the powder feeding device. The moving device moves the ceramic powder to the bottom of the stamping device, and the stamping device stamps the ceramic powder in the moving device into shape. The formed ceramic powder then leaves the device, and the stamped powder is then sintered to finally obtain a high-strength ultra-thin ceramic shell.

[0005] Furthermore, the main device includes a bottom motor fixedly mounted on the bottom box, a motor wheel fixedly mounted on the motor shaft of the bottom motor, a bidirectional screw rod rotatably mounted on the bottom box, a screw wheel fixedly mounted on the bidirectional screw rod, a transmission belt wrapped around the screw wheel and the motor wheel, a long track, an inner track and an outer track fixedly mounted on the bottom box, and a discharging mechanism is arranged on the bottom box.

[0006] Furthermore, the discharging mechanism comprises a rotating column fixedly mounted on the bottom box, an inner rotating column rotatably mounted on the rotating column, a rotating column gear and a rotating blade fixedly mounted on the inner rotating column, and a discharging slope fixedly mounted on the bottom box.

[0007] The rotation of the bottom motor drives the motor wheel to rotate, thereby driving the screw wheel to rotate through the transmission belt, thereby driving the bidirectional screw to rotate, driving the internal thread sleeve to slide, thereby driving the side guide sleeve to slide along the slide rail, thereby driving the pressing mold to move.

[0008] Furthermore, the feeding device includes a slide column fixedly mounted on the discharge box, a bottom switch plate is slidably mounted on the slide column, the bottom switch plate and the discharge box are slidably mounted, and a spring is arranged between the discharge box and the bottom switch plate.

[0009] Ceramic powder is placed in the discharge box and located on the bottom switch plate. When the pressing die begins to contact the bottom switch plate, it will push the bottom switch plate to slide along the sliding column, the spring is stretched, and the ceramic powder in the discharge box falls between the pressing die and the inner block. When the pressing die leaves the bottom switch plate, the bottom switch plate is reset under the action of the spring.

[0010] The moving device includes an internal thread sleeve fixedly installed on the pressing mold, an internal thread is arranged in the internal thread sleeve, the internal thread sleeve and the bidirectional screw form a threaded transmission, a fan blade rack is fixedly installed on the side of the pressing mold, an inner block is fixedly installed on the pressing mold, an ejection frame is slidably installed between the pressing mold and the inner block, a horizontal frame is fixedly installed on the ejection frame, a sliding ejector column is slidably installed in the horizontal frame, and an ejection spring is arranged between the ejection frame and the pressing mold.

[0011] In its initial state, the die is located below the discharge box, and the ceramic powder enters between the inner block and the die. Then the die leaves the discharge box, and the bottom switch plate rebounds under the action of the spring. At this time, a small amount of powder may remain on the surface of the die. As the die continues to move toward the stamping frame, when the fan blade rack engages with the rotating column gear, the fan blade rack slides and drives the rotating column gear to rotate, thereby driving the inner rotating column to rotate clockwise relative to the rotating column, so that the excess ceramic powder on the die is swept off by the rotating blade.

[0012] When the die moves toward the stamping frame, the sliding ejector column is pushed by the inner track to slide outward along the cross frame. The sliding ejector column is located on the long track at this time. When the die reaches under the stamping device, the stamping device stamps the ceramic powder between the die and the inner block, and then the die slides along the slide rail toward the discharge box. Under the action of the long track, the long track lifts the sliding ejector column and the screw wheel upward, and the ejection spring is compressed, and the pressed ceramic is ejected out of the die and the inner block through the ejection frame. When the fan blade rack engages with the rotating column gear, the fan blade rack drives the rotating blade to rotate counterclockwise, thereby pushing the ceramic into the discharge slope through the rotating blade. The ceramic slides out of the device through the discharge slope, and the die moves forward while the rotating blade rotates, ensuring that the formed ceramic can be pushed onto the discharge slope. Then the ceramic that slides out of the discharge slope is sintered to obtain a ceramic shell.

[0013] As the die continues to move toward the discharge box, the sliding top column is pushed by the outer track, and the sliding top column slides inward along the cross frame. At this time, the sliding top column is no longer on the long track. Then, as the die moves toward the stamping frame with the ceramic powder, the sliding top column will not be pushed upward under the action of the long track.

[0014] Furthermore, the stamping device comprises a stamping electric cylinder fixedly mounted on the stamping frame, and a stamping head is fixedly mounted on the top of the stamping electric cylinder.

[0015] When the pressing die reaches below the punch head, the punch electric cylinder extends to drive the punch head down, and the ceramic powder between the pressing die and the inner block is punched and formed.

[0016] Compared with the prior art, the present invention has the following advantages: (1) the powder feeding device provided in the present invention can cooperate with the moving device to automatically pour ceramic powder into the space between the pressing die and the inner block, and at the same time remove excess ceramic powder on the surface of the pressing die through the rotating blade; (2) after the ceramic powder is stamped, the moving device provided in the present invention drives the ejection frame through the long track to eject the stamped embryo shell, making it easier for the rotating blade to push the ceramic embryo shell out of the device; (3) the cooperation of the powder feeding device, the moving device and the stamping device provided in the present invention realizes the automatic pressing of ceramic powder, and the whole process is fully automatic with a high degree of automation.

DETAILED DESCRIPTION

[0028] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] Example: Reference Figure 1-Figure 10A high-strength ultra-thin ceramic shell manufacturing device includes a main device, the main device includes a bottom box 101, a slide rail 107 is fixedly installed on the bottom box 101, a powder feeding device and a moving device are arranged on the main device, the powder feeding device includes a discharge box 201, the discharge box 201 is fixedly installed on the bottom box 101, the moving device includes a pressing mold 301 and a side guide sleeve 304, the side guide sleeve 304 is slidably installed on the slide rail 107, the main device is used to drive the moving device to move, the powder feeding device is used to put ceramic powder into the moving device, and a stamping device is arranged on the main device, the stamping device includes a stamping frame 401, the stamping frame 401 is fixedly installed on the bottom box 101, and the stamping device is used to stamp the ceramic powder in the moving device.

[0030] The powder feeding device is filled with ceramic powder, which is then put into the moving device through the powder feeding device. The moving device moves the ceramic powder to the bottom of the stamping device, and the stamping device stamps the ceramic powder in the moving device into shape. The formed ceramic powder then leaves the device, and the stamped powder is then sintered to finally obtain a high-strength ultra-thin ceramic shell.

[0031] like Figure 1-Figure 5 As shown, the main device includes a bottom motor 102 fixedly mounted on the bottom box 101, a motor wheel 103 is fixedly mounted on the motor shaft of the bottom motor 102, a bidirectional screw rod 106 is rotatably mounted on the bottom box 101, a screw wheel 105 is fixedly mounted on the bidirectional screw rod 106, a transmission belt 104 is wound around the screw wheel 105 and the motor wheel 103, a long rail 113, an inner rail 114 and an outer rail 115 are fixedly mounted on the bottom box 101, and a discharging mechanism is arranged on the bottom box 101.

[0032] like Figure 2-Figure 5 As shown, the discharging mechanism includes a rotating column 108 fixedly mounted on the bottom box 101, an inner rotating column 109 is rotatably mounted on the rotating column 108, a rotating column gear 110 and a rotating blade 111 are fixedly mounted on the inner rotating column 109, and a discharging slope 112 is fixedly mounted on the bottom box 101.

[0033] The bottom motor 102 rotates to drive the motor wheel 103 to rotate, thereby driving the screw wheel 105 to rotate through the transmission belt 104, thereby driving the bidirectional screw 106 to rotate, driving the internal threaded sleeve 303 to slide, thereby driving the side guide sleeve 304 to slide along the slide rail 107, thereby driving the pressing mold 301 to move.

[0034] like Figure 6 As shown, the feeding device includes a slide column 202 fixedly mounted on the discharge box 201, a bottom switch plate 203 is slidably mounted on the slide column 202, the bottom switch plate 203 is slidably mounted with the discharge box 201, and a spring 204 is arranged between the discharge box 201 and the bottom switch plate 203.

[0035] Ceramic powder is placed in the discharge box 201, and the ceramic powder is located on the bottom switch plate 203. When the pressing mold 301 begins to contact the bottom switch plate 203, it will push the bottom switch plate 203 to slide along the sliding column 202, the spring 204 is stretched, and the ceramic powder in the discharge box 201 falls between the pressing mold 301 and the inner block 309. When the pressing mold 301 leaves the bottom switch plate 203, the bottom switch plate 203 is reset under the action of the spring 204.

[0036] like Figure 7-Figure 9 As shown, the moving device includes an internal threaded sleeve 303 fixedly mounted on the pressing mold 301, an internal thread is arranged inside the internal threaded sleeve 303, the internal threaded sleeve 303 and the bidirectional screw rod 106 form a threaded transmission, a fan blade rack 302 is fixedly mounted on the side of the pressing mold 301, an inner block 309 is fixedly mounted on the pressing mold 301, an ejection frame 305 is slidably mounted between the pressing mold 301 and the inner block 309, a cross frame 307 is fixedly mounted on the ejection frame 305, a sliding ejector column 308 is slidably mounted in the cross frame 307, and an ejection spring 306 is arranged between the ejection frame 305 and the pressing mold 301.

[0037] In its initial state, the die 301 is located below the discharge box 201, and the ceramic powder enters between the inner block 309 and the die 301. Then, the die 301 leaves the discharge box 201, and the bottom switch plate 203 rebounds under the action of the spring 204. At this time, a small amount of powder may remain on the surface of the die 301. As the die 301 continues to move toward the stamping frame 401, when the fan blade rack 302 engages with the rotating column gear 110, the fan blade rack 302 slides and drives the rotating column gear 110 to rotate, thereby driving the inner rotating column 109 to rotate clockwise relative to the rotating column 108, so that the excess ceramic powder on the die 301 is swept off by the rotating blade 111.

[0038] When the die 301 moves toward the punching frame 401, the inner rail 114 pushes the sliding top column 308 to slide outward along the horizontal frame 307. The sliding top column 308 is located on the long rail 113 at this time. When the die 301 reaches the bottom of the punching device, the punching device punches the ceramic powder between the die 301 and the inner block 309. Then, the die 301 slides along the slide rail 107 toward the discharge box 201. Under the action of the long rail 113, the long rail 113 pushes the sliding top column 308 and the screw wheel 105 upward. The ejection spring 306 is compressed, and the pressed ceramic is ejected out of the pressing mold 301 and the inner block 309 through the ejection frame 305. When the fan blade rack 302 is engaged with the rotating column gear 110, the fan blade rack 302 drives the rotating blade 111 to rotate counterclockwise, thereby pushing the ceramic to the discharge slope 112 through the rotating blade 111. The ceramic slides out of the device through the discharge slope 112. The pressing mold 301 moves forward while the rotating blade 111 rotates, ensuring that the formed ceramic can be pushed onto the discharge slope 112. The ceramic that slides out of the discharge slope 112 is then sintered to obtain a ceramic shell.

[0039] As the pressing mold 301 continues to move toward the discharge box 201, the sliding top column 308 is pushed by the outer track 115, and the sliding top column 308 slides inward along the cross frame 307. At this time, the sliding top column 308 is no longer located on the long track 113. Then, as the pressing mold 301 moves toward the stamping frame 401 with the ceramic powder, the sliding top column 308 will not be pushed upward under the action of the long track 113.

[0040] like Fig.10 As shown, the stamping device includes a stamping electric cylinder 402 fixedly mounted on a stamping frame 401 , and a stamping head 403 is fixedly mounted on the top of the stamping electric cylinder 402 .

[0041] When the pressing die 301 reaches below the punch head 403 , the punching electric cylinder 402 extends to drive the punch head 403 to descend, thereby punching and forming the ceramic powder between the pressing die 301 and the inner block 309 .

[0042] The working principle of the high-strength ultra-thin ceramic shell manufacturing device disclosed in the present invention is as follows: the bottom motor 102 rotates to drive the motor wheel 103 to rotate, thereby driving the screw wheel 105 to rotate through the transmission belt 104, thereby driving the bidirectional screw 106 to rotate, driving the internal thread sleeve 303 to slide, thereby driving the side guide sleeve 304 to slide along the slide rail 107, thereby driving the pressing mold 301 to move. Ceramic powder is placed in the discharge box 201, and the ceramic powder is located on the bottom switch plate 203. When the pressing mold 301 starts to contact the bottom switch plate 203, it will push the bottom switch plate 203 to slide along the slide column 202, the spring 204 is stretched, and the ceramic powder in the discharge box 201 falls between the pressing mold 301 and the inner block 309. When the pressing mold 301 leaves the bottom switch plate 203, the bottom switch plate 203 is reset under the action of the spring 204. In its initial state, the die 301 is located below the discharge box 201, and the ceramic powder enters between the inner block 309 and the die 301. Then, the die 301 leaves the discharge box 201, and the bottom switch plate 203 rebounds under the action of the spring 204. At this time, a small amount of powder may remain on the surface of the die 301. As the die 301 continues to move toward the stamping frame 401, when the fan blade rack 302 engages with the rotating column gear 110, the fan blade rack 302 slides and drives the rotating column gear 110 to rotate, thereby driving the inner rotating column 109 to rotate clockwise relative to the rotating column 108, so that the excess ceramic powder on the die 301 is swept off by the rotating blade 111. When the die 301 moves toward the stamping frame 401, the inner rail 114 pushes the sliding top column 308 to slide outward along the horizontal frame 307. The sliding top column 308 is now located on the long rail 113. When the die 301 reaches the bottom of the stamping device, the stamping electric cylinder 402 extends to drive the stamping head 403 to descend, and the ceramic powder between the die 301 and the inner block 309 is stamped and formed. Then the die 301 slides along the slide rail 107 toward the discharge box 201. Under the action of the long rail 113, the long rail 113 pushes the sliding top column 308 and the screw wheel 105 is pushed upward, the ejection spring 306 is compressed, and the pressed ceramic is ejected out of the pressing mold 301 and the inner block 309 through the ejection frame 305. When the fan blade rack 302 is engaged with the rotating column gear 110, the fan blade rack 302 drives the rotating blade 111 to rotate counterclockwise, so that the rotating blade 111 pushes the ceramic to the discharge slope 112. The ceramic slides out of the device through the discharge slope 112. The pressing mold 301 moves forward while the rotating blade 111 rotates to ensure that the formed ceramic can be pushed onto the discharge slope 112. The ceramic that slides out of the discharge slope 112 is then sintered to obtain a ceramic shell.As the pressing mold 301 continues to move toward the discharge box 201, the sliding top column 308 is pushed by the outer track 115, and the sliding top column 308 slides inward along the cross frame 307. At this time, the sliding top column 308 is no longer located on the long track 113. Then, as the pressing mold 301 moves toward the stamping frame 401 with the ceramic powder, the sliding top column 308 will not be pushed upward under the action of the long track 113.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope of the present invention, which should be covered by the protection scope of the present invention.
