[0057] Sagger 011; main body 012; enclosing plate 013. Specific embodiments

[0058] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0059] The present invention relates to a full-automatic blank making device for saggers. In this embodiment, the sagger 011 blank (hereinafter referred to as sagger 011) made by the full-automatic blank making device has a box-like structure as shown in Figure 14 The sagger 011 in this example has a main body 012 and an enclosing plate 013. The main body 012 is rectangular, and the enclosing plate 013 extends perpendicularly from the four sides of the main body 012. A groove is provided in the middle of the enclosing plate 013. As shown in Figure 1As shown in the figure, the full-automatic billet-making equipment includes a weighing and feeding mechanism 100, a feeding mechanism 300, a first moving mechanism 400, a feeding supplement mechanism 700, and a billet-taking mechanism 500. The full-automatic billet-making equipment of the present invention is used in cooperation with an external module 200.

[0060] The weighing and feeding mechanism 100 is mainly used for quantitatively feeding the powder for making the sagger 011. As Figure 2 shown, in this embodiment, the weighing and feeding mechanism 100 includes a first belt conveyor 110, a first hopper 120, and a weight sensing component 130. The first hopper 120 has openings at both the top and bottom, and the powder is stored in the first hopper 120. The first hopper 120 is installed on the first belt conveyor 110. At the first hopper 120, it can be set to control the opening and closing of the lower opening of the first hopper 120 through a controllable moving gate. The lower port of the first hopper 120 is open, and the first material port is close to the belt surface of the first belt conveyor 110. When the first belt conveyor 110 operates, the powder at the lower port of the first hopper 120 is automatically carried away by the movement of the belt. The weight sensing component 130 can be set inside the first hopper 120; or as Figure 2 shown, the weight sensing component 130 is set below the first belt conveyor 110. A weight sensor is installed inside the weight sensing component 130, and the weight sensing component 130 senses the total weight of the first belt conveyor 110, the first hopper 120, and the powder stored therein in real time. The powder is transported to the subsequent process along with the first belt conveyor 110, so by detecting the weight difference before and after transportation, the start and stop of the first belt conveyor 110 can be controlled in real time to control the quantitative transportation of the powder.

[0061] In this embodiment, as Figure 3 、 Figure 5 shown, the external module 200 includes an upper die head 210 and a lower die 220 which are distributed vertically. In this embodiment, the lower die 220 is fixed, and the upper die head 210 moves up and down above the lower die 220. A hanging part 230 can be set on the upper die head 210, and the hanging part 230 can be, but is not limited to, in the shape of Figure 3The structure shown has a connecting rod 231 vertically extending downward on the side wall of the upper die head 210 and a round rod 232 horizontally connected to the connecting rod 231. The lower die 220 is provided with a die cavity 221, and the shape of the die cavity 221 is contoured to the shape of the sagger 011. The die cavity 221 is paired and designed according to the shape of the sagger 011. Among them, the periphery of the die cavity 221 is a downward-extending border 222, and the shape of this border 222 is paired with the border plate 013 of the sagger 011, that is, the border 222 of the die cavity 221 is used for forming the border plate 013 of the sagger 011. An ejecting assembly 240 is provided in the die cavity 221. The ejecting assembly 240 can be structures such as an ejecting plate or an ejecting column, and can be arranged at the middle part of the bottom surface of the die cavity 221, the four corners, etc. After the sagger 011 is pressed in the die cavity 221, the ejecting assembly 240 can be used to eject the sagger 011 upward to demold the sagger 011.

[0062] As Figure 6 shown, the first moving mechanism 400 is installed on the frame 401. The first moving mechanism 400 can be a transmission structure such as belt drive, chain drive, or gear drive in cooperation with a motor drive. The weighing and feeding mechanism 100 can be fixed on the frame 401 or can be installed above the first moving mechanism 400 through other supporting structures.

[0063] As Figure 6 、 Figure 7 shown, the feeding mechanism 300 includes a moving frame 310, a pressing frame 320, a locking assembly 330, and a cloth feeding assembly 340. The moving frame 310 is installed on the first moving mechanism 400, and the first moving mechanism 400 moves the moving frame 310 between the module 200 and the weighing and feeding mechanism 100. The cloth feeding assembly 340 is installed on the pressing frame 320, the pressing frame 320 is installed on the moving frame 310, and the pressing frame 320 together with the cloth feeding assembly 340 moves along with the moving frame 310. When the cloth feeding assembly 340 moves along with the moving frame 310, it drops materials into the inside of the die cavity 221 and the outer periphery of the die cavity 221. The outer periphery of the die cavity 221 is the end face of the lower die 220 surrounding the die cavity 221. Among them, the lower part of the pressing frame 320 is shaped to fit the border 222 of the die cavity 221, and the lower part of the pressing frame 320 can be inserted into the border 222 of the die cavity 221. The pressing frame 320 is slidably installed on the moving frame 310 and is locked and fixed on the moving frame 310 through the locking assembly 330. When the locking assembly 330 is unlocked, the pressing frame 320 can move up and down relative to the moving frame 310, and the cloth feeding assembly 340 moves up and down together with the pressing frame 320. A hook member 350 is provided on the pressing frame 320, and this hook member 350 cooperates with the hanging member 230. The hook member 350 can be hooked on the hanging member 230 or can be disengaged from the hanging member 230.

[0064] As Figure 5 andFigure 13 As shown in the figure, a feeding mechanism 700 is further provided on the lower die 220. The feeding mechanism 700 includes a push plate 710, a pushing cylinder 720, and a feeding frame 730. In this embodiment, when viewed from the top, the mold cavity 221 is rectangular, and the four push plates 710 are respectively distributed in a rectangular shape in the horizontal space, that is, the four push plates 710 are distributed around the four sides of the mold cavity 221. The four pushing cylinders 720 are respectively connected to the four push plates 710. During installation, the push plate 710 is horizontally attached to the upper end surface of the lower die 220. The feeding frame 730 is fixed on the lower die 220 and is located above the push plate 710. The feeding frame 730 is rectangular in shape, with openings at the top and bottom, and surrounds the mold cavity 221. The feeding frame 730 is used to surround the powder that falls outside the mold cavity 221 during the cloth feeding process of the cloth feeding assembly 340. During the compacting process, the pushing cylinder 720 is used to drive the push plate 710 to move, and the powder that falls around the mold cavity 221 is pushed into the mold cavity 221. In particular, the powder is pushed to the corresponding position of the surrounding edge 222 of the mold cavity 221, and then the upper die punch 210 is used for reciprocating compacting to ensure sufficient material at the surrounding plate 013 when the sagger 011 is formed.

[0065] As Figure 1 and Figure 8 shown in the figure, the blank taking mechanism 500 is located on the other side of the module 200 relative to the feeding mechanism 300. The blank taking mechanism 500 includes a second moving mechanism 510 and a clamping assembly 600. The second moving mechanism 510 can be selected from transmission structures such as belt drive, chain drive, and gear drive, which are cooperated with a motor drive. The clamping assembly 600 is connected to the second moving mechanism 510, and the second moving mechanism 510 drives the clamping assembly 600 to move back and forth inside and outside the module 200. Moreover, the blank taking mechanism 500 can be lifted on the second moving mechanism 510. Among them, the clamping assembly 600 includes four clamping hands 610, and the four clamping hands 610 are distributed in a rectangular shape in the horizontal space and can be telescopic. The distribution positions are matched with the main body 012 of the sagger 011.

[0066] When the full-automatic billet-making equipment is working, the powder for pressing the sagger 011 is stored in the first hopper 120. The first moving mechanism 400 drives the feeding mechanism 300 to move below the weighing and feeding mechanism 100. The first belt conveyor 110 operates to transport the powder in the first hopper 120 towards the feeding mechanism 300. The powder falls from the end of the first belt conveyor 110 into the cloth-feeding assembly 340. The weighing sensor continuously detects the weight difference before and after the powder falls. After the weight difference reaches the preset value (the amount for one sagger 011), the first belt conveyor 110 stops operating. Then the first moving mechanism 400 drives the feeding mechanism 300 to move into the module 200. The upper die pressure of the module 200 is in the rising state. The moving frame 310 drives the pressure frame 320 and the cloth-feeding assembly 340 to move above the mold cavity 221. During the moving-in process, the cloth-feeding assembly 340 starts to feed the powder into the mold cavity 221 until the pressure frame 320 is positioned directly above the mold cavity 221, and the cloth-feeding assembly 340 finishes feeding. Then the locking assembly 330 unlocks the pressure frame 320, and the pressure frame 320 and the cloth-feeding assembly 340 descend relative to the moving frame 310. The lower part of the pressure frame 320 inserts into the peripheral edge 222 of the mold cavity 221. The upper die punch 210 descends and abuts against the top of the pressure frame 320 to press down the pressure frame 320. The lower part of the pressure frame 320 further inserts downward into the peripheral edge 222, and a prototype of the peripheral plate 013 of the sagger 011 is pre-pressed in the peripheral edge 222 of the mold cavity 221. The pre-pressing effectively improves the density at the peripheral plate 013 of the sagger 011 after molding, especially at the four corners of the sagger 011. When the upper die punch 210 descends, the hanging part 230 descends with the upper die punch 210 to below the hook part 350. After pre-pressing, the upper die punch 210 rises, and the hook part 350 is hooked onto the hanging part 230. Through the hooking connection between the hook part 350 and the hanging part 230, the upper die punch 210 lifts the pressure frame 320 until the pressure frame 320 rises to the locking position on the moving frame 310. The locking assembly 330 is activated to lock the pressure frame 320 on the moving frame 310. The upper die punch 210 continues to rise, and the hook part 350 disengages from the hanging part 230. Then the moving frame 310 drives the pressure frame 320 and the cloth-feeding assembly 340 to leave the module 200. After the feeding mechanism 300 leaves the module 200, the upper die punch 210 descends into the mold cavity 221 to press the powder in the mold cavity 221. The upper die punch 210 rises and descends repeatedly for many times. Before the upper die punch 310 descends, the feeding supplement mechanism 700 pushes the powder outside the mold cavity 221 into the mold cavity 221 to supplement the powder at the peripheral edge 222 of the mold cavity 221, especially at the four corners, to ensure the amount of material at the peripheral plate 013 and the four corners of the sagger 011 to improve the density and ensure the quality. After the sagger 011 is molded, the jacking assembly 240 rises to push the sagger 011 upward out of the mold cavity 221 for demolding.The blank taking mechanism 500 is activated. The second moving mechanism 510 drives the clamping assembly 600 to move into the module 200. The clamping assembly 600 descends, and the four clamping hands 610 surround the sagger 011. The clamping hands 610 extend and clamp around the sagger 011. The clamping assembly 600 clamps the sagger 011 and ascends, and the second moving mechanism 510 drives the clamping assembly 600 to leave the module 200. Through the cooperation of the weighing and feeding mechanism 100, the module 200, the feeding mechanism 300, the first moving mechanism 400, and the blank taking mechanism 500, the full-automatic billet making equipment completes the processes of quantitative feeding, cloth laying, pre-pressing, billet pressing, material replenishment, demoulding, and unloading, with low manual participation and high production efficiency.

[0067] In this embodiment, as Figure 4 shown, the pressure frame 320 includes an upper frame body 321 and a lower frame body 322 which are connected in an up-and-down distribution. The top of the upper frame body 321 is open and the middle is hollowed out. The cloth laying assembly 340 is installed in the upper frame body 321. The powder material falls into the cloth laying assembly 340 from the top opening of the upper frame body 321. The discharging end of the cloth laying assembly 340 extends outside the upper frame body 321. The lower part of the lower frame body 322 is in a rectangular frame shape and cooperates with the surrounding edge 222 of the die cavity 221. The pressure frame 320 can be slidably connected to the moving frame 310 through a vertically arranged slide rail. In this embodiment, a number of rollers 354 are arranged on the moving frame 310, and the rollers 354 are distributed around the peripheral surface of the pressure frame 320. The curved surfaces of the rollers 354 rollingly abut against the peripheral side walls of the pressure frame 320. When the pressure frame 320 ascends and descends, the rollers 354 roll relative to the ascending and descending direction of the pressure frame 320, that is, the rollers 354 are used to limit the position of the pressure frame 320 in the front, back, left, and right directions to ensure the stable ascending and descending of the pressure frame 320 relative to the moving frame 310.

[0068] The locking assembly 330 can be selected from a pneumatic locking member or an electric locking member. In some specific embodiments of the present invention, as Figure 7As shown in the figure, the locking assembly 330 includes a locking cylinder 331, a positioning pin seat 332, and a position sensor 333. The locking cylinder 331 is horizontally fixed on the moving seat, and the positioning pin seat 332 is fixed on the blank holding frame 320. The positions of the positioning pin seat 332 and the locking cylinder 331 can be interchanged. The position sensor 333 is installed on the blank holding frame 320 and the moving frame 310, and can be fixed on the moving frame 310. The position sensor 333 can be a proximity switch, and the position sensor 333 is used to locate the locking position of the blank holding frame 320 relative to the moving frame 310. Under normal conditions, the telescopic end of the locking cylinder 331 extends and abuts against the inside of the positioning pin seat 332, thereby fixing the blank holding frame 320 on the moving frame 310. When the upper die punch 210 pre-presses the mold cavity 221 by using the blank holding frame 320, the telescopic end of the locking cylinder 331 contracts and moves away from the positioning pin seat 332, and the blank holding frame 320 can move up and down relative to the moving frame 310. When the upper die punch 210 drives the blank holding frame 320 to rise, the rising position of the blank holding frame 320 is detected by the position sensor 333, and the signal is fed back to the locking assembly 330, and the locking cylinder 331 extends again and abuts against the positioning pin seat 332 to lock. A plurality of locking assemblies 330 can be provided between the blank holding frame 320 and the moving seat.

[0069] In some specific embodiments of the present invention, such as Figure 3 and Figure 6As shown, the hanging member 230 can be installed on the side wall of the upper die punch 210. The hanging member 230 includes a connecting rod 231 extending downward and a circular tube horizontally installed on the connecting rod 231. Two hanging members 230 are symmetrically arranged on both sides of the upper die punch 210. The hook member 350 is arranged on the side wall of the blank holding frame 320. The hook member 350 extends upward, and the top of the hook member 350 is a hook portion 351. Two hook members 350 are respectively arranged on both sides of the blank holding frame 320. The hook member 350 can be in a long strip shape, and the top is a hook portion 351 bent toward the blank holding frame 320. The hook member 350 is rotatably connected to the side wall of the blank holding frame 320 through a first rotating shaft 353. The hook member 350 rotates around the first rotating shaft 353, and the rotation movement of the hook member 350 is a swing around the first rotating shaft 353 in the direction toward or away from the blank holding frame 320. A spring 352 is arranged between the hook member 350 and the blank holding frame 320. In this embodiment, the elastic force of the spring 352 on the hook member 350 is to pull the hook member 350 toward the blank holding frame 320. During operation, when the upper die punch 210 descends, the hanging member 230 first abuts against the top of the hook portion 351 during the descending process. The hanging member 230 slides relative to the top of the hook portion 351, which is equivalent to using the hanging member 230 to push the hook portion 351 outward until the hanging member 230 descends to a position lower than the hook portion 351. When the hanging member 230 rises with the upper die punch 210, the hook portion 351 is hooked on the hanging member 230, and the spring 352 ensures that the hook member 350 is stably hooked on the hanging member 230 toward the blank holding frame 320. When the locking assembly 330 locks and fixes the blank holding frame 320, the hanging member 230 continues to rise with the upper die punch 210. Under the upward pulling force of the upper die punch 210, the bottom surfaces of the hanging member 230 and the hook portion 351 slide relative to each other, which is equivalent to forcibly swinging the hook member 350 outward to disengage from the hanging member 230. The hanging and disengaging actions of the hanging member 230 and the hook member 350 are cleverly realized by using the swing of the hook member 350 and the action of the spring 352. In the present invention, the hanging member 230 or the hook member 350 can also be moved by an electric drive such as a motor or a cylinder to realize the hanging and disengaging actions.

[0070] In some specific embodiments of the present invention, such as Figure 7As shown in the figure, the fabric component 340 includes a second belt conveying mechanism 341 and a second hopper 342. The second hopper 342 has upper and lower openings and is installed above the second belt conveying mechanism 341. The conveying direction of the second belt conveying mechanism 341 is the direction in which the moving frame 310 enters the module 200. During the process of the moving frame 310 driving the fabric component 340 and the pressure frame 320 into the module 200 together, the second belt conveying mechanism 341 is started, and the powder in the second hopper 342 is fed into the mold cavity 221 by the movement of the belt. A baffle 343 is provided on the moving frame 310. The baffle 343 faces the conveying end of the second belt conveying mechanism 341. The baffle 343 has a certain blocking effect on the powder when it falls from the end of the second belt conveying mechanism 341, ensuring that the powder falls into the mold cavity 221.

[0071] In some specific embodiments of the present invention, the clamping component 600 further includes a rectangular installation frame 620. The installation frame 620 is horizontally placed, and four clamping hands 610 are respectively installed at the four corners of the installation frame 620. Each clamping hand 610 can be driven to expand and contract by a cylinder or a motor. The installation frame 620 is connected to the first moving mechanism 400 through a first lifting drive component. The first lifting drive component can be connected by a vertically arranged slide rail and a cylinder, and the installation frame 620 is driven by the cylinder to move up and down along the slide rail. Preferably, in order to cooperate with clamping the rectangular-shaped sagger 011, each clamping hand 610 is provided with two clamping fingers 611 distributed at right angles to each other, and each clamping hand 610 respectively corresponds to and cooperates with the four right angles of the sagger 011. The expansion and contraction direction of each clamping hand 610 is to move towards the center of the spatial rectangle formed by the four clamping hands 610.

[0072] In some embodiments of the present invention, as Figure 9 , Figure 10 shown, an oiling mechanism 800 is provided on the first moving mechanism 400. The oiling mechanism 800 includes a first brush member 810 and a second brush member 820. The first brush member 810 moves up and down on the first moving mechanism 400, and the second brush member 820 moves horizontally on the first moving mechanism 400. When the first moving mechanism 400 is reset, it drives the blank taking mechanism 500 and the oiling mechanism 800 to leave the module 200. Among them, when the oiling mechanism 800 enters the module 200 along with the blank taking mechanism 500, since the sagger 011 is located in the lower mold 220 and the upper mold press head 210 is in a vacant state, the first brush member 810 rises and abuts against the upper mold press head 210, and the lower surface of the upper mold press head 210 is smeared with a release agent as the connecting frame moves. When the oiling mechanism 800 leaves the module 200 along with the blank taking mechanism 500, the sagger 011 in the lower mold 220 is taken out. At this time, the first brush member 810 descends, and the upper surface of the mold cavity 221 of the lower mold 220 is smeared with a release agent as the connecting frame moves. Among them, the oiling process of the second brush member 820 is as follows:

[0073] 1. When the first moving mechanism 400 drives the second brushing member 820 to withdraw from the green compact mold, when the second brushing member 820 moves to a position opposite to the front end position of the mold cavity 221, the first moving mechanism 400 stops moving, and the second brushing member 820 moves horizontally left and right. The brushing surface of the second brushing member 820 abuts against the front end face of the mold cavity 221 and slides / rolls thereon to apply a release agent to the front end of the mold cavity 221;

[0074] 2. After the front end face of the mold cavity 221 is coated, the two second brushing members 820 are respectively reset, and the first moving mechanism 400 continues to withdraw. During the withdrawal process, the brushing surface of the second brushing member 820 abuts against the left and right side faces of the mold cavity 221, and while moving with the first moving mechanism 400, it applies a release agent to the left and right side faces of the mold cavity 221;

[0075] 3. Finally, when the first moving mechanism 400 drives the second brushing member 820 to move to a position corresponding to the rear end face of the mold cavity, the first moving mechanism 400 stops moving, and the second brushing member 820 moves horizontally left and right to apply a release agent to the rear end face of the mold cavity 221.

[0076] After the oiling mechanism 800 leaves the module 200 of the blank taking mechanism 500, it resets to the initial position. In this embodiment, the first brushing member 810 includes two first brush strips 811, the first brush strips 811 are horizontally arranged, and the two first brush strips 811 can be installed vertically through a connecting plate 812. The connecting plate 812 is connected to the first moving mechanism 400 through a second lifting drive assembly 813. The second lifting drive assembly 813 can be provided with a cylinder or a motor, and in cooperation with a vertically arranged slide rail, the cylinder drives the connecting plate 812 to slide up and down along the slide rail to drive the first brush strip 811 to lift. The second brushing member 820 includes two second brush strips 821, and the two second brush strips 821 are installed at intervals, and each second brush strip 821 is vertically arranged. In this embodiment, the second brush strip 821 is installed on the first moving mechanism 400 through a horizontal drive assembly 822. The horizontal drive assembly 822 can be a motor or a cylinder, and in cooperation with a horizontally arranged slide rail, the motor or the cylinder drives the second brush strip 821 to move along the slide rail. According to the positions of the two side walls of the mold cavity 221 of the lower mold 220, the relative positions of the two second brush strips 821 are adjusted to apply a release agent to the side walls of the mold cavity 221. Among them, before the first brushing member 810 and the second brushing member 820 enter the module 200, an external feeding device can be used to soak the first brushing member 810 and the second brushing member 820 with a release agent.

[0077] In some embodiments of the present invention, the fully automatic blanking device further includes a blanking mechanism 900, which is arranged below the blanking mechanism 500. Among them, the blanking mechanism 900 includes a third moving mechanism 910 and a flipping assembly 920. When the clamping assembly 600 clamps and moves the sagger 011 away and moves above the blanking mechanism 900, the clamping assembly 600 moves down and is placed on the third moving mechanism 910, and the clamping hand 610 is released. The sagger 011 is conveyed on the third moving mechanism 910. From the time the sagger 011 is taken out and placed on the third moving mechanism 910, the sagger 011 is in an inverted state, that is, the opening of the sagger 011 faces downward. The flipping assembly 920 is arranged on the conveying path of the third moving mechanism 910. When the sagger 011 is conveyed to the flipping assembly 920, the flipping assembly 920 flips the sagger 011 up and down, that is, the opening side of the sagger 011 faces upward, and then the flipped sagger 011 is placed back on the third moving mechanism 910 and conveyed backward to complete blanking.

[0078] In this embodiment, the specific structure of the blanking mechanism 900 may be, for example Figure 11 and Figure 12As shown, the third moving mechanism 910 includes two third belt conveyor mechanisms 911 that are parallel to each other and spaced apart. The two sides of the sagger 011 are respectively placed on the third belt conveyor mechanisms 911 on both sides, and the two third belt conveyor mechanisms 911 move synchronously. The flipping assembly 920 includes a flipping frame 921 and a flipping drive assembly. Among them, the flipping frame 921 can be, but is not limited to, mainly composed of four straight pipes that are rectangularly distributed in the vertical space and are overlapped. A material supporting opening 922 is formed between the four straight pipes. The flipping frame 921 is installed on the third moving mechanism 910 through a second rotating shaft 930 and bearings 940. The second rotating shaft 930 can pass through the flipping frame 921 and is located at the middle position of the flipping frame 921, so that the flipping frame 921 is divided into two material supporting openings 922 with opposite directions. The second rotating shaft 930 is horizontally installed, and the axial direction of the second rotating shaft 930 is perpendicular to the conveying direction of the third moving mechanism 910. By driving the second rotating shaft 930 to rotate through a motor, the flipping frame 921 can be driven to perform a flipping motion between the two third belt conveyor mechanisms 911. The flipping frame 921 rotates with the second rotating shaft 930, that is, the rotating direction of the flipping frame 921 is to rotate in the vertical space plane. Initially, one of the material supporting openings 922 of the flipping frame 921 faces the conveying direction of the third moving mechanism 910, and the sagger 011 moves with the third moving mechanism 910 and enters the material supporting opening 922. The two sides of the sagger 011 extend to both sides of the flipping frame 921. Then the flipping frame 921 rotates, and rotates clockwise by ° in the illustrated direction, so as to turn the sagger 011 upside down. At this time, the two sides of the sagger 011 are re-placed on the third belt conveyor mechanisms 911 on both sides with the flipping motion of the flipping frame 921, and the sagger 011 moves with the third belt conveyor mechanism 911 and leaves the material supporting opening 922. By setting two opposite material supporting openings 922, the flipping frame 921 can always rotate in the clockwise direction. One material supporting opening 922 is in the action state of the sagger 011 entering, and the other material supporting opening 922 is in the action state of the sagger 011 leaving, thereby improving the flipping efficiency. During the flipping process, the third moving mechanism 910 does not need to stop, and the movement of the third moving mechanism 910 is used to cooperate with the operations of the flipping frame 921 for loading and unloading the sagger 011, and the structure is ingenious.

[0079] A method for manufacturing a sagger by using the above-mentioned fully automatic billet-making equipment at least includes the following steps:

[0080] S1: Quantitatively transfer the amount of powder required to press a sagger 011 blank into the cloth-feeding assembly 340 through the weighing and feeding mechanism 100;

[0081] S2: The feeding mechanism 300 moves into the external module 200. During the process that the fabric component 340 moves above the cavity 221 of the lower mold 220, the fabric component 340 distributes the fabric to the inside and the surrounding of the cavity 221. Before the pressing frame 320 moves to directly above the cavity 221, the fabric component 340 finishes the fabric distribution for the cavity 221.

[0082] S3: The pressing frame 320 descends, and the lower part of the pressing frame 320 is inserted into the peripheral edge 222 of the cavity 221. The upper die punch 210 descends to press down on the pressing frame 320, so as to preform the peripheral plate 013 of the crucible 011 within the peripheral edge 222 of the cavity 221.

[0083] S4: After pre-pressing, the pressing frame 320 ascends to its initial position.

[0084] S5: The feeding mechanism 300 withdraws from the module 200.

[0085] S6: The upper die punch 210 reciprocates up and down multiple times to press the powder in the cavity 221. During the reciprocating pressing process, the four push plates 710 of the feeding mechanism 700 push the powder around the cavity 221 into the cavity 221 for feeding.

[0086] S7: After the crucible 011 is formed, the jacking component 240 jacks up the crucible 011 for demolding; S8: After the crucible 011 is demolded, the blank taking mechanism 500 enters the module 200, and the clamping component 600 takes out the crucible 011.

[0087] S9: When the blank taking mechanism 500 enters and exits the module 200, the oiling mechanism 800 applies a release agent to the upper die punch 210 and the cavity 221.
