Description

Technical Field

[0001] The invention relates to the technical field of graphite crucible manufacturing, and in particular to a processing device for processing a graphite crucible. Background Art

[0002] Graphite crucibles are made from materials such as clay, graphite, and silica, which are processed into graphite powder of a certain size through processes such as crushing, screening, impurity removal, and water washing, and are then pressed into shape using a graphite crucible mold. In the traditional graphite crucible pressing process, pressure is applied to the upper and lower molds through a press or other equipment, so that the graphite powder is formed into a crucible under pressure.

[0003] In traditional graphite crucible pressing and forming operations, there are gaps between graphite powders when the molds are connected, resulting in gaps inside the crucible after pressing, affecting the quality of the graphite crucible. In order to solve this problem, in some graphite crucible pressing and forming operations, it is necessary to knock on the outside of the crucible with a tool during the pressing process to make the graphite powder inside the mold more densely distributed under the action of vibration, thereby reducing the generation of gaps inside the graphite powder. However, it is not easy to control the knocking force and achieve the best effect by vibrating the crucible pressing mold with external force. In some graphite crucible pressing and forming equipment with a vibration function, the installation of the vibration equipment will increase the volume of the mold and is easily blocked by graphite powder and cause failures. External drive parts and power supply lines are also required, which increases the manufacturing cost of the equipment and the complexity of maintenance. Summary of the invention

[0004] The present invention discloses a processing device for processing a graphite crucible, so as to solve the problem that it is difficult to control the striking force and achieve the best effect by vibrating a crucible pressing mold with an external force. In some graphite crucible pressing and forming equipment with a vibrating function, the installation of the vibrating equipment will increase the volume of the mold, and it is easy to be blocked by graphite powder and cause failure. In addition, an external driving part and power supply lines are required, which increases the manufacturing cost of the equipment and makes the maintenance complicated.

[0005] In a first aspect of the present disclosure, a processing device for processing a graphite crucible is provided, specifically comprising: a press, a rotary drive member is installed above the interior of the press, a crucible outer mold is fixedly connected above the lifting platform inside the press, a motor receiving plate is fixedly connected below the rotary drive member, an inner mold connecting seat is installed below the motor receiving plate by bolts, a crucible inner mold is installed below the inner mold connecting seat, a guide cylinder is fixedly connected below the inner mold connecting seat, an inner mold guide plate is fixedly connected inside the crucible inner mold, and the guide cylinder vertically penetrates and slides The inner mold guide plate is connected, and two telescopic connecting rods are fixedly connected to the lower part of the inner mold connecting seat, and the telescopic connecting rods vertically penetrate the inner mold guide plate. The lower end of the telescopic connecting rod is fixedly connected to a hinged end shaft, and a one-way rotating cylinder is installed on the outside of the hinged end shaft through a ratchet and pawl mechanism. Six knocking wedges are installed on the one-way rotating cylinder, and the inner surface of the knocking wedge is fixedly connected to a wedge guide rod, and the wedge guide rod is slidably connected to the one-way rotating cylinder. The outer shell of the wedge guide rod is connected to a knocking force storage top spring, and the inner mold of the crucible is fixedly connected to the inner mold wedge teeth, and the knocking wedges close to the inside of the inner mold of the crucible are in fit with the inner mold wedge teeth.

[0006] Furthermore, the guide tube outer shell is connected with a reset spring, the upper end of the reset spring is fixedly connected to the lower surface of the inner mold connecting seat, the lower end of the reset spring is fixedly connected to the inner mold guide plate, and the lower end of the guide tube is fixedly sleeved with a limiting convex ring.

[0007] Furthermore, the front and rear ends of the hinged end shaft are respectively fixedly connected with a ratchet ring, and six ratchets are arranged outside the ratchet ring. The tip of the ratchet inside the left ratchet ring faces counterclockwise, and the tip of the ratchet inside the right ratchet ring faces clockwise.

[0008] Furthermore, the front end and the rear end of the one-way rotary drum are respectively fixedly connected with a rotary drum ratchet, and the inner surface of the rotary drum ratchet is fixedly connected with six ratchet teeth.

[0009] Furthermore, the outward side of the striking wedge is an inclined surface, the inner end of the wedge guide rod is fixedly connected to the limited end block, and the wedge guide rod is perpendicular to the axis of the one-way rotary cylinder.

[0010] Furthermore, the outer end of the striking force storage spring is fixedly connected to the side of the striking wedge facing the one-way rotating cylinder, and the inner end of the striking force storage spring is fixedly connected to the outer surface of the one-way rotating cylinder.

[0011] Furthermore, inner mold wedge teeth are longitudinally arranged on the left and right sides of the inner wall of the inner mold of the crucible, respectively, and the wedge surfaces of the inner mold wedge teeth face inward and upward.

[0012] Furthermore, the bottom center of the crucible outer mold and the press lifting platform are both penetrated with openings, and a discharge push rod is vertically installed at the bottom of the press, and the upper end of the discharge push rod is fixedly connected to a demoulding top platform, which is connected to the bottom opening of the crucible outer mold.

[0013] The present invention provides a processing device for processing a graphite crucible, which has the following beneficial effects: The present invention improves the pressing mold of graphite powder for pressing and molding a graphite crucible, and improves the structure inside and above the inner mold of the crucible. The inner mold connecting seat is movably connected to the inner mold of the crucible, and there is a gap of a certain distance under normal conditions. During the pressing process of the graphite powder, as the inner mold of the crucible and the outer mold of the crucible gradually approach each other, pressure is applied to the inner mold of the crucible, so that the inner mold of the crucible gradually approaches the inner mold connecting seat and finally fits together. In this process, the knocking wedge block located inside the inner mold of the crucible slides downward along the inner mold wedge teeth arranged longitudinally, and the knocking wedge block is repeatedly knocked down by the inclined surface of the inner mold wedge teeth. Pushing laterally compresses the striking force-storing top spring to store force, and pushing the striking wedge outward at the moment the striking wedge separates from the wedge teeth of the inner mold, repeatedly striking the inner wall of the crucible inner mold to vibrate the graphite powder inside the mold. Vibration increases the distribution density of the graphite powder, and in this process, vibration of the mold is achieved without the need for an external drive component. Compared with traditional graphite crucible pressing and molding equipment with a vibrating function, the equipment size is reduced, no additional drive components are required, costs are reduced, and maintenance is more convenient. The use of an internal vibration setting can avoid graphite powder clogging the transmission structure and bearings and causing failures.

[0014] In addition, the striking wedge is installed through the one-way rotary drum. During the pressing and forming, when the one-way rotary drum and the striking wedge are close to the bottom of the crucible inner mold, the one-way rotary drum cannot rotate due to the ratchet pawl transmission between the pawl ring and the rotary drum ratchet, so that the striking wedge and the inner mold wedge teeth form friction and expand and contract horizontally under the push of the inclined surface. After the pressing is completed, as the crucible outer mold moves downward, the crucible inner mold is separated from the crucible outer mold, and the crucible inner mold is separated from the inner mold connecting seat under the thrust of the reset push spring. When the one-way rotary drum and the striking wedge are away from the bottom of the crucible inner mold, the striking wedge contacts the inner mold wedge teeth, so that the one-way rotary drum moves up and drives the striking wedge to rotate at the same time, so that the inner mold connecting seat, the one-way rotary drum and the crucible inner mold return to their normal positions, so that the pressing of graphite powder can be carried out continuously.

[0019] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1 to 9 : The present invention proposes a processing device for processing a graphite crucible, comprising: a press machine 1, a rotary drive member 2 is installed above the inside of the press machine 1, a crucible outer mold 9 is fixedly connected to the top of the lifting platform inside the press machine 1, a motor receiving plate 3 is fixedly connected below the rotary drive member 2, an inner mold connecting seat 4 is installed below the motor receiving plate 3 by bolts, and the inner mold connecting seat 4 is conveniently disassembled by bolt connection between the motor receiving plate 3 and the inner mold connecting seat 4 for repair and maintenance of the equipment, a crucible inner mold 8 is installed below the inner mold connecting seat 4, and the inner mold connecting seat 4 is fixedly connected with a guide cylinder 401 below, an inner mold guide plate 802 is fixedly connected inside the crucible inner mold 8, the guide cylinder 401 vertically penetrates and slidably connects to the inner mold guide plate 802, two telescopic connecting rods 5 are fixedly connected below the inner mold connecting seat 4, the telescopic connecting rods 5 vertically penetrate the inner mold guide plate 802, the lower end of the telescopic connecting rod 5 is fixedly connected with a hinged end shaft 501, a one-way rotating cylinder 6 is installed outside the hinged end shaft 501 through a ratchet pawl mechanism, six knocking wedges 7 are installed on the one-way rotating cylinder 6, the inner surface of the knocking wedge 7 is fixedly connected with a wedge guide rod 701, and the wedge The guide rod 701 is slidably connected to the one-way rotating cylinder 6, the outer sleeve of the wedge guide rod 701 is connected with a knocking force storage top spring 702, the inner mold wedge teeth 801 are fixedly connected to the inside of the crucible inner mold 8, and the knocking wedge block 7 close to the inside of the crucible inner mold 8 fits with the inner mold wedge teeth 801; a movable crucible inner mold 8 is provided, and the crucible inner mold 8 is movably connected to the inner mold connecting seat 4. During the pressing process of graphite powder, as the crucible inner mold 8 and the crucible outer mold 9 gradually approach each other, pressure is applied to the crucible inner mold 8, so that the crucible inner mold 8 gradually approaches the inner mold connecting seat 4 and finally fits together. During this process, the striking wedge 7 located inside the crucible inner mold 8 slides downward along the longitudinally arranged inner mold wedge teeth 801, and the striking wedge 7 is repeatedly pushed laterally under the action of the inclined surface of the inner mold wedge teeth 801, so that the striking force storage top spring 702 is compressed and stored, and the striking wedge 7 is pushed outward at the moment when the striking wedge 7 is separated from the inner mold wedge teeth 801, and the inner wall of the crucible inner mold 8 is repeatedly struck, thereby vibrating the graphite powder inside the mold, and increasing the distribution density of the graphite powder inside the crucible outer mold 9 before pressing by vibration, so that the crucible can be pressed more tightly.

[0021] By setting the rotating driving member 2, the inner mold connecting seat 4 and the crucible inner mold 8 are driven to rotate by the rotating driving member 2 during the pressing process, so that the outer surface of the crucible inner mold 8 rubs against the graphite powder inside the crucible outer mold 9, which helps to distribute the graphite powder more evenly in the mold. This can ensure that the density and thickness of each part of the crucible remain consistent during the molding process, thereby improving the quality and consistency of the finished product. It also helps to remove the gas in the mold during the pressing process, which can reduce the pores and defects in the crucible, and further improve its quality and durability. In the embodiment of the present disclosure, the transmission structure and the linkage structure for striking and vibrating the crucible inner mold 8 are combined in the inner mold connecting seat 4 and the crucible inner mold 8, and the striking and vibrating function of the mold will not be affected by the rotation of the inner mold connecting seat 4 and the crucible inner mold 8.

[0023] In the embodiment of the present disclosure, the outward side of the knocking wedge 7 is an inclined surface, the inner end of the wedge guide rod 701 is fixedly connected to the limited end block, and the wedge guide rod 701 is perpendicular to the axis of the one-way rotating cylinder 6; the outer end of the knocking force storage top spring 702 is fixedly connected to the side of the knocking wedge 7 facing the one-way rotating cylinder 6, and the inner end of the knocking force storage top spring 702 is fixedly connected to the outer surface of the one-way rotating cylinder 6, and the inner mold wedge teeth 801 are longitudinally arranged on the left and right sides of the inner wall of the crucible inner mold 8, and the wedge surface of the inner mold wedge teeth 801 faces inward and upward; under normal conditions, the knocking wedge 7 is pushed outward by the knocking force storage top spring 702. The crucible inner mold 8 and the crucible outer mold 9 gradually approach each other, and pressure is applied to the crucible inner mold 8, so that the crucible inner mold 8 gradually approaches the inner mold connecting seat 4 and finally fits together as one. During this process, the striking wedge 7 located inside the crucible inner mold 8 slides downward along the longitudinally arranged inner mold wedge teeth 801, and the striking wedge 7 is repeatedly pushed laterally under the action of the inclined surface of the inner mold wedge teeth 801, so that the striking force storage top spring 702 is compressed and stored, and the striking wedge 7 is pushed outward at the moment the striking wedge 7 is separated from the inner mold wedge teeth 801, and the inner wall of the crucible inner mold 8 is repeatedly struck to realize the vibration function of the mold.

[0024] In the disclosed embodiment, openings are provided at the bottom center of the crucible outer mold 9 and the lifting platform of the press 1, and a discharge push rod is vertically installed at the bottom of the press 1, and a demolding top platform is fixedly connected to the upper end of the discharge push rod, and the demolding top platform is connected to the bottom opening of the crucible outer mold 9; after the pressing of the crucible is completed, the push cylinder of the press 1 controls the lifting platform and the crucible outer mold 9 to move downward, and the crucible is separated from the inside of the crucible outer mold 9 by the stationary demolding top platform to complete the demolding work.

[0025] Embodiment 2, on the basis of embodiment 1, the front end and the rear end of the hinged end shaft 501 are respectively fixedly connected with a ratchet ring 502, and the ratchet ring 502 is provided with six ratchets, the tip of the ratchet inside the left ratchet ring 502 faces counterclockwise, and the tip of the ratchet inside the right ratchet ring 502 faces clockwise; the front end and the rear end of the one-way rotary drum 6 are respectively fixedly connected with a rotary drum ratchet 601, and the inner surface of the rotary drum ratchet 601 is fixedly connected with six ratchet teeth 602, and the ratchet ring 502 cooperates with the rotary drum ratchet 601 to form a ratchet and ratchet transmission mechanism, so that the one-way rotary drum 6 and the knocking wedge 7 are locked and cannot rotate when approaching the bottom of the crucible inner mold 8, and can rotate and interact when the one-way rotary drum 6 and the knocking wedge 7 are away from the bottom of the crucible inner mold 8, so as to avoid the knocking wedge 7 from contacting with the inner mold wedge teeth 801 and getting stuck during the resetting of the equipment.

[0026] The working principle of this embodiment is as follows: first, add a proper amount of graphite powder to the inside of the crucible outer mold 9, start the rotary drive member 2, drive the inner mold connecting seat 4 and the crucible inner mold 8 to rotate through the rotary drive member 2, and then control the action of the press 1, and pull the lifting platform and the crucible outer mold 9 upward through the hydraulic cylinder in the press 1. As the crucible outer mold 9 moves upward, the bottom of the crucible inner mold 8 enters the inside of the crucible outer mold 9 and contacts with the graphite powder to extrude the graphite powder. Under the action of the rotation of the crucible inner mold 8, the outer surface of the crucible inner mold 8 rubs against the graphite powder inside the crucible outer mold 9, which helps to distribute the graphite powder more evenly in the mold. This can ensure that the density and thickness of each part of the crucible are consistent during the molding process, thereby improving the quality and consistency of the finished product, and also helps to remove the gas in the mold during the pressing process, which can reduce the pores and defects in the crucible. During this process, the inner mold connecting seat 4 and the crucible inner mold 8 gradually approach and merge, and the reset push spring 402 is gradually compressed. At the same time, the knocking wedge block 7 located inside the crucible inner mold 8 gradually approaches the bottom surface of the crucible inner mold 8, and forms a sliding connection with the inner mold wedge teeth 801 arranged along the longitudinal direction. Due to the ratchet pawl transmission between the ratchet pawl ring 502 and the rotary drum ratchet 601 The one-way rotary cylinder 6 cannot rotate, so that the knocking wedge block 7 and the inner mold wedge tooth 801 form friction and expand and contract horizontally, and the knocking wedge block 7 is pushed laterally under the action of the inclined surface of the inner mold wedge tooth 801, so that the knocking force storage top spring 702 is compressed and stored, and the knocking wedge block 7 is pushed outward at the moment when the knocking wedge block 7 is separated from the inner mold wedge tooth 801, and the inner wall of the crucible inner mold 8 is repeatedly knocked to realize the vibration of the graphite powder inside the mold. The distribution density of the graphite powder in the fully pressed state is higher through vibration, and the pressing density of the graphite crucible is improved; after the pressing is completed, the hydraulic cylinder in the press machine 1 is controlled to push the lifting platform down, and the crucible is pressed. The crucible outer mold 9 moves downward, the crucible inner mold 8 is separated from the crucible outer mold 9, and the crucible inner mold 8 is separated from the inner mold connecting seat 4 under the thrust of the reset push spring 402. In the process of the one-way rotary cylinder 6 and the knocking wedge block 7 moving away from the bottom of the crucible inner mold 8, the knocking wedge block 7 contacts the inner mold wedge teeth 801, so that the one-way rotary cylinder 6 moves up and drives the knocking wedge block 7 to rotate, so that the inner mold connecting seat 4, the one-way rotary cylinder 6, and the crucible inner mold 8 return to their normal positions. As the lifting platform and the crucible outer mold 9 continue to move downward, the crucible is ejected from the inside of the crucible outer mold 9 by the stationary demolding top platform, thereby completing the demolding work of the graphite crucible.
