Description

Technical Field

[0001] This utility model relates to the field of sealing ring processing technology, and in particular to a ceramic sealing ring processing and forming equipment. Background Technology

[0002] The production and molding process of ceramic sealing rings usually requires two steps: pressing and sintering. The pressing step requires the use of a powder press and a molding die.

[0003] A bidirectional counter-pressure ceramic powder forming hydraulic press with publication number CN219235613U includes a bottom beam, a first hydraulic rod connected to the middle of the bottom beam, a lower movable beam connected to the power end of the first hydraulic rod, guide rods connected to the four corners of the bottom beam, and a top beam connected to the other end of the guide rods. A second hydraulic rod is connected to the middle of the bottom end of the top beam, and an upper movable beam is connected to the power end of the second hydraulic rod. The upper and lower movable beams are slidably connected to the guide rods. A male mold is connected to the bottom end of the upper movable beam, and an extension plate and a female mold that mates with the male mold are connected to the lower movable beam. The upper surface of the female mold is flush with the upper surface of the lower movable beam. A powder storage box and a third hydraulic rod are connected to the extension plate. A feeding box is slidably connected through the bottom end of the powder storage box, and the bottom end of the feeding box mates with the female mold.

[0004] The aforementioned bidirectional pressure ceramic powder forming hydraulic press facilitates rapid feeding and simultaneous transfer feeding, thus improving efficiency. However, during feeding, ceramic powder that is not pressed into a whole with the blank will adhere to the blank surface and enter the guide table together, resulting in waste of ceramic powder and pollution of the production environment. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as ceramic powder that is not pressed into a whole with the blank during feeding, which will adhere to the surface of the blank and enter the guide table together, causing waste of ceramic powder and pollution of the production environment. Therefore, a ceramic sealing ring processing and forming equipment is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a ceramic sealing ring processing and forming equipment, including a worktable, a female mold fixedly installed on the top of the worktable, a male mold installed above the female mold via a lifting component, and a feeding component and an ejection component installed on the top and bottom of the worktable, respectively.

[0008] A guide plate is fixedly connected to the end of the workbench away from the feeding component. A pipe is fixedly installed at the bottom of the guide plate, and a filter component is inside the pipe. Several air inlet slots are opened on the upper surface of the guide plate above the pipe, and a fan is fixedly installed at the lower end of the pipe.

[0009] Furthermore, the lifting assembly includes several columns, with a top plate fixedly connected to the upper end of each column, a drive component one fixedly installed at the bottom of the top plate, a lifting plate fixedly connected to the output shaft of the drive component one via fasteners, a mold fixedly installed at the bottom of the lifting plate, and the lifting plate slidably connected to the outer wall of each column.

[0010] Furthermore, the feeding assembly includes a second driving component fixedly installed at the bottom of the workbench. The output shaft of the second driving component is fixedly connected to a connecting plate. A feeding box is fixedly connected to one end of the connecting plate near the female mold. The bottom of the feeding box is slidably connected to the female mold and the workbench. The top and bottom of the feeding box are open, and a hopper is fixedly provided at the top opening. A pair of limiting plates are fixedly provided at the top of the workbench, and the feeding box is slidably disposed between the pair of limiting plates.

[0011] Furthermore, the ejection assembly includes a drive component three fixedly installed at the bottom of the worktable. The output shaft of the drive component three is fixedly connected to a horizontal plate. Several sets of ejector pins are fixedly connected to the top of the horizontal plate. Each set of ejector pins passes through the worktable and the female mold and extends into the annular forming groove of the female mold. Each set of ejector pins is arranged in a circumferential array in an annular forming groove.

[0012] Furthermore, the filter assembly includes a slot formed on the front end face of the pipe, a collection box is inserted into the slot, the bottom of the collection box has an opening, and a filter screen is fixedly installed in the opening.

[0013] Furthermore, the bottom of the workbench is fixedly connected to several legs, and a support plate is fixedly installed on the outer wall of the legs. The lower end of the guide plate is fixedly connected to the support plate, and a through hole is opened through the top of the support plate, with a pipe welded inside the through hole.

[0014] Furthermore, a pair of baffles located on both sides of several air inlet slots are fixedly connected to the upper end face of the guide plate, and two inclined plates are fixedly connected to the upper end face of the guide plate. The upper ends of the two inclined plates are respectively inclined to both sides and fixedly connected to two baffles.

[0015] The ceramic sealing ring processing and forming equipment proposed in this utility model has the following advantages: the air above the guide plate is drawn into the pipeline through several air inlet slots by a blower, and then discharged through the pipeline. Before entering the air inlet slots, the air passes through and carries away the ceramic particles adhering to the blank. When passing through the pipeline, it passes through the filter assembly and is filtered out and the ceramic powder is collected. This effectively prevents the ceramic sealing ring blank from adhering to the excess ceramic powder during feeding, thus avoiding pollution of the overloaded environment and waste of ceramic powder.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 As an embodiment of this utility model, a ceramic sealing ring processing and forming equipment is disclosed, including a worktable 1, a female mold 2 is fixedly installed on the top of the worktable 1, a male mold 4 is installed above the female mold 2 through a lifting component 3, and a feeding component 5 and an ejection component 6 are respectively installed on the top and bottom of the worktable 1.

[0023] Ceramic powder is fed into the female mold 2 through the feeding component 5. The male mold 4 is lowered and inserted into the female mold 2 through the lifting component 3. The ceramic powder in the female mold 2 is pressed into a ring-shaped ceramic sealing ring blank. The blank is then ejected from the female mold 2 through the ejection component 6. The blank is pushed to the right by the feeding component 5 to detach it from the worktable 1. Then, the ceramic powder is fed into the female mold 2 through the feeding component 5 for the second molding.

[0024] A guide plate 7 is fixedly connected to the end of the workbench 1 away from the feeding component 5. A pipe 8 is fixedly installed at the bottom of the guide plate 7, and a filter component 9 is inside the pipe 8. Several air inlet slots 10 are opened on the upper surface of the guide plate 7 above the pipe 8. A fan 11 is fixedly installed at the lower end of the pipe 8.

[0025] Under the action of the feeding component 5, the blank moves to the right onto the guide plate 7 and slides along the guide plate 7 to complete the feeding. The air above the guide plate 7 is drawn into the pipe 8 through several air inlet slots 10 by the fan 11, and then discharged through the pipe 8. Before entering the several air inlet slots 10, the air passes through and carries away the ceramic particles adhering to the blank. When passing through the pipe 8 and the filter component 9, the ceramic powder contained therein is filtered out and collected. This effectively prevents the ceramic sealing ring blank from adhering to the excess ceramic powder during feeding, thus avoiding pollution of the overloaded environment and waste of ceramic powder.

[0026] In some embodiments, the lifting assembly 3 includes a plurality of columns 31, the upper ends of the plurality of columns 31 are fixedly connected to a top plate 32, a drive component 33 is fixedly installed at the bottom of the top plate 32, the output shaft of the drive component 33 is fixedly connected to a lifting plate 34 by fasteners, a male mold 4 is fixedly installed at the bottom of the lifting plate 34, and the lifting plate 34 is slidably connected to the outer wall of the plurality of columns 31. Preferably, the drive component 33 is a hydraulic cylinder, which drives the lifting plate 34 and the male mold 4 to rise and fall.

[0027] Specifically, the feeding assembly 5 includes a second driving component 51 fixedly installed at the bottom of the workbench 1. The output shaft of the second driving component 51 is fixedly connected to a connecting plate 52. A feeding box 53 is fixedly connected to one end of the connecting plate 52 near the female mold 2. The bottom of the feeding box 53 is slidably connected to the female mold 2 and the workbench 1. The top and bottom of the feeding box 53 are open, and a hopper 54 is fixedly provided at the top opening. A pair of limiting plates 55 are fixedly provided at the top of the workbench 1. The feeding box 53 is slidably disposed between the pair of limiting plates 55. Preferably, the second driving component 51 is an electric push rod.

[0028] The electric push rod drives the connecting plate 52 to move left and right, thereby causing the feeding box 53 to slide left and right between a pair of limit plates 55. This allows the ceramic powder to fall into the mother mold 2 when the bottom opening of the feeding box 53 passes through the mother mold 2, thus completing the feeding process. The ceramic powder is then injected into the feeding box 53 through the hopper 54.

[0029] For example, the ejection assembly 6 includes a drive component 61 fixedly installed at the bottom of the worktable 1. The output shaft of the drive component 61 is fixedly connected to a horizontal plate 62. A plurality of sets of ejector pins 63 are fixedly connected to the top of the horizontal plate 62. Each set of ejector pins 63 passes through the worktable 1 and the female mold 2 and extends into the annular forming groove 21 of the female mold 2. Each set of ejector pins 63 is arranged in a circumferential array in an annular forming groove 21. Preferably, the drive component 61 is a cylinder.

[0030] The extension and retraction of the cylinder output shaft drives the horizontal plate 62 to rise and fall, thereby driving the horizontal plate 62 and several sets of ejector pins 63 on it to rise, lifting the blank in the annular forming groove 21 until the upper end of the ejector pin 63 is flush with the top of the female mold 2.

[0031] It should be noted that the filter assembly 9 includes a slot 91 opened on the front end face of the pipe 8, a collection box 92 is inserted into the slot 91, the bottom of the collection box 92 has an opening, and a filter screen 93 is fixedly installed in the opening. Preferably, a handle is fixedly installed at the front end of the collection box 92, and rubber molds to increase friction and airtightness are glued to the outer walls of both ends of the front end of the collection box 92.

[0032] Air containing ceramic powder enters the collection box 92 through the pipe 8 and passes through the filter screen 93. After passing through the filter screen 93, the air enters the fan 11 and is discharged. The ceramic powder in the air is filtered out by the filter screen 93. The filtered ceramic powder can be recycled and reused by pulling out the collection box 92 by the handle.

[0033] In detail, the bottom of the workbench 1 is fixedly connected with several legs 12, and a support plate 13 is fixedly installed on the outer wall of the legs 12. The lower end of the guide plate 7 is fixedly connected to the support plate 13. The top of the support plate 13 has a through hole 14, and the inside of the through hole 14 is welded with a pipe 8. Preferably, the top of the support plate 13 has a groove located on the right side of the guide plate 7. The groove is used to accommodate the ceramic sealing ring blank. The support plate 13 supports the guide plate 7 and the pipe 8.

[0034] Furthermore, the upper end face of the guide plate 7 is fixedly connected to a pair of baffles 15 located on both sides of several air inlet slots 10. The upper end face of the guide plate 7 is fixedly connected to two inclined plates 16, one above the other. The upper ends of the two inclined plates 16 are respectively inclined to both sides and fixedly connected to two baffles 15. The pair of baffles 15 prevents the ceramic sealing ring blank from falling from the front and rear sides of the guide plate 7. With the cooperation of the two inclined plates 16, when the ceramic sealing ring blank slides down the guide plate 7, it first collides with the upper inclined plate 16, then moves forward along the upper inclined plate 16 and hits the front baffle 15, and then moves backward along the lower inclined plate 16. This increases the movement time of the ceramic sealing ring blank on the guide plate 7, making dust removal more thorough. At the same time, the impact accelerates the falling of ceramic powder on the ceramic sealing ring blank.

[0035] Working method: During operation, ceramic powder is injected into the feeding box 53 through the hopper 54. First, the connecting plate 52 is moved to the right above the mother mold 2 by the second drive component 51, so that the ceramic powder in the feeding box 53 falls into and fills the annular forming groove 21 of the mother mold 2 through the bottom opening of the feeding box 53. Then, the feeding box 53 is moved to the left and reset by the second drive component 51, and the ceramic powder on the mother mold 2 is smoothed by the feeding box 53.

[0036] Driven by the drive component 33, the lifting plate 34 and the male mold 4 are lowered, so that the male mold 4 and the female mold 2 are closed and the ceramic powder in the annular forming groove 21 is pressed to form a blank. Then, the drive component 33 drives the male mold 4 to rise and reset.

[0037] The drive component 61 drives the horizontal plate 62 to rise, thereby driving the horizontal plate 62 and several sets of ejector pins 63 on it to rise, lifting the blank in the annular forming groove 21 until the upper end of the ejector pins 63 is flush with the top of the female mold 2.

[0038] Driven by the second drive component 51, the feeding box 53 moves to the right, pushing the ceramic sealing ring blank at the top of the ejector pin 63 to the right so that it enters the guide plate 7 and then falls onto the tray 13 along the guide plate 7. The blower 11 draws air from the top of the guide plate 7 into the pipe 8, forming an airflow into the air inlet groove 10. As a result, the ceramic powder on the ceramic sealing ring blank is carried away by the airflow after passing through it.

[0039] First, drive the horizontal plate 62 to descend via drive component 3 61, so that the ejector pin 63 descends until the upper end of the ejector pin 63 is flush with the bottom of the annular forming groove 21. Then, drive the feeding box 53 to move to the left above the annular forming groove 21 via drive component 2 51, and fill the annular forming groove 21 with ceramic powder again. The feeding box 53 continues to move to the left to smooth the ceramic powder.

[0040] The lifting plate 34 and the male mold 4 are lowered again by the driving component 33 to form the second ceramic sealing ring blank.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
