Description

Technical Field

[0001] This utility model relates to the field of molding equipment, specifically to a ceramic sealing ring molding device. Background Technology

[0002] Ceramic sealing rings are industrial sealing components made of high-performance ceramic materials such as alumina and silicon carbide combined with special rubber. They have characteristics such as high temperature resistance, high wear resistance, and corrosion resistance, and are widely used in vertical mill equipment, new energy batteries, chemical machinery and other fields.

[0003] The production process of ceramic sealing rings includes: raw material preparation, molding, sintering, surface treatment and testing. The commonly used equipment in the molding process is a press. Existing presses are prone to causing ceramic sealing rings to stick together after pressing. Therefore, it is necessary to design a ceramic sealing ring molding device that does not easily cause ceramic sealing rings to stick together. Summary of the Invention

[0010] Preferably, the rotating mechanism includes a hydraulic motor and a driven gear ring. The hydraulic motor is mounted on the lifting frame and has a drive gear. The driven gear ring is coaxially and fixedly connected to the support ring, and the drive gear meshes with the driven gear ring.

[0011] Preferably, the upper end of the limiting post is chamfered.

[0012] Compared to existing technologies, the advantages are:

[0013] This invention utilizes a rotating mechanism and a lifting unit to drive the support ring to rotate and rise within the limiting tube, thereby separating the pressed ceramic sealing ring from the support ring, the limiting tube, and the limiting post, reducing the adhesion between the pressed ceramic sealing ring and the support ring, the limiting tube, and the limiting post.

[0019] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 4 As shown:

[0020] Example 1: A ceramic sealing ring forming device includes a support platform 1. The upper end of the support platform 1 is provided with a through hole, and the lower end of the through hole is connected to a limiting tube 2. A limiting post 3 is vertically arranged inside the limiting tube 2. The upper end of the limiting tube 2 is flush with the upper end surface of the support platform 1. The lower end of the limiting post 3 is provided with a portal frame 4 connected to the support platform 1. The portal frame 4 serves to support the limiting post 3.

[0021] A lifting frame 5 is sleeved on the outside of the limiting post 3. A support ring 6 is rotatably installed at the upper end of the lifting frame 5. The support ring 6 is slidably connected to the limiting tube 2. A rotating mechanism connected to the support ring 6 is installed inside the lifting frame 5. The rotating mechanism drives the support ring 6 to rotate on the lifting frame 5 and inside the limiting tube 2. The support ring 6 is rotatably and sealingly connected to the inner wall of the support ring 6. A lifting unit connected to the lifting frame 5 is installed inside the support platform 1. The lifting unit drives the lifting frame 5 and the support ring 6 to rise and fall synchronously.

[0022] A frame 12 is provided at the upper end of the support platform 1. A first telescopic cylinder 11 is vertically provided at the upper end of the frame 12. A pressure ring 13 corresponding to the upper and lower limits of the limit tube 2 is connected to the lower end of the first telescopic cylinder 11. The first telescopic cylinder 11 drives the pressure ring 13 to rise and fall. Before the ceramic sealing ring is pressed, the powder raw material is put into the support ring 6 between the limit column 3 and the limit tube 2. The first telescopic cylinder 11 is controlled to descend. The pressure ring 13 is used to penetrate into the limit tube 2 to apply pressure to the powder raw material and press the powder raw material into a whole to form a ceramic sealing ring. Then the first telescopic cylinder 11 is controlled to drive the pressure plate to retract.

[0023] Subsequently, the rotating mechanism drives the support ring 6 to rotate, while the lifting unit drives the support ring 6 to rise and fall, pushing out the formed ceramic sealing ring. The support ring 6 rotates and rises within the limiting tube 2, preventing the formed ceramic sealing ring from sticking to the support ring 6, the limiting tube 2, and the limiting post 3.

[0024] Example 2: A ceramic sealing ring forming device includes a support platform 1. The upper end of the support platform 1 is provided with a through hole, and the lower end of the through hole is connected to a limiting tube 2. A limiting post 3 is vertically arranged inside the limiting tube 2. The upper end of the limiting post 3 is chamfered. The upper end of the limiting tube 2 is flush with the upper surface of the support platform 1. The lower end of the limiting post 3 is provided with a portal frame 4 connected to the support platform 1. The portal frame 4 serves to support the limiting post 3.

[0025] A lifting frame 5 is sleeved on the outer side of the limiting post 3. A support ring 6 is rotatably installed at the upper end of the lifting frame 5. A bearing is installed between the lifting frame 5 and the support ring 6. The bearing is a thrust roller bearing, which can withstand a large axial force.

[0026] The support ring 6 is slidably connected to the limiting tube 2. The lifting frame 5 is provided with a rotating mechanism connected to the support ring 6. The rotating mechanism includes a hydraulic motor 7 and a driven gear ring 8. The hydraulic motor 7 is mounted on the lifting frame 5 and is equipped with a drive gear. The driven gear ring 8 is coaxially and fixedly connected to the support ring 6, and the drive gear meshes with the driven gear ring 8.

[0027] The rotating mechanism drives the support ring 6 to rotate on the lifting frame 5. The support ring 6 rotates inside the limiting tube 2. The support ring 6 is rotatably sealed to the inner wall of the support ring 6. The support platform 1 is equipped with a lifting unit connected to the lifting frame 5. The lifting unit drives the lifting frame 5 and the support ring 6 to rise and fall synchronously.

[0028] The lifting unit includes a vertically extending second telescopic cylinder 10. A frame 12 is provided at the upper end of the support platform 1. A first telescopic cylinder 11 is vertically provided at the upper end of the frame 12. A pressure ring 13 corresponding to the upper and lower limit tube 2 is connected to the lower end of the first telescopic cylinder 11. The first telescopic cylinder 11 drives the pressure ring 13 to rise and fall. Both the second telescopic cylinder 10 and the first telescopic cylinder 11 are hydraulic cylinders. A hydraulic station 14 and a hydraulic control unit are provided on the outside of the support platform 1. The hydraulic station 14 is provided with hydraulic pipelines connected to the second telescopic cylinder 10, the first telescopic cylinder 11 and the hydraulic motor 7.

[0029] The working principle is as follows:

[0030] Before pressing the ceramic sealing ring, the powder material is fed onto the support ring 6 between the limiting post 3 and the limiting tube 2. The first telescopic cylinder 11 is controlled to descend, and the pressure ring 13 extends into the limiting tube 2 to apply pressure to the powder material, pressing it into a single ceramic sealing ring. Then, the first telescopic cylinder 11 is controlled to retract the pressure plate. Subsequently, the rotating mechanism drives the support ring 6 to rotate, while the lifting unit drives the support ring 6 to rise and fall, pushing out the formed ceramic sealing ring. The support ring 6 rotates and rises within the limiting tube 2, preventing the formed ceramic sealing ring from sticking to the support ring 6, the limiting tube 2, and the limiting post 3.
