Description

Technical Field

[0001] This invention belongs to the field of ceramic sintering production technology, specifically a rolling forming device for ceramic sintering production. Background Technology

[0002] Ceramic sintering is the core process in ceramic product manufacturing, while roll forming is a crucial pre-process before sintering. The compactness, surface regularity, and internal purity of the rolled body directly determine the quality, yield, and service life of the final sintered product. The core function of roll forming is to compact and shape the ceramic clay body, expel air trapped during the forming process, and ensure a uniform and stable body structure, laying a solid foundation for high-temperature sintering. Currently, roll forming equipment has been widely adopted in the ceramic sintering production field to replace traditional manual shaping and simple molding processes, significantly improving the efficiency of body forming.

[0003] Existing traditional ceramic green body roll forming equipment has a single structure and function, mostly only possessing the functions of mechanical extrusion and rotary roll forming. During the roll forming process, it can only achieve surface compaction and shaping of the green body, lacking a targeted defoaming structure design. During the mixing, spreading, and preforming processes of ceramic green bodies, a large number of tiny air bubbles are easily trapped. Traditional roll forming methods rely solely on static pressure to compact the green body, which cannot effectively disperse and expel the tiny air bubbles deep inside the green body. This results in a large number of micropores and voids in the formed green body. When the green body with these voids enters the high-temperature sintering process, the internal air bubbles expand due to heat, which can easily cause sintering defects. The finished products have quality problems such as cracking, bulging, deformation, and local loosening, which greatly reduces the structural strength and appearance quality of the ceramic products. The yield rate is low, which increases production loss and production costs. Most traditional equipment is only equipped with a single specification of roller pressing mold, which can only realize large-area overall roller pressing operations. It cannot perform fine-tuning of the edges and corners of the ceramic body, local unevenness, and minor defects. Some subdivided roller pressing equipment can only realize small-area fine roller pressing, which cannot complete the efficient compaction of the whole body. It cannot flexibly switch the processing mode according to different specifications and shapes of ceramic bodies, and has poor adaptability. Summary of the Invention

[0015] The beneficial effects of this invention are as follows: 1. This invention, by setting up a vibratory de-bubbling roller pressing assembly, uses a lead screw to drive the screw sleeve to rotate, which in turn drives the biased vibrating block to rotate at high speed to generate continuous micro-vibration. Combined with the rotating roller pressing operation of the outer roller pressing mold, it can fully disperse and expel the tiny air bubbles trapped inside the green body during the green body roller pressing process, effectively eliminating the defects of pores and voids inside the green body, avoiding problems such as cracking and bulging in the subsequent sintered finished product, and greatly improving the density of the ceramic green body and the quality of the finished product.

[0017] 3. This invention utilizes a scraper and buffer spring inside the vibratory de-bubbling roller pressing assembly, which rotate synchronously with the outer roller pressing mold. The elastic pressing action of the buffer spring ensures that the scraper always adheres to the roller pressing end face of the blank, automatically scraping away excess material extruded from the ceramic blank during the roller pressing process. This effectively regularizes the shape of the blank, preventing the accumulation of excess material from affecting the forming accuracy. It eliminates the need for manual secondary trimming, simplifies the processing steps, and improves the regularity of the blank forming. At the same time, it can automatically scrape away excess clay on the surface of the blank during the roller pressing process, smoothing the surface flatness. It is suitable for the fine forming needs of ceramic blanks of different specifications, making it more versatile and practical.

[0018] 4. This invention uses a single motor to drive the vibration-type de-bubbling roller assembly and the fixed small roller assembly to rotate, while also enabling the vibration-type de-bubbling roller assembly to vibrate and eliminate internal bubbles. It can also scrape off scrap materials and prevent the accumulation of scrap materials. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 15As shown, this embodiment of the invention provides a rolling forming device for ceramic sintering production, including a housing 1. Multiple heat-conducting plates 2 are provided in the middle of the housing 1. A receiving frame 3 is fixedly connected inside the housing 1. A servo motor 4 is fixedly connected to the upper end of the receiving frame 3. A drive bevel gear 5 is fixedly connected to the output end of the servo motor 4. A reciprocating drive turntable 6 is fixedly connected to one end of the drive bevel gear 5. A pair of symmetrical fixing plates 7 are fixedly connected inside the housing 1 by bolts. A pair of symmetrically positioned limiting plates 8 are fixedly connected between the pair of fixing plates 7. Multiple limiting rods 9 are fixedly connected between the pair of limiting plates 8. A pair of symmetrical sliding plates 10 are slidably connected to the middle of multiple limiting rods 9. A reciprocating reset rod 11 is fixedly connected to the middle of the upper limiting plate 8. An inner bearing 12 is provided at the lower end of the reciprocating reset rod 11. An outer bearing 13 is fixedly connected to the outer ring of the inner bearing 12. The outer ring of the outer bearing 13 is fixedly connected to the middle of the pair of sliding plates 10. A connecting block 14 is fixedly connected to the lower end of the inner bearing 12. A lead screw 15 is fixedly connected to the lower end of the connecting block 14. A roller pressing drive assembly 16 is provided in the middle of the lead screw 15. A vibration-type de-bubbling roller pressing assembly 17 and a fixed small roller pressing assembly 18 are provided at the lower end of the roller pressing drive assembly 16. The outer casing 1 provides overall protection for all internal components, and the heat dissipation plate 2 quickly dissipates the heat generated during equipment operation, preventing high temperatures from affecting equipment stability. The servo motor 4 provides the sole power source, driving the active bevel gear 5 and the reciprocating drive turntable 6 to operate synchronously. Relying on the limiting sliding structure composed of the fixed plate 7, the limiting plate 8, the limiting rod 9, and the sliding plate 10, the reciprocating reset rod 11 achieves stable vertical reciprocating motion of the roller pressing structure. Then, through the connecting block 14, the linkage screw 15 and the roller pressing drive assembly 16 synchronously drive the vibration de-bubbling roller pressing assembly 17 and the fixed small roller pressing assembly 18 to work. It integrates reciprocating roller pressing, vibration de-bubbling, and fine trimming functions, simplifying the equipment's power structure.

[0023] The reciprocating drive turntable 6 is composed of an inner fixed disc 61, an outer fixed ring 62, a small ring 63, and a large ring 64. The middle part of the inner fixed disc 61 is fixedly connected to the inside of the outer fixed ring 62. The middle part of the outer fixed ring 62 is fixedly connected to the small ring 63 and the large ring 64. The diameter of the large ring 64 is larger than the diameter of the small ring 63, and the ratio is 3:1. The turntable is stably assembled as a whole by the inner fixed disc 61 and the outer fixed ring 62. The small ring 63 and the large ring 64 with a diameter ratio of 3:1 form a differentiated drive stroke, which can realize the reciprocating motion with height difference.

[0024] The reciprocating reset rod 11 includes a reset outer sleeve 111, a reset spring 112 is installed inside the reset outer sleeve 111, a sliding rod 113 is slidably connected inside the reset outer sleeve 111, the middle part of the reset outer sleeve 111 is fixedly connected to the middle part of the upper limit plate 8, and the lower end of the sliding rod 113 is fixedly connected to the inner ring of the inner bearing 12. The overall structure is fixed by the reset sleeve 111, which provides limit protection for the internal reset spring 112. When the roller pressing structure is in downward operation, the sliding rod 113 is compressed and the reset spring 112 stores elastic potential energy. This, together with the inner bearing 12 and the outer bearing 13, buffers the rigid impact force of the roller pressing downward, preventing the blank from being damaged by pressure. After the roller pressing operation is completed, the reset spring 112 releases its elastic force, pushing the sliding rod 113 and the connecting block 14 below, the lead screw 15 and the entire roller pressing structure to quickly reset, realizing continuous cyclic reciprocating roller pressing action, ensuring the continuity and stability of the operation.

[0025] The roller pressing drive assembly 16 includes a fixed bracket 161 fixedly connected to one end of the receiving frame 3. A rotating sleeve 162 is fixedly connected to one end of the fixed bracket 161. A rotating shaft 163 is rotatably connected inside the rotating sleeve 162. A bolt connecting disc 164 is fixedly connected to the lower end of the rotating shaft 163. A drive gear 165 and a driven bevel gear 166 are fixedly connected to the upper end of the rotating shaft 163. A receiving strip 167 is also rotatably connected to the upper end of the rotating shaft 163. One end of the receiving strip 167 is fixedly connected to the upper end of the fixed bracket 161. The fixed bracket 161 and the receiving strip 167 provide stable support for the overall structure. The rotating sleeve 162 limits and guides the rotating shaft 163 to ensure stable rotation. The driven bevel gear 166 meshes with the active bevel gear 5 to receive power from the servo motor 4, driving the rotating shaft 163 and the active gear 165 to rotate synchronously. On the one hand, the active gear 165 drives the vibration-type de-bubbling roller pressing assembly 17 to work. On the other hand, the fixed small roller pressing assembly 18 can be detachably assembled through the lower bolt connecting plate 164, realizing flexible switching between the two roller pressing modes. A single power source completes the driving of multiple structures, reducing equipment energy consumption and manufacturing costs.

[0026] The vibratory de-bubbling roller pressing assembly 17 includes an outer roller pressing mold 171 rotatably connected to the other end of a fixed bracket 161. Multiple scraping plates 172 are slidably connected to the middle of the outer roller pressing mold 171. A buffer spring 173 is fixedly connected to the upper end of each of the multiple scraping plates 172. The upper end of the buffer spring 173 is fixedly connected to the inner wall of the outer roller pressing mold 171. A driven gear 174 is fixedly connected to the upper end of the outer roller pressing mold 171. The driven gear 174 meshes with the driving gear 165. A fixed outer shell 175 is fixedly connected inside the outer roller pressing mold 171. A fixed ring 176 is fixedly connected inside the fixed outer shell 175. A receiving bearing 177 is fixedly connected inside the fixed ring 176. A threaded sleeve 178 is fixedly connected to the inner ring of the receiving bearing 177. Multiple biasing vibration blocks 179 are fixedly connected to the middle of the threaded sleeve 178. The threaded sleeve 178 is threadedly connected to the lead screw 15. The outer mold 171 is driven to rotate by the meshing of the drive gear 165 and the driven gear 174 to complete the large-area rolling operation of the billet. The vertical reciprocating motion of the lead screw 15 forms a threaded transmission with the screw sleeve 178. The screw sleeve 178 is stably rotated by the bearing 177 and the fixing ring 176, which drives the multiple sets of eccentric vibration blocks 179 on the outside of the screw sleeve 178 to rotate at high speed, generating high-frequency micro-vibrations, which are transmitted to the outer mold 171 through the fixed shell 175. During the rolling process, the micro-bubbles inside the billet are dispersed and discharged, eliminating the pore defects of the billet. The scraping plate 172 is pushed by the buffer spring 173 to keep it in contact with the surface of the billet. It automatically scrapes off the excess mud material in sync with the rotation of the outer mold 171, realizing the integrated operation of rolling, defoaming and trimming.

[0027] The fixed small roller pressing assembly 18 includes a small roller pressing mold 181. A connecting bolt disc 182 is fixedly connected to the upper end of the small roller pressing mold 181. The connecting bolt disc 182 is fixedly connected to the bolt connecting disc 164 by bolts. A ball 183 is placed inside the small roller pressing mold 181. The small roller pressing die 181 can be quickly disassembled and replaced by the connection of the bolt disc 182 and the bolt connection disc 164. The disassembly and assembly are convenient and the maintenance is easy. The roller pressing adaptability of the die is improved by the round ball 183 set inside the small roller pressing die 181. It can perform fine small-range roller pressing repair on the local unevenness and edge defects of the blank, and is suitable for processing smaller blanks.

[0028] Among them, the middle part of the receiving frame 3 is provided with a cross groove, and the lifting rod E2 and the rotating rod E1 can be slidably connected in the cross groove. The rotating rod E1 is composed of a cross rod and a bolt plate, and the lifting rod E2 is composed of a cross rod and a flat bolt plate. The cross groove in the middle of the receiving frame 3 provides a suitable installation position for the rotating rod E1 and the lifting rod E2. The rotating rod E1 or the lifting rod E2 can be flexibly switched according to production needs to realize two transmission modes of pure vertical lifting roller pressing and rotary roller pressing, respectively, which can adapt to the forming process requirements of different ceramic blanks and greatly improve the versatility and processing flexibility of the equipment.

[0029] The outer roller mold 171 has a hollow interior, a circular lower end, and an annular groove that is rotatably connected to the fixed bracket 161 at the upper end. The hollow structure of the outer roller pressing mold 171 reduces its own weight, thereby reducing the equipment drive load and operating energy consumption. The circular structure at the lower end of the outer roller pressing mold 171 ensures that the roller pressing contact surface is subjected to uniform force, avoiding excessive local pressure that could damage the blank. The annular groove at the upper end of the outer roller pressing mold 171 cooperates with the fixed bracket 161 to achieve precise limiting rotation of the mold.

[0030] The outer roller die 171 has multiple rectangular sliding grooves in the middle that are slidably connected to the scraper 172. The scraping plate 172 is precisely positioned and guided by the rectangular sliding groove in the middle of the outer roller mold 171, which restricts the scraping plate 172 to slide vertically along the groove. This effectively prevents the scraping plate 172 from shifting, tilting or getting stuck during operation, ensuring that the scraping plate 172 can extend and retract smoothly and stably, and continuously adhere to the blank to complete the scraping and trimming operation.

[0031] The lower end of the scraper 172 is set at an angle; The inclined blade structure at the lower end of the scraper 172 greatly reduces scraping resistance, allowing for smooth cutting and scraping of excess mud and protruding impurities from the edges and corners of the blank.

[0032] Working principle and usage process: When the equipment is running, the operation mode is first selected according to the processing requirements of the ceramic blank. When the overall large surface defoaming and regularization processing is carried out, the vibration defoaming roller pressing component 17 is retained. When the local fine finishing processing is carried out, the fixed small roller pressing component 18 is fixedly assembled with the bolt connecting plate 164 through the connecting bolt plate 182, and the component switching installation is completed. After the equipment is started, the servo motor 4 starts running, driving the active bevel gear 5 and the reciprocating drive turntable 6 at the output end to rotate synchronously. The active bevel gear 5 meshes with the driven bevel gear 166 to drive the rotating shaft 163 to rotate stably inside the rotating sleeve 162. The rotating shaft 163 drives the active gear 165 at the upper end to rotate synchronously. The active gear 165 meshes with and drives the driven gear 174 to rotate, thereby driving the outer rolling die 171 to rotate as a whole, realizing the rotating rolling operation on the surface of the blank. During the rotation of the reciprocating drive turntable 6, the sliding limit structure composed of the limit rod 9 and the sliding plate 10 drives the lead screw 15, connecting block 14, and bearing structure to move vertically back and forth along the limit rod 9, realizing the up and down reciprocating rolling action of the roller pressing structure. During the downward rolling process, the sliding rod 113 is compressed and the reset spring 112 inside the reset sleeve 111 is compressed, storing elastic potential energy. When the roller presses upward, the reset spring 112 releases the elastic force, pushing the sliding rod 113 and the overall roller pressing structure to reset, realizing continuous reciprocating rolling processing. While the lead screw 15 moves vertically, it forms a threaded transmission with the screw sleeve 178, driving the screw sleeve 178 to rotate in the inner ring of the receiving bearing 177. The screw sleeve 178 drives the multiple eccentric vibration blocks 179 fixed on the outside to rotate at high speed eccentrically, continuously generating high-frequency micro-vibration. The vibration is transmitted to the outer mold 171 of the roller pressing through the fixed outer shell 175. During the rolling, the blank is vibrated to disperse and discharge the tiny air bubbles trapped inside the blank, eliminating the pores and voids inside the blank. During the rotation of the outer roller pressing mold 171, the scraper 172 inside it always adheres to the roller pressing surface of the blank under the elastic action of the buffer spring 173 and rotates synchronously with the mold. The scraper removes the excess edge mud and surface protrusions of the blank under pressure in real time through the lower inclined surface, and automatically completes the edge trimming and leveling of the blank. When switching to the fixed small roller pressing assembly 18, the small roller pressing mold 181 is rotated by the rotating shaft 163 to perform fine roller pressing on the uneven parts of the blank, which is suitable for small-scale, high-precision blank forming processing needs. During the operation of the equipment, the heat conduction plate 2 in the middle of the outer shell 1 continuously dissipates the heat generated by the internal operation of the equipment, ensuring long-term stable operation of the equipment. The cross groove of the receiving frame 3 can be switched to install the rotating rod E1 and the lifting rod E2 as needed, to adapt to different roller pressing transmission and lifting adjustment needs, further improving the processing adaptability and flexibility of the equipment. The entire set of equipment realizes multiple functions such as reciprocating roller pressing, rotary flattening, vibration defoaming, and automatic scraping through a single servo motor 4. It does not require multiple power sources, has strong structural linkage, and can effectively improve the density and regularity of ceramic blank roller pressing, avoiding defects such as cracking and bulging of finished products after sintering.
