Description

Technical Field

[0001] This utility model relates to the field of ceramic heater production technology, and in particular to a ring-shaped ceramic heater forming device. Background Technology

[0002] In modern industrial production, ceramic heaters are increasingly widely used, playing a vital role, especially in heating, drying, and heat preservation. To meet market demands and improve production efficiency, the development of new ceramic heater production equipment is of paramount importance.

[0003] A circular ceramic heater forming device disclosed in Chinese Patent Publication No. CN222494760U can locate the positions of the semi-forming upper mold, fixture, and pressing mold by setting the workstation positions and sensors. This facilitates the controller to control the operation of the drive components, enabling the semi-forming upper mold, fixture, and pressing mold to accurately fit with the bottom mold. However, according to ceramic heater forming devices and existing technologies in related fields, traditional devices mostly use motor-driven rotation and sensor (such as encoders and proximity switches) for workstation positioning. This requires a complex control system, and electrical components account for a large proportion of the total equipment cost. Furthermore, debugging and maintenance require professional technicians, increasing the company's labor costs. The sensors are also susceptible to interference from dust and temperature (ceramic production environments often reach high temperatures), leading to positioning errors or machine shutdowns (e.g., ceramic dust covering the sensor surface, causing false signal triggering). If the sensor malfunctions or the program errs, manual reset or adjustment of the workstation is required, affecting the continuity of production. Utility Model Content

[0027] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, in part of which will be obvious from the description or may be learned by practice of the invention.

[0028] like Figures 1 to 11 As shown, a ring-shaped ceramic heater forming device includes a worktable 1 and a forming component 2. The top of the worktable 1 is provided with an adjustment component 3 for controlling the lifting and lowering of the forming component 2, and a circulating rotation component 4 is provided on the adjustment component 3. A bottom mold 5 and a storage tray 6 are symmetrically fixedly installed on the top of the worktable 1. The forming component 2 includes a mounting shaft 201, and a bracket 202 is fixedly installed at the bottom end of the mounting shaft 201. A clamp 203, a semi-forming upper mold 204, a first pressing mold 205 and a second pressing mold 206 are fixedly installed at equal intervals at the bottom of the bracket 202. A plurality of guide components 7 are provided at equal intervals on the outer surface of the mounting shaft 201. By utilizing the cooperation between the guide components 7 and the circulating rotation component 4, the forming component 2 can rotate 90 degrees in one direction when lifting and lowering.

[0029] The circulating rotating assembly 4 includes a fixed cylinder 401. Four V-shaped guide grooves 402 are evenly spaced on the inner wall of the fixed cylinder 401. A straight groove 403 is formed below each V-shaped guide groove 402 on the fixed cylinder 401. The straight groove 403 is located in the middle of the V-shaped guide groove 402 and is connected to it. A first positioning groove 404 is formed on one side of the connection between the straight groove 403 and the V-shaped guide groove 402. The interior of the first positioning groove 404 is ferroelectrically connected to the straight groove 403. The first guide block 405 is hinged to the pivot of the elastic element. A second positioning groove 406 is provided at the position where two adjacent V-shaped guide grooves 402 are connected. The second guide block 407 is hinged to the interior of the second positioning groove 406 through the pivot of the elastic element. The first positioning groove 404 is used to make the first guide block 405 only able to flip into the interior of the straight groove 403. The second positioning groove 406 is used to make the second guide block 407 only able to flip into the interior of the other V-shaped guide groove 402.

[0030] The guide assembly 7 includes a fixing rod 701 fixedly mounted on the outer surface of the mounting shaft 201. A roller 702 is rotatably mounted on the end of the fixing rod 701 away from the mounting shaft 201. The roller 702 is adapted to the V-shaped guide groove 402 and the straight groove 403. Figures 5 to 11 As shown, when the molding component 2 descends, the fixed rod 701 and roller 702 cooperate with the V-shaped guide groove 402 to rotate while descending. When the fixed rod 701 and roller 702 enter the straight groove 403, the first guide block 405 is pressed into the first positioning groove 404. At this time, the molding component 2 has rotated 45°. After the fixed rod 701 and roller 702 enter the straight groove 403, the elastic element shaft can cause the first guide block 405 to spring back to its original position. When the molding component 2 rises, the first guide block 405 can guide the fixed rod 701 and roller 702 to move towards the other half of the V-shaped guide groove 402, so that the molding component 2 can only rotate in one direction. When the fixed rod 701 and roller 702 enter the other V-shaped guide groove... At position 402, the second guide block 407 is pressed into the second positioning groove 406, at which point the forming component 2 has rotated 90°. When the forming component 2 descends again, the second guide block 407 guides the fixed rod 701 and roller 702 to move into another V-shaped guide groove 402, preventing them from retracting into the previous V-shaped guide groove 402, thus allowing the forming component 2 to rotate only in one direction. The station switching is achieved through a purely mechanical structure, avoiding the complex configuration of motors, sensors, and control systems in traditional automated equipment, reducing the cost of purchasing, debugging, and maintaining electronic components. It is especially suitable for small and medium-sized enterprises or cost-sensitive production lines. Mechanical components typically have higher anti-interference capabilities and stability, reducing the risk of downtime due to electrical faults and extending the service life of the equipment.

[0031] like Figure 1 As shown, the adjustment assembly 3 includes a mounting bracket 301 fixedly installed on the top of the workbench 1. A hydraulic cylinder 302 is fixedly installed on the top of the mounting bracket 301. The output end of the hydraulic cylinder 302 passes through the mounting bracket 301. The top end of the mounting shaft 201 is fixedly connected to the output end of the hydraulic cylinder 302. A support arm 4011 is fixedly provided on the outer surface of the fixed cylinder 401. The end of the support arm 4011 away from the fixed cylinder 401 is fixedly connected to the mounting bracket 301.

[0032] The work process is as follows:

[0033] S1: When the hydraulic cylinder 302 controls the molding component 2 to descend, the fixed rod 701 and roller 702 cooperate with the V-shaped guide groove 402 to make the molding component 2 rotate while descending. When the fixed rod 701 and roller 702 enter the straight groove 403, the first guide block 405 will be pressed into the first positioning groove 404. At this time, the molding component 2 rotates 45°. After the fixed rod 701 and roller 702 enter the straight groove 403, the elastic element shaft can cause the first guide block 405 to spring back and reset.

[0034] S2: When the hydraulic cylinder 302 controls the molding component 2 to rise, the first guide block 405 can guide the fixed rod 701 and the roller 702 to move to the other half of the V-shaped guide groove 402, so that the molding component 2 can only rotate in one direction. When the fixed rod 701 and the roller 702 enter the other V-shaped guide groove 402, the second guide block 407 will be pressed into the second positioning groove 406. At this time, the molding component 2 has just rotated 90°.

[0035] S3: When the hydraulic cylinder 302 controls the molding component 2 to descend again, the second guide block 407 can be used to guide the fixed rod 701 and the roller 702 to move into another V-shaped guide groove 402, so that they cannot return to the previous V-shaped guide groove 402, thus making the molding component 2 only able to rotate in one direction.

[0036] S4: In summary, by adjusting component 3, the semi-finished upper mold 204 is made to cooperate with the bottom mold 5 to complete the pressing of the semi-finished product; then, the clamp 203 cooperates with the bottom mold 5 under the action of adjusting component 3 to place the heating coil; finally, the first pressing mold 205 and the second pressing mold 206 cooperate with the bottom mold 5 under the action of adjusting component 3 to complete the pressing and forming of the finished product.

[0037] S5: It achieves workstation switching through a purely mechanical structure, avoiding the complex configuration of motors, sensors and control systems in traditional automated equipment, reducing the cost of purchasing, debugging and maintenance of electronic components, and is especially suitable for small and medium-sized enterprises or cost-sensitive production lines.

[0038] S6: After the first molding part 205 completes the initial shaping, the second molding part 206 performs a second precision pressing, which can correct problems such as dimensional deviation and uneven filling density during the initial pressing. For brittle materials such as ceramics, the second pressing can reduce internal pores and cracks, improve the density of the product, and thus enhance the thermal conductivity and mechanical strength of the heater.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
