Description

Technical Field

[0001] This utility model belongs to the field of ceramic sheet processing technology, specifically, it relates to tooling for precision ceramic sheet processing. Background Technology

[0002] When processing precision ceramic sheet parts, it is generally necessary to put the mixed powder into the mold cavity, and then use a pressure device in conjunction with the mold cavity to extrude the ceramic powder into shape. After shaping, a pusher plate pushes the shaped workpiece out of the mold cavity.

[0003] In the production process of precision ceramic sheet parts, traditional processing equipment usually adopts a single-station design, that is, feeding, forming and discharging are carried out in the same station in sequence. Since feeding, forming and discharging need to be completed in sequence, the equipment is idle when feeding and discharging, which leads to a longer production cycle and makes it difficult to meet the needs of mass production.

[0004] In view of the above problems, a tooling for machining precision ceramic sheet parts is proposed here. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0027] Example: Refer to Figures 1-6A precision ceramic sheet processing fixture includes a base 1 and a first mounting bracket 11 fixedly mounted on the base 1. It also includes: a rotary drive table mounted on the base 1, on which three sets of lower molds 7 for feeding, forming, and discharging are respectively arranged, and these three sets of lower molds 7 are circumferentially and equidistantly distributed; a pressing component is fixedly mounted on the first mounting bracket 11, and an upper mold 6 is fixedly mounted on the output end of the pressing component. When the lower mold 7 moves directly below the upper mold 6, the pressing component drives the upper mold 6 to descend and couple with the lower mold 7; a feeding machine 52 is mounted on the pressing component, and when the lower mold 7 moves directly below the feeding machine 52, the feeding machine 52 discharges material into the lower mold 7; and a discharging component is mounted on the base 1.

[0028] During operation, the rotary drive table drives the lower mold 7 to rotate and move, passing through the loading position, compression molding position and discharge position in sequence.

[0029] In this embodiment, at least three lower molds 7 are provided. Taking one of the lower molds 7 as an example, after the lower mold 7 moves to the feeding position, the feeding machine 52 discharges material into the lower mold 7. After the feeding is completed, the lower mold 7 moves to the lower mold 6. Then, the pressing component drives the upper mold 6 to descend and merge with the lower mold 7. During the merging process, the raw material is extruded and formed. Then the upper mold 6 and the lower mold 7 separate. After separation, the lower mold 7 is transferred to the discharge position for material discharge. With the design of three sets of lower molds 7, this processing step can realize feeding, forming and discharge simultaneously, thereby improving the processing efficiency of ceramic plate production.

[0030] Reference Figure 2 and Figure 3 The rotary drive table includes a mounting column 3 fixedly mounted on a base 1, a mounting plate 31 rotatably mounted on the mounting column 3, a lower mold 7 fixedly mounted on the mounting plate 31, and a motor 32 fixedly mounted on the base 1. The output rotor of the motor 32 is connected to the mounting plate 31 through a gear set 33.

[0031] When in use, the motor 32 is started, and the motor 32 drives the mounting plate 31 to rotate through the gear set 33. In this embodiment, the motor 32 drives the mounting plate 31 to rotate 120° each time, thereby realizing the precise switching of the lower mold 7 on three work stations.

[0032] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The upper mold 6 includes a forming pressure block 61 fixedly installed at the bottom. The lower mold 7 has a forming groove 74 at the top. When the upper mold 6 and the lower mold 7 are combined, the forming pressure block 61 is inserted into the forming groove 74. The lower mold 7 has an installation groove 71. An installation plate 72 is slidably installed in the installation groove 71. A forming top block 73 is fixedly installed on the installation plate 72. The forming top block 73 is slidably connected in the forming groove 74. The bottom of the lower mold 7 and the installation plate 31 have a through hole 75 that communicates with each other. The pressing component includes a second electric hydraulic cylinder 5 fixedly installed on the first mounting bracket 11. The output end of the second electric hydraulic cylinder 5 is fixedly connected to the upper mold 6. A first electric hydraulic cylinder 2 is fixedly installed on the base 1. The first electric hydraulic cylinder 2 and the second electric hydraulic cylinder 5 are coaxially arranged. A first top block 21 is fixedly installed on the top of the first electric hydraulic cylinder 2. The first top block 21 is driven to move to the mounting plate 72 below the upper mold 6 and rise.

[0033] In this embodiment, after the lower mold 7 moves directly below the upper mold 6, the second electric hydraulic cylinder 5 drives the upper mold 6 to descend, causing the forming pressure block 61 to insert into the forming groove 74. At the same time, the first electric hydraulic cylinder 2 drives the first top block 21 to rise, and the first top block 21 drives the forming top block 73 to rise through the mounting plate 72. During this process, with the cooperation of the forming top block 73, the forming pressure block 61, and the forming groove 74, the powder raw material is compressed into a plate.

[0034] In this embodiment, by designing the second electric hydraulic cylinder 5 and the first electric hydraulic cylinder 2 to be coaxial, the force application directions of the forming pressure block 61 of the upper mold 6 and the forming top block 73 of the lower mold 7 are precisely aligned, avoiding the lateral component force caused by eccentric load. This alignment can ensure that the powder raw material is subjected to uniform force during the compression process, reducing the risk of uneven density or delamination defects inside the ceramic plate.

[0035] Reference Figure 1 and Figure 2 A second mounting bracket 51 is fixedly installed on the side wall of the output end of the second electric hydraulic cylinder 5, and the feeding machine 52 is fixedly installed on the second mounting bracket 51.

[0036] When the second electric hydraulic cylinder 5 drives the upper mold 6 to descend, the upper mold 6 simultaneously drives the second mounting bracket 51 to descend, and the second mounting bracket 51 drives the feeder 52 to descend, thereby extending the discharge port of the feeder 52 into the forming groove 74 for material discharge.

[0037] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6A piston cylinder 8 is fixedly installed on the base 1. The piston cylinder 8 is "T" shaped. A piston drive rod 83 is slidably installed on the vertical tube of the piston cylinder 8. The piston drive rod 83 is fixedly connected to the second mounting bracket 51. A piston push rod 81 is slidably installed on the horizontal tube of the piston cylinder 8. A pusher plate 82 is fixedly installed on the output end of the piston push rod 81. An installation ring 4 is fixedly installed on the side wall of the output end of the first electric hydraulic cylinder 2. A second top block 41 and a third top block 42 are fixedly installed on the top of the installation ring 4. A weighing sensor 43 is fixedly installed on the second top block 41. The weighing sensor 43 is located below the feeder 52.

[0038] Both the piston drive rod 83 and the piston push rod 81 are composed of a piston plate and a piston rod.

[0039] As the second mounting bracket 51 descends, the first electric hydraulic cylinder 2 drives the mounting ring 4 to rise. The mounting ring 4 drives the second top block 41 and the third top block 42 to rise. The second top block 41 drives the forming top block 73 (discharge position) to rise, so that the top surface of the forming top block 73 is at the same level as the top surface of the lower mold 7 (discharge position). The second mounting bracket 51 drives the piston drive rod 83 to descend. Under the action of the driving medium (preferably hydraulic oil) in the piston cylinder 8, the piston push rod 81 is driven to extend. The extended piston push rod 81 drives the pusher plate 82 to translate. When the top surface of the forming top block 73 is at the same level as the top surface of the lower mold 7, the pusher plate 82 contacts the plate and then continues to move to push the plate away from the forming top block 73, automatically detaching the plate.

[0040] When the mounting ring 4 rises, it drives the weighing sensor 43 to rise. After the weighing sensor 43 comes into contact with the mounting plate 72 (feeding position), it drives the mounting plate 72 to rise. In this embodiment, the control host has the weight data of the mounting plate 72 and the forming top block 73. The weighing sensor 43 returns to zero after lifting the mounting plate 72 and the forming top block 73. If the value obtained after lifting the mounting plate 72 and the forming top block 73 is less than zero, it indicates that the weighing sensor 43 is abnormal or that some component in the mounting plate 72 and the forming top block 73 is damaged. When the value is greater than zero, it indicates that the weighing sensor 43 may be abnormal or that there is powder residue on the forming top block 73. When there is powder residue, it indicates that there is a problem with the entire processing fixture. When a problem is detected, the alarm in the control host will sound.

[0041] In addition, during the feeding process, the weighing sensor 43 can also detect whether the material in the forming tank 74 has reached the set addition threshold, thereby improving the feeding accuracy and thus improving the accuracy of the final produced plate.

[0042] In summary, this tooling has the following advantages:

[0043] The rotating drive table enables simultaneous operation of three stations: feeding, forming, and discharging. The three lower molds 7 are distributed at 120° intervals. The motor 32 drives the mounting plate 31 to precisely rotate and switch stations, significantly improving production efficiency. Compared with traditional single-station forming equipment, this design can reduce idle time during feeding and discharging, and improve the production efficiency of ceramic sheet parts.

[0044] The first electric hydraulic cylinder 2 and the second electric hydraulic cylinder 5 are designed to be coaxial, ensuring that the forming pressure block 61 of the upper mold 6 and the forming top block 73 of the lower mold 7 are strictly aligned in the direction of force application, avoiding lateral force caused by eccentric load, improving compression uniformity, thereby reducing defects such as layering or uneven density of ceramic blanks and extending mold life, such as reducing wear on the forming pressure block 61 and forming groove 74.

[0045] On the one hand, the feeding machine 52 descends in conjunction with the upper mold 6 through the second mounting frame 51 to achieve automatic and accurate material discharge. On the other hand, the weighing sensor 43 monitors the weight of the powder in real time to ensure feeding accuracy and avoid overfeeding or underfeeding. In addition, the weighing sensor 43 can also detect abnormalities in the mounting plate 72 (such as residual powder or component damage) and trigger an alarm to improve production reliability.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
