[0002] The composite pot bottom is formed by combining two or more materials. The current mainstream composite processes include solid phase composite technology, liquid phase composite technology and gas phase composite technology. During long-term use, the composite pot bottom will separate due to the different expansion coefficients of the layered materials caused by alternating hot and cold temperatures.

[0029] See also Figure 1-Figure 7, a composite pot bottom assembly device, comprising a composite pot bottom 1 and a deformable anchor 12 to be assembled, the composite pot bottom 1 comprising a first layer 13, a second layer 14 and a third layer 15 which have been composited together, a countersunk hole 11 is provided on the bottom surface of the composite pot bottom 1, a step cavity 111 is provided at the end of the countersunk hole 11, the diameter of the step cavity 111 is greater than the diameter of the countersunk hole 11, the countersunk hole 11 passes through the first layer and the second layer, the end of the countersunk hole 11 is located in the third layer, and the step cavity 111 is located in the third layer, the deformable anchor 12 comprises a tail 122, a rod 123 and a deformable portion 124, the tail 122 is conical, a conical hole adapted thereto is provided at the position of the countersunk hole 11 of the first layer, so that after the deformable anchor 12 is fully installed, the tail 122 is located in the conical hole for hiding, the deformable portion 124 is a petal inclined outwardly, and a plurality of them are evenly arranged, after the deformable anchor 12 is inserted into the countersunk hole 11.

[0030] In the absence of pressure, the top of the deformation portion 124 touches the bottom surface of the countersunk hole 11, and the tail portion 122 exceeds the bottom surface of the composite pot bottom 1. When pressure is applied to the deformation anchor 12, the deformation portion 124 deforms and bends outward, and the folded position is inserted into the step cavity 111, thereby riveting the deformation anchor 12 in the countersunk hole 11.

[0031] The device includes a base frame, on which a melting tank 3 is arranged, and a vacuum tank 2 is arranged at the upper end of the melting tank 3. The melting tank 3 contains molten liquid metal. The upper end of the melting tank 3 is covered by the bottom plate of the vacuum tank 2, and a piston plate 31 is arranged in the melting tank 3. The front end of the piston plate 31 and the bottom surface of the vacuum tank 2 form a vacuum chamber, and the vacuum chamber contains metal liquid. The forward and backward movement of the piston plate 31 can change the height of the metal liquid level in the vacuum chamber, and the rear end of the piston plate 31 is connected to an electric telescopic component 32, which can accurately control the movement displacement of the piston plate 31.

[0032] The vacuum tank 2 includes a tank body 21 fixedly arranged on the melting tank 3 and a tank cover 22 matched with the tank body 21, a guide rod 24 is arranged on the base frame, a sliding member 25 is arranged on the guide rod 24 for guiding, the tank cover 22 is elastically slidably arranged on the sliding member 25, and a hydraulic member 26 is arranged on the sliding member 25, the hydraulic member 26 controls the sliding member 25 to move up and down, and then controls the tank cover 22 to be combined with or separated from the tank body 21.

[0033] A sliding rod 222 is provided on the upper end surface of the tank cover 22, and is slidably configured on the sliding member 25 through the guidance of the sliding rod 222. A first elastic member 223 is configured on the sliding rod 222. One end of the first elastic member 223 is configured to contact the upper end surface of the sliding member 25, and the other end contacts the limit block on the sliding rod 222.

[0034] An elastic seal 224 is arranged on the bottom surface of the tank cover 22. When the tank cover 22 is arranged on the tank body 21, the elastic seal 224 is pressed and then undergoes a small elastic deformation. When the vacuum tank 2 is evacuated to a vacuum, the tank cover 22 moves further downward, and at the same time, the elastic seal 224 undergoes a large elastic deformation. The tank cover 22 is elastically slidably arranged on the sliding member 25 to provide support for the downward movement of the tank cover 22.

[0035] A channel cavity is provided on the bottom surface of the tank body 21, and a fluid channel connected to the melting tank 3 is provided on the side of the channel cavity, and a positioning column 211 is slidably arranged on the channel cavity, and a sliding rod 23 is slidably arranged in the bottom plate of the tank body 21, and one end of a rotating rod 231 is rotatably arranged on the sliding rod 23, and the other end of the rotating rod 231 is rotatably arranged on the bottom surface of the positioning column 211. The sliding rod 23 moves back and forth, and the positioning column 211 can be driven to move back and forth through the transmission of the rotating rod 231. An electric telescopic rod is connected to the sliding rod 23, and the electric telescopic rod drives the sliding rod 23 to move back and forth, thereby controlling the positioning column 211 to move up and down, and a positioning pin is provided on the upper end of the positioning column 211, and the positioning pin is adapted to the positioning through hole 121 on the deformation anchor 12.

[0036] Its working principle or usage is as follows: In the initial state, a release agent is sprayed in the tank body 21, and then the deformation anchor 12 is invertedly inserted on the positioning pin through the positioning through hole 121 by a robot or manually. At this time, the deformation part 124 of the deformation anchor 12 faces upward, and the robot aligns the countersunk hole 11 of the composite pot bottom 1 with the positioning pin and inserts it on the positioning column 211. At this time, under the action of the gravity of the composite pot bottom 1 itself, the top end of the deformation part 124 touches the bottom end surface of the countersunk hole 11, and the tail end of the deformation anchor 12 The portion 122 is located on the outside of the composite pot bottom 1, and because the diameter of the tail portion 122 on the deformation anchor 12 is larger than the diameter of the positioning column 211, the tail portion 122 of the deformation anchor 12 is pressed against the upper end surface of the positioning column 211 and the bottom surface of the tank body 21 at the same time. Since the deformation anchor 12 is not fully inserted into the countersunk hole 11, there is a gap between the composite pot bottom 1 and the bottom surface of the tank body 21, which makes it easier for the countersunk hole 11 to be evacuated to a vacuum during the vacuum process.

[0037] At this time, the hydraulic component 26 controls the sliding component 25 to move downward, controls the tank cover 22 to be combined with the tank body 21, and a pressing component 221 is arranged on the lower end surface of the tank cover 22. When the tank cover 22 is combined with the tank body 21, the pressing component 221 just presses on the upper end surface of the composite pot bottom 1. At this time, the vacuum generator starts to work, and the vacuum tank 2 is evacuated to a vacuum state. In the process of evacuating to a vacuum state, the air in the countersunk hole 11 is also evacuated through the surrounding gaps, so the countersunk hole 11 is also in a vacuum state. At the same time, in the process of evacuating to a vacuum state, under the action of atmospheric pressure, the tank cover 22 moves downward, and then the pressing component 221 drives the composite pot bottom 1 to move downward, while the deformation anchor 12 remains stationary, and then under the action of pressure, the deformation portion 124 at the upper end of the deformation anchor 12 is deformed and bent and inserted into the step cavity 111, so that the deformation anchor 12 is riveted in the countersunk hole 11.

[0038] After the vacuum tank 2 is evacuated to a vacuum, the heating unit at the bottom of the tank body 21 starts to work, heating the bottom of the tank body 21 to the same temperature as that in the melting tank 3. At this time, the electric telescopic rod on the sliding rod 23 starts to shrink, thereby driving the positioning column 211 to move downward, so that the channel cavity is connected with the fluid channel, and then the melting tank 3 is connected with the bottom of the deformation anchor 12. Since the bottom surface of the composite pot bottom 1 is tightly attached to the bottom surface of the tank body 21 at this time, the channel cavity is covered by the bottom surface of the deformation anchor 12.

[0039] At this time, the electric telescopic part 32 controls the piston plate 31 to move, pushing the molten metal liquid from the fluid channel into the positioning through hole 121 at the bottom of the deformation anchor 12, and then directly into the countersunk hole 11. At the same time, the countersunk hole 11 is in a vacuum state, and the metal liquid can be quickly absorbed to fill the empty space in the countersunk hole 11.

[0040] After the electric telescopic rod 32 is extended to the set position, the electric telescopic rod on the sliding rod 23 begins to extend, thereby driving the positioning column 211 to move upward, and the positioning column 211 blocks the channel cavity. At this time, the heating unit at the bottom of the tank body 21 stops heating, so that the temperature at the bottom of the tank body 21 drops, and the molten metal in the counterbore 11 solidifies, and the vacuum state of the vacuum tank 2 is simultaneously released. After the vacuum tank 2 returns to normal pressure, the hydraulic component 26 controls the sliding component 25 to move upward, and the tank cover 22 is separated from the tank body 21. Due to the spraying of the release agent, the molten metal will not stick to the bottom surface of the vacuum tank 21 and the positioning column 211 after solidification, so the robot can quickly take out the assembled composite pot bottom 1.

[0041] Embodiment 2:

[0042] This embodiment makes the following further improvements on the basis of embodiment 1, see Figure 1-Figure 7After the composite pot bottom 1 is taken out, the heating unit in the tank body 21 starts working again, and the metal remaining on the positioning column 211 and the bottom surface of the tank body 21 is melted into liquid metal again. The robot controls the cleaning device to enter the tank body 21 to perform negative pressure cleaning on the residual liquid metal in the tank body. After the cleaning is completed, the heating unit stops working again, and the robot sprays the release agent on the inner wall of the tank body 21 again.

[0043] The molten metal is preferably a zinc-aluminum alloy, and its melting temperature is controlled between 350-450 degrees Celsius.

[0044] Embodiment 3:

[0045] This embodiment makes the following further improvements on the basis of embodiment 1, see Figure 1-Figure 7 A plurality of countersunk holes 11 are evenly arranged on the bottom surface of the composite pot bottom 1, and the countersunk holes 11 are distributed in a circle, and a positioning column 211 adapted to the countersunk holes 11 is arranged on the pot bottom 21, and the positioning column 211 on each radius line is provided with a sliding rod 23, and the sliding rod 23 is connected to the positioning column 211 on this radius line through a rotating rod 231, so that the composite fulcrum of the composite pot bottom 1 is more uniform and firm.
