Description

Technical Field

[0001] This utility model relates to the technical field of surface treatment, and in particular to an impact jet device for surface treatment of copper and aluminum bimetals. Background Technology

[0002] Impact jet technology is an effective method for preparing copper-aluminum bimetallic composite materials. It can make full use of the heat and momentum of molten aluminum to achieve a good bond between copper and aluminum. By using impact jet technology, molten aluminum is poured onto a copper substrate. The heat of the molten aluminum is used to heat the surface of the copper substrate to a molten state. Then, the momentum of the impact jet is used to break up the oxide film on the surface of the copper substrate, thereby eliminating the obstacle of the oxide film to copper-aluminum composite and achieving a good copper-aluminum bond.

[0003] In current jet impact devices, the movement of the aluminum silicate tank is generally controlled by a belt. Belts occupy a lot of space, are prone to interfering with the recovery of aluminum liquid, and often encounter many problems in conveying, affecting normal operation. At the same time, the overflow baffle is not easy to control during opening and closing. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] like Figure 1 As shown, an impact jet device for copper-aluminum bimetallic surface treatment includes two supports 1, a lead screw 2, a drive motor 3, an aluminum silicate tank 4, an aluminum silicate felt 5, an internal tank 6, a telescopic cylinder 7, an aluminum silicate overflow baffle 8, an aluminum liquid recovery tank 9, a molten aluminum liquid storage tank 10, a jet port 11, a limiting rod 12, a U-shaped filter screen 13, a support plate 14, and a mounting plate 15.

[0021] A lead screw 2 is installed between two supports 1. The lead screw 2 is connected to a drive motor 3. A lead screw nut is threaded onto the lead screw 2, and an aluminum silicate tank 4 is fixed to the front side of the lead screw nut. The aluminum silicate tank 4 has an L-shaped longitudinal section and closed side plates on both the front and rear sides. Aluminum silicate felt 5 is laid on the inner wall and bottom plate of the aluminum silicate tank 4. An internal groove 6 is opened on the bottom plate of the aluminum silicate tank 4. A telescopic cylinder 7 is installed in the internal groove 6. An aluminum silicate overflow baffle 8 is connected to the piston rod end of the telescopic cylinder 7. The top height of the aluminum silicate overflow baffle 8 is lower than the height of the side plate of the aluminum silicate tank 4. The aluminum silicate overflow baffle 8 is fitted to one side of the opening of the aluminum silicate tank 4. Several aluminum liquid recovery tanks 9 are provided below one side of the opening of the aluminum silicate tank 4. A molten aluminum liquid storage tank 10 is provided above the aluminum silicate tank 4. A jet port 11 is provided at the bottom of the molten aluminum liquid storage tank 10.

[0022] The aluminum silicate overflow baffle 8 includes a support baffle 801, an adjusting baffle 802, an upper cover baffle 803, a first insertion block 804, a second insertion block 805, and a pressure plate 806.

[0023] The support baffle 801 is fixed to the piston rod end of the telescopic cylinder 7. Several intermediate adjustment baffles 802 are installed on the top of the support baffle 801, and the top cover baffle 803 is installed on the top of the uppermost intermediate adjustment baffle 802.

[0024] The support baffle 801 has a first insertion slot at the top, the adjustment baffle 802 has a first insertion block 804 at the bottom and a second insertion slot at the top, and the upper cover baffle 803 has a second insertion block 805 at the bottom. The first insertion block 804 is inserted into the corresponding first insertion slot or second insertion slot, and the second insertion block 805 is inserted into the corresponding second insertion slot.

[0025] A pressure plate 806 is provided on the side wall of the support baffle 801, and the pressure plate 806 is set on the upper surface of the aluminum silicate felt 5.

[0026] A limiting rod 12 is provided between the two supports 1, and the nut seat is movably inserted through the limiting rod 12.

[0027] A U-shaped filter screen 13 is installed inside the molten aluminum storage tank 10, which can filter the molten aluminum in the molten aluminum storage tank 10. Impurities on both sides of the U-shaped structure can slide down under the action of gravity, reducing the probability of blockage on both sides and reducing the frequency of cleaning.

[0028] A support plate 14 is provided on the inner wall of the molten aluminum storage tank 10, and mounting plates 15 are provided on both sides of the top of the U-shaped filter screen 13. The mounting plates 15 and the support plate 14 are fixedly connected by bolts.

[0029] In this invention, molten aluminum flows down from the molten aluminum storage tank 10 through the jet port 11, coating the copper substrate 16 with molten aluminum. The heat of the coating aluminum heats the surface of the copper substrate 16 to a molten state. Then, the momentum of the impact jet breaks the oxide film on the surface of the copper substrate 16, thereby eliminating the obstruction of the oxide film to the copper-aluminum composite and achieving a good copper-aluminum bond. During the process, the lead screw 2 drives the aluminum silicate tank 4 to move. The recovered molten aluminum flows out from the aluminum silicate overflow baffle 8 and is distributed into different molten aluminum recovery tanks 9. The molten aluminum that cannot be discharged can be discharged after the aluminum silicate overflow baffle 8 is opened.

[0030] The aluminum silicate overflow baffle 8 is adjustable, and its height can be changed as needed to control the contact time between the molten aluminum and the copper substrate 16.

[0031] The lead screw 2 of this invention controls movement more smoothly, without interference, resulting in better control. The opening and closing of the aluminum silicate overflow baffle 8 is also more flexible and convenient.

[0032] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
