Description

Technical Field

[0001] This utility model relates to the field of copper strip preparation technology, specifically to a shrinkage-prevention casting device for preparing copper strip. Background Technology

[0002] The casting equipment for preparing copper strips forms the strips through continuous horizontal casting, allowing them to directly enter the subsequent rolling process, reducing intermediate steps. It is often combined with continuous rolling technology, using high-processing rolling to fully break up the as-cast structure, and annealing to eliminate internal stress, ultimately obtaining a product with moderate hardness.

[0003] In existing copper strip casting equipment, the casting machine is placed horizontally, and the molten copper remains stationary after entering the intermediate tank. This results in low static pressure in the molten copper, leading to insufficient feeding of the molten copper during the subsequent cooling of the copper billet in the crystallizer. Consequently, shrinkage cavities easily appear in the center of the billet. Furthermore, the copper billet shrinks to some extent upon cooling, resulting in a slightly smaller size than the predetermined dimensions. This leads to insufficient processing accuracy of the copper strip and affects the processing efficiency of the casting equipment. Optimization and improvement are necessary. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When filling the molten copper, this utility model uses a filter screen made of high-temperature resistant copper alloy to pre-treat the molten copper, which disperses large air bubbles in the molten copper and facilitates their floating. Then, in conjunction with the impact of the gear disc on the convex strip, the transfer box vibrates, further expelling air bubbles.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] like Figure 1 - Figure 4 As shown, this application provides a casting equipment for preventing shrinkage cavities in the preparation of copper strips, including: a support plate 1, a billet guide groove 2 fixedly connected to the top center of the support plate 1, and a transfer box 11 connected to one side of the billet guide groove 2. A packing hopper 3 is fixedly connected to the top of the transfer box 11, and the molten copper flows along the packing hopper 3 through the transfer box 11 into the interior of the billet guide groove 2; specifically, as shown... Figure 1 As shown, an adjustment frame 4 is fixedly connected to one end of the top of the support plate 1. A slider 5 is slidably connected to the top of the adjustment frame 4. A copper container 6 is fixedly connected to the top of the slider 5. The copper container 6 can be slidably adjusted at the top of the adjustment frame 4 through the connection of the slider 5, so as to facilitate the uniform filling of copper liquid.

[0019] Specifically, such as Figure 1 As shown, a cooler 22 is fixedly connected to the middle of the outer side of the billet guide groove 2. The cooler 22 is used to cool the copper liquid to make it reach a suitable state for billet pulling. A billet pulling machine 23 is fixedly connected to one end of the outer side of the billet guide groove 2. The billet pulling machine 23 pulls and shapes the copper liquid after temperature control. An output roller group 24 is fixedly connected to one end of the billet pulling machine 23. The output roller group 24 guides and transmits the product after billet pulling.

[0020] The vibration exhaust assembly includes a rib 13 and a retaining frame 7. The rib 13 is connected to the outside of the transfer box 11, and a gear disk 15 is provided on the outside of the rib 13. The retaining frame 7 is connected to the top of the packing hopper 3, and a filter screen 9 is fixedly connected to the inside of the retaining frame 7. The vibration exhaust assembly is used for vibration exhaust before copper casting; specifically, as shown... Figure 2 As shown, pins 8 are fixedly installed at the four corners of the bottom of the card frame 7. The pins 8 are inserted into the pre-set holes inside the top wall of the filling hopper 3. Handles 10 are fixedly connected to both ends of the outer side of the card frame 7. The handles 10 facilitate the removal of the card frame 7.

[0021] Specifically, such as Figure 3As shown, the inner side of the transfer box 11 is provided with an inclined groove 12, and the transfer box 11 is fixedly connected to the billet guide groove 2. The inclined groove 12 can facilitate the control of the flow direction of the copper liquid.

[0022] Specifically, such as Figure 3 As shown, a motor 14 is fixedly connected to the inner bottom of the adjustment frame 4, and a gear disk 15 is fixedly connected to the inner rotating end of the motor 14. The gear disk 15 is attached to the outer side of the convex strip 13, which is made of rubber. When the gear disk 15 collides with the convex strip 13, it can deform. Intermittent collisions can drive the transfer box 11 to vibrate, promoting the upward discharge of gas during copper liquid filling.

[0023] The pretreatment adjustment assembly includes a connecting frame 16, which is fixedly installed on one side of the top of the support plate 1. A push plate 18 is connected to the inner side of the connecting frame 16, and a pressure control plate 20 is fixedly connected to the bottom end of the push plate 18. The pretreatment adjustment assembly is used for pretreatment before casting billet pulling.

[0024] Specifically, such as Figure 4 As shown, a telescopic cylinder 17 is fixedly installed on the inner top of the connecting frame 16, and a push plate 18 is connected to the bottom of the telescopic cylinder 17. Guide rods 19 are fixedly connected to both sides of the top of the push plate 18. The guide rods 19 are provided to improve the stability of the telescopic cylinder 17 in controlling the adjustment of the push plate 18.

[0025] Specifically, such as Figure 4 As shown, a temperature control block 21 is fixedly connected to the inner side of the pressure control plate 20. The temperature control block 21 can control the temperature of the transmitted copper liquid to ensure the solidification of the casting and effectively reduce the generation of shrinkage cavities.

[0026] In this embodiment: when filling the copper liquid, a filter screen 9 made of high-temperature resistant copper alloy is used to pre-treat the copper liquid to disperse large air bubbles in the copper liquid, which is conducive to floating. Then, in conjunction with the impact of the gear disk 15 on the convex strip 13, the transfer box 11 vibrates to further expel air bubbles and reduce the deformation generated after the copper liquid cools. Before cooling the copper liquid, a liftable push plate 18 is set to drive the pressure control plate 20 to squeeze the copper liquid for pre-treatment squeezing before blanking. The squeezing also increases the tension of the copper liquid, which is easier to adapt to the deformation generated during subsequent blanking.

[0027] Specifically, during the preparation and casting of the copper strip, the molten copper is first poured into the copper container 6. The copper container 6 can then be adjusted by sliding at the top of the adjusting frame 4 to ensure a more uniform pouring of the molten copper onto the top of the filter screen 9 inside the packing hopper 3. The filter screen 9 is V-shaped to increase the filtration area, remove impurities from the molten copper, disperse large air bubbles, and improve the fluidity of the molten copper. The molten copper is then guided through the transfer box 11 into the billet guide groove 2. Outside the transfer box 11, a motor 14 drives a gear disk 1. 5. The orderly impact convex strips 13 cause the transfer box 11 to vibrate at the same frequency, which facilitates the discharge of air bubbles. Then, the copper liquid flows through the billet guide groove 2 to the cooler 22. During the flow, the telescopic cylinder 17 drives the push plate 18 and the pressure control plate 20 to press, so that the copper strip can be pre-treated by pressing. The inner temperature control block 21 can adjust the transmission temperature of the copper liquid to improve the fluidity of the copper liquid. Then, the cooler 22 cools it to a suitable state, and then the billet is drawn and shaped by the billet drawing machine 23. Finally, it is output through the guide of the output roller group 24.
