[0002] A copper alloy continuous casting machine is a casting device that rapidly cools and solidifies liquid copper alloy through a crystallizer and achieves continuous metal forming with the help of a traction device, through the directional solidification and dynamic forming of liquid metal.

[0003] Currently, in the application of copper alloy continuous casting machines, it is necessary to use a shearing structure to cut the copper alloy strip to a fixed length so that it can be processed in the future.

[0004] However, in traditional copper alloy continuous casting machines, due to the lack of convenient strip positioning measures before the shearing operation, the copper alloy strip is prone to shaking during the contact between the cutter and the copper alloy strip, which in turn affects the shearing effect of the copper alloy strip.

[0005] To address this problem, the present invention provides a horizontal continuous casting machine for copper alloys with shearing assistance function. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1:

[0032] Please see Figure 1-5 A horizontal continuous casting machine for copper alloys with shearing assistance function, comprising:

[0033] Winding machine body 1, the winding machine body 1 is used to wind copper alloy strip;

[0034] Two guide rollers 2 are provided, and a shearing frame 3, a puller 10 and a secondary cooler 11 are provided between the two guide rollers 2. The puller 10 is located between the shearing frame 3 and the secondary cooler 11. The puller 10 is used to transfer the copper alloy strip between the shearing frame 3 and the secondary cooler 11.

[0035] Carrier plate 4 is fixedly connected to the middle of the shearing frame 3. A hydraulic cylinder 5 is fixedly connected to the top of the shearing frame 3. A push plate 6 is fixedly connected to the output end of the hydraulic cylinder 5. A shearing blade 7 is fixedly connected to the bottom end of the push plate 6. A transmission rack 8 is fixedly connected to both ends of the push plate 6. A stabilizing component 9 is provided at both ends of the shearing frame 3. The stabilizing component 9 is used to cooperate with the transmission rack 8 to position the copper alloy strip.

[0036] The main body of the smelting furnace 13 is used to melt copper alloy billets. A holding furnace 12 is provided between the main body of the smelting furnace 13 and the secondary cooler 11. The holding furnace 12 is used to maintain the surface temperature of the copper alloy.

[0037] In this embodiment, the main body 1 of the coiler is a coreless coiler. The forward and backward movement of the main body 1 on the casting line is provided by a hydraulic cylinder with an 800mm stroke. It is equipped with a set of feeding devices. The main body has a clamping roller system, an adjustable bending roller system, and a fixed drive roller system. The stroke of the clamping roller and the bending roller is adjusted according to the thickness of the incoming material. After the billet enters the coiler, the clamping roller receives the billet entry signal, the clamping roller clamps the billet, and the billet pushes the coiler body until it is furthest away from the puller 10. At this time, the sensor signal is issued, the fixed roller rotates, and the coiling begins. The speed is selected to be higher than the average speed of the puller and moves towards the puller 10. In this way, the coiler coils the copper billet into a coil. When the coiler returns to the original position, the coiling stops, and the main body 1 of the coiler moves backward with the puller plate until it moves to the furthest away from the puller 10. This process is repeated continuously until the copper strip reaches the required coiling length. This is a mature existing technology and will not be described in detail here.

[0038] In this embodiment, a capacitor cabinet 24, a control cabinet 25, and a reactor 26 that cooperate with the main body 13 of the smelting furnace are also included. The main body 13 of the smelting furnace is equipped with a crystallizer. The crystallizer adopts a plate or hole type multi-way cooling circuit, and the outlet water is equipped with temperature monitoring. It is also equipped with a four-piece graphite, which is easy to repair and reuse. In order to ensure the quality of the billet, the graphite is used for a certain period of time, which depends on the operation mode, the casting material, the gas content, and the casting temperature of the material. This is a mature existing technology and will not be described in detail here.

[0039] In this embodiment, two extension plates are fixedly connected to the middle of both sides of the shearing frame 3. Multiple support rollers are provided between the two extension plates at the same end. By supporting the support rollers through the extension plates, the copper alloy strip can be effectively guided to ensure the subsequent shearing effect of the copper alloy strip.

[0040] In this embodiment, a linear guide rod is vertically slidably connected to the top of the shearing frame 3, and the bottom end of the linear guide rod is fixedly connected to the push plate 6. The linear guide rod can stably guide the vertical displacement of the push plate 6. A limit piece is also fixedly connected to the top of the linear guide rod. The limit piece can limit the stroke of the linear guide rod and prevent the linear guide rod from detaching from the shearing frame 3.

[0041] In this embodiment, the main body 12 of the heat-insulating furnace is a vertical furnace structure, lined with insulating bricks and high-alumina castable. The upper and lower furnace bodies are detachable for easy furnace construction. The lower furnace body is lined with insulating material and high-grade composite binder, and is equipped with a temperature measuring thermocouple with continuous temperature measurement, display, and over-temperature alarm functions. Its service life is basically the same as that of the furnace body. The temperature measuring point has a unique structural design that is easy to replace and is a mature existing technology, which will not be described in detail here.

[0042] In summary, the raw materials are first prepared according to the process requirements, with approximately one ton of dried raw materials per box. Based on the production product and the feeding process, these materials are then added in an orderly manner to the smelting furnace containing molten copper. The power of the smelting furnace body 13 is supplied by a 10kV three-phase adjustable transformer, offering eighteen voltage settings. The low-voltage setting is used for furnace heating, and the high-voltage setting is used for copper melting. It is equipped with a three-phase balancing device and a complete protection and alarm system, which can be adjusted according to the eighteen different power settings. This allows for convenient sampling and testing after the molten copper reaches the target temperature. After passing the test, the furnace awaits conversion. During production, covering materials and additives need to be added to the smelting furnace.

[0043] The raw materials processed by the smelting furnace body 13 are directly transferred to the holding furnace body 12. The power of the holding furnace body 12 is provided by the voltage of a three-phase stepped voltage regulating transformer (400V input line). It is equipped with a three-phase balancing device and a complete protection and alarm system. The system control is implemented by PLC, with manual control and automatic control. Manual control is generally used for heating, and automatic control is used for normal production. There is a pre-built temperature measuring device (thermocouple is detachable) in the furnace lining of the upper furnace body to indirectly measure the temperature of the molten copper. The power is adjusted manually or automatically according to the furnace temperature to meet the production requirements.

[0044] Example 2:

[0045] Please see Figure 1-5 This embodiment provides a technical solution based on Embodiment 1: the stabilization component 9 includes:

[0046] Linkage shaft 14 is rotatably connected to the middle of shear frame 3. An eccentric plate 15 is fixedly connected to one end of linkage shaft 14 outside shear frame 3. A linkage rod 16 is rotatably connected to the other end of eccentric plate 15 away from linkage shaft 14.

[0047] The guide plate 17 has a positioning plate 18 fixedly connected to both ends. Both ends of the shearing frame 3 are provided with clearance grooves. The positioning plate 18 is vertically slidably connected inside the corresponding clearance groove. The end of the linkage rod 16 away from the eccentric plate 15 is also rotatably connected to the middle of the guide plate 17.

[0048] An extension seat 19 is fixedly connected to the inner side of the shear frame 3. A central shaft 20 is rotatably connected to one end of the extension seat 19. A drive spur gear 21 and a transmission worm gear 22 are fixedly connected to the central shaft 20. The drive spur gear 21 meshes with the transmission rack 8. A drive worm wheel 23 is fixedly connected to one end of the linkage shaft 14 near the transmission worm gear 22. The drive worm wheel 23 meshes with the transmission worm gear 22.

[0049] In this embodiment, support holes are provided in the middle of both ends of the shearing frame 3, and the linkage shaft 14 is connected to the inside of the support holes by ball bearings. The support holes enable stable assembly of the linkage shaft 14, and the ball bearings improve the smoothness of the rotation of the linkage shaft 14.

[0050] In this embodiment, an assembly seat is provided in the middle of the top of the guide plate 17, and the end of the linkage rod 16 away from the eccentric plate 15 is connected to the assembly seat through a rotating shaft. With the setting of the assembly seat, the linkage rod 16 can be effectively assembled by means of the rotating shaft, ensuring the stability of the linkage rod 16 in linkage between the guide plate 17 and the eccentric plate 15.

[0051] In this embodiment, anti-slip plates are fixedly connected to both ends of the bottom of the positioning plate 18, and anti-slip textures are provided at the bottom of the anti-slip plates. By setting the anti-slip plates with anti-slip textures, the friction between the positioning plate 18 and the copper alloy strip can be increased, and the loosening of the copper alloy product during shearing can be avoided.

[0052] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0053] Working principle: The copper alloy strip after being processed by the main body 13 of the smelting furnace is introduced into the main body 12 of the holding furnace, and the copper alloy strip is kept warm by the main body 12 of the holding furnace. Subsequently, the copper alloy strip is cooled by the secondary cooler 11, and the copper alloy strip is transferred between the secondary cooler 11 and the shearing frame 3 by the drawing machine 10. Then, with the auxiliary support of the guide roller 2, the copper alloy strip is wound up by the coiler main body 1.

[0054] When it is necessary to shear the copper alloy strip, the hydraulic cylinder 5 is first activated to push the push plate 6 to move downward continuously. As the push plate 6 moves downward continuously, the transmission rack 8 will mesh with the matching spur gear 21, thereby driving the transmission worm gear 22 to rotate through the central shaft 20. This causes the transmission worm gear 22 to connect to the matching worm wheel 23, which in turn drives the eccentric plate 15 to rotate through the linkage shaft 14. Since the linkage rod 16 is connected between the eccentric plate 15 and the guide plate 17, when the eccentric plate 15 rotates, the positioning plate 18 is pushed to move vertically through the linkage rod 16 to cooperate with the carrier plate 4 to position the copper alloy strip between the positioning plate 18 and the carrier plate 4. When the transmission rack 8 disengages from the matching spur gear 21, the linkage shaft 14 will stop rotating, so it will not interfere with the operation of the shearing blade 7. When the shearing blade 7 contacts the copper alloy strip, it can be sheared.
