Description

Technical Field

[0001] This invention belongs to the field of copper alloy manufacturing technology, specifically relating to a novel copper alloy melting and casting device. Background Technology

[0002] In recent years, with the continuous development of industrial technology, copper alloys have been widely used in machinery, electronics, construction, transportation and other fields due to their excellent mechanical properties, good electrical and thermal conductivity, and corrosion resistance. To improve the production efficiency and quality of copper alloy castings, researchers have developed a new type of copper alloy melting and casting device.

[0003] A Chinese patent (publication number CN221464308U) discloses a casting apparatus for processing copper alloy bars, comprising a shell, an inner furnace body, and a top cover. The top of the shell is equipped with a placement mechanism, which includes two fixed rods movably mounted on the outer wall of the top of the shell. Multiple baffles are fixedly installed between the two fixed rods, and two connecting rods are fixedly installed between the two fixed rods. A locking rod is fixedly installed on the bottom outer wall of each connecting rod. In this casting apparatus for processing copper alloy bars, after the multiple baffles are placed inside the inner furnace body, a groove adapted to the diameter of the copper alloy bar is formed between the baffles.

[0004] Existing new copper alloy melting and casting equipment requires the periodic discharge of molten material from the melting furnace during the melting and casting process. Existing melting furnaces guide the molten material by setting up a discharge structure. However, after the material is discharged, a lot of material is easily left on the discharge structure, and after a period of time, the material cools and solidifies in the discharge structure, which makes subsequent cleaning work inconvenient.

[0005] To address the above problems, we propose a novel copper alloy melting and casting device. Utility Model Content

[0006] The purpose of this invention is to provide a novel copper alloy melting and casting device that can solve the problem in the prior art where a large amount of material remains in the discharge trough of the melting furnace, and after a period of time, the material cools and solidifies in the discharge trough, causing inconvenience to subsequent cleaning work.

[0007] The specific technical solution adopted in this utility model is as follows:

[0008] A novel copper alloy melting and casting device includes a cylinder with two symmetrical support legs fixedly installed at the bottom. The cylinder has an annular cavity with multiple heating bars inside. The heating bars are fixed inside the cylinder, and the cylinder has multiple inlet holes for the heating bars to enter.

[0009] The bottom end of the cylinder is connected to and fixed with a vertical pipe, and a horizontal pipe is integrally formed on the vertical pipe. An electric telescopic rod is fixedly installed at the bottom of the cylinder, and a sealing plug is fixed at the output end of the electric telescopic rod. The sealing plug can be inserted into the horizontal pipe and seal the vertical pipe and the horizontal pipe. A support plate is fixedly installed at the bottom of the cylinder, and an annular ring is rotatably installed on the support plate. Multiple scrapers arranged in a circular array are fixed inside the annular ring.

[0010] The present invention is further configured such that: the support plate is provided with a driving mechanism, the driving mechanism is connected to the annular ring and is used to drive multiple scrapers to rotate outside the sealing plug.

[0011] The present invention is further configured such that: a sealing cap is provided at the upper port of the cylinder, and the lower end of the sealing cap is inserted into the upper port of the cylinder and is used to seal the upper port of the cylinder.

[0012] The present invention is further configured such that: the driving mechanism includes a gear ring, the gear ring is sleeved outside the annular ring and fixedly connected to the annular ring.

[0013] The present invention is further configured such that: the driving mechanism further includes a servo motor, the servo motor is fixedly mounted on the support plate, and a drive wheel is fixedly mounted on the output shaft end of the servo motor, the drive wheel meshing with the gear ring.

[0014] The present invention is further configured such that: the servo motor is provided with a protective cover, and the cylinder is wrapped with an insulation sleeve.

[0015] The technical effects achieved by this utility model are as follows:

[0016] This utility model discloses a novel copper alloy melting and casting device. An electric telescopic rod moves a sealing plug into multiple annular rings. A servo motor drives a drive wheel to rotate, causing a scraper to rotate and scrape away residual material from the sealing plug's surface. After discharging the material, the device cleans the surface of the sealing plug, preventing excessive material residue from solidifying upon cooling and facilitating subsequent cleaning.

[0022] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1-4 As shown, a novel copper alloy casting device includes a cylinder 1, with two symmetrical support legs 2 fixedly installed at the bottom of the cylinder 1. An annular cavity 3 is provided inside the cylinder 1, and multiple heating bars 4 are provided inside the annular cavity 3. The heating bars 4 are fixed inside the cylinder 1, and multiple inlet holes for the heating bars 4 are opened on the cylinder 1.

[0024] A vertical pipe 6 is connected to and fixed at the bottom of the cylinder 1. A horizontal pipe 7 is integrally formed on the vertical pipe 6. An electric telescopic rod 8 is fixedly installed at the bottom of the cylinder 1. A sealing plug 9 is fixed at the output end of the electric telescopic rod 8. The sealing plug 9 can be inserted into the horizontal pipe 7 and seal the vertical pipe 6 and the horizontal pipe 7. A support plate 10 is fixedly installed at the bottom of the cylinder 1. An annular ring 11 is rotatably installed on the support plate 10. Multiple scraper blades 12 arranged in a circular array are fixed inside the annular ring 11. A driving mechanism is provided on the support plate 10. The driving mechanism is connected to the annular ring 11 and is used to drive the multiple scraper blades 12 to rotate outside the sealing plug 9.

[0025] The cylinder 1 has a sealing cap 5 at its upper port, the lower end of which is inserted into the upper port of the cylinder 1 to seal it. The drive mechanism includes a gear ring 13, which is fitted over and fixedly connected to an annular ring 11. The drive mechanism also includes a servo motor 14, which is fixedly mounted on a support plate 10. A drive wheel 15 is fixedly mounted on the output shaft of the servo motor 14, and the drive wheel 15 meshes with the gear ring 13. The cylinder 1 is made of a heat-conducting metal.

[0026] When the heating bar 4 is working, heat can be conducted to the copper alloy inside the cylinder 1, thereby heating the copper alloy to a molten state. During heating, the sealing plug 9 seals the vertical pipe 6 and the horizontal pipe 7. During discharge, the electric telescopic rod 8 moves the sealing plug 9 outside the horizontal pipe 7, and the vertical pipe 6 is opened, allowing the molten material inside the cylinder 1 to be discharged through the vertical pipe 6, thus performing the discharge operation. The electric telescopic rod 8 moves the sealing plug 9 into multiple annular rings 11, and the servo motor 14 drives the drive wheel 15 to rotate, causing the scraper 12 to rotate and scrape off the material remaining on the surface of the sealing plug 9. After the discharge is completed, the electric telescopic rod 8 moves the sealing plug 9 into the horizontal pipe 7, and the sealing plug 9 seals the vertical pipe 6 and the horizontal pipe 7.

[0027] After the material is discharged, the device cleans the material remaining on the surface of the sealing plug 9 to prevent the material from easily remaining on the sealing plug 9 and solidifying upon cooling, thus facilitating the subsequent cleaning of the sealing plug 9.

[0028] The servo motor 14 is equipped with a protective cover. The cylinder 1 is wrapped with an insulation sleeve. Multiple connecting blocks 17 are fixedly installed inside the cylinder 1, and each connecting block 17 has a limiting sleeve 16 fixedly installed at its end. By inserting the lower end of the columnar copper alloy into the limiting sleeve 16, the columnar copper alloy can be evenly distributed inside the cylinder 1, avoiding the problem of uneven heating caused by multiple columnar copper alloys being stacked. The melting points of the cylinder 1, vertical pipe 6, horizontal pipe 7, limiting sleeve 16, and connecting blocks 17 are all higher than the melting point of copper alloy.

[0029] The working principle of this utility model is as follows: The heating bar 4 is controlled to conduct heat to the copper alloy inside the cylinder 1, heating the copper alloy to a molten state. During heating, the sealing plug 9 seals the vertical pipe 6 and the horizontal pipe 7. During discharge, the electric telescopic rod 8 moves the sealing plug 9 outside the horizontal pipe 7, and the vertical pipe 6 is opened, allowing the molten material inside the cylinder 1 to be discharged through the vertical pipe 6. The electric telescopic rod 8 moves the sealing plug 9 into multiple annular rings 11, and the servo motor 14 drives the drive wheel 15 to rotate, causing the scraper 12 to rotate and scrape off any remaining material on the surface of the sealing plug 9. After discharge is complete, the electric telescopic rod 8 moves the sealing plug 9 into the horizontal pipe 7, sealing both the vertical pipe 6 and the horizontal pipe 7.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
