Description

Technical Field

[0001] The utility model relates to the technical field of metal processing and manufacturing equipment, in particular to a novel heating system for nonferrous metal bar blanks. Background Art

[0002] Non-ferrous metal bar billets usually refer to long unprocessed products made of non-ferrous metals such as copper, aluminum, lead, zinc, and nickel. These metal bar billets are usually used to manufacture wires, cables, pipes, mechanical parts, auto parts, building materials, etc. The specifications and sizes of non-ferrous metal bar billets can be customized according to customer requirements. They usually have good thermal conductivity, electrical conductivity and corrosion resistance. Non-ferrous metals are usually extruded, which generally involves multiple processes such as ingot splitting, transfer, heating, and extrusion. The traditional practice is to saw the long bars produced in the melting and casting workshop in the sawing workshop and stack them in the material frame, and then transport them to the extrusion workshop by forklift for heating and extrusion.

[0003] Existing heating devices usually have a feeding mechanism for feeding the heating device, thereby avoiding the inconvenience caused by manual feeding and improving the heating efficiency. For example, Chinese patent announcement No. CN202297722U discloses "a heating device for metal bars", which has a small size. The inner diameter of the furnace tube of the horizontal step-type medium-frequency induction heating furnace is only for a single metal bar to pass through, and the length of the furnace tube is only about 3 meters. It is convenient to compactly configure it next to the lower production line, and the radiation heat loss is small, which will not affect the electrical equipment of the lower production line and hinder the operation of the workers on the lower production line. Because it can be compactly configured next to the lower production line, the overall footprint of the lower production line and the heating furnace is reduced;

[0004] However, in actual use, the specifications of the bars are different, and the bars need to be cut after or before processing. During cutting, larger waste chips are collected and recycled, but smaller metal particles will scatter, which not only pollutes the processing environment, but also causes a waste of resources. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art that small metal particles will scatter and splash when the bars are cut, which not only pollutes the processing environment but also causes waste of resources, and proposes a new type of non-ferrous metal bar blank heating system.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The dust removal system includes a cyclone dust removal device, a power distribution cabinet and an operating table, and the power distribution cabinet is electrically connected to the operating table.

[0009] Furthermore, the heating device includes a preheating device and a main heating device, the preheating device is a gas furnace, and the main heating device is an induction furnace.

[0010] Furthermore, a water cooling system is provided on one side of the heating device, and the water cooling system is connected to the pre-heating device and the main heating device.

[0011] Furthermore, the feeding end of the cyclone dust removal device is provided with an air suction structure, and the air suction structure is arranged near the cutting device.

[0012] Furthermore, a screw is arranged inside the briquetting machine, a first motor is arranged on the briquetting machine, an output shaft of the first motor is fixedly connected to the screw, a threaded sleeve is sleeved on the outside of the screw, and a pressing portion is fixedly arranged on the lower end of the threaded sleeve.

[0015] The utility model proposes a novel non-ferrous metal billet heating system, which has the following beneficial effects:

[0016] In the utility model, the production cost can be effectively reduced by using the gas furnace and the induction furnace together, which is more suitable for use in areas with limited power supply. The heating device is fed with materials through the feeding assembly, and since the heating system is provided with a cutting device, the bar blanks of different specifications can be cut into the bar blanks of the required length, so that the heated bar blanks can be collected for further processing, thereby avoiding the various types of material frames for loading the bar blanks due to the different specifications of the bar blanks during transportation, which are difficult to manage, and a large number of material frames that do not meet the requirements of the current production line are idle, which increases the cost;

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4A novel heating system for nonferrous metal billets comprises a heating device 1 and a cutting device 2. A storage bin 3 is arranged on one side of the heating device 1. The storage bin 3 is provided with a buffer, a translation, and a lifting device. The long bars are transported smoothly without impact, and the noise is greatly reduced compared with the traditional rolling conveying. A feeding assembly 4 is arranged between the storage bin 3 and the heating device 1. A cutting device 5 is arranged on one side of the heating device 1. A sizing machine 6 is arranged on one side of the cutting device 5. A conveying mechanism 7 is arranged on one side of the sizing machine 6. A dust removal system 8 is arranged on one side of the cutting device 5. The output end of the dust removal system 8 is connected to a briquetting machine 9.

[0025] The dust removal system 8 includes a cyclone dust removal device 81, a power distribution cabinet 82 and an operating table 83. The power distribution cabinet 82 is electrically connected to the operating table 83, and the operating table 83 is electrically connected to the above devices.

[0026] In the utility model, the heating device 1 is fed by the feeding assembly 4, and since a cutting device 5 is provided in this embodiment, rod blanks of different specifications can be cut into rod blanks of required length, so that the heated rod blanks can be collected for further processing, thereby avoiding the problem of different specifications of rod blanks during transportation, resulting in a wide variety of material frames for loading rod blanks, which are difficult to manage, and a large number of material frames that do not meet the requirements of the current production line are idle, thereby increasing costs.

[0027] The dust removal system 8 collects the smaller debris during cutting, and inputs the debris into the briquetting machine 9 along the output end, where the debris is squeezed into blocks to form debris briquettes for easy recycling. The overall layout of this system is compact, the process flow is smooth, construction costs and management costs are saved, and economic benefits are improved.

[0028] Furthermore, in this embodiment, the heating device 1 includes a preheating device 11 and a main heating device 12. The preheating device 11 is a gas furnace, and the main heating device 12 is an induction furnace. The gas furnace can be used to evenly heat the rod material, which is suitable for areas where fuel is easily available and can effectively reduce production costs. The induction furnace can be used to gradient heat the rod material, and isothermal extrusion can be achieved in the subsequent extrusion process, which greatly improves the extrusion quality. At the same time, due to the influence of international energy-saving and emission reduction policies, the declaration and use of high-power transformers are restricted. The use of induction heating alone consumes a lot of electricity, which is not conducive to promotion and use in areas with limited power supply.

[0029] Furthermore, in this embodiment, a water cooling system 13 is provided on one side of the heating device 1, and the water cooling system 13 is connected to the pre-heating device 11 and the main heating device 12. By providing the water cooling system 13, the circuit parts of the pre-heating device 11 and the main heating device 12 are protected to prevent the circuit from being affected by excessive temperature.

[0030] It should be noted that, in this embodiment, an air suction structure 811 is provided at the feed end of the cyclone dust collector 81. The air suction structure 811 is arranged near the cutting device 5. The air near the cutting device 5 is sucked through the air suction structure 811, so that the splashed small-volume debris is sucked into the cyclone dust collector 81 for filtration, and the small-volume debris is filtered out for collection.

[0031] In addition, in the present embodiment, a screw 91 is provided in the briquetting machine 9, a first motor 92 is provided on the briquetting machine 9, an output shaft of the first motor 92 is fixedly connected to the screw 91, a threaded sleeve 93 is provided on the outside of the screw 91, a pressing portion 94 is fixedly provided at the lower end of the threaded sleeve 93, a telescopic rod is provided between the upper end of the pressing portion 94 and the top of the briquetting machine 9, the screw 91 is driven by the first motor 92 to rotate and control the threaded sleeve 93 and the pressing portion 94 to move downward to briquette the debris. In some embodiments, a hydraulic rod is provided on one side of the briquetting machine 9, and the output shaft of the hydraulic rod is connected to a push plate, which can push the debris to the bottom of the pressing portion 94, thereby facilitating the pressing portion 94 to briquette the debris.

[0032] In detail, in the present embodiment, a discharge port is provided at the bottom of the briquetting machine 9, and a movable door 95 is rotatably connected to the discharge port through a hinge, a protrusion 96 is fixedly provided at the lower end of the movable door 95, and accommodating grooves 97 are provided on both sides of the discharge port, and limiting parts 971 are slidably provided in the accommodating grooves 97, and a double-headed screw 972 threadedly connected to the two limiting parts 971 is rotatably provided in the discharge port, and a second motor 973 powered by the double-headed screw 972 is fixedly provided on one side of the briquetting machine 9, and the movable door 95 is restricted by the limiting part 971 to prevent the movable door 95 from being opened by force during briquetting, and the second motor 973 is provided to drive the double-headed screw 972 to rotate and control the movement of the two limiting parts 971. When the movable door 95 needs to be opened, the two limiting parts 971 are moved into the accommodating groove 97 to open the movable door 95 and take out the crushed briquette.

[0033] In more detail, in some embodiments, a guide groove is provided at the bottom of the limiting portion 971, and a guide rail 98 matching the guide groove is fixedly provided in the discharge port. The guide rail 98 is provided to limit the limiting portion 971 to prevent it from being deformed and misaligned with the accommodating groove 97.

[0034] Working mode: When working, a gas furnace can be used to heat the bar material at a uniform temperature, which is suitable for areas where fuel is easily available and can effectively reduce production costs. An induction furnace can be used to heat the bar material in a gradient manner, and isothermal extrusion can be achieved in the subsequent extrusion process, greatly improving the extrusion quality. A water cooling system 13 is provided to protect the circuit part of the preheating device 11 and the main heating device 12, and the heat generated by the coil during the heating process of the induction furnace is taken away by the water cooling system 13 to control the coil temperature to protect the coil insulation. The cutting device 5 can cut the bar blanks of different specifications into the required length of the bar blanks, and the length setting machine 6 can control the position of the long bar material so that the cutting device 5 can cut the short bar of precise length. The short bar blanks can be uniformly transported by the material transfer vehicle, which reduces the difficulty of transportation, avoids a wide variety of material frames, and avoids the difficulty of management. At the same time, it avoids a large number of material frames that do not meet the requirements of the current production line from being idle, thereby reducing costs;
