Description

Technical Field

[0001] The utility model relates to the technical field of magnetic suspension long stator manufacturing, in particular to a heating and pressurizing mechanism in the primary solidification process of a magnetic suspension long stator product. Background Art

[0002] Magnetic levitation rail transit technology is based on the principle of long-stator linear motors. The train is the rotor, propelled linearly by the long stator's electromagnetic field. The long stator includes long stator coils, which are one of the core components of magnetic levitation rail transit. A single long stator section is made of 180 stacked iron cores, which are then cast and cured with epoxy resin. The long stator is typically about one meter long and has a large packaging area, requiring the epoxy resin encapsulation to have an average thickness of 1-1.5mm and a relatively thin wall. Epoxy resin is a thermosetting material and requires heating to cure. The existing process involves transferring the assembled mold to a vacuum casting tank after the product is molded, evacuating the mold, and then pouring the epoxy resin. After pouring, the vacuum in the vacuum casting tank is broken. The mold filled with raw materials is then moved to a curing oven for curing and molding. The curing oven currently designed only has a heating function. When pouring epoxy resin, there may be residual gas inside the mold. The residual gas cannot be discharged outside the mold during curing, causing surface and internal defects, requiring secondary repairs, resulting in a low pass rate for the product after demoulding, or even causing it to be scrapped in severe cases.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0034] In the description of the present invention, it should be understood that descriptions involving orientation, such as the orientation or positional relationship indicated by up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0036] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0037] Reference Figures 1 to 3As shown, a heating and pressurizing mechanism for the primary curing process of a magnetically suspended long stator product according to one embodiment of the present invention comprises: a pressurized tank body 100, a tank cover 200, a heating device 300, and an exhaust control valve 500. The pressurized tank body 100 is cylindrical with one end open. The opening of the pressurized tank body 100 can be used to remove and insert a workpiece. The workpiece is a magnetically suspended long stator, which is placed into the pressurized tank body 100 after undergoing a vacuum casting process with epoxy resin. The tank cover 200 is detachably mounted at the opening of the pressurized tank body 100. When the tank cover 200 is open, the opening of the pressurized tank body 100 is used to insert and remove the workpiece. When the tank cover 200 is closed, the pressurized tank body 100 is sealed; the function of the tank cover 200 is to seal the opening of the pressurized tank body 100. The heating device 300 is connected to a compressed air source, which provides compressed air to the heating device 300. The compressed air pressure is at least 0.7 MPa. The heating device 300 is connected to the pressurized tank 100 via an air inlet pipe 400. It is used to heat the compressed air entering the pressurized tank 100. After being heated to 130 to 200 degrees Celsius in the heating device 300, the compressed air enters the pressurized tank 100 to heat the workpiece. An exhaust control valve 500 is connected to the pressurized tank 100 and controls the flow of air out of the pressurized tank 100 to maintain the pressure within the pressurized tank 100 at a preset value. When the exhaust control valve 500 is closed, the compressed air entering the pressurized tank 100 not only heats the workpiece but also pressurizes it. The exhaust control valve 500 can be a relief valve or a check valve with an opening pressure of 0.25 MPa to control the air pressure within the pressurized tank 100. A safety valve 900 is connected to the pressurized tank 100 and opens to release pressure when the pressure within the pressurized tank 100 reaches a preset value. The opening pressure of the pressurized tank body 100 is 0.3 MPa, which prevents the internal pressure of the pressurized tank body 100 from being too high.

[0038] Multiple exhaust control valves 500 can be set to allow air to flow fully in the pressurized tank body 100. The workpiece is heated to solidify the epoxy resin. Due to the increase in pressure, the volume of bubbles in the epoxy resin is compressed less, and the external pressure can better compensate for the shrinkage caused by the epoxy resin during solidification, which is beneficial to reducing pores and cracks in the epoxy resin and improving the solidification quality of the workpiece.

[0039] Reference Figures 1 to 3 As shown, it is understood that a support rod 600 is provided on the top of the pressurized tank body 100, and the tank cover 200 is rotatably mounted on the support rod 600. The support rod 600 is used to drive the tank cover 200 toward and away from the pressurized tank body 100, so as to facilitate the convenient and rapid opening and closing of the tank cover 200. The connection method between the tank cover 200 and the pressurized tank body 100 and the specific structure and installation method of the support rod 600 are all prior art and will not be described in detail.

[0040] Reference Figures 1 to 3 As shown, it can be understood that a temperature-controlled water jacket 700 is provided on the outside of the pressurized tank body 100. The temperature-controlled water jacket 700 can be welded to the outside of the pressurized tank body 100 or bolted to the outside of the pressurized tank body 100. The temperature-controlled water jacket 700 is used to heat and cool the pressurized tank body 100. The temperature-controlled water jacket 700 preheats the pressurized tank body 100 before placing the workpiece, reducing the time required for compressed air heating and improving the uniformity of the temperature inside the pressurized tank body 100. This allows the epoxy resin in the workpiece to be evenly heated, thereby improving the curing quality. The temperature-controlled water jacket 700 can also cool the pressurized tank body 100 before removing the workpiece, making it easier for the staff to remove the workpiece. It can also increase the cooling rate of the workpiece so that the workpiece can quickly enter the next process.

[0041] Reference Figures 1 to 3 As shown, it can be understood that the temperature control water jacket 700 is provided with a flow channel 710, which is evenly distributed within the temperature control water jacket 700. The flow channel 710 is connected to the tank body circulating water pump 712 through the water jacket inlet pipe 711. The tank body circulating water pump 712 is a centrifugal pump. The tank body circulating water pump 712 is connected to an intermediate buffer water tank 713, which acts as a buffer. The height of the tank body circulating water pump 712 is greater than that of the intermediate buffer water tank 713. Gravity is used to provide sufficient inlet pressure to ensure the normal operation of the tank body circulating water pump 712. The tank circulation water pump 712 is used to drive the coolant to circulate within the intermediate buffer water tank 713 and the flow channel 710. The jacket outlet pipe 701 is connected to a heat pump unit 800 for cooling and heating the coolant. The flow channel 710 is connected to the heat pump unit 800 via the jacket outlet pipe 701. The heat pump unit 800 outputs the heated or cooled coolant to the intermediate buffer water tank 713 via the jacket inlet pipe 711. The specific structure and installation method of the heat pump unit 800 are prior art and have been disclosed in Chinese Utility Model Patent Publication No. CN100529590C, so they will not be described in detail. The heat pump unit 800 has a first operating mode for heating the coolant from the jacket inlet pipe 711 and a second operating mode for cooling the coolant from the jacket inlet pipe 711. Only one heat pump unit 800 is required to achieve both heating and cooling functions, which helps reduce equipment size and equipment investment costs.

[0042] Reference Figures 1 to 3As shown, it can be understood that the heat pump unit 800 is connected to the heat storage device 830 via a heat pump circulation inlet pipe 810 and a heat pump circulation outlet pipe 820. The heat pump circulation inlet pipe 810 is equipped with a heat storage circulation water pump 840, which is used to drive the coolant to circulate between the heat storage device 830 and the heat pump unit 800. In the first operating mode, the heat pump unit 800 transfers heat from the heat storage device 830 to the temperature control water jacket 700. In the second operating mode, the heat pump unit 800 transfers heat from the temperature control water jacket 700 to the heat storage device 830. The heat storage device 830 is prior art and is disclosed in Chinese Utility Model Patent Publication No. CN100410598C, so it will not be described in detail. Using the heat storage device 830 to transfer heat helps save energy consumption during the cooling and heating cycles of the pressurized tank 100, effectively reducing operating costs.

[0043] Reference Figures 1 to 3 As shown, it can be understood that the heating device 300 includes a main heater 310 and an electric heating wire heater 320. The compressed air is first heated by the main heater 310, and then heated by the electric heating wire heater 320 before entering the pressurized tank body 100. The heat source of the main heater 310 can use steam or a gas boiler. The heating power of the main heater 310 is greater than the heating power of the electric heating wire heater 320. The heating device 300 is divided into a main heater 310 and an electric heating wire heater 320 connected in series, where most of the heat for heating the air comes from the main heater 310. The main heater 310 uses a steam heat source or a gas boiler heat source. Compared with the use of electric heating, it generally has the advantage of low unit energy consumption cost, but has the disadvantage of adjustment lag and difficulty in accurately controlling the heating temperature. The electric heating wire heater 320 has the characteristics of low thermal inertia and high adjustment sensitivity, so it plays the role of adjusting the temperature of the compressed air entering the pressurized tank body 100. The main heater 310 and the electric heating wire heater 320 are used together, which saves operating costs and helps to accurately control the heated temperature of the workpiece and improve the curing quality by adjusting the heating power of the electric heating wire heater 320.

[0044] Reference Figures 1 to 3As shown, it can be understood that the heat pump unit 800 is connected to the auxiliary heater 870 through the auxiliary heating inlet pipe 850 and the auxiliary heating outlet pipe 860. The auxiliary heating inlet pipe 850 is provided with an auxiliary heating circulating water pump 880. The auxiliary heating inlet pipe 850 and the auxiliary heating outlet pipe 860 are both provided with valves to control the circulation of the coolant. When the auxiliary heater 870 is not in use, the valve can be closed. The heat pump unit 800 can circulate and heat the coolant flowing through the auxiliary heater 870 through the auxiliary heating inlet pipe 850 and the auxiliary heating outlet pipe 860. When the heat pump unit 800 is in the first working mode, the auxiliary heater 870 can heat the compressed air and deliver it to the electric heating wire heater 320. The electric heating wire heater 320 adjusts the temperature of the compressed air and delivers it to the pressurized tank 100 to heat the workpiece. At this time, the main heater 310 does not need to work or only needs to output a lower power to reduce energy consumption. When the heat pump unit 800 is in the second operating mode, the auxiliary heater 870 cools the compressed air and delivers it to the electric heating wire heater 320, which no longer heats the compressed air. The cold compressed air entering the pressurized tank 100 quickly cools the workpiece, facilitating its rapid removal to the next process and improving production efficiency.

[0045] Reference Figures 1 to 3 As shown, it is understood that the highest point of flow channel 710 is connected to a pressure reducing pipeline 702, which is equipped with a pressure reducing valve 703. Pressure reducing pipeline 702 is connected to an intermediate buffer water tank 713, which is located at a lower height than the pressurized tank 100. During initial startup, air in flow channel 710 may accumulate at the highest point due to density. In this case, the air inside flow channel 710 can be discharged through pressure reducing pipeline 702 by opening pressure reducing valve 703. In situations where safety requirements are high, pressure reducing valve 703 can also be designed as a relief valve with an opening pressure of 1 MPa to relieve pressure in the event of a fault and prevent excessive pressure in flow channel 710.

[0046] Reference Figures 1 to 3 As shown, it is understood that a vent pipe 704 is connected to the pressure reducing pipeline 702, which is in communication with the outside atmosphere. A vent valve 714 is provided on the vent pipe 704. A drain pipe 715 is connected to the lowest point of the flow channel 710. This drain pipe 715 is connected to the intermediate buffer water tank 713 and is equipped with a drain valve 716. When the flow channel 710 is to be inspected or cleaned, the coolant in the flow channel 710 needs to be drained. At this time, the vent valve 714 and drain valve 716 can be opened to allow gravity to drain the coolant in the flow channel 710 into the intermediate buffer water tank 713.

[0047] Reference Figures 1 to 3As shown, it can be understood that a pressure gauge 110 is provided on the pressurized tank body 100 , and the pressure gauge 110 is used to measure the pressure inside the pressurized tank body 100 .

[0048] Usage steps: put the workpiece into the pressurized tank body 100, close the tank cover 200, start the tank body circulating water pump 712, the tank body circulating water pump 712 drives the coolant to circulate between the temperature control water jacket 700 and the heat pump unit 800, start the heat storage circulating water pump 840, the tank body circulating water pump 712 drives the coolant to circulate between the heat storage device 830 and the heat pump unit 800, the heat pump unit 800 switches to the first working mode, transfers the heat in the heat storage device 830 to the temperature control water jacket 700, raises the temperature of the pressurized tank body 100 to the preset value, and then opens the corresponding valve to make the heat pump unit The higher-temperature coolant output by 800 is delivered to the auxiliary heater 870 via the auxiliary heating circulating water pump 880 to heat the compressed air. The main heater 310 heats the compressed air, and the compressed air heated by the main heater 310 and the auxiliary heater 870 mix and then enter the electric heating wire heater 320. The electric heating wire heater 320 heats the compressed air to a preset value and then delivers it to the pressurized tank 100 to heat the workpiece. The exhaust control valve 500 opens to release pressure when the air pressure in the pressurized tank 100 reaches 0.25 MPa to maintain a constant air pressure in the pressurized tank 100. After the temperature in the heat storage device 830 drops to a specified value, the heat pump unit 800, the tank circulating water pump 712, the heat storage circulating water pump 840, and the auxiliary heating circulating water pump 880 are shut down, and the compressed air is primarily heated by the main heater 310. After two hours, the heating wire heater 320 and the main heater 310 stop heating the compressed air, and the heat pump unit 800, the tank circulating water pump 712, the thermal storage circulating water pump 840, and the auxiliary heating circulating water pump 880 are activated. The heat pump unit 800 switches to the second operating mode, cooling both the pressurized tank 100 and the compressed air, and transferring the heat to the thermal storage device 830. After the temperature inside the pressurized tank 100 drops to room temperature, the exhaust control valve 500 opens to reduce the pressure inside the pressurized tank 100 to zero. The tank lid 200 is then opened, and the workpiece is removed.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
