Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotor core processing technology, specifically to a pressing and heating device for rotor core processing. Background Technology
[0002] The rotor core is usually made up of many thin layers of electrical steel sheets. During the manufacturing process, these steel sheets are precisely stacked and fixed together to form a cylindrical structure with slots in the middle for accommodating the stator windings.
[0003] In the prior art, patent document CN222735988U discloses a pressing and heating device for processing stator and rotor cores for new energy vehicles, including a frame. A servo cylinder is fixedly installed at the top of the frame, and a pressure plate is fixedly installed at the output end of the bottom of the servo cylinder. Guide posts are fixedly installed at the top of both sides of the pressure plate. The pressure plate is movably connected to the frame through the guide posts on both sides. A heating mechanism is fixedly installed at the bottom of the pressure plate. The heating mechanism includes a housing. Adjusting screws are fixedly provided at the top of both sides of the housing. The adjusting screws pass through the pressure plate and are movably connected to the pressure plate. The adjusting screws are fixed by nuts.
[0004] To address the issue that existing heating equipment can only heat a portion of a product within a certain height range when compressed, the current technology uses a snap-on plate that engages with grooves of different heights on the adjusting rod to adjust the height of the heating coil inside the housing. This allows the heating coil to be adapted to the heating needs of products of different heights. However, this method still results in the inconvenience of flexibly adjusting the position of the upper and lower heating devices during use, thus reducing the practicality of the heating device.

Detailed Implementation
[0026] The present invention will be further described in detail below with reference to embodiments: Example
[0027] like Figure 1-5 As shown, this utility model provides a pressing and heating device for machining rotor cores, including a machining table 1; a PLC controller 2 disposed on the upper surface of the machining table 1 for control; a heating unit 3 disposed on the upper surface of the machining table 1 for heating; and a pressing unit 4 disposed on the upper surface of the machining table 1 for applying pressure. The heating unit 3 includes an adjustment component disposed on the outer surface of the machining table 1 and a heating component disposed on the outer surface of the adjustment component. The pressing unit 4 includes a lifting component disposed on the upper surface of the machining table 1 and a pressing component disposed on the outer surface of the lifting component. The adjustment component includes a hydraulic cylinder 31, the outer surface of which is detachably connected to the outer surface of the machining table 1. The telescopic end of the hydraulic cylinder 31 is detachably connected to a lifting plate 33. The inner wall of the lifting plate 33 is threadedly connected to a limit bolt 35. The heating component includes a heating cover 32, the bottom surface of which is fixedly connected to the upper surface of the machining table 1. A scale 36 is fixedly connected to the outer surface of the heating cover 32. The outer surface of the heating cover 32 is connected to the limit bolt 35. The outer surface of the bolt 35 is movably snapped together, and the inner wall of the heating cover 32 is detachably connected to a heating ring 37. The heating ring 37 and the lifting plate 33 are both equipped with thermometers. The inner wall surface of the lifting plate 33 is detachably connected to a resistance wire heater 34. Multiple sets of resistance wire heaters 34 are evenly distributed inside the lifting plate 33. When using the heating equipment for rotor core processing, first rotate the limit bolt 35, and then use the PLC controller 2 to control the start hydraulic cylinder 31, which, together with the scale 36, drives the lifting plate 33 to rise and fall, thereby adjusting the height of the lifting plate 33. After adjustment, the limit bolt 35 is used to lock the position of the lifting plate 33. Finally, when heating and pressing the rotor core, the heating ring 37 and resistance wire heaters 34 inside the heating cover 32 can be activated to assist in heating the rotor core placed inside the heating cover 32. During the heating process, the temperature is monitored by the thermometer inside the heating cover 32, so that the rotor core can be heated evenly. Example
[0028] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the lifting assembly includes a limiting post 41, the bottom surface of which is fixedly connected to the upper surface of the processing table 1. A hydraulic cylinder 42 is detachably connected to the upper surface of the limiting post 41, and a lifting plate 43 is detachably connected to the telescopic end of the hydraulic cylinder 42. The pressurizing assembly includes a temperature controller 44, the bottom surface of which is detachably connected to the upper surface of the lifting plate 43. A pressing plate 45 is detachably connected to the bottom surface of the lifting plate 43. A pressure sensor is provided at the connection between the pressing plate 45 and the lifting plate 43. An electromagnetic heating plate 46 and a thermometer are detachably connected to the inner wall of the pressing plate 45. After the rotor core is placed, the hydraulic cylinder 42 can be activated to lift the lifting plate 43 on the outer surface of the limit post 41, thereby adjusting the height of the extrusion plate 45. This allows the electromagnetic heating plate 46 to enter the inner wall of the heating cover 32 and work with the lifting plate 33 to press the rotor core. During the pressing process, the electromagnetic heating plate 46 inside the extrusion plate 45 is activated to press the top of the rotor core. During the pressing process, the pressure sensor on the top of the extrusion plate 45 is used to detect the pressing force. During the pressing process, the temperature controller 44 on the top of the lifting plate 43 controls the thermometer inside the extrusion plate 45 to monitor the heating temperature.
[0029] The working principle of the pressing and heating equipment for machining the rotor core will be explained in detail below.
[0030] like Figure 1-5 As shown, when using the heating equipment for rotor core processing, first rotate the limit bolt 35, then use the PLC controller 2 to control the start of the hydraulic cylinder 31, which, together with the scale 36, drives the lifting plate 33 to rise and fall, thereby adjusting the height of the lifting plate 33. After adjustment, the limit bolt 35 is used to lock the position of the lifting plate 33. Finally, when heating and pressing the rotor core, the heating ring 37 and resistance wire heater 34 installed inside the heating cover 32 can be activated to assist in heating the rotor core placed inside the heating cover 32. During the heating process, the temperature is monitored by a thermometer installed inside the heating cover 32, thus ensuring that the rotor core is heated evenly. After the rotor core is placed, the hydraulic cylinder 42 can be activated to lift the lifting plate 43 on the outer surface of the limit post 41, thereby adjusting the height of the extrusion plate 45. This allows the electromagnetic heating plate 46 to enter the inner wall of the heating cover 32 and work with the lifting plate 33 to press the rotor core. During the pressing process, the electromagnetic heating plate 46 inside the extrusion plate 45 is activated to press the top of the rotor core. During the pressing process, the pressure sensor on the top of the extrusion plate 45 is used to detect the pressing force. During the pressing process, the temperature controller 44 on the top of the lifting plate 43 controls the thermometer inside the extrusion plate 45 to monitor the top heating temperature.
[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
