Description

Technical Field

[0001] This invention relates to the field of rotor lamination production technology, specifically to a device for producing rotor laminations. Background Technology

[0002] As is well known, in the manufacturing process of an electric motor, both the stator and rotor are formed by stacking and pressing stamped laminations. The silicon steel sheets used for the stator and rotor laminations are manufactured according to specifications to form the first transmission gear disc 00. The first drive gear plate contains a large coil of silicon steel sheet about 50mm in diameter. The silicon steel sheet is continuously transported on the stamping device, which can stamp the silicon steel sheet to form rotor blades.

[0003] In existing stamping equipment, the silicon steel sheets are unstable at the upper limit of the stamping device, which makes the position of the silicon steel sheets unstable on the stamping device. This affects the stamping quality of the silicon steel sheets, increases the generation of waste, and wastes resources. Therefore, in view of the above situation, there is an urgent need to develop a rotor lamination production device to overcome the shortcomings in current practical applications. Summary of the Invention

[0004] The purpose of this invention is to provide an apparatus for producing rotor laminations, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An apparatus for producing rotor laminations, comprising: A support platform and a fixing frame, wherein the fixing frame is fixedly connected to the support platform; A mold base is disposed between the support platform and the fixed frame, and is fixedly connected to the support platform; A support base is symmetrically arranged on both sides of the mold base and fixedly connected to the support platform to cooperate with the mold base to support the silicon steel sheet; A stamping machine is located outside the mold base, fixedly connected to the fixed frame, and opposite to the mold base, for use in conjunction with the mold base to stamp silicon steel sheets; A conveying mechanism is located outside the support base, connected to the fixed frame, and connected to the support platform, and is used to cooperate with the support base to convey silicon steel sheets. A limiting component is symmetrically arranged on both sides of the mold base, connected to the fixing frame and the conveying mechanism, and is used to cooperate with the conveying mechanism to achieve lateral limiting of the silicon steel sheet; The conveying mechanism includes: A control component is located inside the support platform and connected to the limiting component, used to drive the limiting component; A positioning component is disposed opposite to the support base, connected to the fixing frame, and connected to the control component, and is used to cooperate with the control component and the support base to achieve longitudinal positioning of the silicon steel sheet; A transmission assembly is disposed between the positioning assembly and the control assembly, and is used to cooperate with the control assembly to realize the automatic conveying of silicon steel sheets.

[0006] Compared with the prior art, the beneficial effects of the present invention are: During operation, the control component drives the positioning and limiting components. The positioning component, in conjunction with the support base, achieves longitudinal limiting of the silicon steel sheet, while the limiting components achieve lateral limiting of the silicon steel sheet from both sides, thus ensuring the stability of the silicon steel sheet to be processed. The control component can also drive the positioning component through the transmission component. The positioning component, in conjunction with the support base, enables the automatic movement of the silicon steel sheet. The stamping machine, in conjunction with the die holder, can stamp the silicon steel sheet. Compared with the prior art, where the silicon steel sheet is unstable at the upper limit of the stamping device during use, resulting in an unstable position of the silicon steel sheet on the stamping device, it affects the stamping quality of the silicon steel sheet, increases waste, and wastes resources. By setting up a conveying mechanism and limiting components, the silicon steel sheet can be limited laterally and longitudinally, making the silicon steel sheet more stable during processing, improving the stamping quality of the silicon steel sheet by the stamping device, reducing waste, and saving resources.

The top ends of the support rollers are flush with the top end of the mold base 4. During operation, the control component drives the positioning component and the limiting component. The positioning component, in conjunction with the support base 2, achieves longitudinal limiting of the silicon steel sheet, while the limiting component achieves lateral limiting of the silicon steel sheet from both sides, thereby ensuring the stability of the silicon steel sheet to be processed. The control component can also drive the positioning component through the transmission component. The positioning component, in conjunction with the support base 2, enables the silicon steel sheet to be processed... The automatic movement of the steel sheet, combined with the stamping machine 5 and the mold base 4, enables the stamping of silicon steel sheets. Compared with the prior art, where the silicon steel sheet is unstable at the upper limit of the stamping device during use, resulting in an unstable position of the silicon steel sheet on the stamping device, it affects the stamping quality of the silicon steel sheet, increases waste, and wastes resources. By setting a conveying mechanism and limiting components, the silicon steel sheet can be limited laterally and longitudinally, making the silicon steel sheet more stable during processing, improving the stamping quality of the silicon steel sheet, reducing waste, and saving resources.

Outside air enters the inner side of the air guide box 33 along the air intake pipe. The filter layer purifies the air. The purified air enters the inner side of the fixed pipe 31 along the second connecting pipe 29 and is discharged from the dust blowing pipe 32, removing dust from the surface of the silicon steel sheet to be processed, which is beneficial to improving the quality of the rotor lamination.

[0028] This rotor lamination production apparatus, by incorporating a conveying mechanism and limiting components, can provide lateral and longitudinal limiting for silicon steel sheets, making the sheets more stable during processing, improving the stamping quality of the silicon steel sheets, reducing waste, and saving resources. The control components can drive the positioning and limiting components, and the transmission components can drive the positioning components, ensuring the stability of the silicon steel sheets during conveying and improving the stamping quality. The positioning components, in conjunction with the control components, can achieve longitudinal control of the silicon steel sheets.

By setting the transmission component, it can cooperate with the control component to drive the positioning component to realize the automatic conveying of the silicon steel sheet, which helps to improve the processing efficiency of the device. By setting the limiting component, when the first piston 13 moves, it will drive the second piston to move inside the piston groove 40. The second piston drives the limiting frame 37 to move through the positioning rod. The limiting rollers 38 inside the limiting frames 37 on both sides abut against the silicon steel sheet from both ends, and laterally limit the silicon steel sheet to prevent the silicon steel sheet from being misaligned during the conveying process.
