Description

Technical Field

[0001] This utility model relates to the field of steel belt conveying technology, and in particular to a stator core silicon steel belt punching and conveying equipment. Background Technology

[0002] With the rapid development of green energy industries such as electric vehicles and wind power, the stator core, as a core component of motors, is becoming increasingly important. The stator core is mainly manufactured from silicon steel strip through processes such as stamping and winding. It is used to manufacture the stator section of motors, serving to conduct magnetic fields and improve motor efficiency. Silicon steel strip has high magnetic permeability and low energy loss, thus becoming a key material for manufacturing motor stators.

[0003] In the manufacturing process of stator cores, the processing accuracy and transmission stability of silicon steel strips are crucial to the final motor performance. During the punching process, silicon steel strips typically require complex conveying and guiding to ensure that the strip does not shift, deform, or result in waste. Traditional conveying equipment often relies on manual adjustment and relatively crude mechanical guiding methods, which not only reduces production efficiency but may also cause unnecessary damage to the silicon steel strip, thus affecting the quality of the final product.

[0004] Currently, most stator core silicon steel strip punching and conveying equipment on the market mainly adopts a simple conveying system and manual adjustment method, which has some problems and defects.

[0005] Insufficient guidance accuracy:

[0006] Traditional conveyor systems are relatively simple in design, often relying on a few fixed rollers and clamps to ensure the transmission path of the silicon steel strip. This type of system struggles to maintain good guiding accuracy at high speeds, causing the strip to easily deviate during transmission and affecting subsequent punching processes. Especially when the silicon steel strip is thin and easily deformed, insufficient guiding accuracy can lead to strip deformation, wrinkling, or even jamming.

[0007] Poor transmission stability:

[0008] Most existing conveyor systems rely on relatively simple motor drives and belt drives, which fail to effectively balance the tension fluctuations generated during the conveying process. Due to the special properties of silicon steel belts, they are highly susceptible to excessive or insufficient tension during conveying, leading to damage or waste of the belt material.

[0009] Poor adaptability:

[0010] Traditional equipment has poor adaptability and can usually only be used for silicon steel strips of a certain specification and size. It is not flexible enough to adjust to strips of different thicknesses or widths, resulting in frequent adjustments during the production process and reduced work efficiency.

[0011] Therefore, it is essential to invent a stator core silicon steel strip punching and conveying device. Utility Model Content

[0012] To address the aforementioned technical problems, this utility model provides a stator core silicon steel strip punching and conveying device, which solves the problems of insufficient guiding accuracy, poor transmission stability, and poor adaptability that still exist in existing structures. A stator core silicon steel strip punching and conveying device includes a support base plate, a coil support, a silicon steel coil, a support platform, a guiding and conveying structure, a driving and conveying structure, and a stamping and guiding structure. The coil support is fixedly installed at one end of the support base plate surface, and the support platform is fixedly installed at the other end of the support base plate surface. The silicon steel coil is rotatably mounted on the coil support, and the guiding and conveying structure is fixedly installed on the outer side of the support platform near the coil support end. The driving and conveying structure is fixedly installed above the support platform near the coil support end. The stamping and guiding structure is fixedly installed on the top of the support platform.

[0013] The guiding and transmission structure includes a support frame, a power spindle, a guide shaft assembly, and a guide shaft. The support frame is fixedly installed on the outer side of the support platform near the material roll support. The power spindle is rotatably installed in the middle position inside the support frame. The guide shaft assembly is rotatably installed above the support frame and is driven by the power spindle via a belt. The guide shaft is rotatably installed at the top of the support frame.

[0014] The stamping guide structure includes a support housing, a first power roller, a second power roller, a lower support shaft, a movable bracket, an upper support shaft, and a pressure push rod. The support housing is fixedly installed on the top of the support platform, and the first and second power rollers are rotatably installed at both ends of the support housing. The lower support shaft is rotatably installed below the middle position of the support housing, and the movable bracket is slidably installed above the middle position of the support housing. The upper support shaft is rotatably installed below the movable bracket. The pressure push rod is fixedly installed on the top of the support housing and connected and fixed to the movable bracket.

[0015] The internal support frame of the guiding transmission structure uses two sets of curved metal plates, and several guide shaft groups are evenly distributed on the curved surface of the support frame in an arc arrangement. One end of the power spindle is driven by a motor to rotate, and through a belt, it drives several guide shaft groups to rotate in the same direction. This has the following functions: ① Guiding the movement of the silicon steel belt: The guiding transmission structure effectively guides the silicon steel belt to run smoothly along a predetermined path through guide shaft groups and guide shafts, ensuring the accurate direction of the belt during transport; ② Stabilizing the tension of the silicon steel belt: During transport, the guiding transmission structure helps maintain appropriate tension in the silicon steel belt, preventing deformation, wrinkling, or breakage due to excessive tightness or looseness; ③ Synchronizing the movement of the belt: The power spindle is connected to the guide shaft groups through a belt drive system, ensuring that multiple guide shaft groups can rotate synchronously, allowing the silicon steel belt to be transported evenly and smoothly; ④ Preventing the silicon steel belt from deviating: Through the arrangement of the curved support frame and guide shafts, the guiding transmission structure ensures that the silicon steel belt moves along a predetermined trajectory, preventing the belt from deviating due to external forces or uneven friction.

[0016] The first power roller, the second power roller, and the lower support shaft inside the stamping guide structure are all driven to rotate by a motor; the upper support shaft can be moved away from or closer to the lower support shaft by a pressure push rod; the lower support shaft and the upper support shaft clamp the silicon steel coil, and the silicon steel coil is moved forward by the power of the first power roller, the second power roller, and the lower support shaft; the silicon steel coil output from the second power roller moves into the punching equipment, which has the following functions: ① Stabilize the transmission direction of the silicon steel strip: the stamping guide structure ensures that the silicon steel strip runs stably along the correct trajectory before entering the punching equipment through its precise guiding function. It helps prevent the strip from deviating from the track, preventing misalignment or jamming, thus ensuring the accuracy of subsequent punching processes; ② Smooth conveying: The first and second power rollers drive the movement of the silicon steel strip by rotation, ensuring stable transmission of the strip during the punching process. The lower and upper support shafts clamp the silicon steel strip, forming a clamping device to ensure that the strip does not slip or deviate during the conveying process, maintaining smooth conveying to the punching equipment; ③ High-efficiency conveying: The first and second power rollers and the lower support shaft are all driven by motors, enabling the silicon steel strip to be continuously and smoothly conveyed into the punching equipment. In this way, the stamping guide structure ensures the high efficiency and stability of the transmission.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

It helps to prevent the strip from deviating from the track, preventing problems such as misalignment or jamming, thereby ensuring the accuracy of subsequent punching processes; ②

[0022] Smooth conveying: The first and second power rollers rotate to move the silicon steel strip, ensuring stable conveying of the strip during the punching process. The lower and upper support shafts clamp the silicon steel strip, forming a clamping device to ensure that the strip does not slip or deviate during conveying, maintaining a smooth conveyance to the punching equipment. ③ High-efficiency conveying: The first and second power rollers, as well as the lower support shaft, are all driven by motors, enabling the silicon steel strip to be continuously and smoothly conveyed into the punching equipment.
