Description

Technical Field

[0001] This utility model relates to the technical field of iron core stamping, and in particular to an iron core stamping device for new energy motors. Background Technology

[0002] The motor cores in segmented staggered stacked iron core motors for new energy engineering machinery (such as buses, lifting and hoisting machinery, etc.) have the following main characteristics: various lamination types, complex lamination structure, large lamination outer diameter, and small differences between various lamination types. During stamping, the progressive stamping die needs to stamp multiple lamination types in multiple stations in steps, resulting in excessively long die lengths, strict or unmet requirements for stamping equipment specifications, increased die manufacturing costs, and extended production cycles. Utility Model Content

[0003] In view of the shortcomings and defects of the existing technology, a new energy motor core stamping device is provided. In order to achieve the purpose of punching out different parts of the sheet shape by rotating the fixed plate, the present invention provides the following technical solution.

[0004] A stamping device for a new energy motor core includes an upper die base, a lower die base, and a strip material. The upper die base includes an upper template, a stripper plate, and a punch. The lower die base includes a die fixing plate, a die assembly, and a rotating handle. The die assembly is disposed within the die fixing plate and includes a die template, a rotating shaft, and a rotating fixing plate. The rotating handle is connected to the rotating fixing plate, and the rotating fixing plate is sleeved on the rotating shaft. The die template is disposed at the upper end of the rotating shaft. In the initial state, the punch presses the strip material towards the die direction to form a first piece. By rotating the rotating handle, the rotating fixing plate rotates around the rotating shaft. When the rotating fixing plate rotates in a first direction, the punch presses the strip material to form a second piece. When the rotating fixing plate rotates in a second direction, the punch presses the strip material to form a third piece.

[0005] Compared with the prior art, this utility model solves the stamping differences between various sheet types by rotating the fixed plate to punch out different parts of the sheet type; and by adopting a separate connection method between the fixed plate and the rotating shaft, it solves the technical problems of difficult integral processing and poor processing accuracy. By adding a precision positioning rotary body to manually rotate to a specified angle, it is possible to quickly switch between stamping of three sheet types, which greatly improves production efficiency.

[0006] Furthermore, a first limiting block is provided on one side of the rotating fixing plate and a second limiting block is provided on the other side. When the rotating fixing plate abuts against the first limiting block, the rotating fixing plate rotates to the limit position in the first direction to form a second piece. When the rotating fixing plate abuts against the second limiting block, the rotating fixing plate rotates to the limit position in the second direction to form a third piece.

[0007] Through the above improvements, by setting a first limiting block and a second limiting block on both sides of the rotating fixing plate, the rotating shaft rotates to the desired position by the abutting of the rotating fixing block against the first or second limiting block, thus preventing excessive rotation that could compromise the product forming effect.

[0008] Furthermore, the rotating fixing plate is provided with a first positioning pin and a second positioning pin. When the rotating fixing plate abuts against the first limiting block, the first positioning pin is fixed on the rotating fixing plate. When the rotating fixing plate abuts against the second limiting block, the second positioning pin is fixed on the rotating fixing plate.

[0009] Through the above improvements, a first positioning pin and a second positioning pin are provided on the rotating fixed plate. The first positioning pin and the second positioning pin can enable the rotating fixed plate to maintain stability after rotating to the limit position.

[0010] Furthermore, the rotating shaft is fixed to the rotating fixed plate by bolts.

[0011] Through the above improvements, the rotating shaft and the rotating fixed plate are fixed together by bolts, so that the rotation of the rotating shaft and the rotating fixed plate are kept synchronized, preventing the rotating fixed plate and the rotating shaft from deflecting and thus affecting the molding of the final product.

[0012] Furthermore, the die fixing plate is provided with a mating cavity, and a needle roller positioning sleeve is provided in the mating cavity. The inner side of the needle roller positioning sleeve is mated with the outer wall of the rotating shaft.

[0013] Through the above improvements, a needle roller positioning sleeve is provided inside the die fixing plate. The needle roller positioning sleeve can easily fix the rotating shaft and the rotating fixing plate during rotation, thereby improving the stability of the stamped product.

[0014] Furthermore, a waste hole is provided at the center of the rotating shaft, and the waste hole is provided corresponding to the concave template.

[0015] With the above improvements, a waste hole is provided at the center of the rotating shaft, which facilitates the discharge of waste after molding. Attached Figure Description

In the initial state, the punch 1.3 presses the strip 3 in the direction of the die to form the first piece 3.1. The rotating handle 2.3 is turned to drive the rotating fixed plate 2.23 to rotate around the rotating shaft 2.22. The rotating fixed plate 2.23 rotates in the first direction X, and the punch 1.3 presses the strip 3 to form the second piece 3.2.

[0022] A first limiting block 4 is provided on one side of the rotating fixing plate 2.23, and a second limiting block 5 is provided on the other side.
