AI Technical Summary
In the existing motor lamination processing, the punching accuracy is not high and the efficiency is low, mainly due to manual operation and lamination shaking.
A stamping die structure including a first die holder, a second die holder, and a third die holder was designed. The punch sheet is fixed by a contour feeding area and a limiting stop, and the perpendicularity and stability of the punching are ensured by a guide shaft and a telescopic spring. The movement of the die holder is precisely controlled by a threaded drive to achieve automated punching.
It improves punching accuracy and efficiency, reduces manual operation, automatically discharges waste, ensures continuous production, and reduces operating difficulty and time costs.

Abstract
Claims
1. A stamping die structure for producing motor laminations, comprising a first die holder (1), a second die holder (2), and a third die holder (3) arranged sequentially at intervals, wherein the positions of the second die holder (2) and the third die holder (3) are relatively fixed, and the first die holder (1) is configured to be able to approach or move away from the second die holder (2), characterized in that: The top surface of the No. 2 mold base (2) is recessed in the middle to form a conforming feeding area (21) that fits into the shape of the stamping. Several punches (22) are opened in the middle of the conforming feeding area (21), and the punches (22) are connected vertically to the No. 2 mold base (2). The top surface of the No. 2 mold base (2) is also provided with a limiting stop (4) located on the upper side of the conforming feeding area (21). The limiting stop (4) can abut against the top surface of the stamping in the conforming feeding area (21). A stamping seat (5) is set on the first mold base (1), and several punching cutters (51) are set on the lower part of the stamping seat (5). The punching cutters (51) correspond one-to-one with the punch (22). The top surface of the No. 3 mold base (3) is provided with a material drop tube (6), which is connected to the punch (22) one by one, and its other end passes through the No. 3 mold base (3).
2. The stamping die structure for producing a motor lamination according to claim 1, wherein At least four guide shafts (7) are connected together between the No. 1 mold base (1), the No. 2 mold base (2), and the No. 3 mold base (3). The No. 1 mold base (1) is movably sleeved on the guide shaft (7) through a bushing. A stop (71) is provided at the top of the guide shaft (7) to restrict the upward movement of the No. 1 mold base (1). A telescopic spring (72) is sleeved on the guide shaft (7) located between the No. 1 mold base (1) and the No. 2 mold base (2).
3. The stamping die structure for producing a motor lamination according to claim 2, wherein The second mold base (2) is movably sleeved on the guide shaft (7). The third mold base (3) is provided with a screw rod (8), which is threaded to the second mold base (2). The screw rod (8) is provided with fastening nuts (81) located on the top and bottom surfaces of the second mold base (2).
4. The stamping die structure for producing a motor lamination according to claim 3, wherein A second telescopic spring (73) is fitted onto the guide shaft (7) located between the second mold base (2) and the third mold base (3).
5. The stamping die structure for producing a motor lamination according to claim 3, wherein The first mold base (1) is provided with a bayonet (11), which allows the top of the screw (8) to pass through, and the size of the bayonet (11) is larger than the size of the fastening nut (81).
6. The stamping die structure for producing a motor lamination according to claim 1, wherein The contour feeding area (21) is circular, and the several punches (22) within the contour feeding area (21) are arranged in an array.
7. The stamping die structure for producing a motor lamination according to claim 6, wherein The top surface of the second mold base (2) is recessed on both sides with notches (23), and the notches (23) are connected to the contour feeding area (21).
