Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a device for stacking and sorting laminations in an in-mold for motor stator and rotor laminations. Background Technology

[0002] The iron core in the stator and rotor of the motor is made of stacked laminations. The laminations are formed by stamping with a die. During the stamping process, the laminations fall out of the die and then fall directly onto the conveyor belt. They are then transported out by the conveyor belt. The laminations are scattered on the conveyor belt and need to be sorted manually afterward. Sometimes the stamping speed of the die is fast and manual sorting cannot keep up with the production rhythm, which is not only inefficient but also easy to cause material to accumulate on the conveyor belt. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A lamination stacking and sorting device for motor stator and rotor laminations includes a lower die base with a blanking hole machined therein. An upper stepped hole and a lower stepped hole are respectively provided above and below the blanking hole. A locking ring is installed in the upper stepped hole, and a receiving positioning seat is installed in the lower stepped hole. An upper mounting groove and a lower mounting groove are respectively machined on the upper and lower end faces of the receiving positioning seat. A first-stage receiving force transmission plate and a second-stage receiving force transmission plate are respectively installed in the upper and lower mounting grooves. Upper receiving block mounting grooves are evenly distributed at the bottom of the upper mounting groove, and upper receiving blocks are connected to the upper receiving block mounting grooves. The lower mounting... The bottom of the loading slot is evenly distributed with lower receiving block mounting slots, and lower receiving blocks are connected in the lower receiving block mounting slots. Guide pins are connected to the surfaces of the upper receiving blocks and the lower receiving blocks.

[0006] Furthermore, the bottom of the lower mounting groove is evenly distributed with countersunk holes, and bolts and positioning pins are inserted through the countersunk holes to connect with the lower mold base and fix the material receiving positioning seat.

[0007] Furthermore, the first-stage material receiving and force transmission plate is provided with a waist-shaped clearance groove for clearance bolts and positioning pins.

[0008] Furthermore, an upper cover plate and a lower cover plate are respectively installed on the upper and lower end faces of the receiving and positioning seat, and a material dropping hole is machined in the middle of the upper and lower cover plates.

[0009] Furthermore, the upper and lower material receiving block mounting slots are fully open to the side facing the material discharge hole.

Detailed Implementation

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0018] like Figure 1 As shown, a device for stacking and sorting motor stator and rotor laminations in an in-mold includes a lower die base 1. The lower die base 1 has a blanking hole machined inside. An upper stepped hole and a lower stepped hole are respectively provided above and below the blanking hole. A locking ring 2 is provided in the upper stepped hole. A baffle hole is machined in the middle of the locking ring 2. The diameter of the baffle hole is 0.01 to 0.05 mm smaller than the outer diameter of the lamination. In this way, during the stamping process, the stamped laminations are blocked by the baffle hole. When subjected to pressure from above, the laminations fall one by one from below the baffle hole.

[0019] A receiving positioning seat 3 is provided in the lower step hole. The upper and lower end faces of the receiving positioning seat 3 are respectively machined with an annular upper mounting groove 4 and an annular lower mounting groove 5. An upper cover plate 6 and a lower cover plate 7 are also installed on the upper and lower end faces of the receiving positioning seat 3 to block the upper mounting groove 4 and the lower mounting groove 5. Before installing the lower cover plate 7, the receiving positioning seat 3 together with the upper cover plate 6 is fixed to the lower mold base 1. The bottom of the lower mounting groove 5 is evenly distributed with countersunk holes. Bolts 8 and positioning pins 9 are inserted through the countersunk holes. The bolts 8 and positioning pins 9 pass through the upper cover plate 6 and connect with the lower mold base 1 to fix the receiving positioning seat 3.

[0020] A blanking hole is machined between the upper cover plate 6 and the lower cover plate 7, which is used for passing through the punch.

[0021] An annular first-stage material receiving force transmission plate 10 and an annular second-stage material receiving force transmission plate 11 are respectively installed in the upper mounting groove 4 and the lower mounting groove 5, such as... Figure 2 As shown, the bottom of the upper mounting groove 4 has four upper receiving block mounting grooves evenly distributed, and each upper receiving block mounting groove is connected to an upper receiving block 12, as shown. Figure 3 As shown, four lower receiving block mounting slots are evenly distributed at the bottom of the lower mounting slot 5. Lower receiving blocks 13 are connected in the lower receiving block mounting slots. Guide pins 14 are connected to the surfaces of the upper receiving block 12 and the lower receiving block 13. Guide slots 15 are opened on the first-stage receiving force transmission plate 10 and the second-stage receiving force transmission plate 11. At the same time, the first-stage receiving force transmission plate 10 is also provided with a waist-shaped clearance slot 16 for the clearance bolt 8 and the positioning pin 9. The guide pin 14 is inserted into the guide slot 15.

[0022] An upper cylinder 17 and a lower cylinder 18 are installed around the lower step hole. A notch is provided around the material receiving positioning seat 3. Ear plates 19 are provided around the first-stage material receiving force transmission plate 10 and the second-stage material receiving force transmission plate 11. The ear plates 19 pass through the notch. The piston ends of the upper cylinder 17 and the lower cylinder 18 are connected to the corresponding ear plates 19 through a pull plate 20. In order to make the piston push smoothly, a guide screw 21 is installed around the lower step hole. The guide screw 21 passes through the guide groove 22 on the ear plate 19.

[0023] During the stamping process, the stamping pieces fall from top to bottom. After being slowly locked by the locking ring 1, they fall sequentially under the action of external force. The upper cylinder 17 pushes the first-stage receiving force transmission plate 10, which rotates and transmits torque, causing the upper receiving block 12 to move forward. Since the upper and lower receiving block mounting slots are fully open to the side facing the discharge hole, the upper receiving block 12 extends out of the upper receiving block mounting slot and extends into the receiving positioning seat 3, blocking the stamping pieces on this layer for waiting and stacking upwards. When the products are stacked to a certain height, the piston of the upper cylinder 17 retracts, causing the upper receiving block 12 to move backwards and hide in the receiving positioning seat 3, so that the stacked products fall downwards onto the lower receiving block 13. Then the lower cylinder 18 retracts, causing the lower receiving block 13 to move and hide in the receiving positioning seat 3, so that the stacked stamping pieces fall onto the conveyor belt and are conveyed backwards.

[0024] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
