Description

Technical Field

[0001] The utility model relates to the field of shaping tooling, in particular to an outer circle positioning and shaping device for an air suspension iron core. Background Art

[0002] The iron core is formed by laminating multiple silicon steel sheets. In the motor field, it includes a stator iron core and a rotor iron core. During the actual production process, after stacking multiple silicon steel sheets, they are placed in the shaping tooling, and then shaping is achieved through stamping of the shaping tooling. After stamping, the buckle points on adjacent silicon steel sheets are buckled to complete the buckling and realize the fixation between each silicon steel sheet.

[0003] The current shaping tooling for the stator iron core usually includes an upper die and a lower die. The lower die is provided with positioning columns that penetrate into the stator iron core, and then shaping and fixation are achieved by pressing down the upper die. It can be seen that currently, most use internal positioning columns to position the stator iron core. Such a shaping tooling is only suitable for conventional stator iron cores, but in the production process, some special-shaped iron cores will also be encountered, such as Figure 1 As shown, it is an air suspension iron core 1, which includes a body 2 and has teeth 3 inside and forms a slot 4 for winding. The connection between the teeth 3 and the body 2 is relatively weak. If a traditional shaping tooling is used, during the stamping process, the internal positioning columns are likely to cause the teeth 3 to deform or even the connection to break, making it difficult to apply. Summary of the Utility Model

[0004] In order to further reduce deformation and be applicable to the shaping of special-shaped iron cores, the present application provides an outer circle positioning and shaping device for an air suspension iron core.

[0005] The present application provides an outer circle positioning and shaping device for an air suspension iron core, adopting the following technical solutions:

[0006] An outer circle positioning and shaping device for an air suspension iron core includes an upper die and a lower die. The lower die is provided with vertically protruding positioning blocks, and the positioning blocks are distributed at intervals around the circumference. A positioning cavity for placing the air suspension iron core is formed inside the positioning blocks, and the inner wall of the positioning blocks is used to abut against the outer wall of the air suspension iron core. The lower die is provided with vertically arranged reinforcing strips, and the positions of the reinforcing strips correspond to the connection between the teeth and the body.

[0007] Optionally, the positioning blocks are in an arc strip shape, and the inner walls of each positioning block are arc surfaces that fit the outer wall of the air suspension iron core.

[0008] Optionally, the reinforcing strips are symmetrically arranged around the center of the lower die.

[0009] Optionally, a stripper plate is connected to the upper die. The stripper plate is provided with a first through groove for the positioning blocks to pass through, and the stripper plate is provided with a second through groove for the reinforcing strips to pass through.

[0010] Optionally, a connecting rod connected to the stripper plate is fixed on the upper mold, and a plurality of the connecting rods are evenly distributed around the circumference, and the stripper plate is vertically slidably connected to the connecting rod.

[0011] Optionally, a support portion for abutting the bottom of the stripper plate is provided on the lower die, and the connecting rod and the support portion are staggered.

[0012] Optionally, the bottom end of the connecting rod is threadedly connected to an adjusting nut, and the adjusting nut abuts against the bottom wall of the stripper plate.

[0013] Optionally, the top end of the reinforcement strip is configured in a cone shape.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. Abandoning the traditional method of using internal support columns for internal support, the air suspension core is positioned on the outer circle by means of circumferentially distributed positioning blocks. The air suspension core can be stably pressed down to complete the shaping. The positioning blocks provide external support during the downward stamping process of the upper die, effectively reducing deformation and being suitable for the shaping of special-shaped cores.

[0016] 2. Use the reinforcement strip to provide good support for the tooth connection, improve the structural strength of the part during stamping and shaping, and avoid deformation or even breakage during the stamping and shaping process;

[0017] 3. The design of the stripper plate: After the upper die completes the downward pressure shaping, the upper die moves upward and resets with the help of the stripper plate, which can drive the air suspension core to move upward to achieve automatic stripping, eliminating the need for manual stripping and effectively improving production efficiency.

[0018] 4. The position of the stripper plate can be adjusted by turning the adjusting nut, so that the stripper plate can be used for cores of various heights and specifications, thereby improving applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will further elaborate on this application in conjunction with the attached Figures 1 - 3 drawings.

[0025] An outer circle positioning and shaping device for an air suspension iron core, as Figure 2 shown in Figure 3 and

[0026] shown in Figure 2 and Figure 3 includes an upper die 5 and a lower die 6. The lower die 6 is convexly provided with positioning blocks 7. A plurality of positioning blocks 7 are evenly distributed around the circumference. The positioning blocks 7 are vertically arranged and are all arc-shaped strips. Each positioning block 7 encloses a positioning cavity 8 for placing the air suspension iron core 1. During actual use, the air suspension iron core 1 is placed in the positioning cavity 8. The inner wall of the positioning block 7 is an arc surface 9 that fits the outer wall of the air suspension iron core 1. By means of the arc surface 9 abutting against the outer wall of the air suspension iron core 1, outer circle positioning is realized, so that the air suspension iron core 1 maintains a good and stable state during the stamping and shaping process, and the air suspension iron core 1 can be stably pressed down to complete shaping. During the process of the upper die 5 moving down for stamping, the positioning blocks 7 support from the outside, effectively reducing deformation and being able to be applicable to the shaping of special-shaped iron cores.

[0027] As Figure 2 shown in Figure 3As shown, the upper mold 5 is located directly above the lower mold 6 and is lifted and lowered vertically. In actual use, the upper mold 5 can be driven to lift and lower vertically with the help of a hydraulic cylinder. A stripper plate 11 is provided on the upper mold 5, and a connecting rod 12 connected to the stripper plate 11 is vertically provided on the upper mold 5. The connecting rod 12 is vertically arranged and evenly distributed around the circumference. One end of the connecting rod 12 is fixed to the upper mold 5, and the other end passes through the stripper plate 11 and the end is threadedly connected with an adjusting nut 13. The stripper plate 11 is vertically slidably connected to the connecting rod 12, and the top of the adjusting nut 13 abuts the bottom wall of the stripper plate 11. The height of the stripper plate 11 can be adjusted by rotating the adjusting nut 13 on the connecting rod 12.

[0028] like Figure 2 and Figure 3 As shown, a first through slot 14 is vertically opened on the stripping plate 11 for the positioning block 7 to pass through, and a second through slot 15 is opened on the stripping plate 11 for the reinforcement strip 10 to pass through. The shape of the first through slot 14 is adapted to the positioning block 7, and the shape of the second slot body 4 is adapted to the reinforcement strip 10. In addition, a positioning portion 16 for abutting against the stripping plate 11 is provided on the lower mold 6, and the position of the positioning portion 16 and the connecting rod 12 are staggered to avoid interference between the positioning portion 16 and the connecting rod 12. In this way, during the downward movement of the upper mold 5, the stripping plate 11 abuts against the positioning portion 16 and the connecting rod 12 to slide relative to each other, so that the upper mold 5 continues to move downward to realize the downward pressure shaping of the air suspension core 1. After the shaping is completed, the upper mold 5 drives the stripping plate 11 to move upward during the upward movement, and the air suspension core 1 can be driven to move upward with the help of the stripping plate 11 to realize automatic stripping, without the need for manual stripping, and effectively improves production efficiency.

[0029] like Figure 2 and Figure 3 As shown, in this embodiment, the top end of the reinforcement strip 10 is configured in a cone shape, so that the reinforcement strip 10 can better enter the slot body 4 of the air suspension core 1, making it easier to place the air suspension core 1.

[0030] The working principle of the embodiment of the present application: in the initial state, the upper mold 5 is located above the lower mold 6, and the air suspension core 1 is placed in the positioning cavity 8, and then the upper mold 5 is driven to move downward. The upper mold 5 moves downward and drives the stripping plate 11 to move downward. After the stripping plate 11 abuts the positioning part 16, it slides relative to the connecting rod 12. The upper mold 5 continues to move downward until the air suspension core 1 is pressed down to complete the shaping, and then the upper mold 5 moves up and reset. During this period, the stripping plate 11 is driven upward by the connecting rod 12, and the stripping plate 11 drives the air suspension core 1 to move upward to realize automatic stripping, and the air suspension core 1 is taken out to complete the shaping process.

[0031] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
