[0055] See Figures 1 to 7 , this embodiment provides a core forming device, such as Figure 8 and Figure 9 As shown, the iron core 10 is applied to the micro-generator 100 , and the forming device includes a cutting mechanism 1 , a bending mechanism 2 and a curling mechanism 3 .

[0056] The cutting mechanism 1 is used for punching an iron sheet 20 into a formed sheet 30 . The cutting mechanism 1 comprises a support frame 11 , a punching seat 12 and a punching head 13 arranged on the support frame 11 , and a driving assembly 14 for driving the punching head 13 .

[0057] The bending mechanism 2 is used to bend the folded formed sheet 30 into a claw-grade plate 40. The bending mechanism 2 includes a rotatably connected support seat 21 and a bending assembly 22. The bending assembly 22 includes a plurality of bending plates 221 rotatably connected in sequence, and a bending gap 222 is formed between the bending plates 221 and the support seat 21.

[0058] The curling mechanism 3 includes a plurality of arc-shaped extrusion plates 31 connected and rotated in sequence. A support assembly 32 for supporting the claw-level plate 40 is provided on the relative inner side of the arc-shaped extrusion plate 31. The plurality of arc-shaped extrusion plates 31 can be surrounded to form a circular structure to extrude and surround the claw-level plate 40 to form the iron core 10.

[0059] Among them, see Figure 5 The iron sheet 20 can be cut into a forming sheet 30 under the action of the punching seat 12 and the punching head 13; the forming sheet 30 can be folded in half manually. By placing an object such as a support plate against the central axis of the forming sheet 30 and then folding the two sides of the forming sheet 30 upwards, the folding process can be easily completed; see Figure 6 When the forming sheet 30 is bent to form the claw-grade plate 40, the claw-grade side of the forming sheet 30 is clamped by the support seat 21 and the bending plate 221, and the bending plate 221 is bent toward the support seat 21 to clamp the forming sheet 30 between the bending gap 222, thereby bending the forming sheet 30 to form the claw-grade plate 40; see Figure 7When the claw-level plate 40 is curled to form the iron core 10, the claw-level plate 40 can be placed in the unfolded curling mechanism 3 and supported by the support assembly 32. When the multiple arc-shaped extrusion plates 31 are merged and folded, the inner side wall of the arc-shaped extrusion plate 31 squeezes the claw-level plate 40. Since the support assembly 32 supports the claw-level plate 40, the claw-level plate 40 can be rolled into a ring-shaped iron core 10 during the extrusion process.

[0060] This embodiment provides a core forming device, which cuts an iron sheet 20 into a formed sheet 30 through a cutting mechanism 1, bends the folded formed sheet 30 into a claw-grade plate 40 through a bending mechanism 2, and finally curls the claw-grade plate 40 into an iron core 10 through a curling mechanism 3. The bending part of the iron sheet during the forming process of the iron core 10 can be completed by workers through operating equipment, so it is simpler than pure manual processing.

[0061] Further, see Figure 2 The support frame 11 includes a first support plate 111 , a second support plate 112 , a third support plate 113 and a support plate 114 .

[0062] The second support plate 112 is located above the first support plate 111 , and a punching seat 12 is provided on the second support plate 112 .

[0063] The third support plate 113 is located above the second support plate 112 , and the punching head 13 and the driving assembly 14 are provided on the third support plate 113 .

[0064] The support plate 114 connects one side of the first support plate 111 , the second support plate 112 , and the third support plate 113 .

[0065] Among them, the first support plate 111, the second support plate 112, the third support plate 113 and the support plate 114 together form an E-shaped structure, and two columns are further arranged between the second support plate 112 and the third support plate 113 away from the support plate 114 to provide support for the punching seat 12 on the second support plate 112.

[0066] Furthermore, the punching seat 12 includes a forming hole 121 provided on the second support plate 112 , and the punching head 13 can move through the forming hole 121 .

[0067] When punching the iron sheet 20 , the iron sheet 20 can be placed on the second support plate 112 and covered above the forming hole 121 . When the punching head 13 passes through the forming hole 121 , the iron sheet 20 can be punched into the forming sheet 30 .

[0068] Furthermore,

[0069] The driving assembly 14 includes a driving motor, specifically, a high-torque output motor, so as to facilitate cutting the iron sheet 20 .

[0070] Alternatively, the driving assembly 14 includes a hydraulic rod, and the movement of the punching head 13 can be controlled by driving the hydraulic rod.

[0071] Further, see Figure 6 :

[0072] The bending plate 221 includes a first bending plate 221 a , a second bending plate 221 b and a third bending plate 221 c .

[0073] The support seat 21 is positioned relative to the first bending plate 221a, the second bending plate 221b and the third bending plate 221c to form a first supporting portion 21a, a second supporting portion 21b and a third supporting portion 21c respectively.

[0074] A clamping cavity 23 is formed between the first bending plate 221 a and the first supporting portion 21 a .

[0075] A forming cavity is formed between the first bending plate 221 a and the first supporting portion 21 a , and between the third bending plate 221 c and the third supporting portion 21 c .

[0076] Among them, when the bending plate 221 is bent and fits the support seat 21, the first bending plate 221a fits the first support part 21a, the second bending plate 221b fits the second support part 21b, and the third bending plate 221c fits the third support part 21c; first, the clamping cavity 23 between the first bending plate 221a and the first support part 21a can clamp the claw level side of the forming sheet 30, and then the forming sheet 30 is bent in turn by bending the second bending plate 221b and the third bending plate 221c. Since the claw level on the claw level plate 40 is an arc-shaped structure, the forming cavity can be an arc-shaped gap to extrude part of the structure on the forming sheet 30 into an arc shape to meet usage requirements.

[0077] Further, see Figure 6 The bending mechanism 2 further includes a locking assembly 24 , which includes a locking slot 241 , a rotating shaft 242 , a cam 243 and a control member 244 .

[0078] The locking groove 241 is provided on the first supporting portion 21 a.

[0079] The rotating shaft 242 is rotatably disposed on the first bending plate 221 a.

[0080] The cam 243 is connected to the rotating shaft 242 and can be driven by the rotating shaft 242 to rotate in the locking groove 241 .

[0081] The control member 244 is connected to the rotating shaft 242 and is used to control the rotation of the rotating shaft 242 .

[0082] Among them, an elastic structure such as a spring can be arranged between the first bending plate 221a and the first supporting part 21a to force the first bending plate 221a to move in a direction away from the first supporting part 21a, that is, to open the clamping cavity 23. The rotating shaft 242 drives the cam 243 to rotate so that the surface of the cam 243 abuts the locking groove 241 away from the side of the first supporting part 21a. When the short diameter side of the cam 243 abuts the locking groove 241, the first bending plate 221a and the first supporting part 21a are separated, the clamping cavity 23 is opened, and the side of the forming sheet 30 can be placed in; when the long diameter side of the cam 243 abuts the locking groove 241, the first bending plate 221a and the first supporting part 21a are fitted together, the clamping cavity 23 is closed, thereby clamping the side of the forming sheet 30.

[0083] Further, see Figure 7 The support assembly 32 includes a support plate 321 and a support column 322 .

[0084] The support plate 321 is disposed at the bottom of one end of the arc-shaped extrusion plate 31 .

[0085] The support column 322 is disposed at an end of the support plate 321 away from the arc-shaped extrusion plate 31 .

[0086] When placing the claw-level plate 40, the claw-level plate 40 can be supported on the support plate 321. When multiple arc-shaped extrusion plates 31 rotate and surround into a ring, the support column 322 can push the claw-level plate 40 toward the inner side wall of the arc-shaped extrusion plate 31, so that the claw-level plate 40 can be smoothly curled into a circular iron core 10.

[0087] Furthermore, handles are provided on the third bending plate 221c, the support seat 21 and the arc-shaped extrusion plate 31 to facilitate manual operation.

[0088] The control member 244 is a handle.

[0089] Working principle:

[0090] See Figure 5 The iron sheet 20 can be cut into a forming sheet 30 under the action of the punching seat 12 and the punching head 13; the forming sheet 30 can be folded in half manually. By placing an object such as a support plate against the central axis of the forming sheet 30 and then folding the two sides of the forming sheet 30 upwards, the folding process can be easily completed; see Figure 6 When the forming sheet 30 is bent to form the claw-grade plate 40, the claw-grade side of the forming sheet 30 is clamped by the support seat 21 and the bending plate 221, and the bending plate 221 is bent toward the support seat 21 to clamp the forming sheet 30 between the bending gap 222, thereby bending the forming sheet 30 to form the claw-grade plate 40; see Figure 7When the claw-level plate 40 is curled to form the iron core 10, the claw-level plate 40 can be placed in the unfolded curling mechanism 3 and supported by the support assembly 32. When the multiple arc-shaped extrusion plates 31 are merged and folded, the inner side wall of the arc-shaped extrusion plate 31 squeezes the claw-level plate 40. Since the support assembly 32 supports the claw-level plate 40, the claw-level plate 40 can be rolled into a ring-shaped iron core 10 during the extrusion process.
