Detailed implementation mode

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Example 1, please refer to Figures 1-9, the present invention provides the following technical solution: A punching die for soft magnetic materials, comprising a die assembly 1; the die assembly 1 includes a base 101, a rotating shaft 102 is rotatably connected to the top of the base 101, a lower template 103 is rotatably connected to the top of the rotating shaft 102, and a first cylindrical groove 104 and a second cylindrical groove 105 are provided at 120° on the top of the lower template 103; a groove 106 is provided at the bottom of the lower template 103, and two arc-shaped convex blocks 107 are fixedly connected to the inner circumferential surface of the groove 106. Two notches are provided on the circumferential surface of the rotating shaft 102, and a resisting rod 108 that abuts against the arc-shaped convex block 107 is slidably connected inside the notches. A return spring 109 is fixedly connected between the resisting rod 108 and the notches. A notch 124 is provided through the top of the lower template 103, and a baffle 125 that abuts against the notch 124 is fixedly connected to the top of the base 101; a punching die assembly 2 is fixedly fitted to the top of the base 101. The punching die assembly 2 includes a first L-shaped plate 201 fixedly connected to the top of the base 101, a mounting plate 202 is fixedly connected to the end of the first L-shaped plate 201, a lead screw 203 is rotatably connected through the top of the mounting plate 202, a lifting plate 204 is threadedly connected to the circumferential surface of the lead screw 203, an extension rod 205 is fixedly connected to the bottom of the lifting plate 204, a punching plate 206 is fixedly connected to the bottom of the extension rod 205, and a first straight gear 207 is fixedly connected to the top of the lead screw 203.

[0031] The operation process of this embodiment is as follows: First, the soft magnetic materials are respectively placed into the first cylindrical groove 104 and the second cylindrical groove 105. Subsequently, the rotating shaft 102 is controlled to rotate, thereby driving the two resisting rods 108 on the rotating shaft 102 to rotate, so that the two resisting rods 108 respectively abut against the two arc-shaped convex blocks 107, and then the lower template 103 is driven to rotate by the arc-shaped convex blocks 107, so that the lower template 103 rotates to abut against the baffle 125 (as Figure 1 shown in the state, the punching plate 206 is located inside the first cylindrical groove 104). During the process of the lower template 103 rotating towards the baffle 125, synchronously control the first straight gear 207 to rotate, so that the first straight gear 207 drives the lead screw 203 to rotate, and the lead screw 203 drives the lifting plate 204 to move downward. Then, the lifting plate 204 drives the punching plate 206 to move downward through the extension rod 205. When the lower template 103 rotates to abut against the baffle 125, at this time, the punching plate 206 just moves downward to the inside of the first cylindrical groove 104. Subsequently, continue to control the rotating shaft 102 to rotate. Blocked by the baffle 125, the lower template 103 cannot continue to rotate. However, driven by the rotating shaft 102, the resisting rod 108 compresses the return spring 109 and moves into the notch, so that the resisting rod 108 crosses the arc-shaped convex block 107, thereby ensuring that the first straight gear 207 continues to rotate, and then driving the punching plate 206 to continue to move downward along the first cylindrical groove 104, thereby realizing the punching of the soft magnetic material;

[0032] After the soft magnetic material inside the first cylindrical groove 104 is stamped, control the rotating rod 102 to rotate in the reverse direction. At this time, the stamping plate 206 is located inside the first cylindrical groove 104, making the lower template 103 unable to rotate. However, the abutting rod 108 on the rotating shaft 102 can cross over the arc-shaped bump 107, thus ensuring the normal reverse rotation of the rotating shaft 102. Synchronously control the first spur gear 207 to rotate in the reverse direction, and then drive the stamping plate 206 to move upward through the lifting plate 204, so that the stamping plate 206 is disengaged from the contact with the first cylindrical groove 104. Then, through the reverse rotation of the rotating shaft 102, the rotating shaft 102 further drives the lower template 103 to rotate in the reverse direction, so that the lower template 103 rotates to contact the baffle 125. At this time, the second cylindrical groove 105 is concentric with the stamping plate 206. During the process of the lower template 103 rotating in the reverse direction to contact the baffle 125, the stamping plate 206 first disengages from the contact with the lower template 103, and then control the first spur gear 207 to rotate in the forward direction. When the lower template 103 rotates in the reverse direction to contact the baffle 125, at this time, through the forward rotation of the first spur gear 207, the lifting plate 204 drives the stamping plate 206 to just move into the second cylindrical groove 105. Then continue to control the rotating rod 102 to rotate in the reverse direction. Under the obstruction of the baffle 125, the lower template 103 stops rotating, and synchronously makes the stamping plate 206 continue to move downward, so as to realize the stamping of the soft magnetic material inside the second cylindrical groove 105;

[0033] By using this device, when the soft magnetic material is stamped in the first cylindrical groove 104, the second cylindrical groove 105 can be demolded and loaded, or when the soft magnetic material is stamped in the second cylindrical groove 105, the first cylindrical groove 104 can be demolded and loaded, thereby improving the continuity of the stamping of the soft magnetic material and further improving the production efficiency.

[0034] Example two, please refer to Figures 1-9, the second embodiment is improved on the basis of the first embodiment as follows: the mold assembly 1 also includes a control box 110 fixedly connected to the top of the base 101, a motor 111 is fixedly connected to the top of the base 101, a rotating rod 112 is fixedly connected to the output end of the motor 111, a first sprocket 113 and a first pulley 114 are fixedly connected to the side of the rotating rod 112 in sequence, a first bevel gear 115 is fixedly connected to the top of the rotating rod 112, a second sprocket 116 is fixedly connected to the side of the rotating shaft 102, a chain is meshed between the first sprocket 113 and the second sprocket 116, and the top of the base 101 is fixedly connected to the lifting plate 2 04 A first guide rod 117 is slidably matched, and a second threaded rod 118 is rotatably connected to the top of the base 101, and a second pulley 119 is fixedly connected to the side surface of the second threaded rod 118, and a belt is arranged for transmission between the second pulley 119 and the first pulley 114, and a second guide rod 120 is fixedly connected to the top of the base 101, and an arc groove 121 is provided at the bottom of the lower template 103, and a support rod 122 is fixedly connected to the top of the base 101, and an arc plate 123 is fixedly connected to the top of the support rod 122, and the arc plate 123 is slidably matched with the arc groove 121, and a notch 124 is provided through the top of the lower template 103.

[0035] The operation process of this embodiment is: by controlling the motor 111 to drive the rotating rod 112 to rotate, the rotating rod 112 synchronously drives the first sprocket 113, the first pulley 114 and the first bevel gear 115 to rotate, so that the first sprocket 113 drives the second sprocket 116 to rotate through the chain, and then drives the rotating shaft 102 to rotate, providing power for the rotation of the rotating shaft 102. At the same time, the first pulley 114 drives the second pulley 119 to rotate through the belt, and the second pulley 119 drives the second threaded rod 118 to rotate, providing power for the rotation of the second threaded rod 118. By setting the support rod 122 and the arc plate 123, the arc plate 123 provides support for the lower template 103 during the stamping process of the magnetic material, thereby improving the stability of the lower template 103.

[0036] For example 3, please refer to Figures 1-9, in the third embodiment, the following improvements are made on the basis of the first embodiment. The punching die assembly 2 further includes a U-shaped plate 208 slidably connected to the top of the mounting plate 202. A first rotating rod 209 and a second rotating rod 210 are rotatably connected to the top of the U-shaped plate 208 and are located outside the lead screw 203. Fixedly connected to the tops of the first rotating rod 209 and the second rotating rod 210 are second spur gears 211 that mesh with the first spur gear 207. Fixedly connected to the circumferential sides of the first rotating rod 209 and the second rotating rod 210 are worm wheels 212. Fixedly connected to the top of the U-shaped plate 208 is a first vertical plate 213. Rotatably connected through one side surface of the first vertical plate 213 is a bidirectional worm 214 that meshes with the two worm wheels 212. Fixedly connected to the top of the mounting plate 202 is an electric push rod 215, and the electric push rod 215 is fixedly fitted with the U-shaped plate 208. Fixedly connected to the top of the mounting plate 202 is a second vertical plate 216. Rotatably connected through one side surface of the second vertical plate 216 is a cylindrical tube 217. Symmetrically provided on the inner circumferential side of the cylindrical tube 217 are sliding grooves 218. Symmetrically fixedly connected to the circumferential side of the bidirectional worm 214 are sliding rods 219 that are slidably fitted with the two sliding grooves 218. Fixedly connected to one end of the cylindrical tube 217 is a second bevel gear 220, and the second bevel gear 220 meshes with the first bevel gear 115.

[0037] The operation process of this embodiment is as follows: By rotating the first bevel gear 115, the first bevel gear 115 drives the second bevel gear 220 meshing with it to rotate, and then drives the cylindrical tube 217 to rotate. Through the cooperation of the sliding grooves 218 of the cylindrical tube 217 and the two sliding rods 218, the bidirectional worm 214 is further driven to rotate (the threads on the outer wall of the bidirectional worm 214 are arranged in opposite directions), so that the bidirectional worm 214 further meshes to drive the two worm wheels 212 to rotate synchronously, and then the rotation directions of the two worm wheels 212 are opposite. Thus, the two worm wheels 212 further drive the two second spur gears 211 to rotate in opposite directions. Then, by controlling the electric push rod 215 to drive the U-shaped plate 208 to move away from or close to the second vertical plate 216, one of the second spur gears 211 is meshed with the first spur gear 207, thereby providing power for the first spur gear 207 to rotate forward or backward.

[0038] Embodiment Four, please refer to Figures 1-9 , in the fourth embodiment, the following improvements are made on the basis of the first embodiment. A demoulding component 3 is threadedly fitted on the circumferential side of the second threaded rod 118. The demoulding component 3 includes a second L-shaped plate 301 threadedly connected to the circumferential side of the second threaded rod 118. Fixedly connected to the end of the second L-shaped plate 301 is a cross plate 302. Fixedly connected to the bottom of the cross plate 302 is an electromagnet 303 adapted to the first cylindrical groove 104 and the second cylindrical groove 105. The second L-shaped plate 301 is slidably fitted with the second guide rod 120. A PLC controller is provided inside the control box 110, and the PLC controller is electrically connected to the motor 111, the electric push rod 215, and the electromagnet 303.

[0039] The operation process of this embodiment is as follows: By rotating the second threaded rod 118, the second threaded rod 118 drives the second L-shaped plate 301 to move in the vertical direction. Further, the second L-shaped plate 301 drives the electromagnet 303 to move in the vertical direction through the cross plate 302. When the electromagnet 303 moves downward, it gets close to the soft magnetic material after stamping. Then, the electromagnet 303 is powered on, so as to adsorb the soft magnetic material after stamping, and further realize the rapid demolding of the soft magnetic material after stamping.
