Description

Technical Field

[0001] The invention relates to the technical field of shaping devices, and in particular to a motor stator punching sheet shaping device. Background Art

[0002] The motor stator consists of three parts: the stator core, the stator winding and the frame. The main function of the stator is to generate a rotating magnetic field. The stator core is an important component that constitutes the motor magnetic flux circuit and fixes the stator coil. It is formed by pressing the punching sheets and various fasteners to form a whole. The thickness of the stator core punching sheet is generally 0.5mm or 0.35mm, which is made of hot-rolled or cold-rolled silicon steel sheets or iron-nickel soft magnetic alloy sheets. The punching sheet with an outer diameter of less than 1m uses a full-circle punching sheet, and the one with an outer diameter greater than 0.99m uses a fan-shaped punching sheet. Silicon steel sheets already have certain internal stresses during the production process (such as residual stresses during cold working or annealing). During the stamping process, these internal stresses will be released or redistributed, resulting in local deformation of the material. The release of this internal stress usually causes the punching sheet to warp or bend.

[0003] The existing motor stator core punching and shaping machine (Announcement No.: CN103545992B) has at least the following disadvantages:

[0004] When the above patent is in use, the motor is started so that its output power is transmitted to the eccentric through the transmission mechanism. The eccentric shaft causes the core shaft to rotate with an eccentricity under the action of the eccentric hole, thereby shaping the stacked punching sheets and making each punching sheet neat. Since the outer surface of the stator punching sheet is evenly and evenly stamped with multiple stator slots, the above patent does not limit the stator slots during shaping, which makes the silicon steel sheet between two adjacent stator slots easily shifted during subsequent shaping, making the entire stator punching sheet scrapped.

Through this device, the stator slots on the stator punching body 6 can be sleeved on the outer surface of the top block 23. During subsequent pressure shaping, the position of the silicon steel sheet between two adjacent stator slots is limited by the top block 23, thereby ensuring that the size of the stator punching body 6 will not be offset during shaping, thereby ensuring the shaping quality of the stator punching body 6.

The bottom end of the driving wheel 28 passes through the lower surface of the mounting plate 38 and a third pulley 34 is fixedly mounted. The outer surfaces of the second pulley 33 and the third pulley 34 are sleeved with a first belt 35. A shell 8 is fixedly mounted on the lower surface of the workbench 1, and the upper surface of the shell 8 A screw rod 10 is rotatably installed on the surface, the top end of the screw rod 10 passes through the lower surface of the lifting plate 7 and is rotatably installed on the lower surface of the fixed platform 5, the screw rod 10 is threadedly connected to the lifting plate 7, a servo motor 9 is fixedly installed on the lower surface of the shell 8, the output end of the servo motor 9 passes through the upper surface of the shell 8 and is fixedly installed on the rotation center of the screw rod 10, a fourth pulley 36 is fixedly installed on the outer surface of the screw rod 10 near the bottom end, a first pulley 31 is fixedly installed on the bottom end of the rotating rod 32, and the outer surfaces of the first pulley 31 and the fourth pulley 36 are sleeved with a second belt 37.

[0036] The screw rod 10 is driven to rotate by the servo motor 9, and the screw rod 10 drives the lifting plate 7 to move up, and the lifting plate 7 drives multiple top blocks 23 to move up. The fourth pulley 36 is driven to rotate by the rotation of the screw rod 10, and the fourth pulley 36 drives the first pulley 31 to rotate through the second belt 37. The first pulley 31 drives the second pulley 33 to rotate through the rotating rod 32, and the second pulley 33 drives the third pulley 34 to rotate through the first belt 35. The third pulley 34 drives the driving wheel 28 to rotate, and the driving wheel 28 drives the transmission shaft 27 to rotate back and forth through the driving column 30, the driving groove 29 and the swing rod 39. The transmission shaft 27 drives the rotating wheel 22 to rotate back and forth through the second gear and the first gear 26. The rotating wheel 22 intermittently reciprocates with the stator punch body 6 through the rubber convex strips on the surface, thereby driving the stator punch body 6 to rotate back and forth in a small amplitude. Through this device, the stator slot on the stator punch body 6 can be sleeved on the outer surface of the top block 23. During the subsequent pressure shaping, the position of the silicon steel sheet between two adjacent stator slots is limited by the top block 23.

[0037] In this embodiment, a compression cylinder 11 is fixedly installed on the lower surface of the shell 8, the top end of the compression cylinder 11 passes through the upper surface of the shell 8, a piston plate 14 is slidably installed on the inner wall of the compression cylinder 11, a connecting rod 13 is fixedly installed on the upper surface of the middle position of the piston plate 14, the top end of the connecting rod 13 is fixedly installed with the lower surface of the lifting plate 7, a circular hole is penetrated through the lower surface of the compression cylinder 11, a fixed block 18 is fixedly installed on the inner wall of the circular hole, a plurality of exhaust holes are penetrated through the outer surface of the fixed block 18, a sliding column 16 is slidably inserted on the upper surface of the fixed block 18, and the bottom end of the sliding column 16 passes through the lower surface of the fixed block 18 and is fixedly installed There is a bottom plate 1401, a sealing plate 15 is fixedly installed on the top of the sliding column 16, the diameter of the sealing plate 15 is larger than the diameter of the fixed block 18, a spring 17 is sleeved on the outer surface of the sliding column 16, and the spring 17 is arranged between the fixed block 18 and the bottom plate 1401, a plurality of air holes 19 are equidistantly provided in the circumferential direction of the upper surface of the fixed platform 5, a flow channel is arranged inside the fixed platform 5, and the plurality of air holes 19 are connected to the flow channel, an air pipe 12 is fixedly connected to the outer surface of the compression cylinder 11 near the bottom end, the other end of the air pipe 12 passes through the outer surface of the fixed platform 5 and is connected to the flow channel, and the flow channel is connected to the compression cylinder 11 through the air pipe 12.

[0038] When the position of the stator punch body 6 is correctly limited, its lower surface will be flush with the upper surface of the fixed platform 5. At this time, the air hole 19 is blocked and air cannot be inhaled. Due to the negative pressure inside the compression cylinder 11, the sealing plate 15 will move up. As air enters the interior of the compression cylinder 11, the sealing plate 15 is driven by the force of the spring 17 to fit the fixed block 18 to seal the compression cylinder 11 again. When the sealing plate 15 fits the fixed block 18, the sealing plate 15 will knock on the surface of the fixed block 18 and make a sound. This device can remind the operator whether the position of the stator punch body 6 is correctly limited. On the contrary, the operator can confirm again whether the position of the stator punch body 6 is correctly limited to avoid damage to the stator punch body 6 during subsequent shaping.

[0039] In this embodiment, it should be noted that the reciprocating distance of the rotating wheel 22 is smaller than the distance between two adjacent stator slots, so as to avoid excessive rotation of the stator punch body 6 caused by the rotating wheel 22 and facilitate the alignment of the stator slots on the stator punch body 6 with the top block 23.

[0040] It should be noted that when the present invention is used, the operator places the stator punch body 6 on the upper surface of the fixing table 5, and places the stator punch body 6 in the middle of the fixing table 5 through the hole between the positioning boss and the stator punch body 6;

[0041] The servo motor 9 drives the screw rod 10 to rotate, the screw rod 10 drives the lifting plate 7 to move up, the lifting plate 7 drives multiple top blocks 23 to move up, the lifting plate 7 starts to move up, and the spiral groove of the guide column 25 and the guide groove 24 drives the rotating shaft 20 to rotate. The rotating shaft 20 drives the rotating wheel 22 to move close to the stator punch body 6 through the fixed rod 21, so that the rubber convex strip on its outer surface is against the circumferential outer surface of the stator punch body 6. When the guide column 25 moves to the straight groove position of the guide groove 24, the position of the rotating wheel 22 remains unchanged. At this time, the lifting plate 7 continues to move up. At the same time, the fourth pulley 36 is driven to rotate by the rotation of the screw rod 10. The fourth pulley 36 drives the first pulley 31 to rotate through the second belt 37. The first pulley 31 drives the second pulley 33 to rotate through the rotating rod 32. The third pulley 34 is driven to rotate by the first belt 35, and the third pulley 34 drives the driving wheel 28 to rotate.

The transmission shaft 27 drives the rotating wheel 22 to rotate back and forth through the second gear and the first gear 26. The rotating wheel 22 intermittently reciprocates with the stator punch body 6 through the rubber convex strips on the surface, thereby driving the stator punch body 6 to rotate back and forth in a small amplitude. Through this device, the stator slots on the stator punch body 6 can be sleeved on the outer surface of the top block 23. During the subsequent pressure shaping, the top block 23 limits the position of the silicon steel sheet between two adjacent stator slots, thereby ensuring that the size of the stator punch body 6 will not be offset during shaping, and ensuring the shaping quality of the stator punch body 6;

[0042] By moving the lifting plate 7 upward, it drives the piston plate 14 upward by driving the connecting rod 13, so that negative pressure is formed inside the compression cylinder 11, and air is sucked through the air hole 19 through the air pipe 12 and the flow channel. The position of the stator punch body 6 is easily limited by this device. At the same time, when the position of the stator punch body 6 is correctly limited, its lower surface will be flush with the upper surface of the fixed platform 5. At this time, the air hole 19 is blocked and cannot be inhaled. Due to the negative pressure inside the compression cylinder 11, the sealing plate 15 moves up. As air enters the interior of the compression cylinder 11, the sealing plate 15 is driven by the force of the spring 17 to fit the fixed block 18 to seal the compression cylinder 11 again. When the sealing plate 15 fits the fixed block 18, the sealing plate 15 will knock on the surface of the fixed block 18 to make a sound. The present device can remind the operator whether the position of the stator punch body 6 is correctly limited. On the contrary, the operator can confirm again whether the position of the stator punch body 6 is correctly limited to avoid damage to the stator punch body 6 during subsequent shaping.

[0043] When the position of the stator punch body 6 is correctly limited, the shaping press head 4 is driven downward by the downward movement of the telescopic end of the hydraulic telescopic rod 3 , so that the shaping press head 4 presses down and shapes the stator punch body 6 .

[0044] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
