Description

Technical Field

[0001] This utility model belongs to the field of motor waste treatment technology, and specifically relates to a waste punching and shearing device for motor spring sheets. Background Technology

[0002] The main components of a stepper motor include the stator, rotor, bearings, housing, cables, and drive circuitry. The stator and rotor are typically made of high-quality silicon steel sheets and magnetic materials, which undergo precision machining and inspection to ensure their magnetic and electrical properties meet requirements. The production and processing of stepper motors generates a significant amount of waste material. Directly discarding this waste would be resource-intensive; therefore, the material is usually cut and then reprocessed.

[0003] In existing punching and shearing devices, the lower blade is fitted into the punching and shearing hole. When replacing the lower blade, it is not easy for the disassembly tool to reach into the gap between the lower blade and the punching and shearing hole, making the replacement extremely inconvenient. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned technology and provide a waste shearing device for motor spring sheets.

[0005] Therefore, this utility model provides a scrap punching and shearing device for motor spring sheets, including a support plate with punching and shearing holes. The punching and shearing holes are T-shaped, with the transverse groove of the punching and shearing hole being a blind hole and the longitudinal groove being a through hole. A lower blade is connected to the blind hole through a mounting hole. The side of the lower blade near the longitudinal groove has a gap, while the side away from the longitudinal groove is adapted to fill the interior of the transverse groove. The through hole of the longitudinal groove extends into the transverse groove and extends to the bottom of the lower blade.

[0006] Furthermore, a vertical plate is fixedly connected to the support plate, and a downward pressure cylinder is fixedly connected to the side of the vertical plate. The downward pressure cylinder provides an output stroke in the vertical direction. A positioning plate is fixedly connected to the output shaft of the downward pressure cylinder. An installation groove is provided on the positioning plate, and an upper punch is installed in the installation groove.

[0007] Furthermore, the side wall of the upper punch away from the vertical plate and the side wall of the lower blade close to the vertical plate are on the same plane, so that the upper punch and the lower blade form a scissor structure to punch and shear the waste material.

[0008] Furthermore, in the direction of the longitudinal groove of the punching and shearing hole, an extension plate is also provided on the support plate, and pressure blocks are symmetrically installed on the extension plate about the center line, with waste material pressed between the two symmetrical pressure blocks.

[0009] Furthermore, a funnel is fixedly connected to the support plate below the punching and shearing hole. The funnel completely encloses the punching and shearing hole to prevent waste material from splashing during shearing.

[0010] Furthermore, above the punching and shearing hole, a baffle is fixedly connected to the support plate. The baffle has a knife groove, the shape of which matches the shape of the upper punch. The side wall of the baffle away from the vertical plate and the side wall of the lower blade close to the vertical plate are on the same plane. When cutting the waste, the baffle and the upper punch cooperate to fill and completely seal the gap between the lower blade and the longitudinal groove of the punching and shearing hole.

[0011] This utility model provides a waste shearing device for motor spring sheets, which has the following beneficial effects:

[0012] By setting a gap on one side of the longitudinal groove near the punching and shearing hole of the lower blade, and fitting the other side into the transverse groove; the through hole of the longitudinal groove extends into the transverse groove, extending to the bottom of the lower blade; after the reserved gap, when replacing the lower blade, the disassembly tool can pass through the gap and extend to the bottom of the lower blade, prying the lower blade out of the punching and shearing hole, making the replacement of the lower blade more convenient.

[0013] By setting a funnel to completely enclose the punching and shearing hole, and ensuring that the side wall of the baffle away from the vertical plate and the side wall of the lower blade near the vertical plate are on the same plane, the punching and shearing hole is sealed in both the upper and lower directions, effectively preventing waste material from splashing during shearing.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0019] like Figure 1As shown, this utility model provides a waste punching and shearing device for motor spring sheets, including a base plate 1, which is rectangular. The four corners of the rectangle are fixedly connected to support columns 2 through mounting holes. The top of the support columns 2 is fixedly connected to a bracket plate 3, which is also rectangular. The support columns 2 are also fixedly connected to the four corners of the bracket plate 3 through mounting holes. By placing the support columns 2 at the corners, the pressure on the base plate 1 and the bracket plate 3 is uniform, and the overall structure has high strength.

[0020] A vertical plate 5 is fixedly connected to the midpoint of the two long rectangular sides of the support plate 3. The vertical plate 5 is perpendicular to the support plate 3, and its width is the same as the width of the short side of the support plate 3. A downward pressing cylinder 7 is fixedly connected to the top side of the vertical plate 5, providing the output stroke in the vertical direction. A positioning plate 8 is fixedly connected to the output shaft of the downward pressing cylinder 7. The positioning plate 8 is rectangular and horizontally positioned. Figure 2 As shown, the long rectangular side of the positioning plate 8 is parallel to the upright plate 5. A mounting groove 6 is provided on the long rectangular side of the positioning plate 8 away from the upright plate 5. An upper punch 10 is fixedly connected in the mounting groove 6. Only the upper half of the upper punch 10 is located in the mounting groove 6. The shape of the mounting groove 6 matches the shape of the upper punch 10. The upper punch 10 is cuboid, and its longest side is in the vertical direction.

[0021] like Figure 3 As shown, a shearing hole 11 is provided on the support plate 3 below the upper punch 10. The shearing hole 11 is T-shaped, with a blind slot 17 in the transverse groove 17 and a through slot 18 in the longitudinal groove 18. A lower blade 12 is fixedly connected to the blind hole through a mounting hole. The side wall of the upper punch 10 away from the vertical plate 5 and the side wall of the lower blade 12 near the vertical plate 5 are on the same plane, forming a scissor structure to shear the waste material 15. In the direction extending from the longitudinal groove 18 of the shearing hole 11, an extension plate 4 is also provided on the support plate 3. The center line of the extension plate 4 coincides with the center line of the longitudinal groove 18 of the shearing hole 11. Two sets of pressure blocks 14 are symmetrically installed on the extension plate 4 about the center line, and the waste material 15 is pressed between the two symmetrical pressure blocks 14. Through the above arrangement, it is ensured that the waste material 15 placed on the extension plate 4 can be conveyed into the longitudinal groove 18 of the shearing hole 11 to complete the shearing action.

[0022] In use, first place the scrap 15 on the center line of the extension plate 4, then install the pressure block 14 on the extension plate 4 to horizontally limit and vertically press the scrap 15. Push the scrap 15 into the longitudinal groove 18 of the punching and shearing hole 11, and the output shaft of the pressing cylinder 7 moves downward, so that the upper punch 10 and the lower blade 12 cooperate to cut the scrap 15; then the output shaft of the pressing cylinder 7 moves upward, so that the upper punch 10 and the lower blade 12 separate, and continue to push the scrap 15. Repeat the above operation until the punching and shearing of the scrap 15 is completed.

[0023] Below the punching and shearing hole 11, a funnel 13 is fixedly connected to the bottom surface of the support plate 3, and the funnel 13 passes through the bottom plate 1; the cut waste material 15 is guided by the funnel 13 and falls into the collection box below the funnel 13. The funnel 13 completely encloses the punching and shearing hole 11 to prevent the waste material 15 from splashing during shearing. On the opposite side of the vertical plate 5 where the pressing cylinder 7 is installed, a reinforcing plate 16 is fixedly connected to both ends of the vertical plate 5. The reinforcing plate 16 is a right-angled trapezoid, with its bottom edge connected to the vertical plate 5 and its right-angled side connected to the support plate 3, thereby improving the overall structural strength of the vertical plate 5.

[0024] like Figure 3 As shown, the lower blade 12 has a gap on one side of the longitudinal groove 18 near the punching and shearing hole 11, and the other side is adapted to fill the interior of the transverse groove 17; the through hole of the longitudinal groove 18 extends into the transverse groove 17 and extends to the lower blade 12; after the gap is reserved, when replacing the lower blade 12, the disassembly tool can pass through the gap and extend to the lower blade 12 to pry the lower blade 12 out of the punching and shearing hole 11.

[0025] like Figure 2 As shown, a baffle 9 is fixedly connected to the top surface of the support plate 3 above the punching hole 11. A knife groove 19 is provided on the baffle 9. The side of the knife groove 19 is an open end and its shape is adapted to the shape of the upper punch 10. The side wall of the baffle 9 away from the vertical plate 5 and the side wall of the lower blade 12 near the vertical plate 5 are located on the same plane. The above arrangement can fill the gap between the lower blade 12 and the longitudinal groove 18 of the punching hole 11 when shearing the waste material 15, by the cooperation of the baffle 9 and the upper punch 10, and prevent the waste material 15 from splashing.
