Description

Technical Field

[0001] This utility model relates to the field of metal processing machinery manufacturing technology, specifically to a motorcycle iron core stamping and forming processing device. Background Technology

[0002] As an important means of transportation and leisure, the performance of the core power component of a motorcycle—the motor (such as the starter motor and drive motor)—is crucial. The motor core (stator core and rotor core) is the core magnetic conductor of the motor, and its manufacturing precision, consistency, and production efficiency directly affect the motor's performance, efficiency, and cost. Currently, motorcycle cores are mainly formed from high-grade silicon steel sheets through precision stamping processes. In the stamping process of motorcycle cores, multi-station progressive dies are commonly used for production on high-speed stamping presses. The existing technology has the following problems:

[0003] Because motorcycle cores typically have complex geometries (such as multi-pole shoes, special grooves, and overlapping riveting points), and products are updated and replaced quickly, production lines are required to have high flexibility. However, the installation, debugging, and replacement of molds in traditional stamping equipment are cumbersome and time-consuming. Especially for multi-station progressive dies that require high-precision positioning, mold changeover time is often long, which seriously restricts production efficiency and the ability to handle multi-variety, small-batch orders. At the same time, if the fine iron filings generated during the stamping process of existing stamping equipment are not collected and treated in a timely and effective manner, they will not only contaminate the equipment and molds, affecting the feeding accuracy and mold life, but may also be carried into the lamination room, affecting the electrical insulation performance of the core, and increasing the cleaning and maintenance costs of the workshop.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2As shown, this utility model provides a stamping and forming processing device for motorcycle iron cores, including a stamping machine housing 1. A die pressing mechanism 2 and a die fixing mechanism 3 are arranged inside the stamping machine housing 1. The die pressing mechanism 2 is located above the die fixing mechanism 3. The die pressing mechanism 2 includes a pressing box 21, which is driven by a hydraulic system. T-shaped through slots 22 are formed on both the left and right sides of the bottom of the pressing box 21. T-shaped sliding plates 23 are slidably installed on the inner sides of the two T-shaped through slots 22. An upper die mounting plate 24 is fixedly installed at the bottom of the two T-shaped sliding plates 23. A limiting mounting plate 26 is fixedly installed on the front side of the opposite front of the two T-shaped sliding plates 23. The limiting mounting plate 26 includes several fixing bolts 27. The limiting mounting plate 26 is fixedly installed on the front side of the pressing box 21 using several fixing bolts 27. The die fixing mechanism 3 includes a fixing base 31. The top left and right sides of the fixed base 31 are provided with T-shaped through slots 32 that run from front to back. T-shaped slide plates 33 are slidably installed on the inner sides of the two T-shaped through slots 32. The top of the two T-shaped slide plates 33 is fixedly installed with a lower mold mounting plate 34. The front of the opposite front of the two T-shaped slide plates 33 is fixedly installed with a limiting mounting plate 36. The limiting mounting plate 36 includes several fixing bolts 37. The limiting mounting plate 36 is fixedly installed on the front of the fixed base 31 by several fixing bolts 37. The bottom of the upper mold mounting plate 24 is provided with several positioning T-shaped slots 25 that run from front to back. The top of the lower mold mounting plate 34 is provided with several positioning T-shaped slots 35 that run from front to back. The bottom of the upper mold mounting plate 24 is fixedly installed with the upper mold by several positioning T-shaped slots 25. The top of the lower mold mounting plate 34 is fixedly installed with the lower mold by several positioning T-shaped slots 35.

[0024] In use, the upper and lower dies are first fixedly mounted on the bottom of the upper die mounting plate 24 and the top of the lower die mounting plate 34 via the positioning T-slot 25 at the bottom of the upper die mounting plate 24 and the positioning T-slot 35 at the top of the lower die mounting plate 34. At the same time, the upper die mounting plate 24 is fixed to the bottom of the lower pressure box 21 by the limiting mounting plate 26 between the two T-slide plates 23 and the fixing bolt 27. The lower die mounting plate 34 is fixed to the top of the fixed base 31 by the limiting mounting plate 36 between the two T-slide plates 33 and the fixing bolt 37. The lower pressure box 21 is driven to descend by the hydraulic rod of the stamping machine, thereby merging the upper and lower dies and completing the stamping of the motorcycle iron core parts.

[0025] like Figure 3As shown, an extension mold mounting plate 241 is fixedly mounted on the rear side of the upper mold mounting plate 24. Extension T-shaped sliding plates 242 are fixedly mounted on the top left and right sides of the extension mold mounting plate 241. The two extension T-shaped sliding plates 242 are fixedly connected to two T-shaped sliding plates 23 and slidably connected to the T-shaped through groove 22, respectively. A limiting mounting plate 243 is fixedly mounted on the rear side of the opposite surfaces of the two extension T-shaped sliding plates 242. The limiting mounting plate 243 includes several fixing bolts 244. The limiting mounting plate 243 is fixedly mounted on the rear side of the lower pressure box 21 using these fixing bolts. An extension mold mounting plate is fixedly mounted on the rear end of the lower mold mounting plate 34. Two extended T-shaped sliding plates 342 are fixedly installed at the bottom of the extended mold mounting plate 341. The two extended T-shaped sliding plates 342 are fixedly connected to two T-shaped sliding plates 33 and slidably connected to the T-shaped through groove 32. A limiting mounting plate 343 is fixedly installed on the rear side of the opposite face of the two extended T-shaped sliding plates 342. The limiting mounting plate 343 includes several fixing bolts 344. The limiting mounting plate 343 is fixedly installed on the rear side of the fixed base 31 by several fixing bolts 344. Square insert rings 345 are fixedly installed on both the left and right ends of the extended mold mounting plate 341 and the lower mold mounting plate 34 near the limiting mounting plate 343.

[0026] When installing the upper and lower dies at the bottom of the upper die mounting plate 24 and the top of the lower die mounting plate 34, another set of upper and lower dies for different stamping parts can also be fixedly installed at the bottom of the extension die mounting plate 1 241 and the top of the extension die mounting plate 2 341 using the grooves at the bottom and top of the extension die mounting plate 2 341. When the upper die mounting plate 24 and the lower die mounting plate 34 are combined, the extension die mounting plate 1 241 and the extension die mounting plate 2 341 will also be combined. However, at this time, no stamping material needs to be placed in the die between the extension die mounting plate 1 241 and the extension die mounting plate 2 341. Once the stamping parts need to be replaced, the fixed limit mounting plate 1 26 and the limit mounting plate can be disassembled. The fixing bolts 27 and 37 of the second 36 simultaneously push the extension mold mounting plate 241 and the extension mold mounting plate 341 forward until the limiting mounting plate 3243 abuts against the rear side of the pressure box 21 and the limiting mounting plate 4343 abuts against the rear side of the fixed base 31. During sliding, the extension T-shaped sliding plate 242 and the extension T-shaped sliding plate 23 slide in the T-shaped through groove 22 and the extension T-shaped sliding plate 342 and the extension T-shaped sliding plate 33 slide in the T-shaped through groove 32 maintain the stability of movement. Finally, the limiting mounting plate 3243 is fixed to the pressure box 21 and the limiting mounting plate 4343 is fixed to the fixed base 31 by fixing the fixing bolts 244 and 344 respectively. This completes the rapid conversion of different stamping part molds.

[0027] like Figure 4 , Figure 5 As shown, lifting slots 11 are provided on both the front and rear sides of the bottom of the inner wall of the stamping machine housing 1. Two electric push rods 12 are fixedly installed on the right side of the inner wall of the stamping machine housing 1. A chip blowing box 13 is fixedly installed at the output end of each of the two electric push rods 12. The two chip blowing boxes 13 are respectively engaged with the two lifting slots 11. A filter screen plate 131 is fixedly installed on the side of the inner wall of the two chip blowing boxes 13 away from the mold fixing mechanism 3. A connecting plate 132 is fixedly installed between the left and right sides of the inner wall of the two chip blowing boxes 13. Several exhaust fans are evenly fixedly installed on the side of the connecting plate 132 away from the filter screen plate 131. Fan 133, the inner sides of the two square insertion rings 345 on the left and right are each snapped with a rod 14, and L-shaped extension plates 141 are fixedly installed on the rear side of the two rods 14. A mesh bag 142 is fixedly installed on the rear side of the vertical part of the two L-shaped extension plates 141. The mesh bag 142 is located on the rear side of the extension mold mounting plate 2 341. The height of the mesh bag 142 is the same as the separation height of the upper and lower molds. An inclined guide plate 143 is fixedly installed on the side of the two rods 14 away from the extension mold mounting plate 2 341. The opposite ends of the two inclined guide plates 143 are aligned with the left and right sides of the inner wall of the stamping machine housing 1, respectively.

[0028] When the upper mold mounting plate 24 and the lower mold mounting plate 34 are not pushed forward, the front electric push rod 12 can be activated after the stamping is completed to drive the chip blowing box 13 in the front lifting groove 11 to rise. This simultaneously activates the exhaust fan 133 on the outer wall of the connecting plate 132 inside the front chip blowing box 13, thereby blowing external air through the filter screen 131 and blowing it into the mold between the upper mold mounting plate 24 and the lower mold mounting plate 34, blowing the debris backward until it is blown into the mesh bag 142. Similarly, when the extension mold mounting plate 11 241 and the extension mold mounting plate 242 34 are not pushed forward, the exhaust fan 133 on the outer wall of the connecting plate 132 inside the front chip blowing box 13 will be activated. When 41 is between the pressure box 21 and the fixed base 31, the rear electric push rod 12 can be driven to control the rear chip blowing box 13 to rise. The front chip blowing box 13 is in the inner cavity of the lifting groove 11. The mesh bag 142 can catch the debris blown forward by the rear chip blowing box 13 by pulling out the two insert rods 14 inserted into the rear square insert rings 345 and inserting them into the two front square insert rings 345. At the same time, when blowing, the inclined guide plate 143 on one side of the two insert rods 14 can prevent the debris between the molds from being blown out from both sides, thus playing a guiding role.

[0029] The working principle of the motorcycle core stamping and forming processing device will be explained in detail below.

[0030] like Figure 1-5As shown, in use, one set of upper and lower dies is first fixedly installed on the bottom of the upper die mounting plate 24 and the top of the lower die mounting plate 34 via the positioning T-slot 25 at the bottom of the upper die mounting plate 24 and the positioning T-slot 35 at the top of the lower die mounting plate 34. Simultaneously, the upper die mounting plate 24 is fixed to the bottom of the lower pressure box 21 using the limiting mounting plate 26 between the two T-slide plates 23 and the fixing bolt 27. The lower die mounting plate 34 is fixed to the top of the fixed base 31 using the limiting mounting plate 36 between the two T-slide plates 33 and the fixing bolt 37. The lower pressure box 21 is then driven to descend by the hydraulic rod of the stamping press, merging the upper and lower dies to complete the stamping forming of the motorcycle core parts. Simultaneously, when installing the upper and lower dies at the bottom of the upper die mounting plate 24 and the top of the lower die mounting plate 34, another set of upper and lower dies for different stamping parts can also be fixedly installed at the bottom of the extension die mounting plate 1 241 and the top of the extension die mounting plate 2 341 using the grooves at the bottom and top of the extension die mounting plate 2 341. When the upper die mounting plate 24 and the lower die mounting plate 34 are merged, the extension die mounting plate 1 241 and the extension die mounting plate 2 341 will also be merged. However, at this time, no stamping material needs to be placed in the die between the extension die mounting plate 1 241 and the extension die mounting plate 2 341. Once the stamping parts need to be replaced, the fixed limit mounting plate 1 26 and the limit mounting plate 2 341 can be disassembled. The fixing bolts 27 and 37 of mounting plate 2 36 simultaneously push the extension mold mounting plate 241 and the extension mold mounting plate 241 forward until the limiting mounting plate 3 243 abuts against the rear side of the pressure box 21 and the limiting mounting plate 4 343 abuts against the rear side of the fixed base 31. During sliding, the sliding of the extension T-shaped sliding plate 1 242 and the T-shaped sliding plate 1 23 in the T-shaped through groove 1 22 and the sliding of the extension T-shaped sliding plate 2 342 and the T-shaped sliding plate 2 33 in the T-shaped through groove 2 32 maintains the stability of movement. Finally, the fixing bolts 244 and 344 fix the limiting mounting plate 3 243 to the pressure box 21 and the limiting mounting plate 4 343 to the fixed base 31, respectively, thus completing the rapid stamping of different stamping parts dies. During the conversion, when the upper mold mounting plate 24 and the lower mold mounting plate 34 are not pushed forward, the front electric push rod 12 can be activated after the stamping is completed to drive the chip blowing box 13 in the front lifting groove 11 to rise. This simultaneously activates the exhaust fan 133 on the outer wall of the connecting plate 132 inside the front chip blowing box 13, thereby blowing external air through the filter screen 131 and blowing it into the mold between the upper mold mounting plate 24 and the lower mold mounting plate 34, blowing the debris backward until it is blown into the mesh bag 142. Similarly, when the extension mold mounting plate 1 241 and the extension mold mounting plate 2 341 are between the lower pressure box 21 and the fixed base 31, the rear electric push rod 12 can be driven to control the rear chip blowing box 13 to rise, and the front chip blowing box 13 is in the inner cavity of the lifting groove 11.Furthermore, the mesh bag 142 can be used to catch debris blown forward from the rear chip blower box 13 by pulling out the two insert rods 14 inserted into the rear square insert rings 345 and inserting them into the two front square insert rings 345. Simultaneously, the inclined guide plate 143 on one side of the two insert rods 14 prevents debris between the molds from being blown out from both sides during blowing, thus serving a guiding function.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
