Description

Technical Field

[0001] This invention belongs to the field of mechanical parts processing technology, specifically referring to a stamping and grinding device for processing mechanical parts. Background Technology

[0002] In the manufacturing process of mechanical parts, stamping is an efficient and commonly used forming process, widely applied to the production of various metal sheet parts. However, during the stamping process, due to the shearing and stretching forces acting on the sheet metal, burrs of varying degrees are often generated on the edges of the workpiece. These burrs not only affect the appearance and dimensional accuracy of the parts, but may also reduce the fit quality of subsequent assembly, and even affect the fatigue strength and service life of the parts due to stress concentration. In addition, sharp burrs also pose safety hazards such as scratching operators or damaging other parts. Therefore, burr removal is an indispensable process after stamping.

[0003] Traditional machining methods typically treat stamping and deburring as two separate processes: parts are first formed using stamping equipment, and then transferred to specialized grinding or deburring equipment for edge finishing. This separate processing flow not only requires additional equipment investment and energy consumption, but also increases the time spent on handling and positioning between processes, leading to a decrease in overall production efficiency. Furthermore, traditional grinding and deburring methods often fail to effectively integrate with debris removal, leaving metal debris on the workpiece surface or in the working area. If not removed promptly, this debris may adhere to the parts, affecting subsequent painting, inspection, or assembly quality, and may even enter the product's interior, posing a potential threat to the final product's performance and reliability.

[0004] Therefore, there is an urgent need in the existing technology for an integrated device that can organically combine stamping and deburring to improve processing efficiency, reduce overall costs, and achieve simultaneous processing of burrs and chips, thereby meeting the production requirements of modern mechanical parts for high precision, high efficiency, and high cleanliness.

The deburring component 21 is engaged and slidably mounted on the linkage pulley 20 and the stable connecting plate 11.

[0027] In practical use, the sheet metal to be processed is placed on the lower stamping die 40 and clamped by the limit ball 44. The stamping hydraulic rod 38 is activated, and the stamping hydraulic rod 38 extends, driving the upper stamping die 39 to press towards the lower stamping die 40. With the cooperation of the lower stamping die 40, the excess part of the sheet metal is sheared off. When the upper stamping die 39 moves down, it drives the drive rack 41 to move down. The downward movement of the drive rack 41 drives the lever gear 9 to rotate counterclockwise. The counterclockwise rotation of the lever gear 9 drives the drive gear column 13 to rotate counterclockwise. At this time, the one-way meshing gear 14 does not mesh with the drive gear column 13, that is, the one-way meshing gear 14 does not rotate. After stamping and shearing, the electric push rod 29 is activated. The electric push rod 29 extends and descends, driving the upper stamping die 39 to move the lower stamping die 40 ... The constraint semi-ring 30 descends, releasing the constraint ring plate 27. At this time, the telescopic fitting rod 23 extends and retracts towards the mechanical part under the action of the adaptive spring 26. The grinding head 24 presses against the edge of the mechanical part. The stamping hydraulic rod 38 extends, causing the stamping upper die 39 to move upward. The upward movement of the stamping upper die 39 causes the drive rack 41 to move upward. The upward movement of the drive rack 41 causes the lever gear 9 to rotate clockwise. The clockwise rotation of the lever gear 9 causes the drive gear column 13 to rotate clockwise. At this time, the one-way meshing gear 14 meshes with the drive gear column 13. The clockwise rotation of the drive gear column 13 causes the one-way meshing gear 14 to rotate clockwise. The clockwise rotation of the one-way meshing gear 14 causes the drive shaft 15 to rotate clockwise. The clockwise rotation of the drive shaft 15 causes the belt to rotate. Wheel 17 rotates clockwise, which in turn drives the transmission belt 12 to rotate clockwise. The transmission belt 12 then drives the linkage pulley 20 to rotate clockwise, which in turn drives the telescopic contact rod 23 to rotate clockwise. The telescopic contact rod 23 then drives the grinding head 24 to rotate clockwise. The grinding head 24 grinds the burrs at the sheared parts of the mechanical parts. Simultaneously, the rotation of the telescopic contact rod 23 drives the cleaning blades 25 to rotate, blowing away the grinding debris. The blown debris slides down the support guide table 46, further improving the quality of the grinding and deburring. Simultaneously, the clockwise rotation of the linkage pulley 20 drives the linkage gear 32 to rotate counterclockwise. The rotation of the needle drives the transmission gear 33 to rotate clockwise, which in turn drives the transmission gear 34 to rotate counterclockwise. The counterclockwise rotation of the transmission gear 34 drives the transmission gear 35 to rotate clockwise, which in turn drives the reversing gear 36 to rotate counterclockwise. The counterclockwise rotation of the reversing gear 36 drives the rotating column 37 to rotate counterclockwise, which in turn drives the stamping die 40 to rotate counterclockwise. The counterclockwise rotation of the stamping die 40 drives the mechanical parts to rotate counterclockwise. By simply using the stamping force, the multiple technical effects of omnidirectional rotation, grinding, deburring, and cleaning of the edges of the mechanical parts are achieved. The above is the specific working process of this invention. This step can be repeated for the next use.
