Description

Technical Field

[0001] This invention belongs to the field of rotor internal gear stamping technology, specifically referring to a rotor internal gear stamping device. Background Technology

[0002] In the stamping process, stamping speed is a critical factor. Most existing stamping equipment lacks an effective automatic speed adjustment mechanism. When the stamping speed is too high, it can easily lead to brittle fracture of the stamped gear. This is because the gear experiences excessive impact force under high-speed stamping, resulting in uneven internal stress distribution that cannot be adjusted in time. Furthermore, after stamping, debris and other impurities remain on the die. Traditional cleaning methods, mostly manual, are inefficient and can easily damage the die. Removing the stamped gear from the die after processing is also a crucial step. Traditional methods may rely on manual labor or additional mechanical structures for ejection, which can lead to delays in timely ejection. Summary of the Invention

[0003] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a rotor internal gear stamping device. Based on the principle that the stamping force during gear stamping must be both large (to generate sufficient stamping force to complete gear forming) and not excessive (excessive impact force can lead to brittle fracture of the gear), an adaptive centrifugal outward friction method is used to generate rotational damping, achieving the technical effect of adaptive non-destructive stamping of the gear. Furthermore, by utilizing the driving force during stamping and employing a multi-directional linkage method, multiple technical effects are achieved, including gear unloading and pneumatic cleaning of the mold.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: This solution provides a rotor internal gear stamping device. During the stamping process of the rotor internal gear, the stamping forming of the gear requires a suitable stamping force. On the one hand, the stamping force must be large enough to ensure smooth gear forming; on the other hand, the stamping force cannot be too large, because excessive impact force can easily cause brittle fracture of the gear. Based on this, the present invention adopts a unique method of generating rotational damping through adaptive centrifugal outward friction. During the stamping process, when the stamping speed is too fast, the friction rod rotates outward along the fixed end under the action of rotational centrifugal force, contacting and rubbing against the enclosure shell to generate rotational damping, thereby effectively controlling the stamping force within a suitable range and effectively preventing brittle fracture of the gear caused by excessive stamping speed, achieving the technical effect of adaptive non-destructive stamping of the gear. In addition, the present invention also cleverly utilizes the driving force during stamping and employs a sophisticated multi-directional linkage design. While the stamping action is in progress, through the coordinated linkage between various components, not only is the unloading of the stamped gear automated, but the mold can also be pneumatically cleaned simultaneously. This multi-directional linkage method makes full use of the energy and motion relationships in the stamping process, achieving multiple technical effects of gear unloading and mold pneumatic cleaning in a simple and efficient way, which greatly improves the overall performance and production efficiency of the gear cold stamping device.

On the side wall of the fixed block 14, an airbag 23 is disposed between the upper fixed limiting plate 21 and the lower movable extrusion plate 22.

[0025] like Figure 1 , Figure 6 , Figure 7 As shown, the adaptive speed control device 3 includes a meshing gear disk 6, a centrifugal outward friction rod 7, and a retaining shell 8. The meshing gear disk 6 is rotatably mounted on the cold stamping frame 1 and is meshed with the cold stamping mechanism 2.

The support spring 11 is inclined between the friction rotating rod 10 and the meshing gear disk 6.

[0026] In practical use, the stamping die to be used is inserted into the dovetail groove 45, and the locking bolt 46 is rotated to lock the die onto the dovetail groove locking die replacement part 5. The sheet metal to be stamped is placed between the stamping dies, and the drive motor 40 is started. The drive motor 40 rotates, which drives the drive gear 38 to rotate. The drive gear 38 rotates, which drives the drive rack 39 to rotate. The drive rack 39 rotates, which moves the stamping cylinder 36 downward. The downward movement of the stamping cylinder 36 moves the upper die replacement part 42 downward. The downward movement of the upper die replacement part 42 moves the stamping die mounted on it downward. As the mold moves downwards, it stamps the sheet metal. Simultaneously, the stamping cylinder 36 moves downwards, causing the meshing rack 41 to move downwards as well. The meshing rack 41 then rotates the meshing gear disc 6, which in turn rotates the fixed end 9. The fixed end 9 then rotates the friction rod 10. When the stamping speed is too high, the friction rod 10, under the action of centrifugal force, rotates outwards along the fixed end 9, contacting and rubbing against the enclosure shell 8, generating rotational damping. This reduces the speed of the stamping cylinder 36, effectively preventing brittle fracture of the sheet metal due to excessive stamping speed. After stamping is completed... The drive motor 40 reverses, causing the stamping cylinder 36 to move upward. The upward movement of the stamping cylinder 36 causes the connecting plate 32 to move upward. The upward movement of the connecting plate 32 causes the ejector trigger rack 33 and the pneumatic cleaning trigger rod 34 to move upward. The upward movement of the ejector trigger rack 33 causes the linkage gear plate 16 to rotate. The rotation of the linkage gear plate 16 causes the eccentric column 18 to rotate. The rotation of the eccentric column 18 causes the actuating rod 15 to rotate. The rotation of the actuating rod 15 causes the locking column 28 to move. The movement of the locking column 28 causes the ejector plate 20 to move along the locking groove 25, thereby moving the stamped tooth... The wheel is inserted into the material holding frame 47, and at the same time, the pneumatic cleaning trigger rod 34 moves upward. The upward movement of the pneumatic cleaning trigger rod 34 pushes the lower movable extrusion plate 22 to move upward along the limiting slide groove 30. The upward movement of the lower movable extrusion plate 22 extrudes the air bag 23, thereby transmitting the gas in the air bag 23 to the gas transmission pipe 24, and then to the gas transmission chamber 26. The gas is then blown out through the air hole 27 to clean the upper and lower molds, making it easier for the next stamping. The above is the specific working process of this invention. This step can be repeated for the next use.
