Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping equipment technology, and in particular to a stamping equipment for manufacturing shaft seal sleeves. Background Technology
[0002] In the field of mechanical manufacturing, shaft seal sleeves are key components that ensure the sealing performance of rotating shafts. Their machining accuracy and production efficiency directly affect the overall sealing effect and manufacturing cost of the equipment. Existing devices typically use limiting strips on both sides of the sleeve die holder to restrict its movement through rigid contact. However, during long-term movement, friction and collisions continuously occur between the sleeve die holder and the limiting strips. This continuous interaction leads to wear at the contact points between the limiting strips and the die holder, gradually increasing the clearance between them. As the clearance widens, the sleeve die holder is prone to slight displacement during movement, making it impossible to maintain a precise preset position. The accumulation of these slight displacements directly affects the stamping accuracy. To ensure product quality, frequent compensation adjustments to the die holder position are required in subsequent processes, increasing operational complexity and production uncertainty. Therefore, improvements are needed to address these issues. Utility Model Content

Through the above structural cooperation, the convenient adsorption and transfer of the stamped sealing sleeve is realized, providing reliable structural support for batch unloading and improving unloading efficiency.
[0015] In this utility model, a rotating rod 2 is fixedly connected to the center of the top surface of the arc-shaped fixed plate. The rotating rod 2 is in the shape of an "r". One end of the rotating rod 2 is rotatably mounted on the top surface of the stamping table 1. The stamping table 1 is provided with a rotating box located at the rotating rod 2. A driven gear 10 is fixedly connected to the rotating rod 2 on the same axis inside the rotating box. A driving gear is meshed on one side of the driven gear 10. A first motor is fixedly connected to the bottom surface of the driving gear on the same axis at a location on the bottom surface of the rotating box. The first motor is a 57BYG250H type stepper motor. Both the driven gear 10 and the driving gear are made of 20CrMnTi material, which has high gear transmission accuracy and strong load-bearing capacity. Through the above structural cooperation, the flexible rotation of the adsorption plate 12 is realized, the feeding range is expanded, and the operational flexibility of the equipment is improved. The feeding component includes a hydraulic push rod platform 4. Multiple bushing conveyor frames 7 are fixedly connected at equal intervals on one side of the hydraulic push rod platform 4. A guide cylinder 8 is fixedly connected to the bottom surface of the bushing conveyor frame 7 at the upper end of the sleeve mold base 14. A hydraulic cylinder is installed at the top of the push rod platform 4; the hydraulic cylinder is HOB63×100; the bushing conveyor frame 7 is made of Q235 steel plate, which is low in cost and has sufficient structural strength; through the above structural cooperation, a stable feeding channel is constructed to ensure that the raw material can fall accurately into the sleeve mold base 14, thus improving the feeding accuracy; the top surface of the bushing conveyor frame 7 is provided with a sliding groove, one end of the bottom surface of the sliding groove is provided with a through hole communicating with the guide cylinder 8, and the other end of the bottom surface of the sliding groove is movably provided with a push rod 9, the top of the push rod 9 is fixedly connected to a crossbar, and multiple connecting rods are equidistantly provided on one side of the crossbar, one end of the connecting rod is fixedly connected to a push plate, and the telescopic end of the hydraulic cylinder is fixedly connected to the push plate; both the push rod 9 and the push plate are made of 45# steel, which has good rigidity and can stably push the raw material to move; through the above structural cooperation, the orderly pushing of the raw material is realized, ensuring the continuity of the feeding process and further improving production efficiency; Working Principle: In the use of this utility model, firstly, an external motor drives either of the two synchronous pulleys to rotate, which in turn drives the toothed belt to move. At the same time, the feeding assembly starts to operate: the hydraulic cylinder at the top of the hydraulic push rod platform 4 extends and retracts, driving the push plate to move. The push plate drives the push rod 9 to slide in the groove of the bushing conveyor frame 7 through the connecting rod and the crossbar, pushing the raw material of the shaft sealing sleeve in the groove towards the through hole. The raw material falls into the sleeve mold base 14 below through the guide cylinder 8, completing the feeding. Then, driven by the toothed belt, the connecting rod on its outer wall drives the limiting ring 15 and the sleeve mold base 14 to move along the sleeve guide groove seat 13. During the movement, the sleeve mold base 14 passes through the guide arc frame 5. The limiting guide strip 6 in the guide arc frame 5 passes through the arc-shaped through grooves on both sides of the sleeve mold base 14 to limit it and prevent shaking. The limiting ring 15 further fixes the sleeve mold base 14 to prevent lateral deviation. When the sleeve die holder 14 moves below the stamping machine 3, the second motor drives the lead screw to rotate, adjusting the position of the sleeve and the stamping machine 3 on the mounting plate to compensate for any minor deviations. Then, the output end of the stamping machine 3 moves downward to stamp the raw material inside the sleeve die holder 14. After stamping, the sleeve die holder 14 continues to move below the adsorption plate 12. The electric push rod extends and retracts, driving the lifting plate and lifting rod to move up and down, causing the adsorption plate 12 to descend and contact the stamped sealing sleeve. The adsorption plate 12 is energized and magnetized to adsorb the sealing sleeve. Then, the first motor drives the drive gear to rotate, and the drive gear meshes with the driven gear 10 to rotate the rotating rod 2, moving the adsorption plate 12 and the adsorbed sealing sleeve to the designated position. The adsorption plate 12 is de-energized and demagnetized, and the electric push rod controls the adsorption plate 12 to rise, completing the batch unloading. This cycle is repeated to achieve continuous production. At this point, the device is in use.
