Description

Technical Field

[0001] This utility model relates to the field of pin processing technology, specifically a continuous production line for pin surface strengthening treatment. Background Technology

[0002] As a commonly used connecting component in mechanical structures, the surface properties of pins have a significant impact on the overall reliability and service life of the machinery. Currently, surface strengthening treatment of pins is usually carried out manually or with semi-automatic equipment, which presents many problems.

[0003] When operating manually, the inconsistent techniques and force applied by workers can lead to unstable quality in the surface strengthening treatment of pins. For example, uneven heating can easily occur during surface quenching, affecting the strengthening effect. While semi-automatic equipment improves production efficiency to some extent, the connections between processes are not smooth enough, requiring frequent manual handling of pins for processing, which increases labor intensity and production cycle. This cannot meet the demands of modern manufacturing for high-quality and high-efficiency production. Therefore, it is necessary to develop a continuous production line for pin surface strengthening treatment to perform pin processing operations. Utility Model Content

[0024] A connecting groove 9 is provided at the top of the reinforced sewage tank 1. A guide plate 10 is fixedly installed on one side of the top of the reinforced sewage tank 1. The guide plate 10 connects the connecting groove 9 and the middle of the storage and conveying frame 2. An L-shaped support frame 11 is fixedly installed at the top of the reinforced sewage tank 1. A supporting gantry frame 12 is fixedly installed on one side of the L-shaped support frame 11 at the top of the reinforced sewage tank 1. A quenching device 13 is fixedly installed at the top of the supporting gantry frame 12. A quenching ring 14 is fixedly installed at the bottom of the quenching device 13. The fire ring 14 is electrically connected to the quenching device 13. A first motor 15 is fixedly installed on one side of the L-shaped support frame 11. A transmission shaft 16 is fixedly installed on the output shaft end of the first motor 15. A positioning groove 17 is provided on one side of the top of the L-shaped support frame 11. A second motor 18 is fixedly installed on the L-shaped support frame 11 on one side of the first motor 15. An adjusting screw 19 is fixedly installed on the output shaft end of the second motor 18. The adjusting screw 19 is located inside the positioning groove 17, and the interior of the positioning groove 17 is far from the second motor 15. A movable mounting block 20 is fixedly installed on one side of the inner wall of the 8th motor. The side of the adjusting screw 19 away from the second motor 18 is rotatably connected to the side of the movable mounting block 20. The outer end of the adjusting screw 19 is threadedly connected to a positioning screw block 21. A transmission guide rod 22 is fixedly installed on the top of the positioning screw block 21. A transmission top block 23 is fixedly installed on the side of the transmission guide rod 22 near the supporting gantry frame 12. A discharge chute 24 is opened on one side of the top of the reinforced sewage tank 1. A drain pipe 25 is fixedly installed on one side of the reinforced sewage tank 1. A load-bearing support plate 26 is fixedly installed at the bottom of the reinforced sewage tank 1. Second support legs 27 are fixedly installed at the four corners of the bottom of the load-bearing support plate 26. The first motor 15 is started to rotate the transmission shaft 16, which in turn drives the pin shaft to rotate. The second motor 18 is started to rotate the adjusting screw 19, which causes the positioning screw block 21 to move parallel on the adjusting screw 19, driving the transmission guide rod 22 and the transmission top block 23 to move, transmitting the pin shaft to the quenching ring 14, and performing quenching processing on the pin shaft through the quenching ring 14.

[0025] Working Principle: When surface strengthening treatment of the pin is required, it is first stably placed in the desired position by the second support leg 27 and the first support leg 3. An external power supply is connected to provide power to the electrical equipment on the device. Each device on the device is controlled by a controller. First, the pin to be processed is placed in the storage and conveying frame 2. The processing parameters of each device are preset. The electric push rod 6 is started to adjust the height of the push rod 7, which pushes the arc-shaped feeding push plate 8 to rise or fall. Through the special design of the arc-shaped feeding push plate 8, other pins in the storage and conveying frame 2 are effectively limited, without affecting the descent of the arc-shaped feeding push plate 8 or the subsequent feeding operation. When rising, the pin on the arc-shaped feeding push plate 8 is pushed out of the storage and conveying frame 2, so that it rolls to the middle of the transmission shaft 16 and the guide inclined plate 10. The first motor 15 is started to rotate the transmission shaft 16, which drives the pin to rotate at the same time. When the shaft falls onto the connecting slot 9, it is positioned on one side of the transmission top block 23. The second motor 18 is started to rotate the adjusting screw 19, causing the positioning screw 21 to move parallel on the adjusting screw 19. This drives the transmission guide rod 22 and the transmission top block 23 to move. The transmission top block 23 moves the pin shaft to one side of the quenching ring 14, transmitting the pin shaft into the quenching ring 14. The pin shaft is then quenched through the quenching ring 14. During quenching, the water used for cooling is discharged into the reinforced wastewater tank 1 through the connecting slot 9 and the slot below the quenching ring 14, and subsequently discharged through the drain pipe 25. After quenching, the pin shaft is pushed into the discharge chute 24 by the transmission top block 23. Other pin shafts are then continuously processed. A conveyor belt can be built on one side of the discharge chute 24 to transport the surface-strengthened pin shafts, or they can be directly discharged into the discharge frame through the discharge chute 24 and transferred to the next processing step.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
