Description

Technical Field

[0001] The utility model relates to a transmission device for springs, in particular to a transmission device during the cold punching and quenching heat treatment process of springs. Background Art

[0002] Quenching is a heat treatment process method in which steel is heated above the critical temperature, held for a certain time, and then cooled at a rate greater than the critical cooling rate to obtain an unbalanced structure mainly composed of martensite (or bainite can also be obtained according to needs or a single-phase austenite can be maintained). Quenching is the most widely used process method in the steel heat treatment process.

[0003] During the heat treatment quenching process of large springs, the high-temperature springs are immersed in a cooling pool for cooling. The cooling time is long, and the cooling pool is very large. After a period of cooling, the water temperature near the springs in the cooling pool rises rapidly, and the springs cannot be cooled quickly and evenly. Moreover, due to the large area occupied by the cooling pool, it takes a long time to replace and filter the water in the cooling pool, thus affecting the quenching efficiency. Summary of the Invention

[0004] The utility model provides a device for spring transmission for cold punching quenching. The cooling pool for cold punching quenching is small, and the cooling water flushes and cools as a whole from above. The transmission device has a simple structure, drives the springs to move in and out quickly and rotate, improves the quenching effect, and solves the technical problem of the influence of uneven cooling water temperature on the quenching quality during the spring quenching process in the prior art.

[0005] The above technical problems of the present utility model are solved by the following technical solutions: A transmission device for spring impact cold quenching, comprising a frame located above a water tank, a spring feeding rack provided on one side of the frame, a cold impact support table provided at the center of the frame, a height difference exists between the feeding rack and the cold impact support table, a feeding structure and a discharging structure are provided on both sides of the cold impact support table, the feeding structure includes a feeding lifting frame and a feeding plate, and the discharging structure includes a discharging lifting frame and a discharging plate. Quick cooling and flushing are carried out at the cold impact support table, and the water after flushing falls from the frame into the water tank. The spring is sent from the feeding rack to one side of the feeding lifting frame, and the spring is transported to the middle cold impact support table by the lifting of the lifting frame, and then high-speed and large-volume cold impact is carried out. The cold impact position is significantly lower than the feeding rack, and the large-flow cold impact will not affect the subsequent feeding of the spring. After cold impact quenching, the quenched spring is transported out by using the discharging lifting frame. Due to the large-flow cold impact, the lifting time on both sides just completes the cold impact. That is, after the feeding arrives, the feeding lifting frame drops to roll the spring to be quenched into the cold impact support table, and then the feeding lifting frame rises again to pick up the next spring to be processed. During this period, the spring located on the cold impact support table has completed high-speed quenching and can be quenched for the next spring. All components are operating during the whole process, with high efficiency, and the large-flow cold water for cold impact quenching has good effect.

[0006] Preferably, the feeding lifting frame includes feeding columns that are parallel to each other. Feeding tracks are opened on the feeding columns. A feeding plate seat is installed in the feeding tracks. A feeding plate is fixed on the feeding plate seat. The included angle between the feeding plate seat and the feeding plate is an acute angle. The design of the acute angle makes the spring stably located on the feeding plate, improving the feeding stability. The feeding plate seat slides in the track, thereby transporting the spring from the upper feeding rack to the lower cold impact support table.

[0007] Preferably, the feeding plate seat is a rectangular frame body, and the feeding track is in an arc shape protruding towards the cold impact support table. Design an arc-shaped track protruding outwards to change the angle of the feeding plate seat, so that the feeding plate tilts towards the cold impact support, and the spring on the feeding plate can be smoothly poured onto the cold impact support table for high-speed flushing, cooling and quenching.

[0008] Preferably, the discharging lifting frame includes discharging columns that are parallel to each other. Discharging tracks are opened on the discharging columns. A discharging plate seat is installed in the discharging tracks. A discharging plate is fixed on the discharging plate seat. The discharging plate seat and the discharging plate are arranged at an acute angle. The design of the acute angle makes the spring stably located on the discharging plate, improving the discharging stability.

[0009] Preferably, the discharging track is inclined, and the discharging plate seat is rectangular. It is convenient for the spring after quenching to be discharged.

[0010] Preferably, driving motors are installed at the upper ends of both the feeding lifting frame and the discharging lifting frame. The driving motors drive the reel wheels around which the pulling ropes are wound. One end of the pulling rope on the feeding lifting frame is fixed to the feeding plate, and one end of the pulling rope on the discharging lifting frame is fixed to the discharging plate. The pulling ropes drive the feeding plate seat and the discharging plate seat to move within the guide rails, thereby driving the movement of the feeding plate and the discharging plate.

[0011] Preferably, two parallel rollers are installed on the punching and cooling support table. The two rollers form the supporting surface for the spring. One feeding guide plate and one discharging guide plate are respectively arranged on both sides of the rollers. The feeding guide plate and the discharging guide plate are both inclined, inclined from the feeding end to the discharging end. A liftable ejector plate is arranged between the two rollers. The inclined feeding guide plate and discharging guide plate connect the feeding plate and the punching and cooling support table and the discharging plate and the punching and cooling support table, making it more convenient for the spring to enter and exit the quenching process. After the quenching is completed, the ejector plate ejects the spring located on the rollers onto the discharging guide plate, and then the spring slides onto the discharging plate along the discharging guide plate.

[0012] Preferably, the feeding guide plate is connected to the feeding plate, and the discharging guide plate is connected to the discharging plate. The feeding guide plate and the discharging guide plate are located on the same inclined plane.

[0013] Therefore, the transmission device for spring punching and cooling quenching of the present utility model has the following advantages: The feeding structure and the discharging structure enable the spring delivered by the feeding structure to be quickly subjected to high-speed flushing and cooling treatment, improving the quenching efficiency. The spring is transported to the punching and cooling support table through the lifting structure. Through the arrangement of the guide rail structures on both sides, the spring rolls onto the punching and cooling support table more smoothly and easily. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solution of the utility model will be further specifically described below through embodiments in combination with the drawings.

[0017] Embodiment:

[0018] As shown in Figure 1 and 2As shown in the figure, a transmission device for spring impact cold quenching includes a frame 1. On one side of the frame 1, a spring feeding rack 2 is arranged. Around the frame 1, a frame baffle is arranged. Below the frame 1 is a reservoir (not shown). A feeding guide rail 3 is installed on the spring feeding rack 2. A feeding seat 4 is installed on the feeding guide rail 3. One end of the feeding seat 4 is installed with a pushing plate 5, and the pushing plate 5 is driven by a pushing cylinder.

[0019] In the center of the frame 1, a cold stamping support table is arranged. Two rollers 21 parallel to each other are installed on the cold stamping support table. The two rollers 21 are driven by a driving motor installed on the cold stamping support table. The rolling of the two rollers 21 drives the springs to be quenched located on the rollers to roll, so as to achieve full quenching. The two rollers 21 form a V-shaped support surface. The distance between the centers of the two rollers 21 is smaller than the diameter of the springs to be quenched. On both sides of the two rollers 21, a feeding guide plate 18 and a discharging guide plate 20 are respectively installed. Both the feeding guide plate 18 and the discharging guide plate 20 are inclined, and are inclined from the feeding end to the discharging end. Between the two rollers 21, a liftable ejector plate 19 is provided, and the ejector plate 19 is also inclined. When the ejector plate 19 ejects, the feeding guide plate 18, the ejector plate 19 and the discharging guide plate 20 are on the same inclined plane. The lift of the ejector plate 19 is controlled by an ejecting cylinder 13.

[0020] On both sides of the cold stamping support table, a feeding lifting frame 22 and a discharging lifting frame 23 are respectively installed. The feeding lifting frame 22 includes feeding columns 9 parallel to each other. On the feeding columns 9, a feeding track 10 is provided. The feeding track 10 is in an arc shape protruding towards the cold stamping support table. A feeding plate seat 11 is installed in the feeding track 10. The feeding plate seat 11 is a rectangular frame, and the upper and lower ends of the feeding plate seat 11 are located in the feeding track 10. A feeding plate 12 is fixed on the feeding plate seat 11. The included angle between the feeding plate seat 11 and the feeding plate 12 is an acute angle. A driving motor 6 is installed at the upper end of the feeding lifting frame 22. The driving motor 6 drives a reel 7 to rotate. A pulling rope 8 is wound around the reel 7. One end of the pulling rope 8 on the feeding lifting frame 22 is fixed on the feeding plate 12. By pulling the pulling rope 8, the feeding plate seat 11 moves in the feeding track 10, which drives the feeding plate 12 to lift.

[0021] The discharging lifting frame 23 includes discharging columns 14 parallel to each other. On the discharging columns 14, a discharging track 15 is provided. The discharging track 15 is in a straight line shape. A discharging plate seat 16 is installed in the discharging track 15. The discharging plate seat 16 is rectangular, and both ends of the discharging plate seat 16 are located in the discharging track 15. A discharging plate 17 is fixed on the discharging plate seat 16. The discharging plate seat 16 and the discharging plate 17 are arranged at an acute angle. A driving motor is installed at the upper end of the discharging lifting frame 23. The driving motor drives a reel. A pulling rope is wound around the reel. One end of the pulling rope of the discharging lifting frame is fixed on the discharging plate 17.

[0022] In use, when the spring to be quenched on the feeding rack 2 is transported to the front of the feeding lifting rack 22, the pushing plate 5 pushes the spring to be quenched onto the feeding plate 12. The driving motor 6 drives the reel 7 to rotate, so that the feeding plate seat 11 and the feeding plate 12 move downward. Since the feeding track 10 protrudes outward, when moving to the protruding part, the feeding seat 11 tilts, and thus the spring to be quenched is dumped from the feeding plate 12 onto the feeding guide plate 18. The inclined feeding guide plate 18 transports the spring to be quenched to the support surface formed by the two rollers 21. The rollers 21 roll to drive the spring to roll. The upper punching and cooling head pours a large amount of water at one time to cool and quench the spring to be quenched. After quenching, the ejecting plate 19 rises to eject the spring from the roller support surface. The spring rolls along the discharging guide plate 20 onto the discharging plate 17. The driving motor on the discharging lifting rack 23 drives the reel to rotate, and the discharging plate seat drives the discharging plate to rise so as to output the processed spring. And at the feeding end, the processing of the next cycle of the spring is still being repeated.
