Description

Technical Field

[0001] This utility model relates to the technical field of tempering apparatus for quenching and tempering metal workpieces, and in particular to a tempering apparatus for quenching and tempering metal workpieces. Background Technology

[0002] In the existing technology, when tempering the metal workpieces (fasteners) that are matched with fine-rolled threaded steel bars, a tempering device such as CN222205311U for bolt tempering is often used. However, it only allows the tray holding the metal workpieces to rotate and circulate, without taking into account the problem that when the tray is large, the metal workpieces on the inner and outer sides of the tray will have different tempering effects. Utility Model Content

[0003] Therefore, it is necessary to provide a tempering device for quenching and tempering metal workpieces to address the technical problem of different tempering effects on the inner and outer sides of the aforementioned tray.

[0004] To achieve the above objectives, this utility model provides a tempering device for quenching and tempering metal workpieces, comprising a frame, a tray, and a top cover. A heating plate is installed inside the frame, and an annular plate is slidably engaged on the frame. The annular plate has a chamfer. A rotating shaft is rotatably mounted on the top cover, and an inclined push plate and a push flat plate are mounted on the rotating shaft. The push flat plate is spaced apart from the upper surface of the tray. A drive shaft is rotatably mounted on the frame and is slidably engaged with the rotating shaft. A bevel gear one is mounted on the drive shaft, and a bevel gear two is installed inside the frame. The bevel gear one and bevel gear two are meshed together. A crank mechanism is mounted on the bevel gear two, and the output end of the crank mechanism is hinged to the annular plate.

[0005] Preferably, the frame is equipped with a rotary drive device, a gearbox, and a linear actuator. The output ends of the rotary drive device and the gearbox are connected to the drive shaft, and the output end of the linear actuator is connected to the top cover.

[0006] Preferably, an annular leak-proof plate is installed at the bottom of the tray, and the annular leak-proof plate is slidably connected to the annular plate.

[0007] Preferably, the frame is equipped with several support rods, and the bottom of the tray and the annular plate are provided with support grooves that are adapted to the support rods.

[0008] Preferably, the tray is provided with several card slots.

[0009] Preferably, the bottom outer side of the push plate is chamfered, and an elastic pad is installed at the bottom of the push plate.

[0010] Compared with existing technologies, this technical solution has at least one of the following beneficial effects: 1. By setting up the inclined push plate and the ring plate, the metal workpieces on the tray can be pushed outward and fall onto the ring plate. After the ring plate rises, the metal workpieces slide back onto the tray through the chamfer. Thus, all the metal workpieces on the tray can be pushed, which improves the tempering effect. 2. By using the combination of bevel gear one, bevel gear two and crank mechanism, the driving rotation of the rotating shaft and the pushing and lifting of the ring plate can be completed by a single rotary drive device, saving resources and reducing costs.

[0012] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] Please see Figs. 1 to 3This application provides a tempering device for metal workpieces, including a frame 1, a tray 2, and a top cover 3. A heating plate is fixedly installed inside the frame 1. The heating plate can be an electric heating plate connected to an external power source. An annular plate 4 is slidably engaged on the frame 1. The annular plate 4 has a chamfer. A rotating shaft 5 is rotatably installed on the top cover 3. An inclined push plate 6 and a push plate 7 are fixedly installed on the rotating shaft 5. The push plate 7 is on a straight line passing through the center of the circle, while the inclined push plate 6 is on one side of the center of the circle, thus increasing the inclination. After the rotating shaft 5 descends, the push plate 7 and the upper surface of the tray 2 are separated by a gap large enough to accommodate a flat metal workpiece. Plate 6 abuts against tray 2 or has a very small clearance fit. A drive shaft 8 is rotatably mounted on frame 1. The drive shaft 8 is slidably engaged with rotating shaft 5. The slidable engagement of drive shaft 8 and rotating shaft 5 can be achieved through a square insert and a square slot. A bevel gear 9 is fixedly mounted on drive shaft 8. A bevel gear 10 is rotatably mounted inside frame 1. Bevel gear 9 and bevel gear 10 are meshed. A crank mechanism 11 is fixedly mounted on bevel gear 10. Crank mechanism 11 is a crank transmission mechanism in the prior art. The output end of crank mechanism 11 is hinged to annular plate 4. After rotating shaft 5 descends, it abuts against or has a small clearance fit with the inner wall of the center hole of tray 2.

[0014] In this embodiment, after the tray 2 containing the metal workpieces is placed into the frame 1, the top cover 3 drives the rotating shaft 5 to descend, so that the top cover 3 can close and seal the top of the frame 1. Then, the electric heating plate starts to heat up, and the drive shaft 8 can also drive the rotating shaft 5 to rotate through the sliding engagement with the rotating shaft 5. Thus, the inclined push plate 6 on the rotating shaft 5 can push the metal workpieces on the tray 2 forward. At the same time, the metal workpieces will also slide outward under the action of centrifugal force. When the metal workpieces slide outward to the annular plate 4 located below the tray 2, they can fall onto the annular plate 4. Then, when the annular plate 4 rises, they can fall back onto the tray 2. Thus, there is no situation where the inner and outer rings of the metal workpieces on the large tray 2 are heated differently, resulting in different tempering effects, which improves the tempering strength of the metal workpieces. The function of the push plate 7 is to flatten the tray 2 after the annular plate 4 pushes a large number of metal workpieces onto it, so that the metal workpieces can pass through the gaps, thus preventing the metal workpieces from stacking and affecting the tempering effect. While the drive shaft 8 drives the rotating shaft 5 to rotate, the bevel gear 9 on the drive shaft 8 can drive the bevel gear 10 to rotate, which in turn drives the crank mechanism 11 to rotate, thereby driving the ring plate 4 to rise and fall. This achieves the purpose of driving the rotating shaft 5 to rotate and the ring plate 4 to rise and fall through a single rotary drive device on the drive shaft 8, thus reducing costs.

[0015] In some embodiments, to further improve the cooling efficiency of the quenching roller 4 and the material, a rotary drive device, a reduction gearbox 12, and a linear actuator 13 are fixedly mounted on the frame 1. The rotary drive device can be a customized low-speed servo motor, which, in conjunction with the reduction gearbox in the prior art, can further achieve the effect of controlling the rotational speed. The linear actuator 13 can be an electric cylinder. The output end of the rotary drive device and the reduction gearbox 12 is connected to the drive shaft 8, and the output end of the linear actuator 13 is connected to the top cover 3. The rotary drive device and the reduction gearbox 12 can drive the drive shaft 8 to rotate at a slower speed, and with the adjustable gear ratio of bevel gear 19 and bevel gear 20, the lifting speed of the annular plate 4 can be further reduced. The linear actuator 13 can drive the top cover 3 and the rotating shaft 5 to lift and lower. Both can be installed on the wall or the ground to achieve the driving function.

[0016] In some embodiments, to prevent metal workpieces from falling between the tray 2 and the annular plate 4, an annular leak-proof plate 14 is fixedly installed on the top of the tray 2, and the annular leak-proof plate 14 is slidably connected to the annular plate 4. Through the blocking effect of the annular leak-proof plate 14, when a metal workpiece falls onto the annular plate 4, it is prevented from continuing to fall downwards.

[0017] In some embodiments, to facilitate the sliding connection between the fixed tray 2 and the annular plate 4, a plurality of support rods 15 are fixedly installed on the frame 1, and support grooves 16 adapted to the support rods 15 are provided at the bottom of both the tray 2 and the annular plate 4. By supporting the tray 2 within the support grooves 16 and limiting the annular plate 4, the sliding connection between the fixed tray 2 and the annular plate 4 is achieved.

[0018] In some embodiments, to facilitate the removal of the tempered tray 2, the tray 2 is provided with several slots 17. The tray 2 can be lifted by using hooks or the like in the prior art to engage with the slots 17.

[0019] In some embodiments, to prevent damage to the push plate 7, a chamfer is provided on the bottom outer side of the push plate 7. This prevents the metal workpiece from colliding and squeezing with the push plate 7 when the annular plate 4 rises.

[0020] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
