Description

Technical Field

[0001] This utility model relates to the technical field of quenching mechanisms for high-strength bolt production, and in particular to a quenching mechanism for high-strength bolt production. Background Technology

[0002] In the prior art, such as CN222877992U, there is an automated hot forging and hot forging residual heat quenching device for batch nuts. After the bolts are heated, they are directly put into the quenching tank for quenching. However, the commonly used method is to transport the bolts to the quenching tank by an inclined conveyor belt for continuous quenching. However, in this method, the bolts are fixed on the conveyor belt, which makes the quenching degree of different parts of the bolts different, and the overall strength is weakened. Utility Model Content

[0003] Therefore, it is necessary to provide a quenching mechanism for the production of high-strength bolts to address the technical problem of inconsistent quenching degrees in different parts caused by the fixed placement of bolts.

[0004] To achieve the above objectives, this utility model provides a quenching mechanism for producing high-strength bolts, including a frame, a quenching pool on the frame, an inclined conveyor for inputting and outputting bolts into and out of the quenching pool mounted on the frame, a partition frame mounted on the partition frame, a linear actuator one mounted on the partition frame, a movable plate slidably engaged on the partition frame, the movable plate mounted with a partition plate and an inclined push plate, the output end of the linear actuator one connected to the movable plate, a linear actuator two mounted on the frame, a pressure plate mounted on the output end of the linear actuator two, and a plurality of receiving grooves for accommodating bolts spaced apart on the pressure plate.

[0005] Preferably, two symmetrically arranged adjusting frames are slidably engaged on the frame, a partition frame is slidably connected to the adjusting frames, a rotary drive device is installed on the frame, the two adjusting frames are rotatably mounted with the same bidirectional threaded rod, and the output end of the rotary drive device is drively connected to the bidirectional threaded rod.

[0006] Preferably, a friction pad is installed on the separator frame, and the friction pad abuts against the adjustment frame.

[0007] Preferably, a connecting rod is installed at the output end of the linear actuator II, and a pressure plate is installed at the bottom of the connecting rod.

[0008] Preferably, a limiting rod is installed on the connecting rod, and the frame is provided with a slot for inserting the limiting rod.

[0009] Preferably, a guide shaft is rotatably installed inside the quenching tank, and the guide shaft is in contact with the upper surface of the inclined conveyor.

[0010] Compared with existing technologies, this technical solution has at least one of the following beneficial effects: 1. The bolts are separated one by one by the partition plate and the inclined push plate, and then transported to the quenching tank by the inclined conveyor. The pressure plate presses down to clamp the bolts into the receiving groove one by one. Then the inclined conveyor continues to run, so that the bolts can rotate in the receiving groove, ultimately improving the uniformity of bolt quenching. 2. The adjustment frame allows for the guidance and separation of bolts of different specifications, improving the practicality of the device. Attached Figure Description

Detailed Implementation

[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 Figures 1 to 2This application provides a quenching mechanism for producing high-strength bolts, including a frame 1, a quenching pool 2 on the frame 1, and an inclined conveyor 3 installed on the frame 1 for inputting and outputting bolts into and out of the quenching pool 2. The inclined conveyor 3 is a high-temperature resistant nickel-chromium alloy belt conveyor, etc., which has its own servo motor and can transport bolts at low speed for quenching. A partition frame 4 is installed on the frame 1, and a linear actuator 5 is fixedly installed on the partition frame 4. The linear actuator 5 can be an electric cylinder. A moving plate 6 is slidably connected to the partition frame 4. A partition plate 7 and an inclined push plate 8 are fixedly installed on the moving plate 6. The output end of the linear actuator 5 is connected to the moving plate 6. A second linear actuator 9 is fixedly installed on the frame 1. The second linear actuator 9 can be an electric cylinder. A pressure plate 10 is fixedly installed on the output end of the second linear actuator 9. A plurality of receiving grooves 11 for accommodating bolts are spaced apart on the pressure plate 10. The inclined conveyor 3, the first linear actuator 5, and the second linear actuator 9 can all be connected by a signal processor.

[0014] In this embodiment, before heating, the bolts must be placed flush on the upper surface of the inclined conveyor 3 with the same orientation. After heating, the inclined conveyor 3 outputs the bolts. Before conveying them to the quenching tank 2, the linear actuator 5 can drive the moving plate 6 to move up and down at intervals. The moving plate 6 can drive the partition plate 7 and the inclined push plate 8 to separate the bolts one by one. During separation, one bolt can be stuck between the partition plate 7 and the inclined push plate 8, while the remaining bolts are pushed apart by the chamfer at the bottom of the inclined push plate 8. The signal is transmitted through the signal processor. After the bolt approaches the partition plate 7, the inclined push plate 8 rises again to put in the next bolt. After separation, the inclined conveyor 3 can continue to convey the bolts to the quenching tank 2. Since the inclined conveyor 3 has a small inclination angle and a certain friction with the bolts, the bolts will not roll on the inclined conveyor 3. When the bolts are conveyed into the quenching tank 2, the linear actuator 9 drives the pressure plate 10 to press down, so that the separated bolts can be stuck in the receiving groove 11 one by one, thereby achieving the desired separation during the inclined conveyor process. During the continued operation of machine 3, the bolts can be driven to rotate, avoiding the problem of inconsistent quenching effect and overall strength caused by prolonged contact between the bottom of the bolts and the inclined conveyor 3. After a certain period of time, the pressure plate 10 can rise, allowing this batch of bolts to continue to be conveyed out by the inclined conveyor 3. The gap between the separator 4 and the inclined conveyor 3 can only accommodate one row of bolts, so there will be no stacking. When the bolts rotate in the receiving groove 11, the subsequent bolts will continue to move forward. The linear actuator 5 can block the next batch of bolts for a certain period of time through the inclined push plate 8, thereby separating the two batches of bolts. In the prior art, the inclined conveyor 3 operates slowly to drive the bolts for quenching. In this application, since the bolts need to rotate in batches to improve the bolt strength, the operating speed of the inclined conveyor 3 can be appropriately increased so as not to affect the overall quenching efficiency. The width of the receiving groove 11 and the thickness of the pressure plate 10 are both greater than the width of the bolts, so they can be adapted to bolts of different specifications. The pressure plate 10 does not need to abut against the upper surface of the inclined conveyor 3 when it is working.

[0015] In some embodiments, to uniformly quench bolts of different specifications, two symmetrically arranged adjusting frames 12 are slidably engaged on the frame 1. A separator 4 is slidably connected to the adjusting frames 12. A rotary drive device 13 is fixedly installed on the frame 1. The rotary drive device 13 can be a servo motor and can be connected to a signal processor. The two adjusting frames 12 are rotatably mounted with the same bidirectional threaded rod 14. The output end of the rotary drive device 13 is connected to the bidirectional threaded rod 14. By driving the bidirectional threaded rod 14 to rotate through the rotary drive device 13, the two adjusting frames 12 can be moved closer to each other. The separator 4 is slidably connected to the adjusting frames 12, so it can be manually moved to a position closer to the center for operation. The adjusting frames 12 are inclined in the direction from which the bolts are fed, so the bolts can be guided to a position closer to the center.

[0016] In some embodiments, to prevent the partition frame 4 from sliding on the adjusting frame 12 due to vibration, a friction pad 15 is fixedly installed on the partition frame 4, and the friction pad 15 abuts against the adjusting frame 12. The friction pad 15 can generate a friction effect with the adjusting frame 12, making the partition frame 4 less prone to sliding. Moreover, the friction pad 15 is positioned high, so the high-temperature bolts on the inclined conveyor 3 will not have a significant impact on it.

[0017] In some embodiments, to protect the linear actuator 2 9, a fixed connecting rod 16 is fixedly installed at the output end of the linear actuator 2 9, and a pressure plate 10 is installed at the bottom of the connecting rod 16. Therefore, the connecting rod 16 can bring the pressure plate 10 into the quenching tank 2, while the linear actuator 2 9 does not need its output end to directly extend into the quenching tank 2. When it contracts, it will bring the quenching liquid back, which may lead to unstable expansion and contraction.

[0018] In some embodiments, to further protect the linear actuator 9, a limiting rod 17 is fixedly installed on the connecting rod 16, and a slot 18 is provided on the frame 1 for the limiting rod 17 to be inserted. When the linear actuator 9 is extended for operation, the limiting rod 17 on the connecting rod 16 can be engaged in the slot 18 at the end of the entire stroke, so that the force of the inclined conveyor 3 driving the pressure plate 10 through the bolts will not affect the linear actuator 9.

[0019] In some embodiments, to facilitate the operation of the pressure plate 10, a guide shaft 19 is rotatably mounted inside the quenching tank 2, and the guide shaft 19 contacts the upper surface of the inclined conveyor 3. The guide shaft 19 bends the upper surface of the inclined conveyor 3 and forms a flat surface at one end inside the quenching tank 2, so that the pressure plate 10 can limit the bolts.

[0020] The fixed connection and rotating installation in the above embodiments can all be achieved by welding, screw fasteners and other forms in the prior art, and the rotating installation can be achieved by bearings, circular rotating blocks and circular grooves. All of the above components are standard parts, and those that are not standard parts can also be specially customized, so the inventor will not elaborate further.

[0021] 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.

[0022] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. 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.
