Description

Technical Field

[0001] This utility model relates to the field of heat treatment equipment technology, and in particular to a spring-loaded heat treatment preheating device. Background Technology

[0002] Spring clamps are a common type of mechanical fastener, also known as clamps, grips, or hose clamps. They are widely used in many fields due to their simple structure, convenient installation, and good fastening effect.

[0003] As a commonly used connecting component in mechanical parts, the preheating process during heat treatment has a significant impact on the subsequent processing quality and performance of spring clips. Proper preheating can reduce thermal stress during heat treatment, prevent defects such as cracks and deformation, and improve the strength, toughness, and other mechanical properties of the spring clips. However, existing spring clip preheating devices use a fixed heating source, such as a heating pipe fixed to one side wall of the preheating chamber. This unidirectional heating method allows the side of the spring clip closest to the heating source to absorb heat quickly, while the side farther from the heating source experiences slow heat transfer. This results in uneven heating of the spring clip during preheating, leading to deformation and severely affecting its quality and subsequent performance. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a spring-loaded heat treatment preheating device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A preheating device for heat treatment of elastic bands includes a base 1, a preheating box 2 fixedly installed on the upper surface of the base 1, guide frames 3 fixedly installed on the inner walls of both sides of the preheating box 2, sliders 5 slidably installed inside the two guide frames 3 via a sliding mechanism, and a support plate 6 fixedly connected to the ends of the two sliders 5. A placement plate 8 is fixedly installed on the upper surface of the support plate 6 via a support rod 7. A support plate 9 is fixedly installed on the upper surface of the base 1, and a movable plate 11 is fixedly connected to the outer wall of the support plate 9 via a first telescopic mechanism. The inner wall of the movable plate 11 is fixedly connected to the outer wall of the support plate 6 via a connecting mechanism. A ball bearing 13 is fixedly installed on the upper end face of the preheating box 2 through the installation opening. A rotating shaft 14 is fixedly installed on the inner ring of the ball bearing 13. A connecting frame 15 is fixedly installed on the outer wall of the rotating shaft 14. Mounting frames 17 are fixedly connected to both sides of the connecting frame 15 through the second telescopic mechanism. Infrared radiation heating tubes 18 are fixedly installed inside the two mounting frames 17. A servo motor 20 is fixedly installed on the upper end face of the preheating box 2 through the support frame 19. A pulley 21 is fixedly installed on both the output shaft of the servo motor 20 and the outer wall of the rotating shaft 14. The two pulleys 21 are connected by a belt for transmission.

[0023] Furthermore, the tray 6 is made of high-strength aluminum alloy, which reduces the overall weight while ensuring structural strength. The surface of the placement plate 8 is coated with a high-temperature resistant and anti-slip coating to prevent the spring clip from sliding during preheating and to ensure accurate heating position.

[0024] The sliding mechanism includes a slide rod 4 fixedly installed inside the guide frame 3, which slides through the slider 5.

[0025] Furthermore, the outer wall of the slide bar 4 is provided with a wear-resistant coating, which can reduce the frictional resistance when the slider 5 slides and extend the service life of the slider 5.

[0026] The first telescopic mechanism includes a first electric push rod 10 fixedly installed on the outer wall of the support plate 9, and the telescopic end of the first electric push rod 10 is fixedly connected to the inner wall of the movable plate 11.

[0027] Furthermore, the first electric actuator 10 is a servo electric actuator with high-precision position control capability, which can accurately control the moving distance of the moving plate 11. The housing of the first electric actuator 10 is made of stainless steel, which has good corrosion resistance and is suitable for various working environments.

[0028] The connecting mechanism includes a connecting rod 12 fixedly installed on the inner wall of the movable plate 11. The outer wall of the preheating box 2 has a movable opening that cooperates with the connecting rod 12. The end of the connecting rod 12 is fixedly connected to the outer wall of the support plate 6.

[0029] Furthermore, the connecting rod 12 is made of solid steel, which has high strength and rigidity and can reliably transmit power.

[0030] The second telescopic mechanism includes a second electric push rod 16 fixedly installed on the inner wall of the connecting frame 15, and the telescopic end of the second electric push rod 16 is fixedly connected to the outer wall of the mounting frame 17.

[0031] Furthermore, the second electric actuator 16 is a miniature electric actuator, which is small in size and has a large thrust, making it suitable for use in limited spaces.

[0032] Furthermore, the connecting frame 15 adopts a frame structure design, which reduces weight while ensuring structural strength. The mounting frame 17 is a semi-enclosed design, which can prevent the heat generated by the infrared radiation heating tube 18 from accumulating during long-term operation.

[0033] A controller 22 is fixedly installed on the outer wall of the preheating box 2. The controller 22 is electrically connected to the first electric push rod 10, two second electric push rods 16, two infrared radiation heating tubes 18, and servo motor 20.

[0034] Furthermore, the controller 22 adopts a PLC programmable controller, which has powerful data processing capabilities and stable working performance. The operation panel of the controller 22 is equipped with a touch screen, which can intuitively display the working status and parameters of the device, and can be operated and set through the touch screen.

[0035] When this utility model is in use, the controller 22 can control the first electric push rod 10, the two second electric push rods 16, the two infrared radiation heating tubes 18, and the servo motor 20. Before preheating the spring band, the first electric push rod 10 can extend outward and drive the tray 6 to slide outward along the slide rod 4 in the guide frame 3 through the connecting rod 12, so that the placement plate 8 on the upper surface of the tray 6 moves out of the preheating box 2. At this time, the operator can easily place the spring band to be preheated on the placement plate 8 to complete the spring band loading step. After the spring band is placed, the operator issues a command through the controller 22, the first electric push rod 10 retracts, and drives the placement plate 8 and the spring band to smoothly enter the preheating box 2. Then, according to the specific size and shape of the spring band, the controller 22 starts the two second electric push rods 16. The telescopic end of the second electric push rod 16 pushes the mounting frame 17 to precisely adjust the distance between the infrared radiation heating tube 18 and the spring band in the mounting frame 17, ensuring that the infrared radiation heating tube 18 is in a suitable heating position, thus ensuring uniform heating.

[0036] Once the position of the infrared radiation heating tube 18 is adjusted, the controller 22 starts the servo motor 20 and the two infrared radiation heating tubes 18. The output shaft of the servo motor 20 drives the pulley 21 to rotate. Through belt transmission, the rotating shaft 14 starts to rotate, and the connecting frame 15 fixed on the outer wall of the rotating shaft 14 rotates accordingly. This causes the mounting frames 17 on both sides of the connecting frame 15 and the infrared radiation heating tubes 18 to move in a circular motion around the spring band. At the same time, the infrared radiation heating tubes 18 continuously emit infrared radiation heat, heating the spring band from multiple angles to achieve uniform heating of the spring band. During the preheating process, the controller 22 can also monitor and adjust the heating power of the infrared radiation heating tubes 18 and the speed of the servo motor 20 in real time according to the preset preheating temperature and time parameters to ensure that the preheating process is stable and efficient. When the preset preheating time and temperature are reached, the controller 22 controls the infrared radiation heating tubes 18 to stop heating and the servo motor 20 to stop running. Then, the controller controls the first electric push rod 10 to extend, moving the placement plate 8 and the preheated spring band out of the preheating box 2 to facilitate the operator to carry out subsequent heat treatment procedures.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
