Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tempering devices, and in particular to a uniform tempering device for fastener heat treatment. Background Technology
[0002] In manufacturing, the quality of fasteners is crucial to the safety and stability of mechanical structures and equipment. To ensure the reliability of fasteners under harsh working environments such as high loads, high temperatures, and corrosion, heat treatment processes play a vital role. Among these processes, tempering is an important post-quenching treatment. Tempering effectively eliminates internal stresses generated during quenching, reduces hardness, and increases toughness, thereby achieving an optimal balance of mechanical properties in the metal material.
[0003] However, when using a uniform tempering device for fastener heat treatment, sometimes the heating tube inside the device may become damaged due to long-term use and need to be replaced. This can be inconvenient to disassemble and reassemble, requiring more time and affecting the use of the device. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a device for uniform tempering of fasteners during heat treatment.
[0005] This utility model is achieved by the following technical solution: a uniform tempering device for heat treatment of fasteners, comprising a limiting mechanism, a heating mechanism and a protective mechanism, wherein the limiting mechanism is located at the lower end of the heating mechanism and the heating mechanism is located inside the protective mechanism;
[0006] The limiting mechanism includes a lifting plate, a threaded rod threadedly connected to the inner wall of the lifting plate, a motor fixedly connected to the lower end of the threaded rod, a sliding block slidably connected to the inner wall of the lifting plate, a connecting rod rotatably connected to the inner wall of the sliding block, a first rotating shaft rotatably connected to the inner side of the connecting rod, a locking block rotatably connected to the surface of the connecting rod, a second rotating shaft rotatably connected to the inner wall of the locking block, and four sliding blocks symmetrically distributed with the threaded rod as the midpoint.
[0007] The above technical solution utilizes the lifting plate to drive the connecting rod to rotate, thereby driving the locking block to rotate. This design enables convenient disassembly and assembly of the heating tube when it is damaged and requires maintenance, making subsequent maintenance of the device more convenient.
[0008] As a further improvement to the above solution, the heating mechanism includes a first connecting frame, a protective frame fixedly connected to the lower end of the first connecting frame, a second connecting frame fixedly connected to the lower end of the protective frame, a heating tube fixedly connected to the inner wall of the protective frame, a connecting groove formed on the surface of the protective frame, a handle fixedly connected to the upper end of the first connecting frame, the heating tube located between the first connecting frame and the second connecting frame, and the surface of the locking block engaging with the inner wall of the connecting groove.
[0009] The above technical solution, which uses components such as the first connecting frame and the protective frame to drive the heating tube to be disassembled and assembled inside the protective shell, makes subsequent maintenance of the heating tube more convenient and improves the overall practicality of the device.
[0010] As a further improvement to the above solution, the protective mechanism includes a protective shell, a supporting leg fixedly connected to the lower end of the protective shell, a sealing door rotatably connected to the upper end of the protective shell, a protective partition fixedly connected to the inner wall of the protective shell, a protective frame slidably connected to the surface of the first connecting frame, the protective frame being located between the protective shell and the protective partition, a motor fixedly connected to the inner wall of the protective shell, a threaded rod rotatably connected to the inner wall of the protective shell, a first rotating shaft fixedly connected to the inner wall of the protective shell, and a second rotating shaft fixedly connected to the inner wall of the protective shell.
[0011] The above technical solutions provide protection and support for the internal components of the device, making the subsequent use of the device more stable.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This utility model employs a limiting mechanism: When an external power source is connected, the motor is started to rotate, which in turn drives the threaded rod to rotate. Simultaneously, a lifting plate on its surface, constrained by surrounding connecting rods, descends along the direction of the threaded rod, causing the connecting rod to rotate around a first pivot. Simultaneously, as it descends, a sliding block slides on the inner wall of the lifting plate, driving the other end of the connecting rod to rise. At the same time, a locking block connected to the lifting plate rotates outwards under the constraint of a second pivot, separating from the inner wall of the connecting groove. This releases the overall limiting effect on the heating mechanism, facilitating subsequent disassembly and assembly. The design, which uses the lifting of the lifting plate to drive the connecting rod and thus the locking block, enables convenient disassembly and assembly when the heating element is damaged and requires maintenance, making subsequent maintenance of the device more convenient.
[0014] This utility model incorporates a heating mechanism: after releasing the limiting position on the connecting groove, the sealing door is rotated to open it, and then the handle is pulled to slide out the first connecting frame and protective frame, etc., so as to maintain and replace the heating tube inside. The design of using the first connecting frame and protective frame to move the heating tube inside the protective shell for disassembly and assembly makes subsequent maintenance of the heating tube more convenient and improves the overall practicality of the device.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0023] Example:
[0024] Please combine Figure 1-5 The fastener heat treatment uniform tempering device of this embodiment includes a limiting mechanism 1, a heating mechanism 2 and a protective mechanism 3. The limiting mechanism 1 is located at the lower end of the heating mechanism 2, and the heating mechanism 2 is located inside the protective mechanism 3.
[0025] The limiting mechanism 1 includes a lifting plate 101. A threaded rod 102 is threadedly connected to the inner wall of the lifting plate 101. A motor 103 is fixedly connected to the lower end of the threaded rod 102. A sliding block 104 is slidably connected to the inner wall of the lifting plate 101. A connecting rod 105 is rotatably connected to the inner wall of the sliding block 104. A first rotating shaft 106 is rotatably connected to the inner side of the connecting rod 105. A locking block 107 is rotatably connected to the surface of the connecting rod 105. A second rotating shaft 108 is rotatably connected to the inner wall of the locking block 107. The design of using the lifting of the lifting plate 101 to drive the connecting rod 105 to rotate, thereby driving the locking block 107 to rotate, realizes the purpose of convenient disassembly and assembly when the heating tube 204 is damaged and needs maintenance, making subsequent maintenance of the device more convenient.
[0026] There are four sliding blocks 104, which are symmetrically distributed with the threaded rod 102 as the midpoint.
[0027] The heating mechanism 2 includes a first connecting frame 201, a protective frame 202 fixedly connected to the lower end of the first connecting frame 201, a second connecting frame 203 fixedly connected to the lower end of the protective frame 202, a heating tube 204 fixedly connected to the inner wall of the protective frame 202, a connecting groove 205 opened on the surface of the protective frame 202, and a handle 206 fixedly connected to the upper end of the first connecting frame 201. The design of using the first connecting frame 201 and the protective frame 202 to drive the heating tube 204 to be disassembled and assembled inside the protective shell 301 makes subsequent maintenance of the heating tube 204 more convenient and improves the overall practicality of the device.
[0028] The heating tube 204 is located between the first connecting frame 201 and the second connecting frame 203, and the surface of the locking block 107 is engaged with the inner wall of the connecting groove 205.
[0029] The protective mechanism 3 includes a protective shell 301, with a support leg 302 fixedly connected to the lower end of the protective shell 301, a sealing door 303 rotatably connected to the upper end of the protective shell 301, and a protective partition 304 fixedly connected to the inner wall of the protective shell 301.
[0030] The inner wall of the protective frame 202 is slidably connected to the surface of the first connecting frame 201, and the protective frame 202 is located between the protective shell 301 and the protective partition 304.

[0032] The implementation principle of the uniform tempering device for fastener heat treatment in this embodiment is as follows: When using the device and disassembling and maintaining its heating tube 204, first connect the external power supply to start the motor 103 to rotate, thereby driving the threaded rod 102 to rotate. While the threaded rod 102 rotates, the lifting plate 101 on its surface descends along the direction of the threaded rod 102 under the restriction of the surrounding connecting rods 105, thereby driving the connecting rod 105 to rotate around the first rotating shaft 106 as the fulcrum. At the same time, while descending, the sliding block 104 slides on the inner wall of the lifting plate 101, thereby driving the other end of the connecting rod 105 to rise. Meanwhile, the locking block 107 connected to it moves along the second rotating shaft 106. Under the restriction of 08, it rotates outward to separate from the inner wall of the connecting groove 205, thereby releasing the restriction on the entire heating mechanism 2, so as to facilitate subsequent disassembly and assembly. The design of using the lifting plate 101 to drive the connecting rod 105 to rotate, thereby driving the locking block 107 to rotate, realizes the purpose of convenient disassembly and assembly when the heating tube 204 is damaged and needs maintenance, making subsequent maintenance of the device more convenient. After releasing the restriction on the connecting groove 205, rotate the sealing door 303 to open it, and then pull the handle 206 to drive the first connecting frame 201 and the protective frame 202 and other parts to slide out, so as to maintain and replace the heating tube 204 inside. The design of using the first connecting frame 201 and the protective frame 202 and other parts to drive the heating tube 204 to be disassembled and assembled inside the protective shell 301 realizes the purpose of making subsequent maintenance of the heating tube 204 more convenient, improving the overall practicality of the device.
