Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat treatment furnace technology, and in particular to a heat treatment furnace with a limiting buffer device. Background Technology
[0002] A heat treatment furnace is a device used to heat treat metallic materials. By controlling the heating, holding, and cooling processes, it alters the microstructure and properties of the metallic materials. Common types include resistance furnaces, vacuum furnaces, and gas furnaces, and they are widely used in industries such as machinery manufacturing, aerospace, and automobiles.
[0003] A heat treatment furnace typically consists of a furnace body with internal tracks on which a trolley is slidably connected to carry the material to be treated. However, existing heat treatment furnaces have the following problems during use: when the trolley moves to the end of the tracks, due to inertia, the trolley will generate a large impact force on the inner wall of the furnace body. This impact force will not only damage the inner wall of the furnace body, but also damage other internal structures, affecting the service life of the equipment. Therefore, we propose a heat treatment furnace with a limit buffer device. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a heat treatment furnace with a limiting buffer device.
[0005] This utility model is achieved by the following technical solution: a heat treatment furnace with a limiting buffer device, including a heat treatment furnace body, a track fixedly connected to the inner wall of the heat treatment furnace body, a trolley slidably connected to the surface of the track, a buffer assembly provided at the left end of the trolley, and a baffle fixedly connected to the bottom of the trolley.
[0006] The buffer assembly includes a mounting plate, a guide rod fixedly connected to the inner wall of the mounting plate, a first buffer spring sleeved on the surface of the guide rod, a sliding seat slidably connected to the surface of the guide rod, a first hinge seat fixedly connected to the left end of the sliding seat, a movable plate hinged to the inner wall of the first hinge seat, a second hinge seat hinged to the end of the movable plate away from the first hinge seat, a fixed plate fixedly connected to the left end of the second hinge seat, and a fireproof cloth fixedly connected to the left end of the fixed plate.
[0007] Through the above technical solution, the fireproof cloth comes into contact with the inner wall of the heat treatment furnace body, avoiding damage to the inner wall of the heat treatment furnace body caused by hard collisions. At the same time, the fixed plate moves, causing the movable plate to rotate around the hinge point of the first hinge seat and the second hinge seat, pushing the two sliding seats to move away from each other and compressing the first buffer spring. The compression of the first buffer spring absorbs the impact energy, effectively reducing the impact force of the trolley, preventing the trolley from moving too fast and causing damage to the internal structure of the heat treatment furnace body, and extending the service life of the heat treatment furnace body. The fireproof cloth is made of silicon dioxide material, which can be used for a long time in high-temperature environments without aging.
[0008] As a further improvement to the above solution, the mounting plate is bolted to the left end of the trolley, and there are two guide rods, which are symmetrically distributed with the mounting plate as the center.
[0009] With the above technical solution, since the mounting plate is bolted to the trolley, it is easy to disassemble and replace it later.
[0010] As a further improvement to the above solution, one end of the first buffer spring is fixedly connected to the surface of the mounting plate.
[0011] The above technical solution improves the buffering effect by setting the number of first buffer springs to four.
[0012] As a further improvement to the above solution, the end of the first buffer spring away from the mounting plate contacts the surface of the sliding seat.
[0013] With the above technical solution, when the fixed plate is not in contact with the inner wall of the heat treatment furnace, the elastic reset of the first buffer spring pushes the sliding seat to move closer to each other, so that the movable plate rotates and pushes the fixed plate to move, so that the fixed plate is reset and can be used again later.
[0014] As a further improvement to the above solution, two of each of the sliding seat, the first hinge seat, the movable plate, and the second hinge seat are provided.
[0015] As a further improvement to the above solution, a damper is fixedly connected to one end of the track, and a second buffer spring is sleeved on the surface of the damper.
[0016] With the above technical solution, when the trolley moves outward, the baffle at the bottom of the trolley will contact the second buffer spring. The combined use of the damper and the second buffer spring absorbs the impact energy, improves the buffering effect, and avoids the trolley's track wheels from colliding with the end of the track, thus preventing track damage.
[0017] As a further improvement to the above solution, the right end of the second buffer spring is fixedly connected to the surface of the track.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] This invention incorporates a buffer assembly. Specifically, the fireproof cloth contacts the inner wall of the heat treatment furnace body, preventing damage to the inner wall of the furnace body from hard impacts. Simultaneously, the fixed plate moves, causing the movable plate to rotate around the hinge point of the first and second hinge seats. This pushes the two sliding seats away from each other and compresses the first buffer spring. The compression of the first buffer spring absorbs the impact energy, effectively reducing the impact force of the trolley and preventing damage to the internal structure of the heat treatment furnace body caused by excessively rapid trolley movement, thus extending the service life of the heat treatment furnace body.
[0020] This utility model incorporates a baffle, a damper, and a second buffer spring. Specifically, when the trolley moves outward, the baffle first contacts the second buffer spring. The combined use of the damper and the second buffer spring absorbs impact energy, improving the buffering effect and preventing the trolley's track wheels from colliding with the end of the track, thus avoiding track damage and extending the track's service life.

[0028] 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.
[0029] Example:
[0030] Please combine Figure 1-5 A heat treatment furnace with a limiting buffer device in this embodiment includes a heat treatment furnace body 1, a rail 2 fixedly connected to the inner wall of the heat treatment furnace body 1, a trolley 3 slidably connected to the surface of the rail 2, a buffer assembly 4 provided at the left end of the trolley 3, and a baffle 5 fixedly connected to the bottom of the trolley 3.
[0031] The buffer assembly 4 includes a mounting plate 401. A guide rod 402 is fixedly connected to the inner wall of the mounting plate 401. A first buffer spring 403 is sleeved on the surface of the guide rod 402. A sliding seat 404 is slidably connected to the surface of the guide rod 402. A first hinge seat 405 is fixedly connected to the left end of the sliding seat 404. A movable plate 406 is hinged to the inner wall of the first hinge seat 405. A second hinge seat 407 is hinged to the end of the movable plate 406 away from the first hinge seat 405. A fixed plate 408 is fixedly connected to the left end of the second hinge seat 407. A fireproof cloth 409 is fixedly connected to the left end of the fixed plate 408. When the trolley 3 moves with the heat treatment furnace... When the inner wall of the body 1 comes into contact, the fireproof cloth 409 first contacts the inner wall of the heat treatment furnace body 1 to avoid damage to the inner wall of the heat treatment furnace body 1 caused by hard collision. At the same time, the fixed plate 408 moves, causing the movable plate 406 to rotate around the hinge point of the first hinge seat 405 and the second hinge seat 407, pushing the two sliding seats 404 to move away from each other, and squeezing the first buffer spring 403. The compression of the first buffer spring 403 absorbs the impact energy, effectively reducing the impact force of the trolley 3, preventing the trolley 3 from moving too fast and causing damage to the internal structure of the heat treatment furnace body 1, and extending the service life of the heat treatment furnace body 1.
[0032] Mounting plate 401 is bolted to the left end of trolley 3. There are two guide rods 402, which are symmetrically distributed around mounting plate 401. The guide rods 402 guide the sliding seat 404 and prevent the sliding seat 404 from deviating during movement.
[0033] One end of the first buffer spring 403 is fixedly connected to the surface of the mounting plate 401.
[0034] The end of the first buffer spring 403 away from the mounting plate 401 contacts the surface of the sliding seat 404.
[0035] There are two of each of the following: sliding seat 404, first hinge seat 405, movable plate 406, and second hinge seat 407.
[0036] A damper 6 is fixedly connected to one end of the track 2. A second buffer spring 7 is sleeved on the surface of the damper 6. When the trolley 3 moves outward, the baffle 5 will first contact the second buffer spring 7. The shock energy is absorbed by the cooperation of the damper 6 and the second buffer spring 7, which improves the buffering effect, avoids the track wheel of the trolley 3 from colliding with the end of the track 2, and prevents the track 2 from being damaged, thus extending the service life of the track 2.
[0037] The right end of the second buffer spring 7 is fixedly connected to the surface of the track 2.
[0038] The implementation principle of a heat treatment furnace with a limiting buffer device in this embodiment is as follows: During use, the trolley 3 moves along the track 2 to feed the material to be processed into the interior of the heat treatment furnace body 1. When the trolley 3 moves and contacts the inner wall of the heat treatment furnace body 1, the fireproof cloth 409 first contacts the inner wall of the heat treatment furnace body 1 to avoid damage to the inner wall of the heat treatment furnace body 1 due to hard collision. At the same time, the fixed plate 408 moves, causing the movable plate 406 to rotate around the hinge point of the first hinge seat 405 and the second hinge seat 407, pushing the two sliding seats 404 to move away from each other. Furthermore, the compression of the first buffer spring 403 absorbs the impact energy, effectively reducing the impact force of the trolley 3 and preventing the trolley 3 from moving too fast and causing damage to the internal structure of the heat treatment furnace body 1, thus extending the service life of the heat treatment furnace body 1. When the trolley 3 moves outward, the baffle 5 will first contact the second buffer spring 7. Through the combined use of the damper 6 and the second buffer spring 7, the impact energy is absorbed, improving the buffering effect and preventing the track wheel of the trolley 3 from colliding with the end of the track 2, which would cause damage to the track 2 and extend the service life of the track 2.
[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
