Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating furnace technology, and in particular to a round steel heating device. Background Technology
[0002] Round steel refers to solid, long steel bars with a circular cross-section. Its specifications are expressed by diameter in millimeters. Round steel is commonly used to manufacture machine parts, reinforcing bars, and other building and hardware accessories. According to the production process, round steel can be divided into hot-rolled round steel, forged round steel, and cold-drawn round steel. According to the carbon content, it can be divided into low-carbon steel, medium-carbon steel, and high-carbon steel. According to its use, it can be divided into carbon structural steel and carbon tool steel.
[0003] A round steel heating furnace is a device for heat treatment of round steel bars and round bars. It includes a furnace body and a worktable. The furnace body is equipped with electric heating or other heating equipment. The worktable is loaded with round steel bars from outside the furnace body and then enters the furnace body for heat treatment. However, most existing devices have certain defects. Because the lower part of the round steel bar is in contact with the worktable while the upper part is in contact with the air during heating, the round steel bar is heated unevenly, resulting in low heating efficiency. Therefore, a round steel heating device with uniform heating is needed. Utility Model Content
[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a round steel heating device that can solve the problem of uneven heating and low heating efficiency caused by the lower part of the round steel contacting the table surface and the upper part contacting the air during heating.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a round steel heating device, comprising a round steel heating box and a uniform heating mechanism. The uniform heating mechanism includes a first mounting plate, a drive motor, rotating shaft A, rotating shaft B, pulleys, a belt, rotating rollers, gears, and a heat-conducting box. The heat-conducting box is fixedly connected inside the round steel heating box. The first mounting plate is fixedly connected to the surface of the round steel heating box. The drive motor is fixedly connected to the surface of the first mounting plate. There are multiple rotating shafts A, all rotatably connected to the surface of the first mounting plate. The output shaft of the drive motor passes through the first mounting plate and is rotatably connected to the first mounting plate. One end of the rotating shaft A is fixedly connected to the output end of the drive motor. The number of gears is the same as that of the rotating shaft A, and all gears are fixedly sleeved on the outer surface of the rotating shaft A. There are multiple rotating shafts B, all rotatably connected to the surface of the first mounting plate. Pulleys are disposed on the outer surfaces of two adjacent rotating shafts A. A belt is disposed between two pulleys. There are multiple rotating rollers, each fixedly sleeved on the outer surface of each rotating shaft A and rotating shaft B.
[0006] Preferably, the interior of the heat-conducting box has multiple slots for placing round steel bars.
[0007] Preferably, a heating plate is fixedly connected inside the round steel heating box, and a heat conduction box is located on top of the heating plate.
[0008] Preferably, a heating box cover is rotatably connected to the surface of the round steel heating box, and a second mounting plate is fixedly connected inside the heating box cover.
[0009] Preferably, a plurality of springs are fixedly connected to the surface of the second mounting plate.
[0010] Preferably, a limiting plate is fixedly connected to the end of the spring away from the second mounting plate.
[0011] Preferably, the surface of the limiting plate has multiple grooves.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This round steel heating device has pulleys and belts on two adjacent rotating shafts A, enabling simultaneous rotation of both shafts A. Since each rotating shaft A is fixedly fitted with a gear, each shaft A rotates simultaneously, thus causing the rotating rollers fitted on the shafts A to rotate. Each round steel bar is in contact with one of the rotating rollers. The rotation of the rollers drives the round steel bar to rotate, activating the heating plate. The rotation of the round steel bar allows for uniform heating of its surface, ensuring more comprehensive heating and increasing work efficiency. This solves the problem of uneven heating and low heating efficiency caused by the lower part of the round steel bar contacting the table surface while the upper part is in contact with the air during heating.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0024] Please see Figure 1-4 This utility model provides a technical solution: a round steel heating device, including a round steel heating box 1 and a uniform heating mechanism. The uniform heating mechanism includes a first mounting plate 2, a drive motor 3, rotating shafts A4 and B5, pulleys 6, belts 7, rotating rollers 8, gears 9, and a heat-conducting box 10. The heat-conducting box 10 is fixedly connected inside the round steel heating box 1. The first mounting plate 2 is fixedly connected to the surface of the round steel heating box 1. The drive motor 3 is fixedly connected to the surface of the first mounting plate 2. There are multiple rotating shafts A4, all of which are rotatably connected to the surface of the first mounting plate 2. The output shaft of the drive motor 3 passes through the first mounting plate 2 and is rotatably connected to the first mounting plate 2. One end of the rotating shaft A4 is fixedly connected to the output end of the drive motor 3. The number of gears 9 is the same as that of the rotating shafts A4, and they are all fixedly sleeved on the outer surface of the rotating shafts A4. There are multiple rotating shafts B5, all of which are rotatably connected to the surface of the first mounting plate 2. The pulleys 6 are disposed on the outer surfaces of two adjacent rotating shafts A4. The belts 7 are disposed between two pulleys 6. There are multiple rotating rollers 8, which are respectively fixedly sleeved on the outer surfaces of each rotating shaft A4 and rotating shaft B5.
[0025] Furthermore, the heat-conducting box 10 has multiple placement slots 16 for placing round steel bars inside. A heating plate 17 is fixedly connected inside the round steel heating box 1, and the heat-conducting box 10 is located on top of the heating plate 17. The round steel bars are placed inside the placement slots 16 on the heat-conducting box 10, and the surface of the round steel bars is in contact with the surface of the rotating roller 8. In order to ensure that the round steel bars are heated evenly, the drive motor 3 is started to drive the rotating shaft A4 to rotate. Since pulleys 6 and belts 7 are provided on two adjacent rotating shafts A4, the two rotating shafts A4 can rotate simultaneously. Each rotating shaft A4 is fixedly fitted with a gear 9, so that each rotating shaft A4 rotates simultaneously. This causes the rotating roller 8 fitted on the rotating shaft A4 to rotate, and each round steel bar is in contact with one of the rotating rollers 8. The rotation of the rotating roller 8 drives the round steel bar to rotate, which activates the heating plate 17. Through the rotation of the round steel bar, its surface can be heated evenly, making it more comprehensively heated and improving work efficiency. This solves the problem of uneven heating and low heating efficiency caused by the lower part of the round steel bar contacting the table surface and the upper part contacting the air during heating.
[0026] Secondly, a heating box cover 11 is rotatably connected to the surface of the round steel heating box 1. A second mounting plate 12 is fixedly connected inside the heating box cover 11. Multiple springs 15 are fixedly connected to the surface of the second mounting plate 12. A limiting plate 13 is fixedly connected to the end of the spring 15 away from the second mounting plate 12. Multiple grooves 14 are opened on the surface of the limiting plate 13. When the round steel is placed on the placement groove 16 and the heating box cover 11 is closed, the grooves 14 on the limiting plate 13 will contact the upper part of the round steel, which can limit the round steel and prevent it from detaching from the surface of the rotating roller 8 when rotating, making the device more stable. The springs 15 set between the limiting plate 13 and the second mounting plate 12 can make the limiting plate 13 move to adapt to more types of round steel and increase the range of applications.
[0027] Working principle: The round steel is placed inside the placement slot 16 on the heat conduction box 10, with the surface of the round steel in contact with the surface of the rotating roller 8. To ensure uniform heating of the round steel, the drive motor 3 is started to drive the rotating shaft A4 to rotate. Since the two adjacent rotating shafts A4 are equipped with pulleys 6 and belts 7, the two rotating shafts A4 can rotate simultaneously. Since each rotating shaft A4 is fixedly fitted with a gear 9, each rotating shaft A4 will rotate simultaneously, thus causing the rotating roller 8 fitted on the rotating shaft A4 to rotate. Each round steel is in contact with one of the rotating rollers 8. The rotation of the rotating roller 8 drives the round steel to rotate. When the heating box cover 11 is closed, the groove 14 on the limiting plate 13 will contact the upper part of the round steel, which can limit the round steel and prevent it from detaching from the surface of the rotating roller 8 when rotating, making the device more stable. The spring 15 set between the limiting plate 13 and the second mounting plate 12 can allow the limiting plate 13 to move to accommodate more types of round steel. The heating plate 17 is started, and the surface of the round steel can be uniformly heated by the rotation of the round steel.
[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
