Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of steel bar processing technology, and more specifically, to an auxiliary heating device for heat treatment of steel bars. Background Technology
[0002] Steel bars are common steel products. According to the production process, they can be divided into hot-rolled, cold-drawn, and forged types. According to the shape, they include round bars, square bars, hexagonal bars, and flat bars. They have high strength, good toughness, and some types are highly corrosion resistant. They are also easy to process and can be made into various parts through welding, forging and other processes. They are widely used in steel reinforcement in the construction field, parts in machinery manufacturing, equipment in petrochemical industry and structural components in aerospace, etc., and are an indispensable basic material in industry and construction.
[0003] Currently, when processing steel bars, operators need to perform heat treatment. Although the existing heating devices can achieve the basic functions of assisting in heating the steel bars and clamping and fixing them, they have obvious shortcomings in actual use. Before heat treatment, the steel bars need to be transported into the heating hood by guide wheels. During this process, the operator must first use appropriate tools to clamp the steel bars and then laboriously adjust the steel bars to align with the two guide wheels before they can be transported into the heating hood for fixing. This operation method not only increases the operator's working time but also reduces the overall work efficiency. Therefore, it needs to be improved. Utility Model Content
[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide an auxiliary heating device for heat treatment of steel bars, which solves the technical problem of inconvenient transportation in related technologies.
[0005] According to one aspect, at least one embodiment of this disclosure provides an auxiliary heating device for heat treatment of steel bars, including a workbench, a protective cover fixedly connected to the top of the front of the workbench, a drive motor fixedly installed inside the protective cover, a rotating shaft fixedly sleeved at the other end of the output shaft of the drive motor, the other end of the rotating shaft passing through the protective cover and extending to the outside of the back of the protective cover, and a rotating rod fixedly sleeved on its outer surface, the outer surface of the rotating shaft being movably connected to the inside of the protective cover, a round shaft movably connected inside the rotating rod, the other end of the round shaft passing through the rotating rod and extending to the outside of the back of the rotating rod and fixedly connected to a heating cover, and an exhaust hole being provided at the top of the left front of the heating cover.
[0006] As a preferred embodiment of this utility model, heating plates are fixedly installed inside the top of the heating cover and inside the front and rear sides, and a connecting block is fixedly connected to the bottom right side of the heating cover.
[0007] As a preferred technical solution of this utility model, a long rod is fixedly connected to the top of the right side of the workbench. The top of the long rod passes through the connecting block and extends to the outside of the top of the connecting block, and its outer surface is movably connected to the inside of the connecting block.
[0008] As a preferred embodiment of this utility model, movable blocks are movably connected to the left and right sides of the top of the workbench in the front and back directions, and high-temperature resistant clamping blocks are fixedly installed on the top of the movable blocks.
[0009] As a preferred technical solution of this utility model, heating plates are fixedly installed inside both the upper and lower ends of the high-temperature resistant clamping block, and a guide block is fixedly connected to the bottom end of the movable block. The bottom end of the guide block passes through the workbench and extends to the outside of the top of the inner surface of the workbench, and the outer surface is movably connected to the inside of the top of the workbench.
[0010] As a preferred embodiment of this utility model, the bottom end of the guide block is fixedly connected to a long plate, and there are two long plates. The bottom ends of the two long plates are movably connected to the bottom end of the inner surface of the workbench.
[0011] As a preferred embodiment of this utility model, springs are fixedly connected to the left and right sides of the back surfaces of the two long plates, and the other end of the springs is fixedly connected to the inner surface of the workbench.
[0012] As a preferred embodiment of this utility model, a servo motor is fixedly installed on the right side of the bottom end of the inner surface of the workbench, and a rotating shaft is fixedly sleeved on the other end of the output shaft of the servo motor.
[0013] As a preferred embodiment of this utility model, a convex block is fixedly sleeved on the bottom end of the outer surface of the rotating shaft, and the bottom end of the convex block is movably connected to the bottom end of the inner surface of the worktable.
[0014] As a preferred embodiment of this utility model, table legs are fixedly connected to the four corners of the bottom of the workbench, and the number of table legs is four, with the four table legs having the same size.
[0015] The beneficial effects of the embodiments disclosed herein are as follows:
[0016] 1. In this disclosure, by setting up a drive motor, a rotating shaft, a rotating rod, and a round shaft, when the operator starts the drive motor, the rotating shaft and the rotating rod will rotate, thereby causing the inner surface of the rotating rod to squeeze and push the outer surface of the round shaft, which in turn causes the round shaft to drive the heating cover to move upward, thereby increasing the distance between the bottom end of the heating cover and the top end of the worktable, making the operating space at the top of the worktable completely open, and allowing the operator to quickly clamp and fix the steel bar and perform heat treatment operations on it.
[0017] 2. In this disclosure, by setting up a high-temperature resistant clamping block, a servo motor, a rotating shaft, and a convex block, the operator starts the servo motor, which will cause the rotating shaft and the convex block to rotate. This will cause the outer surface of the convex block to squeeze and push the opposite surfaces of the two long plates, thereby causing the two long plates to drive the four guide blocks, four movable blocks, and four high-temperature resistant clamping blocks to move in opposite directions. At this time, the four springs are compressed. This operation increases the distance between the four high-temperature resistant clamping blocks, allowing the operator to place steel bars of different diameters between the four high-temperature resistant clamping blocks.

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0028] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0029] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.
[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0032] like Figures 1-6As shown, it illustrates an auxiliary heating device for heat treatment of steel bars according to an embodiment of the present disclosure, including a workbench 1. A protective cover 2 is fixedly connected to the top of the front of the workbench 1. A drive motor 3 is fixedly installed inside the protective cover 2. A rotating shaft 4 is fixedly sleeved at the other end of the output shaft of the drive motor 3. The other end of the rotating shaft 4 passes through the protective cover 2 and extends to the outside of the back of the protective cover 2, and a rotating rod 5 is fixedly sleeved on its outer surface. The outer surface of the rotating shaft 4 is movably connected to the inside of the protective cover 2. A round shaft 6 is movably connected inside the rotating rod 5. The other end of the round shaft 6 passes through the rotating rod 5 and extends to the outside of the back of the rotating rod 5, and a heating cover 7 is fixedly connected to it. An exhaust hole 8 is opened at the top of the left front of the heating cover 7.
[0033] Due to the design of the protective cover 2, the drive motor 3 can be well protected. Due to the design of the exhaust port 8, the hot air inside the heating cover 7 can be discharged to the outside, thus preventing the hot air inside the heating cover 7 from exploding due to the inability to be discharged.
[0034] In some examples, heating plates 9 are fixedly installed inside the top of the heating cover 7 and inside the front and rear sides, and a connecting block 10 is fixedly connected to the bottom right side of the heating cover 7.
[0035] The design of the three heating plates 9 enables heat treatment of the iron rods inside the heating shroud 7.
[0036] In some examples, a long rod 11 is fixedly connected to the top right side of the workbench 1. The top end of the long rod 11 passes through the connecting block 10 and extends to the outside of the top end of the connecting block 10, and its outer surface is movably connected to the inside of the connecting block 10.
[0037] Due to the design of the long rod 11, the movement of the heating cover 7 can be well guided.
[0038] In some examples, movable blocks 12 are movably connected to the left and right sides of the top of the workbench 1 in the front and back directions, and high-temperature resistant clamping blocks 13 are fixedly installed on the top of the movable blocks 12.
[0039] The design of the four high-temperature resistant clamping blocks 13 enables the clamping and fixing of steel bars of different sizes.
[0040] In some examples, heating plates 14 are fixedly installed inside both the upper and lower ends of the high-temperature resistant clamping block 13, and a guide block 15 is fixedly connected to the bottom end of the movable block 12. The bottom end of the guide block 15 passes through the workbench 1 and extends to the outside of the top of the inner surface of the workbench 1, and the outer surface is movably connected to the inside of the top of the workbench 1.
[0041] The design of eight heating plates 14 enables the preheating of four high-temperature resistant clamping blocks 13, thereby enabling auxiliary heating of the steel bar.
[0042] In some examples, the bottom end of the guide block 15 is fixedly connected to a long plate 16, and there are two long plates 16. The bottom ends of the two long plates 16 are movably connected to the bottom end of the inner surface of the worktable 1.
[0043] Since the connection between the top ends of the two long plates 16 and the bottom ends of the four guide blocks 15 is fixed, when the two long plates 16 move, they will drive the two guide blocks 15 to move together.
[0044] In some examples, springs 17 are fixedly connected to the left and right sides of the back of the two long plates 16, and the other end of the springs 17 is fixedly connected to the inner surface of the worktable 1.
[0045] The design of the four springs 17 enables a good restoring effect on the movement of the two long plates 16.
[0046] In some examples, a servo motor 18 is fixedly installed on the right side of the bottom end of the inner surface of the worktable 1, and a rotating shaft 19 is fixedly sleeved on the other end of the output shaft of the servo motor 18.
[0047] Because the servo motor 18 has a self-locking function, it can maintain the stability of the rotating shaft 19 even when it is powered off.
[0048] In some examples, a protruding block 20 is fixedly sleeved on the bottom end of the outer surface of the rotating shaft 19, and the bottom end of the protruding block 20 is movably connected to the bottom end of the inner surface of the worktable 1.
[0049] Since the bottom end of the convex block 20 and the bottom end of the inner surface of the worktable 1 are both smooth, the frictional loss between the convex block 20 and the bottom end of the inner surface of the worktable 1 can be reduced when the convex block 20 rotates.
[0050] In some examples, table legs 21 are fixedly connected to the four corners of the bottom of the workbench 1. There are four table legs 21, and the four table legs 21 are the same size.
[0051] The design of the four table legs 21 provides excellent support for the workbench 1 as a whole.
[0052] Working principle and usage process of this utility model:
[0053] First, the operator operates eight heating plates 14, drive motor 3, and servo motor 18. The operation of the eight heating plates 14 causes them to conduct electricity and generate heat, thus preheating the four high-temperature clamping blocks 13. The operation of drive motor 3 causes the rotating shaft 4 and rotating rod 5 to rotate, thereby causing the inner surface of rotating rod 5 to press and push the outer surface of round shaft 6, which in turn causes round shaft 6 to drive the heating cover 7 to move upward, thus providing the operator with enough space to prepare for the subsequent clamping and fixing of steel bars. The operation of servo motor 18 causes the rotating shaft 19 and convex block 20 to rotate, thereby causing the outer surface of convex block 20 to press and push the opposite surfaces of two long plates 16, which in turn causes the two long plates 16 to drive the four guide blocks 15, four movable blocks 12, and four high-temperature clamping blocks 13 to move in opposite directions. At this time, the four springs 17 will be in a compressed state, allowing the operator to place steel bars of different diameters between the four high-temperature clamping blocks 13.
[0054] Finally, the operator runs the servo motor 18 and drive motor 3 again. The operation of the servo motor 18 causes the rotating shaft 19 and the convex block 20 to return to their initial state. At this time, due to the restoring effect of the elastic force of the four springs 17, the two long plates 16 are pushed to move towards each other, so that the four high-temperature resistant clamping blocks 13 can clamp and fix the steel bar. The operation of the drive motor 3 causes the rotating shaft 4 and the rotating rod 5 to return to their initial state, so that the heating cover 7 moves downward and the bottom end coincides with the top end of the worktable 1. At this time, the operator starts the heating plate 9, which will make the heating plate 9 conductive and heated, so that the steel bar inside the heating cover 7 can be heat treated.
[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
