Description

Technical Field

[0001] This utility model belongs to the field of metal bar processing technology, and in particular relates to a heating furnace for metal bar processing. Background Technology

[0002] Metal bars are a type of metal material, mostly with a circular cross-section. They have a smooth surface, high dimensional accuracy, and high strength. They can be processed and heat-treated as needed. There are many types of metal bars, such as 304 stainless steel and 316 stainless steel, which have good corrosion resistance and high temperature resistance.

[0003] In the metal bar forming process, a heating furnace is needed to heat the metal bars. After heating, the atomic activity of the metal bars increases, making the material softer and improving its plasticity and formability. This allows them to be more easily forged into various complex shapes to meet different application requirements. When using a heating furnace to heat the metal bars, the metal bars are relatively heavy and need to be transported using a conveyor. During the long-term operation of the conveyor, wear or aging of the conveyor belt can reduce its friction and stability, potentially causing misalignment of the metal bars. Misalignment can lead to interruptions and delays in the conveying process, reducing production efficiency and potentially causing material accumulation or scattering, increasing safety hazards. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a heating furnace for processing metal rods that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: a heating furnace for processing metal rods includes a round rod heating furnace and a positioning assembly. The round rod heating furnace includes a furnace body and a conveyor table. The conveyor table is installed on the right side of the furnace body. The positioning assembly includes two side plates, two bottom plates, two top plates, and multiple positioning rods. The opposite ends of the two side plates are movably connected to the front and rear sides of the conveyor table, respectively. The opposite sides of the two bottom plates are fixedly connected to the opposite ends of the two side plates, respectively. The opposite sides of the two top plates are fixedly connected to the tops of the opposite ends of the two side plates, respectively. The bottoms of the two bottom plates are movably connected to the tops of the conveyor table, and the tops of the multiple positioning rods are fixedly connected to the bottoms of the two top plates, and the bottoms of the multiple positioning rods are fixedly connected to the tops of the two bottom plates.

[0006] The round bar heating furnace is used for heating metal bars.

[0007] The positioning component is used to limit the movement of the metal rod.

[0008] To prevent misalignment of the metal rods, preferably, support rods are movably connected to the bottom of the opposite ends of the two side plates. The left and right sides of the two support rods are fixedly connected to the left and right sides of the conveyor table surface, respectively. A synchronization component is provided on the rear side of the front support rod. The synchronization component drives the two side plates to move the same distance to opposite sides, so that the front limit rod and the rear limit rod move the same distance, thereby positioning the metal rods at the top center of the conveyor table.

[0009] To ensure that the two side plates move the same distance, preferably, the synchronization assembly includes a support plate, a synchronization gear, and two connecting frames. The front and rear sides of the support plate are fixedly connected to the bottom of the opposite ends of the two support rods, respectively. The bottom of the surface of the synchronization gear is movably connected to the interior of the support plate. The surface of the left connecting frame is movably connected to the interior of the rear support rod, and the surface of the right connecting frame is movably connected to the interior of the front support rod. The rear side of the left connecting frame is fixedly connected to the front side of the rear side plate, and the front side of the right connecting frame is fixedly connected to the rear side of the front side plate. The opposite ends of both connecting frames are meshed with the surfaces of the synchronization gear. When the front side plate moves, the front side plate drives the right connecting frame to move. During the movement of the right connecting frame, the synchronization gear drives the left connecting frame to move backward by the same distance, thereby causing the two side plates to move the same distance.

[0010] To prevent the two connecting frames from tilting and jamming with the synchronizing gear, preferably, two first sliding rods are fixedly connected to the rear side of the front support rod. The surfaces of the two first sliding rods are slidably connected to the left and right sides of the interior of the left connecting frame, respectively. Two second sliding rods are fixedly connected to the front side of the rear support rod. The surfaces of the two second sliding rods are slidably connected to the left and right sides of the interior of the right connecting frame, respectively. The first and second sliding rods support the two connecting frames, keeping them stable and preventing them from tilting.

[0011] In order to move the front side plate, preferably, a hydraulic cylinder is fixedly connected to the rear side of the front support rod, and the rear side of the output end of the hydraulic cylinder is fixedly connected to the rear side of the surface of the right connecting frame. The right connecting frame is moved by the hydraulic cylinder, thereby moving the side plate.

[0012] To improve the stability of the two side plates, preferably, limit rods are fixedly connected to the left and right sides of the opposite ends of the two side plates. The surfaces of the four limit rods are slidably connected to the left and right sides inside the two support rods, respectively. The limit rods support the two sides of the side plates, thereby improving the stability of the two side plates.

[0013] To reduce the resistance encountered during the conveying of metal bars, preferably, positioning sleeves are movably connected to the surfaces of the multiple positioning rods. During the movement of the metal bars, the multiple positioning sleeves rotate around the multiple positioning rods, thereby reducing the resistance encountered during the conveying of the metal bars.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model, by setting up structural components such as a round bar heating furnace, furnace body, conveying platform, and positioning components, heats the metal bars through the round bar heating furnace, limits the position of the metal bars through the positioning components, and positions the metal bars at the center position of the conveying platform through the synchronization components. The two connecting frames are supported by the first and second sliding rods, and the side plates are moved by the hydraulic cylinder, thus achieving the effect of preventing misalignment during the conveying of the metal bars.

[0021] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 4As shown in the figure, this utility model provides a heating furnace for processing metal rods, including a round bar heating furnace 1 and a positioning assembly 2. The round bar heating furnace 1 includes a furnace body 101 and a conveyor table 102. The conveyor table 102 is installed on the right side of the furnace body 101. The positioning assembly 2 includes two side plates 201, two bottom plates 202, two top plates 203, and multiple positioning rods 204. The opposite ends of the two side plates 201 are movably connected to the front and rear sides of the conveyor table 102, respectively. The opposite sides of the two bottom plates 202 are fixedly connected to the opposite ends of the two side plates 201, respectively. The opposite sides of the two top plates 203 are fixedly connected to the top of the opposite ends of the two side plates 201, respectively. The bottom of the two bottom plates 202 is movably connected to the top of the conveyor table 102. The multiple positioning rods 204... The top of each of the 04 is fixedly connected to the bottom of the two top plates 203, and the bottom of each of the multiple positioning rods 204 is fixedly connected to the top of the two bottom plates 202; the round bar heating furnace 1 is used to heat the metal rods; the positioning component 2 is used to limit the metal rods. In order to prevent the metal rods from being misaligned, the bottom of the opposite ends of the two side plates 201 are movably connected to the support rods 3. The left and right sides of the two support rods 3 are fixedly connected to the left and right sides of the surface of the conveyor table 102, respectively. A synchronization component 4 is provided on the rear side of the front support rod 3. The synchronization component 4 drives the two side plates 201 to move the same distance to the opposite side, so that the front limiting rod 8 and the rear limiting rod 8 move the same distance, thereby placing the metal rod at the center of the top of the conveyor table 102. In order to make the two side plates 201 move the same distance to the opposite side, the positioning component 2 is used to limit the metal rods. The plate 201 moves the same distance. The synchronization assembly 4 includes a support plate 401, a synchronization gear 402, and two connecting frames 403. The front and rear sides of the support plate 401 are fixedly connected to the bottom of the opposite ends of the two support rods 3, respectively. The bottom of the surface of the synchronization gear 402 is movably connected to the interior of the support plate 401. The surface of the left connecting frame 403 is movably connected to the interior of the rear support rod 3, and the surface of the right connecting frame 403 is movably connected to the interior of the front support rod 3. The rear side of the left connecting frame 403 is fixedly connected to the front side of the rear side plate 201, and the front side of the right connecting frame 403 is fixedly connected to the rear side of the front side plate 201. The opposite ends of the two connecting frames 403 are meshed with the surface of the synchronization gear 402. When the front side plate 201 is moved, the front side... Plate 201 drives the right connecting frame 403 to move. During the movement of the right connecting frame 403, the left connecting frame 403 moves backward by the same distance via the synchronous gear 402, thus causing both side plates 201 to move the same distance. To prevent the two connecting frames 403 from tilting and jamming with the synchronous gear 402, two first sliding rods 5 are fixedly connected to the rear side of the front support rod 3. The surfaces of the two first sliding rods 5 are slidably connected to the left and right sides of the interior of the left connecting frame 403, respectively. Two second sliding rods 6 are fixedly connected to the front side of the rear support rod 3. The surfaces of the two second sliding rods 6 are slidably connected to the left and right sides of the interior of the right connecting frame 403, respectively. The first sliding rods 5 and the second sliding rods 6 support the two connecting frames 403.To stabilize the two connecting frames 403 and prevent them from tilting, a hydraulic cylinder 7 is fixedly connected to the rear side of the front support rod 3 to move the front side plate 201. The rear side of the output end of the hydraulic cylinder 7 is fixedly connected to the rear side of the surface of the right connecting frame 403. The hydraulic cylinder 7 moves the right connecting frame 403, thereby moving the side plate 201. To improve the stability of the two side plates 201, limit rods 8 are fixedly connected to the left and right sides of the opposite ends of the two side plates 201. The surfaces of the four limit rods 8 are slidably connected to the left and right sides inside the two support rods 3, respectively. The limit rods 8 support the sides of the side plates 201, thereby improving the stability of the two side plates 201. To reduce the resistance encountered during the conveying of the metal bar, positioning sleeves 9 are movably connected to the surfaces of multiple positioning rods 204. During the movement of the metal bar, the multiple positioning sleeves 9 rotate around the multiple positioning rods 204, thereby reducing the resistance encountered during the conveying of the metal bar.

[0024] The working principle of this utility model:

[0025] When heating the metal rod, the hydraulic cylinder 7 is activated. The output end of the hydraulic cylinder 7 drives the front side plate 201 to move upward through the right connecting frame 403. During the movement of the right connecting frame 403, the left connecting frame 403 is driven to move backward through the synchronous gear 402. During the movement of the left connecting frame 403, the rear side plate 201 is driven to move backward, so that the two side plates 201 move synchronously in opposite directions. During the movement of the two side plates 201, multiple positioning rods 204 are driven to move through the two top plates 203 and the two bottom plates 202, so that the distance between the multiple positioning sleeves 9 is the same as the diameter of the metal rod. The metal rod is placed on the top of the conveyor table 102, and the metal rod is in contact with the multiple positioning sleeves 9. The metal rod is moved into the furnace body 101 through the conveyor table 102. The position of the metal rod is restricted by the multiple positioning sleeves 9 to prevent the metal rod from being misaligned.
