Description

Technical Field

[0001] This utility model relates to the field of furnace tube processing technology, and in particular to a high-efficiency bending processing equipment for industrial furnace tubes. Background Technology

[0002] In the manufacturing process of industrial furnaces, furnace tube bending is a key process, and its precision and efficiency directly affect the rationality of the pipeline layout and the overall performance of the industrial furnace.

[0003] When bending furnace tubes, quenching and cooling are usually required. However, in existing furnace tube processing equipment, the heating furnace and bending mechanism are typically separate. After the furnace tube is heated, it needs to be manually transferred to the bending station. This transfer process can easily cause temperature loss, requiring reheating and increasing energy consumption. During the cooling process, natural cooling or simple water cooling is mostly used. For heat-resistant steel furnace tubes that need to be quenched to improve surface hardness, natural cooling can easily lead to insufficient hardness in the bent section, while direct water cooling may cause cracks due to excessively rapid cooling. This results in a significantly higher scrap rate for furnace tubes, leading to lower production efficiency and quality. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a high-efficiency bending processing equipment for industrial furnace tubes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heating coil is fixedly connected to the inner wall of the bending die, and a connecting wire is connected to one end of the heating coil. A high-frequency power supply box is set on the processing table. One end of the connecting wire passes through the bending die and is electrically connected to the high-frequency power supply box. A heat conduction hole is opened on the outer wall of the bending die near the furnace tube. A clamp is set at the end of the bending die so that the furnace tube can pass through. An atomizing cooling component is set directly above the furnace tube.

[0008] Preferably, the atomizing cooling assembly includes a liquid storage tank located on the processing table, the output end of the liquid storage tank is connected to a connecting pipe, a mounting base is fixedly connected to one side of the processing table, a guide plate is fixedly connected to the bottom of the mounting base, one end of the connecting pipe passes through the mounting base and extends into the interior of the guide plate, a plurality of atomizing nozzles are fixedly connected to the bottom of the guide plate, and a water pump is provided at the end of the connecting pipe near the liquid storage tank.

[0009] Preferably, guide plates are provided on both sides of the guide plate, a recycling box is provided on the support plate, the bottom of the guide plate passes through the processing table and extends into the interior of the recycling box, a water outlet pipe is provided at the bottom of the recycling box, one end of the water outlet pipe passes through the support plate and extends into the interior of the storage tank and communicates with the storage tank, a water pump is provided at one end of the water outlet pipe, and a filter plate is fixedly connected to the inner wall of the recycling box.

[0010] Preferably, two guide rails are symmetrically arranged on the processing table, and a base plate is slidably connected between the two guide rails. A lever handle is connected to the base plate through a protrusion. One end of the lever handle is connected to a connecting block through a connecting shaft. One end of the connecting block is connected to a fixing concave plate through a protrusion. A snap-fit ​​block is fixedly connected inside the fixing concave plate through a connecting rod. An arc-shaped groove for placing a furnace tube is opened on one side of the snap-fit ​​block.

[0011] Preferably, a triangular plate is fixedly connected to one side of the processing table and the guide rail. A circular hole is opened in the middle of the triangular plate, and a threaded rod is provided in the circular hole. One end of the threaded rod is fixedly connected to a rotating handle, and the other end is fixedly connected to a support block. The bottom of the support block is fixedly connected to the base plate.

[0012] Preferably, a drive box is provided on the processing table, a drive motor is provided on one side of the drive box, the output end of the drive motor extends into the interior of the drive box and is fixedly connected to a first gear, a drive rod is provided inside the drive box, and a second gear is fixedly connected to one end of the drive rod, the second gear meshing with the drive gear.

[0016] The beneficial effects of this utility model are:

[0017] This equipment integrates a heating coil into the bending mold, directly heating the area of ​​the furnace tube to be bent in real time via a high-frequency power supply box. This achieves "heating while bending," avoiding heat loss during the transfer process. The heating coil transfers heat directly to the furnace tube through heat conduction holes, and the temperature sensor provides real-time feedback, improving heating efficiency. For traditional natural cooling methods that result in insufficient hardness in the bending section of the heat-resistant steel furnace tube, and the risk of cracking from direct water cooling, this equipment avoids cracking by spraying coolant through atomizing nozzles, reducing the scrap rate. The coolant is collected in a recovery tank via a guide plate and then circulated and filtered by a filter plate and a water pump for reuse, thus reducing coolant consumption and preventing direct discharge of industrial wastewater that pollutes the environment.

[0018] By placing the furnace tube in the arc-shaped groove of the clamp and the snap-fit ​​block to form a double clamping of the inner and outer walls, the clamp fixes the end of the furnace tube, and the snap-fit ​​block pushes the fixing concave plate by turning the handle, so that the furnace tube is tightly embedded in the arc-shaped groove. This avoids the axial movement caused by the traditional single outer wall clamping, and achieves the effect of quick clamping of the furnace tube, reducing auxiliary time and improving the efficiency of furnace tube bending.

[0036] Two guide rails 7 are symmetrically arranged on the processing table 1. A base plate 701 is slidably connected between the two guide rails 7. A lever handle 702 is connected to the base plate 701 through a protrusion. One end of the lever handle 702 is connected to a connecting block 703 through a connecting shaft.

A snap-fit ​​block 706 is fixedly connected inside the fixing concave plate 704 through a connecting rod 705. An arc-shaped groove for placing the furnace tube is opened on one side of the snap-fit ​​block 706.

[0037] A triangular plate 8 is fixedly connected to the processing table 1 and located on one side of the guide rail 7. A circular hole is opened in the middle of the triangular plate 8, and a threaded rod 801 is installed in the circular hole. One end of the threaded rod 801 is fixedly connected to a rotating handle, and the other end is fixedly connected to a support block 802. The bottom of the support block 802 is fixedly connected to the base plate 701.

[0038] A drive box 9 is provided on the processing table 1. A drive motor 901 is provided on one side of the drive box 9. The output end of the drive motor 901 extends into the interior of the drive box 9 and is fixedly connected to a first gear 902. A drive rod 903 is provided inside the drive box 9. A second gear 904 is fixedly connected to one end of the drive rod 903. The second gear 904 meshes with the drive gear 905.

[0039] The drive rod 903 is fixedly connected to the end away from the second gear 904 with a drive gear 905, and the support rod 3 is fitted with a driven gear 906 in the middle, which meshes with the drive gear 905.

[0040] The inner wall of the mounting base 502 is covered with a heat insulation plate 506, and a rectangular hole is opened on the processing table 1 directly below the atomizing nozzle 504.

[0041] A temperature sensor is installed on the inner wall side of the bending mold 4 near the furnace tube, and a pulley 10 is installed at the bottom of the processing table 1.

[0042] In this embodiment, when the furnace tube needs to be bent, the furnace tube first passes through the circular groove placed outside the bending mold 4, and the end of the furnace tube is clamped into the clamp 405. Then, the rotating handle is turned to drive the threaded rod 801 to rotate. When the threaded rod 801 rotates, its thread action drives the support block 802 to move along the guide rail 7. When the support block 802 moves, it drives the base plate 701 and the fixed concave plate 704 to move to the side of the furnace tube. Then, the lever handle 702 is turned so that the lever handle 702 rotates at the connection point between the lever handle 702 and the connecting block 703. When the lever handle 702 rotates, it pushes the fixed concave plate 704 to one side. When the fixed concave plate 704 moves, it drives the clamping block 706 to be clamped to the outside of the furnace tube, so that the furnace tube is clamped into the arc groove inside the clamping block 706, completing the positioning of the furnace tube and preventing displacement during the subsequent bending process of the furnace tube.

[0043] Specifically, after the furnace tube is fixed, the high-frequency power supply box 403 is started. When the high-frequency power supply box 403 starts, the current is transmitted to the heating coil 401 through the connecting wire 402. At this time, the heating coil 401 heats up rapidly, and then the heat is transferred to the surface of the furnace tube through the heat conduction hole 404, thereby heating the section of the furnace tube to be bent. After heating is completed, the drive motor 901 is started immediately. When the drive motor 901 runs, it drives the first gear 902 to rotate. When the first gear 902 rotates, it drives the second gear 904 to mesh and rotate. When the second gear 904 rotates, it drives the drive rod 903 and the drive gear 905 to rotate. When the drive gear 905 rotates, it drives the driven gear 906 to mesh and rotate. When the driven gear 906 rotates, it drives the support rod 3 and the bending mold 4 to rotate. Thus, when the bending mold 4 rotates, it can bend the furnace tube in the circular groove, improving the bending efficiency of the furnace tube. At this time, the temperature sensor provides real-time feedback data. When the temperature reaches a certain set value, the heating is paused.

[0044] Furthermore, after the furnace tube is bent, the water pump 505 is immediately started. When the water pump 505 is running, the coolant inside the storage tank 5 flows through the connecting pipe 501 and the guide plate 503. At this time, the connecting pipe 501 and the guide plate 503 form a flow channel. The coolant then flows in the flow channel and is sprayed out through the atomizing nozzle 504. When the coolant is evenly sprayed from the atomizing nozzle 504 onto the surface of the furnace tube, the processing area of ​​the furnace tube can be cooled. This process continues for 5 to 10 seconds until the surface temperature of the furnace tube drops to a certain level. After the coolant is sprayed out, it flows through the rectangular holes into the recovery tank 601 under the action of the guide plates 6 on both sides. At this time, the suction pump 603 is started. When the suction pump 603 is running, the recovered coolant in the recovery tank 601 is filtered by the filter plate and then flows back to the storage tank 5 through the water outlet pipe 602. This allows the coolant to be recycled, saving resources.
