Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of flange production equipment, specifically a flange production heating mechanism. Background Technology
[0002] A flange, also called a flange disc or flange, is a part used to connect shafts. It is used for connecting pipe ends and is also used on equipment inlets and outlets to connect two pieces of equipment, such as a speed reducer flange. When flanges have requirements for strength, hardness, rust prevention, etc., they need to be heat-treated. Heat treatment refers to a metal heat working process in which materials are heated, held at temperature and cooled in a solid state to obtain the desired structure and properties.
[0003] Currently, traditional flange production heating devices typically place the flange on a stacking rack and then into a heating furnace for heating. Placing the flange on the stacking rack cannot ensure uniform and stable heating of the flange, resulting in poor heating uniformity, reduced overall performance, and reduced flange production yield. Therefore, it is necessary to propose a flange production heating mechanism. Utility Model Content
[0004] To address the shortcomings of existing technologies, such as uneven flange heating leading to low flange production yield, this utility model proposes a flange production heating mechanism.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a flange production heating mechanism, including a heating furnace, a bottom plate placed in the inner cavity of the heating furnace, a clamping mechanism movably installed on the top of the bottom plate, a swinging mechanism rotatably installed on the top of the heating furnace, and a heating tube fixedly installed at the bottom of the swinging mechanism;
[0006] The clamping mechanism includes a fixed rod, which is fixedly connected to the top of the base plate. A fixed sleeve is fixedly connected to the outer wall of the fixed rod, and a clamping frame is fixedly connected to the outer wall of the fixed sleeve. The clamping frame is inclined, and a limit rod is slidably connected to one end of the clamping frame. A spring is fixedly connected to one end of the limit rod. The swinging mechanism includes a connecting shaft, which is rotatably connected to the top of the inner cavity of the heating furnace. A swinging rod is fixedly connected to the bottom of the connecting shaft, and mounting rods are fixedly connected to both ends of the swinging rod. The heating tube is fixedly connected to the bottom of the mounting rod. A hydraulic cylinder is fixedly installed on the top of the heating furnace, and the hydraulic cylinder drives the connecting shaft to swing.
[0007] Preferably, the outer wall of the fixed sleeve is fixedly connected to an inclined plate, the inclined surface of the inclined plate is fixedly connected to a stop bar, and the stop bar is fixedly connected to one side of the clamping frame.
[0008] Preferably, one end of the clamping frame has a limiting groove, and the limiting rod is slidably connected in the limiting groove.
[0009] Preferably, the spring is fixedly connected in the limiting groove, and the spring and the limiting rod cooperate to slide and extend, with the limiting rod contacting the inclined surface of the inclined plate.
[0010] Preferably, a guide rod is fixedly connected to one end of the hydraulic cylinder, a guide groove is provided at the top of the guide rod, and a slider is slidably connected to the inner cavity of the guide groove.
[0011] Preferably, a connecting rod is rotatably connected to the top of the slider, and a disk is rotatably connected to one end of the connecting rod.
[0012] Preferably, the top of the connecting shaft extends through the top of the heating furnace, and the center of the disc is fixedly connected to the outer wall of the connecting shaft.
[0013] The advantages of this utility model are:
[0014] 1. This utility model connects a flange with a clamping mechanism, pushing the flange's side hole to engage with a limiting rod. The limiting rod first retracts into the clamping frame's inner cavity, then locks the flange's side hole, ensuring the flange is stably attached to the clamping frame's inner cavity. Simultaneously, the clamping frame tilts, causing the flange to tilt towards the heating tube, allowing the heating tube's heat radiation to more comprehensively irradiate the flange, resulting in more uniform and stable heat radiation. This achieves a more uniform and stable flange heating effect, solving the problem of insufficient flange heating uniformity leading to low flange yield.
[0015] 2. This utility model uses a clamping mechanism to hang flanges on all four sides, while a swing mechanism drives the heating tube to swing intermittently back and forth at 90 degrees. The hydraulic rod drives the swing rod to swing intermittently back and forth. The swinging motion drives the heating on both sides to rotate intermittently by 90 degrees through the mounting rod, so that the flanges on the adjacent sides can receive more stable heat radiation from the heating tube, thereby achieving a more uniform heating effect on the flanges on the adjacent sides. This further solves the problem of insufficient flange heating uniformity leading to low finished product quality of the flange. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0025] This application discloses a flange production heating mechanism. (Refer to...) Figures 1-5 A flange production heating mechanism includes a heating furnace 1, a base plate 2 placed inside the heating furnace 1, a clamping mechanism 3 movably installed on the top of the base plate 2, a swinging mechanism 4 rotatably installed on the top of the heating furnace 1, and a heating pipe 5 fixedly installed at the bottom of the swinging mechanism 4. By hanging the flange on the clamping mechanism 3, with flanges hanging on all four sides of the clamping mechanism 3, and the swinging mechanism 4 intermittently swinging back and forth at 90 degrees, the flanges hanging on all four sides of the clamping mechanism 3 can be subjected to stable heat radiation from the heating pipe 5.
[0026] The clamping mechanism 3 includes a fixed rod 31, which is fixedly connected to the top of the base plate 2. A fixed sleeve 32 is fixedly connected to the outer wall of the fixed rod 31, and a clamping frame 34 is fixedly connected to the outer wall of the fixed sleeve 32. The clamping frame 34 is inclined, and a limit rod 37 is slidably connected to one end of the clamping frame 34. A spring 36 is fixedly connected to one end of the limit rod 37. The swinging mechanism 4 includes a connecting shaft 47, which is rotatably connected to the top of the inner cavity of the heating furnace 1. A swinging rod 48 is fixedly connected to the bottom of the connecting shaft 47, and mounting rods 49 are fixedly connected to both ends of the swinging rod 48. Heating tube 5 is fixedly connected to the bottom of mounting rod 49. Hydraulic cylinder 41 is fixedly installed on the top of heating furnace 1. Hydraulic cylinder 41 drives connecting shaft 47 to swing. The round hole on the side of flange cooperates with limit rod 37 to hang in the inner cavity of clamping frame 34. The clamping frame 34 is tilted so that the flange is tilted to one side of heating tube 5, so that the radiation surface of heating tube 5 can radiate the flange more evenly and effectively. The swing rod 48 is driven by hydraulic cylinder 41 to swing intermittently at 90 degrees, so that the flanges clamped on all four sides of clamping frame 34 can be uniformly and stably radiated by heating tube 5.
[0027] Reference Figure 1 , Figure 3 and Figure 5 An inclined plate 33 is fixedly connected to the outer wall of the fixed sleeve 32. A stop rod 38 is fixedly connected to the inclined surface of the inclined plate 33. The stop rod 38 is fixedly connected to one side of the clamping frame 34. A limit groove 35 is opened at one end of the clamping frame 34. A limit rod 37 is slidably connected in the limit groove 35. A spring 36 is fixedly connected in the limit groove 35. The spring 36 and the limit rod 37 cooperate to slide and extend. The limit rod 37 contacts the inclined surface of the inclined plate 33. The fixed sleeve 32 is stably supported by the fixed rod 31. The clamping frame 34 is located on the inclined surface of the inclined plate 33, so that the clamping frame 34 is tilted. The limit rod 37 at one end of the clamping frame 34 cooperates with the round hole of the flange to clamp and hook it. Push the flange along the inclined surface of the inclined plate 33. The side of the flange pushes the limit rod 37 to retract into the limit groove 35. The spring 36 is compressed. Then the spring 36 pushes the limit rod 37 to cooperate with the round hole of the flange to lock it, so that the flange tilts towards the heating tube 5.
[0028] Reference Figure 2 and Figure 4A guide rod 42 is fixedly connected to one end of a hydraulic cylinder 41. A guide groove 43 is provided at the top of the guide rod 42. A slider 44 is slidably connected to the inner cavity of the guide groove 43. A connecting rod 45 is rotatably connected to the top of the slider 44. A disc 46 is rotatably connected to one end of the connecting rod 45. The top of the connecting shaft 47 passes through the top of the heating furnace 1. The disc 46 is fixedly connected to the outer wall of the connecting shaft 47 at its axial center. The hydraulic cylinder 41 extends outward and pushes the slider 44. The slider 44 slides in the guide groove 43 of the guide rod 42 and drives the connecting rod 45. One end of the connecting rod 45 pushes the disc 46 to rotate 90 degrees. The disc 46 drives the connecting shaft 47 to rotate. The connecting shaft 47 drives the swing rod 48 to rotate. The swing rod 48 drives the mounting rod 49 to rotate, so that the heating tubes 5 on both sides can intermittently rotate 90 degrees back and forth.
[0029] Working principle: During use, the clamping mechanism 3, in conjunction with the flange, clamps and hangs the flange. The flange is pushed in along the inclined surface of the inclined plate 33. The side of the flange pushes the limiting rod 37 to retract into the limiting groove 35 and compress the spring 36. Then, the spring 36 pushes the limiting rod 37 to lock the flange's round hole. The stop rods 38 at both ends of the clamping frame 34 and the limiting rod 37 stably restrict the flange. The fixing rod 31 and multiple fixing sleeves 32 are placed on the top of the base plate 2, with flanges hanging on all four sides. The base plate 2 is placed in the inner cavity of the heating furnace 1, and the heating pipe 5 heats the flange. The oscillating machine... Mechanism 4 causes the heating tube 5 to reciprocate in a 90-degree circular motion. The hydraulic cylinder 41 extends and retracts, pushing the slider 44. The slider 44 slides within the guide groove 43 of the guide rod 42 and drives the connecting rod 45. The connecting rod 45 drives the disc 46 to reciprocate in a 90-degree circular motion, causing the connecting shaft 47 to reciprocate. The swing rod 48 follows the connecting shaft 47 to reciprocate in a 90-degree circular motion and drives the mounting rod 49. The mounting rod 49 drives the heating tubes 5 on both sides to reciprocate in a 90-degree circular motion, so that the flanges on all four sides of the clamping mechanism 3 can receive uniform and stable heat radiation from the heating tubes 5.
