Description

Technical Field

[0001] The invention belongs to the technical field of mesh-belt isothermal normalizing furnaces, and in particular relates to an auxiliary unloading device for shaft parts of a mesh-belt isothermal normalizing furnace. Background Art

[0002] The working principle of the isothermal normalizing furnace is mainly based on precise temperature and time control. During the heating stage, the workpiece is placed in the furnace and heated by electric heating elements or gas combustion. Unlike the traditional normalizing process, after the workpiece is quickly heated to the austenitizing temperature, it will be immediately transferred to a pre-set insulation chamber and stay at this temperature for a long time. In this way, the internal structure of the workpiece will undergo isothermal transformation, such as the formation of pearlite, bainite or other preset organizational forms. The main feature is temperature uniformity: the isothermal normalizing furnace can create a relatively uniform and precisely controlled temperature field in the entire furnace, ensuring that the workpiece completes the organizational transformation in a short time. Precise control: The use of advanced temperature control technology and intelligent control system can accurately set and control the temperature changes during heating, insulation and cooling. Gas protection: Some equipment is also equipped with a gas protection device to prevent the workpiece from oxidizing at high temperature, ensuring high-quality surface and ideal metallurgical bonding properties. The mesh belt isothermal normalizing furnace can be used to process shaft parts, and the unloading device needs to be used for auxiliary operation when loading and unloading. At present, the auxiliary unloading device mainly has the following consensus defects:

[0003] During the use of the traditional mesh-belt isothermal normalizing furnace, shaft parts need to be individually clamped for loading and unloading during the unloading process. It is impossible to screen a large number of shaft parts into single shaft parts and then send them to the normalizing furnace in an orderly manner without interruption, which makes the overall auxiliary unloading device inconvenient to operate. Summary of the invention

[0004] The object of the present invention is to provide a mesh-belt isothermal normalizing furnace shaft-type auxiliary unloading device, aiming to solve the problem in the prior art that a large number of shaft-type parts cannot be screened into single shaft-type parts without interruption and then sent to the inside of the normalizing furnace in an orderly manner, thereby making the overall auxiliary unloading device inconvenient to operate.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A mesh-belt isothermal normalizing furnace shaft-type auxiliary unloading device comprises two base frames, the top ends of the two base frames are rotatably connected with driven rods, the outer sides of the driven rods are fixedly mounted with hexagonal shafts, the outer sides of the hexagonal shafts are sleeved with a plurality of conveying plates, both ends of the plurality of conveying plates are fixedly mounted with rotating rings, the inner side walls of the rotating rings are rotatably connected with rotating shafts, the inner side walls of the conveying plates are rotatably connected with steering rods, the outer sides of the steering rods are fixedly mounted with bottom rods, the top ends of the bottom rods are rotatably connected with middle rods, and the top ends of the middle rods are rotatably connected with top rods.

[0010] As a preferred embodiment of the present invention, one end of the inner wall of the steering rod is slidably connected to an operating rod, and the inner side wall of the operating rod is slidably connected to one end of the winding rod.

[0011] As a preferred embodiment of the present invention, a driving motor is fixedly mounted on the outer side of one of the base frames, a driving rod is fixedly mounted on the output end of the driving motor, and the outer side of the driving rod is rotatably connected to the inner side wall of the base frame.

[0012] As a preferred embodiment of the present invention, one end of one of the driven rod and the driving rod is fixedly mounted with a pulley, and a transmission belt is sleeved on the outer side of the pulley.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1) The hexagonal shaft is driven to rotate by the set driven rod, so that the conveying plate can be transmitted on its outside through the action of the rotating ring and the rotating shaft. Since the shaft parts have different sizes during the loading process, the bottom rod, middle rod and top rod on the conveying plate can be rotated out according to the required loading rate of the shaft parts, so as to place and transport the shaft parts and continue to keep them inside the conveying plate, so that it is more convenient to increase or decrease the number of bottom rods to be unfolded according to the required situation, thereby improving the convenience of operation of the overall unloading device.

[0015] 2) The winding rod is arranged to drive the winding column to rotate inside the steering rod, so that the bottom rod, the middle rod and the top rod can rotate relative to each other, and the springs between the bottom rod and the middle rod, and between the middle rod and the top rod can form an arc state, which is more convenient for screening and conveying shaft parts. The stability of the shaft parts on it prevents the shaft parts from rolling, and the arc of the formation can be adjusted, thereby improving the application range of the overall device for loading and unloading shaft parts.

[0025] During specific use, when the auxiliary unloading device is used to act on shaft parts, the hexagonal shaft 3 can be driven to rotate through the driven rod 2, so that multiple conveying plates 4 can be transmitted on the outside of the hexagonal shaft 3 through the action of the rotating ring 41 and the rotating shaft 42, and the bottom rod 6 on the conveying plate 4 can be rotated out from the inside of the conveying plate 4 through the rotation of the steering rod 5, and is used for screening and loading and unloading shaft parts, and can also continue to be kept inside the conveying plate 4 without affecting the screening of shaft parts, and the rotation between the bottom rod 6, the middle rod 7 and the top rod 8 can be based on the curvature of the shaft parts. The curvature of the curvature of the post-composition bending degree is changed, so that it is more suitable for screening operations on shaft parts of different coarseness and fineness, thereby improving the efficiency of the overall unloading device in conveying shaft parts, and improving the scope of application of the overall device.

[0026] Preferably, the inner side wall of the steering rod 5 is rotatably connected to a winding rod 9, a plurality of winding posts 91 are fixedly installed on the outer side of the winding rod 9, a pulling belt 92 is fixedly installed on the outer side of the plurality of winding posts 91, the outer sides of the pulling belt 92 are respectively slidably connected to the inner side walls of the bottom rod 6 and the middle rod 7, and the end of the pulling belt 92 is fixedly connected to the outer side of the top rod 8.

[0033] During specific use, when the winding rod 9 needs to be rotated, the operating rod 11 can be pulled out from the inside of the steering rod 5 and detached from the steering rod 5. Since the sliding part between the operating rod 11 and the winding rod 9 is square, the winding rod 9 can be driven to rotate by rotating the operating rod 11. After rotating to a suitable angle, the operating rod 11 can be inserted into the inside of the steering rod 5, thereby fixing the winding rod 9 by fixing the operating rod 11 and the steering rod 5.
