Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a synchronization mechanism for the movement of a furnace door. Background Art

[0002] Vertical vacuum furnaces or sintering furnaces mostly adopt a downward-opening furnace door structure. The movement mechanisms and solutions of the furnace door generally adopt the following two solutions:

[0003] Solution 1: The movement of the furnace door is driven by a synchronous motor to rotate multiple lead screws to generate axial displacement, lifting or lowering the furnace door. The guidance of the furnace door relies on the rigid support of the lead screws at the fixed fulcrum of the furnace door. When the furnace door is lifted or lowered, due to the uneven weights of each fulcrum and the uneven friction forces on the guiding parts, individual parts are prone to jamming and poor movement, and there is a risk of tilting.

[0004] Solution 2: Hydraulic lifting cylinders or push-pull cylinders are used to support the up-and-down reciprocating movement of the furnace door. The advantage of the hydraulic cylinders is that the movement is relatively smooth during the lifting process. The disadvantage is that due to factors such as the length and flow rate of the hydraulic pipelines, it is very difficult to synchronize the lifting movements of each hydraulic cylinder. As a result, due to the uneven load weights of the furnace door and the factor of asynchronous movement, there is a risk of tilting of the furnace door during movement.

[0005] In view of the above defects, the designer actively conducts research and innovation in order to create a synchronization mechanism for the movement of a furnace door, making it more valuable in industrial applications. Summary of the Utility Model

[0006] To solve any of the above technical problems, the purpose of the utility model is to provide a synchronization mechanism for the movement of a furnace door.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A synchronization mechanism for the movement of a furnace door includes a frame, a furnace body, and a furnace door. A top beam is installed at the top of the frame. The periphery of the furnace body is installed on the top beam through furnace body mounting seats, and a furnace door is installed at the bottom of the furnace body.

[0009] On the top beam outside the furnace body, a plurality of lifting modules are installed through lifting module supports. At the bottom of the furnace door directly below the lifting modules, a furnace door support is installed. The furnace door support is connected to the frame through a furnace door synchronization component.

[0010] The furnace door synchronization assembly includes a lifting support, a synchronization shaft, synchronization gears, and a synchronization rack. The driving end at the bottom of the lifting module is connected to the inner side of the lifting support directly below. Two mutually perpendicular support blocks are provided on the outer side of the lifting support. Synchronization gear supports are installed on the support blocks. Synchronization racks distributed vertically are installed on both sides of the frame outside the support blocks. A synchronization shaft is installed on the synchronization gear support. The synchronization gears installed on the synchronization shaft mesh with the synchronization racks.

[0011] As a further improvement of the present utility model, linear guide rails distributed vertically are installed on both sides of the frame inside the support blocks. The linear sliders installed inside the support blocks are connected to the linear guide rails.

[0012] As a further improvement of the present utility model, the number of lifting modules is four and they are evenly distributed at the four diagonals of the top beam. The number of furnace door synchronization assemblies is four, and the synchronization gear supports of two adjacent furnace door synchronization assemblies are installed on both sides of the same synchronization shaft.

[0013] As a further improvement of the present utility model, the lifting module is a hydraulic cylinder or a pneumatic cylinder or an electric push rod.

[0014] As a further improvement of the present utility model, the synchronization gear and the synchronization shaft are locked and fixed by a key.

[0015] As a further improvement of the present utility model, the synchronization shaft and the synchronization gear support are connected by bearings.

[0016] By means of the above solution, the present utility model has at least the following advantages:

[0017] The present utility model relies on the meshing action of the synchronization gears and the synchronization racks, greatly improving the lifting synchronization of the furnace door and the closing reliability of the furnace door.

[0018] The structure of the present utility model is simple and convenient to install. After installation, it solves the flow error caused by inconsistent lengths of hydraulic pipelines and the low control precision requirements for multi-cylinder pressure, thereby greatly reducing the control precision of the equipment, making the operation more convenient and the cost lower.

[0027] Embodiment

[0028] As Figures 1 to 2 shown,

[0029] A synchronization mechanism for the movement of a furnace door, comprising a frame 1, a furnace body 3 and a furnace door 7. A top beam 2 is installed at the top of the frame 1. The periphery of the furnace body 3 is installed on the top beam 2 through furnace body mounting seats 6. The furnace door 7 is installed at the bottom of the furnace body 3.

[0030] On the top beam 2 outside the furnace body 3, a number of lifting modules 5 are installed through lifting module supports 4. At the bottom of the furnace door 7 directly below the lifting module 5, a furnace door support 8 is installed. The furnace door support 8 is connected to the frame 1 through a furnace door synchronization assembly 9. The lifting module 5 is a hydraulic cylinder or a pneumatic cylinder or an electric push rod.

[0031] 1. The furnace door synchronization assembly 9 includes a lifting support 10, a synchronization shaft 12, a synchronization gear 15 and a synchronization rack 16. The driving end at the bottom of the lifting module 5 is connected to the inner side of the directly below lifting support 10. On the outer side of the lifting support 10, two mutually perpendicular support blocks are provided. On the support blocks, a synchronization gear support 11 is installed. On both sides of the frame 1 outside the support blocks, synchronization racks 16 distributed along the vertical direction are installed. On the synchronization gear support 11, a synchronization shaft 12 is installed. The synchronization shaft 12 and the synchronization gear support 11 are connected through bearings. The synchronization gear 15 installed on the synchronization shaft 12 meshes with the synchronization rack 16. The synchronization gear 15 and the synchronization shaft 12 are locked and fixed through keys.

[0032] 2. On both sides of the frame 1 inside the support blocks, linear guide rails 13 distributed along the vertical direction are installed. The linear sliders 14 installed inside the support blocks are connected to the linear guide rails 13.

[0033] Among them, the number of lifting modules 5 is four and they are evenly distributed at the four diagonals of the top beam 2. The number of furnace door synchronization assemblies 9 is four, and the synchronization gear supports 11 of two adjacent furnace door synchronization assemblies 9 are installed on both sides of the same synchronization shaft 12.

[0034] The utility model adopts the installation of lifting modules 5, linear slider modules and synchronization gear and rack modules on the top beam 2 of the frame 1. The furnace door is supported by a plurality of symmetric lifting supports 10. On the lifting support 10, a synchronization gear support 11, a synchronization shaft 12 and a synchronization gear 15 are installed. The synchronization gear 15 and the synchronization shaft 12 are locked and fixed through keys. The synchronization shaft 12 and the synchronization gear support 11 are connected through bearings to ensure the rotation of the synchronization shaft 12 and the synchronization gear support 11. The synchronization gear 15 meshes with the synchronization rack 16 for movement, such as Figure 2 . The lifting modules 5 arranged above the top beam 2 are linked with a plurality of lifting supports 10 of the furnace door. The support blocks and the frame 1 use the linear guide rails 13 and the linear sliders 14 as guides. At the same time, two adjacent supports are connected by synchronization gears and synchronization shafts. The synchronization gears mesh with the racks of the furnace door support for movement.

[0035] Through the rigid connection between the synchronous gear and the lifting base and the meshing movement between the synchronous gear and the synchronous rack, the present utility model ensures the consistency of the up-and-down movement of the lifting base, compensates for the tiny displacement and the difference in lifting force caused by the asynchrony of the hydraulic cylinders, and thus avoids the unbalanced movement of the furnace door, which may otherwise lead to the malfunction of the movement and functions of the furnace door.

These terms are only used for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the technical features indicated. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features.
