Technical Field
[0001] The utility model belongs to the technical field of fire door processing, and particularly relates to a plate bending mechanism for a metal fire door. Background Technique
[0002] A fire door refers to a door that can meet the requirements of fire resistance stability, integrity, and heat insulation within a certain period of time. Fire doors are generally installed at fire compartment boundaries, evacuation stairwells, vertical shafts, and other locations where there are fire partitions with a certain fire resistance.
[0003] In the process of implementing the present utility model, the inventor found that there are at least the following problems in this technology: Fire doors are usually made of metal. When processing the plates of such metal fire doors, bending work is involved. Currently, the mechanisms for bending such plates can usually only bend one end of the plate at a time. If the other end of the plate needs to be bent, the plate needs to be repositioned, which reduces efficiency. Moreover, the position of the bending mechanism is not adjustable, resulting in the inability to adapt to the bending of plates with different lengths.
[0004] Therefore, we propose a plate bending mechanism for a metal fire door to solve the above problems. Content of the Utility Model
[0005] The main purpose of the present utility model is to provide a plate bending mechanism for a metal fire door, which uses two pressing platforms to simultaneously bend both sides of the plates related to the fire door, achieving more efficient bending work. Moreover, since the distance between the two support seats is adjustable, it can adapt to the bending work of plates related to fire doors with different lengths, and can effectively solve the problems in the background technique.
[0006] To achieve the above purpose, the present utility model adopts the following technical solution:
[0007] A plate bending mechanism for a metal fire door includes a workbench and a plate bending assembly located on the workbench. A motor is horizontally installed on one side wall of the workbench, and an activity groove is also formed on the workbench. The activity groove has two openings, and the two openings of the activity groove are symmetric on both sides of the workbench. The output shaft of the motor is coaxially connected to a screw rod, and inner sliding seats are respectively thread sleeved at both ends of the screw rod. Both inner sliding seats are in contact with the bottom wall of the activity groove, and the thread directions at both ends of the screw rod are opposite.
[0008] The plate bending assembly includes support seats symmetrically welded on the two inner sliding seats, hydraulic cylinders respectively installed on the top walls of the two support seats, pressing platforms respectively connected below the two hydraulic cylinders, and receiving seats respectively welded on the inner sides of the two support seats. The receiving seats are designed in a U shape.
[0009] As a preferred implementation scheme, the screw is horizontally arranged in the movable groove, and both ends of the screw are rotatably connected to the workbench; so that the screw can run stably under the drive of the motor, and the motor needs to be powered by external power facilities.
[0010] As a preferred implementation scheme, sliding rods are symmetrically welded on both sides of the top wall of the press platform, and both sliding rods slide through the support seat; so that when the press platform is raised or lowered, the two sliding rods can be driven to rise or fall on the support seat, thereby utilizing the two sliding rods to make the lifting of the press platform more stable.
[0011] As a preferred embodiment, the receiving seat in the support seat is located directly below the pressing platform, and the receiving seat is adapted to the pressing platform, so that the pressing platform can be pressed just into the receiving seat, thereby punching the fire door panel into the receiving seat and bending it 90°.
[0012] As a preferred embodiment, a protrusion is welded at the center of the top wall of the workbench, and an inverted U-shaped receiving frame is welded on the protrusion, wherein an electric telescopic rod is installed on the receiving frame, and a positioning platform is connected below the electric telescopic rod; the positioning platform can be driven to rise and fall by the operation of the electric telescopic rod.
[0013] As a preferred embodiment, the electric telescopic rod is vertically arranged, the top end of the electric telescopic rod is fixed on the receiving frame, and the positioning platform is horizontally arranged just above the protruding portion; so that the positioning platform can fix the fire door panel before it is bent.
[0014] In summary, the technical effects and advantages of the utility model are as follows:
[0015] The metal fire door plate bending mechanism, the motor drives the screw to operate, which can make the two support seats move toward each other to adjust the distance between the two support seats, and then drive the two hydraulic cylinders to operate, and use two presses to bend both sides of the fire door related plates at the same time, thereby achieving more efficient bending work. Moreover, since the distance between the two support seats is adjustable, it is suitable for the bending work of fire door related plates of different lengths. BRIEF DESCRIPTION OF THE DRAWINGS
