Description

Technical Field

[0002] Square hood furnace is an industrial heat treatment equipment, usually used for heating metal or other materials. There is a cover on the top that can be opened or closed. This cover is like a cover, hence the name "square hood furnace". The square hood furnace consists of a heating hood, a furnace base, and a lifting mechanism. When the workpiece enters and exits the furnace, the heating hood is required to be lifted to a certain height to facilitate the entry and exit of the workpiece.

A furnace body 2 is arranged on the top of the bottom plate 1, a hood body 3 is movably installed on the top of the furnace body 2, a fixing frame 4 is fixedly installed on the top of the bottom plate 1, a lifting component 5 is fixedly installed on the top of the inner cavity of the fixing frame 4, a supporting frame 6 is fixedly installed on the inner cavity of the lifting component 5, the front and rear sides of the supporting frame 6 are fixedly installed with fixing components 7, and the front and rear sides of both sides of the bottom plate 1 are fixedly installed with mounting plates 8. The lifting assembly 5 includes a bidirectional motor 501, which is fixedly mounted on the top of the inner cavity of the fixed frame 4.

[0038] During the implementation process, the cover body 3 is fixed by the fixing component 7, and then the bidirectional motor 501 is started. When in use, the bidirectional motor 501 will drive the two rotating rods 502 to rotate, and the two first bevel gears 503 will rotate along with the two rotating rods 502, and the second bevel gear 504 will rotate along with the first bevel gear 503, and the screw rod 505 will rotate along with the second bevel gear 504, and the two fixing blocks 506 will move along with the screw rod 505, and the connecting block 507 will move along with the movement of the fixing block 506, and the support frame 6 and the fixing component 7 will move along with the movement of the connecting block 507, thereby driving the cover body 3 to move toward the top.

[0041] During the implementation process, the two arc clamps 704 are moved to the front and rear sides of the cover body 3, and the rotating disk 703 is rotated. The rotating disk 703 will drive the threaded rod 702 to rotate when it rotates. The threaded rod 702 is threadedly connected to the inside of the threaded sleeve 701.

The cover body 3 can be clamped and fixed by the coordinated use of the two arc clamps 704, so that the cover body 3 is more stable when it is raised and lowered, and there will be no shaking.

[0042] During installation, the two arc clamps 704 are moved to the front and rear sides of the cover body 3, and the rotating disk 703 is rotated. When the rotating disk 703 rotates, the threaded rod 702 is driven to rotate. The threaded rod 702 is threadedly connected to the inside of the threaded sleeve 701. When the threaded rod 702 rotates, it will move toward the inside of the support frame 6. The arc clamp 704 is installed on the threaded rod 702 and will move with the movement of the threaded rod 702. The coordinated use of the two arc clamps 704 can clamp and fix the cover body 3, making the cover body 3 more stable when lifting and lowering, and will not shake. Then, by starting the bidirectional motor 501, the bidirectional motor 501 will drive the two rotating rods 502 to rotate when in use, and the two first bevel gears 503 will rotate with the two rotating rods 502.

When the lifting speeds on both sides of the cover body 3 are synchronized, it can ensure that the cover body 3 remains balanced during the ascent or descent process, which can reduce the imbalance caused by the lifting speed of one side being too fast or too slow, thereby improving the stability and safety of the equipment.
