Lifting and compressing structure of underfloor furnace door

Abstract

The invention discloses a lifting and compressing structure of an underfloor furnace door. The lifting and compressing structure comprises air cylinders, sliding block devices, support rollers and compressing support frames, wherein each sliding block device is connected with the air cylinder head of the corresponding air cylinder; each support roller is fixedly connected with the corresponding sliding block device; each compressing support frame comprises a compressing seat, a connecting plate, a support framework and a rotating shaft; the compressing seat is mounted near the furnace door; the connecting plate is fixedly connected to the lower part of the compressing seat; the rotating shaft is mounted on the connecting plate; the support framework adopts a V-shaped or right-angle structure; the bending part of the support framework is connected with the rotating shaft; one free end of the support framework is near the furnace door, and the other free end is near the corresponding support roller. The lifting and compressing structure is compact in structure, reliable in motion and flexible in tilting and rotation, and the lifting, compressing and loosening motions for the underfloor furnace door can be well realized; the scheme can be widely applied to single-zone annealing furnaces, the production cost of a single-zone furnace door compressing device is reduced, and greater improvement space in popularization and application of the single-zone furnaces is achieved.

Description

technical field [0001] The invention relates to a locking device for an annealing furnace door, in particular to a lifting and pressing structure for a bottom-mounted furnace door. Background technique [0002] In order to improve the metal properties of the rolled aluminum coil, it is necessary to anneal the rolled aluminum coil. Aluminum coil annealing heat treatment is generally carried out in an annealing furnace. With the vigorous development of the aluminum processing industry, small batch orders are also indispensable for aluminum processing manufacturers. Therefore, single-zone furnaces specially for small batch orders came into being. In order to save the space configuration of the single-zone furnace, the furnace door of the single-zone furnace mostly adopts the bottom-mounted type. However, the simple and effective lifting and pressing problem of the bottom-mounted furnace door has always hindered the promotion of the single-zone furnace. Contents of the invent...
