Description

Technical Field

[0001] The utility model relates to a sliding door device for a double-cavity high-temperature aging furnace, belongs to the technical field of aging furnaces and is used for the double-cavity high-temperature aging furnace on a full-automatic production line of the aging furnace. Background Art

[0002] Existing high temperature aging furnaces mainly use Figure 1 The automatic door opening and closing device shown in the figure includes a box body 1, a door panel 2, a hinge 3, and two cylinders 4. The bottom of the door panel 2 is installed at the opening of the box body 1 through the hinge 3, and the fixed ends of the two cylinders 4 are fixed on the two outer side walls of the box body 1. The output ends of the two cylinders 4 are connected to the two side walls of the door panel 2 through the fulcrum round rod 5, which is used to drive the door panel 2 to rotate upward and close by contracting the output ends of the two cylinders 4, that is, the pistons of the two cylinders 4 are pulled back inward; or, by extending the output ends of the two cylinders 4, that is, the pistons of the two cylinders 4 are pushed outward, to jointly drive the door panel 2 to rotate downward and open.

[0003] When the above scheme is adopted, the pushing and pulling of the piston on the cylinder 4 needs to overcome the gravity of the door panel 2. When the door panel 2 is heavy, the pushing and pulling force of the cylinder 4 is very high. The frequent pulling of the piston rod on the cylinder 4 will cause the door panel on the box body 1 to be damaged by pushing and pulling. On the other hand, the multiple chambers in the high-temperature aging furnace need to be installed in parallel with the number of automatic switching devices equal to the number of chambers, and each cavity needs to be installed with a door panel 2. Each door panel 2 is driven by two cylinders 4 installed on the outer wall of the high-temperature aging furnace. For this reason, many cylinders will be set on the entire high-temperature aging furnace due to the number of chambers, which will increase the production cost. Utility Model Content
