Large desktop gas low temperature annealing furnace

Abstract

The invention belongs to the technical field of annealing furnaces, and particularly relates to a large desktop gas low temperature annealing furnace. The large desktop gas low temperature annealing furnace comprises an annealing furnace body, a sealing door, a control box, a smoke discharging pipe, an end cover, a sealing ring, a ring slot, an electric push rod, moving cylinders, moving rings, springs, storing slots, stair rods, fixing rods, bearings, rotating rings and a connecting rod. According to the large desktop gas low temperature annealing furnace, the electric push rod is started, the electric push rod works to drive the end cover to move in reverse, the electric push rod moves in reverse to drive the moving cylinders and the sealing ring to move, the sealing rings move into theinner part of the ring slot, and insects are prevented from entering the inner part of the annealing furnace body; under the action of spring elasticity and the pushing force of the moving cylinders,the moving rings move back to an original position, the stair rods rotate to drive the fixing rods to move in an arc shape, the fixing rods move to drive the rotating rings to move, the rotating ringsmove to drive the connecting rods to move, the connecting rods move to drive the rotating rings on the adjacent stair rods to move, and then the full rotation and unfolding of the stair rods are realized.

Description

technical field [0001] The invention belongs to the technical field of annealing furnaces, in particular to a large-scale desktop gas-fired low-temperature annealing furnace. Background technique [0002] For large welding workpieces, stress relief annealing treatment is required after welding, and then machining. The quality of the heat treatment of the workpiece plays an important role in the machining accuracy and the performance of the workpiece. The uniformity of the furnace temperature is very important in the furnace design. An important link, the uniformity of the furnace temperature directly affects the heat treatment quality of the workpiece. [0003] The currently used annealing furnace has certain defects, such as the lack of a closed protection function for the exhaust pipe, which causes insects in the air to enter the main body of the annealing furnace through the exhaust pipe when the main body of the annealing furnace is not in use, causing damage to the main...

Problems solved by technology

[0006] The object of the present invention is to provide a large-scale desktop gas-fired low-temperature annealing furnace in order to solve the above problems. The present invention adds end caps, sealing rings, ring grooves, electric push rods, moving cylinders, moving rings, springs and storage tanks, Start the electric push rod, the electric push work drives the end cover to move, the end cover moves to drive the moving cylinder to move, the moving cylinder moves to drive the moving ring to move along the storage slot, and then stretches the spring, the spring is stretched to produce elastic force, which is convenient for the annealing furnace To discharge the smoke inside the main body, when it is necessary to close the exhaust pipe, the user starts the electric push rod, the electric push rod works to drive the end cover to move in reverse, and the electric push rod moves in reverse to drive the moving cylinder and the sealing ring to move, and the sealing ring Move into the ring groove to prevent insects from entering the main body of the annealing furnace. The moving ring moves back to its original position under the action of spring force and the push of the moving cylinder. When the main body of the annealing furnace is not in use, insects in the air can easily enter the main body of the annealing furnace through the exhaust pipe, causing damage to the inside of the main body of the annealing furnace and making it inconvenient to use the main body of the annealing furnace. , bearings, rotating rings and connecting rods, the rotation of the stair rod drives the fixed rod to move in an arc shape, the movement of the fixed rod drives the movement of the rotating ring, the movement of the rotating ring drives the movement of the connecting rod, the movement of the connecting rod drives the movement of the rotating ring on the adjacent stair rod, and then Realize the full rotation and unfolding of the stair rods, which solves the problem that the currently used annealing furnace lacks the folding and storage function of the stair rods, causing the stair rods to be fixedly installed on the main body of the annealing furnace, which takes up a lot of space, and the users are easy to bump into the stair rods when they pass by, causing physical damage. disadvantages of harm
