Description

Technical Field

[0001] The present invention relates to the technical field of tempering furnaces, and specifically to a circulating device for a continuous stress-relieving tempering furnace. Background Art

[0002] Tempering furnaces are used for general metal parts to be tempered in air and for heat treatment such as quenching, annealing, and aging of light alloy parts such as aluminum alloy die-castings, pistons, and aluminum plates. The main function of the tempering furnace is to release internal stress. When the casting is heated to 500 to 600 degrees Celsius, the internal stress of the casting is released, making the casting less likely to deform in the future. Tempering and vibration aging are required. The outer shell of the tempering furnace is welded by steel plates and sections, and the trolley is welded by sections and steel plates. The trolley reduces heat radiation and convective losses through soft contact with the furnace lining and a sand seal mechanism, effectively ensuring the sealing performance of the furnace body.

However, it cannot automatically adapt to the tempering treatment of products of different specifications, has poor general performance, and the workpieces are extremely prone to displacement, resulting in serious deformation of the products after collision, so that the heat treatment process cannot be fully guaranteed.

[0010] The present invention provides a circulating device for a continuous stress-relieving tempering furnace. It has the following beneficial effects: (1). The circulation device of this continuous stress-relieving tempering furnace operates through the induction switch inside the central support piece, the internal circuit is connected, the central support piece drives the movement of the torsion bar through the central torsion bar linkage, and then the connecting torsion bar drives the torsion fitting to move. The torsion fitting undergoes a certain amount of torsion, promoting a certain processing foundation inside the equipment and laying a certain installation condition.

[0011] (2). The circulation device of this continuous stress-relieving tempering furnace operates by driving the torsion fitting through the connecting torsion bar. The torsion fitting drives the bottom rod to undergo a certain amount of torsion. The bottom rod drags the center support bar to run accordingly. The center support bar undergoes a counterclockwise rotational swing. There is a rotating torsion bar between the center support bar and the acting shaft. The center support bar drives the rotating torsion bar to move. The rotating torsion bar undergoes a certain amount of deformation and gradually pushes the acting shaft, and forms a certain length margin. Under the cooperative action of the rotating torsion bar, the center support bar drives the acting shaft to run circumferentially.

[0012] (3). When the adaptive device of the circulation device of this continuous stress-relieving tempering furnace rotates, the first disc moves synchronously with the drive of the acting shaft. The first disc gradually slides along the outer surface of the central axis. The guiding and limiting between the first disc and the extending round rod are affected. The guiding and limiting displaces upward under the influence of the centrifugal force of the extending round rod and the first disc. The guiding and limiting extends upward and runs along the track inside the support piece. The base piece plays an auxiliary blocking role. When the first disc rotates, the extending round rod inside the inner cavity is gradually thrown out. The extending round rod drives the pusher to move. The pusher and the extrusion plate strip act on each other by extrusion, so that the workpiece inside the extrusion plate strip has a more stable effect, avoiding excessive displacement, and ensuring a certain auxiliary clamping function inside.

[0013] (4). When the first disc rotates, the side of the first disc gradually squeezes the auxiliary pressure rod. The auxiliary pressure rod retracts inward from the inner cavity of the extrusion plate strip to clamp the workpiece again to ensure the secondary firmness of the workpiece and strengthen the prevention of displacement again.

[0014] (5) The circulating device of the continuous stress-relieving tempering furnace is such that when the first disc rotates along the central axis, it gradually moves downward. The first disc gradually moves into the interior of the surrounding shell. The second disc inside the surrounding shell is adapted to the bayonet of the first disc, and the first disc is just snapped into the interior of the second disc. The cooperation between the second disc and the surrounding shell forms a tendency of collection, so that the device has a certain torsional effect.
