Description

Technical Field

[0001] This utility model belongs to the technical field of bell-type annealing furnaces, and particularly relates to a flexible quick connector for bell-type annealing furnaces. Background Technology

[0002] A bell-type annealing furnace is a commonly used heat treatment equipment. Its working principle is based on the annealing process of metal materials. The metal workpiece is placed in the furnace, and through three steps of heating, holding and cooling, the metal structure changes, thereby improving its mechanical properties and processing performance.

[0003] The prior art discloses a flexible quick connector for a bell-type annealing furnace, with publication number CN216972630U. This utility model discloses a flexible quick connector for a bell-type annealing furnace, including a corrugated pipe. The upper flange of the corrugated pipe is fixed to the pipe of the heating hood. The corrugated pipe, pipe end, pressure plate, support frame, support plate, spring and upper connector are installed on the heating hood of the bell-type annealing furnace. The lower connector, double-wire pipe and pipe body are installed on the steel structure under the furnace platform of the bell-type annealing furnace. This utility model addresses the problem of excessive offset between the gas connectors of the heating hood and the furnace platform, which prevents effective automatic closure, by designing a combination of corrugated pipe, pipe end, pressure plate, support frame, support plate, spring, and upper connector, as well as increasing the lateral expansion and contraction of the corrugated pipe on the heating hood, increasing the displacement of the supporting heating hood connector frame, and increasing the elevation of some of the quick connectors on the furnace platform. In addition, it solves the problem of gas leakage caused by the height difference between the upper and lower connectors of the quick connector by designing a double-wire pipe. The above is a case that is relatively close to the prior art. The problem with the above technology is that the upper and lower connectors are of equal size, and the upper and lower connectors need to be aligned during the docking process. The corrugated pipe is flexible and is prone to slight shaking, which can cause misalignment between the upper and lower connectors and affect the docking of the upper and lower connectors. Utility Model Content

The surface of the support frame is fixedly connected to the bottom of the inner wall of the connecting pipe, the bottom of the hydraulic cylinder is fixedly connected to the top of the support frame, the interior of the fixed seat is fixedly connected to the top of the surface of the hydraulic cylinder, and the side of the fixed seat near the two adjusting rods is movably connected to the interior of the two adjusting rods. The opposite sides of the two adjusting rods can be in close contact with the inner wall of the bellows. By pressing the inner wall of the bellows with the two adjusting rods, the bellows is positioned.

The protective cylinder 4 blocks the outside of the rotating component 8 to prevent the rotating component 8 from being collided with. This facilitates the positioning of the bellows 102. The adjusting assembly 6 includes a support frame 601, a hydraulic cylinder 602, a fixed seat 603, and two adjusting rods 604. The surface of the support frame 601 is fixedly connected to the bottom of the inner wall of the connecting pipe 101. The bottom of the hydraulic cylinder 602 is fixedly connected to the top of the support frame 601. The interior of the fixed seat 603 is fixedly connected to the top of the surface of the hydraulic cylinder 602. The side of the fixed seat 603 near the two adjusting rods 604 is movably connected to the interior of the two adjusting rods 604. The opposite sides of the two adjusting rods 604 can make close contact with the inner wall of the bellows 102. By pressing the inner wall of the bellows 102 with the two adjusting rods 604, the bellows 102 is positioned. In order to move the two adjusting rods 604, the connecting assembly 7 includes a connecting seat 701, two adjusting rods 604, and two adjusting rods 604.

The edges of the multiple limiting members 203 and the mounting plate 103 are all curved surfaces. The top of the fixing plate 201 is made of rubber. The movement direction of the multiple limiting members 203 is limited by the multiple limiting blocks 10. When the rotating component 8 drives the multiple limiting members 203 to move closer to the mounting plate 103, the multiple limiting members 203 press against the mounting plate 103, causing the mounting plate 103 to fit against the top of the fixing plate 201, thus fixing the mounting plate 103.

[0024] The working principle of this utility model:

[0025] When installing the bellows 102, the bellows 102 is moved downwards and fitted onto the outside of the connecting assembly 7. The mounting plate 103 contacts the fixing plate 201. The hydraulic cylinder 602 is activated, and its output end drives the connecting seat 701 downwards. During the movement of the connecting seat 701, the two adjusting rods 604 are pushed downwards by the two connecting rods 702. The opposite sides of the two adjusting rods 604 are in close contact with the inner wall of the bellows 102, thus positioning the bellows 102. The rotary motor 801 is activated, and its output end drives the connecting plate 803 to rotate through the connecting gear ring 802. During the rotation of the connecting plate 803, the multiple protruding rods 5 drive the multiple limiting members 203 to move closer to the mounting plate 103. The multiple limiting members 203 contact and press the mounting plate 103, thus fixing the mounting plate 103 and connecting the bellows 102 and the connecting pipe 101.
