Technical Field

[0001] This utility model relates to the technical field of braking between the furnace shell and the coil of a winding annealing furnace. Specifically, this utility model provides a braking device between the furnace shell and the coil of a winding annealing furnace. Background Technology

[0002] Traditional coiling furnace annealing technology suffers from drawbacks such as fixed furnace shell and base, fixed furnace shell outlet, difficult equipment turnover, and long turnover cycle. These drawbacks lead to prolonged dwell time in the coiling furnace, poor heat preservation, and long annealing time. These problems cause difficulties in coiling strip during use, affecting the operational rhythm of factory equipment.

[0003] This invention provides a braking device between the furnace shell and the coil in a coiling annealing furnace. The technical solution of this device aims to optimize the arrangement of the furnace shell outlet direction, so that it changes with the diameter of the coil, facilitating the coiling of the strip inside the furnace. Summary of the Invention

[0004] This invention relates to a braking device between the furnace shell and the winding shaft of a coiling annealing furnace. By extending and retracting a hydraulic cylinder, the distance and positional relationship (separation, overlap, gap) between the lifting seat and the slot are controlled, thus achieving the connection and separation functions of the furnace shell and the winding shaft. The design and implementation of this device enables rapid separation of the winding shaft and the furnace shell; reduces manual operation difficulty and improves production efficiency; furthermore, this device not only ensures a fixed connection between the furnace shell and the winding shaft during overall transportation, but also allows control of the position of the furnace shell opening relative to the winding shaft during rotation at the working position. Through this arrangement, the furnace shell can achieve dynamic balance during production, without bearing additional load, reducing the winding resistance of the strip during coiling on the coiler.

[0005] This utility model provides a braking device between the furnace shell and the coil of a coiling annealing furnace. The braking device includes: a hydraulic cylinder, a connecting rod, a lifting seat, a guide rail, and a slot.

[0006] One end of the hydraulic cylinder has a connector;

[0007] The connecting rod includes an upper connecting rod and a lower connecting rod. One end of the upper connecting rod is hinged to the lower part of the lifting seat, and the other end of the upper connecting rod is hinged to the cylinder connector and one end of the lower connecting rod.

[0008] The other end of the lower connecting rod is hinged to the bottom fixed cylinder support, and one end of the lower connecting rod is hinged to the cylinder connector and the other end of the upper connecting rod.

[0009] The cylinder is hinged to the upper and lower connecting rods at one end, and the cylinder is hinged to the cylinder support at the other end.

[0010] The lifting seat is hinged to one end of the upper connecting rod, allowing it to slide freely up and down with the guide rail.

[0011] Optionally, a brake pad is also provided in the middle of the slot, and the brake pad is fixedly connected to the slot by bolts to form a "mountain" shaped connector.

[0012] Optionally, the "mountain"-shaped connector composed of the brake pad and the slot is frictionally connected to the furnace shell flange on one side and to the shaft flange on the other side; the furnace shell flange and the shaft flange do not directly contact each other.

[0013] Optionally, the lifting and lowering guidance of the card slot and brake pad is achieved through a slide rail; using a pre-formed standard slide rail product can reduce processing and manufacturing costs while improving product reliability.

[0014] Optionally, the brake pads are provided with longitudinal stripes to increase frictional resistance and achieve reliable braking transmission.

[0015] Optionally, the upper connecting rod and the lower connecting rod are made of a single plate with holes to reduce weight, thus reducing the weight of the connecting rod while ensuring its strength.

[0016] Optionally, when the gap between the lifting seat and the slot changes during their use, their purpose also changes.

[0017] When the lifting seat is at its highest point, it is locked against the slot, at which point the friction of the slot is at its maximum. When the cylinder stroke is at its maximum, the lifting seat retracts 1mm downwards, at which point there is a gap between the lifting seat and the slot, achieving frictionless movement between the two.

[0018] Optionally, the pin components include lifting seat pins, cylinder tail pins, cylinder head pins, and connecting rod pins. All of the pin components undergo heat treatment to improve the strength of the parts, as well as their wear resistance and service life.

[0019] Optionally, the lifting seat pin is used to connect the lifting seat and the upper connecting rod; the cylinder tail pin is used to connect the cylinder and the cylinder support; the cylinder head pin is used to connect the cylinder, the upper connecting rod, and the lower connecting rod; and the connecting rod pin is used to connect the lower connecting rod and the connecting rod support.

[0020] The hydraulic cylinder, connecting rod, and guide rail are located on the side of the furnace shell, controlling the output and direction of the driving force. The lifting seat and upper connecting rod are hinged and can move up and down along the guide rail. The slot is on the flange of the furnace shell reel, and the slot and the furnace shell reel are connected by friction. They can be connected or separated under external force. The braking device used in this invention utilizes the principle of friction braking. Power is provided by the hydraulic cylinder and connecting rod mechanism to control the lifting and lowering of the slot, causing frictional contact or separation between the slot and the furnace shell reel, ultimately achieving the connection and separation of the furnace shell and the reel. This invention has a simple structure, reliable operation, and can conveniently achieve braking between the furnace shell and the reel in a coiling annealing furnace.

[0021] This invention relates to a braking device between the furnace shell and the coil in a coiling annealing furnace, enabling both to be connected and separated. The design and implementation of this device not only ensures a fixed connection between the furnace shell and the coil during overall transport but also allows for separation when the furnace shell rotates in the working position. This arrangement allows for relative rotation of the furnace shell and the coil in the working position, thereby automatically adjusting the exit direction of the furnace shell and reducing the winding resistance of the strip during coiling on the coiler.
