Description

Technical Field

[0001] The utility model relates to the technical field of tank body manufacturing, and more specifically, to a manufacturing device for a tank body. Background Technique

[0002] During the manufacturing process of the tank body, annealing treatment needs to be carried out on the tank body. Annealing is a metal heat treatment process, which means heating the metal slowly to a certain temperature, maintaining it for a sufficient time, and then cooling it at an appropriate speed. The purpose is to reduce hardness and improve machinability; reduce residual stress, stabilize dimensions, and reduce deformation and crack tendency; refine grains, adjust the structure, and eliminate structural defects. To be precise, annealing is a heat treatment process for materials, including metal materials and non-metal materials. Among them, when manufacturing a tank body with a tank body manufacturing device, a steel coil is required, and during the production process of the steel coil, in order to ensure the quality of the steel coil product, annealing treatment needs to be carried out on the steel coil.

[0003] In the prior art, the annealing equipment for steel coils used in tank body manufacturing often adopts a top heating method, so that heat is transferred from top to bottom to achieve the purpose of annealing inside the annealing equipment for steel coils used in tank body manufacturing. However, in actual use, due to the relatively compact structure of the steel coils used in tank body manufacturing and the poor adaptability of the placement method to the heating unit of the annealing equipment, there are problems of poor annealing uniformity and long time consumption. Secondly, the existing annealing equipment for steel coils used in tank body manufacturing often adopts tracks and a bench truck as the steel coil turnover structure. Since the bench truck often does not provide a steel coil limiting structure, there are phenomena of steel coil shaking and falling, and the safety is insufficient. Finally, the feeding end of the existing annealing equipment for steel coils used in tank body manufacturing often adopts a flip-type drive opening and closing structure, which has a complex opening and closing structure and high maintenance costs, and is not conducive to the quick feeding and discharging of the annealing equipment.

[0004] In view of the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model

[0046] Working principle:

[0047] First, place the steel coil for tank body manufacturing in a standing position in the placement hole 22 of the carrier frame 14. By moving the two threaded columns 23 in the support frame 15 towards each other, the limit blocks 24 on the two threaded columns 23 are urged to extend into the range of the opening of the placement hole 22. Then, rotate the wing nuts 30 on the surface of the threaded columns 23 to fix the limit blocks 24 and limit the steel coil in the placement hole 22. Then, push the turnover rack 3, causing the guide wheels 4 at the bottom of the turnover rack 3 to roll along the guide rail 2, so that the turnover rack 3 drives the carrier frame 14 full of steel coils to transfer from the extension frame 5 to the inside of the furnace body 1. Then, by starting the motor 10 on the drive box 9, the motor 10 is caused to drive the bidirectional screw 16 fixed to its output end to rotate, so that the two threaded sleeves 17 move towards each other along the bidirectional screw 16. Since the right furnace door 7 and the left furnace door 18 distributed around the furnace opening 6 are respectively connected to the two threaded sleeves 17 on the bidirectional screw 16, as the two threaded sleeves 17 move towards each other, the right furnace door 7 and the left furnace door 18 slide towards each other smoothly under the action of the guide grooves 27 and the guide bars 8 until the sealing strip 26 is inserted into the sealing groove 25 to seal the furnace door. When the steel coil placed in a standing position in the carrier frame 14 enters the inside of the furnace body 1, the hot air pipe 12 sends hot air meeting the temperature required for annealing the steel coil into the inside of the furnace body 1, and under the action of the air blowing cover 20, the hot air is blown into the gaps where the steel coil is wound. At this time, start the ceramic heating tube type heating component 11 provided at the inner top of the furnace body 1 to achieve the purpose of synchronous annealing treatment of the inside and outside of the steel coil. When the annealing is completed, start the motor 10 to rotate in the reverse direction in the above manner, so that the right furnace door 7 and the left furnace door 18 move away from each other and then open the furnace opening 6. Then, use the traction equipment to act on the traction ear 19 of the turnover rack 3 to pull the carrier frame 14 away from the furnace body 1, and then unlock the steel coil in the placement hole 22.
