Description

Technical Field

[0001] The utility model relates to the technical field of metal softening annealing furnaces, in particular to a traction roller structure in a metal wire tinning wire annealing furnace. Background Art

[0002] An annealing furnace is a device used to anneal materials. Annealing refers to a heat treatment process in which the material is exposed to high temperature for a long period of time and then slowly cooled. The main purpose is to release stress, increase the ductility and toughness of the material, and produce special microstructures. In the processing of metal wire, annealing treatment in an annealing furnace is required after drawing to reduce the hardness of the metal wire, eliminate residual stress, and reduce the tendency to deformation and cracking.

[0003] When most metal wires are tinned or covered with special coatings, they need to be annealed in an annealing furnace before tinning and other operations are performed. However, after the existing annealing furnace completes the annealing operation on the metal wire, the metal wire is generally pulled out of the annealing furnace by a pulling roller, and the metal wire is naturally cooled to a certain temperature before tinning and other operations are performed. However, the natural cooling of the metal wire results in a long cooling time, which affects the processing efficiency of the metal wire. In addition, the natural cooling cannot accurately control the temperature of the metal wire, which affects the tinning and other operations on the metal wire surface.

[0004] Therefore, it is necessary to propose a traction roller structure in a metal wire tinning wire annealing furnace to solve the above problems. Utility Model Content

Through the mutual cooperation between the internal parts of the traction mechanism and the internal parts of the drive mechanism, the metal wire can be pulled out from the interior of the annealing furnace body while the metal wire is cooled and cooled, thereby improving the cooling speed of the metal wire. It is convenient for the metal wire to be tinned and other operations after it is moved out of the interior of the annealing furnace body, and the spraying efficiency of special coatings on the surface of the metal wire is improved, so as to solve the problem in the prior art that the metal wire is naturally cooled, resulting in a long cooling time, affecting the metal wire processing efficiency, and the natural cooling cannot accurately control the temperature of the metal wire, thereby affecting the tinning and other operations on the metal wire surface.

The inner wall of the traction roller is rotatably connected to a plurality of sealing plates and passes through the interior of the traction roller. The top end of the sealing plate is connected and fixed to a telescopic spring and is located inside the traction roller.

[0008] Preferably, the driving mechanism includes a servo motor, which is installed and fixed at one end of the support frame and is located between the water pipes. The servo motor is rotatably connected to the end of the support frame close to the support frame and passes through the interior of the support frame. The end of the transmission shaft away from the servo motor is connected and fixed to a transmission gear. The end of the traction roller close to the protrusion is connected and fixed to a connecting shaft, and is sleeved with the outer wall of the water pipe.
