Abstract
The utility model discloses a welding strip annealing furnace which comprises a copper strip guiding-in pipe and a copper strip guiding-out pipe that are symmetrically arranged on the outer wall of a furnace body and are communicated with the interior of the furnace body, wherein the copper strip guiding-out pipe is communicated with a protective gas input pipe, the furnace body is internally provided with a heating facility, and the side and/or the top part of a copper strip are/is communicated with a furnace door. After the welding strip copper strip annealing furnace is adopted for annealing processing, the internal stress of a copper strip can be effectively eliminated, simultaneously, the surface rigidity of the copper strip can be reduced, so that the copper strip can not deform after being subject to surface tinplating process, and a welding strip has good durability. The annealing surface has a simple structure, is easy to operate, and can be designed into different dimensions according to needs.
Description
Technical field
The utility model relates to the processing units of welding, is specifically related to a kind of welding annealing furnace.
Background technology
Welding mainly is the welding material that is used on the photovoltaic module, mainly works to connect conduction.The welding quality is distinguished from many aspects, mainly is that several respects such as weldability, tensile strength, unit elongation, resistivity are come comprehensive examination and evaluation.And the processing units of welding mainly is to be coated with equably to be covered with the tin layer on copper strips, so that the use in when welding.Be with the copper strips after the mechanical process in the prior art, directly carry out the surface and be coated with the tin processing.Because copper strips is in complete processing such as cold rolling, portion can produce internal stress within it, and the surface hardness of copper strips also can be harder, carries out the surface and is coated with tin and handles if this copper strips is directly entered the tin stove, will cause the distortion or the distortion of copper strips.Therefore, in order to eliminate the internal stress of copper strips, and reduce the hardness on surface, be necessary existing welding processing units is improved.
The utility model content
The purpose of this utility model is to overcome the defective in the existing welding processing units, designs a kind of welding annealing furnace of eliminating the copper strips internal stress and reducing surface hardness.
For achieving the above object; the technical solution of the utility model has provided a kind of welding annealing furnace; it is characterized in that; described annealing furnace comprises and is arranged on the furnace body outer wall symmetrically and copper strips ingress pipe that communicates with body of heater inside and copper strips delivery line; on described copper strips delivery line, be communicated with the shielding gas input tube; in described body of heater, be provided with heating facility, be provided with fire door in described side wall of furnace and/or top.
In order to improve the utilization ratio of copper strips annealing furnace, simultaneously also in order to improve the annealing efficiency of copper strips, optimized technical scheme is, described copper strips ingress pipe and copper strips delivery line are provided with some, and described some copper strips ingress pipes and copper strips delivery line all be arranged in parallel.
For prevent to anneal copper strips after coming out of the stove in air by oxidation rapidly, optimized technical scheme also comprises, can with described shielding gas input tube and copper strips delivery line be communicated with the position be arranged on described furnace body outer wall near.
In order to prevent too much air admission copper strips delivery line; simultaneously also for the rare gas element that is input in the copper strips delivery line is squeezed away air; optimized technical scheme also comprises; tilt to be communicated with between described shielding gas input tube and the copper strips delivery line, its vergence direction is towards the outside of described furnace body outer wall.
In order to keep the straight operation of copper strips before and after annealing, optimized technical scheme comprises that also described copper strips ingress pipe and copper strips delivery line are straight tube and perpendicular with described furnace body outer wall.
For the ease of the charge and discharge operations of copper strips, be convenient to the maintenance of annealing furnace etc., optimized technical scheme also comprises, described fire door is arranged on the described furnace body outer wall and described copper strips ingress pipe and the perpendicular side of copper strips delivery line.
Simplify the structure of annealing furnace in order to improve heating efficiency, optimized technical scheme comprises that also described heating facility is for being arranged on intravital nichrome wire of stove or silica tube.
For fear of scattering and disappearing of annealing furnace internal heat, improve energy utilization rate, optimized technical scheme also comprises, is equipped with thermal insulation layer in the sidewall and the top and bottom of described annealing furnace.
Advantage of the present utility model and beneficial effect are: after adopting this welding copper strips annealing furnace that copper strips is carried out anneal, can eliminate the internal stress of copper strips effectively, also can reduce simultaneously the surface hardness of copper strips, it is distorted carrying out can not producing after the surface is coated with process of tin, and can make welding have good toughness.This annealing furnace structure is simple, easy handling, and volume can be according to using needs to be arranged to different sizes.
