Description
Technical Field
The application relates to a preset brazing filler metal connecting piece, which is mainly suitable for brazing between connecting pieces.
Background
The fixation between the two connectors is usually done in two ways. The first method is as follows: adopting screw thread or screw to fix and connect; the second method comprises the following steps: the opposite surfaces of the two copper materials are brazed.
Adopt two kinds of current modes to braze, mode one mainly influences the whole automatic process of customer, and work efficiency is lower, influences the production rhythm. And the brazing filler metal is preset on the copper material in a pressing or riveting or sleeving mode, and at the moment, the preset brazing filler metal is easy to fall off due to the influence of external force in the transportation process, so that false welding occurs after brazing, the quality reliability of products is reduced, and the other possibility is that the process is complicated, the efficiency is low, and the automation is influenced. For example, in the refrigeration industry, the connection of the headers and the elbows in the evaporator and condenser are typically brazed. A welding ring is required to be preset on a bent head before brazing, the welding ring is preset on the bent head or is placed in a special tool through the welding ring, then the bent head is aligned, a rubber hammer is used for knocking the bent head, the welding ring is sleeved on the bent head or is automatically sleeved into the bent head through customized equipment, the bent head sleeved with the welding ring is assembled on a water collecting pipe subjected to flaring, and the whole body enters a furnace for flame brazing. For example, the connection of the four-way valve end cover in the refrigeration industry is generally performed by adopting a high-frequency brazing mode. When the existing lantern ring mode is adopted for brazing, manual operation is needed, the production efficiency is low, the method is not suitable for large-scale production, the integral automation process of brazing is influenced, and the production cost is high; on the other hand, the welding ring needs to be subjected to processes such as extrusion, wire drawing, ring manufacturing, cleaning and the like, when the specification of the welding ring changes, the processes of different processes need to change, the manufacturing period is long, the yield and the efficiency are affected, and the welding ring is easy to fall off or shift after being sleeved and affects the welding quality.
Disclosure of Invention
The technical problem that this application was solved is overcome the above-mentioned not enough that exists among the prior art, and provides a structure succinct, convenient to use, and is with low costs, effectual connecting piece of presetting brazing filler metal for brazing filler metal manufacturing enterprise and connecting piece manufacturing enterprise cross the trade reorganization and optimize production technology, make brazing filler metal manufacturing enterprise omit originally must go on brazing filler metal shaping process and directly melt and cover or coat on the connecting piece of application object.
The technical scheme adopted by the application for solving the technical problems is as follows: a connecting piece with preset brazing filler metal is matched with another connected piece, and the connecting piece is characterized in that: the relative position of the connecting piece and the connected piece adopts the cladding or coating of the brazing filler metal in the prior art, so that a brazing filler metal production enterprise can save processes, installers save the step of positioning and placing the brazing filler metal, the brazing filler metal is fixed and reliable, and the brazing effect is improved.
According to the method, laser cladding is adopted, the thickness of the brazing filler metal after laser cladding is 0.05-3.0 mm, and the brazing filler metal after cladding is smooth in surface and uniform in thickness distribution.
This application the connecting piece, by connecting piece hookup location's material looks adaptation, the connecting piece, by the hookup location of connecting piece all adopt the copper product, especially same kind of copper product, for example the connecting piece, by the hookup location of connecting piece be red copper or connecting piece, by the hookup location of connecting piece be the brass, the welding effect is better.
Compared with the prior art, the application has the following advantages and effects: the structure is simple, the use is convenient, the cost is low, and the effect is good.

Detailed Description
The present application will be described in further detail below with reference to the accompanying drawings by way of examples, which are illustrative of the present application and are not limited to the following examples.
Referring to fig. 1, a connecting piece 1 of embodiment 1 of the present application is a brass base with a brazing filler metal 2 disposed on a surface thereof, and the embodiment is particularly suitable for braze welding connection between a relay, a transformer and the brass base in the ammeter industry, and in the embodiment, the brazing filler metal 2 is prefabricated on the brass base in a laser cladding manner, so that the brazing filler metal 2 is locally and preferentially connected with a brass connecting surface to form good braze welding connection, thereby achieving the purpose of pre-disposing the brazing filler metal 2 on the brass base; the embodiment avoids the problems of workload increase, cost increase or false welding and the like which are possibly caused by the situation that the conventional preset soldering lug is easy to separate or shift and the like; the automation of brazing is conveniently realized, the overall quality and reliability of the product after welding are improved, and the reject ratio of the product is reduced.
The thickness of the brazing filler metal 2 after laser cladding is 0.05-3.0 mm, and the surface of the brazing filler metal 2 after cladding is smooth and is uniform in thickness distribution.
Referring to fig. 2, the connector 1 of the embodiment 2 is a red copper elbow with brazing filler metal 2 on the surface, and is particularly suitable for connecting a water collecting pipe and a red copper elbow in an evaporator and a condenser in the refrigeration industry, the brazing filler metal 2 is prefabricated on the red copper pipe by adopting a laser heating and wire feeding mode, then the red copper pipe with the prefabricated brazing filler metal 2 is made into the red copper elbow, the brazing can be directly realized, and the automation of the brazing process is realized. The embodiment avoids the complexity of the conventional method, improves the efficiency and saves the cost.
