Description

Soldering machine

The utility model relates to the workpiece electric heating equipment that is used for soldering.

Soldering technology has high-frequency induction heating, heated by electrodes, ferrochrome heating, the direct heating of coal gas etc. to the mode that workpiece adds thermal recovery both at home and abroad at present, general soldering, electric resistance welding equipment all are to utilize the heated by electrodes mode, be that electric current produces high temperature by electrode, pressurize with the processed body of electrode pair again, surface of the work is in dissolve shape and carries out spot welding, butt-joint and soldering, this indirect method is in work under the high temperature because of electrode, it is short to exist electrode life, and energy consumption is big and influence shortcoming such as working environment.High-frequency induction heating then has energy consumption big, shortcomings such as equipment investment expense height.

The purpose of this utility model is the soldering that a kind of equipment that directly heats workpiece to be machined with low-voltage, big electric current of design is finished workpiece, because the temperature of heating is low, carries out the shortcoming that soldering exists so solved aforesaid way.

The purpose of this utility model is achieved through the following technical solutions.Soldering machine is made up of the electrode of a transformer, low-resistance conductor wire and a pair of workpiece pressing, for making voltage reduce to minimum of a value and electric current reaches maximum, the secondary coil of transformer and conductor wire are long-pending conductive plate or the contact rod in single turn low resistance heavy in section that fuses; Electrode and conductive plate (rod) are rigidly connected, and another electrode is connected by flexible braiding electric conductor with conductive plate (rod).

Accompanying drawing is the utility model structural representation.1 is transformer among the figure, and 2 is flexible braid over braid, and 3 is electrode, and 4 is workpiece, and 5 is conductive plate.

Provide embodiment of the present utility model in conjunction with the accompanying drawings.

Present embodiment is the Soldering machine of pressure tapping and bourdon tube, to be Soldering machine should be controlled between the melting temperature to 400 ℃ of tin the heating-up temperature of surface of the work its key, therefore need to select suitable voltage, electric current according to the resistance value of workpiece itself, just can make workpiece be heated to required temperature value, must control the resistance of conducting wire in addition to minimum of a value.Soldering machine is by transformer 1, the conductive plate 5 that secondary coil and conductor wire fuse, and flexible braid over braid 2 and pair of electrodes 3 are formed, and workpiece 4 is for needing the pressure tapping and the bourdon tube of soldering.Transformer 1 is a toroidal transformer, and primary coil is 400 circles, in order to regulate the output voltage of secondary coil, is provided with 5 taps between 300～400 circles, can be for selecting for use arbitrarily.During 380 volts of primary voltages, electric current is 12～20 amperes, secondary coil is single turn conductive plate or contact rod, and its sectional area is 1000～1500 square millimeters, and flexible braid over braid 2 is the copper wire conductive strips, its sectional area is 1000～1500 square millimeters, be connected the middle part of conductive plate 5, fit tightly connection as rigidity, by flexible braid over braid 2 with high-strength bolt, an electrode is moved, in order to the upper and lower material and the clamping of workpiece as all around.Conductive plate 5 also is connected for rigidity fits tightly with electrode 3, and material is all selected T for use ₁～T ₄Number red copper or Cu-ETP material, or the lower material of resistivity, its cupric composition is 99.5～99.95%.With the electrode workpiece pressing, solder stick is sent into the welding position, the primary coil galvanization promptly carries out soldering.Because the temperature of surface of the work is controlled, can obtain good welding quality.

The utility model is equipped with conventional mechanically blanking, location, clamping device, and electrical control gear, meter displaying device promptly become an automatic Soldering machine that automaticity is high.The utility model Soldering machine has the efficient height, crudy is good, improves operator's working condition simultaneously greatly.

The utility model Soldering machine is equally applicable to need workpiece is heated other occasion of finishing soldering, and very big promotion prospect is arranged.
