Description
Technical field
The utility model relates to technical field of welding equipment, more particularly, relates to a kind of copper-aluminium joint resistance welder.
Background technology
China is the country of copper resource relative shortage, bauxite resource relative abundance, and for air conditioner industry, its refrigeration piping many uses copper material, in order to reduce costs, portions use aluminum pipe be feasible, but because copper pipe differs about 400 DEG C with aluminum pipe fusing point, therefore, often need the pipeline adopting copper-aluminium joint to realize between different tubing to connect in copper pipe and the junction of aluminum pipe.In the connection device of existing copper-aluminium joint, the upset butt welder that uses is connected with aluminum pipe copper pipe more, and then the inner chamber enlarging process of butt joint.The upset butt welder of existing use mainly contains manual eccentric block type and hand power screw formula butt welding machine, the welding quality extremely unstable of these two kinds of butt welding machines, when being energized welding, the easy starting the arc of jaw, electric resistance welding heat is unstable, makes welding quality uniformity poor, thus makes joint quality uneven.
Utility model content
The purpose of this utility model is to provide the copper-aluminium joint resistance welder that a kind of structure is simple, technological parameter is stable, to overcome the deficiencies in the prior art.
The purpose of this utility model is achieved in that a kind of copper-aluminium joint resistance welder, for the connection of copper pipe and aluminum pipe, comprise frame, traveling electrode seat, fixed electrode seat, the tip side undergauge of described copper pipe, also comprise aluminum pipe clamping, copper pipe clamping, in the below of described traveling electrode seat, the top of described fixed electrode seat is respectively arranged with the aluminum pipe clamping for being clamped by aluminum pipe, the clamping of copper pipe clamping next-door neighbour aluminum pipe arranges and is driven by propulsion cylinder, frame is also provided with blow cylinder, one end of described blow cylinder connects impact bar, described impact bar is driven by blow cylinder and can be inserted in copper pipe thus extrude expanding by the tip side of copper pipe.
The diameter of described impact bar is less than copper pipe internal diameter and slightly larger than aluminum pipe internal diameter.
The end of described impact bar is spherical top guide, and the diameter of described top guide is less than the minimum diameter of copper pipe joint end.
Described traveling electrode seat is fixed on below aluminum pipe top mold frame, arranges aluminum pipe clamping cylinder above described aluminum pipe top mold frame.
Described copper pipe clamping comprises upper clamp formwork, lower clamp formwork, and the top of described upper clamp formwork is provided with copper pipe clamping cylinder.
The beneficial effects of the utility model are: the utility model adopts the mode of cylinder clamping to replace existing manual eccentric block type and hand power screw formula, because the pressure of pneumatic shuttle is highly stable, the firm performance of the clamping of workpiece to be processed is effectively ensured, thus improves welding quality.
Machine operation of the present utility model is simply laborsaving, and labor strength is little.
Accompanying drawing explanation
Fig. 1 is the utility model copper-aluminium joint resistance welder structural representation.
Fig. 2 is the structural representation of the copper-aluminium joint that the utility model processing obtains.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
See Fig. 1, the utility model provides a kind of copper-aluminium joint resistance welder, for the connection of copper pipe and aluminum pipe, comprise frame (not shown), traveling electrode seat 6, fixed electrode seat 7, traveling electrode seat 6 is positioned at the top of fixed electrode seat 7 and can moves in the vertical direction, and traveling electrode seat 6, fixed electrode seat 7 is fixed with respectively the electrode assembly for electric resistance welding.Aluminum pipe clamping 8 is respectively arranged with above the below of described traveling electrode seat, described fixed electrode seat, aluminum pipe clamping 8 is upper and lower a pair totally, the opposite face of clamping is symmetrical arranged respectively the half slot for holding aluminum pipe, aluminum pipe clamping below traveling electrode seat descending and with aluminum pipe clamping matched moulds on fixed electrode seat time, aluminum pipe is by mold cramping.As shown in the figure, copper pipe clamping 9 is close to setting on the right side of aluminum pipe clamping 8 and is driven by propulsion cylinder 3, frame is also provided with blow cylinder 4, one end of described blow cylinder 4 connects impact bar 10, and described impact bar 10 is driven by blow cylinder 4 and can be inserted in copper pipe thus extrude expanding by the tip side of copper pipe.
Because aluminum pipe is general thicker, copper pipe is thinner, and the external diameter of two pipes is makeed an appointment, and therefore, needs first by the tip side undergauge of copper pipe, thus enables copper pipe be inserted into aluminum pipe inside and weld.
Described traveling electrode seat 6 is fixed on below aluminum pipe top mold frame 5, arranges aluminum pipe clamping cylinder 1 above described aluminum pipe top mold frame 5.Described copper pipe clamping 9 comprises upper clamp formwork, lower clamp formwork, the opposite face of upper lower clamp formwork is symmetrical arranged respectively the half slot for holding copper pipe, and the top of upper clamp formwork is provided with copper pipe clamping cylinder 2.
The end of described impact bar 10 is spherical top guide, and top guide plays the effect guiding and insert, and the diameter of top guide is less than the minimum diameter of copper pipe joint end.
See Fig. 2, due to copper pipe 12, the external diameter of aluminum pipe 11 is makeed an appointment, aluminum pipe 11 is thicker than copper pipe 12, therefore, the internal diameter Φ A of aluminum pipe 11 is less than the internal diameter Φ B of copper pipe 12, the tip side of copper pipe first uses heading machine undergauge, the straight length 14 making it form one section of external diameter to be less than aluminum pipe internal diameter, with outside one section, the undergauge section that internal diameter gradually changes, slightly larger than aluminum pipe internal diameter Φ A therefore the diameter of phi C of the active section of impact bar is designed to be less than copper pipe internal diameter Φ B and by we, when the tip side that impact bar impacts copper pipe is expanding, it can by the regional area impact extruded of copper pipe undergauge section, thus form the welding extruded segment 13 that one section of internal diameter is Φ C, in the expanding process developed, due to the active force of impact bar, make copper, aluminum pipe is squeezed, thus by the oxide layer of aluminum pipe inner wall surface, or copper aluminium eutectic structure is extruded by high pressure, form the copper-aluminium joint that adhesion is stronger, solve the problem of soldering reliability.
Above-mentioned specific embodiment is only the good detailed description of the invention of the utility model effect, does not form restriction of the present utility model, allly does simple conversion person without creative work to the design of the utility model, all belongs in the protection domain of the application.
