Description
Technical field
The present invention relates to filament welding and mould applications, particularly relate to a kind of filament resistor housing soldering method and cover welding clamp.
Background technology
The method of current gas shield laser weld filament is in the placement welding region by filament after alignment, then carries out laser weld, and it is characterized in that welding job district must adopt gas shielded welding, its mechanical property is difficult to the requirement meeting mechanical property.
In prior art, two rhizoid parts are connected with tube, glue is used to be filled in pipe, then connect in two filament Inserting Tubes, well-known cementing strength is low, thus just lengthen casing length and wall thickness, there is the bond strength that cannot improve two seal wire portions, be difficult to the problem obtaining enough bending and torque transfer; Colleague tubular junction position increases the connecting length of two filaments, makes local diameter thicker; In addition there is the problem of connection operation this manufacture view troublesome of filament.
Current resistance welding procedures is: resistance is assembled into banjo fixing butt jointing to welded part, makes its end face close contact, applies rapidly upset force and completes welding, form firmly joint after utilizing resistance heat heating element to hot plastic state.But can only weld by the silk larger to diameter, upset butt welding is used for the manufacture of wire rolling factory and wirework, but for silk thin especially because the geometric accuracy of work pieces process and workpiece faying face adopts the mode of docking can not meet the various performance requirement such as bending strength and toughness.Adopt sleeve pipe to weld two rhizoids, because tube wall is very thin, welding process is very yielding, and joints changes, and joint quality is poor, and mechanical property can not meet instructions for use.
Summary of the invention
The present invention is directed to Problems existing in background technology, provide a kind of filament resistor housing soldering method and cover welding clamp, its concrete technical scheme is as follows:
A kind of filament resistor housing welding mould, is characterized in that: comprise insulating base (6), copper electrode plate (5), tantalum electrode plate (4), thin walled cylinder body (3), top cover (7); Described insulating base (6) is groove-like, and insulating base (6) one end is provided with copper electrode plate (5), and the other end is provided with tantalum electrode plate (4), and insulating base (6) top is provided with top cover (7); Described thin walled cylinder body (3) is through copper electrode plate (5) and tantalum electrode plate (4); Be full of cement in the space that described copper electrode plate (5), tantalum electrode plate (4) and top cover are formed, form cement testing blocks (8); Described copper electrode plate (5) is provided with conduction screw (10).
as preference:
Rubber sheet gasket (9) is provided with between described cement testing blocks (8) and top cover (7).
Described copper electrode plate (5) and tantalum electrode plate (4) are fixed kerve (12) respectively by insulating base and are fixed on insulating base (6).
Described top cover (7) is fixed on insulating base (6) by trip bolt (11).
Due to connected filament tiny especially (general diameter is less than 0.5mm), although very little assemblage gap, its expansion caused will cause the change of filament diameter significant proportion, need design a device and limit it in diametric expansion.Consider cement electrical insulating property, high temperature resistant, cheap and should be simply to use etc. feature, this mould adopts the mode of casting cement around thin walled cylinder body (3) to be formed into mould, the real cement of casting after shock dynamic pressure, then use rubber sheet gasket (9) to cover above cement block, and exceed the sidewall certain altitude on insulating base (6) both sides; Top cover (7) is covered, finally rubber sheet gasket (9) is pressed onto concordant with the sidewall on insulating base (6) both sides by top cover (7) again, thus the further whole cement block of compacting, then tightened the screw of fixed roof (7).Like this, whole cement block just forms certain compressive pre-stress to thin walled cylinder body (3).Expanding cement is set in thin wall casing outside, waits the expansion that can limit thin walled cylinder body (3) when solidifying rear welding, ensures the size of welding point.
When adopting resistance socket, certain upset force must be applied in two rhizoid ends, this just requires to apply upsetting force to two filaments, and must (otherwise easily push up partially when exerting pressure on an axis, thus cause property of welded joint to be deteriorated, even do not burn-on), that is, two filaments must on an axis.For addressing this problem, devise the thin walled cylinder body of outer wrap cement, silk welds in sleeve, sees Fig. 5.Apply upset force to two filaments during resistance socket, be easy to occur unstability, thin walled cylinder body and cement fixed block can ensure two filaments docking site destabilization problems when pressurized well.
