Description
The present invention relates to the manufacturing process of micro-special-shaped contact web, the combined positioning method the when micro-special-shaped contact web of more specifically saying so is made.
Micro-special-shaped contact web is a kind of MULTILAYER COMPOSITE, cross section less than 1 square millimeter band, wherein has a kind of noble metal or precious metal alloys in the clad material at least.It is widely used in the small-sized or microminiature electronic product such as relay, switch, keyboard switch.
The method of making micro-special-shaped contact web has multiple: galvanoplastic, brush plating method, vapour deposition method, magnetron sputtering, rolling compound and welding is compound etc.It is more effective having rolling compound and roll welding compound in continuously compound.But to consider compound orientation problem at compound tense.Combined positioning method has direct relation with the complex method of material shape and use.Wherein having and a kind ofly rollingly inlay compoundly, is base material to be driven a dovetail groove make its location, makes two kinds of materials be able to compound at heavy reduction.
Roll welding in the technology of making micro-special-shaped contact web is compound to be to be taken turns 1 by the pair of electrodes weldering continuously by compound material overlying strata material (going up band) 2 and following clad material (following band) 3, with two kinds of mutual seam of material, to form composite 8 by resistance heat.Entered continuous seam welder electrode weldering at two kinds by compound material and took turns before 1, install a positioner 4 additional, see Fig. 1, the cross-sectional view of positioner as shown in Figure 2.Positioner is made of last location-plate 5 and following location-plate 6.Middle for entering the space, location of two kinds of composites treating that roll welding is compound.This localization method is the preposition positioning mode of welding machine.
By the center deviation of compound upper and lower band is that deviation of centre distance value δ is a yardstick of weighing the quality of location, sees Fig. 3.
The above-mentioned preposition localization method of this welding machine also will have certain space that material can be passed through in the centre because upper and lower location-plate machine-building has certain tolerance, secondly also has wearing and tearing in use, makes size become big.Such positioning accuracy just can not be high, when treat compound material in the space of location by the time, treat that compound upper and lower band may swing in the horizontal direction and cause upper and lower layer by compound material production dislocation.The positioning accuracy of this localization method is to meet the requirements of for large-sized composite or required precision when not high.The deviation of centre distance value δ of this localization method＞0.05 millimeter is 0.1 millimeter to the maximum.And the deviation of the direct fluting localization method on the another kind of electrode welder weldering wheel is 0.2 millimeter to the maximum, and obviously preceding a kind of localization method is better than the fluting location of electrode welder weldering wheel.
Because the micro-special-shaped contact web size is little, the precision height can not align after can making upper and lower band compound with the preposition positioning mode of welding machine, and the magnitude of misalignment on width is not only big, and magnitude of misalignment causes the not of uniform size of length direction, makes that technical process is difficult to control.
Purpose of the present invention just is to work out under the situation of the upper and lower location-plate that does not change the preposition positioner of equipment complex, make that the dislocation of upper and lower clad material (upper and lower band) is little, improve the combined positioning method of a kind of new micro-special-shaped contact web manufacturing of compound precision.
In order to reduce the deviations between the upper and lower band of the compound or rolling compound tense of continuous roll welding, its technical method is to adopt to install a positioner additional before being entered equipment complex by compound material, positioner itself be there is no improvement, but, make deviations be reduced to minimum with the shape change of composite.
The combined positioning method that a kind of micro-special-shaped contact web of the present invention is made, what treat to install additional before compound band enters equipment complex, one by last location-plate, before the positioner that following location-plate constitutes, to treat that compound last band is processed into the profile shapes that has at least to lead a muscle, following band is processed into has at least its position and last band to lead a profile shapes of the corresponding position guiding groove of muscle, to have to have a last band of leading a muscle at least and have the following band that has at least its position and last band to lead a corresponding position guiding groove of muscle and carry out compound prelocalization, enter the space, location in the positioner, again with on oriented, following band send into carry out in the equipment complex compound.
