With the tin melt-blended of the lead and the 5-7 weight portion of 3-5 weight portion, fusion temperature 180-280 ℃.
2, the wire surface oxide is removed
To put into that the zinc chloride saturated aqueous solution soaks or with hairbrush brushing zinc chloride saturated aqueous solution on tiling copper wire pad.
3, copper wire pad immersed solder material
The tiling copper wire pad of completing steps 2 is put into the scolder of fusion up,, pull out after making the copper wire pad soak the full weld material to there not being bubble.
4, base steel is hung scolder
Base steel is put into heating furnace be heated to 200-300 ℃, base steel is moved on the hydraulic press, hang one deck scolder on the base steel surface corresponding again with tiling.
5, seam
The tiling of completing steps 3 is placed on the base steel of completing steps 4, remains on the 1-8MPa that pressurizes under the temperature that is enough to melt the scolder in the copper wire pad, pressurize naturally cools to below 130 ℃, accomplishes tiling and welds with the soldering of base steel.
More than each step optimum process condition be:
The optimum amount ratio of the lead of step 1 and tin is plumbous 4 weight portions, tin 6 weight portions.Heating-up temperature 200-210 ℃.
Base steel heating-up temperature in the step 4 is 250-270 ℃.
The pressure of seam pressurization is 3-58MPa in the step 5.
Good effect of the present invention is that to provide a kind of welding abundant, and weld seam does not have the high elastic metal plastic bearing tiling of interlayer, tiling and base steel bond strength and the method for welding of base steel, standard the welding procedure of soldering of elastic metal plastic bearing tiling and base steel.
The specific embodiment
1, makes the elasticity of plastics tiling
(1) tin bronze wire with diameter 0.4mm is wound in spring closely on 28 inches bicycle spoke, again with its stretching open to spring base and diameter about equally.Spring after stretching is cut into the long spring section of 45-90mm, is sprinkling upon in the mould, hit tight gently after the capacity to the degree formation wire pads blank that can not be scattered while cutting.The depanning parcel is subsequent use.Blank of spring is put as in the die of going into the hydraulic press mould, pulled out punch when the pressurization punch makes porosity reach 50-70% and form wire pads, spread the modified polytetrafluoroethylresin resin powder of sneaking into filler on the wire pads in die; The pressurization punch is to the 25-55MPa moulding; Pull out punch immediately, take out the moulding tiling and put into vacuum drying oven vacuum-sintering, vacuum is 5-20pa; Sintering temperature 350-380 ℃, constant temperature 15-60 minute.Naturally cool to 120 ℃ of making of promptly accomplishing tiling.The filler that joins in the resin-oatmeal can be enhancing, antifriction material a kind of or several mixing wherein such as copper powder, lead powder, carbon fiber, glass fibre, polyphenyl fat, graphite, molybdenum bisuphide.
2, make base steel
Adopt common mechanical technology to accomplish by the shape of setting, size.
3, scolder preparation
With the tin melt-blended of the lead and 6 weight portions of 4 weight portions, fusion temperature 200-210 ℃.
4, the wire surface oxide is removed
To put into that the zinc chloride saturated aqueous solution soaks or with hairbrush brushing zinc chloride saturated aqueous solution on tiling copper wire pad.
5, copper wire pad immersed solder material
The tiling copper wire pad of completing steps 2 is put into the scolder of fusion up,, pull out after making the copper wire pad soak the full weld material to there not being bubble.
6, base steel is hung scolder
Base steel is put into heating furnace be heated to 250-270 ℃, base steel is moved on the hydraulic press, hang one deck scolder on the base steel surface corresponding again with tiling.
