The specific embodiment
In order to describe structure of the present invention and feature place in detail, hereby lift following preferred embodiment and coordinate graphic explanation as after, wherein:
As shown in Figures 1 to 6, a kind of metal housing that a preferred embodiment of the present invention provides and the welding method of plate body, consist predominantly of the following step:
A) as shown in Figure 1, purchase an outer cover 11 and a plate body 21, this outer cover 11 is metal material, and having a periphery 12 can be for welding.
B), in the mode corresponding to these outer cover 11 peripheries 12, on this plate body 21, be coated with suitable thickness and width and be banded wlding 22.In the present embodiment, this wlding 22 encloses and is a shaped as frame.But, be not in fact limited with shaped as frame.
C) as shown in Figure 2, this outer cover 11 be placed on to this plate body 21 and the periphery 12 of this outer cover 11 is pressed against on this wlding 22, and forming semi-finished product 29, and these semi-finished product 29 are placed on tool 31; On the implementation, can first this outer cover 11 be placed on to this plate body 21 and be placed in again on this lower tool 31 after forming these semi-finished product 29, or also can first this outer cover 11 be placed on this lower tool 31 and make this periphery 12 upward after, then this plate body 21 is placed on to this outer cover 11, in figure, be take the latter as example; This lower tool 31 provides the supporting role to these semi-finished product 29, and has an enclosure wall 32 around this plate body 21 and this outer cover 11 around, and in order to provide limit effect to this plate body 21 and this outer cover 11, wherein this enclosure wall 32 is non-metallic material.In the present embodiment, periphery 12 outer rims of this outer cover 11 are alignd with the outer rim of this plate body 21, and this enclosure wall 32 clips slightly in the outer rim of these plate body 21 outer rims and this outer cover 11.In addition, in the present embodiment, the outer rim of this wlding 22 is aligned in periphery 12 outer rims of this outer cover 11, and the width of this wlding 22 is greater than periphery 12 thickness of this outer cover 11, and the inner edge of this wlding 22 is positioned at the region that the periphery 12 of this outer cover 11 encloses whereby.Aforesaid only clipping as use for example, not to clip as necessity, does not only clip while being related to for enclosing, and still has spacing effect.
D) if Fig. 3 (A) is to as shown in Fig. 3 (C), make this lower tool 31 rise or decline and adjust height, and then these semi-finished product 29 are entered in the induction coil 41 of a heater together with this enclosure wall 32, in the present embodiment, make the centre-height of this induction coil 41 and the faying face of this outer cover 11 and plate body 21 with high, and make tool 35 on be pressed against plate body 21 tops of these semi-finished product 29.In the present embodiment, make this lower tool 31 increase, and these semi-finished product 29 are entered in this induction coil 41 from lower to upper.In addition, as shown in Figure 4, also make be separated by a space G and do not contact between this induction coil 41 and this outer cover 11 and this enclosure wall 32.The faying face of the centre-height of aforesaid induction coil 41 and this outer cover 11 and plate body 21 is with high, in order to make the heating effect of this induction coil 41 best, but, this case can also be different high and weaker height (for example differing 1～2 millimeter) only, just heating effect can be weaker, but still can reach the effect of heating.
E) operating this heater makes this induction coil 41 produce concussion electric current in a scheduled time and predetermined power, and then these outer cover 11 peripheries 12 being heated to exceed than this wlding 22 fusing points the temperature of 20 degree～100 degree Celsius, this wlding 22 melts and is filled in the gap between this outer cover 11 and this plate body 21.In the present embodiment, obtaining of this scheduled time and this predetermined power, to carry out abovementioned steps A with reference to plate body 21 and with reference to outer cover 11 with one)～D) action, selected after a free power by operator, make this induction coil 41 according to this free power heating, and with the temperature of this outer cover 11 of sensor (not shown) sensing, and then the temperature arrival that obtains this outer cover 11 is spent the required heat time as this scheduled time higher than 20 degree～100 of these wlding 22 fusing points, obtain whereby this predetermined power and this scheduled time, and by this free power as this predetermined power.And
F) to be cooledly after solidifying, this wlding 22 completes welding.When cooling, can be positioned under room temperature and wait for that it is naturally cooling carrying out, also can use at least one air-source 38 to blow and drop a hint to this space G, so as to improving cooling rate.As shown in 5 figure, in the time using air-source 38, take two air-sources 38 as example, lay respectively at the opposite side of these semi-finished product 29.In addition, this air-source 38 blows the air of putting, and can be the air of room temperature, can be also the air of low temperature, can be also specific gas and air can be general atmosphere, for example nitrogen.This air-source 38 can be fan or air jet pipe.
Must remark additionally, in abovementioned steps A) or step B) in, more can be coated with scaling powder 14 in this periphery 12, and then make welding process more smooth, welding result is better.But, be not coated with scaling powder also can, the not necessary technology take scaling powder as this case.
The steps A that abovementioned steps discloses)～F), be relevant part of welding, and after welding completes, can make tool 35 increase and lower tool 31 declines, the finished product that user can complete welding takes off on this lower tool 31.
Abovementioned steps E) in, due to the region that is positioned at the periphery 12 of this outer cover 11 within this wlding 22 and encloses, therefore when in heating process, this wlding 22 melts, as shown in Figure 6, this wlding 22 can because of surface tension so climb up periphery 12 internal face one predetermined altitudes of this outer cover 11, after solidifying, can reach better welding effect.But, if while making the width of this wlding 22 identical with the thickness of these outer cover 11 peripheries 12, though do not have aforesaid wlding 22 to climb up the effect of these periphery 12 inwalls, only still there is the effect in the gap between this outer cover 11 of filling and this plate body 21, be still enough to the welding effect that reaches good.
In addition, in previous embodiment, the outer rim of this plate body 21 is aligned in the periphery outer rim of this outer cover 11, but is in fact not limited thereto.As shown in Figure 7, this plate body 21 ' is slightly larger than the region that the periphery 12 ' of this outer cover 11 ' encloses, the width of this wlding 22 ' is greater than the periphery 12 ' thickness of this outer cover 11 ', the inner edge of this wlding 22 ' is positioned at the region that the periphery 12 ' of this outer cover 11 ' encloses whereby, and the outer rim of this wlding 22 ' is positioned at the periphery 12 ' outside of this outer cover 11 '.Therefore, when in heating process, this wlding 22 ' melts, this wlding 22 can because of surface tension so climb up periphery 12 ' internal face and outside wall surface one predetermined altitude of this outer cover 11 ', that is, all there is the effect of climbing tin two sides at this periphery 12 ', can reach better welding effect after solidifying.
As from the foregoing, the attainable effect of the present invention is:
One, the temperature can control heating time, avoids because temperature factor causes the problem of defective products.
Two, by this lower tool, can make to form positioning relation between outer cover and plate body in welding process, make the process of welding more stable, welding result is more accurate.
