Abstract
The forming process includes the steps of integral forming to form the front piece of shuttle, ramming to form the rear piece of shuttle, welding to combine the said front piece and the said rear piece, and welding to fix the shuttle shaft machined through once machining in automatic lathe onto the rear piece. The said process can raise production efficiency of semi-rotary shuttle and raise its quality.
Description
The present invention relates to a kind of manufacture method of shuttle of Sewing machines, particularly relate to a kind of manufacture method of semi-rotary shuttle for sewing machine moulding.
As shown in Figure 1, general semi-rotary shuttle that Sewing machines uses 10 comprises last slice part 11, a middle sheet spare 12, a following sheet spare 13 and a shuttle axle 14, at this last, form an accommodation space 15 between a part 11 and the following sheet spare 13, can be for putting bobbin (figure does not show), the tip of sheet spare 12 forms a bill portion 121 in this, because this semi-rotary shuttle 10 is housings of a curved arc shape, and this bill portion 121 is a pointed shape, so manufacture of general semi-rotary shuttle 10, be that this semi-rotary shuttle 10 is divided into last slice part 11 mostly, middle sheet spare 12, following sheet spare 13 and shuttle axle 14, said modules is respectively with after the moulding of modes such as punching press and turning difference, again through welding, welding and grinding etc. just can be finished goods after repeatedly processing, but, because the bill portion 121 of sheet spare 12 is pointed shape in being somebody's turn to do, so turning repeatedly, mill and grind secondary processing process, up to meeting required size, specification, therefore, in process, not only time-consuming, consumption power, and because deform easily in the complicated process, the coarse defective products of size, cause the loss of making on producing, and make cost increase.
The object of the present invention is to provide a kind of manufacture method of semi-rotary shuttle for sewing machine moulding, shuttle body back segment spare by integrated shuttle body leading portion spare and impact style moulding is welded again, welding, the semi-rotary shuttle that is obtained, the effect of raising the efficiency, saving man-hour except having has more and improves stay in grade degree and the advantage that reduces fraction defective.
The manufacture method of semi-rotary shuttle for sewing machine moulding of the present invention comprises the following steps:
One, the moulding of shuttle body leading portion spare: one-body molded in the metal ejection formation mode, and grind through the in addition thin again portion of dewaxing, vacuum-sintering and to form a shuttle body leading portion spare, the bottom inner edge of this shuttle body leading portion spare just forms a terrace when one-body molded;
Two, the moulding of shuttle body back segment spare: with continuous punch forming one shuttle body back segment spare, the top of this shuttle body back segment spare forms a faying surface in this terrace corresponding section;
Three, the moulding of shuttle axle: form a shuttle axle with the automatic lathe time processing;
Four, Combination Welding, welding are handled: the faying surface of this shuttle body back segment spare is overlapped on the terrace of this shuttle body leading portion spare, make its location after again with the welding manner driving fit, and put in vacuum welding stove and do the copper welding, at last, again this shuttle axle is welded on this shuttle body back segment spare, and obtains the high semi-rotary shuttle of quality stability.
Effect of the present invention and advantage be as described later:
1, because this shuttle body leading portion spare 20 of the present invention is one-body molded and do not need the repetitiousness car, mill with injection molding method, so these bill portion 22 specifications, dimensionally stable, and smoothness is good, therefore, the advantage of raising the efficiency, saving manpower, man-hour except having more can improve the stay in grade degree of product and reduce fraction defective.
2, because the corresponding section, top of these shuttle body leading portion spare 20 bottoms of the present invention and shuttle body back segment spare 30 is respectively equipped with this terrace 23 and faying surface 31, can overlap usefulness, when this shuttle body leading portion spare 20 and shuttle body back segment spare 30 in Combination Welding, when welding is handled, have convenient location and strengthen the welding effect, make finished product more stable.
In sum, the manufacture method of semi-rotary shuttle for sewing machine moulding of the present invention has the effect of raising the efficiency, saving man-hour, and has the advantage that improves the stay in grade degree and reduce fraction defective.
The present invention is described in detail below in conjunction with drawings and Examples:
