The presser feet of computerized emboridering machine is all generally combine by being equipped with many root lengths pin bar and corresponding supporting upper dead point block and bottom dead centre block on an independent pin bridge, owing to existing pin bridge is one-piece construction, requirement on machining accuracy is caused to become high, and the rigidity decrease in strength of minute hand bar, the comparison become when thick fabric embroidered by embroidery machine is difficult, abrasion strengthens, it is easy to broken needle.
Owing to pin bridge adopts split structure, adopting short pin bar, structure is more reasonable simultaneously, when the upper and lower stroke of pin bar is constant, shortening pin pole length (shorten 42.5%) makes pin bar intensity under the constant prerequisite of diameter improve, and abrasion reduces, and precision improves. Owing to original pin bridge is split into two pieces of parts, it is divided into major parts and minor components to make processing with different materials respectively, component costs can be effectively reduced like this, it is to increase component processing precision and work-ing life.
Concrete, the aluminum alloy materials of the added general use 6061-T6 of pin bridge, pin bridge undercarriage uses the aluminum alloy materials of 7075-T6, this bi-material differs 57% in mechanical property, the material hardness of 6061-T6 is generally between 90-95HB, 7075-T6 material hardness is between 150HB, and simultaneously both prices differ about 50 pieces/kilogram, therefore can effectively reduce costs.
Process separately the front-rear center comparison of coherence to all needle bar holes with hour hands bridge undercarriage to control well, it is possible to bring up between 0.01 to 0.02 by the precision of original 0.03 millimeter. The processing length of single needle bar hole shortens to 36 millimeters by original 120 millimeters simultaneously. Such pin hole adds the verticality in man-hour, and it is meticulousr that circularity and smooth finish equally accurate just can control.
Each upper dead point of pin bridge of the prior art to be gone debugging one by one, in the utility model, upper dead point limiting plate 34 is fixed by two ends screw, as long as the upper dead point that the screw at adjustment two ends just can reserve all pin bars on single pin bridge is spacing, save the time, it is to increase efficiency.
This just causes pin bar return spring can only be contained in pin bar top independent presser feet and presser feet spring on each minute hand bar on each pin bridge existing, and bottom is used for dress presser feet spring. Now owing to adopting independent presser feet, presser feet is separated with pin bar, a head only presser feet, and presser feet is contained on machine shell by being originally contained on pin bridge instead, the return spring on such pin bar top can move pin bar bottom, simultaneously minute hand bar upper section just can truncate, and the circularity of short pin bar and the precision beated are adding can control man-hour meticulousr simultaneously. This structure can well complete the moving process of pin bar thorn cloth, increases pin bar thorn cloth effect, it is to increase the rigidity intensity of pin bar, reduces friction and improves the working efficiency that pin bar stings thick fabric simultaneously. Reduce the processing request of pin bridge, it is to increase working efficiency.
