Description

Clothing scissors

The utility model belongs to crop tool.

The clothes scissors of fabrics such as cutting cotton, silk, woollen goods, be by greatly cut strand (Fig. 2) and wisp cut thigh (Fig. 4) through spring washer A, cut a B, packing ring C, E and nut D assemble (Fig. 1).Cutting thigh is by cutting 1(Fig. 2,4) and haircut 2(Fig. 2,4) constitute.Cut in the past and haircut be by two kinds of different cast steels through cast, operation manufacturings such as rolling, welding, quenching form.Promptly cut adopting A3 cast steel, haircut is then by the steel of A3 cast steel and two kinds of materials of 65Mn cast steel, through rolling, forge again with cut cutting through being welded strand whole.Product manufacturing process complexity, stock utilization only 48%, haircut quenching area is big, needs all to handle.Now improve at the problems referred to above.

The utility model characteristics only adopt a kind of material steel, promptly use 65Mn cast steel to cut the casting of strand Integratively and form large and small respectively, re-use to cut axle, spring washer, packing ring and nut and assemble.Technology for Heating Processing only needs the cutting edge position F(Fig. 1 to haircut) carry out Quenching Treatment, the width 7mm of quenching has reduced quenching area in the past.810～830 ℃ of hardening heats, 180～200 ℃ of temperatures, tempering time 30 minutes.The cutting edge hardness number is HRC54～62.Product quality meets China's ministry standard.Because adopt a kind of material steel, the production operation has reduced 1/2, stock utilization improves more than 80% simultaneously, makes cost decreases.

Another characteristics of the present utility model are to cut 1(Fig. 3 what wisp was cut strand) locate to be added with nurse and contribute supporting surface G(Fig. 3), improves downward pressure, can make when cutting out fabric Sheng Li And and stablize.Use the scissors of 65Mn cast steel Integratively casting, but the overlapping nine layers of cotton of cutting, and phenomenons such as chipping, turned, hinge mouth do not take place in cutting edge.And all can reach and cut to the end.

Product specification is 7 inch～12 inch.
