The key body is molded by an iron sheet or stainless steel or stainless iron with thickness ranging from 0.5mm to 0.7mm via stamping, the section of the key body is U-shaped, two edges of the U-shaped body are respectively provided with bits in different shapes, and the hilt is connected with the body via injection molding.

Description

Key with two rows of teeth

Technical field

The utility model relates to a kind of key with two rows of teeth, and relating in particular to a kind of cross sectional shape by stainless steel or stainless iron or iron stamped from sheetstock moulding is the key with two rows of teeth of U-shaped shape.

Background technology

Key safety with double rows of teeth is good, uses increasingly extensive.Make by copper material with the key with two rows of teeth that the utility model is approaching,, mill out groove with corresponding lock core coupling, then with carving operation such as double rows of teeth on the computer tooth cutter at milling machine through the blanking stamp.There is following defective in the key with two rows of teeth of above-mentioned moulding: rupture easily when 1, the key of making of copper material uses.2, adopt the milling machine machined grooves, need the thicker sheet material of thickness, and, mill off lot of materials, waste resource.3, need equipment many, processing trouble, the processing of incompatibility stainless steel material.

Summary of the invention

Technical problem to be solved in the utility model is: provide that a kind of intensity is good, material is economized, the simple key with two rows of teeth of processing method.

The technical scheme that the utility model adopted is: a kind of key with two rows of teeth, comprise shank and key body, it is characterized in that: described key body is iron sheet or the stainless steel or the stainless iron punch forming of 0.5-0.7 millimeter by thickness, its cross sectional shape is the U-shaped shape, top, described U-shaped shape body both sides is respectively equipped with the tooth of dissimilar tooth form, and described shank connects by injection mo(u)lding and with body.

The beneficial effects of the utility model: 1, good than copper material key intensity, frangibility not; 2, processing method is simple, economical with materials, and use equipment is single, and processing cost is low.

The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the left view of Fig. 1;

Fig. 4 is the rear elevation of Fig. 1;

Fig. 5 is a key with two rows of teeth body preparation method process chart.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, embodiment illustrated in fig. 4, comprise shank 1 and body 2, body 2 is stainless steel or the stainless iron or the iron stamped from sheetstock moulding of 0.5-0.7 millimeter by thickness, preferably adopts stainless steel, prevents long getting rusty easily service time.Body 2 cross sectional shapes are U-shaped shape 4, and described U-shaped shape body dual-side top is respectively equipped with the tooth 3 of dissimilar tooth form and tooth depth, and described shank 1 glueds joint or the interlocking one by injection mo(u)lding and with body 2.

The preparation method of described key with two rows of teeth body is characterized in that comprising following operation:

(1), blanking: stainless steel or stainless iron or iron sheet material are become the body plane blank by the design size blanking on common punch press;

(2), towards tooth: body plane blank front part sides limit is disposable towards profile of tooth by designing requirement on common punch press, and formation has the body plane blank of two toothrows;

(3), moulding: the body plane blank that will have two toothrows is placed on the punch press that is provided with the U-shaped convex mold and pushes, and forming cross sectional shape is the key body of U-shaped.

With the key handle part of the key body of moulding and injection mo(u)lding glued joint one one key with two rows of teeth.

Claims

1. key with two rows of teeth, comprise shank and body, it is characterized in that: described body is stainless steel or the stainless iron or the iron stamped from sheetstock moulding of 0.5-0.7 millimeter by thickness, its cross sectional shape is the U-shaped shape, described U-shaped shape body dual-side top is respectively equipped with the tooth of dissimilar tooth form and tooth depth, and described shank connects by injection mo(u)lding and with body.
