Abstract
The utility model discloses a cobwebbing wire drawing die which comprises the wire drawing die and a rotation die sleeve assembly, wherein the wire drawing die is provided with a drawing hole; the rotation die sleeve assembly comprises a base and a die sleeve which is rotationally sleeved in the base; and the wire drawing die is arranged in the die sleeve. The cobwebbing wire drawing die is matched with lace bars for drawing manufacturing, and has the characteristics of simple structure and flexible operation.
Description
Technical field
The utility model relates to drawing die, especially a kind of reticulate pattern wire-drawing die that is used for copper alloy bar.
Background technology
Brass alloy rod is widely used in industries such as air-conditioning, automobile, hot-water heating, and wherein the part brass bar need be processed as bolt, nut, and this has the frictional force requirement to the bar surface; Or because of outer bar surface needs through plastic processing,, require the certain frictional force of bar surface needs equally, the raw material band that wraps with fixed packet for avoiding coming off of raw material band.In order to increase the skin-friction force of bar, the bar Surface Machining of being everlasting goes out certain lines, to improve the surface roughness of product.Method commonly used has: hot melt, hot pressing, ultrasonic fusing and injection moulding are pre-buried etc., make the tight interlock of product and plastic parts, play connection, lock fastening effect.
Because the user adopts conventional annular knurl rod that the degumming quality problem often takes place, and common ledrite receives the influence of lead contamination not meet environmental requirement, and product can not export American-European developed country.For this reason, those skilled in the art have developed unleaded outer sharp high tooth lace brass alloy rod, meet viscose glue property and environmental requirement.Lace bar surface is reticulate pattern, and the positive left-hand thread that can be considered bull is present on the bar simultaneously; In the pulling process of lace bar, bar, mould the two have only needs to rotate, but because of the bar head needs under the pulling force of stretching dolly, draw through mould, can't rotate, and therefore needs special wire-drawing die cooperate drawing.
Summary of the invention
The utility model problem to be solved just provides a kind of reticulate pattern wire-drawing die, is used for the drawing of lace bar, has characteristics simple in structure, flexible operation.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of reticulate pattern wire-drawing die; It is characterized in that: comprise the wire drawing die and the rotation die sleeve assembly that have stretchable holes; Said rotation die sleeve assembly comprises that base and turning set are contained in the inherent die sleeve of base, and said wire drawing die is installed in the die sleeve.
Further, said wire drawing die is made up of wire drawing die sleeve and the wire drawing internal mold that is inlaid in the wire drawing die sleeve, and said wire drawing die puts and is provided with scallop, and the wire drawing internal mold is provided with pilot hole, and described stretchable holes is put together by scallop and pilot hole.
Further, said pilot hole inner wall even distribution has some oblique tooth trace guide grooves.Guarantee bar after drawing, surperficial profile of tooth is satisfactory spiral lamination.
Further, the tooth in the said scallop is designed to sharp high tooth.
Further, said die sleeve and base are rotationally connected through bearing part.
Further, said bearing part is pressure-loaded bearing or cone bearing.
Further, be provided with the location structure that limit mold is overlapped axial displacement between said die sleeve and base.
Further, said location structure comprises the positioning retainer ring that is installed on die sleeve one end, and base is provided with the positioning step that offsets with positioning retainer ring.
Further, said base is pressing plate type base or tapered sleeve type base.
The beneficial effect of the utility model: the utility model is simple in structure, mould is easy to assembly, rotate nimbly and freely; Can design according to profile of tooth, the reticulate pattern gradient that bar requires, guarantee the gradient of bar reticulate pattern, improve the surface roughness of lace bar.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model wire drawing die;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation one of the utility model rotation die sleeve assembly;
Fig. 4 is the assembling sketch map of the utility model;
Fig. 5 is the structural representation two of the utility model rotation die sleeve assembly.
The specific embodiment
With reference to Fig. 1-4, a kind of reticulate pattern wire-drawing die comprises the wire drawing die and the rotation die sleeve assembly that have stretchable holes, and said rotation die sleeve assembly comprises that base 3 and turning set are contained in base 3 inherent die sleeves 4, and said wire drawing die is installed in the die sleeve 4.Wire drawing die is made up of wire drawing die sleeve 1 and the wire drawing internal mold 2 that is inlaid in the wire drawing die sleeve 1, and said wire drawing die sleeve 1 is provided with scallop 11, and wire drawing internal mold 2 is provided with pilot hole 21, and described stretchable holes is put together by scallop 11 and pilot hole 21; Pilot hole 21 inner wall even distributions have some oblique tooth trace guide grooves 22, guarantee bar after drawing, and surperficial profile of tooth is satisfactory spiral lamination, and the tooth in the scallop 11 is designed to sharp high tooth.
Die sleeve 4 is rotationally connected through bearing part 5 with base 3, and bearing part 5 can be selected pressure-loaded bearing or cone bearing for use according to the drawing process of mould.3 of die sleeve 4 and bases are provided with the location structure of restriction die sleeve 4 axial displacements, and location structure comprises the positioning retainer ring 6 that is installed on die sleeve 4 one ends, and base 3 is provided with the positioning step 31 that offsets with positioning retainer ring 6.Except pressing plate type base shown in Figure 4, base also can be selected tapered sleeve type base as shown in Figure 5 for use.
Wire drawing die should design according to profile of tooth, the reticulate pattern gradient that bar requires, and guarantees the gradient of bar reticulate pattern, improves the surface roughness of lace bar.Because of lace bar surface is reticulate pattern, the positive left-hand thread that can be considered bull is present on the bar simultaneously, and during so actual the drawing, wire drawing die should be equipped with two covers, and the groove of stretchable holes is in the opposite direction in the two cover wire drawing dies.
