Abstract
The utility model discloses an improved structure of a wire-drawing die. The improved structure of the wire-drawing die comprises a die sleeve and a die core sleeved in a central hole of the die sleeve, wherein an annular projection is arranged at the bottom of the central hole of the die sleeve and is used for blocking the die core; and a blocking side for preventing the die core from slipping off is arranged on the top of the central hole of the die sleeve. In the utility model, the annular projection is arranged at the bottom of the central hole of the die sleeve and is used for blocking the die core, and the blocking side is arranged on the top of the central hole of the die sleeve, so the die core can be prevented from dropping off and slipping off the top of the central hole of the die sleeve.
Description
Technical field
The utility model relates to wire-drawing die.
Background technology
In stress metal processing, make metal by force through mould under external force, metal cross section is long-pending to be compressed, and the instrument that obtains desired cross-sectional area shape and size is called wire drawing die.The patent No. is that 93206303.9 Chinese utility model patent discloses a kind of linear cold drawn wire mould on May 18th, 1994.This mould comprises die sleeve and core rod, and core rod is located in the die sleeve centre bore and die sleeve centre bore bottom is provided with annular protrusion and keeps out core rod, but this structure core rod comes off from die sleeve centre bore top easily and skids off.
The utility model content
The utility model technical problem to be solved just provides a kind of wire-drawing die of avoiding core rod to come off and skid off from die sleeve centre bore top.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of wire-drawing die improves structure; Comprise die sleeve and be set in the core rod in the die sleeve centre bore; It is characterized in that: said die sleeve centre bore bottom is provided with annular protrusion and keeps out core rod, and said die sleeve centre bore top is provided with the rib that prevents that core rod from skidding off.
Preferably, said die sleeve centre bore bottom is provided with tapered opening, and said annular protrusion is located at said tapered opening bottom.
Preferably, said core rod and said die sleeve centre bore are interference fit.
Preferably, said core rod endoporus comprises arcuate guide district and column shaping area.
The utility model is provided with annular protrusion and keeps out core rod and be provided with rib at die sleeve centre bore top simultaneously in die sleeve centre bore bottom, thereby can avoid core rod to come off from die sleeve centre bore top skidding off.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; For a kind of wire-drawing die of the utility model improves structure; Comprise die sleeve 1 and be set in the core rod 2 in the die sleeve centre bore, said die sleeve centre bore bottom is provided with annular protrusion 12 and keeps out core rod, and said die sleeve centre bore top is provided with the rib 13 that prevents that core rod from skidding off.Said die sleeve centre bore bottom is provided with tapered opening 11, and said annular protrusion is located at said tapered opening bottom.Said core rod and said die sleeve centre bore are interference fit.Said core rod endoporus comprises arcuate guide district 21 and column shaping area 22.
The embedding grammar of core rod does, at first core rod is pressed into from the die sleeve top, forms rib through the mould extruding then, and rib also can be connected with die sleeve for forms such as welding certainly.
