Technical Field
The utility model relates to a screw processing technology field, more specifically say, it relates to a novel wear-resisting screw stamping die.
Background
The die is a tool for making a molded article, and when making a screw, a die-casting die is one of the tools commonly used for making a screw, and the die-casting is a method for obtaining a casting by filling a die cavity of the die-casting die with a liquid or semi-liquid metal at a high speed under the action of a high pressure and rapidly solidifying under the pressure. For a die to be subjected to press forming, it is generally required to have excellent rigidity and impact strength, and the die is less likely to crack or deform under repeated impact.
However, most of the existing traditional stamping dies adopt stainless steel or alloy steel as materials, and the dies made of the materials are easily oxidized at high temperature under the repeated impact of high strength, so that the surface quality of the dies is poor; and repeated impact has higher requirements on the wear resistance of the die, and if the wear resistance of the die is poor, the service life of the die is shorter.

In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides a novel wear-resisting screw stamping die, includes the mould body, the mould body includes the mould shell and arranges the mold core of mould shell central part in, set up screw shaping cavity in the mold core, two openings about screw shaping cavity has been seted up, the opening includes screw tip one-tenth die orifice and screw rod portion one-tenth die orifice, and screw tip one-tenth die orifice is the back taper opening with screw rod portion one-tenth die orifice, and the inner wall of screw tip one-tenth die orifice is seted up flutedly, the recess is annular evenly distributed and recess surface and is equipped with ceramic wear-resistant coating, and screw rod portion one-tenth die orifice department has seted up an annular groove, and fixed mounting has the reinforcing ring in the annular groove, the smooth and inner wall of screw shaping cavity inner wall is equipped with the wearing layer outward.
Further, the interior of the wear-resistant layer is filled with ceramic particle wear-resistant glue.
Still further, the recess outward flange is outside convex arc, and the recess is equipped with three altogether and is just regularly triangular and evenly arranges.
Still further, the outer diameter of the screw end forming opening is larger than the outer diameter of the screw rod stamping opening.
Furthermore, the mold core is made of tungsten steel, and the rest part of the mold shell is made of common steel materials.
Preferably, the outer wall of the formwork is provided with two cutting surfaces, the cutting surfaces are triangular and are arranged on the same side, the directions of the cutting surfaces are opposite, and arc-shaped threads are arranged on the cutting surfaces.
Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model adopts high-strength tungsten steel material as the mold core part, and adds a ceramic wear-resistant coating at the screw end forming port, adds a reinforcing ring at the screw rod part stamping port, and the inner wall of the screw forming cavity is provided with a wear-resistant layer which is filled with ceramic particle wear-resistant glue; the design of such wear-resisting structure is in order to strengthen the wearability of mould for the screw product quality that the mould punching press was come out is better and can improve the life of mould itself.

In the figure: 1-a mould shell; 2, a mold core; 3-forming a cavity by the screw; 4-forming an opening at the end part of the screw; 5-a groove; 6-punching a screw rod part; 7-a reinforcing ring; 8-cut surface.
Detailed Description
The following embodiments of the present invention will be further described with reference to the accompanying drawings 1-4.
The utility model provides a novel wear-resisting screw stamping die, which comprises a die body, the mould body includes metal mould shell 1 and arranges mold core 2 at 1 central part of metal mould shell in, screw shaping cavity 3 has been seted up in this mold core 2, two openings about screw shaping cavity 3 has been seted up, screw tip one-tenth die orifice 4 and the screw pole portion one-tenth die orifice 6 of lower extreme of upper end are respectively, screw tip one-tenth die orifice 4 is the back taper opening with screw pole portion one-tenth die orifice 6, the diameter size of interior port is less than the diameter size of outer port promptly, and screw tip one-tenth die orifice 4 external diameter is greater than the external diameter of screw pole portion one-tenth die orifice 6.
Because the screw tip needs the punching press line, consequently the inner wall of screw tip shaping mouth 4 is seted up fluted 5, and 5 outward flanges of recess are outside convex arc, and recess 5 is equipped with three altogether and just the whole combination is regular triangle form and evenly arranges, and a recess 5 position is arranged in regular triangle's an angle department promptly. Because the stamping die needs to be repeatedly stamped and needs to bear relatively frequent friction, the ceramic wear-resistant coating is arranged on the surface of the groove 5, and the coating can better protect the die to reduce the friction and prolong the service life of the die; simultaneously, the mould not only needs to have better frictional property, still have great intensity, consequently, an annular groove has been seted up in screw pole portion punching press mouth 6 department, fixed mounting has reinforcing ring 7 in the annular groove, this reinforcing ring 7, mold core 2 and mould shell 1 are integrated into one piece, can't dismantle promptly, and simultaneously, 3 inner walls of screw shaping cavity are smooth, are equipped with the one deck wearing layer outside the inner wall, in order to play better wear-resisting effect, this wearing layer is inside to be filled by ceramic particle wear-resistant glue. In order to achieve a better stamping effect and increase the strength of the die, the die core 2 is made of tungsten steel, and the rest part of the die shell 1 is made of common steel materials.
Because the mould can influence the effect and the quality of punching press because of moving when the punching press, consequently be equipped with two cutting planes 8 at the mould shell 1 outer wall, the design of this cutting plane 8 is in order to cooperate similar anchor clamps of other equipment etc. to clip the mould or fix in other modes, thereby the mould can not move at will at the in-process of punching press, and this cutting plane 8 is triangle-shaped and puts in same side and the direction is relative, still is equipped with the arc screw thread on cutting plane 8, the design of this arc screw thread is in order to increase frictional force.
The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
