Abstract
The utility model category machine die accessory technical field, is related to a kind of pierce punch, and in particular to a kind of thread pierce punch.A kind of thread pierce punch of the utility model, the interior outer ram being overlapped including central axis, the outer ram is equipped with one end and is equipped with the central through hole for limiting interior convex, other end bottom end is equipped with along the outwardly projecting thread cutting edge of central through hole, described inner punch one end is positioning protrusion, the diameter that positioning protrusion diameter is greater than central through hole is less than the diameter for limiting interior convex, and the inner punch, which matches to merge with outer ram central through hole, stretches out thread cutting edge.The utility model can realize that punching is synchronous with stamping and carry out, and guarantee the verticality of thread；Tooth hole can be accurately positioned, guarantee the precision of product well, improve product quality；Procedure of processing is reduced, production efficiency is improved；Time processing forming, saves the time.
Description
Technical field
The utility model category machine die accessory technical field, is related to a kind of pierce punch, and in particular to a kind of thread punching
Hole formed punch.
Background technique
Currently, the threaded hole of sheet metal component is typically all after passing through formed punch punching, it is also necessary to take out semi-finished product manually to every
Device to hole tapping is manually operated in a hole, and such heavy dependence is artificial, and production efficiency is not high, secondly device to hole tapping again, deviations
It will affect the quality of product.
Utility model content
The purpose of this utility model is to provide a kind of reduction procedure of processing, production efficiency is improved, hole location is carried out accurate
Positioning, improves the thread pierce punch of product quality, to solve shortcoming in the prior art.
The technical solution adopted in the utility model is: a kind of thread pierce punch, the inside and outside punching being overlapped including central axis
Head, the outer ram be equipped with one end be equipped with limit in convex central through hole, other end bottom end is equipped with along central through hole to evagination
Thread cutting edge out, described inner punch one end are positioning protrusion, and the diameter that positioning protrusion diameter is greater than central through hole is less than limit
The diameter of interior convex, the inner punch, which matches to merge with outer ram central through hole, stretches out thread cutting edge.
Further, plane is machined on the inner punch positioning protrusion.
Further, symmetrically arranged 2 planes of 180 degree are machined on the inner punch positioning protrusion.
Further, the outer ram outer surface is machined with plane.
Further, the interior outer ram is T-shaped.
The utility model compared with prior art, has the advantages that
1, for the utility model by outer ram in being arranged, outer ram is equipped with central through hole of the one end equipped with convex in limiting,
Other end bottom end is equipped with along the outwardly projecting thread cutting edge of central through hole, and described inner punch one end is positioning protrusion, inner punch with
Outer ram central through hole is realized that punching is synchronous with stamping and is carried out, guarantee the verticality of thread with stretching thread cutting edge is merged；It can be with
Tooth hole is accurately positioned, guarantees the precision of product well, improves product quality；Procedure of processing is reduced, production effect is improved
Rate；Time processing forming, saves the time.
2, outer ram is processed as T shape and plane in the utility model, can play the role of it is anti-skidding, take with it is easy to assembly.
Detailed description of the invention
Fig. 1 is the positive structure schematic of the utility model；
Fig. 2 is the overlooking structure diagram of this this utility model；
Fig. 3 is the overlooking structure diagram of inner punch.
In figure, 1. outer rams, 2. inner punches,
11. plane, 12. central through holes, 42. limit interior convex, 14. thread cutting edges
21. positioning protrusion, 211. planes.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of thread pierce punch of the utility model, the outer ram 1 of the T shape including central axis coincidence,
Inner punch 2,1 outer surface of outer ram are machined with plane 11, and the central through hole 12 of convex 13 in limiting, the other end are equipped with equipped with one end
Bottom end is equipped with along the outwardly projecting thread cutting edge 14 of central through hole 12, and 2 one end of inner punch is positioning protrusion 21, is positioned on protrusion 21
Symmetrically arranged 2 planes 211 of 180 degree are machined with, the diameter that positioning 21 diameter of protrusion is greater than central through hole 12 is less than in limit
The diameter of convex 13, inner punch 2, which matches to merge with 1 central through hole 12 of outer ram, stretches out thread cutting edge 14.
In use, thread cutting edge can be simultaneously toward undershoot, to be formed while forming punching for the utility model
First thread mouth of thread reduces after punching the process of tapping again material is thus formed screw thread.
Above embodiment is specific embodiment of the utility model, be not intended to limit the implementation of the utility model with
Interest field, all equivalence changes and modification made according to content described in utility model application scope of patent protection, should all wrap
It includes in present utility model application the scope of the patents.
