Abstract
The utility model discloses a kind of Split punchs for drill pipe thickening, it includes the formed punch ontology and punch holder of split settings, wherein, central mounting hole is provided at the center of the punch holder, the tail end of the formed punch ontology is provided with convex shoulder, corresponding convex shoulder is provided with stepped hole in the tail end of the central mounting hole, and the head end of the formed punch ontology passes through the central mounting hole and limited by convex shoulder and stepped hole.The above-mentioned Split punch for drill pipe thickening adopts a split structure, and in upsetting process, formed punch ontology bears main impact force, and when formed punch ontology fractures or damages, formed punch ontology need to only be taken off to the formed punch ontology more renewed from punch holder.It is not only simple in structure, it is easy to accomplish；And be conveniently replaceable, reduce the cost of drill pipe thickening.
Description
Technical field
The utility model belongs to drill pipe thickening technology, more particularly, to a kind of Split punch for drill pipe thickening.
Background technique
In order to improve the bonding strength of drilling rod ontology and connector, drilling rod needs to carry out thickening process, currently, drill pipe thickening is set
Standby to generally comprise thickening mould and formed punch, drilling rod is set in thickening mould, carries out jumping-up by formed punch.Formed punch is in upsetting process
It is middle to need to bear very big impact force, it easily snaps off or damages, but the existing formed punch for drill pipe thickening is all integral type
Structure needs replacing entire formed punch once fractureing or damaging, will definitely increase the processing cost of drilling rod in this way.
Utility model content
The purpose of this utility model is to provide a kind of Split punchs for drill pipe thickening, to solve in the prior art
Integral type formed punch for drill pipe thickening there are problems that increasing drilling rod processing cost.
For this purpose, the utility model uses following technical scheme:
A kind of Split punch for drill pipe thickening comprising the formed punch ontology and punch holder of split settings, wherein institute
State and be provided with central mounting hole at the center of punch holder, the tail end of the formed punch ontology is provided with convex shoulder, corresponding convex shoulder in
The tail end of the central mounting hole is provided with stepped hole, and the head end of the formed punch ontology passes through the central mounting hole and by convex
Shoulder and stepped hole are limited.
Particularly, the formed punch ontology successively includes convex shoulder, the first cylindrical section and the second cylindrical section from tail end to head end,
The radius of first cylindrical section is greater than the radius of the second cylindrical section, and described in the radius of first arc section and length cooperation
The internal diameter and length of central mounting hole are arranged.
Particularly, the tail end of the punch holder is provided with the external thread section for being installed on punch holder on extrusion equipment.
Particularly, several planar slots for being convenient for punch holder installation are offered on the middle part outer wall of the punch holder.
The beneficial effects of the utility model are that the Split punch for drill pipe thickening uses compared with prior art
Split type structure, in upsetting process, formed punch ontology bears main impact force, when formed punch ontology fractures or damages, only needs
Formed punch ontology is taken off to the formed punch ontology more renewed from punch holder.It is not only simple in structure, it is easy to accomplish；And it is convenient for
Replacement, reduces the cost of drill pipe thickening.

State the purpose of specific embodiment, it is not intended that in limitation the utility model.Term " and or " used herein includes one
Or any and all combinations of multiple relevant listed items.
Shown in please referring to Fig.1 to Fig.3, in the present embodiment, a kind of Split punch for drill pipe thickening is set including fission
The formed punch ontology 1 and punch holder 2 set, are provided with central mounting hole 3 at the center of the punch holder 2, and the formed punch ontology 1 is from tail
Hold head end successively and include convex shoulder 4, the first cylindrical section 5 and the second cylindrical section 6, the radius of first cylindrical section 5 is greater than the
The radius of two cylindrical sections 6, and the radius of first arc section 5 and length cooperate the internal diameter and length of the central mounting hole 3
Setting, corresponding convex shoulder 4 are provided with stepped hole 7 in the tail end of the central mounting hole 3, and the head end of formed punch ontology 1 passes through described
Central mounting hole 3 is simultaneously limited by the cooperation of convex shoulder 4 and stepped hole 7.
The tail end of punch holder 2 is provided with the external thread section 8 for being installed on punch holder 2 on extrusion equipment, while formed punch
Several planar slots 9 for being convenient for punch holder 2 to install are offered on the middle part outer wall of seat 2.
Above-mentioned Split punch only need to unload punch holder 2 after the damage of formed punch ontology 1 from extrusion equipment, will be new
Formed punch ontology 1 penetrates punch holder 2, then punch holder 2 is loaded onto extrusion equipment.
Note that above are only the preferred embodiment and institute's application technology principle of the utility model.Those skilled in the art's meeting
