Abstract
The utility model discloses a split stamping cutter. The split stamping cutter comprises a cutter body, wherein the cutter body comprises two long cutters and two short cutters which are distributed in parallel along the circumference evenly at intervals, and the adjacent sides of the long cutters and short cutters are in contact. The split stamping cutter has the following advantages: 1) the cutter body can be easily taken out of the small hole end of a drill stem; the cutter body is of a split structure and is provided with two long cutters and two short cutters, thus after the cutter body stamps a bulge (inner flash) and separates, the widest part of the cross section of each of the separated long cutters or short cutters is far less than the diameter of the integrated cutter body, the separated cutter body can be taken out of the small hole end of the inner hole of the drill stem and the time and labor can be saved; and 2) the use cost can be reduced; the long cutters and short cutters of the cutter body are distributed at intervals; when the split stamping cutter is in use, the long cutters first work, after the long cutters stamp the bulge (inner flash), the short cutters begin to work; and the used material has enough toughness, thus the service life of the cutter body can be effectively prolonged.
Description
Technical field
The utility model relates to the stamping knife technical field, especially relates to a kind of split stamping knife.
Background technology
When processing drilling rod, need to remove the convexity (dividing the limit promptly) that drill pipe bore produces through the mode of friction welding (FW).General, remove the protruding mode that is adopted and remove for using stamping knife.Wherein, used stamping knife has the cutter hub of one.Because the outlet of the small bore end of drill pipe bore is often less than the cutter hub diameter, cutter hub only can take out from big nose end mostly, wastes time and energy.And, because cutter hub is taked high-speed steel, costing an arm and a leg, its damage causes processing cost high.Therefore be necessary to improve.
The utility model content
To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of split stamping knife, and it is low that it has use cost, and cutter hub is easy to from the characteristics of drilling rod small bore end taking-up.
The technical scheme that the utility model adopted is: the split stamping knife, comprise cutter hub, said cutter hub comprises rimmer knife and short sword, rimmer knife and short sword respectively are 2, and be parallel to each other spaced apart uniformly along circumference, simultaneously, the adjacent side of rimmer knife and short sword contacts.
The utility model has the advantages that: 1, cutter hub is easy to take out from the drilling rod small bore end.Cutter hub is taked split-type structural, has the structure of 2 rimmer knifes and short sword.Like this, when cutter hub dashed protruding (interior overlap) separately after, cross section the widest part of rimmer knife that separates or short sword is far smaller than the diameter of the cutter hub of one.Thereby the cutter hub that separates can take out from the small bore end of drill pipe bore, and is time saving and energy saving.2, use cost reduces.Cutter hub is taked long and short cutter mode spaced apart.During work, rimmer knife carries out work earlier, and after rimmer knife thrust convexity (interior overlap), short sword side started working, and uses material that enough toughness is arranged, and has effectively prolonged the service life of cutter hub.

Fig. 1 is the main sectional structure sketch map of the utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
A kind of split stamping knife comprises cutter hub.Cutter hub comprises rimmer knife 1 and short sword 2.Rimmer knife 1 respectively is 2 with short sword 2, and be parallel to each other spaced apart uniformly along circumference, simultaneously, rimmer knife 1 contacts with the adjacent side of short sword 2.That is: when rimmer knife 1 and short sword 2 respectively were 2, rimmer knife 1 all had orthogonal two sides with short sword 2.Obviously, the bottom of rimmer knife 1 and short sword 2 should be on the same horizontal plane.
Need to prove, when washing out convexity, can take earlier the part of convexity to be gone out the breach of two symmetries, will remain the mode that two valvulas wash out again.Like this, the convexity of washing out can be taken out from the endoporus small bore end of drilling rod equally.
