Abstract
A cutter of a steel pipe inner wall is simple in structure, good in using effect, and capable of effectively eliminating scratches on the steel pipe inner wall. The cutter is connected to one end, facing towards a clamp, of a core rod, and comprises a cutter seat, a cutter head and a cover plate. An accommodating groove is formed in the end face of the end, facing towards the clamp, of the core rod, and a penetrating hole parallel to the axis of the core rod is formed in the bottom of the accommodating groove. The cutter seat comprises a seat body in a circular truncated cone shape and a cylindrical connection body, and the seat body is integrated with the connection body. A through hole is formed in the wall of the accommodating groove, and a pressure spring is arranged between the end face, facing towards the bottom of the accommodating groove, of the cover plate and the cutter head. The cutter can be used in the steel pipe cold-drawing technology, and after a steel pipe is subjected to cold drawing, the cutter head can be pushed out when the connection body is screwed in the tail end of the core rod; then a rotation motor is started, the core rod is slowly pulled out at constant speed to achieve cutting and grinding of the inner wall of the steel pipe, scratches on the inner wall of the steel pipe are effectively eliminated, machining efficiency of the steel pipe in subsequent production is substantially improved, meanwhile, work cost is greatly saved, and work efficiency is improved.
Description
Technical field
The utility model relates to seamless steel pipe and manufactures field, relates in particular to the improvement of the cutting tool of steel pipe inner wall.
Background technology
In traditional cold drawing steel tube technique, the one end of clamping steel pipe by clamp, then steel pipe and plug are pulled out from the ground of external mold, more therefrom extract plug out; Like this, its external diameter of the steel pipe after subtracting wall tube reducing is consistent with the internal diameter external diameter consistent and its internal diameter and plug of external mold.Yet, it is found that, because plug is servo-actuated the pulling out of frictional force of dependence and steel pipe inner wall, therefore, will on the inwall of steel pipe, cause inevitable wearing and tearing cut, thus the great inconvenience of bringing to follow-up processing.
Utility model content
The utility model is for above problem, provide a kind of simple in structure, result of use good, can effectively eliminate the cutting tool of the steel pipe inner wall of cut on steel pipe inner wall.
The technical solution of the utility model is: be connected to plug towards one end of clamp, described cutting tool comprises tool rest, cutter head and cover plate, described plug offers storage tank on the end face of one end of clamp, and the bottom land of described storage tank offers the through hole with the axis parallel of described plug;
Described tool rest comprises round table-like pedestal and the cylindrical connector that be being connected as a single entity, described connector be located in through hole and and described through hole between be threaded connection; Described pedestal is contained in storage tank, and the axle center of described pedestal and the axis parallel of described plug and pedestal are greater than the pedestal area of the end face of the bottom land of storage tank dorsad towards the area of the end face of the bottom land of storage tank;
On the cell wall of described storage tank, offer through hole, described cutter head is contained in described through hole;
The dismountable notch that is connected to described storage tank of described cover plate, described cover plate is provided with stage clip between the end face of the bottom land of storage tank and described cutter head.
One end that the connector of described tool rest stretches out described through hole is socketed with a fastening bolt and a spline bolt.
Described plug is provided with electric rotating machine away from one end of clamp, by described electric rotating machine, drives described Mandrel Rotating.
The utility model can be used in cold drawing steel tube technique, at steel pipe, completes after cold-drawn, from the tail end screw-in connector of plug, releases cutter head; Opening electric rotating machine, and slowly at the uniform velocity pull out plug, thereby realize the cutting polishing to the inwall of steel pipe, effectively eliminated the cut on the inwall of steel pipe, significantly improved the working (machining) efficiency of steel pipe subsequent production.This case incorporates the polishing of the inwall of steel pipe in the cold-drawing technology of steel pipe, has significantly saved job costs, has improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is use view of the present utility model;
In figure, 1 is plug, the 10th, and storage tank, the 2nd, tool rest, the 21st, pedestal, the 22nd, connector, the 23rd, fastening bolt, the 24th, spline bolt, the 3rd, cutter head, the 4th, cover plate, the 5th, stage clip.
The specific embodiment
The utility model as shown in Figure 1-2, be connected to plug 1 towards one end of clamp (being the head end of plug 1), described cutting tool comprises tool rest 2, cutter head 3 and cover plate 4, described plug 1 offers storage tank 10 on the end face of one end of clamp, and the bottom land of described storage tank 10 offers the through hole with the axis parallel of described plug 1;
Described tool rest 2 comprises round table-like pedestal 21 and the cylindrical connector 22 that be being connected as a single entity, described connector 22 be located in through hole and and described through hole between be threaded connection; Described pedestal 21 is contained in storage tank 10, and the axis parallel of the axle center of described pedestal 21 and described plug 1 and pedestal 21 are greater than pedestal 21 area of the end face of the bottom land of storage tank 10 dorsad towards the area of the end face of the bottom land of storage tank 10;
On the cell wall of described storage tank 10, offer through hole, described cutter head 2 is contained in described through hole; Like this, from the tail end screw-in connector of plug, can from through hole, release cutter head, thus the inwall of cutting polishing steel pipe.
The dismountable notch that is connected to described storage tank 10 of described cover plate 4, described cover plate 4 is provided with stage clip 5 between the end face of the bottom land of storage tank 10 and described cutter head 3.Cutter head is remained towards one end of tool rest on the side that is fitted in tool rest, while effectively avoiding plug in stretching into steel pipe, the unexpected inwall that scratches steel pipe; Also can, when the inwall of steel pipe being cut to polishing, play the effect of cutter head strong fix.
One end that the connector 22 of described tool rest 2 stretches out described through hole is socketed with a fastening bolt 23 and a spline bolt 24.Avoid when the inwall of steel pipe being cut to polishing, tool rest produces servo-actuated.
Described plug is provided with electric rotating machine away from one end (being the tail end of plug) of clamp, by described electric rotating machine, drives described Mandrel Rotating.
