Abstract
The utility model discloses a mould for removing an inner welding rib of a welding steel pipe. The utility model is characterized in that the utility model not only comprises a sizing zone 3, a lightening zone 4, a no-touch deformation zone 6, and a connecting screw end hole 7 for connecting an inner mould and a core rod, but also comprises a groove 5, a cutting edge 1 and a clearance hole 2. As the mould is adopted, the procedure of mechanical processing for removing the inner welding rib of the welding pipe can be omitted, and a welding pipe billet with the inner welding reinforced steel can be directly drawn to the required specification.
Description
A kind of mould of removing weldering muscle in the welded still pipe, the utility model are specially adapted to welded still pipe and remove interior weldering muscle.
As everyone knows, accurate welded still pipe pipe just can carry out drawing after the interior weldering muscle in the welded tube must being removed before being drawn into production tube, and before the utility model, the removal of weldering muscle all adopts mechanical means to carry out in the welded tube.Therefore below 30 millimeters, interior weldering muscle just is difficult to remove at φ for small-bore welded tube, particularly internal diameter, even more than 30 millimeters, removal effect is also unsatisfactory, in addition at φ for caliber, shortcomings such as the employing mechanical means is removed the interior weldering muscle of welded tube, also can cause labour intensity big, and productivity ratio is low.
The purpose of this utility model is exactly to develop the mould that a kind of big small-bore welded tube all can effectively be removed interior weldering muscle, and makes the removal of welded tube weldering muscle in drawing just can be carried out simultaneously, thereby has got rid of the operation of welding muscle in the mechanical removal.
Measure of the present utility model is to open a groove on the internal mold that the welded tube drawing procedure is adopted, the groove end is processed into knife-edge, when the welded tube drawing, need only the interior weldering muscle that the groove end is processed into the groove alignment welded tube of knife-edge, just can in the welded tube drawing, the interior weldering muscle of welded tube be got rid of.
Now in conjunction with the accompanying drawings the utility model is illustrated.
Fig. 1 is a front view of the present utility model, and 1 is cutting edge among the figure, and 2 is chip-removal hole, and 3 is sizing area, and 4 is diameter reducing area, and 5 is groove, and 6 are juxtaposition metamorphose district not, and 7 is the connecting screw stomidium, and Fig. 2 is the utility model side view, and Fig. 3 is the utility model vertical view.
The inner mold that general drawing steel tube place uses has included sizing area 3, and diameter reducing area 4 and juxtaposition metamorphose district 6 not have one can make internal mold be fixed on screw connection stomidium 7 on the plug in the end in juxtaposition metamorphose district 6 not.Therefore the effect of this internal mold only makes skelp when drawing, owing to tube wall gradually attenuate reach certain internal diameter size, when opening a groove 5 on one's body at this internal mold mould, and after groove groove end is processed into knife-edge, so as long as when the welded tube drawing, with interior weldering muscle alignment indentation, will in the skelp drawing, under the effect of blade 1, the interior weldering muscle of welded tube be got rid of, for the weldering muscle bits of getting rid of are successfully discharged, also has a chip removal mouth 2 in the end of cutting edge 1.
Of the present utility model being characterised in that, except including sizing area 3, diameter reducing area 4, juxtaposition metamorphose district 6 connects outside the connecting screw stomidium 7 of internal mold and plug, also includes groove 5, cutting edge 1 and chip-removal hole 2,
Adopt this inner mold just can omit the interior weldering muscle operation that machining is removed welded tube, the skelp of weldering muscle pulls to needed specification in directly will having, thereby work efficiency is improved greatly, use through the our factory, respond well, adopt the utility model to the welded tube advantageous particularly of processing specification less than 30 millimeters of φ.
