Abstract
The invention discloses a coiled pipe drawing and pulling mold, belonging to the metallic material preparation field. The coiled pipe drawing and pulling mold comprises a first outer mold, a second outer mold and an inner mold, wherein the first outer mold and the second outer mold are coaxially arranged, and the inner diameter of the first outer mold is more than that of the second outer mold; and a plurality of through holes are formed in the first outer mold and the second outer mold. According to the coiled pipe drawing and pulling mold, the plurality of through holes are formed in the first outer mold and the second outer mold, lubricating agents are injected into the mold through the through holes in a coiled pipe drawing and pulling process, therefore, the friction of the mold and the coiled pipe can be reduced, the material deformation can be avoided and the influence on the later use can be avoided, the drawing and pulling efficiency of the mold can be improved, and the service life of the mold is prolonged; and ingates of the first outer mold and the second outer mold are in arc-shaped design, a coiled pipe can enter the mold conveniently, the coiled pipe can be prevented from damage and the drawing and pulling efficiency can be further improved.
Description
Technical field
The present invention relates to one and draw molding tool, be specifically a kind ofly draw molding tool for coil pipe, belong to field of metal preparation.
Background technology
In the production of coil pipe, process, coil pipe blank need repeatedly to draw dial after be wound around, just can complete specification coil pipe being made into expection.Therefore, draw skill of exchanging work particularly important in the processing and manufacturing of coil pipe, in general, draw skill of exchanging work to make the reduction external diameter of coil pipe, internal diameter and tube wall all obtained to a certain extent, the structure of coil pipe improves simultaneously.
The external mold drawing molding tool to generally include to match of coil pipe and an internal mold in prior art, external mold is used for limiting the external diameter of coil pipe, and internal mold is used for limiting the internal diameter of coil pipe.Dial process mistake actual drawing, coordinated by external mold and internal mold and change coil diameter by force, between its coil pipe and mould, frictional force is comparatively large, easily causes material deformation, and group efficiency is drawn in impact.
Summary of the invention
Technical problem to be solved by this invention is to overcome prior art defect, provides a kind of coil pipe and mold friction of effectively reducing to draw the coil pipe dialling efficiency to draw molding tool to improve.
In order to solve the problems of the technologies described above, coil pipe provided by the invention draws molding tool, comprises the first external mold, the second external mold and internal mold, described first external mold and the second external mold arranged in co-axial alignment, and the internal diameter of described first external mold is greater than the internal diameter of the second external mold; Described first external mold and the second external mold are equipped with some through holes.
The present invention is by arranging multiple through hole at the first external mold and the second external mold simultaneously, draw in the process of dialling at coil pipe and inject lubricant by some through holes to mould inside, reduce mould and coil pipe friction, thus avoid material deformation, affect follow-up use, want to promote drawing of mould simultaneously and dial efficiency, extend the mold use life-span.
By the curved setting of progressive die mouth of the first external mold, the second external mold, can the entering of convenient coil pipe, avoid coil pipe injured, improve further to draw and dial efficiency.
The 1.15-1.25 internal diameter of the first external mold being set to the internal diameter of the second external mold doubly, draws and dials better quality, efficiency is higher.
Accompanying drawing explanation
Fig. 1 is that coil pipe of the present invention draws molding lamps structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, coil pipe of the present invention draws molding tool, comprises external mold 1, internal mold 2 and front tube reducing external mold 3, external mold 1 and front tube reducing external mold 3 arranged in co-axial alignment, and front tube reducing external mold 3 is positioned at the front of external mold 1, and the internal diameter of front tube reducing external mold 3 is 1.15-1.25 times of the internal diameter of external mold 1.
The progressive die mouth of external mold 1 and front tube reducing external mold 3 is curved, can the entering of convenient coil pipe 4.
Several through holes 5 communicated with mould inside that external mold 1 and front tube reducing external mold 3 all leave; can to external mold 1 and front tube reducing external mold 3 injection lubricant by name by through hole 5; to reduce coil pipe 4 and the frictional force between external mold 1 and front tube reducing external mold 3, protect body better, improve to draw and dial efficiency.
The course of work of the present invention is: coil pipe 4 is introduced into front tube reducing external mold 3, carry out tube reducing by injecting lubricant in through hole 5 forward tube reducing external mold 3 to reduce friction simultaneously, coil pipe 4 after tube reducing enters external mold 1 and internal mold 2 again, simultaneously by injecting lubricant to reduce friction in through hole 5 forward external mold 1, under coordinate of external mold 1 with internal mold 2, realizing coil pipe 4 be out of shape.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be considered as protection scope of the present invention.
