Opening-closing-type profile drawing mould

Abstract

The invention discloses an opening-closing-type profile drawing mould. The opening-closing-type profile drawing mould comprises a mould sleeve which consists of an upper mould sleeve and a lower mouldsleeve which are both semi-circular and are matched with each other; a mould core is arranged in the mould sleeve; the mould core consists of an upper mould core and a lower mould core which are bothsemi-circular and are matched with each other; the upper mould core is arranged in the upper mould sleeve; the lower mould core is arranged in the lower mould sleeve; a diameter-variable passage is formed in the center of the mould core; a left upper mould groove and a right upper mould groove are separately formed in the two ends of an inner side surface opening of the upper mould sleeve; a leftlower mould groove and a right lower mould groove are separately formed in the two ends of an inner side surface opening of the lower mould sleeve; and a left upper mould core groove and a right upper mould core groove are separately formed in the two ends of an outer side surface opening of the upper mould core. According to the opening-closing-type profile drawing mould, a detachable opening-closing-type structure is adopted, a machining section of pulling can be flexibly selected; and besides, operation of a pulling procedure can be finished in one step, and repeated reciprocated operationis avoided.

Description

technical field [0001] The invention relates to a variable-diameter drawing equipment for producing copper tube profiles, in particular to an open-close type profile drawing die, which belongs to the technical field of copper tube processing. Background technique [0002] With the application of high-precision copper tubes in various fields more and more widely, the market's demand for tubes is not limited to traditional copper coil tube materials, and more and more demands are also directed to profiles, especially for variable diameter tubes. Demand is increasing day by day. At present, when enterprises are producing variable-diameter pipes, because they require different pipe diameters and shapes on the same profile, they need to use special processes and molds to produce them. Most of the existing production molds are integrated structures. This kind of mold can usually only start the drawing and deformation operation from the end of the copper pipe, but if it is necessa...
