Abstract
Drawing wound form small-bend radius bent pipe mould.When bend pipe mould design in the past, bend pipe R/D being less than to 1.5 does not have suitable method, and when pipe bends, ovality and shaping being difficult to meet drawing requirement, and easily produces wrinkling, triangle, the curved quality problems such as flat.Composition of the present utility model comprises: be fixed on the sector disk (1) on bed piece by keyway, described sector disk has asymmetric bend pipe mould groove (2), described asymmetric bend pipe mould hole has the straight pipeline part tilted to the inside, described sector disk and fixing fixture block (3) are connected by screw, described fixing fixture block is fixedly connected with chute (4), the side of described chute has the limiting groove (5) that cross section is arc, and described limiting groove and described asymmetric bend pipe mould groove stick together and form bend pipe mould hole.The utility model is small radius bending on the industry pipe same planes such as boiler, building, furniture.
Description
technical field:
the utility model relates to a kind of drawing wound form small-bend radius bent pipe mould, be the mould of 1.1 for R/D (relative bending radius) can be bent, the drawing wound form small-bend radius bent pipe mould of various pipe small radius bending at grade can be realized, the industries such as boiler, building, furniture can be widely used in.
background technology:
when bend pipe mould design in the past, bend pipe R/D being less than to 1.5 does not have suitable method, and when pipe bends, ovality and shaping being difficult to meet drawing requirement, and easily produces wrinkling, triangle, the curved quality problems such as flat.
utility model content:
the purpose of this utility model is to provide a kind of drawing wound form small-bend radius bent pipe mould.
above-mentioned object is realized by following technical scheme:
a kind of drawing wound form small-bend radius bent pipe mould, its composition comprises: be fixed on the sector disk on bed piece by keyway, described sector disk has asymmetric bend pipe mould groove, described asymmetric bend pipe mould hole has the straight pipeline part tilted to the inside, described sector disk and fixing fixture block are connected by screw, described fixing fixture block is fixedly connected with chute, the side of described chute has the limiting groove that cross section is arc, and described limiting groove and described asymmetric bend pipe mould groove stick together and form bend pipe mould hole.
beneficial effect:
1. the utility model adopts special Blanking cavity design, thus reach extraordinary bending tube forming, when boiler industry uses, the product less for relative bending radius significantly can improve actual internal area, thus reduction circulating resistance, realize deisgn product performance better.For relative bending radius about 1.1 time, curved rear pipe ovality reaches the mould of more than 92%.Sector disk adopts suitable type groove, after inside tube bending springback, reach profile attractive in appearance.Chute adopts anti-deformation type groove, and allow outside pipe and first produce predeformation, after resilience, pipe recovers original profile substantially.Sector disk and art chute designs not at pipe center line matched moulds, but adopt suitably eccentric, avoid maximum distortion place matched moulds, thus complete perfect profile.
use the method for this drawing wound form small-bend radius bent pipe mould as described below: pipe is fixed on fixing fixture block by chuck, time bending, chute and sector disk provide reversible deformation power, reach very perfectly circularity when allowing workpiece produce flexural deformation, the relative bending radius of pipe can be low to moderate 1.088.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is top views of accompanying drawing 1.
accompanying drawing 3 is sector disk of the present utility model structural representations when being arranged on lathe.
accompanying drawing 4 is right views of accompanying drawing 3.
accompanying drawing 5 is top views of accompanying drawing 3.
accompanying drawing 6 is that the A-A of accompanying drawing 3 is to sectional view.
accompanying drawing 7 is structural representations of chute of the present utility model.
accompanying drawing 8 is side views of accompanying drawing 7.
detailed description of the invention:
embodiment 1:
a kind of drawing wound form small-bend radius bent pipe mould, its composition comprises: be fixed on the sector disk 1 on bed piece by keyway, described sector disk has asymmetric bend pipe mould groove 2, described asymmetric bend pipe mould hole has the straight pipeline part tilted to the inside, described sector disk and fixing fixture block 3 are connected by screw, described fixing fixture block is fixedly connected with chute 4, the side of described chute has the limiting groove 5 that cross section is arc, and described limiting groove and described asymmetric bend pipe mould groove stick together and form bend pipe mould hole.Described fixing fixture block has the groove 6 of fixing pipe to be curved.
