Abstract
A kind of pass structure rolling rectangular section titanium or titanium alloy profile leader pass, the pass is for above and below, symmetrical hexagon pass, and the upper and lower side of the hexagon pass is to pass central protuberance and symmetrically arc-shaped.The present invention overcomes the defect of the prior art, meets strict demand of the special user to finished form and size.
Description
Technical field
The invention belongs to titanium or titanium alloy shape extrusion technical fields, and in particular to a kind of rolling rectangular section titanium and titanium close
The pass structure of metal type material leader pass.
Background technique
The pass structure that titanium or titanium alloy profile leader pass in rectangular section is rolled in prior art is hexagon pass, should
Hexagon green shape after groove rolling may be molded to rectangular section titanium and titanium conjunction by the rolling of rectangle last groove
Metal type material.Have a disadvantage in that the left and right two sides of the rectangle finished section bar of the groove rolling bulges, and longitudinal four seamed edges are
Arc chord angle does not meet strict demand of the special user to finished form and size.
Summary of the invention
The present invention provides a kind of pass structure for rolling rectangular section titanium or titanium alloy profile leader pass, overcomes existing
The defect of technology meets strict demand of the special user to finished form and size.
The technical scheme adopted by the invention is that：A kind of pass rolling rectangular section titanium or titanium alloy profile leader pass
Structure, the pass is for above and below, symmetrical hexagon pass, and the upper and lower side of the hexagon pass is into pass
Cardiac prominence rises and symmetrically arc-shaped.
The arc-shaped camber A is 0.1~1mm.
The width L of the hexagon pass is bigger, and the value of camber A is bigger, and the height H of the hexagon pass is bigger,
The value of camber A is smaller.
Compared to the prior art, the left and right two sides for the rectangle finished section bar that the present invention rolls is smooth, does not bulge, and vertical
It is rectangular to four seamed edges, meet strict demand of the special user to finished form and size.And the utilization rate height of raw material,
High in machining efficiency, the consistency of trimmed size size is good, and production cost is low.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is rectangular section titanium or titanium alloy profile last groove schematic diagram.
Specific embodiment
With reference to the accompanying drawing 1,2 and specific embodiment the present invention is described in detail.
A kind of pass structure rolling rectangular section titanium or titanium alloy profile leader pass, the pass is for above and below, left and right
Symmetrical hexagon pass, and the upper and lower side of the hexagon pass is to pass central protuberance and symmetrically arc-shaped
1, i.e., the center of circle of the circular arc is in the outside of pass.
Described arc-shaped 1 camber A is 0.1~1mm.The width L of the hexagon pass is bigger, and the value of camber A is got over
Greatly, the height H of the hexagon pass is bigger, and the value of camber A is smaller.
The present invention by by the trench bottom (the upper and lower side of hexagon pass) of hexagon pass to pass central protuberance, shape
Arc-shaped the 1 of grooving bottom protrusion, the hexagon green shape upper and lower surface after rolling is inwardly recessed, left and right two sides convex
Out.When the green shape, which is rotated by 90 °, to be rolled into rectangular section titanium or titanium alloy profile last groove, mainly pass through
The upper and lower surface outwardly protruded is squeezed, so that left and right two is faced out extension and realizes molding.Since left and right two sides is inwardly recessed, left and right two
Face out extension and filled and led up existing female parts just, and the seamed edge of existing longitudinal direction four substantially will not deformation occurs,
Therefore the left and right two sides of the rectangle finished section bar of rolling is smooth, does not bulge, and longitudinal four seamed edges are rectangular, meet spy
Different strict demand of the user to finished form and size.And the utilization rate of raw material is high, high in machining efficiency, trimmed size size
Consistency is good, and production cost is low.
Above-described embodiment, only presently preferred embodiments of the present invention, the practical range being not intended to limit the invention, thus it is all with
The equivalent variations that content described in the claims in the present invention is done should all be included within scope of the invention as claimed.
