Abstract
A non-damage pipe bending round mould is provided with an assembling positioning boss (1), an assembling positioning groove (2), fan-shaped platforms (3) and an assembling positioning hole (6). A U-shaped base body (4) is formed between the two fan-shaped platforms (3). A U-shaped forming groove (5) is installed in the middle of the U-shaped base body (4). An arc of the cross section of the U-shaped forming groove (5) is composed of a bottom arc (a) and two end arcs (b). The two end arcs are two arcs of the same circle and are positioned in a bilateral symmetry mode. The diameter of the bottom arc (a) is matched with the diameter of a to-be-bent round pipe. The diameters of the end arcs (b) are longer than the diameter of the bottom arc (a). The bottom arc (a) intersects with the end arcs (b) on a half position of the section height of the U-shaped forming groove (5), and arc intersection parts are rounded off . When a pipe bending mould assembled by the non-damage pipe bending round mould is used to process and form round pipes of various bending shapes, the extrusion force of two ends of the U-shaped forming groove of the round mould to the round pipes during a pipe bending process of the round pipes can be remarkably reduced, the phenomenon of surface scratching can be avoided, and the quality of a bent pipe product can be ensured.
Description
Technical field
The utility model belongs to pipe crimping tool, is specifically related to a kind of accessory of bend pipe mould.
Background technology
Refrigerant tubing in the air conditioning for automobiles will use a kind of bend pipe mould Come machine-shaping usually, and bend pipe circle mould is the core part of used bend pipe mould.The bend pipe circle mould of existing structure, wherein the cross sectional shape of U-shaped forming tank is semicircle, with its assembling bend pipe mould in the bend pipe process, owing to can producing distortion when the bending, pipe becomes ellipse, pipe after the distortion at its oval long axis direction namely in the horizontal direction in forming tank cross section, can be subject to the extruding of forming tank end arc outer rim, thus in the bend pipe process to the tube surface injury, can not guarantee the quality of machine-shaping bend pipe product.
Summary of the invention
For the defects that existing structure bend pipe circle mould exists, intend it is carried out architecture advances, design a kind of not damaged bend pipe circle mould, to guarantee the quality of machine-shaping bend pipe product.
Technical solution adopted in the utility model is as follows.
A kind of not damaged bend pipe circle mould, be provided with assembling and positioning boss, assembling and positioning groove, fan-shaped platform and assembling and positioning hole, form U-shaped matrix between Two the fan-shaped platform, offer U-shaped forming tank at U-shaped matrix middle part, it is characterized in that: the cross section circular arc of U-shaped forming tank is comprised of arc at the bottom of a section and two sections end arcs; The end arc is two sections arcs of same circle, and left-right symmetry; The diameter of end arc and the diameter of pipe to be curved are complementary, and the diameter of end arc is greater than the diameter of end arc; End arc and end arc intersect at half position of U-shaped forming tank depth of section, circular arc intersection rounding off.
Justify the pipe that mould is the various camber shapes of bend pipe mould machine-shaping of core part assembling in order to the utility model bend pipe, can significantly reduce the U-shaped forming tank of round mould two ends in the extruding force of pipe bend pipe process to pipe, make pipe stressed evenly, eliminate the surface tear phenomenon, can guarantee the quality of machine-shaping bend pipe product fully.
Description of drawings
Fig. 1 is the utility model bend pipe circle mould cross-sectional plane structural representation;
Fig. 2 is that the A of Fig. 1 is to the view plane structural representation;
Fig. 3 is the local planar structure schematic diagram that amplifies of the U-shaped forming tank of the utility model bend pipe circle mould.
In the drawings, 1-assembling and positioning boss, 2-assembling and positioning groove, the 3-fan-shaped platform, the 4-U mold base, 5-U type forming tank, 6-assembling and positioning hole, arc at the bottom of the a-, b-holds arc.
The specific embodiment
Further specify the concrete structure of the utility model bend pipe circle mould below in conjunction with accompanying drawing.
A kind of not damaged bend pipe circle mould, be provided with assembling and positioning boss 1, assembling and positioning groove 2, fan-shaped platform 3 and assembling and positioning hole 6, form U-shaped matrix 4 between Two the fan-shaped platform 3, offer U-shaped forming tank 5 at U-shaped matrix 4 middle parts, it is characterized in that: the cross section circular arc of U-shaped forming tank 5 is comprised of arc a at the bottom of a section and two sections end arc b; The end arc is two sections arcs of same circle, and left-right symmetry; The diameter of end arc a and the diameter of pipe to be curved are complementary, and the diameter of end arc b is greater than the diameter of end arc a; End arc a and end arc b intersect at half position of U-shaped forming tank 5 depth of sections, circular arc intersection rounding off.
