Abstract
The utility model belongs to a processing of a metal tube, in particular to an edge processing of a metal tube. The utility model comprises a die body, and the utility model is characterized in that a die body forming end is a step-like structure formed by a processed surface vertical to a die body axis and an oxygonial surface inclining downward composed with the die body axis by a rounding off anastomosis. The utility model solves the problem that the mechanical processing edge folding angle of a smoke pipe flanged edge is small, due to the flanged edge of the smoke pipe edge being processed through a machine, the smoke pipe edge is regular and beautiful, and simultaneously, the demand of the design can be met.
Description
Technical field
The utility model belongs to the processing of metal tube, specifically is a kind of edge treated of metal tube.
Background technology
The smoke pipe flange is the syndeton of smoke pipe and tube sheet in the high temperature drum of boiler, the flange of tradition smoke pipe is to utilize bearing flange tube expander more, but utilize bearing flange tube expander to come flange, the angle of its flange only can reach with the smoke pipe axial line and be about 15～20 °, can't reach the requirement of 90 ° of flange of smoke pipe, must finish 90 ° flange by artificial or other special equipment again, not only working (machining) efficiency is low, and is difficult to satisfy the every requirement in the design drawing.
Summary of the invention
90 ° of flanging dies of a kind of smoke pipe, comprise mold, it is characterized in that the mold forming ends be by the face of being processed perpendicular to the mold axial line and with face rounding off that the mold axial line the constitutes acute angle formed step-like structure that joins to lower tilt.
Described mold forming ends is slick and sly cambered surface transition between the face of lower tilt and mold.
In the smoke pipe turn-up process, not only realized 90 ° of flange of mechanization after utilizing this mould, and the flange moulding is regular, can satisfy the every requirement in the design drawing, the use of this mould does not simultaneously need configure dedicated equipment, adopts the general pneumatic spanner of prior art to get final product.
Description of drawings
Fig. 1: the utility model embodiment master TV structure schematic diagram.
The A-A cutaway view of Fig. 2: Fig. 1.
The vertical view of Fig. 3: Fig. 1.
The specific embodiment
After the edge of smoke pipe being processed as 15～20 ° by conventional apparatus, again will be as Fig. 1, mold 1 shown in 3 is installed on the pneumatic spanner of prior art, the bottom surface 4 of mold 1 is linked closely with the smoke pipe edge, start behind the pneumatic spanner with the rotation of mold 1 along the smoke pipe edge, be 15～20 ° of smoke pipe edges of slightly turning up and just proceeded the flange action along the rounding off face 3 on the mold 1, and always along face 2 flange perpendicular to axial line, be directly processed to set angle, mold 1 forming ends is slick and sly cambered surface transition 5 between the face of lower tilt and mold, the forming surface of mold 1 can be rotated along the smoke pipe edge smoothly, this mould has not only solved the little problem of smoke pipe flange machining flange angle, and because of the flange of smoke pipe be to form by machining, so the smoke pipe edge is regular, attractive in appearance, the while can be satisfied the needs of design.
Claims (2)
1,90 ° of flanging dies of a kind of smoke pipe, comprise mold, it is characterized in that the mold forming ends be by the face of being processed perpendicular to the mold axial line and with face rounding off that the mold axial line the constitutes acute angle formed step-like structure that joins to lower tilt.
2,90 ° of flanging dies of smoke pipe according to claim 1 is characterized in that the mold forming ends is slick and sly cambered surface transition between the face of lower tilt and mold.
