Abstract
The invention discloses a kind of processing technology of complicated abnormal shape pipe,It includes straight shaping round tube successively,Length is intercepted,Taper pipe portion is molded,The step such as the shaping of trumpet flare end and the shaping of square tube portion,Stainless-steel sheet is shaped to straight pipe by welded tube mill,Then the straight pipe of length needed for interception is needed further according to production,First pass through machine for shrinking carries out necking machine-shaping and goes out taper pipe portion to the straight pipe one end for intercepting,Again by pipe expanding device it is molded go out taper pipe portion the tubing other end carry out expanding and mold trumpet flare end,One end molds taper pipe portion,The cylindrical parts that the other end is molded in the middle part of the straight tube at trumpet flare end carry out the side's of pressure working process and mold square tube portion by pressure side's machine again,Final molding goes out complicated abnormal shape pipe,It is square tube for being molded middle part,Two ends are respectively the complicated abnormal shape pipe of conical pipe and trumpet flare,It is high with shaping efficiency,The complicated abnormal shape pipe good integrity for molding,The characteristics of structural strength is high.
Description
Technical field
The present invention relates to stainless steel pipe material molding technology field, and in particular to a kind of processing work of complicated abnormal shape pipe
Skill.
Background technology
It includes taper pipe portion 1, square tube portion 2 and trumpet flare end 3 to complicated abnormal shape pipe as shown in Figure 1, traditional
Being molded the mode of the complicated abnormal shape pipe is, passes through again after above-mentioned taper pipe portion 1, square tube portion 2 and trumpet flare end 3 are molded respectively
The combination that links together of taper pipe portion 1, square tube portion 2 and trumpet flare end 3 is formed complicated abnormal shape pipe by the mode of seamless welding；
But above-mentioned taper pipe portion 1, square tube portion 2 and trumpet flare end 3 are molded again seamless welding and link together respectively, not only shaping is imitated
Rate is low, and the complicated abnormal shape tubular construction insufficient strength for molding.
The content of the invention
In view of the shortcomings of the prior art, the present invention is intended to provide a kind of for molding middle part for square tube, two ends are respectively
The processing technology of the complicated abnormal shape pipe of conical pipe and trumpet flare.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of processing technology of complicated abnormal shape pipe, comprises the following steps：
A, straight shaping round tube, by stainless-steel sheet, by welded tube mill, machine-shaping is straight circular tube shaped on request；
B, length interception, the straight pipe that step a is molded cut out required length by production needs；
C, the shaping of taper pipe portion, are carried out at necking by machine for shrinking to one end of the straight pipe of institute's intercepted length in step b
Reason molds taper pipe portion；
D, trumpet flare end shaping, by pipe expanding device it is molded to one end in step c go out taper pipe portion straight tube it is another
One end carries out expanding and molds trumpet flare end；
E, the shaping of square tube portion, by one end in step d it is molded go out taper pipe portion, the other end mold trumpet flare end
Cylindrical parts in the middle part of straight tube carry out the side's of pressure working process and mold square tube portion by pressure side's machine.
The present invention has the advantages that：
A kind of processing technology of complicated abnormal shape pipe of the present invention, it is used to be molded middle part for square tube, two ends respectively conical pipe
With the complicated abnormal shape pipe of trumpet flare, the complicated abnormal shape pipe good integrity that molds high with shaping efficiency, structural strength are high
The characteristics of.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the invention will be further described, in order to be more clearly understood that this
The claimed technological thought of invention.
A kind of processing technology of complicated abnormal shape pipe of the invention, comprises the following steps as shown in Figure 2,3：
A, straight shaping round tube, by stainless-steel sheet, by welded tube mill, machine-shaping is straight circular tube shaped on request；
B, length interception, the straight pipe that step a is molded cut out required length by production needs；
C, the shaping of taper pipe portion, are carried out at necking by machine for shrinking to one end of the straight pipe of institute's intercepted length in step b
Reason molds taper pipe portion 1；
D, trumpet flare end shaping, by pipe expanding device it is molded to one end in step c go out taper pipe portion 1 straight tube it is another
One end carries out expanding and molds trumpet flare end 3；
E, square tube portion shaping, by one end in step d it is molded go out the taper pipe portion 1, other end mold trumpet flare end 3
Straight tube in the middle part of cylindrical parts the side's of pressure working process carried out by pressure side's machine mold square tube portion 2.
Processing technology of the present invention, straight pipe is shaped to by welded tube mill by stainless-steel sheet, is then needed further according to production
The straight pipe of length needed for interception, first pass through machine for shrinking carries out necking machine-shaping and goes out taper pipe portion to the straight pipe one end for intercepting
1, then by pipe expanding device it is molded go out taper pipe portion 1 the tubing other end carry out expanding and mold trumpet flare end
3, one end molds the taper pipe portion 1, other end and molds cylindrical parts in the middle part of the straight tube at trumpet flare end 3 and passes through pressure side again
Machine carries out the side's of pressure working process and molds square tube portion 2, and final molding goes out complicated abnormal shape pipe as shown in Figure 1, in shaping
Portion is the complicated abnormal shape pipe that square tube, two ends are respectively conical pipe and trumpet flare, the complexity that molds high with shaping efficiency
Shape tube good integrity, the characteristics of structural strength is high.
For a person skilled in the art, technical scheme that can be as described above and design, make other each
Plant corresponding change and deform, and all these changes and deforms the protection model that should all belong to the claims in the present invention
Within enclosing.
