Abstract
The invention discloses a kind of processing technologys of complicated abnormal shape pipe, it successively includes straight shaping round tube, length interception, the molding of taper pipe portion, the molding of trumpet flare end and the molding of square tube portion, stainless-steel sheet is shaped to straight round tube by welded tube mill, then the straight round tube of length needed for needing to intercept further according to production, it first passes through machine for shrinking and taper pipe portion is gone out to straight round tube one end progress necking machine-shaping of interception, expanding is carried out in the tubing other end of molded taper pipe portion out by pipe expanding device again and molds trumpet flare end, one end molds taper pipe portion, the other end, which molds the cylindrical parts in the middle part of the straight tube at trumpet flare end and passes through pressure side's machine again and carry out the side's of pressure working process, molds square tube portion, final molding goes out complicated abnormal shape pipe, it is square tube for forming middle part, both ends are respectively the complicated abnormal shape of conical pipe and trumpet flare Pipe has the characteristics that shaping efficiency height, the complicated abnormal shape pipe good integrity, the structural strength that mold are high.
Description
Technical field
The present invention relates to stainless steel pipe material molding technology fields, and in particular to a kind of processing work of complicated abnormal shape pipe
Skill.
Background technique
It includes taper pipe portion 1, square tube portion 2 and trumpet flare end 3 to complicated abnormal shape pipe as shown in Fig. 1, traditional
The mode for forming the complicated abnormal shape pipe is passed through again after being separately formed above-mentioned taper pipe portion 1, square tube portion 2 and trumpet flare end 3
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 separately formed seamless welding again and link together, not only molding effect
Rate is low, and the complicated abnormal shape pipe structural strength molded is inadequate.
Summary of the invention
In view of the deficiencies of the prior art, the present invention is intended to provide a kind of be respectively for molding middle part as square tube, both ends
The processing technology of the complicated abnormal shape pipe of conical pipe and trumpet flare.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of processing technology of complicated abnormal shape pipe, comprising the following steps:
A, straight shaping round tube, by stainless-steel sheet, by welded tube mill, machine-shaping is straight circular tube shaped as required；
B, length intercepts, and the straight round tube that step a is molded needs to cut out required length by production；
C, taper pipe portion forms, and is carried out at necking by the one end of machine for shrinking to the straight round tube of institute's intercepted length in step b
Reason molds taper pipe portion；
D, trumpet flare end forms, and the straight tube by pipe expanding device taper pipe portion out molded to one end in step c is another
One end carries out expanding and molds trumpet flare end；
E, square tube portion forms, and one end in step d molded taper pipe portion, the other end out are molded trumpet flare end
Cylindrical parts in the middle part of straight tube carry out the side's of pressure working process by pressure side's machine and mold square tube portion.
The invention has the following beneficial effects:
A kind of processing technology of complicated abnormal shape pipe of the present invention, being used to form middle part as square tube, both ends is respectively conical pipe
With the complicated abnormal shape pipe of trumpet flare, complicated abnormal shape pipe good integrity, structural strength high with shaping efficiency, mold are high
The characteristics of.

In figure: 1, taper pipe portion；2, square tube portion；3, trumpet flare end.
Specific embodiment
With reference to the accompanying drawing and specific embodiment, the invention will be further described, in order to be more clearly understood that this
Invent claimed technical idea.
A kind of processing technology of complicated abnormal shape pipe of the present invention as shown in Figure 2,3, comprising the following steps:
A, straight shaping round tube, by stainless-steel sheet, by welded tube mill, machine-shaping is straight circular tube shaped as required；
B, length intercepts, and the straight round tube that step a is molded needs to cut out required length by production；
C, taper pipe portion forms, and is carried out at necking by the one end of machine for shrinking to the straight round tube of institute's intercepted length in step b
Reason molds taper pipe portion 1；
D, trumpet flare end forms, and the straight tube by pipe expanding device taper pipe portion 1 out molded to one end in step c is another
One end carries out expanding and molds trumpet flare end 3；
E, square tube portion forms, and one end in step d molded taper pipe portion 1, the other end out are molded 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.
Stainless-steel sheet is shaped to straight round tube by welded tube mill by processing technology of the present invention, is then needed further according to production
The straight round tube of length needed for intercepting first passes through machine for shrinking and goes out taper pipe portion to straight round tube one end progress necking machine-shaping of interception
1, then expanding is carried out in the tubing other end of molded taper pipe portion 1 out by pipe expanding device and molds trumpet flare end
3, the cylindrical parts that one end molds taper pipe portion 1, the other end molds in the middle part of the straight tube at trumpet flare end 3 pass 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 Fig. 1, used in forming
Portion is square tube, both ends are respectively the complicated abnormal shape pipe of conical pipe and trumpet flare, has the complexity that shaping efficiency is high, molds
The high feature of shape tube good integrity, structural strength.
For those skilled in the art, it can make other each according to the above description of the technical scheme and ideas
Kind is corresponding to be changed and deforms, and all these change and deform the protection model that all should belong to the claims in the present invention
Within enclosing.
