Abstract
The invention provides a process for connecting a pipeline piece shell with a branch pipe, which comprises the steps of: firstly drawing a pre-perforated hole on the shell out of a cylindrical surface step by using a special drawing and forming device, cutting to form a neat opening, and then welding with an end port of the branch pipe. The welded seam is a planar circumferential welded seam and can be finished by using an automatic welding manner. According to the process, the production efficiency can be greatly improved, the welded seam is even, and the bent position of a pipeline piece is smooth and fluent, so that the quality of the product is ensured. The pipeline piece or a pressure container device made by the process is especially suitable for occasions with high pressure and corrosive mediums.
Description
Technical field
The present invention relates to a kind of pipeline member cylindrical shell and be connected technology, belong to pressure pipeline spare processing method with arm.
Background technology
As pressure pipeline spare, perhaps pressure container apparatus, in use cylindrical shell needs to be connected with arm and communicates, and existing connected mode normally cuts out the intersection otch in the line of pipeline member cylindrical shell corresponding site earlier, again the arm link is processed into respective shapes after employing manual welding mode be welded.This mode has very big defective in manufacture process, by manual line, intersection is irregular space curve to the accuracy of intersection entirely, be difficult to carry out the automation welding, can only adopt the manual welding mode, not only production efficiency is low, and labour intensity is big, and weldquality is difficult to guarantee, the welding position is rough inhomogeneous, and withstand voltage poor corrosion resistance is when pipeline internal medium has corrosivity, pressure is higher, or then can not adapt to when having more high-tech require to inner-walls of duct.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, provide a kind of and can enhance productivity and welding quality, guarantee that the pipeline member cylindrical shell of product serviceability is connected technology with arm.
The objective of the invention is to reach like this: the pipeline member cylindrical shell is connected technology with arm and is meant following steps: (1) makes a special-purpose drawing and forming device, comprises special-purpose die, dedicated male die and hydraulic jack; (2) cut out pre-hole earlier at pipeline member cylindrical shell link position; (3) the pipeline member cylindrical shell is placed on the arc surface of special-purpose die horizontal direction in the special-purpose drawing and forming device circumferential, the axial location of calibration cylindrical shell; Dedicated male die is sent into from body end surface, corresponding with the endoporus of special-purpose die vertical direction; The hydraulic cylinder piston rod liter that is placed in special-purpose die lower end is opened, pierce into the punch centre bore, the end face nut screwing clamping; Start oil hydraulic cylinder and drive punch decline, to the stretched face of cylinder of cylinder lateral wall step; (4) with neat mouthful of the face of cylinder step cutting behind the drawing and forming, be welded in same planar circumferential with a pipe port.
Above-mentioned special-purpose die horizontal direction arc surface is consistent with pipeline member cylindrical shell external diameter, and the vertical direction diameter of bore is consistent with an external diameter of pipe of connection.Dedicated male die comprises the conical surface and the face of cylinder, and the thick and conventional drawing process of the material gap of pipeline member is depended in the gap of the punch face of cylinder and die endoporus, and cylindrical shell behind the drawing and forming and arm welding can adopt automatic welding manner to finish.
Adopt above technology, pipeline member cylindrical shell perforate drawing and forming, end Qi Kou, be connected and in same planar circumferential, finish with arm with automatic welding manner, enhance productivity greatly,, and can guarantee even weld even adopt manual welding also much easier, the smooth smoothness of pipeline member bent port part, and then guarantee product quality.Pipeline member or the pressure container apparatus made by this technology are particularly useful for the pressure height, the mordant occasion of medium.
Description of drawings
Fig. 1 is the simplified and arm connection diagram of pipeline member;
Fig. 2 is a cylindrical shell connecting portion drawing and forming schematic diagram.
The specific embodiment
Desire barrel dliameter be the pipeline member of Φ a to connect caliber on simplified be the arm of Φ b, cut out pre-hole at simplified 1 connecting portion earlier, be of a size of X, X is than the little 10～30mm of Φ b, special-purpose die 2 horizontal directions have
Circular arc camber, vertical direction has the endoporus of Φ b, cylindrical shell 1 is lain in a horizontal plane on the circular arc camber of die 2, die 2 is installed in the top of hollow bearing 6, the circumferential datum line of cylindrical shell 1 aligns with the datum line on the die, the axial location line of pre-drilled cavity aligns with the vertical datum line of die 2, and this vertical datum line is by the die inner hole centreline and perpendicular to the plane of die circular arc camber center line and the intersection of die external cylindrical surface and end face.Dedicated male die 3 one ends are taper seat, and an end is that diameter is the face of cylinder of Φ c, Φ c=Φ b-E1-E2, and E1 is simplified wall thickness, E2 is drawing process gap (above dimensional units is mm); Punch 3 usefulness forklifts are pushed into simplified pulling eye position from cylindrical shell one end, corresponding with die 2 centers, open the hydraulic jack 4 that is installed in the die below, piston rod 7 is passed the punch centre bore, tighten with nut 5; Hydraulic cylinder is returned fall, drive punch and move downward, finish cylindrical shell perforate drawing and forming.With neat mouthful of the face of cylinder step burr cutting after the moulding,, can adopt automatic soldering method to finish the welding of planar circumferential weld seam 9 continuously at last with arm 8 end face spot welding assembling.
