Abstract
The invention discloses a kind of step slit screen pipes combined machining method, belong to field of machining, the processing for solving step slit screen pipes.Its technical scheme is：Sintex can be first used, or uses HSS sawblade milling cutter, cut out the rectangular slits wide of width >=1.0mm；With the squeezing knife tool of the double gradients of band, extruded along the length direction of seam, make to be extruded into opposite groove on the inside of seam；With the crowded knife with biconvex, the both sides of the seam of extruded groove are ridden over, squeeze out " ditch dug with a plow ", be formed about protuberance；Finally roll, " ditch dug with a plow " is flattened, form the step seam of outer narrow inner width.
Description
Art
The present invention relates to a kind of step slit screen pipes combined machining method, belong to field of machining.
Background technology
General oilfield slotted screen pipes section slit is divided into rectangular slits and trapezoidal seam.Rectangle slit screen pipes are susceptible to block, and adopt
Oily efficiency is low；The resistance to gravel erosive wear ability of trapezoidal slit screen pipes, easily causes out-seam size and broadens.And the narrow inseam of out-seam is wide
Step sewer overcomes its shortcoming for two kinds of advantages of slit structure of rectangular slits and trapezoidal seam, and section structure is in " narrow rectangle → mistake outward
Cross trapezoidal → inner width rectangle " compound shape.
But section step slit screen pipes cannot be processed using traditional machining tool and traditional processing method.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the used technical scheme that solves the above problems is to provide a kind of step
Slit screen pipes combined machining method.
It is characterized in that：It takes following steps;
A. rectangular slits wide are first cut out；
B. groove is squeezed out along seam；
C. " ditch dug with a plow " is extruded in the both sides of seam；
D. step seam is finally rolled out.
Above-mentioned step slit screen pipes combined machining method, it is described first to cut out rectangular slits wide, can be used on numerical-control milling and grinding lathe
Sintex, or HSS sawblade milling cutter is used on numerical control multitool milling machine, cut out the rectangular slits wide of width >=1.0mm.
Above-mentioned step slit screen pipes combined machining method, it is described to squeeze out groove along seam, on numerical control caulking machine, with the double slopes of band
The squeezing knife tool of degree, extrudes along the length direction of seam, makes to be extruded into opposite groove on the inside of seam.
" ditch dug with a plow " is extruded in above-mentioned step slit screen pipes combined machining method, the both sides in seam, still on numerical control caulking machine,
With the crowded knife with biconvex, the both sides of the seam of extruded groove are ridden over, squeeze out " ditch dug with a plow ", be formed about protuberance.
Above-mentioned step slit screen pipes combined machining method, the last step that rolls out is stitched, on roller press, by " ditch dug with a plow " pressure
It is flat, form the step seam of outer narrow inner width.
Brief description of the drawings
Accompanying drawing 1 is the screen casing figure for first cutting out rectangular slits wide of the invention；
Accompanying drawing 2 is to squeeze out groove figure along the seam of screen casing；
Accompanying drawing 3 is the both sides for riding over seam, squeezes out the figure of " ditch dug with a plow "；
Accompanying drawing 4 is, by rolling, to flatten " ditch dug with a plow " and protuberance, forms step seam.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the present invention is further described.
From accompanying drawing 1, rectangular slits wide are first cut out, sintex can be used on numerical-control milling and grinding lathe, or it is many in numerical control
HSS sawblade milling cutter is used on knife milling machine, the rectangular slits wide of width >=1.0mm are cut out.
From accompanying drawing 2, groove is squeezed out along seam, on numerical control caulking machine, with the squeezing knife tool of the double gradients of band, along seam
Length direction extruding, make to be extruded into opposite groove on the inside of seam.
From accompanying drawing 3, " ditch dug with a plow " is extruded in the both sides of seam, still on numerical control caulking machine, with the crowded knife with biconvex, ridden
In the both sides of the seam of extruded groove, " ditch dug with a plow " is squeezed out, be formed about protuberance.
From accompanying drawing 4, step seam is finally rolled out, on roller press, " ditch dug with a plow " is flattened, form the platform of outer narrow inner width
Rank is stitched.
