Abstract
The invention discloses a gas squeezing tool for a step gas screen tube. The gas squeezing tool adopts the following types: a groove gas squeezing knife, a double-blade furrow gas squeezing knife and a circular wheel extrusion knife. One side of the groove gap squeezing knife is a flat blade while the other side is an inclined blade, and a groove is squeezed along the gap; the double-blade furrow gas squeezing knife has two blades with two bumps riding on two sides of the gap with the squeezed groove, a furrow is extruded, and thereby bulges are formed nearby; the circular wheel of the circular wheel extrusion knife is installed in the knife handle to rotate, and used for pressing the furrow and the bulges, and thereby a step gap with narrow outer side and wide inner side is formed.
Description
Art
The present invention relates to a kind of step slit screen pipes caulking cutter, belong to field of machining.
Background technology
General oilfield slotted screen pipes section seam shape is divided into rectangular slits and trapezoidal seam.Rectangular slits screen casing easily blocks, and oil recovery efficiency is low; Trapezoidal slit screen pipes resistance to gravel erosive wear ability, easily causes out-seam size to broaden.And the wide step sewer of the narrow inseam of out-seam is for the advantage of rectangular slits and trapezoidal seam two kinds seam shape structure, overcome its shortcoming, section structure is in " outer narrow rectangle → transition trapezoidal → inner width rectangle " compound shape.
But adopt traditional cutter cannot process section step slit screen pipes.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the adopted technical scheme that solves the problem is to provide a kind of step slit screen pipes caulking cutter.
It is characterized in that: it takes following pattern;
A. groove caulking cutter;
B. twolip ditch dug with a plow caulking cutter;
C. circle wheel extruding cutter.
Above-mentioned step slit screen pipes caulking cutter, described groove caulking cutter, side is flat sword, and side is oblique sword, will squeeze out groove along seam.
Above-mentioned step slit screen pipes caulking cutter, described twolip ditch dug with a plow caulking cutter, has two blades being with biconvex, rides over the both sides of the seam extruding groove, squeeze out " ditch dug with a plow ", neighbouring formation " protuberance ".
Above-mentioned step slit screen pipes caulking cutter, described circle wheel extruding cutter, circle wheel is arranged in handle of a knife and rotates, and " ditch dug with a plow " and " protuberance " is flattened, and forms the step seam of outer narrow inner width.
Accompanying drawing explanation
Accompanying drawing 1 is groove caulking cutter figure of the present invention, 1. handle of a knifes in figure, 2. groove cutter, 3. alignment pin.
Accompanying drawing 2 is twolip ditch dug with a plow caulking cutter figure.
Accompanying drawing 3 is circle wheel extruding cutter figure, 1. circle wheels in figure, 2. alignment pin, 3. handle of a knife.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
From accompanying drawing 1, groove caulking cutter, side is flat sword, and side is oblique sword, will squeeze out groove along seam.In process, oblique sword will aim at the medial surface of the rectangular slits cut out.
From accompanying drawing 2, twolip ditch dug with a plow caulking cutter, has two blades being with biconvex, rides over the both sides of the seam extruding groove, squeeze out " ditch dug with a plow ", neighbouring formation " protuberance ".The trend of extruding tries hard to allow the groove that squeezed out vertical.
From accompanying drawing 3, round wheel extrudes cutter, and circle wheel is arranged in handle of a knife and rotates, and " ditch dug with a plow " and " protuberance " is flattened, and groove is vertical, contraction, the step seam of the outer narrow inner width of formation.
Claims (4)
1. a step slit screen pipes caulking cutter, is characterized in that: it takes following pattern;
A. groove caulking cutter;
B. twolip ditch dug with a plow caulking cutter;
C. circle wheel extruding cutter.
2., according to claim 1 said step slit screen pipes caulking cutter, described groove caulking cutter, side is flat sword, and side is oblique sword, will squeeze out groove along seam.
3., according to claim 1 said step slit screen pipes caulking cutter, described twolip ditch dug with a plow caulking cutter, has two blades being with biconvex, rides over the both sides of the seam extruding groove, squeeze out " ditch dug with a plow ", neighbouring formation " protuberance ".
4., according to claim 1 said step slit screen pipes caulking cutter, described circle wheel extruding cutter, circle wheel is arranged in handle of a knife and rotates, and " ditch dug with a plow " and " protuberance " is flattened, and forms the step seam of outer narrow inner width.
