Description
Technical field
The present invention relates to a kind of step slit screen pipes by using plastic processing method and equipment, belong to screen casing processing technique field.
Background technology
Cutting seam sieve tube is petroleum drilling and mining instrument and equipment, for completion or oil extraction sand prevention in advance.Cutting seam sieve tube superior performance and cheap, is subject to domestic and international oil field user's welcome.
The traditional section seam type of cutting seam sieve tube is divided into rectangular slits, trapezoidal seam etc.Cross-Section Rectangular seam is that the inside and outside wall gap of pipe is equally wide, and the tube wall strength after processing is high.But oil is being mingled with fine sand easily to be stopped up from time in the inflow pipe of gap, and oil recovery efficiency is low, stop up when serious and can cause the accidents such as well of collapsing.
Trapezoidal seam section is narrow and wide at interior wall opening at tube outer wall opening, and shape is isosceles trapezoid.Trapezoidal sewer has stronger " self-cleaning " effect, and gravel enters behind seam chamber, is easy to be washed away by fluid, is difficult for forming sand plug.The inside and outside pressure drop of pipe is little, and oil recovery efficiency is high, and sand controlling result is good.But outer seam surface is subject to quicksand abrasion, and gap broadens, and affects filter sand effect.
New seam type-section step seam: be narrow slit section near pipe outer wall, retained the high advantage of section rectangular slits tube wall strength, can improve the ability of resistance to gravel erosive wear.And be wide seam section near inside pipe wall, retain that section is trapezoidal is sewed with " filtering self-cleaning " advantage.
But adopt traditional processing method, as CBN grinding wheel mill seam, high-speed steel milling cutter milling seam, laser lancing etc., be difficult to process section step seam, particularly out-seam width is the seam that 0.1mm is even narrower.
summary of the invention
In order to overcome the deficiency of above-mentioned existing conventional method and equipment, the invention provides a kind of section step seam plastic processing method and a kind of caulking machine with caulking function.
The technical scheme addressing the above problem is:
A kind of section step seam processing method, concrete steps are as follows:
A. first use universal cutter, as CBN emery wheel, high-speed steel cutter blade or laser beam, with processed pipe fitting radial alignment, cutting out thousands of width along body axis direction is 1mm, even wider rectangular slits;
B. then on the caulking machine with caulking function, with special squeezing knife tool, squeeze out along the rectangular slits both sides of having cut the ditch dug with a plow that is parallel to rectangular slits.Because this cutter has certain geometry and angle, so can produce plastic deformation a certain amount of, that original rectangle sealing is narrowed along the metal of rectangular slits both sides, reach body section and be the step-like of outer narrow inner width.
Above-mentioned step slit screen pipes by using processing method and equipment, the described caulking machine with caulking function, formed by lathe bed, idle wheel, servo-actuated chuck, feed cylinder, pressure head oil cylinder, squeezing knife tool, pressure head trailer, trailer carrier, support roller, active chuck, chain, drive unit, trailer carrier is arranged on lathe bed, dragged by chain and idle wheel by drive unit along lathe bed, and pressure head trailer is contained in trailer carrier inside, synchronizes and advance with trailer carrier.
Above-mentioned step slit screen pipes by using processing method and equipment, in described pressure head trailer, pressure head oil cylinder and feed cylinder are housed, in the time that running to precalculated position, trailer carrier locks, pressure head hydraulic oil cylinder driving is contained in six or more squeezing knife tools tooled joint simultaneously on pressure head trailer, along with squeezing knife tool is dark to the pressure of surface of the work, feed cylinder also promotes pressure head trailer and moves axially along workpiece.
Above-mentioned step slit screen pipes by using processing method and equipment, after the extruding work of the complete seam in a row of described squeezing knife tool, be arranged on active chuck and the servo-actuated chuck holding workpiece circular index at two ends on lathe bed, squeezing knife tool continues the extruding of next row seam, until complete all extruding of seam of complete cycle, be contained in the support roller supporting workpiece on lathe bed.
The invention has the beneficial effects as follows, can process expeditiously section step slit screen pipes by using.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Accompanying drawing the 1, the 2nd, section step seam plastic processing method of the present invention.
Accompanying drawing 3 is caulking machine structural representations with caulking function of the present invention.
Detailed description of the invention
Fig. 1 is with special squeezing knife tool aligning use commonsense method, as used CBN emery wheel, high-speed steel cutter blade or laser beam, cutting out thousands of width along pipe fitting axis direction is 1mm, even wider rectangular slits, under pressure head hydraulic oil cylinder driving, the rectangular slits both sides of cutting are applied to extruding force, under the driving of feed cylinder, advance along body axis direction, squeeze out the ditch dug with a plow that is parallel to rectangular slits simultaneously.Because this special cutter has certain geometry and angle, so can produce plastic deformation a certain amount of, that original rectangle sealing is narrowed along the metal of rectangular slits both sides, reach body section be as shown in Figure 2, out-seam is narrow and that inseam is wide is step-like.
1. lathe beds in Fig. 3,2. idle wheel, 3. servo-actuated chuck, 4. feed cylinder, 5. pressure head oil cylinder, 6. squeezing knife tool, 7. pressure head trailer, 8. trailer carrier, 9. support roller, 10. active chuck, 11. chains, 12. drive units
In accompanying drawing 3, the described caulking machine with caulking function, formed by lathe bed, idle wheel, servo-actuated chuck, feed cylinder, pressure head oil cylinder, squeezing knife tool, pressure head trailer, trailer carrier, support roller, active chuck, chain, drive unit, trailer carrier is arranged on lathe bed, dragged by chain and idle wheel by drive unit along lathe bed, and pressure head trailer is contained in trailer carrier inside, synchronizes and advance with trailer carrier.
Above-mentioned step slit screen pipes by using processing method and equipment, in described pressure head trailer, pressure head oil cylinder and feed cylinder are housed, after running to the initiating terminal that precalculated position is caulking, trailer carrier locks with lathe bed, pressure head hydraulic oil cylinder driving is contained in six or more squeezing knife tools tooled joint simultaneously on pressure head trailer, because special cutter has certain geometry and angle, metal in the certain width of sealing both sides is tilted to sealing centre position simultaneously, plastic deformation occurs.Along with squeezing knife tool is dark to the pressure of surface of the work, feed cylinder also promotes pressure head trailer and moves axially along workpiece.Through so several times process, can make the seam cross section before processing be extruded into the wide step seam seam cross section of the narrow inseam of out-seam.
Above-mentioned step slit screen pipes by using processing method and equipment, after the extruding work of the complete seam in a row of described squeezing knife tool, the active chuck and the servo-actuated chuck that are arranged on two ends on lathe bed accommodate workpiece circular index, squeezing knife tool continues the extruding of next row seam, until complete all extruding of seam of complete cycle, be contained in the support roller support tubes on lathe bed.
Compare with traditional machining tool and processing method, the present invention has the following advantages:
Can process expeditiously, the out-seam width that conventional method cannot be processed be 0.1mm even narrower, performance is better than the step seam of rectangular slits and trapezoidal seam.
