Background
At present, laser cutting, or cubic boron nitride ceramic blade grinding cutting, or high-speed steel blade mechanical cutting and other methods are commonly used at home and abroad to process slotted screen pipes, and the slotted structures of the slotted pipes are generally rectangular slots and trapezoidal slots, or combined slots of the rectangular slots and the trapezoidal slots. These seam types all have the defects of large flow resistance of fluid passing through the seam, poor abrasion resistance of the seam, short sand control period, low fluid production efficiency and the like. The streamline slotted sieve tube adopts streamline slots and rectangular slots on two sides of a fluid inflow slot and a fluid outflow slot respectively, and adopts curved-edge trapezoidal slot transition between the streamline slots and the rectangular slots, the cross section structure of the streamline slotted sieve tube is in a composite shape of the streamline slots, the curved-edge trapezoidal slots and the rectangular slots, and the streamline slots not only have the advantages of the existing slotted sieve tube, but also overcome the defects of the existing slotted sieve tube.
It is known that: the existing processing equipment and processing method for the slotted sieve tube can not process the slotted sieve tube with an streamline slotted section.
Disclosure of Invention
In order to overcome the defects of the existing processing method and equipment, the invention aims to provide a composite processing method and equipment of a streamline slit screen pipe.
The specific technical scheme is as follows:
placing the rectangular seam under a streamline rolling tool head, rolling the inside of the seam into a streamline shape by the streamline rolling tool head, and simultaneously extruding the width of the rectangular seam larger than or equal to 0.4mm into the width of the streamline seam larger than or equal to 0.1 mm.
According to the composite processing method of the streamline slit sieve tube, the rectangular slit can be processed on a laser cutting machine firstly, or processed on a numerical control multi-cutter milling machine by using a cubic boron nitride ceramic blade grinding method, or processed on the numerical control multi-cutter milling machine by using a high-speed steel milling cutter processing method, and the rectangular slit sieve tube with the slit width not smaller than 0.4mm is processed firstly.
The equipment consists of a seam scale, streamline double rollers, double rollers with the same diameter, a rolling shaft, a scale resetting mechanism and a rolling shaft frame; the scale resetting mechanism consists of a bracket, a mandril sleeve, a mandril and a spring.
According to the composite processing method and the equipment for the streamline slit sieve tube, the streamline slit is prepared by sequential seam rolling, and a double-rod rolling tool bit with a slit scale or a double-rod rolling tool bit with the same diameter is used for rolling along the length direction of the slit on a numerical control rolling machine tool, so that the inner side of the slit is streamline, and the width of the slit is reduced to the size of the slit scale.

Detailed Description
The invention is further explained below with reference to the drawings and the embodiments.
As shown in fig. 2, a rectangular slit with a slit width of 0.4mm or more is first machined on a laser cutting machine, or a rectangular slit with a slit width of 0.4mm is cut on a pipe by using a ceramic blade or a high-speed steel milling cutter on a numerical control milling and grinding machine.
As shown in the attached figure 1, a streamline seam processing device is arranged on a numerical control rolling machine tool, and the streamline seam processing device comprises (1) a seam scale, (2) a streamline double-rod, (3) a same-diameter double-rod, (4) a rolling shaft, (5) a scale resetting mechanism and (6) a rolling shaft frame; the scale resetting mechanism 5 comprises a support (7), a mandril sleeve (8), a mandril (9) and a spring (10). Before rolling the streamline seam, firstly selecting a seam scale 1 according to the seam width requirement of the streamline seam slotted sieve tube; secondly, selecting and matching a streamline double-stick 2 according to the length and the width of the streamline seam and the wall thickness of the sieve tube; and then, according to the outer diameter of the streamline slit sieve tube, the double sticks 3 with the same diameter are selected and matched. When the streamline seam is rolled, the seam scale 1 is firstly inserted into the rectangular seam, the streamline double-stick 2 is arranged on two sides in the rectangular seam, the double-stick 3 with the same diameter is arranged on two sides outside the seam, the streamline rolling cutter head is applied with force through the rolling shaft 4, and the streamline rolling cutter head is driven to roll along the seam. When the streamline rolling cutter head rolls from one end of the seam to the other end of the seam, the seam end face blocks the movement of the seam scale 1 and blocks the seam scale 1 out of the seam end, and meanwhile, the scale 1 pushes the push rod 9 to compress the spring 10. When the streamline rolling cutter head rolls a seam, the seam scale 1 is inserted into the seam again through the ejector rod 9 under the action of the spring 10, and moves from one end of the seam to the other end of the seam along with the streamline rolling cutter head. Along with the streamline rolling cutter head rolling streamline seams, the seam scale 1 is lifted and inserted repeatedly to limit the width of each seam.
As shown in the attached figure 3, the streamline rolling cutter head rolls the rectangular seam out of a streamline seam finally, the streamline seam formed by combining three sections of seams of the streamline seam at the inlet section, the trapezoid seam at the curved edge of the transition section and the rectangular seam at the outlet section is formed, a flow channel of wide-in, contraction and wide-out is formed, the section shape of the seam conforms to the flow rule of fluid flowing through the seam, the fluid flow resistance is reduced, and the flow capacity of the seam is improved.
Practice proves that the streamline slit slotted screen pipe has the advantages of small flow resistance of flowing through the slit, good permeability of the slit, high utilization rate of the flowing area of the slit, long service life of the screen pipe, easy formation of a stable sand bridge and an effective sand blocking layer at the entrance of the slit and the like besides the advantages of the existing slit screen pipe. Although the streamline slot slotted sieve tube is difficult to process, the slot is formed by rolling, so that the surface strength is high, the application range is wide, and the popularization and the use are convenient.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
