Abstract

The invention relates to oil-water well joint sieve pipe machining equipment and method and particularly relates to a numerical control machining production line and method of a vertical joint sieve pipe. The numerical control machining production line comprises a plurality of sets of main engine assemblies, sleeve clamping assemblies, sleeve supporting assemblies, a sleeve indexing assembly, an axial movement assembly and a base assembly, wherein a cast sliding guide rail is used as the base assembly; the main engine assemblies, the sleeve clamping assemblies and the sleeve supporting assemblies are respectively connected with the base assembly; the sleeve indexing assembly is connected with the base assembly through the sleeve axial movement assembly; and the main engine assemblies drive a saw-tooth milling cutter to rotate to carrying out joint cutting on a sleeve. The numerical control machining production line and method of the vertical joint sieve pipe have the beneficial effects that the sleeve joint cutting is carried out by the numerical control machining production line and method; the cost is low, the operation is simple, the service life of a metal slitting saw is long, the machining efficiency is high and the surface quality of a cutting joint is high, and the size precision and the position precision are high; the sleeves with various parameters and the cutting joints can be machined; furthermore, a vertical joint can be machined by adopting the saw-tooth milling cutter for cutting the joint; the surface quality of the joint is high and the size precision is high; and the adaptability to the size of the sleeve, and the lengths and the gaps of the cutting joints is strong.

Description

technical field [0001] The invention relates to an oil-water well seam screen pipe processing equipment and method, in particular to a vertical seam screen pipe numerical control processing production line and method. Background technique [0002] The slotted screen is a key downhole tool for oilfield exploitation. Its working principle is to process long slots on the oil casing to prevent sand and pass oil. The quality of the slots determines the performance of the screen. At present, there are several methods for the processing of slotted screen pipes. One is the mosaic method, that is, an opening wider than the design size is processed on the part of the casing where the slot is required, and then a metal block slightly narrower than the opening is inlaid and welded firmly. , That is to form a weld, this method is complex to operate, low in efficiency, and the accuracy cannot be guaranteed; one is the laser cutting method, which uses a laser beam to vaporize the mater...

At present, there are several methods for the processing of slotted screen pipes. One is the mosaic method, that is, an opening wider than the design size is processed on the part of the casing where the slot is required, and then a metal block slightly narrower than the opening is inlaid and welded firmly. , That is to form a weld, this method is complex to operate, low in efficiency, and the accuracy cannot be guaranteed; one is the laser cutting method, which uses a laser beam to vaporize the material somewhere in the casing to form a slot, and this method is easy to form a match head , and there is a heat-affected layer on the surface of the seam, and the laser processing equipment is very expensive; one is electric discharge machining, which has low dimensional accuracy of the seam, and the efficiency is not high, and the operation requirements are high; the other is ceramic blade Cutting, this method wears the tool faster, and requires higher manufacturing precision of the processing equipment
