Abstract
The invention discloses a machining method and machining equipment of an angle of an outer bevel of an application programming interface (API) casing thread. The machining equipment consists of stripping and rough turning tool holders (1 and 2), a facing and burring tool holder (3) and a finish turning tool holder (4), wherein the stripping and rough turning tool holders (1 and 2) are provided with stripping and outer beveling tools (5 and 7) and rough turning tools (6 and 8); the facing and burring tool holder (3) is provided with a facing and inner beveling tool (9) and a burring tool (10); and the finish turning tool holder (4) is provided with a finish turning tool (11). The machining equipment is characterized in that: the mounting angle of the burring tool (10) on the facing and burring tool holder (3) is alpha which is more than 25 DEG and less than or equal to 30 DEG. The machining method comprises the following steps of: primary outer beveling, stripping/thread rough turning, flattening/inner beveling, thread finish turning and burring/finial beveling. Only the mounting angle of the burring tool is changed, and an unqualified bevel angle of the outer beveling tool is corrected by the burring tool, so that a great amount of waste of spare parts is reduced, and cost is saved.
Description
Technical field:
The present invention relates to the seamless steel pipe production technical field, is the processing method and the process equipment of the outer chamfer angle of a kind of API casing threads specifically.
Background technology:
At present, in petroleum casing pipe was produced, the processing of body screw thread was very crucial together operation.The technological process of body screw thread processing is: once accomplish outer chamfering-stripping famine/rough threading (adorn two cuttves on handle of a knife and carry out work simultaneously same)-planar end surface/interior chamfering (same two sword faces cutter carry out work simultaneously)-finish turning screw thread-deburring.In the above-mentioned technological process; The main effect of machining screw is the connection when being convenient to sleeve pipe and on the oil field, using; Wherein the main effect of outer chamfering is when thread connection, to be easy to butt joint; The main effect of deburring is to remove the burr that outer chamfering and screw initial thread are buckled, in order to avoid burr scratches screw thread, influence stubborn the connecing of screw thread and cause thread gluing etc.; The setting angle of burr cutter is 25 °.
Gas thread standard A PI 5B changed plate in 2008; Before plate change; API 5B carries out the 14th edition (1996) standard; The outer chamfer angle of regulation is
in the standard; Plate change back API 5B carries out the 15th edition (2008) standard, and the outer chamfer angle of regulation is 60 ° ± 5 ° in the standard.Therefrom can find out; The lower limit of the 14th edition outer chamfer angle of standard just in time is the upper limit of the outer chamfer angle of the 15th edition standard; Like this, there is the possibility that meets the demands in the outer chamfering tool that adopts the 14th edition standard design in theory when processing the product of carrying out by the 15th edition standard; There are fluctuation and deviation will cause the outer chamfer angle of machining screw to surpass 65 ° in the actual production slightly, do not meet standard-required.
Usually; Outer chamfering is that the chamfering blades of and outer rose reamer waste by stripping is accomplished; Deburring is accomplished by burring knife; In order to satisfy the chamfering requirement of API 5B the 15th edition, need cutter waste by the 14th edition stripping that manufactures and designs of API 5B and rough turn handle of a knife, face work and deburring handle of a knife and compositions such as stripping famine and outer rose reamer is manufactured and designed again, so just caused a large amount of wastes by the 14th edition handle of a knife that manufactures and designs of API 5B and cutter head spare part.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art, the processing method of the outer chamfer angle of a kind of API casing threads is provided.
Another object of the present invention provides the process equipment of the outer chamfer angle processing method of a kind of API of realization casing threads.
The present invention mainly solves the existing waste that changes the spare part of the existing equipment that brings owing to standard.
In order to achieve the above object, the present invention is achieved in that the processing method of the outer chamfer angle of a kind of API casing threads, and its special character is that it comprises following processing step:
The preliminary outer chamfering of a, stripping famine and rough threading, stripping waste and outer rose reamer and roughing tool completion by stripping on the waste and rough turn handle of a knife are worked into 65 ° with outer chamfer angle;
B accomplishes planar end surface and interior chamfering, is accomplished by face work on face work and the deburring handle of a knife and interior rose reamer;
C accomplishes the finish turning screw thread, is accomplished by the finishing tool on the finish turning handle of a knife;
D accomplishes deburring and final chamfering, accomplishes deburring and final chamfering by the burring knife on face work and the deburring handle of a knife, makes outer routine angle be worked into a certain angle between 60 °-65 °, promptly meets the requirement of 60 ° ± 5 ° of new standards.
Realize the process equipment of the outer chamfer angle processing method of API casing threads; It by last stripping waste and rough turn handle of a knife, waste and rough turn handle of a knife, face work and deburring handle of a knife of stripping and finish turning handle of a knife are formed down; Stripping waste and outer rose reamer and following roughing tool are installed down on following stripping famine and the rough turn handle of a knife; Stripping waste and outer rose reamer and last roughing tool are installed on last stripping famine and the rough turn handle of a knife, face work and interior rose reamer and burring knife are installed on face work and the deburring handle of a knife, on the finish turning handle of a knife finishing tool is installed; Its special character is that the setting angle of the burring knife on described face work and the deburring handle of a knife is α, chooses 25 °＜α≤30 °.
The choosing of α angle among the present invention: 25 °＜α≤30 °; Utilize the waste and preliminary outer chamfering to 65 of outer rose reamer of stripping °, utilize again the final outer chamfering of burring knife arrive (90 °-α), as shown in Figure 7, scheme chamfering length L=6mm at home and abroad, then burring knife processing capacity maximum Δ is:
Δ＝(tgα-tg25°)×L。
Through calculating, if utilize the final outer chamfering to 60 of deburring ° (be α=30 °), then burring knife processing capacity maximum Δ is 0.67mm, can cause the processing capacity of burring knife bigger, and blade consumption is big, and may cause the end face shoulder; Select 25 °＜α≤30 °, like α=27 °, burring knife processing capacity maximum Δ is 0.26mm, and this moment, outer chamfer angle was 63 °, met the 15th edition standard-required of API 5B, and in theory to the consuming cost influence of burr cutter not quite.
Compared with present technology the processing method and the process equipment of the outer chamfer angle of a kind of API casing threads of the present invention have outstanding substantive distinguishing features and marked improvement; Other handle of a knife is not changed; Only through face work and deburring handle of a knife are carried out minor modifications; Promptly change the setting angle of burring knife, utilize burring knife to revise and accomplish the underproof chamfer angle of outer rose reamer, thus the problem that solution can not be satisfied the 15th edition standard-required of API 5B by the handle of a knife and the cutter head of the 14th edition standard design manufacturing of API5B; Reduce a large amount of wastes of spare part, practiced thrift cost.
