[0002] High-temperature alloy irregularly shaped sleeve parts are widely used in oil and gas drilling due to their ability to operate for extended periods at temperatures above 600℃ and under certain stress. They possess high high-temperature strength, good oxidation and corrosion resistance, and excellent fatigue and fracture toughness. However, the inherent difficulty in machining high-temperature alloys and their irregular internal cavity structure lead to long machining times and high tool consumption, thus increasing the processing cost of these parts.

[0006] Preferably, in the processing technology of the high-temperature alloy irregular sleeve-type parts, in step S4, there are three through holes with a diameter of ф10-12mm, a width of 6-8mm and a length of 30-32mm for the inclined groove, and a width of 10-12mm and a length of 40-42mm for the positioning groove. The three through holes and the positioning groove are evenly arranged at equal intervals around the center of the first stage on the end face of the first stage.

[0007] Preferably, in the processing technology of the high-temperature alloy irregular sleeve-type parts, the irregular inclined groove in step S5 is fan-shaped, and the irregular inclined groove is arranged at equal intervals around the circumference of the first stage between the inner and outer cylinders.

[0008] Preferably, in the processing technology of the high-temperature alloy irregular sleeve-type parts, the irregular groove in step S7 includes a first irregular section, a second irregular section and a third irregular section. One end of the first irregular section is connected to one end of the inner cylinder near the second stage, and the other end extends to the end of the conical section. The second irregular section is disposed between the back of the irregular inclined groove and the outer wall of the inner cylinder, and the third irregular section is disposed between the first irregular section and the second irregular section.

[0009] Preferably, in the processing technology of the high-temperature alloy irregular sleeve-type parts, both the first irregular segment and the third irregular segment are arc-shaped.

[0010] Preferably, in the processing of the high-temperature alloy irregular sleeve-type parts, the first tooling in steps S5 and S6 includes a positioning seat and pressure plate assemblies disposed on both sides of the positioning seat, wherein the positioning seat has a positioning hole in the middle that mates with the three outer circles of the workpiece.

[0011] Preferably, in the processing technology of the high-temperature alloy irregular sleeve-type parts, the pressure plate assembly includes a support rod disposed on the positioning seat and a clamping member disposed on the top of the support rod. The clamping member includes a fixed section connected to the support rod and a clamping section perpendicularly connected to the fixed section. The clamping section is L-shaped.

[0012] Preferably, in the processing of the high-temperature alloy irregular sleeve-type parts, the second tooling in step S9 includes a base plate, a second positioning seat is provided on the base plate, a screw is provided on the second positioning seat, and the first stage is sleeved on the screw and pressed by a pressure plate.

[0013] A high-temperature alloy irregularly shaped sleeve-like part is characterized by comprising a first stage and a second stage. The first stage includes an inner cylinder and an outer cylinder. The inner cylinder has a stepped hole with a diameter smaller than that of the second stage. An irregularly shaped inclined groove is provided between the inner and outer cylinders. The irregularly shaped inclined groove is arranged at equal intervals around the circumference of the first stage between the inner and outer cylinders. An irregularly shaped groove is provided between the outer wall of the inner cylinder and the back of the irregularly shaped inclined groove. The irregularly shaped groove includes a first irregularly shaped section, a second irregularly shaped section, and a third irregularly shaped section.

The third irregularly shaped section is provided between the first and second irregularly shaped sections. The irregularly shaped groove is an arc-shaped groove.

[0014] The present invention has the following advantages: (1) The processing technology of the high temperature alloy irregular sleeve parts of the present invention is as follows: because the inner hole of the part is large and the cutting force during the processing is large, the process considers drilling as the first processing step of the whole process flow, and uses a violent U-drill to rough process most of the allowance, thereby improving the processing efficiency of the part.

[0015] (2) The processing technology of the high temperature alloy irregular sleeve parts of the present invention has a large overall machining allowance and is prone to deformation during the processing, which makes it impossible to meet the requirements of high precision dimensional tolerance. Therefore, the process route needs to be processed in the manner of rough-finish machining to reduce the deformation generated during the processing.

[0016] (3) The processing technology of the high temperature alloy irregular sleeve parts of the present invention. These parts are made of high temperature alloy materials. These materials are difficult to cut and easy to produce work hardening. In particular, when processing irregular internal cavity structures, the tool consumption is very high due to the small machining radius, which increases the processing cost of the parts. Therefore, the process route is to perform wire cutting rough machining of irregular grooves and electrical discharge machining of one end and the other end of the irregular inclined grooves, thereby reducing tool consumption and reducing tool cost.

[0017] (4) In the processing technology of the high temperature alloy irregular sleeve parts of the present invention, when the irregular inclined groove is precision machined by electrical discharge machining, considering that the amount of material removed is large and the electrode is consumed quickly, two electrodes are required for roughing and finishing in the process; when the ACME external thread end is precision machined, a special plug is required to be designed to position the inner hole and the end face, thereby improving the stability of the processing.

[0018] (5) The processing technology of the high temperature alloy irregular sleeve parts of the present invention can fully meet the various characteristics of the parts and effectively avoid the influence of part deformation on processing and final product. At the same time, it can greatly reduce the consumption of tools and can be widely promoted in the processing of similar parts. Attached Figure Description
