Description
Technical field
The utility model has related to a kind of tool joint friction welding (FW) servicing unit, particularly a kind of drill pipe friction joint endoporus overlap removal device.
Background technology
The raw material of drilling rod production is joint and body.By friction welding body and joint are connected into an adult.The welding back will form overlap in the commissure, and the traditional handicraft of removing overlap is turning.In recent years, joint is more and more longer, the joint internal diameter is more and more littler, make that the slenderness ratio of turning knife bar is increasing, the phenomenon of cause the cutter that shakes, forging a knife is more and more, has a strong impact on working (machining) efficiency, also increased the equipment cost of product, when slenderness ratio is about 1/10, just can not use turning process again,, seek additive method and remove overlap so must change technology.
The utility model content
Technical problem to be solved in the utility model provides a kind of drill pipe friction joint endoporus overlap removal device, it can use the punching cutter of different structure that the overlap that friction welding (FW) forms is removed according to the transposing of the relation between hole dimension in the tool joint and the friction welding area of bed, effectively prevent to use turning process to remove to forge a knife in the overlap process appearance of phenomenon, improve the friction welding (FW) overlap and remove technology, enhance productivity.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of drill pipe friction joint endoporus overlap removal device comprises hydraulic cylinder and punching cutter as power source; Described punching cutter be used to remove the hydrophthalmia diameter equal the welding ends aperture tool joint friction welding (FW) overlap first kind of punching cutter or be used to remove the second kind punching cutter of hydrophthalmia diameter less than the tool joint friction welding (FW) overlap in welding ends aperture; Described first kind of punching cutter is the cylinder-like structure of end sealing, and its open end is provided with the spiral edge of a knife, and blind end is provided with internal thread; Described first kind of punching cutter blind end is connected with the push rod end thread of described hydraulic cylinder; Described second kind of punching cutter comprises round platform section and the cylindrical section that fixes as one, and is provided with the spiral edge of a knife in the end of cylindrical section.
Adopt the beneficial effect that technique scheme produced to be: the overlap of wiping out the joint that produces because of friction welding (FW) with the punching cutter from tool joint inside, the punching cutter uses round tube shape structure, and generally adopt in the prior art turning process, increase along with tool joint length, the slenderness ratio of cutting tool knife bar is more and more littler, the production accident that knife bar ruptures occurs through regular meeting, directly influence production efficiency and crudy, also can increase equipment cost; Use the punching cutter disclosed in the utility model then not have the problems referred to above, and the structure of the punching cutter in the utility model is to be provided with according to the relation between hole dimension in the tool joint and the joint area size, select the punching cutter of different structure for use according to the structure of different tool joints, improve the tool joint overlap greatly and remove efficient, can also improve crudy, reduce the equipment cost of product.

1, first kind of tool joint (the drill pipe bore size equals the joint size); 1-1, tool joint internal thread link; 1-2, tool joint endoporus; The friction welding head end of 1-3, tool joint; 2, second kind of tool joint (the drill pipe bore size is less than the joint size); 2-1, tool joint external screw thread link; 2-2, tool joint endoporus; 2-3, tool joint friction welding head end; 3, first kind of punching cutter; The spiral edge of a knife end of 3-1, first kind of punching cutter; 4, second kind of punching cutter; The spiral edge of a knife end of 4-1, second kind of punching cutter; The round platform section of 4-2, second kind of punching cutter; 5, hydraulic cylinder; 6, push rod; Further the utility model is described in detail below in conjunction with accompanying drawing.
The specific embodiment
, it is characterized in that: comprise hydraulic cylinder 5 and punching cutter to a kind of drill pipe friction joint endoporus overlap removal device shown in Figure 6 as Fig. 1 as power source; Described punching cutter be used to remove the hydrophthalmia diameter equal the welding ends aperture tool joint friction welding (FW) overlap first kind of punching cutter 3 or be used to remove the second kind punching cutter 4 of hydrophthalmia diameter less than the tool joint friction welding (FW) overlap in welding ends aperture; Described first kind of punching cutter 3 is the cylinder-like structure of end sealing, and its open end is provided with the spiral edge of a knife, and blind end is provided with internal thread; Described first kind of punching cutter 3 blind end are connected with the push rod end thread of described hydraulic cylinder 5; Described second kind of punching cutter 4 comprises round platform section 4-1 and the cylindrical section 4-2 that fixes as one, and is provided with the spiral edge of a knife in the end of cylindrical section 4-2; When first kind of tool joint being carried out the overlap removal, select first kind of punching cutter for use, because the interior hole dimension of first kind of tool joint equals the size that jackrod structure and drilling rod carry out the friction welding (FW) end, first kind of punching cutter adopts with the hydraulic cylinder push rod and is threaded, the welding position be in also be in the red heat state in, the first kind of punching cutter that uses Driven by Hydraulic Cylinder to be installed in hydraulic cylinder push rod end stretches into the overlap that produces in the punching friction welding (FW) process the tool joint endoporus from the non-welding ends of tool joint;
To second kind of tool joint, be that hole dimension carries out selecting for use when overlap is removed second kind of punching cutter less than friction welding head end inside dimension in the tool joint, because the outside dimension of second kind of punching cutter is greater than the hydrophthalmia size of tool joint, so second kind of punching cutter is the using method that can not adopt first kind of punching cutter, should before carrying out friction welding (FW), just second kind of punching cutter be inserted in the endoporus of tool joint friction welding head end, non-welding ends stretches into the overlap that produces when impacting second kind of punching cutter punching friction welding (FW) the tool joint endoporus from tool joint with the hydraulic cylinder push rod after friction welding (FW) welding finishes, and the artificial overlap that second kind of punching cutter and punching are got off was poured out from drilling rod or hook goes out to get final product after punching finished; Adopt the drill pipe friction joint endoporus overlap removal device disclosed in the utility model, can improve the tool joint overlap greatly and remove efficient, effectively avoid having forging a knife and the cutter phenomenon of shaking of being easy to generate in the Cutting Process now, also can effectively reduce the equipment cost of product.
