Abstract
The invention discloses a method for the cutting processing of an ultra-long straight type pipeline. Firstly, a pipe end expansion piece for the ultra-long pipeline is manufactured, and the pipe end expansion piece consists of a connecting part, at least three expansion pieces evenly arranged and thimble holes arranged in the center of the end parts of the expansion pieces, and a clearance is reserved between each two expansion pieces; a processing pipeline is inserted into a clamping disk, and a pipeline piece is pre-tightened by a claw; the pipe end expansion piece is inserted into the pipeline; the rotary thimbles are pushed in the thimble holes of the pipe end expansion piece; the expansion pieces are expanded and deformed along the radial direction to tightly press against the internal diameter of the pipeline so as to generate the pretension expansion force; and the claw is fastened again; a main shaft is rotated, the cutting feed is performed, and the processing beings. With the mode adopted, the method has the advantages of ensuring the processing quality and safety, improving the production efficiency and lowering the production cost, along with convenient processing operation.
Description
Technical field
The present invention relates to a kind of cutting working method of overlength straight pipeline member.
Background technology
Finished product duct products, the cylindrical of its pipeline often need be carried out turning processing, to reach higher surface smoothness and dimensional accuracy.What the machining of overlength straight pipeline member adopted at present is horizontal lathe, rely on the claw clamping work pieces of self, processing center of gravity reach because of the overlength pipeline member, under the Work piece high-speed rotation, workpiece and lathe spindle rotation, do not overlap slightly, just can cause acutely beating of workpiece, thereby be difficult to guarantee crudy and process safety; Sometimes, for guaranteeing normally carrying out of turning processing, on the pinching end opposite, use center apical pore or A-frame or the processing of follow-rest location, but this type of process maybe should not be adopted or the procedure complexity is difficult to enhance productivity and reduce cost.
Summary of the invention
Technical problem to be solved by this invention is: the cutting working method that a kind of overlength straight pipeline member is provided, the smear metal processing method of this overlength straight pipeline member had both made things convenient for process operation, can guarantee crudy and safety again, enhance productivity, reduce production costs.
Solve this technical problem, technical scheme of the present invention is: a kind of smear metal processing method of overlength straight pipeline member, it comprises the steps:
A, make the pipe end swelling part be used for overlength straight pipeline member, this pipe end swelling part comprises connecting portion, uniform swelling sheet and be positioned at the centre hole at center, swelling sheet end more than three, all has the gap between each tensioner sheet.
B, overlength straight pipeline member is inserted in the lathe chuck and pre-the clamping, tentatively adjust the balance and the rotation of pipeline member, making its rotation and lathe spindle is coaxial line;
C, adjust the lathe tailstock center, make the axle center center line and the same axis of main axis rotation of tailstock thimble; Described pipe end swelling part is put into the end of overlength straight pipeline member, the tailstock thimble is headed in the swelling part centre hole;
D, shake the tailstock rotary disk, by the tailstock thimble swelling sheet of swelling part is radially risen and expand displacement and tighten internal diameter of the pipeline;
E, locking lathe tailstock and fastening chuck start main shaft, the processing of feed beginning;
Described pipe end swelling part has four swelling sheets.
The tension member of the end cover single-revolution body of described tailstock thimble, this tension member is made up of bulb and shrinking section, and shrinking section has the vertebral foramen that adapts with the tailstock thimble.
Described lathe tailstock is general bolting type.
Described thimble is the activity swinging.
The cutting working method of a kind of overlength straight pipeline member of the present invention is adopted in such a way, has overcome in the prior art, and overlength straight pipeline member is difficult to carry out conveniently machining; By making special-purpose pipe end swelling part, and pipe end swelling part put into the overlength straight pipeline member pipe hole, utilize the radially tensioner distortion of pipe end swelling part, make the two ends of overlength straight pipeline member be able to stationary positioned, this had both made things convenient for process operation, can guarantee crudy and safety again, enhance productivity, reduce production cost.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the cutting working method of a kind of overlength straight pipeline member of the present invention, its step is as follows:
A, manufacturing are used for the pipe end swelling part 3 of overlength straight pipeline member, and this pipe end swelling part 3 comprises swelling sheet 6 that connecting portion 8, quartering cutting process become and the swelling part centre hole 7 that is positioned at center, swelling sheet 6 end, all has gap 9 between each tensioner sheet 6.Described pipe end swelling part 3 materials are the GCr15 steel, through surface hardening and modifier treatment, require to have higher surface hardness (more than the HRC55) and elasticity toughness; Swelling part centre hole 7 has the gradient that adapts with the tailstock thimble, and has higher surface and positional precision.When tension member at the end of tailstock thimble cover single-revolution body, this tension member is made up of bulb 10 and shrinking section 11, shrinking section 11 has the vertebral foramen that adapts with the tailstock thimble, and the circular arc of diameter less than tension member bulb 10 diameters is processed in swelling part centre hole 7 ends of pipe end swelling part 3.
B, overlength straight pipeline member 4 is inserted in the lathe chucks 5, rotary pawl screw, claw carry out radial displacement and pretension pipeline cylindrical, tentatively adjust the balance and the rotation of pipeline member, and making its rotation and lathe spindle is coaxial line;
C, adjust lathe tailstock 1 center, make the axle center center line and the same axis of main axis rotation of tailstock thimble; Put into pipe end swelling part 3, simultaneously lathe rotation thimble 2 is put into lathe tailstock 1 taper hole, promote and locking lathe tailstock 1, lathe rotation thimble 2 is headed in the pipe end swelling part centre hole 7;
D, pipe end swelling part 3 are subjected to the effect of lathe rotation thimble, and pintongs swelling sheet 6 produces radially expanding distortion, thus the tensioner internal diameter of the pipeline;
E, fastening claw 5 once more, institute steps up power and is as the criterion not produce pipe deforming, rotary main shaft, the processing of feed beginning.
