Abstract
The utility model discloses a thin-wall steel tube cutting device and relates to the steel pipe machining technology. In a steel cutting process, steel pipes are cut and at the same time, notches of the steel pipes are instantly trimmed and the cutting quality is ensured. The two ends of cut pipes are flat and free of burr. The length of cut pipes is accurate and cutting errors are less. Two faces of a cutting blade are abraded at the same time and abrasion of a cutter will not affect cutting precision. A chamfer cutter is provided with six blade faces. After abrasion, blade faces can be replaced at first, the frequency of sharpening the cutter is reduced and the production efficiency is improved.
Description
Technical field
The utility model relates to steel pipe process technology, and specifically a kind of thin-wall steel tube cuts off technology.
Background technology
At present, the cut-out mode of steel pipe mainly contains: alloy saw is sawed-off, grinding wheel rubs and the disconnected three kinds of modes of cold-extruded, the common shortcoming that these three kinds of modes all have is that the fracture burr of the steel pipe after cutting off is large, and outer surface scratch is serious, and next process is produced to larger harmful effect, and the length accuracy of the steel pipe that three kinds of cut-out modes cut out is not high, the production higher to required precision, as the production of stainless steel kettle, affects very large.
Utility model content
The deficiency that the utility model exists in order to overcome prior art, provides a kind of cutting-off method of thin-wall steel tube and realizes the device of the method.
The utility model can be by taking following technical scheme to be achieved:
A kind of shearing device of thin-wall steel tube, comprise steel pipe carriage and instrument lathe, described steel pipe carriage is connected with the charging aperture of instrument lathe, on described instrument lathe, be provided with rotatable electric chuck, described electric chuck is communicated with described charging aperture, described electric chuck end arranged outside has cutting off tool assembly, described cutting off tool assembly is arranged on instrument lathe, described cutting off tool assembly comprises fracture cutter, rose reamer and the automatic tool frame that can slide perpendicular to electric chuck rotary middle spindle, described fracture cutter and rose reamer are arranged on respectively the both sides of automatic tool frame.
On described instrument lathe, be provided with the positioning baffle adjustable with cutting off tool assembly distance, the rotary middle spindle of described positioning baffle and electric chuck intersects vertically.
The sword of described fracture cutter is facing to positioning baffle, and the sword of described rose reamer is facing to electric chuck.
Preferably, described fracture cutter adopts the manufacture of wolfram steel material, and described rose reamer adopts the alloy knife that model is TNMG.
Compared with prior art, the beneficial effects of the utility model are: the materials in the tube two ends of the blanking that this programme is produced are all smooth, without burr; The length of blanking is accurate, and error is little; Wear and tear in fracture cutter two sides simultaneously, tool wear does not affect blanking precision; Rose reamer has six sword faces, after wearing and tearing, can first change sword face, reduces sharpening number of times, enhances productivity.

The specific embodiment
Below in conjunction with accompanying drawing, most preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, a kind of shearing device of thin-wall steel tube, comprise steel pipe carriage and instrument lathe 6, carriage comprises materials in the tube support 1, on materials in the tube support 1, be provided with materials in the tube push rod 2, materials in the tube push rod 2 is pulled by draught line 3 by weight 4, and on materials in the tube support 1, placing steel tubes 12, and steel pipe 12 is promoted by materials in the tube push rod 2.
The materials in the tube support 1 of steel pipe carriage is connected with the charging aperture of instrument lathe 6, steel pipe 12 is pushed in instrument lathe 6, on instrument lathe 1, be provided with rotatable electric chuck 8, electric chuck 8 is communicated with charging aperture, electric chuck 8 drives rotation by the motor 5 that is located on instrument lathe 6, electric chuck 8 end arranged outside have cutting off tool assembly, cutting off tool assembly is arranged on instrument lathe 6, as shown in Fig. 2～4, cutting off tool assembly comprises fracture cutter 10, rose reamer 11 and the automatic tool frame 9 that can slide perpendicular to electric chuck rotary middle spindle, fracture cutter 10 and rose reamer 11 are arranged on respectively the both sides of automatic tool frame 9.
As Figure 1 and Figure 4, be provided with the positioning baffle 7 adjustable with cutting off tool assembly distance on instrument lathe 1, positioning baffle 7 intersects vertically with the rotary middle spindle of electric chuck 8.
As shown in Fig. 2～4, the sword of fracture cutter 10, facing to positioning baffle 7, makes the fracture of blanking 13 smooth like this, and the sword of rose reamer 11, facing to electric chuck 8, is done like this and can be made the fracture of steel pipe 12 smooth.The edge direction setting of two cuttves is all smooth equally in order to guarantee the two ends of blanking 13.
The course of work and step:
A, electric chuck 8 unclamp, steel pipe will be pushed out electric chuck 8, when newly, put into a steel pipe 12, can be pushed out and just control electric chuck 8 in a bit of and clamp steel pipes 12 at steel pipe 12, then starter motor 5 rotates electric chuck 8, and toolframe 9 slides to the direction of rose reamer 11, makes fracture cutter 10 to steel pipe 12 feeds, a bit of cut-out to steel pipe front portion is removed, as shown in Figure 2.
B, after the cut-out of step a or steps d has been moved, toolframe 9 slides to the direction of fracture cutter 10, makes rose reamer 11 to steel pipe 12 feeds, with chamfering 11 cuttves to the fracture of steel pipe 12 be rotated excise crude, as shown in Figure 3.
C, after step b completes, motor 5 is shut down, electric chuck 8 unclamps, steel pipe 12 is pushed out, until steel pipe 12 is pulled to positioning baffle 7, is adjacent to, and completes steel pipe 12 is positioned, as shown in Figure 4.
Behind the steel pipe location of d, completing steps c, electric chuck 8 clamps steel pipe 12, motor 5 starts, electric chuck 8 rotates with steel pipe 12, toolframe 9 slides to the direction of rose reamer 11, makes fracture cutter 10 to steel pipe 12 feeds, with 10 pairs of steel pipes of fracture cutter, is rotated and cuts off output blanking 13, (fracture operation is identical with the operation of step a, but operation object is different) as shown in Figure 2.
Every steel pipe is carried out to a, b step before blanking for the first time, guarantee that the precision of blanking is also qualified for the first time, blanking loops b, c, d step later for the first time, continuous production blanking 13, after each feed step finishes, all need withdrawing, in order to avoid affect next step operation and damage cutter.
Only as described above, it is only the preferred embodiment of the utility model, when not limiting with this scope of the utility model enforcement, the content of generally recording according to the utility model claim and utility model description has been done simple equivalence and has been changed and modify, within all still belonging to the utility model claim scope.In addition, summary part and title are only the use for auxiliary patent document search, are not used for limiting the interest field of the utility model.
