Description
Technical field
The invention belongs to thin-wall pipe cutting technique field, be specifically related to a kind of built-in thin-wall copper pipe cutter.
Background technology
The expansion tube process method of current large-scale finned tube exchanger all adopts manual expand tube, can cause like this copper pipe to expose end plate distance inconsistent, for this reason, traditional method is to cut by hand unnecessary size with scissors, thereby can cause: manual line, waste time and energy, and after shearing, the mouth of pipe dimensional uniformity of appearing is poor; When shearing copper pipe with scissors is manual, shear direction randomness is larger, causes cut-out direction and end plate not parallel, and affects the smooth enforcement of follow-up cover elbow and welding sequence, also affects the overall appearance quality of product; Complete rear tube wall attenuation that copper pipe is swollen, mouth of pipe gross distortion after scissor cut, needs full circle again, and distortion all cannot be eliminated after mouth of pipe full circle, and to postorder, processing brings difficulty.Therefore, be necessary to improve.
Summary of the invention
The technical problem that the present invention solves: a kind of built-in thin-wall copper pipe cutter is provided, by tubular cutting knife is placed in to copper pipe to be processed inside together with pull bar, swollen head, adjusting swollen position moves upward swollen head again, thereby tubular cutting knife is expanded, produce radial feeds, when tubular cutting knife blade contacts with copper pipe to be processed, the handle that turns clockwise makes it drive rocking arm and then drives pull bar and tubular cutting knife to move in a circle, cutting copper pipe.Continue to strengthen the radial feeds of tubular cutting knife, until cut off copper pipe.Built-in thin-wall copper pipe cutter is simple in structure, easy to use, and mouth of pipe rounding is without distortion.
The technical solution used in the present invention: built-in thin-wall copper pipe cutter, there is tubular cutting knife, on described tubular cutting knife, be set with axle sleeve, described axle sleeve is placed in the hole of bearing upper end and lower surface and the bearing upper surface of axle sleeve positioning boss are affixed, described tubular cutting knife top is set with rocking arm and rocking arm is placed on axle sleeve, outside, described rocking arm one end is shaped with screwed hole, dog screw is placed in the locating slot of tubular cutting knife draw-in bar its end through the side opening on screwed hole and tubular cutting knife, the described rocking arm other end is provided with handle, described tubular cutting knife upper end is provided with wing nut and wing nut is threaded with pull bar top, described pull bar lower end is provided with swollen head, screw connects and is integrated through the screw of swollen head and tie rod end.
Wherein, described tubular cutting knife lower end outside wall surface is provided with blade and tubular cutting knife lower end outside and is shaped with longitudinal cut.
Further, the external diameter that described swollen head is coniform and swollen head is greater than the internal diameter of tubular cutting knife.
Further, described tubular cutting knife middle part is provided with two locking nuts and is placed in the lower end of axle sleeve.
The present invention's advantage compared with prior art:
1, the bearing when cutter is placed in after end plate plane, and the size from tubular cutting knife lower surface to bearing lower surface can not change, and during cutter cuts, bearing is motionless.Both guarantee the end plate that do not wear and tear, guaranteed again the appear uniformity of size and the size of appearing of the required mouth of pipe after cutting.
2, guaranteed that copper pipe cut-out direction is parallel with end plate, mouth of pipe rounding is without distortion.
3, tubular cutting knife external diameter and copper pipe internal diameter gap are very little, can play apotting spindle effect, and the nonparallelism that each copper pipe is appeared reduces.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is tubular cutting knife end face structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing 1,2, a kind of embodiment of the present invention is described.
Built-in thin-wall copper pipe cutter, there is tubular cutting knife 1, on described tubular cutting knife 1, be set with axle sleeve 2, described tubular cutting knife 1 middle part is provided with two locking nuts 15 and is placed in the lower end of axle sleeve 2, described two locking nut 15 self-lockings mutually, thereby can guarantee that the size from tubular cutting knife 1 lower surface to bearing 3 lower surfaces remains unchanged, the copper pipe of adjusting the in advance size of appearing remains unchanged.Described axle sleeve 2 is placed in the hole of bearing 3 upper ends and lower surface and bearing 3 upper surfaces of axle sleeve 2 positioning boss 4 are affixed, described tubular cutting knife 1 top is set with Rocker arm 5 and Rocker arm 5 is placed on axle sleeve 2, outside, described Rocker arm 5 one end is shaped with screwed hole 6, dog screw 7 is placed in the locating slot 8 of tubular cutting knife 1 draw-in bar 10 its end through the side opening 9 on screwed hole 6 and tubular cutting knife 1, the described Rocker arm 5 other end is provided with handle 17, described tubular cutting knife 1 upper end is provided with wing nut 11 and wing nut 11 is threaded with pull bar 10 tops, described pull bar 10 lower ends are provided with swollen 12, screw 13 connects and is integrated through the screw of swollen 12 and pull bar 10 ends, concrete, described tubular cutting knife 1 lower end outside wall surface is provided with blade 16 and tubular cutting knife 1 outside, lower end is shaped with longitudinal cut 14, described copper pipe cutting knife 1 is selected has better flexible high-quality steel, on driving swollen 12, pull bar 10 moves past in journey, force tubular cutting knife 1 to expand.Described swollen 12 is greater than the internal diameter of tubular cutting knife 1 for the external diameter of coniform and swollen 12.
During work, tubular cutting knife 1 is communicated with to pull bar 10, be placed in copper pipe 19 inner chambers for swollen 12, make bearing 3 bottoms be close to end plate 18, by the mutual self-locking action of two locking nuts 15, adjust in advance the size of appearing of copper pipe 19, be that tubular cutting knife 1 lower surface is to the size of bearing 3 lower surfaces, in cutting process, remain unchanged, tighten wing nut 11, pull bar 10 and swollen 12 are moved up, thereby expanded in tubular cutting knife 1 lower end, produce radial feeds, when tubular cutting knife blade 16 contacts with copper pipe 19 inwalls, handle 17 turns clockwise, make it drive Rocker arm 5 centered by the axis of tubular cutting knife 1, to drive tubular cutting knife 1 to move in a circle, 16 pairs of copper pipes 19 of blade are cut, continue to tighten wing nut 11, the amount of feeding while strengthening 1 lower end cutter 16 cutting of tubular cutting knife, until cut off copper pipe 19.Described bearing 3 is provided with observation window, and whether observable copper pipe 19 cuts off, and whether locking nut 15 unclamps.Cut mouth, reversion wing nut 11, makes pull bar 10 drive swollen 12 to move down, and shrink tubular cutting knife 1 lower end, until after original state, the clout cutting off is taken out.When the blade 16 on tubular cutting knife 1 is difficult for cutting copper pipe 19 due to wearing and tearing; only need pull down tubular cutting knife 1; blade on it repaired a die a little or change tubular cutting knife 1, by changing the bearing 3 of differing heights size, can realize the appear requirement of size of copper pipe 19 differences.
Above-described embodiment, is preferred embodiment of the present invention, is not used for limiting the scope of the present invention, and the equivalence of being done with content described in the claims in the present invention therefore all changes, within all should being included in the claims in the present invention scope.
