Description
Technical field
The invention belongs to thin-wall pipe cutting technique field, be specifically related to the cutting of a kind of built-in thin-wall copper pipe
Device.
Background technology
The expansion tube process method of current large-scale finned tube exchanger all uses manual tube expansion, so can cause copper
Pipe exposes end plate apart from inconsistent, to this end, traditional method is to cut unnecessary size with shears is manual, because of
And can cause: manual line, waste time and energy, and mouth of pipe dimensional uniformity of appearing is poor after shearing;When with cutting
During cutter manual shearing copper pipe, shear direction randomness is relatively big, causes cut-out direction not parallel with end plate, and
Affect the smooth enforcement of follow-up set elbow and welding sequence, also affect the overall appearance quality of product;Copper pipe
Swollen complete rear tube wall is thinning, mouth of pipe gross distortion after scissor cut, needs full circle again, and mouth of pipe full circle
After cannot deformation all eliminate, bring difficulty to postorder processing.Therefore, it is necessary to improve.
Summary of the invention
Present invention solves the technical problem that: provide a kind of built-in thin-wall copper pipe sickle, by by tubular
Cutting knife is placed in inside copper pipe to be processed together with pull bar, swollen head, then adjusts swollen head position and make swollen head move upward,
So that tubular cutting knife expands, produce radial feeds, when tubular cutting knife blade contacts with copper pipe to be processed
Time, the handle that turns clockwise makes its band motion rocker arm and then drives pull bar to move in a circle with tubular cutting knife, cutting
Cut copper pipe.Continue to strengthen the radial feeds of tubular cutting knife, until cutting off copper pipe.Built-in thin-wall copper pipe
Sickle simple in construction, easy to use, mouth of pipe rounding is without deformation.
The technical solution used in the present invention: built-in thin-wall copper pipe sickle, has tubular cutting knife, described cylinder
Axle sleeve it is set with, in described axle sleeve is placed in the hole of bearing upper end and the lower end of axle sleeve positioning boss on shape cutting knife
Face is affixed with bearing upper surface, and described tubular cutting knife top is set with rocking arm and rocking arm is placed on axle sleeve, institute
Stating and be shaped with screwed hole outside one end, location screw makes it through the side opening on screwed hole and tubular cutting knife
End is placed in the locating slot of tubular cutting knife draw-in bar, and the described rocking arm other end is provided with handle, described tubular
Cutting knife upper end is provided with wing nut and wing nut and threadeds with pull bar top, and described pull bar lower end is provided with
Swollen head, screw connects through the screw of swollen head and tie rod end and is integrated.
Wherein, described tubular cutting knife lower end outer wall face is provided with blade and tubular cutting knife lower end outside is shaped with longitudinal direction
Otch.
Further, described swollen head is the external diameter internal diameter more than tubular cutting knife of coniform and swollen head.
Further, it is provided with two locking nuts in the middle part of described tubular cutting knife and is placed in the lower end of axle sleeve.
Present invention advantage compared with prior art:
1, after the bearing of sickle is placed in end plate plane, from tubular cutting knife lower surface to bearing lower surface
Size will not change, and during cutter cuts, bearing is motionless.Both ensure that the end plate that do not weares and teares, ensured again
The mouth of pipe required after cutting is appeared size and the concordance of size of appearing.
2, ensure that copper pipe cut-out direction is parallel with end plate, mouth of pipe rounding is without deformation.
3, tubular cutting knife external diameter is the least with copper pipe internal diameter gap, can play apotting spindle effect, make each copper pipe
The nonparallelism appeared reduces.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram;
Fig. 2 is tubular cutting knife end face structure schematic diagram.
Detailed description of the invention
1, the 2 a kind of embodiment describing the present invention below in conjunction with the accompanying drawings.
Built-in thin-wall copper pipe sickle, has tubular cutting knife 1, described tubular cutting knife 1 is set with axle sleeve
2, it is provided with two locking nuts 15 in the middle part of described tubular cutting knife 1 and is placed in the lower end of axle sleeve 2, described two
Individual locking nut 15 can mutually self-locking, thus can ensure from tubular cutting knife 1 lower surface to bearing 3 lower surface
Size keep constant, the copper pipe adjusted the most in advance size of appearing keeps constant.Described axle sleeve 2 is placed in
In the hole of bearing 3 upper end and the lower surface of axle sleeve 2 positioning boss 4 is affixed with bearing 3 upper surface, 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
Being shaped with screwed hole 6, location screw 7 makes its end put through the side opening 9 on screwed hole 6 and tubular cutting knife 1
In the locating slot 8 of tubular cutting knife 1 draw-in bar 10, 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 and threadeds with pull bar 10 top, institute
State pull bar 10 lower end and be provided with swollen 12, screw 13 through the screw of swollen 12 and pull bar 10 end by it
Connecting as one, concrete, described tubular cutting knife 1 lower end outer wall face is provided with blade 16 and tubular cutting knife 1
Lower end outside is shaped with longitudinal cut 14, and described copper pipe cutting knife 1 is selected has the most elastic high-quality steel,
During pull bar 10 drives and moves on swollen 12, tubular cutting knife 1 is forced to expand.Described swollen 12 is circle
The external diameter of taper and swollen 12 is more than the internal diameter of tubular cutting knife 1.
During work, tubular cutting knife 1 is connected pull bar 10, is placed in copper pipe 19 inner chamber for swollen 12, make to prop up
It is close to end plate 18 bottom seat 3, adjusts copper the most in advance by the mutual self-locking action of two locking nuts 15
The size of appearing of pipe 19, i.e. tubular cutting knife 1 lower surface is to the size of bearing 3 lower surface, at cutting process
Middle holding is constant, tightens wing nut 11, make pull bar 10 and swollen 12 move up, so that tubular
Cutting knife 1 lower end expands, and produces radial feeds, when tubular cutting knife blade 16 and copper pipe 19 contact internal walls
Time, turn clockwise handle 17 so that it is drives Rocker arm 5 to drive cylinder centered by the axis of tubular cutting knife 1
Shape cutting knife 1 moves in a circle, and makes blade 16 cut copper pipe 19, continues to tighten wing nut 11,
Strengthen amount of feeding when tubular cutting knife 1 lower end cutter 16 cuts, until cutting off copper pipe 19.Described bearing 3
Being provided with observation window, whether observable copper pipe 19 cuts off, and whether locking nut 15 unclamps.Cutting completes
Mouthful, inverting wing nut 11, make pull bar 10 drive swollen 12 to move down, tubular cutting knife 1 lower end is shunk,
Until after original state, the clout cut off being taken out.When the blade 16 on tubular cutting knife 1 is due to abrasion
When being difficult to cut copper pipe 19, only need to pull down tubular cutting knife 1, blade thereon be repaired a die a little or more creeling
Shape cutting knife 1, by changing the bearing 3 of differing heights size, can realize copper pipe 19 difference and appear chi
Very little requirement.
Above-described embodiment, simply presently preferred embodiments of the present invention, be not used for limiting the scope of the present invention,
Therefore all with content described in the claims in the present invention done equivalence change, all should be included in right of the present invention want
Within the scope of asking.
