Abstract
The utility model discloses a pipeline protective case opening instrument, through offering logical groove along the axis on the empty cardioid positioning core axle pipe wall of cylinder, then there is the cutting knife at the logical inslot of positioning core axle through the round pin axle is articulated, it is articulated with setting spindle through the round pin axle, the cutting knife opens and shuts around the round pin rotation of axes, when the cutting knife is opened, protect the ways on setting spindle the pipeline, the pipeline protective sheath is open to the cutting knife closure, the material that cuts down falls into setting spindle's interstitial hole, heated and exhausted, pipeline protective sheath incision does not have the turn -ups, and no burr exists, simple operation, simple maintenance, low cost. Wherein the cutting knife lower extreme cuts sword, the accurate and difficult deckle edge that produce of cutting for bitangent, the cutting knife other end is fixed with the handle, is favorable to cutting the application of force.
Description
Technical field
The utility model belongs to machining class instrument, and in particular to a kind of pipeline protective sleeve tube opening instrument.
Background technology
In engine pipelines, need to fix pipeline with pipe collar, in order to protect pipeline, protected with flexiplast class pipeline
Set (pad) is padded between pipe collar and pipe, after preventing pipe collar from tightening, causes pipeline to weigh wounded；Pipeline protective sleeve (is padded), general to adopt
Tube-in-tube structure, for the ease of protective case (pad) being enclosed within pipeline during assembling, in protective case (pad) one or both sides opening.It is former to add
Work technique adopts Milling Process, but opening hole flanging, and burrs on edges is big, and opening size is wayward.
Utility model content
The purpose of this utility model is to provide a kind of pipeline protective sleeve tube opening instrument, to overcome prior art not
Foot.
For reaching above-mentioned purpose, the utility model is adopted the following technical scheme that：
A kind of pipeline protective sleeve tube opening instrument, including the positioning core axle of cylinder hollow shape, along axle on positioning core axle tube wall
Line offers groove, has cutter by hinge in the groove of positioning core axle, and the cutter other end is fixed with handle.
Further, groove and positioning core axle endoporus insertion.
Further, handle is fixed or is welded on cutter by rivet.
Further, on positioning core axle tube wall, groove both sides are axially arranged with opening.
Further, wherein cutter lower end is double cutting edges.
Further, its middle groove A/F is more than cutter thickness.
Further, the cutter other end is fixed with handle.
Compared with prior art, the utility model has following beneficial technique effect：
A kind of pipeline protective sleeve tube opening instrument of the utility model, by the positioning core axle tube wall including cylinder hollow shape
On offer groove along axis, then have cutter by hinge in the groove of positioning core axle, by bearing pin and positioning
Heart axle is hinged, and cutter, pipeline protective sleeve are enclosed within apotting spindle, cutter when cutter are opened around bearing pin rotating folding
Pipeline protective sleeve is cut by closure, and the material for cutting down falls into the interstitial hole of apotting spindle, is then discharged out, and pipeline protective sleeve is cut
, without flange, impulse- free robustness is easy to operate for mouth, safeguards simple, low cost.
Further, wherein cutter lower end is double cutting edges, and cutting is accurate and does not allow to be also easy to produce burr.
Further, the cutter other end is fixed with handle, is conducive to cutting force.

Fig. 3 is the utility model cutter end view drawing.
Wherein, 1, positioning core axle；2nd, bearing pin；3rd, cutter；4th, handle；5th, rivet.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail：
As shown in Figure 1 to Figure 3, a kind of pipeline protective sleeve tube opening instrument, it is including the positioning core axle 1 of cylinder hollow shape, fixed
Groove, groove and 1 endoporus insertion of positioning core axle are offered along axis on 1 tube wall of mandrel of position, in the groove of positioning core axle 1, passes through pin
Axle 2 is hinged with cutter 3, and 3 other end of cutter is fixed with handle 4, and cutter 3 are fixed or be welded on to handle 4 by rivet 5
On；On 1 tube wall of positioning core axle, groove both sides are axially arranged with opening, are easy to cutter 3 to be hinged on positioning core axle 1 by bearing pin 2
In groove；Wherein 3 lower end of cutter is double cutting edges, and two cutting edge spacing are consistent with openings of sizes needed for workpiece.
Its middle groove A/F is more than 3 thickness of cutter, is provided with along groove A/F direction on 1 tube wall of positioning core axle
Pin hole 1b, 3 one end of cutter are provided with and are hinged through hole 3a, and bearing pin 2 to be passed through and be hinged pin-and-hole 3a on pin hole 1b and cutter 3, will
Cutter 3 are fixed in groove, and cutter 3 can be rotated around bearing pin 2.
It is described further to structural principle of the present utility model and using step below in conjunction with the accompanying drawings：
During use, driving handle 4 makes cutter 3 rotate to vertical state around bearing pin 2, neonychium to be cut 6 is sleeved on
On apotting spindle 1 is cylindrical, driving handle 4 makes cutter 3 rotate around bearing pin 2, and neonychium is cut by cutter 3 along groove, is cut away
Material fall in the centre bore of apotting spindle 1, punching discharge, then open cutter 3, the neonychium for cutting is removed, this
Apparatus structure is simple, easy to operate, and pipeline protective sleeve otch safeguards simple, low cost without flange, impulse- free robustness.
