Description
Technical field
The present invention relates to a kind of automatic cutting device.More particularly, the present invention relates to the automatic buster of the outer crimping of a kind of polyethylene pipe hot melt banjo fixing butt jointing.
Background technology
Butt fusion welding is one of the most frequently used connected mode of polyethylene pipe, because advantage such as its connection charge is low, welding joint mechanical property is superior and sealing is good is widely adopted in municipal works such as combustion gas conveying, feedwater.Domestic and international many researchers confirm that by quick tension test, long term high temperature hydrostatic test, the test of high-temerature creep tensile fracture, creep tension test etc. crimping is the key factor that influences the hot melt banjo fixing butt jointing life-span.In addition, the fuel gas polyethylene pipeline lay and the course of receiving in, all need outer crimping taken off and make dorsad crooked test to identify the welding situation.
At present, it is hand-powered cutter that used outer crimping is thrown the instrument of removing, and needs firmly it is pressed on the tube wall, and hand rotation connecting rod again simultaneously, is wasted time and energy at complicated operation, and for the excision of outer crimping bottom the pipeline system center tap, operation easier is very big.Its excision quality instability, the crimping that excises inhomogeneous, outer crimping is difficult to by whole excision, uneven phenomenon occurs in that the pipeline outer wall surface is normal, and residual crimping is arranged on joint.According to investigations, manually often need two operator's co-operate in the actual mechanical process of the outer crimping of excision, wasted a large amount of human resources, and the excision quality can not get guaranteeing.At present, do not see that both at home and abroad the development of relevant outer crimping device for excising automatically report is arranged.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, the automatic cutting machine for outer curled edges of polyethylene pipes of the outer crimping of automatic excision pipe fitting welding point that a kind of more convenient and quicker efficiently guarantees the quality is provided.
The present invention is achieved by the following technical solutions: a kind of automatic cutting machine for outer curled edges of polyethylene pipes is provided, comprises cutter, buster has a base automatically, and housing is housed on it; The opening part of base front end is established cutter, and described cutter is a multiple tooth saw blade, by being located at the power transmission shaft that connecting rod slider transmission device in the housing is connected to first motor; Also have one second motor to be connected to angular wheel in the housing by power transmission shaft, the shared turning cylinder of angular wheel and cylindrical straight gear, the two ends of turning cylinder are loaded on the both sides of housing and are parallel to cutter and arrange; The direction recess of a vertical and turning cylinder is established in the below of cylindrical straight gear, and an end of direction recess extends to the cutter place.
As a kind of improvement, the turning cylinder of described cylindrical straight gear is adjustable with respect to the distance of direction recess.
As a kind of improvement, the cutter tooth of described cutter is the twolip tetrahedral structure.
As a kind of improvement, the protection piece is established at described and cutter two ends.
As a kind of improvement, described base is connected by bolt with housing.
As a kind of improvement, two U-shaped fixed mounts are established in described base below.
As a kind of improvement, described base and U type fixed mount flexibly connect by pin.
Beneficial effect of the present invention is:
1, the outer crimping of automatic scraping joint is saved a large amount of manpowers;
2, driven by power, cutting speed is fast, has improved operating efficiency;
3, even impaction state can be regulated and keep to fixture, significantly improved the excision quality of crimping.
Compared with prior art, no matter be from operating aspect, still remove the quality aspect from crimping, the present invention has significant advantage than existing scraper.

The specific embodiment
With reference to the accompanying drawings, will describe the present invention below.
Automatic cutting machine for outer curled edges of polyethylene pipes in the present embodiment has a base 1, and housing 2 is housed on it, and base 1 and housing 2 are connected by bolt, to realize the compatible universal of agent structure of the present invention in the different series pipe applications.Two U-shaped fixed mounts 12 are established in base 1 below, flexibly connect body fixing on tubing in the handled easily process by pin 13.
The opening part of base 2 front ends is established cutter 3, cutter 3 is multiple tooth saw blades, by being located at the power transmission shaft that housing 2 interior connecting rod slider transmission devices 4 are connected to first motor 5, connecting rod slider transmission device 4 is converted into rotatablely moving of first motor 5 the reciprocal cutting movement of cutter 3.
Also have one second motor 6 to be connected to angular wheel 7 in the housing 2 by power transmission shaft, angular wheel 7 and cylindrical straight gear 8 shared turning cylinders 9, the two ends of turning cylinder 9 are loaded on the both sides of housing 2 and are parallel to cutter 3 and arrange; Angular wheel 7 carries out vertical transmission with rotatablely moving of second motor 6, realizes rotatablely moving of cylindrical straight gear 8.
The direction recess 10 of a vertical and turning cylinder is established in the below of cylindrical straight gear 8, and an end of direction recess 10 extends to cutter 3 places.The turning cylinder of cylindrical straight gear 8 is adjustable with respect to the distance of direction recess 10.
The cutter tooth of cutter 3 is the twolip tetrahedral structure, and protection piece 11 is established at its two ends.
For further specifying structure of the present invention, it is as follows now will to use the outer crimping excision of plastic conduit of the present invention process prescription:
Outside the excision plastic conduit during crimping, at first, be that first motor 5 is started, utilize the outer crimping of cutter 3 cutting pipelines, be closely attached on the pipeline outer wall face fully up to cutter 3, cutter 3 two ends have protection piece 11, to prevent scratch pipeline outer wall face (shown in Fig. 5,6,7), then U type fixed mount 12 is connected by pin 13 with base 1, realizes the fixing of body and pipeline;
Touch housing 2 then machine is moved along tube wall, be imported into direction recess 10 up to cut outer crimping.After this, utilize the outer crimping of rotation drive of cylindrical straight gear 8 in direction recess 10, to move, thereby realize the automatic rotation of body around pipeline outer wall;
At last, after outer crimping had cut, outer crimping was taken out in the body motion of just stopping the rotation automatically behind the closing machine power supply, with pin 13 taking-ups, unloaded U type fixed mount 12, took off body.So far, the excision operation of the outer crimping of pipeline is just finished.
It is also to be noted that what more than enumerate only is specific embodiments of the invention.Obviously, the invention is not restricted to above embodiment, many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
