Description
Technical field
The utility model is related to the bending apparatus field of rod, section bar or pipe, specially a kind of bend pipe dress for light-wall pipe
Put.
Background technology
At present in construction, commonly used KBG pipe is pre-buried to lay electrical cable.K, B and G are that attaching type connects respectively
Connect, the initial of thin-walled and these three word Chinese phonetic alphabet of steel pipe, KBG pipe adopts the thin-walled of extruded connection interconnection technique zinc-plated
Steel pipe, has many advantages, such as lightweight, low price, easy construction are safe.
But, the wall thickness of KBG pipe is very thin, and following table is the parameters of KBG pipe（Unit：mm）：
Because wall is relatively thin, KBG pipe easily occurs in bending to rupture and scraps, and affects construction speed, and waste of manpower
Material resources.
Utility model content
In order to overcome the defect of prior art, a kind of structure is provided to be simple and convenient to operate, strong adaptability, high yield rate
Pipe bending equipment, the utility model discloses a kind of swan neck system for light-wall pipe.
The utility model reaches goal of the invention by following technical solution：
A kind of swan neck system for light-wall pipe, including base and support, support is fixed on base, it is characterized in that：Also
Put including being sent into pulley, transmission gear, wheel shaft and fan,
The external diameter being sent into pulley is more than transmission gear external diameter, may be used after being sent into pulley and the concentric connection of transmission gear wheel shaft again
It is rotatably arranged on base；
Fan pendulum is rotatably arranged in cradle top by bearing pin, and the arc-shaped edges of fan pendulum, towards base, are fanned on the arc-shaped edges of pendulum
It is provided with the tube seat that cross section is circular arc, at the outer rim of fan pendulum arc-shaped edges, is provided with fan pendulum tooth, the inner of assister bar is fixed on fan pendulum
Circle centre position；
The cross section of the cross section and tube seat that are sent into pulley race pieces together circular hole, and the gear teeth of transmission gear and fan pendulum tooth are mutual
It is meshed.
The described swan neck system for light-wall pipe, is characterized in that：The external diameter being sent into pulley is the 1.2 of transmission gear external diameter
～2 times；The central angle of fan pendulum is 60 °～120 °.
When the utility model uses, first assister bar is placed in side, KBG pipe to be curved is penetrated from opposite side and is slided by feeding
In the circular hole that the cross section of the cross section of wheel race and tube seat pieces together, then hold assister bar and slowly rotate to opposite side, fan
Pendulum makes tube seat and feeding pulley rotate in opposite directions by the engagement of fan pendulum tooth and transmission gear, and the external diameter due to being sent into pulley is more than
The external diameter of transmission gear, when both rotate equal angular, the rotation distance being sent in pulley outer rim is more than transmission gear outer rim
On rotation distance be more than, thus promote KBG manage, KBG pipe gradually send into, and make KBG pipe fit tube seat bending.In bend pipe
During, with the feeding pulley propulsion KBG pipe in base, make KBG pipe uniform force in BENDING PROCESS, and crooked position is able to
It is continually changing, force dispersion is opened, thus greatly reducing, the KBG leading to because of unbalance stress is tubular to be become excessive and ruptures,
Reduce the waste of material and labour, construction is lighter, more can not be damaged so that threading is normal by cable in effective protection pipe,
The utility model is applicable to the buckling work that various pipelines especially wall thickness is less than the light-wall pipe of 2mm.
The beneficial effects of the utility model are：Structure is simple, easy to operate, strong adaptability, high yield rate.
Brief description
Fig. 1 is front view of the present utility model；
Fig. 2 is left view of the present utility model.
Specific embodiment
Further illustrate the utility model below by way of specific embodiment.
Embodiment 1
A kind of swan neck system for light-wall pipe, including base 1, support 2, is sent into pulley 3, transmission gear 4, wheel shaft 5 and
Fan pendulum 6, as depicted in figs. 1 and 2, concrete structure is：
Support 2 is fixed on base 1；
The external diameter being sent into pulley 3 is more than transmission gear 4 external diameter, is sent into pulley 3 and transmission gear 4 is connected with one heart with wheel shaft 5
It is rotatably arranged in afterwards on base again；
Fan pendulum 6 is rotatably arranged in support 2 top by bearing pin 61, and the arc-shaped edges of fan pendulum 6 are towards base 1, the circle of fan pendulum 6
Arc side be provided with cross section be circular arc tube seat 62, fan pendulum 6 arc-shaped edges outer rim at be provided with fan pendulum tooth 63, assister bar 64 interior
End is fixed on the circle centre position of fan pendulum 6；
The cross section of the cross section and tube seat 62 that are sent into pulley 3 race pieces together circular hole, the gear teeth of transmission gear 4 and fan pendulum
Tooth 63 intermeshes.
In the present embodiment：The race being sent into pulley 3 is made with rubber, can increasing friction force may be used when being sent into KBG pipe again
Reduce the damage to tube wall, the external diameter being sent into pulley 3 is 1.5 times of transmission gear 4 external diameter；The central angle of fan pendulum 6 is 90 °.
When the present embodiment uses, first assister bar 64 is placed in right side, KBG pipe 10 to be curved is penetrated from right side and is slided by feeding
In the circular hole that the cross section of the cross section and tube seat 62 of taking turns 3 races pieces together, then hold assister bar 64 and slowly rotate to the right,
As shown in the arc arrow a in Fig. 1, fan pendulum 6 makes tube seat 62 by the engagement of fan pendulum tooth 63 and transmission gear 4 and is sent into pulley 3
Opposite rotation, as shown in arc arrow b and c in Fig. 1, the external diameter due to being sent into pulley 3 is more than the external diameter of transmission gear 4, when two
When person rotates equal angular, the rotation distance being sent in pulley 3 outer rim is more than more than the rotation distance in transmission gear 4 outer rim,
Thus promoting KBG pipe 10, KBG pipe 10 is gradually sent into, and so that KBG pipe 10 tube seat 62 of fitting is bent.During bend pipe, with
Feeding pulley 3 propulsion KBG pipe 10 in base 1, makes KBG pipe 10 uniform force in BENDING PROCESS, and crooked position is able to not
Disconnected change, force dispersion is opened, thus greatly reducing KBG pipe 10 deformation leading to because of unbalance stress excessive and rupturing,
Reduce the waste of material and labour, construction is lighter, more cable can not be damaged so that threading is normal in effective protection pipe.
