Surely there is bend wheel mould；Head sprocket is connected with driving mechanism, and under the action of driving mechanism, head sprocket can drive main shaft to revolve
Turn, so that bend wheel mould rotates.
Above-mentioned mainshaft mechanism has the following disadvantages：First, key connection is passed through between main shaft and head sprocket so that the torsion of main shaft
The power limit is relatively low, so as to produce the problem of two necks that main shaft is located above and below head sprocket are easily broken；2nd, bend wheel mould
It is sheathed on the outside of main shaft upper end so that main shaft upper end easily fractures.
The content of the invention
The technical problem of solution is needed for of the invention：The main shaft torsion limit can be obviously improved by providing one kind, reduced main shaft and broken
Split the mainshaft mechanism in the bending machine of risk.
To solve the above problems, the technical solution adopted by the present invention is：Rack, expansion bearing has main shaft, main shaft in rack
Upper end is fixed with bend wheel mould, and main shaft is equipped with head sprocket, and main shaft is integral type machine-shaping, head sprocket and driving with head sprocket
Device is connected, and under the action of driving device, head sprocket drives main shaft rotation, so as to drive bend wheel mould to rotate, main shaft with
Head sprocket is integral type machine-shaping；The main shaft is connected between rack by a pair of of taper roll bearing；The pipe bending wheel
Specific mounting structure between mould and main shaft is：Main shaft upper end is provided with some threaded mounting holes, bolt runs through from top to bottom
Tightened after bend wheel mould in threaded mounting hole, so that bend wheel mould is fixedly mounted on main shaft upper surface.
Further, the mainshaft mechanism in foregoing bending machine, wherein：The main shaft is connected with angle measuring mechanism,
Angle measuring mechanism can measure Spindle rotation angle degree, and when main shaft is rotated to predetermined angular, angle measuring mechanism can pass through
Controller closes driving device.
Further, the mainshaft mechanism in foregoing bending machine, wherein：The concrete structure bag of the angle measuring mechanism
Include：The primary shaft belt pulley of main shaft bottom and the encoder being fixedly installed in rack are fixedly installed in, is consolidated on the output shaft of encoder
Surely encoder belt wheel is arranged with, is connected between encoder belt wheel and primary shaft belt pulley by rack belt, encoder and controller
It is connected.
The beneficial effects of the invention are as follows：First, main shaft and head sprocket are integral type machine-shaping, and main shaft can be substantially improved
The torsion limit, significantly reduces the risk that main shaft is broken；The 2nd, bend wheel mould is fixed on to the upper end of main shaft by bolt
On face, bend wheel mould is socketed on the connection structure outside main shaft by substitution tradition, so as to reduce cutting between bend wheel mould and main shaft
Shear force, significantly reduces the risk that main shaft top is broken off；3rd, the anglec of rotation of main shaft can be accurately controlled using encoder
Degree, so as to lift bending quality.
Brief description of the drawings
Fig. 1 is the structure diagram of the mainshaft mechanism in bending machine of the present invention.
Embodiment
Below in conjunction with the accompanying drawings and preferred embodiment is described in further detail technical solutions according to the invention.
As shown in Figure 1, the mainshaft mechanism in bending machine, including：Rack 1, expansion bearing has main shaft 2, main shaft 2 in rack 1
Upper end is fixed with bend wheel mould 5, and main shaft 2 is equipped with head sprocket 4, and main shaft 2 and head sprocket 4 are integral type machine-shaping, so just
The torsion limit of main shaft 2 can be greatly promoted, significantly reduces the risk that main shaft 2 is broken.The head sprocket 4 is filled with driving
Put and be connected, under the action of driving device, head sprocket 4 drives main shaft 2 to rotate, so that drive bend wheel mould 5 to rotate, main shaft 2
It is connected between rack 1 by a pair of of taper roll bearing 6, for taper roll bearing 6 compares plain bearing, can be significantly carried
Rise the torsion limit of main shaft 2.In the present embodiment, the specific mounting structure between the bend wheel mould 5 and main shaft 2 is：In master
2 upper end of axis is provided with some threaded mounting holes, and bolt 7 is screwed into threaded mounting hole after running through bend wheel mould 5 from top to bottom, so that
Bend wheel mould 5 is fixedly mounted on the upper surface of main shaft 2.In this way, the upper surface by the way that bend wheel mould 5 to be fixed on to main shaft 2
On, substitute traditional structure being socketed on using bend wheel mould 5 outside main shaft 2, so as to reduce between bend wheel mould 5 and main shaft 2
Shearing force, significantly reduces the risk that 2 top of main shaft is broken off.In the present embodiment, the main shaft 2 and angle measuring mechanism
