Abstract
The utility model relates to the high-strength bolt thread rolling mechanisms of thread rolling machine technical field more particularly to a kind of high stability, can be supported to workpiece, moreover it is possible to effectively reduce the frictional force with workpiece.The utility model includes the rolling wheel of two holding spacing and the limited support component for being mounted on lower section in the middle part of two rolling wheels, it is characterized by: the limited support component includes a roller bearing and one group of idler wheel, roller bearing and rolling wheel are arranged in parallel, idler wheel is mounted in the fixing axle below rolling wheel, and the bottom of roller bearing is abutted against at the top of idler wheel, roller bearing is supported.
Description
Technical field
The utility model relates to the high-strength bolt screw-rolling machines of thread rolling machine technical field more particularly to a kind of high stability
Structure.
Background technique
Screw-rolling machine has the identical rolling wheel of a pair of of parameter, is separately mounted on two main shafts of screw-rolling machine, and can pass
Synchronous rotary in the same direction under the driving of motivation structure.Wherein first rolling wheel is driven by oil cylinder carries out radial feed movement, and second
Rolling wheel is overlapped with first rolling wheel in the impression of workpiece surface by adjusting the adjustment of mechanism, rolls out spiral shell in workpiece surface
Line.Workpiece is between two rolling wheels and parallel with the axis of rolling wheel set, and the fixture for adjusting workpiece can be such that workpiece moves axially,
It remains in cold-rolled process and is in freely with two rolling wheels to rolling state.
During rolling externally threaded, workpiece stress can be moved down, therefore had below workpiece and supported equipped with one
Bar limits workpiece and is supported, and support rod and workpiece are arranged in parallel, and surface is wear-resisting alloy material.The structure lacks
Falling into is: the frictional force between the support rod and workpiece is larger, and the tooth top of screw thread can be made burr occur, influences the quality of screw thread, branch
Strut itself is also prone to wear, and service life is not grown, and is needed to be improved.
Utility model content
The purpose of the utility model is to overcome the deficiencies in above-mentioned background technique, provide a kind of high-strength bolt of high stability
Thread rolling mechanism can be supported workpiece, moreover it is possible to effectively reduce the frictional force with workpiece.
The technical purpose of the utility model is achieved in that
A kind of high-strength bolt thread rolling mechanism of high stability keeps the rolling wheel of spacing including two and is mounted on two
The limited support component of lower section in the middle part of rolling wheel, it is characterised in that: the limited support component includes a roller bearing and one group
Idler wheel, roller bearing and rolling wheel are arranged in parallel, and idler wheel is mounted in the fixing axle below rolling wheel, and rolling is abutted against at the top of idler wheel
The bottom of axis, is supported roller bearing.
The roller bearing includes dead axle and the roller that is rotatably installed on dead axle, and the both ends of dead axle are fixed on branch by nut
In the U-shaped opening of frame.
One group of bearing is also equipped in the fixing axle, and bearing is alternatively arranged with idler wheel.
The utility model has the beneficial effect that the utility model is designed using roller bearing, is rolling between workpiece and roller bearing
Dynamic friction can effectively reduce frictional force, avoid workpiece overhauling, and the support of roller bearing also available idler wheel and bearing,
And between idler wheel and bearing and roller bearing also be rolling friction, friction is small, will not deform, and support effect and limit effect are very
It is good.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model.
Fig. 2 is the mounting structure schematic diagram of roller bearing and idler wheel and bearing.
Specific embodiment
With reference to the accompanying drawings of the specification, the utility model is described in further detail.
A kind of high-strength bolt thread rolling mechanism of high stability as shown in Figure 1 and Figure 2 keeps the rolling of spacing including two
Wheel 1 and the limited support component for being mounted on lower section in the middle part of two rolling wheels, the limited support component include a roller bearing with
And one group of idler wheel 4, roller bearing and rolling wheel are arranged in parallel, idler wheel is mounted in the fixing axle 8 below rolling wheel, and the top of idler wheel
The bottom for abutting against roller bearing, is supported roller bearing.
The roller bearing includes dead axle 6 and the roller being rotatably installed on dead axle 3, and the both ends of dead axle are fixed on by nut
In the U-shaped opening 7 of bracket 5.
One group of bearing 9 is also equipped in the fixing axle, and bearing is alternatively arranged with idler wheel, i.e., according to an idler wheel 4, one
9, one, a bearing, 4, one, idler wheel, 9, such forms of idler wheel 4 ... of bearing are arranged.Obviously, the fixed peace of fixing axle
It fills on the bracket and parallel with the dead axle of idler wheel.It when after 2 stress of workpiece to lower pressure, is supported, is rolled by roller bearing
Axis carries out Auxiliary support by idler wheel and bearing, and roller bearing is avoided to deform.
The above is only the preferred embodiment of the present invention, and for those skilled in the art, this is practical new
Type can have various modifications and variations.Within the spirit and principle of the utility model, it is made it is any modification, equally replace
It changes, improve, should be included within the scope of protection of this utility model.
