Abstract
The utility model belongs to copper pipe processing manufacturing technology field, particularly a kind of copper pipe rolling core bar limit shaft.This copper pipe rolling core bar limit shaft, comprise axis body, axis body left end is connected with core bar, it is characterized in that: described axis body right-hand member round nut is fixed on the first adapter sleeve, taper roll bearing is provided with between axis body and the first adapter sleeve, first adapter sleeve and the second adapter sleeve link together, and the second adapter sleeve and dolly plate link together.The beneficial effects of the utility model are: can prevent limit shaft from rupturing when High Rotation Speed, structure is simple, be convenient to assembling, safe and reliable, improve production efficiency, saved production cost, spacing processing can be carried out to copper pipe fast, ensure that machining accuracy indeformable and higher in copper pipe processing process.
Description
(1) technical field
The utility model belongs to copper pipe processing manufacturing technology field, particularly a kind of copper pipe rolling core bar limit shaft.
(2) background technology
Along with the lasting fast development of China's Air Conditioning Industry, promote the sustainable growth of domestic copper pipe consumption.Copper pipe produce technological process be substantially: pipe continuous casting, cold rolling, annealing, dish draw and finishing.In cold rolling, current three-roll planetary rolling uses comparatively general rolling technique, and the motion of three-roller planetary rolling mill mainly comprises roll around the rotation of own axes, three revolution of roll around pipe axis and the axially-movable of feeding carriage promotion pipe.Meanwhile, need to do spacing process to copper pipe, the accuracy that such guarantee is cold rolling.Traditional limit shaft assembling inconvenience, and very easily rupture when High Rotation Speed, thus cause cold rolling interruption, even can damage copper pipe to be processed, waste raw material, greatly have impact on operating efficiency.
(3) summary of the invention
The utility model in order to make up the deficiencies in the prior art, provide a kind of structure simple, be convenient to assemble, safe and reliable, the copper pipe rolling core bar limit shaft of enhancing productivity, saving production cost.
The utility model is achieved by the following technical solution:
A kind of copper pipe rolling core bar limit shaft, comprise axis body, axis body left end is connected with core bar, it is characterized in that: described axis body right-hand member round nut is fixed on the first adapter sleeve, taper roll bearing is provided with between axis body and the first adapter sleeve, first adapter sleeve and the second adapter sleeve link together, and the second adapter sleeve and dolly plate link together.
The direction of rotation of described axis body is left-handed, and the length of axis body is 706.5mm.
Thrust pad is provided with between described axis body and round nut.
Described taper roll bearing is two, lays respectively at the first adapter sleeve two ends.
Described first adapter sleeve is provided with hexagon socket head cap screw, between hexagon socket head cap screw and the first adapter sleeve, is provided with bullet pad.
The beneficial effects of the utility model are: can prevent limit shaft from rupturing when High Rotation Speed, structure is simple, be convenient to assembling, safe and reliable, improve production efficiency, saved production cost, spacing processing can be carried out to copper pipe fast, ensure that machining accuracy indeformable and higher in copper pipe processing process.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
In figure, 1 axis body, 2 core bars, 3 round nuts, 4 first adapter sleeves, 5 taper roll bearings, 6 second adapter sleeves, 7 thrust pads, 8 hexagon socket head cap screws, 9 bullet pads.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises axis body 1, axis body 1 left end is connected with core bar 2, axis body 1 right-hand member round nut 3 is fixed on the first adapter sleeve 4, taper roll bearing 5 is provided with between axis body 1 and the first adapter sleeve 4, first adapter sleeve 4 and the second adapter sleeve 6 link together, and the second adapter sleeve 6 links together with dolly plate.The direction of rotation of axis body 1 is left-handed, and the length of axis body 1 is 706.5mm.Thrust pad 7 is provided with between axis body 1 and round nut 3.Taper roll bearing 5 is two, lays respectively at the first adapter sleeve 4 two ends.First adapter sleeve 4 is provided with hexagon socket head cap screw 8, between hexagon socket head cap screw 8 and the first adapter sleeve 4, is provided with bullet pad 9.
Adopt a kind of copper pipe rolling core bar limit shaft of the present utility model, axis body 1 driven rotary joint is left-handed, is in use not easy to come off.Axis body 1 is fixed on the first adapter sleeve 4 by two taper roll bearings 5 round nut 3, and swivel joint is connected on axis body 1, and the first adapter sleeve 4 and the second adapter sleeve 6 link together, and the second adapter sleeve 6 and dolly plate link together.Intensity and stationarity increase, and fault rate reduces greatly; Production efficiency is improved.
