A tube expansion component S is equipped with the head of drive shaft 11.Tube expansion component S runs through one second spring bearing 13, should
Tube expansion component S includes the tube expansion valve bar 12, the spring seat slice 15 of 16 and one arc of some reseting leafs of a pair of opposing.This is swollen
The head of pipe valve bar 12 is equipped with a ladder tringle 121, and the afterbody of the tube expansion valve bar 12 is equipped with the rotating cylinder of a semi-circular cylindrical
122 and one annular limited location snap ring 123, the both sides of the edge of the rotating cylinder 122 are respectively equipped with a reset notch 124 and one and slide
Enter inclined-plane 125, the outer wall of the tube expansion valve bar 12 is equipped with the upper spring positioning groove 120 of some arcs, the spring seat slice 15 it is interior
Wall is equipped with the lower spring positioning groove 151 of some arcs, which is separately positioned on this spring positioning groove 120 with
Between spring positioning groove 151.
Wherein, which is between one first operating position and one second operating position, when the tube expansion valve bar
12 when being in the first operating position, which closes up into a cylinder, when the tube expansion valve bar 12 is in the second work
During position, which outwards separates and extrudes the inner wall of copper pipe at the same time.The tube expansion valve bar 12 has magnetism, can be with
Effectively prevent rocking for tube expansion valve bar 12.Hereinafter can the working method of tube expansion valve bar 12 continue to be illustrated.
The working method of the copper pipe tube expander is illustrated below.
As shown in Figures 9 to 11, handle 7 not yet rotates, and the driving of drive shaft 11 protrudes 115 on neutral position,
At this time, driving prominent 115 is protruded slips into the gap between inclined-plane 125 in a pair.Due to drive disk 114 radius be equal to or
It is slightly less than the radius of the radian of the inner wall of rotating cylinder 122, then, tube expansion valve bar 12 closes up into one under the action of reseting leaf 16
Cylinder or approximate cylinder.
As shown in Figure 12 to Figure 14, the copper pipe for needing tube expansion is inserted into the corresponding rank on ladder tringle 121 by user
On terraced groove, and rotational handle 7.The rotation driving driving worm screw 8 of handle 7, meanwhile, driving worm screw 8 drives driving worm gear 10, driving
Worm gear 10 then drives drive shaft 11 to rotate synchronously.Then, driving prominent 115 starts to extrude slipping into tiltedly in its rotation direction
Face 125, until driving prominent 115 slips into 125 dieback of inclined-plane by this, at this time, which protrudes 115 and is in dieback position.At this time,
A pair of of 12 outside separated in synchronization of tube expansion valve bar and the inner wall for extruding copper pipe at the same time, meanwhile, this is to tube expansion valve bar 12 as driving turns
Axis 11 rotates synchronously, and quickly completes the tube expansion operation of copper pipe joint.After tube expansion is completed, handle 7 is rotated backward, is driven
Prominent 115, which come back to neutral position, sprinkles, and closes up into a cylinder or approximate cylinder again under the action of reseting leaf 16.
It is pointed out that in driving prominent 115 from during neutral position turns to dieback position, it is prominent due to driving
Go out the frictional force between 115 and the inner wall of rotating cylinder 122, tube expansion valve bar 12 can still occurs initially in this with drive shaft 11
Rotate, until driving prominent 115 reaches dieback position.Once driving prominent 115 reaches dieback position, tube expansion valve bar 12 is with driving
Turn axis 11 starts to rotate synchronously.
In the rotation process of handle 7, the rotating speed of handle 7 is reduced by driving worm gear 10, and the moment of torsion of drive shaft 11 obtains
Increase substantially, tube expansion speed is fast, efficient.Obviously, driving worm gear 10 is driven to slow down here with driving worm screw 8, profit
It is also feasible, such as gear set or planetary gear set etc. with other slowing-down structures.
It is the operation chart of second of embodiment of the copper pipe tube expander of the present invention, only as shown in Figure 15 to Figure 19
It only show drive shaft 11 and a pair of of tube expansion valve bar 120.Unlike former embodiment, in rotating cylinder 122
A pair of progressive cambered surface 1221 is symmetrically equipped with inner wall, which is in an involute.
As shown in Figure 16 and Figure 17, at this time, the driving protrusion 115 of drive shaft 11, which starts to head into, slips into inclined-plane 125.Work as drive
Turn axis 11 is rotated further, and driving prominent 115 starts to slide against progressive cambered surface 1221 so that a pair of of tube expansion valve bar 12 is progressively
Outside separated in synchronization and the inner wall for extruding copper pipe at the same time, until driving protrudes 115 by progressive 1221 dieback of cambered surface.In tube expansion valve bar
120 it is progressive it is separated during, tube expansion valve bar 120 is also as drive shaft 11 rotates.Once driving prominent 115 reaches
Dieback position, tube expansion valve bar 120 are rotated synchronously with drive shaft 11, quickly complete the tube expansion operation of copper pipe joint.Due to using
The progressive cambered surface 1221 of reducing type, copper pipe expansion good evenness, consistency of thickness are good.
As shown in Figure 20 and Figure 21, it is the third embodiment of copper pipe tube expander of the invention.At this time, in tube expansion valve bar
1200 progressive cambered surface 1221 is equipped with some resistance horizontal stripes 12211, for improve driving prominent 115 and progressive cambered surface 1221 it
Between frictional force.
As shown in Figure 22 and Figure 23, it is the 4th kind of embodiment of copper pipe tube expander of the invention.With the third embodiment party
Formula is not both that some release arc grooves 12212 are equipped with the progressive cambered surface 1221 of tube expansion valve bar 12000, these release arc grooves
12212 arc groove depth is sequentially reduced.
When drive shaft 11 rotates and starts to slide against progressive cambered surface 1221 so that a pair of of tube expansion valve bar 12000 is progressive
The outside separated in synchronization in ground and the inner wall for extruding copper pipe at the same time, until driving protrudes 115 by progressive 1221 dieback of cambered surface.It is prominent in driving
Before going out 115 arrival dieback positions, driving prominent 115 can be sequentially entered in some release arc grooves 12212 so that a pair of of tube expansion valve
Trickle reduction occurs temporarily for the dilation dimension of bar 12000 so that the deformational stress of inflated copper pipe is released and alleviates.
That is, before driving prominent 115 reaches dieback position, the deformational stress of copper pipe obtains multiple release and alleviation, copper pipe
Deformation uniformity be greatly improved, consistency of thickness is good.
Copper pipe tube expander operation facility, no dependence electric power, is adapted to the tube expansion operation of the copper pipe of a variety of calibers, also is adapted for it
The tube expansion operation of his flexible metal conduit.
Not limited to this, any change or replacement expected without creative work, should all cover the guarantor in the present invention
Within the scope of shield.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
