During for multiple rows of workpiece of different length, as illustrated in fig. 1 and 2, two rows treat that tube expansion workpiece exists discrepancy in elevation Δ h.If as it is shown in figure 1, two rows are when swollen workpiece is upper discrepancy in elevation workpiece, although two row's expander roll height can be unified, but cause expander roll can not simultaneously enter the workpiece mouth of pipe, easily causing workpiece bows to produce and scrap；As shown in Figure 2, if be the lower discrepancy in elevation workpiece, expander roll also to be made and there is the discrepancy in elevation, so the discrepancy in elevation of expander roll is according to depending on the discrepancy in elevation of workpiece and be certain, when changing another only different workpiece of the discrepancy in elevation into, expander roll converts specification again, and the specification causing expander roll is various, be inconvenient to produce in batches, and the replacing of expander roll dismounting is the most very time-consuming arduously.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the drawbacks described above of prior art to provide the tube expanding mechanism of a kind of electric tube expander, and the expander roll height adjustable of this tube expanding mechanism is adapted to the workpiece with the multiple discrepancy in elevation.
This utility model also correspondingly provides a kind of electric tube expander, enables the workpiece for the various different discrepancy in elevation and carries out tube expansion.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is:
Tube expanding mechanism, it includes power seat, support, machine footstock, motor and drive system, ball screw, feed screw nut, expander roll mounting assembly, two groups of expander rolls, two pedestal lower end are arranged on power seat, pedestal upper end fixes machine footstock, ball screw upper end is supported by machine footstock, lower end is by power seat supports, described motor and drive system are arranged on machine footstock, motor is rotated by transmission system drives ball screw, expander roll mounting assembly two end fixes feed screw nut, described feed screw nut is set on outside ball screw, one group of expander roll is arranged in expander roll mounting assembly and through power seat, motor drives two ball screws to rotate by drive system, thus drive feed screw nut and expander roll mounting assembly to move up and down, another group tube expansion is arranged on power seat and parallel with previous group expander roll.
Preferably, above-mentioned power seat arranging expander roll guide plate, expander roll guide plate arranges expander roll guide hole, and expander roll is through the tube expansion region below expander roll guide hole and the entrance of power seat.
Additionally providing the electric tube expander including above-mentioned tube expanding mechanism, it replaces former tube expanding mechanism with this tube expanding mechanism.
This utility model can adjust the difference in height between each group of expander roll due to expander roll mechanism, therefore goes for the many groups of tube expansion workpiece with difference in height, and the tube expansion workpiece for the different discrepancy in elevation can conveniently be adjusted.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As shown in Figure 3,4, tube expanding mechanism, including support 2, machine footstock 3, motor and drive system 4, ball screw 5, feed screw nut 6, expander roll mounting assembly 7.
Above-mentioned two support 2 lower ends are arranged on power seat 1, and machine footstock 3 is fixed in support 2 upper end, and such support 2, power seat 1 and machine footstock 3 form the framework of expanding rod device.
Above-mentioned ball screw 5 upper end is supported by machine footstock 3 by bearing, and lower end is supported by power seat 1 by bearing, and above-mentioned motor and drive system 4 are arranged on machine footstock 3, and motor drives ball screw 5 to rotate by drive system 4.
Above-mentioned expander roll mounting assembly 7 two end fixes feed screw nut 6, and described feed screw nut 6 is set on outside ball screw 5, and expander roll 9 is arranged in expander roll mounting assembly 7 and through power seat 1.Motor drives two ball screws 5 to rotate by drive system, thus drives feed screw nut 6 and expander roll mounting assembly 7 to move up and down, and i.e. drives expander roll to move up and down.
For guiding expander roll 9 to move up and down, power seat 1 arranging expander roll guide plate 8, expander roll guide plate 8 arranges expander roll guide hole, expander roll 9 is through the tube expansion region below expander roll guide hole and power seat 1 entrance.
Another row's expander roll 10 is installed on the power seat 1 of above-mentioned tube expanding mechanism again.
As shown in Figure 4, above-mentioned tube expanding mechanism is installed on existing electric tube expander, obtains adjusting the electric tube expander of expander roll height.
nullWhen expander roll needs to adjust，As shown in Figure 4，First expander roll 9 is adjusted with expander roll 10 lower end in the same horizontal line，Then tube expansion is started，Decline due to power seat 1，Expander roll 9 and 10 liang of row's tube expansions can be driven to decline simultaneously，And simultaneously enter the mouth of pipe of metal tube 11 and 12，Tube expansion can be first completed owing to metal tube 11 is shorter，Now motor and drive system 4 start action，Expander roll 9 is driven to stop after rising a segment distance by ball screw and feed screw nut，Climb minimum Δ h，Power seat 1 may proceed to drive tube expansion 12 to decline until completing the tube expansion action of metal tube 12 simultaneously，Then power seat 1 drives expander roll 9 and 10 to rise with speed again，Expander roll 10 is made to return to initial position，Now motor and drive system 4 start again action，Expander roll 9 is driven to decline identical distance by ball screw and feed screw nut，Make recovering again in the same horizontal line with expander roll 10 lower end of expander roll 9.
The tube expanding mechanism that above-mentioned tube expanding mechanism replaces existing electric tube expander is formed new electric tube expander, see Fig. 5, it includes frame 20, power seat 1, power seat drive mechanism 18, expander roll 9, expander roll 10, power seat 1 and power seat drive mechanism 18 are supported by frame 20, fixing expander roll 10 on power seat 1, power seat drive mechanism drives power seat 1 to move up and down, thus drives expander roll 10 to move up and down, make expander roll enter and leave and treat swollen workpiece, thus complete the workpiece being fixed on below expander roll is carried out tube expansion.During tube expansion, carry out tube expansion along with the decline of power seat drives expander roll to decline.
Owing to other mechanisms of electric tube expander are all identical with existing electric tube expander, therefore it is discussed in detail other mechanisms are the most reinflated.
