Embodiment one:

Long tubing is cut for difference, it is desirable that the feelings that non-undergauge segment length L1 is unified in Fig. 6 are kept after every root canal material undergauge Condition: where be cased with spring, left front gear cylinder on the left sliding rail 623 between left front gear cylinder mounting block 622 and left support block 624 Mounting blocks 622 can slide on left sliding rail 623, during 502 ejector sleeve material to clamping position of charging ram, tubing front end and stretching position The contact of left front baffle 631 push left front gear cylinder mounting block 622 to move, the rear end of every root canal material is all pushed by charging ram 502 (i.e. tubing keeps the back-end location of every root canal material to unite in the case where cutting long different condition for clamping after the same position of left clamp block 641 One), then left front baffle 631 retreats reset again, and the position that each advance necking of left electro spindle 801 reaches is fixed, therefore can be protected Hold the unification of non-undergauge segment length L1 in Fig. 6.Wherein, the movement of left mechanism with more than, right mechanism is identical.

The sequence of movement of the bilateral reducing device of this short tube are as follows:

A) as shown in Figure 1, charging ram 502 is when left, right follower arm 781 is moved down in the drive of right charging cylinder movable block 7711 It moves to 683 position of pusher groove, tubing is fallen under the effect of gravity in pusher groove 683, and then right follower arm 781 is multiple again Position；

Meanwhile right front cylinder 721 drives right front apron 731 to be pushed forward；

Meanwhile left front gear cylinder 621 drives left front baffle 631 to be pushed forward；

B) charging ram 502 moves to right the position that the tubing in pusher groove 683 is pushed into right clamp block 741, right front apron 731 It plays the role of positioning to tubing；

Meanwhile right ejector beam 412 jacks up a root canal material and drops down onto the groove of right follower arm 781；

Meanwhile left blanking cylinder 601, left clamping cylinder 611 all retract release, the tubing that undergauge finishes is under the effect of gravity It falls, is slipped in blanking box along left feeding plate 661；

C) right clamping cylinder 711 clamps shrinkage waiting open tubing；

Meanwhile left follower arm 681 is mobile, and left hopper inner tube 463 is pushed on pusher groove 683 and is resetted again；

Meanwhile left blanking cylinder 601 is pushed forward；

Meanwhile left front baffle 631 is pushed forward；

D) right front apron 731 resets；

Meanwhile charging ram 502 moves to left the tubing in pusher groove 683 being pushed into left 641 position of clamp block, left front baffle 631 position-limiting actions；

Meanwhile left ejector beam 411 jacks up a left hopper inner tube 461 and drops down onto left 681 groove of follower arm；

E) right electro spindle 901 moves to left carry out necking, then resets；

Meanwhile right follower arm 781 is mobile, tubing in right 781 groove of follower arm is pushed to multiple again in pusher groove 683 Position；

Meanwhile left clamping cylinder 611 clamps shrinkage waiting open tubing；

F) right blanking cylinder 701, right clamping cylinder 711 all retract release, and the tubing that undergauge finishes falls under the effect of gravity It falls, is slipped in blanking box along right feeding plate 761；

Meanwhile right ejector beam 412 jacks up a right hopper inner tube 462 and drops down onto right 781 groove of follower arm；

Meanwhile left front baffle 631 resets；

G) right blanking cylinder 701 is pushed forward；

Meanwhile right front apron 731 is pushed forward；

Meanwhile left electro spindle 801 moves to right carry out necking, then resets；

Above-mentioned six steps of repetitive cycling later: b-g, more movements are performed simultaneously in each step, and six steps complete 2 The necking of root canal material, improves production efficiency.

Embodiment two:

It is the same as example 1 place no longer to repeat, the difference is that the present embodiment is suitable for every root canal after holding undergauge Material undergauge segment length L2 as shown in Figure 7 unified situation.Wherein, before processing, left front gear cylinder mounting block 622 is first adjusted in left cunning It is slid on rail 623 behind appropriate location using screw locking, fixed left front gear cylinder mounting block 622 is opposite with left sliding rail 623 Position, when the process of 502 ejector sleeve material of charging ram to clamping position, the front end of tubing is contacted with the left front baffle 631 of stretching, due to Left front 631 position of baffle has been locked and can not push, so that the front position of every root canal material is unified, then clamps again (i.e. tubing keeps the front position of every root canal material unified in the case where cutting long different condition), then left front baffle 631 retracts multiple again Position can keep the system of undergauge segment length L2 in Fig. 7 since the position that each advance necking of left electro spindle 801 reaches is fixed One.Wherein, the movement of left mechanism with more than, right mechanism is identical, and details are not described herein.

Above-mentioned reducing device can be according to the pusher groove 683 and folder of the cross sectional shape setting respective cross-section shape of processing tubing The clamping slot of tight block, for processing the tubing of square pipe or other odd-shaped cross sections.

The above embodiments of the present invention is merely examples for clearly illustrating the present invention, and is not Limitations of the embodiments of the present invention.For those of ordinary skill in the art, on above explained basis On can also make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc., should be included in this reality Within novel scope of protection of the claims.
