Bolt assembly 50, locating rack 32 is moved to the correct position on locating slot 311, then uses bolt assembly 50 fixing again.
And gripper shoe 323 is arranged on installing plate 322 and perpendicular to installing plate 322, plays a supportive role to pushing assembly 33, in order to push
Assembly 33, location hole 321 is arranged in gripper shoe 323, it is only necessary to be fixed on the support bar 331 pushing assembly 33 during installation
In location hole 321, simple and fast.Certainly, in other embodiments of the invention, locating rack 32 may be arranged as propping up
The form of frame, bearing and pillar, as long as other modes of texturing under the design of the present invention, all in the protection model of the present invention
Within enclosing.
In order to adjust the position relationship pushing between assembly 33 and swan neck system 20, the location hole 321 in this enforcement is waist
Shape hole, this mounting hole extends along perpendicular to the direction of locating slot 311, and with wing nut 40, support bar 331 is fixed on positioning
In hole 321.Using the present embodiment during pushing assembly 33, can move back and forth along the length direction of location hole 321 and prop up
Strut 331, then being fixed with wing nut can be it is seen then that according to the present embodiment, be easy to be adjusted to pushing assembly 33 suitably
Position.
Referring to reference to shown in Fig. 1 and Fig. 3, the swan neck system 20 in the present embodiment include circle mould 21, pattern 23, handle 22 with
And clamping 24, during bend pipe, adjustment support bar 331 is so as to be located at correct position at reducing.Fixed length pipe fitting after blanking is inserted in and props up
Strut 331 simultaneously continues to push away near locating rack 32 to arriving to the second positioning sleeve 332b near locating rack 32, spring contraction, Zhi Dao
Two positioning sleeve 332b slide at the reducing of support bar 331.Now because the external diameter that support bar 331 is relatively large in diameter section is more than second
The internal diameter in the set hole of positioning sleeve 332b, the second positioning sleeve 332b stops sliding and realizes positioning, and now spring stops shrinking and having
Certain screen resilience.And one end of the close swan neck system 20 of support bar 331 is located at the straightway point of contact of circle mould 21 and pattern 23
Place.Clamping 24 is clamped pipe fitting (caliber no more than ∮ 6 bronze medal to the movement of circle mould 21 direction by the handle 22 then holding manual tube bender
Pipe can not use pattern), rotary handle 22 drives clamping 24 by pipe fitting bending to set angle, then unclamps clamping 24.Place
Pipe fitting after bending is ejected in the body feed tank below manual tube bender by the recoil of spring in contraction state, and then spring is extensive
Multiple nature.
In sum, the present invention is that it is right to realize in bend pipe by the effect using support bar 331 and delivery device 332
The positioning of pipe fitting and the automatic blanking bending rear tubular member, thus optimizing bend pipe action, improve production efficiency, and utilize support bar
331 improve pipe fitting bending part cockle.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
