For hydraulic cylinder.
Embodiment two:
Difference between the present embodiment and embodiment one is, a kind of structure of profile tooling has been described in detail；Tool
Body as shown in fig. 6, the profile tooling 12 include integrally formed mounting portion 1201 and interconnecting piece 1202, the interconnecting piece
1202 be disc with holes, and the interconnecting piece 1202 is set on the bending axis 8；The mounting portion 1201 is vertical plate
Shape, the one side of the mounting portion 1201 towards the male model 9 are equipped with step, are bolted with loose piece 1203, the work on the step
Block 1203 is adapted with 14 outer profile of profile；It is fixed that bolt is installed on the mounting portion 1201 of 1203 lower section of loose piece
Position block 1204, the bolt locating piece 1204 are equipped with several vertical positioning pins 1205；Pacify at the top of the mounting portion 1201
Equipped with the clamp 13；The mounting portion 1201 is also equipped with support column 1206 far from one end of the interconnecting piece 1202, described
The bottom of support column 1206 is embedded with ball 1207, and the ball 1207 is contacted with the upper surface of the workbench 1.
The difference of the profile tooling of the left and right sides is that the mounting portion height of left side profile tooling is greater than the right profile tooling
Mounting portion height, interconnecting piece is sequentially sleeved on bending axis 8, is equipped with gasket in-between.
Using the profile tooling of this structure, interconnecting piece 1202 can be connected on bending axis 8 and be rotated by axle sleeve, installation
Portion 1201 is capable of fixing profile 14, until profile bending and molding, makes profile uniform force；Basis is convenient in the setting of loose piece 1203
The profile of different model selects different loose pieces, and does not have to replace entire profile tooling 12, increases the use of profile tooling 12
Range, reduces frock cost, and loose piece 1203 can carry out processing customization and replacement according to the cross sectional shape of differential profiles；Positioning
14 position of profile can be accurately positioned in pin 1205, and under the cooperation of clamp 13, the position of profile 14 can accurately be fixed, and improve
The precision of bending；Support column 1206 can support the profile tooling 12 and keep its balance, and ball 1207 is conducive to barman
It is mobile to fill 12.
Further, fixed above each profile tooling 12 to be bolted with a pair of parallel clamp 13, the folder
The collet 1301 of pincers 13 withstands the profile 14.
Embodiment three:
The difference between this embodiment and the first embodiment lies in shape is completed in the bending for describing this mental section automatic bending machine
State, it is specific as shown in fig. 7, male model 9 pushes profile 14 and master mold 10 to move to extreme position, at this time profile 14 in male model 9 and
It is bent under the action of master mold 10, the position for the profile tooling 12 that the locating wheel 15 of the left and right sides limits makes 14 middle part quilt of profile
Bending, and two sides remain intact.
Position block 16 limits 10 further movement of master mold, and triggering travel switch makes power output device 21 stop continuing
Advance；Second spring 20 and the first spring 19 are compressed, and the energy replied has been put aside；In the effect of 21 backhaul of power output device
Lower male model 9 starts to return, and after male model 9 is detached from profile 14, the squeezing action power of profile 14, master mold 10 and profile tooling 12 disappears,
Under the elastic force effect of second spring 20, profile 14 keeps the posture of bending to be returned to together on master mold 10 and profile tooling 12
Initial position unclamps clamp 13, removes profile 14, that is, completes the bending of profile 14.
Due to the presence of the first spring 19, after master mold 10 is replied, the distance between male model 9 and master mold 10 still for initially away from
From；After the profile tooling 12 of two sides is adjusted level, continue bending next time.
Example IV:
The mental section automatic bending machine of the present embodiment is to needing closed product forms to carry out bending, specifically such as Fig. 8
Shown, the profile 14 successively bends four right angles, forms the product forms of frame shape.Profile is when successively bending angle,
The good part of bending will not interfere with this bending machine；And under being loaded of profile tooling 12 and clamp 13, bending is completed
Part will not be deformed, and after the completion of bending, can also integrally be removed in profile tooling 12.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
