Embodiment
In the following, with reference to the drawings and specific embodiments, the invention will be further described：
Referring to shown in Fig. 1-5, for a kind of local bulging device of pipe fitting of the present invention, it is used in the inside of metal tube to pipe
The tube wall of part is extruded, and makes the tube wall of pipe fitting by deforming upon outside interior, thus increase the inner space of pipe fitting part with
The suitable part of inside pipe fitting installation makes outer surface of pipe fittings form the structure that adaptation pipe fitting itself is installed, such as shown in Fig. 1-5
Bulging device, its can be used for semi-trailer support column local bulging, to meet that the transmission mechanism of supporting leg being capable of whole or portion
Point in the inner cavity of pipe fitting.
Referring to Fig. 3, the local bulging device of above-mentioned pipe fitting includes cavity plate component 30, punch assemblies 20 and drive component,
Wherein, cavity plate component 30 includes two cavity plate units 31, which is oppositely arranged, and each cavity plate unit
On be both provided with a recess 311, the recess 311 on two cavity plate units 31 is arranged on face opposite both it, two cavity plate lists
Two recess in member 31 surround a die cavity jointly, and the shape of the die cavity is consistent with the shape after 90 bulging of pipe fitting, that is,
Say, for pipe fitting 90 after by the processing of the bulging device of the present invention, its outer surface forms the shape consistent with die cavity inner surface, i.e., recessed
The shape of position 311 is configured according to the processing request of pipe fitting 90, is not repeated herein.Punch assemblies 20 include 22 He of core rod
Multiple cores 23, multiple cores 23 are disposed around the outside of core rod 22, and core rod 22 and core 23, which are worn, to be connected in die cavity just, i.e. core rod 22
The component formed with the combination of multiple cores 23 is worn and is connected in die cavity, core 23 be located at core rod 22 side and die cavity inner wall it
Between, core rod 22 is column structure, its outer surface at least one end taper portion 221, when core rod 22 moves along its axis, taper portion
The 221 radial outside pushing tow by core 23 towards core rod 22, i.e., when core rod 22 moves axially, by the commutation of taper portion 221,
Core 23 is set diametrically to produce certain displacement, since core 23 and core rod 22 are to wear the mould for being connected on and being made of recess 311
In chamber, after being moved radially outward of 23 core rod 22 of core, the tube wall for the pipe fitting 90 being sleeved on outside core 23 is extruded by core 23,
That is the tube wall of the pipe fitting 90 finally deformation under the action of the Inner extrusion power that core 23 applies, and pass through the shape of die cavity inner surface
Shape, be finally completed the bulging processing of pipe fitting 90.Drive component is used for the axial movement for promoting core rod 22 to postpone core rod 22,
Drive component promotes core rod 22 to move when two cavity plate units 31 mold, and implements bulging to pipe fitting, meanwhile, drive component is complete
When dividing mould into the bulging of pipe fitting and two cavity plate units 31, make 22 counter motion of core rod, in order to which core 23 resets, enable pipe fitting
The demoulding.
The local bulging device of above-mentioned pipe fitting further includes a rack 10, and rack 10 is the installation foundation portion of whole device
Point, punch assemblies 20 further include a template 21, the length direction of the template 21 and rack 10（I.e. illustrate in X to）Vertically, mould
Plate 21 is fixedly mounted in rack 10, and template 21 be provided centrally with one along its thickness direction extend through hole 211, it is columnar
The both ends of core rod 22 are respectively first end and second end, and wherein second end, which is worn, is connected in through hole 211, and above-mentioned multiple cores 23 are equal
It is to be slidably matched with template 21, specifically, being provided with the sliding slot 212 equal with 23 quantity of core in template 21, sliding slot 212 is set
Put in template 21 towards on the side of 22 first end of core rod, one end of multiple cores 23 is correspondingly in sliding slot 212
And the sliding slot 212 that can postpone slides, i.e., when to pipe fitting bulging, guiding is played the role of in radial motion of the sliding slot 212 to core 23；
In addition, on direction of the first end towards second end of core rod 22, the surface of taper portion 221 is gradually inclined towards the center of core rod 22
Tiltedly, that is to say, that for drive component in the first end of pushing tow core rod 22, taper portion 221 is by 23 outside pushing tow of core, drive component
When with moving-mould-core 22 in direction movement of the second end towards first end, then demould pipe fitting 90.
Herein it is emphasized that when core 23 moves radially, the structure that can be oriented to it is not limited only to
The sliding slot 212 stated, can also be and install guide rail between core 23 and template 21, to limit the movement of core 23, or will
Sliding slot is opened on core 23, and the corresponding construction moved into sliding slot is then opened up in template 21, and the guiding as core 23 is carried out with this
Mechanism.
On the basis of such scheme, the present invention also sets multiple mandrils 24, the plurality of mandril 24 and type in template 21
Core 23 corresponds, and the medial extremity top pressure of mandril 24 is gone back between the outer surface of corresponding core 23, mandril 24 and template
Resetting spring is provided with, which is used to apply mandril 24 elastic stress, which is used for mandril 24
All the time towards the middle part pushing tow of template 21, i other words, under the action of the elastic stress, mandril 24 remains one towards mould
The mobile trend in the middle part of plate 21, the core 23 by 24 pushing tow of mandril then made also remain the middle part movement to template 21,
Enable the good outer surface for being fitted in core rod 22 of core 23, to ensure the precision of pipe fitting bulging size, meanwhile, taken off in pipe fitting
After mould, under the elastic stress effect of resetting spring, core 23 can quickly reset, and enable pipe fitting rapidly from core 23
Exterior disengaging.
