Abstract
A pipe fitting bending technology die can swing along the shape of a deformed workpiece, and comprises two movable arc swing segment lower dies and a fixed center segment lower die; an inner die shape of the center segment lower die has a same radius of curvature with that of a bended pipe; the arc swing segment lower dies can swing around a shaft through a swing shaft platform and an axle center positioning pole fixed on a die body, and can swing along the shape through the arc support between the die body; the fixed center segment lower die is matched with a centering platform arranged on the die body so as to realize die centering process. The three segment dies cooperate so as to bend the pipe fittings, so a flat segment and a bending segment of the bended pipe fitting cannot have shape distortion.
Description
Technical field
The present invention relates to a kind of pipe fitting bending technique mould, it is characterized in that devising one comprises two arc oscillating sections, the syllogic cambered surface support bend pipe bed die of a fixed reference section.Two arc oscillating sections of this mould when carrying out pipe fitting bending technique flow process can along with the change in shape of workpiece automatic adjusting position, thus can guarantee that the every critical size by bending the straight section of pipe fitting and bending section meets the requirements.
Background technology
At present, more common pipe fitting bending process process mould is all generally all-in-one-piece.Processed pipe fitting is placed on the figurate mould of tool, is directly pressed shaping by straightened condition.Period, mold integral fixed, and the change of relative tertiary location can not occur because of the relation of compacting load.But because the wall thickness of processed pipe fitting and length can not be mated completely with mould, therefore when using integral formula mould bends pipe fitting be very easy to occur workpiece flat segments abnormal deformation or bending section curvature overproof, the situation of mouth of pipe section excurvation is also there will be time serious, thus cause whole pipe fitting to be scrapped, cause damage.Therefore, in order to guarantee that in bending process process the shape of pipe fitting flat segments and bending section distortion can not occur, reasonability and the validity of process mould design are very important factors.
Summary of the invention
Bending in process shape distortion can not occur in order to ensure processed pipe fitting, the present invention proposes a kind of syllogic cambered surface support bend pipe bed die.This mould is that two flat segments of processed pipe fitting and bending section are provided with corresponding die unit respectively, wherein bending section counterdie has the internal mold shape of the same radius of curvature the same by bend pipe, to be fixed on die ontology and to keep centering, to guarantee that the curvature of workpiece bows section meets the requirements and keeps symmetrical; Two flat segments bed dies can bend the change in shape automatic adjusting position along with workpiece in process, thus can guarantee that workpiece flat segments abnormal deformation can not occur.
The object of the present invention is achieved like this: a kind of pipe fitting bending process process mould, is provided with swingable mould sections and fixed reference mould sections.Wherein fixed reference mould sections has the internal mold shape of the same radius of curvature the same by bend pipe, and this section die remains that centering is to guarantee the shape of part curvature section, swings mould sections conformal in process and swings with the shape guaranteeing workpiece flat segments.This mould structure comprises arc oscillating section counterdie, pole, location, axle center, swings pillow block, die ontology, supports cambered surface, interlude counterdie and centering boss.Wherein, the groove bottom interlude counterdie matches to realize centering with the centering boss be arranged on die ontology; The center of arc oscillating section counterdie cambered surface part is connected with swing pillow block, matches with swing pillow block and be fixed by bolts on die ontology in pole, location, axle center; Some cambered surface boss of arc oscillating section counterdie (cambered surface projected area is larger), and match to realize cambered surface support with the cambered surface groove (cambered surface projected area is less) be arranged on die ontology; When carrying out pipe fitting and bending, bent workpiece and be placed in a straightened condition on mould, now workpiece is supported by two sections of arc oscillating bed dies, and mould keeps level.After starting loading; workpiece starts to occur bending and deformation; two sections of arc oscillating bed dies are while providing support for workpiece; due to the existence that cambered surface supports; can make it that conformal occurs along with the flexural deformation of workpiece to swing; pole, location, axle center can guarantee that cambered surface remains around axis swing, until the process that bends terminates.Workpiece to be machined can obtain enough support forces all the time in this process, thus ensure that workpiece flat segments distorting transformation can not occur.Interlude counterdie has the internal mold shape of the same radius of curvature the same by bend pipe and remains centering, and its object is exactly the symmetry accurately meeting shape need and bending section in order to ensure pipe fitting bending section.
The present invention compared to existing technology tool has the following advantages: the conformal of arc oscillating section swings the risk eliminating workpiece flat segments generation abnormal deformation; Cambered surface supports and can for by the support force bending workpiece and provide enough large, and can be used for bending heavy caliber thick wall pipe fitting; Interlude counterdie, by the centering characteristic utilizing centering boss can guarantee fixed reference mould all the time, drastically increases the success rate that pipe fitting bends.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.
See Fig. 1, a kind of pipe fitting bending process process mould, is provided with swingable mould sections and fixed reference mould sections.This mould structure comprises and is bent workpiece 1, arc oscillating section counterdie 2, pole, location, axle center 3, swings pillow block 4, die ontology 5, supports cambered surface 6, interlude counterdie 7 and centering boss 8.Wherein, interlude counterdie 2 has the internal mold shape of the same radius of curvature the same by bend pipe, and the groove bottom it matches with the centering boss 8 be arranged on die ontology 5; The center of two arc oscillating section counterdie 2 cambered surface parts is connected with two swing pillow blocks 4 respectively, and pole, location, two axle center 3 merging that matches with corresponding swing pillow block 4 is respectively fixed by bolts on die ontology 5; Some cambered surface boss of arc oscillating section counterdie 2 (cambered surface projected area is larger), and match to form support cambered surface 6 with the cambered surface groove (cambered surface projected area is less) be arranged on die ontology 5.
When carrying out pipe fitting and bending, bent workpiece 1 and be placed in a straightened condition on mould, now workpiece keeps the arc oscillating bed die 2 of level to support by two sections.After starting loading; bent workpiece 1 to start to occur bending and deformation; two sections of arc oscillating bed dies 2 are for being bent while workpiece 1 provides support; owing to supporting the existence of cambered surface 6; it can be made to swing along be there is conformal by bending the flexural deformation of workpiece 1; pole, location, axle center 3 guarantee cambered surface remain around swing pillow block 4 swing, until the process that bends terminates.Interlude counterdie 7 has with being remained centering by the internal mold shape of radius of curvature that bends workpiece 1, its objective is the symmetry accurately meeting shape need and bending section in order to ensure elbow curvature section.
Structure of the present invention is simple, and process and assemble is convenient, and can by the frock size that changes arbitrarily arc oscillating counterdie and interlude counterdie to adapt to different be bent pipe fitting.Can provide larger support force because cambered surface supports, therefore the program can be applicable to the bending process of heavy caliber thick wall pipe fitting, and can guarantee that bending shaping pipe fitting meets the requirements simultaneously.
