Description
Technical field
The present invention relates to pipe fitting processing technique field, relate in particular to a kind of pipe fitting bending apparatus.
Background technology
Pipe fitting bending molding process is widely used in the manufacturing industry such as automobile, boats and ships, aircraft, food machinery, chemical industry equipment, if vehicle turbine pressure inlet is just by tube bending moulding.In machining Practice, it is very short that vehicle turbine pressure inlet has straightway between two bent angles and two bent angles, in the time steel pipe being carried out to minor radius bending, very easily cause the gross distortion of brake forming, cause steel pipe inner side significantly wrinkling, obviously flatten along flexural center in outside, the center of circle of its cross sectional shape before by bending becomes the pancake after bending, and sectional area also significantly shrinks.This not only causes appearance quality, and can affect service property (quality).
Summary of the invention
In order to solve the technical problem existing in background technology, the present invention proposes a kind of pipe fitting bending apparatus, realize the bending operation of pipe fitting, it is simple in structure, and after pipe fitting bending, interior outside is smooth, smooth.
A kind of pipe fitting bending apparatus that the present invention proposes, comprise actuating unit, workbench, bending die, the first plug, the second plug, clamping, pressing mold, profiling clamping, profiling pressing mold, described actuating unit drives and is connected with described bending die, described bending die is positioned at described workbench one side, described profiling clamping, described profiling pressing mold is positioned at described workbench upper strata, described clamping, described pressing mold is positioned at the lower floor of described workbench, described bending die is positioned at the outside of pipe fitting to be bent, one side of bending die is provided with anti-wrinkling mould, described anti-wrinkling mould is positioned at the outside of described pipe fitting to be bent, described pipe fitting to be bent and described anti-wrinkling mould insert the first plug in one end of described bending die the same side and the other end inserts the second plug, a side of the first plug is close to described pipe fitting to be bent and inserts by described clamping and described pressing mold, a side of the second plug is close to described pipe fitting to be bent and inserts by described profiling clamping and described direction pressing mold.
Preferably, described the first plug has three hinged movable ball-joints successively, and described the second plug has a movable ball-joint being hinged on barred body, and insert in pipe fitting to be bent one end that described the first plug, described the second plug are provided with movable ball-joint.
Preferably, also comprise auxiliary power mechanism, described auxiliary power mechanism is positioned at described anti-wrinkling mould one side, and provides augmented thrust to described the first plug.
In the present invention, clamping, pressing mold and profiling clamping, profiling pressing mold are divided into upper and lower two-layer setting, the first plug, the second plug insert respectively pipe fitting to be bent two ends, pipe fitting to be bent carries out levels punching bending, whole BENDING PROCESS is divided into two steps carries out, owing to adopting punching bending, can prevent that the inner side of pipe fitting to be bent is significantly wrinkling, and can improve the flat ratio after bending; By anti-wrinkling mould is set, can effectively improve pipe fitting to be bent wrinkling at BENDING PROCESS ectomesoderm, improve bending machining quality, thereby realize the high flat ratio bending of pipe fitting minor radius.
