Description

A kind of forward and reverse angle pipe equipment

Technical field

The utility model relates to bending machine apparatus field more particularly to a kind of forward and reverse angle pipe equipments.

Background technique

With the development of tubular object extruding industry, pipe shape is increasingly sophisticated, this undoubtedly also proposes tubular object extruding machinery Requirements at the higher level, either to the thickness of pipe, length, bending degree, or the requirement to bend pipe shape is all more and more diversified, So corresponding equipment is also just continuously updated and is transformed, could only in this way be played for the development of social all trades and professions and demand The effect of auxiliary.Bending machine is one of the general and required product that is of wide application.

The structure of traditional forward and reverse angle pipe equipment (or being the winding tube apparatus in left and right) includes: headstock, headstock Side is fixed with slideway, and slide with matching is provided on slideway, and the slide is fixed on head, the side of head It is fixed with and holds out against bearing block, hold out against to be provided in bearing block and hold out against bearing, hold out against to be provided in bearing and hold out against screw rod, the top Tight screw rod is parallel with slideway, and the one end for holding out against screw rod is connected with driving device is held out against, and holds out against and is arranged on the other end of screw rod There is feed screw nut with matching, the feed screw nut mutually fixes with headstock；Bend pipe flange is movably set on head Disk, the elbow flange are connected by bend pipe main shaft with bend pipe driving device, and elbow flange top movable is provided with Sliding block, is fixed with two bend pipe axis on sliding block, and two bend pipe axis can be realized alternately and elbow flange by holding out against for head With one heart, wheel model is respectively arranged on two bend pipe axis, the upper end of two bend pipe axis is connected by a pulling plate, solid on headstock Surely there is mold changing locating piece, change the mold and be fixed with guided mode on locating piece, guided mode is internally provided with the hole matched with the pipe of required bending, Midpoint between the center in the hole and two wheel models is corresponding, changes the mold the front end setting of locating piece there are two groove, and two Bend pipe axis is embedded at respectively in two grooves.

The working principle of traditional left and right bend pipe bending machine is:

The pipe of required bending is penetrated in the hole of guided mode, and between the circular arc across the first wheel model and the second wheel model Gap, the contact site of the Guan Shangyu wheel model of required bending are the position of required bending.

When bend pipe counterclockwise, the second bend pipe axis and elbow flange are concentric at this time, and servo motor and speed reducer drive bend pipe Spindle axis counterclockwise rotates by a certain angle, and bend pipe main shaft drives elbow flange to rotate by a certain angle counterclockwise, at this point, the first bend pipe Axis rotates by a certain angle, the second bend pipe axis is counterclockwise counterclockwise under the drive of elbow flange using the second bend pipe axis as the center of circle Rotation certain angle, the active force that pipe between the first wheel model and the second wheel model is counterclockwise by the first wheel model, around second Wheel model is counterclockwise bending certain angle, after completing flexing movement, elbow flange leads under the driving of servo motor and speed reducer Bend pipe spindle drive is crossed, completion rotates clockwise reset.

When equal-diameter elbow clockwise, screw rod can be held out against by holding out against motor driven at this time and rotated clockwise, held out against screw rod and exist After rotating clockwise in feed screw nut, since feed screw nut mutually fixes with headstock, hold out against screw rod rotates clockwise band motivation Head is turned left sliding by the cooperation of slideway and slide along slideway, due to the first bend pipe axis and the lateral lock of the second bend pipe axis and headstock Fixed, the first bend pipe axis and the second bend pipe axis are mutually fixed with sliding block, and head makes sliding block opposite fortune of turning right in head toward left movement It is dynamic, when the first bend pipe axis is concentric with elbow flange, holds out against motor and stop working, so that head stops sliding, servo at this time Motor and speed reducer drive bend pipe main shaft to rotate clockwise certain angle, and bend pipe main shaft drives elbow flange to rotate clockwise one Determine angle, the second bend pipe axis rotates clockwise certain angle under the drive of elbow flange, using the first bend pipe axis as the center of circle, the One bend pipe axis rotation certain angle, the pipe between the first wheel model and the second wheel model is by the second clockwise effect of wheel model Power, around the first wheel model bending certain angle clockwise, after completing flexing movement, elbow flange is in servo motor and speed reducer Driving is lower by bend pipe spindle drive, completes spinning reduction counterclockwise.

The shortcomings that traditional left and right bending machine is: the rebound of bend pipe angle is big, and stability is poor, and has on pipe fitting very deep Load mould.
