Specific embodiment
Refering to shown in Fig. 2-Fig. 4, a kind of bending machine structure, including the straight groove mould 10 set on workbench, on straight groove mould 10
Rectangle and trapezium channel section is offered as semicircular straight trough 11, straight tube blank A to be bending is placed in 11 vallecular cavity of straight trough, the straight trough of straight groove mould 10
11 one end is disposed with circular arc mould 20, there is the rectangle and trapezium channel section along wheel rim circumferentially in the generally runner shape of circular arc mould 20 and wheel rim
For semicircular arc groove 21, the circular arc mould 20 includes two halfbodies of axial direction, and mandrel 26 is axial along circular arc mould 20
It is passed through afterwards in the centre bore opened up and passes through nut and upper and lower two halfbodies of circular arc mould 20 are axially connected, upper and lower two halfbodies
On the axial end face being bonded to each other on a setting it is fluted 24, another be provided with protrusion 25, groove 24 blocks with protrusion 25
Connect the limiting cooperation for forming circumferencial direction.Bend pipe after molding is bent in order to facilitate taking-up, circular arc mould 20 is designed to by upper and lower
Two halfbodies are formed, and when needing to bend bend pipe, two halfbodies of circular arc mould 20 are axially connected with nut, when needing to take out bend pipe
During finished product, turn nut and open two halfbodies of circular arc mould 20, upper and lower two halfbodies are when by being separated from each other trend, groove
24 and raised 25 side wall avoids the possibility of the two separation, so as to ensure that the complete and shape of groove profile to generating resistance each other
The entirety of shape and first and second two sections short straight trough 22,23 is straight, and conjunction slot direction is consistent, reduces the shearing force of mandrel 26, ensures
Bending quality.
As the preferred embodiment of the utility model, it is in ten that groove 24, which is arranged on upper semi-body and on the lower face of upper semi-body,
Font arranges that protrusion 25 is arranged on lower semi-body and is arranged on the upper surface of lower semi-body in cross.Utilize this cross
Moulding arranged crosswise further improves the connection resistance between upper and lower two plate halfbodies, makes the two after being pre-tightened with nut
Inconsistent phenomenon will not occur again, bending quality is good.
Further, the section of groove 24 and protrusion 25 is trapezoidal.
The mandrel 26 of the circular arc mould 20 is arranged for vertical direction and mandrel 26 is fixed relative to operating position, drives
Mechanism driving circular arc mould 20 is rotated around the shaft core of its mandrel 26, and first and second two sections short straight trough 22,23 is additionally provided on circular arc mould 20,
Between first and second two sections short straight trough 22, the 23 and each other smooth arrangement that postpones of arc groove 21, there is straight trough in the side of gripping block 30
Section 31 engages one end tube body for clamping straight tube blank A to be bending with the on circular arc mould 20 first short straight trough 22, and driving mechanism is driven
The 11 notch face of straight trough and relative rolling of dynamic circular arc mould 20 and straight groove mould 10 coordinate, and gripping block 30 is servo-actuated and keeps thereon straight
Slot section 31 clamps one end tube body of straight tube blank A to be bending with the first short straight trough 22 on circular arc mould 20, and driving mechanism driving is straight
Channel mould 10 and 20 relative rolling of circular arc mould to straight trough 11 and the short 23 notch face of straight trough of second segment and clamp straight tube blank A to be bending
Other end tube body.Driving mechanism driving gripping block 30 engages to clamp straight tube blank A's to be bending with the first short straight trough 22
One end tube body, then driving mechanism driving circular arc mould 20 and 11 notch face of straight trough and the relative rolling cooperation of straight groove mould 10 are used for
Scheduled radian is bent, due to circular arc mould 20 and extruding of the straight groove mould 10 to straight tube blank material A to be bending so that bend the curved of forming
Pipe curved arc section tail end occur on the inside of convex bulging phenomenon, at this moment the 23 notch face of straight trough short with second segment of straight trough 11 and clamping it is to be curved
Drum convex on the inside of the tail end of curved arc section is effectively subject to shaping, convex drum is made uniformly to disperse by the other end tube body of straight tube blank A processed
On straight pipe after to the tail end of curved arc section, product quality is improved.
The leading portion tube body of straight tube blank A to be bending occurs to slide or rotate, gripping block 30 during bending in order to prevent
Straight slot 31 vallecular cavity inner wall be rough surface.Rough surface can both increase between the leading portion tube body of straight tube blank A to be bending
Frictional force, prevent it from moving, and the pipe shaft of leading portion tube body will not be damaged.
