Pipe fitting is part pipe being connected into pipe fitting, after pipe fitting machines, often needs to carry out bending operation to pipe fitting.In prior art, to wrap direction equipment bending and the manpower bending nothing more than of pipe fitting.Equipment bending, apparatus for bending structure is mostly comparatively complicated, can not accomplish good control to the bending angle of pipe fitting; Manpower bending, bending efficiency is low, wastes time and energy, and bending angle can not ensure, is not suitable for modern production.The problems referred to above need solution badly.
Summary of the invention
For solving the technical problem existed in background technology, it is high that the present invention proposes a kind of bending efficiency, the pipe fitting apparatus for bending that bending angle is controlled.
A kind of pipe fitting apparatus for bending that the present invention proposes, comprising: base, installing rack, die, punch, drive unit, the first fixture and the second fixture;
Die comprises the first die, the second die, first die and the second die are oppositely arranged and are rotationally connected base respectively, the bending space being used for bending pipe fitting is formed between first die and the second die, first die and the second die offer the first die pipe fitting trough and the second die pipe fitting trough along its length respectively, the first fixture for clamping position tubular first end is slidably mounted in the first die pipe fitting trough, and the second fixture for clamping position pipe fitting second end is slidably mounted in the second die pipe fitting trough;
Installing rack is arranged on base, and drive unit is arranged on installing rack, and drive unit drives the punch connecting and be positioned at above bending space, and punch can be proceeded in described bending space.
Preferably, punch has triangular-section, punch near turning, die side rounding off, near one end, bending space to away from the extreme direction of bending space one, punch sectional area increases gradually.
Preferably, two other corner's rounding off of punch.
Preferably, the first die pipe fitting trough, the second die pipe fitting trough run through the first die, the second die respectively.
The pipe fitting apparatus for bending that the present invention proposes, admittedly pipe fitting two ends are gripped respectively by the first fixture and the second fixture, drive unit drives punch descending, punch enters in the bending space that surrounded by the first die and the second die, and pressure is applied to pipe fitting, make the first fixture and the second fixture slide and drive pipe fitting to move downward, pipe fitting is moving downward in process by bending.Due to the adjustable angle of the first die and the second die respect thereto, pipe fitting bending angle can be controlled by the displacement controlling punch descending.The pipe fitting apparatus for bending that the present invention proposes, can realize the bending operation to pipe fitting, and the bending angle of pipe fitting is controlled, bending efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of pipe fitting apparatus for bending that the present invention proposes.
Detailed description of the invention
As shown in Figure 1, Fig. 1 is the structural representation of a kind of pipe fitting apparatus for bending that the present invention proposes.
With reference to Fig. 1, the present invention proposes a kind of pipe fitting apparatus for bending, comprising: base 1, installing rack 2, die 3, punch 4, drive unit 5, first fixture and the second fixture;
Die 3 comprises the first die 31, second die 32, first die 31 and the second die 32 are oppositely arranged and are rotationally connected base 1 respectively, the bending space being used for bending pipe fitting is formed between first die 31 and the second die 32, first die 31 and the second die 32 offer the first die pipe fitting trough 311 and the second die pipe fitting trough 321 along its length respectively, the first fixture for clamping position tubular first end is slidably mounted in the first die pipe fitting trough 311, the second fixture for clamping position pipe fitting second end is slidably mounted in the second die pipe fitting trough 321,
Installing rack 2 is arranged on base 1, and drive unit 5 is arranged on installing rack 2, and drive unit 5 drives the punch 4 connecting and be positioned at above bending space, and punch 4 can be proceeded in described bending space.
In such scheme, pipe fitting two ends are gripped respectively by the first fixture and the second fixture, adjust the angle of the first die 31 and the second die 32 respect thereto 1, drive punch 4 descending by drive unit 5, punch enters in the bending space that surrounded by the first die 31 and the second die 32, and pressure is applied to pipe fitting, the first fixture and the second fixture is made to slide and drive pipe fitting to move downward, pipe fitting is moving downward in process by bending, the descending end of punch 4, pipe fitting motion stops, and pipe fitting bending terminates.
Punch 4 has triangular-section, punch 4 near turning, die 3 side rounding off, from away from one end, bending space by near bending space one extreme direction, punch 4 sectional area increases gradually, and the design of this structure makes pipe fitting not easy damaged in Forging Process.Further, two other corner's rounding off of punch 4, effectively reduces the friction of punch 4 in descending process and between die 3.
To in pipe fitting Forging Process, punch 4 pairs of pipe fittings apply pressure, and pipe fitting is stressed and abut with die 3, makes pipe fitting easily deformation occur.In the design, be equipped with resilient snubber in the first die pipe fitting trough 311, second die pipe fitting trough 321, the pressure utilizing the elastic deformation of resilient snubber buffering pipe fitting to be subject to, contributes to the deformation reducing pipe fitting.
First die pipe fitting trough 311, second die pipe fitting trough 321 runs through the first die 31 and the second die 32 respectively, and add the length range of the pipe fitting that this device is suitable for, its range of application is wider.
The pipe fitting apparatus for bending that the present invention proposes, can realize the bending operation to pipe fitting, and its bending angle is controlled, bending efficiency is high.
The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
