It should be understood that the embodiments described herein are merely for the purpose of illustrating the invention and are not intended to limit the invention.

As shown in fig. 1-7, a tubular product spinning draws equipment to one side, the main part is including being used for fixed tubular metal resonator 12 and driving tubular metal resonator 12 together rotatory rotating

main shaft

1, 1 one side of rotating main shaft is equipped with spinning oblique stretching device 2, spinning draws device 2 to one side and includes the rotatory oblique pinch roller 3 that inclination set up, one side of rotatory oblique pinch roller 3 is equipped with and is used for driving rotatory oblique pinch roller 3 along the first horizontal feed ejector pad 4 of X axle direction walking, the upper end of rotatory oblique pinch roller 3 is equipped with the lift ejector pad 5 that is used for driving rotatory oblique pinch roller 3 along the walking of Y axle direction.

As the spinning draws device 2 structure further embodiment to one side, spinning draws device 2 to one side still includes base slider 6, and base slider 6 upper end is equipped with rotatory top wheel 7, and the upper end of rotatory top wheel 7 sets up rotatory oblique pinch roller 3, and base slider 6 one side is equipped with the second horizontal feed ejector pad that is used for driving rotatory top wheel 7 and rotatory oblique pinch roller 3 to walk along the X axle direction jointly.

In a preferred embodiment, the rotating inclined pressing wheel 3 and the rotating top wheel 7 are both rollers or bearings made of bearing steel. The roller or the bearing made of the bearing steel has very good strength and fatigue resistance, and can better and continuously carry out the diagonal tension flanging 13 work on the metal pipe 12. In addition, the rotating oblique pressing wheel 3 can also directly adopt a high-performance bearing, and the bearing is relatively standardized and can be directly purchased, so that the processing cost is relatively lower than that of a mode of customizing bearing steel.

The metal pipe 12 is a stainless steel pipe or a stainless iron pipe, or a steel pipe or an iron pipe, and the stainless steel pipe or the stainless iron pipe has good corrosion resistance, acid and alkali resistance, good use effect, relatively long service life, and good strength performance and tensile property, so the stainless steel pipe or the stainless iron pipe is preferably adopted as the metal pipe 12; and secondly, a steel pipe or an iron pipe (e.g., Q235, etc.) having good strength and tensile properties.

As a preferred embodiment, the first horizontal feeding pushing block 4, the lifting pushing block 5 and the second horizontal feeding pushing block 8 are hydraulic cylinders, or air cylinders or screw rod transmission members driven by servo motors.

As a preferred embodiment, the rotating main shaft 1 comprises a vertical rotating shaft 9, one end of the rotating shaft 9 is connected with a driving piece 10 for driving the rotating shaft 9 to rotate, a plurality of slotted holes 11 are arranged on the outer wall of the rotating shaft 9, lubricating oil can be stored more conveniently through the slotted holes 11, and in order to reduce cracks or deformation distortion of the metal pipe 12 in the inclined pressing and stretching process, the rotating main shaft 1 preferably controls the rotating speed range to be 500-600 revolutions per minute. The angle a of the rotating oblique pressing wheel 1 relative to the metal tube 12 is 165-185 degrees.

As an example of the driving member, the driving member 10 is a gear transmission structure, a pulley transmission structure, or the like. As shown in fig. 1-7, the principle of the present invention is:

the metal tube 12 is sleeved on the rotatable rotating main shaft 1, and the metal tube 12 is driven to rotate together by the rotating main shaft 1.

The inner wall of one side of the upper port of the metal tube 12 is contacted with a rotary inclined pinch roller 3 with an inclined angle; the rotary oblique pinch roller 3 realizes the movement and position adjustment work of the rotary oblique pinch roller 3 through the action of the first horizontal feeding push block 4 and/or the second horizontal feeding push block 8 and the lifting push block 5.

The rotating oblique pressing wheel 3 moves along one side of the horizontal direction, and the upper port of the metal pipe 12 in the rotating state is gradually stretched and deformed under the action of the extrusion force through the incremental change of the displacement distance of the rotating oblique pressing wheel 3, so that the stretching type flanging 13 is finally formed. In the process, oil or emulsion can be brushed between the rotary inclined pressing wheel 3 and the metal pipe 12 to prevent the pipe body of the metal pipe 12 from being abraded in the continuous friction process.

The effect that rotatory oblique pinch roller 3 set up relative metal tube 12's inclination is mainly in order to be can be when rotatory oblique pinch roller 3 contacts metal tube 12 inner wall, can force metal tube 12 outwards to carry out the predeformation effect in inclination's influence, thereby just can be better guarantee under the increment change of rotatory oblique pinch roller 3 displacement distance after, make metal tube 12 go up the port gradually and stable tensile deformation that takes place under the effect of the extrusion force, finally form the turn-ups 13 of high-quality tensile formula.

The rotary top wheel 7 can further match with the rotary oblique pressing wheel 3 to the flanging 13 needing to be stretched, the outer circular surface of the rotary top wheel 7 is tightly attached to the lower surface of the stretched flanging 13 of the metal pipe 12, and the rotary top wheel rotates along with the metal pipe 12 when pushing against the lower surface of the flanging 13.

Can follow the lower surface of the tensile turn-ups 13 of up roof pressure down through rotatory top wheel 7, at the rotatory in-process of tubular metal resonator 12, can with rotatory oblique pinch roller 3 to the pressfitting about the formula of stretching turn-ups 13 part opposite-clamping, not only can effectively ensure the roughness on the surface of tensile turn-ups 13, and can also regard as the spacing support of tensile turn-ups 13 lower surface orientation, effectively ensure tensile turn-ups 13 can not whole downwarping at tensile in-process, then fine assurance turn-ups 13 stretch forming's quality. In addition, the rotating inclined pressing wheel 3 and the rotating top wheel 7 are both of a driven wheel structure, and both rotate along with the metal pipe 12.

Since the existing metal drawing process is implemented by a drawing die and a stamping device, if the metal tube 1 is drawn by the drawing die, the structure is very complex, the effect is difficult to expect, a punching machine with a large tonnage is also needed for drawing the stainless steel, a lot of disadvantages exist in the aspects of processing efficiency and safety, and the cost required by the device is very high.

The utility model discloses an in the aspect of the structure stretch the device to one side through the spinning and stretch turn-ups 13 to metal tubular product, not only the appearance is effectual, and this mode can be once only shaping on the metal pipe moreover, and need not other process steps, also need not large-scale punch press and complicated tensile mould in the aspect of the processing, and product quality obtains the guarantee easily, and the yield is high, for the mode of traditional punch press of big tonnage and complicated tensile mould, low cost, simple operation, production efficiency is high.

The foregoing is considered as illustrative of the preferred embodiments only, and it is understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
