Abstract
The invention provides a 180 degrees pipe bender, relating to improvement of the mandril structure of the 180 degrees pipe bender. The pipe bender comprises a rack, a bent pipe turnplate, a pipe head clamp and a mandril, wherein the rack is provided with a feed pipe tangent point relative to the bent pipe turnplate; the end of the mandril is ellipsoidal; and the endpoint of the ellipsoidal end of the mandril exceeds the feed pipe tangent point by 10-20mm. The end of the mandril has ellipsoidal shape adaptive to the shape of the internal profile of the bent pipe, the deformation from straight pipe to bent pipe only happens in the deformation zone of the feed pipe tangent point, and the ellipsoidal end of the mandril becomes the support surface of the internal profile surface of the pipe which is just bent after stretching into the deformation zone, thus effectively avoiding the pipe from sinking down in the zone. After clamping the pipe with the pipe head clamp, the bent pipe turnplate carries out continuous feed, and the internal surface of the axial outside of the pipe is always positioned on the ellipsoidal support surface behind the feed pipe tangent point, thus manufacturing the regular 180 degrees pipe bender.
Description
Technical field
The present invention relates to a kind of 180 ° of bending machines, relate in particular to improvement 180 ° of bending machine mandrel structures.
Background technology
At present, 180 ° of bending machines are in the bend pipe process, and pipe can be at rear portion, bend pipe point of contact by curved flat.Its reason mainly is a pipe when being linearly moved to flexural deformation, the bending power the when intensity of tube wall is difficult to bear bend pipe.For overcoming this problem, we once passed through to place means such as bend pipe spring, yellow sand in pipe, but used complexity, and workload is big.
Summary of the invention
The present invention is directed to above problem, provide a kind of and supporting surface has been set, thereby avoid tube bending when distortion by curved 180 ° of flat bending machines at the pipe deformation point.
Technical scheme of the present invention is: comprise frame, bend pipe rotating disk, tube head folder, plug, have an inlet pipe point of contact with respect to the bend pipe rotating disk on the frame, it is oval spherical that described plug end is, and the end points of oval spherical plug end surpasses 10～20 millimeters at inlet pipe point of contact.
The shape of oval spherical plug end and pipe are suitable at the interior contour shape of inlet pipe point of contact distortion rear region.
The present invention the plug end be provided with one with tube bending after in suitable oval spherical of contour shape, pipe is by the deformed area that only occurs in the inlet pipe point of contact until curved distortion, and after oval spherical plug end stretches into the deformed area, become the supporting surface of contour surface in the just crooked pipe, suppress thereby effectively avoided pipe to become in this zone.After the bend pipe rotating disk is clamped pipe by tube head, continuous feed, the ellipsoidal surface that the inner surface in the axial outside of pipe always is positioned in rear portion, inlet pipe point of contact supports, and promptly makes 180 ° of regular bend pipes.
Description of drawings
Fig. 1 is a structural representation of the present invention
1 is frame among the figure, the 2nd, and bend pipe rotating disk, the 3rd, tube head folder, the 4th, pipe, the 5th, plug end, the 6th, inlet pipe point of contact, the 7th, plug, the 8th, the plug strong point.
The specific embodiment
The present invention comprises frame 1, bend pipe rotating disk 2, tube head folder 3, plug 7 as shown in Figure 1, and plug 7 is connected on frame 1 or the ground by the plug strong point 8.Have an inlet pipe point of contact 6 with respect to bend pipe rotating disk 2 on the frame 1, it is oval spherical that described plug end 5 is, and the end points of oval spherical plug end 5 surpasses inlet pipe point of contact 6 10～20 millimeters.
The interior contour shape of the shape of oval spherical plug end 5 and the pipe 46 distortion rear regions at the inlet pipe point of contact is suitable.
Claims (2)
1. 180 ° of bending machines, comprise frame, bend pipe rotating disk, tube head folder, plug, have an inlet pipe point of contact with respect to the bend pipe rotating disk on the frame, it is characterized in that, it is oval spherical that described plug end is, and the end points of oval spherical plug end surpasses 10～20 millimeters at inlet pipe point of contact.
2. a kind of 180 ° of bending machines according to claim 1 is characterized in that, the shape of oval spherical plug end and pipe are suitable at the interior contour shape of inlet pipe point of contact distortion rear region.
