Description
Technical field
The utility model relates to a kind of 180 ° of bending machines, particularly relates to the improvement to 180 ° of bending machine tube head folders.
Background technology
During bend pipe, usually by the end winding support of a hollow straight pipe on the bend pipe rotating disk of bending machine, when bend pipe dial rotation, make tube bending to the shape that sets by the extruding between squeegee roller and bend pipe rotating disk, because pipe is generally hollow shape, yielding in extrusion process.The name that applicant submitted on January 20th, 2009 to State Bureau is called " Novel tube bender of 180 DEG ", application number is the utility model patent of " 2009200377055 ", by arranging plug in pipe, play the effect of support, bend pipe, thus avoid tube wall deformation problem.But find in actual use, the end of pipe is fixed on bend pipe rotating disk by tube head folder, when bend pipe dial rotation, the end under tension of pipe, yielding, interior flat.Therefore, in subsequent job, cut or shaping change shape position, but the former causes waste of material, improve production cost, the latter's labour intensity is large, wastes time and energy.
Utility model content
The utility model, for above problem, provides a kind of energy fixing tube end, makes bend pipe effective, reduce production cost, the modified of increasing work efficiency 180 ° of bending machines.
The technical solution of the utility model is: comprise frame, bend pipe rotating disk, tube head folder, plug, described plug is connected on frame or ground by the plug strong point, described frame has an inlet pipe point of contact relative to described bend pipe rotating disk, the core rod end of described plug is in oval spherical, the end points of oval spherical described core rod end exceedes described inlet pipe point of contact 10 ~ 20 millimeters
Described bend pipe rotating disk is provided with some fixing holes;
Described tube head folder comprises the L shape hook and support geometrical clamp that are connected, described hook one end is located on described support geometrical clamp, the other end and described fixing hole suitable, described support geometrical clamp comprises the outer support and round table-like inner support that are connected, described outer support is hollow circular cylinder and cross section is concave shape, and described inner support is located in described outer support.
The Internal periphery shape that the shape of oval spherical described core rod end and pipe are out of shape rear region at described inlet pipe point of contact is suitable.
The end face of described inner support protrudes from the end face of described outer support.
The utility model by arranging plug in pipe, when effectively preventing bend pipe tube wall occur in flat phenomenon.The fixed end cap of pipe and bend pipe rotating disk is provided with the support geometrical clamp of inner support and outer support, and utilize hook to be fixed on bend pipe rotating disk by support geometrical clamp, guarantee that the end of pipe can keep the shape of bend pipe when bend pipe, prevent interior flat, eliminate follow-up shaping and cutting action, improve the utilization rate of material, reduce production cost, increase work efficiency.Simultaneously inner support be round table-like, makes tube head folder be applicable to the pipe of multiple wall thickness of same external diameter, different inner diameters, improves the applicability of bending machine.

Detailed description of the invention
The utility model as Figure 1-4, comprise frame 1, bend pipe rotating disk 2, tube head folder 3, plug 7, described plug 7 is connected on frame 1 or ground by the plug strong point 8, described frame 1 has an inlet pipe point of contact 6 relative to described bend pipe rotating disk 2, the core rod end 5 of described plug 7 is in oval spherical, and the end points of oval spherical described core rod end 5 exceedes described inlet pipe point of contact 6 10 ~ 20 millimeters.
The Internal periphery shape that the shape of oval spherical described core rod end 5 and pipe 4 are out of shape rear region at described inlet pipe point of contact 6 is suitable.
Described bend pipe rotating disk 2 is provided with some fixing holes 21.
Described tube head folder 3 comprises the L shape hook 31 and support geometrical clamp 32 that are connected, described hook 31 one end is located on described support geometrical clamp 32, the other end and described fixing hole 21 suitable, described support geometrical clamp 32 comprises the outer support 321 and round table-like inner support 322 that are connected, described outer support 321 is hollow circular cylinder and cross section is concave shape, and described inner support 322 is located in described outer support 321.
The end face of described inner support 322 protrudes from the end face of described outer support 321, makes described inner support 322 first be inserted in pipe 4 inwall, more described outer support 321 is inserted in the outer wall of pipe 4, convenient operation.
