Abstract
The invention relates to a die, and in particular relates to a cylindrical pipe flanging die which comprises an inner core shaft, an inner core pipe, a gasket and an outer core shaft housing, and is characterized in that the outer diameter of the inner core pipe is smaller than that of the inner core shaft and the inner core pipe is connected with the inner core shaft; a step is formed at one end of the inner core shaft and the gasket is in slide fit with the step of the inner core shaft; the side faces of the inner core shaft are partially plane-shaped; and the outer core shaft housing is provided with a flanging step inwards. The cylindrical pipe flanging die is characterized in that the inner core shaft housing is provided with the flanging step, the gasket is sleeved to the step and can be assembled and disassembled optionally, and the inner core shaft is pulled out after processing while the gasket is still left in an end of the cylindrical pipe; with small length, the gasket can be turned by 90 degrees to avoid stretching steps in side face holes of the cylindrical pipes, so that the technical problem of completing flanging machining from two positions toward the interior of the pipe at a near distance with high mechanical efficiency for the same pipe is solved.
Description
Technical field
The present invention relates to a kind of mould, refer more particularly to a kind of cylindrical tube flanging die.
Background technology
Existing thin-wall metal pipe kind is more; The most producers that manufacture of pad that are used between the thin-wall metal pipe on radiator and the heat exchanger product adopt the counterpart welding; To be that the thin welding of tube wall density unevenness is even be prone to leak its shortcoming, and as adopting the flange welding pretty good, but the big efficient of manual flange labour intensity is low; Make troubles to operation, particularly existing flange draws on the basis of stretching step and more in-plant cylinder beading tube ends just has been not easy mechanical flange in a cylindrical tube lateral aperture.
Summary of the invention
The object of the present invention is to provide a cylindrical tube flanging die, as prior processing requirements, to the hole of the cylindrical tube side flange stretching steps, resulting in the cylindrical tube at steps stretching the hole flanging smaller size, but must at the same end face of the inner cylindrical tube only flange, which is designed in the same conditions, to overcome the above drawbacks of the prior art, one tube to ensure uniform body two flanging, to use.
For realizing above-mentioned purpose; Technical scheme of the present invention is: the cylindrical tube flanging die; Comprise: inner spindle, inner core tube, pad, outer core sleeve form, and it is characterized in that: said inner core tube external diameter is connected less than inner spindle and with inner spindle, and inner spindle one end has step, pad and inner spindle step to be slidingly matched; Part, inner spindle side is plane, and inwardly there is the flange step in outer core sleeve.
The beneficial effects of the present invention: cylindrical mold lapped pipe end processing steps are very common, but the hole in the side of the cylindrical tube flanging already stretching step and then close on the basis of a cylindrical tube end flange is not very common The processing steps, because the lateral hole of the cylindrical tube stretching step of the cylindrical tube bore size becomes smaller, the normal inner mandrel into the inner tube can not be worn without internal mandrel would not be able to achieve mechanical flanging, which requires The creativity of the present invention to solve part of the inner side of the mandrel mill out a planar shape, which is characterized by a flange sleeve stepped inner core, the spacer and can be set in the steps above assembly disassembly, out of the inner mandrel after processing , gaskets remain in the cylindrical tube end, due to the short length can be rotated 90 ° to avoid open cylindrical tube side holes stretching step, therefore, resolved with a pipe, in close proximity to the tube for two mechanically efficient completion of the turn Edge Processing of technical difficulties.
Description of drawings
The structural representation of Fig. 1 cylindrical tube flanging die.
Fig. 2 is the cutaway view of inner spindle.
Fig. 3, be outer core sleeve.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further:
Cylindrical tube flanging die of the present invention such as Fig. 1, Fig. 2, shown in Figure 3; Comprise: comprising: inner spindle 1, inner core tube 2, pad 3, outer core sleeve 4 form; It is characterized in that: said inner core tube 2 external diameters are connected less than inner spindle 1 and with inner spindle 1; Inner spindle 1 one ends have step, pad 3 and inner spindle 1 step to be slidingly matched, and part, inner spindle 1 side is plane 5, and inwardly there is the flange step in outer core sleeve 4.
During the operation process of the invention: the cylindrical tube side holes stretching step machined flange connecting tube put inside the inner core tube and mandrel wear into the inner tube, the inner core sleeve with flange inward steps, mats kits on the steps and can be freely sliding fit, when one end of the cylindrical tube gasket sets on the steps, placed in the outer core sleeve can put one end of the cylindrical tube cylindrical tube side flanging, and draw the connection process is completed inner core tube and the inner mandrel, gaskets because short length can be rotated 90 ° to avoid open hole stretching cylindrical tube side steps, you can use the machine efficiently complete burring.
Embodiment recited above describes preferred implementation of the present invention; Be not that design of the present invention and protection domain are limited; Under the prerequisite that does not break away from design concept of the present invention; Common engineers and technicians make technical scheme of the present invention in this area various modification and improvement all should fall into protection scope of the present invention.
