Description

Technical Field

[0001] The utility model relates to the technical field of thin-walled pipe processing, in particular to a quick-change thin-walled pipe expanding device. Background Art

[0002] It is necessary to expand thin-walled tubes of various diameters, and the processing difficulties are: 1. Thin-walled tubes of various diameters require different expansion sizes and angles; 2. It is necessary to adapt to the delivery rhythm, and when expanding thin-walled tubes, it is possible to quickly switch to produce thin-walled tubes with different diameters, sizes and angles, while ensuring a certain number of batch deliveries. The original method was to use an ordinary expander on the market, because it requires the use of multiple parts for combined operation, the steps are cumbersome, time-consuming and labor-intensive, and the orifice molds it provides have different apertures, but the angles are unified. For thin-walled tubes with different expansion angles, personnel are required to use self-sharpening rotary knives for reprocessing, which can easily cause uneven orifices and affect the appearance.

[0003] In view of this, we propose a quick-change thin-wall tube expanding device. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides a quick-change thin-wall pipe expanding device.

[0005] The technical solution of the utility model is: it includes a base, and is characterized in that: the threaded fixing seat and the groove seat are fastened to the upper surface of the base by screws respectively on the base, the threaded fixing seat is connected with the threaded tube by internal threads to form a threaded transmission structure, the inner holes at both ends of the threaded tube are respectively installed with a bearing, the threaded tube forms a concentric structure with the feed type tool handle through the bearings at both ends, the feed type tool handle is limited to the installation position on the threaded tube by a rear cover, the top of the feed type tool handle is equipped with a reaming rotary cutter, the rear end of the feed type tool handle is connected with the crank handle by a pin, the groove seat is connected with the flip cover and the fastening screw by bolts and nuts, the fastening screw fastens the flip cover to the groove seat by a fastening screw sleeve, the flip cover and the groove seat are equipped with a half-tile forming sleeve, and a thin-walled tube is installed in the half-tile forming sleeve.

[0006] As a preferred technical solution, the assembly surfaces of the reaming rotary cutter and the feed-type tool holder adopt a Morse taper angle assembly structure.

[0007] As a preferred technical solution, the centers of the feed tool handle, the reaming rotary cutter, the groove seat, the half-tile forming sleeve, and the thin-walled tube are on the same axis.

[0008] As a preferred technical solution, four handles are welded to the outer circle of the rear end of the threaded tube.

[0009] As a preferred technical solution, the inner hole profile of the groove seat and the flip cover is consistent with the outer circular profile of the half-tile forming sleeve.

[0010] As a preferred technical solution, the flip cover and the fastening screw can be flexibly rotated on the groove seat through bolts.

[0011] As a preferred technical solution, the inner profile of the half-tile forming sleeve is consistent with the orifice profile of the thin-walled tube to be processed.

[0012] As a preferred technical solution, the half-tile forming sleeve has two pieces, which are formed by splitting and processing the same forming sleeve.

[0013] As a preferred technical solution, the fastening screw sleeve is provided with a handle.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By quickly replacing different reaming cutters and half-tile forming sleeves, thin-walled tubes with different diameters and angles can be expanded. Due to the use of Morse taper angles and uniform profiles, while ensuring quick-release efficiency, sufficient processing positioning accuracy can also be guaranteed. Through the structure of the groove seat, flip cover, fastening screw sleeve, and fastening screw, the parts can be quickly fastened and positioned, and the quick-release function can be achieved to ensure processing efficiency. Through the threaded transmission structure of the threaded tube and the threaded fixing seat, as well as the handle and crank structure, the processing of thin-walled tube expansion is more labor-saving and convenient.
