Existing hand electric die head threading machine is to adopt the machining mode at the outer wall of steel pipe threading, the man-hour torque is bigger adding, and can produce a large amount of cuttings, has not only wasted the steel of a large amount of preciousnesses, also polluted environment, the gas thread of completion of processing does not have anticorrosive coat fully.
Adopt cold rolling forming technique threading on being tightly connected with pipe fitting then can keep pipe fitting outer wall anticorrosive coat, but the existing machinery of cold rolling forming technique that adopts is all heavier, inconvenient operating personnel carries.
Summary of the invention
At the defective that exists in the above-mentioned prior art, technical problem to be solved by this invention provides a kind of energy and keeps pipe external screw thread anticorrosive coat, and hand electric screw-rolling machine in light weight, easy to carry.
In order to solve the problems of the technologies described above, a kind of hand electric screw-rolling machine provided by the present invention comprises handle, and described handle is provided with the runner that energy rotates relative to handle, and is provided with for driving the motor that runner rotates;
It is characterized in that: described runner is provided with a dismountable cylindrical die roll coiled hair;
Described cylindrical die roll coiled hair is annular disk body, its ring axle line overlaps with the pivot center of runner, be arranged with the cylindrical die roll of at least three rotations on the cylindrical die roll coiled hair around its ring axle, the pivot center of each cylindrical die roll all is parallel to the ring axle line of cylindrical die roll coiled hair, and the wheel face of each cylindrical die roll is all inwardly outstanding from the inner ring of cylindrical die roll coiled hair.
Further, described runner is provided with the hole, all directions of an octagon, and the hole heart axes in this hole, all directions overlaps with the pivot center of runner, and the inwall in hole is provided with energy along the jump ring of the radial expansion in hole, all directions from all directions;
Described cylindrical die roll coiled hair is provided with an annular clip-connecting rod, described clip-connecting rod is coaxial with the cylindrical die roll coiled hair, the outer peripheral face axial symmetry of clip-connecting rod is provided with four positioning edges that outwards protrude, and be equipped with the clamping recess on the every positioning edge, each positioning edge props up four inner corner portion in hole from all directions respectively, and the jump ring of hole, all directions inwall snaps in the clamping recess on each positioning edge respectively.
Hand electric screw-rolling machine provided by the invention, utilize cylindrical die roll roll forming external screw thread on steel pipe fitting, can keep pipe external screw thread anticorrosive coat, and do not need liner, has in light weight, convenient carrying, and by clip-connecting rod and cooperating of hole from all directions, can easily dismantle the cylindrical die roll coiled hair, therefore the single handle cylindrical die roll coiled hair that can be equipped with plurality of specifications is dealt with the pipe external screw thread process requirements of different size.

The specific embodiment
Below in conjunction with description of drawings embodiments of the invention are described in further detail, but present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar variation thereof all should be listed protection scope of the present invention in.
As Fig. 1-shown in Figure 7, a kind of hand electric screw-rolling machine that the embodiment of the invention provides comprises handle 10, and described handle 10 is provided with the runner 8 that handle relatively rotates, and is provided with the motor (not shown) for 8 rotations of driving runner;
It is characterized in that: described runner 8 is provided with a dismountable cylindrical die roll coiled hair 1;
Described cylindrical die roll coiled hair 1 is annular disk body, its ring axle line overlaps with the pivot center of runner 8, be arranged with in the cylindrical die roll 3(present embodiment of at least three rotations around its ring axle on the cylindrical die roll coiled hair 1 four cylindrical die rolls are arranged), the pivot center of each cylindrical die roll 3 all is parallel to the ring axle line of cylindrical die roll coiled hair 1, and the wheel face of each cylindrical die roll 3 is all inwardly outstanding from the inner ring of cylindrical die roll coiled hair 1.
In the embodiment of the invention, described runner 8 is provided with the hole, all directions 6 of an octagon, and the hole heart axes in this hole 6, all directions overlaps with the pivot center of runner 8, and the inwall in hole 6 is provided with energy along the jump ring 9 of the radial expansion in hole 6, all directions from all directions;
