Description

The hand electric screw-rolling machine

Technical field

The utility model relates to pipe fitting machining tool technology, particularly relates to a kind of technology of hand electric screw-rolling machine.

Background technology

The hand electric die head threading machine is for the portable power tool being tightly connected with threading on pipe fitting.But existing hand electric die head threading machine is all to adopt cutting way externally threaded at pipe fitting outer wall processing tube, this has not only wasted a large amount of steel, and it's a pity the most on the pipe fitting outer wall through the anticorrosive coat of overpickling galvanizing by dipping by 100% machined away, also reduction at double of the multiple mechanical and physical performance that makes pipe fitting.

Existing hand electric die head threading machine is to adopt the machining mode at the outer wall of steel pipe threading, adding, the man-hour torque is larger, 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 the cold rolling forming technique can retain pipe fitting outer wall anticorrosive coat with threading on pipe fitting being tightly connected, but the existing machinery of cold rolling forming technique that adopts is all heavier, inconvenient operating personnel carries.

The utility model content

For the defect existed in above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of energy and retains pipe external screw thread anticorrosive coat, and lightweight, easy to carry hand electric screw-rolling machine.

In order to solve the problems of the technologies described above, a kind of hand electric screw-rolling machine provided by the utility model, comprise handle, and described handle is provided with the runner that can rotate relative to handle, and be provided with the motor for driving runner to rotate;

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 the jump ring of energy along 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 outwardly positioning edges, and be equipped with the clamping recess on every positioning edge, each positioning edge props up respectively four inner corner portion in hole from all directions, and the jump ring of hole inwall snaps in respectively the clamping recess on each positioning edge from all directions.

The hand electric screw-rolling machine that the utility model provides, utilize cylindrical die roll roll forming external screw thread on steel pipe fitting, can retain pipe external screw thread anticorrosive coat, and do not need liner, there are characteristics lightweight, easy to carry, and, by clip-connecting rod and coordinating of hole from all directions, can easily dismantle the cylindrical die roll coiled hair, the cylindrical die roll coiled hair that therefore single handle 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 the accompanying drawing explanation, embodiment of the present utility model is described in further detail, but the present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof, all should list protection domain of the present utility model in.

As shown in Fig. 1-Fig. 7, a kind of hand electric screw-rolling machine that the utility model embodiment provides, comprise handle 10, and described handle 10 is provided with the runner 8 that can rotate relative to handle, and be provided with the motor (not shown) for driving runner 8 to rotate;

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 cylindrical die roll 3(the present embodiment of at least three rotations four cylindrical die rolls are arranged around its ring axle on cylindrical die roll coiled hair 1), 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 utility model embodiment, 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 the jump ring 9 of energy along the radial expansion in hole 6, all directions from all directions;

Described cylindrical die roll coiled hair 1 is provided with an annular clip-connecting rod 2, described clip-connecting rod 2 is coaxial with cylindrical die roll coiled hair 1, and the internal diameter of clip-connecting rod 2 is consistent with the internal diameter of cylindrical die roll coiled hair 1, the outer peripheral face axial symmetry of clip-connecting rod 2 is provided with four outwardly positioning edges 4, and be equipped with clamping recess 5 on every positioning edge 4, each positioning edge 4 props up respectively four inner corner portion in hole 6 from all directions, and the jump ring 9 of hole inwall snaps in respectively the clamping recess 5 on each positioning edge 4 from all directions.

The using method of the utility model embodiment is as follows:

Pipe fitting to be processed is inserted in the cylindrical die roll coiled hair in ring, then drive the runner one-directional rotation by the motor on handle, because four positioning edges of clip-connecting rod outer peripheral face prop up respectively four inner corner portion in hole from all directions, therefore also transfer thereupon of cylindrical die roll coiled hair, the jump ring of hole inwall can avoid clamping joint to deviate from the hole, all directions from all directions, along with the rotation of cylindrical die roll coiled hair, each cylindrical die roll rolls out external screw thread at the outer wall of pipe fitting;
