Description
Technical field
The present invention relates to pipe external screw thread machining tool technology, particularly relate to the technology of a kind of pipe external screw thread manual ratchet rolled thread plate.
Background technology
The manual ratchet lag of pipe external screw thread is at the portable manually-operated machine tool with threading on pipe fitting that is tightly connected.But the manual lag of existing pipe external screw thread is all adopt cutting way at pipe fitting outer wall threading, this not only wastes a large amount of steel, and to it's a pity on pipe fitting outer wall through the anticorrosive coat of overpickling galvanizing by dipping by 100% machined away the most, the multiple mechanical and physical performance making pipe fitting also reduction at double.
The manual ratchet lag of existing pipe external screw thread is all configured with liner, when pipe fitting outer wall threading, liner is needed first to insert in pipe fitting, in case pipe fitting gas thread indent modification in process, due to needs configuration liner, make existing pipe external screw thread manual ratchet lag relatively heavier, inconvenient operating personnel carries with, and existing pipe external screw thread manual ratchet lag all can only process the pipe external screw thread of single specification, the manual ratchet lag of pipe external screw thread purchasing different size is needed to deal with the pipe external screw thread process requirements of different size.
Adopt cold rolling forming technique then can retain pipe fitting outer wall anticorrosive coat with processing tube external screw thread on pipe fitting being tightly connected, but the machinery of existing employing cold rolling forming technique is all heavier, need power supply, inconvenient operating personnel carries with.
Summary of the invention
For the defect existed in above-mentioned prior art, technical problem to be solved by this invention is to provide one can retain pipe external screw thread anticorrosive coat, and lightweight, does not need power supply, pipe external screw thread manual ratchet rolled thread plate easy to carry.
In order to solve the problems of the technologies described above, a kind of pipe external screw thread provided by the present invention manual ratchet rolled thread plate, comprises handle, and described handle is provided with the ratchet that energy opposite handle rotates, and is provided with the ratchet matched with ratchet;
It is characterized in that: described ratchet 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 ratchet, cylindrical die roll coiled hair is arranged with at least three cylindrical die rolls rotated around its ring axle, the pivot center of each cylindrical die roll is all parallel to the ring axle line of cylindrical die roll coiled hair, and the wheel face of each cylindrical die roll is all inwardly given prominence to from the inner ring of cylindrical die roll coiled hair.
Further, described ratchet is provided with the hole, all directions of an octagon, and this all directions hole heart axes in hole overlaps with the pivot center of ratchet, 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 cylindrical die roll coiled hair, the outer peripheral face axial symmetry of clip-connecting rod is provided with four outwardly positioning edges, and every root positioning edge is equipped with clamping recess, each positioning edge props up four inner corner portion in hole from all directions respectively, and the jump ring of hole inwall snaps in the clamping recess on each positioning edge respectively from all directions.
Pipe external screw thread provided by the invention manual ratchet rolled thread plate, utilize cylindrical die roll roll forming external screw thread on pipe fitting, pipe external screw thread anticorrosive coat can be retained, and do not need liner, also do not need power supply, there is feature lightweight, easy to carry, and coordinating by clip-connecting rod and from all directions hole, can easily dismantle cylindrical die roll coiled hair, the pipe external screw thread process requirements of different size dealt with by the cylindrical die roll coiled hair that therefore single handle can be equipped with plurality of specifications.

Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and be described in further detail embodiments of the invention, but the present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar change thereof, all should list protection scope of the present invention in.
As shown in Fig. 1-Fig. 7, a kind of pipe external screw thread manual ratchet rolled thread plate that the embodiment of the present invention provides, comprises handle 10, and described handle 10 is provided with the ratchet 8 that energy opposite handle rotates, and is provided with the ratchet 7 matched with ratchet 8;
It is characterized in that: described ratchet 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 ratchet 8, cylindrical die roll coiled hair 1 is arranged with at least three cylindrical die rolls 3 rotated around its ring axle, the pivot center of each cylindrical die roll 3 is all 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 given prominence to from the inner ring of cylindrical die roll coiled hair 1.
In the embodiment of the present invention, described ratchet 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 ratchet 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 every root positioning edge 4 is equipped with clamping recess 5, each positioning edge 4 props up four inner corner portion in hole 6 from all directions respectively, and the jump ring 9 of hole inwall snaps in the clamping recess 5 on each positioning edge 4 respectively from all directions.
The using method of the embodiment of the present invention is as follows:
Pipe fitting to be processed is inserted in cylindrical die roll coiled hair inner ring, then turning handle, ratchet one-way is rotated, four positioning edges due to clip-connecting rod outer peripheral face prop up four inner corner portion in hole from all directions respectively, therefore cylindrical die roll coiled hair also transfer thereupon, the jump ring of hole inwall can avoid clamping joint to deviate from hole, all directions from all directions, and 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;
When needing to change cylindrical die roll coiled hair, force outwards pulls out cylindrical die roll coiled hair, makes the jump ring circumferentially extending of hole inwall from all directions, deviates from, cylindrical die roll coiled hair can be taken off from handle from the clamping recess each positioning edge.
