Abstract
The invention discloses a pipe saw for cutting a pipe. The pipe saw comprises a circular casing, slide blocks, a concave helical gear disc, saw blades, ejector rods, springs, bolts and handles, wherein 4 slide block holes are circumferentially and uniformly formed in the circular casing; the planar square concave helical gear disc is movably connected to one side of the circular casing; a planar square convex helical gear is arranged on one side of each slide block; four even concave helical gears are arranged on one side of the concave helical gear disc and are the same as the convex helical gears on the slide blocks in shape and size; four slide blocks are mounted inside the four holes of the circular casing; the concave helical gear disc is rotated, and the convex helical gears on the four slide blocks are gradually rotated one by one into four square concave helical gears on the concave helical gear disc so as to fix the slide blocks; the concave helical gear disc is rotated, and the four slide blocks move up and down at the same time; a long hole is formed in one end of each slide block; the ejector rod and the spring are mounted inside the long hole; the small end of the ejector rod penetrates out of the other end of the slide block; the bolt is screwed into the slide block hole to press the spring; a saw blade groove is formed in the other end of the slide block; the saw blade is mounted inside the saw blade groove and is connected with the small end of the ejector rod; the four saw blades press on the four faces of the pipe through expanding force of the springs and cut the pipe at the same time; each handle is connected with the circular casing through a pawl. By adoption of the structure, the pipe saw cuts the pipe by using four saw blades at the same time, so that the pipe saw can cut the pipe rapidly with a smooth and flat cut and without burrs, is labor-saving, and is a good tool for a pipe repairer.
Description
Technical field
The present invention relates to a kind of instrument of cutting pipe, especially have that otch is smooth, cutting labour-saving pipe saw.
Background technology
It is currently known CN107070397C pipe sawing and chamfering device, it is by driver part, toolroom machine clamping device group
Become, toolroom machine is made up of on a shaft the cutter of circular saw bit and the rose reamer of circular peripheral-mill dress arranged side by side, motor goes to drive
Power driven tools machine, sawing simultaneously and chamfering heavy wall pipe.This toolroom machine is applied to maker batch machining pipe fitting, but cannot be used for
Pipe mechanic works as pipe cutting tool.Commonly use the pipe cutter of cutting pipe, it utilizes blade extruding rotation, and pipe is extruded
Inclined-plane cut off, less demanding to pipe section using appropriate.Require smooth impulse- free robustness cannot use pipe section.Also
Exist laborious.
Content of the invention
Uneven, jagged, laborious in order to overcome the shortcomings of that pipe cutter has a cutting section, it is an object of the invention to provide one
Kind pipe cutting section is smooth, labour-saving pipe saw.
Solve problem of the present invention be employed technical scheme comprise that：It includes circle shell, slide block, recessed spiral fluted disc, saw blade, top
Bar, spring, bolt, handle, are uniformly provided with 4 slider bore in circle shell periphery, it is recessed that circle shell side is flexibly connected one piece of planar square
Spiral fluted disc, slide block side is provided with the convex helical tooth of planar square, and recessed spiral fluted disc side is provided with uniform 4 recessed helical tooths, recessed spiral shell
Rotation tooth is identical with the shape and size of the convex helical tooth of slide block, and 4 pieces of slide blocks are attached separately to circle 4 in the holes of shell, rotate recessed helical tooth
Convex for 4 pieces of slide blocks helical tooth is screwed in 4 square recessed helical tooths on recessed spiral fluted disc and fixes slide block, turns by disk respectively one by one
Move recessed spiral fluted disc, 4 pieces of slide blocks move up and down simultaneously, slide block one end is provided with elongated hole, in the hole loads push rod and spring, push rod microcephaly
Pass the slide block other end, bolt is spun on pressing spring in slider bore, the slide block other end is provided with saw blade groove, saw blade is contained in groove and top
Bar microcephaly connects, and 4 pieces of saw blades are pressed in pipe four sides by spring tension and cut pipe simultaneously, and handle ratchet is connected with circle shell.
During saw pipe, pipe is clipped on pipe wrench, pipe saw is enclosed within pipe, adjusts recessed spiral fluted disc, pipe is embraced by 4 pieces of slide blocks, 4 pieces
In saw blade indentation slide block slot, 4 pieces of saw blades are pressed in pipe four sides by spring tension.4 pieces of saw blades of rotating operating handle cut simultaneously
Pipe, saw blade energy automatic saw tube wall under the effect of spring tension, until cut-out pipe, unclamp recessed 4 pieces of slide blocks of spiral fluted disc same
When retreat, take out pipe saw.Because pipe is with 4 saw blade cuts, pipe cutting section is smooth, impulse- free robustness, laborsaving, thus reaching this
Invention pipe cutting section is smooth, labour-saving purpose.
The invention has the beneficial effects as follows, pipe cutting section is smooth, and also because there being 4 saw blades to saw simultaneously, saw pipe speed is fast, province
Power.
Brief description
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 Fig. 2 is the mutual profilograph of embodiment of the present invention A-A, B-B.
In figure 1, circle shell 1-1, circular hole 2, slide block 2-1, convex helical tooth 3, bolt 4, spring 5, push rod 6, saw blade
7th, recessed spiral fluted disc 7-1, handle 7-2, screw 8, handle
Specific embodiment
In embodiment shown in Fig. 1,2, it is uniformly provided with 4 rectangular openings and a circle ratchet in circle shell 1 surrounding, outside circle shell 1
Circle is provided with long circular hole 1-1.It is provided with an elongated hole, lower end is provided with a groove, slide block 2 one side sets in the middle of the rectangular upper end of slide block 2
Have square convex helical tooth 2-1, planar square recessed spiral fluted disc 7 be provided with one piece prominent handle 7-1, recessed spiral fluted disc 7 side sets
There are 4 square recessed helical tooths, recessed helical tooth is identical with the size and dimension of convex helical tooth 2-1, screw 7-2 passes through circle on circle shell 1
Arc hole 1-1 screws in and handles in 7-1 screw, will handle 7-1 and fix.4 pieces of slide blocks 2 are inserted into round 1 four in the holes of shell, rotate recessed spiral
