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 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; 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 cutting pipe, especially have otch smooth, cut labour-saving pipe saw.
Background technology
The sawing of current known CN107070397C pipe and chamfering device, it is by driver part, and toolroom machine clamping device forms, and toolroom machine is filled side by side by the cutter of circular saw bit and the rose reamer of circular peripheral-mill and forms on a shaft, motor removes driven tool machine, sawing simultaneously and chamfering heavy wall pipe.This toolroom machine is applicable to manufactory's batch machining pipe fitting, but can not be used for pipe mechanic and work as pipe cutting tool.The pipe cutter of existing conventional cutting pipe, it utilizes blade to extrude rotation, pipe is extruded inclined-plane and cuts off, more suitable to the less demanding use of pipe section.Pipe section is required that smooth impulse-free robustness just can not be used.Also there is effort.
Summary of the invention
There is the deficiency of cutting section injustice, jagged, effort to overcome pipe cutter, object of the present invention provides that a kind of pipe cutting section is smooth, labour-saving pipe saw.
The present invention's adopted technical scheme of dealing with problems is: it comprises round shell, slide block, recessed spiral fluted disc, saw blade, push rod, spring, bolt, handle, 4 slider bore are evenly provided with at circle shell periphery, circle shell side is flexibly connected one piece of recessed spiral fluted disc of planar square, slide block side is provided with the convex helical tooth of planar square, 4 pieces of slide blocks are contained in round shell 4 holes respectively, rotate recessed spiral fluted disc, 4 that respectively 4 pieces of slide block epirelief helical tooths are screwed on recessed spiral fluted disc one by one square recessed helical tooth internal fixtion slide blocks, rotate recessed spiral fluted disc, 4 pieces of slide blocks move up and down simultaneously, slide block one end is provided with elongated hole, push rod and spring is loaded in hole, push rod microcephaly passes 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 is connected with push rod microcephaly, handle ratchet is connected with circle shell.During saw pipe, pipe is clipped on pipe wrench, and be enclosed within pipe by pipe saw, adjust recessed spiral fluted disc, pipe is embraced by 4 pieces of slide blocks, and in 4 pieces of saw blade indentation slide block slots, 4 pieces of saw blades are pressed in pipe four sides by spring tension.Rotating operating handle 4 pieces of saw blades cut pipe simultaneously, and saw blade is energy automatic saw tube wall under the effect of spring tension, until cut off pipe, unclamps recessed spiral fluted disc 4 pieces of slide blocks and retreats simultaneously, takes out pipe saw.Because of pipe 4 saw blade cuts, pipe cutting section is smooth, impulse-free robustness, laborsaving, thus reaches that pipe cutting section of the present invention is smooth, labour-saving object.
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, laborsaving.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
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 7, recessed spiral fluted disc 7-1, hand be 7-2, screw 8, handle
Detailed description of the invention
In the embodiment shown in Fig. 1,2, be evenly provided with 4 rectangular openings and a circle ratchet in circle shell 1 surrounding, circle shell 1 cylindrical is provided with long circular hole 1-1.Slide block 2 is provided with an elongated hole in the middle of rectangular upper end, lower end is provided with a groove, slide block 2 one side is provided with square convex helical tooth 2-1, planar square recessed spiral fluted disc 7 is provided with one piece of outstanding hand 7-1, recessed spiral fluted disc 7 side is provided with 4 square recessed helical tooths, recessed helical tooth is identical with the size and dimension of convex helical tooth 2-1, and screw 7-2 screws in hand in 7-1 screw through circular hole 1-1 on circle shell 1,7-1 is fixed hand.4 pieces of slide blocks 2 are inserted in round shell 1 four holes, rotate recessed spiral fluted disc 7, screwed in one by one by 4 pieces of slide block 2 epirelief helical tooth 2-1 respectively in 4 recessed helical tooths on recessed spiral fluted disc 7 and fixed by slide block 2,4 pieces of slide blocks 2 can be moved up and down 7-1 by rotating operation hand simultaneously, adapt to different size pipe.Operating grip 8 ratchet is connected with ratchet on circle shell 1, and unidirectional push-jump round shell 1 saws pipe.Put into push rod 5 and spring 4 in the hole of slide block 2, push rod 5 microcephaly passes slide block 2 other end, is compressed by spring 4 in bolt 3 advances through hole, and adjustment bolt 3 can adjust the pressure of spring 4 tension and saw blade 6.Saw blade 6 is contained in the groove of slide block 2 other end, can move up and down, and saw blade 6 is connected with push rod 5 microcephaly, and adjust recessed spiral fluted disc 7 during use and make 4 pieces of slide blocks 2 withstand pipe, screw 7-2 screws and 7-1 fixed hand.4 saw blades 6 press pipe surrounding, turning handle 8, and 4 saw blades 6 cut pipe by spring 4 tension simultaneously with one heart, and energy autofeed is until pipe cuts off, and this pipe is sawed four saw blades 6 and cut simultaneously, and cutting speed is fast, otch is smooth also laborsaving.
