Abstract

The utility model discloses a pipe cutter, a supporting frame of which is connected with a machine frame. One end of the machine frame is provided with blades and a speed reducer of a cycloidal gear, and the other end is connected with a positioning device; the supporting frame is provided with a set of positioning holes which can be used for elevating the height of the machine frame and the blades; both sides of a base seat are provided with a set of bearing seats which are matched with a pair of rollers used for supporting pipe with different size, which makes the pipe cutter possible to cut the pipes with different size, and increases the range of uses; a rotating shaft is composed of a main shaft and a shaft sleeve which are sheathed together, which facilitates the disassembly of the blades, improves work efficiency and reduces labor intensity.

Description

Pipe cutting machine

Technical field the utility model is a kind of pipe cutting machine of incising pipes.

What the existing incising pipes of background technology used is abrasive wheel cutting machine or electric pipe threading machine, and they have different defectives, and spark and iron filings are arranged during the emery wheel cutting operation, and big the healthy of operating personnel that influence of noise polluted the surrounding environment health; The electric pipe threading machine cutting output is big, waste tubing is many, and labour intensity is bigger, they also exist common problem: the straight and even perpendicularity of cutting end face can not be consistent, and the caliber of cutting can not be greater than 150cm, the popularity of the scope of purposes is placed restrictions on, and does not satisfy user's requirement.

Summary of the invention is in order to enlarge the scope of application of existing Pipe Cutting equipment, and the applicant has designed a kind of pipe cutting machine that can cut the large and small different pipes of caliber.

This pipe cutting machine of realizing above-mentioned purpose includes base, frame, blade, Cycloidal Wheel reductor and positioner, support one end on the base connects frame, the front end attaching blade of frame, positioner connects the other end of base and frame, this positioner has hydraulic mandril and extension spring, one group of locating hole is arranged on the support, connect with the frame axis hole, one group of bearing block is arranged on the wallboard of base both sides, dock a pair roller, blade is connected the rotating shaft that links to each other with the Cycloidal Wheel reductor by clamping plate, rotating shaft is connected on the frame, rotating shaft is made up of main shaft and axle sleeve, and they patch connection, is located by bearing pin between two clamping plate and the blade.

The utility model is equipped with a pair roller rest and rotates the pipe that is cut on base, keep the rotation cutting of blade to pipe, reduce noise, main shaft and axle sleeve join can demolition, is convenient to the attaching blade, improves work efficiency and reduces light work intensity, one group of bearing block that big small distance on one pair roller and the base does not wait is matched, can make the vary in size pipe of caliber of this pipe cutting machine cutting, function of use is more complete, satisfies user's different needs.

Description of drawings Fig. 1 is the utility model topology view.

Fig. 2 is a blade attaching topology view.

The 1-frame, 2-blade, 3-clamping plate, 4-main shaft, 5-Cycloidal Wheel reductor, sieve's 6-cap, 7-bearing block, 8-roller, 9-top pin, 10-base, 11-support, 12-hydraulic pressure top pestle, 13-extension spring, 14-locating hole, 15-axle sleeve, 16-bearing pin.

The specific embodiment describes technology contents of the present utility model in detail below in conjunction with accompanying drawing: the base 10 of this pipe cutting machine has fixing support 11, support 11 other ends connect frame 1, be processed with one group of (3-4 only) locating hole 14 on the arm of support 11 respectively, frame 1 connects with support 10 axis holes, select for use and connect locating hole 14, the height that can lifting fixed frame 1 and the height of blade 2, frame 1 other end connects hydraulic mandril 12 and extension spring 13, hydraulic mandril 12 can be with frame 1 lift adjustment height, one can keep the stable and balance of frame, the two pipe corresponding matching that vary in size that can keep the pair roller 8 on blade 2 and the base 10 to support, the different pipe of cutting caliber is consulted Fig. 1.The attaching of frame 1 one end blades 2: blade 2 is fixed on the main shaft 4 between two clamping plate 3 and by clamping plate 3, one clamping plate 3 are connected as a single entity with main shaft 4, another clamping plate 3 are by sieve cap 6 crimping main shafts 4, there are three or four bearing pins 16 to be located by connecting between blade 2 and two

clamping plate

3,4 one on the main shaft frame 1 wallboard bearing assembling activity that coexists connects, its head end is connected with Cycloidal Wheel reductor 6 rotating shaft keyways, drive blade 2 rotations, the other end of main shaft 4 is inserted with axle sleeve 15 covers and is linked to each other, axle sleeve 15 other ends flexibly connect with frame 1 another wallboard running in bearings, consult Fig. 2.This axle sleeve 15 of demolition, turn sieve cap 6 can load and unload blade 2.Corresponding one group of semicircle bearing block 7 is arranged on the base 10 end face both sides wallboards, the utility model is equipped with three pairs of corresponding bearing blocks 7, the rotating shaft of one pair roller 8 is connected on the respective shaft bearing 7, select distance bearing block 7 attaching rollers 8 not of uniform size for use, the pipe that varies in size with the movable supporting caliber is complementary, cut the pipe that caliber differs, can cut the pipe of maximum caliber 350cm.10 4 corners of base be equipped with four can upper and lower lifting screw thread top pin 9, can adjust the height and the levelness of base 10, consult Fig. 1.

When the pipe of cutting length, can connect a conduit saddle annex at another headrest at pipe, make pipe keep level, can better keep the cut surface glacing flatness.
