Abstract

The invention discloses a pipe cutter for cutting a metal pipe. The pipe cutter mainly comprises a closed cutter holder, two arc-shaped cutter holders, a balancing wheel frame, circular cutters, connecting shafts, rotating buttons and a balancing wheel. The pipe cutter is characterized in that a groove provided with a top-bottom through hole is formed in an arc-shaped end of the closed cutter holder, and a closed hole is formed in a rectangular end of the closed cutter holder; bulges provided with holes are arranged at two ends of one arc-shaped cutter holder, and grooves provided with top-bottom through holes are formed in two ends of another arc-shaped cutter holder; a bulge provided with a hole is arranged at the arc-shaped end of the balancing wheel frame, and a cylindrical cutter feeding pulling rod provided with a screw buckle is arranged at the other end of the balancing wheel frame; the circular cutters are arranged in the middle parts of the closed cutter holder and the two arc-shaped cutter holders; the balancing wheel is arranged at the inner side of the middle part of the balancing wheel frame; the rotating buttons are arranged at the upper parts of the closed cutter holder, the two arc-shaped cutter holders and the balancing wheel frame and are interconnected through the connecting shafts in an end-to-end manner; the cutter feeding pulling rod passes through the closed hole in the rectangular end of the closed cutter holder, and a nut is arranged at the end part of the cutter feeding pulling rod. The pipe cutter has the advantages of being small in size, light in weight, small in rotating radius, and high in efficiency, and combining a plurality of cutters.

Description

A kind of pipe cutter

Technical field

The present invention relates to a kind of device of cutting metal tubing, specifically a kind of pipe cutter of cutting metal tubing, belongs to field of mechanical technique.

Background technology

In the maintenance work of the metallic conduit such as water supply and sewage, heating, often can run into because of situations such as pipeline rust or pipe fitting explosion, pipe leakages, need to change defectiveness position pipeline.The metallic conduit cutting mode often used at present has usually: pipe cutter cutting, Arm saw cutting and acetylene high-temperature machining three kinds of modes.The saw bow length of Arm saw cutting hacksaw, greatly about 40 cm, to move back and forth and the distance of arm then needs larger space operationally, then cannot use in less space and trench, acetylene high-temperature machining then to workplace and environmental requirement extremely strict, its transport and use cost also higher, because acetylene cutting belongs to high-temperature machining, the fusing point of iron is at 1535 DEG C, and temperature will be higher in real work, even as also burst by its hot high temperature barbecue produced from the nearly cement wall surface of metope or floor or tile floor in cutting, and the molten iron cut down splashes under the blowing of oxygen very easily scorches article and causes fire, cannot use in office space and resident's family, larger at the confined space such as trench or piping shaft operating safety, at present, generally use pipe cutter to cut in less space, pipe cutter is made up of arc knife rest, guide pad, cutter guided way, cutter, roller, boosting lead screw, handle etc.By axle, a circular cutter is installed in the front end of arc knife rest, the hole of interior threading is had at its rear portion, cylindrical boosting lead screw is through the hole at arc knife rest rear portion, T-shaped handle is installed at boosting lead screw rear portion, inside arc knife rest, be provided with cutter guided way, guide pad installed by cutter guided way, guide pad can move on cutter guided way, boosting lead screw front portion heads on guide pad rear portion, installs two rollers respectively up and down in the anterior corresponding cutter position of guide pad.During work, cutter and two rollers are stuck on the metal pipe of processing, rotate T-shaped handle and make boosting lead screw front portion hold out against guide pad rear portion, while reinforcing around pipe at least rotating 360 degrees carry out extruding cutting.Although this pipe cutter can use in less space, but because its needs just can complete cutting around pipe integral rotating 360 degrees, radius of turn is excessive, also because of its handle opening-closing length about 35 centimetres, and volume is larger, then cannot use in multitube arrangement or narrow space, service clearance is restricted.

Summary of the invention

It is little that task of the present invention is to provide a kind of volume, lightweight, and multitool combines, and radius of turn is little, the pipe cutter that efficiency is high.

For realizing above-mentioned task, technical solution of the present invention is:

A kind of pipe cutter, form primarily of closed knife rest 1, curve forming rest 7, curve forming rest 12, balance wheel frame 17, feed pull bar 21, circular cutter 5, circular cutter 10, circular cutter 15, connecting axle 6, connecting axle 11, connecting axle 16, knob 3, knob 8, knob 13, knob 18, stabilizer 20, described closed knife rest 1 one end is arc, curved end arranges the groove with upper and lower through hole, the other end is rectangle, rectangle end arranges lipostomous 2, middle part arranges circular cutter 5, and top arranges knob 3, curve forming rest 7 two ends arrange the projection with hole, and middle part arranges circular cutter 10, and top arranges knob 8, curve forming rest 12 two ends arrange the groove with upper and lower through hole, and middle part arranges circular cutter 15, and top arranges knob 13, balance wheel frame 17 one end is arc, and curved end arranges the projection with hole, and the other end is the cylindrical feed pull bar 21 that end has spiral shell button, and inside middle portion arranges stabilizer 20, and top arranges knob 18, the groove that closed knife rest 1 curved end has upper and lower through hole coordinates with the protruding grafting that curve forming rest 7 one end has hole, both are connected by connecting axle 6, the projection that curve forming rest 7 the other end has hole coordinates with the groove grafting that curve forming rest 12 1 end has upper and lower through hole, both are connected by connecting axle 11, the groove that curve forming rest 12 the other end has upper and lower through hole coordinates with the protruding grafting that balance wheel frame 17 curved end has hole, both are connected by connecting axle 16, the lipostomous 2 that cylindrical feed pull bar 21 is arranged through closed knife rest 1 rectangle end, feed pull bar 21 end arranges nut 22.

Described a kind of pipe cutter, its T-shaped handle 23 front end is provided with the pipe of screw thread in being, be connected with cylindrical feed pull bar 21.

It is little that the present invention has volume, lightweight, and multitool combines, and radius of turn is little, the advantage that efficiency is high.
