Abstract

The utility model relates to a tube stripper for al plastics laminated pipes and pure plastic pipes, and the plastic pipe tube stripper of the utility model comprises a handle 21, a locating collar 22, a blade 23, a screw 24, and a locating pin 25. A bore of the locating collar 22 is provided with a locating post hole 221 and a guide post hole 222. A radial slot 223 is arranged at the transitional position of the locating post hole 221 and the guide post hole 222. The blade 23 is arranged on the lateral face 224 of the radial slot 223, and the screw 24 is utilized for adjusting and fastening the blade 23. The blade 23 can easily abscise unwanted layer outside a pipe through rotating the locating collar 22, in order to realize purpose of stripping. The plastic pipe tube stripper has the main advantages of labor saving operating, high efficiency, and great quality of stripped pipe surface.

Description

A kind of plastic pipe tube stripper

The utility model relates to pipelayer's tool, especially relates to the tube stripper that al-plastics composite pipe, pure-plastics pipe are used.

PAP be connected with multiple mode, if adopt the mode of thermal welding to connect plastic pipe, the outer layer polyethylene and the middle aluminium lamination of PAP to be peeled off earlier during installation, and then tubing is connected with pipe fitting with special-purpose thermal welding instrument.Existing stripping piping tool generally by hand cutter shell pipe, operating efficiency is low, the stripping tube-surface of poor quality.

The purpose of this utility model is to overcome the weak point of existing stripping piping tool, and a kind of operating efficiency height is provided, the measured tubing tube stripper of stripping tube-surface matter.

The utility model purpose is achieved in that the plastic pipe tube stripper, comprises handle 21, positioning sleeve 22, blade 23, screw 24, alignment pin 25; Be provided with reference column hole 221, lead hole 222 in the endoporus of positioning sleeve 22; Reference column hole 221 is provided with radial slot 223 with the transition position in lead hole 222; Blade 23 is located on the side 224 of radial slot 223, regulates and the position of fastening blade 23 with screw 24.By rotation positioning sleeve 22, blade 23 just can excise the unnecessary layer in tubing outside like a cork, realizes stripping pipe purpose.

Major advantage of the present utility model: rapid operation, the efficient height, stripping tube-surface quality is good.The utility model can be used for divesting the skin of PAP; When the skin of other pure-plastics pipe need be removed, the utility model also can adopt.

Be further described below in conjunction with the embodiment accompanying drawing.

Fig. 2 is positioning sleeve 22 topology views of embodiment one;

Fig. 3 is the view of the blade 23 of embodiment one;

Fig. 4 is the structure cutaway view of embodiment two of the present utility model;

Embodiment one:

Shown in Fig. 1～3, the plastic pipe tube stripper comprises handle 21, positioning sleeve 22, blade 23, screw 24, alignment pin 25.Positioning sleeve 22 is a hollow cylinder, is provided with reference column hole 221, lead hole 222 in its endoporus; Reference column hole 221 is provided with radial slot 223 with the transition position in lead hole 222; Blade 23 is located on the side 224 of radial slot 223, regulates and the position of fastening blade 23 with screw 24.Handle 21 is connected and fixed with positioning sleeve 22 by alignment pin 25.

The external diameter of the slightly larger in diameter in the reference column hole 221 on the positioning sleeve 22 before the tubing exploitation; The external diameter that the slightly larger in diameter in lead hole 222 needs after the tubing exploitation.

Blade 23 is provided with front cutting edge 231, rake face 232, rear knife edge 233, back knife face 234, and the angle α between front cutting edge 231 and the rear knife edge 233 is about 120～150 degree; Front cutting edge 231 is towards the arrival end in reference column hole 221.

Blade 23 usefulness screws 24 pass hole 235 and are fixed on the positioning sleeve 22.

This tool operation using method: the tubing that will exploit inserts the bottom in reference column hole 221, the position of regulating and reserving blade 23, by handle 21 rotation positioning sleeves 22, and tubing applied a spot of axial force, blade 23 just can excise the unnecessary layer in tubing outside gradually, as using the pencil sharpener roll cutting pencil, this instrument can realize shelling the purpose of pipe very like a cork.

Embodiment two:

Fig. 4 shows, compares with embodiment one, and present embodiment has saved handle 21, and two ends all are provided with blade 23, can exploit the tubing of two kinds of different sizes, the same embodiment of all the other structures and principle.
