Abstract

The utility model relates to a novel thin wall pipe cutter which is composed of a body, a head knob, a head thread shaft, an energy storage device, a groove type device, a roller wheel, a lower slide rail, an upper slide rail, a cutter blade, a blade support base, tail knob and a tail thread shaft. For providing proper pressure continuously, the utility model adopts the spring energy storage idea and determines the proper initial energy storage according to theory analysis and practice experience, and the cutter blade automatically feed during the cutting process to realize the purpose of high effective cutting. The novel thin wall pipe cutter has simple and reasonable structure, is economy and practical and ensures the whole operation process to be simple and efficient.

Description

Novel thin-wall pipes cutter

Technical field

The utility model relates to a kind of cutting tool that can cut thin-wall pipes (copper pipe, aluminum pipe).

Background technology

The pipeline cutting technique is widely used in hot-water heating engineering, water supply and sewage work, the electrical installation project, but cutter in the market exists effort time-consuming mostly, shortcomings such as poor operability.

Summary of the invention

The purpose of this utility model is the deficiency at existing cutting tool, a kind of novel cutter that can be used for cutting different thin-wall pipes (copper pipe, aluminum pipe) is provided, advantage part of the present utility model is: the cutter blade feeds automatically in whole cutting process, to reach purpose easy and simple to handle, the time-saving and efficiency, and the thin-wall steel tube distortion after the cutting is less.

The utility model is achieved through the following technical solutions:

A kind of novel thin-wall pipes cutter comprises initial energy storage section, and blade feeds part and main body coupling part.Initial energy storage section is made up of slot-type device, energy storage device, head threads axle and head knob, and wherein, the internal fixation of slot-type device has two rollers, and two ends are made groove and can be slided along slide rail up and down; Energy storage device is made for the compression spring, and the compression spring housing is on the head threads axle; The head threads axle is threaded onto in the endoporus of main body, and an end and slot-type device spin; The head knob is the screw-type knob, and two cylindrical posts that revolve are arranged above.

Said blade feeds part to be made up of cutter blade, blade support, afterbody knob and tailing screw flight axle, and wherein, the cutter blade is fixed in the blade support, can rotate flexibly; Blade support is connected with upper slide rails; The tailing screw flight axle is threaded onto in the endoporus of main body, and an end and blade support spin.

Two endoporus and two slide rails that axial line is identical are arranged on the said main body coupling part, and two slide rails all are placed on the inboard of main body, and upper slide rails is connected with blade support embedding formula with slot-type device, and lower slide rails only is connected with slot-type device, also connect for the embedding formula.

The utlity model has following advantage:

Can successfully finish the Pipe Cutting construction of the multiple thin-wall pipes under different condition, and after using energy storage device, the cutter blade feeds in cutting process automatically, make that the whole operation process is easy, save time, efficiently, and the distortion of the thin-wall steel tube after the cutting is less.The cutter cost is lower, simple in structure, light durable simultaneously.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Wherein: the 1-main body; 2-head knob; 3-head threads axle; The 4-energy storage device; The 5-slot-type device; The 6-roller; The 7-lower slide rails; The 8-upper slide rails; 9-cutter blade; The 10-blade support; 11-afterbody knob; 12-tailing screw flight axle.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the structural representation of the novel thin-wall pipes cutter that proposes in the utility model. include main body, the head knob, the head threads axle, energy storage device, slot-type device, roller, lower slide rails, upper slide rails, the cutter blade, blade support, afterbody knob and tailing screw flight axle. continue to provide convenient pressure in order to reach, by regulating head knob 2 to obtain the primary power of suitable size, tubing is placed between slot-type device 5 and the cutter blade 9, regulate afterbody knob 11 to compress tubing, make slot-type device 5 break away from the about 1mm of initial position, when in a single day slot-type device 5 is compressed the disengaging initial position, initial energy storage promptly is applied on the tubing, cutter is rotated around tubing. in whole cutting process, tubing is cut the have an appointment interior compression deformation of 1mm of position, this process of spring also discharges identical displacement thereupon, in this displacement range, spring can satisfy the needed pressure of cutting to the tubing applied pressure. therefore can reach the purpose of blade auto-feed and efficient cutting.

During the utility model work, at first passing through rotation head knob 2 according to the characteristics of different tubing, is the suitable primary power of energy storage device deposit; Tubing is placed between slot-type device 5 and the cutter blade 9 then, alignment blade need cut off the place, and rotation afterbody knob 11 is until the about 1mm of energy-stored spring retraction; The tubing of then holding with a firm grip makes cutter center on the rotation of tubing axle center, is cut off by cutter until tubing.
