Description

A kind of thermal insulation material cutting line knife

Technical field

The utility model is related to thermal insulation material cutting technique fields, more particularly, to a kind of thermal insulation material cutting line knife.

Background technology

Thermal insulation material have developed rapidly, and uses good heat preservation technology and material in industry and building, can often play The effect got twice the result with half the effort.Thermal insulation material is often monoblock in process of production, will be according to required during manufacture or use Formation and size cut.The cutting of present EPS or XPS thermal insulation materials is mostly completed using copper wire, in cutting It needs to heat copper wire, thermal insulation board is melted to the surfacing cut, but cut in this way by the heat of copper wire Property is poor.In addition, the cutting of foam glass is mostly cut using zigzag saw blade, foam glass is cut using saw blade or saw blade When need special mold, it is not only complicated, and saw blade and saw blade can only carry out up and down, left and right movement, for arc The cutting in shape face is difficult to accomplish, flexibility is poor.

Utility model content

The purpose of this utility model is to provide a kind of thermal insulation material cutting line knife, and it is multiple to solve thermal insulation material cutter device structure Problem miscellaneous, flexibility is poor.

To achieve the above object, the utility model provides a kind of thermal insulation material cutting line knife, including core, fixing line and Cutting line, the fixing line are spirally wrapped around the outside of the core, and the cutting line is spirally wrapped around described solid The outside of alignment, the fixing line and the cutting line are the wire of diameter 0.2-0.4mm, and the screw pitch of the fixing line is 8- The screw pitch of 12mm, the cutting line are 0.1-0.5mm.

Preferably, a diameter of 2-3mm of the line knife.

Preferably, the fixing line and the cutting line are steel wire.

Preferably, the core is the steel strand wires being twisted using the steel wire of a diameter of 0.2-0.4mm of 8-15 roots.

A kind of thermal insulation material cutting line knife described in the utility model, core are twisted using 8-15 root steel wires, make line Core has very high intensity, is not susceptible to be broken.The outside of core is spiral to be wound with fixing line, and fixing line is used for core Carry out bundled fixed, it is ensured that cutting line works at higher velocities.It twines the outside of fixing line is spiral It is wound with cutting line, cutting line is the steel wire of diameter 0.2-0.4mm, screw pitch 0.1-0.5mm, and smaller screw pitch can ensure line Cutter has higher cutting force and cutting intensity.

Below by drawings and examples, the technical solution of the utility model is described in further detail.

Specific implementation mode

Embodiment

Fig. 1 is a kind of structural schematic diagram of thermal insulation material cutting line knife embodiment of the utility model.As shown in Figure 1, a kind of Thermal insulation material cutting line knife, including core 1, fixing line 2 and cutting line 3.Core 1 is using a diameter of 0.2-0.4mm of 8-15 roots The steel strand wires that are twisted of steel wire, core 1 is twisted using the steel wire of 10 a diameter of 0.25-0.32mm in the present embodiment Made of.Core 1 plays support in entire line knife, and steel strand wires have higher intensity, it is ensured that core 1 have compared with High intensity extends the service life of core 1, line knife is avoided to be broken in cutting process.

The outside of core 1 is spiral to be wound with fixing line 2, and fixing line 2 is diluter in being externally wrapped with for core 1 It dredges, screw pitch 8-12mm, the present embodiment preferably 10mm.Fixing line 2 has the function of binding and 2 core 1 of fixing line, prevents Core 1 loosens during the work time, it is ensured that line knife works normally under higher cutting speed.Fixing line 2 is straight The steel wire of diameter 0.2-0.4mm, the preferably steel wire of diameter 0.25-0.32mm, fixing line 2 are of the same race with the steel wire inside core 1 Steel wire.

Cutting line 3 is wound with the outside of fixing line 2 is spiral, and cutting line 3 is also the steel of diameter 0.25-0.32mm Silk, cutting line 3 select steel wire of the same race with fixing line 2.The screw pitch of cutting line 3 is 0.1-0.5mm, preferably 0.2-0.3mm, small spiral shell Away from cutting line 3 can improve the intensity and cutting force of cutting line 3, increase the cutting speed of line knife.

A diameter of 2-3mm of entire line knife, line knife, for being cut to thermal insulation material, are being cut on numerical control device It need not heat in the process, and cut direction flexibility is high, equipment is simple, can complete variously-shaped thermal insulation material Cutting.

Therefore, the thermal insulation material cutting line knife of the utility model using the above structure can solve thermal insulation material cutting dress Problem complicated, that flexibility is poor is set, has the advantages that cutting speed is fast.

It is specific embodiment of the present utility model above, but the scope of protection of the utility model should not be limited to thoses mentioned above.Appoint What those skilled in the art is in the technical scope disclosed by the utility model, the change or replacement that can be readily occurred in, It should be covered within the scope of the utility model, therefore the scope of protection of the utility model should be limited with claims Subject to fixed protection domain.
