Abstract

The utility model relates to one kind to be convenient for thin-wall copper pipe end cutting die head, including pipe fitting ontology, the pipe fitting ontology includes socket end and positive stop end, the tube wall of the socket end is equipped with multiple axial gaps, multiple axial gaps are centered on the axis of the pipe fitting ontology, tube wall annular along the pipe fitting ontology is uniformly distributed, and the tube wall periphery of the socket end is equipped with multiple annular grooves；Reduce the deflection of copper pipe terminal, convenient for the segmentation cutting of subsequent copper pipe.

Description

One kind using die head convenient for the cutting of thin-wall copper pipe end

Technical field

The utility model relates to one kind to be convenient for thin-wall copper pipe end cutting die head.

Background technique

In the prior art, copper pipe is usually a root long pipe when production, when in use, is needed copper pipe cutting section；Wall thickness Relatively thin (1-2mm) is relatively large in diameter in the copper pipe transportational process (greater than 100mm), and the end of copper pipe is very easy to deformation, is carrying out Before copper pipe cutting section, it usually needs first cut away the end of copper pipe, the length cut away, depending on deformation length； Using conventional method, when cutting to thin-wall copper pipe end, copper pipe terminal is easily deformed, even if original end is cut Fall, the new end of formation is still the substandard product of deformation.

Utility model content

The utility model in view of the deficiency of the prior art, provides a kind of convenient for thin-wall copper pipe end cutting mould Head.

The technical solution that the utility model solves above-mentioned technical problem is as follows: one kind using mould convenient for the cutting of thin-wall copper pipe end Head, including pipe fitting ontology, the pipe fitting ontology include socket end and positive stop end, and the tube wall of the socket end is equipped with multiple axial directions Notch, for multiple axial gaps centered on the axis of the pipe fitting ontology, the tube wall annular along the pipe fitting ontology is uniformly distributed, And the tube wall periphery of the socket end is equipped with multiple annular grooves.

The beneficial effect of die head is: for being socketed in the end of thin-wall copper pipe, then being cut again, reduces copper pipe terminal Deflection, convenient for subsequent copper pipe segmentation cutting.

Further, the annular groove is V-groove.

Beneficial effect using above-mentioned further technical solution is: the blade of V-groove and cutter is adapted, and guarantees copper pipe end Head cutting is more neat.

Further, annular protrusion is equipped on the inside of the tube wall of the positive stop end.

Beneficial effect using above-mentioned further technical solution is: playing position-limiting action to copper pipe terminal, it is ensured that cutting length The accuracy of degree.

Further, graduation mark is equipped at each annular groove.

Detailed description of the invention

Fig. 1 is the three dimensional structure diagram of die head in the utility model；

Fig. 2 is the schematic diagram of the section structure of die head in the utility model；

Status diagram when Fig. 3 is thin-wall copper pipe end cutting in the utility model；

In the accompanying drawings, list of designations represented by each label is as follows: 1, pipe fitting ontology, 1-1, socket end, 1-11, axis To notch, 1-12, annular groove, 1-2, positive stop end, 1-21, annular protrusion, 2, copper pipe, 3, cutter.

Specific embodiment

The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical It is novel, it is not intended to limit the scope of the utility model.

As Figure 1-Figure 2, a kind of convenient for the cutting of thin-wall copper pipe end die head, including pipe fitting ontology 1, the pipe fitting sheet Body 1 is equipped with multiple axial gap 1-11, Duo Gesuo including the tube wall of socket end 1-1 and positive stop end 1-2, the socket end 1-1 Axial gap 1-11 is stated centered on the axis of the pipe fitting ontology 1, the tube wall annular along the pipe fitting ontology 1 is uniformly distributed, and institute The tube wall periphery for stating socket end 1-1 is equipped with multiple annular groove 1-12, and the annular groove 1-12 is V-groove.

Annular protrusion 1-21 is equipped on the inside of the tube wall of the positive stop end 1-2.

Graduation mark is equipped at each annular groove 1-12.

As shown in figure 3, the utility model further relates to a kind of cutting method of thin-wall copper pipe, thin wall type copper is convenient for using above-mentioned Pipe end cutting die head,

Firstly, first the socket end of the die head is socketed in described thin before the end to thin-wall copper pipe 2 is cut On the end of wall copper pipe 2, so that the end of thin-wall copper pipe 2 contradicts the annular protrusion 1-21 on the inside of positive stop end 1-2 tube wall；

Then, further according to demand, cutter 3 is directed at the annular groove 1-12 on corresponding graduation mark, to die head and thin wall type copper It is cut the end of pipe 2.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
