Abstract

The utility model discloses a kind of pipe die mold, including pipe forming portion, the forming cavity internal diameter in pipe forming portion is 321.5mm-322.5mm, and the outside in pipe forming portion is equipped with mould installion hole, mould installion hole along pipe forming portion circumferentially.Mould installion hole is connect with extraneous shackle member, realize that pipe die die location is fixed, in pipe die mold provided by the present application, since the forming cavity internal diameter in pipe forming portion is that 321.5mm-322.5mm processes later half finished diameter and differ smaller with finished diameter when processing the tubing of Φ 320 × 18.5, so that in subsequent fixed process, it need to only process on a small quantity, avoid processing the case where clamping leads to tubing locally ellipticity for a long time, be effectively improved the processing quality of tubing.

Description

Pipe die mold

Technical field

The utility model is related to tubular object extruding technical field, more particularly to a kind of pipe die mold.

Background technology

Thin-wall pipes are usually molded by forging extruding, domestic and international market pair 6061,6063 big specification seamless thin wall tubing Demand is larger.But it is mainly dimensional discrepancy, curvature that the technology of such tubing, which requires, it is much high to cut gradient, presentation quality In GB/T 4437.1.

Wherein, material is 6063T6 alloys, tubing phase before manufacture that specification is Φ 320 × 18.5, using 324 pipe dies of Φ Mold, 285 needle points of Φ carry out tubular object extruding.

However, when pipe die mold processing 320 tubing of Φ of Φ 324, due in cutting process, to tube extrusion, growing Time processing leads to locally ellipticity after tubular object extruding, and the processing quality of tubing is caused to decline.

Therefore, how the processing quality of tubing, be those skilled in the art's technical problem urgently to be resolved hurrily.

Utility model content

The purpose of this utility model is to provide a kind of pipe die mold, to improve the processing quality of tubing.

To achieve the above object, the utility model provides a kind of pipe die mold, including pipe forming portion, the pipe forming The forming cavity internal diameter in portion is 321.5mm-322.5mm, and the outside in the pipe forming portion is equipped with mould installion hole, the mold peace Fill hole along the pipe forming portion circumferentially.

Preferably, the internal diameter in the pipe forming portion is 322mm.

Preferably, further include that tube body guide part is fixedly connected with the pipe forming portion, the tube body guide part is equipped with The tube body directed cavity being connect with the forming cavity transition, the tube body directed cavity are to close to the tapered circle of the molding cavity direction Cone-shaped cavity.

Preferably, the pipe forming portion and the tube body guide part are an integral molding structure.

Preferably, the angle between the side and horizontal plane of the tube body directed cavity is 22 degree of -27 degree.

Preferably, the angle between the side and horizontal plane of the tube body directed cavity is 25 degree.

Preferably, the outer diameter of the pipe die mold is 415mm-420mm.

Preferably, pipe forming portion is 39mm-41mm along the length of tube body axis direction.

In the above-mentioned technical solutions, pipe die mold provided by the utility model includes pipe forming portion, pipe forming portion Forming cavity internal diameter is 321.5mm-322.5mm, and the outside in pipe forming portion is equipped with mould installion hole, mould installion hole along tube body at Type portion is circumferentially.

By foregoing description it is found that when carrying out tubular object extruding, mould installion hole is connect with extraneous shackle member, realizes pipe die Die location is fixed, in pipe die mold provided by the present application, since the forming cavity internal diameter in pipe forming portion is 321.5mm- 322.5mm processes later half finished diameter and differs smaller with finished diameter so that rear when processing the tubing of Φ 320 × 18.5 Continue in fixed process, need to only process on a small quantity, avoids processing the case where clamping leads to tubing locally ellipticity for a long time, have Improve to effect the processing quality of tubing.

Description of the drawings

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is the embodiments of the present invention, for those of ordinary skill in the art, without creative efforts, also Other attached drawings can be obtained according to the attached drawing of offer.

The structural schematic diagram for the pipe die mold that Fig. 1 is provided by the utility model embodiment；

The sectional view for the pipe die mold that Fig. 2 is provided by the utility model embodiment.

In wherein Fig. 1-2：1- pipe formings portion, 2- tube body guide parts.

Specific implementation mode

The core of the utility model is to provide a kind of pipe die mold, to improve the processing quality of tubing.

It is below in conjunction with the accompanying drawings and real in order to make those skilled in the art more fully understand the technical solution of the utility model Applying mode, the utility model is described in further detail.
