Abstract

The invention discloses a shaping mold of a helical structure. The shaping mold of a helical structure comprises a first shaping part and a second shaping part. The first shaping part is arranged at a front part of the second shaping part and comprises a first plum blossom-shaped through hole. The second shaping part comprises a second plum blossom-shaped through hole. The first shaping part is used for preliminary shaping. The second shaping part is used for stress restoration shaping of a tube after the preliminary shaping. In shaping, a tube rotates at a certain rotation speed. Through the shaping mold of a helical structure, a tube of which inner and outer walls have helical structures is obtained.

Description

A kind of shaper of helical structure

Technical field

The present invention relates to a kind of shaper, the inside and outside wall that refers in particular to a kind of tube all is the shaper of the helical structure of quincunx helical structure, belongs to the shaper technical field of tube.

Background technology

Generally, be provided with circular port in the tube, its inwall all is smooth, and when this tube was used for the water conservancy diversion fluid, under uniform pressure, flow velocity was slow, and sense of direction is poor; In order to reach the flow velocity of expection, adopt the method that increases pressure to realize that this will inevitably cause the increase of energy consumption usually, press for for this reason and developed a kind of new tube, the inside and outside wall of said new tube all is quincunx helical structure; In order to produce this new tube, we have developed a kind of shaper of helical structure.

Summary of the invention

The present invention seeks to provide a kind of inside and outside wall of tube all to be the shaper of the helical structure of quincunx helical structure for the deficiency that overcomes prior art.

For achieving the above object, the technical scheme that the present invention adopts is: a kind of shaper of helical structure comprises first setting section, second setting section; Said first setting section is arranged on the front portion of second setting section; Said first setting section comprises the first setting section housing, the first setting section cavity, the first typing matrix; The said first setting section cavity is arranged on the inside of the first setting section housing, forms a passage; The said first typing matrix has a plurality of, is spaced apart and arranged in the first setting section cavity; The said first typing matrix comprises the first typing matrix body, the first quincunx through hole, first chute; The said first quincunx through hole is arranged on the center of the first typing matrix body; Said first chute has a plurality of, is arranged on equably on the excircle of the first typing matrix body; The excircle of the first typing matrix body of said each first typing matrix can be along first chute being arranged in the first setting section cavity rotatably; Said second setting section comprises typing bar, the second typing matrix, the said second typing matrix, comprises the second typing matrix body, the second quincunx through hole, second chute; The said second typing matrix body is rounded; The said second quincunx through hole is arranged on the center of the second typing matrix body; Said second chute has a plurality of, is arranged on the periphery of the second typing matrix body equably along the circumferencial direction of the second typing matrix body; The said second typing matrix has a plurality of, and is arranged at interval on the typing bar; Said typing bar has many, and every typing bar passes second chute of every second typing diaphragm.

Preferably, said every second typing diaphragm is provided with 4 second chutes, and said typing bar has 4; Said every typing bar passes the second corresponding chute on the every second typing matrix body; The said multi-disc second typing matrix body forms the helical form setting.

Because the utilization of technique scheme, the present invention compared with prior art has advantage:

The shaper of the present invention program's helical structure comprises first setting section, second setting section; Said first setting section is arranged on the front portion of second setting section; Said first setting section is used for tentatively finalizing the design; The stress of the tube after the second typing cloth is used for tentatively finalizing the design recovers typing; In the type-approval process, tube is with the rotation of certain rotary speed, after the shaper typing through helical structure of the present invention, promptly can be made into all tubes of structure in the shape of a spiral of inside and outside wall.
