Abstract

The utility model discloses a pipe pressing die, which comprises an oblong upper die, an oblong lower die and an inner core shaft, wherein the upper die is axially provided with a semi-cylindrical hole, the lower die is axially provided with a semi-cylindrical hole, and a plurality of strip lug bosses are uniformly distributed in each of the upper die and the lower die section by section; and a plurality of strip grooves are oppositely uniformly distributed on the inner core shaft section by section. The pipe pressing die can be pressed on a metal pipe and stretched into a strip concave-convex table section by section, and the strength of the pressed metal pipe can be enhanced; when the metal pipe is used for transferring heat energy, the heat exchange area can be enlarged; when the metal pipe is used for delivering heat energy by using liquid, turbulence for self cleaning is formed; and when the fluid flows in the pipe, intensive stirring is produced due to the action of the concave-convex strip, so that the fluid can reach full turbulence, scales are not formed in the pipe, and the flow is quick and fast.

Description

Press pipe mold

Technical field

The utility model relates to a kind of mould, refers more particularly to a kind of pressure pipe mold.

Background technology

Existing thin-wall metal pipe kind is more on the market; The thin-wall metal pipe bearing capacity that is used on radiator and the heat exchanger product mainly leans on the tube wall thickness to depend on withstand voltage degree; Under normal strong attitude, use out of question such as intended diameter 76*1 radiating tube; Once run into pipeline backwater fault, and possibly vacuumize the pipe distortion, make troubles to the user.

Summary of the invention

The purpose of the utility model provides a kind of pressure pipe mold; Under equal design condition, overcome the above-mentioned defective of prior art, increase body intensity, and form the turbulent flow of flow of liquid when defeated; Pipe is from clean in making, and cost is low, stable performance, heat conductive efficiency are high, easy to use.

For realizing above-mentioned purpose, the technical scheme of the utility model is:

A kind of pressure pipe mold comprises: upper die and lower die and inner spindle, patrix axially have semicylindrical opening, and counterdie axially has semicylindrical opening, it is characterized in that: be provided with rectangular boss in the said patrix, be provided with rectangular boss in the counterdie; Correspondence is provided with rectangular groove on the said inner spindle.

According to described pressure pipe mold, it is characterized in that: said patrix is a rectangle, and said counterdie is a rectangle, in the upper die and lower die semicylindrical opening respectively segmentation be evenly equipped with a plurality of rectangular boss; Corresponding segments is evenly equipped with a plurality of rectangular grooves on the said inner spindle.

The beneficial effect of the utility model:

1, the metal body after the compacting can strengthen its intensity;

2, when the metal tube body is used for the heat energy transmission, can increase heat exchange area;

3, the metal tube body is used for the heat energy fluid transfer, and it is self-cleaning to form turbulent flow, when fluid flows in body, because concavo-convex effect produces strong stirring, thereby can make fluid reach sufficient turbulent flow, does not tie dirt in the pipe, and flow is rapid, quick.

In the accompanying drawing: 1, patrix; 2, semicylindrical opening; 3, counterdie; 4, rectangular boss; 5, rectangular groove; 6, inner spindle; 7, the pipe of compacting; 8, the rectangular groove of suppressing on the pipe.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:

The utility model pressure pipe mold such as Fig. 1, Fig. 2, shown in Figure 3 comprise: patrix 1, counterdie 3 and inner spindle 6, and patrix 1 axially has semicylindrical opening 2, and counterdie 3 axially has semicylindrical opening 2, is provided with rectangular boss 4 in the patrix 1, is provided with rectangular boss 4 in the counterdie 3; Correspondence is provided with rectangular groove 5 on the inner spindle 6.Patrix 1, counterdie 3 are rectangle, in patrix 1 and counterdie 3 semicylindrical openings respectively segmentation be evenly equipped with a plurality of rectangular boss 4; Corresponding segments is evenly equipped with a plurality of rectangular grooves 5 on the inner spindle 6.

The utility model presses pipe mold to be made up of upper die and lower die, can be compressed on the metal body, and segmentation is stretched as concavo-convex of elongate in shape, and the metal body after the compacting can strengthen its intensity; When the metal tube body is used for the heat energy transmission, can increase heat exchange area; The metal tube body is used for the heat energy fluid transfer, and it is self-cleaning to form turbulent flow, when fluid flows in body, because concavo-convex effect produces strong stirring, thereby can make fluid reach sufficient turbulent flow, does not tie dirt in the pipe, and flow is rapid, quick.

The utility model operational process of craft: the rectangle counterdie is fixed on the press bench face; The rectangle patrix is fixed on forcing press work upper table surface, and segmentation is uniformly distributed with rectangular groove inner spindle one end connection and has on the spring support, and the other end is a charging aperture; Pipe fitting is suppressed top and bottom for the first time; When suppressing for the second time, the extraction pipe fitting revolves to turn 90 degrees and inserts inner spindle compacting top and bottom, and pipe fitting has formed multiple-grooved.

Embodiment recited above describes the preferred implementation of the utility model; Be not that design and protection domain to the utility model limits; Under the prerequisite that does not break away from the utility model design concept; Common engineers and technicians make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection domain of the utility model.
