Description

Concave die for manufacturing elbow shell of heat-insulating pipe

Technical Field

The utility model belongs to the field of dies, and particularly relates to a female die for manufacturing an elbow shell of a heat-preservation pipe.

Background

In many fields of China, such as chemical industry, oil refining and building fields, a plurality of pipelines need heat preservation treatment to normally transmit gas or liquid. Usually, heat insulation materials such as heat insulation cotton are wrapped outside the transportation pipeline, and the outer layer of the heat insulation material needs to be fixed with a shell to fix the heat insulation material and prolong the service life of the heat insulation pipe. The commonly used heat preservation pipe shell is usually cylindrical and is directly sleeved outside the heat preservation material, the elbow of the heat preservation pipe is also fixed by mutually nesting a multi-petal type cylindrical structure, and in reality, a plurality of pipelines are complex in bending and complex in structure, and the heat preservation of the transportation pipeline can be fixed by a considerable number of multi-petal type cylindrical shells. Meanwhile, the multi-petal type cylindrical shell is sequentially nested and installed on an installation site, so that the operation is complex, time and labor are wasted, high-efficiency work cannot be guaranteed, and the production efficiency is greatly reduced.

Disclosure of Invention

The technical problem to be solved by the utility model is as follows: the defects of the prior art are overcome, the female die for manufacturing the heat-preservation pipe elbow shell is provided, the structure is simple, and the installation efficiency of the heat-preservation pipe shell can be improved.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a preparation heat preservation elbow shell's die, includes the mould body, its characterized in that: an arc-shaped groove is formed in the die body, and the angle between the starting end and the ending end of the groove is 90 degrees; the section of the inner wall of the groove is an arc surface, the upper end surface of the groove is higher than the center of the arc surface, and at least three reinforcing rib grooves are uniformly distributed at the bottom of the groove; the grooves close to the starting end and the ending end are respectively provided with a fixed strip groove, the inner side and the outer side of the groove between the two fixed strip grooves are respectively provided with a fixed arc groove, and the fixed arc grooves are close to the upper end face of the groove.

Further, the depth of the fixed strip groove is the same as that of the fixed arc groove.

Furthermore, two fixed arc grooves which are distributed up and down are respectively arranged on the inner side and the outer side of the groove between the two fixed strip grooves.

Furthermore, 5 reinforcing rib grooves are uniformly distributed at the bottom of the groove.

Compared with the prior art, the utility model has the beneficial effects that:

1. the shells manufactured by the utility model can be mutually buckled into a complete heat-insulation bent pipe shell, and only the shells are clamped and fixed by the fastening piece during installation, so that the operation is convenient, the raw materials are saved, and the installation efficiency is greatly improved.

2. The upper end surface of the groove is higher than the circle center of the arc surface, the shells manufactured in the way are overlapped and buckled with each other pairwise, the two shells are convenient to match and position, the strength of the interface of the two shells is enhanced, the appearance is attractive, the water is prevented, and the service life of the heat preservation pipe is prolonged.

3. Five reinforcing rib grooves are uniformly distributed at the bottom of the groove, so that the stress of the bent part can be effectively eliminated, the produced bent pipe shell is ensured to be more smooth, and the installation and heat preservation effects are better.

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic sectional view taken along line a-a in fig. 1.

Labeled as:

1. a mold body; 2. a groove; 3. a reinforcing rib groove; 4. fixing the strip groove; 5. and fixing the arc groove.

Detailed Description

In the utility model, the direction of the center of an arc in the die body is taken as the inner side, and the direction is taken as the outer side otherwise.

The utility model will be further described with reference to the following examples:

as shown in fig. 1 and 2, the utility model provides a female die for manufacturing a shell of an elbow of a thermal insulation pipe, which comprises a die body 1, wherein an arc-shaped groove 2 is formed in the die body 1, and an angle between a starting end and an ending end of the groove 2 is 90 degrees. The cross section of the inner wall of the groove 2 is an arc surface, and the upper end surface of the groove 2 is higher than the circle center of the arc surface, so that the manufactured elbow shell has overlapping edges which can be overlapped with each other, and the strength of the joint between the elbow shell and the manufactured elbow shell is enhanced. The bottom of the groove 2 is uniformly provided with at least three reinforcing rib grooves 3, the bottom of the groove 2 is uniformly provided with five reinforcing rib grooves 3, the reinforcing rib grooves 3 can effectively decompose the stress generated in the bending forming process of the shell, and the formed shell is prevented from being bent and tilted. The groove 2 close to the starting end and the ending end is provided with a fixed strip groove 4, the inner side of the groove 2 between the two fixed strip grooves 4 and the outer side of the groove 2 are provided with a fixed arc groove 5 respectively, in the embodiment, the number of the fixed arc grooves 5 is two distributed from top to bottom, and the fixed arc grooves 5 are close to the upper end face of the groove 2. The depth of the fixed strip groove 4 is the same as that of the fixed arc groove 5, so that the shell can be well positioned when the two shells are buckled, and the installation efficiency and quality are improved.

When the shell of the heat-insulating pipe elbow is produced, a shell material is firstly laid in the female die, a rubber hammer is utilized to hammer and press the shell into a half shell of the heat-insulating pipe, and the two shells are buckled and fixed by utilizing a hoop or a screw or a hasp and the like during installation, so that the installation convenience is greatly improved.

The forming process of the shell is the prior art and is not described in detail.

The foregoing is directed to preferred embodiments of the present invention, other and further embodiments of the utility model may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
