Description

Forming die for elbow heat-insulation cotton

Technical Field

The utility model belongs to the technical field of heat preservation pipes, and particularly relates to a forming die for elbow heat preservation cotton.

Background

The heat insulation pipe is a short name of heat insulation pipeline, is used for conveying liquid, gas and other media, and is widely applied to heat insulation of pipelines of petroleum, chemical engineering, aerospace, military, central heating, municipal administration and the like. The heat preservation pipe is usually composed of an internal conveying pipe, heat preservation cotton and a shell, and in the actual installation and use process, the heat preservation sleeve of the straight pipe is formed by wrapping heat preservation materials on the straight pipe, baking the straight pipe to enable the straight pipe to be solidified, and then dividing the straight pipe into two parts to be assembled and fixed on site. When the elbow insulating pipe needs to be wrapped with the insulating sleeve, the straight pipe insulating sleeve is cut into horseshoe-shaped thin blocks by adopting an inclined surface cutting method in the prior art, and then the elbow insulating sleeve is assembled on site. The method has high operation requirements on workers and high rejection rate, thereby causing a great deal of waste of raw materials, and having complex processing and low work efficiency; meanwhile, due to the fact that a plurality of blocks are spliced, the number of spliced seams is large, the heat insulation performance of the bent pipe is seriously affected, and the heat insulation performance is 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 forming die for the elbow heat-insulation cotton is provided, the processing efficiency can be improved, the material loss is reduced, and the heat-insulation performance is improved.

The technical scheme adopted by the utility model for solving the technical problems is as follows: a forming die for elbow heat-preservation cotton comprises a die body, wherein the die body comprises a female die and a male die, an arc-shaped groove is formed in the female die, a 90-degree included angle is formed between the starting end and the finishing end of the groove, the cross section of the inner wall of the groove is a combined surface of a semi-arc surface and a vertical surface, the upper part of the cross section is the vertical surface, the lower part of the cross section is a semi-arc surface, and the vertical surface is connected with the semi-arc surface; the male die and the female die are arranged oppositely, and a specific gap is arranged between the male die and the female die.

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

1. according to the utility model, the elbow heat-insulation cotton is manufactured in a mode of a female die and a male die, when the elbow heat-insulation cotton is used, only two pieces of heat-insulation cotton are buckled on the conveying bent pipe in a butt joint mode, and the outside of the elbow heat-insulation cotton is fixed by the shell, so that the production efficiency can be greatly improved, and meanwhile, the material is hardly lost.

2. According to the utility model, the cross section of the inner wall of the groove is a combined surface of the semicircular arc surface and the vertical surface, the upper part of the cross section is the vertical surface, the lower part of the cross section is the semicircular arc surface, and the vertical surface is connected with the semicircular arc surface, so that the upper end surface of the groove is higher than the circle center of the semicircular arc surface, and during actual installation, the raised parts are overlapped together, so that no splicing gap exists between two pieces of heat preservation cotton, and the heat preservation performance of the bent pipe part is effectively ensured.

FIG. 2 is a schematic sectional view taken along line A-A in FIG. 1;

fig. 3 is an enlarged schematic view of a portion I in fig. 2.

Labeled as:

1. a female die; 2. a male die.3. a groove; 4. a semi-circular arc surface; 5. a vertical plane.

Detailed Description

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

as shown in fig. 1-2, the utility model provides a forming die for elbow heat-preservation cotton, which comprises a die body, wherein the die body comprises a female die 1 and a male die 2, an arc-shaped groove 3 is formed in the female die 1, and an included angle of 90 degrees is formed between the starting end and the ending end of the groove 3. The cross section of the inner wall of the groove 3 is a combined surface of a semi-circular arc surface 4 and a vertical surface 5, the upper part of the cross section is the vertical surface 5, the lower part of the cross section is the semi-circular arc surface 4, and the vertical surface 5 is connected with the semi-circular arc surface 4. The male die 2 and the female die 1 are arranged oppositely, and a specific gap is formed between the male die 2 and the female die 1. In order to ensure the strength of the die, the die body is made of metal.

The steps of producing the elbow heat-preservation cotton by using the mould are as follows:

(1) laying a heat-insulating material in the female die 1;

(2) placing the male die 2 in the female die 1, and pressing the heat-insulating material tightly;

(3) sending the die body into an oven for baking at the baking temperature of 600 +/-50 ℃;

(4) and taking out the mold body, and demolding to obtain the elbow heat-preservation cotton.

The elbow heat preservation cotton of so making, when in actual use, only need two liang of buckleing in return bend department, the skin add the shell fixed can, simple to operate, thermal insulation performance is good.

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. However, any simple modification, equivalent change and modification of the above embodiments according to the technical spirit of the present invention may be made without departing from the technical spirit of the present invention.
