Description

Apparatus for manufacturing corrugated pipes

The present invention relates to a corrugated pipe manufacturing apparatus used for underground burial, more specifically, the semi-melt synthetic straight pipe is continuously moved through the inlet side of the fixed plate fixed to both sides of the reciprocating plate The primary molding is performed by the reciprocating motion of the first mold installed inside, followed by the secondary molding by the reciprocating motion and the conveying motion of the second mold and cooling by the water jacket at the same time. The present invention relates to a corgate manufacturing apparatus that can improve the forming speed of a corgate tube drawn out through and can produce a corgate tube regardless of diameter by simple replacement of a mold and a size sizing.

In general, CORRUGATED PIPE, which is buried in the ground during construction or civil engineering, is used for various purposes such as various water pipes, sewage pipes, sewage pipes, and drainage pipes, has an outer circumferential surface and a smooth inner circumferential surface. Because of its double wall structure, it has excellent strength against external pressure such as earth pressure and lubrication pressure, and it is widely used for water and sewage construction because of its flexibility and elasticity.

In addition, since the inner circumferential surface of the corgate tube is smoothly formed, the water passage efficiency is high, and thus the flow rate and flow rate are superior to those of other longitudinal tubes.

Since various manufacturing apparatuses for manufacturing the corgate tube have been devised and used, the size of the conventional manufacturing apparatus is inevitably large due to a relatively large diameter of 10 cm to 2 m. Excessive facility investment and space securing for the facility had a problem.

Figure 1 is a view showing a general form of a conventional corgate tube manufacturing apparatus based on the above Figure Looking at the simple structure of the conventional corgate tube manufacturing apparatus as follows.

First, Figure 1 is a schematic perspective view of a conventional corgate tube manufacturing apparatus, as shown in the conventional corgate tube manufacturing apparatus 10 is semicircular to one side on a rectangular support plate 12 formed with a transfer groove 11 It takes the structure which consists of many mold 13 in which the corgate tube shaping part 13a of this is formed.

The conveying groove 11 formed on the support plate 12 of the corgate tube manufacturing apparatus 10 is formed on the support plate 12 and a central conveying groove (not shown) passing through the center of the support plate 12. It is divided into a rapid feed groove that is responsible for the outer transfer of 13).

On the other hand, the mold 13 has a corgate tube forming part 13a formed in a semicircular shape at one side thereof, and a plurality of grooves having the same shape as the outer circumferential surface of the corgate tube in the inner side of the corgate tube forming part 13a. 13b) is provided.

In the conventional corgate tube manufacturing apparatus 10 having the structure as described above, a plurality of molds 13 are sequentially moved along the transfer grooves 11 formed on the support plate 12 to produce corgate tubes. In this case, while the mold 13 is moved from the rapid feed groove formed on both sides of the support plate 12 to the central feed groove, the semi-circular corgate tube forming portion 13a abuts against each other and is in contact with the circular corgate tube. The shaping | molding part 14 is comprised.

The synthetic corrugated pipe of the semi-melt state is positioned in the circular corgate tube forming portion 14, and since the synthetic straight pipe is continuously supplied from the supply passage, the mold 15 on the central conveying groove is supplied at a speed of supplying the synthetic resin straight pipe. It moves forward along the center feed groove at the same speed as.

In this way, the synthetic resin straight pipe moving forward on the center transfer groove together with the mold 15 is formed into a corgate tube having a double wall by the corgate tube forming part 13a of the mold 15 during the movement thereof. The mold 15 moved to the end of is separated to both sides to achieve a rapid feed back in place along the rapid feed groove around.

As such, the conventional corgate tube manufacturing apparatus 10 has a large number of molds 13 forming a single line along the conveying groove 11 of the support plate 12, so that the scale of the manufacturing apparatus is inevitably increased. It is pointed out that the transfer distance of the mold 13 which flows along the transfer groove 11 is long, thus requiring an additional mechanical device.

In addition, since the mold 15 is simultaneously transported in the longitudinal direction of the corgate tube to be manufactured, the conventional corgate tube manufacturing apparatus 10 is coupled to the mold 15, that is, the corgate tube on the outer circumferential surface of the synthetic resin straight tube. In the process of forming the uneven surface by the groove 13b formed in the corgate tube forming portion 14, the portion where the neighboring mold 15 on the longitudinal uneven surface abuts may be formed at regular intervals in the horizontal or vertical direction. There is only a problem.

Therefore, the present invention was devised to solve the above-mentioned shortcomings and problems pointed out in the conventional corgate tube manufacturing apparatus, and the fixing plate of the corgate tube inlet side and the outlet side of the corgate tube manufacturing apparatus is coupled to the frame. And a reciprocating plate is placed inside the fixed plates on both sides to form a periodic reciprocating motion, and the first mold repeats the reciprocating motion and the conveying motion inside the reciprocating plate on the corgate tube moving passage passing through the inlet hole and the outlet hole of the fixed plate. And the second mold is installed so that the synthetic resin straight pipe passing therebetween is made so that the corgate tube can be manufactured, so that the equipment of the corgate tube manufacturing apparatus can be configured to a minimum size so that it can be installed in a small space. Water jacket is installed inside the mold divided into two molds and cooling simultaneously Lies in a so as to improve the speed of forming the gate cor By tube to occur is an object of the devise.
