Description

Template and method for sealing pipe opening

Technical Field

The invention belongs to the field of pipe fitting machining, and particularly relates to a template and a method for sealing an opening of a pipe fitting, which can improve the working efficiency and the working quality.

Background

The known pipe opening sealing method is that the pipes are fed into a sealing machine one by one, then the sealing machine is aligned with the opening of the pipe to heat, so that the material of the opening flows after melting to cover the opening, then the material is condensed to complete the sealing of the opening, and finally the pipe after sealing is moved out of the sealing machine, and the next section of working flow can be carried out.

The pipe opening sealing construction method is a simple and easy-to-form technology, so that the working requirement can be successfully met only by controlling the working temperature and the sealing shape, and a good pipe finished product is obtained. The control of temperature and shape is a technique that can easily meet the requirements of the prior art, and is not difficult in practice.

However, the operation mode of sealing by using a single pipe fitting is not good in working efficiency, is not suitable for mass production, and increases working cost; and when each pipe fitting is sealed, the temperature and the pressure of each pipe fitting can have slight errors, and when the working times are increased, the error amount is also increased, so that the quality of the product is uneven, and the practicability is influenced.

Therefore, the effective pipe opening sealing method adopts a working mode of simultaneously sealing a plurality of pipes, and comprises the steps of firstly preparing an operation platform, arranging and fixing the plurality of pipes on the operation platform, then obtaining a template for heating, contacting the heated template with the pipe openings of the plurality of pipes, and continuously pressurizing to complete the sealing operation of the pipe openings.

However, although the above-mentioned methods for operating a plurality of pipes are more efficient, there are still disadvantages to be improved because the size of the operation platform is limited in consideration of the convenience of operation, the arrangement density of the plurality of pipes thereon must be relaxed, the distance between the pipes should not be too small, the sealing operation must be performed to heat and melt the pipe opening, if the distance between adjacent pipes is too short, it is likely that two pipes are accidentally bonded during operation, a small amount of pipes are lost, and the operation is interrupted to the greatest extent, which affects the whole process.

Therefore, although the working method of the plurality of pipes is better than the sealing of a single pipe, the efficiency is not easy to show due to the small number of pipes sealed at one time; if the range of the work platform is expanded, the configuration of the fixture and the whole production line must be redesigned in order to take and place the pipe fittings in a large range at a time, which may greatly increase the cost and make the yield difficult to control.

In view of the above, the foregoing method is obviously not an excellent method for improving the sealing of the opening of the pipe, and it is necessary to find other suitable techniques for obtaining the best working result.

Therefore, the inventor considers the deficiency of the prior art, and proceeds to improve, and follows the requirement of pursuing the product with the best quality, and by means of the professional knowledge and practical experience in the industry for many years, through long-term research and development and implementation, the template and the method for sealing the opening of the pipe fitting can be completed.

Disclosure of Invention

The invention mainly aims to provide a template and a method for sealing pipe openings, which greatly increase the sealing operation of pipe openings in unit area quantity, further improve the whole working efficiency and reduce the working cost.

Another objective of the present invention is to provide a template and a method for sealing openings of pipe fittings, which further improve the production yield, so that each pipe fitting can maintain good quality, and increase the market competitiveness.

The template for sealing the opening of the pipe fitting comprises a template, wherein the surface of the template is provided with at least three mold cavities which are arranged in a regular triangle, and a separating needle is convexly extended at the center of the regular triangle formed by the three mold cavities.

By the design of the isolating needle, when the template seals the opening of the pipe, the pipe materials near the opening can be melted, at the moment, due to the design of the isolating needle, the adjacent pipes cannot be contacted, the shortest distance can be kept between any two adjacent pipes, the pipe with the largest sealing amount can be simultaneously sealed in the working range of each template, and the working efficiency can be improved.

The working steps of the structure are that firstly, the pipe fittings with the same number with the die cavities in the template are arranged in a regular triangle;

then, heating the mold cavity;

aligning the template above the pipe fitting to align the mold cavities with the corresponding pipe fittings, and pressurizing the template to melt the openings of the mold cavities for sealing;

finally, the template is removed and the opening is allowed to cool to complete the seal.

Furthermore, when the mold cavity is heated, the temperature inside the mold cavity can be higher than the temperature of the opening end of the mold cavity, so that the pipe can be heated only preliminarily without melting when entering the opening end of the mold cavity, and the opening temperature can be immediately melted to form a seal after the opening of the pipe is completely inserted into the mold cavity.

To speed up the process, the heated platen is removed after the opening is heat sealed and formed, and the pipe is then covered with another cooling platen of the same construction but not heated to speed up the cooling.

The cooling template for cooling is cooled and frozen to reduce the temperature before working.

Preferably, the number of the mold cavities and the number of the fitting tubes are more than three and arranged in a plurality of regular triangles, and the mold plate is provided with a partitioning needle protruding from the center of each regular triangle, so that the partitioning needles can be arranged between all the mold cavities for partitioning.

Preferably, the mold cavities and the fitting tubes are arranged in regular hexagons formed by combining a plurality of regular triangles, because the regular hexagons can arrange the maximum number of mold cavities in a limited space.

In addition, the mold cavity is hemispherical, so that the opening is guided by the mold cavity to be formed inwards in a centralized manner after being melted, and the opening cannot flow out of the mold cavity, thereby maintaining the stability of the appearance.

The mold cavity is drilled, and the separating needle is formed by naturally collecting waste materials generated during drilling, so that the production is quite easy.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The following describes in detail a specific embodiment of a template and a method for sealing an opening of a pipe according to an embodiment of the present invention with reference to the accompanying drawings.

Referring to fig. 1 to 3, the present invention mainly provides a template for sealing an opening of a pipe, which includes a template 1, wherein the surface of the template 1 is provided with at least three mold cavities 2, so that each mold cavity 2 is sealed with respect to an opening 41 of a pipe 4.

The three mold cavities 2 are arranged in a regular triangle and are characterized in that the distances among the mold cavities 2 are equal; the template 1 is protruded with a partition pin 3 at the center of the regular triangle formed by the three cavities 2, and the purpose of the partition pin 3 is to block the adjacent tubes 4 to ensure that the adjacent tubes 4 do not contact each other when sealing the opening 41.

With the foregoing structure, the advantages of the present invention can be clearly seen. When the template 1 seals the opening 41 of the pipe 4, the material of the pipe 4 near the opening 41 is melted, and at this time, due to the design of the partition pin 3, the adjacent pipes 4 are not contacted, so that the opening 41 can be sealed and the work can be finished by cooling respectively. Therefore, the shortest distance can be kept between any two adjacent pipes 4, so that the pipes 4 with the most sealing can be simultaneously sealed in the working range of each template 1, the working efficiency can be improved, and the occurrence of errors can be reduced.

Referring to fig. 3 to fig. 6, with the above structure, the implementation steps of the present invention are summarized as follows:

61. arranging the pipe fittings 4 with the same number as the die cavities 2 in the template 1 in a regular triangle;

62. heating the mold cavity 2 to a temperature capable of melting the material of the pipe fitting 4 for molding;

63. aligning the template 1 above the pipe 4, aligning the mold cavities 2 with the corresponding pipe 4 for sleeving, and then pressurizing the template 1 to melt the opening 41 of the mold cavity 2 for sealing, wherein in the sealing process, due to the separation of the separation needle 3, the adjacent pipes 4 are not contacted with each other even if being pressed, so that the pipes 4 can be sealed independently, and the accidents of mutual contact entanglement and even sticking can not occur;

64. the template 1 is removed and the opening 41 is allowed to cool to complete the seal.

When the mold cavity 2 is heated, the temperature inside the mold cavity 2 is higher than the temperature of the mold cavity opening end 21, so that when the pipe 4 enters the mold cavity opening end 21, only the preliminary heating is performed without melting, and after the opening 41 of the pipe 4 is completely inserted into the mold cavity 2, the temperature of the opening 41 can be immediately melted to form a seal, so that the whole sealing operation can be more smooth, and the formed pipe 4 can be more beautiful.

After the opening 41 is heat sealed and formed in step 63, the heated platen 1 is removed and the pipe 4 is covered with another cooling platen (not shown) of the same construction but not heated, thereby speeding up cooling and increasing work throughput

Of course, the cooling template for cooling is cooled and frozen to reduce the temperature before operation.

In addition, the number of the mold cavities 2 and the number of the matched pipe fittings 4 are more than three and arranged in a plurality of regular triangle arrangement, and the mold plate is provided with a separating needle 3 protruding from the center of each regular triangle, so that the separating needles 3 can be arranged among all the mold cavities 2 for separation.

In fact, the mold cavity 2 and the fitting tube 4 are preferably arranged in a regular hexagon formed by combining a plurality of regular triangles, because the regular hexagon can arrange the maximum number of mold cavities 2 in a limited space, as if the honeycomb structure is stable.

The mold cavity 2 is a hemispherical shape, so that the opening 41 is guided by the mold cavity 2 to be formed inward after melting, and will not flow out of the mold cavity 2, thereby maintaining the stability of appearance.

Furthermore, the cavity 2 is drilled, and the partition pin 3 is formed by naturally collecting the waste material generated during drilling, so that the template 1 structure suitable for the present invention can be obtained without special processing.

The above detailed description is specific to possible embodiments of the present invention, but the embodiments are not intended to limit the scope of the present invention, and equivalent implementations or modifications without departing from the technical spirit of the present invention are intended to be included in the scope of the present invention.

It will be apparent to those skilled in the art that various changes and modifications may be made in the embodiments of the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
