1. the process is different from the existing integral forming processing process of the socket glass pipeline, the main body and the plug section of the socket glass pipeline are manufactured separately, and finally the main body and the plug section are connected together. The production of the main body of the socket glass pipeline only needs two processes of mould forming and demoulding, so that the repeated transportation in the groove grinding process and the manufacturing process is reduced, particularly, the production time is greatly reduced for the production of the socket glass pipeline with large pipe diameter, and the production efficiency is improved. The production of the plug section needs four procedures of mould forming, groove grinding, demoulding and cutting. Although the production process is increased, a plurality of plug segments can be produced at one time, the production time is saved through phase change, and the production efficiency is improved.
The process can manufacture the socket glass fiber reinforced plastic pipeline in batches at one time, greatly improves the production efficiency and reduces the production cost. Meanwhile, the main body and the plug section of the socket glass fiber reinforced plastic pipeline are separately produced, the socket glass fiber reinforced plastic pipeline is further refined, and the manufacturing difficulty is reduced. In addition, because the plug section is polished and cut through the whole thickened glass steel tube, the whole socket glass steel tube cannot be scrapped even if the offset occurs in the groove grinding process, and the waste of materials and working hours is avoided.
2. And the semi-finished socket glass fiber reinforced plastic pipeline obtained in the step S1 is provided with a socket head section. As the head-bearing segment does not need to be additionally processed, the head-bearing segment and the main body of the socket glass fiber reinforced plastic pipeline can be molded together, the head-bearing segment does not need to be produced independently, and the production time is saved.

It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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.
Embodiments of the present invention will now be described with reference to the accompanying drawings.
Example 1
The specific implementation mode of the invention is shown in fig. 1, and the production process of the socket glass fiber reinforced plastic pipeline comprises the following steps:
s1, manufacturing a plurality of semi-finished product socket glass fiber reinforced plastic pipelines without plug sections for later use;
s2, manufacturing a thickened glass steel tube, grinding a plurality of uniformly arranged clamping grooves around the outer wall of the thickened glass steel tube after solidification, and demolding for later use;
s3, uniformly cutting the thickened glass fiber reinforced plastic pipe obtained in the S2 to obtain a plurality of glass fiber reinforced plastic pipe sections with clamping grooves;
and S4, connecting the glass fiber reinforced plastic pipe section obtained in the S3 with the semi-finished socket glass fiber reinforced plastic pipe obtained in the S1 to obtain a finished socket glass fiber reinforced plastic pipe.
The process is different from the existing integral forming processing process of the socket glass fiber reinforced plastic pipeline, the main body and the plug section of the socket glass fiber reinforced plastic pipeline are divided into two parts to be manufactured separately, and finally the two parts are connected together to obtain a complete socket glass fiber reinforced plastic pipeline. The production of the main body of the socket glass pipeline only needs two processes of mould forming and demoulding, so that the repeated transportation in the groove grinding process and the manufacturing process is reduced, particularly, the production time is greatly reduced for the production of the socket glass pipeline with large pipe diameter, and the production efficiency is improved. The production of the plug section needs four procedures of mould forming, groove grinding, demoulding and cutting. Although the production process is increased, because a plurality of plug segments can be produced at one time, the production time is saved and the production efficiency is improved.
Taking a socket glass fiber reinforced plastic pipeline with the specification of DN500 as an example, the length of a pipeline mould is 12000mm, the length of a plug segment is 200mm, and the weight of the mould and a product is heavy. The socket glass fiber reinforced plastic pipeline is processed and produced by adopting the prior process, the mould and the formed semi-finished socket glass fiber reinforced plastic pipeline are transported to a groove grinding machine together, then 1 set of plug section is ground, and the time from the transportation to the completion of the groove grinding is about 2 hours, namely the grinding time of 2 hours is needed for 1 set of plug section. And the length of the plug segment is 200mm, compared with the length of the whole product, the plug segment occupies a small ratio, and is easy to deviate during the groove grinding operation, so that the waste of materials and working hours is caused.
The socket glass fiber reinforced plastic pipeline is produced by adopting a new process, the length of a pipeline mould is 12000mm, a plug section with the specification of 200mm is independently manufactured, namely, 60 plug sections can be ground out from one pipeline. The mould and the formed glass steel tube are conveyed to a groove grinding machine together, then 60 sets of plug sections are ground, and about 6 hours are needed from the conveying to the groove grinding, namely 0.1 hour is needed for 1 set of plug sections. Compared with the prior art, the groove grinding time of a single clamping groove is greatly reduced, and the production efficiency is improved due to the diversion.
The process can manufacture the socket glass fiber reinforced plastic pipeline in batches at one time, greatly improves the production efficiency and reduces the production cost. Meanwhile, the main body and the plug section of the socket glass fiber reinforced plastic pipeline are separately produced, the socket glass fiber reinforced plastic pipeline is further refined, and the manufacturing difficulty is reduced. In addition, because the plug section is polished and cut through the whole thickened glass steel tube, the whole socket glass steel tube cannot be scrapped even if the offset occurs in the groove grinding process, and the waste of materials and working hours is avoided.
