Description

[0001] Pipe Production Shaft with Continuous Fiber Winding Method

[0002] Technical Field

[0003] The invention relates to a shaft used in GRP (glass fiber reinforced plastic) pipe production machines with the continuous fiber winding method.

[0004] The invention particularly relates to a shaft that enables the production of DN200 GRP (glass fiber reinforced plastic) pipes in pipe production machines by the continuous fiber winding method.

[0005] State of Art

[0006] Today, bearing-mounted aluminum beams with bearings are placed on the shaft used in GRP (glass fiber reinforced plastic) pipe production machines and covered with steel tape, ensuring continuous GRP pipe production.

[0007] In the systems used in the present art, the total thickness of the shaft, the aluminum beam with bearings and the steel belt constitutes the inner diameter of the GRP pipe. The inner diameter of a GRP pipe with a DN 200 diameter is 208 mm. The inner diameter of a GRP pipe with a DN 250 diameter is 260 mm. In the present art, the minimum internal diameter of a DN250 pipe can be reduced to 260 mm. For this reason, it is not possible to produce GRP pipes for the internal diameter setting of 208 mm, which is DN200 in the current system.

[0008] The document numbered TR2020 / 03848 can be cited as an example of the state of the art in the literature research. The said document relates to the production of glass fiber-reinforced composite pipes. In the said production, the glass fiber bobbins that will form a layer along the pipe axis during the production of the composite pipe are placed on transport racks and the ends of the placed fiber coils are passed through the guides and polyester / vinyl ester filling resin vessels and the heat-controlled mold and combined with each other in order to be distributed regularly around the axis of the pipe profile to be processed. However, the pipe diameters produced in the said production method are not specified.As a result, the existence of the above problems and the inadequacy of existing solutions have necessitated development in the relevant technical field.

[0009] Purpose of the Invention

[0010] c

[0011] The main purpose of the invention is to provide a shaft that enables the production of DN200 GRP (glass fiber reinforced plastic) pipes in pipe production machines by the continuous fiber winding method.

[0012] The purpose of the invention is to eliminate the use of aluminum beams with bearings and to provide a shaft that enables the production of DN200 GRP pipes with an internal diameter of minimum 208 mm with a 206 mm shaft and a total of 2 mm steel belt with steel belt flow bearings mounted directly embedded into the shaft.

[0013] Another purpose of the invention is to provide a shaft in which the steel belt enters the inner tube by turning at least two turns in the return unit, unlike the current system, in order to complete the return flow of the steel belt, and in which the return maneuver can be performed without damaging the steel belt, thanks to the return tower being longer than the current system, unlike the current system.

[0022] - a return tower, which is located at the end of the main shaft with bearing channels and transfers the steel belt to the inner tube for the return of the steel belt and also provides the necessary maneuver to prevent physical deformation of the steel belt,

[0023] - steel belt slider bearing group limit flange, which connects the return unit bearing configuration and inner tube to prevent the steel band from dispersing by connecting it together for its return

[0042] Detailed Description of the Invention

[0043] In this detailed description, the preferred alternatives of the saft, which is the subject of the invention, are described only for the purpose of better understanding the subject and without forming any limiting effect.

[0044] A general view of the shaft, which is the subject of the invention, is given in Figure 1. Accordingly, the shaft in its most basic form, comprises a shaft with bearing channels (10) containing embedded steel belt flow bearings (30) during the movement of the steel belt in the GRP (glass fiber reinforced plastic) pipe production machine with the continuous fiber winding method, an inner tube (20) is passed through the main shaft with bearing channels (10) and fixed to the return unit of the GRP pipe production machine by the continuous fiber winding method and has a steel belt passing through it, a steel belt flow bearing (30), which is embedded in the main shaft with bearing channels (10) and provides the steel belt flow, the adjustable pusher cam flange (40) that connects the main shaft with bearing channel (10) to the GRP pipe production machine and enables mirror adjustment, a steel belt movement stud (50) that pushes the steel belt on the main shaft with bearing channel (10), an embedded bronze pusher bearing (60) connecting the steel belt movement stud (50) to the main shaft withbearing channel (10), a steel pusher body (70) containing the embedded bronze pusher bearing (60) and the steel belt movement stud (50), a pusher cam bearing (80), which is located on the steel pusher body (70) and provides the forward movement of the steel belt due to its shape, a return unit (90) that is connected to the main shaft with bearing channels (10) and ensures that the movement of the steel belt remains in an infinite loop, a return unit bearing configuration (100) which is connected to the main shaft with bearing channel (10) and increases the maneuverability of the main shaft with bearing channel (10) to realize the return movement of the steel belt, a return tower (110) that is located at the end of the main shaft with bearing channels (10) and transfers the steel belt to the inner tube (20) for the return of the steel belt and also provides the necessary maneuver to prevent physical deformation of the steel belt, a steel belt slider bearing group limit flange (120) which connects the return unit bearing configuration (100) and inner tube (20) for the return of the steel belt and prevent it from falling apart by connecting

[0045] After the adjustable pusher cam flange (40) is fixed to the mirror hub in the GRP (glass fiber reinforced plastic) pipe production machine by the continuous fiber winding method, the assembly of the shaft, which is the subject of the invention, is carried out. The inner tube (20) is fixed to the return unit of the GRP pipe production machine. The first mirror adjustment is performed with the adjustable pusher cam flange (40).

[0046] By starting the steel belt winding in the GRP (glass fiber reinforced plastic) pipe production machine with the continuous fiber winding method, the steel belt is given a forward motion by the embedded bronze pusher bearing (60).

[0047] Mirror adjustment is made again using the adjustable pusher cam flange (40) according to the advancement of the steel belt. The steel belt winding begins again. The advancement movement is provided by steel belt flow bearings (30) via embedded bronze pusher bearing (60). The steel belt, which runs along the main shaft with bearing channels (10), initiates the return movement with the return unit bearing configuration (100). The return tower (110) provides the necessary maneuver to prevent physical deformation of the steel belt and returns it to the machine used in pipe production by means of the inner tube (20) and continuous fiber winding method.
