Description

The utility model relates to equipment for the manufacture of pipes from composite materials.

A known installation for the manufacture of pipes from laminated plastics containing device winding, polymerization and removal from the mandrels of finished products - and.with. 234652 B 29 D 23/12.

In such an installation, winding, polymerization and removal devices from the finished product mandrels are made in a single housing with heaters located inside the holders and hollow mandrels mounted on the holders.

The disadvantage of this installation is its limited technological capabilities, due to the short length of the manufactured pipes due to the cantilever arrangement of the holders with mandrels and the inability to obtain combined (for example, polyethylene-fiberglass) pipes.

Known installation (line) for the manufacture of pipes from composite materials, containing a winding machine, a polymerization chamber, a puller, drives mandrels and finished products, transport device mandrels and reloading devices - and.with. 362699 B 29 D 23/12.

According to its characteristics and the achieved result, this line is closest to the claimed one and adopted as a prototype.

In this line, the puller divides the polymerization chamber into two parts: the beginning (with heating lamps) and the end (without heating lamps, on waste heat) of polymerization.

The line is made with two-support installation of mandrels and mandrels with the product in all operations of the technological cycle, which allowed, to manufacture

pipes of significantly greater length and diameter and somewhat expanded the technological capabilities of the line.

However, the achieved positive result is insufficient, since it is impossible to produce combined pipes on this line. And due to the fact that the end of the polymerization is performed after removing the pipe from the mandrel, the accuracy and bearing capacity of the manufactured pipes are impaired, which further reduces the technological capabilities of the line.

The objective of the utility model is to expand the technological capabilities of the line.

This problem is solved by improving the line for the manufacture of pipes from composite materials, containing a winding machine, a polymerization chamber, a puller, drives mandrels and finished products, the transport device mandrels and handling devices.

The improvement consists in the fact that the line is equipped with a polyethylene pipe storage device, combined with a finished product storage device, a device for installing a polyethylene pipe on a mandrel, combined with a puller, an adhesive layer winding machine and interoperational mandrel drives installed in front of the last and transport mandrel device made in the form of a trolley on rails located along the winding machine.

Providing the line with a polyethylene pipe storage device, combined with a finished product storage device, a device for installing a polyethylene pipe on a frame, combined with a puller, an adhesive layer winding machine and an interoperable mandrel storage device in front of it, allows you to install a polyethylene pipe on the mandrel and apply an adhesive layer to it.

The supply of the line with an interoperational storage of mandrels in front of the transport device of mandrels, made in the form of a trolley on rails located along the winding machine, allows the mandrel with a polyethylene pipe and an adhesive layer to be installed immediately or after

transfer the interoperational drive to the trolley and along the rails to the loading position of the winding machine and, performing the remaining operations of the line, get a combined bi-plastic pipe, thereby expanding the technological capabilities of the line.

Below, with reference to the attached drawing, which shows:

Figure 1 - Line (top view) at the time of removal of the finished product from the mandrel;

Figure 2 - Line (top view) at the time of installation of the polyethylene pipe on the mandrel, describes the proposed line for the manufacture of composite materials. The thin lines in FIG. mandrels, finished products and polyethylene pipes are shown.

The line contains a winding machine 1, a polymerization chamber 2, a puller 3, a drive 4 of mandrels 5, a drive 6 of finished products 7, a transport device 8 of mandrels 5 and reloading devices 9, 10 and 11 in the form of manipulators on suspended (ceiling guides A, B and C (shown in dash by dotted lines).

The line is equipped with a drive 12 of polyethylene pipes 13, combined with a drive 6 of finished products 7 and made in the form of a trolley 14 on rails 15, a device 16 for installing a polyethylene pipe 13 on a mandrel 5, combined with a puller 3 (having a trolley 17 with sockets D and E under polyethylene pipes 13 and a mandrel 5 with finished products 7 mounted on rails 18), a machine 19 for winding the adhesive layer and a drive 20 of mandrels 5 with a polyethylene pipe 13 and an adhesive layer 21 on it in front of the transport device 8, made in the form of a cart on a rail ah 22 located along the winding machine 1.

The line works as follows.

The transport device (trolley) 8 with a mandrel located on it (with or without a polyethylene pipe) 5 is moved to the loading position of machine 1 (shown by thin dashed lines). Mandrel 5

set reloading device (manipulator) 10 in the machine 1 and perform the winding of fibrous material with a binder, after which the same device is loaded into the polymerization chamber 2.

After polymerization, the mandrel 5 with the product 7 reloading device 11 is installed in the slot E of the trolley 17 of the puller 3 and its winch 23 pull the mandrel 5 from the product 7 (position in figure 1), which device 11 is loaded onto the drive 6. The polyethylene pipe 11 is the same device 13 from the drive 12 is installed in the slot D of the trolley 17 and by moving the latter along the rails 18, a polyethylene pipe 13 is aligned with the mandrel 5, after which the mandrel 5 is pulled into the polyethylene pipe 13 by the device 16 (position in FIG. 2) and the resulting assembly (polyethylene I am the mandrel pipe) with the winch 23 of the puller 3 is moved to the operating area of the reloading device 9, with which it is installed in the machine 19, where the adhesive layer is wound on the polyethylene pipe 13 (for example, sevilen film) 21, then overloaded by the device 9 onto the transport device 8 and moved them into the loading zone of the winding machine 1. Next, the manufacturing cycle of the biplastic pipes is repeated.

In the manufacture of fiberglass pipes, the mandrel 5, after removing the finished product 7 from the puller 3, is immediately transferred by the reloading device 9 to the transport device 8, which is fed into the loading zone of the winding machine 1 and then in a cycle.

In both versions of the manufacture of pipes (biplastic and fiberglass) mandrel 5 can, if necessary, accumulate on interoperational drives 4 and 20.

The line for manufacturing pipes from composite materials (due to the possibility of manufacturing biplastic pipes with an inner layer in the form of a polyethylene pipe) is characterized by advanced technological capabilities in comparison with the prototype.
