Description

The invention relates to a variety of technological processes, namely, plastics processing, and is used to remove internal weld seams of polyethylene pipes that are welded. By welding polyethylene pipes, a roller joint is formed on the outer and inner walls of the pipe. The inner welding seam must be removed as it will prevent fluid flow inside the pipe.

Known technical solution - US patent no. US 4,085,505, which discloses a device for removing an internal weld of a polyethylene tube comprising a motion transfer rod with a handle with a knife attached at its end.

Removing the inner weld seam of the tubes with this unit does not guarantee the quality of the tube at the seam removal and requires a great deal of force to rotate the motion transfer rod.

The closest analogue to the proposed solution is the WIDOS-INNENWULSTENTFER 300 (Art.No. 561 00), a polyethylene pipe inner welding machine used by Wilhelm Dommer Sohne GmbH, which consists of a surface-sensing welding cutter with a knife connected to a voltage of 230 V. , guide rails, distance details, motion transmission rod (Appendix 1).

The disadvantage of this device is that the weld can only be removed immediately after welding, when the weld is hot, or requires additional heating when the weld has cooled.

The purpose of the proposed technical solution is to ensure high quality welding of the welds in polyethylene pipes at any time, regardless of the weld temperature.

The object is achieved by the fact that the device for removing the internal welding seam of the polyethylene pipes has a motor for transferring milling gear connected to a motor which is attached to the base of the housing having a first spring with a spring mounted in the center and a second and third supports facing one side. of which, mounted at the rear of the housing, a welding locking roller is mounted on the front of the housing, placed in front of the milling cutter, and the said transmission rod is connected to the housing by a universal joint. The unit also has a chip removal stopper connected to the housing by a motion transfer rod connected to the housing by a cardan joint, and a support locking center of the motion transfer bar to the center of the tube.

The drawing shows a general view of the device.

The device for removing the weld 1 in the polyethylene tube 2 consists of a mill 3 connected to the motor 4, a welding roller 5, a support 6 having a spring 7, a support 8 and 9, a parallel plug 10. The motor 4 a welding roll 5, a support 6, a support 8, the support 9 and the parallel plug 10 are secured to the housing 11 which is connected to the drive shaft 12 by the motion transmission bar 13. The motion transmission bar 13 is inserted into the recess 15 of the support 14. The support 14 has locking elements 16A and 16B and screws 17A and 17B. The motion transmission rod 13 has a T-shaped handle 18 at the end. The electric motor 4 is connected to the mains (220 V) by means of a wire 19. The ends 6, 8 and 9 of the supports end with rollers 20,21 and 22.

By removing the weld 1 in the polyethylene pipe 2, which can have a diameter of 150 to 500 mm. the motion transmission rod 13 is inserted into a notch 15 in the support 14, which can move in a longitudinal direction and make a rotational movement, and is connected to the housing 11 by a cardan connector 12. The cardan connector 12 maintains parallelism between the housing 11 and the walls of the polyethylene tube. The support 14 is secured to the edge of the tube 2 by means of the locking elements 16A and 16B and is fixedly fixed by means of the fixing screws 17A and 17B. With the aid of the movement transfer rod 13, the device is pushed into the tube 2 and pushed until it reaches the welding seam l. The motor 4 is then started and the welding roller locking roller 5 jumps the seam at its M-spot and starts milling the seam 1. Thanks to the spring 7, the supports 6, 8 and 9 press against the walls of the pipe 2. Manual rotation of the T-handle 18 rotates the motion transmission rod 13. With the help of rollers 20, 21 and 22, the machine rotates evenly in the tube 2. Using the minimum torque, turning the machine 1 times (seam circumferentially) mills the seam 1 into chips. When the work is completed, the electric motor 4 is disconnected from the mains. When pulling the unit out of tube 2, the end of the unit is parallel

r.

stopper 10 removes chipped seams.

The device for removing the welding seam in the polyethylene pipe is to be called BroFeX 150 - 500.
