Claims (4)

1. Устройство для формования труб, имеющее формовочный туннель, который содержит верхний по ходу движения формовочный блок и по меньшей мере один нижний по ходу движения формовочный блок, причем каждый формовочный блок включает в себя секции формовочного блока, которые смыкаются для формования трубы и размыкаются для освобождения трубы, формовочные блоки совместно движутся к нижнему по ходу движения концу устройства при формовании трубы, которая, перемещаясь через формовочный туннель, охлаждается и дает усадку по диаметру и длине, а при освобождении трубы формовочные блоки движутся по отдельности к верхнему по ходу движения концу устройства, и каждый формовочный блок имеет полую зону для формования трубы, причем для компенсации усадки трубы указанная зона нижнего по ходу движения блока является уменьшенной по диаметру и длине относительно зоны верхнего по ходу движения блока.1. A device for forming pipes, having a molding tunnel, which contains the upper in the direction of movement of the molding block and at least one lower in the direction of movement of the molding block, and each molding block includes sections of the molding block, which are closed to form the pipe and open for to release the pipe, the molding blocks move together towards the lower end of the device during molding of the pipe, which, moving through the molding tunnel, cools and shrinks in diameter and length, and when to free the pipe, the molding blocks move separately to the upper end of the device, and each molding block has a hollow zone for molding the pipe, and to compensate for shrinkage of the pipe, this zone of the lower block in the direction of movement is reduced in diameter and length relative to the zone of the upper block in the direction of travel block. 2. Устройство по п.1, содержащее промежуточный формовочный блок между верхним по ходу движения и нижним по ходу движения формовочными блоками.2. The device according to claim 1, containing an intermediate molding block between the upper in the direction of travel and the lower in the direction of movement of the molding blocks. 3. Устройство по п.2, в котором промежуточный формовочный блок имеет полую зону для формования трубы, уменьшенную по диаметру и длине относительно полой зоны для формования трубы в верхнем по ходу движения формовочном блоке и увеличенную по диаметру относительно полой зоны для формования трубы в нижнем по ходу движения формовочном блоке.3. The device according to claim 2, in which the intermediate molding unit has a hollow zone for forming the pipe, reduced in diameter and length relative to the hollow zone for forming the pipe in the upper direction of the molding block and increased in diameter relative to the hollow zone for forming the pipe in the lower in the direction of movement of the molding block. 4. Устройство по п.2, в котором промежуточный формовочный блок имеет полую зону для формования трубы, уменьшенную по диаметру и длине относительно полой зоны для формования трубы в верхнем по ходу движения формовочном блоке и согласующуюся по диаметру и длине с полой зоной для формования трубы в нижнем по ходу движения формовочном блоке.4. The device according to claim 2, in which the intermediate molding unit has a hollow zone for molding the pipe, reduced in diameter and length relative to the hollow zone for molding the pipe in the upper along the movement of the molding block and consistent in diameter and length with the hollow zone for forming the pipe in the downstream molding block.
