Background
In the production process of the extruded pipe, the outer diameter of the pipe is determined by the sizing sleeve size, the material formula shrinkage rate, the ambient temperature, the water temperature of a water tank, the vacuum negative pressure and other factors. The influence of adjusting water temperature and vacuum negative pressure on the outer diameter of the pipe is very limited, when the required outer diameter of the pipe is too far away from each other and cannot pass through the water temperature and the vacuum conditioning time, the machine must be stopped and then the sizing sleeve is replaced, the process of replacing the sizing sleeve is time-consuming and labor-consuming, waste products are more, and a large amount of materials and energy are wasted. In order to meet the requirements of different shrinkage rates, production environment temperature difference, cooling water temperature difference and different standard outer diameter/inner diameter/wall thickness differences of various material formulas, a plurality of sizing sleeves with similar sizes are required to be equipped for the same product/products with similar sizes to meet the production requirements. For example, the sizing sleeve is also used for producing a pipe with an outer diameter of 110, and usually a plurality of sizing sleeves with similar sizes, such as inner diameters of 110.2/110.4/110.6/110.8/111/111.2, are required to be prepared, and then the sizing sleeve with a proper size is selected for production according to various production conditions and standard requirements.
At present, the diameter of the pipe can be produced by using the same sizing sleeve by producing through the sizing sleeve with variable diameter, and the sizing sleeve does not need to be replaced. For example, patent document ' CN200420082004.0 ' discloses a but variable diameter sizing cover of production plastic tubing, and this sizing cover is through manual mode regulation carousel, and the rethread is many pull rods pulling clamp plate, reaches the mode of main part and clamp plate relative movement and debugs, at the process of a plurality of pull rods pulling clamp plate, the volume of every pull rod position of strict control needs, after meetting the circumstances such as part machining precision is not high, part fit clearance, material wearing and tearing such as gear, pull rod, can't guarantee the uniformity of the displacement of pull rod. And the pressure plate moves obliquely, the stress matched with the main body is uneven, the integrity of the sizing sleeve main body, particularly the cut sizing sleeve main body is endowed with the characteristic of elastic deformation of the sizing sleeve, and meanwhile, the strength of the sizing sleeve is greatly weakened, and the sizing sleeve is easy to deform into an oval shape and even break and damage. Therefore, the existing variable-diameter sizing sleeve is prone to damage, difficult to repair, short in service life, poor in quality of produced pipes, difficult to guarantee out-of-roundness and the like.

The motor 402 drives the fixing portion 102 to rotate together through belt transmission, and when the fixing portion 102 rotates, the motor moves forward or backward relative to the fixing plate 2 due to the threaded connection with the fixing plate 2. Because sizing cover body 1 moves in the water tank, and fixed plate 2 installs in the tank wall of water tank, and threaded connection can have better leakproofness. Meanwhile, the sizing sleeve body 1 can rotate to advance or retreat, so that better power can be achieved in water, and resistance in water can be reduced.
