Problems solved by technology

In order to make a standard, a test is often done after stretching. It is inconvenient to measure with a ruler because one side is high and the other side is low. There are various models, and the upper and lower stages of the same machine are different from the front, middle and rear. There are dozens to hundreds of types. It is not a small fortune for manufacturers specializing in the production of spiral blades to prepare a variety of pipes. expenses, and some are difficult to buy for a while

Abstract

The invention discloses a combination molded tube capable of nesting spiral blades and aims to provide a combination molded tube which is low in weight and cost, adjustable in size, multifunctional and capable of nesting spiral blades. The technical scheme of the combination molded tube is characterized in that at least two round plates with multiple slightly unedged holes drilled in peripheral planes are flatly arranged on an upper part and a lower part of a stand column in the center through screws respectively, multiple small round bars are vertically inserted into the unedged holes in peripheries of the upper round plate and the lower round plate respectively to form a cylindrical sleeve, the central stand column is vertically installed on a lower base, and a plane of the base is larger than planes of the two round plates so as to prevent the combination molded tube from toppling. The combination molded tube capable of nesting the spiral blades can be multipurpose as long as the round plates of corresponding sizes are replaced according to a process requirement.

Description

[0001] technical field [0002] The present invention relates to a kind of tool used for testing for the production machinery equipment of brick and tile factory, more specifically is used for testing a spare part in the screw extruder, that is, the screw blade is a standard sleeve mold tube. Background technique [0003] Most of the spiral blades are drawn from steel plates. Due to the certain elasticity of steel plates, they will automatically shrink a small amount of size when the tension is removed after being stretched in place. The rebound rate varies according to the material and size of the steel plates. The more rebound , the inner diameter is correspondingly larger, and there is inevitably a certain error when cutting the material. Therefore, it is difficult to achieve the standard size of the inner and outer diameters, and if there is a large difference, it will become a waste product. In order to make a standard, a test is often done after stretching. It is incon...
