Nylon melon petal combined nesting sleeve for small aluminum strip splitting machine

Abstract

The invention discloses a nylon melon petal combined nest for a small aluminum strip splitting machine, which comprises three fan-shaped cylinders, the outer diameter of each fan-shaped cylinder is 300mm, the inner diameter of each fan-shaped cylinder is 150mm, and the fan-shaped cylinders have maximum stability; the fan-shaped column body is made of a high-wear-resistance polyamide nylon material, so that the fan-shaped column body is high in wear resistance, high in heat conductivity and long in service life; annular clamping grooves are formed in the upper edge portion, the middle and the lower edge portion of the outer ring of each fan-shaped column body, the width * depth of each annular clamping groove is 13 * 13 mm, the distance between each annular clamping groove and the upper edge portion and the distance between each annular clamping groove and the lower edge portion are 2 cm, the three fan-shaped column bodies are fixed by winding high-stretchability spring rings in the annular clamping grooves, and it is guaranteed that the radial size is flexibly adjusted when the fan-shaped column bodies are combined, nested and used, and the fan-shaped column bodies are full of tensioning force. A plurality of groove patterns in the transverse direction and the longitudinal direction are arranged on the surface of the outer ring of the fan-shaped cylinder body at equal intervals, and the width * depth of each groove is 3 * 3 mm, so that meshing friction force is formed between the nesting sleeve and the inner lines of the aluminum sleeve, and it is guaranteed that the aluminum sleeve is not prone to moving in the using process.

Description

technical field [0001] The invention relates to a combination and nesting of nylon melon petals for a small-sized aluminum strip slitting machine. Background technique [0002] With the development of automobile lightweight, the application of lightweight aluminum alloy strip materials is becoming more and more extensive. Some refined thick and narrow aluminum strip slitting poses a huge challenge to the equipment. The strip slitting machine mostly adopts the cone head feeding method, and the diameter of the cone head is relatively fixed, the most common is 150mm outer diameter, which requires that the parent roll before slitting must use a 150mm inner core sleeve to meet the requirements of the machine. On the other hand, if a thicker aluminum strip (such as 0.7mm or more) is used in the production process of the parent roll, if a 150mm inner core sleeve is used, it will be difficult to roll up and wrap the bottom, easy to unwind and staggered layers, and time-consuming An...
