Although the outer umbrella processing of the CNC large porcelain sleeve blanking machine adopts numerical control processing, the inner hole still adopts the profiling method. The inner hole profiling is that the roller of the crank end of the parallel four-bar linkage is pressed against the template having the same shape as the inner hole, and when the crank moves in the vertical direction, the cutter advances in the vertical direction according to the shape of the template. The tool is also fed in the horizontal direction to machine the inner hole into the shape of the template.
Although the outer umbrella is the first in China, the method of contouring the inner hole is still backward. The following problems exist: each type of product must have its corresponding inner hole template, and the number of templates is large. For large porcelain sleeve products (4000mm high), the height of the template is large (more than 4000mm) and it is difficult to process.
It takes a long time to replace the template. Since each time the template is changed, measurement and adjustment are performed, which takes a long time. The size of the inner hole of the porcelain sleeve is determined by the horizontal distance from the template to the center of the blanking machine. The position of the inflection point in the vertical direction of the inner hole is determined by the upper and lower positions of the template installation, and must be consistent with the inflection point position of the outer umbrella.
The template adjustment is difficult and the number of blanks used to adjust the template is large. The shape of the inner hole is determined by the perpendicularity of the template, except for the shape of the template. In addition, the height error of each blank is large (about several hundred millimeters), so the adjustment of the template is very difficult, and it needs to be repeated several times to meet the requirements. Every time you adjust the template, you need to process a product to check. Each template needs to be adjusted 2 to 3 times to adjust. Therefore, the blank is wasted seriously. The value of a large porcelain sleeve is about 10,000 yuan.

Tube cutting machines are used for cutting long metal stock or scrap, generally where accuracy is not an important consideration, and the size or shape of the material makes other cutting or shearing options (such as a cutting torch) impractical. Alligator shears are often used in conjunction with large metal shredders in the metal recycling industry, to [clean" or prepare scrap for shredding by removing unwanted fittings and other parts the Shredder will not accept.
