Background
The cable forming die comprises a compacting forming die, a cabling die, an extrusion die and the like, and is characterized by belonging to a plastic die, wherein the final hot pressing device in the whole plastic extrusion process directly determines the quality and success and failure of cable processing, and the die design and the use reliability are highly valued. Particularly when extruding insulation and jacket layers of wires and cables with plastic extruders, extrusion dies are one of the most critical factors in controlling the quality of the plastic extrusion coating.
In the production process of the die, die measurement is a process before delivery. For some regular or standard dies, a scale may be used for measurement, but for some complex dies, it is difficult to perform overall, omnibearing measurement, and the accuracy of the die cannot be accurately measured.
An advanced measuring instrument exists: the two-dimensional image measuring instrument (also called image type surveying instrument) is based on CCD digital image and is produced by means of computer screen measuring technology and powerful software capability of space geometric operation. The displacement value of the optical ruler can be read quickly, and the displacement value has basic functions of space geometric operation, graphic display, dimension marking, CAD graphic output and the like. When the device is used, the die is placed on the tray of the secondary image measuring instrument, and the die at the lower end is reflected by the camera at the upper end, so that the data about the outer diameter size of the inner die, the outer diameter size of the outer die, the matching degree of the inner film and the outer film and the concentricity of the inner film and the outer film of the die (comprising the inner die and the outer die) can be rapidly acquired on the secondary image measuring instrument. However, in the measurement, it takes much time to adjust the level and stability of the mold (the requirement for professional ability of the measurer is high), otherwise, the measured data deviation is large after the mold is put to incline, and in addition, since the outer mold size of the upper end of the mold is larger than the inner mold of the lower end, the taper of the inner mold cannot be measured, so that after the first measurement of the mold, the mold needs to be put again (which is difficult because the upper end of the inner mold is a fine spike) in order to measure the taper of the inner mold.
