Cables are an indispensable infrastructure in modern society for transporting electric power, data and communication signals. Its performance, reliability and safety are critical, and these aspects are directly affected by the quality and performance of the insulating material. Accordingly, there is a need in the cable industry for an efficient method to evaluate the performance of insulation materials to ensure that they meet the requirements of various applications.

Cable jackets are an important component of the cable whose properties directly affect the insulation, electrical properties and durability of the cable. To evaluate the performance of an insulation material, cable manufacture typically performs a tensile test that requires the preparation of dumbbell test pieces of a particular shape, which can measure key performance indicators such as tensile strength, elastic modulus, and strain at break of the insulation material. Thus, the preparation of high quality dumbbell test pieces is a critical step in the cable manufacturing industry.

Traditionally, preparation of dumbbell test pieces is a cumbersome process requiring a large number of manual operations. These operations include measuring, cutting and blanking the insulating material, which is not only time-consuming and laborious, but also prone to introducing human error, thereby affecting the accuracy of the test results. Therefore, a need for a more efficient, accurate, and automated method of preparing dumbbell test sheets is a pressing need in the cable industry.

The invention has the advantage of being capable of manufacturing the dumbbell-shaped outer sheath of the cable, solves the problem that the inner and outer surfaces of the dumbbell-shaped outer sheath of the cable are manually cut off to form the middle layer of the outer sheath, which is time-consuming and labor-consuming, but the existing equipment has the following problems:
