The invention discloses a thermal-stamping formation method for rapidly and efficiently realizing performance gradient distribution of a high-strength steel part. The thermal-stamping formation methodcomprises the following steps: step (1) placing a plate material on the upper surface of a lower mold block of a thermal-stamping forming device; step (2) providing current for induction coils whichare separately arranged inside heating holes of an upper mold block and the lower mold block, and controlling the heating temperature of a front region and a rear region of each of the upper mold block and the lower mold block according to performance gradient distribution requirements of a thermally formed part; step (3) controlling the upper mold block to move upwards to a maximum position so that the upper mold block forms a convex die of a thermal stamping device, and controlling the lower mold block to move downwards to the maximum position so that the lower mold block forms a concave dieof the thermal stamping device; step (4) controlling the upper mold block to rapidly move downwards to realize stamping formation; and step (5) charging cooling water channels of the upper mold blockand the lower mold block with cooling water to finally obtain a high-strength steel thermally-formed part which satisfies the performance gradient distribution requirements.

The invention discloses an antistatic high-strength electrical shielding data cable comprising eight copper conductor units and an aramid reinforcing member. Each copper conductor unit comprises an aramid fiber which is arranged in the center, an internal conductive layer and an external conductor layer. Four symmetrical insulating wire pairs are twisted on the external surface of the aramid reinforcing member to form a cable core. A second teflon layer longitudinally wraps the external surface of the cable core. The gap between the second teflon layer and the four symmetrical insulating wirepairs is filled with multiple cotton yarns. One cotton fiber wire winds the external surface of the second teflon layer to form a buffer slide layer. The winding direction of the cotton fiber wire isopposite to the twisting direction of the four symmetrical insulating wire pairs. Multiple metal wires are wound on the external surface of the buffer slide layer in parallel to form a metal shieldinglayer. The metal wire external surface of the metal shielding layer is wrapped by a third teflon tape. The data cable is low in friction coefficient and flexible and tension-resistant without frictional static electricity and can still guarantee structural and electrical performance stability after frequent movement.
