Title: High-strength steel tube bending die mandrel
Inventor: LIN JIANWEI
IPC: B21D9/04
Filed: 2020-12-22
Abstract: A high-strength steel tube bending die mandrel. The die mandrel is a straight rod-type mandrel and comprises a mandrel pull rod (4) and a mandrel body (1). The mandrel pull rod (4) is screwed to the rear end of the mandrel body (1). The shape of the cross section of the mandrel body (1) is adapted to the shape of a steel tube (5). The size of the cross section of the mandrel body (1) is less than the inner diameter of the steel tube (5). When the mandrel body (1) is in the steel tube (5), a unilateral gap between the mandrel body (1) and the steel tube wall is d, wherein 0<d≤0.5mm. The high-strength steel tube bending die mandrel is an integrated rod-type mandrel, thus solving the problem of conventional joint mandrels that during the bending of a high-strength material, the material is prone to be recessed and stuck at a joint. The design size of the straight rod-type mandrel is specifically designed, and the positions at which the front end of the mandrel body (1) contacting inner walls of outer R corners of the steel tube are designed to be round R corners, thus avoiding sharp points of right-angle corners from causing deformation at the outer R corners of the steel tube (5). When the high-strength steel tube (5) is bent, the problem of recessing can be reduced, and thus the product cost is lowered.

Abstract: The present application relates to the technical field of communications, and provides a routing configuration method and device. The method comprises: after a first terminal moves out of the service range of a UPF currently providing a service, a first SMF inserts a first I-UPF in a user plane path of the first terminal, and configures a first routing rule corresponding to a second terminal for the first I-UPF, the first routing rule being used for sending, to a second A-UPF, a packet having destination address information being address information of the second terminal. The second A-UPF is different from a first A-UPF, the second A-UPF provides an anchor service for the second terminal, and the first A-UPF provides an anchor service for the first terminal. Thus, a packet having the destination address information being the address information of the second terminal can be directly forwarded to the first A-UPF from the first I-UPF, without the need to forward same to the second A-UPF by the first I-UPF through the first A-UPF, thereby reducing the packet forwarding time delay.
