A multicast traffic transmission method includes: detecting (S) whether a transmission link between a designed forwarder (DF) and a traffic reception device is abnormal; and when the transmission link between the DF and the traffic reception device is abnormal, sending (S) a first request to a backup designed forwarder (BDF). A packet of the first request includes a protection mark and address information about the traffic reception device, and the first request is used for requesting the BDF to forward traffic to the traffic reception device.

A NOx sensor protection system includes a flow control device forming an internal chamber with exhaust and shield gas ports and a NOx sensor. The flow control device is configured to selectively allow a flow of exhaust from an exhaust pipe to the NOx sensor when an internal combustion engine is operated with a first fuel, and to selectively direct shield gas from the shield gas port at an angle of 135&#xb0; to 180&#xb0; to the NOx sensor to inhibit the flow of exhaust from the exhaust pipe to the NOx sensor when the engine is operated with a second fuel.

An integrated molding device suitable for the bending and hemming of a flat sheet, comprising a stand, a worktable, a slider, and a turning beam. The stand comprises a frame structure composed of an upper cross beam, a lower cross beam, and columns on both sides, two ends of the slider are connected to the columns on both sides by means of a pair of sliding pairs A respectively, and the clutching of a bending die is achieved by means of the linear movement of the sliding pairs A; the worktable is fixed on the lower cross beam, and the clutching of a pressing die is achieved by means of the linear movement of the sliding pairs A; two ends of a swing frame are connected to the columns on both sides by means of one connecting block respectively, the connecting block and the columns are connected therebetween by means of a pair of rotating pairs B, and the connecting block and the swing frame are connected therebetween by means of a pair of sliding pairs C. The present device may achieve the bending or pressing of a flat sheet according to differences in the amount of up and down movements of the slider; and on the basis of the pressing of the flat sheet, the hemming of the flat sheet may be achieved in cooperation with the swinging of a swing beam.

Provided is an auxiliary bending robot capable of processing two workpieces simultaneously, including a linear base slide rail, a slider, a movable major arm, a movable minor arm, a front arm, a swing link, and an additional seventh axis. The slider is slidably connected to the linear base slide rail, and a first axis is formed between the slider and the linear base slide rail. A top portion of the slider is directly or indirectly hinged to a rear end of the movable major arm through a second axis, a front end of the movable major arm is hinged to a rear end of the movable minor arm through a third axis, a front end of the movable minor arm is hinged to a rear end of the front arm through a fourth axis, and a front end of the front arm is rotatably connected to a middle portion of the swing link through a fifth axis. There are two additional seventh axes, the two additional seventh axes are symmetrically disposed on the swing link on two sides of the fifth axis, and each of the additional seventh axes is rotatably connected to the swing link. The present invention can bend two sheet metal plate parts at the same time, so that the efficiency is multiplied and the efficiency problem of automatic bending processing is practically resolved.
