The invention relates to a pintle chain bending plate forming device. The pintle chain bending plate forming device comprises an upper die structure and a lower die structure, wherein the upper die structure comprises an upper die plate, an upper base plate, an upper die base and an upper forming die, the upper die plate, the upper base plate and the upper die base abut against one another, the upper forming die is installed on the upper die base, the lower die structure comprises a positioning block, a lower forming die, a lower base plate, a bottom plate, a floating block, an ejector rod and an elastic block, a groove used for bending of a workpiece is formed in the center of the lower forming die, the positioning block is installed on the lower forming die, the floating block is arranged in the groove, the lower forming die and the bottom plate are installed in a matched mode through the lower base plate, ejector rod through holes are formed in the middle of the lower base plate and the middle of the bottom plate, the size of the groove is larger than that of the through hole in the middle of the lower base plate and that of the through hole in the middle of the bottom plate, the elastic block is fixed through an upper clamping plate and a lower clamping plate, one end of the ejector rod abuts against the floating block after penetrating through the through hole in the middle of the lower base plate and the through hole in the middle of the bottom plate, and the other end of the ejector rod is installed on the upper clamping plate and is in contact with the elastic block. According to the pintle chain bending plate forming device, the depth of parallelism of the two edges of a chain bending plate is increased, the precision of arcs bent by the chain bending plate is improved, the correction process and the chamfering process are omitted, and the quality of a chain is improved.

A forming method and forming mold for a semi-closed thin plate part, the forming mold includes a base and an inner tire, the base is provided with a concave cavity matching the shape of the bottom of the part, and the inner tire contains a left inner tire , the right inner tire and the support core, place the bent part on the cavity of the forming mold base, and then fill the left inner tire, right inner tire and support core in the bent part in turn Cavity, use positioning pins to fix and position the forming parts, and finally disassemble the forming mold, remove the process lugs, and correct the external dimensions of the parts.

An electronic device includes a magnetic sensor which detects a magnetic field around the electronic device and outputs magnetic data in accordance with the magnetic field detected by the magnetic sensor, a position acquiring section which acquires position information regarding a geographic position of the electronic device, and a processing unit. The processing unit acquires, from the position acquiring section, specific position information for a specific position of the electronic device when an output vector of the magnetic data is oriented to a magnetic pole direction of the earth, derives a geomagnetic vector at the specific position based on the specific position information, and acquires an offset value based on a comparison between the geomagnetic vector and the output vector.

Embodiments of the present invention provide a data transmission method, network element equipment, and a communication system. The method includes: receiving a creation or update message of a PDP context sent by a sending end, the creation or update message carrying a quality of service parameter of the PDP context; judging according to the quality of service parameter whether the user plane tunnel corresponding to the PDP context can pass The UDP-Lite protocol performs encapsulation, and returns a response message carrying the judgment result information to the sender, so that when the sender receives the judgment result information that can be encapsulated through the UDP-Lite protocol, the PDP context is updated through the UDP-Lite protocol. The corresponding bearer user plane tunnel is encapsulated. The technical solution provided by the embodiment of the present invention can encapsulate some services with high fault tolerance into UDP-Lite protocol messages, which reduces the verification of the message load and significantly improves the efficiency of data transmission compared with the prior art. efficiency.

The embodiment of the invention provides a data transmission method, network element equipment and a communication system. The method comprises the steps that a PDP context creating or updating message transmitted by a transmitting end is received, and the creating or updating message carries PDP context service quality parameters of a PDP context; and whether a bearing user plane tunnel corresponding to the PDP context can be packaged through a UDP-Lite protocol is judged according to the service quality parameters, and a response message carrying judgment result information is returned to the transmitting end so that the bearing user plane tunnel corresponding to the PDP context is packaged through the UDP-Lite protocol when the transmitting end receives the judgment result information indicating that packaging through the UDP-Lite protocol can be performed. According to the technical scheme, business of high wrong packet tolerance can be packaged into messages of the UDP-Lite protocol so that verification of the load of the messages can be reduced and data transmission efficiency can be substantially enhanced in comparison with the methods in the prior art.
