The controlling device comprises a PLC, a motor controller, an encoder, an induction contact head and a display. A motor is connected with the motor controller. The motor controller is connected with the PLC. The PLC controls whether the motor rotates or not through the motor controller according to received signals. The automated folding-type corner protecting ring producing line has the advantages that 1, uneven forming and angular deviation caused by the unstable speed of a steel belt during traditional single-machine operation are avoided; 2, the punching machine and the servo shearing machine are arranged on a servo base, it is ensured that shapes of punched holes and shearing sizes which are fit for the standard can be still formed during the steel belt moving; and 3, position interference between the first-formed end surface of a corner protecting ring and a bending wheel is avoided through a spiral placing table.

A heavy-type inverted studded thread bolt mounting tooling and a use method of same. The tooling includes: a sling frame, which is provided with a main beam, a sub-beam at one side of the main beam, ajoint which is arranged on the middle of the other side of the main beam and is extended, and a clamping plate arranged on the outer end of the joint. Sling holes, which are arranged in an isoscelestriangle shape, are formed in two ends of the main beam and the sub-beam. The top ends of the sling holes arranged in the isosceles triangle shape are located on the outer end of the sub-beam and arelocated at the extension line of the central line of the joint. A clamping thread hole, which is matched with the structure of a to-be-mounted inverted studded thread bolt, is formed on the outer endof the clamping plate. When the sling frame is under an idle or loaded status, the gravity of one side of the is larger than that of one side of the joint with the sling frame as the central line, sothat the sling gravity is located between the sling holes, which are arranged in an isosceles triangle shape, between the main beam and the sub-beam. The structure effectively overcomes position interference of a sling hoisting rope and corresponding equipment parts, and ensures that the inverted studded thread bolt can be maintained to be balanced, stable and safe during the slinging and moving processes.
