detailed description

Referring to Fig. 1, Fig. 2 and Fig. 3, a fully automatic continuous production line for door hinge leveling includes a main body of the production line operation platform 1, and a feeding device 2 is arranged on the main body of the production line operating platform 1, and the feeding device 2 is connected to a drive to move it. The driving mechanism 3, and the top of the feeding device 2 is provided with a leveling upper die mechanism 4, which is connected with a power mechanism that drives it to move up and down and level the door hinge material. The flat upper die mechanism 4 realizes the leveling of door hinge materials. This technical solution solves the problems of low product surface precision and low production efficiency in the prior art, and greatly improves product quality and production efficiency. At the same time, it also solves the problem of requiring a large amount of labor, and provides an automatic continuous production line for door hinge leveling with reliable product quality and high production efficiency.

Referring to Fig. 1, the drive mechanism 3 is a servo motor, the output shaft of the servo motor is connected with a reducer, the reducer is connected with the transmission mechanism, and the transmission mechanism is connected with the feeding device 2, the servo motor reducer is according to the instructions of the PLC control system Output the set speed and rotation angle, so as to change with the change of the set value, and respond to the control signal with a certain accuracy. The servo motor reducer drives the feeding device 2 through the sprocket mechanism.

Referring to Fig. 1, the power mechanism is a hydraulic press 5, and it is a four-column hydraulic press. Of course, the power mechanism of the present invention is not limited to the hydraulic press 5, and it can also be a hydraulic press, which can also achieve the same technical effect.

With reference to Fig. 1, Fig. 2, Fig. 3, this feeding device 2 is a chain feeding device, is provided with more than one chain 23 on the chain feeding device, preferably of the present invention is set to two chains 23, certainly also can according to need Different numbers of chains 23 are set, and the lower module 21 for transporting the door hinge material is arranged on the chain 23. The lower module 21 is provided with a card slot 22 suitable for the door hinge material. When the door hinge material is placed on the lower module 21, The slot 22 of the lower module 21 positions the door hinge material, and completes the feeding movement through the chain feeding device. After the material is sent to the detection device, the sensor detects the material and feeds back the signal to the PLC control system. At the same time, the sensor sends the material The distance signal to the center of the leveling upper die is fed back to the servo motor, and the servo motor realizes precise movement. After the positioning is completed, the movement stops. At this time, the hydraulic press 5 receives the system command and starts to move downward vertically, thus ensuring the circulation of the production line. Continuity improves production efficiency.
