Description

Technical Field

[0001] The utility model relates to the technical field of feeding compensation, in particular to a combined type feeding accuracy compensation device for a press line. Background Art

[0002] The feeding accuracy compensation of the stamping line is based on the comparison between the actual feeding size and the standard feeding size required, and is adjusted through the external control system. When feeding, the material plate is first limited by adjusting the distance between the limit block and the limit plate to prevent the material plate from deflecting during transportation. When accuracy compensation is required, the cylinder controls the wheel to descend so that the wheel contacts the surface of the material plate, and then the external control system adjusts the motor speed according to the error analysis, and then controls the number of rotations of the wheel to push the material plate to move and perform accuracy compensation for the feeding error.

[0003] At present, the feeding accuracy compensation equipment of the stamping line adopts a single feeding wheel to compensate the feeding. For the feeding of large-width workpieces, the compensation feeding is unbalanced, which increases the difficulty of accurate feeding, and the feeding compensation adaptability of different types of workpieces is poor.
