ROLLER HEMMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18189227 titled 'ROLLER HEMMING APPARATUS
Simplified Explanation
The roller hemming apparatus described in the patent application aims to prevent misalignment of a lower plate workpiece during the bending process.
- The apparatus includes a die that holds a first workpiece, which is a plate material, and a roller that bends the edge of the first workpiece onto the edge of a second workpiece, which is also a plate material.
- The die is equipped with a suction mechanism that opens towards the workpiece contact surface, where the hem flange on the first workpiece abuts.
- The suction mechanism suctions the first workpiece, ensuring that it remains in the correct position during the hemming process.
- By preventing positional misalignment, the apparatus improves the accuracy and quality of the hemming process.
Original Abstract Submitted
Provided is a roller hemming apparatus capable of preventing positional misalignment of a lower plate workpiece during a bending process. A roller hemming apparatus of the present disclosure includes a die configured to hold a first workpiece which is a plate material, and a roller configured to bend an edge of the first workpiece onto an edge of a second workpiece, which is a plate material placed on the first workpiece held in the die, to overlap each other, the die including a suction mechanism that opens toward a workpiece contact surface against which a hem flange on a peripheral edge of the first workpiece abuts, and that suctions the first workpiece. Thus, positional misalignment of the first workpiece is prevented during a hemming process.
