Abstract

The invention discloses a pre-bending cutter and an edge wrapping device. The pre-bending cutter comprises a connecting part and a cutter head connected with the connecting part; and the bottom of thecutter head is sunken inwards to form a bent cambered surface. The edge wrapping device comprises an upper die, a lower die, a driving block assembly connected with the upper die and a pre-bending device connected with the lower die; the pre-bending device comprises a driving device connected with the lower die, and the above pre-bending cutter; a first roller and second rollers are arranged on the driving device; the driving block assembly comprises a first driving block and second driving blocks; when the driving block assembly descends, the first driving block is in contact with the firstroller and applies pressure to the first roller, so that the driving device drives the pre-bending cutter to rotate downwards; and when the pre-bending cutter rotates to a certain angle and is in contact with a plate body, the second driving blocks are in contact with the second rollers and apply pressure to the second rollers, so that the driving device drives the pre-bending cutter to carry outpre-bending machining on the edge of the plate body.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a pre-curved knife and an edge wrapping device. Background technique [0002] With the improvement of living standards, cars have become a necessary means of transportation at home. In the automobile production process, the hemming process of the outer body cover is a common processing method. Generally speaking, the automobile engine cover assembly is to pre-turn and turn over the edge of the outer plate of the engine cover through the hemming die, and finally obtain the hemming assembly. [0003] With the individual demand, the requirements for the shape of the outer panel of the engine cover are improved. In order to prevent the inner and outer plates from interfering when merging, usually an additional suction cup is used to apply external force to the outer plate during merging, and the outer plate is forced to open slightly under the action of the external force.
