Problems solved by technology

[0004] Due to modeling requirements, when some parts are put into the hemming cavity, the angle between the part flange and the vertical direction will be less than 30°, which will cause the angle between the hemming pressure and the part flange to be much smaller than 30°. Will cause hemming quality problems

Abstract

The invention relates to an edge covering mechanism which comprises a bottom plate, a base fixed to the bottom plate, a pressing cutter and a die cavity arranged below the pressing cutter. The pressing cutter is connected with a driving device through a cutter rest, and a cutter rest support is arranged between the cutter rest and the base. An elongation part used for increasing the height of a cutter rest rotating point is arranged on the upper portion of the cutter rest support. The elongation part of the cutter rest support is in rotating connection with the middle of the cutter rest, and the lower portion of the cutter rest support is in rotating connection with the base. A locking mechanism is arranged between the cutter rest support and the base. The edge covering mechanism has the beneficial effects that the good edge covering effect and the process stability of parts of special profiles are guaranteed, and meanwhile the parts are prevented from intervening with the pressing cutter in the lifted process, so that the parts are automatically conveyed.

Description

Technical field [0001] The invention belongs to the technical field of automobile manufacturing, and specifically relates to a hemming mechanism. Background technique [0002] The edge wrapping mechanism in the prior art includes a main wrapping mechanism, a mold cavity, a bottom plate, and a driving device. Before the mechanism starts to work, the door flanging is pre-wrapped from the initial state to 45° by the pre-wrapping mechanism; then the pre-wrapping mechanism is opened, the main wrapping mechanism starts to move, and the main wrapping knife wraps the car door flaps to the inner and outer panels of the door. The main wrapping mechanism opens and the wrapping process ends. [0003] Hemming requirements: the angle between the hemming pressure and the part flanging is not less than 30°. When the angle between the hemming pressure and the part flanging is less than 30°, hemming quality problems will occur. [0004] Due to modeling requirements, when some parts are put into the ...
