Automatic edge curling device of steel door sheet

Abstract

The invention discloses an automatic edge curling device of steel door sheet; the automatic edge curling device of steel door sheet comprises a machine frame, a roller group, a feeding platform and a discharging platform; the feeding platform comprises a frame body, a fixed baffle, a movable cross beam, and a movably stop block; the fixed baffle is mounted on the upper end of the frame body; the movably stop block is mounted on the movably cross beam; the distance between the fixed baffle and the movably cross beam can be adjusted by rotating a lead screw; the upper and lower compression rollers in the roller group are both coaxially provided with gears, and the two gears are mutually engaged; a transmission gear is respectively installed among coaxial gears of a plurality of upper compression rollers; an intermediate roller group is installed above the machine frame; the intermediate roller group is used for driving the door sheet to move and used for ensuring the flatness of the door sheet in the edge curling movement process; a gap is arranged between the upper and lower intermediate rollers of the intermediate roller group; each lower intermediate roller is coaxially mounted with a corresponding lower compression roller. The device reduces the wear rate of the upper and lower compression rollers, so as to make the door sheet be uniformly stressed, and make the machining smooth, thereby ensuring the edge curling quality of the door sheet, and saving the machining cost of the enterprises.

Description

technical field [0001] The invention relates to a steel door panel processing equipment, in particular to an automatic curling device for a steel door panel. Background technique [0002] The existing steel door panel crimping device is generally composed of a frame, a roller group for crimping the panel, a loading platform and an unloading platform. Gradually hem one side of the panel to shape. [0003] Among them, the feeding platform in the existing equipment is just a simple support platform for supporting the panel to be processed, and there is no limit device for the panel. stage), so that the panel is easy to deviate only under the drive of the roller group, the produced panel is unqualified, and more waste is produced, resulting in waste and increasing the cost of the enterprise.

Problems solved by technology

[0003] Among them, the feeding platform in the existing equipment is just a simple support platform for supporting the panel to be processed, and there is no limit device for the panel. stage), so that the panel is easy to deviate only under the drive of the roller group, the produced panel is unqualified, and more waste is produced, resulting in waste and increasing the cost of the enterprise

[0004] Only one of the upper and lower pressure rollers in the existing equipment is a rotating wheel. This structure is more laborious when driving the panel to move and curling the panel, which improves the wear rate of the upper and lower pressure rollers and reduces equipment lifespan

[0005] Existing equipment often only relies on the roller group to pull and move the panel. Since the roller group only acts on one side of the panel, the force on the panel is uneven. During the travel of the panel, the panel is easy to deviate, resulting in incomplete and uneven panels.
