Arc-shaped door core plate bending device

Abstract

The invention relates to the technical field of plate processing, and particularly discloses an arc-shaped door core plate bending device. The bending device comprises a plurality of compression roller assemblies which are arranged at equal intervals and are sequentially hinged, and telescopic devices used for adjusting the hinge angles between adjacent compression roller assemblies; each telescopic device comprises a fixed block, a limiting frame, a sliding block and a connecting rod, wherein the fixed block and the limiting frame are fixed at the bottom of the compression roller assembly, and the sliding block is in sliding connection with the limiting frame; the fixed block at the bottom of each compression roller assembly is connected with the sliding block at the bottom of the adjacent compression roller assembly through the corresponding connecting rod; and the fixed block and the sliding block at the bottom of one outermost compression roller assembly are connected with drivingrods. Compared with a traditional arc-shaped die bending mode and a traditional arc rolling bending mode, the bending device can control the strokes of the driving rods to change the retraction degrees of the telescopic devices so as to change the bending radius of a door core plate, if the bending device is used for processing the plates with different bending radii, the cost of repeatedly opening a die is saved, and the bending device has the characteristics of being convenient and fast to operate, wide in application range and low in equipment cost.

Description

technical field [0001] The invention relates to the technical field of plate processing, in particular to a plate bending equipment. Background technique [0002] In order to meet the needs of customers in some markets, curved doors are also an indispensable product in furniture companies, but in the production process of curved doors, the production of curved door core panels is more troublesome. [0003] The production process of arc-shaped door core board needs to be processed by bending. There are two main traditional bending processes. One way is to first carve out the arc-shaped mold according to the required arc, and then clamp the core board through the mold to make it bend and shape , this method is too cumbersome to operate, and the radian cannot be adjusted. Different radians need to open different molds, resulting in a lot of material waste; another processing method is to use three rollers to roll the door core board into an arc-shaped board through an arc rolli...

[0003] The production process of arc-shaped door core board needs to be processed by bending. There are two main traditional bending processes. One way is to first carve out the arc-shaped mold according to the required arc, and then clamp the core board through the mold to make it bend and shape , this method is too cumbersome to operate, and the radian cannot be adjusted. Different radians need to open different molds, resulting in a lot of material waste; another processing method is to use three rollers to roll the door core board into an arc-shaped board through an arc rolling machine. The arc roller machine is custom-made, and the radian is still not adjustable, so this solution provides a device that can adjust the radian arbitrarily to realize the bending and shaping of the core plate
