Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal bending, in particular to a sheet metal bending mechanism. Background Art

[0002] In the prior art, rolling shutter doors are connected in series with multi-jointed movable door panels. In a fixed slideway, the doors rotate up and down with the reel above the door as the center. During the production process of rolling shutter doors, sheet metal parts need to be processed. Sheet metal has the characteristics of light weight, high strength, conductivity, low cost, and good mass production performance. It has been widely used in sheet metal processing. One of the processes is to bend the sheet metal parts. The sheet metal parts are bent into a certain angle by bending so that they meet the size specifications required for the production of rolling shutter doors.

[0003] The sheet metal bending devices on the market generally use a bending head with a sharp part to bend the sheet metal after bending the sheet metal many times. However, after the bending head has bent the sheet metal many times, metal fatigue will occur in the bending head, resulting in wear and tear, which affects the bending accuracy. Therefore, the present application proposes a sheet metal bending mechanism, which is convenient for quick replacement of the bending head when it needs to be replaced, thereby enhancing the convenience of using the bending mechanism and the bending accuracy. Utility Model Content

[0028] A lifting column 11 is installed on the top outer wall of the hydraulic assembly 14 , and the lifting column 11 slides on the inner walls of the mounting plate 12 and the fixing block 13 .

[0029] The lifting column 11 is installed with a fixed support 17 through a rotating shaft. A waist-shaped hole is provided on the outer wall of one side of the fixed support 17. The inner wall of the waist-shaped hole is rotatably installed on the circumferential outer wall of the lifting column 11 through a fixed shaft 10. The inner wall of the other end of the fixed support 17 is installed on the outer wall of the connecting column 9 through a rotating shaft.

[0030] By providing a hydraulic component 14, the bending head 21 provided in the device requires a heavy mechanical mechanism to lift. The lifting column 11 is then lifted up by the hydraulic pressure of the hydraulic component 14, and the bending head 21 is lifted up by the force of the lifting column 11. Then, the lifting column 11 is retracted by the contraction of the hydraulic component 14, which further enhances the practicality of the device.

[0037] By providing the anti-skid film 6, when the sheet metal is placed on the top outer wall of the lever platform 4, the sheet metal placed on the top outer wall is further fixed by the limiting function of the anti-skid film 6, thereby protecting the outer wall of the lever platform 4, thereby further enhancing the safety of the device.

[0038] Working principle:

[0039] When using the device, first place the sheet metal to be bent on the top outer wall of the lever platform 4, then slide the lever platform 4 to a suitable position, then start the hydraulic assembly 14 to start extending and retracting, and by raising the lifting column 11, the bending assembly 7 begins to fall, and then the bending head 21 provided in the bending assembly 7 bends the sheet metal, and then the bending assembly 7 is lifted by contraction of the hydraulic assembly 14, thereby completing the bending of the sheet metal. However, the accuracy of the bending head 21 will decrease after multiple bendings, and then unscrew the bolts on the outer wall of the disassembly assembly 19, pull the handle 20, slide the bending head 21 on the inner wall of the disassembly assembly 19 to take it out, and then replace it with a new bending head 21 to complete the convenient replacement of the bending head 21 of the device.
