Iron accessory multi-angle bending method

Abstract

The invention relates to an iron accessory multi-angle bending method. The method comprises the following steps that angle adjustment is conducted, and a pin is inserted into a corresponding limiting hole according to the bending angle so as to change the height of a limiting frame matched with the pin on a support; an iron sheet a is bent, a fixing plate moves downwards, pressing plates make contact with the iron sheet a, and then ejector rods drive the pressing plates and bottom plates to rotate at the same time to bend the iron sheet a till the bottom plates abut against the limiting frame; bending and pressure maintaining are conducted, the fixing plate continues to move downwards, the ejector rods rotate, and the ends move along the upper surfaces of the pressing plates; an iron sheet b is welded, a transmission assembly a acts to drive a swing arm to rotate, a gripper places the iron sheet b on the iron sheet a, and then the iron sheet a and the iron sheet b are welded to form an iron accessory; a welded part is demolded, the fixing plate moves upwards, the pressing plates and the swing arm rotate and reset, and then a roll shaft rotates to drive the iron sheet a to move to the bottom plate and eject the iron accessory away; and the iron sheet b is fed, and an air cylinder drives the iron sheet b to be clamped into the gripper. By means of the iron accessory multi-angle bending method, continuous production of the iron accessory can be achieved.

Description

technical field [0001] The invention relates to the technical field of production of iron tower accessories, in particular to a multi-angle bending method for iron accessories. Background technique [0002] Sheet metal is a comprehensive cold working process for thin metal plates (usually below 6mm), including shearing, punching / cutting / compositing, folding, welding, riveting, splicing, forming (such as automobile body), etc. Its distinctive feature is the same The thickness of the parts is the same. The products processed by the sheet metal industry are called sheet metal parts. The sheet metal parts used in different industries are generally different. They are mostly used for assembly. The sheet metal parts are the products of the sheet metal process. Demand, different parts need to be welded on the sheet metal parts. [0003] The invention patent with the Chinese patent application number CN201910806756.8 discloses a rapid bending and forming device for multi-angle shee...

AI Technical Summary

Problems solved by technology

[0005] In view of the above problems, the present invention provides a multi-angle bending method for iron accessories, which drives the bending assembly and the positioning assembly to rotate to bend the iron sheet a through the downward movement of the fixed plate, and then the fixed plate continues to move downward to perform bending on the iron sheet a. At the same time, under the action of the transmission component a, the swing arm rotates so that the iron piece b and the iron piece a are spliced, and the two are fixed by welding. Finally, in the process of moving the fixed plate, under the action of the transmission component b, The rotation of the roller shaft realizes the feeding of the iron sheet a and at the same time enables the output of the iron accessories, which solves the technical problem of low bending efficiency in the prior art
