Embodiment Construction

[0023] Such as figure 1 with figure 2 As shown, a method for manufacturing an elevator hemming plate is made using a single-arm stretch-bending machine. The single-arm stretch-bending machine includes an arc mold, a rotating shaft that drives the mold to rotate, a driving gear mounted on the rotating shaft 1, and The rack 2 is matched with the driving gear. The rack 2 is equipped with a first clamp 3 for clamping the end of the flange 5 and a second clamp 4 for supporting the bottom of the flange 5; the process steps include:

[0024] 1) Install and fix the head end of the flange 5 on the mold, the first clamp 3 clamps the end of the flange 5, and the second clamp 4 clamps the middle of the flange 5;

[0025] 2) The rotating shaft 1 drives the mold to rotate, and the folding plate 5 is initially stretched and bent;

[0026] 3) When the folding plate 5 is bent and turned to a predetermined angle, the shaft 1 stops rotating, and the second clamp 4 is removed, and the third clamp is in...

Abstract

The invention discloses a method for manufacturing an elevator flanged plate through a one-armed draw bender. The method comprises the process steps that the head end of the flanged plate is installed on and fixed to a die, a first fixture clamps the tail end of the flanged plate, and a second fixture clamps the middle of the flanged plate; a rotary shaft drives the die to rotate so that the flange plate can be subjected to preliminary draw bending forming treatment; the rotary shaft stops rotating, the second fixture is disassembled, and a third fixture is installed at the joint of a tabulate part and a bending forming part of the flanged plate and is used for preventing the flanged plate from being arched and deformed; the rotary shaft drives the die to rotate till draw bending forming of the flanged plate is completed; and the flanged plate is disassembled. According to the method for manufacturing the elevator flanged plate, the elevator flanged plate is produced through the one-armed draw bender, so that the production cost is significantly reduced.

Description

Technical field [0001] The invention relates to a manufacturing method of an elevator folding plate. Background technique [0002] In the prior art, a double-arm stretch-bending machine is generally used for the production and processing of the elevator flange plate, and the double-arm stretch-bending machine has a complicated structure and expensive equipment, resulting in higher production cost of the elevator flange plate. Summary of the invention [0003] The present invention aims to solve the above-mentioned technical problems, and provides a manufacturing method of using a single-arm stretch-bending machine to produce elevator flanges, and the production cost is low. [0004] The present invention is realized through the following technical solutions: [0005] A method for manufacturing an elevator hemming plate is made by using a single-arm stretch-bending machine. The single-arm stretch-bending machine includes an arc-shaped mold, a rotating shaft that drives the mold to rot...
