Three-dimensional curved surface roll forming device

Abstract

The invention discloses a three-dimensional curved surface roll forming device, relates to plastic processing equipment for forming the curved surfaces of sheet metal parts and belongs to the field of mechanical engineering. The device mainly comprises at least one row of roll-in units (1) on the upper part, at least two rows of roll-in units (1) on the lower part, and a machine frame (2); each roll-in unit (1) consists of a work roll (9), a work roll driving mechanism, a work roll height adjustment mechanism and a support body (15); the work roll driving mechanism consists of a transmission shaft (16), a bevel gear transmission pair, and a worn gear and worm screw transmission pair; and the work roll height adjustment mechanism consists of a screw or a thread transmission pair. The three-dimensional curved surface roll forming device can change the processing mode of the conventional mould forming plates and the processing mode that the conventional rolling plate forming device can only process a two-dimensional curved surface, and an efficient continuous three-dimensional curved surface flexible forming device is provided.

Description

technical field [0001] The invention discloses a three-dimensional curved surface roll forming device, relates to a plastic processing equipment used for forming curved surfaces of plate parts, and belongs to the field of mechanical engineering. Background technique [0002] At present, the forming of three-dimensional curved panel parts is mainly realized through molds. Because each workpiece needs one or several sets of molds to complete, the design, manufacture, installation and debugging of molds consume a lot of manpower, material resources and time. The traditional coil forming device can only process simple curved parts whose generatrices are straight lines, such as cylindrical parts and conical parts, and it is difficult to process three-dimensional curved parts. Manual forming is mainly used to process large-size and small-batch parts, but its forming quality is poor, production efficiency is low, and labor intensity is high.

Because each workpiece needs one or several sets of molds to complete, the design, manufacture, installation and debugging of molds consume a lot of manpower, material resources and time

The traditional coil forming device can only process simple curved parts with straight lines, such as cylindrical parts and conical parts, and it is difficult to process three-dimensional curved parts

Manual forming is mainly used to process large-size and small-batch parts, but its forming quality is poor, production efficiency is low, and labor intensity is high

Chinese patent authorization announcement numbers CN100379501C, CN100398227C, CN100465993C and CN100999000B respectively disclose a three-dimensional curved surface flexible coiling device, a flexible forming device using bendable rollers to process cylindrical or rod-shaped three-dimensional workpieces, and a three-dimensional curved surface flexible coil with independently driven sub-rollers. Plate device and three-dimensional curved surface flexible forming device using bendable rollers, these devices can realize the flexible forming of three-dimensional curved surface, but the torque transmitted by it is small, and it can only form a plate with a small thickness
