Profile bending machine

Abstract

The invention relates a profile bending machine. The profile bending machine comprises a machine body, a working roll device, carrier roll devices and a transmission system, wherein the transmission system is connected with the working roll device and the carrier roll devices to provide power; three working rolls of the working roll device are driving rolls; and telescopic cylinders installed in working roll shaft sleeves drive molds at the front ends of the working rolls to make telescopic movement. According to the profile bending machine, through matched movement of the carrier roll device and the working roll device, a plurality of types of profiles can share one machine, the machining accuracy is high, the equipment size is small, and operation is convenient.

Description

technical field [0001] The invention relates to the field of profile bending machines, in particular to a profile bending machine which can be used for processing various profiles. Background technique [0002] Type bending machine is a kind of high-school processing equipment for bending aluminum alloy profiles, flat steel, square steel, round steel, angle steel, I-shaped steel, H-shaped steel, square tube, rectangular tube, round tube and other profiles. The bending process is Continuous elastic-plastic bending with a certain stretch, less springback, accurate forming, high bending quality, high work efficiency, and low cost of use. Equipped with auxiliary devices, it can roll tapered parts and realize bending of pipes and profiles. roll. Therefore, the type bending machine is widely used in automobile, elevator, boiler, shipbuilding, petroleum, chemical industry, hydraulic engineering, metal structure, machinery manufacturing and other industries. [0003] The so-called...

Problems solved by technology

The commonly used three-roller bending machine can be divided into four structural forms according to the movement mode of the three working rolls: symmetrical upward adjustment type, upper roll cross movement type, horizontal downward adjustment type, and arc downward adjustment type; the symmetrical upward adjustment type has a simple structure but cannot be pre-bended; The roller cross movable type can be pre-bent, the oil cylinder is small, the oil cylinder is placed on the top, light weight, high center of gravity, suitable for small and medium-sized machines; the horizontal downward adjustment type can be pre-bent, not only can roll thin workpieces, but also can roll thick walls Large tube workpiece, but its oil cylinder is larger, the oil cylinder is placed below, the center of gravity is low, and the weight is heavy; the arc downward adjustment type can be pre-bent, and can roll thin-walled and small-diameter workpieces. The structure is compact and more complicated.

Since different profiles and workpieces with different processing requirements need to be processed by different types of bending machines, and the work rolls of the bending machines currently on the market can only rotate and move in a plane, if you want to process workpieces with different specifications, sizes and shapes , need to replace different molds, the operation is cumbersome and cannot be completed on the same equipment
