Rapid cutter replacing and automatic clamping type numerically-controlled hydraulic flanging machine

Abstract

The present invention proposes a quick tool change automatic clamping CNC hydraulic edge folding machine, which includes a base body, an upper pressing mechanism, a lower pressing mechanism and an edge folding mechanism arranged on the base body, and the upper pressing mechanism is set on the upper part between the side brackets of the base body. Knife press mechanism, under the upper press knife mechanism, there is an upper press knife holder slider mechanism with upper press knife, the upper press mechanism can move up and down along both sides of the base body, and the upper press knife mechanism is equipped with quick tool change and automatic clamping devices; The lower pressing mechanism is to set the lower pressing knife fixing frame with the lower pressing knife between the base body side brackets under the upper pressing knife; , one end of the shaft is provided with a device capable of controlling the angle of rotation of the knuckle knife rotation shaft, and a knuckle knife fixing frame mechanism with a knuckle knife is arranged on the knuckle knife rotation shaft. The invention can bend workpieces of different widths into different bending shapes, has quick and convenient tool change, and has high precision, efficiency, quality and safety.

Description

technical field [0001] The invention relates to an edge folding machine, in particular to a numerically controlled hydraulic edge folding machine with rapid tool change and automatic clamping. Background technique [0002] At present, the bending machine is a widely used sheet metal bending equipment. Most enterprises related to sheet metal need to use the bending machine, which occupies an important position in the machinery industry. The bending machine is a mechanical device that uses the simplest general-purpose mold to bend metal sheets at various angles. Although this machine has many advantages, it has a series of defects: [0003] 1. During the entire bending process, the operator must hold the sheet and feed it manually. For large and heavy sheets, it is unsafe for the operator to work; [0004] 2. Due to the weight of the sheet metal, the bending angle will become larger, which will affect the bending accuracy; [0005] 3. It is difficult for one operator to comp...
