Bending machine

Abstract

The invention belongs to the field of bending devices, and provides a bending machine. The bending machine comprises a machine frame, a lower cutting board, an upper cutting board, a rear material blocking assembly and an electronic scale connecting block, wherein a bending opening is formed in the machine frame, the lower cutting board is positioned at the lower side of the bending opening and isconnected with the machine frame, the upper cutting board is positioned on the upper side of the bending opening and is in sliding connection with the machine frame, the rear material blocking assembly is arranged in the machine frame, one end of a stop block is located on one side of the lower cutting board, and the lower end of the electronic scale connecting block is connected to the lower side end of the machine frame. Compared with the prior art, the bending machine has the advantages that when the bending machine bends a board, an electronic scale is not affected by the lower pressure,and therefore the measurement precision is improved, the descending distance precision of the upper cutting board can be improved, and the bending precision of the board can be increased; and the rearmaterial blocking assembly can be adjusted according to the lengths and bending depths of the different boards, so that the universality of the bending machine is improved.

Description

technical field [0001] The invention belongs to the field of bending devices, and in particular relates to a bending machine. Background technique [0002] A bending machine is a machine that can bend plates. Bending machines are divided into manual bending machines, hydraulic bending machines and CNC bending machines. Manual bending machines are divided into mechanical manual bending machines and electric manual bending machines. Bending machine, hydraulic bending machine can be divided into: torsion shaft synchronization, machine-hydraulic synchronization and electro-hydraulic synchronization according to the synchronization mode. Most of the bending machines in China are hydraulic bending machines, but the traditional hydraulic bending machines have many disadvantages: 1. The bending accuracy is low and cannot meet the high-precision requirements; 2. The bending efficiency is low and cannot keep up with the production rhythm; 3. After the bending machine is used for many...

[0002] A bending machine is a machine that can bend plates. Bending machines are divided into manual bending machines, hydraulic bending machines and CNC bending machines. Manual bending machines are divided into mechanical manual bending machines and electric manual bending machines. Bending machine, hydraulic bending machine can be divided into: torsion shaft synchronization, machine-hydraulic synchronization and electro-hydraulic synchronization according to the synchronization mode. Most of the bending machines in China are hydraulic bending machines, but the traditional hydraulic bending machines have many disadvantages: 1. The bending accuracy is low and cannot meet the high-precision requirements; 2. The bending efficiency is low and cannot keep up with the production rhythm; 3. After the bending machine is used for many times, the bottom plate will be deformed due to the force; 4. The positioning is not accurate, and one bending machine can only be used for one kind of plate
