Numerical control full-servo bending machine

Abstract

The invention relates to a numerical control full-servo bending machine, which comprises a machine frame, a numerical control device, a transmission device, a sliding device, a back material retaining device and a worktable, wherein the transmission device, the sliding device, the back material retaining device and the worktable are arranged on the machine frame, the transmission device is connected with the sliding device, the worktable is arranged opposite to the sliding device, the back material retaining device is arranged at one side of the worktable, and the numerical control device is fixedly arranged on the machine frame, and is respectively connected with the transmission device and the back material retaining device. The numerical control full-servo bending machine has the advantages that the servo motor drives a screw rod to rotate, so when the transmission device performs transmission, the action precision and stability are improved; the sliding device consists of an X-shaped guide rail and a V-shaped slide block which are matched, so the contact surface of the guide rail and the slide block is increased, a higher position precision can be guaranteed under the condition of larger force bearing, and condition of rail deviation does not easily occur; the action of the back material retaining device is controlled by the numerical control device, so the manual operation is reduced, and the action precision and working efficiency are improved According to the numerical control full-servo bending machine the working precision is improved, and the product quality and stability are further improved.

Description

technical field [0001] The invention relates to a metal plate processing equipment, in particular to a numerically controlled full-servo bending machine. Background technique [0002] A bending machine is a device capable of bending sheet metal. The traditional bending machine mainly includes a transmission device, a sliding device, a material blocking device and a worktable. The transmission device is used to generate power and drive the sliding device to move. A fixture for clamping the tool is installed on the sliding device. At the same time, the working table and the fixture Relatively arranged, the stopper device is used to locate the metal sheet to be processed, and when working, driven by the sliding device, the cutter presses the metal sheet to make it bend. [0003] The defects of the traditional bending machine are: the transmission device is mainly hydraulic transmission, the viscosity of the hydraulic oil in the hydraulic transmission system is affected by the ...

AI Technical Summary

Problems solved by technology

[0003] The defects of the traditional bending machine are: the transmission device is mainly hydraulic transmission, the viscosity of the hydraulic oil in the hydraulic transmission system is affected by the temperature, resulting in unstable movement speed, once there is air infiltration, there will be uneven beating

The sliding device uses rollers to cooperate with giant guide rails. This kind of line-to-surface contact mode will cause overload and over-deflection under the influence of pressure when the bending machine is working.

The stopper device needs to realize the up and down, left and right and front and back positioning of the metal sheet, while the up and down, left and right displacement settings of the stopper device in the traditional bending machine must be manually adjusted by the operator, and its accuracy is difficult to guarantee

[0004] The above problems lead to the problem of low precision of the traditional bending machine, which leads to the decline or unevenness of the product quality
