Bending machine numerical control system device with embedded robot for control and method thereof

Abstract

The invention discloses a bending machine numerical control system device with embedded robot control and a method thereof. The bending machine numerical control system device comprises a numerical control system, a robot, a rack, a slide block control mechanism, a slide block, an upper mold, a lower mold, a charging frame and a discharging station, wherein the numerical control system is arranged on the rack; the robot is arranged on the rack; the slide block control mechanism is used for pushing the slide block to move up and down; the upper mold is mounted on the slide block; the lower mold is arranged under the upper mold; the lower mold is arranged on the rack; the charging frame is mounted at the left side of the rack; and the discharging station is mounted at the right side of the rack. The robot and bending machining are uniformly programmed and are subjected to synchronous motion control through the numerical control system, so that the robot becomes an embedded part of a numerical control bending machine and a rear bumper structure is cancelled; and the defects in the current market that the common numerical control bending machine and the robot are independently controlled and special software needs to be used for simulating a process of bending the robot so that the use complexity is caused are overcome.

Description

technical field [0001] The invention belongs to the field of electromechanical numerical control equipment, and specifically relates to a bending machine numerical control system device controlled by an embedded robot and a use method thereof. Background technique [0002] The actual application of robots in CNC bending machines is not common in the existing market. The reason is that the robot controller and the CNC system of the bending machine are independent control systems, but the shape of the workpiece will be changed during the bending operation, requiring robots Accurately follow the bending feed speed and trajectory of the bending machine, otherwise the following error will affect the bending accuracy and bending deformation process. In addition, because the process parameters such as positioning center, bending angle and mold shape are different for each bending, it is very difficult to calculate the path of the robot. [0003] In order to solve the problem of ro...

Problems solved by technology

[0004] The operation of this process is relatively complicated, and it is basically unusable for small batch sheet metal processing, and the efficiency is too low

[0005] In addition, the general-purpose bending machine robot is separated from the bending machine body. The distance between the origin of the robot coordinate system and the origin of the machine tool coordinate system needs to be obtained through detection and calculation, and the error is large. Every bending must pass through the backstop. The material mechanism assists in positioning the sheet metal to obtain accurate hemming length, which also affects the processing efficiency and increases the cost of the mechanism
