Embodiment Construction

[0024] Below, refer to figure 1 as well as figure 2 , the cutting device 1 which is one embodiment of the cutting device according to the present invention will be described.

[0025] The cutting device 1 is a device for cutting a workpiece W that is a steel plate.

[0026] Such as figure 1 As shown, the cutting device 1 includes a lower mold 10 , a robot 20 , a nibbling machine 30 , and a control device 40 .

[0027] The lower die 10 is a member on which the workpiece W is placed, and is configured to be able to fix the workpiece W. As shown in FIG.

[0028] The robot 20 has a multi-joint arm, and is configured to be able to change the position and posture of the arm. A nibbling profiler 30 is attached to the front end of the arm of the robot 20 .

[0029] Such as figure 2 (a) and figure 2 As shown in (b), the nibbling contour machine 30 is a device that continuously punches the workpiece W while moving, and includes a housing 31 , a punch 32 , a support portion 33 ...

Abstract

Provided is a technology whereby the life of a punch provided in a nibbler can be extended. A cutting device (1) for cutting workpieces (W), comprising: at least one robot (20) having an arm capable of changing position and posture; a nibbler (30) attached to the tip of the robot (20) arm and having a punch (32) that punches out workpieces (W) by reciprocally moving in the vertical direction; and a control device (40) that controls the robot (20) and the nibbler (30). The nibbler (30) is moved by the robot (20) and cuts workpieces (W) by continuously punching out the workpieces (W) by using the punch (32). The control device (40) has: a robot control unit (40a) that controls the robot (20) such that the nibbler (30) travels at a speed corresponding to the shape of the nibbler (30) travel path; and a punch control unit (40b) that changes the frequency of the punch (32).

Description

technical field [0001] The present invention relates to a cutting device and a cutting method for cutting a steel plate. Background technique [0002] Conventionally, a nibbler is widely known as a cutting device for cutting a steel plate. [0003] In general, a nibbling contour machine includes: a cylindrical casing; a punch disposed inside the casing; and a die disposed below the casing, and the nibbling contour machine uses the punch while moving. The head continuously punches the steel plate supplied between the housing and the die to cut the steel plate. [0004] Patent Document 1 discloses a hand-held nibbling profiler configured to cut a steel plate by being held and moved by an operator. [0005] On the other hand, it is also possible to attach the nibbling contour machine to the robot. [0006] When the nibbing machine is attached to the robot, the robot is controlled so that the nibbing machine moves along a preset path. [0007] When the nibbing machine is mov...
