Real-time automatic measuring device for bending angle of bending machine

Abstract

The invention discloses an automatic real-time measurement device for a bending angle of a bending machine and aims to solve the technical problems of steel wire flexible deformation, inaccurate transmission and the necessity of extra mechanism for backing to an initial state, in case of a conventional bending angle measurement device in the prior art. The technical scheme adopted is that the device provided by the invention comprises an upper die, a lower die and a workpiece, and further comprises a base and at least one bending angle measurement device body on the base, wherein the bending angle measurement device bodies and the lower die are fixed on the base; the bending angle measurement device bodies are positioned between the lower dies. The measurement device body, in the initial state, comprises a saddle fixed on the base, a guide rod fixed on the saddle, a left half part and a right half part both arranged on the guide rod in a sliding manner, and a tension spring connecting the left half part and the right half part. The device provided by the invention has the advantages that a link mechanism is adopted for accurate transmission, and self-return under the action of gravity is realized; and the bending angle of the overall workpiece is measured in a way of measuring the bending angles of two sides of the bended piece at the same time. Therefore, the automatic measurement device is simple, accurate in transmission, and easy to realize.

Description

technical field [0001] The invention relates to a real-time automatic measurement device for the bending angle of a bending machine, in particular to a real-time automatic measurement device for the bending angle of the bending machine used for bending plate-shaped metal materials. Background technique [0002] Bending machine is a kind of equipment used for bending plate-shaped materials. The bending principle is to place the workpiece on the plane of the lower die. When the upper die presses the lower die, the workpiece forms a fold under the action of the pressure and the upper and lower dies. bend angle. When bending workpieces (such as sheet metal parts), how to precisely control the bending angle of the workpiece is the bending machine performance that both bending machine manufacturers and application companies must pay attention to. At present, there are many methods for measuring the bending angle of bending machines, and some of these methods have solved the probl...
