Problems solved by technology

[0004] After the existing CNC bending machine makes the finished product, due to the different wall thickness of some workpieces, the curved outer wall of the workpiece will cause cracks or even breaks during the deformation process of the workpiece. Therefore, it is necessary to inspect the processed c

Abstract

The invention discloses a local color change type numerical control bending machine product crack detection device, and belongs to the technical field of numerical control bending machine product detection equipment. The local color change type numerical control bending machine product crack detection device comprises a detection workpiece, a draught fan and a sealing piece, and the draught fan and the sealing piece are installed on the detection workpiece; the detection workpiece is sleeved with a detection sleeve, the upper end and the lower end of the detection sleeve are fixedly connected with elastic connecting films, the side walls, away from the detection sleeve, of the two elastic connecting films are fixedly connected with the same breathable film, a plurality of evenly-distributed elastic telescopic lines are fixedly connected between the breathable film and the detection sleeve, and the upper end and the lower end of the breathable film are fixedly connected with sealing rings. The device can detect workpieces processed by a numerical control bending machine, small cracks can be easily found by people while cracks can be detected, meanwhile, the device can detect two workpieces with different shapes, namely plates and round pipes, is very simple to use, and effectively improves the detection efficiency.

Description

technical field [0001] The present invention relates to the technical field of inspection equipment for digitally controlled bending machine products, and more specifically, to a crack detection device for local color-changing digitally controlled bending machine products. Background technique [0002] The CNC bending machine uses the equipped mold (general or special mold) to bend the metal sheet in the cold state into workpieces of various geometric cross-sectional shapes. It is a sheet metal forming machine designed for cold-rolled sheet metal processing, and is widely used in sheet metal bending processing in industries such as automobiles, aircraft manufacturing, light industry, shipbuilding, containers, elevators, and railway vehicles. [0003] There are also CNC bending machines designed for processing round tubular workpieces, also known as pipe benders, which need to heat the round tube workpieces during processing, and change the curvature of the round tube by chan...
