Dynamic self-adaptation control device for laser shot blasting forming precision of metal plate clamped by robot

Abstract

The invention relates to the field of machine manufacturing, in particular to a dynamic self-adaptation control device for laser shot blasting forming precision of a metal plate clamped by a robot. The dynamic self-adaptation control device is mainly composed of a laser device 1, a light guide and reflector path adjusting system 2, an impact laser head 3, a tool clamp movement system 4, a restraint layer jetting system 5, a dynamic optical monitoring system 6, an above control system, a central integration control system 7 and the like. A forming method of the dynamic self-adaptation control device is characterized in that laser beams emitted by the laser device 1 are transmitted into the laser impact head 3 through the light guide and reflector path adjusting system 2; the laser beams are adjusted and transmitted to the surface of the metal plate 18 clamped to the tool clamp movement system 4; the shot blasting surface of the metal plate 18 is covered with a restraint layer manufactured through the restraint layer jetting system 5, an energy absorption layer 22 absorbs lasers to generate impact waves in an induced manner to act on the surface of the plate; and the metal plate 18 generates fast plastic deformation or stress relief formation. According to the dynamic self-adaptation control device, three-dimensional impacts can be achieved, complex forming of large plates can be conducted, local micro forming can also be conducted, quantitative precise forming can be achieved, repeatability is good, and automatic production can be easily achieved.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a method and device for dynamic self-adaptive control of laser shot peening forming accuracy of metal sheets based on robot arm movement. The device is suitable for the forming of sheet metal, especially suitable for the forming of materials that are difficult or impossible to form by conventional methods, such as structural steel, titanium alloy, composite materials, etc. It can also be used for shape correction of rods and shell thin-walled parts . Background technique [0002] There are many plastic forming methods for sheet metal, including stamping forming, shot peening forming, explosive forming, digital progressive forming, moldless multi-point forming, etc. The most traditional and common stamping forming method has the disadvantages of high mold cost and long production cycle, and can only be used for low-carbon thin plates (such as 1Cr18Ni9Ti, 10F, 20, etc.), al...

Problems solved by technology

However, in this method, the front and back surfaces of the workpiece need to be pasted with flexible films to form an integrated transparent constrained layer and energy absorbing layer. Especially when running water is used as the transparent constrained layer, this will not be conducive to the detection and feedback system to dynamically monitor the deformation of the sheet. situation, to achieve real-time dynamic detection
