5, inspect punching finished product in the punching out process at any time by random samples, it is positioned in the qualified stacked punching of step 4 gained punching groove position degree, and make the punching keyway of punching finished product and the punching keyway of stacked punching be in same position, whether metering system described in 4, the method that compares to determine to detect the punching groove position degree of punching finished product qualified set by step.
In addition, when carrying out the degree detection of punching position with detection method of the present invention, require punching to be checked necessary smooth,, can punching groove one side that will detect in the punching to be checked be pressed in stacked punching with hand if there are distortion in the poor flatness of punching to be checked or tooth portion.
Compared with prior art, the present invention consider one-shot groove mould processing technology with the punching groove consistent with punching keyway center line, and adjacent two grooves be low water, and the driving error of notching press concentrates on this three-flute, therefore, after each installation mold carries out the initial workpiece punching out, three coordinate inspections are carried out in the initial workpiece punching, whether correctly installed with explanation mould, positioning tool; On the qualified basis of initial workpiece punching, continue several pieces punchings of punching out, and be configured to the simple detection device of trough position degree by register pin, so that inspect the punching finished product in the punching out process at any time by random samples, whether the checking mould is loosening, whether kinematic train needs to adjust; In armature stamping punching out process the trough position degree of punching is inspected by random samples termly, in time notching press, moulds of industrial equipment are adjusted, guarantee that the punching trough position degree satisfies the drawing requirement, it is neat, consistent to make iron core laminate flute profile.
The present invention detects accurately, and reliable high, efficient and convenient, cost is low, and the efficient height is applicable to that the position degree of one-shot groove mould processing technology punching out punching detects.
