The work to be prepared before testing a new mold for high-precision metal stamping parts: the use of the material for the mold test, the adjustment of the mold adjustment sliders to the outermost, so as not to damage the mold, the selection of the mold test machine: the parameters considered are tonnage, Accuracy, stroke, size of working surface, size of blanking hole, height of formwork, difficulty of machine adjustment, etc.

Precision metal stamping parts mold test mold, set mold: ensure that there is no waste and other sundries on the work surface of the punch press and the mold seat; the mold should be in the center of the work surface and parallel to the work surface; the mold should be fastened to the work surface of the punch press and the upper slider It should be firm; at the same time, adjust the closing height to a gap of 0~0.05mm. Feeding: Manual feeding is used for the initial feeding. First pass the material strip through the mold once (except for the guide plate type), after positioning the material strip with the side roller of the feeder, take out the material strip, and then send the material strip to the punching process hole station and the first Punch down between the positioning pins (but not to force the unilateral cutting of the knife edge), and then use the positioning pins to align with the positioning holes for precise positioning, and feed one by one. When feeding, carefully observe the abnormalities during feeding, such as belting, blocking, etc. Material, not enough flash, etc. Mold adjustment and maintenance: Firstly, eliminate the obstacles that affect the continuous feeding of the continuous stamping die, such as belt material, material jam, material blocking, etc. Secondly, solve the problems that affect the appearance of the product: chip skipping, indentation, mold marks, napping, insufficient flashing, etc., and at the same time deal with the problem of material blocking; finally adjust and repair the size parameters, function parameters and assembly parameters of the product. According to the adjustment and maintenance status during the mold trial, fill in the mold trial report truthfully, and correct the mold drawing.

Sample production and measurement, sample production: manual feeding or automatic feeding to produce the required quantity in terms of size, appearance, function, and assembly. Sample measurement: measure the sample size and functional parameters according to the product blueprint, and fill in the independent inspection record.

Finally, the independent inspection record of the sample, the assembly of the mold test report, and the revised mold drawing are submitted to the design project. This is the process of testing new molds for Jingtian precision metal stamping parts.
