Forging geometry shape and size of the inspection

Forgings length inspection available ruler, calipers, gauge or measure vernier caliper, universal measuring tool. Forgings height ( Or lateral size) With diameter inspection usually measured with calipers and vernier caliper, such as large volume, available special limit card board measurement. Forgings thickness inspection is usually measured with calipers and vernier caliper, if the production batch is big, can be used with fan outside calipers to measure scale. Forging of cylindrical and radius radius of inspection available template or outer radius, inner radius of the limit sample measurement. Forgings on Angle Angle on the test of forgings, available goniometer is measured. Forgings aperture tests ( 1) If there is no slope, hole were measured with vernier, caliper can be used to measure. ( 2) If there is a slope hole, production batch is big, usable limit gauge measurement. ( 3) If the aperture is large, the large scale available vernier caliper, or use the sample inspection. Forgings dislocation inspection ( 1) If the forgings on the parting surface and there are 7 - higher than that of end face 10 degrees slope, the mold or the parting surface position in the middle of the forgings ontology, before trimming can be observed if there is a mismatch of forgings. ( 2) Such as dislocation not easily observed, the forgings can be fixed at the lower and the upper line inspection, or use a templet inspection. ( 3) Forgings for circular cross section of, can use vernier calipers measure the diameter of the parting line error. Forgings deflection test (diameter 1) For cross section of long axial forgings, such as on the tablet, diffuse slow rotary forging again and again. You can measure the maximum deflection of the axis. ( 2) Put forgings both ends a special data of the v-shaped blocks or rolling rods, rotary forging, through the instrument can measure the maximum deflection of forging between the two fulcrum. Forging plane perpendicularity test if you want to test forgings on one end, Such as flange) And forging axis perpendicularity, forgings can be placed in two V block, through the end of the measuring instrument to measure the jitter value. Forgings planar parallel examination may be selected forging a face as a benchmark, with the help of a measuring instrument to measure the parallelism error between parallel surface.
