7.1 The assembly process of the mold can be summarized as followsDie handle assembly, guide sleeve assembly, guide post assembly, mold base, lower mold assembly, upper mold assembly, trial mold7.2 The assembly has technical requirements(1) The closed height of the combined die should meet the design requirements;(2) After the mold handle is installed in the mold base, the perpendicularity error between its axis and the plane of the upper mold base within the full length range is not more than 0.05mm;(3) After the guide post and guide set are equipped, the axis should be perpendicular to the bottom surface of the lower mold base and the upper plane of the upper mold base, and the verticality error should meet the requirements of the table;(4) The upper plane of the upper mold base should be parallel to the lower plane of the lower mold base, and its parallelism should meet the requirements;(5) The fit clearance (or interference) of each pair of guide posts and guide sleeves installed in the mold base should meet the requirements;(6) When assembling the mold base, the mold base should move up and down along the guide column smoothly without jamming;(7) The fixed end surface of the assembled guide post should be kept at a distance of 1-2mm from the lower plane of the lower mold base. Choose a B-type guide sleeve. After assembly, the fixed end surface should be 1-2mm lower than the plane of the upper mold base;(8) The gap between the punch and the die should meet the design requirements, and the contour should be uniform along the entire edge;(9) The positioning device should ensure correct and reliable positioning, the unloading and jacking device should be flexible, and the correct discharge hole should be unobstructed to ensure that parts and waste are not stuck in the die;(10) The mold should be tested at the production site, and the punched product should meet the design requirements.7.3 Select stamping equipmentAccording to the total punching pressure F total = 97.7 (kN), the clamping height H = 245mm, the size of the punching table, etc., combined with the existing equipment, the J23-63 open-type double-column tilting press is selected. The main process parameters are as follows:
