Embodiment Construction

[0050] According to the characteristics of large production batches of blanking parts, high requirements for material utilization, and high requirements for shape accuracy of blanking parts, it can be seen from the "Stamping Die Practical Manual" that the edge value of processing stainless steel 304 is ≥ 2.8mm. If the layout overlap value does not meet the requirements, it will easily lead to material deformation and damage, and the problem of punch processing and manufacturing should be considered in the design.

[0051] Due to the small size of the punch, the stripper has the function of protecting the punch and guiding at the same time. In order to facilitate replacement, the punch is designed as an insert structure, and the material is cold work die steel (C r 12MoV), fixed by screws and positioned by positioning pins. The width of the plate is 300mm, the thickness is 0.5mm, and the material is 304 stainless steel. The chamfer produced by stamping is required to be as sma...

Abstract

The invention discloses a male and female inlaid mould, mould and system for a sol-gel (SG) abrasive material microreplication forming hole. According to the male and female inlaid mould, mould and system for the SG abrasive material microreplication forming hole, distribution conditions of male mould units are adjusted according to the sizes of workpieces, the size of a related cutting-building side value and a manufacturing mode of a related mould, and the number of the male mould units is determined according to the size of blanking force and the size of the cutting-building side value; and a automatically-feeding system designed according to characteristics of a stepper motor is matched with a layout mode mentioned in the invention, and a machining system capable of continuously machining and blanking can be achieved through mutual matching.

Description

technical field [0001] The invention relates to the field of pressure processing, in particular to convex and concave molds, molds and systems required for thin plate dense small holes and high shape precision. Background technique [0002] In recent years, a new type of SG abrasive grinding wheel has been introduced in the international tool market. Its grinding performance is between the superhard cubic boron nitride (CBN) grinding wheel and ordinary corundum grinding wheel. Much higher than the corundum grinding wheel, the price is moderate, but it does not have high requirements for grinding machines like the CBN grinding wheel, so it has been favored and welcomed by the majority of users, and its use area is expanding day by day. It is made of corundum crystals with sub-micron grains, synthesized by Sol-Gel (Sol-Gel) process and sintered. Because the abrasive grains have a microcrystalline structure and have many crystallographic planes, they are During sharpening and ...
