How is the mechanical equipment used in the trimming die maintained?

Maintenance is a small amount of material along the shape or the contour of the inner mold, so as to improve the gloss and perpendicularity of the edge of a pressing process.How is the mechanical equipment used in the trimming die maintained?Maintenance processes usually have improved dimensional accuracy.15. Drilling is a pressing step in which material is turned to one side along the sides of the inner hole to create a flange.The opposite side of the anti-changsha nut punching rod is a kind of extrusion process which forms a short side along the side of the material around the contour curve.Depth deepening is the straight wool or engineering parts into hollow parts, or hollow parts to further change the shape and size of a stamping process.Deep space-time parts mainly through outside is located in the bottom of the punch and the material into the mold, 18, continuous depth of continuous depth on the material (coil), a suppression method, using the same pair of mould (continuous mode) deep stretch for many times, to form the necessary shapes and sizes, 19 thinning, thinning, depth is to change the shape and size of the hollow engineering parts, a kind of mean to make the wall thinning 1 kind of extrusion process, 20, the depth is flip tubular process outside the walls of a pull processing procedure;21. Temperature difference drawing depth by means of heating and shaoxing nut cooling, the temperature of the material in the deformed part is much higher than that in the deformed part, which is a depth step to increase the degree of deformation.Hydraulic throttling is a kind of extrusion process which USES the liquid in the rigid or zhejiang nut punching rod flexible container to replace the convex or mold and form the hollow part.Compression rib is a form of ups and downs.When local undulation occurs in the form of muscle, the corresponding undulation forming process is known as rib compression [1].
