Embodiment Construction

[0010] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0011] When processing metal products, the traditional process is to put ordinary high-density wooden backing boards on the bottom, which belong to cardboard, and have insufficient support; on the top, cover aluminum sheets, with large gaps and no support. During the processing of metal products, the upper and lower metal burrs are easy to roll onto the surface.

[0012] However, in the present application, a cold stamping plate 2 is covered above the metal plate 1 to be processed, and a phenolic backing plate 3 is placed under the metal plate, and the hardness of the cold stamping plate 2 and the phenolic backing plate 3 is 90±5HD , a thickness of 1.5 mm. see figure 1 As shown, the present application uses a cold stamping plate 2 with a hardness of 90±5HD and a thickness of 1.5 mm and a phenolic bac...

Abstract

The invention discloses a method for improving metal plate processing burrs. A cold stamping plate covers the upper part of a metal plate to be processed, a phenolic aldehyde base plate is arranged onthe lower part of the metal plate in a supporting mode, the hardness of the cold stamping plate and the phenolic aldehyde base plate is 90+/-5HD, and the thickness is 1.5millimeters. According to themethod for improving the metal plate processing burrs, enough supporting force and thickness can be provided for the metal plate to be processed, zero clearance between a cover plate, the base plateand the metal plate is kept in the cutting process, and the phenomena such as level cutting and no burr are ensured.

Description

technical field [0001] The invention relates to the technical field of metal plate processing, more specifically, a method for improving metal plate processing burrs. Background technique [0002] At present, the automotive lighting industry has high requirements for heat dissipation. Usually, the design requires aluminum substrates / copper substrates as carrier boards for wiring. This type of metal board is difficult to drill and form in the PCB field. It is harder than conventional FR-4 boards in the PCB field. Conventional Tool production is easy to break the knife and burst holes. [0003] The traditional drilling method is as follows: place an ordinary high-density wooden backing plate (hardness 72±5HD, thickness 2.5MM) under the metal plate, and cover it with an aluminum sheet (thickness 0.15MM). The defect of this drilling method is: the high-density wooden backing plate of the pad below cannot be drilled through, and the high-density wooden backing plate and the alum...
