Basic knowledge of sheet metal in Ningbo sheet metal processing

When CNC sheet metal processing, everyone will definitely use sheet metal materials, we seem to have the following common sense issues about sheet metal today:

1、Hot-dip galvanized sheet metal: SECC(N)(fingerprint resistant sheet metal), SECC(P), DX1, DX2, SECD(tensile sheet metal). Material strength:HRB50°±5°? Stretched plate:HRB32°~37°.

2、Cold-rolled steel plate: SPCC, SPCD (drawing plate), 08F, 20, 25, Q235-A, CRS. material strength:HRB50°±5°? Stretched plate:HRB32°~37°.

3、Aluminum alloy plate:AL,AL(1035),AL(6063),AL(5052),etc.

4、Stainless steel plate:SUS, SUS301(302, 303, 304), 2Cr13, 1Cr18Ni9Ti, etc.

5、Other common materials are: pure copper money (T1 processing, sheet metal processing in the sheet metal of the basic common sense problem T2), hot-rolled steel plate, spring steel sheet, hot-plated aluminum, zinc-aluminum alloy profiles, etc.

For the information about sheet metal parts processing, which has been covered in the previous, go into details today, for example, how to control the processing quality in sheet metal processing in the hardware sheet metal processing plant, that is also a more major level for sheet metal processing. For sheet metal bending, it is necessary to specify the milling cutter and cutter slot to be used for sheet metal bending according to the proportion of the drawing and the thickness of the material, to avoid the impact between the commodity and the CNC blade, which may cause deformation. In addition, the sequence of sheet metal bending is also very important, which is generally inside first and then outside, small first and then big, and unique first and then general. If the workpiece is to be bent to a dead edge, it should be bent to a flat die. In addition, the studs should be flush with the surface of the workpiece to prevent the workpiece from being damaged and unusable. The electric welding in professional sheet metal processing customization, generally there are hydrogen-argon arc welding, welding, electric arc welding and its carbon dioxide protection welding. When making welding, it is necessary to know the welding position. Medium Sheet Metal< How to implement the quality of sheet metal processing to Z good sheet metal processing, the surface processing is to be selected according to the actual situation. In the case of cold rolled sheet metal processing, the plating process is generally carried out first, followed by pickling and phosphating, and then spray painting. In the case of painting, there is a difference between manual production and automatic production. In addition, after the sheet metal is processed, it needs to be checked in appearance, including specifications and other aspects, and if there are any problems, it should be repaired or scrapped immediately, so that the processing quality can be guaranteed.
