Sheet Metal Part Processing Process

1.Material: there are various ways of material, there are several important ways as follows

①. Hydraulic shearing machine: is the use of hydraulic shearing machine to cut strips of simple material, it is important for the mold shell drop molding ready for full processing, low cost, precision below 0.2, but only processing without holes without circular arc of the strip or block material surface layer.

②. Stamping machine tools: is the use of stamping machine tools in one or more steps in the plate after the parts to carry out the flat pieces of cold punching die forming various shapes of material parts, the advantage is to consume engineering construction time is short, high efficiency, high precision, low cost, can be used in mass production, but to program design die shell.

③. NC NC lathe under the material, NC under the material at the very beginning to write CNC lathe processing program flow, the use of CNC lathe programming cell phone software, will make the unfolding chart sister for NC number pull processing machining center can identify the program flow, let it according to this kind of program flow step by step in the flat plate cold punching die each structure die-like flat plate pieces, but its structure by the CNC tool structure to, low cost, precision in 0.15.

④. Laser laser undercutting, is the use of fiber optic line fiber laser cutting method, the structure of its flat plate mold fiber laser cutting out, the same as NC undercutting need to write the laser program process, it can undercut a variety of complex mold of flat pieces, the cost increases, the precision of 0.1.

⑤. CNC sawing machine: important to use under the aluminum, galvanized square steel, rectangular steel, round slippery bar such, low cost, low precision.

2. Planer: countersink, tapping, punching, opening holes

Countersink angle generally 120 ℃, for pulling rivets, 90 ℃ for countersunk head bolts, tapping the outer diameter of the external thread bottom hole.

3. reverse side: also called draw hole, flip hole, that is, in a smaller base hole drawn into a slightly larger hole, and then tapped, important with the plate thickness is relatively thin sheet metal processing, improve its tensile strength and imperial thread coil turns, to avoid slippery teeth, generally used for the plate thickness is relatively thin, its hole perimeter all normal shallow reverse side, the thickness of most no change, allow a thick and thin variation of 30-40% when you can get than all normal Reverse side of the high aspect ratio of 40-60% higher than the high aspect ratio, with squeeze thin 50%, can get a large reverse side of the high aspect ratio, when the plate thickness is very large, such as 2.0, 2.5 and other thin thickness, it can be immediately tapped.

4. punching machine tools: is the use of mold shell forming processing production process, general punching machine tools processing are automatic punching machine, arc, drop, punching convex package (abrupt point), punching tearing, pumping, forming and other processing methods, its processing must have the relative corresponding mold shell to carry out the operation process, such as automatic punching machine drop die, convex package die, tearing die, pumping die, forming die, etc., the operation process is important to note the location, specificity.

5. Press riveting: As far as our company is concerned, there are important press riveting nuts, screws, pine not unloading, etc., which are based on four-column hydraulic press riveting machine or stamping machine tools to carry out the operation process, riveting them to the sheet metal parts, which also have the way of up riveting, and need to pay attention to the specificity.

6. Sheet metal bending: Sheet metal bending is the process of bending 2D flat parts into 3D parts. Its processing must be carried out with a bending machine and a corresponding bending die. It also has a certain bending order for sheet metal parts, and its standard is to bend first for the next knife that does not cause interference, and to bend later for the one that will cause interference.

Sheet Metal Part Processing Applications

The processing steps for processing prefabricated components in sheet metal parts production plant are: initial product testing, product processing product development and product mass production and processing. In the process of product development, we should immediately communicate with the customer and get the evaluation of the relative processing before mass production and processing.

Laser perforation technology is the first laser cutting equipment to be put to practical use in laser generator raw material processing technology. Sheet metal parts production shop in the laser punching is generally used in the pulse laser, high energy density, time is short, can be processed 1μm small hole, especially in the available processing with a certain angle and the raw material is thin small hole, but also suitable for processing tensile strength compressive strength is higher or more brittle too soft raw materials on the parts of the deep small hole and micro small hole.

The laser generator can be used for the processing of holes in prefabricated components of small turbine burners, the actual effect of which can be carried out in a three-dimensional direction, and the number of more than a hundred can be guaranteed. The raw materials used for drilling include stainless steel sheets, rare metals such as nickel-chromium and HASTELLOY cobalt alloys. Laser punching technology is not susceptible to damage from the raw material's process properties and is relatively easy to automate and control.

Under the development trend of laser punching technicality, fiber optic line fiber laser cutting has completed the operation process of automation control, and the application in the sheet metal parts industry has changed the traditional processing method of sheet metal parts technicality, completed the operation process of nobody, further improved the production efficiency, carried out the whole process of fully automatic operation process, promoted the development trend of sheet metal parts is the development of social and economic development, and raised a level in the actual effect of opening holes, and the actual effect of processing is clear and remarkable.
