The metal plate processing comprises the steps of: providing a metal blank; pressing the metal blank into a metal plate blank (300) having a plurality of pits / grooves (31) on one side of the metal plate semi-finished product (300) (32); pressing the material at the partition wall (32) toward the opening of the pits / grooves (31) until the phase of the pits / trenches (32) (200) having a plurality of small cavities so as to form a material having a plurality of small cavities so as to form a plurality of small cavities (200) adjacent to said pits / trenches (31) The Compared with the prior art, the present invention has the advantages of simple manufacturing process and low cost, Sheet Metal Fabrication and the hollow metal plate is made into a single structure, which saves material, has strong structure, high strength and wide application field.
Metal plate processing production
1. This is mainly due to the strength of the aluminum plate at the bend is not affected, aluminum plate color consistent;
2. Single-layer aluminum fixed stiffener, you can use the method of welding bolts, but in the welding parts of the positive are not allowed to appear traces of welding, Sheet Metal Fabrication but can not occur deformation, fade and so on, and should be welded firmly;
3. Single-layer aluminum fixed ears should meet the design requirements, fixed ear can be welded, riveting, stamping molding;
4. The corner of the opening part of the component that is not welded molding must be sealed with silicon sapphire seal.
Metal plate processing has three requirements, the primary problem is the outer layer of 0.5mm aluminum plate is absolutely not allowed to be bruised, and to ensure retention of 0.3mm polyethylene plastic, followed by the application of silicone sealant seal, Sheet Metal Fabrication to ensure that water can not leak Into the polyethylene plastic inside. Finally, in the process of preventing water leaching wet sheet, to ensure quality. This section shall, in addition to the four requirements for honeycomb aluminum, Sheet Metal Fabrication be processed in accordance with the requirements of the material supplier.
The self-made teaching aids made of metal as the main material are based on the scraps of social life. The use of trim materials before the need for self-made teaching aids. Sheet Metal Fabrication The following describes the metal plate processing skills.
First, the metal plate leveling
The leveling of the metal plate should be placed on the flat steel plane, with 30mm × 40mm × 400mm wood gently tapping the surface, the metal plate can be flat. Must not use the hammer in the stone on the knock on the whole, otherwise it will make the percussion parts thinner, more knock on the more uneven.
Second, the bending of metal plate
When the metal plate is bent to a length of 100 mm or more, Sheet Metal Fabrication a part of the metal plate may be placed on the section steel, and the bent portion may be left, and then the left and right portions of the sheet to be bent can be pressed with two pieces of wood.
Third, the metal plate cutting
Cut a little thinner tin, galvanized sheet, the general use of scissors with scissors or scissors with the general scissors on it. If you encounter 1mm or more than 1mm iron plate on the fixed, here are two cutting methods:
(1) by force cutting method: first than the scissors handle slightly thick iron tube set in the relatively straight handle on the scissors, and then the other scissors on the board, Sheet Metal Fabrication in order to make the scissors easy to operate, it is best to put scissors handle Of the place in advance to dig a pit, the scissors handle into the positioning.
Operation, the first iron into the knife-edge, and then force the pressure set in the scissors handle on the casing, because the casing to extend the force of the scissors arm, so very effort. Cut iron plate, as long as a little hard, iron plate to cut off. This method is limited to cutting 1-1.5mm thick iron plate.
(2) fixed shovel cut method: first cut the iron plate on the vise, the cutting mouth to align with the jaws, and then use a flat steel shovel from one edge of the iron to the other edge a little bit with a hammer Hit the steel shovel, so that you can cut the iron plate.
Fourth, the metal plate roll
The thin iron plate processed into a tin tube, first of all in accordance with the thickness of the iron pipe, length, cut a good metal, cut out the width of the metal to more than 1mm overlap part. Sheet Metal Fabrication Cut after a small angle on the inside of a triangle, and then with a tube of the general thickness of the metal rod pressure on the metal. And then hit the metal rod with a hammer, the metal knock out a groove, and then use the wooden side of the edge of the iron gently tapping together, out of metal rods, solder with a good seam.
Five, metal plate bite
The bite of the metal plate is to fold the edges of the two plates (or both sides of a sheet) and press against each other. This method of connection is called bite and is suitable for larger connections. There are many ways to bite. The most common method of bite is the slit single button, leaving a margin equal to the width of the bite, and the margin on the other sheet must be twice the width of the bite.
Metal plate processing, the sheet to draw the buckle line should be placed on the edge of the angle, with a wooden hammer will be bent down part of the 90 degree angle, and then flip up the sheet, and then bend the edge Inward buckle, do not buckle, to leave the appropriate gap. Use the same method to bend the edge of another piece of sheet metal, and then two pieces of sheet metal buckle each other, hammering bite, and then buckle the edge of the concave
