Brackets can be manufactured in various ways, such as casting or CNC machining. However, the best way to make simple supports is sheet metal. One of the most common sheet metal processes is bending, in which a machine called a brake is used to bend the sheet metal to a maximum angle of 120 °. This is probably the most important process when manufacturing sheet metal supports, because almost all supports contain at least one bend. Other sheet metal processes must also be used. Before any bending, the sheet metal must be cut to a certain size by using a machine such as a laser cutter or a plasma cutter. You can use a punch to punch holes in the bracket (for screws), and you may need to weld to add gusset plates or other features. In addition to the above sheet metal process, CNC machining can also be used to add more complex features to the support, especially for customized design of non-standard parts.
The L-bracket is usually designed for a 90 ° angle, but the manufacturer can create different angles (up to 120 °) according to the instructions.
One of the simplest and most cost-effective methods of manufacturing brackets, especially simple brackets such as corner brackets, is sheet metal manufacturing. The bracket is usually composed of two or more planes connected along an edge. The easiest way to make this object is usually to bend a flat object (i.e. a metal plate) at two or more positions: the simplest example is to add a flat rectangle bent at 90 ° to form a straight contour, and turn it into a bracket with an L-shaped contour.
(1) In order to ensure the material utilization rate and the minimum number of die changes in bending, the thickness specifications of plates on the same structure shall not exceed three at most. For structures with high strength requirements, the method of pressing reinforcement on thin plates can be adopted;
1. In the principle of convenient installation, the hanging beam is adopted, which is convenient and flexible for installation and movement.
Sheet metal generally deforms some metal sheets by hand or die stamping to form the desired shape and size, and can further form more complex parts through welding or a small amount of mechanical processing, such as chimneys, iron barrels, oil tanks, ventilation pipes, funnel shapes, etc. commonly used in families, and also such as electrical cabinets, shells of various special equipment, computer cases, automobile shells, etc. are sheet metal parts.
With the continuous improvement of people’s living standards, sheet metal chassis has been widely used in all aspects of our life, but at the same time, because the role of sheet metal chassis is very important, the processing of sheet metal chassis is relatively strict. We can only fully understand the various processes involved and follow the relevant requirements, so as to better ensure that the processing quality of sheet metal chassis can meet the requirements.
The sheet metal part is a curved protective cover, which is made of aluminum magnesium alloy, with a thickness of 1m. The protective cover is designed to be 118m long, 160m wide, 60m deep, 20m flange along the circumference, and the end face of the protective cover is a mixed curved surface.
On the surface of some sheet metal chassis cabinets with poor quality, there are often sundries on the base, serious color difference, falling off of coating layer, paint flow, powder deposition and other conditions, which are actually caused by some mistakes in the sheet metal processing process of sheet metal chassis cabinets;
Sheet metal processing is an important process for the forming of sheet metal products. The scope of sheet metal is relatively large, including traditional cutting and blanking, blanking, bending and forming methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operation methods, as well as new stamping technology and new processes.
Cyanide zinc plating Because (CN) is highly toxic, environmental protection has put forward strict restrictions on the use of cyanide in galvanizing, constantly promoting the development of cyanide reduction and cyanide replacement electroplating solution system, requiring the use of low cyanide (micro cyanide) electroplating solution. After electroplating with this process, the product quality is good, especially the color plating, and the color remains good after passivation.
With the development of social economy and industrial progress, sheet metal parts are more and more widely used in our daily production and life. Automobiles, machine tools, and various household appliances all use a variety of sheet metal parts. Therefore, how to make sheet metal parts with good quality and beautiful appearance is particularly important.
