JIATONG PRECISION SHEET METAL

  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 support can be made of a variety of metals, depending on certain fa...

  Engineers and designers must ensure that the CAD system they purchase is compatible with the current program. If not, they may start from scratch. The initial requirement is to determine the sheet metal compatibility in the CAD setup you plan to purchase. However, no single CAD system can meet all your design needs, which is the fact that all of us must accept. In addition, some of the most advanced CAD systems available today may not be compatible with your current tools. Now there are more available CAD modeling platforms with sheet metal design functions, which can be easily used to develop 3D models. In addition, there are various CAD systems that can convert solid models into sheet metal elements, and then supplement plane patterns from them.    CAD system with manufacturability function design will improve productivity and minimize waste of time. It is strongly recommended to use DFM function in sheet metal product design, because this system can ensure the operab...

  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.     Most scaffolds are functional, and their purpose is to connect and support objects. However, brackets can also be decorative: since brackets are usually visible (e.g. mounted on shelves above the eyes), they may have a decorative and gorgeous feel, ranging from complex machined decorative features to gold plating.

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; It should be avoided that the unfolding size of parts is equal to the outline size of raw materials: the shape of plates supplied in the market is not square. If the unfolding size is equal to or very close to the outline, there is no allowance for the whole square, and the product size after direct processing has errors, which will affect the installation and use. For non-sprayed plates with decorative surface requirements, the decorative surface and grain direction shall be considered in combination with the plate materials. For any purpose, the plate with decorative surface shall be used and the grain direction shall be required. For non-exposed parts, the processing process shall...

  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.     Sheet metal parts have no specific structural requirements, and are generally designed according to product needs. On the premise of meeting product functions, the designed structure should be easy to process, low-cost and beautiful. For example, the door of the electrical cabinet can be external or embedded, which should be selected according to the design needs. The design of the door will be different with different structures. The material thickness of the external door is generally thicker than that of the embedded...

The sheet metal process and the structural design of sheet metal parts are inseparable. It is necessary to closely combine the sheet metal process, improve the structural design level of sheet metal parts, and design the structural parts with processing technology, so as to reduce the production cost and improve the production efficiency. 1 Design of Bending Edge The shortest bending edge of sheet metal is affected by the V-shaped opening width of the bending lower die and the bending R angle. The limitation of the shortest bending edge should be properly considered in the design. Assuming that the width of the V-shaped opening of the die under bending is 12mm and the bending R angle is 0.5mm, the minimum short side of bending cannot exceed vi2 + R + 0.5 = 7mm. Designers should design according to the existing bending lower die specifications of the factory, so as to avoid many unnecessary molds customized by the factory, which greatly increases the processing and management cost of mo...

  The main ways to realize the   precision machining   of parts are: using high-precision machining machine tools to process high-precision parts; Use error compensation technology to improve the machining accuracy of parts. Mechanical processing mainly includes manual processing and numerical control processing. “Sheet metal is a comprehensive cold working process for sheet metal (usually less than 6mm), including shearing, punching / cutting / compounding, folding, welding, riveting, splicing and forming (such as automobile body) Etc. Its remarkable feature is that the thickness of the same part is consistent. The products processed by the sheet metal process are called   sheet metal parts . The way to distinguish whether a part is a sheet metal part or a machined part on a mechanical drawing is to see whether the thickness of the part is consistent. The thickness of sheet metal parts is consistent, while the thickness of machined parts is inconsistent.   ...
