CNC Hydraulic Sheet Metal Press Brake Bending & Shearing Machine

Sheet metal processing  sometimes also called Plate work processing. This word comes from the English words: plate metal. Generally, some metal sheets are stamped by hand or a mold to make it plastic variation and eventually form the desired shape and size, and it can further produce more complex parts through welding a small amount of machinery, such as the chimneys commonly used in homes, in furnaces, and car shells that are all sheet metal parts. Metal sheet punching is called sheet metal processing. Specifically, for example, chimneys, drums, fuel tanks, air ducts, elbows, heads, and gardens, funnels, etc., are manufactured using sheet metal. The main processes are shearing, bending, buttoning, bending, welding, and riveting. This needs certain geometric knowledge. Sheet metal parts are sheet hardware. That is parts that can be processed by means of stamping, bending, stretching, etc. A general definition is the parts with the same thickness during the processing. Corresponding...

With the rapid development of industry, the important role of sheet metal processing has become increasingly prominent. Laser processing is widely used in  sheet metal cutting . Welding and cladding and other fields due to its advantages of good flexibility, high precision, high speed, low thermal impact, ease of programming, and automation.  At present, laser surface modification technology is gradually being widely used as a new industry. China has trillions of yuan worth of equipment in service. Each year, due to the corrosion and wear of its key components, the losses caused by the suspension of production and retirement of the equipment account for 3% to 5% of the national economy's total output value. Laser surface modification technology plays an important role in the surface strengthening and manufacturing of vulnerable and consumable parts in industrial production. After several years of national scientific and technological breakthroughs in China, the technology has ...

The laser cutting technology is more cost-efficient than the traditional processing technology and the laser beams are all in the shape of points, therefore it has great flexibility in two-dimensional plane processing. In the laser cutting machine processing, only the cutting head moves, while the workpiece is stationary. There is no need to set up micro-connections, helping the laser in the cutting process is relatively simple. Its computer CAM system does not require the production of a single part machining process. It is only necessary to optimize the layout results and the cutting route, and then start the laser to process it. However, in the multi-functional machine, it is necessary to set the mold, preset the laser cutting route, and set the connection site, and then the next step can be taken. In comparison, the preparation time of the laser cutting process is greatly reduced compared with the laser cutting machine. In practical use, when the laminating machine is processing...

Sheet metal processing is an important process of sheet metal forming, and sheet metal processing factory is also a key technology for sheet metal technicians. It includes both the traditional cutting blanking, cutting processing, bending forming method and the process parameters, and includes a variety of stamping die structure and working principle of the process parameters.It also includes all kinds of equipment and operation method and includes the new punching technology and new technology. Application Shear plate blanking is the first working procedure in the process of sheet metal processing.The accuracy of cutting directly affects the quality behind the process of machining. CNC shearing machine ensures the blanking of the application of the differential size and the work of blanking diagonal. S stamping is an important part in sheet metal processing, and CNC punch can replace the processing power of three punch presses in the past. Prod...

The decorative and protective effects of sheet metal processing on the surface of the product are recognized by many industries.In the sheet metal processing industry, the surface treatment methods commonly used are electroplating, spraying and other surface treatment methods. 1. Electroplating is divided into galvanized (color zinc, white zinc, blue zinc, black zinc), nickel plating, chromium plating, etc.; It is mainly to form a protective layer on the surface of the material to protect and decorate. 2, spray paint and powder, is the materials after pretreatment, spray gun, air sprayed coating to the metal workpiece surface, coating on the workpiece surface coating. After drying, play a protective role; 3. Other surface treatment methods: anodizing, chromate, drawing, sandblasting, oxidation, etc.; Attention! 1. All electrochemical treatment shall be carried out in the state of the parts because the chemical solution in the process will be trapped in the gap between t...

A. Calculation formula of tonnage calculation for the non-diagonal cutting edge  power press punching machine : Formula: shearing strength (kn/mm2) = shock force (kn) of core circumference (mm) x plate thickness (mm) Convert to metric tons: KN divided by 9.81 The perimeter of the core - add up the sides of any shape Thickness of material - the thickness of the sheet that is perforated through the punch Shear strength of materials - physical properties of plates, determined by materials of plates, can be found in the material handbook. The shear strength of common materials is as follows: material shear strength (kn/mm2) aluminum 5052H32 0.1724 brass 0.2413 low carbon steel 0.3447 stainless steel 0.5171 For example: At 3.00mm thick carbon steel plate with punch, shape square, length 20.00 mm The core circumference = 80.00 mm material thickness = 3.00mm shear strength = 0.3447 kn/mm2 8.00 * 3.00 * 3.00 = 82.73 KN 82.73 KN present 9.81 = 8.43 metric tons B. Calculation formula o...

Today's hydraulic press brakes are offered in a broad range of capacities,following these six steps can make a significant difference in bending performance, wear and tear of system components, and the lifespan of the press brake. 1. Take a Look Around Verify that the hydraulic press brake is in clean condition. The table and die area should be free of mill scale, the punch and die alignment and inspect the tooling's condition. The actual position of the backgauge fingers should be checked and should match the readout value for the corresponding axes. Also verify the proper operation of all devices, including palm buttons, up button, e-stops, foot pedal control, and indication lights. 2. Take Precautions The press brake ram always should be supported before performing any maintenance work on machine hydraulics or the mechanical system. To do so, place the ram on two equal size wooden blocks or lower the ram, supported by the tooling.The electrical system should be locked ou...
