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 ...

1. Background As an important tool for the improvement of enterprise management level and information integration, ERP is a new management means combined with IT technology and management. It has been accepted and applied by more and more Chinese enterprises.

As a hydraulic device, the interior of the  Hydraulic press brake bending machine  is equipped with the corresponding hydraulic oil pump, which has many types, so what kind of oil pump is often applied in a hydraulic bending machine among gear pump, screw pump, vane pump, plunger pump and so on? The gear pump used in a hydraulic bending machine is simple in structure, good in technology, small in volume, light in weight, easy to maintain and long service life. However, the working pressure is low, while the flow pulsation and pressure pulsation are large, so the volumetric efficiency of hydraulic bending machine will obviously decrease under high pressure without end compensation. The screw pump used in a hydraulic bending machine is also a kind of gear pump, which is simple in structure and light in weight. Flow and pressure pulsations are small, conveying even, without turbulence and stirring, and rarely bubbles produced. The work is reliable with small noise and so on,...

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...

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...
