  • Mold technology trend of CNC bending machine


    The bending machine mold manufacturing industry is also one of the industries with a large amount of CNC bending machine molds. In automobiles, high-speed trains, general machinery manufacturing, and the wood processing industry, which has gradually expanded its usage in recent years, have become the main users of the CNC bending machine mold industry.  The aerospace industry is a traditional and important application field of CNC bending machine molds. In this industry, CNC bending machine mol

  • How to adjust the bending force of the press brake ?


    Before using the bending machine to bend the material, you need to adjust its various data, including the bending force, the distance of the back gauge, the upper limit of the slider, the speed of the slider, and the adjustment of the upper and lower mold gaps, etc., to make it reach Actual operation requirements. How to adjust these parameters? Regarding the adjustment of the bending force of the press brake, it is mainly to calculate the kN value of the bending force of the sheet metal acco

  • What is a hydraulic CNC press brake


    In recent years, the hydraulic CNC bending machine industry has experienced high-speed and low-speed development. The low-end products of this industry are gradually far away from users' vision. Low-price competition and imitation have become obstacles in the development of the industry. Now with continuous development, More and more bending machine companies feel that to develop, they must improve the technical content of their products. It is a long-term development strategy to study more

  • The development trend of CNC Press Brake system


    First of all, let's understand the basic concepts and definitions of bending machines. The bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a working table and a clamping plate. The working table is placed on the bracket. The working table is composed of a base and a pressing plate. The base passes through a hinge and a clamping plate. Connected, the base is composed of a seat shell, a coil and a cover plate, the coil is placed in a depression

  • Blade replacement techniques for guillotine shears


    The blade sharpening and replacement skills of the guillotine shears, the blades must be sharpened regularly. If sharpening is not performed for a long time, it seems to be trouble-free, but in fact it will cause a lot of waste. If the blade is cut blunt and continues to cut, the outer grain structure of the blade will be destroyed due to excessive pressure, which will damage the equipment and fail to obtain good shear quality. After the blade is sharpened, the damaged crystalline outer layer is

  • CNC press brake bending angle


    CNC press brake is currently the most common type of bending machine. Its function is to be able to quickly bend various metal materials as required. Then how should we use CNC press brake to perform various bending operations at different angles Woolen cloth? The upper and lower 90-degree molds can be uniformly used for 90 degrees or more, and the V-shaped upper and lower molds can be used for less than 90 degrees. Slowly adjust the angle of adjustment in one step. For angles greater than 90 d

  • Commonly used materials for CNC press brakemolds


    CNC press brake molds are widely used in the sheet metal processing industry, and are commonly used tools for sheet metal processing by bending machines. Bending molds can be divided into two categories, one is the upper mold (punch mold) and its accessories, and the other is the lower mold (concave mold) and its accessories. The mold assembly includes mold fixtures, molds, mold handles, mold heads, etc. The lower modules include lower molds, lower mold holders, mold bases, mold clamps, etc. T

  • Daily maintenance of bending machine


    1. Daily maintenance and maintenance before and after shifts 1. Pre-shift maintenance: (1) Lubricate the bending machine according to the lubrication label of the machine. (2) Check whether the limit switch is sensitive and in good condition. Check whether the various mechanisms and operating parts of the safety protection device fasteners are intact. 2. After-shift maintenance: (1) Cut off all power supplies. The parts and tools are returned to their original positions. Sweep and clean the

  • The problem of hydraulic oil pollution of CNC bending machine


    Heavy pollution of the bending machine oil will immediately jeopardize the characteristics of the hydraulic transmission system. What's more terrifying is that it will cause frequent failures of the hydraulic system and reduce the service life of the hydraulic bending mechanism. The specific reason for this risk is the particulate matter in the dust. As far as hydraulic components are concerned, the liquid particulate matter entering the component will promote the damage of the component dra

  • Cut a good workpiece with a laser cutting machine


    Since the laser power density has a great influence on the cutting speed, the choice of lens focal length is an important issue. After the laser beam is focused, the spot size is proportional to the focal length of the lens. After the beam is focused by a short focal length lens, the spot size is smaller, and the power density at the focal point is higher, which is beneficial for material cutting; but its disadvantage is that the focal depth is short and the adjustment margin is small. Generally

  • How to repair the cylinder of CNC bending machine


    The hydraulic cylinder of the hydraulic bending machine is mainly a hydraulic actuator that converts hydraulic energy into mechanical energy, and then performs linear or reciprocating motion. Cylinders are the main components of hydraulic cylinders, single pillars for mines, hydraulic supports, gun barrels and other products. The quality of their processing directly affects the life and reliability of the entire product. The cylinder barrel has high processing requirements, and its inner surface

  • Maintenance of hydraulic parts of CNC bending machine


    Regular maintenance should be performed on the relevant hydraulic components of the hydraulic bending machine 1. After using the newly purchased hydraulic bending machine for one month, check whether there is any deformation in the bends of the oil pipes. If there is any abnormality, they should be replaced. After two months of use, all fittings should be tightened. When doing this work It should be shut down and the system has no pressure. 2. The hydraulic bending machine cleans the hydrauli

  • How to achieve synchronization of electro-hydraulic CNC double-machine linkage bending machine


    Features of electro-hydraulic synchronous CNC bending machine: 1. The electro-hydraulic servo system is used to control the two-cylinder synchronization, and the high-precision grating ruler is used to form a fully closed-loop control. The synchronization control has high precision, and the bending precision and repeat positioning precision reach a very high level. 2. The CNC cylinder deflection automatic compensation system overcomes the influence of the deformation of the slider during the
