Recently, 6 machinery industry (JB/T) standards that our company was deeply involved in drafting were officially implemented, covering the four core areas of powder product hydraulic presses, servo interior parts hydraulic presses, CNC bending machine hydraulic systems, green design and green factories, marking that our company's technical strength and industry influence in the field of forging machinery standardization have once again been authoritatively recognized.   Among the standards implemented this time, JB/T 14832.1-2025 'Powder Product Hydraulic Press Part 1: Type and Basic Parameters', JB/T 14831.2-2025 'Servo Interior Parts Hydraulic Press Part 2: Technical Specifications', **JB/T 14831.3-2025 'Servo Interior Parts Hydraulic Press Part 3: Accuracy' and JB/T 14834-2025 'Technical Specification for CNC Bending Machine Hydraulic System' has officially entered into force on November 1, 2025. The above standards respectively regulate the model classification, technical requirements, accuracy inspection and system performance of high-end equipment such as powder metallurgy, automotive interiors, and sheet metal bending, providing a unified yardstick for industry product development, quality control, and market access.

The working speed of the hydraulic press is significantly slower than the return speed. This is not because it is technically impossible to achieve high speed, but because it is an active design trade-off based on power balance and molding process requirements. The core logic revolves around the inherent constraints of the hydraulic system 'pressure-flow-power' and is combined with the core demands of its industry application scenarios. The following is a detailed analysis from the four dimensions of principle, difference comparison, design consideration and application adaptation: 1. Core principle: 'Power Balance Law' of the hydraulic system The operating speed of the hydraulic machine is directly determined by the flow rate of the hydraulic oil (the greater the flow rate, the faster the actuator is pushed), and the core constraint of the system comes from the power limit of the hydraulic pump. The relationship can be expressed intuitively through the formula: Pump power (P) = Working pressure (p) × Flow (Q) (Note: The formula is a simplified model, the actual system efficiency needs to be considered, but the core logic is the same) The rated power of the hydraulic pump is a fixed value (determined by the motor power), so 'pressure

The return spring of the reversing valve of the hydraulic press not only has insufficient elasticity, but also has a skew phenomenon, causing the spool of the reversing valve to fail to return to its original position after a power outage. Therefore, the opening of the slide valve is too small, which throttles the oil passing through the reversing valve. The initial movement of the hydraulic cylinder is slow. When the temperature is low, the viscosity of the hydraulic oil is relatively high and the mobility is poor, resulting in the slow movement of the hydraulic cylinder. If the outside temperature is really too low, you can use a heater or corresponding insulation measures to increase the oil temperature at startup. The contamination of the oil should be checked; check whether dirt or colloid deposits are blocking the valve core or valve hole, and check the wear of the valve body. The throttling resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. The control pressure of the hydraulic system of the hydraulic press is too low. The piston rod of the hydraulic press is stuck with the cylinder or the hydraulic cylinder is blocked. The way to cover it is to promptly replace the hydraulic oil with better viscosity and temperature resistance. If the outside temperature

Hazards of excessive temperature of servo hydraulic press 1. The temperature of the servo hydraulic press itself is too high, which reduces the viscosity of the oil and the leakage increase, and the efficiency of the system and the capacity base of the pump will be reduced. The oil film of moving parts such as slide valves will become thinner and produces greater friction resistance, resulting in increased wear and affects the inability to operate the machine. 2. The temperature of the equipment is too high, causing it to deform itself. Different moving parts in the hydraulic components have different degrees of thermal expansion, which will cause jamming due to the small gap between them at the same time, thus reducing the working efficiency of the servo hydraulic press. 3. Excessive temperature causes the service life of hydraulic oil to be greatly reduced, blocking the gap between the small holes, causing the pressure valve to not work normally. 4. Excessive temperature rise causes the rubber seal to deform, accelerate the aging degree, and cause leakage. 5. The excessive temperature reduces the air separation pressure of the oil, resulting in a decrease in the working performance of the hydraulic system. Therefore, we must follow the different load requirements of the servo hydraulic press and enter it

Thanksgiving comes, and we open a new chapter together - Our company debuts at the first Shanxi (Dingxiang) Flange Forging Industry Expo in July, and the forging industry is in full swing. The grand opening of the first Shanxi (Dingxiang) Flange Forging Industry Expo not only sets up a new platform for exchanges and cooperation for the industry, but also gives us the honor to gather at the booth with the leaders of the Shanxi Provincial Department of Commerce, the Dingxiang County People's Government and the Hubei Forging Association, draw strength to forge ahead through careful guidance and anchor the development direction in in-depth exchanges. This trust and affirmation is not only a recognition of our deep cultivation and forging of strength in the field, but also an expectation for us to take root in Shanxi and serve regional industrial upgrading. As active participants in the first expo, we are well aware of the milestone significance of this grand event - it is not only a concentrated display of the industrial heritage of Dingxiang' 'China's Forging Hometown' but also an important signal for Shanxi's forging industry to move towards high-quality development. From displaying technical achievements at the booth to the same as the industry

The damage to the hydraulic valve parts during daily production and use of hydraulic presses is usually caused by the following reasons: 1. Deformation of physical structures due to long-term fatigue and overload. When the stress during work and external load stress during use exceed the yield strength of the part material, physical deformation of the external structure occurs, especially the bending deformation of the valve core of the overflow valve and the spring deformation, the reciprocating operation is inflexible, resulting in unstable system pressure or slow state transition process. 2. The valve core and valve body are seriously worn, and the gap is too large. The valve core and valve body (shelves), etc. are constantly friction during movement and use, causing changes in the size, shape and surface quality of the parts to change, and the quality is reduced and the effect is ineffective. The solenoid reversing valve core is worn and deformed, causing the valve to leak internally, resulting in reduced efficiency or unstable pressure, causing the system to not work normally. 3. The oil is not clean and causes the hairpin to wear, which will cause the hydraulic valve parts to not work normally, and may even cause hydraulic pressure.
