Precautions for controlling gravity casting machine system

Gravity casting machine is a kind of equipment that uses gravity to inject molten metal into the mold for casting. Gravity casting machine has the characteristics of simple process, low cost, good casting quality and strong adaptability. It is widely used in automobile manufacturing, aerospace, machinery manufacturing and other fields. 1. Inspection before equipment operation Electrical system inspection Check whether the power connection is firm and whether the wires are damaged or aged....

What are the requirements for surface hardness and wear resistance of gravity casting molds?

1. Hardness requirements Mold base hardness: The base hardness of gravity casting molds is generally required to be between HRC35-50. For small and simple molds, the hardness can be slightly lower, around HRC35-40. This is because lower hardness is conducive to mold processing and repair. For example, some gravity casting molds for producing small aluminum crafts can meet basic use requirements within this range, and are convenient for repairing when the mold is slightly damaged, such as repair...

Detailed explanation of the structural principle of hydraulic press

The driving system of hydraulic press mainly includes two types: pump direct drive and pump-accumulator drive. Pump direct drive: The pump of this driving system provides high-pressure working fluid to the hydraulic cylinder, the distribution valve is used to change the direction of fluid supply, and the overflow valve is used to adjust the limited pressure of the system and play an overflow role at the same time. This driving system has fewer links and simple structure. The pressure can...

Four post hydraulic press operates normally, why does hydraulic press cylinders not move?

Four post hydraulic press operates normally, but the main reasons for the cylinder not moving are as follows: 1. The resistance of the actuator moving parts is too large. Troubleshooting method: eliminate the stuck and stuck problems of the 50 ton hydraulic press actuator; improve the guiding and lubrication conditions of the moving parts. 2. The oil pressure at the oil inlet of the 20 ton hydraulic press is too low and does not reach the specified value. Troubleshooting method: Check the...

What is the current situation of the domestic hydraulic press industry?

(1) From the perspective of production capacity and market, the output of domestic machine hydraulic presses has increased significantly every year. In 2016, the sales of domestic hydraulic presses were about 10 billion yuan, and in 2017, it reached 13 billion yuan. By the first quarter of 2018, the annual orders of various hydraulic press industries had been basically saturated. Compared with developed countries, domestic hydraulic presses do not have advantages in output value and sales...

Future development direction and trend of hydraulic press

(1) Hydraulic presses equipped with automatic loading and unloading devices or automated hydraulic presses will become the future development direction of hydraulic presses. At present, due to labor costs and technical problems, most domestic enterprises use manual loading and unloading. However, some developed countries have basically popularized automated production lines in the 1960s and 1970s. In order to improve their corporate image and production efficiency, domestic enterprises are now...

Follow us to learn what is a hydraulic press

A hydraulic press (also known as an oil press) is a machine that uses a relatively small hydraulic piston to apply pressure to a liquid and transfers the pressure to another piston with a larger area, thereby generating a correspondingly large mechanical force. A hydraulic press is generally composed of three parts: a main piston, a power system, and a hydraulic control system. Hydraulic presses are divided into valve hydraulic presses, hydraulic control hydraulic presses, and engineering...
