For hollow variable-section structural members, the conventional manufacturing process is to first form two halves of the sheet and then weld them into a whole, and hydroforming can integrally form a hollow structural member that varies along the cross-section of the member at one time. Compared to stamping and welding processes, hydroforming techniques and processes have the following major advantages: 1. Reduce quality and save materials. For typical parts such as automobile engine brackets...

Fault one: The hydraulic system of the hydraulic bending machine has no pressure 1. If the electromagnetic coil of the proportional relief valve is energized, whether the proportional solenoid voltage meets the requirements or not, for the above reason, please check the relevant electrical reasons. 2. Check if the cartridge valve is stuck or if the main spool is jammed and the damping orifice is blocked. If this is the reason, remove the relief valve and clean it and reinstall it. 3,...

A hydraulic press is a machine that uses liquid as a working medium to transfer energy to achieve various processes. In addition to forging forming, hydraulic presses can also be used for correction, press fitting, packing, briquetting and pressing. The hydraulic press includes a hydraulic press and a hydraulic press. A water-based liquid is used as a working medium, which is called a hydraulic press, and an oil as a working medium is called a hydraulic press. The specifications of hydraulic...

First, inspection and debugging (1) Before the oil pump test, first add clean mechanical oil or vegetable oil in the fuel tank, and press the handle up and down to see if the piston of the oil press rises. If the piston does not rise or the handle is not stressed when it is pressed, check the valves in the tank and remove the air from the line. (2) Carry out the whole machine withstand voltage test, the pressure used in the test is 1.25 times of the working pressure, check that the piston...

01 Use a sharp blade to reduce the cutting force of a CNC milling machine. Clip blades are divided into coated and uncoated blades. Uncoated blades are usually sharper than coated blades because the blade must be passivated (ER) if it is to be coated. Because the sharp edge will affect the coating in the edge of the bond strength. 02 With a constant cut depth, the use of a small nose radius can undoubtedly reduce cutting forces, especially radial cutting forces, which are the main cause of...
