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,...
The hydraulic press is a device that uses hydraulic drive technology for pressure processing and can be used to perform various forging and press forming operations. For example, the forging of steel, the formation of metal structural parts, plastic products and rubber products such as suppression. Hydraulic press is one of the earliest applications of hydraulic transmission. At present, hydraulic transmission has become the main transmission form of pressure processing machinery. In heavy...
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...
YH25-315 series hydraulic press is vertical structure four-column hydraulic press, which is composed of fuselage, main hydraulic cylinder, hydraulic power system and electrical system. Its hydraulic system consists of energy conversion devices (pumps, hydraulic cylinders), energy conditioning devices (various control valves), and energy transmission devices (oil tanks, fluid-filled tank pipes, etc.), with the help of electrical systems, to complete a variety of process actions. In order to...
1. Introduction The hot bending machine uses hot bending equipment and fixtures such as ovens and graphite molds. The glass is first heated to the softening point, and the 3D curved surface curvature of the glass is fixed by freely fitting mold forming or mold pressure forming, and then cooling and forming . This machine adopts programmable logic controller (PLC) control and man-machine interface control. The cruise mode can be set, and you can operate without interruption by pressing the...
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...
The hydraulic press is a device that uses hydraulic transmission technology for pressure processing; it can be used to complete various forging and press forming processes, such as forging of steel; forming of metal structural parts; restrictions on plastic products and rubber products. Hydraulic presses are the first to use hydraulic pressure. One of the transmission machinery; the current hydraulic transmission has become the primary transmission method of pressure processing machinery. In...
First, the system defects and hydraulic system have been greatly improved, and the double cylinder type has been changed to a single cylinder with a guide rod type. How to apply the advantages of the new hydraulic system (single cylinder) to the 400t twin-cylinder hydraulic press installed in 1980 by our factory. For many years, the first problem to be solved is how to connect the filling valve to the double cylinder. Connect and fix. After repeated research, we designed a four-way base block...
one. The high-frequency hydraulic press operator should know the general performance and structure of the hydraulic press. It is strictly forbidden to use the overload. Before use, you must carefully read the specific details in the text description of the high-frequency hydraulic press to ensure safe use. two. Before using the high-frequency plastic hydraulic press, add a suitable amount of lubricating oil to the mechanical activity of the machine, check whether the high-pressure pump,...
Key success factors for the marketing competition of reinforced bar bending machine From the perspective of the industry chain, there are many similarities in the theoretical system of reinforced bar bending machine marketing and consumer product marketing, but there are qualitative differences in the actual operation process. The difference between the consumption characteristics of steel bar bending machine and consumer products. Characteristics of the domestic consumer goods industry First,...
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...
There are many kinds of hydraulic presses. Common single-column hydraulic presses, four-column hydraulic presses, and frame-type hydraulic presses are used. Each type of hydraulic press has its own characteristics and has different uses. In order to have a better understanding of hydraulic presses, today's hydraulic press manufacturers The difference between the single-column hydraulic press and the four-column hydraulic press makes simple analysis. Hydraulic press manufacturers pointed out...
First, the valve leakage: Reason: 1. Strict closure 2. Combination of surface damage 3. Spool and stem clearance is too large, resulting in spool drooping or contact is not good 4. Poor sealing material or spool jam. Treatment: 1. Improve operation, reopen or shut down 2. Valve disassembled, valve core, seat sealing surface regrind 3. Adjust the valve stem and valve stem clearance or replace valve 4. Valve disassemble, eliminate jam 5. Replacement Or surfacing seals Second, the filler leakage:...
