The working principle of hydraulic press is based on Pascal's law. Pascal's law states that the pressure on a sealed liquid can be transmitted in all directions with a constant magnitude. In hydraulic presses, this principle is used to transmit and amplify force through liquid. Specifically, hydraulic presses use hydrostatic pressure to process products such as metal, plastic, rubber, wood, and powder. It mainly consists of hydraulic pump, integrated plug-in valve block, hydraulic cylinder and other parts. Hydraulic pumps convert mechanical energy into hydraulic pressure energy, which is then distributed to the upper or lower chambers of hydraulic cylinders through valves. The piston inside the hydraulic cylinder moves under the push of high-pressure liquid, thereby achieving the transmission and amplification of force. The application of hydraulic presses is very extensive, commonly used in various processes such as forging, stamping, cold extrusion, straightening, bending, flanging, thin plate deep drawing, powder metallurgy, and press fitting. For example, in the forging and stamping processes, hydraulic presses can provide a larger total pressure, forging hydraulic presses use molds for forging, while free forging hydraulic presses do not require molds О About us
Shanghai Tongri power science and Technology Co., Ltd. is a company specializing in manufacturing CNC machine tools and paper casing equipment. In 1990, Taiwan's Hao Li factory began to jointly produce reels. In 1992, we began to develop semi-automatic tapered paper casing and a set of spiral paper casing equipment on the basis of advanced processing technology, Processing technology, excellent product quality, excellent service, products are sold all over the country.
In 2006, after Germany, South Korea and other countries introduced advanced technology, Qzd-68 automatic production line has been developed and implemented, which is used to produce paper cone-shaped textiles. System. The new technology realizes the production of low-cost labor, low energy consumption, high efficiency and high-quality tapered paper casing.
In 2012, we contacted many domestic customers, and our equipment has also been improved and modernized by international advanced experience. Recently, a new fully automated trz-2017 paper tapered casing production line has been launched, and the use of raw materials has been improved and approved by customers.
We have more than 30 years of experience in the production of machinery and equipment.
We have more than 30 years of experience in the production of paper covers and hairpins.
