1. Press in the course of work has a certain impact.
2. The press is passed through the spiral auxiliary energy, the plastic deformation of the metal when the slider and the work between the table by the force of the frame closed by the press to form a closed force system, and not rumored.
3. The stroke of the press slide is not fixed, the press itself is better than the forging hammer and has a lower ejector mechanism.
4. The screw of the press and the slider of the reciprocating movement are non-stevable, so the screw press is poorly tolerated.
5. Press the number of strokes per minute is less.
Due to the working characteristics of the press, its forging process and mold design has the following characteristics:
1. Press forging on a press, usually for the final finish of a single mold, with other equipment for blanking. In the case that eccentric load is not large, you can also arrange two mold bore. But the center distance of the mold bore should not exceed the radius of the screw pitch circle.
2. Because the stroke of the press is not fixed and the ejector is installed, it is more suitable for upsetting for closed forging, precision forging and long forging. For the extrusion and trimming processes, the limit travel device is to be taken on the mold (or on the equipment).
3. Due to the ejector device, the forging pitch can be reduced;
4. As the travel speed is slow, the metal in the mold chamber stays a long time and cool fast, so the ability to fill the mold chamber is Inferior than the hammer on the die for some. Die forging generally no more than three blows.
5. Due to the low speed, the mold can be combined structure, thus the mold manufacturing process, shorten the production cycle, and can save mold steel and reduce production costs.
Zhengzhou Hualong Machinery Manufacturing Co., Ltd. was established in 1980, focused on the press production R & D 37 years, the company's products have advanced and stable and efficient production, the production of the press has become more mature, in recent years by virtue of strong The R & D production capacity, and gradually replaced the foreign brands, has became an important force in R & D and production of press industry.
