Press kit commonly used type of screw shaft axis consists of pressing and pressing sleeve in pressing screw shaft and from the ring components. Pressing screw is outside around a spiral bar that is a cylinder or cone of "Thread" hollow. Which the thread tip diameter called "thread diameter", i.e., the diameter of the thread bottom diameter of the outer cylinder or cone called "spiro bottom diameter" or "bottom circle diameter" old press, threaded around the circle opened the distance is called "pitch." When the press screw shaft and squeeze cage will be formed with a threaded channel in the form of old-fashioned press space price, known as virgin bore. Virgin bore structure and geometry will affect the squeezing process, such as a pressing machine production capacity, pressing bore pressure, squeezing effects. Pressing screw thread height determines the size of the screw shaft screw top and squeeze cage formed with a slit. If this gap size appropriate to work to ensure the pressing machine can be, if the gap is increased Nanyang Which is good old-fashioned press, will make virgin material "reflux" to increase or decrease the gap resulted in part through this gap when the virgin material overheating. Practice has proved that the most pressing machine suitable gap size of 1.25 to 1.5 mm. Which is good old-fashioned press Nanyang | press | Goodwin machinery provided by Nanyang City, Qi Feng Machinery Co., Ltd. Nanyang City, Qi Feng Machinery Co., Ltd.
