Screw press refers to the general name of pressure machinery that generates pressure by rotating more than one set of outer bolts and inner bolts in the frame. The screw of the electric screw press is a main pressure-bearing device. It has many types of forces, such as torsion, tensile stress, compressive stress, bending moment and various stress combinations, which are very complicated. Let’s take a look together:

The screw manufacturing, especially the screw of the clutch-type electric screw press, not only uses good nickel-chromium alloy steel, but also requires high heat treatment, screw thread, and transition surface processing, and its material and processing costs are expensive. Reasonable design of screw is of great significance to improve screw quality, service life and economy.

The screw of the electric screw press is an axisymmetric part, which is connected with the friction plate through the upper spline. The central round table of the screw transmits the forging force to the machine body through the thrust bearing. The lower part is threaded. The screw rotates during operation without axial movement. , Drive the slider to complete forging by pressing down the nut. When the clutch type electric screw press works, the screw converts the energy of the flywheel rotation into the linear motion energy of the slider, and then the slider completes the forging. Therefore, the screw is an important part of the electric screw press.

When the press is about to hit the workpiece downward, the clutch is combined and the flywheel drives the screw to rotate, thereby generating torque at the spline on the top of the screw, and the energy transmission is realized by the work of the torque.

The round table in the middle of the screw and the arc transition part of the upper and lower roots of the round table are one of the parts where the force of the screw is more complicated, and it is also one of the parts where the screw is often damaged. In this part, the screw is fixed on the fuselage through upper and lower thrust bearings and upper and lower thrust bearing trays. When the press is working, the striking force is transmitted to the fuselage through the upper thrust bearing.

Our company Shandong Zhengxiang Industrial and Mining Equipment produces electric screw press nuts. The main material of copper nuts for screw presses is high-strength brass. The chemical formula of high-strength brass is ZCuZn25Al6Fe3Mn3. The copper content is about 65% and the zinc content is about 65%. 24%. Aluminum can improve the strength, hardness and corrosion resistance of brass.

High-strength brass has good plasticity and can withstand hot and cold processing, but it is prone to medium temperature brittleness during hot processing such as forging. The specific temperature range varies with the Zn content, generally between 200 and 700 ℃. Therefore, the temperature during thermal processing should be higher than 700°C.

The raw materials used in the inlaid copper nuts produced by our company are produced by major domestic factories. All the raw materials for inlaid nuts comply with environmental protection requirements. Each copper nut is tested and passed the production process before being offline. The knurled size and shape of the inlaid nut can be customized according to the actual design requirements, and effective technical support is provided at the same time as the supply. Welcome to map for processing and production customization.
