Operating procedures and work efficiency of industrial aluminum profile extrusion press machine plant line
Aluminum profile extrusion press machine plant line are mainly used for producing copper and copper alloy pipes, bars, profiles, and wire extrusion machines. According to its transmission mode, it can be divided into mechanical transmission mode and hydraulic transmission mode. Mechanical transmission extruders are prone to impact when the load changes. They are not sensitive to the adjustment of extrusion speed. Its overload protection capability is small and difficult to apply on a large scale. Generally used for small tonnage high-speed cold extrusion, but currently rarely used. The hydraulic transmission extruder runs smoothly, has good adaptability to overload, and the extrusion speed is easy to adjust. Suitable for extrusion of various pipes, rods, profiles, and wire products. At present, it has been widely used.
When pouring the aluminum extrusion machine, there is no relative sliding between the steel billet and the extrusion cylinder. The metal flow is concentrated near the mold hole and the deformation is relatively uniform. Reverse extrusion eccentricity is better than forward extrusion eccentricity. Low energy consumption, low residual pressure, and high production during extrusion. However, the operation of backward extrusion is more complex, and the gap time is longer than that of forward extrusion. The quality stability of the extruded products needs to be further improved, and the backward extrusion process needs to be further improved. Aluminum materials have the characteristics of strong controllability, flexible production, and convenient maintenance and transformation of molds.
The working efficiency of aluminum extrusion machines is closely related to their service life and the installation sequence of aluminum profile extrusion machines. The equipment foundation of the aluminum profile extrusion machine can not only bear the weight of the equipment itself and the weight of raw materials, but also withstand the dynamic load of the extrusion machine. Therefore, it is necessary to install the aluminum profile extruder according to the corresponding installation procedures. Excavate foundation pits according to the specifications of the equipment, while also excavating trenches for electrical circuits, water supply and drainage pipelines, and compressed air pipelines. Extruder bolt hole size, fixed foot hole wooden mold. The wood grain of the bottom hole should be trapezoidal or large conical. Once, irrigate the foundation and leave your toes behind. On the basis of straw bags, after 24 hours, twice a day, drinking water is hygienic. During cement-based curing, the ambient temperature should be above 5 ℃.
Operating procedures for industrial aluminum profile extrusion machines
1. Check whether the oil pressure system leaks oil and whether the air pressure is normal.
2. Check the conveyor belt, cooling bed, and storage table for any damage or scratches on the profiles.
3. Before stretching, the length of the aluminum profile should be confirmed, and then the stretching rate should be predetermined to determine the stretching length, which is the position of the main clamp movement.
4. Confirm the clamping method based on the shape of the aluminum extrusion machine. Large cross-section hollow profiles can be inserted with stretching pads, but try to ensure sufficient clamping area.
5. When the aluminum profile cools to below 50 ℃, it can be stretched.
6. When the profile has both bending and twisting, the twisting should be corrected first and then the bending should be pulled.
7. Perform a trial pull on one or two pieces to confirm whether the predetermined stretching rate and clamping method are suitable. Visually bend, twist, and check the plane clearance, flaring, and parallel opening of the profile. If not suitable, adjust the stretching rate appropriately.
8. When the normal stretching rate still cannot eliminate bending, twisting, or the geometric dimensions cannot be qualified, the operator should be notified to stop squeezing.
