aluminum profile extrusion press machine plant line has good adaptability
aluminum profile extrusion press machine plant line is mainly used to produce copper and copper alloy pipe, bar, profile and wire extruder. According to its transmission mode can be divided into mechanical transmission mode and hydraulic transmission mode. Mechanical extruders are vulnerable to impact when the load changes. They are not sensitive to adjustment of extrusion speed. Its overload protection capacity is small, difficult to large-scale application. Generally used for small tonnage high speed cold extrusion, but rarely used at present. Hydraulic extruder runs smoothly, has good adaptability to overloading, and is easy to adjust the extrusion speed. Suitable for all kinds of pipe, bar, profile, wire products extrusion. At present, it has been widely used.
When casting aluminum profile extrusion press machine plant line, there is no relative sliding between billet and extrusion cylinder. The metal flow is concentrated near the die hole and the deformation is uniform. Backward extrusion eccentricity is better than forward extrusion eccentricity. Extrusion has low energy consumption, low residual pressure and high yield. However, the operation of backward extrusion is more complicated, the clearance time is longer than that of forward extrusion, the quality stability of extruded products needs to be further improved, and the backward extrusion process needs to be further improved. Aluminum has the characteristics of strong controllability, flexible production, convenient maintenance and transformation of tools and molds.
The working efficiency of aluminum profile extrusion press machine plant line is closely related to the service life of the extruder and the installation sequence of aluminum profile extrusion press machine plant line. The equipment foundation of aluminum profile extrusion press machine plant line can not only bear the weight of the equipment itself and the weight of raw materials, but also can bear the dynamic load of the extruder. Therefore, the aluminum profile extrusion press machine plant line must be installed according to the corresponding installation procedures. Excavate the foundation pit according to the specifications of the equipment, and excavate the grooves of electrical lines, upstream and downstream water pipes and compressed air pipes at the same time. Extruder bolt hole size, fixed foot hole wood mold. Wood grain of bottom hole should be trapezoid or large conical. The first time, irrigate the foundation and leave the toes. On a straw bag basis, after 24 hours twice a day, drinking water is sanitary. During cement-based curing, the ambient temperature should be above 5℃.
