Does the aluminum profile extrusion press machine plant line have accessories and what should be confirmed before stretching?

Issue Time:2022/07/08
The aluminum profile extrusion press machine plant line is one of the extrusion machines, and it is also a website product and keyword. Therefore, it is necessary to pay attention to the learning requirements, and it is necessary to achieve a comprehensive level. Therefore, based on the above specific learning requirements, the following will lead you to learn and master the relevant knowledge of aluminum profile extrusion press machine plant lines, so that you can gain some from it, rather than nothing.

    1. Is the processing method of the aluminum extrusion press of the aluminum forming equipment a plastic processing method? Also, is there any accessories for this kind of extruder?

    The processing of aluminum extrusion press, from a professional point of view, is to apply external force to the metal blank in the extrusion cylinder to make it flow out from a specific die hole, and then, to obtain the product with the required cross-sectional shape and size . Therefore, from its definition, its processing method is a plastic processing method. And this kind of extruder must have accessories. Generally speaking, there are thimbles, scale plates and skateboards.

    2. In the aluminum profile extrusion press machine plant line, the volume method and the practical gravimetric method are used to calculate the parameters of the aluminum rod. Are the calculation formulas the same?

    In the aluminum profile extrusion press machine plant line, the calculation of the parameters of the aluminum bar includes the volume method and the practical weight method, and their corresponding calculation formulas are different. In the volume method, the calculation formula of the extruded length of the aluminum rod is (aluminum rod length / upsetting coefficient - overpressure thickness) * extrusion ratio, and its rod length is (extrusion length / extrusion ratio + overpressure Thickness) * upsetting coefficient, where the upsetting coefficient is obtained by dividing the cross-sectional area of ​​the cast rod by the cross-sectional area of ​​the extrusion cylinder.

     The parameters of the aluminum bar, which are calculated by the practical weight method, are: the weight of the aluminum bar = the extruded length * the meter weight of the profile + the residual weight. Therefore, these two have different calculation formulas, and the above conclusions are drawn.

    3. During the operation of the aluminum extrusion press, is it necessary to determine the length of the aluminum extrusion before stretching?

    In the operation of the aluminum extrusion press, before the aluminum extrusion is stretched, the length of the material must be determined first, and then the elongation rate is determined, so that the moving position of the main chuck can be obtained. Under normal circumstances, the elongation rate of 6063T5 is 0.5%-1%, and the elongation rate of 6061T6 is 0.8%-1.5%. If there are special circumstances, it will be considered separately.


    4. What determines the clamping method of aluminum profiles? When the aluminum profile is cooled to how much, the aluminum profile extrusion machine can start the drawing work?

    From a professional point of view, the determination of the clamping method of the aluminum profile is determined by the shape of the aluminum profile. If it is a large-section hollow profile, then a tensile spacer can be inserted, but a sufficient clamping area should be maintained to prevent problems during the use of the extruder. When the aluminum profile is cooled to below 50 °C, the aluminum profile extrusion machine can start to stretch.
