aluminum profile extrusion press machine plant line, which is one of the extrusion machine, but also website products and keywords, so in learning requirements, it is not to pay attention to, and, to achieve this comprehensive degree, so it can do.
1. The processing method of the aluminum profile extruder of the aluminum forming equipment is a plastic processing method? In addition, does this kind of extruder have accessories?
The processing of aluminum profile extrusion press machine plant line, from a professional point of view, it is to exert external force on the metal blank in the extrusion cylinder, so that it flows out of the specific die hole, and then, to obtain the required section shape and size of the product. So, from its definition, its processing method, is a plastic processing method. And this kind of extruder, there must be accessories, generally speaking, is a thimble, scale plate and skateboard and so on.
2. Aluminum extruder, the use of volume method and practical weight method to calculate aluminum bar parameters, in the calculation formula is the same?
In the aluminum profile extrusion press machine plant line, the calculation of the parameters of the aluminum bar, there are two kinds of volume method and practical weight method, and their corresponding calculation formula, is not the same. In the volume method, the calculation formula of the extrusion length of the aluminum rod is (the length of the aluminum rod/upsetting coefficient – the remaining thickness)* extrusion ratio, and the rod length is (the length of the aluminum rod/extrusion ratio + the remaining thickness)* upsetting coefficient, which is obtained by dividing the sectional area of the casting rod by the sectional area of the extrusion cylinder.
Aluminum bar parameters, its use of practical weight method to calculate, is: aluminum bar weight = the length of the extrusion * profile meter weight + pressure weight. Therefore, these two are different calculation formula, and reached the above conclusion.
3. In the operation of aluminum extruder, whether to determine the length of aluminum before drawing?
In the operation of the aluminum profile extrusion press machine plant line, the aluminum profile is to determine the length of the material before stretching, and then determine the tensile rate, so that the main collet can be moved. Under normal circumstances, the tensile rate of 6063T5 is 0.5% — 1%, and the tensile rate of 6061T6 is 0.8% — 1.5%. If there are special circumstances, it will be considered separately.
4. What determines the clamping mode of aluminum profiles? When the aluminum is cooled to how much can the aluminum extruder start to stretch?
The clamping method of aluminum profile is determined by the shape of aluminum profile from a professional point of view. If it is a large section hollow profile, then the tensile pad can be inserted, but to maintain enough clamping area, in order to prevent problems in the use of the extruder. When the aluminum profile is cooled to below 50℃, the aluminum profile extruder can begin to stretch
