Optimization and Improvement of Aluminum Profile Extrusion Quality and Yield-WJW Aluminum Supplier Aluminum

Because the specifications of aluminum profiles are diverse, and the data flow is complicated in the squeezing process, and the loading conditions of the squeezing molds are bad, making the development of aluminum profile squeezing products and the design of molds a difficult task. The most widely used non -ferrous metal structure materials in the aluminum alloy profile industry, in aviation, aerospace, automobiles, machinery manufacturing, ships, buildings, decoration. The traditional production model of dependent lesson design and test mode repairs can no longer be satisfied with the need for ancient economic development. In terms of effectiveness is life, quality is the key market economy environment, aluminum profile squeezing production enterprises is more important to improve the victory rate of mold design and processing, and the output and finished product rate of squeezing. In the production of aluminum and aluminum alloy semi -finished products, squeezing is one of the important forming processes. The quality of squeezing molds and the speed of squeezing speed directly affects the product virtue and output of aluminum and aluminum alloy squeezing production enterprises.

In this case, how to improve the productivity of the squeezer is not too late. There are many ways to improve productivity. Progressive installation levels, improvement of workers' quality, and progressive governance of water are all effective methods.

1. Important factor affecting product output and quality

1. The importance of the quality of aluminum sticks

For aluminum profiles with high quality requests, the quality of aluminum rods directly affects the quality and output of the product. High -quality ingots with alloy, grain, refined, and homogeneous ingots may reduce the loss of the mold, and improve the effectiveness. Production time, thereby improving the squeezing speed to achieve larger output. The most widely used non -ferrous metal structure materials in the aluminum alloy profile industry, in aviation, aerospace, automobiles, machinery manufacturing, ships, buildings, decoration.

2. Progressive equipment and high -quality workers are the prerequisite for progressive output

For the output of progressive squeezing products, progress plays a vital role in progressive equipment, high -quality workers, and ancient scientific governance.

3. The importance of mold

The fair mold design, timely nitrogen the hardness and smoothness of the workband of the molding mold, the number of landing changes, reducing non -working hours, and improving the yield of the product of the product. It is very important to achieve a large output.

4. The important connection between temperature control and progressive output

Generally, if it is not a stoppage time, the larger output is important to the squeeze speed, and the latter is subject to four factors, three of which are fixed. Compared with the latter factors, the temperature and control level are variable.

The previous factor is the squeezing force of the squeezer. The squeezing pressure can be squeezed smoothly when the temperature of the ingot is low; the second factor is the design of the mold. The temperature of the passing aluminum alloy rises 35-62 C; the third factor is the characteristics of being squeezed alloys. It is an unknown factor that is limited to squeeze speed. The quality will fall, the mold marks are significantly worse, and even appear sticky aluminum, concave marks, micro -cracks, tearing, etc. Compared with the latter factors, the temperature and control level.

If the squeezing pressure of the squeezer is not large enough, it is difficult to squeeze smoothly or even show the scene of the plugging model, and the temperature of the ingot can be improved, but the squeezing speed should be lower to prevent the export temperature of the data to prevent excessive export temperature of the data. high. Each alloy has a specific and better squeeze (ingot) temperature.

The actual production proves that the temperature of the ingot is better at about 430 C (when the squeezing speed is 16mm/s). The output temperature of the 6063 alloy profile must not exceed 500 C, and the output temperature of the 6061 alloy profile is better than 525 C. The small changes in the temperature of the outlet will also affect the output and quality of the product.

The temperature of the squeezing cylinder is also very important. In particular, the temperature of the warm -up stage should be increased. It should avoid excessive thermal stress between the layers. It is better to increase the squeezing cylinder and the shot to the working temperature at the same time. Preheat the heating rate must not be greater than 38 C/h. The better preheating standard is: rise to 235 C, 8h thermal insulation, continuously heating to 430 C, and after 4H before he puts it into work. This can not only ensure uniform temperature internal and external temperatures, and have enough time to eliminate all internal thermal stress. Of course, heating and extruded in the furnace is a better preheating method.

In the squeezing process, the temperature of the squeezing cylinder should be 15-40 C than the temperature of the ingot. If the squeezing speed is too fast, and the temperature of the squeezing cylinder rises to the temperature higher than the temperature of the ingredients, it is necessary to make the squeezing tube temperature landing. Why is it a troublesome job and the output will fall. In the process of production speed recovery, sometimes the heating element controlled by an electric puppet will be cut off, but the temperature of the squeezing tube is still picking up. If the temperature of the squeezing cylinder is higher than 470 C, the finished product will rise. The temperature of the squeezing cylinder of the fantasy should be judged according to different alloy.

When producing high -quality high -quality nominal profiles, the temperature of the squeezing pad should also be strictly controlled to reduce the inconsistency of the nominal tone. The quality of the fixed squeezing pad is much better than the activity. It can accumulate more calories. Therefore, it can land at the end of the end of the ingot, reduce impurities into the profile, and help improve the output.

The mold temperature plays an important role in obtaining a high output, and it must not be lower than 430 C; on the other hand, it must not be too high, otherwise, how can the hardness may fall, and at the same time, it will produce oxidation and important in the work zone. During the heating process of the mold, it should be avoided by the mold, hindering the smooth air. It is better to take a box -type heating furnace, each mold is placed in a separate box.

The temperature in the squeezing process of the ingot can be increased by about 40 C or higher, and the increase is important to determine the mold design. In order to obtain a large output, the temperature must not be ignored. Each temperature should be recorded and strictly controlled to find out the large output of the machine and various temperatures.

Later, the employees of the squeezing production plant should keep in mind: the exquisite control of temperature is crucial to progressive output.

2. Important product output and quality of quality

Because product output and quality are important depending on the original data, equipment and molds, suitable process parameter settings, and work quality. The specific ways to improve product output and quality, and the amount of finished products are as follows:

High -quality ingots that choose alloy, grain, refined, and homogeneous;

Optimize the design of the mold, timely nitride the hardness and smoothness of the workband of the mold, landing the number of molds, reducing non -working hours;

Leap the ingot blank to reduce the number of residues;

Use hot cutting to make metal revenue improve;

Saw at the welded at the profile, choose the suitable ingot length and squeezing length of the decision;

The temperature of the landing ingot is to ensure the export temperature of the squeezing speed. The most widely used non -ferrous metal structure materials in the aluminum alloy profile industry, in aviation, aerospace, automobiles, machinery manufacturing, ships, buildings, decoration.
