Aluminum Profile Extrusion Mold Design Analysis-WJW Aluminum Supplier Aluminum

In recent years, with the rapid promotion of the large -scale infrastructure investment and industrialization process in my country, the output of the aluminum profile industry has increased rapidly, and my country has also become the world's larger aluminum profile production base and the market spending market. After nearly 10 years of high speed, my country's aluminum profile industry has entered a new stage of development and showed many new development trends. Moreover, with the agile development of industries such as construction, transportation, automobiles, and solar energy and LEDs, the high precision and high functional requests of aluminum alloy squeezing products are once and for all. There are many shortcomings. The most widely used type of non -ferrous metal structure materials in the aluminum alloy profile industry, in aviation, aerospace, automobiles, machinery manufacturing, ships, buildings, decoration. Therefore, in order to get high -quality profiles, you must always study and accumulate, reform and refurbish in production and life. Mold design is an important link. Therefore, the design of the mold design of the squeezing profile must be analyzed, and the problem is gradually solved through the actual production. 1. Six points of the design of aluminum profile molds 1. Analysis of the size and deviation of the squeezing parts of the aluminum squeezed parts is determined by the mold, extrusion equipment and the remaining process factors. Among them, due to the change of mold size changes, the cause of the changes in mold size is: the elastic deformation of the mold, the heating of the mold, the data of the mold and the manufacturing accuracy of the mold, the molding of the mold, etc.

(1) The choice ratio of the tonnage of aluminum profile squeezers is difficult to redeem the mold to implement the mold by numerical. In individual, the squeezing ratio is practical between 10-150. The squeezing ratio is less than 10, and the product mechanical machine energy is low; on the contrary, the squeezing ratio is too high, and the product can easily show the shortcomings of nominal rough or angle deviation. Solid materials are often recommended to squeeze to about 30, and the hollow profile is around 45. (2) The shape size of the decision of the shape of the shape is the diameter and thickness of the outer circle of the mold. The size of the mold is judged by the size, weight and strength of the section of the profile.

2. When squeezing the size of the mold size, when calculating the size of the mold pores, it is important to consider the chemical composition of the squeezing aluminum alloy, the shape of the product, the nominal size and its tolerance, the squeezing temperature, and the mold data and being by the mold at this temperature and the being being being quilt at this temperature. The line expansion coefficient of squeezing alloys, the characteristics of the size and shape on the product section, and the changes when stretching straight, the size of the squeezing pressure, and the elastic deformation of the mold.

3. The flow speed of fair adjustment of metal. The so -called fair adjustment is that under the fantasy situation, every major point on the section of the product should flow out of the mold hole at the same speed. 4. Ensure sufficient mold strength because the premise of mold work during squeezing is very bad, so mold strength is a very important issue in mold design. In addition to the position of the formation holes, choosing suitable mold data, and the halter structure and appearance of the fair design, the strength of the correct sitting pressure and the dangerous section of the school nuclear check is also very important. 5. The working band width size Judgment the workbone of the diversion combination model is much more complicated than judging the semi -mode work band. Not only should we consider the thickness difference between the wall and the distance from the center of the center. The mold holes under the diversion bridge, because the metal flows into difficulties, the workband must consider minimizing. 6. Modern hole empty knife structure Model holes empty knife is the structure of the mixed -end cantilever support of the mold hole work. The most widely used type of non -ferrous metal structure materials in the aluminum alloy profile industry, in aviation, aerospace, automobiles, machinery manufacturing, ships, buildings, decoration. When the wall thickness of the profile is T 2.0mm, a straight -empty knife structure can be adopted; when T

2. Common problems in mold design 1. The role of squeezing molds in the second -level welding room plays a vital role in the squeezing production of aluminum profiles, which directly affects the quality of squeezing products. However, in actual production, the design of squeezing molds is more to rely on the lessons of designers. The quality of mold design is difficult to guarantee, and it is necessary to repeatedly test the model and modify the mold. 2. The role of secondary diversion is in the design of squeezing molds. For solid profiles with great differences in wall thickness, second -level diversion is adopted. Example: The initial mold design consists of individual molds and mold pads. It is not fantasy to go on the machine in the previous machine. The angle is small and the thin -walled parts are super thin and super small. Even if the mold returns, even if the thin wall is increasing, the low work zone is still fantasy. 3. Summary after learning and accumulation, always inquiring about related mold design materials, optimized mold design after reform and renovation, and verifying whether victory through production.
