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. 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. Aluminum wholesale manufacturers are used to need high corrosion, good weldability and medium -intensity occasions, such as ships, cars, aircraft, low -temperature equipment, TV tower, drilling devices, transportation equipment, missile parts and decks, etc. 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 shape of the shape of the shape of the size refers to the diameter and thickness of the outer circular diameter and thickness of the mold. The size of the mold is judged from 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 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. 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 evaporation area configured by the aluminum row manufacturer is less than the steel tube. 2. Frequently problems in mold design 1. The role of the second -level welding room squeezing the mold plays a vital role in the squeezing production of aluminum profiles, which directly affects the quality of squeezing products. 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. 3. Summary after always studying and accumulating, always inquire about the related mold design materials, optimize mold design after reform and renovation, and verify whether it is victorious through production.
