The utilization of molds for the purpose of cold stamping on a press is the primary component of the conventional method that is utilized in the processing of metal sheets. There are numerous advantages to using this method, including high production efficiency and the fact that it is suitable for mass production. In a great number of instances zinc die casting manufacturer, the process of developing new molds for product formation is not only costly, but it is also risky, time-consuming, and lacks flexibility.
This trend led to the development of a flexible production technology that is known as flexible mold technology. This technology was developed in order to accommodate this trend. When it comes to the processing and manufacturing of parts of varying shapes, the fundamental concept behind flexible mold technology is to make use of deformable structures or materials to either completely replace or partially replace traditional rigid molds. This can be done in either a complete or partial manner. An increasing number of individuals are showing an interest in this technology, which is a manufacturing process that is characterized by extreme speed. In this article, a summary and analysis of the most significant technologies die casting defects causes and solutions and development trends of flexible molds are presented. These findings are based on research that was conducted both domestically and internationally. Utilising multiple points as a method for the formation of rigid moulds
It is possible to replace traditional rigid molds with multi-point flexible mold technology, which is also referred to as reconfigurable discrete mold technology. The utilization of this technology involves the utilization of a number of fundamental bodies that are arranged in a regular pattern and can be adjusted in height. The multi-point adjustable envelope surface is formed by the end faces of these basic bodies, which are responsible for the formation of the envelope. Between the years 1985 and 1991, the Massachusetts Institute of Technology (MIT), CyrilBath Company, and the Naval Research Laboratory collaborated by designing and manufacturing a new type of stretch forming discrete mold that is capable cable clamp kit of automatically adjusting the profile. This mold was designed and manufactured by the three organizations. For the purpose of preventing the surface of the sheet from forming, it is necessary for the surface of the sheet to be covered with an elastic cushion layer prior to its utilization.
2. Technology that makes use of a blank holder with multiple points in addition to deep drawing technology that is subject to variable pressure
A technology known as multi-point blank holder variable pressure deep drawing forming has been utilized over the course of the past few years. The moldless forming of sheet metal components is something that can be accomplished with this discrete mold technology at the moment. Additionally, the integration of CAD, CAE, CAM, and CAT capabilities, as well as the automation of sheet metal forming, can be accomplished with relative ease. There is the potential for further development to include the establishment of a moldless factory. Measuring the shape and repeatedly processing the parts until they meet the requirements for shape and accuracy is the process that is being described here. In addition, the fact that this advantage is available is even more obvious.) to serve as the medium through which force is transmitted during the process of forming, and to work cable clamp kit in conjunction with another medium in order to replace the rigid punch or the concave mold. Molding is the process by which a plate is formed, and the action of a force transmission medium is responsible for this formation. The plate can be formed using either a rigid concave mold or a convex mold. With regard to the classification of sheet soft mold forming, there are three primary categories that can be utilized.
Solid soft mold forming, semi-solid soft mold forming, and liquid (gas) soft mold forming are the three categories that fall under this category structure. The differences in the physical properties of the force transmission medium serve as the basis die casting defects causes and solutions for these categories. Rubber molding, which is the most common type of molding, is distinguished by the utilization of elastic materials such as polyurethane rubber as soft molds. Rubber molding is also the most common type of molding.
When it comes to solid medium pressure transmission forming in solid soft mold forming, solid particle pipe forming is a process that involves the utilization of solid particles rather than rigid punches (or elastomers, liquids) in order to create pipes. Another name for this method is solid medium pressure transmission forming. During the process of forming, it is possible to effectively prevent the tube blank from cracking in the thinning area. This is made possible by the fact that the pressure that is applied to the surface of the blank can be controlled. Controlling the order in which the various components undergo deformation is the means by which this objective is accomplished. Through the utilization of this process, it is possible to achieve the formation of tubes that are difficult to deform, possess a high level of strength, and have a low level of plasticity. Manufacturing technology that is at the forefront of improvement. After being pressed into a super-elastic flexible pad by means of a pressure roller, the blank is then contained within the flexible pad during the manufacturing process. This occurs after the blank has been pressed into the pad. It is possible to adjust the pressing depth of the press roller as well as the horizontal displacement of the blank in order to obtain profile bends with varying curvature radii.
This can be done in order to achieve the desired bending profile. In addition, a roll-shaped object that is bendable was used as a forming tool in order to achieve flexible forming of three-dimensional curved panel parts. This was done in order to achieve the desired result. Technology that utilizes multiple points of shaping is combined with this. Through the utilization of multi-point roll forming, it is possible to accomplish zinc die casting manufacturer the process of forming three-dimensional curved parts in a manner that is both efficient and continuous. These parts include spherical parts, saddle parts, twisted parts, disc-shaped parts, cylindrical parts, and free-form surface parts. There is a high degree of fluidity in the liquid force-transmitting medium, and it is distinguished by a pressure distribution that is uniform throughout throughout. Furthermore, the same pressure is applied to areas within the deformation zone that have small deformations as well as areas that have larger deformations. The fact that it is a medium that is between liquid and solid, which is the medium that it uses to transmit force, gives it a set of characteristics that are exceptional to itself.
Due to the superior fluidity of semi-solid materials, the viscous medium is able to better form high pressure in the pressure chamber when compared to solid elastic soft molding. This is because the viscous medium is more capable of forming high pressure. Furthermore, the viscous medium is capable of filling small fillets and complex surfaces effectively, which enables it to avoid local molding. As a consequence of the phenomenon of insufficient pressure to fully adhere to the mold, the shape of the parts that are formed becomes more complicated. In addition, the requirements for sealing are cut down significantly when compared to liquid water or oil.
