Description

-1- TARIFF VIBROFORMING METALS TO GIVE THEM PLASTIC SHAPE. Technical Area 5 The present invention relates to methods and devices for plastic deformation of metals. The invention is particularly useful for ensuring that the surface remains smooth when shaping metals. 10 Vibroforming is a method in which metal is plastically shaped by taking the shape of the desired mold. It is about giving and a new mechanism for doing so. State of the Art Today, various methods are used to shape metals. There are 15 known methods. Work on developing new technical improvements as a result of technical problems in the applications. is being done. In the current known state of technology, sheet metal form forming is conventional. In the methods, flat plate forming operations are performed using four different methods. This is done using the male-female molding method, resulting in a total of male and female molds. Two molds are made. However, sometimes due to machining tolerance errors, sometimes... Due to deformations caused by the mold material during processing, the mold Problems arise due to the lack of fulfillment. Mold costs are also high nowadays. Because of this, a small revision leads to a significant financial loss. However, 25 It is the oldest known method and generally provides a solution in terms of product shaping. It delivers. Stretch forming, on the other hand, allows all metal products to have an inherent elasticity due to their structure. It has a modulus. Thanks to this, there is a 30° shift from the elastic region to the plastic region according to the hook curve. Despite the transition, the product retains its original shape. This feature can be utilized. The product is stretched over a male mold and pressure is applied to the mold. In this method... -2- It creates problems at weak points on the metal, preventing the desired smooth surface from being achieved. By not addressing these issues, their problems cannot be solved. In the Rubber Pad Forming (Elastaforming Method) method, the sheets are mostly used. A shaping process performed when a relief or motif is desired on the surface. 5 This is the method. Mold making processes and costs are very low. To be shaped The product is shaped by being placed between a male stapler and an elastopolymer material. This is ensured. However, due to its intended use, the plate must be flat. Radius It is not suitable for plates in this form. In this case, new technical developments are needed. It is needed. 10 In the hydroforming method, the presses actually take the shape of the container in which the liquid is held. It operates on the principle of a membrane between the product to be shaped and the liquid. It is located there. Thus, it never comes into contact with the hydraulic fluid product. The lower tooth Even if there are negative angles in the mold shape, the movement of the liquid allows the product to reach its permitted 15°C. Shaping can be done using all available methods. However, a serious effort is required for each mold. Investment and high tonnages are required. Sometimes, increasing the size is necessary. The machine power is insufficient. Molding times are very long and costly. The disadvantages of hydroforming presses are as follows: Mold preparation processes take 20 minutes. It takes a very long time. Mold making costs are very high. Mold the logic is that at least one of them is definitely either male or female. It must have been produced. Measures are taken to correct possible errors in mold making. The revisions are very costly. For press power, very high pressure and much more... The need for high tonnage. Work accidents that may occur due to high pressure leaks. 25 The risk is high. The size of the products that can be produced is limited. The need arises for the machine dimensions to grow proportionally with the product dimensions. When the technical problems in these four different production techniques are examined More economical and ergonomic shaping methods as shaping method 30 The need for this search has arisen. -3- In application number US4257251A, a sheet metal workpiece and a patterned mold are described. The workpiece is molded by applying an embossing or cutting process onto its plate. a rubber or other elastomer sheet is placed on the workpiece by being placed on the plate. It is deformed by being positioned and passed between intermittent parallel driven cylinders. A distinctive feature of the invention is that on either side and adjacent to the lower cylinder, there are 5 rubber strips. The mold is designed so that the applied flexible forces do not bend the carrier and the mold plate. load cylinders to support a carrier that supports the plate It is used. However, in this application, the elastomer forming method described above is used. New technical developments are needed to eliminate the problems experienced in delivery. It is heard. The shaping explained here is done up to a certain thickness of 10 The new shape overcomes the problems that arise from surface shaping issues. The development of delivery techniques is becoming essential. Explanation of the Purposes of the Discovery 15 Based on the current state of the art, the aim of the invention is to improve existing structures. eliminating the negative aspects, and plastic shaping of metals using the vibroforming method. The goal is to develop a new mechanism for this. Another purpose of the invention is to form a metal sheet regardless of its thickness. It is the ability to be shaped in that way. Another aim of the invention is to create a device with low hardness in the middle section using the developed mechanism. The material is subjected to a specific force of 25 using a high-hardness material on the outside. The metal part will be shaped by applying vibration, similar to rolling out dough. It is the process of shaping the material to take the shape of the mold. Another purpose of the invention is to shape metal parts by applying force. a new technique that can prevent the formation of surface shaping errors such as invoices 30 The solution is to develop a solution. -4- Another purpose of the invention is to apply pressure to the metal part that is to be shaped. By achieving a force distribution from the center to the sides, similar to rolling dough on metal... The goal is to ensure a smooth surface when molding plastic parts. To achieve the aforementioned goals, the five known branches of technology, thanks to their technical superiority, were used. plastic deformation of metals using vibroforming method that surpasses the current situation and for this purpose A new mechanism has been developed.
