Types of blanking dies There are two general types of blanking dies: the drop through dies and the inverted dies. Drop through dies: In this die, the die block assembly is mounted on the bolster plate or the press bed and the punch assembly on the press slide. The blank drops of its own weight through the die opening and the clearance provided in the bolster plate and press bed.

Blanking and piercing
Show all documents Design and Analysis of Blanking and Piercing die punch In this project a die punch for blanking and piercing operation is designed and analysed for component. The theoretical calculations were done for calculating cutting force, tonnage required, fatigue life and stresses. The 3D models created in Catia-V5 and analysis is done on Ansys The main objective of the project is to improve productivity and reduce production cost. The exiting cycle time for blanking and piercing operation is approximately four minutes which manufacturing cost is around six rupees. After implementation of this project we can expect the cycle time will be 30 to 40 secs and cost will be around 1.
Piercing, punching and blanking are three common machining processes that are used to manipulate raw metal, such as sheet metal. All three processes require the use of a machine, which in some way deforms or alters the physical properties of the raw metal. While similar, though, piercing, punching and blanking have different functions. Piercing is a shearing process in which raw metal is pierced with a machining tool, resulting in the creation of a circular or other shaped hole. As the raw metal is pierced, the metal from the newly created hole is considered scrap. The piercing machine forces a tool, known as a blanking punch, through the sheet metal.
Stamping dies are used with a press ,  as opposed to. Like molds, dies are generally customized to the item they are used to create. Products made with dies range from simple paper clips to complex pieces used in advanced technology. Continuous-feed laser cutting may displace the analogous die-based process in the automotive industry,  among others. Blanking and piercing are two die cutting operations, and bending is an example of a die forming operation.
Compound die generally consist of blanking and piercing operation which are performed in single press stroke. This design tool is manufactured.

This article discusses the presses, auxiliary equipment, and dies used in the blanking and piercing of commonly used magnetically soft materials, namely, low-carbon electrical steels and oriented and nonoriented silicon electrical steels. It describes the effect of stock thickness and work metal composition and condition on blanking and piercing. The article provides an overview of the influence of burr height on stacking factors and presents a discussion on the lubrication and core plating of electrical steels that ease the process.

In order to improve the life of final-forming and sizing rolls, the areas of these rolls, Elliptical vibration cutting, which has been proposed by the authors, is applied to ultraprecision diamond cutting of hardened steel in the present research. Also the energy required ED for dynamic blanking was greater than that for the corresponding quasi-static process ES for all three materials at all the temperatures investigated. Punching is a forming process that uses a punch press to force a tool, called a punch, through the workpiece to create a hole via shearing. Punching is applicable to a wide variety of materials that come in sheet form, including sheet metal, paper, vulcanized fibre and some forms of plastic sheet.

Blanking and piercing are shearing processes in which a punch and die are used to produce parts from coil or sheet stock. Blanking produces the outside features of the component, while piercing produces internal holes or shapes. The web is created after multiple components have been produced and is considered scrap material. The "slugs" produced by piercing internal features are also considered scrap.
Our robust, quality-driven stamping capabilities include:. Both blanking and punching are material forming processes that involve the precise removal of material from a workpiece. The main difference between the two processes lies in the end product produced. On the other hand, in punching operations, the material removed is discarded, and the final product is the remaining material which then undergoes further processing. Another difference between the two processes is how manufacturers approach processing the initial sheet material.
Types of blanking dies There are two general types of blanking dies: the drop through dies and the inverted dies. Drop through dies: In this die, the die block assembly is mounted on the bolster plate or the press bed and the punch assembly on the press slide. The blank drops of its own weight through the die opening and the clearance provided in the bolster plate and press bed. This design is economical to build and maintain and is fast in working. Inverted die: In this die, the punch becomes the lower stationary part and the die is mounted on the ram. This die is complicated, costly and slower in operation.
