Die Back Plate:This plate prevents the hardened Die inserts penetrating into bottom plate. Guide Pillar & Guide Bush : Used for alignment between top and bottom halves of the press tools. Bottom plate:It is used to hold bottom half of the press tool with press slide. Stripper plate: it is used to strip off the component from punches.
Shearing, also known as die cutting, [1] is a process that cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations. [2]
A typical compound fine blanking press includes a hardened die punch (male), the hardened blanking die (female), and a guide plate of similar shape/size to the blanking die. The guide plate is the first applied to the material, impinging the material with a sharp protrusion or stinger around the perimeter of the die opening. Next, a counter ...
Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining. [1] This could be a single stage operation where every stroke of the press produces the desired form on the sheet metal part, or could occur through a series ...
Shearing – punching, stamping, scissoring, blanking; Abrasive material removal – grinding, lapping, polishing, water-jet; Heat – flame cutting, plasma cutting, laser cutting; Electrochemical – etching, electrical discharge machining (EDM), electrochemical machining (ECM) Every method has its limitations in accuracy, cost, and effect on ...
Jumia's share price sank more than 50% in one week after the report was published. [74] Citigroup, one of Jumia’s IPO underwriters, released a report debunking most of Citron’s allegations but noted that, “Jumia could do more to provide disclosure on some aspects of its operations, as a matter of transparency and best practice.” [75] [76]
An alligator shear, historically known as a lever shear and sometimes as a crocodile shear, is a metal-cutting shear with a hinged jaw, powered by a flywheel or hydraulic cylinder. Alligator shears are generally set up as stand-alone shears; however, there are types for excavators. The jaw size can range from 4 to 36 in (100 to 910 mm) long.
A machine tool is a machine for handling or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformations. Machine tools employ some sort of tool that does the cutting or shaping.
