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.
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 ...
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 ]
For rewind slitting the machine used is called a slitter rewinder, a slitter or a slitting machine – these names are used interchangeably for the same machines. "Slitting" refers to the process of industrial cutting the material web in a lengthwise direction, while "cutting" refers to both lengthwise and crosswise cutting operations.
The machine consists of a shear table, work-holding device, upper and lower blades, and a gauging device. The shear table is the part of the machinery that the workpiece rests on whilst being shorn. The work-holding device is used to hold the workpiece in place and keep it from moving or buckling while under stress.
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 ...
Shearing is a kind of mechanical finish in which the appearance of the fabric is enhanced by cutting the loops or raised surface to a uniform and even height. The machine may have a spiral blade similar to a reel lawn mower. [1] [2] A shearing machine can cut the loop or the pile to a desired level. [3]
