Welcome back friends. We are studying the subject manufacturing process in this subject. We are studying the farming process, metal farming process. In this we are seeing the sub topic extrusion. A plastic deformation process is in which metal is posed under pressure to follow, to flow through a single or series of dies until the desired shape. The desired shape is produced. The process is similar to squeezing, to paste out of the tube, to paste tube. The general extrusion is used to produce long parts of uniform cross sections. Typical products made by extrusion are railing for sliding doors, tubing, paving cross section, various cross sections, sections, structural and architectural, shapes, doors and windows frames. Ram, it is shown in figure, ram, work and die. The ram is posed with force up and velocity, we work this produce direct extrusion types of extrusion are direct extrusion followed extrusion, which are also called as followed extrusion and direct extrusion, which is also called as backward extrusion, called extrusion and hot extrusion. Direct extrusion, in this direct extrusion, blade is placed in a chamber and pushed through a dial opening. By a hydraulic rig, the one ram or pressing steam dies or machined to the desired cross section. Ram is given with velocity, velocity v and force up, final work is work shape is given as shown in figure, container is also given. Container, liner, billet, die, die, backer, extrusion is given, container is given, cross sectional area of the process is given, pressing steam is given, dummy block is given, container is in next figure, container is given, ram is given with velocity v and force up, final work piece is shaped, material is given, die is given, indirect extrusion, indirect extrusion is in this extrusion, the metal is posed to follow through the die in an opposite direction with the ram's motion. Lower extrusion force as the work billet metal is not moving relative to the container wall, limitations, lower rigidity of hollow ram, difficulty in supporting extruded product as it excites die, as shown in figure, the extrusion process is drawn, commonly used to make wires from round bars, large quantities of wires, rods, tubes and other sections are perused by the drawing process, which is basically a cold working process. In this process, the material is pulled through a die in order to reduce it to the desired shape and size, a typical wire drawing operation once, end of the wire is reduced and purges through the opening of the die, grip and pulled to reduce its diameter. The main figure die is given, drawn wire is given, which is pulled. Drawing is the operation of the cross section of solid rod wire or tubing is reduced, or changed in shape while pulling it to the die. Drawing rods are used for shafts, spindles and small pistons, and as the raw material for a partner such as rivets, glutes, screws, drawing also improves strength and hardness, when these properties are to be developed by cold work and not by subsequent heat treatment. As shown in figure, drawing machines consisting of multiple draw dies, dies difficulty 4 to 12 separated by accumulating drums, is drum, caxton, croise, proper, proper course to draw wires, stock, through upstream die, is die, provides a small reduction to desired total reduction is achieved by the series, by the series, dry materials are given as follows, commonly used materials are tool steels and curvides, diamond dies are used for pine wires, or improved wire resistance, steel dies may be chromium plated, and curvides dies may be coated with titanium nitride. For hard drying, caust steel dies are used, tube drying is given, tube is given, mantle is given, dies is given, tube grippers are given, drop, bench is given, tube drying is also similar to the wire drying except that a mantle of appropriate diameter is required to form the internal hole. The process reduces the diameter and thickness of the tube, tube drying is very similar to wire drying except that beginning stock is tube, it is used to decrease the diameter improve surface finish, improve dimensional accuracy, a mantle may or may not be used depending on the specific process used. Here, here two arrangements are shown in figure with a floating plug and A is with floating plug and B is with moving mantle, thank you.
