Ball forming process and die

Fit. The disadvantage is the complexity mold Results Ke, n} The second operation is also very easy, still use spinning method, the advantages are: simple mold, and the addition of a part to be re-processed,[link widoczny dla zalogowanych], the other parts mentioned above can be used within spinning ball outside the mold parts, do not repeat the manufacture, operation is also very convenient. The disadvantage is: fear of instability within the ball to form a concave, has been calculated that less likely, and therefore it is feasible to use spinning assembly to determine the process route is: Cutting - Spinning (necking) of a bulging - a polished car repair ends - Rotary Ju (assembly). Bearing in mind that the mold assembly forming mold 2 2.1 Figure 2 touch with spinning inside and outside the rotating ball compression mold the neck,[link widoczny dla zalogowanych], installed live using the lathe. Keen interest by the lathe spindle shafts Hing l live, and the other Duanyou lathe tailstock top stand up, spin round on the lance 10 mounted on the turret, fitted with the tube to the mold, after indirect speed and feed rate will be able to 44mm Da shrunk to 36m. On the characteristics of the mold; f1) applications ... t 'ring 2 can be made in Figure 21. Mandrel 2. Anonymous pad 3. Set of 4. Plate 5. Screw 6. Spring 7. Nut 8. Open washer 9. Nut l9, foot roller frame 11. Qiang pumping 12. Roller i: necking length with inner and outer ball (after the calculation of the necking part of the ball slightly longer 2mm) (2) sets of 3 larger than the inner diameter of the outer diameter of the nut 9, so easy to operate,[link widoczny dla zalogowanych], dismantle the system pieces, just slightly loosen the nut 9, the opening out of washers 8, rustic Jazz cut out sets of three sub-components. (3) and actinium plate 4 by a spring clamping device consisting of so Reed has always been able to suppress the system ran well to ensure the spinning to the correct location. Flea : Phoenix 81. Mandrel 2. Open Sook Nang 3. Nuts 4. Roller frame 5. Pin 6. Figure 3 shows the roller assembly of the spinning mold, the core chapters pay attention touch with the rest of the outer part 1 of Figure 2 can be borrowed, thus saving manufacturing costs. Shaft parts 1 and parts of necking with a certain requirements to ensure Spinning _ not to have had the carving deflection. . '. 2.2 touch with bulging bulging mode Figure 4, mounted on the bed with red 60t. The ball is the key to mold forming such molds usually installed in bed with dual action punch, punch by the double-action car I slip under the busy movement of the slider expansion discharge management. Since I did not double-action press plant, so the model can only be considered on its structure. The next course of action to help; when driving on the punch die down then the slider, the pressure and die lemon 2 l4 first contact, the capacity of the die 2 and Taiwan, according to a press paste, followed by polyurethane rubber 7 and the positioning block 4 connected Lu began bulging to Bian point. Chao Gao expansion completed, red seats Labour | I18 No. 4 total block of lead on the 14d model return, the return is about to put in place, the pull plate 3 driven cross arm 17 and ejector die from 2 to 16N unloading 'material. The mold design points: (1) to consider the die bulging _ A 2 from the three combined into, for ease of operation, so the design of a spring hoop 2O. (2) die down on the plate must ensure that the first 14 』t live 2 die, otherwise it is difficult to ensure the quality of bulging. (3) promote cross arm pull plate 3 and the mandrel l6 l7 discharge must be left to die 2 pieces 7 a distance exceeding the height of the die itself, otherwise the die will not get out. (4) expansion outside the ball, simply replace the die 2 and 4 of the positioning block port J. Ball shape to the assembly from the parts to complete, the actual rejection of only two sets of molds, because most of the parts can touch 21 with the rear bracket stamping Suzhou Metallurgical Machinery Factory Dan Internet ink D jc 'rear bracket part shown in Figure 1 said that as a caster frame and cut off the feet of little ordinary caster frame, but the wall thickness of thick (6 = 3mm), even the existence of two ear drum, the strength and stiffness are all better (material: 0sA1 cold rolled sheet) , which can withstand greater loads. But such small pieces of thick-walled, multi-woo was forming processes. And its rough size, proud time to go through test mode in order to identify,[link widoczny dla zalogowanych], analyze about part A one ear attached to the circular cylindrical wall of the cylinder _ boat made by stretching and bending at some foam ear by stretching, - grave before bending to stretching, bending in the tension in the Health Department did not want to be stretched Caixing. As for the two: le ear pin to wear at the two holes, and there is a parallel requirement made of l as the final, Shang out by the horizontal hole at the same time, can guarantee to meet the requirements; but this is confined to the sides of the inner ear little space,[link widoczny dla zalogowanych], to open a hole large enough to drain material was very difficult, so only on the shape when washed before blanking {Rb. Later proved also to achieve the above requirements. Let simmer for stamping parts can be located: blanking, bending, stretching tendons turn, red bottom shape. A total of six processes. 1 blanking: Rack casters to start the calculation of size bird with only C-C segment (see Figure 2), ie 5; × 10ram cylinder, light stretching in the G-C B-B section to section, the juvenile sub- Although derived from the stretch, but, and
