Base flange heaters,[link widoczny dla zalogowanych], pressure form, pressure bars Compound Die

I Received a c leek: l995 on January 26 in Figure 1 heater base, No. 3 Total 18 111 pieces of used parts from under 8 will be out on the top, the whole process of forming and unloading parts is Taiwan reasonable. But this highly complex structure of the mold closing large, time-consuming manufacture materials: As a top edge and large pieces of rubber f binder binder only use a large area of rubber. 7 pieces have sufficient force to push pieces) produced by pressure on the sliding mode is not easy nowadays mode,[link widoczny dla zalogowanych], the mode difficult (if you increase the guide pins and bushings, mold will make a greater volume), and thus will increase the equipment tonnage. At the same time. After positioning part 12 on the floating pieces. Stamping, due to mechanical vibration and the asymmetric shape of the mold before, the pressure piece 7 pieces of material force and the top 12 pieces of strength is not completely balanced. In the binder process. Scratch the part on the two positioning rectangular L. Figure 3 is installed along the mold structure. Figure 2 The difference is: If parts of the gap 13 and 8 smaller pieces, you can improve the position. However, due to the larger of the lower die mold more difficult. After careful consideration, the use of the mold structure in Figure 4, the choice of 1600kN punch, according to the press structure, fighting through the pieces of 4 modules and punch each slide on connections, while ensuring a reliable shape. Has the following design features: f1) as part positioning and placed pieces of 9, the process of binder did not float, so positioning and reliable. r2) is the outer edge of the flange part of the flange. So. Flanging, pressure form, beading time. Piece 7 on the part of the package tight parts of the parts is greater than 9, the package tight force, a model, the part stuck in the mold,[link widoczny dla zalogowanych], pieces of eight pieces of 1 through 7 in part from the pieces of shot, unloading parts organization is simple, which of the simplifying the entire mold structure. It is noteworthy that the rational use spring 2, which has two effects; ① before the compression flange part; ② to keep the process of playing pieces 8 pieces of the balance and smooth. Use force if the pieces of 2 is too small, would not achieve the effect: If the force used pieces of 2 too large, then the mold will part when the mold and wrap the pieces left in the next roar so selected four springs, located in the symmetrical mode work on the angular position of the total stretch is 8o ~ 100kN. f3) because no top-FORCE, binder force is also smaller under the model is simple, easy to use on the model. f41 small size as beading beading punch in order to ensure sufficient rigidity to the upper part of the appropriate size increased, as shown in Figure 5. Meanwhile, pieces of 9 blocks from the fight, beading and beading die area with wire cutting punch, it is easy to manufacture. 6789101112l314t00f0 』6f ring 2 conventional mold structure 1. Limit block 2. 3 Arrow punch pressure connection plate 4. Almost 5 fixed on the mold die plate 6, 7. 8 pieces of plate punch unload assembly 9. Plate 1O. The following template u. Pins 12.

Playing pieces of plate 9. Punch assembly l0. The following template l1. Pins I. Xi, 1 + No. 3 Total 181 special elliptical, 13 easy to get a good beading thousands of shapes. Figure 5 beading punch (5) In order to reduce the contact of the upper and lower mold rigid control of pieces of equipment needed tonnage, size = 71, the thickness of the rigid contact with the mold before the part in the pieces of the trip is less than 7 rated tonnage of the press to the next dead point of the maximum distance (ie less than lOmm); same time, the pieces of 9 on the production of 0.2 ~ 0.4mm deep to avoid the empty slot is shown in Figure 6 so that the impulse to make rigid contact pressure set _ in the translation side, pressure form,[link widoczny dla zalogowanych], pressure deformation of reinforced parts, improve the forming quality. With this mold structure, through the use of satisfactory results obtained. Figure 6 a r86 3g punch components Xiang Yuan. - Rod shaped state Jingdong Bending Die Machine Factory (Gansu Dingxi 743000) l shown in Figure victory rate of parts and materials for the 14mml ~ JQ235 ~, March 200O pieces. . . I_ can be seen from Figure 1 ', the part is a rod, curved part of the size of a very irregular, and there are 3. The elbow. If the cold bending. Since spring, part size is difficult to guarantee. And the mold structure complex and require processing of large-tonnage presses. If the heating curve. Bend will have a deep Jishang phenomenon, and elbow 3. Difficult to heat a mold forming is also very convenient. Compared by a variety of programs, end units of existing equipment status, using the technical rules are: income and Date: 9B on January 16 laps 1 Parts
