In order to make the blank support plate 3 abut against the sub-blank support plate 5, the first gap H2 of the billet support plate 3 and the carrying device 7 is set to be larger than the walking interval. The U system of the assisting gap and the motion initiation gap H2 (that is, to what extent is the motion initiation gap H2 larger than the rib gap H1 > must be set so that it can exert a full noise (silent) effect. When the blank support board 3 When actuated by the operation pattern 13, the spring 11 is deflected so that the lower part of the blank support plate 3 abuts on the auxiliary blank support plate 5 and the chess set 7 abuts the thin plate 41 on the blank support plate 3. This state is shown in Fig. 2. At this time, the chess set 7 is not in contact with the stationary blank support board 3 but is in contact with the thin sheet 41 on the moving blank support board 3. It is also said that the chess set 7 does not It is in contact with the stationary sheet but in contact with the walking sheet 41, so it seems that no snoring sounds occur. _Hou Shangqi 6 followed the descent of the mine, and when it reached one of the dead points shown in Figure 3, it was pulled. After the processing is completed, the processed part Ϊ is formed. When the chess 6 rises, the processed part V is opened by the punch 2 by the blank support plate 3. Because the chess set 7 is provided with a vent hole 8, when the processed part 落 falls due to self-reflection, Negative pressure can be avoided between processing W and chess set 7. In addition, cadmium (not shown) can be used to push the pressure The workpiece W is ejected from the outside of the chess set 7. The fourth display shows that the guide plate 51 is mounted on the cross piece 7 with bolts 52. This guide plate 51 can slide the blank support plate 3 to position the blank support plate 3. -9 -This paper size is in accordance with Chinese National Standard (CNS) A4 specification (210X297 mm) I Ί-—J 111 ———— — — Binding 11 Binding — 11 n line <., (Please read the precautions on the back before this Page) Printed by the Central Standards Bureau of the Ministry of Economic Affairs, Shellfish Consumer Cooperatives, printed A7 B7 V. Description of the invention (7) In addition, the guide bar 53 is mounted on the sub-blank support plate 5 using the «plug 54, whereby the guide bar 5 3 makes the blank The branch support plate 3 slides to position the auxiliary blank support plate 5. If there are various specifications of the driving stalk 13, the bracket 14, the operation cam 31, etc. (including «child 21, 22, turn 17, extension spring 20 and support Table 32) can easily change the existing drawn chess set into a silent structure chess set. Furthermore, it is even more possible to lay a urethane resin sheet under the blank support board 3 or on the auxiliary blank support board 5 »Mute (silent) effect. In addition, the above description is that the lower lever 1 is provided with the activation lever 13 and the bracket 14 and the upper wedge 6 An example is provided with an operation cam 31. However, as shown in 5th, even if the starting lever 63 is installed on the chess 6 and the bracket 64 is installed on the chess 1, the same mute effect can be achieved. In this case, although The pad 51 is healed by the Mi 52, but since the Mi 51 is abutted against the thin plate 41 after being actuated by the actuating lever 63 and the action cam 81, a mute effect can be obtained. In addition, according to the present invention, when the thin plate is being bent or One "When bending down and another bending up, if a sheet or machined part is held by a silent device before it is actuated and then held, the silent (silent) effect can be obtained. As mentioned above, the present invention is A blank support plate that is embedded in the weighing head and is thinly lifted and supported by the street pound, and a chessboard that is arranged on the opposite street, and a thin plate is placed on the blank support plate that rises from the street pin, so that the crossbar is lowered and the blank is supported. In the drawing chess set where the sheet and the cross piece hold the thin plate, and the sheet is drawn by the weighing head, Fu You: sets a sub-blank support plate between the slow pin and the blank support plate, and the sub-blank support plate and Intermediate strength between blank support boards «Between the sub-blank support board and the sub-blank support board-10- This paper size applies to the Chinese National Standard (CNS) A4 specification (2ΙΟχ 297 mm) ---------- installation ---- --ίτ ------ ^ (Please read the note on the back page) A7 B7 printed by the Ministry of Economic Affairs and the Central Bureau of Standards Consumer Cooperatives V. Description of the invention (8) Set the rib clearance of the blank support board, At the same time, a supporting rod is set on the sub-blank support plate to rotate freely. A driving rod that pushes the blank supporting plate to move it before carrying a thin plate that abuts against the blank supporting plate, and is arranged at a position opposite to the chess equipment of the driving rod. The chessboard abuts the blank support plate after the blank support plate is actuated to make the chess piece abut the blank support plate as the silent structure of the drawn chess piece, so the chess piece comes into contact with the blank support The thin plate on the board can greatly reduce the occurrence of noise when compared with the horizontal plate abutting the thin plate on the stationary blank support plate. In addition, according to the present invention, when the activation lever and the turning cam are unitized into K, it can be used as a conventional ballless structure for drawing chess equipment. In addition, according to the present invention, when the inclination angle of the cam surface of the oscillating cam is changed differently, the operating speed of the blank support plate can be controlled. Also, since the silent starting device of the present invention is installed on the auxiliary blank support plate and In addition, after the blank support plate is driven, it is brought into abutment with the sub-blank support plate. Therefore, it is easy to improve the existing drawn chess set to a silent structure. Also, the silent operating device of the present invention is The driving cam of the M moving rod is used as a cam, so the existing drawing beam can be improved to a silent structure. In addition, since the silent structure of the present invention includes chess and chess, an operating cam is carried underneath, and an actuating lever is provided at the upper die position opposite to the above operating cam, so the chess can be reduced. The pressure of the voice and other voices that occur in the voice source. In addition, since the present invention is a press machined by holding a thin plate or a workpiece, the thin silent device is operated before the thin plate or the workpiece is held, and therefore, no effect is obtained on the bed. -11- The size of this paper applies to China National Standard (CNS) Α4 specification (210 × 297 mm) — ：-: ------- ^ ------, order ------- 0 ( Please read the precautions on the back of this page before printing this page) Printed on the A7 B7 by the Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economy The longitudinal section of the main part of the state _; The second part shows the state of the main part of the state that the blank support plate of the present invention is in contact with the auxiliary blank support plate after the blank support plate starts to move. 3rd _ shows that the upper cross is further lowered from the state of the second drawing, and reaches the longitudinal letter of the main part of the state when the bottom dead point of the drawing process is completed; 4th shows the draw cross of the present invention The state of the point, in which the head shows the state where the sub-blank support plate is positioned by the cymbal plate.
