Description

Technical Field

[0001] The invention relates to the technical field of cylinder gasket stamping, in particular to an automobile cylinder gasket stamping die based on elastic blanking. Background Art

[0002] The automobile cylinder gasket is located between the cylinder head and the cylinder block, also known as the cylinder bed. Its function is to fill the microscopic pores between the cylinder block and the cylinder head, ensure good sealing at the joint surface, and then ensure the sealing of the combustion chamber to prevent cylinder leakage and water jacket leakage. The processing of automobile cylinder gaskets requires the use of stamping dies. Stamping dies are a special process equipment for processing materials into parts in cold stamping processing, called cold stamping dies. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the required parts.

[0003] During the stamping process of the automobile cylinder gasket, the automobile cylinder gasket needs to be manually placed between multiple limit rods on the top of the fixed die. The multiple limit rods are distributed on the outer ring of the automobile cylinder gasket and are used to limit the automobile cylinder gasket, so that the automobile cylinder gasket is in the correct stamping position every time.

[0004] However, after the cylinder gasket is stamped, it will stick to the top of the fixed die, and due to the presence of multiple limit rods, people can only take it out by moving it upwards. On the other hand, since the cylinder gasket is thin, the contact area between the worker's hand and the outer ring of the cylinder gasket is small, which is prone to slippage, resulting in the need to grab the cylinder gasket multiple times. The cylinder gasket is located under the moving die, and the worker's hand is under the moving die for a long time, which increases the danger. Summary of the invention

[0023] See also Figure 1 As shown, a stamping die for automobile cylinder gasket based on elastic blanking is provided, comprising a movable die 102 arranged at the bottom of an upper die plate 100, and a fixed die 103 arranged at the top of a lower die plate 101, wherein the movable die 102 is located directly above the fixed die 103, and a driving mechanism, such as a hydraulic press, is arranged at the top of the upper die plate 100, and the upper die plate 100 is driven downward by the hydraulic press, so that the movable die 102 at the bottom of the upper die plate 100 moves downward to the top of the fixed die 103, thereby stamping the cylinder gasket 200 at the top of the fixed die 103. However, in combination with Figure 3As shown, the top of the fixed mold 103 is provided with a plurality of fixed rods 110 and movable rods 111 located on the outer ring of the cylinder gasket 200, wherein the fixed rods 110 are fixedly arranged on the top of the fixed mold 103; the movable rods 111 are relatively arranged on both sides of the cylinder gasket 200, and at least two movable rods 111 are arranged on each side of the cylinder gasket 200. Figure 4 As shown, the movable rod 111 is longitudinally slidably arranged in the slide groove 120 opened at the top of the fixed mold 103. In addition, the bottom of the movable mold 102 is provided with a depression corresponding to the fixed rod 110 and the movable rod 111, so as not to affect the contact between the movable mold 102 and the fixed mold 103.

[0024] Combination Figure 2 , Figure 4 as well as Figure 6 As shown, the top of the fixed mold 103 is provided with piston chambers 105 on both sides of the cylinder gasket 200, and the bottom of the movable mold 102 is fixedly provided with a piston 104 that can extend into the piston chamber 105; an air supply channel 122 is provided between the piston chamber 105 and the slide groove 120 to connect the two; a side rod 112 located below the cylinder gasket 200 is fixedly provided on the side wall of the movable rod 111, which is used to lift the cylinder gasket 200; an adjusting mechanism 150 is rotatably provided in the piston chamber 105, and the adjusting mechanism 150 includes an air supply hole, and the adjusting mechanism 150 has an initial state and a rotating state; When the piston 104 moves down into the piston chamber 105, the adjusting mechanism 150 is in an initial state. In the initial state, the air supply hole and the connection between the piston chamber 105 and the air supply channel 122 are misaligned, so that the gas is compressed in the piston chamber 105; when the piston 104 moves up and leaves the piston chamber 105, the adjusting mechanism 150 is in a rotating state. In the rotating state, the connection between the air supply hole and the piston chamber 105 and the air supply channel 122 is connected, so that the compressed gas in the piston chamber 105 enters the slide groove 120 through the air supply hole and the air supply channel 122 to lift the moving rod 111, and then the moving rod 111 lifts the cylinder gasket 200 through the side rod 112.

[0025] That is to say, due to the provision of the piston chamber 105, the adjustment mechanism 150 and the movable moving rod 111, when the moving mold 102 reciprocates to stamp the cylinder gasket 200, the gas will undergo compression, storage, transportation and other processes in the piston chamber 105, and the power of gas compression is used to drive the moving rod 111 to move upward, so that the moving rod 111 lifts the cylinder gasket 200 after stamping, thereby increasing the speed of the staff's removal, reducing the staff's stay time under the moving mold 102, and improving the safety of material removal.

[0026] like Figure 4 and Figure 5As shown, the top of the slide groove 120 passes through the fixed mold 103, and the top of the fixed mold 103 is provided with a groove for accommodating the side rod 112. Under normal circumstances, the side rod 112 is located in the groove to avoid affecting the placement of the cylinder gasket 200; in addition, a gap for gas discharge is reserved between the outer ring at the bottom end of the moving rod 111 and the side wall of the slide groove 120, and a reset spring 121 is provided between the bottom end of the moving rod 111 and the bottom of the slide groove 120 to elastically connect the two, which is used to drive the moving rod 111 to move downward and reset after moving upward.

[0027] like Figure 6 As shown, an upper partition 131 and a lower partition 130 are fixedly arranged in the piston chamber 105 from top to bottom. The upper partition 131 divides the upper half of the piston chamber 105 into a boost chamber 132, and the lower partition 130 divides the lower half of the piston chamber 105 into an air storage chamber 133. An air intake chamber 134 is formed between the upper partition 131 and the lower partition 130. An air intake passage 137 and an air exhaust passage 138 are provided on the side wall of the fixed mold 103. The air intake passage 137 is connected to the air intake chamber 134, and the air exhaust passage 138 is connected to the air storage chamber 133. The air delivery passage 122 is connected to the side wall of the air storage chamber 133. Figure 7 In the figure, a connecting pipe 135 is provided between the upper partition plate 131 and the lower partition plate 130 to connect the boost chamber 132 and the gas storage chamber 133, and a one-way air intake valve 136 is provided in the connecting pipe 135 to allow the gas in the boost chamber 132 to flow into the gas storage chamber 133.

[0028] like Figure 8 As shown, a spacer 142 is fixedly provided at the top of the lower partition 130; the adjustment mechanism 150 includes a rotating shaft 151 that rotates through the lower partition 130 in a longitudinal manner, and the rotating shaft 151 is located on the side of the spacer 142 away from the connecting pipe 135; the top end of the rotating shaft 151 is located in the air inlet chamber 134, and the bottom end is located in the air storage chamber 133; a first rotating plate 153 is fixedly provided at the top end of the rotating shaft 151, and a rotating ring 152 is fixedly provided at the bottom end, and a connecting member that elastically connects the first rotating plate 153 and the spacer 142 is provided between one side of the first rotating plate 153 and one side of the spacer 142. The connecting spring 154 is used to drive the first rotating plate 153 to reset after rotation. A first stopper 155 is provided at one end of the first rotating plate 153. The first stopper 155 is fixedly provided on the side wall of the air inlet chamber 134, and the side of the first stopper 155 close to the first rotating plate 153 is in contact with the end of the first rotating plate 153. A first air intake hole 140 is provided at the top of the upper partition 131. A first one-way valve 141 is provided in the first air intake hole 140 for allowing the gas in the air inlet chamber 134 to flow into the boost chamber 132. Fig.10 As shown, the first stopper 155 is located below the connection between the air inlet 137 and the air inlet cavity 134 , the first rotating plate 153 is inclined downward toward the air inlet 137 , and the first air intake hole 140 is located on the side of the first rotating plate 153 away from the air inlet 137 .

[0029] like Fig. 9 As shown, the outer ring of the rotating ring 152 is fitted with the inner ring of the gas storage chamber 133 to block the connection between the gas delivery channel 122 and the gas storage chamber 133; the gas delivery hole includes a first exhaust hole 156 and a first air leakage hole 157 which are arranged through the outer ring of the rotating ring 152. Fig.11 As shown, under normal conditions, the first exhaust hole 156 is misaligned with one of the air supply channels 122 , and the first leak hole 157 is misaligned with the other air supply channel 122 ; when the swivel 152 rotates, the swivel 152 is connected to one of the first exhaust holes 156 , and the first leak hole 157 is connected to the other air supply channel 122 .

[0030] Working principle: When the movable mold 102 moves downward, the piston 104 at the bottom of the movable mold 102 will also move downward with the movable mold 102, thereby entering the boosting chamber 132. When the piston 104 enters the boosting chamber 132, as the distance between the piston 104 and the top of the upper partition 131 becomes closer, the gas between the piston 104 and the upper partition 131 is pushed into the connecting pipe 135, and then enters the gas storage chamber 133 through the one-way air inlet valve 136. At this time, since the side wall of the boosting chamber 132 blocks the gas delivery channel 122, the gas in the gas storage chamber 133 cannot enter the gas delivery channel 122, resulting in a part of the gas being compressed only in the gas storage chamber 133, and the other part of the gas being directly discharged to the outside through the exhaust channel 138.

[0031] When the movable mold 102 completes the stamping of the cylinder gasket 200 and then moves upward, the movable mold 102 drives the piston 104 to move upward. During the upward movement of the piston 104, the distance between the piston 104 and the top of the upper partition 131 becomes farther, resulting in a larger space. At this time, negative pressure is generated between the bottom of the piston 104 and the upper partition 131. Fig.10 As shown, since the air inlet duct 137 is connected with the air inlet chamber 134, and the air inlet chamber 134 is connected with the boost chamber 132 through the first air intake hole 140, the external gas will be sucked into the air inlet duct 137, and then pushed by the first rotating plate 153, so that the first rotating plate 153 drives the rotating shaft 151 to rotate toward the first air intake hole 140. After the first rotating plate 153 rotates, it disengages from the first stop block 155. At this time, a gap is generated between the end of the first rotating plate 153 and the side wall of the first stop block 155, and the gas enters the first air intake hole 140 through the gap, and then enters the boost chamber 132 through the first one-way valve 141.

[0032] like Fig.11As shown, when the first rotating plate 153 drives the rotating shaft 151 to rotate toward the first air suction hole 140, the rotating shaft 151 also drives the rotating ring 152 to rotate, and the rotating ring 152 rotates to drive the first exhaust hole 156 and the first air leakage hole 157 to rotate. At this time, the first exhaust hole 156 is connected to one of the air supply channels 122, and the first air leakage hole 157 is connected to the other air supply channel 122. Then, the compressed gas in the gas storage chamber 133 enters the chute 120 through the air supply channel 122, and the flow rate of the gas entering the chute 120 is greater than the flow rate of the gas flowing out through the gap between the moving rod 111 and the chute 120. Therefore, under the action of the compressed gas, the gas pushes the moving rod 111 to move the moving rod 111 upward, and the moving rod 111 moves upward to drive the side rod 112, and the side rod 112 moves upward to drive the cylinder pad 200 upward. At this time, the cylinder pad 200 is separated from the top of the fixed mold 103, and the staff can easily remove the cylinder pad 200.

[0033] It should be noted that when the gas in the boost chamber 132 enters the gas storage chamber 133, part of the gas in the gas storage chamber 133 will be discharged through the exhaust passage 138. Therefore, the exhaust speed of the exhaust passage 138 is less than the speed of the piston 104 completing a single reciprocating motion. That is, when the piston 104 moves down to the boost chamber 132, the gas in the boost chamber 132 enters the gas storage chamber 133 and is compressed. At this time, the gas in the gas storage chamber 133 is discharged through the exhaust passage 138; when the piston 104 moves up and leaves the boost chamber 132, the exhaust passage 138 is still discharging the gas in the gas storage chamber 133. In this way, it can be ensured that when the piston 104 moves up, there is still compressed gas in the gas storage chamber 133, thereby realizing the driving of the movable rod 111. Then, after a period of time, the compressed gas in the air storage chamber 133 is gradually emptied. At this time, the pressure in the air storage chamber 133 is consistent with the outside, and the gas in the slide groove 120 also slowly flows out through the gap between the movable rod 111 and the slide groove 120. At this time, the reset spring 121 can pull the movable rod 111 down and reset.

[0034] Moreover, the exhaust volume of the first exhaust hole 156 is greater than the exhaust volume of the first air leakage hole 157. Fig.12 As shown, due to the difference in exhaust volume between the first exhaust hole 156 and the first air leakage hole 157, the speed at which the compressed gas enters the slide groove 120 is different, and at this time, the upward movement speed of the movable rod 111 corresponding to the first exhaust hole 156 is greater than the upward movement speed of the movable rod 111 corresponding to the first air leakage hole 157. Therefore, the two movable rods 111 will have a height difference during the upward movement process, so that the heights of the two sides of the cylinder gasket 200 are different, and finally tilted, causing the cylinder gasket 200 to slide to the tilted side.

[0035] That is to say, the upward height between the two movable rods 111 on each side is adjusted by changing the exhaust volume between the first exhaust hole 156 and the first air relief hole 157, thereby forcing the cylinder gasket 200 to move upward in a tilted state, and at the same time use the inclination force to slide to one side, preventing the staff's hands from moving directly under the movable mold 102, thereby further improving the safety of taking the cylinder gasket 200.

[0036] Moreover, when the movable die 102 does not reach the maximum downward movement distance, it cannot contact the fixed die 103, and thus it is impossible to stamp the cylinder gasket 200. Figure 13-Figure 15 As shown, a second air intake hole 160 is fixedly provided at the top of the upper partition 131, and a second one-way valve 161 is provided inside the second air intake hole 160 for allowing the gas in the air intake chamber 134 to flow into the pressurizing chamber 132. A valve ball 164 that can be inserted into the second air intake hole 160 is longitudinally slidably provided below the second air intake hole 160, and a magnet block is provided at the position corresponding to the valve ball 164 at the bottom of the piston 104. When the movable mold 102 moves down to the top of the fixed mold 103, the magnet block pushes the valve ball 164 upward. Suction; a second rotating plate 162 is fixedly arranged on the top of the rotating shaft 151, a second stopper 163 is arranged at one end of the second rotating plate 162, and one end of the second rotating plate 162 is in contact with the side wall of the second stopper 163; the second stopper 163 is fixedly arranged on the side wall of the air inlet cavity 134, and a second air leakage hole 166 and a second exhaust hole 167 are arranged through the side wall of the rotating ring 152, the second air leakage hole 166 is arranged close to the first exhaust hole 156, and the second exhaust hole 167 is arranged close to the first air leakage hole 157. Fig.16 As shown, the second stopper 163 is located above the air inlet 137, the second rotating plate 162 is inclined toward the upper side of the air inlet 137, and the second air intake hole 160 is located on the side of the second rotating plate 162 away from the air inlet 137. Fig.17 As shown, the second air leakage hole 166 and the first air leakage hole 156 are respectively located on both sides of one of the air supply channels 122; the second air leakage hole 167 and the first air leakage hole 157 are respectively located on both sides of the other air supply channel 122, and the exhaust volume of the second air leakage hole 166 is smaller than the exhaust volume of the second air leakage hole 167. A through hole 168 is provided through the side wall of the first rotating plate 153.

[0037] like Fig.14 As shown, a limit frame 165 is fixedly provided at the bottom of the upper partition 131 below the second air suction hole 160 , and the valve ball 164 is longitudinally slidably provided in the limit frame 165 .

[0038] Working principle: When the movable mold 102 moves downward normally, the distance between the piston 104 and the valve ball 164 is the shortest. At this time, the magnet block located below the piston 104 sucks the valve ball 164 upward, so that the valve ball 164 seals the bottom of the second suction hole 160. Next, when the piston 104 moves upward, the negative pressure inside the boost chamber 132 sucks the valve ball 164 to the bottom of the second air intake hole 160. At this time, only the first air intake hole 140 is in an open state. Therefore, the external gas is sucked into the air inlet 137, and a part of the gas enters the first air intake hole 140 through the through hole 168, and the other part of the gas pushes the first rotating plate 153, so that the first rotating plate 153 drives the rotating shaft 151 to rotate toward the first air intake hole 140. After the first rotating plate 153 rotates, it disengages from the first stopper 155. At this time, a gap is generated between the end of the first rotating plate 153 and the side wall of the first stopper 155, and the gas enters the first air intake hole 140 through the gap, and then enters the boost chamber 132 through the first one-way valve 141. The rotating shaft 151 in this state can be understood as forward rotation.

[0039] When the movable mold 102 does not move downward enough, the distance between the piston 104 and the valve ball 164 is too far. At this time, the magnet block below the piston 104 cannot suck the valve ball 164 upward. In other words, the first suction hole 140 and the second suction hole 160 are both in an open state. Then, when the piston 104 moves upward, negative pressure is generated inside the boosting chamber 132. At this time, Fig.16 As shown, the external gas is sucked into the air inlet 137. Since the cross-sectional area of ​​the piston 104 is large, a large amount of suction will be generated during the upward movement. Since the space below the first air inlet hole 140 is connected to the air inlet 137 through the through hole 168, a part of the gas directly enters the air storage chamber 133 through the through hole 168 and the first air inlet hole 140, resulting in a small suction force on the first rotating plate 153; while the space below the second air inlet hole 160 is in a closed state, the second rotating plate 162 is subjected to a large suction force, which also results in the second The negative pressure of the space below the air intake hole 160 is greater than the negative pressure of the space below the first air intake hole 140. At this time, the second rotating plate 162 is sucked toward the second air intake hole 160, and the second rotating plate 162 drives the rotating shaft 151 to rotate toward the second air intake hole 160. When the second rotating plate 162 rotates toward the second air intake hole 160, a gap is generated between the end of the second rotating plate 162 and the side wall of the second stopper 163, and the gas enters the second air intake hole 160 through the gap, and then enters the boosting chamber 132 through the second one-way valve 161. The rotating shaft 151 in this state can be understood as reversed.

[0040] like Fig.18As shown, when the rotating shaft 151 rotates toward the second air intake hole 160, the second air leakage hole 166 is connected to one of the air supply passages 122, and the second exhaust hole 167 is connected to the other air supply passage 122. At the same time, since the exhaust volume of the second air leakage hole 166 is less than the exhaust volume of the second exhaust hole 167, the speed at which the compressed gas enters the slide groove 120 is different, and at this time, the upward movement speed of the movable rod 111 corresponding to the second air leakage hole 166 is less than the upward movement speed of the movable rod 111 corresponding to the second exhaust hole 167. Therefore, the two movable rods 111 will have a height difference during the upward movement process, so that the heights of the two sides of the cylinder gasket 200 are different, and finally tilted, and the tilting direction is opposite to the tilting direction of the above-mentioned cylinder gasket 200, so as to remind the staff.

[0041] It can be seen that by setting the first air intake hole 140 and the second air intake hole 160 to control the swivel 152 to rotate forward or reverse, the cylinder gasket 200 can be tilted in different directions when it is lifted up, so that the staff can understand the stamping state of the cylinder gasket 200 according to the tilting state, thereby reducing the occurrence of stamping errors.
