[0012] More preferably, in the stamping equipment for the aluminum alloy bumper, a plurality of movable blocks, springs three and pressure sensors are provided, and each movable block, spring three and pressure sensor is aligned with the corresponding movable plate.

[0013] More preferably, the stamping equipment of the above-mentioned aluminum alloy bumper also includes an auxiliary component, which includes a connecting block four and a spring four; each movable plate is slidably connected to a number of connecting blocks four, and the connecting block four is rotatably connected to the corresponding round rod one; a gap is formed between the round rod one and the movable plate; each connecting block four is fixedly connected to a spring four, and the spring four is fixedly connected to the corresponding movable plate.

[0020] 3. By making the round rod 1 movable, when the bumper part is supported on the round rod 1 and pushed to move downward, the round rod 1 can be automatically locked on the movable plate under the action of gravity, thereby effectively reducing the risk of the bumper part shifting. At the same time, the small piece of the flange part that rolls down is limited by the rubber ring to prevent it from shifting to the left and right, so that it can fall into the external storage box more stably and prevent it from sliding to the ground.

[0032] The contact surfaces of the connecting block 2 4 and the movable plate 5 are both set to rough surfaces, so that the rebound spring 1 7 can drive the movable plate 5 to move slowly upward.

[0033] The fixing assembly includes a round rod 201, a spring 202 and a pressure plate 203; a plurality of round rods 201 are slidably connected to the connecting block 1; each round rod 201 is fixedly connected to a spring 202, and the spring 202 is fixedly connected to the connecting block 1; a plurality of pressure plates 203 are provided under the connecting block 1, and the pressure plates 203 are fixedly connected to the corresponding round rods 201, and the bumper part 8 is fixed by the pressure plates 203; each stamping block 2 is slidably connected to the corresponding pressure plate 203.

[0034] The positioning assembly includes a connecting block three 204, a cylinder 205 and a round rod three 206; four connecting blocks three 204 are arranged on the outside of the base 3; each connecting block three 204 is bolted to a cylinder 205; the telescopic end of each cylinder 205 is fixedly connected to a round rod three 206, and the round rod three 206 is slidably connected to the corresponding connecting block three 204, and the bumper part 8 is limited and fixed by the round rod three 206.

[0035] It also includes a detection component, which includes a movable block 207, a spring three 208 and a pressure sensor 209; each connecting block two 4 is slidably connected to a movable block 207; the lower side of each movable block 207 is fixedly connected to a spring three 208, and the spring three 208 is aligned with the corresponding connecting block two 4; the upper side of each movable block 207 is fixedly connected to a pressure sensor 209.

[0036] There are six movable blocks 207 , six springs 208 and six pressure sensors 209 , and each movable block 207 , spring 208 and pressure sensor 209 is aligned with the corresponding movable plate 5 .

[0037] First, install the connecting block 1 on the external hydraulic system, and place the external storage box in front of and behind the base 3. Then, place the bumper part 8 on the base 3 manually or by an external manipulator, and make the lower side of the bumper part 8 closely contact the upper side of the base 3. At this time, the left and right positions of the bumper part 8 are positioned by the raised parts at both ends of the base 3. Then, start the cylinder 205, and the cylinder 205 drives the round rod three 206 to move toward the bumper part 8, so that the four round rods three 206 contact the bumper part 8 at the same time and limit it. At this time, the front and rear positions of the bumper part 8 are positioned by the four round rods three 206, completing the positioning operation. At this time, the bumper part 8 pushes the round rod 6 downward under the action of gravity, and the round rod 6 drives the movable plate 5 to move downward and compresses the spring 7 until the round rod 6 is flush with the upper side of the base 3. Then the external hydraulic system drives the connecting block 1 and the parts thereon to move downward, so that the pressure plate 203 and the stamping block 2 contact the flange portion 92 of the bumper part 8. The connecting block 1 drives the stamping block 2 to continue to move downward, so that the stamping block 2 stamps the flange portion 92 of the bumper part 8, and cooperates with the groove 91 to stamp out a small piece of the flange portion 92. During this process, the pressure plate 203 remains stationary, and the connecting block 1 is relative to the round rod. The second 201 moves downward and compresses the spring 202. During this process, the stamping block 2 pushes the flange 92 small piece to move downward, and the flange 92 small piece drives the movable plate 5 and the round rod 6 to move downward and compress the spring 7, that is, the flange 92 small piece is always clamped between the stamping block 2 and the round rod 6 and will not splash outward. After the stamping is completed, the external hydraulic system drives the connecting block 1 and the parts thereon to move upward to their original position, so that the stamping block 2 stops squeezing the flange 92 small piece. At this time, the spring 7 rebounds and drives the movable plate 5 and the round rod 6 to move upward back to their original position. Since the height of the round rod 6 is set in a decreasing manner , and the round rod 16 near the middle of the base 3 is higher, so that the small pieces of the flange part 92 roll obliquely forward or backward from the round rod 16 to the external storage box, automatically completing the scrap collection operation. When in use, the stamping block 2, the movable plate 5, the round rod 16 and the spring 17 cooperate to clamp and fix the small pieces of the flange part 92 produced by the stamping, thereby avoiding many problems caused by its splashing outward. At the same time, the initial height position of the round rod 16 is set to be decreasing, so that after the stamping is completed, the small pieces of the flange part 92 can roll along the round rod 16 to the external storage box, automatically completing the scrap collection operation, which is conducive to improving efficiency.

[0038] When the pressing is completed, if the spring 17 rebounds and drives the movable plate 5 and the round rod 16 to move too fast, the round rod 16 will push the small pieces of the flange 92 away, thereby increasing the difficulty of collection. Therefore, after the pressing is completed, the external hydraulic system drives the connecting block 1 and the parts thereon to move upward to their original position, so that the stamping block 2 stops squeezing the small pieces of the flange 92. At this time, the spring 17 rebounds and drives the movable plate 5 and the round rod 16 to move upward back to their original position. Since the contact surface between the movable plate 5 and the base 3 is a friction surface, the movable plate 5 can move upward slowly, thereby causing the round rod 16 to move upward slowly, and the round rod 16 drives the small pieces of the flange 92 to tilt slowly, and then the small pieces of the flange 92 roll along the round rod 16 into the external storage box. When in use, by setting the contact surface between the base 3 and the movable plate 5 to a friction surface, the round rod 16 can move upward slowly, thereby avoiding the problem of the round rod 16 pushing the small pieces of the flange 92 away, thereby avoiding increasing the difficulty of collecting scraps.

[0039] When the bumper part 8 is placed on the base 3, if the bumper part 8 is not aligned with the base 3 in the left and right directions, the two ends of the bumper part 8 are suspended at the two ends of the base 3, and a gap will be formed between the middle of the bumper part 8 and the middle of the base 3. If the stamping operation is performed directly at this time, it will cause the problem of incorrect stamping position. Therefore, a pressure sensor 209 is set under the movable plate 5. After the bumper part 8 is placed on the base 3, the bumper part 8 pushes the round rod 6 to move downward, and the round rod 6 drives the movable plate 5 to move downward. If the movable plate 5 moves downward, it can contact the pressure sensor 209 and squeeze it, so that the pressure sensor 209 reads the pressure value, which means that the movement distance of the movable plate 5 reaches the rated value, thereby indicating that the middle of the bumper part 8 is in close contact with the middle of the base 3, that is, the bumper part 8 is in an aligned state with the base 3, and the stamping operation can be performed normally. If the movable plate 5 moves downward without contacting The pressure sensor 209 does not read the pressure value, which means that the movement distance of the movable plate 5 is less than the rated value, thereby indicating that a gap is formed between the middle of the bumper part 8 and the middle of the base 3, that is, the bumper part 8 and the base 3 are in a deviated state. At this time, the position of the bumper part 8 should be adjusted manually or by an external robotic arm before the stamping operation can be continued. During the stamping process, the stamping block 2 drives the small piece of the flange part 92 to move downward, and the small piece of the flange part 92 drives the movable plate 5 and the round rod 6 to move downward. The movable plate 5 pushes the pressure sensor 209 to move downward, and the pressure sensor 209 drives the movable block 207 to move downward and compresses the spring three 208. When in use, the position of the bumper part 8 can be detected by cooperating with the movable plate 5, the round rod 6 and the pressure sensor 209, thereby avoiding affecting the stamping operation due to the position offset of the bumper part 8 and the base 3.

[0040] During the detection process, if the bumper part 8 is a defective part and its flange part 92 is in a warped and deformed state, it will cause a misjudgment of the position detection. Therefore, the number of pressure sensors 209 is increased to six, and each pressure sensor 209 is set under the corresponding movable plate 5. After the bumper part 8 is placed on the base 3, if the bumper part 8 can repeatedly squeeze all the movable plates 5 and the round rod 6 so that each pressure sensor 209 can read the pressure value, it means that the lower side of the bumper part 8 is flat and aligned with the base 3. At this time, the stamping operation can be carried out normally. If all the pressure sensors 209 do not read the pressure value, it means that the bumper part 8 is defective. The bumper part 8 deviates from the base 3. At this time, the bumper part 8 should be adjusted and then the stamping operation should be performed. If some pressure sensors 209 read pressure values, while the other part does not read pressure values, it means that the flange part 92 of the bumper part 8 is lifted and deformed. At this time, the bumper part 8 should be taken out and the stamping operation should be stopped. When in use, the number of pressure sensors 209 is increased to six, and each pressure sensor 209 is set under the corresponding movable plate 5, so that the position offset and deformation of the bumper part 8 can be detected, effectively avoiding the problem of misdetection, thereby avoiding interference with the stamping operation.

[0041] Example 2, based on Example 1, Figure 7 As shown, an auxiliary component is also included, which includes a connecting block four 2010 and a spring four 2011; each movable plate 5 is slidably connected to two connecting blocks four 2010, and the connecting blocks four 2010 are rotatably connected to the corresponding round rod one 6; a gap is formed between the round rod one 6 and the movable plate 5; when the round rod one 6 is subjected to an extrusion force, it will drive the connecting block four 2010 to move downward and compress the spring four 2011; each connecting block four 2010 is fixedly connected to a spring four 2011, and the spring four 2011 is fixedly connected to the corresponding movable plate 5.

[0042] each round rod 6 are fixed with ten rubber rings 2012, the round rod 6 is pressed against the movable plate 5, the friction between the rubber ring 2012 and the movable plate 5 improves the fixing effect of the round rod 6.

[0043] The contact surfaces of the punching block 2 and the pressing plate 203 are both configured as smooth surfaces to reduce friction.

[0044] The connecting block 1, the punching block 2 and the base 3 are all made of rust-proof materials for rust prevention.

[0045] When the bumper member 8 is placed on the base 3, the bumper member 8 contacts the rollable round rod 16 first, thereby increasing the risk of the bumper member 8 being offset. Therefore, the round rod 16 is movably provided. When the bumper member 8 contacts the round rod 16, the round rod 16 is subjected to pressure to drive the connecting block 4 2010 to move downward, so that the connecting block 4 2010 compresses the light spring 4 2011, so that the round rod 16 contacts the movable plate 5, and friction is generated between the movable plate 5 and the round rod 16, thereby locking the round rod 16. Tighten, and then, the bumper part 8 pushes the round rod 1 6 and the movable plate 5 to move downward together until the upper side of the round rod 1 6 is flush with the upper side of the base 3. During this process, the movable plate 5 locks the round rod 1 6 by friction, which can effectively reduce the risk of the bumper part 8 shifting. When in use, by arranging the round rod 1 6 to be movably arranged, the bumper part 8 is supported on the round rod 1 6 and pushed to move downward. The round rod 1 6 is automatically locked to the movable plate 5 by the action of gravity, thereby effectively reducing the risk of the bumper part 8 shifting.

[0046] When the round rod 16 is pressed against the movable plate 5, the round rod 16 presses the rubber ring 2012 against the movable plate 5, so that friction is generated between the rubber ring 2012 and the movable plate 5. The friction is used to assist in fixing the round rod 16, which is beneficial to improving the locking effect of the round rod 16 and further reducing the risk of the bumper 8 shifting. In addition, when the flange 92 pieces roll along the round rod 16 to the external storage box, the flange 92 pieces contact with the rubber ring 2012 and generate friction. Since the rubber ring 2012 is circumferentially distributed on the surface of the movable plate 5, it can be The rubber ring 2012 limits the small piece of the flange portion 92 that has rolled down, preventing it from deviating to the left and right, so that it can fall into the external storage box more stably and prevent it from sliding to the ground. When in use, the rubber ring 2012 is used to assist in fixing the round rod 6, which is beneficial to improve the locking effect of the round rod 6 and further reduce the risk of the bumper part 8 shifting. At the same time, the rubber ring 2012 limits the small piece of the flange portion 92 that has rolled down, preventing it from deviating to the left and right, so that it can fall into the external storage box more stably and prevent it from sliding to the ground.

Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly.
