Detailed Embodiment

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1. A stamping device for an aluminum alloy bumper, as Figures 1 - 6 shown, includes a connecting block 1, a stamping block 2 and a base 3; two stamping blocks 2 are fixedly connected to the connecting block 1; a base 3 is arranged below the connecting block 1; it further includes a connecting block 4, a movable plate 5, a first round rod 6, a first spring 7, a fixing component and a positioning component; two connecting blocks 4 are bolted to the base 3; three movable plates 5 are slidably connected to each connecting block 4; a first round rod 6 is rotatably connected to each movable plate 5; the heights of the first round rods 6 are arranged in a decreasing manner; the first round rod 6 near the middle of the base 3 is at a higher position; the first round rod 6 far from the middle of the base 3 is at a lower position; four first springs 7 are fixedly connected to the lower side of each movable plate 5, and the first springs 7 are fixedly connected to the corresponding connecting blocks 4; a fixing component is connected to the connecting block 1; a positioning component is arranged outside the base 3.

[0021] The contact surfaces between the connecting block 4 and the movable plate 5 are all set as rough surfaces, which can make the rebounding first spring 7 drive the movable plate 5 to move upward slowly.

[0022] The fixing component includes a second round rod 201, a second spring 202 and a pressing plate 203; several second round rods 201 are slidably connected to the connecting block 1; a second spring 202 is fixedly connected to each second round rod 201, and the second spring 202 is fixedly connected to the connecting block 1; several pressing plates 203 are arranged below the connecting block 1, and the pressing plates 203 are fixedly connected to the corresponding second round rods 201 to fix the bumper part 8 through the pressing plates 203; each stamping block 2 is slidably connected to the corresponding pressing plate 203.

[0023] The positioning component includes a connecting block 204, a cylinder 205 and a third round rod 206; four connecting blocks 204 are arranged outside the base 3; a cylinder 205 is bolted to each connecting block 204; a third round rod 206 is fixedly connected to the telescopic end of each cylinder 205, and the third round rod 206 is slidably connected to the corresponding connecting block 204 to limit and fix the bumper part 8 through the third round rod 206.

[0024] It further includes a detection component, and the detection component includes a movable block 207, a third spring 208 and a pressure sensor 209; a movable block 207 is slidably connected to each connecting block 4; a third spring 208 is fixedly connected to the lower side of each movable block 207, and the third spring 208 is aligned with the corresponding connecting block 4; a pressure sensor 209 is fixedly connected to the upper side of each movable block 207.

[0025] There are six movable blocks 207, third springs 208 and pressure sensors 209 respectively, and each movable block 207, third spring 208 and pressure sensor 209 is aligned with the corresponding movable plate 5.

[0026] First, install the first connecting block 1 on the external hydraulic system, 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 in close contact with the upper side of the base 3. At this time, position the left and right positions of the bumper part 8 through the upturned parts at both ends of the base 3. Then start the cylinder 205, and the cylinder 205 drives the third round rod 206 to move towards the bumper part 8, so that the four third round rods 206 contact the bumper part 8 simultaneously and limit it. At this time, position the front and rear positions of the bumper part 8 through the four third round rods 206 to complete the positioning operation. At this time, the bumper part 8 pushes the first round rod 6 downward under the action of gravity, the first round rod 6 drives the movable plate 5 downward, and compresses the first spring 7 until the first round rod 6 is flush with the upper side of the base 3. Then the external hydraulic system drives the first connecting block 1 and the parts thereon downward, so that the pressing plate 203 and the punching block 2 contact the flange part 92 of the bumper part 8. The first connecting block 1 drives the punching block 2 to continue moving downward, so that the punching block 2 punches the flange part 92 of the bumper part 8, and cooperates with the groove 91 to punch out small pieces of the flange part 92. During this process, the pressing plate 203 remains stationary, and the first connecting block 1 moves downward relative to the second round rod 201 and compresses the second spring 202. During this process, the punching block 2 pushes the small pieces of the flange part 92 downward, and the small pieces of the flange part 92 drive the movable plate 5 and the first round rod 6 downward, and compress the first spring 7, that is, the small pieces of the flange part 92 are always clamped between the punching block 2 and the first round rod 6 and will not splash outwards. After punching, the external hydraulic system drives the first connecting block 1 and the parts thereon to move upward to the original position, so that the punching block 2 stops squeezing the small pieces of the flange part 92. At this time, the first spring 7 rebounds and drives the movable plate 5 and the first round rod 6 to move upward to the original position. Since the height of the first round rod 6 is arranged in a decreasing manner, and the first round rod 6 closer to the middle of the base 3 has a higher height, the small pieces of the flange part 92 roll obliquely forward or backward from the first round rod 6 into the external storage box, automatically completing the operation of collecting scraps. When in use, through the cooperation of the punching block 2, the movable plate 5, the first round rod 6 and the first spring 7, the small pieces of the flange part 92 produced by punching are clamped and fixed, thus avoiding many problems caused by their outward splashing. At the same time, setting the initial height position of the first round rod 6 in a decreasing manner enables the small pieces of the flange part 92 to roll along the first round rod 6 into the external storage box after punching, automatically completing the operation of collecting scraps, which is beneficial to improving efficiency.

[0027] After stamping, if the movement speed of the movable plate 5 and the first round rod 6 driven by the spring 7 rebounds is too fast, it will cause the first round rod 6 to knock off the small flange part 92, thus increasing the collection difficulty. Therefore, after stamping, the external hydraulic system drives the first connecting block 1 and the parts thereon to move upward to the original position, so that the stamping block 2 stops squeezing the small flange part 92. At this time, the spring 7 rebounds and drives the movable plate 5 and the first round rod 6 to move upward to the 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, so that the first round rod 6 moves upward slowly. The first round rod 6 drives the small flange part 92 to tilt slowly, and then the small flange part 92 rolls along the first round rod 6 into the external storage box. When in use, by setting the contact surface between the base 3 and the movable plate 5 as a friction surface, the first round rod 6 can move upward slowly, avoiding the problem that the first round rod 6 knocks off the small flange part 92, thus avoiding increasing the collection difficulty of the scrap.

[0028] 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-right direction, the two ends of the bumper part 8 will hang on the two ends of the base 3, and there will be a gap between the middle part of the bumper part 8 and the middle part of the base 3. If stamping operation is directly carried out at this time, it will cause the problem of incorrect stamping position. Therefore, a pressure sensor 209 is arranged below the movable plate 5. After the bumper part 8 is placed on the base 3, the bumper part 8 pushes the first round rod 6 to move downward, and the first round rod 6 drives the movable plate 5 to move downward. If the movable plate 5 moves downward and can contact the pressure sensor 209 and squeeze it, so that the pressure sensor 209 reads a pressure value, it means that the movement distance of the movable plate 5 reaches the rated value, thus indicating that the middle part of the bumper part 8 is in close contact with the middle part of the base 3, that is, the bumper part 8 and the base 3 are in an aligned state, and normal stamping operation can be carried out. If the movable plate 5 moves downward without contacting the pressure sensor 209, so that the pressure sensor 209 does not read a pressure value, it means that the movement distance of the movable plate 5 is less than the rated value, thus indicating that there is a gap between the middle part of the bumper part 8 and the middle part 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 flange part 92 to move downward, the small flange part 92 drives the movable plate 5 and the first 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 third spring 208. When in use, through the cooperation of the movable plate 5, the first round rod 6 and the pressure sensor 209, the position of the bumper part 8 can be detected, avoiding the influence on the stamping operation due to the position deviation between the bumper part 8 and the base 3.

[0029] 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 misjudgment of the position detection. Therefore, six pressure sensors 209 are added, and each pressure sensor 209 is arranged below 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 first 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 deviates from the base 3. At this time, the bumper part 8 should be adjusted and then the stamping operation is carried out. If some pressure sensors 209 read the pressure value while some do not, it means that the flange part 92 of the bumper part 8 has a warped and deformed phenomenon. At this time, the bumper part 8 should be taken out and the stamping operation should be stopped. When in use, six pressure sensors 209 are added, and each pressure sensor 209 is arranged below the corresponding movable plate 5, so that the position deviation and deformation problems of the bumper part 8 can be detected, effectively avoiding the problem of misjudgment in detection, and thus avoiding interference with the stamping operation.

[0030] Embodiment 2, on the basis of Embodiment 1, as Figure 7 shown, it further includes an auxiliary component. The auxiliary component includes a fourth connecting block 2010 and a fourth spring 2011; two fourth connecting blocks 2010 are slidably connected to each movable plate 5, and the fourth connecting block 2010 is rotatably connected to the corresponding first round rod 6; a gap is formed between the first round rod 6 and the movable plate 5; after the first round rod 6 is subjected to an extrusion force, it will drive the fourth connecting block 2010 to move downward and compress the fourth spring 2011; a fourth spring 2011 is fixedly connected to each fourth connecting block 2010, and the fourth spring 2011 is fixedly connected to the corresponding movable plate 5.

[0031] It further includes a rubber ring 2012; ten rubber rings 2012 are fixedly connected to each first round rod 6. When the first round rod 6 is pressed against the movable plate 5, the fixing effect of the first round rod 6 is improved through the friction force between the rubber ring 2012 and the movable plate 5.

[0032] The contact surfaces of the stamping block 2 and the pressing plate 203 are both set as smooth surfaces to reduce friction.

[0033] The first connecting block 1, the stamping block 2 and the base 3 are all made of rust-proof materials for rust prevention.

[0034] When the bumper member 8 is placed on the base 3, the bumper member 8 preferentially contacts the rollable round rod 1, thereby increasing the risk of offset of the bumper member 8. Therefore, the round rod 1 is movably arranged. When the bumper member 8 contacts the round rod 1, the round rod 1 is driven by the pressure to drive the connecting block 4 (2010) downward, so that the connecting block 4 (2010) compresses the light spring 4 (2011), thereby enabling the round rod 1 to contact the movable plate 5, generating a frictional force between the movable plate 5 and the round rod 1, thereby locking the round rod 1. Then, the bumper member 8 pushes the round rod 1 and the movable plate 5 to move downward together until the upper side of the round rod 1 is flush with the upper side of the base 3. During this process, the movable plate 5 locks the round rod 1 through the frictional force, which can effectively reduce the risk of offset of the bumper member 8. When in use, by movably arranging the round rod 1, when the bumper member 8 is placed on the round rod 1 and pushes it downward, the round rod 1 can be automatically locked on the movable plate 5 under the action of gravity, thereby effectively reducing the risk of offset of the bumper member 8.

[0035] When the round rod 1 is pressed tightly against the movable plate 5, the round rod 1 presses the rubber ring 2012 tightly against the movable plate 5, generating a frictional force between the rubber ring 2012 and the movable plate 5, and the round rod 1 is assisted in being fixed through the frictional force, which is beneficial to improving the locking effect of the round rod 1 and further reducing the risk of offset of the bumper member 8. In addition, during the process that the small piece of the flange portion 92 rolls along the round rod 1 to the external storage box, the small piece of the flange portion 92 contacts the rubber ring 2012 and forms a frictional force. Since the rubber ring 2012 is circumferentially distributed on the surface of the movable plate 5, the rubber ring 2012 can limit the rolling small piece of the flange portion 92 to prevent it from offsetting left and right, so that it can fall more stably into the external storage box and prevent it from slipping to the ground. When in use, the rubber ring 2012 is used to assist in fixing the round rod 1, which is beneficial to improving the locking effect of the round rod 1 and further reducing the risk of offset of the bumper member 8. At the same time, the rubber ring 2012 limits the rolling small piece of the flange portion 92 to prevent it from offsetting left and right, so that it can fall more stably into the external storage box and prevent it from slipping to the ground.

[0036] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
