When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.
[0032] See also Figure 1 to Figure 13 In an embodiment of the present invention, a stamping method for processing new energy vehicle parts includes the following steps: Step 1: Use a cutting device to divide the entire plate into processing blanks of uniform size; Step 2: punching the processed blank through a punching device; Step 3: Collect stamped parts; Step 4: Perform strength testing on stamped parts using a testing device.
[0033] In another embodiment of the present invention, the punching device described in step 2 can drive the upper and lower molds to approach each other, so as to deform the blank by pressure.
[0034] In another embodiment of the present invention, the punching device in step 2 comprises a chassis 1; and a workbench 101, a support rod 102, a top plate 103 and a discharge ramp 104 fixedly mounted on the chassis 1; The workbench 101 is fixedly provided with a lower mold channel 17; a lower mold fixing seat 18 is slidably engaged in the lower mold channel 17; an extrusion plate 5 is slidably engaged in the support rod 102, and an upper mold fixing seat 501 and a ring knife 502 are fixedly provided on the extrusion plate 5; The workbench 101 is provided with a loading mechanism, which can drive the blank to move between the upper mold fixing seat 501 and the lower mold fixing seat 18; The workbench 101 is provided with a punching mechanism, which can drive the extrusion plate 5 to move closer to or away from the workbench 101 after the feeding mechanism is actuated, so as to reduce or increase the distance between the upper mold fixing seat 501 and the lower mold fixing seat 18; The workbench 101 is also provided with a material return mechanism, which includes a push plate 10 ; the push plate 10 can approach or move away from the unloading ramp 104 after the punching mechanism is actuated.
[0035] Taking the embodiment combining all the features described in the present application as an example, when in use, the cutting device cuts the sheet material into strip-shaped sheet material blanks of uniform size.
[0036] The operator places the strip-shaped sheet material on the workbench 101 and starts the punching device; the loading mechanism first drives the strip-shaped sheet material to move along the length direction, so that part of the sheet material gradually moves between the upper mold fixing seat 501 and the lower mold fixing seat 18.
[0037] Afterwards, the walking mechanism stops moving and the stamping mechanism starts moving, and the stamping mechanism drives the extrusion plate 5 to approach the workbench 101, so as to drive the upper mold fixing seat 501 to approach the lower mold fixing seat 18; the plate is extruded by the upper mold on the upper mold fixing seat 501 and the lower mold on the lower mold fixing seat 18, so that the plate can be stamped into the designed shape; and during the extrusion process, the ring knife 502 moves synchronously, and the plate is extruded and cut by the ring knife 502 and the lower mold channel 17 to cut and separate the stamped parts from the strip plate, and then the stamping mechanism will drive the extrusion plate 5 away from the workbench 101; to drive the upper mold fixing seat 501 away from the lower mold fixing seat 18, so as to facilitate the subsequent action of the material return mechanism.
[0038] When the stamping mechanism drives the extrusion plate 5 away from the workbench 101, the material return mechanism will be activated, and the push plate 10 will first approach the unloading ramp 104. During the approaching process, the push plate 10 will contact the formed parts and drive the parts to move synchronously after contact, so as to push the parts into the unloading ramp 104 to complete the unloading; then the push plate 10 will move away from the unloading ramp 104 to facilitate the stamping of the remaining part of the strip plate.
[0039] Through the alternating actions of the feeding mechanism, the stamping mechanism and the material return mechanism, the automatic stamping of the plate can be realized, which avoids the cumbersome loading and unloading process and can effectively improve the production efficiency; and the shape of the waste generated by the stamping process is relatively uniform, which effectively reduces the cost investment of waste recycling; and the production environment is relatively clean, which effectively reduces the potential danger of recycling sharp metal waste.
[0040] In another embodiment of the present invention, the stamping mechanism includes a motor 2 fixedly mounted on the top plate 103; a crankshaft 3 is fixedly mounted on the output end of the motor 2, a connecting rod 4 is rotatably mounted on the crankshaft 3; and the connecting rod 4 is rotatably connected to the extrusion plate 5.
[0041] Taking the embodiment combining all the features described in this application as an example, when in use, after the plate is placed on the workbench 101, the motor 2 is started, and the motor 2 drives the crankshaft 3 to rotate, so as to drive the extrusion plate 5 to slide back and forth on the support rod 102 through the connecting rod 4 to approach or move away from the workbench 101.
[0042] When the crankshaft 3 rotates on the upper part of the top plate 103, the material unloading mechanism and the material loading mechanism will operate to complete the material unloading and loading actions; when the crankshaft 3 rotates on the lower part of the top plate 103, the stamping mechanism will first drive the extrusion plate 5 close to the workbench 101, thereby driving the upper mold fixing seat 501 close to the lower mold fixing seat 18; the plate is extruded by the upper mold on the upper mold fixing seat 501 and the lower mold on the lower mold fixing seat 18, so that the plate can be stamped into a designed shape; and during the extrusion process, the ring knife 502 operates synchronously, and the plate is extruded and cut by the ring knife 502 and the lower mold channel 17 to cut and separate the stamped parts from the strip plate, and then the stamping mechanism will drive the extrusion plate 5 away from the workbench 101; to drive the upper mold fixing seat 501 away from the lower mold fixing seat 18, so as to facilitate the subsequent material unloading mechanism action.
[0043] Through the alternating actions of the feeding mechanism, the punching mechanism and the unloading mechanism, the automatic punching of the plate can be realized, which avoids the cumbersome loading and unloading process and can effectively improve the production efficiency; and the shape of the waste generated by the punching process is relatively uniform, which effectively reduces the cost of waste recycling; and the production environment is relatively clean, which effectively reduces the potential danger of recycling sharp metal waste. In another embodiment of the present invention, a first gear 301 is fixedly mounted on the crankshaft 3; a first rotating shaft 6, a second rotating shaft 7 and a third rotating shaft 11 are rotatably mounted on the chassis 1; a second gear 601 and a half gear 602 are fixedly mounted on the first rotating shaft 6, and the first gear 301 and the second gear 601 are meshed with each other; a first unloading pulley 701 and a unloading gear 702 capable of meshing with the half gear 602 are fixedly mounted on the second rotating shaft 7; a large traveling pulley 1101 and a traveling gear 1102 capable of meshing with the half gear 602 are fixedly mounted on the third rotating shaft 11.
[0044] Taking the embodiment combining all the features described in the present application as an example, when in use, the crankshaft 3 rotates, which drives the first gear 301 to rotate synchronously, thereby driving the second gear 601 to rotate synchronously through meshing, thereby driving the first rotating shaft 6 and the half gear 602 to rotate synchronously.
[0045] The toothed portion of the rotating half gear 602 will mesh with the unloading gear 702 and the advancing gear 1102, thereby driving the second rotating shaft 7 and the third rotating shaft 11 to rotate; and when the half gear 602 is not meshing with the unloading gear 702 and the advancing gear 1102, the stamping mechanism completes the stamping of the plate.
[0046] The rotating second shaft 7 will drive the first unloading pulley 701 to rotate, thereby driving the unloading mechanism to operate; the rotating third shaft 11 will drive the large traveling pulley 1101 to rotate, thereby driving the traveling mechanism to operate. The half gear 602 will first mesh with the unloading gear 702, and then mesh with the traveling gear 1102; in this way, when the stamping mechanism drives the extrusion plate 5 away from the workbench 101 after stamping the sheet, the unloading mechanism will first operate to perform the unloading operation, and after the unloading mechanism completes the unloading, the loading mechanism will operate during the reset of the push plate 10 to complete the loading operation.
[0047] Through the alternating actions of the feeding mechanism, the stamping mechanism and the material return mechanism, the automatic stamping of the plate can be realized, which avoids the cumbersome loading and unloading process and can effectively improve the production efficiency; and the shape of the waste generated by the stamping process is relatively uniform, which effectively reduces the cost investment of waste recycling; and the production environment is relatively clean, which effectively reduces the potential danger of recycling sharp metal waste.
[0048] In another embodiment of the present invention, the unloading mechanism also includes an unloading shaft 8 rotatably mounted on the chassis 1, and a second unloading pulley 801 is fixedly mounted on the unloading shaft 8; the first unloading pulley 701 and the second unloading pulley 801 are connected by a belt; a matching groove is provided on the unloading shaft 8; a sliding sleeve 9 fixedly connected to the push plate 10 is sleeved on the unloading shaft 8; a protruding column 901 slidably engaged with the matching groove is fixedly mounted in the sliding sleeve 9; a guide rod 1001 slidably connected to the chassis 1 is fixedly mounted on the push plate 10.
[0049] In another embodiment of the present invention, the mating groove includes a first bevel groove 802 and a second bevel groove 803; wherein one end of the first bevel groove 802 is connected to one end of the second bevel groove 803; and the other end of the second bevel groove 803 is connected to the other end of the first bevel groove 802.
[0050] Taking the embodiment combining all the features recorded in the present application as an example, when in use, the rotating first unloading pulley 701 will drive the second unloading pulley 801 to rotate through the belt, and the size of the half gear 602 is twice the size of the unloading gear 702, so that after the half gear 602 is engaged with the unloading gear 702 once, the unloading gear 702 will rotate one circle, thereby driving the unloading shaft 8 to rotate one circle.
[0051] When the unloading shaft 8 rotates, it will drive the protruding column 901 to slide in the matching groove; when the protruding column 901 slides from one end to the other end in the first inclined groove 802, the mutual extrusion between the first inclined groove 802 and the protruding column 901 can drive the sliding sleeve 9 to slide in the direction of the unloading ramp 104, thereby driving the push plate 10 to move synchronously, and the guide rod 1001 can limit the rotation of the push plate 10, so that the push plate 10 can push the stamped parts into the unloading ramp 104 to complete the material removal action. In this process, the stamping mechanism drives the extrusion plate 5 away from the workbench 101, and the bottom surface of the extrusion plate 5 passes over the top surface of the push plate 10.
[0052] When the protruding column 901 slides from one end to the other end in the second inclined groove 803, the mutual squeezing of the second inclined groove 803 and the protruding column 901 can drive the sliding sleeve 9 away from the unloading ramp 104, thereby driving the push plate 10 to move synchronously to complete the resetting. During this process, the loading mechanism will operate to drive the remaining part of the plate to move between the upper mold fixing seat 501 and the lower mold fixing seat 18 to complete the loading.
[0053] In another embodiment of the present invention, the feeding mechanism includes a bracket 15 fixedly mounted on the workbench 101; multiple groups of rollers 13 are rotatably mounted on both the workbench 101 and the bracket 15; rollers 14 are fixedly mounted on the rollers 13; a traveling shaft 12 is rotatably mounted on the chassis 1, and a small traveling pulley 1201 is fixedly mounted on the traveling shaft 12; the small traveling pulley 1201 is connected to the large traveling pulley 1101 by a belt; and the traveling shaft 12 is fixedly connected to one of the rollers 13.
[0054] Taking the embodiment combining all the features recorded in the present application as an example, when in use, the size of the large traveling pulley 1101 is larger than the size of the small traveling pulley 1201, so that the large traveling pulley 1101 rotates half a circle and can drive the small traveling pulley 1201 to rotate several circles through the belt, thereby driving the second traveling shaft 12 to rotate several circles, thereby driving the roller shaft 13 to rotate several circles, and driving the roller 14 to rotate several circles.
[0055] The rollers 14 are symmetrically arranged up and down, and the plate is located between the upper and lower groups of rollers 14 and is in close contact with the rollers 14. Therefore, when one roller 14 rotates, it can drive the plate to move between the upper mold fixing seat 501 and the lower mold fixing seat 18 through the rolling friction between the rollers 14 and the plate, thereby completing the loading action; during the movement of the plate, the remaining rollers 14 can be driven to rotate through friction to reduce the resistance to movement.
[0056] In another embodiment of the present invention, a plurality of first telescopic columns 1501 are fixedly mounted on the bracket 15; a first telescopic sleeve 1301 slidably engaged with the first telescopic column 1501 is rotatably mounted on the roller shaft 13; a clamping spring 16 is arranged in the first telescopic sleeve 1301; and both ends of the clamping spring 16 respectively contact the first telescopic column 1501 and the first telescopic sleeve 1301.
[0057] Taking the embodiment combining all the features recorded in the present application as an example, when in use, in the initial state, the elastic force of the clamping spring 16 can make the upper and lower rollers 14 conflict with each other; when the plate is placed between the rollers 14, the extrusion pressure of the plate on the upper roller 14 can make the upper roller 14 move upward a certain distance. During the movement, the first telescopic column 1501 slides inward in the first telescopic sleeve 1301 to compress the clamping spring 16. At this time, the elastic force of the clamping spring 16 increases, thereby increasing the extrusion pressure of the roller 14 on the plate, thereby preventing the plate from shifting during movement.
[0058] In another embodiment of the present invention, the bottom of the lower mold channel 17 is fixedly installed on the bottom plate 19; a second telescopic column 1901 is fixedly installed on the bottom plate 19; a second telescopic sleeve 1801 slidingly engaged with the second telescopic column 1901 is fixedly installed on the lower mold fixing seat 18; a return spring 20 is arranged in the second telescopic sleeve 1801; and both ends of the return spring 20 respectively contact the second telescopic column 1901 and the second telescopic sleeve 1801.
[0059] Taking the embodiment combining all the features described in the present application as an example, when in use, when the stamping mechanism drives the extrusion plate 5 to approach the workbench 101 , the upper mold fixing seat 501 will approach the lower mold fixing seat 18 .
[0060] When the upper mold on the upper mold fixing seat 501 collides with the plate, the upper mold will squeeze the plate to cause it to deform under force; during the deformation process, the extrusion force will act on the lower mold, thereby driving the lower mold fixing seat 18 to slide downward in the lower mold channel 17, thereby driving the second telescopic column 1901 to slide inward in the second telescopic sleeve 1801 to compress the reset spring 20; when the lower mold fixing seat 18 slides to the maximum stroke, the upper mold and the lower mold have the greatest squeezing force on the plate, so that the plate will not recover after deformation, and in this process, the ring knife 502 and the lower mold channel 17 squeeze and cut the plate against each other, thereby separating the stamped parts from the plate.
[0061] After the stamping is completed, the stamping mechanism will drive the extrusion plate 5 away from the workbench 101, thereby driving the upper mold fixing seat 501 away from the lower mold fixing seat 18. At this time, the elastic force of the reset spring 20 will drive the second telescopic column 1901 to slide outward in the second telescopic sleeve 1801, thereby driving the lower mold fixing seat 18 to reset, and during the reset process, the lower mold fixing seat 18 will drive the formed parts to move upward to completely leak out of the lower mold channel 17, so as to facilitate the subsequent material removal mechanism to perform the material removal action.
[0062] Through the alternating actions of the feeding mechanism, the stamping mechanism and the material return mechanism, the automatic stamping of the plate can be realized, which avoids the cumbersome loading and unloading process and can effectively improve the production efficiency; and the shape of the waste generated by the stamping process is relatively uniform, which effectively reduces the cost investment of waste recycling; and the production environment is relatively clean, which effectively reduces the potential danger of recycling sharp metal waste.
