DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0022] See also Figure 1 to Figure 5 , a stamping die for stamping parts of new energy vehicles, comprising: Machine tool 1; The punching unit 2 is slidably connected to the machine tool 1, and a punch 11 is installed at the end thereof, and is used to drive the punch 11 to slide reciprocatingly up and down; The intermittent unit 3 is provided on the punching unit 2 and is used to cooperate with the punching unit 2 to realize intermittent punching of the punch 11; The blanking unit 4 is slidably connected to the inside of the punch unit 2 and the punch 11, and is used to eject the stamping part in the punch 11; A loading unit 6 is slidably connected to the surface of the machine tool 1 and is used for loading the stamping parts; The clamping unit 5 is connected to the side of the stamping unit 2 and is intermittently connected to the feeding unit 6, and is used to clamp and fix the stamping part through the feeding unit 6; The sliding unit 7 is rotatably connected to the punching unit 2 , and its end is slidably connected to the feeding unit 6 , so as to cooperate with the punching unit 2 to realize the reciprocating sliding of the feeding unit 6 on the surface of the machine tool 1 .

[0023] In an embodiment of the present invention, when stamping stamping parts for new energy vehicles, the stamping parts material is placed on the feeding unit 6, and the stamping unit 2, in cooperation with the intermittent unit 3, drives the punch 11 to first descend, intermittently stop, then rise, and then intermittently stop again. When the punch 11 drops to the lowest point, the punch 11 will stop intermittently, which increases the contact time between the punch 11 and the stamping parts material, and prevents the material from being fully formed due to the stamping time being too fast. When the punch 11 rises to the highest point, the punch 11 will stop intermittently again, thereby providing enough time for the unloading of the stamping parts and the loading of the stamping parts material. When the stamping unit 2 descends, it can drive the sliding unit 7 to descend synchronously until the sliding unit 7 contacts the feeding unit 6, and the feeding unit 6 will drive the stamping parts material to be automatically loaded with the cooperation of the sliding unit 7. After the stamping of the stamping parts material is completed, the stamping parts will be automatically ejected under the action of the unloading unit 4, which has the advantages of high safety and high degree of automation.

[0024] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the stamping unit 2 includes: A fixed frame 21 is connected to the surface of the machine tool 1, and a driving member 22 is installed on the side; The rotating frame 23 is rotatably connected to the fixed frame 21, and the end portion is connected to the output end of the driving member 22; A lifting rod 25 is slidably connected in the machine tool 1, and a sliding frame 26 is fixed at the end thereof; A slide groove 27 is provided on the surface of the slide frame 26; The rotating column 24 is fixed to the end side of the rotating frame 23 away from the driving member 22, and the end of the rotating column 24 is slidably connected in the sliding groove 27; A bottom frame 28 is fixed to the end of the lifting rod 25 away from the sliding frame 26; The punching frame 29 is connected to the side of the base frame 28 , and the punch 11 is fixed on the punching frame 29 .

[0025] In this embodiment, when stamping parts for new energy vehicles, the stamping parts material is placed on the loading unit 6, and the driving member 22 is turned on. The output end of the driving member 22 can drive the rotating frame 23 to rotate on the surface of the fixed frame 21. When the rotating frame 23 rotates, it can drive the rotating column 24 at its end to rotate synchronously. Since the rotating column 24 is slidably connected in the slide groove 27, the sliding frame 26 will drive the lifting rod 25 to slide back and forth up and down in the machine tool 1 under the action of the slide groove 27 and the rotating column 24. When the lifting rod 25 slides back and forth, it can drive the base frame 28 at its lower end to slide synchronously, so that the base frame 28 can drive the punch 11 to slide back and forth up and down through the stamping frame 29, so that the punch 11 can stamp the new energy vehicle stamping parts material.

[0026] The driving member 22 may be an electric motor or a pneumatic motor, so as to drive the rotating frame 23 to rotate stably on the surface of the fixed frame 21 .

[0027] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the intermittent unit 3 includes: The upper arc groove 31 is provided on the sliding frame 26, and both ends thereof are connected to the ends of the sliding groove 27; The lower arc groove 32 is opened on the sliding frame 26, and its two ends are connected with the two ends of the upper arc groove 31. The radius of the upper arc groove 31 and the lower arc groove 32 are equal to the length of the rotating frame 23, and the central angle corresponding to the upper arc groove 31 and the lower arc groove 32 is less than 180 degrees. The end of the rotating column 24 is slidably connected in the upper arc groove 31 and the lower arc groove 32, and the end of the rotating frame 23 away from the rotating column 24 is located at the center of the upper arc groove 31 or the lower arc groove 32.

[0028] In this embodiment, if Figure 1 and Figure 2 As shown, the slide groove 27 is divided into two sections, wherein the left section (hereinafter referred to as the left slide groove 27) is connected to the left ends of the upper arc groove 31 and the lower arc groove 32 respectively, and the right section (hereinafter referred to as the right slide groove 27) is connected to the right ends of the upper arc groove 31 and the lower arc groove 32 respectively.

[0029] After the driving member 22 is turned on, since the rotating column 24 is slidably connected in the upper arc groove 31, the lower arc groove 32 and the slide groove 27, the rotating frame 23 will first drive the rotating column 24 to slide in the upper arc groove 31. Because the end of the rotating frame 23 away from the rotating column 24 is located at the center of the upper arc groove 31, and the radius of the upper arc groove 31 is equal to the length of the rotating frame 23, the position of the sliding frame 26 will not change during the sliding of the rotating column 24 in the upper arc groove 31.

[0030] When the rotating frame 23 rotates clockwise, the rotating frame 23 will drive the rotating column 24 to slide clockwise in the upper arc groove 31. When the rotating column 24 slides out of the right end of the upper arc groove 31, the rotating column 24 will slide into the right slide groove 27. At this time, the sliding frame 26 will drive the lifting rod 25 to slide downward in the machine tool 1 under the action of the rotating column 24 and the right slide groove 27. When sliding, the lifting rod 25 can drive the stamping frame 29 to slide downward synchronously through the base frame 28, so that the stamping frame 29 can drive the punch 11 to slide downward.

[0031] When the rotating frame 23 drives the rotating column 24 to rotate to the rightmost point, the rotating column 24 slides rightward to the rightmost point in the right slide slot 27. When the rotating frame 23 continues to rotate clockwise, the rotating frame 23 drives the rotating column 24 to slide in the right slide slot 27 in the direction of the left slide slot 27, and in this process, the sliding frame 26 also drives the lifting rod 25 to slide downward in the machine tool 1 under the action of the rotating column 24 and the right slide slot 27. When sliding, the lifting rod 25 can drive the stamping frame 29 to slide downward synchronously through the bottom frame 28, so that the stamping frame 29 can drive the punch 11 to continue to slide downward until the punch 11 contacts the automobile stamping part material to achieve the stamping of the stamping part.

[0032] When the rotating column 24 slides out of the left end of the right slide groove 27, the sliding frame 26 slides downward to the lowest point, and then the rotating column 24 slides into the lower arc groove 32. When the rotating column 24 slides clockwise in the lower arc groove 32, the end of the rotating frame 23 away from the rotating column 24 is located at the center of the lower arc groove 32. At the same time, because the radius of the lower arc groove 32 is equal to the length of the rotating frame 23, the position of the sliding frame 26 will not change during the sliding of the rotating column 24 in the lower arc groove 32.

[0033] When the rotating column 24 slides out of the left end of the lower arc groove 32 clockwise, the rotating column 24 will slide into the left slide groove 27. When the rotating column 24 slides into the left slide groove 27, the sliding frame 26 will drive the lifting rod 25 to slide upward in the machine tool 1 under the action of the rotating column 24 and the left slide groove 27. When sliding, the lifting rod 25 can drive the stamping frame 29 to slide upward synchronously through the base frame 28, so that the stamping frame 29 can drive the punch 11 to slide upward.

[0034] When the rotating frame 23 drives the rotating column 24 to rotate to the leftmost point, the rotating column 24 slides to the leftmost point in the left slide groove 27. When the rotating frame 23 continues to rotate clockwise, the rotating frame 23 drives the rotating column 24 to slide in the left slide groove 27 toward the right slide groove 27, and in this process, the sliding frame 26 also drives the lifting rod 25 to slide upward in the machine tool 1 under the action of the rotating column 24 and the left slide groove 27. When the lifting rod 25 slides, it can drive the punching frame 29 to slide upward synchronously through the bottom frame 28, so that the punching frame 29 can drive the punch 11 to continue to slide upward.

[0035] When the rotating column 24 slides out of the right end of the left slide groove 27, the sliding frame 26 rises to the highest point, and then the rotating column 24 slides into the upper arc groove 31. When the rotating column 24 slides clockwise in the upper arc groove 31, the end of the rotating frame 23 away from the rotating column 24 is located at the center of the upper arc groove 31. Therefore, the position of the sliding frame 26 will not change during the sliding process of the rotating column 24 in the upper arc groove 31.

[0036] When the rotating column 24 continues to rotate clockwise, the rotating column 24 will slide to the right slide groove 27 again, and the same as the ascending working process, at this time the sliding frame 26 will descend again, and then the punch 11 can punch the stamping material again. In summary, under the joint action of the left slide groove 27, the right slide groove 27, the upper arc groove 31, the lower arc groove 32 and the rotating column 24, the sliding frame 26 will first descend, stop intermittently, then rise, and then stop intermittently again, and cycle in sequence, so the punching frame 29 will also drive the punch 11 to first descend, stop intermittently, then rise, and then stop intermittently again.

[0037] When the punch 11 drops to the lowest point, the punch 11 can punch the material of the stamping part, and the punch 11 will stop intermittently, which increases the contact time between the punch 11 and the material of the stamping part, prevents the material from being insufficiently formed due to the stamping time being too fast, and improves the stamping effect of the punch 11 on the stamping part. When the punch 11 rises to the highest point, the punch 11 will stop intermittently again, thereby providing sufficient time for the unloading of the stamping part and the loading of the stamping part material.

[0038] In one embodiment of the present invention, Figure 4 As shown, the unloading unit 4 comprises: A groove 41 is provided on the punching frame 29; The sliding groove 42 is provided on the punching frame 29 and communicates with the groove 41; The sliding mold 43 is slidably connected in the groove 41 and the sliding groove 42; The airbag groove 44 is provided on the stamping frame 29 and has an airbag 45 installed therein; The vent hole 46 is formed on the inner wall of the groove 41 and communicates with the air bag 45 .

[0039] In this embodiment, when the base frame 28 drives the punch 11 to contact the stamping part material through the stamping frame 29, the punch 11 can punch the stamping part material at this time, and the sliding mold 43 will contact the loading unit 6 through the stamping part material. The sliding mold 43 will slide upward in the sliding groove 42 under the pushing action of the loading unit 6, so that the stamping part material is formed in the sliding groove 42 under the pushing action of the loading unit 6. When the sliding mold 43 slides upward in the sliding groove 42 and the groove 41, the space in the groove 41 will be reduced, so that the gas in the groove 41 will enter the airbag 45.

[0040] When the stamping part material is formed in the sliding groove 42, the stamping frame 29 will drive the punch 11 to rise, so that the gas in the airbag 45 will enter the groove 41 through the vent 46, and then the sliding mold 43 will slide downward in the sliding groove 42 under the action of the air pressure in the groove 41, so that the stamping part formed in the sliding groove 42 will slide out of the sliding groove 42 under the push of the sliding mold 43, thereby realizing automatic unloading of the stamping part after forming.

[0041] In one embodiment of the present invention, Figure 4 As shown, the clamping unit 5 comprises: The clamping frame 51 is slidably connected to the inside of the punching frame 29, and the end thereof is connected to the inside of the punching frame 29 through an elastic member; The clamping pad 52 is installed at the end of the clamping frame 51 .

[0042] In this embodiment, the stamping frame 29 can drive the clamping frame 51 to descend synchronously when it descends. When the clamping pad 52 at the bottom of the clamping frame 51 descends to contact the loading unit 6, the clamping frame 51 will slide upward in the stamping frame 29 under the push of the loading unit 6. The clamping frame 51 can squeeze the elastic material when sliding upward in the stamping frame 29, so that the clamping frame 51 can clamp and position the loading unit 6 through the clamping pad 52 under the elastic force of the elastic material, thereby improving the stability of the loading unit 6, and further improving the stability of the stamping material on the loading unit 6 during stamping.

[0043] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the feeding unit 6 comprises: A through hole 61 is provided on the machine tool 1; The movable frame 62 is slidably connected to the surface of the machine tool 1, and the side surface is connected to the inner wall of the through hole 61 through the elastic member 63; A placement rack 64 is fixed on the moving rack 62 and has a placement groove 65 on its surface; The push rod 66 is fixed in the placement groove 65 , and the end portion is slidably connected in the sliding groove 42 .

[0044] In this embodiment, when the stamping material is loaded, the stamping material is placed in the placement groove 65. When the punch 11 punches the stamping material, the punch 11 will slide into the placement groove 65, and the push rod 66 will be engaged in the sliding groove 42, so that the stamping material will be formed in the sliding groove 42 under the push of the push rod 66. At the same time, the sliding mold 43 will slide upward in the sliding groove 42 under the push of the push rod 66, so that the airbag 45 will expand. After the stamping material is formed in the sliding groove 42, the punch 11 will rise, and at this time, the sliding mold 43 will slide downward in the sliding groove 42 under the action of the air pressure in the groove 41, so that the stamping formed in the sliding groove 42 will slide out of the sliding groove 42 under the push of the sliding mold 43, realizing the automatic unloading of the stamping after forming.

[0045] The elastic member 63 and the elastic object can both be springs or elastic rubber, which is not limited here.

[0046] In one embodiment of the present invention, Figure 1 , Figure 3 and Figure 5 As shown, the sliding unit 7 includes: The bracket 71 is connected to the side of the bottom frame 28, and has an inclined frame 72 hinged on the surface. The side of the inclined frame 72 is connected to the side of the bracket 71 through an elastic rope 75; The positioning member 74 is fixed to the side of the bracket 71 and is engaged with the tilting frame 72 to position the tilting frame 72; A driving groove 76 is provided on the surface of the moving frame 62, and the tilting frame 72 and the roller 73 are slidably connected in the driving groove 76; The base 77 is fixed on the side of the machine tool 1, and has an inclined groove 78 on its surface. A displacement sensor 771 is installed on the side of the base 77 close to the inclined groove 78; The roller 73 is mounted on the end of the tilting frame 72 and is rollingly connected to the surface of the inclined groove 78 .

[0047] In this embodiment, when the base frame 28 slides downward, the base frame 28 can drive the tilting frame 72 to slide downward synchronously through the bracket 71, so that the tilting frame 72 will drive the roller 73 at its end to slide downward until the roller 73 slides into the driving groove 76 and contacts the inclined groove 78 on the surface of the base 77. When the base frame 28 continues to slide downward, the roller 73 will roll downward on the surface of the inclined groove 78, and the tilting frame 72 will rotate clockwise on the bracket 71 under the action of the roller 73 and the inclined groove 78, and the tilting frame 72 will stretch the elastic rope 75.

[0048] When the tilting frame 72 rotates clockwise on the bracket 71, the moving frame 62 will slide on the surface of the machine tool 1 toward the through hole 61 under the push of the driving groove 76 and the tilting frame 72, and the moving frame 62 will squeeze the elastic member 63 during the sliding process. The moving frame 62 can drive the placement frame 64 to slide synchronously during the sliding process, so that the placement frame 64 can slide through the stamping material inside the placement groove 65 until the stamping material slides to the position directly below the punch 11, so that the punch 11 can punch the stamping material, thereby realizing automatic loading of the stamping material.

[0049] When the stamping of the stamping material is completed, the base frame 28 will rise, and the base frame 28 will drive the tilting frame 72 to rise through the bracket 71, so that the tilting frame 72 rises and gradually disengages from the driving groove 76, so the moving frame 62 will be pushed by the elastic force of the elastic member 63 to reset to the left on the surface of the machine tool 1, so that the moving frame 62 drives the placement frame 64 to reset to the right, so that the placement groove 65 on the surface of the placement frame 64 is no longer located directly below the punch 11, so when the stamping material is loaded, since the placement groove 65 is no longer located directly below the punch 11, the safety of the stamping material during loading is effectively improved.

[0050] A displacement sensor 771 is installed on the side of the base 77 close to the inclined groove 78. When the roller 73 rolls to the surface that is out of the inclined groove 78, the roller 73 will slide to the side of the displacement sensor 771, so that the displacement sensor 771 senses the roller 73, indicating that the stamping material on the placement groove 65 is now located directly below the punch 11, and normal stamping can be performed.

[0051] When the displacement sensor 771 does not sense the roller 73 during the stamping process, the displacement sensor 771 will control the buzzer on the machine tool 1 to sound an alarm, indicating that the stamping material on the placement slot 65 is not directly under the punch 11 at this time, reminding the operator to pay attention so that defective products can be discovered in time.

[0052] The working principle of the present invention is: when stamping stamping parts for new energy vehicles, the stamping parts material is placed on the loading unit 6, the driving part 22 is turned on, and under the joint action of the left slide 27, the right slide 27, the upper arc groove 31, the lower arc groove 32 and the rotating column 24, the stamping frame 29 will drive the punch 11 to first descend, stop intermittently, then rise, and stop intermittently again. When the punch 11 drops to the lowest point, the punch 11 punches the stamping parts material, and the punch 11 stops intermittently, which increases the contact time between the punch 11 and the stamping parts material, prevents the material from being fully formed due to the stamping time being too fast, and improves the stamping effect of the punch 11 on the stamping parts. When the punch 11 rises to the highest point, the punch 11 will stop intermittently again, thereby providing sufficient time for the unloading of the stamping parts and the loading of the stamping parts material.
