[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0031] Example 1

[0032] like Figure 1 and Figure 4As shown, the automatic cleaning device for stamping waste of automobile side outer panel comprises: a stamping mechanism 10, a lifting mechanism 20 and a cleaning mechanism 30, the stamping mechanism 10 comprises an upper punch 15 and a lower punch 17, the upper punch 15 is located directly above the lower punch 17, and the upper punch 15 and the lower punch 17 are respectively fixedly connected with a first driving member 14 and a support column 16 on the side away from each other, the first driving member 14 adopts a hydraulic cylinder, and the lifting mechanism 20 comprises a second driving member 21 and a lifting platform 22, the second driving member 21 adopts a hydraulic cylinder, and the output end of the second driving member 21 is fixedly connected to the lifting platform 22 Next, the lifting platform 22 is provided with a through opening 221, the size of which is adapted to the lower punch 17 so that the through opening 221 can be freely passed through the through opening 221, and the lower punch 17 is located inside the through opening 221. The cleaning mechanism 30 includes an arched platform 31, and the side wall of the arched platform 31 is rotatably connected to a swing arm 33, and one end of the swing arm 33 away from the arched platform 31 is hinged to a connecting plate 34, and the inner ring of the connecting plate 34 is movably sleeved with a first push rod 35, one end of the first push rod 35 is in contact with the outer wall of the arched platform 31, and the other end is fixedly connected to a cleaning push plate 38 in contact with the upper surface of the lifting platform 22.

[0033] The waste generated by the stamping of the upper punch 15 and the lower punch 17 will remain on the upper surface of the lifting platform 22. The second driving member 21 drives the lifting platform 22, the cleaning push plate 38, the first push rod 35 and the connecting plate 34 to rise together. The first push rod 35 pushes the cleaning push plate 38 to the side away from the arch platform 31 by cooperating with the outer wall of the arch platform 31 to clean the waste.

[0034] like Figure 4 As shown, the outer ring of the first push rod 35 is fixedly sleeved with a baffle 36, the full diameter of the baffle 36 is larger than the inner ring diameter of the connecting plate 34, so that the first push rod 35 cannot be separated from the connecting plate 34, and an elastic member 37 is fixedly connected to one side of the baffle 36, and the end of the elastic member 37 away from the baffle 36 is fixedly connected to the connecting plate 34, and the elastic member 37 is a spring.

[0035] Specifically, when an external force pushes the connecting plate 34 to rise, the end of the first push rod 35 will come into contact with the arc-shaped edge of the arch platform 31 to push the cleaning push plate 38 to move toward the side away from the arch platform 31. When the external force disappears, the connecting plate 34 will drop due to its own weight. At this time, the stress of the elastic member 37 will be released, thereby driving the cleaning push plate 38 to move toward the side close to the arch platform 31.

[0036] like Figure 4 As shown, the inner ring movable sleeve of the connecting plate 34 is provided with a second push rod 39 , one end of the second push rod 39 is in contact with the outer wall of the arched platform 31 , and the other end is fixedly connected to the cleaning push plate 38 .

[0037] The cleaning push plate 38 can only move linearly due to the restriction of the second push rod 39 , and cannot rotate around the first push rod 35 .

[0038] like Figure 4 As shown, a limiting strip 32 is fixedly connected to one side of the arched platform 31 close to the lower punch 17 , and the limiting strip 32 is located on the axis line of the arched platform 31 .

[0039] Due to the restriction of the limit bar 32 , the end of the first push rod 35 can only move to the middle point of the arc-shaped edge of the arched platform 31 . At this time, the cleaning push plate 38 has moved to the farthest point of the lifting platform 22 .

[0040] Example 2

[0041] like Figure 1 and Figure 4 As shown, this embodiment is based on the above-mentioned embodiment 1, and the sides of the two cleaning push plates 38 close to each other are fixedly connected with the second magnet 310, and the distance between the two cleaning push plates 38 is equal to or greater than the width of the through hole 221.

[0043] Specifically, when the cleaning push plate 38 drives the second magnet 310 to pass through the through-port 221, the second magnet 310 will be adsorbed together with the first magnet 24, and finally drive the sealing plate 23 to open and close. When the cleaning push plate 38 drives the second magnet 310 away from the through-port 221, the second magnet 310 will separate from the first magnet 24, and finally retain the sealing plate 23 in the through-port 221 or in the active cavity.

[0044] like Figure 1 As shown, a recovery box 18 is provided on one side of the lifting platform 22 away from the cleaning mechanism 30 for recovering waste materials, and the height of the recovery box 18 is equal to or less than the height from the support column 16 to the lower punch die 17 .

[0045] like Figure 1 As shown, the stamping mechanism 10 also includes a mounting base 11, which is fixedly connected to a mounting top plate 13 via four fixed columns 12, the four fixed columns 12 are respectively located at four corners of the mounting base 11, the support column 16, the recovery box 18 and the second driving member 21 are all fixed above the mounting base 11, the first driving member 14 is fixed in the inner circle of the mounting top plate 13, a side plate is fixedly connected between the mounting base 11 and the mounting top plate 13, and the arched platform 31 is fixed on the side plate.

[0046] The cleaning method of the automatic cleaning device for the stamping waste of the automobile side outer panel comprises the following steps:

[0047] S1, stamping: the first driving member 14 drives the upper punch 15 to approach the lower punch 17, and finally the automobile side outer panel is stamped by the cooperation of the upper punch 15 and the lower punch 17, and the waste generated by the stamping will remain on the upper surface of the lifting platform 22;

[0048] S2, waste cleaning: when the upper punch 15 is away from the lower punch 17, the lifting platform 22 is driven to rise by the second driving member 21, and the lifting platform 22 will drive the lifting platform 22, the cleaning push plate 38, the first push rod 35 and the connecting plate 34 to rise together. When the first push rod 35 rises, it will push the cleaning push plate 38 to move to the side away from the arched platform 31 through the arc wall of the arched platform 31, so as to clean the waste on the upper surface of the lifting platform 22 and push it into the interior of the recycling box 18;

[0049] S3. Preventing waste from falling: When the cleaning push plate 38 moves to the side away from the arched platform 31, the second magnet 310 fixed on the side wall of the cleaning push plate 38 will drive the sealing plate 23 to move together through the magnetic attraction with the first magnet 24, and finally close the through opening 221 to prevent waste from falling;

[0050] S4, waiting for stamping: after cleaning the waste on the upper surface of the lifting platform 22, the second driving member 21 drives the lifting platform 22 to descend. At this time, the lifting platform 22, the cleaning push plate 38, the first push rod 35 and the connecting plate 34 will also descend together due to their own gravity. At the same time, the elastic member 37 will release the stress to drive the cleaning push plate 38 to approach the arched platform 31. While driving the second magnet 310 to pass through the first magnet 24, the cleaning push plate 38 will also drive the sealing plate 23 to move together, and finally the through-hole 221 will be completely opened to facilitate the lower punch 17 to pass through the through-hole 221, waiting for the automobile side outer panel to be stamped again.
