[0035] As Figures 1 to 4As shown in the figure, this embodiment proposes a cover flipping device for an automotive stamping hydraulic press, including a support plate 1, a flipping plate 2, and a driving assembly 3. The support plate 1 stands vertically on the hydraulic press 100. The flipping plate 2 is arranged at the top of the support plate 1 and is set corresponding to the position of the material leakage opening 1001 of the hydraulic press 100. The driving assembly 3 is arranged on the hydraulic press 100 and is connected to the flipping plate 2, so as to drive the flipping plate 2 to rotate to cover or open the material leakage opening 1001 of the hydraulic press 100. In this way, by arranging the flipping plate 2 at the top of the support plate 1, the support plate 1 and the flipping plate 2 can enclose to block the material leakage opening 1001 of the hydraulic press 100, effectively avoiding potential threats to personal safety caused by the uncovered material leakage opening during the maintenance process of workers, and improving the safety of the working environment. By arranging the driving assembly 3, the flipping plate 2 can be driven by the driving assembly 3 to rotate and flip, so as to cover or open the material leakage opening 1001 of the hydraulic press 100, avoiding manually opening the flipping plate 2 by workers, greatly reducing the working intensity of the operators, and improving the production efficiency.

[0036] In this application, when the flipping plate 2 covers the material leakage opening 1001 of the hydraulic press 100, it is convenient for workers to repair and maintain the mold, etc. When the flipping plate 2 flips to expose the material leakage opening 1001 of the hydraulic press 100, it is convenient to collect the waste generated by the blanking process.

[0037] Further, please refer to Figure 1 As shown in the figure, the flipping plate 2 and the driving assembly 3 are respectively distributed on both sides of the support plate 1. A through hole is opened on the support plate 1, and the driving assembly 3 can pass through the through hole and be connected to the flipping plate 2. By setting it in this way, the platform space of the hydraulic press 100 can be effectively utilized, and the utilization efficiency of its space can be improved. Of course, in this embodiment, according to the actual situation and specific requirements, the driving assembly 3 and the flipping plate 2 can also be located on the same side of the support plate 1. For example, the driving assembly 3 can be arranged at the end of one side of the support plate 1, which is not uniquely limited here.

[0038] Further, please refer to Figure 1 As shown in the figure, the driving assembly 3 includes a base 31. The base 31 is arranged on the hydraulic press 100. A driving motor 32 is installed on the base 31. A telescopic rod 33 is provided at the movable end of the driving motor 32. The telescopic rod 33 passes through the through hole and is connected to the flipping plate 2. In this way, by driving the telescopic rod 33 to expand and contract by the driving motor 32, the telescopic rod 33 drives the flipping plate 2 to flip, so as to realize the blocking and opening of the material leakage opening 1001.

[0039] In this application, a support rod 4 is provided on one side of the turning plate 2 facing the material leakage port 1001, and the support rod 4 is hinged to the telescopic rod 33. In this way, by providing the support rod 4, on the one hand, the turning plate 2 can be effectively supported to a horizontal state; on the other hand, through the hinge connection between the telescopic rod 33 and the support rod 4, the support rod 4 can be pulled to move by the telescopic rod 33, and the turning plate 2 can be driven to rotate by the support rod 4. That is, in this application, when the turning plate 2 needs to be retracted, the telescopic rod 33 is retracted to pull the support rod 4, and the telescopic rod 33 can pull the support rod 4 through the through hole, so that the turning plate 2 rotates clockwise to realize the retraction of the turning plate 2; when the turning plate 2 needs to be opened, the telescopic rod 33 is extended, and the telescopic rod 33 drives the support rod 4 to move, which plays a role in supporting the turning plate 2 and realizes the covering of the material leakage port 1001.

[0040] Preferably, both the support plate 1 and the turning plate 2 are steel plates with a thickness of 3 mm. In this way, a weight of about 200 Kg can be effectively borne. Of course, according to the actual situation and specific requirements, the thicknesses of the support plate 1 and the turning plate 2 can also be set to 4 mm, 5 mm, 6 mm, etc., and there is no unique limitation here.

[0041] Preferably, a frustum is provided at one end of one side of the turning plate 2, a bearing is sleeved on the frustum, and a connecting block 102 is provided on the side column 101 of the hydraulic press 100, and the bearing is arranged on the side column 101. In this way, the required rotational freedom is provided for the turning plate 2 through the rotation of the bearing. Preferably, in this application, frustums are provided at both ends of one side of the turning plate 2, and bearings are sleeved on each frustum, so as to ensure the smooth rotation of the turning plate 2.

[0042] Further, please refer to Figure 2 and Figure 3 As shown, at least one guide plate 5 is provided on the hydraulic press 100, and the guide plate 5 can be used to guide the waste materials outside the range of the material leakage port 1001 of the hydraulic press 100 to fall into the material leakage port 1001. In this way, by providing the guide plate 5, the waste materials can be guided to quickly fall into the material leakage port 1001. Preferably, the number of the guide plates 5 is two, and the two guide plates 5 are respectively distributed on opposite sides of the material leakage port 1001. By providing guide plates 5 on both sides, the waste materials outside the range of the material leakage port 1001 of the hydraulic press 100 can be further guided into the material leakage port 1001.

[0043] In this application, the cross-section of the guide plate 5 is triangular. Of course, according to the actual situation and specific requirements, the cross-section of the guide plate 5 can also be set to other shapes, and there is no unique limitation here.

[0044] Further, please refer to Figure 1As shown in the figure, the turnover plate 2 includes a main board 21 and a pair of folding plates 22. The folding plates 22 are arranged corresponding to the positions of the respective guide plates 5. The main board 21 and the respective folding plates 22 are hinged by hinges 23 respectively. In the present application, the hinge 23 only enables each folding plate 22 to bend along a specified direction, that is, only enables each folding plate 22 to bend along a direction opposite to the gravity direction of the folding plate 22. In this way, when the driving motor 32 drives the telescopic rod 33 to contract, the telescopic rod 33 pulls the support rod 4 to move correspondingly. The support rod 4 drives the main board 21 to rotate clockwise towards the guide plate 5. At the same time, the main board 21 drives the folding plate 22 to rotate. When the folding plate 22 rotates to contact the guide plate 5, with the further contraction of the telescopic rod 33, through linkage, the folding plate 22 folds under the acting force of the abutting force of the guide plate 5, avoiding mutual interference between the structural members during the contraction process and being beneficial to the contraction of the main board 21; when the driving motor 3 drives the telescopic rod 33 to extend, at this time, the telescopic rod 33 can make the main board 21 rotate counterclockwise through the support rod 4. At the same time, the main board 21 drives the folding plate 22 to rotate synchronously, so that the folding plate 22 is separated from the guide plate 5. At this time, the folding plate 22 returns to the initial horizontal state under the action of the hinge 23, realizing the shielding of the material leakage port 1001.

[0045] In the present application, after the folding plate 22 contacts the guide plate 5, the folding plate 22 can be lapped on the guide plate 5, so as to jointly form a guide for the waste material to fall into the material leakage port 1001.

[0046] Preferably, the main board 21 and the respective folding plates 22 are hinged by three hinges 23 respectively, and each hinge 23 is installed on the side of the main board 21 and the folding plate facing away from the material leakage port 1001. By arranging three hinges 23, the stability of the connection between the main board 21 and the folding plate 22 is effectively ensured.

[0047] Preferably, the folding plate 22 is triangular or right trapezoidal, so that the folding plate 22 is more matched with the guide plate 5 in structure. Of course, in the present application, according to the actual situation and specific requirements, the folding plate 22 can also be set to other shapes, which is not uniquely limited here.

[0048] Further, please refer to Figure 1 As shown in the figure, the turnover device further includes a first monitor 6, and the first monitor 6 is arranged on the side column 101 of the hydraulic press 100. By arranging the first monitor 6, it is possible to monitor whether the turnover plate 2 is turned to the horizontal state. When the turnover plate is turned to the horizontal initial state, the first monitor 6 will send out a signal, and the driving motor 32 stops working, effectively ensuring that the material leakage port 1001 is shielded by the turnover plate 2.

[0049] Further, please refer to Figure 1As shown, the turning device further includes a second monitor (not shown in the drawings), and the second monitor is disposed on the side column 101 of the hydraulic press 100. By providing the second monitor, it is possible to monitor the turning of the turning plate 2 to the position of the open material leakage port 1001, that is, when the second monitor detects that the folding plate 22 and the guide plate 5 are completely overlapped, at this time, the second monitor will send a signal to drive the motor 32 to stop working, effectively ensuring that the material leakage port 1001 is opened so that the waste can fall into the material leakage port 1001.
