A push stopper 121 is installed on the top of the push slider 12, and the side wall of the push slider 12 is connected to the placement rack 11 through a reset spring 13. A discharge baffle 14 is arranged between the two limit rods 111 close to the conveying module 2, and the discharge baffle 14 is slidably installed on the limit rod 111 in the vertical direction; The conveying module 2 includes a mounting frame 21 connected to the placement frame 11, a fixed roller 22 is rotatably mounted on the lower part of the mounting frame 21, and the fixed roller 22 is transmission-connected to the driving unit 4, and can be driven by the driving unit 4 to rotate the fixed roller 22, the highest point of the fixed roller 22 in the vertical direction is flush with the upper surface of the placement frame 11, a lifting frame 23 is slidably mounted on the upper part of the mounting frame 21 in the vertical direction, and the discharge baffle 14 is connected to the lifting frame 23 and can move up and down synchronously with the lifting frame 23, and an electric push rod 24 for driving the lifting frame 23 to move in the vertical direction is also provided on the top of the mounting frame 21, and a movable roller 25 is rotatably mounted on the bottom of the lifting frame 23, the lowest point of the movable roller 25 is flush with the lower surface of the discharge baffle 14, and the spacing between the fixed roller 22 and the movable roller 25 is equal to the thickness of the metal sheet, and the movable roller 25 is connected to the fixed roller 22 through the transmission unit 5; The stamping module 3 includes a workbench 31 connected to a side of the mounting frame 21 away from the placement frame 11, a stamping groove 311 is arranged on the workbench 31, a frame 35 is arranged above the workbench 31, a hydraulic telescopic rod 32 is installed on the frame 35, the telescopic end of the hydraulic telescopic rod 32 is connected to a mounting plate 33, a stamping die 34 is arranged at the bottom of the mounting plate 33, and a positioning unit 6 for positioning the metal sheet is arranged on the workbench 31.

[0019] In the embodiment of the present invention, when in use, batches of metal sheets are stacked in the placement rack 11, and then the driving unit 4 is started, and the pushing slider 12 is driven by the driving unit 4 to swing back and forth. In the initial state, the pushing stopper 121 abuts against the side of the metal sheet away from the conveying module 2, and the pushing slider 12 can push the bottom metal sheet to the side of the conveying module 2 through the pushing stopper 121, so that the metal sheet moves to between the fixed roller 22 and the movable roller 25, and the driving unit 4 can synchronously drive the fixed roller 22 to rotate, and the fixed roller 22 drives the movable roller 25 to rotate synchronously through the transmission unit 5, and the rotation direction of the movable roller 25 is opposite to that of the fixed roller 22, so that the metal sheet is conveyed to the stamping module 3, and because the distance between the fixed roller 22 and the movable roller 25 is equal to the thickness of the metal sheet, the deformation of the metal sheet can be corrected by the fixed roller 22 and the movable roller 25. When the metal sheet moves to the stamping module 3, the positioning unit 6 can be used to position the metal sheet, and then the hydraulic telescopic rod 32 can be controlled to extend downward. The hydraulic telescopic rod 32 can drive the stamping die 34 to move downward synchronously through the mounting plate 33, and the metal sheet can be stamped through the cooperation between the stamping die 34 and the stamping groove 311. When the stamping is completed, the hydraulic telescopic rod 32 returns to the initial position, and the mounting plate 33 can drive the relevant components in the positioning unit 6 to return to the initial position. At this time, the positioning unit 6 is no longer in contact with the processed bracket, and the bracket can be easily removed from the workbench 31.

[0020] In addition, it should be noted that in order to clearly show that the highest point of the fixed roller 22 in the vertical direction is flush with the upper surface of the placement rack 11, Figure 8 Only the cross-sectional view showing the relative positional relationship among the placement rack 11, the mounting rack 21 and the fixing roller 22 is shown, and the remaining components are not shown.

[0021] like Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, as a preferred embodiment of the present invention, the driving unit 4 includes a driving motor 41 installed on a horizontal plate 112 arranged below the placement frame 11, the output end of the driving motor 41 is connected to a driving shaft 42 (two horizontal plates 112 are symmetrically arranged at the bottom, and the two ends of the driving shaft 42 can be fixed), and an anisotropic rotating wheel 43 is sleeved on the driving shaft 42, and the anisotropic rotating wheel 43 includes a large round end 431 and a small round end 432, and the two ends of the large round end 431 and the small round end 432 are connected by a transition section 433, and a mounting shaft 44 is provided on one side of the anisotropic rotating wheel 43 (the mounting shaft 44 is installed on an auxiliary frame 113 arranged at the bottom of the horizontal plate 112), and a swing rod 45 is rotatably installed on the mounting shaft 44, and a small rotating wheel 46 abutting against the anisotropic rotating wheel 43 is provided in the middle of the swing rod 45, and a sliding shaft 47 is provided at the bottom of the pushing slider 12, and the top of the swing rod 45 is connected to the sliding shaft 47.

[0022] In the embodiment of the present invention, when in use, it is only necessary to start the driving motor 41, and the driving shaft 42 can drive the driving shaft 43 to rotate, and the driving shaft 42 can drive the opposite-sex rotating wheel 43 to rotate synchronously. When the small rotating wheel 46 abuts against the large round end 431, the swing rod 45 will be pushed and swing to the side away from the conveying module 2. The swing rod 45 can drive the pusher slider 12 to slide synchronously to the side away from the conveying module 2 through the sliding shaft 47, and pull the reset spring 13, so that the pusher block 121 is stuck at the end of the metal sheet away from the conveying module 2. As the opposite-sex rotating wheel 43 rotates, the small rotating wheel 46 will abut against the large round end 431, the transition section 433 and the small round end 432 in turn. In this process, due to the elastic restoring force of the reset spring 13, the pusher slider 12 will be pulled to the side close to the conveying module 2, thereby pushing a piece of metal sheet to between the fixed roller 22 and the movable roller 25. As the anisotropic rotating wheel 43 continues to rotate, the small rotating wheel 46 will abut against the small round end 432, the transition section 433 and the large round end 431 in turn, so that the swing rod 45 is pushed to swing again to the side away from the conveying module 2, thereby realizing the linear reciprocating movement of the pushing slider 12.

[0023] It should be additionally supplemented that a sliding groove matching the sliding shaft 47 is provided at the top of the swing rod 45 to offset the displacement difference between the swing rod 45 and the sliding shaft 47 in the vertical direction during the swinging process.

[0024] like Figure 2 As shown, as a preferred embodiment of the present invention, the fixed roller 22 is connected to the drive shaft 42 through a pulley and belt mechanism, so that the drive shaft 42 can drive the fixed roller 22 to rotate synchronously, without setting an additional drive for the conveying module 2, thereby reducing energy consumption and saving costs.

[0025] like Figure 1 and Figure 4As shown, as a preferred embodiment of the present invention, the transmission unit 5 includes a transmission shaft 51 installed on the mounting frame 21, a first transmission gear 53 is installed on the lower part of the transmission shaft 51, and a second transmission gear 54 meshing with the first transmission gear 53 is installed at the end of the fixed roller 22, a sliding sleeve 52 is slidably installed on the upper part of the transmission shaft 51, the sliding sleeve 52 and the transmission shaft 51 are matched by a sliding key, and the sliding sleeve 52 is rotatably installed on one side of the lifting frame 23, the sliding sleeve 52 is also installed with a first transmission gear 53, and the end of the movable roller 25 is provided with a second transmission gear 54 meshing with the first transmission gear 53.

[0026] In the embodiment of the present invention, when in use, through the cooperation between the second transmission gear 54 on the fixed roller 22 and the corresponding first transmission gear 53, the fixed roller 22 can drive the transmission shaft 51 to rotate, and the transmission shaft 51 can drive the sliding sleeve 52 to rotate synchronously, and the cooperation between the first transmission gear 53 on the sliding sleeve 52 and the corresponding second transmission gear 54, the sliding sleeve 52 can drive the movable roller 25 to rotate, and the rotation direction of the movable roller 25 is opposite to that of the fixed roller 22, so that the metal sheet delivered from the placement module 1 is transported to the stamping module 3 for processing through the cooperation between the fixed roller 22 and the movable roller 25.

[0027] In addition, when the lifting frame 23 moves up and down, the sliding sleeve 52 will move synchronously, thereby ensuring that the sliding sleeve 52 and the movable roller 25 always maintain a transmission connection state.

[0028] like Figure 1 , Figure 5 and Figure 6 As shown, as a preferred embodiment of the present invention, the positioning unit 6 includes a sliding frame 61 slidably installed on the frame 35 along the vertical direction, and the sliding frame 61 is connected to the lifting frame 23, and sliding seats 62 are symmetrically installed on both sides of the bottom of the sliding frame 61, and the sliding seat 62 is in an inverted T shape. A limiting clamping plate 63 is slidably installed on the bottom of the sliding seat 62 along the horizontal direction (i.e., the direction of movement of the metal sheet), and the top of the limiting clamping plate 63 is hinged with a connecting rod 64, and the end of the connecting rod 64 away from the limiting clamping plate 63 is hinged to the bottom of the mounting plate 33.

[0029] In the embodiment of the present invention, during use, the lifting frame 23 can drive the sliding frame 61 to move up and down synchronously. The sliding frame 61 can drive the limit clamping plate 63 to move up and down synchronously through the sliding seat 62, so as to clamp the limit clamping plate 63 on the metal plate and limit the metal plate through the limit clamping plate 63. At the same time, during the downward movement, the mounting plate 33 can drive the limit clamping plate 63 to slide towards the side close to the stamping groove 311 through the connecting rod 64, so as to offset the displacement amount during the stamping of the metal plate, so that the limit clamping plates 63 on both sides of the stamping groove 311 can always fix both ends of the metal plate. When the stamping is completed, the hydraulic telescopic rod 32 returns to its initial position, and the relevant components in the positioning unit 6 can be driven by the mounting plate 33 to return to their initial positions. At this time, the limit clamping plate 63 no longer contacts the processed bracket, and the bracket can be conveniently removed from the workbench 31.

[0030] In addition, a baffle is provided at one end of the workbench 31 away from the mounting frame 21 for limiting the metal plate. By further limiting the top and both sides of the metal plate through the two limit clamping plates 63, rapid positioning of the metal plate can be achieved without additional positioning operations.

[0031] As Figure 6 shown, as a preferred embodiment of the present invention, the limit clamping plate 63 is in a "冂" shape, the bottom of the top wall thereof is flush with the bottom of the movable roller 25, and the distance between its two side walls is equal to the width of the metal plate. Thus, the metal plate is limited by the limit clamping plate 63 to prevent deviation during the stamping process.

[0032] Another embodiment of the present invention provides a method for processing an automotive bracket. Based on the above automotive bracket processing device, it includes the following steps: Step 1: Stack a batch of metal plates in the placement rack 11, and then start the driving unit 4. The driving unit 4 drives the pushing slider 12 to swing reciprocally. In the initial state, the pushing stop block 121 abuts against the side of the metal plate away from the conveying module 2. The pushing slider 12 can push the lowermost metal plate towards the conveying module 2 through the pushing stop block 121, so that the metal plate moves between the fixed roller 22 and the movable roller 25; Step 2: The driving unit 4 can drive the fixed roller 22 to rotate synchronously. The fixed roller 22 drives the movable roller 25 to rotate synchronously through the transmission unit 5, and the rotation direction of the movable roller 25 is opposite to that of the fixed roller 22, so as to convey the metal plate to the stamping module 3. And since the distance between the fixed roller 22 and the movable roller 25 is equal to the thickness of the metal plate, the deformation of the metal plate can be corrected by the fixed roller 22 and the movable roller 25; Step 3, when the metal sheet moves to the stamping module 3, the positioning unit 6 can be used to position the metal sheet, and then the hydraulic telescopic rod 32 is controlled to extend downward, and the hydraulic telescopic rod 32 can drive the stamping die 34 to move downward synchronously through the mounting plate 33, and the metal sheet can be stamped through the cooperation between the stamping die 34 and the stamping groove 311. When the stamping is completed, the hydraulic telescopic rod 32 returns to the initial position, and the positioning unit 6 will also return to the initial state synchronously. At this time, the positioning unit 6 is no longer in contact with the processed bracket, and the bracket can be easily removed from the workbench 31.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
