[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Please refer to Figures 1 - 10 , as an embodiment of the present invention, the stamping and forming device for the automotive bearing end cover includes a truss 1 and a base 2 provided on the truss 1. A plate outlet bin 3 is provided on the base 2. A push plate 19 is horizontally slidably provided at the bottom of the plate outlet bin 3. The stroke of the push plate 19 sliding along the bottom of the plate outlet bin 3 is the same as the horizontal length of the bottom of the plate outlet bin 3;

[0034] The push plate 19 is connected to a discharging mechanism, and the discharging mechanism is used to drive the push plate 19 to reciprocally slide along the bottom of the plate outlet bin 3, so as to push the bearing end cover steel plate located at the bottom of the plate outlet bin 3 out of the plate outlet bin 3 and fall onto the base 2;

[0035] Above the base 2, a stamping mechanism is further provided. The stamping mechanism is used to stamp and form the bearing end cover steel plate that falls onto the base 2, and the stamping mechanism cooperates with the discharging mechanism.

[0036] In this embodiment, when the stamping mechanism starts to rise and contract upward to the middle position after stamping, it will cause the plate discharging mechanism to slowly accumulate elastic potential energy. And at the moment when it contracts to the highest position, it will drive the plate discharging mechanism to release the elastic potential energy and quickly drive the push plate 19 to push the bearing end cover steel plate at the bottom of the plate outlet bin 3 onto the base 2;

[0037] It should be noted that a horizontal groove 201 is provided on the base 2. The push plate 19 is slidably provided in the horizontal groove 201, and the upper surface of the push plate 19 is flush with the upper surface of the base 2; after the bearing end cover steel plate is pushed out of the plate outlet bin 3, it falls into the horizontal groove 201 and slides to the end of the horizontal groove 201, and is directly below the stamping mechanism.

[0038] At this time, the push plate 19 is at the bottom of the plate outlet bin 3, on the side closest to the stamping mechanism. Correspondingly, the second-to-last steel plate will fall onto the surface of the push plate 19 under the action of gravity. When the stamping mechanism presses down, it stamps the bearing end cover steel plate that has just been pushed into the transverse groove 201. After stamping, the remaining steel plate edge scraps are grabbed by a robotic arm (not shown in the figure).

[0039] Obviously, a passage for a single steel plate to pass through is formed between the transverse groove 201 and the bottom edge of the plate outlet bin 3; during the process of the discharging mechanism returning to the initial position, when the stamping mechanism rises to the middle height position, the push plate 19 starts to move away from the stamping mechanism.

[0040] In this embodiment, by setting the mutual cooperation between the discharging mechanism and the stamping mechanism, the stamping and feeding of the bearing end cover steel are completed tightly, with close cooperation and stable connection between each structure.

[0041] As a further solution of the present utility model, a transverse groove 201 is provided on the base 2, and a stamping groove 202 is provided on the transverse groove 201.

[0042] In this embodiment, the transverse groove 201 is provided on the base 2 for the placement and guiding of the bearing end cover steel plate. The bottom of the plate outlet bin 3 is connected to the top surface of the base 2. The transverse groove 201 provided on the base 2 is used to receive the steel plate that falls from the bottom of the plate outlet bin 3; when the steel plate slides to the end of the transverse groove 201, the steel plate covers the stamping groove 202; under the mutual cooperation of the stamping mechanism and the stamping groove 202, a circular end cover blank with a predetermined shape and size is sheared out.

[0043] As a further solution of the present utility model, the stamping mechanism includes a first cylinder 4 and a stamping cake 5, and the stamping cake 5 is correspondingly arranged directly above the stamping groove 202. The first cylinder 4 is fixed on one side of the plate outlet bin 3, and the output end of the first cylinder 4 is matched with the discharging mechanism.

[0044] In this embodiment, when the first cylinder 4 of the stamping mechanism is activated, it will drive the stamping cake 5 to press downwards, thereby completing the stamping of the bearing end cover steel plate at the end of the transverse groove 201.

[0045] As a further solution of the present utility model, the discharging mechanism is cooperated with the output end of the first cylinder 4 through a transmission mechanism. The transmission mechanism includes a first longitudinal rod 6 arranged at the bottom of the output end of the first cylinder 4. One end of the first longitudinal rod 6 away from the first cylinder 4 is rotatably provided with a transverse connecting rod 7. One end of the transverse connecting rod 7 away from the first longitudinal rod 6 is rotatably provided with a second longitudinal rod 8. The second longitudinal rod 8 is horizontally movably arranged on the base 2, and a movable groove 203 is formed on the base 2 for the transverse connecting rod 7 to pass through and move. The second longitudinal rod 8 is cooperated with the discharging mechanism.

[0046] In this embodiment, when the first cylinder 4 rises or falls, it will drive the first longitudinal rod 6 to move up and down. Similarly, when the first longitudinal rod 6 rises, it will drive the second longitudinal rod 8 to approach the first cylinder 4 through the transverse connecting rod 7; when it falls, it will drive the second longitudinal rod 8 to move away from the first cylinder 4 through the transverse connecting rod 7.

[0047] As a further solution of the present utility model, a rack 9 is arranged at one end of the second longitudinal rod 8 away from the transverse connecting rod 7. The second longitudinal rod 8 is horizontally movably arranged on the base 2 through the rack 9, and a corresponding sliding groove 204 is formed on the base 2. The sliding groove 204 is slidably matched with the rack 9. A slider is arranged on the side of the rack 9 and is slidably matched with the sliding groove 204. An incomplete gear 10 is rotatably arranged on the base 2, and the rack 9 is adapted to the incomplete gear 10. A belt assembly 11 is arranged on the shaft of the incomplete gear 10;

[0048] The belt assembly 11 includes a belt and a belt pulley. The belt pulley is connected to the shaft of the incomplete gear 10, and the belt pulley is connected to the discharging mechanism.

[0049] In this embodiment, when the first cylinder 4 contracts upwards, the rack 9 will move to the left as shown inside the sliding groove 204. When the output end of the first cylinder 4 reaches the middle position, the rack 9 is also in the middle position inside the sliding groove 204. When the first cylinder 4 continues to move upwards, the rack 9 continues to move to the left. At this time, as shown, the meshing of the rack 9 with the toothed part on the incomplete gear 10 will drive the incomplete gear 10 to rotate clockwise (as shown). Similarly, the incomplete gear 10 will drive the discharging mechanism to act through the belt assembly 11. Figure 1 shown to the left side. When the output end of the first cylinder 4 reaches the middle position, the rack 9 is also in the middle position inside the sliding groove 204. When the first cylinder 4 continues to move upwards, the rack 9 continues to move to the left. At this time, as shown, the meshing of the rack 9 with the toothed part on the incomplete gear 10 will drive the incomplete gear 10 to rotate clockwise (as shown). Similarly, the incomplete gear 10 will drive the discharging mechanism to act through the belt assembly 11. Figure 1 shown, the meshing of the rack 9 with the toothed part on the incomplete gear 10 will drive the incomplete gear 10 to rotate clockwise (as shown). Similarly, the incomplete gear 10 will drive the discharging mechanism to act through the belt assembly 11. Figure 1 shown) to rotate. Similarly, the incomplete gear 10 will drive the discharging mechanism to act through the belt assembly 11.

[0050] As a further solution of the present utility model, the discharging mechanism includes a crank 12, a pull rod 13 and a telescopic rod 17; the telescopic rod 17 includes a sleeve and a movable rod, a spring 18 is arranged inside the sleeve, and a rotating shaft is fixed on one side of the crank 12. The rotating shaft is rotatably arranged on the base 2, and another pulley is fixed on the rotating shaft. The belt connects the two pulleys;

[0051] The sleeve is fixed on the base 2, the movable rod is coaxially and telescopically matched with the sleeve, and one end of the movable rod extending into the sleeve abuts against one end of the spring 18, and the other end of the spring 18 abuts against the inner wall of the sleeve;

[0052] One end of the movable rod extending out of the sleeve is connected to one side of the push plate 19. The end of the pull rod 13 away from the crank 12 is rotatably connected to the push plate 19, and the other end of the pull rod 13 is rotatably connected to the eccentric position of the crank 12.

[0053] In this embodiment, when the pulley rotates, it will drive the crank 12 to rotate. The crank 12 drives the push plate 19 to slide out from the bottom of the discharging bin 3 by pulling the pull rod 13. At the same time, when the push plate 19 slides out, it will drive the movable rod to further retract into the sleeve and inwardly squeeze the spring 18 inside the sleeve, so that the discharging mechanism has elastic potential energy. When the rack 9 reaches the leftmost side ( Figure 1 left side in the figure), at this time, the rack 9 is disengaged from the toothed part on the incomplete gear 10, and the stored elastic potential energy will be instantly released at this time, so as to quickly push the steel plate at the bottom of the push plate 19 out of the discharging bin 3 above the stamping groove 202, and the incomplete gear 10 returns to the state as shown in Figure 1 the figure (that is, the right side is the toothed part). When the first cylinder 4 then presses downwards, at this time the rack 9 moves to the right (as shown in the right side of Figure 1 the figure). At this time, the first tooth on the rightmost side of the rack 9 meshes with the end tooth at the bottom of the incomplete gear 10 to drive it to deflect slightly, and the incomplete gear 10 rotates a very small angle (as shown in Figure 1 counterclockwise rotation in the figure). Accordingly, the elastic potential energy will also accumulate. When the rack 9 continues to move to the right, the end tooth at the bottom of the incomplete gear 10 is separated from the first tooth on the rightmost side of the rack 9. At this time, under the action of the reset of the elastic potential energy, the incomplete gear 10 will rotate clockwise by a very small angle to reset. Then the second tooth on the right side of the rack 9 begins to engage with the end tooth at the bottom of the incomplete gear 10, continuing to make it rotate counterclockwise by a very small angle. Similarly, under the reset action of the spring 18, when the second tooth is separated from the end tooth at the bottom of the incomplete gear 10, the above actions will be repeated. In this way, when the first cylinder 4 presses down to the middle position, the rack 9 is also in the middle position of the sliding groove 204 and will continue to move to the right. At this time, the rack 9 is completely misaligned with the incomplete gear 10, and the rack 9 continues to move to the right.

[0054] As a further solution of the utility model, a second cylinder 14 is provided on the truss 1, and a push rod 15 is rotatably provided on the output end of the second cylinder 14. The end of the push rod 15 facing away from the second cylinder 14 is rotatably connected to a tray 16, and the tray 16 is located below the base 2. A vertical circular groove 205 is provided on the base 2, and a corresponding vertical round rod is provided on the tray 16. The vertical round rod is slidably matched with the vertical circular groove 205, and a through hole corresponding to the stamping groove 202 is provided on the tray 16.

[0055] In this embodiment, when the stamping on the base 2 is completed, the second cylinder 14 will run to push the push rod 15, and the push rod 15 will push the tray 16 upward, thereby driving the vertical round rod fixed on the tray 16 upward and protruding out of the vertical circular groove 205, and the remaining steel plate residue in the horizontal groove 201 will be lifted up, and finally the remaining steel plate on the tray 16 will be grabbed by the robotic arm. The robotic arm is an application of the prior art, which is not shown in the figure and will not be described again.

[0056] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
