DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

1-4, the utility model provides a sheet metal stamping device, including a support frame 1, a lower die frame 2 is fixedly connected to the middle of the support frame 1, a lower stamping die 3 is detachably connected to the middle of the lower die frame 2, a hydraulic cylinder 4 is fixedly connected to the top wall of the support frame 1, a mounting seat 5 is fixedly connected to the telescopic end of the hydraulic cylinder 4, and an upper stamping die 6 adapted to the lower stamping die 3 is detachably connected to the bottom of the mounting seat 5; a moving seat 7 is arranged at the bottom of the support frame 1, a push rod 8 is fixedly connected to the top of the moving seat 7, the top end of the push rod 8 vertically penetrates the ejection hole of the lower stamping die 3, and the top end of the push rod 8 is not higher than the lowest plane of the top surface of the lower stamping die 3; an inclined plate 17 is fixedly connected inside the support frame 1, the highest point of the inclined plate 17 is flush with the highest surface of the lower stamping die 3, the number of the push rods 8 is four, and the length of the two push rods 8 close to the inclined plate 17 is less than the length of the remaining push rods 8; two lifting assemblies are symmetrically fixedly connected to the mounting seat 5, the lifting assemblies slide through the lower die frame 2, and the two lifting assemblies are symmetrically arranged on both sides of the moving seat 7. Since the length of the two push rods 8 close to the inclined plate 17 is shorter than that of the other push rods 8, the two push rods 8 far from the inclined plate 17 are first in contact with the metal plate, so that the metal plate is tilted relative to the inclined plate 17 when it is lifted up, so that the lifted metal plate can slide directly into the inclined plate 17 for collection. The hydraulic cylinder 4 drives the upper stamping die 6 to cooperate with the lower stamping die 3 to stamp the metal. At the same time, the mounting seat 5 will drive the lifting assembly to move downward during the downward movement, and the lifting assembly cooperates with the moving seat 7. When the stamping is completed and the mounting seat 5 moves upward, the lifting assembly drives the moving seat 5 to move upward, and the metal plate on the lower stamping die 3 is lifted up by the push rods 8, so that the metal plate can be taken out and collected.

In a specific embodiment, a sliding plate 9 is fixedly connected between the hydraulic cylinder 4 and the mounting seat 5, the sliding plate 9 is slidably connected to the support frame 1, and the two lifting assemblies are respectively fixedly connected to the sliding plate 9. The lifting assembly and the mounting seat 5 are connected through the sliding plate 9, so that the lifting assembly moves with the hydraulic cylinder 4, and no additional control system is required.

In a specific embodiment, the lifting assembly includes a moving rod 10 fixedly connected to the sliding plate 9. The moving rod 10 passes through the lower mold frame 2 and is slidably connected to the lower mold frame 2. The bottom end of the moving rod 10 is located below the lower mold frame 2. The peripheral side of the moving rod 10 located below the lower mold frame 2 is rotatably connected to a clamping plate 11 through a connecting rod. The bottom end of the clamping plate 11 is provided with a clamping protrusion. The bottom of the peripheral side of the moving seat 7 is provided with an annular clamping groove 12, and the clamping protrusion cooperates with the annular clamping groove 12. The downward movement of the moving rod 10 drives the clamping plate 11 to move downward. The clamping plate 11 contacts the side of the moving seat 7 during the downward movement, and then the clamping protrusion under the clamping plate 11 slides into the annular clamping groove 12 to achieve clamping. During the upward movement of the moving rod 10, the clamping plate 11 is used to lift the moving seat 7 to achieve the lifting function.

In a specific embodiment, the bottom end of the moving rod 10 is fixedly connected with an arc sleeve 13, and the bottom of the clamping plate 11 is fixedly connected with an arc slide bar 14 corresponding to the arc sleeve 13. The end of the arc slide bar 14 is located in the arc sleeve 13 and is slidably connected with the inner wall of the arc sleeve 13. The arc center of the arc slide bar 14 and the arc sleeve 13 coincides with the rotation center of the clamping plate 11. A pressure spring 15 is fixedly connected between the bottom of the clamping plate 11 and the bottom of the moving rod 10. The arc slide bar 14 slides in the arc sleeve 13, and under the action of the pressure spring 15, the clamping protrusion at the bottom of the clamping plate 11 is squeezed into the annular clamping groove 12 to achieve clamping.

In a specific embodiment, the bottom surface of the lower mold frame 2 is fixedly connected to the two clamping plates 11 with two blocks 16, the block 16 is located above the clamping plates 11, the cross section of the block 16 is a right triangle, and the inclined surface of the block 16 is arranged toward the moving seat 7. The clamping plate 11 contacts the block 16 during the upward movement of the moving rod 10, and rotates left and right under the block 16, thereby separating from the annular clamping groove 12 at the bottom of the moving seat 7, so that the moving seat 7 can return to its initial position.

In a specific embodiment, a return spring 18 is connected to the outer surface of the push rod 8, one end of the return spring 18 is fixedly connected to the top surface of the moving seat 7, and the other end of the return spring 18 abuts against the bottom surface of the lower stamping die 3. After the stopper 16 separates the clamping plate 11 from the annular clamping groove 12, the moving block 7 can fall on the support frame 1 under the combined action of its own gravity and the return spring 18 to restore the initial position, so as to facilitate the next stamping work.

The working process of the utility model is as follows: when in use, the hydraulic cylinder 4 is started, and the upper stamping die 6 is driven by the hydraulic cylinder 4 to stamp the sheet metal blank placed on the lower stamping die 3. At the same time, the hydraulic cylinder 4 drives the moving rod 10 to move downward through the sliding plate 9, and the moving rod 10 drives the clamping plate 11 to move downward. During the downward movement of the clamping plate 11, it contacts the side of the moving seat 7, and then under the action of the pressure spring 15, the clamping protrusion moves to the annular clamping groove 12 to achieve clamping. When the stamping stroke is completed, the hydraulic cylinder 4 drives the upper stamping die 6 to move upward, and at the same time drives the moving rod 10 to move upward through the sliding plate 9, so that the moving seat 7 is lifted by the clamping plate 11, and the moving seat 7 drives the ejector rod 8 to lift the metal plate in the lower stamping die 3. Since the two ejector rods 8 close to the inclined plate 17 are short rods, the lifted metal plate tilts toward the inclined plate 17, so that it falls into the inclined plate 17 for collection. As the moving rod 10 continues to rise, the clamping plate 11 contacts the block 16, and the clamping plate 11 rotates, causing the clamping protrusion to separate from the annular clamping groove 12. The moving seat 7 falls to the bottom of the support frame 1 under the combined action of gravity and the return spring 18, facilitating the next stamping work.
