[0039] Working principle:

[0040] When in use, first place the frame 1 on the ground, then place the workpiece on the working plate 41 of the ejection mechanism 4, and when the workpiece is placed, start the pressure unit 2 to punch the workpiece. After the pressure unit 2 completes punching the workpiece, the staff pulls the locking mechanism 6 to release the lock on the working plate 41. When the working plate 41 is free from the obstruction of the locking mechanism 6, the workpiece on the working plate 41 can be ejected. In addition, locking mechanisms 6 are provided on both sides of the working plate 41, so the ejection direction of the workpiece can be controlled by selecting to release the locking mechanism 6 on any side. After the workpiece is ejected, the workpiece to be punched is re-fixed on the working plate 41. On, ensure that the workpiece does not slip, and then under the stamping of the pressure unit 2, the working plate 41 is forced to reset, and the limiting mechanism 5 also re-fixes the working plate 41. After the working plate 41 is pressed to reset by the pressure unit 2, the locking mechanism 6 can be reset to prepare for the next ejection work. It should be noted that before ejecting the workpiece, it is necessary to wait for the pressure unit 2 to reset before ejecting the workpiece. In addition, when the spring assembly in the ejection mechanism 4 is damaged or needs to be repaired, the opening and closing door 3 can be opened, and the handle on the sliding plate 410 can be pulled to pull the sliding plate 410 out of the frame 1, thereby pulling the ejection mechanism 4 out of the frame 1, which can facilitate the maintenance work.

[0041] When the workpiece is stamped, the locking mechanism 6 is pulled to release the lock on the working plate 41. When the top spring 44 at the bottom of the working plate 41 is compressed by the pressure unit 2, the top spring 44 is compressed, thereby accumulating elastic potential energy. After the working plate 41 is released, the top spring 44 releases the elastic potential energy, thereby pushing the working plate 41 to move upward. Because limit blocks 42 are provided on both sides of the working plate 41, and the plug column 63 in the locking mechanism 6 is inserted in the limit block 42, when the locking mechanism 6 on one side releases the lock on the limit block 42, the working plate 41 can be rotated with the limit block 42 on the other side as the center, thereby controlling the ejection direction of the working plate 41. The bottom of the working plate 41 is connected to the ejector rod 47 through a rotating block 46, and the rotation of the rotating block 46 will not interfere with the movement of the working plate 41.

[0042] An airbag 49 is provided at the bottom of the push rod 47. Therefore, when the pressure unit 2 punches the workpiece and drives the working plate 41 to move downward, the airbag 49 is squeezed synchronously, so that the airbag 49 is compressed. However, because the airbag 49 is fixed in the fixing tube 48, the deformation position of the airbag 49 is limited. After the working plate 41 is unlocked, the airbag 49 is not compressed, so it expands and resets, so as to push the push rod 47 upward, and then assist the push spring 44 to push the working plate 41 upward. When the working plate 41 is compressed by the pressure unit 2, the fixing shell 45 is used to limit the moving position of the working plate 41.

[0043] After the working plate 41 ejects the workpiece, the workpiece to be punched is placed on the working plate 41, and it is ensured that the workpiece does not slide off the working plate 41. Then, when the pressure unit 2 punches the workpiece again, it drives the working plate 41 to reset. After the working plate 41 contacts the fixed shell 45, the working plate 41 stops moving. At the same time, the top column 55 in the limiting mechanism 5 is connected to the compression spring 53 through the top plate 54. When the working plate 41 is reset, the edge of the working plate 41 contacts the top column 55 and forces the top column 55 to slide toward the fixed frame 51. During the sliding process, the top column 55 synchronously drives the top plate 54 to slide toward the limiting cylinder 52, thereby squeezing the compression spring 53 so that the compression spring 53 accumulates elastic potential energy. Therefore, when the top column 55 is in the semicircular groove 43 on the working plate 41, it is ejected and slides into the semicircular groove 43, thereby limiting the position of the working plate 41, and then assisting the locking mechanism 6 to lock the working plate 41.

[0044] After the position of the working plate 41 is limited by the limiting mechanism 5, the pull rod 61 is pulled in the direction of the opening and closing door 3, thereby driving the plug column 63 to be inserted into the limiting block 42, thereby limiting the position of the working plate 41. The fixed block 62 on the pull rod 61 is connected to the limiting rod 7, so the fixed block 62 can only slide along the limiting rod 7, thereby limiting the position of the pull rod 61 and preventing the pull rod 61 from rotating, making it inconvenient for the staff to lock the working plate 41.

[0045] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
