[0034] A linkage assembly 6 is provided in two numbers and is symmetrically distributed on the left and right sides of the support seat 31, and the lifting assembly 5 and the conveying assembly 4 are connected through the linkage assembly 6, and the linkage assembly 6 comprises:

[0035] A second rotating shaft 61 is rotatably arranged on the outer surface of the support seat 31, and a second chain sprocket set 63 is arranged between the outer wall of the second rotating shaft 61 and the outer wall of the first rotating shaft 42, and a ratchet wheel 62 is arranged at the end of the second rotating shaft 61;

[0036] A rectangular frame 64 can move up and down through the lifting assembly 5, a plurality of shift blocks 65 are rotatably arranged on the inner wall of the rectangular frame 64, the shift blocks 65 can be connected with the ratchet wheel 62, the inner wall of the rectangular frame 64 is provided with a plurality of limiting plates 66 which are the same in number as the shift blocks 65, and the limiting plates 66 are attached to the bottom surface of the shift blocks 65, when the rectangular frame 64 rises with the lifting assembly 5, the shift blocks 65 contact and push the ratchet wheel 62 to rotate, and the first rotating shaft 42 is driven to rotate through the second chain sprocket set 63, thereby driving the conveying assembly 4 to perform feeding and discharging operations, and in the process of descending the rectangular frame 64, the shift blocks 65 are disconnected from the ratchet wheel 62 under the action of the limiting plates 66, the ratchet wheel 62 stops rotating, and the first chain sprocket set 41 no longer acts.

[0037] A storage box 2 is located above the support base 31 near the front side. The storage box 2 has a through-structure. L-shaped mounting brackets 21 are installed on the left and right sides of the storage box 2. The L-shaped mounting brackets 21 are fixedly installed on the top of the base 1. The storage box 2 is made of sturdy metal plate with sufficient strength and rigidity to withstand the accumulation of a certain weight of material without deformation. Operators can put a large amount of material into the storage box 2 at one time, reducing the number of times to load materials and improving the efficiency of pre-production preparation.

[0038] The support base 31 has a slot 32 at the top near the middle. Side plates 33 are fixedly connected to both sides of the support base 31. Guide grooves 34 are opened on the opposite side surfaces of the two side plates 33. The slot 32 provides installation space for the lower template 71, allowing the lower template 71 to slide up and down in the slot 32 and cooperate with the upper template 54 to complete the stamping operation.

The material at the bottom of the storage box 2 is smoothly pushed onto the lower template 71 on the slot 32 of the support base 31. At the same time, the workpiece on the lower template 71 can also be pushed to the left for unloading. Meanwhile, when the push plate 44 pushes the material under the drive of the first chain sprocket group 41, the guide rods 45 on both sides of the push plate 44 slide along the guide groove 34, so that the push plate 44 can accurately push the material to the predetermined position on the lower template 71, avoiding deviations and errors in the material pushing process, and improving the accuracy and reliability of feeding.

[0040] The lifting assembly 5 includes a hydraulic cylinder 51 installed on the top of the gantry frame 11. A telescopic rod 52 is installed on the telescopic end of the hydraulic cylinder 51. The telescopic rod 52 slides through the top of the gantry frame 11 and extends downward. A horizontal plate 53 is fixedly sleeved on the outer wall of the telescopic rod 52. Connecting blocks 55 are symmetrically installed at the bottom of the horizontal plate 53. The bottoms of the two connecting blocks 55 are respectively fixedly connected to the tops of the two rectangular frames 64. An upper template 54 is installed at the bottom of the telescopic rod 52. The hydraulic cylinder 51 in the lifting assembly 5 serves as the power core of the entire hydraulic press, providing powerful and stable power output. Through the telescopic movement of the telescopic rod 52, the up and down movement of the upper template 54 is precisely controlled to realize the stamping processing action of the material. At the same time, the horizontal plate 53 and the connecting blocks 55 connect the rectangular frame 64 to the telescopic rod 52, so that the rectangular frame 64 can move synchronously with the lifting of the telescopic rod 52, thereby achieving effective cooperation with the linkage assembly 6. Without adding an additional power source, the lifting action of the hydraulic cylinder 51 drives the conveying assembly 4 to complete the automatic feeding and unloading operation.

[0041] Multiple springs 7 are installed at the bottom of the slot 32. A lower template 71 is fixedly connected between the tops of the multiple springs 7. The lower template 71 can slide up and down close to the inner wall of the slot 32. A mold core 72 is installed near the middle of the bottom of the slot 32. The mold core 72 moves through the bottom of the lower template 71. The lower template 71 and the mold core 72 are placed directly below the upper template 54. The lower template 71 can slide up and down in a specific direction within the slot 32, cooperating with the upper template 54 to complete the stamping operation.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] First, in the initial state of this device, the telescopic rod 52 is in the lower limit position through the hydraulic cylinder 51, and the rectangular frame 64 is located below the ratchet 62. When processing is required, the material to be processed is first placed in the storage box 2.

[0044] Hydraulic cylinder 51 is activated, causing telescopic rod 52 to rise, which in turn causes horizontal plate 53 and connecting block 55 to simultaneously rise rectangular frame 64. Rectangular frame 64 rises accordingly, and at this time, the lever 65 on the inner wall of rectangular frame 64 rises and contacts ratchet 62. Due to the one-way locking characteristic of ratchet 62, lever 65 pushes ratchet 62 to rotate, which in turn drives second shaft 61 to rotate. Through second chain sprocket assembly 63, first shaft 42 rotates, driving first chain sprocket assembly 41. Connecting rod 43 and push plate 44 on first chain sprocket assembly 41, guided by guide groove 34 on side plate 33, push the material at the bottom of storage box 2 onto lower template 71 on slot 32 of support base 31. Then, telescopic rod 52 drives upper template 54 to descend, pressing against the material on lower template 71. The material is stamped. During the descent, the lever 65 disengages from the ratchet 62 under the action of the limit plate 66, the ratchet 62 stops rotating, and the first chain sprocket group 41 stops moving. During the processing, the lower template 71 will fall into the groove 32. At the same time, the processing is completed with the cooperation of the mold core 72. After the processing is completed, the upper template 54 is raised as the telescopic rod 52 drives it. The workpiece is separated from the mold core 72 under the restoring force of the spring 7. At the same time, after the workpiece is separated from the mold core 72, the lever 65 contacts the ratchet 62 again, so that the push plate 44 pushes the processed workpiece to the left for unloading. Thus, the lifting action of the hydraulic press itself is used to drive the conveying component 4 through the linkage component 6 to complete the automatic feeding and unloading operation, reducing the use of motors and electric telescopic rods, reducing energy consumption and equipment costs.
