A spring pin is arranged at the bottom of the first convex block. After rotating the push plate downward, the roller slide rail moves down into the groove at the top of the operating table, and the rotation position of the push plate is locked by the spring pin. An outer slide rail is hinged to one end of the roller slide rail close to the second convex block. The outer slide rail can rotate around the connection end of the outer slide rail and the roller slide rail and fold to the side of the operating table. By rotating the outer slide rail, the end of the outer slide rail can be aligned with the end of the roller slide rail to form a snap connection.

[0011] Further, an automatic feeding structure is provided above the operating table. The automatic feeding structure includes a storage bin and a feeding plate. A support table is provided above the operating table. The storage bin is arranged on the upper part of the support table. Both the upper and lower ends of the storage bin have openings. There is a feeding port at the top of the support table. The bottom opening of the storage bin communicates with the feeding port at the top of the support table. Multiple stamping materials are placed in the storage bin waiting for stamping. A support platform is arranged at the bottom of the feeding port in the support table. The side wall of the support platform is connected to the side wall of the lower die, and the upper surface of the support platform is on the same horizontal plane as the upper surface of the lower die. The surface of the lower die has a positioning groove, and there is a stamping groove at the bottom of the positioning groove.

The pushing block passes through the operating table and is slidably arranged in the stamping groove at the top of the operating table.

[0014] In summary, the beneficial effects of the present invention are as follows: 1. In the present invention, the hydraulic cylinder in the stamping drive structure drives the crank to rotate. The crank drives the first rod body to rotate downward, and finally the upper die presses downward on the stamping materials on the lower die. Under the lever force of the crank and the first rod body, the punching force of the hydraulic cylinder is increased, making the punching force of the hydraulic cylinder reach the maximum.

[0015] 2. When the present invention performs machining, the stamping material is placed on the lower die. According to the thickness of the stamping material, the distance between the upper die and the lower die is adjusted through the height adjustment component. During stamping, the first rod body and the second rod body can be completely vertical, so that the pressure of the hydraulic cylinder can be exerted to the maximum.

[0016] 3. By rotating the push plate in the pulley moving structure to move the roller slide rail upward to contact the bottom of the lower die, pulling the lower die outward can remove the lower die from the upper part of the operating table, and pushing the lower die in the reverse direction can install the lower die on the upper part of the operating table. This structure makes the lower die form a sliding connection with the operating table, facilitating the user to remove or install the lower die.

[0017] 4. During the stamping process, the feed plate is driven to feed through the threaded rod in the automatic feeding structure. After stamping is completed, the push block in the finished product removal structure cooperates with the feed plate to operate, so that the push block ejects the finished product from the lower die. When the feed plate feeds again, it pushes the finished product outside the lower die. The present invention does not require manual loading and unloading during the stamping process, effectively preventing the occurrence of safety accidents. Description of the Drawings

Detailed implementation manner

[0020] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0021] Embodiment: As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 shown, a new type of press for mechanical processing.

[0022] Refer to Figures 1-3As shown in the figure, the first embodiment of the present invention discloses a new type of press for mechanical processing, including a machine case 1 and a stamping assembly provided on the machine case 1. The upper part of the machine case 1 has an operating table 2. The stamping material is placed on the operating table 2 and stamped by the stamping assembly. The stamping assembly includes a lower plate 31 and an upper plate 32. A connecting column 38 extends upward from the upper part of the operating table 2. The upper plate 32 is arranged on the upper part of the connecting column 38, and the lower plate 31 is arranged below the upper plate 32. The lower plate 31 forms a sliding connection with the connecting column 38. A top die 35 is fixedly installed at the central part of the bottom of the lower plate 31. A stamping driving structure is arranged between the upper plate 32 and the lower plate 31. The stamping driving structure includes a hydraulic cylinder 33 and a connecting rod assembly. A hydraulic cylinder 33 is fixedly installed on the upper part of the upper plate 32. A crank 37 is rotatably connected to the top of the upper plate 32. One end of the crank 37 forms a rotational connection with the upper plate 32, and the other end of the crank 37 is connected to the hydraulic cylinder 33. Under the lever force of the crank 37, the pressure of the hydraulic cylinder 33 is increased. The end of the crank 37 far from the hydraulic cylinder 33 is fixedly connected with a connecting rod assembly. The connecting rod assembly includes a first rod body 34 fixedly connected to the crank 37. A second rod body 39 is hinged at the bottom of the first rod body 34. The upper end of the second rod body 39 is hinged to the first rod body 34, and the lower end of the second rod body 39 is hinged to the lower plate 31. A bottom die 36 is arranged at the bottom of the top die 35. The bottom die 36 is arranged on the upper part of the operating table 2.

[0023] A height adjustment assembly is arranged between the upper plate 32 and the connecting column 38. Since the thickness of the stamping material is different, the distance between the top die 35 and the bottom die 36 is adjusted by the height adjustment assembly during stamping. During stamping, the first rod body 34 and the top die 35 can be fully straightened, so as to fully exert the maximum pressure of the hydraulic cylinder 33. Preferably, the specific structure of the height adjustment assembly includes a motor 46. The motor 46 is arranged on the upper part of the upper plate 32. A thread is formed at the upper end of the connecting column 38. Transmission parts 48 are rotatably arranged at the four corners of the upper plate 32. The transmission parts 48 are threadedly connected to the thread at the upper end of the connecting column 38. One of the transmission parts 48 in the upper plate 32 is in transmission connection with the motor 46 through a chain 47. The multiple transmission parts 48 on the upper part of the upper plate 32 are in transmission connection through a chain 47. During use, the motor 46 drives the chain 47 to rotate, so that the upper plate 32 moves upward or downward on the thread at the top of the connecting column 38, thereby adjusting the distance between the top die 35 and the bottom die 36 according to the thickness of the stamping material.

[0024] Refer to Figure 4 and Figure 5As shown in the figure, a pulley moving structure is provided on the upper part of the operating table 2. By bringing the pulley moving structure into contact with the bottom of the lower die 36, the lower die 36 is slidably connected to the operating table 2, facilitating the disassembly or installation of the lower die 36. Preferably, the pulley moving structure includes a roller slide rail 41 provided at the bottom of the lower die 36, and a groove that is recessed at the top of the operating table 2 and penetrates through both sides. The roller slide rail 41 is disposed in the groove at the top of the operating table 2. First bumps 21 and second bumps 22 are respectively protruded outward on both sides of the operating table 2. The first bump 21 and the second bump 22 are respectively disposed at both ends of the groove at the top of the operating table 2. One end of the roller slide rail 41 forms an eccentric connection with the first bump 21, and the other end of the roller slide rail 41 forms an eccentric connection with the second bump 22. A push plate 42 is rotatably connected to the side of the first bump 21, and the push plate 42 is fixedly connected to the roller slide rail 41. By rotating the push plate 42, the roller slide rail 41 can be moved upward or downward. A linkage rod 44 is connected between both ends of the roller slide rail 41, enabling both ends of the roller slide rail 41 to move upward or downward simultaneously. A spring pin 43 is disposed at the bottom of the first bump 21. After the push plate 42 is rotated downward, the roller slide rail 41 is moved downward into the groove at the top of the operating table 2, and the rotation position of the push plate 42 is locked by the spring pin 43. An outer slide rail 45 is hinged to one end of the roller slide rail 41 near the second bump 22. The outer slide rail 45 can rotate around the connection end of the outer slide rail 45 and the roller slide rail 41 and fold to the side of the operating table 2. By rotating the outer slide rail 45, the end of the outer slide rail 45 can be aligned with the end of the roller slide rail 41 to form a snap connection. By providing the outer slide rail 45, the lower die 36 can be moved onto the outer slide rail 45, facilitating the disassembly or installation of the lower die 36.

[0025] When using the present invention for machining, the stamping material is placed on the lower die 36. According to the thickness of the stamping material, the distance between the upper die 35 and the lower die 36 is adjusted by the height adjustment assembly, so that the pressure of the hydraulic cylinder 33 can be maximized. The hydraulic cylinder 33 drives the crank 37 to rotate, and the crank 37 drives the first rod 34 to rotate downward, finally causing the upper die 35 to press downward on the stamping material on the lower die 36. Under the lever force of the crank 37 and the first rod 34, the pressure of the hydraulic cylinder 33 is increased. By rotating the push plate 42, the roller slide rail 41 is moved upward to contact the bottom of the lower die 36, and by pulling the lower die 36 outward, the lower die 36 can be removed from the upper part of the operating table 2. By pushing the lower die 36 in the reverse direction, the lower die 36 can be installed on the upper part of the operating table 2. This structure makes the lower die 36 slidably connected to the operating table 2, facilitating the user to remove or install the lower die 36.

[0026] In the second embodiment of the present invention, refer to Figures 6-7As shown in the figure, an automatic feeding structure is provided above the operation table 2. The automatic feeding structure includes a storage bin 52 and a feeding plate 54. A support platform 51 is provided above the operation table 2. The storage bin 52 is arranged on the upper part of the support platform 51. Both the upper and lower ends of the storage bin 52 have openings. There is a feeding port at the top of the support platform 51. The bottom opening of the storage bin 52 is communicated with the feeding port at the top of the support platform 51. A plurality of stamping materials are placed in the storage bin 52 waiting for stamping. A support table 53 is arranged at the bottom of the feeding port in the support platform 51. The side wall of the support table 53 is connected to the side wall of the lower die 36, and the upper surface of the support table 53 is on the same horizontal plane as the upper surface of the lower die 36. The surface of the lower die 36 has a positioning groove, and a stamping groove is at the bottom of the positioning groove. A feeding plate 54 is horizontally movably arranged between the support table 53 and the feeding port at the top of the support platform 51. The feeding plate 54 is provided with a through feeding opening. The stamping materials in the storage bin 52 move into the feeding opening on the feeding plate 54 under the action of their own gravity. A threaded rod 55 is rotatably arranged on the side of the operation table 2. The feeding plate 54 is threadedly connected with the threaded rod 55. A gear is arranged at the end of the threaded rod 55. A moving rod 56 extends downward from the bottom of the lower plate 31. A horizontal tooth is arranged at a position near the lower end of the moving rod 56. The horizontal tooth in the moving rod 56 meshes with the gear at the end of the threaded rod 55. When the lower plate 31 moves downward for stamping, the moving rod 56 drives the threaded rod 55 to rotate, so that the feeding plate 54 moves above the lower die 36, and the stamping materials on the feeding plate 54 fall onto the positioning groove on the surface of the lower die 36 for stamping.

[0027] Refer to Figure 6 As shown in the figure, a storage box 8 for collecting finished products is arranged on the side of the operation table 2. A guide plate for sliding the finished products on the lower die 36 into the storage box 8 is arranged between the storage box 8 and the lower die 36. Refer to Figure 8As shown in the figure, a finished product removal structure is provided between the lower plate 31 and the operating table 2. The finished product removal structure includes a connecting rod 62, which is fixedly connected to the bottom of the lower plate 31. The connecting rod 62 passes through the operating table 2 and extends downward. A connecting arm 65 is provided at the bottom of the operating table 2. The connecting rod 62 forms a sliding connection with the connecting arm 65. A retaining piece 64 is formed around the bottom of the connecting rod 62. A spring is provided between the retaining piece 64 and the connecting arm 65. A pushing block 61 is provided at the upper part of the connecting arm 65. The pushing block 61 passes through the operating table 2 and is slidably arranged in the stamping groove at the top of the operating table 2. When the lower plate 31 moves downward for stamping work, the lower plate 31 drives the connecting rod 62 to move downward, and the spring 63 drives the pushing block 61 to move to the bottom of the stamping groove in the lower die 36. When the lower plate 31 moves upward, under the elastic force of the spring between the connecting arm 65 and the retaining piece 64, the pushing block 61 moves upward to eject the stamping finished product in the lower die 36 upward. When the lower plate 31 performs downward stamping again, during the process of the feeding plate 54 moving toward the lower die 36, the finished product ejected by the pushing block 61 is pushed into the storage box 8 through the end of the feeding plate 54.

[0028] When the lower plate 31 moves downward for stamping in the present invention, during the movement, the lower plate 31 drives the feeding plate 54 in the automatic feeding structure to move toward the lower die 36, so as to move the stamping material in the storage box 52 onto the lower die 36 for stamping. After stamping is completed, when the lower plate 31 moves upward, it drives the pushing block 61 to move upward to eject the finished product in the lower die 36 upward. When the lower plate 31 performs downward stamping again, the finished product ejected by the pushing block 61 is pushed into the storage box 8 through the end of the feeding plate 54. Through the automatic feeding structure of the present invention, the stamping material can be automatically moved into the lower die 36 for stamping without manual feeding. And through the coordinated operation of the finished product removal structure and the automatic feeding structure, the stamped finished product can be automatically moved into the storage box 8 without manual removal of the finished product from the lower die 36. Since no manual operation is required during the stamping process, it effectively prevents the occurrence of hydraulic press injury incidents during the stamping process.
