Description

Technical Field

[0001] This invention relates to the field of forging press processing technology, and in particular to a novel press for machining. Background Technology

[0002] Presses play an important role in forging and pressing processes, and hydraulic presses are the most common type of press. Hydraulic presses have the following advantages: low manufacturing cost, good stability, high pressure, simple structure, and low maintenance cost.

[0003] However, most hydraulic presses on the market use a direct connection between the cylinder and the lower platen for pressing. This structure cannot maximize the output of the cylinder and requires manual loading and unloading, which is very dangerous. There are many hydraulic press-related injuries every year. Summary of the Invention

[0004] In order to solve the technical problems of existing technologies that cannot maximize the output of hydraulic cylinders and require manual loading and unloading, which poses safety risks, this invention provides a novel press for machining.

[0005] The present invention provides a novel press for machining, which adopts the following technical solution:

[0006] A novel press for machining includes a housing and a stamping assembly. The housing has an operating table on its upper part, and a connecting column extends upward from the upper part of the operating table. The stamping assembly is located at the upper end of the connecting column. The stamping assembly includes a lower plate and an upper die located at the bottom of the lower plate. A stamping drive structure is located between the upper plate and the lower plate. The stamping drive structure includes a hydraulic cylinder and a connecting rod assembly. Under the leverage force of the connecting rod assembly, the pressure of the hydraulic cylinder is increased. A lower die is located at the bottom of the upper die and is located on the upper part of the operating table.

[0007] The upper part of the operating table is equipped with a pulley moving structure, which has a roller slide rail that can contact the bottom of the lower mold. The lower mold and the operating table can be slidably connected through the roller slide rail. An automatic feeding structure and a finished product removal structure are located on the upper part of the operating table. The automatic feeding structure has a feeding plate for feeding. The finished product removal structure has a push block. The feeding plate and the push block work together to push the finished product out of the lower mold. The feeding plate pushes the finished product to the outside of the lower mold during feeding.

[0008] Furthermore, the upper plate is disposed above the connecting column, and the lower plate is disposed below the upper plate, with the lower plate forming a sliding connection with the connecting column.

[0009] Furthermore, the stamping drive structure includes a hydraulic cylinder and a connecting rod assembly. The hydraulic cylinder is fixedly installed on the upper part of the upper plate, and a crank is rotatably connected to the top of the upper plate. One end of the crank is rotatably connected to the upper plate, and the other end of the crank is connected to the hydraulic cylinder. Under the leverage force of the crank, the pressure of the hydraulic cylinder is increased. A connecting rod assembly is fixedly connected to the end of the crank away from the hydraulic cylinder. The connecting rod assembly includes a first rod body fixedly connected to the crank, and a second rod body hinged to the bottom of the first rod body. The upper end of the second rod body is hinged to the first rod body, and the lower end of the second rod body is hinged to the lower plate.

[0010] Furthermore, a height adjustment component is provided between the upper plate and the connecting column.

[0011] Furthermore, the specific structure of the height adjustment component includes a motor, which is located on the upper part of the upper plate. A thread is formed on the upper end of the connecting column. Transmission components are rotatably arranged at the four corners of the upper plate. The transmission components are threadedly connected to the thread on the upper end of the connecting column. One of the transmission components on the upper plate is connected to the motor by a chain. Multiple transmission components on the upper part of the upper plate are connected by a chain.

[0012] Furthermore, the pulley moving structure includes a roller slide rail disposed at the bottom of the lower mold, a recessed groove extending through both sides located at the top of the operating table, the roller slide rail being disposed within the groove at the top of the operating table, and a first protrusion and a second protrusion protruding outwards from both sides of the operating table, the first protrusion and the second protrusion being respectively disposed at both ends of the groove at the top of the operating table, one end of the roller slide rail forming an eccentric connection with the first protrusion, and the other end of the roller slide rail forming an eccentric connection with the second protrusion, the side of the first protrusion being rotatably connected to a push plate, the push plate forming a fixed connection with the roller slide rail, and the roller can be moved by rotating the push plate. The slide rail moves up or down, and a connecting rod is connected between the two ends of the roller slide rail. The connecting rod allows the two ends of the roller slide rail to move up or down simultaneously. A spring pin is provided at the bottom of the first protrusion. After the push plate is rotated downward, the roller slide rail moves down into the groove at the top of the operating table. The rotation position of the push plate is locked by the spring pin. An outer slide rail is hinged to the end of the roller slide rail near the second protrusion. The outer slide rail can rotate around the connection end between 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 locking connection.

[0013] Furthermore, an automatic feeding structure is provided on the upper part of the operating platform. This automatic feeding structure includes a storage bin and a feeding plate. A support platform is provided on the upper part of the operating platform, and the storage bin is located on the upper part of the support platform. The storage bin has openings at both the top and bottom. A feed inlet is located at the top of the support platform. The bottom opening of the storage bin is connected to the feed inlet at the top of the support platform. Multiple stamping materials are placed into the storage bin for stamping. A support platform is provided at the bottom of the feed inlet in the support platform. 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 the bottom of the positioning groove has a stamping groove. The feed inlet at the top of the support platform and the support platform... A feeding plate is laterally movable between the two parts, and a through discharge port is provided on the feeding plate. The stamping material in the storage box moves to the discharge port on the feeding plate under its own gravity. A threaded rod is rotatably provided on the side of the operating table. The feeding plate and the threaded rod are threadedly connected. A gear is located at the end of the threaded rod. A moving rod extends downward from the bottom of the lower plate. A transverse tooth is provided near the lower end of the moving rod. The transverse tooth in the moving rod meshes with the gear at the end of the threaded rod. When the lower plate moves downward to stamp, the moving rod drives the threaded rod to rotate, so that the feeding plate moves to the upper part of the lower die. The stamping material on the feeding plate falls into the positioning groove on the surface of the lower die for stamping.

[0014] Furthermore, a storage box for collecting finished products is provided on the side of the operating table, and a guide plate is provided between the storage box and the lower mold to allow the finished products on the lower mold to slide into the storage box.

[0015] Furthermore, a finished product removal structure is provided between the lower plate and the operating table. The finished product removal structure includes a connecting rod, which is fixedly connected to the bottom of the lower plate. The connecting rod extends downward through the operating table. A connecting arm is provided at the bottom of the operating table. The connecting rod and the connecting arm are slidably connected. A baffle is formed around the bottom of the connecting rod. A spring is provided between the baffle and the connecting arm. A push block is provided at the upper part of the connecting arm. The push block passes through the operating table and is slidably positioned in the stamping groove at the top of the operating table.

[0016] In summary, the beneficial effects of the present invention are as follows:

[0017] 1. The present invention drives the crank to rotate through the hydraulic cylinder in the stamping drive structure. The crank drives the first rod to rotate downward, which ultimately causes the upper die to stamp the stamping material on the lower die downward. Under the leverage force of the crank and the first rod, the stamping force of the hydraulic cylinder is increased, so that the stamping force of the hydraulic cylinder is maximized.

[0018] 2. When performing machining according to the present invention, the stamping material is placed on the lower die. The distance between the upper die and the lower die is adjusted according to the thickness of the stamping material by means of the height adjustment component. During stamping, the first rod and the second rod can be made completely vertical, so that the pressure of the hydraulic cylinder can be maximized.

[0019] 3. By rotating the push plate in the pulley moving structure, the roller slide rail moves upward to contact the bottom of the lower mold. Pulling the lower mold outward can remove the lower mold from the upper part of the operating table. By pushing the lower mold in the opposite direction, the lower mold can be installed on the upper part of the operating table. This structure makes the lower mold and the operating table slide together, which is convenient for the user to remove or install the lower mold.

[0020] 4. During the stamping process, the feeding plate is driven by the threaded rod in the automatic feeding structure to feed the material. After the stamping is completed, the push block in the finished product removal structure works in conjunction with the feeding plate to push the finished product out of the lower mold. When the feeding plate feeds again, it pushes the finished product to the outside of the lower mold. This invention does not require manual loading and unloading during the stamping process, effectively preventing the occurrence of safety accidents. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0031] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 The image shows a new type of press for machining.

[0032] Reference Figures 1-3As shown, the first embodiment of the present invention discloses a novel machining press, including a housing 1 and a stamping assembly mounted on the housing 1. The housing 1 has an operating table 2 on its upper part. 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 located above the connecting column 38, and the lower plate 31 is located below the upper plate 32. The lower plate 31 and the connecting column 38 are slidably connected. An upper mold 35 is fixedly installed at the center of the bottom of the lower plate 31. A stamping drive structure is provided between the upper plate 32 and the lower plate 31. The stamping drive 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 is rotatably connected to the upper plate 32, and the other end of the crank 37 is connected to the hydraulic cylinder 33. Under the leverage force of the crank 37, the pressure of the hydraulic cylinder 33 is increased. A connecting rod assembly is fixedly connected to the end of the crank 37 away from the hydraulic cylinder 33. The connecting rod assembly includes a first rod body 34 fixedly connected to the crank 37. A second rod body 39 is hinged to 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 lower mold 36 is located at the bottom of the upper mold 35. The lower mold 36 is located on the upper part of the operating table 2.

[0033] A height adjustment component is provided between the upper plate 32 and the connecting column 38. Due to the different thicknesses of the stamping materials, the distance between the upper mold 35 and the lower mold 36 is adjusted by the height adjustment component during stamping. During stamping, the first rod 34 and the upper mold 35 can be fully extended, thereby giving full play to the maximum pressure of the hydraulic cylinder 33. Preferably, the height adjustment component includes a motor 46, which is located on the upper part of the upper plate 32 and has a thread on the upper end of the connecting column 38. Transmission components 48 are rotatably installed at the four corners of the upper plate 32. The transmission components 48 are threadedly connected to the thread on the upper end of the connecting column 38. One of the transmission components 48 on the upper plate 32 is connected to the motor 46 by a chain 47. The multiple transmission components 48 on the upper part of the upper plate 32 are connected by the chain 47. In use, the motor 46 drives the chain 47 to rotate, so that the upper plate 32 moves up or down on the thread on the top of the connecting column 38, thereby adjusting the distance between the upper die 35 and the lower die 36 according to the thickness of the stamping material.

[0034] Reference Figure 4 and Figure 5As shown, the upper part of the operating table 2 is provided with a pulley moving structure. By making the pulley moving structure contact the bottom of the lower mold 36, the lower mold 36 and the operating table 2 are slidably connected, which facilitates the disassembly or installation of the lower mold 36. Preferably, the pulley moving structure includes a roller slide rail 41 disposed at the bottom of the lower mold 36, and a recessed groove with two through sides located at the top of the operating table 2. The roller slide rail 41 is disposed in the groove at the top of the operating table 2, and a first protrusion 21 and a second protrusion 22 are respectively provided on both sides of the operating table 2 protruding outward. The first protrusion 21 and the second protrusion 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 is eccentrically connected to the first protrusion 21, and the other end of the roller slide rail 41 is eccentrically connected to the second protrusion 22. A push plate 42 is rotatably connected to the side of the first protrusion 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 up or down. A linkage rod 44 connects the parts, allowing the two ends of the roller slide rail 41 to move upward or downward simultaneously. A spring pin 43 is located at the bottom of the first protrusion 21. After the push plate 42 is rotated downward, the roller slide rail 41 moves down into the groove at the top of the operating table 2. The rotation position of the push plate 42 is locked by the spring pin 43. An outer slide rail 45 is hinged to the end of the roller slide rail 41 near the second protrusion 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 locking connection. The outer slide rail 45 allows the lower mold 36 to be moved onto the outer slide rail 45, facilitating the disassembly or installation of the lower mold 36.

[0035] When machining using this invention, the stamping material is placed on the lower die 36. Based on the thickness of the stamping material, the distance between the upper die 35 and the lower die 36 is adjusted using a height adjustment component, maximizing the pressure of the hydraulic cylinder 33. The hydraulic cylinder 33 drives the crank 37 to rotate, which in turn drives the first rod 34 to rotate downwards. Ultimately, the upper die 35 stamps the stamping material on the lower die 36 downwards. Under the leverage force of the crank 37 and the first rod 34, the pressure of the hydraulic cylinder 33 increases. By rotating the push plate 42, the roller slide rail 41 moves upwards to contact the bottom of the lower die 36. Pulling the lower die 36 outwards removes it from the upper part of the operating table 2. By pushing the lower die 36 in the opposite direction, it can be installed back onto the upper part of the operating table 2. This structure creates a sliding connection between the lower die 36 and the operating table 2, facilitating the user's removal and installation of the lower die 36.

[0036] The second embodiment of the present invention, referred to Figures 6-7As shown, an automatic feeding structure is provided on the upper part of the operating table 2. This automatic feeding structure includes a storage box 52 and a feeding plate 54. A support platform 51 is provided on the upper part of the operating table 2. The storage box 52 is located on the upper part of the support platform 51. The storage box 52 has openings at both the top and bottom. A feed port is located at the top of the support platform 51. The bottom opening of the storage box 52 is connected to the feed port at the top of the support platform 51. Multiple stamping materials are placed into the storage box 52 for stamping. A support platform 53 is provided at the bottom of the feed port in the support platform 51. The side wall of the support platform 53 is connected to the side wall of the lower mold 36, and the upper surface of the support platform 53 is on the same horizontal plane as the upper surface of the lower mold 36. The surface of the lower mold 36 has a positioning groove, and the bottom of the positioning groove has a stamping groove located between the support platform 53 and the feed port at the top of the support platform 51. A feed plate 54 is laterally movable and has a through discharge port. The stamping material in the storage box 52 moves to the discharge port on the feed plate 54 under its own gravity. A threaded rod 55 is rotatably mounted on the side of the operating table 2. The feed plate 54 and the threaded rod 55 are threaded together. A gear is located at the end of the threaded rod 55. A moving rod 56 extends downward from the bottom of the lower plate 31. A transverse tooth is provided near the lower end of the moving rod 56. The transverse 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 to stamp, the moving rod 56 drives the threaded rod 55 to rotate, so that the feed plate 54 moves to the upper part of the lower mold 36. The stamping material on the feed plate 54 falls into the positioning groove on the surface of the lower mold 36 for stamping.

[0037] Reference Figure 6 As shown, a storage box 8 for collecting finished products is provided on the side of the operating table 2. A guide plate is provided between the storage box 8 and the lower mold 36 to allow the finished products on the lower mold 36 to slide into the storage box 8. (Refer to...) Figure 8As shown, 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 extends downward through the operating table 2. A connecting arm 65 is provided at the bottom of the operating table 2. The connecting rod 62 and the connecting arm 65 form a sliding connection. A baffle 64 is formed around the bottom of the connecting rod 62. A spring is provided between the baffle 64 and the connecting arm 65. A push block 61 is provided at the upper part of the connecting arm 65. The push block 61 passes through the operating table 2 and slides in the stamping groove at the top of the operating table 2. When the lower plate 31 moves downward to perform the stamping operation, the lower plate 31 drives the connecting rod 62 to move downward, and the spring 63 drives the push block 61 to move to the bottom of the stamping groove in the lower mold 36. When the lower plate 31 moves upward, under the elastic force of the spring between the connecting arm 65 and the baffle 64, the push block 61 moves upward to push the stamped finished product in the lower mold 36 upward. When the lower plate 31 performs the downward stamping again, during the process of the feeding plate 54 moving towards the lower mold 36, the finished product pushed out by the push block 61 is pushed into the storage box 8 through the end of the feeding plate 54.

[0038] When the lower plate 31 moves downwards for stamping in this invention, it drives the feeding plate 54 in the automatic feeding structure to move towards the lower mold 36, thereby moving the stamping material in the storage box 52 onto the lower mold 36 for stamping. After stamping, the lower plate 31 drives the push block 61 to move upwards during its upward movement, pushing the finished product out of the lower mold 36. When the lower plate 31 stamps downwards again, the end of the feeding plate 54 pushes the finished product pushed out by the push block 61 into the storage box 8. This invention can automatically move the stamping material into the lower mold 36 for stamping through the automatic feeding structure, eliminating the need for manual feeding. Furthermore, 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, eliminating the need for manual removal from the lower mold 36. Since no manual operation is required during the stamping process, it effectively prevents accidents caused by hydraulic presses during stamping.

The various components mentioned in this invention are common technologies in the existing field. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
