Description

Technical Field

[0001] This invention belongs to the field of hydraulic presses, specifically relating to a hydraulic press for powder products that integrates an oil-electric system with a frame. Background Technology

[0002] A hydraulic press is a machine that uses the static pressure of a liquid to process products made of metal, plastic, rubber, wood, powder, etc. It is commonly used in pressing and forming processes, such as forging, stamping, cold extrusion, straightening, bending, flanging, deep drawing of thin plates, powder metallurgy, and press fitting. The working medium used in a hydraulic press not only transmits pressure but also ensures that the machine's working parts are sensitive, reliable, have a long service life, and have minimal leakage. There are many types of hydraulic presses, and powder hydraulic presses are one of the most widely used.

[0003] In powder hydraulic presses, the frame and hydraulic system are usually independent and not connected. The multiple oil pump motors of the hydraulic system are connected to the corresponding hydraulic cylinders through oil pipes, which are directly exposed to the outside. If the hydraulic system is integrated with the frame, the high-pressure oil has a lot of energy when the hydraulic cylinder is pumped and lifted. After the pressing work is completed and the powder product is pushed, the oil pipe system is prone to deformation under pressure. When the pressure is maintained after pressing, the system stores a considerable amount of energy. Once the pressure is released, there is a potential for failure and safety hazards. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a hydraulic press for powder products that integrates the hydraulic and electrical system with the frame. This integration ensures the concealed reliability of the pipeline, effectively prevents the pipeline from being squeezed and deformed, and avoids potential failures and safety hazards.

[0005] The objective of this invention is achieved through the following technical solution: a hydraulic press for powder products integrating an oil and electricity system and a frame, comprising a frame and an upper mold frame assembly and a lower mold frame assembly placed on the frame, an oil and electricity system integrally connected to the frame, the oil and electricity system including an electrical control box disposed on the surface of the frame, an electrical control box disposed on the surface of the frame, and an oil pump motor assembly disposed within the electrical control box; The upper mold frame assembly includes an upper hydraulic cylinder, an upper movable crossbeam, and an upper punch plate located at the drive end of the upper hydraulic cylinder; the lower mold frame assembly includes a lower hydraulic cylinder and a lower movable crossbeam; there is a pressing platform between the upper punch plate and the lower movable crossbeam, the upper hydraulic cylinder and the lower hydraulic cylinder are arranged vertically and vertically, and there is a pusher hydraulic cylinder on the side of the pressing platform to push out the pressed finished product. The oil pump motor unit includes multiple oil pump motors. One oil pump motor is connected to the upper hydraulic cylinder through oil pipe 1, one oil pump motor is connected to the lower hydraulic cylinder through oil pipe 2, and another oil pump motor is connected to the pusher hydraulic cylinder through oil pipe 3. The electrical control frame also has a pipeline limiting and buffering displacement structure that gradually buffers and guides multiple oil pipes. The pipeline limiting and buffering displacement structure includes a connecting rod fixing seat set on the inner side wall of the electrical control frame and a connecting rod drive assembly movably connected to the connecting rod fixing seat. The connecting rod drive assembly has two clamping components 1 that position and buffer oil pipe 1 and oil pipe 2 respectively, and a clamping component 2 that positions and buffers oil pipe 3. The connecting rod drive assembly synchronously drives the two clamping components 1 to move in opposite directions or in opposite directions and the clamping component 2 to move laterally horizontally back and forth.

[0006] A further improvement of the present invention is that: the linkage drive assembly includes a connecting base corresponding to the linkage fixing seat, a displacement rod between the connecting base and the linkage fixing seat, sliding blocks at both axial ends of the displacement rod, a first linkage and a second linkage being movably connected between the upper end of the side end face of the sliding block and the linkage fixing seat and the connecting base respectively, a connecting shaft rod one passing through the first linkage, the second linkage and the corresponding sliding block, a third linkage and a fourth linkage being movably connected between the lower end of the side end face of the sliding block and the linkage fixing seat and the connecting base respectively, a connecting shaft rod two passing through the third linkage, the fourth linkage and the corresponding sliding block, the first linkage and the second linkage being axially symmetrical about the displacement rod as the central axis, the third linkage and the fourth linkage being axially symmetrical about the displacement rod as the central axis, and the first linkage and the third linkage being axially symmetrical about the vertical line in the same plane of the displacement rod as the central axis; The linkage drive assembly also includes a rack mounted on the inner wall of the electrical control frame and a geared motor mounted on the end of the displacement rod. The drive end of the geared motor is fixedly connected to the end of the displacement rod, and the drive end of the geared motor is fitted with a gear that meshes with the corresponding rack. The extension direction of the rack is perpendicular to the axial direction of the displacement rod. When the geared motor is started, it drives the gear on the displacement rod to move horizontally on the corresponding rack, thereby driving the horizontal displacement of the displacement rod, which in turn drives the two sliding blocks on the displacement rod to move towards or away from each other, and simultaneously drives the connecting base to move horizontally.

[0007] A further improvement of the present invention is that: the clamping assembly includes a clamping body 1 disposed on the outer end of the connecting shaft 1 at the upper position; the clamping body 1 has a circular cavity 1 and a circular clamping cavity 1 distributed along the vertical direction of the displacement rod; the inner wall of the circular clamping cavity 1 has clamping blocks 1 on both sides; an electric push rod 1 is provided between the clamping blocks 1 and the circular clamping cavity 1; an oil pipe 1 vertically penetrates the circular clamping cavity 1 and is clamped and positioned by the clamping blocks 1; an oil pipe 2 vertically penetrates the circular cavity 1 and has a gap between it and the circular cavity 1. The clamping assembly also includes a clamping body 2 located at the lower side of the outer end of the connecting shaft 2. The clamping body 2 has a circular cavity 2 and a circular clamping cavity 2 distributed along the vertical direction of the displacement rod. The circular clamping cavity 1 and the circular clamping cavity 2 are staggered vertically. The inner wall of the circular clamping cavity 2 has clamping blocks 2 on both sides. There is an electric push rod 2 between the clamping blocks 2 and the circular clamping cavity 2. The oil pipe 2 vertically penetrates the circular clamping cavity 2 and is clamped and positioned by the clamping blocks 2. The oil pipe 1 vertically penetrates the circular cavity 2 and has a gap between it and the circular cavity 2.

[0008] A further improvement of the present invention is that: the clamp holding assembly 2 includes a clamp body 3 disposed on the outer end of the connecting base, the clamp body 3 having a circular clamping cavity 3 that vertically penetrates the oil pipe 3, the inner wall of the circular clamping cavity 3 having clamping blocks 3 on both sides, and an electric push rod 3 between the clamping blocks 3 and the circular clamping cavity 3.

[0009] A further improvement of the present invention is that: the upper and lower ends of the connecting rod fixing seat are connected to a limiting frame in the direction of the displacement rod, and the limiting frame has a limiting through hole for accommodating the end of the displacement rod to pass through and move horizontally as a whole, and the width of the limiting through hole is the same as the diameter of the displacement rod.

[0010] A further improvement of the present invention is that the inner walls of clamping block one, clamping block two and clamping block three are all provided with a rubber buffer layer to buffer the oil pipe.

[0011] Compared with the prior art, the present invention has the following advantages: 1. In this invention, the frame and the oil and electricity system are integrated into one design, which saves floor space, facilitates transportation, greatly shortens the user's installation time, improves installation efficiency, optimizes the layout of oil pipes and lines, and makes the lines and pipelines concealed and reliable.

[0012] 2. This invention features a pipeline limiting and buffering displacement structure that clamps and limits multiple oil pipes connected to the upper hydraulic cylinder, lower hydraulic cylinder, and pushing hydraulic cylinder. The connecting rod drive assembly synchronously drives the two clamping components one to move in opposite directions or backwards, and the clamping component two to move laterally horizontally back and forth. During a single pressing stroke, the up-and-down back and forth movement of the upper and lower hydraulic cylinders provides a certain buffering displacement space for oil pipe one and oil pipe two. Simultaneously, the horizontal back and forth movement of the pushing hydraulic cylinder provides a certain buffering displacement space for oil pipe three, buffering the vibrations generated on multiple oil pipes when multiple hydraulic cylinders rapidly rebound. The pipeline limiting and buffering displacement structure in this application not only buffers the vibrations generated on multiple oil pipes when multiple hydraulic cylinders rapidly rebound, but also provides good support and stability for multiple oil pipes. Its layout is reasonable and neat, integrating the hydraulic and electrical system with the frame, ensuring the concealed reliability of the pipelines, effectively preventing pipeline extrusion deformation, and avoiding potential faults and safety hazards.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can be described as a mechanical connection, a direct connection, or a connection through an intermediate medium. Those skilled in the art can understand the basic meaning of the above terms in this invention according to the specific circumstances.

[0023] A hydraulic press for powder products integrating the oil-electric system and the frame, with reference to Figure 1 , Figure 2 It includes a frame 1 and an upper mold frame assembly 2 and a lower mold frame assembly 3 placed on the frame 1. The frame 1 also has a sealed electrical control frame 4. An integrated hydraulic system is connected to the frame 1. The hydraulic system includes an electrical control box 5 set on the surface of the frame 1 and an oil pump motor unit 6 inside the electrical control frame 4. The upper mold frame assembly 2 includes an upper hydraulic cylinder 21, an upper movable crossbeam 22, and an upper punch plate 23 placed at the drive end of the upper hydraulic cylinder 21; the lower mold frame assembly 3 includes a lower hydraulic cylinder 31 and a lower movable crossbeam 32; a pressing platform 33 is provided between the upper punch plate 23 and the lower movable crossbeam 32; the upper hydraulic cylinder 21 and the lower hydraulic cylinder 31 are arranged vertically and vertically respectively; a pusher hydraulic cylinder 7 is provided on the side of the pressing platform 33 to push out the pressed finished product. The oil pump motor unit 6 includes multiple oil pump motors 61. One oil pump motor 61 is connected to the upper hydraulic cylinder 21 through oil pipe 1 62, one oil pump motor 61 is connected to the lower hydraulic cylinder 31 through oil pipe 2 63, and another oil pump motor 61 is connected to the pusher hydraulic cylinder 7 through oil pipe 3 64. The electrical control frame 4 also has a pipeline limiting and buffering displacement structure 8 that gradually buffers and guides multiple oil pipes. The pipeline limiting and buffering displacement structure 8 includes a connecting rod fixing seat 81 set on the inner side wall of the electrical control frame 4 and a connecting rod drive assembly 82 movably connected to the connecting rod fixing seat 81. The connecting rod drive assembly 82 has two clamping components 1 83 that respectively position and buffer oil pipe 1 62 and oil pipe 2 63. The connecting rod drive assembly 82 has a clamping component 2 84 that positions and buffers oil pipe 3 64. The connecting rod drive assembly 82 synchronously drives the two clamping components 1 83 to move in opposite directions or in opposite directions and the clamping component 2 84 to move laterally horizontally back and forth.

[0024] In this invention, the frame and the oil and electricity system are integrated into one design, which saves floor space, facilitates transportation, greatly shortens the user's installation time, improves installation efficiency, optimizes the layout of oil pipes and lines, and makes the lines and pipelines concealed and reliable.

[0025] This invention features a pipeline limiting and buffering displacement structure 8, which clamps and limits multiple oil pipes connected to the upper hydraulic cylinder 21, lower hydraulic cylinder 31, and pushing hydraulic cylinder 7. The connecting rod drive assembly 82 synchronously drives the two clamping assemblies 83 to move in opposite or opposite directions, and the clamping assembly 84 to move laterally horizontally back and forth. During a single pressing stroke, the up-and-down back and forth movement of the upper hydraulic cylinder 21 and lower hydraulic cylinder 31 provides a certain buffering displacement space for oil pipes 62 and 63. Simultaneously, the horizontal back and forth movement of the pushing hydraulic cylinder 7 provides a certain buffering displacement space for oil pipe 64, buffering the vibration generated on multiple oil pipes when multiple hydraulic cylinders rapidly rebound. The pipeline limiting and buffering displacement structure 8 in this application not only buffers the vibration generated on multiple oil pipes when multiple hydraulic cylinders rapidly rebound, but also provides good support and stability for multiple oil pipes. Its layout is reasonable and neat, integrating the hydraulic and electrical system with the frame, ensuring the concealed reliability of the pipelines, effectively preventing pipeline extrusion deformation, and avoiding potential faults and safety hazards.

[0026] Based on this embodiment, refer to Figure 3The linkage drive assembly 82 includes a connecting base 821 corresponding to the connecting rod fixing seat 81. A displacement rod 822 is located between the connecting base 821 and the connecting rod fixing seat 81. Sliding blocks 823 are located at both axial ends of the displacement rod 822. A first connecting rod 824 and a second connecting rod 825 are movably connected between the upper end of the side face of the sliding block 823 and the connecting base 821, respectively. A connecting shaft 826 passes through the first connecting rod 824, the second connecting rod 825, and the corresponding sliding block 823. The lower end of the side face of the sliding block 823 is connected to... A third link 827 and a fourth link 828 are movably connected between the link fixing seat 81 and the connecting base 821, respectively. A connecting shaft 829 passes through the third link 827, the fourth link 828 and the corresponding sliding block 823. The first link 824 and the second link 825 are symmetrically arranged about the displacement rod as the central axis. The third link 827 and the fourth link 828 are symmetrically arranged about the displacement rod 822 as the central axis. The first link 824 and the third link 827 are symmetrically arranged about the vertical line in the same plane of the displacement rod 822 as the central axis. The linkage drive assembly 82 also includes a rack 8210 disposed on the inner wall of the electrical control frame 4 and a geared motor 8211 disposed at the end of the displacement rod 822. The drive end of the geared motor 8211 is fixedly connected to the end of the displacement rod 822, and the drive end of the geared motor 8211 is fitted with a gear 8212 that meshes with the corresponding rack. The extension direction of the rack 8210 is perpendicular to the axial direction of the displacement rod 822. When the geared motor 8211 is started, it drives the gear 8212 on the displacement rod 822 to move horizontally on the corresponding rack 8210, thereby driving the displacement rod 822 to move horizontally, and then driving the two sliding blocks 823 on the displacement rod 822 to move towards or away from each other, while simultaneously driving the connecting base 821 to move horizontally.

[0027] During powder pressing, the upper hydraulic cylinder 21 moves downward to the pressing platform 33 to press the powder on the pressing platform 33 into shape. Then, the lower hydraulic cylinder 31 moves upward to move the pressed powder product upward to the top of the pressing platform 33. At this time, the pushing hydraulic cylinder 7 pushes forward to push the powder product outward.

[0028] In this application, before pressing, the linkage drive assembly 82 of the pipeline limiting buffer displacement structure 8 is started. After the reduction motor 8211 is started, the upper and lower clamping assemblies 83 move towards or away from each other in the vertical direction, and the side clamping assembly 84 moves back and forth in the horizontal direction simultaneously. This provides buffer space for the movement stroke of the upper hydraulic cylinder 21, the lower hydraulic cylinder 31 and the pushing hydraulic cylinder 7, while also supporting and positioning multiple oil pipes, effectively preventing the pipeline from being squeezed and deformed, and avoiding potential failures and safety hazards.

[0029] Based on this embodiment, refer to Figure 4, Figure 5 The clamping assembly 83 includes a clamping body 831 disposed on the outer end of the connecting shaft 826 at the upper position. The clamping body 831 has a circular cavity 832 and a circular clamping cavity 833 distributed along the vertical direction of the displacement rod 822. The inner wall of the circular clamping cavity 832 has clamping blocks 834 on both sides. An electric push rod 835 is located between the clamping blocks 834 and the circular clamping cavity 833. The oil pipe 62 vertically penetrates the circular clamping cavity 833 and is clamped and positioned by the clamping blocks 834. The oil pipe 63 vertically penetrates the circular cavity 832 and has a gap between it and the circular cavity 832. The clamping assembly 83 further includes a clamping body 836 located at the outer end of the connecting shaft 829 at the lower position. The clamping body 836 has a circular cavity 837 and a circular clamping cavity 838 distributed along the vertical direction of the displacement rod 822. The circular clamping cavity 833 and the circular clamping cavity 838 are vertically offset. The inner wall of the circular clamping cavity 838 has clamping blocks 839 on both sides. An electric push rod 8310 is located between the clamping blocks 839 and the circular clamping cavity 838. The oil pipe 63 vertically penetrates the circular clamping cavity 838 and is clamped and positioned by the clamping blocks 839. The oil pipe 62 vertically penetrates the circular cavity 837 and has a gap between it and the circular cavity 837.

[0030] This invention provides two clamping components 83 arranged vertically. The upper clamping component 83 clamps and fixes the first oil pipe 62 and limits the circumferential movement of the second oil pipe 63, while the lower clamping component 83 clamps and fixes the second oil pipe 63 and limits the circumferential movement of the first oil pipe 62. The purpose of this design is to achieve initial vertical limitation of the first oil pipe 62 and the second oil pipe 63, while also being able to clamp and move the first oil pipe 62 and the second oil pipe 63 respectively.

[0031] Based on this embodiment, refer to Figure 6 The clamp holding assembly 2 84 includes a clamp body 3 841 disposed on the outer end of the connecting base 821. The clamp body 3 841 has a circular clamping cavity 3 842 that vertically penetrates the oil pipe 3 84. There are clamping blocks 3 843 on both sides of the inner wall of the circular clamping cavity 3 842. There is an electric push rod 3 844 between the clamping blocks 3 843 and the circular clamping cavity 3 842.

[0032] Based on this embodiment, the upper and lower ends of the connecting rod fixing seat 81 are connected to the limiting frame 85 in the direction of the displacement rod 822. The limiting frame 85 has a limiting through hole 86 that allows the end of the displacement rod 822 to pass through and move horizontally as a whole. The width of the limiting through hole 86 is the same as the diameter of the displacement rod 822.

[0033] It should be noted that after the geared motor 8211 starts, the displacement rod 822 moves back and forth in the horizontal direction, and the setting of the limit frame 85 plays a certain role in limiting and guiding the horizontal displacement of the displacement rod 822, ensuring the verticality of the displacement rod 822.

[0034] Based on this embodiment, the inner walls of clamping block 1 834, clamping block 2 839 and clamping block 3 843 are all equipped with a rubber buffer layer to buffer the oil pipe.

[0035] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed.
