Description

Technical Field

[0001] This invention relates to the field of stainless steel processing technology, and more specifically to a hydraulic stamping and forming device for stainless steel plates. Background Technology

[0002] C-shaped steel is a widely used steel structure profile in modern construction engineering, primarily made from carbon steel. This profile features a unique C-shaped cross-section design, offering superior overall structural strength and rigidity compared to ordinary profiles, enabling it to stably bear the building's self-weight and various external loads. Currently, in industrial production, C-shaped steel is generally formed using a one-piece stamping process from steel plates.

[0003] Currently, the industry primarily relies on traditional hydraulic punch presses to process C-shaped steel. After completing a single stamping process, the punch of a traditional hydraulic punch press enters an idle standby state. Operators must manually remove the formed C-shaped steel workpiece from the mold and reposition the raw steel sheet before the next stamping cycle can begin. Each stamping cycle incurs a fixed amount of manual material handling time, significantly reducing the effective operating rate of the equipment and directly leading to low overall stamping production efficiency. Furthermore, when stamping and shaping steel sheets with poor plasticity, residual stress within the blank is concentrated and released in the bending area, easily causing cracks, tears, and other quality defects at the bending points. This significantly reduces the yield rate of finished C-shaped steel products, increasing production losses and processing costs.

[0004] Therefore, there is an urgent need to design a hydraulic stamping and forming device for stainless steel plates to solve the above problems. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a hydraulic stamping and forming device for stainless steel plates to solve the problems existing in the background art.

[0006] The present invention provides the following technical solution: a stainless steel plate hydraulic stamping forming device, including a stamping table, a guide rod provided on the top of the stamping table, a top plate provided on the top of the guide rod, a hydraulic component provided through the top of the top plate, the hydraulic component being movably disposed outside the guide rod, a guide rail being movably disposed on the top surface of the stamping table, and mold components being fixedly disposed at equal intervals on the top surface of the guide rail, the mold components being arranged parallel to the hydraulic component and located below it; It also includes a feeding rack, which is arranged on the side of the stamping table and symmetrical about the center of the stamping table, and is flush with the guide rail. The upper surface of the feeding rack is provided with a feeding component and a conveying component. The top of the feeding rack is equipped with a mounting frame, and the conveying assembly is mounted on the mounting frame, with the feeding assembly located below the conveying assembly.

[0007] Furthermore, the hydraulic assembly includes an upper stamping die, a hydraulic head, and stamping die blocks. The upper stamping die is movably disposed on the outside of the guide rod. One end of the hydraulic head is disposed through the top of the top plate, wherein the output end of the hydraulic head is fixedly connected to the top of the upper stamping die, and the stamping die blocks are equidistantly disposed on the bottom surface of the upper stamping die.

[0008] Furthermore, the mold assembly includes a lower stamping die, a stamping groove, a combustion hole, a flow divider cavity, and a flow divider branch pipe. The lower stamping die is fixedly mounted on the top surface of the guide rail. The stamping groove is formed on the top surface of the lower stamping die. The flow divider cavity is formed in the middle of the lower stamping die and is arranged in a "Y" shape. The flow divider branch pipe is arranged on the outside of the lower stamping die and is connected to the flow divider branch pipe. The combustion hole is formed on the inside of the stamping groove and is connected to the flow divider cavity.

[0009] Furthermore, the branch pipe consists of a main pipe and branch pipes, wherein the branch pipes are respectively connected to the branch cavity provided on the lower stamping die, and an external air supply pipe can be connected to the main pipe, wherein a stamping right angle is provided at the position of the stamping groove near the top of the lower stamping die.

[0010] Furthermore, the feeding assembly includes a pneumatic feeding platform, which is disposed on the surface of the feeding rack. The pneumatic feeding platform consists of a pneumatic telescopic cylinder and a loading platform, with the loading platform disposed at the output end of the pneumatic telescopic cylinder.

[0011] Furthermore, the conveying assembly includes a conveying guide rail, a drive motor, and a rubber wheel. The conveying guide rail is fixedly mounted on the inner side of the mounting frame, the drive motor is fixedly mounted on the inner side of the conveying guide rail, and the rubber wheel is fixedly mounted on the output end of the drive motor.

[0012] Furthermore, the conveying assembly also includes a miniature pneumatic telescopic cylinder, a feeding port, and a clamping plate. The miniature pneumatic telescopic cylinder is fixedly mounted on the outer surface of the feeding frame, the feeding port is opened on the surface of the feeding frame, and the clamping plate is movably mounted on the side of the conveying guide rail. The bottom surface of the clamping plate is fixedly connected to the output end of the miniature pneumatic telescopic cylinder.

[0013] Furthermore, the top surface of the stamping table is provided with two sets of sliding grooves that are adapted to the guide rail, and one end of the guide rail can be connected to a push handle.

[0014] Furthermore, the outer side of the guide rail is provided with a positioning hole, and the inner wall of the sliding groove is provided with an elastic positioning protrusion, wherein the position of the elastic positioning protrusion is adapted to the position of the stamping mold block.

[0015] The technical effects and advantages of this invention are as follows: This invention integrates a Y-shaped flow divider cavity, flow divider branch pipe, and combustion hole structure inside the lower stamping die, allowing for the connection of natural gas as a heat source to achieve targeted preheating of critical areas in the bending process of the stainless steel sheet to be stamped. Stainless steel sheets inherently have high hardness and poor ductility, making them prone to tearing, chipping, and uneven deformation during room temperature stamping. This device, through preheating, can rapidly improve the local plasticity of the sheet, fundamentally reducing stamping cracks and damage.

[0016] This invention, through the setting of a symmetrical feeding rack and integrated feeding and conveying components, uses a pneumatic telescopic cylinder on the pneumatic feeding platform to automatically lift the steel plate. Combined with a conveying mechanism consisting of a miniature pneumatic telescopic cylinder, clamping plate, drive motor, and rubber wheels, it achieves automatic clamping, stable conveying, and precise unloading of stainless steel plates, completely replacing the traditional manual handling and alignment feeding operation mode. Simultaneously, the design of the clamping plate embedding steel balls and using rubber wheels for friction conveying effectively avoids scratches, deviations, and jamming during plate conveying, ensuring stability and accuracy over long distances and significantly reducing manual labor intensity.

[0017] This invention revolutionizes traditional manual and forced demolding methods by incorporating a positioning spring and bracket on the end face of the lower stamping die. During the steel plate stamping process, the demolding bracket is compressed downwards, and the positioning spring is compressed and stores energy. After stamping is completed, the hydraulic components are lifted, the spring elastically returns to its original position, releasing potential energy, and the demolding bracket automatically pushes the formed C-shaped steel out of the stamping groove, completing automatic demolding.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention necessarily exceeds the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but still fall within the protection scope of this application.

[0021] Figures 1-14 This is the preferred embodiment of the present invention, which is described below in conjunction with the accompanying drawings. Figure 1 - Appendix Figure 14 The present invention will be further described below.

[0022] A hydraulic stamping forming device for stainless steel plates includes a stamping table 1, a guide rod 5 on the top of the stamping table 1, a top plate 3 on the top of the guide rod 5, a hydraulic component through the top of the top plate 3, the hydraulic component being movably disposed outside the guide rod 5, a guide rail 8 being movably disposed on the top surface of the stamping table 1, and mold components being fixedly disposed at equal intervals on the top surface of the guide rail 8, the mold components being arranged parallel to the hydraulic component and located below it. It also includes a feeding rack 7, which is set on the side of the stamping table 1 and symmetrically arranged about the center of the stamping table 1, and flush with the guide rail 8. The upper surface of the feeding rack 7 is provided with a feeding component and a conveying component. The top of the feeding rack 7 is provided with a mounting frame 10, the conveying component is mounted on the mounting frame 10, and the feeding component is located below the conveying component.

[0023] Specifically, the hydraulic components include an upper stamping die 2, a hydraulic head 4, and a stamping die block 15. The upper stamping die 2 is movably disposed on the outside of the guide rod 5. One end of the hydraulic head 4 is disposed through the top of the top plate 3. The output end of the hydraulic head 4 is fixedly connected to the top of the upper stamping die 2. The stamping die block 15 is equidistantly disposed on the bottom surface of the upper stamping die 2.

[0024] In this embodiment, a hydraulic component is used to drive the stamping mold block 15 to stamp the lower stamping die 9 at the bottom of the guide rail 8. Before stamping, the stainless steel to be stamped is placed on top of the lower stamping die 9. The stamping mold block 15 is driven by the hydraulic head 4, which drives the upper stamping die 2 to rise and fall along the outside of the guide rod 5.

[0025] Specifically, the mold assembly includes a lower stamping die 9, a stamping groove 21, a combustion hole 22, a flow divider cavity 23, and a flow divider branch pipe 20. The lower stamping die 9 is fixedly mounted on the top surface of the guide rail 8. The stamping groove 21 is opened on the top surface of the lower stamping die 9. The flow divider cavity 23 is opened in the middle of the lower stamping die 9, and the flow divider cavity 23 is arranged in a "Y" shape. The flow divider branch pipe 20 is located on the outside of the lower stamping die 9 and is connected to the flow divider branch pipe 20. The combustion hole 22 is opened on the inside of the stamping groove 21 and is connected to the flow divider cavity 23. The end face of the lower stamping die 9 is provided with a mounting groove, and a positioning spring 13 is provided inside the mounting groove. A release bracket 12 is sleeved on the outside of the positioning spring 13.

[0026] In this embodiment, a mold assembly is used to cooperate with the stamping mold block 15 on the bottom surface of the upper stamping die 2 to stamp the steel plate placed on the top of the lower stamping die 9 into a C-shaped steel. The stamping groove 21 in the middle of the lower stamping die 9 is used to stamp the steel plate. The mounting groove on the end face of the lower stamping die 9 is used to install the ejector 12 and the positioning spring 13. The positioning spring 13 consists of a metal guide rod and a spring. One end of the spring contacts the bottom end of the ejector 12. The ejector 12 is sleeved on the outside of the metal guide rod. The ejector 12 is used to support the steel plate to be stamped. It should be noted that the ejector 12 and the positioning spring 13 are both made of metal. The branch pipe 20 consists of a main pipe and a branch pipe. The branch pipes are respectively connected to the branch cavity 23 on the lower stamping die 9. An external air supply pipe can be connected to the main pipe. The stamping groove 21 is provided with a stamping right angle near the top of the lower stamping die 9.

[0027] The stainless steel plate to be stamped is placed flat on top of the ejector 12 and parallel to the top of the lower stamping die 9. The branch pipe 20 is connected to an external combustion gas source. In this scheme, natural gas can be used as the heating source. The external pipe is not shown in the diagram, but this does not affect the implementation of the scheme. It should be noted that the branch pipes 20 on both sides of each lower stamping die 9 are connected by a conduit passing through the lower stamping die 9. Alternatively, in this scheme, the branch pipes 20 on several lower stamping dies at the top of the guide rail 8 can be connected by conduits. The natural gas diverted through the branch pipes 20 enters each branch chamber 23 and is ejected through the combustion hole 22 and the round hole at the top of the lower stamping die 9. Ignition of this natural gas heats the stainless steel plate placed on top of the ejector 12. This calcination heating rapidly increases the temperature of the steel plate, improving its plasticity and reducing the possibility of tearing during stamping.

[0028] In this embodiment, steel plates can be placed in batches on top of the bracket 12. Heating of the bending area of ​​the steel plates can be performed simultaneously, or selective heating can be chosen based on the physical properties of the steel plates. After heating, the steel plates move under the conveying of the guide rail 8 to directly below the stamping mold block 15. The movement of the guide rail 8 is achieved by manually pushing the handle on its end face, driving the lower stamping die 9 to move below the stamping mold block 15. Then, the hydraulic head 4 is controlled to drive the upper stamping die 2 and the stamping mold block 15 downwards together to stamp the steel plates. When the steel plates are stamped, they compress the bracket 12. At this time, the spring on the positioning spring 13 is compressed and stores a certain amount of pressure. The steel plate is extruded into a C-shaped steel under the extrusion action of the stamping die block 15 and the stamping groove 21. When the stamping die block 15 moves away from the lower stamping die 9 under the drive of the hydraulic head 4, the formed steel plate moves upward under the action of the bracket 12 and the positioning spring 13, causing it to separate from the stamping groove 21. The driving source of the bracket 12 comes from the elastic potential energy stored in the positioning spring 13, which is released by the elastic kinetic energy released when the spring returns to its original state to lift the bracket 12, thereby realizing the separation of the formed steel plate from the stamping groove 21. The stamped steel plate is transported to the other end of the stamping table 1 by the guide rail 8, and then the formed C-shaped steel is removed from the top of the bracket 12 by manual handling.

[0029] Specifically, the feeding assembly includes a pneumatic feeding platform 16, which is set on the surface of the feeding rack 7. The pneumatic feeding platform 16 consists of a pneumatic telescopic cylinder and a loading platform, with the loading platform set at the output end of the pneumatic telescopic cylinder.

[0030] In this embodiment, a feeding assembly is used to transport the steel plate to be stamped. The specific operation is as follows: the steel plate is placed on the loading platform through the feeding port 18, and the pneumatic telescopic cylinder is driven to lift it upward, so as to transport the steel plate to the clamping plate 19 set inside the conveying guide rail 6. It should be noted that the pneumatic telescopic cylinder is existing technology, and it can be used in conjunction with this device to lift the steel plate without disclosing its specific structure. The width of the loading platform is smaller than the width of the steel plate. When the steel plate is raised to its highest point, a miniature pneumatic telescopic cylinder 17 located on the outer side of the loading rack 7 is driven. It should be noted that the miniature pneumatic telescopic cylinder 17 is existing technology and can be used in conjunction with this device without disclosing its specific structure to drive the clamping plate 19. The clamping plate 19 expands along the end face of the conveyor rail 6 under the contraction movement of the miniature pneumatic telescopic cylinder 17. Simultaneously, the steel plate is placed inside the conveyor rail 6 by the use of the loading assembly. Then, the clamping plate 19 is retracted by controlling the miniature pneumatic telescopic cylinder 17. At this time, the steel plate is clamped to the top surface of the conveyor rail 6 and the clamping plate 19, and the rubber wheel 24 contacts the upper surface of the steel plate. The steel plate is conveyed by the friction of the rotating rubber wheel 24. The top surface of the clamping plate 19 is embedded with steel balls to achieve long-distance conveying of the steel plate. When the steel plate is conveyed to the end, the clamping plate 19 expands along the end face of the conveying guide rail 6 under the contraction movement of the micro pneumatic telescopic cylinder 17. The support force of the clamping plate 19 on the steel plate disappears and it falls vertically to the top of the bracket 12 under the action of gravity. Due to the weight of the steel plate, the bracket 12 will move down a certain distance along the metal guide rod on the positioning spring 13, so that the lower surface of the steel plate is close to the combustion hole 22. The gas sprayed from the combustion hole 22 is ignited to achieve local heating of the steel plate. The ignition can be done manually.

[0031] Specifically, the conveying assembly includes a conveying guide rail 6, a drive motor 14, and a rubber wheel 24. The conveying guide rail 6 is fixedly installed inside the mounting frame 10, the drive motor 14 is fixedly installed inside the conveying guide rail 6, and the rubber wheel 24 is fixedly installed at the output end of the drive motor 14. The conveying assembly also includes a miniature pneumatic telescopic cylinder 17, a feeding port 18, and a clamping plate 19. The miniature pneumatic telescopic cylinder 17 is fixedly installed on the outer surface of the feeding frame 7, the feeding port 18 is opened on the surface of the feeding frame 7, and the clamping plate 19 is movably installed on the side of the conveying guide rail 6. The bottom surface of the clamping plate 19 is fixedly connected to the output end of the miniature pneumatic telescopic cylinder 17.

[0032] In this embodiment, a conveying guide rail 6 is used to support and transport the steel plate. Specifically, a drive motor 14, which is equidistantly arranged on the conveying guide rail 6, is energized to drive the rubber wheel 24 at a constant speed, thereby transporting the steel plate. The drive motor 14 can be driven by an external power source. Optionally, the drive motor 14 can be a DC motor with a working voltage of 12 volts. The clamping plate 19 is moved by controlling the micro pneumatic telescopic cylinder 17. At this time, the steel plate is clamped to the top surface of the conveying guide rail 6 and the clamping plate 19, and the rubber wheel 24 contacts the upper surface of the steel plate. The friction of the rotating rubber wheel 24 is used to transport the steel plate. Steel balls are movably embedded in the top surface of the clamping plate 19, thereby realizing the long-distance transport of the steel plate.

[0033] Specifically, the top surface of the stamping table 1 is provided with two sets of sliding grooves that are adapted to the guide rail 8. One end of the guide rail 8 can be connected to a push handle. The outer side of the guide rail 8 is provided with a positioning hole. The inner wall of the sliding groove is provided with an elastic positioning protrusion, wherein the position of the elastic positioning protrusion is adapted to the position of the stamping mold block 15.

[0034] In this embodiment, the lower stamping die 9 on the guide rail 8 is pushed to the bottom of the stamping mold block 15 by manually pushing the push handle at one end of the guide rail 8, so as to process the steel plate placed on the lower stamping die 9. The positioning hole on the outer side of the guide rail 8 and the elastic positioning protrusion on the inner wall of the sliding groove are used to position the lower stamping die 9, thereby ensuring that at least three sets of lower stamping dies 9 are located directly below the stamping mold block 15 to realize the stamping processing of batch steel plates.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
