Description

Technical Field

[0001] This invention relates to the field of ship plate processing, and in particular to a stamping device for ship plate workpieces. Background Technology

[0002] In shipbuilding, the hull is welded from a large number of steel plates of different shapes, sizes, and thicknesses. These steel plates require multiple processing steps before assembly, among which stamping, especially punching, is a crucial step. The holes in the hull plates are mainly used for pipeline passage, equipment installation, weight reduction, and subsequent riveting or bolting connections. Therefore, the positional accuracy, efficiency, and quality of punching directly affect the assembly accuracy, overall strength, and production cycle of the hull structure. Currently, hydraulic or mechanical stamping equipment is commonly used in the punching of hull plate workpieces. The basic process is as follows: the hull plate workpiece to be processed is hoisted onto the worktable of the stamping machine, initially positioned manually, and then the stamping machine drives the die to complete the punching.

[0003] After each loading, workers need to repeatedly adjust the position of the workpiece. This process is time-consuming and labor-intensive. The frequent adjustment operations by workers near heavy equipment also pose a high safety risk. Summary of the Invention

[0004] In view of this, the present invention aims to provide a stamping device for ship plate workpieces to solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows: This invention proposes a stamping device for ship plate workpieces, characterized in that: The device includes a base plate, a mounting frame fixed to the base plate by multiple L-shaped support rods, and a work plate disposed on the base plate below the mounting frame. A hydraulic cylinder is fixedly mounted on the mounting frame, with the end of the hydraulic cylinder located inside the mounting frame and fixedly mounted on a mounting base. A punch head is fixedly mounted on the bottom surface of the mounting base. A base is detachably mounted on the top of the work plate, and a punching hole is opened on the base, extending through to the bottom of the work plate. The punching hole corresponds to the punch head. Positioning components for positioning workpieces are also symmetrically arranged on the top surface of the work plate. The positioning assembly includes a sliding rod, a fixing block, and a clamping plate. The fixing block is fixedly disposed on the top of the working plate. The sliding rod is slidably connected to the fixing block. The clamping plate is fixedly disposed on the opposite side of the two sliding rods. When clamped, the two clamping plates clamp the workpiece above the base.

[0006] Furthermore, a pull plate is fixedly provided at the other end of the sliding rod, and a second tension spring is fixedly provided between the pull plate and the fixed block. The second tension spring is provided in at least two sets, with one end fixedly connected to the fixed block and the other end fixedly connected to the pull rod.

[0007] Furthermore, the top surface of the base plate is provided with a grinding assembly, which includes a motor and a grinding roller. The motor is fixedly mounted on the top surface of the base plate, and the grinding roller is fixedly mounted on the output shaft of the motor. The grinding roller corresponds to the punching hole.

[0008] Furthermore, a bottom shell for receiving waste material is fixedly provided on the top surface of the bottom plate, and the motor is located inside the bottom shell.

[0009] Furthermore, cylinders are fixedly installed on both sides of the base plate, and the ends of the cylinders are fixedly connected to the bottom surface of the working plate.

[0010] Furthermore, a receiving assembly is provided on one side of the cylinder. The receiving assembly includes an extension plate fixedly disposed on the side wall of the base plate, a connecting block fixedly disposed on the bottom of the working plate, and a sliding block slidably disposed on the top of the base plate. The connecting block and the sliding block are connected by a support rod. One end of the support rod is hinged to the connecting block, and the other end is hinged to the sliding block. A screw is provided between the sliding rod and the extension plate. One end of the screw is rotatably connected to the sliding block, and the other end is screwed to the extension plate.

[0011] Furthermore, the mounting frame is provided with a guide plate, and the two sides of the guide plate are slidably connected to two opposite sides of the mounting frame, and the base is fixedly installed at the bottom of the guide plate.

[0012] Furthermore, the guide plate is symmetrically provided with pressing components. The pressing components include a pressing column that is slidably connected to the guide plate, an abutment plate fixedly disposed at the bottom of the pressing block, and a first tension spring fitted on the upper end of the pressing column. One end of the first tension spring is fixedly connected to the guide plate, and the other end is fixedly connected to the top end of the pressing block.

[0013] Compared with the prior art, the present invention has the following advantages: In this invention, symmetrically arranged positioning components are used to simultaneously clamp the workpiece from both sides using clamping plates, restricting the workpiece's movement in any direction within the horizontal plane. The sliding connection between the sliding rod and the fixed block ensures the linearity of the clamping force, preventing workpiece deflection or tilting due to uneven clamping force, and ensuring accurate punching position.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0019] The following will refer to the appendix. Figures 1 to 5 The present invention will be described in detail with reference to the embodiments.

[0020] Overall, the present invention proposes a stamping device for ship plate workpieces, including a base plate 6, a mounting frame 1 fixedly mounted on the base plate 6 by a plurality of L-shaped support rods 102, and a work plate 4 mounted on the base plate 6 and located below the mounting frame 1. A hydraulic cylinder 101 is fixedly mounted on the mounting frame 1, the end of the hydraulic cylinder 101 is located inside the mounting frame 1 and is fixedly mounted on a mounting base 3. A stamping head 301 is fixedly mounted on the bottom surface of the mounting base 3. A base 401 is detachably mounted on the top of the work plate 4. A stamping hole 402 is opened on the base 401 and extends through to the bottom of the work plate 4. The stamping hole 402 corresponds to the stamping head 301. Positioning components for positioning workpieces are also symmetrically arranged on the top surface of the work plate 4. The positioning assembly includes a sliding rod 501, a fixing block 504, and a clamping plate 503. The fixing block 504 is fixedly installed on the top of the working plate 4. The sliding rod 501 is slidably connected to the fixing block 504. The clamping plate 503 is fixedly installed on the opposite side of the two sliding rods 501. When clamping, the two clamping plates 503 clamp the workpiece above the base 401.

[0021] In this embodiment, the workpiece is synchronously clamped from both sides by clamping plates 503 using symmetrically arranged positioning components, restricting the workpiece's movement in any direction within the horizontal plane. The sliding connection between the sliding rod 501 and the fixed block 504 ensures the linearity of the clamping force, preventing workpiece deflection or tilting due to uneven clamping force, and ensuring the accuracy of the punching position.

[0022] During the stamping process, the enormous impact force and vibration are transmitted to the work plate 4 through the base 401, while the workpiece is firmly clamped between the clamping plates 503 on both sides, in close contact with the base 401, forming a stable whole. This greatly suppresses the minute displacement and vibration of the workpiece during the stamping process, fundamentally solving the technical problem of hole position deviation caused by cumulative errors.

[0023] In practice, the ship plate workpiece to be processed is smoothly hoisted onto the work plate 4 and positioned approximately in the center of the base 401. The operator (or via an automated drive device) simultaneously pushes or drives the sliding rods 501 of the positioning components on both sides. Guided by the fixing block 504, the sliding rods 501 slide in a straight line towards the workpiece. As the sliding rods 501 move, the clamping plates 503 fixed to them simultaneously contact the workpiece from both sides and continuously apply clamping force until the workpiece is firmly clamped between the clamping plates 503 on both sides, and the bottom of the workpiece is tightly fitted against the upper surface of the base 401. At this point, the workpiece is fully constrained in the horizontal direction, and positioning is complete.

[0024] After positioning is completed, hydraulic cylinder 101 is activated. The piston rod of hydraulic cylinder 101 extends downward, driving mounting base 3 and punch head 301 to move rapidly downward with enormous pressure. Punch head 301 penetrates the workpiece placed on base 401, knocking the waste off the workpiece. The knocked-off waste is discharged through punching hole 402 on base 401 and the space under work plate 4, completing the punching operation.

[0025] Based on the above configuration, a pull plate 5 is fixedly provided at the other end of the sliding rod 501, and a second tension spring 502 is fixedly provided between the pull plate 5 and the fixed block 504. The second tension spring 502 is provided in at least two sets, with one end fixedly connected to the fixed block 504 and the other end fixedly connected to the pull plate 5.

[0026] The positioning assembly is given the ability to automatically reset by a second tension spring 502 located between the pull plate 5 and the fixing block 504. When the external force is released, the sliding rod 501 can automatically drive the clamping plate 503 back to the initial open position under the contraction force of the second tension spring 502, preparing for the next loading and improving operating efficiency.

[0027] In addition, at least two sets of second tension springs 502 are provided to ensure even distribution of the reset force and prevent the sliding rod 501 from getting stuck during the reset process. At the same time, the second tension springs 502 can provide a continuous preload force when clamping.

[0028] As a preferred structure in this embodiment, a grinding assembly is provided on the top surface of the base plate 6. The grinding assembly includes a motor 901 and a grinding roller 902. The motor 901 is fixedly mounted on the top surface of the base plate 6, and the grinding roller 902 is fixedly mounted on the output shaft of the motor 901. The grinding roller 902 corresponds to the punching hole 402.

[0029] Burrs and sharp flash often appear on the edges of punched holes, affecting not only appearance but also posing safety hazards during subsequent handling and installation. This device, by setting up a grinding roller 902 corresponding to the punched hole 402, can uniformly chamfer or deburr the hole opening immediately after punching, ensuring a smooth and flat hole opening, improving the processing quality and safety of the workpiece.

[0030] To facilitate the collection of waste residue from punching and grinding, a bottom shell 9 for receiving waste is fixed on the top surface of the bottom plate 6, and the motor 901 is inside the bottom shell 9.

[0031] In order to facilitate the grinding of the workpiece, in this embodiment, cylinders 7 are fixedly provided on both sides of the base plate 6, and the ends of the cylinders 7 are fixedly connected to the bottom surface of the work plate 4.

[0032] In practice, the cylinders 7 on both sides of the base plate 6 move synchronously, driving the work plate 4, the base 401, and the clamped workpiece to move smoothly downwards as a whole. As the work plate 4 descends, the edges of the holes that have just been punched on the workpiece come into contact with the high-speed rotating grinding roller 902, completing the deburring and chamfering of the hole circumferentially.

[0033] As a preferred structure in this embodiment, a receiving assembly is provided on one side of the cylinder 7. The receiving assembly includes an extension plate 8 fixedly disposed on the side wall of the base plate 6, a connecting block 804 fixedly disposed on the bottom of the working plate 4, and a sliding block 802 slidably disposed on the top of the base plate 6. The connecting block 804 and the sliding block 802 are connected by a support rod 803. One end of the support rod 803 is hinged to the connecting block 804, and the other end is hinged to the sliding block 802. A screw 801 is provided between the sliding rod 501 and the extension plate 8. One end of the screw 801 is rotatably connected to the sliding block 802, and the other end is screwed to the extension plate 8.

[0034] The receiving component supports the working plate 4 during punching, preventing the impact force from directly acting on the cylinder 7 and affecting its service life. When the hydraulic cylinder 101 punches, the screw 801 of the receiving component is adjusted to raise the sliding block 802 and its support rod 803 mechanism, pre-pressing the working plate 4 to provide rigid support.

[0035] It should be noted that the mounting frame 1 is equipped with a guide plate 201. The two sides of the guide plate 201 are slidably connected to the two opposite sides of the mounting frame, and the base 401 is fixedly installed at the bottom of the guide plate 201.

[0036] A guide plate 201, which is set inside the mounting frame 1 and slidably connected to the inner wall, provides a guide stroke for the punch head 301. This ensures that the punch head 301 remains absolutely perpendicular and aligned with the punching hole 402 on the base 401 during descent and ascent, guaranteeing the consistency of quality for each punch.

[0037] In addition, the guide plate 201 is symmetrically provided with a pressing assembly. The pressing assembly includes a pressing column 202 that is slidably connected to the guide plate 201, an abutment plate 204 that is fixedly set at the bottom of the pressing column 202, and a first tension spring 203 that is fitted on the upper end of the pressing column 202. One end of the first tension spring 203 is fixedly connected to the guide plate 201, and the other end is fixedly connected to the top of the pressing column.

[0038] By means of symmetrical clamping components set on guide plate 201, the abutment plate 204 first clamps the workpiece surface under the action of the first tension spring 203 just before the stamping head 301 contacts the workpiece. Stamping is carried out according to the working sequence of clamping first and then stamping, ensuring that the workpiece and the base 401 are tightly fitted during stamping.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
