Description

Technical Field

[0001] This utility model relates to the field of punching device technology, specifically a punching device for ship processing parts. Background Technology

[0002] Punching in shipbuilding parts manufacturing refers to the process of using equipment such as punch presses and dies to apply pressure to metal sheets or other materials, creating holes at specific locations. Punching plays a crucial role in ensuring the quality and performance of shipbuilding parts.

[0003] Patent publication number CN 217433103 U discloses a punching device for parts in ship forging. The technical solution includes: a fixed frame, a housing, and a base plate. A front housing is mounted on the top of the base plate. A pad is movably mounted on the bottom of the processing table. A hydraulic cylinder is mounted on a support frame via the fixed frame, and a drill bit is mounted through the bottom of the hydraulic cylinder through the fixed frame. Limit bolts are threaded on both sides of the fixed frame, and baffles are installed inside the limit bolts. A hydraulic pump is installed inside the housing.

[0004] To address the issue of component misalignment during machining, existing technology employs a method involving threaded limit bolts on both sides of a fixed frame, with baffles installed inside the limit bolts. An electric actuator adjusts the height of an auxiliary plate according to the machining table height, and the limit bolts are manually rotated to clamp the component using the baffles. This adjustment increases stability during machining. However, the baffles sometimes fail to deform sufficiently to clamp and punch components of different shapes, leading to inconvenience. Therefore, we propose a punching device for shipbuilding components. Utility Model Content

[0005] The purpose of this invention is to provide a punching device for ship processing parts to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A punching device for ship processing parts includes a worktable with support legs fixedly connected to the four corners of its bottom surface. The worktable has a hollow design, and a collection box is movably inserted into the cavity. A handle is fixedly connected to the side of the collection box away from the worktable. A clamping mechanism for fixing parts is provided in the middle of the upper surface of the worktable. An elastic component for clamping parts of different shapes is provided outside the clamping mechanism. A telescopic mechanism for pushing waste material into the collection box is also provided on the top surface of the worktable. A discharge port is provided through both sides of the top of the worktable. A punching device is provided on the top surface of the worktable away from the handle.

[0008] Preferably, the clamping mechanism includes two H-shaped fixing plates, the bottom ends of the two H-shaped fixing plates are respectively fixedly connected to the top surfaces of the two sides of the workbench, one side of one of the H-shaped fixing plates is fixedly connected to a first mounting plate, the upper surface of the first mounting plate is fixedly mounted with a rotating motor, and the output end of the rotating motor is fixedly connected to a bidirectional lead screw through the wall of the H-shaped fixing plate.

[0009] Preferably, a limiting rod is fixedly connected to the top of one side of the adjacent surfaces of the two H-shaped fixing plates, and the two ends of the bidirectional screw are respectively rotatably connected to the other side wall plate of the top of the adjacent surfaces of the two H-shaped fixing plates. Two sliding plates are installed on the bidirectional screw and the limiting rod. One end of the two sliding plates is threaded onto the bidirectional screw, and the other end of the two sliding plates is slidably sleeved onto the limiting rod. The bidirectional screw, the limiting rod and the two sliding plates are arranged in a rectangular shape.

[0010] Preferably, the elastic component includes a first splicing plate fixed to the adjacent surfaces of the middle of two sliding plates. The adjacent surfaces of the two first splicing plates are provided with a plurality of linearly arrayed circular holes. Springs are placed inside the plurality of linearly arrayed circular holes. A second splicing plate is movably fitted to the adjacent surfaces of the two first splicing plates. Threaded holes are also provided at the four corners of the adjacent surfaces of the two first splicing plates. A plurality of sliding pillars that cooperate with a plurality of springs are slidably sleeved on the upper part of the two second splicing plates. A limiting plate is fixedly connected to one end of each of the plurality of sliding pillars near the first splicing plate. The limiting plates are located in the plurality of linearly arrayed circular holes, and the side of the limiting plate away from the sliding pillar is fitted with the end of the spring near the second splicing plate.

[0011] Preferably, each of the four outer corners of the second splicing plate is rotatably connected with a threaded rod that engages with four threaded holes, and the ends of the four threaded rods away from the sliding column are threaded into the four threaded holes.

[0012] Preferably, the telescopic mechanism includes a second mounting plate fixedly connected to the top surface of the workbench on the side near the handle, and the second mounting plate is located at the top of the workbench away from the rotating motor. An electric telescopic rod is fixedly installed on the upper surface of the second mounting plate, and a scraper is fixedly connected to the telescopic end of the electric telescopic rod.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model, through the arrangement of sliding posts, springs, and circular holes, places the parts requiring punching between two second splicing plates. The output of a rotating motor drives a bidirectional lead screw to rotate, causing the two sliding plates to slide on a limiting rod. This brings the two second splicing plates closer together, where the sliding posts on the two splicing plates clamp and fix the parts. When clamping parts of different shapes, the sliding posts on both sides of the second splicing plates are subjected to compressive force, causing the springs to contract and the sliding posts to enter the circular hole. This changes the position of the sliding posts on the two second splicing plates, satisfying the need for wrapping, limiting, clamping, and fixing parts of different shapes, facilitating subsequent punching. By removing the threaded rod, the second splicing plate can be removed from the first splicing plate, allowing the spring inside the circular hole to be replaced, simplifying its use.

[0015] 2. This utility model, through the setting of an electric telescopic rod and a scraper, allows the scraper to move back and forth by activating the electric telescopic rod, which pushes the waste generated by punching parts on the workbench through the feeding port into the collection box. The collection box can be pulled out of the workbench by pulling the handle, so that the waste can be processed later. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5 As shown, a punching device for ship processing parts includes a workbench 1. Support legs 2 are fixedly connected to the four corners of the bottom surface of the workbench 1. The workbench 1 has a cavity design. A collection box 3 is movably inserted into the cavity of the workbench 1. A handle 4 is fixedly connected to the side of the collection box 3 away from the workbench 1. A clamping mechanism 6 for fixing parts is provided in the middle of the upper surface of the workbench 1. An elastic component 7 for clamping parts of different shapes is provided outside the clamping mechanism 6. A telescopic mechanism 8 for pushing waste material into the collection box 3 is also provided on the top surface of the workbench 1. A discharge port 5 is opened through both sides of the top of the workbench 1. A punching device 9 is provided on the top surface of the workbench 1 away from the handle 4.

[0025] In practice, the waste generated from punching parts is collected and dropped into the collection box 3 by using the feed port 5. After punching is completed, the collection box 3 can be pulled out from the workbench 1 by pulling the handle 4, so as to carry out subsequent processing of the waste.

[0026] As a technical optimization of this utility model, the clamping mechanism 6 includes two H-shaped fixing plates 61. The bottom ends of the two H-shaped fixing plates 61 are respectively fixedly connected to the top surfaces of the two sides of the workbench 1. A first mounting plate 62 is fixedly connected to one side of one of the H-shaped fixing plates 61. A rotary motor 63 is fixedly installed on the upper surface of the first mounting plate 62. The output end of the rotary motor 63 passes through the plate wall of the H-shaped fixing plate 61 and is fixedly connected to a bidirectional lead screw 64. A limit rod 65 is fixedly connected to the top of one side of the adjacent surface of the two H-shaped fixing plates 61. The two ends of the bidirectional lead screw 64 are respectively rotatably connected to the other side wall of the top of the adjacent surface of the two H-shaped fixing plates 61. Two sliding plates 66 are installed on the bidirectional lead screw 64 and the limit rod 65. One end of the two sliding plates 66 is threaded onto the bidirectional lead screw 64, and the other end of the two sliding plates 66 is slidably sleeved onto the limit rod 65. The bidirectional lead screw 64, the limit rod 65 and the two sliding plates 66 are arranged in a rectangle.

[0027] In practice, the component is placed between two sliding plates 66. The rotating motor 63 is started, and the output end of the rotating motor 63 drives the bidirectional lead screw 64 to rotate. The rotation of the bidirectional lead screw 64 causes the two sliding plates 66 to slide on the limiting rod 65. The two sliding plates 66 move closer to each other, thereby clamping and fixing the component.

[0028] As a technical optimization of this utility model, the elastic component 7 includes a first splicing plate 71 fixed on the adjacent surfaces of two sliding plates 66 in the middle. The adjacent surfaces of the two first splicing plates 71 are provided with a plurality of linear array circular holes 72. Springs 73 are placed inside the plurality of linear array circular holes 72. The adjacent surfaces of the two first splicing plates 71 are movably fitted with a second splicing plate 75. Threaded holes 74 are also provided at the four corners of the adjacent surfaces of the two first splicing plates 71. A plurality of sliding posts 76 that cooperate with a plurality of springs 73 are slidably sleeved on the upper part of the two second splicing plates 75. A limiting plate 77 is fixedly connected to one end of the plurality of sliding posts 76 near the first splicing plate 71. The plurality of limiting plates 77 are located in the plurality of linear array circular holes 72, and the side of the limiting plate 77 away from the sliding posts 76 is fitted with the end of the spring 73 near the second splicing plate 75.

[0029] In practice, the parts requiring punching are placed between two second splicing plates 75. The output of the rotating motor 63 drives the bidirectional lead screw 64 to rotate. The rotation of the bidirectional lead screw 64 causes two sliding plates 66 to slide on the limiting rod 65, thereby bringing the two second splicing plates 75 closer together. The sliding posts 76 on the two second splicing plates 75 are used to clamp and fix the parts. When clamping parts of different shapes, the sliding posts 76 on the two second splicing plates 75 are subjected to compressive force, and the spring 73 contracts, causing the sliding posts 76 to enter the round hole 72. This changes the position of the sliding posts 76 on the two second splicing plates 75, satisfying the need to wrap, limit, clamp and fix parts of different shapes, facilitating subsequent punching and making it convenient to use.

[0030] As a technical optimization of this utility model, the four outer corners of the second splicing plate 75 are rotatably connected with threaded rods 78 that cooperate with four threaded holes 74, and the ends of the four threaded rods 78 away from the sliding column 76 are threadedly connected to the four threaded holes 74.

[0031] In practice, by removing the threaded rod 78, the second splicing plate 75 can be removed from the first splicing plate 71, and the spring 73 inside the round hole 72 can be replaced, which facilitates use.

[0032] As a technical optimization of this utility model, the telescopic mechanism 8 includes a second mounting plate 81 fixedly connected to the top surface of the workbench 1 near the handle 4, and the second mounting plate 81 is located at the top of the workbench 1 away from the rotating motor 63. An electric telescopic rod 82 is fixedly installed on the upper surface of the second mounting plate 81, and a scraper 83 is fixedly connected to the telescopic end of the electric telescopic rod 82. The lower end face of the scraper 83 abuts against the top surface of the workbench 1.

[0033] In practice, by activating the electric telescopic rod 82, the scraper 83 is moved back and forth by the telescopic end of the electric telescopic rod 82, which can push the waste generated by punching parts on the workbench 1 into the collection box 3 through the discharge port 5.

[0034] In use, this invention places the component requiring punching between two second splicing plates 75. The rotating motor 63 is then started, and its output drives a bidirectional lead screw 64 to rotate. The rotation of the lead screw 64 causes two sliding plates 66 to slide on the limiting rod 65, bringing the two second splicing plates 75 closer together. When the component is clamped, the sliding posts 76 on both sides of the second splicing plates 75 contact the component, causing the sliding posts 76 to be compressed. The spring 73 contracts, allowing the sliding posts 76 to enter the circular hole 72. The sliding posts 76 on the two second splicing plates 75 then wrap around, limit, clamp, and fix the component. Then, start the punching equipment 9 to complete the punching of the parts. After punching, the parts can be removed by rotating the output end of the motor 63 in the opposite direction to drive the bidirectional lead screw 64 to rotate in the opposite direction. Then, start the electric telescopic rod 82. The telescopic end of the electric telescopic rod 82 drives the scraper 83 to move back and forth, pushing the waste generated by punching the parts on the workbench 1 through the feed port 5 into the collection box 3. Pull the handle 4 to pull the collection box 3 out of the workbench 1 for further processing of the waste. When the spring 73 needs to be replaced, the second splicing plate 75 can be removed from the first splicing plate 71 by removing the threaded rod 78, and the spring 73 inside the round hole 72 can be replaced.

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