Description

Technical Field

[0001] This utility model relates to the field of seamless tube cold drawing technology, and in particular to a seamless tube cold drawing device for a ship container anti-wind and wave hull binding bridge. Background Technology

[0002] A lashing bridge is a specially constructed steel frame or platform on the deck of a container ship (especially between hatch covers, on hatch covers, or on top of the hatch coaming). The main structural frame of the lashing bridge is welded from high-strength seamless steel pipes. A cooling device is required for processing the seamless pipes during fabrication.

[0003] During cold drawing, one end of the seamless tube is flattened (also known as tube tipping), and then stretched through a die with the correct inner diameter. When the process is complete, the outer diameter of the tube matches the inner diameter of the die. However, after prolonged use, the die will be damaged due to various reasons such as abrasive wear, adhesive wear, fatigue wear, and corrosive wear. Once the die is damaged, it needs to be replaced as a whole, which results in high usage costs. Utility Model Content

[0004] The purpose of this utility model is to provide a seamless tube cold drawing device for the rigging bridge of a ship container anti-wind and wave hull, which can replace the damaged parts of the mold and reduce the cost of use.

[0005] To achieve the above objectives, a cold-drawing device for seamless tubes used in the lashing of ship container hulls against wind and waves is provided. The device includes a seamless tube body and an mounting frame. Two drive shafts are symmetrically arranged within the mounting frame, with both ends of each shaft passing through and rotatably connected to the frame. A sprocket is fitted onto the surface of each drive shaft. Two sliding rods are symmetrically fixedly connected to the top of the mounting frame, perpendicular to the drive shafts. A pulling mechanism is located above the mounting frame, with the sliding rods passing through and slidably connected to the pulling mechanism. A drive chain is provided on the surface of each sprocket, and the drive chain is connected to the sprocket. The transmission chain is rotatably connected to both ends of the pulling mechanism. A mold mechanism is fixedly connected to the upper end of the mounting frame, located at the center of one end of the mounting frame. A gear reducer and a motor are located on one side of the mounting frame. The output shaft of the gear reducer is fixedly connected to the transmission shaft via a coupling. The motor shaft is fixedly connected to the input shaft of the gear reducer via a coupling. One end of the seamless tube body is flattened and passes through the mold mechanism, and the flattened end of the seamless tube body is clamped by the pulling mechanism. Support legs are fixedly connected to the four corners of the lower end of the mounting frame. This allows for the replacement of damaged parts of the mold, reducing operating costs.

[0006] The mold mechanism consists of a first mold, a base, a second mold, a fixing screw, and a third mold. The base is fixedly connected to the mounting frame. Three equidistant sliding grooves are provided at the top of the base, extending through one side of the base. Fixing blocks are fixedly connected to the bottom of the first, second, and third molds, and these fixing blocks are slidably connected to the sliding grooves. The first, second, and third molds are sequentially positioned in the three sliding grooves via the fixing blocks, with the first mold positioned at the end of the second mold furthest from the pulling mechanism. The seamless tube body passes sequentially through the middle of the first, second, and third molds. The fixing screw is located at one end of the base, extending through both the base and the fixing block, and fixes the fixing block within the base. The first, second, and third molds, together with the base, form a complete cold-drawing mold. The fixing screw secures the first, second, and third molds mounted on the base via the fixing blocks.

[0007] The inner diameter of the central channel in the first, second, and third molds gradually decreases, forming a frustum shape. This causes the diameter of the seamless tube body passing through to gradually decrease.

[0008] The clamping mechanism consists of an adjusting screw, guide posts, a base plate, a clamping mechanism, a mounting frame, a pressure plate, a sliding block, and a clamping block. The base plate is located above the mounting frame. The two ends of the transmission chain are rotatably connected to the two sides of the mounting frame, respectively. The sliding block is fixedly connected to the lower end of the base plate, and a sliding rod passes through the middle of the sliding block and is slidably connected to the sliding block. The clamping mechanism and the mounting frame are both fixedly connected to the upper end of the base plate, and the mounting frame is located on the side of the clamping mechanism away from the mold mechanism. The mounting frame has a U-shaped structure. The pressure plate is located in the mounting frame, and the lower end of the pressure plate cooperates with the bottom of the mounting frame to clamp the flattened end of the seamless tube body. The adjusting screw is located at the upper end of the mounting frame, and the lower end of the adjusting screw passes through the mounting frame and is threadedly connected to the mounting frame. The lower end of the adjusting screw is rotatably connected to the middle of the upper end of the pressure plate. The guide posts are fixedly connected to the two sides of the mounting frame, and the guide posts pass through the pressure plate and are slidably connected to the pressure plate. The adjusting screw rotates to push the pressure plate down, which, together with the mounting bracket, clamps the flat end of the seamless tube body from the top and bottom. The clamping mechanism clamps the left and right sides of the seamless tube body.

[0009] The clamping mechanism consists of clamping blocks, a guide rail, a handwheel, a double-acting screw, and sliding blocks. The guide rail is fixedly connected to the upper end of the base plate. The double-acting screw is located in the middle of the guide rail and passes through it, rotatably connecting to the guide rail. The handwheel is fixedly connected to one end of the double-acting screw. Two sliding blocks are provided and symmetrically arranged in the guide rail, with the double-acting screw passing through the middle of each sliding block. The two sliding blocks are located in the two threaded directions of the double-acting screw. The clamping blocks are fixedly connected to the upper ends of the sliding blocks, and the clamping blocks at the upper ends of the two sliding blocks cooperate to clamp the two sides of the seamless tube body. The handwheel controls the rotation of the double-acting screw, causing the sliding blocks to move the clamping blocks closer together, thus clamping the seamless tube body.

[0010] The inner wall of the mounting frame, the bottom of the pressure plate, and the surface of the clamping block are all provided with anti-slip protrusions. This increases the friction between the inner wall of the mounting frame, the bottom of the pressure plate, and the surface of the clamping block.

[0011] The beneficial effects of this utility model are: The first, second, and third molds, together with the base, form a complete cold drawing mold. The fixing screws fix the first, second, and third molds installed on the base through the fixing blocks, so that the worn parts in the mold mechanism can be replaced individually, reducing the cost of use.

Detailed Implementation

[0019] Reference Figure 1-6 This utility model discloses a seamless tube cold-drawing device for lashing bridges of ship container anti-wind and wave hulls. It includes a seamless tube body 1 and a mounting frame 4. Two drive shafts 11 are symmetrically arranged in the mounting frame 4, with both ends of each shaft 11 passing through and rotatably connected to the mounting frame 4. A sprocket 10 is sleeved on the surface of each drive shaft 11. Two sliding rods 3 are symmetrically fixedly connected to the top of the mounting frame 4, and the sliding rods 3 are perpendicular to the drive shafts 11. A pulling mechanism 7 is provided above the mounting frame 4, and the sliding rods 3 pass through and are slidably connected to the pulling mechanism 7. A drive chain 9 is provided on the surface of each sprocket 10. Engaging with sprocket 10, the two ends of transmission chain 9 are rotatably connected to the two ends of pulling mechanism 7 respectively. The upper end of mounting frame 4 is fixedly connected to mold mechanism 2, and mold mechanism 2 is located in the middle of one end of mounting frame 4. A gear reducer 5 and a motor 6 are provided on one side of mounting frame 4. The output shaft of gear reducer 5 is fixedly connected to transmission shaft 11 through coupling. The rotating shaft of motor 6 is fixedly connected to input shaft of gear reducer 5 through coupling. One end of seamless tube body 1 is flattened and passes through mold mechanism 2. The flattened end of seamless tube body 1 is clamped by pulling mechanism 7. Support legs 8 are fixedly connected to the four corners of the lower end of mounting frame 4.

[0020] The mold mechanism 2 consists of a first mold 12, a base 13, a second mold 15, a fixing screw 16, and a third mold 17. The base 13 is fixedly connected to the mounting frame 4. Three sliding grooves 14 are provided at equal intervals at the top of the base 13, and the sliding grooves 14 pass through one side of the base 13. The bottom of the first mold 12, the second mold 15, and the third mold 17 are all fixedly connected to fixing blocks 18, and the fixing blocks 18 are slidably connected to the sliding grooves 14. The first mold 12, the second mold 15, and the third mold 17 are sequentially arranged in the three sliding grooves 14 through the fixing blocks 18, and the first mold 12 is located at the end of the second mold 15 away from the pulling mechanism 7. The seamless tube body 1 passes through the middle of the first mold 12, the second mold 15, and the third mold 17 in sequence. The fixing screw 16 is located at one end of the base 13, and the fixing screw 16 passes through the base 13 and the fixing block 18, and the fixing screw 16 fixes the fixing block 18 in the base 13. The first mold 12, the second mold 15, and the third mold 17, together with the base 13, form a complete cold drawing mold. The fixing screw 16 fixes the first mold 12, the second mold 15, and the third mold 17 installed on the base 13 through the fixing block 18.

[0021] The inner diameter of the central channel in the first mold 12, the second mold 15, and the third mold 17 gradually decreases and forms a frustum shape. This causes the diameter of the seamless tube body 1 passing through to gradually decrease.

[0022] The clamping mechanism 22 consists of an adjusting screw 19, a guide post 20, a base plate 21, a clamping mechanism 22, a mounting bracket 23, a pressure plate 24, a sliding block 25, and a clamping block 26. The base plate 21 is located above the mounting frame 4. The two ends of the transmission chain 9 are rotatably connected to the two sides of the mounting frame 4, respectively. The sliding block 25 is fixedly connected to the lower end of the base plate 21, and the sliding rod 3 passes through the middle of the sliding block 25 and is slidably connected to the sliding block 25. The clamping mechanism 22 and the mounting bracket 23 are both fixedly connected to the upper end of the base plate 21, and the mounting bracket 23 is located on the clamping mechanism 22. On the side away from the mold mechanism 2, the mounting frame 23 has a U-shaped structure. A pressure plate 24 is located within the mounting frame 23, and its lower end engages with the bottom of the mounting frame 23 to clamp the flattened end of the seamless tube body 1. An adjusting screw 19 is located at the upper end of the mounting frame 23, with its lower end passing through the mounting frame 23 and threadedly connected to it. The lower end of the adjusting screw 19 is rotatably connected to the middle of the upper end of the pressure plate 24. Guide posts 20 are fixedly connected to both sides of the mounting frame 23, and they pass through the pressure plate 24 and are slidably connected to it. Rotating the adjusting screw 19 pushes the pressure plate 24 downwards, cooperating with the mounting frame 23 to clamp the flattened end of the seamless tube body 1 from top to bottom. The clamping mechanism 22 clamps the left and right sides of the seamless tube body 1.

[0023] The clamping mechanism 22 consists of clamping blocks 26, guide rails 27, handwheels 28, bidirectional lead screws 29, and sliders 30. Guide rails 27 are fixedly connected to the upper end of the base plate 21. The bidirectional lead screw 29 is located in the middle of guide rails 27, passing through and rotatably connected to them. Handwheels 28 are fixedly connected to one end of the bidirectional lead screw 29. Two sliders 30 are provided and symmetrically arranged in the guide rails 27, with the bidirectional lead screw 29 passing through the middle of each slider 30. The two sliders 30 are located in the two threaded directions of the bidirectional lead screw 29. Clamping blocks 26 are fixedly connected to the upper ends of the sliders 30, and the clamping blocks 26 at the upper ends of the two sliders 30 cooperate to clamp both sides of the seamless tube body 1. Handwheels 28 control the rotation of the bidirectional lead screw 29, causing the sliders 30 to move the clamping blocks 26 closer together, thus clamping the seamless tube body 1.

[0024] Anti-slip protrusions are provided on the inner wall of the mounting bracket 23, the bottom of the pressure plate 24, and the surface of the clamping block. This increases the friction between the inner wall of the mounting bracket 23, the bottom of the pressure plate 24, and the surface of the clamping block.

[0025] Working principle: Before cold pressing the seamless tube, the pulling mechanism 7 contacts the mold mechanism 2, then flattens one end of the seamless tube body 1, and passes the flattened end through the mold mechanism 2 into the mounting frame 23. By rotating the adjusting screw 19, the pressure plate 24 is lowered to clamp the flat end of the seamless tube body 1. Then, by rotating the handwheel 28, the double-acting screw 29 is rotated, causing the slider 30 to drive the clamping blocks 26 to move closer to each other to clamp the surface of the seamless tube body 1. The motor 6 drives the transmission shaft 11 to rotate through the gear reducer 5, causing the sprocket 10 to pull the pulling mechanism 7 away from the mold mechanism 2 through the transmission chain 9, thereby cold drawing the seamless tube body 1. When replacing the worn structure in the mold mechanism 2, the fixing screw 16 is removed from the base 13, and then the worn first mold 12, second mold 15 or third mold 17 is removed and replaced by sliding the fixing block 18 and the slide groove 14.
