Description

Technical Field

[0001] The invention relates to the technical field of bending ship accessories, and more specifically, to a bending device used for processing ship accessories. Background Art

[0002] Ship accessories refer to various parts and equipment used in ship construction, maintenance and operation, including hull plates, decks, hatch covers, ribs, window frames and other ship accessories. To manufacture ship window frames, the aluminum material must first be cut and punched, then bent, and finally welded. The bending of ship window frames usually involves placing the material on a bending machine, adjusting the mold and pressure of the bending machine, and performing the bending operation to ensure that the bending angle and shape meet the design requirements.

[0003] In order to ensure the position and size accuracy of the holes on the window frame, it is usually necessary to drill holes first and then bend them. When the holes on the ship window are very close to the bending line, the holes close to the bending line will be deformed when the window frame is bent, resulting in the inability to align the two ends of the bent aluminum material, thereby affecting the subsequent window frame welding and assembly.

[0004] When external force acts on the aluminum to bend it, the aluminum will undergo plastic deformation and form a permanent bent shape. However, due to the elastic properties of the aluminum, the material will try to return to its original state after the external force is removed. This recovery of elastic deformation leads to the so-called elastic reaction or springback phenomenon. Due to the elastic reaction, the size and shape of the bent aluminum may deviate from the size and shape of the mold, affecting the accuracy of the parts and causing the parts to be unable to be used normally, making it impossible for the two ends of the aluminum to fit together, affecting the subsequent welding of the two ends.

[0005] Therefore, it is necessary to design a ship fitting bending device that can prevent the elastic deformation of aluminum and the deformation of the internal holes of aluminum to improve the above-mentioned technical problems. Summary of the invention

[0050] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0051] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0052] For example, see Figure 1-14 The present invention provides the following technical solutions: A bending device for processing ship accessories, comprising a work table 1, a clamping mechanism 2 for clamping and conveying aluminum materials is provided on the upper side of the work table 1, a bending mechanism 3 for bending the aluminum materials is provided on one side of the clamping mechanism 2, and a bulletproof mechanism 4 for limiting the bent aluminum materials and indirectly cleaning the oil on the pressing surface of the aluminum materials is provided on one side of the bending mechanism 3.

[0053] See also Figure 2 The clamping mechanism 2 includes an electric slide rail 21 fixedly connected to the upper side of the work table 1 , a sliding end of the electric slide rail 21 is fixedly connected to a support frame 22 , and a clamping claw 23 is fixedly connected to one side of the support frame 22 .

[0054] Specifically, the clamping claw 23 is used to clamp one end of the aluminum material, and the movement of the sliding end of the electric slide rail 21 is used to drive the aluminum material to move, so that the bending mechanism 3 bends the four areas of the aluminum material in sequence.

[0055] See also Figure 3 The bending mechanism 3 includes a support assembly 31 arranged on the upper side of the work table 1, a rotating assembly 32 is provided on the lower side of the support assembly 31, a limiting assembly 35 is provided inside the support assembly 31, and a sliding guide assembly 33 and a clamping assembly 34 are respectively provided on one side of the support assembly 31.

[0056] Specifically, the support assembly 31 is used to support the rotating assembly 32, the limiting assembly 35, the guide sliding assembly 33 and the clamping assembly 34; the rotating assembly 32 is used to control the rotation of the limiting assembly 35 and the clamping assembly 34 so as to bend the aluminum material; the guide sliding assembly 33 is used to guide the sliding of the aluminum material; and the clamping assembly 34 is used to press the aluminum material against the surface of the limiting assembly 35.

[0057] See also Figure 4 The support assembly 31 includes a second support plate 314 fixedly connected to the upper side of the work table 1, the upper side of the second support plate 314 is fixedly connected to the first support plate 312, the upper side of the first support plate 312 is fixedly connected to the second top plate 313, and the upper side of the second top plate 313 is fixedly connected to the first top plate 311.

[0058] See also Figure 5 The rotating assembly 32 includes a rotating motor 321 fixedly connected to the lower side of the first supporting plate 312 , and the output end of the rotating motor 321 is fixedly connected to the first gear 322 .

[0059] Specifically, the rotation of the output end of the rotating motor 321 is used to control the rotation of the first gear 322 , thereby controlling the rotation of the second gear 351 , and further controlling the rotation of the rotating shaft 353 .

[0060] See also Figure 6 The guide sliding assembly 33 includes a first cylinder 331 fixedly connected to the lower side of the guide sliding assembly 33, the output end of the first cylinder 331 is fixedly connected to the first connecting plate 332, the upper side of the first connecting plate 332 is fixedly connected to the first guide rail 333, the upper side of the first guide rail 333 is slidably connected to the first slider 334, the upper side of the first slider 334 is fixedly connected to the first mounting plate 335, and one side of the first mounting plate 335 is fixedly connected to the first guide slider 336.

[0061] Specifically, the expansion and contraction of the output end of the first cylinder 331 is used to guide the sliding of aluminum materials of different widths. When the aluminum material moves, the first guide slide block 336 guides the sliding of the aluminum material.

[0062] See also Figure 7 The clamping assembly 34 includes an L-shaped plate 341 fixedly connected to the outer side of the rotating shaft 353, one side of the L-shaped plate 341 is fixedly connected to the second cylinder 342, the upper side of the second cylinder 342 is fixedly connected to the second guide rail 343, the output end of the second cylinder 342 is fixedly connected to the second connecting plate 344, one side of the second connecting plate 344 is fixedly connected to the second slider 345, the second slider 345 is slidably connected to the second guide rail 343, the upper side of the second slider 345 is fixedly connected to the second mounting plate 346, and one side of the second mounting plate 346 is fixedly connected to the clamping block 347.

[0063] Specifically, the extension and retraction of the output end of the second cylinder 342 is used to control the movement of the pressing block 347, thereby pressing the aluminum material.

[0064] When the clamp 23 clamps the aluminum material, the sliding end of the electric slide rail 21 slides and drives the aluminum material to move. When the aluminum material reaches one side of the clamping block 347, the output end of the second cylinder 342 retracts, and the clamping block 347 presses the aluminum material on the surface of the U-shaped limit block 352. The output end of the rotating motor 321 rotates, driving the clamping block 347 and the U-shaped limit block 352 to rotate. The sliding end of the electric slide rail 21 drives the aluminum material to continue to move, thereby bending an area of ​​the aluminum material. The methods for the subsequent three bendings are the same as the method for the first bending of the aluminum material mentioned above, and will not be repeated here.

[0065] Embodiment 2: In order to ensure the position and size accuracy of the holes on the window frame, it is usually necessary to drill holes first and then bend them. When the holes on the ship window are very close to the bending line, the holes close to the bending line will be deformed when the window frame is bent, resulting in the inability to align the two ends of the bent aluminum material, thereby affecting the subsequent welding and assembly of the window frame. Therefore, the following structure is designed to solve the above technical problems.

[0066] See also Figure 7 The limiting assembly 35 includes a rotating shaft 353 whose bearings are connected to the first top plate 311 and the first support plate 312, a second gear 351 is fixedly connected to the outer side of the rotating shaft 353, the second gear 351 is chain-connected to the first gear 322, a U-shaped limiting block 352 is provided on the upper side of the first top plate 311 and the U-shaped limiting block 352 is fixedly connected to the rotating shaft 353, a positioning plate 354 is provided on the upper side of the U-shaped limiting block 352 and the positioning plate 354 is fixedly connected to the rotating shaft 353, a third cylinder 355 is fixedly connected to one side of the positioning plate 354, and a blocking column 356 is fixedly connected to the output end of the third cylinder 355.

[0067] Specifically, in the initial state, the output end of the third cylinder 355 is in a fully retracted state. When the aluminum material is compressed by the clamping block 347, the output end of the third cylinder 355 extends out, and the blocking column 356 passes through the avoidance hole set inside the clamping block 347, and extends into the hole inside the plate to block the hole inside the plate. The output end of the rotating motor 321 rotates, driving the clamping block 347 and the U-shaped limit block 352 to rotate, and the sliding end of the electric slide rail 21 drives the aluminum material to continue to move, thereby bending an area of ​​the aluminum material. The blocking column 356 is driven by the positioning plate 354 to rotate. When an area of ​​the aluminum material is bent, the output end of the third cylinder 355 retracts and the blocking column 356 returns to its position.

[0068] By blocking the holes near the bending line before bending the aluminum material, the holes near the bending line are effectively prevented from deforming when the window frame is bent, and the two ends of the aluminum material after bending are avoided from being unable to align, thus achieving a high bending accuracy effect.

[0069] Embodiment 3: When external force acts on the aluminum material to bend it, the aluminum material will undergo plastic deformation to form a permanent bent shape. However, due to the elastic properties of the aluminum material, after the external force is removed, the material will try to return to its original state. This recovery of elastic deformation leads to the so-called elastic reaction or springback phenomenon. Due to the elastic reaction, the size and shape of the bent aluminum material may deviate from the size and shape of the mold, affecting the accuracy of the parts and causing the parts to be unable to be used normally, thereby making it impossible for the two ends of the aluminum material to fit together, affecting the subsequent welding of the two ends. Therefore, the following structure is designed to solve the above technical problems.

[0070] See also Figure 8 The bulletproof mechanism 4 includes a third guide rail 41 fixedly connected to the upper side of the work table 1, a side plate 46 is fixedly connected to one side of the third guide rail 41, a fourth cylinder 44 is fixedly connected to one side of the side plate 46, an output end of the fourth cylinder 44 passes through the side plate 46 and is fixedly connected to a third connecting block 45, a third slider 42 is fixedly connected to one side of the third connecting block 45, and the third slider 42 is slidably connected to the third guide rail 41, and a bulletproof component 43 is provided on the upper side of the third slider 42.

[0071] Specifically, the extension and retraction of the output end of the fourth cylinder 44 is used to control the bulletproof block 431 to move along the third guide rail 41, so that the bulletproof block 431 is close to or away from the bent edge of the aluminum material after bending.

[0072] See also Fig. 9 The bulletproof component 43 includes a bulletproof block 431 fixedly connected to the upper side of the third slider 42, two gear boxes 432 are fixedly connected to the two sides of the bulletproof block 431, a limiting groove is provided on one side of the bulletproof block 431, a slide groove 434 is provided on one side of the limiting groove, and cloth passing grooves 433 are provided on both sides of the slide groove 434, and the cloth passing grooves 433 are trapezoidal.

[0073] Specifically, after the aluminum material is bent, the output end of the fourth cylinder 44 extends out to control the bulletproof block 431 to approach the bent aluminum material until the limit groove of the bulletproof block 431 completely holds the bent aluminum material, the output end of the fourth cylinder 44 stops extending, the output end of the first cylinder 331 extends out, the output end of the second cylinder 342 extends out, the first guide slider 336 and the clamping block 347 are driven to move and move away from the aluminum material, at this time the aluminum material is no longer clamped, the sliding end of the electric slide rail 21 drives the aluminum material to move until the reserved area allows the U-shaped limit block 352 to rotate back to its original position, the sliding end of the electric slide rail 21 stops moving, the output end of the rotating motor 321 rotates to control the clamping block 347 and the U-shaped limit block 352 to return, while the output end of the fourth cylinder 44 retracts to control the movement of the bulletproof block 431 to return, at this time the elastic stress of the aluminum material has disappeared, no rebound phenomenon occurs, and the aluminum material can be bent again for the next time.

[0074] After the aluminum material is bent, the fourth cylinder 44 controls the bulletproof block 431 to press the bent edge, and when the clamping block 347 and the U-shaped limit block 352 return, the bulletproof block 431 returns at the same time, thereby extending the time of pressing the bent edge of the aluminum material, effectively preventing the aluminum material from rebounding after bending and the two ends of the aluminum material from being unable to fit together, thereby achieving a high bending accuracy of the aluminum material.

[0075] Embodiment 4: Usually when the aluminum material is bent, in order to reduce the wear of the contact surface between the clamping assembly 34 and the aluminum material and extend the service life of the clamping assembly 34, the area where the aluminum material is clamped needs to be oiled. When the aluminum material is completely bent, there will be a large amount of oil stains on the surface of the aluminum material. The oil stains will adsorb most of the dust on the surface of the aluminum material, and during the welding process, the oil stains will decompose due to the high temperature and react with the aluminum material to generate hydrogen, resulting in defects such as welding porosity, which seriously affects the welding quality. Therefore, the following structure is designed to solve the above technical problems.
