Description

Technical Field

[0001] The utility model belongs to the technical field of fish belly beam production, and particularly relates to an anti-injury device for processing a fish belly beam flange. Background Art

[0002] The fish belly beam has high bending strength, with a large middle cross-section that gradually decreases towards both ends of the beam. It can be used as a lower side beam in structures such as locomotives and carriages.

[0003] Fishbelly beams typically use I-beams as the processing material. The material is sequentially transferred to different processing stations, where it undergoes operations such as fishbelly cutting, cutting and pressing, seam welding, weld root cleaning, flange processing, and structural adjustment. Flange processing involves cutting the flanges on one side of the material. During the cutting process, the material is placed on its side, with the flanges at the bottom supported flat on the workbench. After the material is stably positioned, the laser cutting machine then processes the flanges at the top vertically to prevent deformation during cutting. Furthermore, due to the laser's high penetrating power, the laser can easily penetrate the flanges at the top and accidentally damage the flanges at the bottom, causing quality issues.

[0021] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0022] like Figure 1-Figure 5 As shown, a device for preventing injuries during the processing of fish-belly beam flanges comprises a cutting base 1, a clamping mechanism 2, and a lifting guide assembly 3. The cutting base 1 is provided with multiple clamping mechanisms 2 arranged in sequence along the material conveying direction. The clamping mechanisms 2 comprise a clamping platform 21 and a clamping assembly mounted on the clamping platform 21. The lifting guide assembly 3 is mounted on one side of the clamping platform 21. A blocking mechanism 4 is mounted on the clamping platform 21 at the end of the cutting base 1 on the side opposite the lifting guide assembly 3. The clamping assembly is also provided with an injury prevention mechanism 5.

[0023] During the process of material transmission to the flange processing station, the jacking guide assembly 3 provides auxiliary support and transmission guidance for the material. After the material is transmitted to the right place, the blocking mechanism 4 works to block the end of the material and stop the material transmission. Then the jacking guide assembly 3 lifts the material so that the material corresponds to the clamping assembly. Then the clamping assembly works to clamp the web of the material to complete the positioning of the material. At the same time, the clamping assembly drives the anti-injury mechanism 5 to move to the bottom of the wing plate at the top of the material, so that the anti-injury mechanism 5 blocks the wing plate at the bottom of the material, and then the laser cutting machine is used to process the wing plate at the top of the material. The material is stably clamped by the clamping mechanism to prevent the material from being cut and deformed during the processing. During the processing, the laser penetrates the wing plate at the top of the material and directly acts on the anti-injury mechanism 5, thereby preventing the laser from accidentally injuring the wing plate at the bottom of the material under the blocking of the anti-injury mechanism 5.

[0024] like Figure 2 As shown, the lifting guide assembly 3 includes a worm gear lift 31, a mounting plate 32, and a guide roller 33. The worm gear lift 31 is mounted on the side wall of the clamping platform 21. The mounting plate 32 is fixed to the output end of the worm gear lift 31, and the guide roller 33 is mounted on the mounting plate 32. The clamping assembly includes a clamping cylinder 22, a slide rail 23, a first slide 24, a second slide 25, and a clamping steel pipe 26. Slide rails 23 are fixed at both ends of the top of the clamping platform 21. The first slide 24 and the second slide 25 are arranged opposite to each other and slide on the slide rails 23 at both ends of the clamping platform 21 respectively. A clamping cylinder 22 is installed on the clamping platform 21 between the first slide 24 and the second slide 25. The two clamping cylinders 22 correspond to the first slide 24 and the second slide 25 respectively. The bottom of the first slide 24 and the bottom of the second slide 25 are fixedly connected to the output ends of the corresponding clamping cylinders 22. A clamping steel pipe 26 is fixed on the opposite side of the first slide 24 and the second slide 25. The two clamping steel pipes 26 are arranged opposite to each other, and an anti-injury mechanism 5 is provided on the top of the opposite ends of the two clamping steel pipes 26.

[0025] During material transmission, the material is supported on the guide rollers 33 and then guided by the guide rollers 33. When the material is in place, the blocking mechanism 4 blocks the material, stopping the material transmission. Then, the worm gear elevator 31 drives the mounting plate 32 upward, and the guide rollers 33 lift the material so that the material is aligned with the clamping steel pipe 26. Then, the clamping cylinder 22 connected to the first slide 24 stops working, keeping the first slide 24 fixed. The clamping cylinder 22 connected to the second slide 25 operates, driving the second slide 25 to slide along the slide rail 23 toward the first slide 24, thereby causing the two clamping steel pipes 26 to clamp the web of the material, completing the stable positioning of the material. At the same time, the damage prevention mechanism 5 is located below the top wing of the material, and the bottom wing of the material is blocked by the damage prevention mechanism 5. The position of the material can be adjusted by the operation of the two clamping cylinders 22 so that the top wing of the material corresponds to the processing position. When the material processing is completed, the clamping mechanism 2 releases the clamping of the material, and then the jacking guide component 3 lowers the material, and at the same time the blocking mechanism 4 releases the blocking of the material, so that the material can continue to be transported.

[0026] Since the output end of the clamping oil cylinder 22 has a certain amount of natural expansion and contraction when not working, that is, it will still expand and contract to a certain extent under the action of external force, so when the second slide 25 slides toward the first slide 24 until the two clamping steel pipes 26 clamp the material web, the output end of the clamping oil cylinder 22 connected to the first slide 24 will move under the action of external force, thereby causing the first slide 24 to move and fail to rigidly clamp the material, resulting in misalignment of the processing position of the material. In order to avoid this problem, the utility model is further provided with a baffle 6 and a support frame 7 at one end of the clamping table 21, such as Figure 2 As shown, the baffle 6 is fixed on the side opposite to the first slide 24 and the second slide 25, and a cylinder 8 is installed on the support frame 7. The output end of the cylinder 8 is vertically downward and fixedly connected to the positioning shaft 9. When the material is clamped and positioned, the cylinder 8 can drive the positioning shaft 9 to move downward so that the positioning shaft 9 is located between the baffle 6 and the first slide 24, and then the clamping cylinder 22 drives the first slide 24 to move toward the positioning shaft 9, and then the first slide 24 is pushed against the positioning shaft 9 until the two ends of the positioning shaft 9 are respectively in contact with the baffle rod 49 and the first slide 24, and then the clamping cylinder 22 drives the second slide 25 to move, so that the clamping steel pipe 26 on the second slide 25 is pushed against the clamping steel pipe 26 on the first slide 24. Under the rigid resistance of the fixed shaft, the second slide 25 can be prevented from moving further, thereby achieving rigid clamping of the material.

[0027] like Figure 3 、 4As shown, the injury prevention mechanism 5 includes a support plate 51, a pressure plate 52, a protective plate 53, a fixing rod 54, and a spring 55. There are multiple pressure plates 52, and the support plate 51 is placed flat and fixed on the clamping steel pipe 26. The multiple pressure plates 52 are arranged in parallel along the length direction of the support plate 51. The pressure plate 52 has an L-shaped structure. The horizontal section of the pressure plate 52 is fixed to the support plate 51, and the vertical section of the pressure plate 52 is parallel to the plate surface of the support plate 51. The protective plate 53 and the fixing rod 54 are provided between the vertical section of the pressure plate 52 and the support plate 51. One end of the fixing rod 54 is fixed to the horizontal section of the pressure plate 52, and the other end of the fixing rod 54 is slidably connected to the protective plate 53. The fixing rod 54 is sleeved with a spring 55, and the two ends of the spring 55 are respectively in contact with the horizontal section of the pressure plate 52 and the protective plate 53.

[0028] When the clamping steel pipe 26 moves to clamp the material web, the clamping steel pipe 26 drives the support plate 51 to abut against the material web, and at the same time the material web pushes against the protective plate 53. Under the action of the spring 55, the protective plate 53 and the material web are kept in abutment. When the laser cutting machine cuts the top wing plate of the material, the laser passes through the wing plate at the top of the material and acts on the protective plate 53, thereby preventing the laser from accidentally damaging the wing plate at the lower end of the material. When the protective plate 53 is damaged after repeated use, the protective plate 53 can be directly pulled out from the fixing rod 54 and then replaced.

[0029] like Figure 5 As shown, the blocking mechanism 4 includes a side plate 41, a top plate 42, a lifting cylinder 43, a connecting ear 44, a support 45, a rotating shaft 46, a connecting pin 47, a connecting rod 48, and a blocking rod 49. There are two side plates 41, which are upright and fixed in parallel to the side walls of the clamping platform 21. The two ends of the top plate 42 are respectively fixed to the tops of the two side plates 41. The lifting cylinder 43 is installed between the two side plates 41 below the top plate 42. The output end of the lifting cylinder 43 is fixed with a connecting ear 44, and the two ends of the top plate 42 are fixed with a support 45. The support 45 is provided with a rotating shaft 46, and the rotating shaft 46 is fixedly connected to the blocking rod 49. A through hole is provided in the middle of the top plate 42, and the connecting ear 44 can pass through the through hole. One end of the connecting rod 48 is fixedly connected to the rotating shaft 46, and the other end of the connecting rod 48 passes through the through hole and is rotatably connected to the connecting pin 47. A guide hole is provided on the connecting ear 44, and the connecting pin 47 passes through the guide hole and is slidably connected to the guide hole.

[0030] When the output end of the jacking oil cylinder 43 drives the connecting ear 44 to move up and down, the connecting pin 47 slides along the guide hole, and at the same time, the connecting pin 47 pushes the connecting rod 48, causing the connecting rod 48 to drive the rotating shaft 46 to rotate, and then drives the blocking rod 49 to rotate through the rotating shaft 46. When the material is transferred to the right position, the jacking oil cylinder 43 works, driving the blocking rod 49 to rotate to the upright state, and then the blocking rod 49 blocks the end of the material to stop the material from being transferred; the jacking oil cylinder 43 works, driving the blocking rod 49 to rotate to the horizontal state, and then the obstruction to the material can be released, so that the material can continue to be transferred. In this embodiment, the jacking oil cylinder 43 is in the following state. Figure 5 In the retracted state shown, the blocking rod 49 is in an upright state. When the lifting cylinder 43 drives the connecting ear 44 to rise, it can drive the blocking rod 49 to rotate to a horizontal state.
