Description

Technical Field

[0001] The utility model relates to the technical field of section steel cutting machines, in particular to an automatic feeding device for a laser section steel cutting machine. Background Art

[0002] Section steel is a bar-shaped steel with a certain cross-sectional shape and size, and it is one of the four major types of steel (plate, pipe, section, wire). According to the cross-sectional shape, section steel is divided into simple cross-section section steel and complex cross-section section steel (special-shaped steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beam, channel steel, rail, window frame steel, bent section steel, etc.

[0003] Before use, section steel usually needs to be processed by a laser section steel cutting machine to complete processes such as cutting, punching, marking, and scribing, so that the section steel meets the use requirements. Existing laser section steel cutting machines usually process single-section steel. After processing, it is necessary to manually feed the next section steel into the chuck of the laser section steel cutting machine. When processing single-section steel, after cutting the section steel to the required length, waste materials are usually generated, causing certain waste. Moreover, the section steel is heavy, and manual feeding has great potential safety hazards and is easy to collide with the machine. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides an automatic feeding device for a laser section steel cutting machine.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: an automatic feeding device for a laser section steel cutting machine, including a frame arranged along the feeding direction of the laser section steel cutting machine. Along the length direction of the top of the frame, a number of bearing beams for placing section steel are arranged at intervals. A sliding frame is slidably arranged on the frame along the width direction of the frame. A number of bearing seats are arranged at the inner end of the sliding frame adjacent to the bearing beam. A moving mechanism for moving the section steel on the bearing beam to the bearing seat is arranged in the frame. A driving mechanism for driving the sliding frame to slide is arranged in the frame. An installation frame is arranged on one side of the frame adjacent to the laser section steel cutting machine. A lifting frame is slidably arranged vertically on the installation frame. A driving cylinder is arranged vertically in the installation frame. The end of the piston rod of the driving cylinder faces upward and is connected to the lifting frame. Along the length direction of the frame, two horizontally arranged first slide rails are arranged at intervals on the top of the lifting frame. The two first slide rails are slidably arranged with a workbench through first sliders. On one side of the workbench along the length direction of the frame, two clamping cylinders are arranged at intervals. A baffle is arranged on the side of the workbench opposite to the clamping cylinders. The piston rod of the clamping cylinder faces the baffle and is provided with a push plate.

[0006] By adopting the above technical solution, a frame, a sliding frame, a bearing seat, a moving mechanism, a driving mechanism, a mounting frame, a lifting frame, a workbench, a clamping cylinder and a baffle are provided. A number of steel profiles are arranged on a bearing beam. The steel profiles on the bearing beam are moved towards the bearing seat by the moving mechanism. After a steel profile is moved onto the bearing seat, the driving mechanism is used to drive the sliding frame to move until the steel profile on the bearing seat is aligned with the remaining material on the chuck of the laser steel profile cutting machine. The workbench is slid so that the steel profile is located in the area between the clamping cylinder and the baffle. Then the driving cylinder is used to drive the lifting frame to rise until the workbench surface contacts the steel profile. Then the clamping cylinder is used to push the push plate to clamp the steel profile and the remaining material of the steel profile on the laser steel profile cutting machine between the push plate and the baffle. Subsequently, the remaining material of the steel profile is welded to the steel profile, avoiding waste of the remaining material of the steel profile. Moreover, after the steel profile moves on the bearing beam and the sliding frame and is welded to the remaining material, it avoids the collision of the machine caused by manual feeding, thus avoiding potential safety hazards.

[0007] Further, a number of second slide rails are arranged at intervals along the length direction of the frame at the bottom of the sliding frame, and a number of second sliders are arranged at intervals along the length direction of the frame on the frame. The second slide rails are slidably arranged on the corresponding second sliders.

[0008] By adopting the above technical solution, the second slide rails and the second sliders are provided to ensure the stability of the sliding of the sliding frame.

[0009] Further, there are two groups of the moving mechanisms, which are respectively arranged on one side of the frame close to the laser steel profile cutting machine and on one side of the frame far from the laser steel profile cutting machine.

[0010] By adopting the above technical solution, two groups of the moving mechanisms are provided to ensure the stable movement of the steel profiles.

[0011] Further, the moving mechanism includes a number of moving plates and a rotating motor arranged on the frame. Two rotating shafts arranged at intervals in the width direction of the frame are rotatably arranged on the frame. Driven wheels are arranged on the rotating shafts. A driving wheel is arranged on the output shaft of the rotating motor. The driving wheel is connected with the two driven wheels by a chain. Eccentric wheels are arranged at both ends of the rotating shafts. Circular holes are formed in the moving plates. The eccentric wheels are rotatably arranged in the circular holes. A horizontally arranged moving beam is jointly arranged on the two moving plates on the same side of the two rotating shafts.

[0012] By adopting the above technical solution, the moving plates, the rotating motor, the rotating shafts, the driven wheels, the driving wheel, the eccentric wheels and the moving beam are provided. The driving wheel is driven to rotate by the rotating motor. Under the action of the chain, the two driven wheels are driven to rotate, thereby driving the rotating shafts and the eccentric wheels to rotate. When the eccentric wheels rotate, the moving plates are driven to move, so that both ends of the moving beam move synchronously, so that the moving beam always remains horizontal during the movement.

[0013] Further, the driving mechanism includes a driving motor horizontally arranged on the frame. A rack with a length direction consistent with the width direction of the frame is arranged on the sliding frame. The length direction of the output shaft of the driving motor is consistent with the length direction of the frame and a gear is arranged at the end. The gear meshes with the rack.

[0014] By adopting the above technical solution, the driving motor, the rack and the gear are provided. The driving motor drives the gear to rotate, so that the rack drives the sliding frame to move.

[0015] Further, a plurality of third sliders are arranged in the mounting frame. A plurality of third sliding rails are vertically arranged on the lifting frame. The third sliding rails are slidably arranged in the corresponding third sliders.

[0016] By adopting the above technical solution, the third sliders and the third sliding rails are provided to ensure the stability of the sliding of the lifting frame.

[0017] Further, a square notch is formed on the workbench between the two clamping cylinders. The baffle is provided with a square notch corresponding to the square notch.

[0018] By adopting the above technical solution, the square notch and the square notch are provided, so that the joint of the profiled bar waste and the profiled bar is located at the square notch and the square notch, which is convenient for the staff to weld the profiled bar waste and the profiled bar.

[0019] In summary, the utility model has the following beneficial effects: In this application, the frame, the sliding frame, the bearing seat, the moving mechanism, the driving mechanism, the mounting frame, the lifting frame, the workbench, the clamping cylinder and the baffle are provided. A plurality of profiled bars are arranged on the bearing beam. The profiled bars on the bearing beam are moved towards the bearing seat by the moving mechanism. When a profiled bar is moved to the bearing seat, the driving mechanism is used to drive the sliding frame to move until the profiled bar on the bearing seat is aligned with the waste on the chuck of the laser profiled bar cutting machine. The workbench is slid so that the profiled bar is located in the area between the clamping cylinder and the baffle. Then the driving cylinder is used to drive the lifting frame to rise until the workbench surface contacts the profiled bar. Then the clamping cylinder is used to push the push plate to clamp the profiled bar and the profiled bar waste on the laser profiled bar cutting machine between the push plate and the baffle. Subsequently, the profiled bar waste and the profiled bar are welded, avoiding the waste of profiled bar waste. Moreover, the profiled bar is welded with the waste after moving on the bearing beam and the sliding frame, avoiding the collision of the machine caused by manual feeding, thus avoiding potential safety hazards.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] As Figures 1-7As shown in the figure, an automatic feeding device for a laser section steel cutting machine according to an embodiment of the present application includes a frame 10, a sliding frame 20, a moving mechanism 30, a driving mechanism 40, a mounting frame 50, a lifting frame 51, and a workbench 60. The frame 10 is arranged along the feeding direction of the laser section steel cutting machine. A plurality of load-bearing beams 11 are arranged at intervals along the length direction of the top of the frame 10. The length direction of the load-bearing beam 11 is perpendicular to the length direction of the frame 10 and is used for placing section steel. The sliding frame 20 is slidably arranged on the frame 10 along the width direction of the frame 10. A plurality of load-bearing seats 21 are arranged at the inner end of the sliding frame 20 adjacent to the load-bearing beam 11, so that the sliding frame 20 and the load-bearing seats 21 slide synchronously. The moving mechanism 30 is arranged in the frame 10 and is used to move the section steel on the load-bearing beam 11 to the load-bearing seats 21. The driving mechanism 40 is arranged in the frame 10 and is used to drive the sliding frame 20 to slide. The mounting frame 50 is arranged on one side of the frame 10 adjacent to the laser section steel cutting machine. The lifting frame 51 is vertically slidably arranged on the mounting frame 50. Two horizontally arranged first slide rails 53 are arranged at intervals along the length direction of the top of the lifting frame 51. The length direction of the first slide rails 53 is perpendicular to the length direction of the frame 10. A workbench 60 is slidably arranged on the two first slide rails 53 through a first slider, so that the workbench 60 can slide along the width direction of the frame 10 on the first slide rails 53. Two clamping cylinders 61 are arranged at intervals along the length direction of the workbench 60 on one side. A baffle 62 is arranged on the workbench 60 on the side opposite to the clamping cylinders 61. The piston rod of the clamping cylinder 61 faces the baffle 62 and is provided with a push plate 63. The clamping cylinder 61 pushes the push plate 63 to clamp the section steel and the section steel waste on the laser section steel cutting machine between the push plate and the baffle 62. Then, the section steel waste is welded to the section steel, avoiding the situation that the section steel waste cannot reach the required length and cannot be used, thereby avoiding the waste of section steel waste.

[0030] Specifically, the moving mechanism 30 includes a moving plate 31 and a rotating motor 32. The rotating motor 32 is arranged on the frame 10. Two rotating shafts 33 are rotatably arranged on the frame 10 at intervals in the width direction of the frame 10. The length direction of the rotating shafts 33 is the same as the length direction of the frame 10. Driven wheels 34 are arranged on the rotating shafts 33. A driving wheel 35 is arranged on the output shaft of the rotating motor 32. The driving wheel 35 is connected to the two driven wheels 34 by a chain 36. When the rotating motor 32 drives the driving wheel 35 to rotate, the two driven wheels 34 are driven to rotate under the action of the chain 36, thereby driving the rotating shafts 33 to rotate. Eccentric wheels 37 are arranged at both ends of the rotating shafts 33. There are four moving plates 31, and circular holes are formed in the moving plates 31. The four eccentric wheels 37 are respectively rotatably arranged in the four circular holes. A horizontally arranged moving beam 38 is commonly arranged on the two moving plates 31 on the same side of the two rotating shafts 33. When the rotating shafts 33 rotate, the eccentric wheels 37 are driven to rotate, thereby driving the moving plates 31 to move, so that both ends of the moving beam 38 move synchronously, so that the moving beam 38 always maintains a horizontal state during the movement. When the moving beam 38 moves to the lowest position, the height of its top surface is lower than the height of the top surface of the bearing beam 11. When the moving beam 38 moves to the highest position, the height of its top surface is higher than the height of the top surface of the bearing beam 11. There are two groups of moving mechanisms 30, which are respectively arranged on the side of the frame 10 close to the laser section steel cutting machine and on the side of the frame 10 far from the laser section steel cutting machine to ensure the stable movement of the section steel.

[0031] When setting, a plurality of second slide rails 22 are arranged at intervals along the length direction of the frame 10 at the bottom of the sliding frame 20. A plurality of second sliders 23 are arranged at intervals along the length direction of the frame 10 on the frame 10. The second slide rails 22 are slidably arranged on the corresponding second sliders 23 to ensure the stability of the sliding of the sliding frame 20. The driving mechanism 40 includes a driving motor 41 horizontally arranged on the frame 10. A rack 42 with a length direction the same as the width direction of the frame 10 is arranged on the sliding frame 20. The length direction of the output shaft of the driving motor 41 is the same as the length direction of the frame 10 and a gear 43 is arranged at the end. The gear 43 meshes with the rack 42. The driving motor 41 drives the gear 43 to rotate, so that the rack 42 drives the sliding frame 20 to move.

[0032] During specific installation, several third sliders 54 are arranged inside the mounting frame 50, and several third slide rails 55 are vertically arranged on the lifting frame 51. The third slide rails 55 are slidably arranged inside the corresponding third sliders 54 to ensure the stability of the lifting of the lifting frame 51. A driving cylinder 52 is vertically arranged inside the mounting frame 50. The end of the piston rod of the driving cylinder 52 faces upward and is connected to the lifting frame 51. The lifting frame 51 is driven to lift by the driving cylinder 52. A square notch 64 is formed on the workbench 60 between the two clamping cylinders 61. The baffle 62 is provided with a square notch 65 corresponding to the square notch 64. When the laser section steel cutting machine processes and cuts the section steel, when the end of the section steel residue reaches the square notch 64, the laser section steel cutting machine is stopped. The section steel on the bearing beam 11 is moved towards the bearing seat 21 through the moving mechanism 30. After a section steel is moved onto the bearing seat 21, the sliding frame 20 is driven to move by the driving mechanism 40 until the section steel on the bearing seat 21 is aligned with the residue on the chuck of the laser section steel cutting machine. A pushing cylinder can be arranged on the side of the machine frame 10 away from the laser section steel cutting machine. The section steel is pushed towards the section steel residue by the pushing cylinder to further ensure that the end of the section steel contacts the end of the section steel residue, so that the joint of the section steel residue and the section steel is located at the square notch 64 and the square notch 65, which is convenient for the staff to weld the section steel residue and the section steel.

[0033] In this embodiment, the working principle of the automatic loading device of the laser section steel cutting machine is as follows: A number of section steels are arranged on the bearing beam 11. The rotation motor 32 is started to drive the driving wheel 35 to rotate, driving the driven wheel 34, the rotating shaft 33, and the eccentric wheel 37 to rotate, thereby driving the moving plate 31 and the moving beam 38 to move, and moving the section steel on the bearing beam 11 towards the bearing seat 21. After a section steel is moved onto the bearing seat 21, the driving motor 41 is started to drive the gear 43 to rotate, so that the rack 42 drives the sliding frame 20 to move until the section steel on the bearing seat 21 is aligned with the residue on the chuck of the laser section steel cutting machine. The workbench 60 is slid to make the section steel located in the area between the clamping cylinder 61 and the baffle 62. Then, the lifting frame 51 is driven to rise by the driving cylinder 52 until the tabletop of the workbench 60 contacts the section steel. Then, the clamping cylinder 61 is used to push the push plate 63 to clamp the section steel and the section steel residue on the laser section steel cutting machine between the push plate and the baffle 62. Subsequently, the section steel residue and the section steel are welded, avoiding the waste of the section steel residue. Moreover, the section steel moves on the bearing beam 11 and the sliding frame 20 and then is welded to the residue, avoiding the collision of the machine caused by manual loading, thus avoiding potential safety hazards.

[0034] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
