Description

Technical Field

[0001] The utility model relates to the technical field of straightening machines, in particular to a safety protection mechanism for a straightening machine. Background Technique

[0002] When steel bars leave the factory, their length is generally one hundred to several hundred meters. For convenient transportation, they will be wound into a coil (roll) for transportation. Before use, they will be straightened and cut into appropriate lengths (about dozens of meters). A steel bar straightening machine is used to straighten the coiled steel bars.

[0003] At present, when straightening and processing steel bars on construction sites, most straightening machines do not have an installation protection function. According to a steel bar straightening machine with a protection mechanism disclosed in the patent application number 202022777845.5, the beneficial effect of its technical solution is to set a protection mechanism at the feeding end of the steel bar straightening machine. On the one hand, the bent steel bar can be restricted within the protection mechanism to prevent the bent steel bar from causing potential safety hazards to nearby workers when advancing. On the other hand, when the protection mechanism restricts the advancement of the steel bar, it can also perform preliminary straightening on it to prevent the part with a large bending arc of the steel bar from easily causing excessive wear or damage to the feeding port of the steel bar straightening machine. This steel bar straightening machine with a protection mechanism can not only prevent injuries to personnel during steel bar straightening but also prevent bent steel bars from damaging the equipment, greatly improving safety and production efficiency.

[0004] The above patent has defects. Since the coiled steel bar is relatively hard, it is necessary for the operator to manually pass one end of the steel bar through the protection mechanism. Moreover, while the protection mechanism protects the steel bar through the arc-shaped rod, it also has a side effect of limiting its position, making it very difficult for one end of the bent steel bar to be easily removed from the protection mechanism, which requires a large amount of labor and results in poor use effects. Therefore, we provide a safety protection mechanism for a straightening machine to solve this problem. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and a safety protection mechanism for a straightening machine is proposed to solve this problem.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solution:

[0007] Design a safety protection mechanism for a straightening machine, including a straightening machine body. A console is welded to the left side of the straightening machine body. An activity groove is arranged at the upper end of the console. A chassis is installed at the upper end of the console. A sleeve column is integrally connected to the upper end of the chassis. A protection component and a blocking component are arranged at the upper end of the console. The lower ends of the protection component and the blocking component penetrate through the console and extend to the lower part thereof to be connected to each other;

[0008] The protection component includes a servo motor installed at the lower end of the operating table. The output end of the servo motor is connected to a rotating shaft. A gear is installed on the outer side of the rotating shaft. Two tooth plates are symmetrically engaged with the outer side of the gear. The upper ends of the tooth plates are both connected to a buffer component through connecting rods passing through the movable slots.

[0009] Furthermore, the buffer component includes a C-shaped steel plate installed at the upper end of the connecting rod. A support plate is welded inside the C-shaped steel plate. Springs are equidistantly connected to one side of the support plate. One end of each spring is connected to a rubber seat. The rubber seats are connected to a stop block through movable columns passing through the support plate on one side. A rubber block is bonded to one side of the stop block.

[0010] Furthermore, convex slide bars are symmetrically connected to one end of each tooth plate. A limiting component is installed at the lower end of the operating table and is slidably connected thereto. The limiting component includes four slide rails slidably connected to the convex slide bars. A fixing rod is commonly connected between every two slide rails. Mounting frames are symmetrically connected to the upper ends of two of the slide rails. The mounting frames are screwed to the operating table.

[0011] Furthermore, the shielding component includes a first bevel gear installed on the outer side of the rotating shaft. A second bevel gear is engaged with the outer side of the first bevel gear. A lead screw is installed inside the second bevel gear. A bearing seat is installed at the lower end of the operating table and is rotatably connected thereto. The upper end of the lead screw passes through the operating table and is screwed to a support block. A hollow disk is integrally connected to one side of the support block. A rubber pad is bonded to the lower end of the hollow disk. The hollow disk is located above the sleeve column.

[0012] Furthermore, a positioning rod is connected to the upper end of the operating table. The upper end of the positioning rod passes through the support block and is connected to a limiting block.

[0013] Furthermore, a protective cover is screwed to the upper end of the straightening machine body. Protective fences are symmetrically installed at the upper end of the operating table.

[0014] A safety protection mechanism for a straightening machine proposed by the present utility model has the beneficial effects that:

[0015] 1. An operator can easily manually pull one end of a steel bar into the straightening machine body for straightening work. Subsequently, the buffer component of the protection component provides anti-breakage and swing protection for both sides of the steel bar, effectively avoiding the steel bar from breaking and flying out and causing harm to the operator, and improving the protection effect;

[0016] 2. While the rotating shaft of the protection component rotates, the first bevel gear on its outer side drives the second bevel gear and the lead screw in its inner cavity to rotate. Further, the lead screw drives the support block screwed on its outer side to move downward. Under the insertion and limitation of the positioning rod, the support block synchronously drives the hollow disc to move downward, facilitating the vertical shielding and protection of the coiled steel bar outside the socket sleeve column. It is convenient to pull the steel bar easily while providing multi-directional anti-fracture swing protection for the steel bar, effectively improving the safety protection effect;

[0017] 3. When the steel bar breaks accidentally, the protection component and the shielding component are operated and reset in the direction, which facilitates the buffer component of the protection component and the hollow disc of the shielding component to move away from the steel bar. It is convenient for the operator to manually take out the steel bar and straighten it again, effectively improving the use effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Refer toFigures 1-5 , a straightening machine safety protection mechanism, including a straightening machine body 1. A control console 3 is welded to the left side of the straightening machine body 1. An activity groove 4 is arranged at the upper end of the control console 3. A chassis 5 is installed at the upper end of the control console 3. A sleeve column 6 is integrally connected to the upper end of the chassis 5. A protection component 7 and a blocking component 8 are arranged at the upper end of the control console 3.

[0026] The lower ends of the protection component 7 and the blocking component 8 penetrate through the control console 3 and extend to the lower part thereof to be connected to each other. The protection component 7 includes a servo motor 71 installed at the lower end of the control console 3. The output end of the servo motor 71 is connected to a rotating shaft 72. A gear 73 is installed on the outer side of the rotating shaft 72. Two tooth plates 74 are symmetrically meshed with the outer side of the gear 73. The upper ends of the tooth plates 74 both pass through the activity groove 4 through connecting rods 75 and are connected to a buffer component 76. The buffer component 76 includes a C-shaped steel plate 761 installed at the upper end of the connecting rod 75. A support plate 762 is welded to the inner side of the C-shaped steel plate 761. A plurality of springs 763 are equidistantly connected to one side of the support plate 762. One end of each spring 763 is connected to a rubber seat 764. One side of each rubber seat 764 passes through the support plate 762 through a movable column 765 and is connected to a blocking block 766. A rubber block 767 is adhered to one side of the blocking block 766. One end of each tooth plate 74 is symmetrically connected with a convex slide bar 77. A limiting component 78 is installed at the lower end of the control console 3 and is slidably connected thereto. The limiting component 78 includes four slide rails 781 slidably connected with the convex slide bars 77. A fixing rod 783 is commonly connected between every two slide rails 781. Mounting frames 782 are symmetrically connected to the upper ends of two of the slide rails 781. The mounting frames 782 are screwed to the control console 3.

[0027] The output end of the servo motor 71 drives the rotating shaft 72 to rotate. The rotating shaft 72 drives the gear 73 on its outer side to rotate. The gear 73 simultaneously drives the two tooth plates 74 to move in the same direction. Further, the tooth plates 74 drive the buffer component 76 to move through the connecting rods 75 after passing through the activity groove 4. When a plurality of rubber blocks 767 of the buffer component 76 move near the steel bar, it is convenient to play a protective role, avoiding that after the steel bar accidentally breaks, its released elasticity swings randomly and causes harm to the operator. And when the steel bar swings, it impacts the rubber block 767. Then the rubber block 767 buffers its elastic potential energy. And when the elastic force is too large, the rubber block 767 compresses the spring 763 and simultaneously drives the movable column 765 to move. The blocking block 766 on one side of the movable column 765 drives the rubber block 767 to impact the C-shaped steel plate 761. The rubber block 767 plays an effective buffering protection, and finally releases the elastic potential energy after the steel bar breaks, which is convenient to effectively avoid the harm caused by the steel bar breaking and throwing out to the operator, and improves the protection effect.

[0028] The shielding component 8 includes a first bevel gear 81 installed outside the rotating shaft 72. A second bevel gear 82 is meshed outside the first bevel gear 81. A lead screw 83 is installed inside the cavity of the second bevel gear 82. A bearing block 84 is installed at the lower end of the operating table 3 and is rotatably connected thereto. The upper end of the lead screw 83 penetrates through the operating table 3 and is screwed with a support block 85. One side of the support block 85 is integrally connected with a hollow disk 86. A rubber pad 87 is bonded to the lower end of the hollow disk 86. The hollow disk 86 is located above the sleeve column 6. A positioning rod 88 is connected to the upper end of the operating table 3. The upper end of the positioning rod 88 penetrates through the support block 85 and is connected with a limiting block 89.

[0029] While the rotating shaft 72 is rotating, the first bevel gear 81 outside the rotating shaft 72 drives the second bevel gear 82 and the lead screw 83 inside its cavity to rotate. Then, the lead screw 83 drives the support block 85 screwed outside it to move downward. Under the insertion and limitation of the positioning rod 88, the support block 85 synchronously drives the hollow disk 86 to move downward, which is convenient for vertically shielding and protecting the coiled steel bars outside the sleeve column 6. Moreover, the rubber pad 87 at the lower end of the hollow disk 86 effectively plays a buffering and protecting role, preventing the steel bars on the surface of the coiled steel bars from bouncing upward and directly hitting the hollow disk 86, resulting in damage.

[0030] A protective cover 2 is screwed to the upper end of the straightening machine body 1. Protective fences 9 are symmetrically installed at the upper end of the operating table 3. The protective cover 2 covers the straightening machine body 1 to prevent larger external objects from entering it and causing damage to the internal components during movement. And by designing the protective fences 9 to block the elastic potential energy released when the coiled steel bars are used up, it effectively plays a protective role.

[0031] Working principle: The utility model controls and connects the servo motor 71 through an external control switch. When in use, the coiled steel bars are sleeved outside the sleeve column 6 and located on the chassis 5. One end of the coiled steel bars is pulled into the straightening machine body 1, and the straightening work is carried out by starting the straightening machine body 1. Then, while the straightening machine body 1 drives the steel bars to be straightened, it also drives them to move. At the same time, by turning on the switch of the servo motor 71, the output end of the servo motor 71 drives the rotating shaft 72 to rotate, and the rotating shaft 72 drives the gear 73 outside it to rotate. The gear 73 simultaneously drives the two toothed plates 74 to move in the same direction. Then, the toothed plates 74 drive the buffer assembly 76 to move through the connecting rod 75 after passing through the movable slot 4. When the multiple rubber blocks 767 of the buffer assembly 76 move near the steel bars, it is convenient to play a protective role, avoiding the elastic random swing of the steel bars after accidental fracture and causing harm to the operators. And when the steel bars swing, they hit the rubber blocks 767, and then the rubber blocks 767 buffer their elastic potential energy. And when the elastic force is too large, the rubber blocks 767 compress the spring 763 and simultaneously drive the movable column 765 to move. The stopper 766 on one side of the movable column 765 drives the rubber block 767 to hit the C-shaped steel plate 761. The rubber block 767 plays an effective buffering protection, and finally releases the elastic potential energy after the steel bar breaks, effectively avoiding the harm caused by the steel bar breaking and throwing out to the operators, improving the protection effect. At the same time, the first bevel gear 81 outside the rotating shaft 72 drives the second bevel gear 82 and the lead screw 83 inside its cavity to rotate. Then, the lead screw 83 drives the support block 85 screwed outside it to move downward. Under the plug-in limit of the positioning rod 88, the support block 85 synchronously drives the hollow disc 86 to move downward, facilitating the vertical shielding protection of the coiled steel bars sleeved outside the sleeve column 6. And the rubber pad 87 at the lower end of the hollow disc 86 effectively plays a buffering and protective effect, preventing the steel bars on the surface of the coiled steel bars from bouncing upward and directly hitting the hollow disc 86 and causing damage. And by designing the protective fence 9 to block the elastic potential energy released after the coiled steel bars are used up and swing, it effectively plays a protective effect.

[0032] The above is only the preferred specific implementation mode of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent replacement or change, and should be covered within the protection scope of the utility model.
