[0002] When processing steel bars, generally multiple processes are required, including the steel bar extrusion molding process. Currently, when extruding and molding steel bars, they are generally extruded and molded one by one, with relatively low efficiency. When synchronously extruding and molding multiple steel bars, the steel bars need to be processed first. By cutting, the lengths of multiple steel bars are made the same. Currently, generally, when placing, the ends of the steel bars are aligned manually and then cut, or the uneven parts of the steel bars are cut by a machine, cutting both ends of the steel bars and only leaving the middle parts with the same length, and then extruding and molding the steel bars, resulting in relatively low efficiency of steel bar extrusion and molding.

[0024] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0025] Embodiment 1

[0026] As Figures 1 to 6 shown, a steel bar extrusion forming device includes an equipment frame 1. A horizontally arranged conveyor belt 2 is installed inside the equipment frame 1. A plurality of groups of feeding troughs 3 are formed on the surface of the conveyor belt 2. The feeding troughs 3 are arranged along the moving direction of the conveyor belt 2. A slitting knife 4 is arranged above the equipment frame 1. A lifting structure is arranged above the slitting knife 4. The lifting structure drives the slitting knife 4 to move vertically. Two horizontally distributed extrusion rollers 5 are arranged below the inside of the equipment frame 1. A driving member is arranged on one side of the two extrusion rollers 5. The driving member drives the two extrusion rollers 5 to rotate relatively. The slitting knife 4 is located between the extrusion rollers 5 and the conveyor belt 2;

[0027] A limiting member 6 is provided below the cutting knife 4. The limiting member 6 moves horizontally along the equipment frame 1. An adjusting structure is provided outside the limiting member 6. The adjusting structure is used to drive the limiting member 6 to rotate downward. A plurality of horizontally arranged fixing members 8 are provided between the limiting member 6 and the conveyor belt 2. The fixing members 8 are connected to the limiting member 6 through a connecting structure. A cylinder 9 is inserted inside one side of the fixing member 8 close to the conveyor belt 2. A fixing groove 10 is formed inside the cylinder 9. The opening of the fixing groove 10 faces the conveyor belt 2 direction. The fixing groove 10 is funnel-shaped. The opening diameter of the fixing groove 10 is larger than the internal diameter. Two horizontally arranged clamping blocks 11 are provided inside the fixing groove 10. A triggering structure is provided between the two clamping blocks 11. The triggering structure drives the two clamping blocks 11 to move closer to or away from each other.

[0028] Place the steel bars to be processed inside the conveying groove 3 of the conveyor belt 2. The conveyor belt 2 drives the steel bars to move horizontally inside the equipment frame 1. One end of the steel bar is inserted inside the fixing groove 10. With the cooperation of the triggering structure, the triggering structure drives the two clamping blocks 11 to move closer to each other to clamp one end of the steel bar, thereby restricting one end of the steel bar inside the cylinder 9. When all the steel bars are inserted inside the cylinder 9, the steel bars push the fixing members 8 and the limiting member 6 to move synchronously. After the limiting member 6 moves to the farthest distance, the steel bars stop moving. With the cooperation of the lifting structure, the lifting structure drives the cutting knife 4 to move downward. The cutting knife 4 cuts the steel bars. The adjusting structure drives the limiting member 6 to rotate downward, thereby driving the cut steel bars to rotate downward. After the steel bars contact the pressing rollers 5, the steel bars fall off from inside the fixing groove 10. The driving member drives the two pressing rollers 5 to rotate relative to each other, so that the pressing rollers 5 can perform extrusion forming on the steel bars. By providing the fixing groove 10 and the clamping blocks 11, one end of the steel bar can be clamped, increasing the stability of the steel bars during movement. With the cooperation of the fixing members 8 and the limiting member 6, multiple steel bars can be aligned. There is no need to manually align the steel bars when placing them, which is beneficial to improving the efficiency of steel bar extrusion forming. At the same time, there is no need to align the steel bars by cutting, which is beneficial to reducing waste of resources and lowering the cost of steel bar extrusion forming. By providing the adjusting structure, the cut steel bars are rotated downward, facilitating direct extrusion forming of the cut steel bars. There is no need to transfer the cut steel bars to another device for extrusion forming, which is beneficial to streamlining the process of steel bar extrusion forming and further improving the efficiency of steel bar extrusion forming.

[0029] The connecting structure includes a push plate 16, a sleeve 17, a push rod 18, a second spring 19 and a rotating assembly. The push plate 16 is connected to the limiting member 6 through the sleeve 17. The push plate 16 is vertically arranged, and the sleeve 17 is horizontally arranged. The sleeve 17 is slidably sleeved outside the limiting member 6. The push rod 18 and the second spring 19 are inserted inside the sleeve 17, and the push rod 18 is located between the second spring 19 and the fixing member 8. The sleeve 17 is connected to the limiting member 6 through the rotating assembly, and the rotating assembly is used to adjust the movement of the sleeve 17 inside the limiting member 6.

[0030] The rotating assembly includes a convex block 20, a through groove 21, a sliding groove 22 and a sliding block 23. The convex block 20 is rotatably inserted inside the sleeve 17, and the convex block 20 is slidably connected to the push rod 18. One end of the convex block 20 penetrates through the sleeve 17 and extends to the outside of the sleeve 17. The through groove 21 is opened inside the limiting member 6, and the through groove 21 is slidably matched with the convex block 20. The outer surface of the push rod 18 is provided with a sliding groove 22, and the sliding groove 22 is arranged obliquely along the surface of the push rod 18. The sliding block 23 is fixedly installed inside the sleeve 17, and the sliding block 23 is slidably connected to the sliding groove 22.

[0031] After the steel bar is inserted into the fixing groove 10, the steel bar can push the fixing member 8 and the push rod 18 to move inside the sleeve 17. At this time, the second spring 19 is compressed and deformed. Under the action of the sliding block 23, the position of the sliding block 23 remains unchanged. The sliding groove 22 is arranged obliquely along the surface of the push rod 18. When the push rod 18 moves, the sliding block 23 slides inside the sliding groove 22, so as to drive the push rod 18 to rotate. When the push rod 18 rotates, it drives the convex block 20 to rotate synchronously. When the convex block 20 rotates to the position of the through groove 21, the convex block 20 no longer restricts the movement of the sleeve 17, and the sleeve 17 drives the convex block 20 to move synchronously, so that the convex block 20 can pass through the through groove 21.

[0032] The triggering structure includes a pushing frame 12, a connecting rod 39 and a limiting structure. The pushing frame 12 is slidably inserted inside the fixing groove 10, and the pushing frame 12 moves horizontally along the fixing groove 10. The connecting rod 39 is rotatably installed between the pushing frame 12 and the clamping block 11. The fixing member 8 is connected to the sleeve 17 through the limiting structure, and the limiting structure is used to adjust the sliding of the fixing member 8 inside the sleeve 17.

[0033] The limiting structure includes a movable groove 13, a first spring 14 and a wedge block 15. The movable groove 13 is opened inside the sleeve 17, and the movable groove 13 is vertically arranged. The first spring 14 and the wedge block 15 are inserted inside the movable groove 13 in sequence from inside to outside. The pushing frame 12 is in an I shape, and the pushing frame 12 is in contact and cooperation with the wedge block 15.

[0034] After the steel bar is inserted into the fixing groove 10, one end of the steel bar contacts the pushing frame 12 and drives the pushing frame 12 to move. When the pushing frame 12 moves into the fixing groove 10, with the cooperation of the connecting rod 39, the pushing frame 12 can pull the two clamping blocks 11 closer to each other through the connecting rod 39, so as to clamp one end of the steel bar and fix one end of the steel bar inside the column 9. Since the pushing frame 12 is in an I shape, while the pushing frame 12 pulls the connecting rod 39, the pushing frame 12 can push the wedge block 15 into the moving groove 13. At this time, the first spring 14 is compressed and deformed. When the wedge block 15 is completely pushed into the moving groove 13, the steel bar can push the fixing part 8 to slide into the sleeve 17.

[0035] A cavity 7 is formed inside the limiting part 6, and a positioning component is arranged inside the cavity 7. The limiting part 6 is connected to the equipment frame 1 through the positioning component, and the positioning component is used to adjust the sliding of the limiting part 6 inside the equipment frame 1.

[0036] The positioning component includes a trigger plate 24, a third spring 25, a positioning block 26 and a fourth spring 27. The positioning block 26 is horizontally arranged between the limiting part 6 and the inner wall of the equipment frame 1. The positioning block 26 penetrates through the limiting part 6 and extends into the limiting part 6. A positioning groove corresponding to the positioning block 26 is formed on the inner wall of the equipment frame 1. The trigger plate 24 is slidably inserted into the cavity 7. The trigger plate 24 is connected to the sleeve 17. A third spring 25 is arranged between the trigger plate 24 and the inner wall of the limiting part 6. The third spring 25 is horizontally arranged. The trigger plate 24 is in contact and cooperation with the positioning block 26. The outer surface of the positioning block 26 is sleeved with a fourth spring 27. The fourth spring 27 is located between the inner wall of the limiting part 6 and the positioning block 26.

[0037] When the push plate 16 moves towards the limiting part 6, the push plate 16 drives the trigger plate 24 to move synchronously. At this time, the third spring 25 is compressed and deformed. In the initial state, the trigger plate 24 abuts against the positioning block 26. At this time, the fourth spring 27 is compressed and deformed. After the push plate 16 drives the trigger plate 24 to move synchronously, the trigger plate 24 is separated from the positioning block 26. Under the elastic force of the fourth spring 27, the fourth spring 27 drives the positioning block 26 to move into the limiting part 6, so that the limiting part 6 can be separated from the equipment frame 1. While the steel bar moves the push plate 16, it can also drive the limiting part 6 to move synchronously.

[0038] A connecting block 28 is arranged between the limiting part 6 and the inner wall of the equipment frame 1. The connecting block 28 is slidably connected to the equipment frame 1. A first threaded rod 29 is threadedly connected to the inside of the connecting block 28. The first threaded rod 29 is horizontally arranged. One end of the first threaded rod 29 is provided with a rotating part, and the rotating part drives the first threaded rod 29 to rotate.

[0039] When the limiting member 6 moves to the maximum distance and completes the extrusion forming of the steel bar, connect the rotating member to an external power source. The rotating member can drive the first threaded rod 29 to rotate. The first threaded rod 29 is threadedly connected to the connecting block 28. When the first threaded rod 29 rotates, it can drive the connecting block 28 to move horizontally, so as to drive the limiting member 6 to move towards the conveyor belt 2 and reset the limiting member 6.

[0040] The lifting structure includes a motor 38, a pressing plate 30 and a second threaded rod 31. The motor 38 is installed above the equipment frame 1. The pressing plate 30 is installed between the output end of the motor 38 and the cutting knife 4. The pressing plate 30 is horizontally arranged. The second threaded rod 31 is installed below the output shaft of the motor 38. The second threaded rod 31 is vertically arranged. The second threaded rod 31 is threadedly connected to the pressing plate 30.

[0041] A cutting platform 32 is arranged below the cutting knife 4. The cutting platform 32 is horizontally arranged. The cutting platform 32 is slidably connected to the equipment frame 1. The cutting platform 32 is threadedly connected to the second threaded rod 31. The threads at both ends of the second threaded rod 31 are arranged in opposite directions. The second threaded rod 31 drives the cutting platform 32 and the cutting knife 4 to approach or move away from each other.

[0042] Connect the motor 38 to an external power source. The motor 38 drives the second threaded rod 31 to rotate. The second threaded rod 31 drives the cutting platform 32 and the pressing plate 30 to approach each other, so as to drive the cutting platform 32 and the cutting knife 4 to approach each other. The cutting platform 32 plays a supporting role for the steel bar, and the cutting knife 4 can cut the steel bar. With the cooperation of the cutting platform 32 and the cutting knife 4, it is convenient to cut the steel bar, making the cutting effect of the steel bar better and reducing the probability of the steel bar deforming during cutting.

[0043] The adjusting structure includes a shaft member 33, a semi-gear 34, a rack 35, a track 36 and a connecting plate 37. The shaft member 33 is fixedly installed on the side of the limiting member 6 and is horizontally arranged. The shaft member 33 passes through the connecting block 28 and is slidably connected to the connecting block 28. The semi-gear 34 is installed at one end of the shaft member 33 away from the limiting member 6. The track 36 is installed on the outer wall of the equipment frame 1. The rack 35 is slidably installed inside the track 36 and meshes with the semi-gear 34. The connecting plate 37 is rotatably installed between the rack 35 and the pressing plate 30.

[0044] When the limiting member 6 moves to the maximum distance, the pressing plate 30 pushes the rack 35 to slide on the track 36 through the connecting plate 37. The rack 35 slides in the direction away from the pressing plate 30. At this time, the rack 35 is not engaged with the half gear 34. When the pressing plate 30 moves upward, the pressing plate 30 drives the rack 35 to slide in the direction close to the pressing plate 30. At this time, the rack 35 is engaged with the half gear 34, and the rack 35 can drive the half gear 34 to rotate. With the cooperation of the shaft member 33, the rack 35 can drive the limiting member 6 to rotate downward, so that the cut steel bar changes from a horizontal state to a vertical state, which is convenient for the pressing roller 5 to press and form the steel bar.

[0045] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
