Description

Technical Field

[0001] This utility model relates to shearing lines, and more particularly to a systematic combined shearing line, belonging to the field of shearing line technology. Background Technology

[0002] A systematic modular rebar shearing line is a highly efficient and precise rebar processing equipment, typically composed of multiple parts to achieve automated and large-scale rebar shearing operations.

[0003] CN207642205U discloses a CNC rebar shearing line. An automatic rebar hopper is installed on one side of a discharge tipping machine and includes multiple parallel and equidistantly arranged finished product racks. Each rack includes a first column, a second column, a third column, a fourth column, a fifth column, a receiving plate, a first tilting plate, a second tilting plate, a third tilting plate, a first tilting cylinder, a second tilting cylinder, and a third tilting cylinder. The first, second, third, fourth, and fifth columns are parallel and equidistantly spaced on a connecting plate from front to back, with their heights decreasing sequentially. The rebar rolls down the shearing line, and the corresponding tilting plate in the automatic hopper is lifted by a cylinder, causing the rebar to fall into the corresponding hopper. Controlled by a hydraulic system, the line has a simple structure and is easy to operate, solving problems such as low automation, low work efficiency, and lack of worker safety.

[0004] However, this shearing line applies pressure via a cylinder during the shearing process, which, like most current shearing devices, uses unilateral force application. This leads to problems such as rebar misalignment and skewed cuts, as well as low cutting accuracy. Furthermore, this shearing device lacks a buffer mechanism, which cannot cushion the rigid impact generated during the cutting process, affecting the lifespan of the cutter. Therefore, improvements are needed.

[0005] To address this, a systematic combined shear line is proposed. Utility Model Content

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, this utility model embodiment provides a systematic combined shearing line, including a support plate 1 and a guide rail 4. A movable block 5 is slidably disposed on the upper surface of the guide rail 4. A frame plate 6 is mounted on the upper part of the movable block 5. A connecting plate 7 is slidably disposed on the inner side of the frame plate 6 in the vertical direction. A threaded rod 8 is mounted on the upper part of the connecting plate 7. A worm gear 9 is disposed in the middle of the top surface of the frame plate 6. A worm 11 is meshed on one side of the worm gear 9. A motor 10 is connected to the worm 11. The motor 10 is mounted on the frame plate 6. Rotating plates 12 are rotatably mounted on both sides of the connecting plate 7. A slide rail 13 is disposed on the inner side of the connecting plate 7. A sliding plate A14 is slidably disposed on the outer surface of the slide rail 13. A connecting post 15 is provided on the skateboard A14. A side plate 16 is installed on the end of the connecting post 15 away from the skateboard A14. A base plate 17 is installed directly below the rotating plate 12. A connecting plate A18 is hinged to the inside of the base plate 17 via a pivot. A skateboard B19 is slidably connected to the connecting post 15. Mounting plates 20 are respectively installed on the lower parts of the skateboard A14 and the skateboard B19. A cutter 21 is provided on the mounting plate 20. A connecting plate B22 is hinged to the upper center of the skateboard B19 via a pivot. A spring A23 is sleeved on the surface of the connecting post 15. Cylinders 24 are installed on the left and right sides below the connecting plate 7. The output end of the cylinder 24 is connected to the mounting plate 20.

[0028] In one embodiment, the worm gear 9 meshes with the worm 11, and the worm gear 9 is connected to the threaded rod 8 by a thread. During the rotation of the worm gear 9, it meshes with the thread on the surface of the threaded rod 8 through its internal threaded hole, and under the action of the thread, it drives the threaded rod 8 and the connecting plate 7 to rise along the frame plate 6.

[0029] In one embodiment, the frame plate 6 is provided with a sliding groove, and the two sides of the connecting plate 7 are equipped with protrusion structures adapted to the sliding groove. The protrusion structures are slidably disposed in the sliding groove. The upper part of the side plate 16 is hinged to the connecting plate A18 at the center position via a pivot, and the interior of the bottom plate 17 is hinged to the connecting plate B22 via a pivot. The cooperative design of the sliding groove and the protrusion structures can play a guiding role, ensuring that during the rotation of the worm gear 9, the connecting plate 7 below is stably raised by the threaded rod 8.

[0030] In one embodiment, I-beams 2 and guide seats 3 are respectively installed in an array on the upper part of the support plate 1. This can guide and fix the reinforcing bars, improving processing stability.

[0031] In one embodiment, one end of spring A23 is connected to slide plate B19, and the end of spring A23 away from slide plate B19 is connected to slide plate A14. Spring A23 drives slide plate B19 to slide on connecting post 15. During the shearing process, spring A23 is compressed, which also has a buffering effect and can effectively extend the life of cutter 21.

[0032] In one embodiment, a protruding plate 25 is mounted on the surface of the mounting plate 20, a sliding rod 26 is slidably mounted inside the protruding plate 25, a top plate 27 is mounted on the sliding rod 26, a pad plate 28 is mounted on the top plate 27, and a spring B29 is sleeved on the surface of the sliding rod 26. As the sliding plates A14 and B19 move, the pad plates 28 on both sides will first clamp the two sides of the reinforcing bar.

[0033] In one embodiment, one end of spring B29 is connected to top plate 27, and the end of spring B29 away from top plate 27 is connected to convex plate 25. Spring B29 drives top plate 27 to slide on convex plate 25 via slide rod 26. Under the action of spring B29, the rigid impact generated during the cutting of steel bars can be effectively buffered and absorbed, and the cutting stress can be distributed along the axial direction of steel bars to prevent the cutter 21 from cracking due to rigid impact.

[0034] In operation, the reinforcing bar is delivered to the cutting position through the perforation on the I-beam 2 on the support plate 1 and the guide seat 3. Then, the motor 10 starts and drives the worm gear 11 to rotate, which in turn drives the worm wheel 9 to rotate. Under the threaded engagement between the worm wheel 9 and the threaded rod 8, the connecting plate 7 descends to the cutting position, ready to cut the reinforcing bar. When cutting the reinforcing bar, the cylinder 24 is first started and drives the mounting plate 20 and the sliding plate B19 to slide along the slide rail 13. During this process, the connecting plate B22 will change its angle and position, and under the hinge coupling, the base plate 17 and the rotating plate 12 will rotate along the connecting plate 7. During this process, the connecting plate A18 will change its position simultaneously, and the side plate 16 and the sliding plate B19 will move synchronously in opposite directions. As the side plate 16 slides along the slide rail 13, the connecting column 15 will drive the sliding plate A14 on one side to slide synchronously, thereby driving the two sets of cutters 21 under the sliding plate A14 and the sliding plate B19 to move synchronously towards the axis of the reinforcing bar. During the continuous translation of 19, spring B29 is compressed. As the pressure increases, the two sets of cutters 21 will precisely cut the fixed steel bar in a centered manner, effectively avoiding problems such as steel bar displacement and skewed cut caused by traditional unilateral force application. This ensures that the cutting action is stable and reliable with high cutting accuracy. During this process, the rigid impact generated during steel bar cutting can be effectively buffered and absorbed under the action of spring B29, and the cutting stress is distributed along the steel bar axis to prevent the cutter 21 from cracking due to rigid impact. Spring A23 is also compressed during the cutting process, which can also play a buffering role and effectively extend the life of cutter 21. After the cutting work is completed, motor 10 drives worm 11 to rotate. With the cooperation of worm 11 and worm wheel 9, and through the threaded hole inside worm wheel 9, it meshes with the thread on the surface of threaded rod 8. Under the action of the thread, threaded rod 8 and connecting plate 7 are driven to rise along frame plate 6, which can drive the cutting surface of cutter 21 to gradually separate from the axis of steel bar. This allows the position of the cutting mechanism to be adjusted or separated for maintenance.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
