Description

Technical Field

[0001] This invention relates to the field of metal shearing technology, and in particular to a shearing device and method for linear steel used in the production of bowl racks. Background Technology

[0002] In the manufacturing process of metal products such as bowl racks, it is usually necessary to continuously cut linear steel to meet the needs of subsequent forming or assembly. In the existing technology, flying shear devices are often used to cut the moving linear steel, which improves the quality of end cutting and also improves processing efficiency.

[0003] Chinese Patent Publication No. CN118976935B discloses a shearing device for cutting round steel and metal plates, including a base. A storage box is slidably connected to the inner side of the base, and a placement plate is fixedly connected to the top of the base. A connecting rod is fixedly connected to the top of the placement plate, and a push rod is rotatably connected to the outer side of the top of the connecting rod via a bearing. A shearing blade is rotatably connected to the outer side of the placement plate via a bearing. The end of the push rod away from the connecting rod is rotatably connected to the shearing blade via a bearing. By setting a fixing mechanism, when the shearing blade moves downward under the push rod, a mechanism on one side will drive a pressure component to move downward as well, allowing the pressure component to contact the steel first and fix the steel in place. This ensures that the steel will not move during the shearing process and that the sheared material will not have defects.

[0004] When existing flying shears continuously cut linear steel, the lack of effective constraint and synchronous limiting on the discharge side causes the linear steel to sway or shift at the moment of cutting, resulting in large deformation of the cross section and affecting its direct use in subsequent processes. Meanwhile, the finished linear steel segments after shearing release internal stress in an unconstrained state, making them prone to swaying, bending or colliding with each other, resulting in surface damage and unstable shape. In addition, when temporarily clamping the linear steel to improve shearing stability, it is difficult to achieve speed matching between the clamping mechanism and the continuously running linear steel. If the clamping speed is too fast, it may cause dragging, thus affecting the fixed length accuracy. If the clamping speed is too slow, it may hinder the discharge and induce bending, making it difficult to guarantee the overall processing quality. On the other hand, the finished linear steel segments after shearing fall and slide due to inertia, which can easily cause hard collisions with equipment and damage the surface. Moreover, the accumulation pattern is relatively messy, which requires manual sorting and collection, thus limiting production efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a linear steel shearing device and method for bowl rack manufacturing. Addressing issues such as swaying, stress release bounce, and disordered finished product collection during continuous shearing of linear steel, a comprehensive solution is constructed, comprising a guiding clamping mechanism, a linkage triggering mechanism, a flying shearing mechanism, and a material distribution structure working in tandem. By radially limiting the linear steel at the moment of shearing and achieving synchronous sliding in the same direction as its movement, the clamping action and the feeding process are matched. Simultaneously, the automatic triggering and release of the clamping is achieved through the cooperation of the arc-shaped protrusion in the shearing mechanism and the second roller. Combined with the continuous flow distribution of the collection trough, rectification trough, distribution trough, and diversion trough within the material bin, shearing, limiting, and collection form a coherent action chain. This not only helps reduce the risk of shearing deformation and finished product bounce but also improves overall operational coordination without complex control, demonstrating the comprehensive improvement brought about by structural linkage.

[0006] This invention is achieved using the following technical solution: A shearing device for linear steel in the manufacture of bowl racks includes a shearing mechanism, in which linear steel is threaded. The shearing mechanism has movable arc-shaped protrusions. A material box is fixed at the outlet of the shearing mechanism, and a first guide groove is provided at the inlet of the material box. The linear steel slides through the first guide groove and extends into the material box. Two sets of clamping plates are slidably arranged relative to each other within the first guide groove, located on opposite sides of the linear steel. A first reset rod is provided on the clamping plate away from the linear steel, and a second reset rod is provided near the end of the first reset rod. One end of the second reset rod abuts against the first reset rod and is fitted with a displacement component, while the other end extends outside the material box. When the shearing mechanism shears the linear steel, the arc-shaped protrusions of the shearing mechanism push against the second reset rod. The first reset rod drives the two sets of clamping plates to temporarily restrict the radial movement of the linear steel before automatically disengaging, reducing the risk of bending or scratches at the ends of the linear steel due to stress oscillation during shearing.

[0007] Furthermore, two sets of guide frames are slidably arranged inside the first guide groove, and the sliding direction of the two sets of guide frames is perpendicular to the moving direction of the linear steel.

[0010] Furthermore, a material-forming trough is formed inside the material-forming box and in the direction of the linear steel's movement. The material-forming trough includes a receiving trough with a Y-shaped cross-section and two diversion troughs with a herringbone cross-section. The bottom end of the receiving trough is connected to the diversion trough, and the bottom end of the diversion trough is connected to the diversion trough, which has an inverted Y-shaped cross-section. The bottom end of the diversion trough is connected to the two diversion troughs. A herringbone plate is set inside the diversion trough, and the herringbone plate is rotatably installed by a pin. The pointed tops of the herringbone plate alternately abut against the inner walls of the two sides of the diversion trough, and the bottom feet of the herringbone plate alternately abut against the inner walls of the two sides of the diversion trough.

[0011] Furthermore, the shearing mechanism includes a bracket fixed to the top of the support plate, a motor fixed on the bracket, and an eccentric wheel installed at the output end of the motor; two sets of guide rails are fixed parallel to each other on the bracket located on one side of the eccentric wheel, and a flying shear bracket is slidably mounted on the guide rails; the flying shear bracket includes a first slider and a second slider, the first slider is slidably mounted on the top guide rail, and the second slider is slidably mounted on the bottom guide rail; a longitudinal rod is fixedly connected between the two sliders, and a guide rail is fixed on the longitudinal rod on one side relative to the eccentric wheel, and the flying shear slider is slidably mounted on the guide rail; the flying shear slider is mounted on the edge of the eccentric wheel via a rotating rod, a pressure plate is fixed at the bottom end of the flying shear slider, and an arc-shaped protrusion is fixed on the side of the flying shear slider near the material box; a shearing assembly is installed inside the second slider, and a linear steel bar passes through the second slider and through the shearing assembly.

[0012] Furthermore, the shearing assembly includes a second slider with a cavity structure.

[0014] Furthermore, a buffer pad is provided on the inner wall of the receiving groove, and the buffer pad is located in the extension direction of the linear steel section.

[0015] A method using the aforementioned linear steel shearing device for manufacturing bowl racks includes the following steps: S1, Material Feeding The linear steel is guided along the feeding direction of the device, so that the linear steel passes through the shearing assembly inside the second slider and is located between the moving blade and the fixed blade, while the linear steel is continuously conveyed towards the material box. S2, Linkage Clamping The motor is started, which drives the eccentric wheel to rotate. The eccentric wheel drives the flying shear slider to reciprocate. During the movement of the flying shear slider, the arc-shaped protrusion contacts the second roller. The second roller drives the contact rod to move. The contact rod pushes the wedge plate to act on the first roller, so that the two sets of guide frames are relatively close and drive the clamping plate to clamp and limit the linear steel. The clamping plate slides synchronously with the linear steel under the guidance of the guide rod. S3, Cut execution As the flying shear slide moves, it applies downward pressure through the pressure plate. The pressure plate drives the shearing rod to move downward, causing the moving blade to move towards the fixed blade, thus shearing the linear steel located between the moving blade and the fixed blade to complete the fixed-length cutting. S4, Reset and Resume After shearing is completed, the arc-shaped protrusion disengages from the second roller. Under the action of the reset spring, the recovery spring, and the return spring, the contact rod, wedge plate, guide frame, and clamping plate are reset, releasing the clamping of the linear steel. At the same time, under the action of the return spring, the shearing rod drives the moving blade to reset, allowing the linear steel to continue to be conveyed forward and enter the next cycle. S5. Finished Product Collection After being sheared, the linear steel segments move along the direction of the material box and enter the receiving trough. Then, after being guided by the straightening trough, they enter the distribution trough. Under the swinging action of the herringbone plate, the linear steel segments are alternately guided into the distribution troughs on both sides by the bottom feet, so as to achieve orderly distribution and collection of the finished linear steel segments after shearing.

[0016] The beneficial effects of this invention include: 1. This invention addresses the problems of swaying and deviation, stress release bounce, and disordered finished product collection that easily occur during continuous shearing of linear steel. It constructs an overall solution that coordinates a guiding clamping mechanism, a linkage triggering mechanism, a flying shearing mechanism, and a material diversion structure. By implementing radial limiting on the linear steel at the moment of shearing and achieving synchronous sliding in the same direction as its movement, the clamping action and the feeding process are matched. At the same time, the automatic triggering and release of clamping is achieved by the cooperation of the arc-shaped protrusion in the shearing mechanism and the second roller. Combined with the continuous flow distribution of the collection trough, rectification trough, material distribution trough, and diversion trough in the material box, the shearing, limiting, and collection form a coherent action chain. This not only helps to reduce the risk of shearing deformation and finished product bounce, but also improves the overall operational coordination without the need for complex control, presenting a comprehensive improvement brought about by structural linkage.

[0017] 2. In this invention, through the two sets of guide frames and their internal clamping plates and guide rod structures set in the first guide groove, the guide frames slide relative to each other along the direction perpendicular to the movement of the linear steel under external triggering, thereby driving the clamping plate to radially limit the moving linear steel. At the same time, the clamping plate can slide synchronously with the linear steel along the guide rod, so that the clamping process moves in the same direction as the linear steel in the axial direction. This avoids dragging or obstruction caused by mismatch in the speed of the clamping parts, and provides stable support for the linear steel at the moment of shearing, reducing cross-sectional deformation. Furthermore, at the moment of shearing, the clamping plate still constrains the finished section, which can weaken the bounce phenomenon caused by stress release, reduce the probability of bending and collision damage, and improve the shearing quality and subsequent use stability.

[0018] 3. In this invention, a linkage displacement assembly consisting of a contact rod, a restoring spring, a wedge plate, a first roller, and a second roller is installed in the guide hole and the second guide groove. The position change of the arc-shaped protrusion during the shearing stroke drives the second roller, which in turn pushes the contact rod to drive the wedge plate to apply force to the first roller, thus converting the motion of the shearing mechanism into the clamping action of the guide frame, achieving the time-sequential linkage of clamping and shearing. After shearing is completed, the restoring spring and the return spring work together to automatically reset each component. The entire process does not require additional power input or control intervention, and while maintaining a relatively simple structure, it achieves continuous cycle of action, which helps to improve the stability and response consistency of the device operation.

[0019] 4. In this invention, a multi-stage guiding structure consisting of a collection trough, a rectification trough, a distribution trough, and a diversion trough is constructed inside the material bin. A swingable herringbone plate is installed in the distribution trough, so that the sheared linear steel segments are gradually gathered, guided, and distributed after entering the collection channel. The herringbone plate swings alternately under the impact of the finished product, and its bottom feet alternately guide the linear steel segments into the diversion troughs on both sides, realizing automatic diversion and collection. Compared with the disorderly stacking method, it can reduce the risk of surface damage caused by the sliding and impact of the finished product, while reducing the need for manual sorting, making the collection process more orderly and smooth, and improving the overall production efficiency and finished product consistency to a certain extent.

[0024] Example 1:

[0025] like Figure 1-6As shown, a linear steel shearing device for manufacturing bowl racks includes a shearing mechanism, in which a linear steel 13 is inserted. The shearing mechanism has movable arc-shaped protrusions 24. A material box 27 is fixed at the outlet of the shearing mechanism. A first guide groove 28 is provided at the inlet of the material box 27. The linear steel 13 slides through the first guide groove 28 and extends into the material box 27. Two sets of clamping plates 30 are slidably arranged relative to each other within the first guide groove 28, with the two sets of clamping plates 30 located on opposite sides of the linear steel 13. The clamping plates 30 are positioned away from the linear steel 13. A first reset rod is provided on one side of the steel section 13, and a second reset rod is provided near the end of the first reset rod. One end of the second reset rod abuts against the first reset rod and is equipped with a displacement component, while the other end of the second reset rod extends to the outside of the material box 27. When the shearing mechanism shears the steel section, the arc-shaped protrusion 24 of the shearing mechanism pushes against the second reset rod. The first reset rod drives the two sets of clamping plates 30 to temporarily restrict the radial movement of the steel section 13 and then automatically disengages, reducing the risk of bending at the end of the steel section or scratches caused by stress swing at the end after shearing.

[0026] It should be noted that a storage box 16 is provided below the material bin 27; a power mechanism is provided in front of the shearing mechanism. The power mechanism is used to convey the linear steel 13. The power mechanism is existing technology and will not be described in detail here.

[0027] This invention addresses the problems of swaying and deviation, stress release bounce, and disordered finished product collection that easily occur during the continuous shearing of linear steel 13. It constructs an integrated solution that coordinates a guiding clamping mechanism, a linkage triggering mechanism, a flying shearing mechanism, and a material distribution structure. By radially limiting the linear steel 13 at the moment of shearing and achieving synchronous sliding in the same direction as its movement, the clamping action and the feeding process are matched. Simultaneously, the automatic triggering and release of the clamping is achieved through the cooperation of the arc-shaped protrusion 24 and the second roller 41 in the shearing mechanism. Combined with the continuous flow distribution of the receiving groove 46, the rectifying groove 45, the distributing groove 47, and the diversion groove 48 within the material box 27, the shearing, limiting, and collection form a coherent action chain. This not only helps reduce the risk of shearing deformation and finished product bounce but also improves the overall operational coordination without complex control, demonstrating the comprehensive improvement brought about by structural linkage.

[0028] Furthermore, two sets of guide frames 29 are slidably arranged inside the first guide groove 28, and the sliding direction of the two sets of guide frames 29 is perpendicular to the moving direction of the linear steel 13; a guide rod 31 is fixed in the inner opening 42 of the guide frame 29, the axis of the guide rod 31 is parallel to the moving direction of the linear steel 13, and a clamping plate 30 and a return spring 32 are slidably sleeved on the guide rod 31, with the clamping plate 30 located closer to the shearing mechanism relative to the return spring 32; one end of the first return rod is fixedly connected to the guide frame 29, and the first return rod is located on the side away from the clamping plate 30.

[0029] Two sets of guide frames 29 are slidably arranged in the first guide groove 28. The sliding direction of the guide frames 29 is perpendicular to the moving direction of the linear steel 13. Under the drive of the external triggering mechanism, the two sets of guide frames 29 can move closer to each other along the moving direction perpendicular to the linear steel 13, thereby driving the clamping plates 30 in their respective inner openings 42 to move synchronously towards both sides of the linear steel 13. This achieves radial temporary limiting of the continuously moving linear steel 13, effectively preventing the linear steel 13 from shaking or shifting due to uneven force at the moment of shearing, and reducing the risk of large deformation of the cross section. After clamping, the clamping plate 30 can also provide radial constraint on the finished linear steel section at the moment the linear steel 13 is cut, so as to prevent it from bouncing due to the instantaneous release of internal stress, thereby preventing the finished end from swinging, bending deformation or even collision damage with the surrounding structure, which helps to ensure the surface quality and overall shape of the finished linear steel section. Since the linear steel 13 continues to move axially during clamping, the clamping plate 30 is driven by the linear steel 13 and slides freely along the guide rod 31 fixed in the inner opening 42 of the guide frame 29 in a direction parallel to the movement of the linear steel 13. This allows the clamping plate 30 and the linear steel 13 to maintain axial speed synchronization. This prevents the clamping parts from moving too fast, which would drag the material and increase the feeding speed, resulting in inaccurate output length. It also prevents the clamping parts from moving too slowly, which would create an obstacle at the output end and cause bending. Thus, a balance is achieved between radial fixation and axial synchronization, which better ensures the dimensional accuracy and finished product quality of the linear steel 13 during the shearing process. In addition, the return spring 32, which is also sleeved on the guide rod 31, is located on the side of the clamping plate 30 away from the shearing mechanism. It can provide axial return force to the clamping plate 30 after the clamping action is released, so that it returns to the initial position before the next clamping, ensuring the continuous and reliable operation of the device.

[0030] Furthermore, a guide hole 33 is formed on the side of the first guide groove 28 away from the opening, and a second guide groove 37 is formed at the end of the guide hole 33 away from the first guide groove 28; the second guide groove 37 is perpendicular to the axis of the guide hole 33, and one end of the second guide groove 37 passes through the material box 27 and the opening faces the shearing mechanism; the first reset rod includes a guide rod 34 and a return spring 35; the guide rod 34 is slidably inserted in the guide hole 33, one end of the guide rod 34 is fixedly connected to the guide frame 29, and the other end of the guide rod 34 is fixedly provided with a first roller 36, which is located in the second guide groove 37, and a limiting ring is fixedly provided on the guide rod 34 near the first roller 36; the diameter of the guide hole 33 at the end away from the first guide groove 28 is expanded to form a receiving groove; the return spring 35 is sleeved on the guide rod 34, and the return spring 35 is located in the receiving groove, with both ends of the return spring 35 abutting against the limiting ring and the bottom of the receiving groove, respectively.

[0031] A guide hole 33 is opened in the first guide groove 28 on the side away from the opening, and a second guide groove 37 perpendicular to its axis is opened at the far end of the guide hole 33. One end of the second guide groove 37 passes through the material box 27 and opens towards the shearing mechanism. The above structures together constitute the movement channel of the first reset rod. The first reset rod includes a guide rod 34 and a return spring 35. The guide rod 34 is slidably inserted in the guide hole 33. One end is fixedly connected to the guide frame 29, and the other end is fixedly provided with a first roller 36. The first roller 36 is located in the second guide groove 37. When an external trigger from the shearing mechanism side enters along the second guide groove 37 and presses against the first roller 36, it can push the guide rod 34 to slide axially along the guide hole 33, thereby driving the guide frame 29 to move in the direction of the linear steel 13 in the first guide groove 28, and driving the clamping plate 30 to complete the radial clamping action of the linear steel 13. The limiting ring fixed on the guide rod 34 and the receiving groove formed by the expansion of the far end of the guide hole 33 together define the installation position of the return spring 35. The return spring 35 is sleeved on the guide rod 34 and its two ends abut against the limiting ring and the bottom of the receiving groove, respectively. When the external trigger is removed, the elastic restoring force of the return spring 35 pushes the guide rod 34 to reverse and reset, driving the guide frame 29 and the clamping plate 30 back to the initial position, releasing the radial constraint on the linear steel 13, so that the device can automatically return to the standby state after completing one shearing and clamping cycle, and prepare for the next trigger. This helps to ensure the reliability of the device's operation and the stability of the cycle time during continuous production.

[0032] Furthermore, the second guide groove 37 has a receiving cavity 43 and a displacement cavity 44. The displacement assembly is located in the displacement cavity 44, which is connected to the guide hole 33. The receiving cavity 43 is opened with an expanded diameter. The second reset rod includes a contact rod 38 and a recovery spring 39. The contact rod 38 is slidably sleeved inside the second guide groove 37. A second roller 41 is fixed at the end of the contact rod 38 located outside the material box 27. A limiting baffle is fixed on the contact rod 38 located inside the receiving cavity 43. The recovery spring 39 is sleeved on the contact rod 38 and located in the receiving cavity 43. One end of the recovery spring 39 abuts against the limiting baffle, and the other end of the recovery spring 39 abuts against the bottom of the receiving cavity 43 located near the end of the displacement cavity 44. The displacement assembly includes a first roller 36 and a wedge plate 40 fixed at the end of the contact rod 38. The inclined surface of the wedge plate 40 abuts against the first roller 36. The top of the inclined surface of the wedge plate 40 is located near the end of the second roller 41.

[0033] The second guide groove 37 is provided with a receiving cavity 43 and a displacement cavity 44. The displacement cavity 44 is connected to the guide hole 33. The receiving cavity 43 is an enlarged diameter structure, which provides space for the installation and movement of the second reset rod. The second reset rod includes a contact rod 38 and a reset spring 39. The contact rod 38 is slidably sleeved inside the second guide groove 37. The end of the contact rod 38 located outside the material box 27 is fixed with a second roller 41. When the arc-shaped protrusion 24 on the shearing mechanism side moves to the opening of the material box 27 with the shearing action, it presses against the second roller 41 and pushes the contact rod 38 to slide along the second guide groove 37 toward the displacement cavity 44. A wedge plate 40 is fixed to the end of the contact rod 38 near the displacement cavity 44. The top of the inclined surface of the wedge plate 40 is located near the end of the second roller 41. When the contact rod 38 is pushed in, the inclined surface of the wedge plate 40 continuously presses against the first roller 36 in the displacement cavity 44, converting the axial displacement of the contact rod 38 into the vertical displacement of the guide rod 34, thereby driving the guide frame 29 to move the clamping plate 30 toward the linear steel 13 to complete the radial clamping, realizing the motion transmission between the arc-shaped protrusion 24 triggering and the clamping action. The restoring spring 39 inside the receiving cavity 43 is sleeved on the contact rod 38, with its two ends abutting against the limiting baffle on the contact rod 38 and the bottom of the receiving cavity 43 near the displacement cavity 44, respectively. When the arc-shaped protrusion 24 is reset and disengaged from the second roller 41 with the shearing mechanism, the elastic restoring force of the restoring spring 39 pushes the contact rod 38 back in the opposite direction. The wedge plate 40 then removes its pressure on the first roller 36. In conjunction with the return spring 35, the guide rod 34 and the guide frame 29 are reset. The clamping plate 30 releases the linear steel 13 simultaneously. The entire transmission mechanism completes automatic reset without additional drive, enabling the device to continuously cycle with the shearing rhythm, which helps to improve the coordination and stability of the operation in the continuous production process.

[0034] Furthermore, a material-forming trough is formed inside the material-forming box 27 and in the extending direction of the linear steel 13. The material-forming trough includes a receiving trough 46 with a Y-shaped cross-section and two diversion troughs 48 with a herringbone cross-section. A rectifying trough 45 is connected to the bottom end of the receiving trough 46, and a material-distributing trough 47 is provided at the bottom end of the rectifying trough 45. The material-distributing trough 47 has an inverted Y-shaped cross-section. Two diversion troughs 48 are connected to the bottom end of the material-distributing trough 47. A herringbone plate 49 is provided inside the material-distributing trough 47 and is rotatably installed by a pin. The pointed tops of the herringbone plate 49 alternately abut against the inner walls of the two sides of the material-distributing trough 47, and the bottom feet 50 of the herringbone plate 49 alternately abut against the inner walls of the two sides of the diversion trough 48.

[0035] The material collection box 27 has a material collection trough inside along the extension direction of the linear steel 13. The material collection trough is formed by the sequential connection of the collection trough 46, the straightening trough 45, the material distribution trough 47 and two distribution troughs 48 to form a complete collection and distribution channel. The receiving trough 46 has a Y-shaped cross-section structure with its opening facing the incoming direction of the linear steel 13. It can initially guide and gather the finished linear steel segments that are rushed in by inertia after shearing, reducing the risk of surface damage caused by the impact of the finished linear steel segments. The bottom end of the receiving trough 46 is connected to the rectifier trough 45. After being gathered by the receiving trough 46, the finished linear steel segments enter the rectifier trough 45. Under the constraint of the rectifier trough 45, the posture is further regulated, reducing the deflection and scattering of the finished products during the sliding process, which helps to improve the neatness of the subsequent collection. The bottom of the rectifier 45 is connected to the distribution trough 47, which has an inverted Y-shaped cross-section structure to collect and guide the finished linear steel segments from the rectifier 45. The herringbone plate 49, which is rotatably installed inside the material distribution trough 47, swings freely through a pin. Its pointed tip alternately abuts against the inner walls of the two sides of the material distribution trough 47 under the impact of the finished linear steel section. The bottom feet 50 on both sides alternately abut against the inner walls of the two diversion troughs 48, thereby alternately pushing the finished linear steel section into the two diversion troughs 48 to achieve automatic diversion and collection. The above structure does not require additional drive. After the finished product is injected, the herringbone plate 49 is driven by gravity to swing periodically, which distributes the finished linear steel segments generated by continuous shearing to the two side diversion channels 48 in a relatively even manner. This reduces the need for finished product accumulation and manual sorting to a certain extent, and helps to improve the overall efficiency of the production and storage process.

[0036] More importantly, the herringbone plate 49 is driven to change direction by gravity of the finished linear steel on both sides. When the finished linear steel exhibits abnormal posture (such as tilting when entering), the bottom foot 50 will lift the end of the finished linear steel that has come into contact first, and wait for the other end to fall down before entering the diversion groove 48 together, thus standardizing the posture of the finished linear steel and facilitating the smooth transfer of the next process.

[0037] Furthermore, the shearing mechanism includes a bracket 15 fixed to the top of the support plate 11, a motor 17 fixed on the bracket 15, and an eccentric wheel 18 mounted on the output end of the motor 17; two sets of guide rails 19 are fixed parallel to each other on the bracket 15 located on one side of the eccentric wheel 18, and a flying shear bracket is slidably mounted on the guide rails 19; the flying shear bracket includes a first slider 20 and a second slider 22, the first slider 20 being slidably mounted on the top guide rail, and the second slider 22 being slidably mounted on the bottom guide rail. A longitudinal rod 21 is fixedly connected between the two sliders. A guide rail is fixed on the side of the longitudinal rod 21 opposite to the eccentric wheel 18. A flying shear slider 23 is slidably sleeved on the guide rail. The flying shear slider 23 is installed at the edge of the eccentric wheel 18 through a rotating rod. A pressure plate is fixed at the bottom end of the flying shear slider 23. An arc-shaped protrusion 24 is fixed on the side of the flying shear slider 23 near the material box 27. A shearing assembly is set inside the second slider 22. A linear steel 13 passes through the second slider 22 and passes through the shearing assembly.

[0038] It should be noted that a pre-processing unit 14 is set in the shearing assembly for straightening and judging the coiled linear steel; a support foot 12 is fixed at the bottom of the support plate 11; a discharge port 26 is set on the side of the linear steel 13 near the material box 27, and the cut small section of linear steel is discharged from the discharge port 26.

[0039] The shearing mechanism has a bracket 15 fixed on the top of the support plate 11 as the main frame. A motor 17 is fixed on the bracket 15. An eccentric wheel 18 is installed at the output end of the motor 17. The motor 17 drives the eccentric wheel 18 to rotate continuously, providing a cyclic power source for the entire shearing mechanism. Two sets of guide rails 19 are fixed in parallel on the bracket 15. The flying shear bracket is slidably mounted on the upper and lower sets of guide rails 19 by the first slider 20 at the top and the second slider 22 at the bottom. The two sliders are fixedly connected by a longitudinal rod 21, forming an overall flying shear bracket structure that can slide stably along the guide rails 19. The double guide rail constraint helps to reduce the deflection and sway of the flying shear bracket in high-speed reciprocating motion and improves the stability of the shearing action. A guide rail is fixed on the longitudinal rod 21 on one side relative to the eccentric wheel 18. A flying shear slider 23 is slidably sleeved on the guide rail. The flying shear slider 23 is installed at the edge of the eccentric wheel 18 through a rotating rod. When the eccentric wheel 18 rotates, the flying shear slider 23 decomposes the rotational motion of the eccentric wheel 18 into the reciprocating translational motion of the flying shear bracket along the direction of the guide rail 19 and the lifting and lowering motion of the flying shear slider 23 along the direction of the guide rail under the constraint of the guide rail. This drives the flying shear bracket and the flying shear slider 23 to work together to achieve the shearing stroke of the moving blade relative to the fixed blade. A pressure plate is fixed at the bottom of the flying shear slider 23, which can apply pressure to the linear steel 13 during the shearing stroke. It works with the shearing component inside the second slider 22 to complete the precise cutting of the linear steel 13 that passes through the second slider 22. An arc-shaped protrusion 24 is fixed on the side of the flying shear slider 23 near the material box 27. The arc-shaped protrusion 24 moves synchronously with the flying shear slider 23. During the shearing stroke, it presses against the second roller 41 on the side of the material box 27 at the appropriate time, triggering the clamping mechanism to implement radial limit on the linear steel 13. After the shearing is completed, the arc-shaped protrusion 24 is reset and disengaged with the flying shear slider 23. The clamping mechanism automatically releases the clamp, so that the shearing action and the clamping action are naturally linked in time, without the need for additional control intervention. This helps to simplify the overall control logic and improve the operation coordination of the device.

[0040] Furthermore, the shearing assembly includes a second slider 22 with a cavity structure. A guide groove is formed on the top of the second slider 22, and a shearing rod is slidably installed inside the guide groove. One end of the shearing rod extends to the outside of the second slider 22 and is fixedly mounted with a pressure plate 25. A movable blade is fixedly mounted at the other end of the guide rod, and a fixed blade is fixedly mounted at the bottom of the second slider 22 below the movable blade. A linear steel 13 passes between the movable blade and the fixed blade. Wing plates are fixedly mounted on both sides of the shearing rod. A limiting guide rod is fixed between the wing plates and the bottom of the inner cavity of the second slider 22. A spring is sleeved on the limiting guide rod, and the two ends of the spring abut against the wing plates and the bottom of the inner cavity of the second slider 22, respectively.

[0041] The second slider 22 has a cavity structure with a guide groove at the top. The shearing rod is slidably installed in the guide groove. One end of the shearing rod extends to the outside of the second slider 22 and is fixed with a pressure plate 25 to receive the pressure input from the pressure plate. A moving blade is fixed at the other end of the shearing rod, and a fixed blade is fixed at the bottom of the second slider 22 located directly below the moving blade. The linear steel 13 continuously passes between the moving blade and the fixed blade. When the pressure plate 25 is pressed down by the driving force of the pressure plate, the shearing rod drives the moving blade to move towards the fixed blade. The moving blade and the fixed blade cooperate to complete the shearing action of the linear steel 13, realizing the fixed-length cutting of the linear steel 13. Wing plates are fixed on both sides of the shearing rod. A limiting guide rod is fixed between the wing plate and the bottom of the inner cavity of the second slider 22. The limiting guide rod constrains the up and down sliding direction of the wing plate, which can prevent the shearing rod from deflecting or shaking during the movement to a certain extent, and helps to ensure the alignment accuracy between the moving blade and the fixed blade. A return spring is fitted on the limit guide rod. The two ends of the return spring abut against the wing plate and the bottom of the inner cavity of the second slider 22, respectively. When the external pressure is released, the elastic restoring force of the return spring pushes the wing plate and the shearing rod upward to reset, so that the moving blade retracts from the fixed blade and restores the initial distance, preparing for the next shearing action. This allows the shearing mechanism to continuously reciprocate with the drive cycle, which helps to ensure the reliability of the device's operation and the consistency of shearing during continuous production.

[0042] Furthermore, fastening grooves are respectively provided on the clamping plate 30, and the two sets of fastening grooves are relative to the linear steel 13.

[0043] Fastening grooves are respectively opened on the clamping plate 30. The two sets of fastening grooves are symmetrically arranged relative to the linear steel 13. When the two sets of guide frames 29 drive the clamping plate 30 to move closer to the linear steel 13, the linear steel 13 can be embedded in the fastening grooves on both sides. The groove walls of the fastening grooves form a multi-directional wrapping limit on the linear steel 13. Compared with planar clamping, the constraint on the linear steel 13 in the radial direction is more sufficient, which helps to further reduce the deflection or displacement of the linear steel 13 due to force at the moment of shearing. At the same time, it can also disperse the contact stress of the clamping surface to a certain extent, reduce the possibility of the clamping plate 30 causing indentation or damage to the surface of the linear steel 13, and help to ensure the surface quality of the finished linear steel section.

[0044] Furthermore, a buffer pad is provided on the inner wall of the receiving groove 46, and the buffer pad is located in the extending direction of the moving linear steel 13.

[0045] A buffer pad is provided on the inner wall of the receiving trough 46 in the direction of the extension of the linear steel 13. When the sheared finished linear steel segment rushes into the receiving trough 46 along this direction with inertia, it first contacts the buffer pad. The elastic deformation of the buffer pad can absorb part of the impact kinetic energy, reduce the impact force of the hard collision between the end of the finished linear steel segment and the inner wall of the receiving trough 46, thereby reducing the risk of surface damage such as crushing, denting or scratching at the end of the finished product. At the same time, the buffer pad can also play a certain role in decelerating and stabilizing the finished linear steel segment, so that it maintains a relatively stable posture before entering the rectifier trough 45, which helps to improve the smoothness of the subsequent rectification and diversion links.

[0046] Example 2:

[0047] The method using the linear steel shearing device for manufacturing bowl racks includes the following steps: S1, Material Feeding The linear steel 13 is introduced along the feeding direction of the device, so that the linear steel 13 passes through the shearing assembly inside the second slider 22 and is located between the moving blade and the fixed blade, while the linear steel 13 is continuously conveyed towards the material box 27. S2, Linkage Clamping The motor 17 is started, which drives the eccentric wheel 18 to rotate. The eccentric wheel 18 drives the flying shear slider 23 to reciprocate. During the movement of the flying shear slider 23, the arc-shaped protrusion 24 contacts the second roller 41. The second roller 41 drives the contact rod 38 to move. The contact rod 38 pushes the wedge plate 40 to act on the first roller 36, so that the two sets of guide frames 29 are relatively close and drive the clamping plate 30 to clamp and limit the linear steel 13. The clamping plate 30 slides synchronously with the linear steel 13 under the guidance of the guide rod 31. S3, Cut execution As the flying shear slider 23 moves, it applies downward pressure through the pressure plate 25. The pressure plate 25 drives the shearing rod to move downward, causing the moving blade to move towards the fixed blade, and shearing the linear steel 13 located between the moving blade and the fixed blade to complete the fixed-length cutting. S4, Reset and Resume After shearing is completed, the arc-shaped protrusion 24 disengages from the second roller 41. Under the action of the reset spring 32, the recovery spring 39, and the return spring 35, the contact rod 38, the wedge plate 40, the guide frame 29, and the clamping plate 30 are reset, releasing the clamping of the linear steel 13. At the same time, under the action of the return spring, the shearing rod drives the moving blade to reset, allowing the linear steel 13 to continue to be conveyed forward and enter the next cycle. S5. Finished Product Collection After being sheared, the linear steel segments move along the direction of the material box 27 and enter the collection trough 46. After being guided by the straightening trough 45, they enter the distribution trough 47. Under the swinging action of the herringbone plate 49, the base foot 50 alternately guides the linear steel segments into the two side distribution troughs 48, realizing the orderly distribution and collection of the finished linear steel segments after shearing.
