Description

Technical Field

[0001] This invention relates to the field of intelligent steel cutting technology, specifically to special steel cutting equipment. Background Technology

[0002] Special steels possess high strength, high hardness, excellent wear resistance, and fatigue resistance, and are widely used in key fields such as rail transportation, engineering machinery, energy equipment, aerospace, and high-end hydraulic components. Special steels are typical difficult-to-machine materials. Compared to ordinary carbon steel and alloy steel, they exhibit greater toughness, lower thermal conductivity, and a more significant work-hardening effect. In the processing of special steel parts, disc shears are commonly used for shearing operations. Due to the high tensile strength of special steel, the sheared area of ​​the plate readily forms a work-hardened layer under compression, resulting in significantly higher shear resistance than ordinary steel during shearing. The shear disc blades continuously endure substantial extrusive forces, cyclic impact loads, and continuous vibration.

[0003] Current special steel processing cutting equipment, when subjected to heavy-duty shearing operations on special steel for extended periods, experiences continuous alternating impact vibrations that constantly act on the locking nut. This can cause the locking nut to loosen and rotate, making it difficult to detect potential problems through manual visual inspection. As the preload of the locking nut decreases, the clamping force of the clamping wheel becomes insufficient and loosens, leading to the failure of the axial constraint on the shearing disc. Under alternating shearing loads, this results in axial movement, causing deviations in the pre-adjusted shearing gap and blade overlap between the upper and lower shearing discs, ultimately leading to a gradual deterioration in the processing quality of the workpiece's sheared cross-section.

[0004] To address the above issues, a special steel parts machining cutting equipment has been proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a special steel parts processing and cutting equipment. By using this device, the problem in the background mentioned above is solved: the locking nut is prone to rotation and loosening, and it is difficult to detect the hidden danger in time by relying on manual visual inspection. This causes the pre-adjusted shearing gap and blade overlap of the upper and lower shearing discs to deviate, resulting in a gradual deterioration of the processing quality of the workpiece shearing section.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A special steel parts processing and cutting equipment includes a base and an electric slide rail fixed to the surface of the base. A rotating component is provided on one side of the electric slide rail, and a shaft is provided on the opposite side of the rotating component. A connecting seat is fixedly installed at one end of the shaft. A shearing disc is slidably installed on the surface of the connecting seat, and a clamping wheel is also slidably installed on the surface of the connecting seat, and the clamping wheel is in contact with the shearing disc. A locking nut is threadedly connected to the surface of the connecting seat, and the locking nut is in contact with the clamping wheel. A fixed seat is provided at one end of the connecting seat. A moving component is fixedly installed inside the clamping wheel and is slidably connected to the connecting seat. A hydraulic cylinder is fixedly installed at one end of the fixed seat, and a laser sensor for detecting whether the moving component has shifted is also installed at one end of the fixed seat. A pusher for driving the moving component to reset is fixedly installed at the output end of the hydraulic cylinder.

[0008] Furthermore, the connecting seat includes a connecting plate and a fixed shaft fixed to one side of the connecting plate. The connecting plate is fixedly connected to the shaft. A pad is fixedly installed on the surface of the fixed shaft. The shearing plate, the pressure wheel, and the moving part are slidably connected to the fixed shaft. A threaded groove is opened on the surface of the fixed shaft, and the locking nut is threadedly connected to the threaded groove.

[0009] Furthermore, the fixing base includes a fixing plate and a fixing column fixed on one side of the fixing plate. The fixing column is slidably connected to the fixing shaft inside. Several bolts are threadedly connected to one side of the fixing plate and are threaded to the fixing shaft. The laser sensor is fixedly installed inside the fixing column.

[0010] Furthermore, the movable component includes a guide plate and connecting blocks fixed on both sides of the guide plate. The guide plate and the connecting blocks are slidably connected to the fixed shaft, and the connecting blocks are fixedly connected to the inner side of the pressure wheel.

[0011] Furthermore, the pushing component includes a pushing rod and a pushing disc fixed on the surface of the pushing rod. The pushing rod is fixedly connected to the output end of the hydraulic cylinder, and one end of the pushing rod is slidably connected to the inside of the fixed shaft. A tapered cylinder is also fixedly installed on the surface of the pushing rod.

[0012] Furthermore, several first L-shaped clamping plates are fixedly installed on one side of the guide plate.

[0013] Furthermore, the fixed shaft is provided with a locking element for guiding and locking the shear disc;

[0014] The locking component includes an annular frame plate and several guide rods that slide through one side of the annular frame plate. The annular frame plate is fixedly connected to the inside of the fixed shaft. A roller is fixedly installed at one end of the guide rod. The push rod contacts the roller. A limit plate is fixedly installed on the surface of the guide rod and is fixedly connected to the inside of the annular frame plate. A spring is fixedly installed on one side of the limit plate and is fixedly connected to the inside of the annular frame plate.

[0015] Furthermore, a second L-shaped card that is compatible with the first L-shaped card is fixedly installed on one side of the limiting plate, and the second L-shaped card is slidably connected to the annular frame plate.

[0016] Furthermore, the inner side of the shearing disc is provided with a slot that matches the guide rod.

[0017] Furthermore, the rotating component includes a housing and a rotating shaft rotatably connected inside the housing. The shaft is fixedly connected to the rotating shaft, and a first gear is fixedly mounted on the surface of the rotating shaft. Two first gears are meshed together. A motor is fixedly mounted on one side of the housing, and a second gear is fixedly mounted on the output end of the motor. The second gear is meshed with one of the first gears.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. By continuously monitoring the position of moving parts through laser sensors and utilizing the synchronous linkage between the moving parts and the clamping rollers, the axial displacement caused by the loosening of the locking nut can be indirectly identified. This can capture minor loosening hazards that are difficult to detect by manual visual inspection, and achieve early intelligent identification of potential hazards.

[0020] 2. The hydraulic cylinder drives the pushing and moving parts to drive the clamping wheel and shearing disc to achieve axial active reset, stabilize the shearing gap between the upper and lower shearing discs, effectively avoid defects such as workpiece burrs, sheet metal tearing, and partial shearing failure caused by subsequent axial displacement of the shearing disc, and intelligently correct the axial displacement of the shearing disc.

[0021] 3. The guide rod is embedded in the shearing disc slot to achieve circumferential limiting, which compensates for the fit clearance caused by long-term wear between the flat key and the keyway, and reduces the problem of circumferential impact jump and delayed rotation of the shearing disc during shearing.

[0022] 4. By relying on the interlocking of the first L-shaped clamping plate and the second L-shaped clamping plate, the axial movement of the guide plate is restricted, thereby locking the axial position of the moving part, the pressure wheel and the shearing plate, and preventing the shearing plate from shifting axially again after the locking nut loosens.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 1 and Figure 2As shown, the special steel parts processing and cutting equipment includes a base 1 and an electric slide rail 2 correspondingly fixed to the surface of the base 1. A rotating component 3 is provided on one side of the electric slide rail 2. The electric slide rail 2 can adjust the relative distance between the two sets of rotating components 3, allowing the shearing station spacing to be adjusted according to the width specifications of special steel parts, enabling the equipment to adapt to the processing of workpieces of various sizes and broadening its processing application range. A shaft 4 is correspondingly provided on one side of the rotating component 3. A connecting seat 5 is fixedly installed at one end of the shaft 4. A shearing disc 6 is slidably installed on the surface of the connecting seat 5. A pressure wheel 7 is also slidably installed on the surface of the connecting seat 5, and the pressure wheel 7 is in contact with the shearing disc 6. The torque output by the rotating component 3 is transmitted to the connecting seat 5 through the shaft 4, realizing... Stable power transmission; the connecting seat 5 serves as the assembly carrier for the shearing disc 6 and the clamping wheel 7. The clamping wheel 7 clamps and positions the special steel parts, while the shearing disc 6 shears and cuts the high-strength special steel. The cooperation between the two ensures stable conveying of the plate and prevents the workpiece from slipping or deviating during the shearing process. The connecting seat 5 is threaded with a locking nut 8, which is in contact with the clamping wheel 7. The locking nut 8 is installed on the connecting seat 5 through the threaded engagement and provides axial preload to clamp the clamping wheel 7 and the shearing disc 6, thereby achieving axial positioning of the shearing disc 6 and the clamping wheel 7, fixing the working position of the shearing disc 6, ensuring a stable shearing gap between the upper and lower shearing discs 6, and meeting the precision requirements of special steel shearing.

[0035] like Figure 3 As shown, the rotating component 3 includes a housing 31 and a rotating shaft 32 rotatably connected inside the housing 31. The shaft 4 is fixedly connected to the rotating shaft 32. A first gear 33 is fixedly mounted on the surface of the rotating shaft 32. Two first gears 33 are meshed together. A motor 34 is fixedly mounted on one side of the housing 31. A second gear 35 is fixedly mounted on the output end of the motor 34, and the second gear 35 is meshed with one of the first gears 33. The motor 34 outputs rotational power to drive the second gear 35 to rotate continuously. The second gear 35 drives the first gear 33 meshing with it to rotate. The first gear 33 drives the corresponding rotating shaft 32, shaft 4, connecting seat 5, shearing disc 6, and pressing wheel 7 to rotate synchronously. At the same time, the two meshing first gears 33 transmit torque, driving the rotating shaft 32 on the other side to rotate in the opposite direction, so that the upper and lower sets of shearing discs 6 and pressing wheels 7 rotate in opposite directions. The special steel parts are fed, clamped, and sheared by rotating in opposite directions.

[0036] To address the technical problem that the locking nut 8 is prone to loosening due to rotation, and that manual visual inspection is insufficient to detect potential issues in a timely manner, leading to deviations in the pre-adjusted shearing gap and blade overlap of the upper and lower shearing discs 6, and resulting in a gradual deterioration in the processing quality of the workpiece shearing section, the following preferred technical solution is provided:

[0037] like Figure 1 and Figure 2As shown, a fixed seat 9 is provided at one end of the connecting seat 5. A movable part 10 is fixedly installed inside the clamping wheel 7, and the movable part 10 is slidably connected to the connecting seat 5. A hydraulic cylinder 20 is fixedly installed at one end of the fixed seat 9. A laser sensor 30 for detecting whether the movable part 10 has shifted is also installed at one end of the fixed seat 9. The laser sensor 30 and the hydraulic cylinder 20 are electrically connected through a controller, which is existing technology and is not shown in the figure. The laser sensor 30 can continuously collect the position information of the movable part 10 in real time, accurately capture the slight axial displacement of the movable part 10, and indirectly identify the offset of the clamping wheel 7 caused by the loosening of the locking nut 8. It can identify manual... The system can detect subtle loosening faults that are difficult to detect during routine inspections, enabling early detection of faults. The hydraulic cylinder 20, as the axial reset power source, is arranged on the fixed base 9 with a compact structure. It provides controllable linear driving force for the reset and correction of the shearing disc 6 and the clamping wheel 7. The output end of the hydraulic cylinder 20 is fixedly installed with a pusher 40 for driving the moving part 10 to reset. When the position needs to be corrected, the hydraulic cylinder 20 drives the pusher 40 to contact and push the moving part 10, which drives the clamping wheel 7 and the shearing disc 6 to move axially and reset. This quickly adjusts the offset shearing disc 6 to the standard working position, restores the standard shearing gap, and avoids continuous shearing that causes workpiece scrap and blade damage.

[0038] During the operation of the special steel parts processing and cutting equipment, the operator can adjust the electric slide rail 2 on the surface of the base 1 according to the width of the workpiece to be processed, change the relative distance between the two sets of rotating parts 3, and adapt to the shearing processing needs of special steel parts of different width specifications. When the equipment is shearing, the rotating part 3 outputs rotational power, drives the shaft 4 and the connecting seat 5 to rotate synchronously, and drives the shearing disc 6 and the clamping wheel 7 mounted on the connecting seat 5 to rotate together. The clamping wheel 7 and the shearing disc 6 cooperate to clamp the special steel parts and complete the shearing and cutting processing. Under normal shearing conditions, the hydraulic cylinder 20 on the fixed seat 9 maintains the initial position, and the pushing part 40 at the output end of the hydraulic cylinder 20 is separated from the moving part 10 inside the clamping wheel 7.

[0039] Due to the high tensile strength of special steel, a work-hardened layer easily forms in the shearing area, resulting in high shear resistance. Long-term alternating impact loads continuously act on the locking nut 8, making it prone to loosening. After the preload of the locking nut 8 decays, the pressure wheel 7 and shearing disc 6 shift axially along the connecting seat 5. The moving part 10 built into the pressure wheel 7 moves axially in sync with the pressure wheel 7. The laser sensor 30 installed at the fixed seat 9 continuously monitors the position of the moving part 10 in real time, indirectly determining the loosening state of the locking nut 8 based on the displacement change of the moving part 10. When the laser sensor 30 detects that the displacement of the moving part 10 reaches the system's preset threshold, the control system determines that the locking nut 8 has loosened. The equipment will not stop immediately, continuing to complete the current special steel shearing operation.

[0040] After the current workpiece shearing is completed and the workpiece conveying intermittent window period is entered, the control system starts the correction process. The controller drives the hydraulic cylinder 20 to move, which in turn drives the pusher 40 to move axially. The pusher 40 contacts the moving part 10 and applies axial thrust. The moving part 10 is forced to move the pressure wheel 7 axially. The pressure wheel 7 further pushes the shearing disc 6 to slide along the connecting seat 5, so that the pressure wheel 7 and the shearing disc 6 are reset to the preset standard working position, and the axial offset of the shearing disc 6 is intelligently corrected.

[0041] Therefore, by continuously monitoring the position of the moving part 10 with the laser sensor 30 and taking advantage of the synchronous linkage between the moving part 10 and the pressure wheel 7, the axial displacement caused by the loosening of the locking nut 8 can be indirectly identified. This can capture minor loosening hazards that are difficult to detect by manual visual inspection, and achieve early hazard identification. The hydraulic cylinder 20 drives the pusher 40 and the moving part 10 to drive the pressure wheel 7 and the shearing disc 6 to achieve axial active reset, stabilize the shearing gap between the upper and lower shearing discs 6, and effectively avoid defects such as workpiece burrs, sheet tearing, and partial shearing failure caused by the axial displacement of the shearing disc 6. This also avoids shearing failure and the problem of shearing disc 6 blade collision and breakage.

[0042] like Figure 4 and Figure 5 As shown, the connecting seat 5 includes a connecting plate 51 and a fixed shaft 52 fixed to one side of the connecting plate 51. The connecting plate 51 is fixedly connected to the shaft 4. A pad 53 is fixedly installed on the surface of the fixed shaft 52. The shearing disc 6, the pressure wheel 7, and the moving part 10 are slidably connected to the fixed shaft 52. By fixing a flat key on the surface of the shaft 4, and by engaging the keyway on the inner side of the shearing disc 6 with the flat key, circumferential positioning and torque transmission between the shaft 4 and the shearing disc 6 are achieved, so that the shaft 4 can stably drive the shearing disc 6 to rotate synchronously, ensuring reliable power transmission for shearing operations. A threaded groove 54 is provided on the surface of the fixed shaft 52. The locking nut 8 is threadedly connected to the threaded groove 54. The locking nut 8 is threadedly assembled through the threaded groove 54. The locking nut 8 generates axial preload by tightening the thread, pressing the pressure wheel 7 from the outside, and cooperating with the inner pad 53 to achieve bidirectional axial clamping and positioning of the shearing disc 6 and the pressure wheel 7.

[0043] like Figure 4As shown, the fixing base 9 includes a fixing plate 91 and a fixing column 92 fixed to one side of the fixing plate 91. The fixing column 92 is slidably connected to the fixing shaft 52. Several bolts 93 are threadedly connected to one side of the fixing plate 91 and are threaded to the fixing shaft 52. The fixing plate 91 is fastened to the end face of the fixing shaft 52 by multiple sets of bolts 93. The multi-point bolt 93 locking method distributes the force evenly. Under the condition of continuous vibration caused by special steel shearing, the fixing base 9 is not easy to loosen or deflect. The laser sensor 30 is fixedly installed inside the fixing column 92, and the laser sensor 30 is positioned and supported by the fixing column 92. During equipment operation, the fixed column 92 rotates synchronously with the fixed shaft 52. The laser sensor 30 maintains the same rotation reference as the fixed shaft 52, the pressure wheel 7, and the moving part 10, and continuously detects the axial position of the moving part 10 in real time, continuously collecting displacement data to determine the loosening status of the locking nut 8. When it is necessary to disassemble or repair the laser sensor 30, the hydraulic cylinder 20, or the pushing part 40, simply remove the bolt 93 to pull the fixed seat 9 out from the end of the fixed shaft 52. The fixed column 92 relies on the guiding effect of sliding cooperation with the fixed shaft 52, and the disassembly and assembly process is not prone to displacement or jamming.

[0044] like Figure 6 and Figure 7 As shown, the movable component 10 includes a guide plate 101 and connecting blocks 102 fixed on both sides of the guide plate 101. The combination structure of the guide plate 101 and the connecting blocks 102 on both sides is adopted. The guide plate 101 and the connecting blocks 102 are simultaneously slidably engaged with the fixed shaft 52 to form a double-support sliding guide structure, which effectively improves the coaxiality of the movable component 10 on the fixed shaft 52, prevents the movable component 10 from tilting or jamming, and ensures smooth axial movement. The guide plate 101 and the connecting blocks 102 are slidably connected to the fixed shaft 52 respectively. The connecting blocks 102 are fixedly connected to the inner side of the pressure wheel 7. The connecting blocks 102 are fixedly set on both sides of the guide plate 101 and connected to the inner side of the pressure wheel 7, realizing the rigid connection between the movable component 10 and the pressure wheel 7. When the pressure wheel 7 generates axial displacement, it can synchronously drive the movable component 10 to move together. The displacement of the pressure wheel 7 can be completely and accurately transmitted to the movable component 10, ensuring that the displacement data collected by the laser sensor 30 can truly reflect the offset of the pressure wheel 7 and improve the accuracy of loosening detection.

[0045] like Figure 7 and Figure 8As shown, the pushing component 40 includes a pushing rod 401 and a pushing disk 402 fixed to the surface of the pushing rod 401. The pushing disk 402 uses its disc-shaped end face as the pressure-bearing contact surface. During the calibration and resetting operation, the pushing disk 402 contacts the guide disk 101 surface to transmit force. The force-bearing area is larger and the pressure is lower, which can avoid stress concentration causing local pressure damage to the guide disk 101. The thrust transmission is more stable and uniform, ensuring the smooth axial resetting of the clamping wheel 7 and the shearing disk 6. The pushing rod 401 is fixedly connected to the output end of the hydraulic cylinder 20, and one end of the pushing rod 401 is connected to the fixed shaft 52. The sliding connection is provided, and a tapered cylinder 403 is also fixedly installed on the surface of the push rod 401. When the laser sensor 30 detects that the displacement of the guide plate 101 reaches a preset threshold, the system starts the correction process during the workpiece conveying interval. The hydraulic cylinder 20 extends and drives the push rod 401 to slide axially along the inside of the fixed shaft 52. The push rod 401 drives the push plate 402 to move forward synchronously. The push plate 402 abuts against the guide plate 101 and applies axial thrust, driving the guide plate 101, the pressure wheel 7 and the shearing plate 6 to move axially synchronously until they are reset to the standard working position.

[0046] To address the technical problem of continuous friction and wear between the flat key on the surface of the fixed shaft 52 and the keyway inside the shearing disk 6, leading to a gradual increase in the clearance between them; and the circumferential impact and vibration of the shearing disk 6 during shearing, resulting in instantaneous delayed rotation and deterioration of the workpiece cross-sectional quality, the following preferred technical solution is provided:

[0047] like Figure 7 and Figure 9 As shown, several first L-shaped clamping plates 50 are fixedly installed on one side of the guide plate 101. A locking element 60 for guiding and locking the shearing disc 6 is provided inside the fixed shaft 52. The locking element 60 includes an annular frame plate 601 and several guide rods 602 that slide through one side of the annular frame plate 601. The annular frame plate 601 is fixedly connected to the inside of the fixed shaft 52. A roller 603 is fixedly installed at one end of each guide rod 602. The push rod 401 contacts the roller 603, and the roller 603 rolls against the inclined surface of the conical cylinder 403, converting sliding friction into rolling friction and effectively reducing the radial movement of the conical cylinder 403 driving the guide rod 602. The frictional resistance during movement reduces component wear, ensures smooth extension and retraction of the guide rod 602, and prevents jamming failure. A limit plate 604 is fixedly installed on the surface of the guide rod 602, and the limit plate 604 is fixedly connected to the inside of the annular frame plate 601. A spring 605 is fixedly installed on one side of the limit plate 604, and the spring 605 is fixedly connected to the inside of the annular frame plate 601. Under long-term heavy-load shearing conditions of special steel, the flat key on the surface of the fixed shaft 52 and the keyway inside the shearing disc 6 continuously rub and wear, and the clearance between the two gradually increases. At the moment of shearing, the shearing disc 6 generates circumferential impact and jump, resulting in instantaneous delayed rotation, which causes the workpiece cross-sectional quality to deteriorate.

[0048] When the laser sensor 30 detects that the pressure wheel 7 is loose to the threshold, the hydraulic cylinder 20 extends, driving the push rod 401 and the push plate 402 to move forward. The push plate 402 pushes the guide plate 101, causing the pressure wheel 7 and the shearing plate 6 to move axially along the fixed shaft 52, thus completing the axial position reset of the shearing plate 6.

[0049] After the shearing disc 6 is axially aligned, the hydraulic cylinder 20 drives the push rod 401 to retract, and the push disc 402 separates from the guide disc 101. During the continuous retraction of the push rod 401, the tapered cylinder 403 moves axially. The inclined surface of the tapered cylinder 403 presses against the roller 603, pushing the guide rod 602 to slide radially outward. During the movement of the guide rod 602, the limiting plate 604 compresses the spring 605. The outer end of the guide rod 602 extends out and inserts into the inner side of the shearing disc 6. After the guide rod 602 is embedded in the inner side of the shearing disc 6, it constrains the circumferential movement of the shearing disc 6 relative to the fixed shaft 52, eliminating the impact and vibration caused by the wear gap of the flat key.

[0050] When it is necessary to release the lock, the hydraulic cylinder 20 extends again, the conical cylinder 403 moves forward to disengage from the roller 603, the spring 605 releases its elastic force to push the limit plate 604 to reset, the guide rod 602 retracts radially, the guide rod 602 exits the inner side of the shearing disc 6, the circumferential limit is released, and the subsequent normal rotation and shearing of the shearing disc 6 is not affected.

[0051] Therefore, after the key and keyway wear and produce gaps, the guide rod 602 is inserted into the inside of the shearing disk 6 to limit the circumferential impact jump of the shearing disk 6 during the shearing moment, eliminate the lag rotation phenomenon of the shearing disk 6, stabilize the quality of the workpiece shearing section, reduce burrs and tearing defects, and rely on the different strokes of the push rod 401 to complete the two processes of axial reset of the shearing disk 6 and circumferential locking of the shearing disk 6.

[0052] A second L-shaped clamping plate 606, which is adapted to the first L-shaped clamping plate 50, is fixedly installed on one side of the limiting plate 604. The second L-shaped clamping plate 606 is slidably connected to the annular frame plate 601. When the inclined surface of the conical cylinder 403 squeezes the roller 603, it drives the guide rod 602 and the limiting plate 604 to move radially outward. The limiting plate 604 simultaneously drives the second L-shaped clamping plate 606 to slide outward along the annular frame plate 601. The second L-shaped clamping plate 606 continues to move radially with the limiting plate 604 and finally engages with the first L-shaped clamping plate 50 at the guide plate 101. Relying on the meshing cooperation of the first L-shaped clamping plate 50 and the second L-shaped clamping plate 606, the guide plate 101 is restricted from continuing to move axially, thereby locking the axial position of the guide plate 101, the pressure wheel 7 and the shearing plate 6, and preventing the shearing plate 6 from shifting axially again after the locking nut 8 loosens.

[0053] Hydraulic cylinder 20 extends again, conical cylinder 403 moves forward and disengages from roller 603, spring 605 releases elastic force to pull limit plate 604 back to its original position, second L-shaped clamping plate 606 then retracts radially and disengages from first L-shaped clamping plate 50, releasing the axial limit of guide plate 101, and the equipment resumes normal rotation and shearing conditions.

[0054] like Figure 4 and Figure 7 As shown, the inner side of the shearing disc 6 is provided with a slot 61 that matches the guide rod 602. The slot 61 has a chamfered structure at the opening, which has a good guiding effect and can effectively offset the slight alignment deviation that exists during the extension of the guide rod 602, avoid rigid alignment and jamming, reduce the failure rate of the mechanism, and allow the guide rod 602 to be smoothly and quickly embedded into the slot 61, improving the stability and success rate of the locking and correction action. The slot 61 provides a precise limiting position for the extension and locking of the guide rod 602, so that the guide rod 602 can be accurately embedded into the slot 61 after extension, realizing precise circumferential locking of the shearing disc 6, effectively offsetting the fit clearance caused by the wear of the flat key and keyway, preventing the circumferential impact jump and instantaneous lag rotation of the shearing disc 6 during shearing, ensuring the smooth shearing process of special steel parts and stabilizing the machining accuracy of the workpiece shearing section.
