Description

TECHNICAL FIELD

[0001] The present application relates to the field of metal workpiece shearing, in particular to a steel grating side shearing machine and method. BACKGROUND

[0002] Steel grating, also known as grid, is a kind of steel product formed by cross arrangement and welding of flat steel and cross bar. After welding, the excess part of the cross bar on both sides of the steel grating needs to be sheared for further edge processing. There are machines for shearing the excess part of the cross bar. However, the prior art has the following problems: 1. The existing machine is provided with a pushing mechanism for pushing the steel grating, a positioning mechanism for positioning the steel grating, and a shearing mechanism for shearing the cross bar. The positioning mechanism is used to position the steel grating according to the position of the cross bar to be sheared, so as to cooperate with the shearing mechanism to accurately shear the cross bar. However, the pushing mechanism and the positioning mechanism are separately arranged, which has high manufacturing cost; 2. In the production of steel grating, the cross bars used are of fixed length. If steel gratings of different widths are produced, different numbers of steel gratings and cross bars need to be welded together, and then the excess cross bars on both sides of the steel grating are sheared off. Therefore, when shearing the cross bars of steel gratings of different widths, the shearing position is different, and the shearing position of the shearing mechanism in the prior art cannot be adjusted, which has limitations in use. SUMMARY

[0003] The purpose of the present application is to provide a steel grating side shearing machine with a pushing assembly for pushing and positioning the steel grating and a shearing assembly for shearing the cross bar, which has the advantages of less installation workload and convenient adjustment.

[0004] The technical solution adopted by the present application is as follows: a steel grating side shearing machine, comprising a pushing assembly and a shearing assembly, the pushing assembly comprising a first moving unit moving along the Y direction, a lifting unit moving along the Z direction, and a clamping unit for clamping the steel grating, the lifting unit being fixedly installed on the moving end of the first moving unit, and the clamping unit being fixedly installed on the moving end of the lifting unit.

[0005] The shearing assembly comprises a second moving unit and a shearing unit for shearing the cross bar, the shearing unit being arranged on the second moving unit, and the second moving unit being used to adjust the position of the shearing unit along the X direction.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. During processing, the clamping unit can clamp the steel grating and push it forward through the first moving unit. After the crossbar to be cut is pushed to the cutting unit, the clamping unit can press the steel grating through the lifting unit, so that the cutting unit can cut the crossbar. This structure does not require an additional positioning mechanism and can cooperate with the cutting mechanism to accurately cut the crossbar, resulting in low manufacturing cost; 2. When processing steel gratings of different widths, the position of the cutting unit can be adjusted according to the width of the steel grating to be processed through the second moving unit, thereby adapting to the current width of the steel grating to be processed and improving applicability.

[0007] In a preferred embodiment of the present invention, the shearing unit includes an upper shearing part, a lower shearing part, and a sensor. The sensor is used to identify the distance from the blade of the shearing unit to the outermost flat bar of the steel grating. The lower shearing part cooperates with the upper shearing part to shear the crossbar.

[0008] The second moving unit is used to move the shearing unit along the X direction by a displacement amount corresponding to the distance identified by the sensor.

[0009] Beneficial effects: When shearing steel grating, the sensor can identify the distance from the shearing unit's blade to the outermost flat bar of the steel grating. Then, the second moving unit moves the shearing unit along the X direction with a displacement corresponding to the distance identified by the sensor. This structure can reduce reliance on manual labor and improve production efficiency.

[0010] In a preferred embodiment of the present invention, the shearing unit includes a base for mounting the lower shearing part, and a first pad and a second pad are fixed on the base;

[0011] The lower shearing section includes a lower power source, a lower blade holder, a lower blade head, and a lower support plate for supporting the steel grating. The lower blade holder has a second mounting area for mounting the lower blade head. The lower power source is used to drive the lower blade holder and the lower blade head. The lower support plate is mounted on the base via a second pad. The lower blade holder and the lower blade head are positioned between the first pad and the second pad.

[0012] Beneficial effects: In this solution, the lower support plate serves to support the steel grating, while the second pad serves to install the lower support plate, so that the lower support plate can achieve its effect. At the same time, the first and second pads can limit and guide the lower cutter holder and the lower cutter head between them, thereby strengthening the installation strength of the lower cutter head and improving the shearing stability.

[0013] In a preferred embodiment of the present invention, the upper shearing part includes an upper power source, an upper pressure block, and an upper cutter head. The inner side of the lower end of the upper pressure block is provided with a pressing protrusion for pressing the steel grating. The outer side of the pressing protrusion is provided with a first mounting area for mounting the upper cutter head. The upper end face of the upper cutter head abuts against the lower end face of the upper pressure block, and the inner side face of the upper cutter head abuts against the outer side face of the pressing protrusion. The outer side of the upper cutter head is provided with a first notch for avoiding the lower shearing part. The upper power source is used to drive the upper pressure block and the upper cutter head to move downward and abut against the steel grating.

[0014] Beneficial effects: The upper end of the upper cutter head is installed in the first installation area, and the two sides of the upper cutter head abut against the two sides of the first installation area respectively. When shearing the crossbar, the lower shearing part can move into the first notch to avoid the upper cutter head. This structure is conducive to the stable and smooth shearing work of the upper and lower cutter heads. At the same time, the upper pressure block plays the role of pressing the steel grating, which is conducive to stabilizing the steel grating and thus carrying out shearing. The upper cutter head cooperates with the lower shearing part to shear the crossbar.

[0015] In a preferred embodiment of the present invention, the second moving unit includes a lead screw, a second power source, a nut mounting seat disposed on the lead screw, a second slide rail disposed on the frame, and a slider disposed on the second slide rail. The axial direction of the lead screw and the length direction of the second slide rail are perpendicular to the direction in which the steel grating is pushed. The shearing unit is connected to the nut mounting seat and the slider respectively. The second power source is used to drive the nut mounting seat to move along the lead screw, and the nut mounting seat is used to drive the shearing unit and the slider to move.

[0016] Beneficial effects: When processing steel gratings of different widths, the position of the shearing unit can be adjusted by turning on the second power source, thereby improving the applicability of the shearing unit. After adjustment, the nut mounting seat and the shearing unit can be locked in the current position, which facilitates the shearing unit to process steel gratings of the same width within a certain period of time. In addition, the slide rail and slider guide the movement of the nut mounting seat and the shearing unit, improving the accuracy of the shearing unit's movement along the screw axis.

[0017] In a preferred embodiment of the present invention, the clamping unit includes a fixed clamping block and a movable clamping block that moves relative to the fixed clamping block. Both the fixed clamping block and the movable clamping block are disposed at the moving end of the lifting unit. The lower ends of both the fixed clamping block and the movable clamping block are provided with a first slot for engaging with the flat steel. The movable clamping block is provided with a second slot for engaging with the crossbar on the side near the fixed plate.

[0018] Beneficial effects: Through the cooperation of the first and second slots, the crossbars and flat bars of the steel grating are clamped and limited in two directions at the same time, making the clamping of the steel grating more stable; after the shearing is completed, the fixed clamping block and the movable clamping block are released, the lifting unit lifts the fixed clamping block and the movable clamping block, the first moving unit is reset, and the next feeding can be carried out. The automated pushing and pressing improves the processing efficiency.

[0019] In a preferred embodiment of the present invention, the clamping unit further includes a vertical mounting plate, which is fixedly mounted on the moving end of the lifting unit. A push cylinder is fixedly mounted on the vertical mounting plate, and a fixed plate is fixedly mounted on the vertical mounting plate. The fixed clamping block is fixedly mounted on the fixed plate, and a movable plate is fixedly mounted on the moving end of the push cylinder. The movable clamping block is fixedly connected to the movable plate. After the movable plate moves toward the fixed plate, it clamps two adjacent crossbars of the steel grating between the movable clamping block and the fixed clamping block.

[0020] Beneficial effects: By setting up a push cylinder to move the movable clamping block, the fixed clamping block and the movable clamping block are controlled to clamp or release two adjacent crossbars. Since the movable clamping block can be adjusted within a certain range, the device can adapt to various specifications of steel grating.

[0021] In a preferred embodiment of the present invention, a frame is also included, on which multiple sets of transverse mounting parts are installed at intervals. Each set of transverse mounting parts includes two mounting rods. Each set of transverse mounting parts is provided with a set of pressing rollers. The number of pressing rollers in each set is two. The two pressing rollers are symmetrically arranged on both sides of the steel grating along the transport direction of the steel grating. The pressing rollers are used to press the steel grating.

[0022] Beneficial effects: By using multiple sets of guide rollers to limit the steel grating at multiple points, the stability of the steel grating during pushing and shearing can be further increased, and the shearing accuracy can be improved.

[0023] In a preferred embodiment of the present invention, the pressing roller includes a second plate, a height adjusting rod, a third plate, a width adjusting rod, and a roller body. The second plate is slidably mounted on the corresponding mounting rod and locked in place on the mounting rod by a first screw. One end of the height adjusting rod is fixedly mounted on the second plate. The third plate is slidably mounted on the height adjusting rod. The width adjusting rod is slidably mounted on the third plate. The roller body is rotatably mounted on the width adjusting rod. The third plate has a third notch on the outer side of both the height adjusting rod and the width adjusting rod. The corresponding first screw passes through the corresponding third notch to lock the position of the third plate on the height adjusting rod and the width adjusting rod, respectively.

[0024] Beneficial effects: The position of the second plate can be adjusted by loosening the first screw, thereby adjusting the lateral position of the roller over a wide range. The height of the roller can be adjusted vertically by moving the third plate along the height adjustment rod. The lateral position of the roller can be adjusted within a small range by moving the third plate along the width adjustment rod without disassembling the second plate, which can adapt to steel gratings of different specifications. The clamping force is greater by setting the third notch, making the installation of the third plate more stable.

[0025] This invention also provides a method for side-shearing steel grating, applied to the aforementioned pushing device, comprising the following steps:

[0026] S1: The steel grating is placed on the frame, and the lifting unit drives the clamping unit to move down to clamp the steel grating;

[0027] S2: The lifting unit drives the clamping unit and the steel grating to move up, and the first moving unit moves toward the shearing assembly to push the steel grating. After the crossbar to be sheared is pushed to the shearing unit, the lifting unit drives the clamping unit to move down to press the steel grating.

[0028] S3: The second moving unit adjusts the position of the two shearing units according to the width of the steel grating to be processed, so that both ends of the crossbar to be sheared enter the two shearing units respectively, and then the shearing units shear the crossbar.

[0029] Alternatively, the two ends of the crossbar to be cut are directly pushed into two cutting units, which cut the crossbar.

[0030] S4: After the above shearing is completed, the pushing component repeatedly pushes the steel grating forward, so that the next batch of crossbars to be sheared is directly pushed into the two shearing units. The shearing units then repeatedly shear the crossbars to be sheared until the steel grating is fully processed.

[0031] S5: After the steel grating is fully processed, the pushing component releases the steel grating and moves away from the shearing component to push the next steel grating.

[0032] Compared with existing technologies, the advantages of this method are: 1. The pushing component can both clamp and push the steel grating through the gap of the shearing crossbars, and also press the steel grating during the shearing of the crossbars; 2. The shearing component can adjust the position of the two shearing units according to the width of the steel grating to be processed at the beginning of processing to accommodate steel gratings of different widths. After adjustment, no further adjustment is needed when processing the same steel grating or processing two steel gratings of the same width. Attached Figure Description

[0042] The implementation examples are basically as follows Figures 1-6 As shown: A steel grating side-shearing machine includes a frame 1, on which a pushing assembly 7 and a shearing assembly are provided. The pushing assembly 7 includes a first moving unit 701 that moves along the Y direction, a lifting unit 7021 that moves along the Z direction, and a clamping unit 702 for clamping steel grating 8. The lifting unit 7021 is fixedly installed on the moving end of the first moving unit 701, and the clamping unit 702 is fixedly installed on the moving end of the lifting unit 7021. Specifically, the clamping unit 702 is used to clamp the steel grating 8, and the first moving unit 701 is used to push the clamping unit 702 and the steel grating 8 forward. After the first moving unit 701 pushes the crossbar to be sheared to the shearing unit, the lifting unit 7021 presses the clamping unit 702 and the steel grating 8 downward, so that the shearing unit shears the crossbar to be sheared. The shearing assembly includes a second moving unit 5 and a shearing unit for shearing the crossbar. The shearing unit is disposed on the second moving unit 5, and the second moving unit 5 is used to adjust the position of the shearing unit along the X direction.

[0043] like Figure 1 and 3As shown, the first moving unit 701 includes a first mounting frame 7011, a drive motor 7013, and gears. A first slide rail 7012 is fixedly connected to the frame 1. The drive motor 7013 is mounted on the first mounting frame 7011. The gears are fixedly connected to the output shaft of the drive motor 7013. The first mounting frame 7011 is slidably connected to the first slide rail 7012. A rack is fixedly connected to the frame 1. The gears and racks mesh. When the drive motor 7013 drives the gears to rotate, the first mounting frame 7011 moves along the first slide rail 7012. Furthermore, by setting multiple sets of first mounting frames 7011, drive motors 7013, and gears, mounted on a single set of racks and first slide rails 7012, since each set of pushing components 7 is independently driven by gears, the movement of each set of pushing components 7 does not affect each other. They can be pushed synchronously or asynchronously.

[0044] In this embodiment, the lifting unit 7021 is located in the middle of the first mounting frame 7011 and is driven by a lifting cylinder to move the clamping unit 702 up and down. The clamping unit 702 includes a vertical mounting plate 7022 and a fixed clamping block 7028 and a movable clamping block 7026 for clamping the steel grating 8. The vertical mounting plate 7022 is fixed to the moving end of the mounting lifting cylinder. The vertical mounting plate 7022 is provided with a pushing cylinder 7023 and two symmetrically arranged guide rods 7024. The fixed plate 7027 is fixedly installed on the guide rods 7024. The movable plate 7025 has a through hole for sliding connection with the guide rods 7024. The movable plate 7025 is fixedly installed at the moving end of the pushing cylinder 7023. The movable plate 7025 is fixedly connected to the movable clamping block 7026. In addition, the lower ends of the fixed clamping block 7028 and the movable clamping block 7026 are provided with a first slot 7029 for engaging with the flat steel. The movable clamping block 7026 has a second slot 7030 for engaging with the crossbar on the side near the fixed plate 7027. The second slot 7030 is a V-shaped slot. When pushing the steel grating 8, the cylinder 7023 drives the movable plate 7025 to move toward the fixed plate 7027, clamping the two adjacent crossbars of the steel grating 8 between the movable clamping block 7026 and the fixed clamping block 7028. In addition, after welding, the crossbars on the steel grating 8 may bend or shift within a certain range. By setting a V-groove, the misaligned crossbars are guided and locked, and the V-groove can adapt to crossbars of different diameters within a certain range.

[0045] like Figure 1 and 2As shown, multiple sets of transverse mounting sections are installed at intervals on the frame 1. Each set of transverse mounting sections includes two mounting rods 101. Each transverse mounting section is equipped with a set of pressure rollers 102. Each set of pressure rollers 102 consists of two rollers, symmetrically arranged on both sides of the steel grating 8 along the transport direction of the steel grating 8. Specifically, each pressure roller 102 includes a second plate 1021, a height adjusting rod 1022, a third plate 1023, a width adjusting rod 1024, and a roller 1025. The second plate 1021 is slidably mounted on the corresponding mounting rod 101 and locked to the mounting rod 101 by a first screw. One end of the height adjusting rod 1022 is fixedly mounted on the second plate 1021. The third plate 1023 is slidably mounted on the height adjusting rod 1022. The width adjusting rod 1024 is slidably mounted on the third plate 1023. The roller 1025 is rotatably mounted on the width adjusting rod 1025. On the section rod 1024, and with the outer surface of the roller body 1025 abutting against the upper end face of the steel grating 8, the third plate body 1023 has a third notch on the outer side of both the height adjusting rod 1022 and the width adjusting rod 1024. The corresponding first screws are inserted into the corresponding third notches, respectively locking the position of the third plate body 1023 on the height adjusting rod 1022 and the width adjusting rod 1024. After the first screws are tightened, due to the certain elasticity of the material, the friction between the third plate body 1023 and the height adjusting rod 1022 and the width adjusting rod 1024 makes the installation more stable.

[0046] In this embodiment, a guide plate 103 is provided on the mounting rod 101. The guide plate 103 is located below the corresponding pressing roller 102. The guide plate 103 includes a first block 1031, a second block 1032, and a third block 1033. The first block 1031 is fixed to the mounting rod 101 by a second screw. The second block 1032 is fixedly installed on the upper end of the first block 1031. The third block 1033 is fixedly installed on the inner side of the first block 1031. During processing, two adjacent flat steel bars of the steel grating 8 abut against the side wall of the second block 1032. The upper end face of the third block 1033 is used to support the flat steel bars. Furthermore, the guide plate 103 and the aforementioned pressing roller 102 are mounted on the corresponding mounting rod 101 by a second screw. Their positions can be adjusted by turning the first or second screw according to the width of the steel grating 8.

[0047] like Figure 2As shown, the second block 1032 and the third block 1033 are provided with inclined surfaces to guide the flat steel. When the flat steel is slightly tilted, it will be guided onto the guide plate 103. In addition, the clamping roller 102 and the guide plate 103 are mounted on the corresponding mounting rod 101 by screws, and their positions can be adjusted according to the width of the steel grating 8. During shearing, the first slot 7029, the second block 1032 and the third block 1033 limit the flat steel in the X direction, the second slot 7030 limits the crossbar in the Y direction, and the multiple clamping rollers 102 limit the steel grating 8 as a whole in the horizontal direction. The above-mentioned limiting forms a clamping and fixing of the steel grating 8, replacing the existing clamps.

[0048] like Figure 1 , 4 As shown in Figures 5 and 6, the shearing assembly specifically includes two shearing units for shearing crossbars. The two shearing units are symmetrically arranged on both sides of the steel grating 8. A second moving unit 5 is provided at the bottom of each shearing unit. The second moving unit 5 is used to adjust the position of the shearing unit according to the width of the steel grating 8 to be processed. In this embodiment, the side of the shearing unit facing the steel grating 8 is the inner side, and the opposite side is the outer side. Furthermore, the side of the shearing unit facing the steel grating 8 to be sheared is the front side, and the opposite side is the rear side. The orientation and position of the following structures and components are consistent with the above. Specifically, both shearing units are mounted on the frame 1. Each shearing unit includes a second mounting frame 2. The second mounting frame 2 is provided with an upper shearing part 3, a lower shearing part 4, and a sensor 6. The sensor 6 is used to identify the distance from the shearing unit's blade to the outermost flat bar of the steel grating 8. The lower shearing part 4 cooperates with the upper shearing part 3 to shear the crossbar. The second moving unit 5 is used to move the shearing unit along the X direction with a displacement corresponding to the distance identified by the sensor 6. This structure reduces reliance on manual labor and improves production efficiency.

[0049] In this embodiment, the second mounting frame 2 includes a vertical support plate 202, a top plate 203 for mounting the upper shearing part 3, a base 201 for mounting the lower shearing part 4, and two support rods 204. The vertical support plate 202 is disposed on the base 201, the support rods 204 are disposed on the side opposite to the vertical support plate 202, and the top plate 203 is disposed on the vertical support plate 202. Specifically, the upper shearing part 3 includes an upper power source 301, an upper pressure block 302, and an upper cutter head 303. The upper power source 301 is a hydraulic cylinder and is disposed above the top plate 203. The upper cutter head 303 and the upper pressure block 302 are disposed below the top plate 203. The output shaft of the upper power source 301 passes through the top plate 203 to drive the upper pressure block 302 and the upper cutter head 303. A pressing protrusion for pressing the steel grating 8 is provided on the inner side of the lower end of the upper pressure block 302. The outer side is provided with a first mounting area 305 for mounting the upper cutter head 303. The upper end face of the upper cutter head 303 is fixed to the lower end face of the upper pressure block 302. The inner side of the upper cutter head 303 is fixed to the outer side of the pressing protrusion. A first notch 304 is provided on the outer side of the upper cutter head 303 to avoid the lower shearing part 4. The upper power source 301 is used to drive the upper pressure block 302 to press down the steel grating 8. The upper cutter head 303 cooperates with the lower shearing part 4 to shear the crossbar.

[0050] Furthermore, a first pad 2011 and a second pad 2012 are fixed on the base 201. The lower shearing part 4 includes a lower power source 401, a lower blade holder 402, a lower blade head 403, and a lower support plate 404 for supporting the steel grating 8. The lower power source 401 is also a hydraulic cylinder and is located below the base 201. The lower blade holder 402, the lower blade head 403, and the lower support plate 404 are located above the base 201. The output shaft of the lower power source 401 passes through the base 201 to drive the lower blade holder 402 and the lower blade head 403 to cooperate with the upper blade head 303 to shear the crossbar. Specifically, the lower support plate 404 is disposed on the inner side of the base 201 via the second pad 2012. The lower cutter holder 402 and the lower cutter head 403 are disposed between the first pad 2011 and the second pad 2012. The lower cutter holder 402 has a second mounting area 406 for mounting the lower cutter head 403. A connecting protrusion is provided on the outer side of the lower end of the lower cutter head 403. The second mounting area 406 includes a connecting groove and a connecting surface. After the lower cutter head 403 is installed, the connecting groove connects with the connecting protrusion, the connecting surface abuts against the outer surface of the lower cutter head 403, and the inner surface of the lower cutter head 403 abuts against the outer surface of the second pad 2012.

[0051] Furthermore, the lower shearing unit 4 also includes a connecting plate 405 disposed on the opposite side of the vertical support plate 202. The connecting plate 405 serves to connect the first pad 2011 and the second pad 2012. The shearing unit also includes a waste discharge section, which includes a dropping block 2013 and a collecting trough 2014. The dropping block 2013 is disposed on the outside of the base 201 via the first pad 2011, and the collecting trough 2014 is disposed outside the base 201. The lower blade holder 402, the dropping block 2013, and the collecting trough 2014 are all provided with matching dropping slopes. The sheared waste will be discharged from the shearing unit through the dropping slopes on the lower blade holder 402, the dropping block 2013, and the collecting trough 2014. In this embodiment, the first pad 2011 and the second pad 2012 respectively serve to install the material drop block 2013 and the lower support plate 404, and the first pad 2011 and the second pad 2012 can limit and guide the lower cutter holder 402 and the lower cutter head 403 between them.

[0052] like Figure 4 , 5 As shown in Figure 6, the vertical support plate 202 and the support rod 204 are respectively arranged on the front and rear sides of the shearing unit along the pushing direction of the steel grating 8. The support rod 204 is arranged on the front side of the shearing unit near the horizontal bar to be sheared, and the vertical support plate 202 is arranged on the rear side of the shearing unit near the horizontal bar after shearing and on the outer side. On the other side of the vertical support plate 202, there are two ribs 2021 and two reinforcing ribs 2022. The ribs 2021 are used to provide support for the top plate 203, and the reinforcing ribs 2022 are used to enhance the connection between the vertical support plate 202 and the top plate 203, thereby enhancing the strength and stability of the connection between the vertical support plate 202 and the top plate 203. A second notch 2023 for the steel grating 8 to pass through is provided in the middle of the vertical support plate 202. In this embodiment, the support rod 204 is used to install the top plate 203 and also facilitates the horizontal bar to enter the shearing unit through the inner side of the support rod 204 for shearing. The sheared horizontal bar can be removed from the shearing unit through the second notch 2023.

[0053] In this embodiment, when the shearing unit is used to shear the excess part of the crossbar, the upper power source 301 first drives the upper pressure block 302 and the upper cutter head 303 to press down the steel grating 8, and then the lower cutter head 402 and the lower cutter head 403 are driven by the lower power source 401 to shear the crossbar upward. Since the upper cutter head 303 and the upper pressure block 302 will cooperate with the lower support plate 404 to stabilize the steel grating 8, and the crossbar will also be pressed by the above three, the crossbar can maintain its shape and the stability of its connection with the flat steel under the impact of the lower cutter head 403.

[0054] like Figure 4 , 5As shown in Figure 6, the second moving unit 5 includes a lead screw 501, a second power source 502, a nut mounting base 503 mounted on the lead screw 501, two second slide rails 504 mounted on the frame 1, and multiple sliders 505 mounted on the second slide rails 504. The length direction of the lead screw 501 is perpendicular to the pushing direction of the steel grating 8. The shearing unit is connected to the nut mounting base 503 and the sliders 505. The second power source 502 is used to drive the nut mounting base 503, the shearing unit, and the sliders 505 to move along the axial direction of the lead screw 501. The shearing unit and the sliders 505 are connected to the nut mounting base 501. Driven by 503, the shearing unit moves along the second slide rail 504. In this embodiment, the second power source 502 is a motor. When processing steel gratings 8 of different widths, the motor can be turned on to adjust the lateral position of the shearing unit to adapt to the current processing requirements. After adjustment, the nut mounting seat 503 and the shearing unit can be locked in the current position, which facilitates the shearing unit to process steel gratings 8 of the same width within a certain period of time. In addition, the second slide rail 504 and the slider 505 guide the movement of the nut mounting seat 503 and the shearing unit, improving the accuracy of the shearing unit moving along the axial direction of the lead screw 501.

[0055] like Figure 6 As shown, a detection mounting plate is provided on the front side of the upper shearing part 3 near the crossbar to be sheared, and the sensor 6 is disposed on the detection mounting plate. In this embodiment, the sensor 6 is specifically a reflective photoelectric sensor 6. In other embodiments, the sensor 6 may also be an industrial camera or a laser rangefinder.

[0056] This invention also provides a method for side-shearing steel grating, applied to the aforementioned steel grating side-shearing machine and the aforementioned pushing device, comprising the following steps:

[0057] S1: The steel grating 8 is placed on the frame 1, and the lifting unit 7021 drives the clamping unit 702 to move down and clamp the steel grating 8.

[0058] S2: The lifting unit 7021 drives the clamping unit 702 and the steel grating 8 to move upward, and the first moving unit 701 moves toward the shearing assembly to push the steel grating 8. After the shearing crossbar is pushed to the shearing unit, the lifting unit 7021 drives the clamping unit 702 to move downward to press the steel grating 8.

[0059] S3: The second moving unit 5 adjusts the position of the two shearing units according to the width of the steel grating 8 to be processed, so that the two ends of the crossbar to be sheared enter the two shearing units respectively, and then the shearing units shear the crossbar.

[0060] Alternatively, the two ends of the crossbar to be cut are directly pushed into two cutting units, which cut the crossbar.

[0061] S4: After the above shearing is completed, the pushing component repeatedly pushes the steel grating 8 forward, so that the next batch of crossbars to be sheared is directly pushed into the two shearing units. The shearing units then repeatedly shear the crossbars to be sheared until the steel grating 8 completes the overall processing.

[0062] S5: After the steel grating 8 has been fully processed, the pushing component releases the steel grating 8 and moves away from the shearing component to push the next steel grating 8.

[0063] Specific work process

[0064] When the steel grating 8 is pushed, the drive motor 7013 drives the gear to rotate, causing the first mounting bracket 7011, the clamping unit 702, and the steel grating 8 clamped by the clamping unit 702 to move along the first slide rail 7012. After the steel grating 8 moves to the preset position, the first slot 7029 limits the flat steel in the X and Z directions, the second slot 7030 limits the crossbar in the Y and Z directions, multiple rollers 1025 limit the entire steel grating in the Z direction, and multiple sets of second blocks 1032 and third blocks 1033 limit the flat steel in the X direction. The above-mentioned limiting forms a clamping and fixing of the steel grating 8, replacing the existing clamps. Since the steel grating is relatively long, multiple sets of pressure rollers 6 and guide plates 7 provide limiting, resulting in a better clamping effect; in addition, in the steel After the grating 8 moves to the preset position, the end of the crossbar to be sheared is located in the shearing unit. The upper power source 301 first drives the upper pressure block 302 and the upper cutter head 303 to press down the steel grating 8. Then, the lower cutter holder 402 and the lower cutter head 403 are driven by the lower power source 401 to shear the crossbar. After shearing is completed, the upper pressure block 302, the upper cutter head 303, the lower cutter holder 402 and the lower cutter head 403 return to the position before shearing. The first moving unit 701 then repeatedly drives the steel grating 8 to move forward. The shearing unit repeats the above shearing operation to shear the crossbar until the steel grating 8 is fully processed.

[0065] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
