Description

Technical Field

[0001] This invention relates to the technical field of profile cutting, and in particular to an automated cutting device for feeding fixed-length steel structure profiles. Background Technology

[0002] Profiles are objects with specific geometric shapes made of iron or steel, or other materials with a certain strength and toughness, through processes such as rolling, extrusion, and casting. These materials have fixed external dimensions, a specific cross-sectional shape, and specific mechanical and physical properties. Profiles can be used alone or further processed into other manufactured products, and are commonly used in building structures and manufacturing installations. To meet different usage requirements, profiles usually need to be cut to specified dimensions.

[0003] In existing profile cutting processes, such as Chinese Patent No. CN204053107U, a square steel positioning and cutting device is disclosed. This device includes a flange, with a base plate fixed perpendicularly to one end face of the flange. The base plate is equipped with a positioning component and a movable cutting component. The positioning component, located on the side of the base plate, includes a movable positioning plate and a positioning pin. The movable positioning plate has a positioning groove that mates with the positioning pin. The movable cutting component includes a movable clamping plate and a cutting saw blade. The movable clamping plate is movably mounted on the base plate and can move relative to or away from the flange. The cutting saw blade is movably mounted on a side of the movable clamping plate parallel to its direction of movement. This square steel positioning and cutting device has a simple structure and is suitable for batch square steel cutting.

[0004] In the aforementioned prior art, one end of the square steel is placed against a vertical plate, and the square steel is fixed by moving a clamping plate. Then, a cutting saw blade is used to cut the square steel. In the aforementioned prior art, the clamping of the square steel is mostly done manually, which is inefficient and the clamping stability is difficult to guarantee. Displacement is prone to occur during the cutting process, and the steel needs to be manually removed after cutting. This is not suitable for assembly line production or multi-segment cutting, and the cutting efficiency is greatly reduced. At the same time, the steel chips and other impurities generated during cutting are not collected. Steel chips left on the base plate can easily cause a gap between the base plate and the lower surface of the square steel, resulting in the square steel not being in a horizontal state after clamping, causing uneven cuts. Based on this, there is still room for improvement in the existing profile cutting technology. Summary of the Invention

[0005] To enable integrated clamping and release of square steel bars, as well as pneumatic suction buffering and lowering of the cut steel bars, this application provides an automated fixed-length cutting device for steel structure profiles. The technical solution of this automated fixed-length cutting device for steel structure profiles is as follows:

[0006] An automated fixed-length cutting device for steel structure profiles includes a worktable, an automatic clamping module, a vacuum generating module, a lifting module, a cutting machine, and a pneumatic suction module. The automatic clamping module is installed on the worktable, clamping and positioning the steel profile and automatically releasing it after multi-segment cutting. A vacuum generating module is located at the rear of the worktable, connected to a pneumatic suction module. The pneumatic suction modules are symmetrically installed on the front and rear sides of the cutting machine, cleaning the generated steel chips and providing a buffer for the lowering of the cut steel profile. The cutting machine is mounted on a lifting module via a bracket, and the lifting module is mounted on the worktable. The lifting module moves the cutting machine up and down to complete the cutting operation.

[0007] The automatic clamping module includes clamping block one, clamping block two, a transmission mechanism, and a positioning and unlocking mechanism. Clamping block one and clamping block two are symmetrically slidably arranged on the worktable. Clamping block one and clamping block two work together to clamp and lock the steel. The transmission mechanism, which is in compression cooperation with clamping block one, is installed on the worktable. The positioning and unlocking mechanism is provided inside clamping block two. Clamping block two is temporarily locked to the worktable through the positioning and unlocking mechanism. After cutting is completed, the position between clamping block two and the worktable is unlocked by squeezing the positioning and unlocking mechanism.

[0008] The air suction module includes an air supply mechanism, a suction cup mechanism, a pushing mechanism, and a recovery mechanism. The air supply mechanism is mounted on a bracket, and a suction cup mechanism is installed at the lower end of the air supply mechanism. A pushing mechanism is sleeved on the outside of the air supply mechanism, and a recovery mechanism is set on the side of the pushing mechanism closest to the cutting machine. Before cutting, the air supply mechanism and the recovery mechanism are ventilated. At this time, under the action of air suction, the steel chips on the worktable are collected. As the steel is cut downwards, the pushing mechanism and the suction cup mechanism come into contact with the upper surface of the steel in turn. When the suction cup mechanism comes into contact with the upper surface of the steel, the air supply mechanism and the suction cup mechanism are ventilated in cooperation with the pushing mechanism and the recovery mechanism. At this time, the steel is suctioned. The air suction module controls the air suction of the suction cup mechanism and the recovery mechanism by controlling the change of the air suction trajectory, thereby achieving the purpose of steel chip recovery before cutting and air suction-type lowering of the steel after cutting.

[0009] Preferably, the workbench includes a base, a cover plate, a linkage mechanism, a feeding roller, a clamping assembly, and a guide plate. The base has a discharge hole, and a cover plate is installed on the discharge hole. A conveyor belt located below the discharge hole is installed on the base. After unlocking, the clamping block 2 slides backward. At this time, the cover plate is adjusted downward under the drive of the linkage mechanism to open the discharge hole. At the same time, the cut steel falls from the discharge hole into the conveyor belt in a buffered manner and is output. The base and the cover plate are connected by an elastic hinge. A linkage mechanism is connected between the clamping block 2 and the cover plate. A feeding roller is rotatably installed on the right end of the base. The clamping assembly located on the right side of the feeding roller is installed on the base. The feeding roller conveys the steel to the left until the left end face of the steel is tightly pressed against the left end of the transmission mechanism. To prevent the steel from retracting, the clamping assembly further clamps the steel. A guide plate located in front of the cover plate is installed at the lower end of the base.

[0010] Preferably, the linkage mechanism includes an L-shaped link and a movable rod. The upper end of the L-shaped link is fixedly mounted on the clamping block two. A sliding groove is provided on the base corresponding to the position of the linkage mechanism. The L-shaped link and the cover plate are connected by a movable rod through a pin. The L-shaped link slides back and forth in the sliding groove along with the clamping block two, thereby driving the movable rod to move and thus controlling the opening and closing of the cover plate.

[0011] Preferably, the vacuum generating module includes an air pump and an elastic hose. The air pump is installed on the rear side of the workbench, and the output end of the air pump is uniformly equipped with elastic hoses. The elastic hoses pass through the lifting module and are connected to the air supply mechanism.

[0012] Preferably, the transmission mechanism includes a limiting plate, a baffle, a baffle return spring, a connecting frame, a driving block, and a driven block.

A connecting frame is mounted on the front end of the baffle, and the connecting frame is slidably arranged inside the worktable. Driving blocks are evenly arranged on the connecting frame, and the inclined surface of the driving block contacts the lower inclined surface of the driven block. The worktable is evenly divided into... A sliding groove is provided, and a driven block is slidably arranged in the sliding groove. The upper inclined surface of the driven block is in a pressing fit with clamping block one. A built-in spring is connected between clamping block one and the worktable. The built-in spring plays a reset role. The steel is conveyed to the left by the feeding roller until the left end face of the steel is tightly pressed against the baffle (at this time the baffle is pressed to the leftmost side). Driven by the connecting frame, the clamping block one is pressed backward by the front and rear pressing of the driving block and the driven block. The clamping block one is clamped in the locked state with the locking clamping block two.

[0013] Preferably, the positioning and unlocking mechanism includes a transmission gear, a pressure block, a locking pin, a pin return spring, a return spring, a pressing block, and a mounting block. The clamping block has a cavity inside, and the transmission gear is mounted inside the cavity via a pin. A pressure block is positioned above and in front of the transmission gear. A rack positioned behind the pressure block meshes with the transmission gear. A locking pin is positioned below and to the left of the transmission gear. A rack positioned in front of the locking pin meshes with the transmission gear. The transmission gear causes the pressure block and the locking pin to move in opposite directions. When the pressure block moves downwards, the transmission gear... The locking pin moves upward, and when it moves downward, it causes the pressure block to move upward through the transmission gear. A locking groove corresponding to the position of the locking pin is provided on the worktable. When the locking pin is in the initial position, it engages with the locking groove, thereby temporarily locking the position of the clamping block two. A pressing block is provided above the pressure block and is installed on the side wall of the cutting machine. A groove is provided at the rear end of the clamping block two, and an installation block is provided in the groove. The installation block is fixedly installed on the worktable. A return spring is connected between the installation block and the clamping block two, and the return spring resets the clamping block two.

[0014] Preferably, the pressing block includes a pressing element, a mounting shell, and a pin. The mounting shell is installed on the side wall of the cutting machine. The pressing element is slidably disposed in the mounting shell. The pressing element and the mounting shell are locked in position by the lateral insertion of the pin. The pressing element has through holes evenly opened from top to bottom. After the pressing element is adjusted to different height positions, the height is locked by the pin, thereby adapting to steel of different specifications.

[0015] Preferably, the gas delivery mechanism includes a sleeve, a slide rod, a gas connector, a sleeve spring, a valve core, a connecting member, and a compression spring. The sleeve is mounted on a bracket, and the slide rod is slidably arranged inside the sleeve. The sleeve and the slide rod are connected by a sleeve spring, which serves to reset the valve. A gas connector is provided at the upper end of the sleeve and is connected to an elastic hose. A connecting member is installed on the lower side wall of the slide rod. A valve core is slidably arranged inside the connecting member. The valve core controls the flow of gas between the gas delivery mechanism and the recovery mechanism. A compression spring connects the valve core and the connecting member. A T-shaped connecting groove is provided inside the valve core. Through holes are provided at the upper and lower ends of the connecting member. The compression spring always pushes the valve core inward.

[0016] Preferably, the suction cup mechanism includes a suction cup, a second valve core, a valve return spring, and a push rod. The suction cup is installed at the lower end of the slide rod and acts as an adsorbent for the steel. The second valve core is slidably disposed inside the suction cup. The raising and lowering of the second valve core controls whether the suction cup is ventilated. The second valve core has a T-shaped venting groove inside. A push rod is disposed at the bottom of the second valve core. The suction cup and the second valve core are connected by the valve return spring. The valve return spring always pushes the second valve core downward. When the push rod is not compressed, the second valve core in its natural state controls the air closure of the suction cup.

[0017] Preferably, the pushing mechanism includes a pushing component and a pushing return spring. The pushing component is slidably mounted on the outside of the sleeve and plays a pressing role. The pushing component and the sleeve are connected by the pushing return spring, which plays a resetting role for the pushing component.

[0018] Preferably, the recycling mechanism includes a dust collection box, a filter screen, a cleaning window, and a top pressure component. The dust collection box is installed on the outside of the pusher component and serves to store waste. The inside of the dust collection box has a serpentine air passage cavity. A filter screen is installed on the left side of the air passage cavity, which blocks the waste and keeps it in the air passage cavity. The front side of the air passage cavity is connected to the cleaning window by a hinge. Opening the cleaning window allows the waste in the air passage cavity to be removed. The top pressure component, which communicates with the outside of the air passage cavity, is installed on the pusher component. The top pressure component in its initial position abuts against the valve core. When the top pressure component and the valve core are in a squeezing contact, the through hole and the T-shaped connecting groove are aligned for airflow.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. The present invention provides an automated cutting device for feeding steel structure profiles to a fixed length. This application adopts an integrated design concept of clamping, cutting and releasing to automatically cut steel without manual operation. The device also cleans up the generated waste steel chips in a timely manner to avoid affecting the subsequent cutting effect.

[0021] 2. The automatic clamping module is mainly used for clamping square steel. During clamping, the square steel is moved to the working position by pushing the feed roller to the left. Under the action of the extrusion force, the clamping block one moves backward and clamps and locks the steel with the clamping block two which is temporarily locked in position. After the steel is cut and falls, the baffle is not squeezed due to the fall of the steel and returns to the right under the action of the baffle return spring. The clamping block one moves forward and returns to the original position. The entire clamping process is automated, with strong clamping stability and no insufficient clamping force caused by manual clamping.

[0022] 3. The air suction module mainly controls the air suction of the suction cup mechanism and the recovery mechanism by controlling the change of the air suction trajectory. This ensures timely dust removal of steel chips and other impurities before cutting (the T-shaped connecting groove inside valve core one is aligned with the through hole on the connecting part for air passage) and air suction positioning of the square steel surface during cutting (the T-shaped ventilation groove in valve core two is connected with the slide rod for air passage). The air suction positioning design enhances the stability of the square steel during cutting and ensures that the square steel will not fall directly after cutting (the square steel is slowly lowered by the air suction and pushing mechanism).

[0032] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0033] This application discloses an automated cutting device for feeding fixed length steel structure profiles, which automatically clamps and releases the steel through a clamping mechanism and performs air suction buffering to lower the cut steel.

[0034] Reference Figure 1As shown in this embodiment, an automated steel structure profile feeding and fixed-length cutting device is disclosed, including a worktable 1, an automatic clamping module 2, a vacuum generating module 3, a lifting module 4, a cutting machine 5, and a suction module 6. The worktable 1 is equipped with the automatic clamping module 2, which clamps and positions the steel and automatically releases it after multi-segment cutting. The vacuum generating module 3 is located at the rear of the worktable 1, and the suction module 6 is connected to the vacuum generating module 3. The suction module 6 is symmetrically installed on the front and rear sides of the cutting machine 5. The suction module 6... The generated steel chips serve as a dust collector and cleaner, while also providing a buffer for the cut steel as it is lowered. The cutting machine 5 is mounted on the lifting module 4 via a bracket, and the lifting module 4 is mounted on the worktable 1. The lifting module 4 drives the cutting machine 5 to move up and down to complete the cutting work. After the steel is transported to the worktable 1, the vacuum generating module 3 drives the air suction module 6 to vacuum the surface of the steel and the steel chips generated during the previous cutting. Then, the steel is clamped and locked by the automatic clamping module 2, and the cutting machine 5 is lowered by the lifting module 4 to perform multi-segment cutting on the clamped steel.

[0035] Reference Figure 2 As shown, in order to position the steel and maintain its stability during the cutting process, this application provides an automatic clamping module 2. Specifically, the automatic clamping module 2 includes a clamping block 1 21, a clamping block 22, a transmission mechanism 23, and a positioning and unlocking mechanism 24. The clamping blocks 1 21 and 22 are symmetrically slidably arranged on the worktable 1. The clamping blocks 1 21 and 22 work together to clamp and lock the steel. The transmission mechanism 23, which is in a pressing fit with the clamping block 1 21, is installed on the worktable 1. The positioning and unlocking mechanism 24 is provided inside the clamping block 22. The clamping block 22 and the worktable 1 are temporarily locked together. The clamping block 22 is temporarily locked to the worktable 1 by the positioning and unlocking mechanism 24. After the cutting is completed, the clamping block 22 is unlocked from the worktable 1 by pressing the positioning and unlocking mechanism 24.

[0036] Reference Figure 2As shown, in order to clean dust and steel chips generated during the cutting process, this application provides an air suction module 6. Specifically, the air suction module 6 includes an air supply mechanism 61, a suction cup mechanism 62, a pushing mechanism 63, and a recovery mechanism 64. The air supply mechanism 61 is mounted on a bracket, and the suction cup mechanism 62 is installed at the lower end of the air supply mechanism 61. The pushing mechanism 63 is sleeved on the outside of the air supply mechanism 61, and the recovery mechanism 64 is located on the side of the pushing mechanism 63 closest to the cutting machine 5. Before cutting, the air supply mechanism 61 and the recovery mechanism 64 are ventilated, and at this time, the air suction effect... As the steel is cut downwards, the steel chips on the workbench 1 are collected. As the steel is cut downwards, the pushing mechanism 63 and the suction cup mechanism 62 come into contact with the upper surface of the steel. When the suction cup mechanism 62 comes into contact with the upper surface of the steel, the air supply mechanism 61 and the suction cup mechanism 62 are ventilated in cooperation with the pushing mechanism 63 and the recovery mechanism 64. At this time, the steel is suctioned by air. The air suction module 6 controls the air suction status of the suction cup mechanism 62 and the recovery mechanism 64 by controlling the change of the air suction trajectory, thereby achieving the purpose of collecting steel chips before cutting and lowering the steel by air suction after cutting.

[0037] During the actual cutting process, the steel is pushed onto the worktable 1 from right to left. After the pushed steel comes into contact with the transmission mechanism 23, both move synchronously to the left. When the compressed transmission mechanism 23 moves to the far left, clamping block 1 21 moves to the far right under the compression of the transmission mechanism 23, thus locking the position of the steel in conjunction with clamping block 22. During the locking process, the recovery mechanism 64 cleans the surface of the steel and the steel chips generated during the previous cutting. Then, the lifting module 4 drives the cutting machine 5 to descend. During the descent, the pushing mechanism 63 first contacts the steel and gradually compresses it as the lifting module 4 descends. When the pushing mechanism 63 is compressed to a certain extent, it shifts relative to the air supply mechanism 61. At this point, the air supply mechanism 61 and the recovery mechanism 64... The air passage between the two is disconnected, the recovery mechanism 64 stops working, the air passage between the air supply mechanism 61 and the suction mechanism 62 is opened, and the suction mechanism 62 starts working, thereby adsorbing the upper surface of the steel. After the cutting machine 5 completes the multi-segment cutting of the steel (at this time, the cutting machine 5 is lowered to the lowest position), the clamping block 22 is unlocked under the squeezing cooperation of the positioning unlocking mechanism 24 and moves it backward a short distance (at this time, the clamping block 1 21 and the clamping block 22 no longer form a clamping state). The steel is buffered and lowered under the action of the pushing mechanism 63 and the auxiliary air suction cooperation of the suction mechanism 62. This application adopts the design concept of automatic integrated clamping, cutting and releasing to cut the steel in multiple segments without manual operation. The generated waste steel chips are cleaned up in time to avoid affecting the subsequent cutting effect.

[0038] Reference Figure 1 , Figure 3As shown, the workbench 1 includes a base 11, a cover plate 12, a linkage mechanism 13, a feeding roller 14, a clamping assembly 15, and a guide plate 16. A material discharge hole is provided on the base 11, and a cover plate 12 is installed on the material discharge hole. A conveyor belt located below the material discharge hole is installed on the base 11. After unlocking, the clamping block 22 slides backward. At this time, driven by the linkage mechanism 13, the cover plate 12 adjusts downward to open the material discharge hole. Simultaneously, the cut steel falls from the material discharge hole onto the conveyor belt in a buffered manner and is then output. 1 and cover plate 12 are connected by an elastic hinge. Clamping block 22 is connected to cover plate 12 by a linkage mechanism 13. Feeding roller 14 is rotatably installed on the right end of base 11. Clamping assembly 15 located on the right side of feeding roller 14 is installed on base 11. The steel is conveyed to the left by feeding roller 14 until the left end face of the steel is tightly pressed against the left end of transmission mechanism 23. In order to prevent the steel from retracting, the steel is further clamped by clamping assembly 15. Guide plate 16 located on the front side of cover plate 12 is installed at the lower end of base 11.

[0039] Reference Figure 3 As shown, the cover plate 12 provides bottom support for the steel being clamped and cut. After the steel is cut, the cover plate 12 needs to be adjusted in angle. The linkage mechanism 13 provided in this application controls the opening and closing of the cover plate 12 to ensure that the cover plate 12 is appropriately adjusted for the current environment. Specifically, the linkage mechanism 13 includes an L-shaped link 131 and a movable rod 132. The upper end of the L-shaped link 131 is fixedly installed on the clamping block 22. A sliding groove is provided on the base 11 corresponding to the position of the linkage mechanism 13. The movable rod 132 is connected to the L-shaped link 131 and the cover plate 12 by a pin. The L-shaped link 131 slides back and forth in the sliding groove with the clamping block 22, thereby driving the movable rod 132 to move, and thus controlling the opening and closing of the cover plate 12.

[0040] During the actual cutting process, the feeding roller 14 conveys the steel to the left until the left end of the steel is tightly pressed against the left end of the transmission mechanism 23. Then, the clamping assembly 15 further clamps the steel to prevent it from retracting. After the cutting is completed, the clamping block 22 is unlocked from the base 11 through the positioning unlocking mechanism 24. The clamping block 22, which is squeezed, drives the L-shaped connecting rod 131 to move backward. The L-shaped connecting rod 131 adjusts the angle of the cover plate 12 downward through the movable rod 132, thereby opening the dropping hole. At this time, the suction cup mechanism 62 places the steel piece. Under the combined action of the opened cover plate 12 and the guide plate 16, the steel falls onto the conveyor belt.

[0041] Reference Figure 1 , Figure 3As shown, the vacuum generating module 3 includes an air pump 31 and an elastic hose 32. The air pump 31 is installed on the rear side of the workbench 1. The output end of the air pump 31 is evenly equipped with elastic hoses 32. The elastic hoses 32 pass through the lifting module 4 and are connected to the air supply mechanism 61.

[0042] During the actual cutting process, the air pump 31 is always in operation to ensure the normal operation of the entire air suction module 6.

[0043] Reference Figure 2 As shown, the transmission mechanism 23 includes a limiting plate 231, a baffle 232, a baffle return spring 233, a connecting frame 234, a driving block 235, and a driven block 236. The limiting plate 231 is mounted on the worktable 1. The baffle 232 is horizontally slidably arranged inside the limiting plate 231, and the limiting plate 231 provides left-side limitation for the movable baffle 232. The baffle 232 and the limiting plate 231 are connected by the baffle return spring 233, which provides a reset function. The connecting frame 234 is mounted on the front end of the baffle 232 and is slidably arranged inside the worktable 1. Driving blocks 235 are evenly arranged on the connecting frame 234. The inclined surface of 235 contacts the lower inclined surface of the driven block 236. Sliding grooves are evenly provided on the worktable 1. The driven block 236 is slidably arranged in the sliding groove. The upper inclined surface of the driven block 236 is in a pressing fit with the clamping block 21. An internal spring is connected between the clamping block 21 and the worktable 1. The internal spring plays a reset role. The steel is conveyed to the left by the feeding roller 14 until the left end face of the steel is tightly pressed against the baffle 232 (at this time, the baffle 232 is pressed to the leftmost side). Driven by the connecting frame 234, the clamping block 21 is pressed backward by the front and rear pressing of the driving block 235 and the driven block 236. The clamping block 22 in the locked state clamps the steel.

[0044] During the actual cutting process, the steel is fed to the left until the left end face of the steel is tightly pressed against the baffle 232. Then the two move to the left in sync. The synchronously moving connecting frame 234 drives the drive block 235 to squeeze the driven block 236 upward. The driven block 236 squeezes the clamping block 21 backward. When the baffle 232 moves to the leftmost side, the clamping block 21, which has moved to the last side, and the clamping block 22, which is temporarily locked in position, clamp and lock the steel. After the steel is cut in multiple segments, the cut steel falls and is output. At this time, the baffle 232 is not squeezed and resets to the right under the action of the baffle reset spring 233. The clamping block 21 moves forward and resets, waiting for the subsequent steel to be re-input.

[0045] Reference Figure 3 , Figure 4As shown, in order to quickly unlock the clamped steel after cutting, this application provides a positioning unlocking mechanism 24. Specifically, the positioning unlocking mechanism 24 includes a transmission gear 241, a pressure block 242, a locking pin 243, a pin return spring 244, a return spring 245, a pressing block 246, and a mounting block 247. The clamping block 22 has a cavity inside, and the transmission gear 241 is installed in the cavity through a pin shaft. The pressure block 242 is provided above the front side of the transmission gear 241. A rack 1 located behind the pressure block 242 meshes with the transmission gear 241. A locking pin 243 is provided below the left side of the transmission gear 241. A rack 22 located in front of the locking pin 243 meshes with the transmission gear 241. The transmission gear 241 causes the pressure block 242 and the locking pin 243 to move in opposite directions. When the pressure block 242 moves downward, the locking pin 243 moves upward through the action of the transmission gear 241. When the locking pin 243 moves downward, the pressure block 242 moves upward through the action of the transmission gear 241. A locking groove corresponding to the position of the locking pin 243 is provided on the worktable 1. The locking pin 243 engages with the locking groove in the initial position, thereby temporarily locking the position of the clamping block 22. A pressing block 246 is provided above the pressure block 242 and is installed on the side wall of the cutting machine 5. A groove is provided at the rear end of the clamping block 22, and an installation block 247 is provided in the groove. The installation block 247 is fixedly installed on the worktable 1. A return spring 245 is connected between the installation block 247 and the clamping block 22. The return spring 245 resets the clamping block 22.

[0046] During the actual unlocking process of clamping block 22, pressing block 246 descends synchronously with the descending cutting machine 5. After pressing block 246 contacts the pressure block 242, it descends synchronously. Through the action of transmission gear 241, locking pin 243 moves upward. After the cutting machine 5 completely cuts the steel, the upward-moving locking pin 243 completely disengages from the locking groove, clamping block 22 is unlocked. The cutting machine 5 continues to descend and feed a certain distance. The pressing block 246, which continues to descend, has its lower inclined surface touching the pressure block 242. Under the pressure between the inclined surfaces, clamping block 22 is forced to move backward, thus unlocking the cut steel. After the steel falls and is output, the cutting machine 5 drives the pressing block 246 to rise. Clamping block 22 is reset under the action of return spring 245. After clamping block 22 is reset, locking pin 243 moves downward under the action of pin reset spring 244 and re-engages with locking groove. At the same time, the downward movement of locking pin 243 will cause the pressure block 242 to move upward through the action of transmission gear 241, completing the reset.

[0047] Reference Figure 4As shown, in order to ensure that this application is applicable to the cutting of steel of different specifications (the height of steel of different specifications will also be different), this application is provided with a height-adjustable pressing block 246, thereby ensuring that the descent depth of the cutting machine 5 meets the current cutting requirements of the steel. Specifically, the pressing block 246 includes a pressing element, a mounting shell and a pin. The mounting shell is installed on the side wall of the cutting machine 5. The pressing element is slidably arranged in the mounting shell. The pressing element and the mounting shell are locked in position by the horizontal insertion of the pin. The pressing element has through holes evenly opened from top to bottom. The height adjustment of the pressing block 246 is specifically to slide the pressing element up and down to a suitable height, and then re-lock the position of the pressing element and the mounting shell by the horizontal insertion of the pin.

[0048] Reference Figure 5 , Figure 6 As shown, this application controls the dust collection process and the air suction positioning on the upper surface of steel by changing the trajectory of the gas channel. Specifically, the air supply mechanism 61 includes a sleeve 611, a slide rod 612, an air passage connector 613, a sleeve spring 614, a valve core 615, a connecting piece 616, and a compression spring 617. The sleeve 611 is mounted on a bracket, and the slide rod 612 is slidably arranged inside the sleeve 611. The sleeve 611 and the slide rod 612 are connected by the sleeve spring 614, which plays a reset role. An air passage connector is provided at the upper end of the sleeve 611. The head 613 and the air connector 613 are connected to the flexible hose 32. A connecting piece 616 is installed on the lower side wall of the slide rod 612. A valve core 615 is slidably installed inside the connecting piece 616. The valve core 615 controls whether the air passage between the air supply mechanism 61 and the recovery mechanism 64 is unobstructed. A compression spring 617 is connected between the valve core 615 and the connecting piece 616. A T-shaped connecting groove is opened inside the valve core 615. Through holes are opened at the upper and lower ends of the connecting piece 616. The compression spring 617 always maintains a tendency to push the valve core 615 inward.

[0049] Reference Figure 5 , Figure 6 , Figure 7 As shown, the suction cup mechanism 62 includes a suction cup 621, a second valve core 622, a valve return spring 623, and a push rod 624. The suction cup 621 is installed at the lower end of the slide rod 612. The suction cup 621 adsorbs the steel. The second valve core 622 is slidably arranged inside the suction cup 621. The raising and lowering of the second valve core 622 controls whether the suction cup 621 is ventilated. The second valve core 622 has a T-shaped venting groove inside. The push rod 624 is arranged at the bottom of the second valve core 622. The suction cup 621 and the second valve core 622 are connected by the valve return spring 623. The valve return spring 623 always pushes the second valve core 622 downward. When the push rod 624 is not squeezed, the second valve core 622 in its natural state controls the suction cup 621 to close the air.

[0050] Reference Figure 5 , Figure 6 As shown, the pushing mechanism 63 includes a pushing component 631 and a pushing return spring 632. The pushing component 631 is slidably mounted on the outside of the sleeve 611 and plays a pressing role. The pushing component 631 and the sleeve 611 are connected by the pushing return spring 632, which plays a resetting role for the pushing component 631.

[0051] Reference Figure 5 , Figure 6 , Figure 8 As shown, the recycling mechanism 64 includes a dust collection box 641, a filter screen 642, a cleaning window 643, and a top pressure member 644. The dust collection box 641 is installed on the outside of the pusher 631 and serves to store waste. The dust collection box 641 has a serpentine air passage cavity inside. The filter screen 642 is provided on the left side of the air passage cavity. The filter screen 642 serves to block the waste and keep the waste in the air passage cavity. The cleaning window 643 is connected to the front of the air passage cavity by a hinge. The waste in the air passage cavity can be collected and removed by periodically opening the cleaning window 643. The top pressure member 644, which communicates with the outside of the air passage cavity, is installed on the pusher 631. The top pressure member 644 is initially pressed against the valve core 615. When the top pressure member 644 and the valve core 615 are in a squeezing contact, the through hole and the T-shaped connecting groove are aligned for air passage.

[0052] During the actual cutting process, before cutting begins, the initial pressure member 644 presses against the valve core 615. The T-shaped connecting groove inside the valve core 615 aligns with the through hole on the connecting member 616 for air passage. At this time, the air passage between the air supply mechanism 61 and the recovery mechanism 64 is unobstructed. Under the suction of the air pump 31, steel chips, dust, and other impurities are sucked into the air passage cavity inside the dust collection box 641. At the same time, the impurities are retained in the air passage cavity by the filter screen 642. Then, the cutting machine 5 is driven to descend by the lifting module 4. During the descent, the lower end of the pusher 631 contacts the steel. Under the reaction force, the pusher 631 moves upward relative to the slide rod 612. The pressure member 644, which rises synchronously, is misaligned with the valve core 615. The valve core 615 is compressed by the spring 617. The lower valve core 615 extends partially from the connecting member 616. The T-shaped connecting groove inside the valve core 615 is misaligned with the through hole on the connecting member 616. At this time, the air passage between the air supply mechanism 61 and the recovery mechanism 64 is closed, and the recovery mechanism 64 stops working. Correspondingly, the T-shaped venting groove in the raised valve core 622 is vented through the slide rod 612, which opens the air passage between the air supply mechanism 61 and the suction cup mechanism 62. After the lower end of the suction cup 621 contacts the upper surface of the steel, the suction cup 621 is evacuated under the action of the air pump 31, thereby sucking and positioning the steel. This application controls the gas delivery trajectory by cooperating with the air supply mechanism 61, the suction cup mechanism 62, the pushing mechanism 63, and the recovery mechanism 64, thus ensuring the dust removal treatment of steel chips and the air suction positioning of the upper surface of the steel.

[0053] The implementation principle of this embodiment is as follows:

[0054] (1): Place the steel on the workbench 1 and feed it to the left by the feeding roller 14;

[0055] (2): The steel conveyed to the left contacts the baffle 232 and moves synchronously until it reaches the leftmost side. At this time, under the pressure of the drive block 235 and the driven block 236, the clamping block 1 21 is squeezed to the last side. The steel is clamped and locked by the rearward-moving clamping block 1 21 and clamping block 2 22. The recycling mechanism 64 performs dust removal on the steel chips generated by the previous cutting and the impurities on the surface of the steel.

[0056] (3): Cutting, the cutting machine 5 is driven down by the lifting module 4 to cut the steel in multiple segments. During the descent of the cutting machine 5, the air passage of the recovery mechanism 64 is gradually closed, and the air passage between the air supply mechanism 61 and the suction cup mechanism 62 is opened. Under the action of air suction, the suction cup 621 adsorbs the upper surface of the steel.

[0057] (4): After the cutting machine 5 completes the multi-segment cutting of the steel, the clamping block 22 is unlocked under the squeezing cooperation of the positioning unlocking mechanism 24 and moves backward a short distance. The steel is buffered and lowered to the conveyor belt for output under the action of gravity and the auxiliary air suction cooperation of the suction cup mechanism 62.

[0058] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
