Description

Technical Field

[0001] This invention relates to the field of keel cutting technology, and in particular to a light steel villa keel cutting machine mechanism. Background Technology

[0002] The keel of a light steel villa is the core framework of a light steel structure house. It is made of high-strength aluminum-zinc coated steel strip as raw material, and is cold-bent and rolled into standardized profiles such as C-shaped and U-shaped. It is assembled into an overall frame system by bolts and self-tapping screws. It mainly bears the load support of walls, floors and roofs. It is the core component that ensures the stability, earthquake resistance and wind resistance of the house. It is the basic core material for the green and efficient construction of light steel villas. Mechanical cutting of keel frames, distinct from traditional manual cutting, is crucial for improving the quality and efficiency of light steel villa construction. During the design and production of light steel villas, the manufactured keel components are cut to the required lengths, enabling standardized mass production, significantly shortening the processing cycle, reducing on-site work, and effectively lowering labor costs and construction errors. Currently, in mechanical cutting operations, the light steel keel to be cut is measured and placed horizontally, then cut using a flat cutting blade. During cutting, due to the keel's structural characteristics, the blade contact with it causes burrs and curling at the cut, which can lead to excessive deformation and affect the keel's normal use. Currently, burrs and curling at the cut are mainly addressed manually through subsequent grinding. However, due to limited operating space on the inner side of the keel, the grinding effect is poor when there are severe curling and burrs, easily leading to false tightening during keel assembly, posing safety hazards in connection stress, and is time-consuming, labor-intensive, and ineffective.

[0003] Therefore, how to provide a cutting mechanism for light steel villa keel is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] One objective of this invention is to provide a light steel villa keel cutting mechanism. This invention can solve the problems of poor burr treatment and inner and outer edge curling at the cut ends of the keel, as well as the keel deformation caused by cutting and post-processing.

[0005] According to an embodiment of the present invention, a light steel villa keel cutting mechanism includes a cutting support, on which a processing component is movably mounted. The processing component includes a working slide, a flat cutting blade, and two grinding discs. The two grinding discs are rotatably mounted on one side of the working slide, and the flat cutting blade is vertically mounted on the side of the working slide away from the grinding discs. The working slide is horizontally movable within the cutting support, so that the flat cutting blade and the grinding discs sequentially come into contact with the light steel keel during processing. The cutting support is provided with support components on both sides. Each support component includes a keel support, a pull slide, a custom mold base, and a clamping enclosure. The pull slide is movably located on one side of the keel support. The light steel keel is inserted through the custom mold base. The clamping enclosure is installed on the pull slide and fixes the light steel keel together so that the light steel keel moves together when the pull slide moves. The movement of the pull slide is controlled when the working slide moves. A curling and combing component is provided on one side of the pull slide. The curling and combing component includes a combing template.

[0006] Preferably, a drive screw is horizontally inserted into the cutting support via a bearing, and a working slide is horizontally movable within the cutting support. Two screw sleeves are provided at the lower end of the working slide, and the working slide is connected to the drive screw via the two screw sleeves. A grinding support is vertically provided on one side of the upper end of the working slide, and a blowing groove is provided inside the grinding support. A synchronous shaft is rotatably inserted into the center of the blowing groove, and both ends of the synchronous shaft pass through the grinding support and are fixedly connected to the center of the two grinding discs.

[0007] Preferably, the synchronous shaft is fitted with a blowing impeller at the position inside the blowing groove, and an air inlet pipe and a connecting air outlet pipe are respectively connected to both sides of the blowing groove.

[0008] Preferably, the keel support has two horizontal slide rails located near the cutting support. The lower end of the pull slide is movably connected to the two horizontal slide rails via a sliding sleeve. The custom mold base is vertically located at the upper end of the pull slide near the cutting support. Both the custom mold base and the combing template have through slots. The light steel keel is movably inserted into the through slots.

[0009] Preferably, the working slide has two pull grooves, and the lower end of each of the two pull slides is provided with a pull rod. The two pull rods are vertically and movably inserted into the two pull grooves respectively. A cutting gap is provided between the two custom mold seats. During the cutting process, the cutting gap is equal to the thickness of the flat cutter.

[0010] Preferably, the clamping enclosure is fitted onto the light steel keel, and a three-headed clamping box is vertically installed inside the clamping enclosure. The three-headed clamping box is inserted into the inner side of the light steel keel. A clamping air chamber is opened in the three-headed clamping box, and piston sleeves are provided on three sides of the three-headed clamping box that are connected to the clamping air chambers. A clamping piston rod is movably inserted into each piston sleeve. One end of each clamping piston rod passes through the piston sleeve and is provided with a clamping block. A first spring is provided at the position of the clamping piston rod inside the piston sleeve. When high-pressure gas is filled into the clamping air chamber, the three clamping blocks abut against the side of the light steel keel and abut against the inner side wall of the clamping enclosure, thereby realizing three-point clamping of the light steel keel and the clamping enclosure.

[0011] Preferably, the keel support is provided with a horizontal adapter end above it, and an adapter air groove is provided inside the adapter end. The adapter air grooves of the two adapter ends are respectively connected to the adapter air outlet pipe and are provided with adapter hoses. One side of the adapter air groove is connected to the clamping air chamber of the three-head clamping box and is provided with a connecting hose. One side of the clamping air chamber of the three-head clamping box is connected to a one-way air outlet and is provided with a one-way valve inside the one-way air outlet.

[0012] Preferably, a switching piston groove is provided on the side of the adapter end near the custom mold base, which is connected to the adapter air groove. A U-shaped diversion groove is provided on one side of the custom mold base. A piston tube is provided on the position of the custom mold base near the adapter end, which is connected to the U-shaped diversion groove. One side of the piston tube is movably inserted into the switching piston groove and a piston is provided therein. Several side ventilation grooves are provided on the side of the switching piston groove away from the adapter air groove. Several adapter air holes are provided on the position of the piston tube in the switching piston groove, and several exhaust keyways are provided on the side wall of the piston tube outside the switching piston groove.

[0013] Preferably, the customized mold base has a connected U-shaped diversion groove and several telescopic piston grooves. Several telescopic piston rods are horizontally provided on one side of the combing template. One side of each telescopic piston rod is movably inserted into a telescopic piston groove. Several second springs are provided on the side of the telescopic piston rod located in the telescopic piston groove and away from the U-shaped diversion groove.

[0014] Preferably, the pull slide groove includes, in sequence along the moving direction, a cutting straight groove, a pushing inclined groove, a grinding moving groove, and a grinding inclined groove. When the working slide moves horizontally within the cutting support, when the pull slide rod reaches the pushing inclined groove, it pushes the two pull slides together with the light steel keel away from the cutting support, facilitating the movement of the two grinding discs between the two cut light steel keels. When the pull slide rod reaches the grinding inclined groove, it pulls the two pull slides together with the light steel keel to contact the grinding discs, so that the two grinding discs grind the ends of the two light steel keels.

[0015] The beneficial effects of this invention are: This mechanism relies on the working slide to drive the flat cutting blade to complete the keel cutting. With the help of the pull slide and the pull slide rod, it automatically controls the separation and convergence of the light steel keels on both sides, allowing the grinding disc to enter between the ends of the two keels to complete the end face grinding. There is no need for manual transfer and grinding. At the same time, the airflow drives the impeller to rotate the grinding disc, and the same air source enables the three-point clamping box to fix the keel at three points, ensuring that the keel is firmly positioned during the cutting and grinding process and avoiding processing displacement. During processing, the combing template extends to pre-comb and shape the keel cut edges and burrs, turning the burrs towards the grinding position for efficient removal by the grinding disc. In conjunction with the movement of the light steel keel, the combing template automatically retracts to prevent interference with the grinding disc. The entire process can complete cutting, edge combing, and end face grinding, improving cut quality, reducing keel deformation, reducing manual workload, and improving the processing efficiency and finished product quality of light steel keel.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0026] like Figures 1 to 9 As shown, an embodiment of the present invention provides a cutting mechanism for a light steel villa keel machine, including a cutting support 1. A processing component is movably mounted on the cutting support 1. The processing component includes a working slide 3, a flat cutting blade 5, and two grinding discs 9. The two grinding discs 9 are rotatably mounted on one side of the working slide 3, and the flat cutting blade 5 is vertically mounted on the side of the working slide 3 away from the grinding discs 9. A drive screw 4 is horizontally inserted and connected to the cutting support 1 through a bearing. The working slide 3 is horizontally movably mounted in the cutting support 1. Two screw sleeves are provided at the lower end of the working slide 3. The working slide 3 is connected to the drive screw 4 through the two screw sleeves, so that the flat cutting blade 5 and the grinding discs 9 sequentially make contact with the light steel keel 16 for processing. The drive screw 4 is driven and controlled by a drive motor controlled by a PLC servo, so as to realize the reciprocating movement control of the working slide 3 in the cutting support 1. A support plate is provided below the working slide 3 in the cutting support 1 to keep the working slide 3 stable when it slides horizontally in the cutting support 1.

[0027] A grinding support 6 is vertically mounted on one side of the upper end of the working slide 3. A blowing groove 7 is formed inside the grinding support 6. A synchronous shaft is rotatably inserted into the center of the blowing groove 7. Both ends of the synchronous shaft pass through the grinding support 6 and are fixedly connected to the centers of two grinding discs 9. A blowing impeller 8 is fitted onto the synchronous shaft within the blowing groove 7. An air inlet pipe 11 and an air outlet pipe 10 are respectively connected to both sides of the blowing groove 7. The grinding support 6 and the flat cutting blade 5 are respectively located on both sides of the working slide 3. When the flat cutting blade 5 is operating, the grinding support 6 is moved away from the working slide 3. In the working area, when the grinding support 6 is in the working area, the flat cutter 5 is away from the working area. The grinding disc 9 is vertically rotated on both sides of the grinding support 6 via a synchronous shaft, corresponding to the ends of the two light steel keels 16 after being cut by the flat cutter 5. The air inlet pipe 11 is connected to the existing air compressor equipment to send high-pressure airflow into the blowing groove 7. After entering the blowing groove 7, the high-pressure airflow is blown out from the position of the transfer outlet pipe 10. During the airflow process, the blowing impeller 8 rotates in the blowing groove 7, thereby realizing the high-speed rotation of the two grinding discs 9 via the synchronous shaft.

[0028] Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 9 The cutting support 1 has support components on both sides. Each support component includes a keel support 2, a pull slide 13, a custom mold base 14, and a clamping enclosure 17. The pull slide 13 is movably mounted on one side of the keel support 2. Two horizontal slide rails 12 are horizontally mounted inside the keel support 2 near the cutting support 1. The lower end of the pull slide 13 is movably connected to the two horizontal slide rails 12 through a sliding sleeve. The custom mold base 14 is vertically mounted on the upper end of the pull slide 13 near the cutting support 1. The custom mold base 14 and the combing template 26 are both provided with through slots 15. The light steel keel 16 is movably inserted into the through slots 15. The function of the custom mold base 14 is to provide lateral support for the cutting position of the light steel keel 16 and guide and constrain the movement of the flat cutter 5, so that the flat cutter 5 can stably cut the light steel keel 16.

[0029] Please refer to Figure 1 , Figure 4 and Figure 5The working slide 3 has two pull grooves 35. Each of the two pull slides 13 has a vertically extending pull rod 34 at its lower end. The two pull rods 34 are vertically inserted into the two pull grooves 35. A cutting gap is provided between the two custom mold bases 14. During cutting, the cutting gap is equal to the thickness of the flat cutter 5. The pull grooves 35, along the direction of movement, sequentially include a cutting straight groove, a pushing inclined groove, a grinding moving groove, and a grinding inclined groove. When the working slide 3 moves horizontally within the cutting support 1, when the pull rods 34 reach the pushing inclined groove, they push the two pull slides 13 together with the light steel keel 16 away from the cutting support 1. This facilitates the movement of the two grinding discs 9 between the two cut light steel keels 16. When the sliding rod 34 reaches the grinding groove, the two pulling slides 13, together with the light steel keels 16, are pulled to contact the grinding discs 9, so that the two grinding discs 9 grind the ends of the two light steel keels 16. Through the reciprocating movement of the working slide 3, the two light steel keels 16 are separated along with the pulling slide 13. When the grinding discs 9 are between the two light steel keels 16, the two pulling slides 13, under the action of the pulling slide rod 34 in the grinding groove, pull the ends of the two light steel keels 16 closer to the grinding discs 9, completing the grinding operation.

[0030] In this embodiment, when the light steel keel 16 horizontally passes through the through slots 15 of the two customized mold bases 14, the two customized mold bases 14 provide horizontal support for the light steel keel 16. At this time, the working slide 3 moves horizontally through the drive screw 4, causing the flat cutter 5 to cut the light steel keel 16. After cutting, the drive screw 4 controls the working slide 3 to move in the opposite direction. When the working slide 3 moves from the push-off groove to the position of the pull slide rod 34, the pull slide rod 34 pushes the two pull slides 13 away from each other, thereby just... The ends of the slit light steel keel 16 are far apart. When the sliding rod 34 is moved to the grinding moving groove, the two pulling slides 13 are far apart to the farthest end. As the working slide 3 continues to move, the grinding disc 9 moves between the two customized mold seats 14. At this time, the working slide 3 continues to move. When the sliding rod 34 moves to the grinding inclined groove, it pulls the two pulling slides 13 to move towards the positions of the two grinding discs 9. As they move, the ends of the light steel keel 16 come into contact with the grinding discs 9 for grinding, thereby adjusting the grinding depth.

[0031] Please refer to Figure 6 and Figure 9The clamping frame 17 is mounted on the pull slide 13 and fixes the light steel keel 16 together, so that the light steel keel 16 moves together when the pull slide 13 moves. When the working slide 3 moves, the movement of the pull slide 13 is controlled. One side of the pull slide 13 is provided with a curling and combing component, which includes a combing template 26. The clamping frame 17 is sleeved on the light steel keel 16. A three-head clamping box 18 is vertically provided inside the clamping frame 17. The three-head clamping box 18 is inserted into the inner side of the light steel keel 16. A clamping air chamber is opened in the three-head clamping box 18. Piston sleeves 19 are provided on three sides of the three-head clamping box 18, which are connected to the clamping air chambers. Each clamping piston rod 20 is movably connected and inserted. One end of each clamping piston rod 20 passes through the piston sleeve 19 and is provided with a clamping block 21. A first spring is provided at the position of the clamping piston rod 20 inside the piston sleeve 19. When high-pressure gas is filled into the clamping air chamber, the three clamping blocks 21 respectively abut against the side of the light steel keel 16 and abut against the inner side wall of the clamping enclosure 17, realizing the three-point clamping of the light steel keel 16 and the clamping enclosure 17. When the high-pressure gas is blown out from the adapter outlet pipe 10, it will be sent into the two clamping air chambers through the adapter hose 36, and then push the three clamping blocks 21 to extend and move, so that the side of the light steel keel 16 abuts against the clamping enclosure 17 for clamping.

[0032] A horizontal adapter end 22 is provided above the keel support 2. An adapter air groove 23 is formed inside the adapter end 22. The adapter air grooves 23 of the two adapter ends 22 are respectively connected to adapter air outlet pipes 10 via adapter hoses 36. One side of the adapter air groove 23 is connected to the clamping air chamber of the three-head clamping box 18 via a connecting hose 24. One side of the clamping air chamber of the three-head clamping box 18 is connected to a one-way air outlet 37, and the one-way air outlet 37 is equipped with a one-way valve. The high-pressure gas delivered by the adapter hose 36 first... The air enters the adapter slot 23 of the adapter end 22, and then enters the clamping air chamber through the connecting hose 24. After that, the first spring is squeezed by the push clamping piston rod 20, and the clamping block 21 extends to clamp the light steel keel 16. When the clamping block 21 cooperates with the clamping enclosure frame 17 to clamp the light steel keel 16, the sliding block 13 is pulled to move horizontally through the sliding groove 35, so that the light steel keel 16 can move synchronously and will not remain in the same position when the sliding block 13 is pulled to move.

[0033] Please refer to Figure 6 and Figure 7The adapter end 22 has a switching piston groove 30 connected to the adapter air groove 23 on one side near the custom mold base 14. The custom mold base 14 has a U-shaped diversion groove 25 on one side. The custom mold base 14 has a piston tube 29 connected to the U-shaped diversion groove 25 near the adapter end 22. One side of the piston tube 29 is movably inserted into the switching piston groove 30 and has a piston. The switching piston groove 30 has several side ventilation grooves 31 on the side away from the adapter air groove 23. The piston tube 29 has several adapter air holes 32 connected to the position of the piston tube 29 in the switching piston groove 30. The piston tube 29 has several exhaust keyways 33 on the side wall outside the switching piston groove 30. The gas entering the adapter air groove 23 will enter the piston tube 29 through the side ventilation grooves 31 and then the adapter air holes 32, and then enter the U-shaped diversion groove 25.

[0034] Please refer to Figure 7 and Figure 8 The customized mold base 14 has a U-shaped diversion groove 25 with several telescopic piston grooves 28. Several telescopic piston rods 27 are horizontally arranged on one side of the combing template 26. One side of each telescopic piston rod 27 is movably inserted into one of the telescopic piston grooves 28. Several second springs are arranged on the side of the telescopic piston rod 27 located in the telescopic piston groove 28 and away from the U-shaped diversion groove 25. The high-pressure gas entering the U-shaped diversion groove 25 can simultaneously enter multiple telescopic piston grooves 28, and then simultaneously push the multiple telescopic piston rods 27 arranged on the combing template 26, so that the telescopic piston rods 27 squeeze the second springs and move, scraping and combing the inner and outer edges or burrs of the end of the light steel keel 16, so that the burrs or edges face the working area, which is convenient for the subsequent grinding disc 9 to grind and remove them, and shaping the end of the light steel keel 16 to avoid excessive deformation.

[0035] In this embodiment, when the high-pressure gas blows the grinding disc 9 to rotate at high speed, the high-pressure gas enters the transfer air groove 23. Simultaneously, the combing template 26 extends to scrape the end of the light steel keel 16, and the clamping block 21, in conjunction with the clamping frame 17, clamps the light steel keel 16. Before the grinding activity of the working slide 3, the end edge curling or burr pretreatment of the light steel keel 16 is completed, along with the high-speed rotation of the grinding disc 9 and the synchronous and stable movement of the sliding block 13 and the light steel keel 16. The high-pressure gas then enters the clamping air chamber. When the pressurized gas is continuously pressurized to break through the release pressure of the one-way valve, the high-pressure gas is ejected from the one-way outlet 37, realizing the airflow of the rotating grinding disc 9. After the combing template 26 combs the burrs and curls at the end of the light steel keel 16, since the adapter end 22 is fixedly connected to the keel support 2, when the slide block 13 and the customized mold base 14 are pulled to move horizontally, the adapter end 22 remains in position. The customized mold base 14 drives the piston tube 29 to slide and insert in the switching piston groove 30. The piston of the piston tube 29 moves further and further. The side vent groove 31 blocks the switching piston groove 30, preventing gas in the transfer air groove 23 from entering the U-shaped diversion groove 25. Instead, gas in the U-shaped diversion groove 25 enters the switching piston groove 30 through the transfer air hole 32 and exits through the exhaust keyway 33. Under the reset action of the second spring, the combing template 26 exposes the end of the light steel keel 16. When the grinding disc 9 is positioned between the two light steel keels 16, the light steel keel 16 facilitates rapid combing of burrs and curled edges facing the grinding disc 9. With rapid and precise grinding, when the piston of the piston tube 29 is far away from the side vent groove 31, the depth to which the piston of the piston tube 29 is inserted into the switching piston groove 30 is greater than the wear length of the end of the light steel keel 16. When the slide block 13, together with the customized mold base 14 and the light steel keel 16, is pulled to move closer to the grinding disc 9, the high-pressure gas in the transfer air groove 23 will not enter the U-shaped diversion groove 25, thus avoiding contact between the combing template 26 and the grinding disc 9, and improving the efficiency and quality of the processing of the rolled burrs on the inner side of the light steel keel 16.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
