Description

Technical Field

[0001] This invention belongs to the field of continuous processing technology of angle steel, specifically a continuous processing device for angle steel. Background Technology

[0002] Angle steel, as a key profile in construction and machinery manufacturing, often needs to be cut to the same length during processing to meet specific size requirements. After the cutting operation is completed, the cut surface must be finely ground at the same time. This process is crucial because hot cutting or mechanical cutting will form burrs, oxide layers and uneven slag on the cross-section, which not only affects the appearance quality of the component, but may also become stress concentration points and reduce the structural load-bearing capacity.

[0003] Patent CN222493042U discloses an angle steel cutting device, including a base plate, support legs, a first telescopic component, a drive mechanism, a cutting and grinding mechanism, a vertical plate, a second telescopic component, an angle steel placement platform, a third telescopic component, and a clamping plate. This design features a reasonable structure, convenient and efficient operation, and innovatively integrates cutting and grinding functions. After cutting the angle steel, the cut surface can be simultaneously ground immediately, completely changing the cumbersome process of using two separate devices in traditional processing methods. This integrated design not only significantly improves processing efficiency and shortens the production cycle but also effectively reduces the workload of operators, lowers equipment investment costs and space requirements for enterprises, fully embodying the efficient and compact design concept of modern processing equipment, and comprehensively meeting the diverse needs of angle steel processing.

[0004] In the above-mentioned solution, when cutting and grinding angle steel, the device can only cut one angle steel into two sections at a time. If one angle steel is to be cut into multiple sections, it is necessary to install and adjust the position of the angle steel multiple times, which wastes a lot of time and reduces the processing efficiency of angle steel. Secondly, after the angle steel is cut, only one section of angle steel is located in the slot, so only the cut surface of that section of angle steel can be ground, and the cut surface of the other section of angle steel cannot be ground. Therefore, the present invention provides a continuous angle steel processing device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A continuous angle steel processing device of this invention includes a frame, two sets of drive shafts rotatably mounted inside the frame, each drive shaft having a conveying mechanism at both ends, and several sets of conveying frames arranged around the two sets of conveying mechanisms. Four sets of workpiece placement racks are installed at equal intervals on the conveying frames. A cutting mechanism and a grinding mechanism are sequentially arranged on the frame. A material placement box is located at the bottom of the frame. Guide rings are installed on the two sets of drive shafts, and the guide rings are rotatably connected to the drive shafts. The material placement rack includes a receiving block mounted on the conveying frame, two sets of clamping plates symmetrically and movably mounted on the receiving block, and rubber blocks fixedly mounted on the clamping plates. A support block is set between two sets of rubber blocks. The support block is fixedly installed on the receiving block. A movable frame is movably installed inside the support block. A spring is set on the movable frame. A pressure rod is fixedly connected to the lower end of the movable frame. Two sets of inclined grooves are symmetrically opened on both sides of the movable frame. A pin is set at the lower end of the clamping plate. The end of the pin is located in the inclined groove. The end of the pressure rod is slidably connected to the outer ring of the guide ring. The outer ring of the guide ring is composed of a first annular surface, an inclined surface, and a second annular surface. Two sets of mounting grooves are symmetrically opened on the receiving block. Two sets of guide posts are symmetrically installed in the mounting grooves. The clamping plate is slidably connected to the two sets of guide posts. Slide grooves are opened on both sides of the movable frame. The slide grooves are slidably connected to the slide rails. The slide rails are fixedly installed inside the receiving block. In the above scheme, the entire process of feeding, clamping, cutting, grinding, and unloading is completed automatically without manual intervention, which improves the automation rate of the device. Secondly, the use of a sprocket and chain conveyor mechanism, driven by a motor, enables the circumferential motion of the conveyor frame, which can realize continuous processing of the workpiece and improve the processing efficiency of the workpiece. Furthermore, when the grinding disc passes through the workpiece, the grinding disc can grind two sets of cutting surfaces at the same time, which greatly improves the grinding efficiency of the workpiece.

[0007] Preferably, two sets of limiting plates are symmetrically installed on the frame, and the two sets of limiting plates are used to position the workpiece; When the workpiece is placed on the four sets of feeding racks, the workpiece is located between two sets of limiting plates. When the feeding rack moves the workpiece in a circular motion, the workpiece will move along the two sets of limiting plates until it is fixed on the feeding rack. Then the workpiece will be removed from the two sets of limiting plates to prevent the workpiece from shifting before it is fixed.

[0008] Preferably, the conveyor frame includes two sets of fixed blocks, which are respectively fixedly connected to two sets of conveying mechanisms. Four sets of crossbars are fixedly installed between the two sets of fixed blocks. An L-shaped block is fixedly connected to one set of fixed blocks. The end of the scissor-type telescopic frame is connected to the L-shaped block. Four nodes on the scissor-type telescopic frame are respectively connected to four sets of receiving blocks. Four sets of through holes are provided on the receiving blocks, and these through holes are slidably connected to the four sets of crossbars. A receiving rod is installed on one set of receiving blocks. A guide groove is provided on the guide ring, and the lower end of the receiving rod is located within the guide groove. The guide groove consists of a first annular groove, two sets of inclined grooves, and a second annular groove. The grinding mechanism includes a fixed frame, with both ends of the fixed frame fixedly mounted on the machine frame, a rotating rod rotatably mounted inside the fixed frame, three sets of reciprocating lead screws rotatably mounted at equal intervals on the fixed frame, two sets of movable plates symmetrically arranged on the reciprocating lead screws, and a grinding disc rotatably mounted at the lower end of the movable plate. The grinding disc is fitted onto the rotating rod. The fixed frame has three sets of rectangular slots equidistantly spaced, with slide rods fixedly installed in the rectangular slots. The slide rods slidably connect the two sets of movable plates. The rotating rod has three sets of rectangular strips arranged at equal angles. The inner ring of the grinding disc has three sets of guide slots arranged at equal angles. The guide slots slidably connect the rectangular strips. Rotating the reciprocating screw causes two sets of movable plates to move in opposite directions along the slide rod. These movable plates then drive two sets of grinding discs to move in opposite directions along the rotating rod, adjusting the distance between the grinding discs and the cutting surface. This maintains a good grinding effect on the cutting surface. Because the distance between the grinding discs and the cutting surface is adjustable, it not only avoids frequent replacement of the grinding discs but also extends their service life.

[0009] The beneficial effects of this invention are as follows: 1. The above solution automatically completes the entire process of feeding, clamping, cutting, grinding, and unloading without manual intervention, thus improving the automation rate of the device. Secondly, the use of a sprocket and chain conveyor mechanism, driven by a motor, enables the conveyor frame to move in a circular motion, which can realize continuous processing of workpieces and improve the processing efficiency of workpieces. Furthermore, when the grinding disc passes through the workpiece, the grinding disc can grind two sets of cutting surfaces at the same time, which greatly improves the grinding efficiency of the workpiece.

[0010] 2. When the workpiece is placed on the four sets of feeding racks, the workpiece is located between the two sets of limiting plates. When the feeding rack drives the workpiece to make a circular motion, the workpiece will move along the two sets of limiting plates until the workpiece is fixed on the feeding rack. Then the workpiece will be removed from the two sets of limiting plates to prevent the workpiece from shifting before it is fixed.

[0011] 3. When the grinding surface of the grinding disc becomes worn, the spacing between the cut angle steel increases. Rotating the reciprocating screw causes the two sets of movable plates to move in opposite directions along the slide rod. The two sets of movable plates drive the two sets of grinding discs to move in opposite directions along the rotating rod, adjusting the distance between the grinding discs and the cutting surface. This maintains a good grinding effect on the cutting surface. Since the distance between the grinding discs and the cutting surface can be adjusted, it not only avoids frequent replacement of the grinding discs but also increases the service life of the grinding discs.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] Example 1: As Figures 1 to 4 As shown in the embodiment of the present invention, a continuous angle steel processing device includes a frame 1. Two sets of drive shafts 2 are rotatably mounted inside the frame 1. Each end of the drive shaft 2 is provided with a conveying mechanism 3. Several sets of conveying frames 4 are arranged around the two sets of conveying mechanisms 3. Four sets of feeding racks 5 for placing workpieces 10 are installed at equal intervals on the conveying frames 4. A cutting mechanism 6 and a grinding mechanism 7 are arranged sequentially on the frame 1. A feeding box 8 is provided at the bottom of the frame 1. Guide rings 9 are installed on the two sets of drive shafts 2 and are rotatably connected to the drive shafts 2. The feeding rack 5 includes a receiving block 501, which is installed on the conveying frame 4. Two sets of clamping plates 502 are symmetrically and movably installed on the receiving block 501. Rubber blocks 503 are fixedly installed on the clamping plates 502. A support block 504 is arranged between the two sets of rubber blocks 503 and is fixedly installed on the receiving block 501. A movable frame 505 is installed inside the support block 504. A spring 506 is set on the movable frame 505. A bearing rod 507 is fixedly connected to the lower end of the movable frame 505. Two sets of inclined grooves 5051 are symmetrically opened on both sides of the movable frame 505. A pin 5021 is set at the lower end of the clamping plate 502. The end of the pin 5021 is located in the inclined groove 5051. The end of the bearing rod 507 is slidably connected to the outer ring of the guide ring 9. The outer ring of the guide ring 9 is composed of a first annular surface 901, an inclined surface 902, and a second annular surface 903. Two sets of mounting grooves 5011 are symmetrically opened on the receiving block 501. Two sets of guide posts 5012 are symmetrically installed in the mounting grooves 5011. The clamping plate 502 is slidably connected to the two sets of guide posts 5012. Sliding grooves 5052 are opened on both sides of the movable frame 505. The sliding grooves 5052 are slidably connected to the slide rails 5053. The slide rails 5053 are fixedly installed in the receiving block 501.

[0024] Specifically, the conveying mechanism 3 consists of a set of chains and two sets of sprockets, the cutting mechanism 6 consists of a set of transmission rods and three sets of cutting blades, and the grinding mechanism 7 consists of a set of transmission rods and three sets of grinding blades, with the thickness of the grinding blades being equal to the thickness of the cutting blades. Appendix Figure 1The middle arrow indicates the loading point. Initially, a set of conveyor frames 4 is located at the loading point. When angle steel needs to be processed, a set of workpieces 10 is placed on the four sets of unloading racks 5 of the set of conveyor frames 4 located at the loading point by a robotic arm. The workpieces 10 are located between two sets of rubber blocks 503 and on the support block 504. At the same time, two sets of motors drive two sets of transmission rods to rotate, causing the cutting disc and grinding disc to rotate at high speed. Then, a set of transmission shafts 2 are driven by a motor to rotate. The transmission shafts 2 drive two sets of sprockets to rotate. The two sets of sprockets drive two sets of chains and several sets of conveyor frames 4 to perform circular motion. The direction from the loading point to the cutting mechanism 6 is the direction of circular motion. The conveyor frames 4 located at the loading point drive the four sets of unloading racks 5 and the workpieces 10 to rotate. The workpiece 10 moves towards the cutting mechanism 6. Simultaneously, the end of the pressure rod 507 on the feeding rack 5 slides along the first annular surface 901. When the end of the pressure rod 507 slides to the inclined surface 902, the inclined surface 902 pushes the pressure rod 507, causing the pressure rod 507 to drive the movable frame 505 to move upwards along the two sets of slide rails 5053. The movable frame 505 compresses the spring 506. At the same time, the ends of the two sets of pins 5021 slide along the inclined groove 5051. Guided by the inclined groove 5051, the two sets of clamping plates 502 move towards each other along the corresponding guide posts 5012. The two sets of clamping plates 502 drive the corresponding rubber blocks 503 to clamp the workpiece 10, causing the rubber blocks 503 to deform until the end of the pressure rod 507 slides from the inclined surface 902 to the second annular surface 903, thus... Workpiece 10 is fixed between two sets of clamping plates 502. As the end of the pressure rod 507 slides along the second annular surface 903, workpiece 10 will pass through three sets of cutting blades, which will cut workpiece 10 into four segments until the next set of conveyor frames 4 moves to the loading point. At this time, the circular motion is paused, and the next set of workpieces 10 is placed on the next set of conveyor frames 4. Then the circular motion continues, and the workpiece 10 cut into four segments will pass through three sets of grinding blades. The rotating grinding blades will pass through the gaps cut on workpiece 10. During the process of the grinding blades passing through the gaps, the grinding blades grind the two sets of cutting surfaces. During the grinding process, the end of the pressure rod 507 continues to slide along the second annular surface 903. When the end of the pressure rod 507 slides from the second annular surface 903 to the first annular surface... On 901, under the rebound force of spring 506, the two sets of clamping plates 502 are released from fixing the workpiece 10. At the same time, under the action of gravity, the workpiece 10 cut into four sections will automatically fall into the material box 8 below, realizing the automatic unloading of the workpiece 10. The above operation is repeated in a cycle. Compared with the prior art, the above solution automatically completes the entire process of loading, clamping, cutting, grinding and unloading without manual intervention, which improves the automation rate of the device. Secondly, the sprocket and chain conveying mechanism 3 is adopted, and the circumferential motion of the conveying frame 4 is realized by motor drive, which can realize the continuous processing of the workpiece 10, improve the processing efficiency of the workpiece 10, and when the grinding disc passes through the workpiece 10, the grinding disc can grind the two sets of cutting surfaces at the same time, which greatly improves the grinding efficiency of the workpiece 10.

[0025] Furthermore, two sets of limiting plates 101 are symmetrically installed on the frame 1, and the two sets of limiting plates 101 are used to position the workpiece 10.

[0026] Specifically, when the workpiece 10 is placed on the four sets of feeding racks 5, the workpiece 10 is located between the two sets of limiting plates 101. When the feeding rack 5 drives the workpiece 10 to make a circular motion, the workpiece 10 will move along the two sets of limiting plates 101 until the workpiece 10 is fixed on the feeding rack 5. Then the workpiece 10 will be removed from the two sets of limiting plates 101 to prevent the workpiece 10 from shifting before it is fixed.

[0027] Example 2: Figures 5 to 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the conveyor frame 4 includes two sets of fixing blocks 401, the two sets of fixing blocks 401 are respectively fixedly connected to two sets of conveying mechanisms 3, four sets of crossbars 402 are fixedly installed between the two sets of fixing blocks 401, an L-shaped block 404 is fixedly connected to one set of fixing blocks 401, the end of the cross-shaped telescopic frame 403 is connected to the L-shaped block 404, four sets of nodes on the cross-shaped telescopic frame 403 are respectively connected to four sets of receiving blocks 501, four sets of through holes 5013 are opened on the receiving blocks 501, the four sets of through holes 5013 are respectively slidably connected to the four sets of crossbars 402, a receiving rod 5014 is installed on one set of receiving blocks 501, a guide groove is opened on the guide ring 9, the lower end of the receiving rod 5014 is located in the guide groove, the guide groove consists of a first annular groove 904, two sets of inclined grooves 905, and a second annular groove 906. The 06 component comprises a grinding mechanism 7, which includes a fixed frame 701, with both ends of the fixed frame 701 fixedly mounted on the frame 1, a rotating rod 702 rotatably mounted inside the fixed frame 701, three sets of reciprocating lead screws 703 rotatably mounted on the fixed frame 701 at equal intervals, two sets of movable plates 704 symmetrically arranged on the reciprocating lead screws 703, and a grinding disc 705 rotatably mounted at the lower end of the movable plate 704. The grinding disc 705 is fitted onto the rotating rod 702. The fixed frame 701 has three sets of rectangular grooves 7011 equidistantly opened, and a sliding rod 7012 is fixedly installed in the rectangular grooves 7011. The sliding rod 7012 slidably connects the two sets of movable plates 704. The rotating rod 702 has three sets of rectangular bars 7021 arranged at equal angles, and the inner ring of the grinding disc 705 has three sets of guide grooves 7051 arranged at equal angles. The guide grooves 7051 slidably connect the rectangular bars 7021.

[0028] Specifically, as the grinding disc continues to grind the cutting surface, the wear of the contact surface between the grinding disc and the cutting surface will increase. Since the grinding disc is relatively thin, it is easy to wear out, which means that the grinding disc needs to be replaced. However, replacing the grinding disc is troublesome, takes a long time, and affects the processing efficiency of the workpiece 10. The rotating rod 702 is driven by a motor to rotate, and the rotating rod 702 drives the grinding disc 705 to rotate through three sets of rectangular bars 7021. After the workpiece 10 is cut into four sections by the three sets of cutting discs, the workpiece 10 cut into four sections moves towards the grinding mechanism 7 along with the four sets of feeding racks 5. At this time, the end of the receiving rod 5014 on one set of feeding racks 5 will first slide along the first annular groove 904, and then the end of the receiving rod 5014 will slide from the first annular groove 904 into a set of inclined grooves 905. Within 05, guided by the inclined groove 905, the receiving rod 5014 drives the corresponding receiving block 501 to slide along the four sets of crossbars 402. Simultaneously, the receiving block 501 drives the scissor-type telescopic frame 403 to extend. The extended scissor-type telescopic frame 403 drives the remaining three sets of receiving blocks 501 to move, increasing the distance between the four segments of angle steel cut from the workpiece 10, until the end of the receiving rod 5014 slides into the second annular groove 906, maintaining the increased distance between the angle steel segments. The end of the receiving rod 5014 slides along the second annular groove 906. Every two sets of grinding discs 705 will pass between the two sets of angle steel. The two sets of grinding discs 705 grind the cut surfaces of the two sets of angle steel respectively. After the cut surfaces are ground, the end of the receiving rod 5014 slides into another set of inclined grooves 905. Guided by the other set of inclined grooves 905, the distance between the cut angle steels returns to the initial state. When the grinding surface of the grinding discs 705 is worn, the distance between the cut angle steels increases. Rotating the reciprocating screw 703 causes the two sets of movable plates 704 to move in opposite directions along the slide rod 7012. The two sets of movable plates 704 drive the two sets of grinding discs 705 to move in opposite directions along the rotating rod 702, adjusting the distance between the grinding discs 705 and the cutting surface, thereby maintaining a good grinding effect of the grinding discs 705 on the cutting surface. Since the distance between the grinding discs 705 and the cutting surface can be adjusted, it not only avoids frequent replacement of the grinding discs 705, but also increases the service life of the grinding discs 705.

[0029] Working principle: A robotic arm places a set of workpieces 10 onto four sets of feeding racks 5 of a set of conveyor frames 4 located at the loading point. The workpieces 10 are positioned between two sets of rubber blocks 503 and on support blocks 504. Simultaneously, two sets of motors drive two sets of transmission rods to rotate, causing both the cutting disc and the grinding disc to rotate at high speed. Then, a set of transmission shafts 2 are driven by a motor to rotate, which in turn drives two sets of sprockets to rotate. The two sets of sprockets drive two sets of chains, which, together with several sets of conveyor frames 4, to perform circular motion. The direction of circular motion is from the loading point to the cutting mechanism 6. The conveyor frames 4 located at the loading point drive... The four sets of feeding racks 5, along with the workpieces 10, move towards the cutting mechanism 6. Simultaneously, the end of the pressure rod 507 on the feeding rack 5 slides along the first annular surface 901. When the end of the pressure rod 507 slides to the inclined surface 902, the inclined surface 902 pushes the pressure rod 507, causing the pressure rod 507 to drive the movable frame 505 upwards along the two sets of slide rails 5053. The movable frame 505 compresses the spring 506. At the same time, the ends of the two sets of pins 5021 slide along the inclined groove 5051. Guided by the inclined groove 5051, the two sets of clamping plates 502 move towards each other along the corresponding guide posts 5012. Plate 502 drives the corresponding rubber block 503 to clamp the workpiece 10, causing the rubber block 503 to deform until the end of the pressure rod 507 slides from the inclined surface 902 to the second annular surface 903, fixing the workpiece 10 between the two sets of clamping plates 502. As the end of the pressure rod 507 slides along the second annular surface 903, the workpiece 10 will pass through three sets of cutting blades, which will cut the workpiece 10 into four segments until the next set of conveyor frames 4 moves to the loading point. At this time, the circular motion is paused, and the next set of workpieces 10 is placed on the next set of conveyor frames 4. Then the circular motion continues, and the workpiece 10 is cut into four segments. The workpiece 10 will pass through three sets of grinding discs. The rotating grinding discs will pass through the gaps cut on the workpiece 10. During the process of the grinding discs passing through the gaps, the grinding discs grind the two sets of cutting surfaces. During the grinding process, the end of the pressure rod 507 continues to slide along the second annular surface 903. When the end of the pressure rod 507 slides from the second annular surface 903 to the first annular surface 901, under the action of the rebound force of the spring 506, the two sets of clamps 502 will release the fixation of the workpiece 10. At the same time, under the action of gravity, the workpiece 10 cut into four sections will automatically fall into the material box 8 below, realizing the automatic unloading of the workpiece 10. The above operation is repeated in a cycle. The rotating rod 702 is driven by a motor to rotate. The rotating rod 702 drives the grinding disc 705 to rotate through three sets of rectangular bars 7021. After the workpiece 10 is cut into four sections by the three sets of cutting discs, the four sections of workpiece 10 move towards the grinding mechanism 7 along with the four sets of feeding racks 5. At this time, the end of the receiving rod 5014 on one set of feeding racks 5 will first slide along the first annular groove 904. Then, the end of the receiving rod 5014 slides from the first annular groove 904 into a set of inclined grooves 905. Under the guidance of the inclined grooves 905, the receiving rod 5014 drives the corresponding receiving block 501 to slide along the four sets of crossbars 402. At the same time, the receiving block 501 drives the cross-scissor telescopic frame 403 to extend. The extended cross-scissor telescopic frame 403 drives the other three sets of receiving blocks 501 to move, increasing the distance between the four sections of angle steel cut from workpiece 10. The end of the receiving rod 5014 slides into the second annular groove 906, keeping the distance between the angle steels increased. As the end of the receiving rod 5014 slides along the second annular groove 906, every two sets of grinding discs 705 will pass between the two sets of angle steels. The two sets of grinding discs 705 grind the cut surfaces of the two sets of angle steels respectively. After the cut surfaces are ground, the end of the receiving rod 5014 slides into another set of inclined grooves 905. Under the guidance of the other set of inclined grooves 905, the distance between the cut angle steels returns to the initial state. When the grinding surface of the grinding discs 705 is worn, due to the increased distance between the cut angle steels, the reciprocating screw 703 is rotated, causing the two sets of movable plates 704 to move in opposite directions along the slide rod 7012. The two sets of movable plates 704 drive the two sets of grinding discs 705 to move in opposite directions along the rotating rod 702, adjusting the distance between the grinding discs 705 and the cut surfaces.
