Description

Technical Field

[0001] The invention belongs to the technical field of shearing and curling of metal products, in particular to a shearing and curling device for metal products. Background Art

[0002] The shearing and curling equipment is a kind of equipment used for metal product processing, which is mainly used for shearing and curling metal workpieces. The existing shearing and curling equipment has realized automatic control. Its working principle is to use the PLC control system to enable the shearing mechanism to cut the irregular and burred edges of metal products, and curl the edges after shearing, so as to realize the automatic operation of shearing and curling, and improve the processing efficiency and safety.

[0003] The patent with publication number CN118617119A discloses a shearing and curling device for processing metal products, including a shearing and curling device body, a shearing unit, and a curling unit. The shearing unit and the curling unit are both movably installed on the shearing and curling device body, and a base is arranged between the shearing unit and the curling unit. A pressure plate is arranged above the base, and the pressure plate is rotatably installed on the output shaft of the cylinder. Three groups of applicable mechanisms are installed at equal angles on the pressure plate. The applicable mechanism in this scheme can adjust the contact area according to the size of the metal workpiece, and by arranging U-shaped connecting blocks, circular rings and other components on the base, the base can support metal workpieces of different sizes, so that the device can be applicable to metal workpieces of different sizes, thereby improving the practicability of the device and facilitating the promotion of the device.

[0004] In the above scheme, only one metal workpiece can be placed on the base at a time. Therefore, after the metal workpiece is processed, the processed metal workpiece and the sheared edge materials need to be taken down from the base before the next group of metal workpieces to be processed can be placed. In this process, the taking and placing of the metal workpieces not only makes it impossible to continuously process the metal products, but also wastes a lot of time, thereby reducing the efficiency of metal product processing. For this reason, the present invention provides a metal product shearing and curling device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: a metal product shearing and curling device described in the present invention comprises a frame, a curling mechanism, and a shearing mechanism. The curling mechanism and the shearing mechanism are both movably mounted on the frame. A support frame is fixedly mounted on the frame. A driving mechanism is mounted on the support frame. A conversion disk is rotatably mounted on the frame. Three groups of placement racks for placing metal workpieces are rotatably mounted on the conversion disk. The driving mechanism comprises a rotating tube, the rotating tube is rotatably mounted on the support frame, a first gear fixedly sleeved on the upper end of the rotating tube, a rectangular shaft movably plugged into the rotating tube, a second gear meshing with the first gear, the second gear fixedly mounted on the output shaft of the motor, a fixed cover for pressing down the metal workpiece is fixedly connected to the lower end of the rectangular shaft, one end of a connecting plate is rotatably connected to the rectangular shaft, and the other end of the connecting plate is fixedly connected to a cylinder; During the process of cutting and curling the metal workpiece, the staff can load and unload the metal workpiece at the same time, thereby realizing continuous processing of the metal workpiece and improving the processing efficiency of the metal workpiece.

[0007] Preferably, the placement frame includes a rotating seat, which is rotatably mounted on the conversion disk, a support platform movably plugged into the rotating seat, a rectangular column fixedly connected to the lower end of the support platform, a spring sleeved on the rectangular column, the upper end of the pressure-bearing head is rotatably connected to the lower end of the rectangular column, two groups of arc-shaped side plates are symmetrically fixedly mounted on the pressure-bearing head, the rectangular column is movably plugged into the rotating seat, the lower end of the spring is fixedly connected to the inner wall of the rotating seat, the upper end of the spring is fixedly connected to the lower end of the support platform, an arc-shaped pad is fixedly mounted on the frame, the two groups of arc-shaped side plates respectively fit the inner ring and the outer ring of the arc-shaped pad, a roller is rotatably mounted on the lower end of the pressure-bearing head, the roller is rollingly connected to the arc-shaped pad, and the end of the arc-shaped pad is provided with an inclined surface for pushing the roller; Under the action of the spring rebound force, the support table together with the rectangular column and the pressure head moves downward until the roller reaches the conversion disk. At this time, the upper end surface of the support table is flush with the upper end surface of the conversion disk, and the metal workpiece and waste materials fall on the conversion disk. When taking materials, the staff can take the metal workpiece and waste materials from the conversion disk at the same time, which makes it more convenient for the staff to take materials and improves work efficiency.

[0008] Preferably, the placement rack also includes a receiving ring, an inner ring of the receiving ring is fixedly connected to two groups of arc side plates, four groups of guide pillars are fixedly connected to the upper end surface of the receiving ring, the upper ends of the four groups of guide pillars are connected to a movable ring, six groups of guide plates are installed at equal angles on the movable ring, three groups of annular grooves are opened at equal angles on the conversion disk, the three groups of rotating seats are respectively located in the inner rings of the three groups of annular grooves, and the three groups of movable rings are respectively located in the three groups of annular grooves, four groups of through holes are opened at the bottom of the annular grooves, and the four groups of guide pillars are respectively inserted into the four groups of through holes, and a material receiving mechanism is arranged on the outside of the frame, the material receiving mechanism includes a ramp platform, the ramp platform is fixedly installed on the frame, and one side of the ramp platform is in contact with the outer ring of the conversion disk, one end of the material blocking plate is fixedly connected to the ramp platform, and the material blocking is located on the conversion disk, and a conveyor belt mechanism for conveying metal workpieces is arranged at the lower end of the ramp platform; When the placement rack rotates to the loading point, the waste will be pushed out of the annular groove by the movable ring, and the staff only needs to take down the waste. Therefore, there is no need for the staff to sort the metal workpieces and waste. This not only avoids the occurrence of incorrect classification of metal workpieces and waste, but also makes it more convenient and quick for the staff to unload the materials.

[0009] The beneficial effects of the present invention are as follows: 1. During the process of cutting and curling the metal workpiece, the staff can load and unload the metal workpiece at the same time, thereby realizing continuous processing of the metal workpiece and improving the processing efficiency of the metal workpiece.

[0010] 2. When processing the metal workpiece, the metal workpiece sleeve is placed on the support table, and the upper end of the rotating seat supports the metal workpiece, the spring is in a stretched state, and the roller is located on the arc pad. When the metal workpiece is processed, the conversion disk drives the placement rack and the metal workpiece to rotate 120 degrees. The roller rolls along the upper end surface of the arc pad until the roller is offset from the arc pad. Under the action of the spring rebound force, the support table together with the rectangular column and the pressure head moves downward until the roller reaches the conversion disk. At this time, the upper end surface of the support table is flush with the upper end surface of the conversion disk, and the metal workpiece and the waste both fall on the conversion disk. When taking materials, the staff can take the metal workpiece and the waste from the conversion disk at the same time, which makes it more convenient for the staff to take materials and improves work efficiency.

[0011] 3. When the metal workpiece is processed, the conversion disk drives the placement rack to rotate 120 degrees together with the metal workpiece. The roller staggers the arc pad. Under the action of the spring rebound force, the pressure head drives the arc side plate together with the receiving ring to move downward. The receiving ring drives the movable ring into the annular groove through four sets of guide pillars, so that the waste also enters the annular groove. At this time, the outer ring of the metal workpiece is attached to the baffle plate. When the conversion disk rotates again, the metal workpiece is blocked by the baffle plate and cannot rotate with the conversion disk. However, the metal workpiece will move toward the ramp platform, so that the metal workpiece is displaced onto the ramp platform and slides along the ramp platform onto the conveyor belt mechanism. The metal workpiece is conveyed to the next workstation through the conveyor belt mechanism, thereby realizing the separation of the metal workpiece and the waste. When the placement rack rotates to the loading point, the waste will be pushed out of the annular groove by the movable ring, and the staff only needs to remove the waste. Therefore, there is no need for the staff to classify the metal workpiece and the waste, which not only avoids the classification errors of metal workpieces and waste, but also makes it more convenient and quick for the staff to unload materials.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] Embodiment 1, as Figure 1 and Figure 2As shown, a metal product shearing and curling device described in an embodiment of the present invention includes a frame 1, a curling mechanism 2, and a shearing mechanism 3. The curling mechanism 2 and the shearing mechanism 3 are both movably mounted on the frame 1. A support frame 4 is fixedly mounted on the frame 1, and a driving mechanism 5 is mounted on the support frame 4. A conversion disk 6 is rotatably mounted on the frame 1, and three groups of placement racks 7 for placing metal workpieces 8 are rotatably mounted on the conversion disk 6. The driving mechanism 5 includes a rotating tube 501, which is rotatably mounted on the support frame 4, a first gear 502 fixedly mounted on the upper end of the rotating tube 501, a rectangular shaft 503 movably inserted into the rotating tube 501, and a second gear 504 meshing with the first gear 502. The second gear 504 is fixedly mounted on the output shaft of the motor 505, and a fixed cover 506 for pressing down the metal workpiece 8 is fixedly connected to the lower end of the rectangular shaft 503, and one end of the connecting plate 507 is rotatably connected to the rectangular shaft 503, and the other end of the connecting plate 507 is fixedly connected to the cylinder 508.

[0024] Specifically, the principles of the crimping mechanism 2 and the shearing mechanism 3 are consistent with the crimping unit and the shearing unit in the shearing and crimping device for metal product processing disclosed in the patent with publication number CN118617119A. Figure 1 The loading point is just below the metal workpiece 8. When the metal workpiece 8 needs to be processed, the metal workpiece 8 is placed on a set of placement racks 7 located at the loading point, and then the conversion disk 6 is driven by the motor to rotate 120 degrees, and the rotation direction is the attachment. Figure 1The arrow indicates the direction, and the metal workpiece 8 will rotate with the placement rack 7, so that the metal workpiece 8 rotates to the right below the fixed cover 506, and then the cylinder 508 is started, so that the cylinder 508 pushes the connecting plate 507 together with the rectangular shaft 503 and the fixed cover 506 to move downward until the fixed cover 506 presses the metal workpiece 8, so that the metal workpiece 8 is clamped between the fixed cover 506 and the placement rack 7, and then the shearing mechanism 3 is started to move the shearing mechanism 3 to the edge of the metal workpiece 8, and then the second gear 504 is driven to rotate by the motor 505, and the second gear 504 drives the rotating tube 501 to rotate through the first gear 502, and the rotating tube 501 drives the rectangular shaft 503 together with the fixed cover 506, the metal workpiece 8, and the placement rack 7 to rotate. As the metal workpiece 8 rotates, the shearing mechanism 3 realizes the cutting of the edge of the metal workpiece 8. After cutting, the shearing mechanism 3 is withdrawn, and the curling mechanism 2 is started. The curling mechanism 2 curls the edge of the metal workpiece 8. During this process, the next group of metal workpieces 8 can be placed on the placement rack 7 located at the loading point. When the edge of the metal workpiece 8 is curled, the curling mechanism 2 is withdrawn, the motor 505 is paused, and the downward pressure of the fixed cover 506 on the metal workpiece 8 is released, and the conversion disk 6 is continued to be driven to rotate 120 degrees, so that the metal workpiece 8 after processing leaves the bottom of the fixed cover 506, and the next group of metal workpieces 8 will rotate to the bottom of the fixed cover 506. Similarly, the next group of metal workpieces 8 are cut and curled, and during the processing, the processed metal workpieces 8 and waste are taken off the placement rack 7, and the metal workpieces 8 to be processed are continued to be placed on the placement rack 7 located at the loading point, and the above operations are repeated in a cycle. Compared with the prior art, during the cutting and curling process of the metal workpiece 8, the staff can load and unload the metal workpiece 8 at the same time, thereby realizing continuous processing of the metal workpiece 8 and improving the processing efficiency of the metal workpiece 8.

[0025] like Figures 3 to 5 As shown, the placement rack 7 includes a rotating seat 701, the rotating seat 701 is rotatably mounted on the conversion disk 6, a support platform 702 that is movably plugged into the rotating seat 701, a rectangular column 703 that is fixedly connected to the lower end of the support platform 702, a spring 704 that is sleeved on the rectangular column 703, an upper end of a pressure head 705 that is rotatably connected to the lower end of the rectangular column 703, two sets of arc side plates 706 that are symmetrically fixedly mounted on the pressure head 705, the rectangular column 703 that is movably plugged into the rotating seat 701, and the spring 704 that is sleeved on the rectangular column 703. The lower end of the spring 704 is fixedly connected to the inner wall of the rotating seat 701, and the upper end of the spring 704 is fixedly connected to the lower end of the support platform 702. An arc-shaped pad 101 is fixedly installed on the frame 1, and two sets of arc-shaped side plates 706 are respectively fitted with the inner circle and the outer circle of the arc-shaped pad 101. A roller 7051 is rotatably installed at the lower end of the pressure head 705. The roller 7051 is rollingly connected to the arc-shaped pad 101, and the end of the arc-shaped pad 101 is provided with an inclined surface 102 for pushing the roller 7051.

[0026] Specifically, in the process of removing the processed metal workpiece 8 and the waste from the placement rack 7, the metal workpiece 8 is generally removed first, and then the waste is removed. This material removal method is cumbersome and inefficient. When the metal workpiece 8 is processed, the metal workpiece 8 is placed on the support table 702, and the upper end of the rotating seat 701 supports the metal workpiece 8, the spring 704 is in a stretched state, and the roller 7051 is located on the arc pad 101. When the metal workpiece 8 is processed, the conversion disk 6 drives the placement rack 7 and the metal workpiece 8 to rotate 120 degrees. The roller 7051 rolls along the upper end surface of the arc pad 101 until the roller 7051 is offset from the arc pad 101. Under the rebound force of spring 704, support platform 702, together with rectangular column 703 and pressure head 705, moves downward until roller 7051 reaches conversion disk 6. At this time, the upper end surface of support platform 702 is flush with the upper end surface of conversion disk 6, and metal workpiece 8 and waste material both fall on conversion disk 6. When taking materials, the staff can take metal workpiece 8 and waste material from conversion disk 6 at the same time. After taking materials, as conversion disk 6 rotates, roller 7051 will roll onto the inclined surface 102 at the end of arc-shaped pad 101, and inclined surface 102 pushes roller 7051, so that support platform 702 extends out of rotating seat 701, thereby making it more convenient for staff to take materials and improving work efficiency.

[0027] Embodiment 2, as Figures 6 to 8 As shown, compared with Example 1, another embodiment of the present invention is: the placement rack 7 also includes a receiving ring 707, the inner ring of the receiving ring 707 is fixedly connected to the two groups of arc-shaped side plates 706, and four groups of guide pillars 708 are fixedly connected to the upper end surface of the receiving ring 707. The upper ends of the four groups of guide pillars 708 are all connected to a movable ring 709, and six groups of guide plates 710 are installed at equal angles on the movable ring 709. Three groups of annular grooves 601 are opened at equal angles on the conversion plate 6. The three groups of rotating seats 701 are respectively located in the inner rings of the three groups of annular grooves 601, and the three groups of movable rings 70 9 are respectively located in three groups of annular grooves 601, four groups of through holes 602 are opened at the bottom of the annular grooves 601, and four groups of guide pillars 708 are respectively inserted into the four groups of through holes 602. A material receiving mechanism 9 is arranged on the outside of the frame 1, and the material receiving mechanism 9 includes a ramp platform 901, which is fixedly mounted on the frame 1, and one side of the ramp platform 901 is in contact with the outer ring of the conversion disk 6, one end of the baffle plate 902 is fixedly connected to the ramp platform 901, and the baffle is located on the conversion disk 6, and a conveyor belt mechanism 903 for conveying metal workpieces 8 is arranged at the lower end of the ramp platform 901.

[0028] Specifically, after the metal workpiece 8 and the waste are removed from the conversion disk 6, the staff is required to classify and place the metal workpiece 8 and the waste. This classification and placement method not only prolongs the material unloading time of the staff, but also makes it easy for the staff to make classification errors due to long-term work. The inner diameter of the waste is larger than the outer diameter surrounded by the six groups of guide plates 710, and the outer diameter of the waste is much smaller than the outer diameter of the movable ring 709. When the metal workpiece 8 is processed, the cut waste will fall onto the movable ring 709 under the guidance of the six groups of guide plates 710. When the metal workpiece 8 is processed, the conversion disk 6 drives the placement rack 7 to rotate 120 degrees together with the metal workpiece 8. The roller 7051 staggers the arc pad 101, and the spring 70 Under the action of the rebound force, the pressure head 705 drives the arc-shaped side plate 706 and the receiving ring 707 to move downward, and the receiving ring 707 drives the movable ring 709 to enter the annular groove 601 through the four sets of guide pillars 708, so that the waste also enters the annular groove 601. At this time, the outer ring of the metal workpiece 8 is attached to the baffle plate 902. When the conversion disk 6 rotates again, the metal workpiece 8 is blocked by the baffle plate 902 and cannot rotate with the conversion disk 6, but the metal workpiece 8 will move toward the ramp platform 901, so that the metal workpiece 8 is displaced onto the ramp platform 901, and slides down the ramp platform 901 to the conveyor belt mechanism 903, and the metal workpiece 8 is conveyed to the next station by the conveyor belt mechanism 903, and the conveying direction is attached. Figure 8 The middle arrow indicates the direction, thereby realizing the separation of the metal workpiece 8 and the waste. When the placement rack 7 rotates to the loading point, the waste will be pushed out of the annular groove 601 by the movable ring 709, and the staff only needs to take down the waste. Therefore, the staff does not need to classify the metal workpiece 8 and the waste, which not only avoids the occurrence of incorrect classification of the metal workpiece 8 and the waste, but also makes it more convenient and quick for the staff to unload the materials.

[0029] Working principle: Place the metal workpiece 8 on a set of placement racks 7 located at the loading point, and then drive the conversion disk 6 to rotate 120 degrees through the motor, and the rotation direction is Figure 1The arrow indicates the direction, and the metal workpiece 8 will rotate together with the placement rack 7, so that the metal workpiece 8 rotates to the bottom of the fixed cover 506, and then the cylinder 508 is started, so that the cylinder 508 pushes the connecting plate 507 together with the rectangular shaft 503 and the fixed cover 506 to move downward until the fixed cover 506 presses the metal workpiece 8, so that the metal workpiece 8 is clamped between the fixed cover 506 and the placement rack 7, and then the shearing mechanism 3 is started to move the shearing mechanism 3 to the edge of the metal workpiece 8, and then the second gear 504 is driven to rotate by the motor 505, and the second gear 504 drives the rotating tube 501 to rotate through the first gear 502, and the rotating tube 501 drives the rectangular shaft 503 together with the fixed cover 506, the metal workpiece 8, and the placement rack 7 to rotate. As the metal workpiece 8 rotates, the shearing mechanism 3 realizes the cutting of the edge of the metal workpiece 8. After the shearing is completed, the shearing mechanism 3 is withdrawn, and the curling mechanism 2 is started. The edge of the metal workpiece 8 is curled by the curling mechanism 2. During this process, the next group of metal workpieces 8 can be placed on the placement rack 7 located at the loading point. When the edge of the metal workpiece 8 is curled, the curling mechanism 2 is withdrawn, the motor 505 is paused, and the downward pressure of the fixed cover 506 on the metal workpiece 8 is released, and the conversion disk 6 is continued to be driven to rotate 120 degrees, so that the metal workpiece 8 after processing leaves the bottom of the fixed cover 506, and the next group of metal workpieces 8 will rotate to the bottom of the fixed cover 506. Similarly, the next group of metal workpieces 8 are cut and curled, and during the processing, the processed metal workpieces 8 and waste are taken off the placement rack 7, and the metal workpieces 8 to be processed are continued to be placed on the placement rack 7 located at the loading point, and the above operation is repeated in a cycle. When processing the metal workpiece 8, the metal workpiece 8 is placed on the support table 702, and the upper end of the rotating seat 701 holds the metal workpiece 8, the spring 704 is in a stretched state, and the roller 7051 is located on the arc pad 101. When the metal workpiece 8 is processed, the conversion disk 6 drives the placement rack 7 and the metal workpiece 8 to rotate 120 degrees. The roller 7051 rolls along the upper end surface of the arc pad 101 until the roller 7051 staggers the arc pad 101. Under the rebound force of the spring 704, the support table 702 together with the metal workpiece 8 rotates 120 degrees. The rectangular column 703 and the pressure head 705 move downward until the roller 7051 reaches the conversion disk 6. At this time, the upper end surface of the support platform 702 is flush with the upper end surface of the conversion disk 6. The metal workpiece 8 and the waste material both fall on the conversion disk 6. When taking materials, the staff can take the metal workpiece 8 and the waste material from the conversion disk 6 at the same time. After taking materials, as the conversion disk 6 rotates, the roller 7051 rolls onto the inclined surface 102 at the end of the arc-shaped pad 101, and the inclined surface 102 pushes the roller 7051, so that the support platform 702 extends out of the rotating seat 701. When the metal workpiece 8 is processed, the cut waste will fall onto the movable ring 709 under the guidance of the six sets of guide plates 710. When the metal workpiece 8 is processed, the conversion plate 6 drives the placement rack 7 and the metal workpiece 8 to rotate 120 degrees. The roller 7051 staggers the arc pad 101. Under the rebound force of the spring 704, the pressure head 705 drives the arc side plate 706 and the receiving ring 707 to move downward. The receiving ring 707 drives the movable ring 709 to enter the annular The metal workpiece 8 is moved to the inclined platform 901, and slides down the inclined platform 901 to the conveyor belt mechanism 903, and is conveyed to the next workstation by the conveyor belt mechanism 903. Figure 8 The middle arrow indicates the direction, thereby realizing separation of the metal workpiece 8 from the waste. When the placement rack 7 rotates to the loading point, the waste will be pushed out of the annular groove 601 by the movable ring 709, and the staff only needs to remove the waste.
