Description

Technical Field

[0001] This invention belongs to the field of chain plate bending and punching technology, specifically a chain plate automatic feeding bending and punching device. Background Technology

[0002] Currently, the production process for chain transition plates involves punching blanks, punching bending, punching holes, bench drill deburring, punching shaping, and bench drill reaming. Each process is done manually, which poses a high safety risk. When operating the punching machine, the operator's hands must reach into the working area of ​​the punching machine (outside the mold area, using tweezers to place the material into the mold). This process is inefficient, complex, and labor-intensive. Therefore, an automatic feeding, bending, and punching equipment for chain plates is designed to combine multiple processes and produce them simultaneously. A robotic arm is also added for feeding, thus achieving automated production.

[0003] The existing automatic feeding, bending, and punching equipment for chain plates includes a feeding table, a handling robotic arm, a punch press, a finished product frame, and an electrical control box. The punch press can bend, punch, and shape the chain plates in one operation. The handling robotic arm is equipped with four sets of suction cups, which pick up the chain plates from the feeding table and transport them to the bending, punching, and shaping areas on the punch press. Finally, the finished products are placed into the finished product frame, thus realizing the processing of the chain plates.

[0004] In the above-mentioned scheme, before processing the chain plate, it is necessary to place the chain plate on the feeding table. Only one set of chain plates can be placed at a time, which means that it needs to be replenished after each material is taken out. This replenishment method has low automation rate and low feeding efficiency. To this end, the present invention provides an automatic feeding, bending and punching device for chain plates. 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 the present invention to solve its technical problem is as follows: The automatic feeding, bending and punching device for chain plates of the present invention includes a base, a feeding tray mechanism installed on the base, an electrical control cabinet in front of the feeding tray mechanism, a translational robotic arm installed on the back of the electrical control cabinet, four sets of suction fixtures installed at equal intervals on the translational robotic arm, a punch press installed on one side of the feeding tray mechanism, three sets of modules installed at equal intervals inside the punch press, a material frame placed at one end of the punch press, the feeding tray mechanism includes a fixed base, the fixed base is fixedly installed on the base, a turntable rotatably installed on the fixed base, four sets of feeding tools arranged at equal angles on the turntable, feeding grooves for placing chain plates on the feeding tools, a toothed ring fixedly fitted on the turntable, a first gear meshing with the toothed ring, the first gear rotatably installed on one end of a fixed plate, the other end of the fixed plate being fixedly connected to the upper end of the fixed base, and a feeding box fixedly installed on the base, the lower end of the feeding box being attached to the upper surface of the turntable;

[0007] The feeding box can pre-store multiple sets of chain plates to be processed. Through the coordinated setting of the feeding box, the feeding tool, and the feeding trough, the feeding tool can automatically feed a chain plate once every 90 degrees of rotation of the turntable. This not only improves the automation rate of the device, but also improves the feeding efficiency of the device.

[0008] Preferably, the feeding device includes a movable tube mounted on a turntable, a feeding block fixedly connected to one end of the movable tube, a movable groove on the feeding block, four sets of corrective devices movably installed in the movable groove, the area enclosed by the four sets of corrective devices forming the feeding groove, a movable rod movably inserted into the movable tube, a first spring sleeved on the movable rod, an L-shaped rack fixedly connected to one end of the movable rod, a second gear meshing with the L-shaped rack, the second gear rotatably installed in the feeding block, four sets of rectangular grooves opened in the movable groove, guide posts fixedly installed in the rectangular grooves, a slider provided on the corrective device, the slider slidably connected to the guide posts, four sets of arc-shaped grooves provided at equal angles on the second gear, a pin provided at the lower end of the slider, the lower end of the pin located in the arc-shaped groove, a first guide ring fixedly fitted on the fixed seat, the other end of the movable rod slidably connected to the outer ring of the first guide ring, and a first protrusion provided on the first guide ring for pushing the movable rod.

[0009] As the second gear rotates, the lower ends of the four sets of pins slide along the four sets of arc grooves. Guided by the arc grooves, the four sets of pins drive the corresponding sliders and the correctors to close together in the middle, so that the four sets of correctors clamp the chain plate and correct its position. When the feeding device rotates to the specified degree, the other end of the movable rod is exactly offset from the first protrusion. Under the action of the first spring rebound force, the clamping of the chain plate by the four sets of correctors is released. Since the four sets of correctors are movable, the volume inside the feeding trough can be adjusted, thus not only preventing the chain plate from not being able to enter the feeding trough, but also preventing the chain plate from being misaligned.

[0010] Preferably, the feeding device also includes a movable sleeve, which is slidably fitted onto the movable tube. A second spring is fitted onto the movable tube. An L-shaped rod is fixedly connected to the movable sleeve. Four sets of clearance grooves are opened at equal angles on the turntable. The movable tube is rotatably installed in the clearance grooves. The movable sleeve is slidably connected to the clearance grooves. The feeding tray mechanism also includes a waste box, which is located below the turntable. A second guide ring is also fixedly fitted onto the fixed seat. A roller is rotatably installed at the end of the L-shaped rod. The roller is rotatably connected to the outer ring of the second guide ring. A second protrusion for pushing the roller is provided on the second guide ring. Several sets of protrusions are provided on the outer ring of the first guide ring. Two sets of spiral grooves are opened on the movable tube. Two sets of convex shafts are symmetrically arranged in the inner ring of the movable sleeve. The convex shafts are located in the spiral grooves.

[0011] As the roller rolls along the second protrusion, keeping the discharge block in an inverted state, the other end of the movable rod will be squeezed by the protrusion. Since there are multiple sets of protrusions, the four sets of correctors are in a continuous opening and closing state. During the opening and closing process, the correctors will hit the inner wall of the movable groove, causing the metal scraps attached to the inner wall of the movable groove to be shaken off, until the roller is offset from the second protrusion and the other end of the movable rod is offset from the protrusion. Under the action of the second spring rebound force, the discharge device returns to the initial state, which not only realizes the pouring of metal scraps in the movable groove into the waste box, but also makes the metal scraps in the movable groove cleaner.

[0012] The beneficial effects of this invention are as follows:

[0013] 1. The feeding box can pre-store multiple sets of chain plates to be processed. Through the coordinated setting of the feeding box, the feeding tool, and the feeding trough, the feeding tool can automatically feed a chain plate once every 90 degrees of rotation of the turntable. This not only improves the automation rate of the device, but also improves the feeding efficiency of the device.

[0014] 2. When the turntable and the four sets of feeding devices rotate 90 degrees together, the movable rod will rotate with the feeding devices, and the other end of the movable rod will slide against the outer ring of the first guide ring. The other end of the movable rod will be squeezed by the first protrusion on the first guide ring, causing the movable rod to drive the L-shaped rack to move towards the second gear. The movable rod compresses the first spring, and the moving L-shaped rack drives the second gear to rotate. As the second gear rotates, the lower ends of the four sets of pins slide along the four sets of arc grooves respectively. Under the guidance of the arc grooves, the four sets of pins drive the corresponding sliders and the correctors to close together in the middle, so that the four sets of correctors clamp the chain plate and realize the position correction of the chain plate. When the feeding device rotates to the desired degree, the other end of the movable rod is exactly offset from the first protrusion. Under the action of the rebound force of the first spring, the clamping of the four sets of correctors on the chain plate is released. Since the four sets of correctors are movable, the volume inside the feeding trough can be adjusted, thereby not only preventing the chain plate from not being able to enter the feeding trough, but also preventing the chain plate from being misaligned.

[0015] 3. Continue driving the turntable and feeding device to rotate 90 degrees. The L-shaped rod will rotate together with the feeding device, causing the roller to roll along the outer ring of the second guide ring. The roller will be squeezed by the second protrusion, causing the roller to push the L-shaped rod and the movable sleeve together. The movable sleeve slides along the clearance groove and compresses the second spring. At the same time, the movable sleeve drives the two sets of convex shafts to slide along the two sets of spiral grooves. Under the guidance of the spiral grooves, the movable tube and the feeding block rotate 180 degrees together, causing the metal scraps accumulated in the movable groove to be poured into the scrap box. As the roller moves along the second guide ring... The protrusion rolls, keeping the discharge block in an inverted state. The other end of the movable rod will be squeezed by the protrusion. Since there are multiple sets of protrusions, the four sets of correction tools are in a continuous opening and closing state. During the opening and closing process, the correction tools will hit the inner wall of the movable groove, causing the metal scraps attached to the inner wall of the movable groove to be shaken off until the rollers are offset from the second protrusion and the other end of the movable rod is offset from the protrusion. Under the action of the second spring rebound force, the discharge tool returns to the initial state. This not only realizes the pouring of metal scraps in the movable groove into the waste box, but also makes the metal scraps in the movable groove cleaner. Attached Figure Description

[0027] 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.

[0028] Example 1: As Figures 1 to 3 As shown in the embodiment of the present invention, an automatic feeding, bending, and punching device for chain plates includes a base 1, a feeding tray mechanism 2 mounted on the base 1, an electrical control cabinet 3 located in front of the feeding tray mechanism 2, a translational robotic arm 4 mounted on the back of the electrical control cabinet 3, four sets of suction fixtures 5 evenly spaced on the translational robotic arm 4, a punch press 6 located on one side of the feeding tray mechanism 2, three sets of modules 7 evenly spaced inside the punch press 6, and a material frame 8 placed at one end of the punch press 6. The feeding tray mechanism 2 includes a fixed base 201, which is fixedly mounted on the base 1 and rotates... A turntable 202 is mounted on a fixed base 201. Four sets of feeding tools 203 are set at equal angles on the turntable 202. The feeding tools 203 are provided with feeding grooves 31 for placing chain plates. A toothed ring 204 is fixedly fitted on the turntable 202. A first gear 205 meshes with the toothed ring 204. The first gear 205 is rotatably mounted on one end of a fixed plate 206. The other end of the fixed plate 206 is fixedly connected to the upper end of the fixed base 201. A feeding box 207 is fixedly mounted on the machine base 1. The lower end of the feeding box 207 is attached to the upper surface of the turntable 202.

[0029] Specifically, the three modules 7 are bending mold, punching mold, and forming mold. The translational robotic arm 4 can move horizontally and vertically. Multiple sets of chain plates to be processed are stacked in the loading box 207. When processing of the chain plates is required, initially, one set of chain plates is located in the feeding slot 31 of one set of feeding fixtures 203. The motor drives the first gear 205 to rotate, causing the first gear 205 to drive the gear ring 204, along with the turntable 202 and the four sets of feeding fixtures 203, to rotate 90 degrees. Figure 2 The middle arrow indicates the direction of rotation, causing a set of feeding devices 203 to rotate the corresponding chain plate 90 degrees, positioning the chain plate below the first set of suction fixtures 5. During rotation, the upper surface of the turntable 202 blocks the lower end of the loading box 207 until the next set of feeding devices 203 rotates to below the loading box 207, causing the chain plate in the loading box 207 to automatically fall into the feeding slot 31 of the next set of feeding devices 203. Then, the translational robotic arm 4 moves the suction fixture 5, causing the first set of suction fixtures 5 to pick up the chain plate and place it into the bending die of the punch press 6. Then, the translational robotic arm 4 returns the suction fixture 5 to its initial position, and the bending die bends the chain plate. During this process, the turntable 202 and the fourth set of suction fixtures 5 continue to be driven. The feeding fixtures 203 rotate 90 degrees together. After the chain plate is bent, the first set of suction fixtures 5 picks up the chain plate again and places it into the bending die by the translational robotic arm 4. The second set of suction fixtures 5 places the bent chain plate into the punching die. The above operation is repeated so that the chain plate passes through the bending die, punching die, and shaping die in sequence and is finally dropped into the material frame 8 to complete the processing of the chain plate. Compared with the prior art, the feeding box 207 can pre-store multiple sets of chain plates to be processed. Through the coordinated setting of the feeding box 207, the feeding fixtures 203, and the feeding trough 31, the feeding fixtures 203 can automatically feed a chain plate once every 90 degrees of rotation of the turntable 202. This not only improves the automation rate of the device, but also improves the feeding efficiency of the device.

[0030] like Figures 4 to 6As shown, the feeding device 203 includes a movable tube 2031, which is mounted on the turntable 202. A feeding block 2032 is fixedly connected to one end of the movable tube 2031. A movable groove 2033 is formed on the feeding block 2032. Four sets of correction tools 2034 are movably installed in the movable groove 2033. The area enclosed by the four sets of correction tools 2034 is the feeding groove 31. A movable rod 2035 is movably inserted into the movable tube 2031. A first spring 2036 is sleeved on the movable rod 2035. An L-shaped rack 2037 is fixedly connected to one end of the movable rod 2035. A second gear 2038 meshes with the L-shaped rack 2037. The second gear 2038 is rotatably mounted. Inside the material feeding block 2032, four sets of rectangular grooves 331 are provided in the movable groove 2033. Guide posts 332 are fixedly installed in the rectangular grooves 331. A slider 341 is provided on the calibrator 2034. The slider 341 is slidably connected to the guide posts 332. Four sets of arc grooves 381 are provided at equal angles on the second gear 2038. A pin 342 is provided at the lower end of the slider 341. The lower end of the pin 342 is located in the arc groove 381. A first guide ring 2011 is fixedly fitted on the fixed seat 201. The other end of the movable rod 2035 is slidably connected to the outer ring of the first guide ring 2011. A first protrusion 111 for pushing the movable rod 2035 is provided on the first guide ring 2011.

[0031] Specifically, the chain plates to be processed are produced by punching. Punching will cause burrs on the edges of the chain plates. Since the internal dimensions of the feeding groove 31 and the loading box 207 are closely matched with the chain plates, the presence of burrs will cause the chain plates to get stuck in the loading box 207 or prevent them from entering the feeding groove 31, thus affecting the processing efficiency of the chain plates. In the design, the internal cross-sectional dimension of the loading box 207 is slightly larger than that of the chain plates. When the feeding fixture 203 is located directly below the loading box 207, the four sets of correction fixtures 2034 The volume of the enclosed area is larger than the volume of the chain plate, so the chain plate can smoothly fall from the feeding box 207 into the feeding trough 31 enclosed by the four sets of correction fixtures 2034. When the turntable 202 and the four sets of feeding fixtures 203 rotate together by 90 degrees, the movable rod 2035 will rotate with the feeding fixtures 203, and the other end of the movable rod 2035 will slide against the outer ring of the first guide ring 2011. The other end of the movable rod 2035 will be affected by the first protrusion 111 on the first guide ring 2011. The compression causes the movable rod 2035 to move the L-shaped rack 2037 towards the second gear 2038. The movable rod 2035 compresses the first spring 2036, and the moving L-shaped rack 2037 drives the second gear 2038 to rotate. As the second gear 2038 rotates, the lower ends of the four sets of pins 342 slide along the four sets of arc-shaped grooves 381. Guided by the arc-shaped grooves 381, the four sets of pins 342 drive the corresponding sliders 341, along with the corrector 2034, to close towards the center. The four sets of correction tools 2034 clamp the chain plate to correct its position. When the feeding tool 203 rotates to 90 degrees, the other end of the movable rod 2035 is offset from the first protrusion 111. Under the rebound force of the first spring 2036, the clamping of the four sets of correction tools 2034 on the chain plate is released. Since the four sets of correction tools 2034 are movable, the volume inside the feeding trough 31 can be adjusted, thereby not only preventing the chain plate from failing to enter the feeding trough 31, but also preventing the chain plate from being misaligned.

[0032] Example 2: Figures 7 to 9As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the feeding device 203 further includes a movable sleeve 2039, which is slidably fitted onto the movable tube 2031. The second spring 2040 is fitted onto the movable tube 2031. The L-shaped rod 2041 is fixedly connected to the movable sleeve 2039. Four sets of clearance grooves 2021 are equally spaced on the turntable 202. The movable tube 2031 is rotatably installed in the clearance grooves 2021. The movable sleeve 2039 is slidably connected to the clearance grooves 2021. The feeding tray mechanism 2 further includes a waste box 208. The waste box 208 is positioned... Below the turntable 202, the fixed base 201 also has a second guide ring 2012 fixedly mounted. The end of the L-shaped rod 2041 is rotatably mounted with a roller 2042. The roller 2042 is tumbledly connected to the outer ring of the second guide ring 2012. The second guide ring 2012 is provided with a second protrusion 121 for pushing the roller 2042. The outer ring of the first guide ring 2011 is provided with several sets of protrusions 112. The movable tube 2031 is provided with two sets of spiral grooves 311. The inner ring of the movable sleeve 2039 is symmetrically provided with two sets of convex shafts 391, which are located in the spiral grooves 311.

[0033] Specifically, punching not only creates burrs on the chain plate but also generates a large amount of metal scrap. Some smaller metal scraps adhere to the chain plate and fall into the movable groove 2033. Since the straightening fixture 2034 is movable within the movable groove 2033, the metal scraps accumulate in the groove, hindering its movement and increasing the friction between the straightening fixture 2034 and the inner wall of the movable groove 2033. This reduces the service life of the straightening fixture 2034 and the unloading block 2032. When the suction fixture... 5. After removing the chain plate from the feeding device 203, continue driving the turntable 202 and the feeding device 203 to rotate 90 degrees. The L-shaped rod 2041 will rotate together with the feeding device 203. The L-shaped rod 2041 will drive the roller 2042 to roll along the outer ring of the second guide ring 2012. The roller 2042 will be squeezed by the second protrusion 121, causing the roller 2042 to push the L-shaped rod 2041 and the movable sleeve 2039 to move together. The movable sleeve 2039 slides along the relief groove 2021 and compresses the second spring 20. 40. Simultaneously, the movable sleeve 2039 drives the two sets of convex shafts 391 to slide along the two sets of spiral grooves 311. Guided by the spiral grooves 311, the movable tube 2031 and the discharge block 2032 rotate 180 degrees together, causing the metal scraps accumulated in the movable groove 2033 to be poured into the scrap box 208. As the roller 2042 rolls along the second protrusion 121, keeping the discharge block 2032 in an inverted state, the other end of the movable rod 2035 will be squeezed by the protrusion 112. Since there are multiple sets of protrusions 112, the four sets of correction tools 2034... In a continuously opening and closing state, during the opening and closing process, the correction tool 2034 will hit the inner wall of the movable groove 2033, causing the metal scraps attached to the inner wall of the movable groove 2033 to be shaken off until the roller 2042 is offset from the second protrusion 121 and the other end of the movable rod 2035 is offset from the protrusion 112. Under the rebound force of the second spring 2040, the discharge tool 203 returns to the initial state, which not only realizes the pouring of metal scraps in the movable groove 2033 into the waste box 208, but also makes the metal scraps in the movable groove 2033 cleaner.

[0034] Working principle: The motor drives the first gear 205 to rotate, which in turn drives the gear ring 204, along with the turntable 202 and the four sets of feeding devices 203, to rotate 90 degrees. Figure 2The middle arrow indicates the direction of rotation, causing a set of feeding devices 203 to rotate the corresponding chain plate 90 degrees, positioning the chain plate below one side of the first set of suction fixtures 5. During rotation, the upper surface of the turntable 202 blocks the lower end of the loading box 207 until the next set of feeding devices 203 rotates to below the loading box 207, causing the chain plate inside the loading box 207 to automatically fall into the feeding slot 31 of the next set of feeding devices 203. Then, the translational robotic arm 4 moves the suction fixture 5, causing the first set of suction fixtures 5 to pick up the chain plate and place it into the bending die of the punch press 6. Then, by translating the robotic arm 4, the suction fixture 5 is returned to its initial position, and the chain plate is bent by the bending die. At the same time, during this process, the turntable 202 and the four sets of feeding tools 203 continue to rotate 90 degrees together. After the chain plate is bent, the first set of suction fixtures 5 is lifted by the translating robotic arm 4 and placed into the bending die. The second set of suction fixtures 5 places the bent chain plate into the punching die. The above operation is repeated so that the chain plate passes through the bending die, the punching die, and the shaping die in sequence, and is finally dropped into the material frame 8 to complete the processing of the chain plate.

[0035] When the feeding device 203 is directly below the feeding box 207, the volume of the area enclosed by the four sets of alignment devices 2034 is larger than the volume of the chain plate. Therefore, the chain plate can smoothly fall from the feeding box 207 into the feeding trough 31 enclosed by the four sets of alignment devices 2034. When the turntable 202 and the four sets of feeding devices 203 rotate together by 90 degrees, the movable rod 2035 will rotate with the feeding device 203, and the other end of the movable rod 2035 will slide against the outer ring of the first guide ring 2011. The other end of the movable rod 2035 will be squeezed by the first protrusion 111 on the first guide ring 2011, causing the movable rod 2035 to drive the L-shaped rack 2037 to move towards the second gear 2038. When the movable rod 2035 compresses the first spring 2036, the moving L-shaped rack 2037 drives the second gear 2038 to rotate. As the second gear 2038 rotates, the lower ends of the four sets of pins 342 slide along the four sets of arc grooves 381 respectively. Under the guidance of the arc grooves 381, the four sets of pins 342 drive the corresponding sliders 341 together with the correction fixtures 2034 to close in the middle, so that the four sets of correction fixtures 2034 clamp the chain plate and realize the position correction of the chain plate. When the feeding device 203 rotates to 90 degrees, the other end of the movable rod 2035 is exactly offset from the first protrusion 111. Under the rebound force of the first spring 2036, the clamping of the four sets of correction fixtures 2034 on the chain plate is released.

[0036] After the suction fixture 5 removes the chain plate from the discharge fixture 203, it continues to drive the turntable 202 and the discharge fixture 203 to rotate 90 degrees. The L-shaped rod 2041 will rotate together with the discharge fixture 203. The L-shaped rod 2041 will drive the roller 2042 to roll along the outer ring of the second guide ring 2012. The roller 2042 will be squeezed by the second protrusion 121, causing the roller 2042 to push the L-shaped rod 2041 and the movable sleeve 2039 to move together. The movable sleeve 2039 slides along the relief groove 2021 and compresses the second spring 2040. At the same time, the movable sleeve 2039 drives the two sets of convex shafts 391 to slide along the two sets of spiral grooves 311. Under the guidance of the spiral grooves 311, the movable tube 2031 and the discharge block 203... 2. Rotate 180 degrees together to pour the metal scrap accumulated in the movable groove 2033 into the scrap box 208. As the roller 2042 rolls along the second protrusion 121, keeping the discharge block 2032 in an inverted state, the other end of the movable rod 2035 will be squeezed by the protrusion 112. Since there are multiple sets of protrusions 112, the four sets of correction tools 2034 are in a state of continuous opening and closing. During the opening and closing process, the correction tools 2034 will hit the inner wall of the movable groove 2033, causing the metal scraps attached to the inner wall of the movable groove 2033 to be shaken off, until the roller 2042 is offset from the second protrusion 121 and the other end of the movable rod 2035 is offset from the protrusion 112. Under the rebound force of the second spring 2040, the discharge tool 203 returns to the initial state.
