Description

Technical Field

[0001] The present invention relates to the technical field of processing equipment, and specifically to a shearing and curling equipment for metal product processing. Background Art

[0002] During the mechanical processing process, metal molds are usually required. The open end of the metal mold is relatively sharp and easy to cut the user. Therefore, curling treatment needs to be carried out at the mouth of the metal mold;

[0003] However, when the existing shearing and curling equipment performs shearing and curling, when encountering products of different sizes, due to insufficient accuracy of the feeding mechanism or unstable clamping, the shearing position deviates from the design requirements, affecting the alignment of the subsequent curling process, and further affecting the curling quality of the product. At the same time, when the existing shearing and curling equipment processes products of different thicknesses, it is not optimized for metals of different thicknesses or materials, resulting in problems such as excessive curling deformation, wrinkling or springback. At the same time, the coordination between shearing and curling is inconsistent, resulting in poor synchronism when the two processes are integrated. For example, curling is carried out before the material has been fully reset after shearing, resulting in stress concentration or distortion of the finished product.

[0004] Therefore, a shearing and curling equipment for metal product processing is needed to improve the above problems. Summary of the Invention

[0010] As a preferred embodiment of the present invention, the shearing and curling assembly includes an installation base, which is installed on the outer wall of the top of the fixed bracket. A servo motor is installed on the outer wall of the installation base. A rotating shaft is installed on the driving shaft of the servo motor.

[0015] As a preferred embodiment of the present invention, the guiding support block is located on one side of the arc-shaped clamping plate. The control panel is electrically connected to a driving motor, an electric control cylinder, an electric control telescopic rod, a servo motor, an electric control magnet, a stepping motor, and a magnetic displacement sensor through wires.

[0016] Compared with the prior art, by setting a support assembly in the shearing and curling equipment for metal product processing, the present invention can achieve a better fixing effect on the processed product. The control panel cooperatively controls the electric control cylinder and the electric control telescopic rod to achieve precise fixing of the metal cylinder. The electric control cylinder drives the rotating rod to push the limiting plate to rotate around the rotating shaft, driving the arc-shaped clamping plate to radially fit the outer wall of the metal cylinder, forming a bilateral clamping force. When the electric control telescopic rod contracts, the fixed plate is pulled through the shaft rod, causing the arc-shaped clamping plate to axially contract, generating a clamping force in the front and rear directions. The guiding support block contacts the inner wall of the metal cylinder to provide radial support, enhancing the overall fixing stability, thereby solving the problem that the feeding mechanism has insufficient accuracy or unstable clamping, resulting in the shearing position deviating from the design requirements, affecting the alignment of the subsequent curling process, and further affecting the curling quality of the product.

[0017] In the present invention, by setting a shearing and curling component in the shearing and curling equipment for metal product processing, good synchronization of the two processes of shearing and curling of the metal cylinder can be achieved. The stepping motor drives the threaded rod to drive the moving plate to move horizontally. The magnetic displacement sensor real-time feeds back the position signal to the control panel to ensure that the moving plate accurately stops at the set position. Subsequently, the servo motor drives the rotating base to drive the shearing blade to rotate to complete the cutting of the end face of the metal cylinder. After the cutting is completed, the stepping motor moves the moving plate in the reverse direction. At the same time, the electro-magnet is powered off to release the limit slider, and the limit spring rebounds to drive the curling knife to move outwards and fit the port of the metal cylinder. When the servo motor rotates again, the curling knife rotates synchronously with the mounting plate to complete the curling process. The cutting and curling functions are integrated on the same rotating platform. Through the horizontal displacement of the moving plate and the linkage control of the limit slider, seamless connection of the two processes is achieved, improving synchronization and processing efficiency, thereby solving the problem that the coordination between shearing and curling is inconsistent, resulting in poor synchronization when the two processes are integrated. For example, curling is performed before the material has been fully reset after shearing, resulting in stress concentration or distortion of the finished product.

[0018] In the present invention, by setting a support component in the shearing and curling equipment for metal product processing, the position of the curling knife can be adjusted according to the wall thickness of the metal cylinder, and the position of the guiding support block can be adjusted according to the wall thickness of the metal cylinder. This will cause the guiding support block to move on the inner wall of the guiding sleeve, exactly making the guiding plate located at a suitable position in the inner cavity of the metal cylinder. At the same time, the limit slider drives the curling knife to clamp at the port of the metal cylinder. Subsequently, the limit bolt is tightened to limit and fix the guiding support block, and the distance between the guiding plate and the inner wall of the metal cylinder can be adjusted at any time according to the wall thickness of the processed product, so that the curling knife clamps at the port of the metal cylinder, facilitating subsequent processing, thereby solving the problem that when processing products of different thicknesses, no optimization is carried out for metals of different thicknesses or materials, resulting in excessive deformation, wrinkling or springback of the curling.

An installation plate 1105 is installed on the outer wall of the rotating base 1104. A limiting chute 1106 is opened on the outer wall of the installation plate 1105. Limiting sliders 1107 are slidably connected to the opposite inner walls of the limiting chute 1106. A guide rod 1108 is installed on the outer wall of the limiting slider 1107. One end of the guide rod 1108 penetrates through the installation plate 1105 and extends to the outer wall of the installation plate 1105. The connection mode between the guide rod 1108 and the installation plate 1105 is a sliding connection. A limiting spring 1109 is installed on one side of the guide rod 1108 and on the outer wall of the limiting slider 1107. One end of the limiting spring 1109 is connected to the inner wall of the limiting chute 1106. Two groups of limiting springs 1109 are provided and are respectively located on the opposite inner walls of the limiting chute 1106. An electric control magnet 1110 is provided on one side of the limiting slider 1107 and on the inner wall of the limiting chute 1106. The connection mode between the electric control magnet 1110 and the limiting slider 1107 is a magnetic connection. A curling knife 1111 is rotatably connected to the opposite inner walls of the limiting slider 1107. A guide plate 1112 is installed on one side of the curling knife 1111 and on the side wall of the limiting slider 1107 through screws. A guide sleeve 1113 is embedded in the outer wall of the guide plate 1112. A guide support block 1114 is slidably connected to the inner wall of the guide sleeve 1113. A limiting bolt 1115 is threadedly connected to one side of the guide support block 1114 and on the outer wall of the guide sleeve 1113. One end of the limiting bolt 1115 limits the guide support block 1114. A threaded rod 1116 is rotatably connected to the side wall of the installation plate 1105. A stepping motor 1117 is installed at one end of the threaded rod 1116. A moving plate 1118 is threadedly connected to the outer wall of the threaded rod 1116. The moving plate 1118 is slidably connected to the side wall of the installation plate 1105. A positioning magnet 1119 is provided on the outer wall of the moving plate 1118. A magnetic displacement sensor 1120 is installed on the side wall of the rotating base 1104 and on one side of the positioning magnet 1119. A tool holder 1122 is installed on the outer wall of the moving plate 1118 through an installation rod 1121. A shearing blade 1123 is inserted and installed on the bottom outer wall of the tool holder 1122;

[0032] Based on the above structural features and connection relationships, after the curling knife 1111 finishes curling the metal cylinder 9, only need to apply a thrust to the guide rod 1108, and then the guide rod 1108 applies a thrust to the limit slider 1107, causing the limit slider 1107 to move horizontally on the inner wall of the limit chute 1106. When the limit slider 1107 moves to one side of the electromagnet 1110, turn on the switch of the control panel 6, and then the electromagnet 1110 magnetically adsorbs the limit slider 1107. At the same time, when the limit slider 1107 moves horizontally, it will cause the limit slider 1107 to stretch and reset the limit spring 1109;

[0033] Among them, the guiding support block 1114 is located on one side of the arc-shaped clamping plate 1013. Under the action that the control panel 6 is electrically connected to the drive motor 5, the electric control cylinder 1003, the electric control telescopic rod 1012, the servo motor 1102, the electromagnet 1110, the stepping motor 1117 and the magnetic displacement sensor 1120 through wires, the device is powered on, and then the control panel 6 controls the drive motor 5, the electric control cylinder 1003, the electric control telescopic rod 1012, the servo motor 1102, the electromagnet 1110, the stepping motor 1117 and the magnetic displacement sensor 1120 to operate.

[0034] When the shearing and curling equipment for metal products in this solution is working, place the metal cylinder 9 to be processed on the base surface of the sliding base 8, and then turn on the switch of the control panel 6. Then the control panel 6 controls the drive motor 5 to operate. When the drive motor 5 operates, the drive shaft of the drive motor 5 will drive the threaded connecting rod 4 to rotate, and then the threaded connecting rod 4 drives the sliding base 8 to move upward through threaded connection. The sliding base 8 moves upward on the outer wall of the limit slide rail 7, and then the metal cylinder 9 moves to the processing station;

[0035] When the metal cylinder 9 moves to a proper position, it causes the control panel 6 to control the operation of the electric control cylinder 1003. When the electric control cylinder 1003 operates, one end of the electric control cylinder 1003 applies a thrust to the limiting plate 1007 through the rotating rod 1004. When the limiting plate 1007 receives the thrust from the rotating rod 1004, the limiting plate 1007 rotates on the outer wall of the rotating shaft 1006, and then the limiting plate 1007 drives the arc-shaped clamping plate 1013 to fit on the outer wall of the metal cylinder 9 through the fixing plate 1009 for fixation. At this time, the metal cylinder 9 is subjected to the left and right clamping forces of the arc-shaped clamping plates 1013 on both sides. Meanwhile, the control panel 6 controls the electric control telescopic rod 1012 to contract. When the electric control telescopic rod 1012 contracts inward, the electric control telescopic rod 1012 applies an inward pulling force to the fixing plate 1009 through the shaft rod 1011, and then the fixing plate 1009 drives the arc-shaped clamping plate 1013 to contract, causing the metal cylinder 9 to be subjected to the front and back clamping forces of the arc-shaped clamping plates 1013 on both sides. Meanwhile, the inner wall of the metal cylinder 9 is supported by the guiding support block 1114, so that the fixing effect of the metal cylinder 9 is better, thus solving the problem that the feeding mechanism has insufficient precision or unstable clamping, resulting in the deviation of the shearing position from the design requirements, affecting the alignment of the subsequent curling process, and further affecting the curling quality of the product;

[0036] The control panel 6 controls the operation of the stepping motor 1117, and the driving shaft of the stepping motor 1117 drives the threaded rod 1116 to operate. The threaded rod 1116 drives the moving plate 1118 to move horizontally through threaded connection, and then the moving plate 1118 moves horizontally on the outer wall of the mounting plate 1105. When the moving plate 1118 moves to a proper position, the positioning magnet 1119 moves to one side of the magnetic displacement sensor 1120, and then the magnetic displacement sensor 1120 generates data. The electric signal generated by the magnetic displacement sensor 1120 is conducted to the control panel 6 through the wire. When the set parameters are reached, the control panel 6 controls the stepping motor 1117 to stop operating, and then the moving plate 1118 moves to a proper position. Subsequently, the control panel 6 controls the operation of the servo motor 1102, so that the servo motor 1102 drives the rotating base 1104 to rotate through the rotating shaft 1103, and then the rotating base 1104 drives the moving plate 1118 to rotate through the mounting plate 1105. When the moving plate 1118 rotates, the moving plate 1118 drives the tool holder 1122 and the shearing blade 1123 to rotate through the mounting rod 1121, so that the shearing blade 1123 cuts the end face of the metal cylinder 9;

[0037] After the end face of the metal cylinder 9 is cut by the cutting blade 1123, the stepping motor 1117 pushes the moving plate 1118 to move laterally to one side through the threaded rod 1116. At the same time, the control panel 6 controls the power-off of the electromagnet 1110 to lose magnetism, so that the limit slider 1107 loses the magnetic fixation of the electromagnet 1110, and then the stretched limit spring 1109 rebounds and contracts, which will cause the limit spring 1109 to drive the limit slider 1107 to move laterally on the inner wall of the limit chute 1106. At the same time, the limit slider 1107 drives the guide rod 1108 to move on the inner wall of the mounting plate 1105, and then the limit slider 1107 drives the curling knife 1111 to move outward respectively, which will cause the curling knife 1111 to fit and fix at the port of the metal cylinder 9. When the servo motor 1102 drives the rotating base 1104 to rotate through the rotating shaft 1103, and then the rotating base 1104 drives the mounting plate 1105 to rotate through the mounting plate 1105, the mounting plate 1105 will drive the curling knife 1111 to curl the metal cylinder 9 through the limit slider 1107. Since the curling and cutting structures are integrated into one structure, the synchronization of the two processes is good, thus solving the problem that the synchronization of shearing and curling is inconsistent, resulting in poor synchronization when the two processes are integrated. For example, curling is carried out before the material is fully reset after shearing, resulting in stress concentration or distortion of the finished product;

[0038] By applying a thrust to the guiding support block 1114, the guiding support block 1114 is made to fit on the inner wall of the metal cylinder 9. Under the interaction of the guiding support block 1114 and the metal cylinder 9, the position of the guiding support block 1114 is adjusted according to the wall thickness of the metal cylinder 9, which will cause the guiding support block 1114 to move on the inner wall of the guiding sleeve 1113, just making the guiding plate 1112 located at a suitable position in the inner cavity of the metal cylinder 9. At the same time, the limit slider 1107 drives the curling knife 1111 to be stuck at the port of the metal cylinder 9. Subsequently, the limit bolt 1115 is tightened to limit and fix the guiding support block 1114, and the distance between the guiding plate 1112 and the inner wall of the metal cylinder 9 can be adjusted at any time according to the wall thickness of the processed product, so that the curling knife 1111 is stuck at the port of the metal cylinder 9, facilitating subsequent processing, thus solving the problem of excessive curling deformation, wrinkling or springback caused by not optimizing for metals of different thicknesses or materials when processing products of different thicknesses.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made therein without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
