Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, specifically to a shearing and edge-rolling device for processing metal products. Background Technology

[0002] Metal molds are often used in machining processes. The opening of the metal mold is sharp and can easily cut the user. Therefore, it is necessary to roll the edges of the metal mold near the opening.

[0003] However, existing shearing and curling equipment has several problems when dealing with products of different sizes. Insufficient precision in the feeding mechanism or unstable clamping causes the shearing position to deviate from the design requirements, affecting the alignment of subsequent curling processes and consequently impacting the quality of the curled product. Furthermore, existing shearing and curling equipment is not optimized for different thicknesses or materials of metal, resulting in excessive deformation, wrinkling, or springback during curling. Inconsistent coordination between shearing and curling leads to poor synchronization during the integration of the two processes. For example, curling may occur before the material has fully returned to its original position after shearing, causing stress concentration or product distortion.

[0004] Therefore, a shearing and edge-rolling device for metal product processing is needed to improve the above-mentioned problems. Summary of the Invention

[0005] To address the problem that existing shearing and edge-rolling equipment for metal product processing is not optimized for different thicknesses or materials, resulting in excessive deformation, wrinkling, or springback of the rolled edges, this invention provides a shearing and edge-rolling device for metal product processing to solve the above-mentioned problems.

[0010] As a preferred embodiment of the present invention, the shearing and hemming assembly includes a mounting base, which is mounted on the top outer wall of a fixed bracket. A servo motor is mounted on the outer wall of the mounting base, and a rotating shaft is mounted on the drive shaft of the servo motor. One end of the rotating shaft passes through the mounting base and extends to a rotating base mounted on the outer wall of the fixed bracket. A mounting plate is mounted on the outer wall of the rotating base. A limit groove is formed on the outer wall of the mounting plate. A limit slider is slidably connected to the inner wall opposite to the limit groove. A guide rod is mounted on the outer wall of the limit slider. One end of the guide rod passes through the mounting plate and extends to the outer wall of the mounting plate. The guide rod and the mounting plate are connected by a sliding connection. A limit spring is mounted on one side of the guide rod and on the outer wall of the limit slider.

[0011] As a preferred embodiment of the present invention, one end of the limiting spring is connected to the inner wall of the limiting slide groove, wherein two sets of limiting springs are provided and are respectively located on opposite inner walls of the limiting slide groove, and an electrically controlled magnet is provided on one side of the limiting slider and on the inner wall of the limiting slide groove, wherein the electrically controlled magnet and the limiting slider are connected by magnetic connection.

[0012] As a preferred embodiment of the present invention, a curling knife is rotatably connected to the opposing inner wall of the limiting slider, a guide plate is screwed onto one side of the curling knife and located on the side wall of the limiting slider, a guide sleeve is embedded in the outer wall of the guide plate, and a guide support block is slidably connected to the inner wall of the guide sleeve.

[0013] As a preferred embodiment of the present invention, a limiting bolt is threadedly connected to one side of the guide support block and on the outer wall of the guide sleeve, wherein one end of the limiting bolt limits the guide support block, a threaded rod is rotatably connected to the side wall of the mounting plate, wherein a stepper motor is installed at one end of the threaded rod, and a movable plate is threadedly connected to the outer wall of the threaded rod, wherein the movable plate is slidably connected to the side wall of the mounting plate.

[0014] As a preferred embodiment of the present invention, a positioning magnetic block is provided on the outer wall of the movable plate, wherein a magnetic displacement sensor is installed on one side of the positioning magnetic block and on the side wall of the rotating base, and a blade holder is installed on the outer wall of the movable plate via a mounting rod, and a shearing blade is inserted and removed from the bottom outer wall of the blade holder.

[0015] As a preferred embodiment of the present invention, the guide support block is located on one side of the arc-shaped clamping plate, and the control panel is connected to the drive motor, the electric cylinder, the electric telescopic rod, the servo motor, the electric magnet, the stepper motor and the magnetic displacement sensor by wires, and the connection method is electrical connection.

[0016] Compared with existing technologies, this invention achieves better product fixation by incorporating a support assembly in a metal product processing shearing and edge-rolling device. The control panel coordinates the control of the electrically controlled cylinder and the electrically controlled telescopic rod to achieve precise fixation of the metal cylinder. The electrically controlled cylinder drives the rotating rod to push the limiting plate to rotate around the axis, causing the arc-shaped clamping plate to radially adhere to the outer wall of the metal cylinder, forming a double-sided clamping force. When the electrically controlled telescopic rod retracts, it pulls the fixing plate through the shaft, causing the arc-shaped clamping plate to retract axially, generating a clamping force in the front-to-back direction. The guide support block contacts the inner wall of the metal cylinder, providing radial support and enhancing overall fixation stability. This solves the problem of insufficient precision or unstable clamping in the feeding mechanism, leading to deviations in the shearing position from design requirements, affecting the alignment of subsequent edge-rolling processes, and consequently impacting the edge-rolling quality of the product.

[0017] This invention achieves good synchronization between the shearing and edge-rolling processes of a metal cylinder by setting a shearing and edge-rolling component in a shearing and edge-rolling equipment for metal product processing. A stepper motor drives a threaded rod, which moves the moving plate laterally. A magnetic displacement sensor provides real-time position feedback to the control panel, ensuring that the moving plate stops precisely at the set position. Subsequently, a servo motor drives a rotating base to rotate the shearing blade, completing the end face cutting of the metal cylinder. After cutting, the stepper motor moves the moving plate in the opposite direction, and at the same time, the electromagnet is de-energized, releasing the limit slider. The limit spring rebounds, driving the edge-rolling blade to move outward and fit against the end of the metal cylinder. When the servo motor rotates again, the edge-rolling blade rotates synchronously with the mounting plate, completing the edge-rolling process. The cutting and edge-rolling functions are integrated into the same rotating platform. Through the linkage control of the lateral displacement of the moving plate and the limit slider, the two processes are seamlessly connected, improving synchronization and processing efficiency. This solves the problem of inconsistent coordination between shearing and edge-rolling, which leads to poor synchronization when the two processes are integrated. For example, edge-rolling occurs before the material is fully reset after shearing, resulting in stress concentration or product distortion.

[0018] This invention, by incorporating a support assembly in a metal product processing shearing and edge-rolling device, enables the adjustment of the edge-rolling blade position based on the metal cylinder's wall thickness. The position of the guide support block is also adjusted according to the cylinder's wall thickness, allowing it to move along the inner wall of the guide sleeve. This positions the guide plate precisely within the metal cylinder's cavity. Simultaneously, a limiting slider engages the edge-rolling blade at the metal cylinder's port. Tightening the limiting bolt then secures the guide support block. This allows for the adjustment of the distance between the guide plate and the metal cylinder's inner wall based on the product's wall thickness, ensuring the edge-rolling blade remains engaged at the cylinder's port for subsequent processing. This solves the problem of excessive edge deformation, wrinkling, or springback caused by not optimizing for different metal thicknesses or materials when processing products of varying thicknesses.

[0031] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The shearing and hemming assembly 11 includes a mounting base 1101, which is mounted on the top outer wall of the fixed bracket 2. A servo motor 1102 is mounted on the outer wall of the mounting base 1101. A rotating shaft 1103 is mounted on the drive shaft of the servo motor 1102. One end of the rotating shaft 1103 passes through the mounting base 1101 and extends to a rotating base 1104 mounted on the outer wall of the fixed bracket 2. A mounting plate 1105 is mounted on the outer wall of the rotating base 1104. A limiting groove 1106 is formed on the outer wall of the mounting plate 1105. A limiting slider 1107 is slidably connected on the inner wall opposite to the limiting groove 1106. A guide rod 1108 is installed on the outer wall of the 07. One end of the guide rod 1108 passes through the mounting plate 1105 and extends to the outer wall of the mounting plate 1105. The guide rod 1108 and the mounting plate 1105 are connected by a sliding connection. A limit spring 1109 is installed on one side of the guide rod 1108 and on the outer wall of the limit slider 1107. One end of the limit spring 1109 is connected to the inner wall of the limit groove 1106. Two sets of limit springs 1109 are provided and are located on opposite inner walls of the limit groove 1106. An electrically controlled magnet 1110 is installed on one side of the limit slider 1107 and on the inner wall of the limit groove 1106. The control magnet 1110 and the limiting slider 1107 are connected by magnetic connection. A curling blade 1111 is rotatably connected to the opposing inner wall of the limiting slider 1107. A guide plate 1112 is screwed onto one side of the curling blade 1111 and located on the side wall of the limiting slider 1107. 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 threaded onto one side of the guide support block 1114 and located on the outer wall of the guide sleeve 1113. One end of the limiting bolt 1115 limits the guide support block 1114. (The last sentence appears to be incomplete and possibly refers to a mounting plate.) A threaded rod 1116 is rotatably connected to the side wall of the mounting plate 1105. A stepper motor 1117 is installed at one end of the threaded rod 1116. A movable plate 1118 is threadedly connected to the outer wall of the threaded rod 1116. The movable plate 1118 is slidably connected to the side wall of the mounting plate 1105. A positioning magnetic block 1119 is provided on the outer wall of the movable plate 1118. A magnetic displacement sensor 1120 is installed on one side of the positioning magnetic block 1119 and on the side wall of the rotating base 1104. A blade holder 1122 is installed on the outer wall of the movable plate 1118 via a mounting rod 1121. A shearing blade 1123 is inserted and removed from the bottom outer wall of the blade holder 1122.

[0032] Based on the above structural features and connection relationships, after the edge-rolling knife 1111 finishes rolling the metal cylinder 9, only a pushing force needs to be applied to the guide rod 1108, which in turn applies a pushing force to the limiting slider 1107, causing the limiting slider 1107 to move laterally on the inner wall of the limiting groove 1106. When the limiting slider 1107 moves to one side of the electromagnet 1110, the switch of the control panel 6 is turned on, which causes the electromagnet 1110 to magnetically attract the limiting slider 1107. At the same time, when the limiting slider 1107 moves laterally, it will stretch and reset the limiting spring 1109.

[0033] The guide support block 1114 is located on one side of the arc-shaped clamping plate 1013. The control panel 6 is connected to the drive motor 5, the electric cylinder 1003, the electric telescopic rod 1012, the servo motor 1102, the electric magnet 1110, the stepper motor 1117, and the magnetic displacement sensor 1120 via wires. The device is powered on by the control panel 6, which then controls the drive motor 5, the electric cylinder 1003, the electric telescopic rod 1012, the servo motor 1102, the electric magnet 1110, the stepper motor 1117, and the magnetic displacement sensor 1120 to operate.

[0034] When the metal product processing shearing and edge-rolling equipment of this solution is working, the metal cylinder 9 to be processed is placed on the base surface of the sliding base 8, and then the switch of the control panel 6 is turned on, so that the control panel 6 controls the drive motor 5 to run. When the drive motor 5 runs, the drive shaft of the drive motor 5 drives the threaded connecting rod 4 to rotate, so that the threaded connecting rod 4 drives the sliding base 8 to move upward through the threaded connection. The sliding base 8 moves upward on the outer wall of the limit slide rail 7, so that the metal cylinder 9 moves to the processing station.

[0035] When the metal cylinder 9 is moved to the appropriate position, the control panel 6 will control the electric cylinder 1003 to operate. When the electric cylinder 1003 operates, one end of the electric cylinder 1003 will apply a pushing force to the limiting plate 1007 via the rotating rod 1004. When the limiting plate 1007 is pushed by the rotating rod 1004, it will rotate on the outer wall of the rotating shaft 1006. This will cause the limiting plate 1007 to drive the arc-shaped clamping plate 1013 to adhere to the outer wall of the metal cylinder 9 for fixation via the fixing plate 1009. 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. At the same time, the control panel 6 controls the electric cylinder 1003 to operate. When the telescopic rod 1012 retracts, it applies an inward pulling force to the fixing plate 1009 via the shaft 1011. This causes the fixing plate 1009 to retract the arc-shaped clamping plate 1013, resulting in the metal cylinder 9 being clamped by the arc-shaped clamping plates 1013 on both sides. At the same time, the inner wall of the metal cylinder 9 is supported by the guide support block 1114, which improves the fixing effect of the metal cylinder 9. This solves the problem of insufficient precision or unstable clamping of the feeding mechanism, which causes the shearing position to deviate from the design requirements, affecting the alignment of the subsequent edge rolling process and thus affecting the edge rolling quality of the product.

[0036] The stepper motor 1117 is controlled by the control panel 6, causing its drive shaft to rotate the threaded rod 1116. This threaded rod 1116, through a threaded connection, moves the moving plate 1118 laterally, causing it to move laterally on the outer wall of the mounting plate 1105. When the moving plate 1118 reaches the desired position, the positioning magnet 1119 moves to one side of the magnetic displacement sensor 1120, causing the magnetic displacement sensor 1120 to generate data. This generates an electrical signal, which is transmitted to the control panel 6 via wires. When the set parameters are reached... When the count is up, the control panel 6 will stop the stepper motor 1117, thereby moving the moving plate 1118 to the appropriate position. Then, the control panel 6 will control the servo motor 1102 to run, so that the servo motor 1102 drives the rotating base 1104 to rotate via the rotating shaft 1103. In turn, the rotating base 1104 drives the moving plate 1118 to rotate via the mounting plate 1105. When the moving plate 1118 rotates, it will drive the knife holder 1122 and the shearing blade 1123 to rotate via 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 shearing blade 1123, the stepper motor 1117 pushes the moving plate 1118 to move laterally to one side via the threaded rod 1116. At the same time, the control panel 6 controls the electromagnet 1110 to lose power and magnetism, thereby causing the limit slider 1107 to lose the magnetic fixation of the electromagnet 1110. This causes the stretched limit spring 1109 to rebound and contract, which in turn causes the limit spring 1109 to drive the limit slider 1107 to move laterally on the inner wall of the limit groove 1106. Simultaneously, the limit slider 1107 drives the guide rod 1108 to move on the inner wall of the mounting plate 1105, thereby causing the limit slider 1107 to drive the edge-rolling blade 1111 to move laterally. Moving outwards will cause the edge-rolling blade 1111 to fit against the end of the metal cylinder 9 and be fixed. When the servo motor 1102 drives the rotating base 1104 to rotate via the rotating shaft 1103, and then the rotating base 1104 drives the mounting plate 1105 to rotate via the mounting plate 1105, the mounting plate 1105 will drive the edge-rolling blade 1111 to roll the metal cylinder 9 via the limit slider 1107. Since the edge-rolling and shearing structures are integrated into one structure, the synchronization of the two processes is good, thereby solving the problem of inconsistent coordination between shearing and edge-rolling, which leads to poor synchronization when the two processes are integrated. For example, if the material is not fully reset after shearing before edge-rolling, it will cause stress concentration or product distortion.

[0038] By applying a pushing force to the guide support block 1114, the guide support block 1114 is made to fit against the inner wall of the metal cylinder 9. Under the interaction between the guide support block 1114 and the metal cylinder 9, the position of the guide support block 1114 is adjusted according to the wall thickness of the metal cylinder 9, which will cause the guide support block 1114 to move on the inner wall of the guide sleeve 1113, so that the guide plate 1112 is located in the appropriate position in the inner cavity of the metal cylinder 9. At the same time, the limiting slider 1107 drives the edge-rolling knife 1111 to be stuck at the port of the metal cylinder 9. Then the limiting bolt 1115 is tightened so that the limiting bolt 1115 limits and fixes the guide support block 1114. The distance between the guide 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 edge-rolling knife 1111 is stuck at the port of the metal cylinder 9, which facilitates subsequent processing. This solves the problem of excessive deformation, wrinkling or springback of the edge-rolling when processing products of different thicknesses without optimization for metals of different thicknesses or materials.
