Description

Technical Field

[0001] This application relates to the field of metal product trimming machine technology, and more specifically, to an arc trimming device for metal product production. Background Technology

[0002] In the processing and production of metal products, some sheet metal products need to undergo arc-shaped edge trimming, or the arc edges of sheet metal products need to be trimmed in a straight line to remove excess parts or cut out guide groove structures. The usual trimming equipment is a metal product trimming machine, which can be widely used for trimming and trimming of various metal products such as aluminum alloys and magnesium alloys to achieve shaping and other processes. However, it is difficult to combine arc-shaped and straight-line trimming on the trimming machine, which means that sheet metal products need to be trimmed on trimming machines with different functions, making the processing procedure complicated. In view of this, we propose an arc-shaped trimming device for metal product production. Utility Model Content

[0004] The purpose of this application is to provide an arc-shaped edge-cutting device for metal product manufacturing, which solves the technical problems in the background art mentioned above. This edge-cutting device can facilitate the positioning, installation, and quick disassembly of sheet metal products. By setting a second cutter that moves in an arc direction, arc-shaped edge-cutting of sheet metal products can be achieved. By setting a second cutter that moves in a straight direction, straight edge-cutting of sheet metal products at multiple angles can be achieved. Thus, by combining arc and straight edge-cutting operations, complex edge-cutting processing of sheet metal products can be achieved, and the device is convenient to use and operate.

[0005] 2. Technical Solution

[0006] This application provides an arc-shaped trimming device for metal product manufacturing, comprising: a processing table and a sector-shaped seat threaded onto the processing table. A positioning mechanism and a hydraulic cylinder are fixedly mounted on the sector-shaped seat. A rotating device is installed at the piston rod end of the hydraulic cylinder. The rotating device includes a connecting plate, which is fixedly mounted on the piston rod end of the hydraulic cylinder. A rotating frame is rotatably mounted on the connecting plate, and a trimming mechanism is mounted on the rotating frame. The trimming mechanism includes:

[0007] A straight edge cutting mechanism includes a horizontal rail slidably mounted on a rotating frame, a slide block slidably mounted on the horizontal rail, a first protective cover fixedly mounted at the bottom end of the slide block, a third motor fixedly mounted on the first protective cover, and a first cutting blade drivenly connected to the output end of the third motor.

[0008] The arc-shaped cutting mechanism includes a second protective cover fixedly mounted on a rotating frame, a fourth motor fixedly mounted on the second protective cover, and a second cutting blade connected to the output end of the fourth motor.

[0009] By adopting the above technical solution, this device uses a sector-shaped seat fixedly installed on the upper limit of the processing table, and a hydraulic cylinder and positioning mechanism fixedly installed on the sector-shaped seat. The sector-shaped seat and positioning mechanism work together to achieve the positioning and installation of sheet metal products. The piston rod end of the hydraulic cylinder is driven by a rotating device to rotate the rotating frame, causing the straight edge cutting mechanism and the arc edge cutting mechanism installed on the rotating frame to move along the arc direction. The output end of the fourth motor drives the second cutter to rotate at high speed, and the second cutter moves in an arc direction, thereby performing arc edge cutting on the sheet metal products. When the rotating frame rotates to the required angle, the horizontal rail moves down along the rotating frame, causing the first cutter to contact the surface of the sheet metal products. The output end of the third motor drives the first cutter to rotate at high speed, and the first guard slides horizontally along the horizontal rail, allowing the first cutter to perform edge cutting in a straight direction. Thus, by combining arc and straight edge cutting operations, complex edge cutting processing of sheet metal products can be achieved, which is convenient to use and operate.

[0010] Optionally, the machining table is provided with a plurality of positioning holes arranged in a matrix, and the sector seat is fixed to the upper surface of the machining table by bolt threads.

[0011] By adopting the above technical solution, the processing table is equipped with multiple positioning holes arranged in a matrix, which makes it easy to position and install the sector-shaped seat. Furthermore, if the plate metal product has a perforated structure, bolts can be used for reinforcement and limiting.

[0012] Optionally, the sector-shaped seat is provided with a sector-shaped groove and an arc-shaped groove, and the first cutter is guided to move along the arc direction of the arc-shaped groove.

[0013] By adopting the above technical solution, the high-speed rotating first cutter moves along the arc of the arc groove with the first protective cover, which can realize the arc cutting edge processing of plate metal products. By setting the fan-shaped groove on the fan-shaped seat, if there is a protruding structure at the bottom of the plate metal product, it can be set in the fan-shaped groove, which facilitates the installation and processing of plate metal products.

[0014] Optionally, the positioning mechanism includes two strip plates, which are arranged vertically and fixedly mounted on the upper surface of the sector seat. Two screws are threaded onto each strip plate, and the screws are rotatably connected to an L-shaped block.

[0015] By adopting the above technical solution, the plate metal product is placed on the upper surface of the sector-shaped seat. The screw on the locking strip plate is used to clamp the edge of the plate metal product with the L-shaped block and the sector-shaped seat, thereby realizing the limiting and fixing treatment of the plate metal product.

[0016] Optionally, a first motor is fixedly installed on the bottom surface of the connecting plate, and a first gear is driven at the output end of the first motor. A rotating column is rotatably provided on the connecting plate, and the rotating column is fixedly sleeved with the rotating frame. A second gear is fixedly provided at the upper end of the rotating column, and the first gear and the second gear are meshed together.

[0017] By adopting the above technical solution, the output end of the first motor drives the first gear to rotate, which in turn drives the second gear to rotate the rotating column along the connecting plate. The rotating column can drive the rotating frame to rotate. When the piston rod of the hydraulic cylinder extends or retracts, the rotating frame can be driven to lift and lower through the connecting plate, thereby allowing the first cutter to adjust its installation height.

[0018] Optionally, the rotating frame includes a Y-shaped frame and a concave guide rail, the Y-shaped frame and the concave guide rail are fixedly connected, the Y-shaped frame is fixedly sleeved with the rotating column, the concave guide rail is slidably connected with the horizontal rail, and the concave guide rail is fixedly connected with the second protective cover.

[0019] By adopting the above technical solution, the rotating frame, which is fixedly connected by the Y-shaped frame and the concave guide rail, can drive the second protective cover and the horizontal rail to rotate together. The horizontal rail slides along the concave guide rail, thereby adjusting the installation height of the second cutter.

[0020] Optionally, an electric cylinder is fixedly mounted on the upper surface of the concave guide rail. The piston rod of the electric cylinder moves through the concave guide rail and is fixedly connected to the horizontal rail. A rack is fixedly mounted on the side of the horizontal rail. A second motor is fixedly mounted on the slide block. A third gear is driven to the output end of the second motor. The third gear meshes with the rack.

[0021] By adopting the above technical solution, the piston rod of the electric cylinder drives the horizontal rail to slide along the concave guide rail, while the second motor drives the third gear to rotate along the rack, which can cause the slide to drive the second cutter to move horizontally along the horizontal rail for processing.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] Reference Figures 1 to 4 This application provides an arc-shaped trimming device for metal product manufacturing, comprising: a processing table 1 and a sector-shaped seat 2 threadedly fixed to the processing table 1. A positioning mechanism 3 and a hydraulic cylinder 4 are fixedly mounted on the sector-shaped seat 2. A rotating device 5 is mounted on the piston rod end of the hydraulic cylinder 4. The rotating device 5 includes a connecting plate 51, which is fixedly mounted on the piston rod end of the hydraulic cylinder 4. A rotating frame 6 is rotatably mounted on the connecting plate 51, and a trimming mechanism is mounted on the rotating frame 6. The trimming mechanism includes:

[0031] The straight edge cutting mechanism 7 includes a horizontal rail 72 that is slidably mounted on a rotating frame 6, a slide block 76 that is slidably mounted on the horizontal rail 72, a first protective cover 77 that is fixedly mounted at the bottom end of the slide block 76, a third motor 78 that is fixedly mounted on the first protective cover 77, and a first cutter 79 that is driven to the output end of the third motor 78.

[0032] The curved edge trimming mechanism 8 includes a second protective cover 81 fixedly mounted on a rotating frame 6. A fourth motor 82 is fixedly mounted on the second protective cover 81, and the output end of the fourth motor 82 is connected to a second cutting blade 83. This device uses a sector-shaped seat 2 fixedly mounted on the upper limit of the processing table 1, and a hydraulic cylinder 4 and a positioning mechanism 3 fixedly mounted on the sector-shaped seat 2. The sector-shaped seat 2 and the positioning mechanism 3 work together to achieve the positioning and installation of sheet metal products. The piston rod end of the hydraulic cylinder 4 is rotated by a rotating device 5, causing the rotating frame 6 to rotate, thus moving the straight edge trimming mechanism 7 and the curved edge trimming mechanism 8 mounted on the rotating frame 6 along the curved direction. The output of the fourth motor 82 drives the second cutter 83 to rotate at high speed, and the second cutter 83 moves in an arc direction, thereby performing arc-shaped edge cutting on the sheet metal product. When the rotating frame 6 rotates to the required angle, the horizontal rail 72 moves down along the rotating frame 6, causing the first cutter 79 to contact the surface of the sheet metal product. The output of the third motor 78 drives the first cutter 79 to rotate at high speed, and the first protective cover 77 slides horizontally along the horizontal rail 72, allowing the first cutter 79 to perform edge cutting in a straight direction. Thus, by combining arc and straight edge cutting operations, complex edge cutting processing of sheet metal products can be achieved, which is convenient to use and operate.

[0033] Reference Figure 1 and Figure 2 The processing table 1 is provided with multiple positioning holes 11 arranged in a matrix. The sector seat 2 is fixed to the upper surface of the processing table 1 by bolt threads. The processing table 1 is provided with multiple positioning holes 11 arranged in a matrix, so that the sector seat 2 can be conveniently positioned and installed. If the plate metal product is provided with a perforated structure, bolts can also be used for reinforcement and limiting.

[0034] Reference Figure 1 and Figure 2 The sector-shaped base 2 is provided with a sector-shaped groove 21 and an arc-shaped groove 22. The first cutter 79 moves along the arc direction of the arc-shaped groove 22. The high-speed rotating first cutter 79 moves along the arc of the arc-shaped groove 22 along the first protective cover 77, which can realize the arc-shaped cutting edge processing of plate metal products. By providing a sector-shaped groove 21 on the sector-shaped base 2, if there is a protruding structure at the bottom of the plate metal product, it can be set in the sector-shaped groove 21, which facilitates the installation and processing of plate metal products.

[0035] Reference Figure 2 and Figure 3 The positioning mechanism 3 includes two strip plates 31, which are vertically arranged and fixed on the upper surface of the sector seat 2. Two screws 32 are threaded on each strip plate 31, and L-shaped blocks 33 are rotatably connected to the screws 32. When the plate metal product is placed on the upper surface of the sector seat 2, the screws 32 on the locking strip plate 31 are used to clamp the edge of the plate metal product with the L-shaped blocks 33 and the sector seat 2, thereby achieving the limiting and fixing treatment of the plate metal product.

[0036] Reference Figure 1 and Figure 4 A first motor 52 is fixedly installed on the bottom surface of the connecting plate 51. The output end of the first motor 52 is equipped with a first gear 53. A rotating column 541 is rotatably mounted on the connecting plate 51. The rotating column 541 is fixedly sleeved with the rotating frame 6, and a second gear 54 is fixedly mounted on the upper end of the rotating column 541. The first gear 53 and the second gear 54 are meshed and connected. The output end of the first motor 52 drives the first gear 53 to rotate, so that the second gear 54 drives the rotating column 541 to rotate along the connecting plate 51. The rotating frame 6 can be rotated through the rotating column 541. When the piston rod of the hydraulic cylinder 4 extends and retracts, the rotating frame 6 can be lifted and lowered through the connecting plate 51, so that the first cutter 79 can be adjusted in installation height.

[0037] Reference Figure 1 and Figure 4 The rotating frame 6 includes a Y-shaped frame 61 and a concave guide rail 62. The Y-shaped frame 61 and the concave guide rail 62 are fixedly connected. The Y-shaped frame 61 is fixedly sleeved with the rotating column 541. The concave guide rail 62 is slidably connected with the horizontal rail 72 and is fixedly connected with the second protective cover 81. The rotating frame 6, which is composed of the Y-shaped frame 61 and the concave guide rail 62, can drive the second protective cover 81 and the horizontal rail 72 to rotate together. The horizontal rail 72 slides along the concave guide rail 62, thereby adjusting the installation height of the second cutter 83.

[0038] Reference Figure 1 and Figure 4 An electric cylinder 71 is fixedly mounted on the upper surface of the concave guide rail 62. The piston rod of the electric cylinder 71 moves through the concave guide rail 62 and is fixedly connected to the horizontal rail 72. A rack 73 is fixedly mounted on the side of the horizontal rail 72. A second motor 74 is fixedly mounted on the slide block 76. The output end of the second motor 74 is driven by a third gear 75. The third gear 75 meshes with the rack 73. The piston rod of the electric cylinder 71 drives the horizontal rail 72 to slide along the concave guide rail 62, while the second motor 74 drives the third gear 75 to rotate along the rack 73, which can cause the slide block 76 to drive the second cutter 83 to move horizontally along the horizontal rail 72 for processing.

[0039] Working principle: During installation, the sheet metal product is placed on the upper surface of the sector-shaped base 2. By tightening the screw 32 on the locking strip plate 31, the L-shaped block 33 and the sector-shaped base 2 clamp the edge of the sheet metal product, achieving positioning and installation. When arc-shaped edge cutting is required, the piston rod of the hydraulic cylinder 4 retracts, causing the connecting plate 51 to move downwards via the rotating column 541, making the second cutter 83 contact the surface of the sheet metal product. The output end of the first motor 52 drives the first gear 53 to rotate, causing the second gear 54 to drive the rotating column 541 to rotate along the connecting plate 51. The rotating column 541 drives the rotating frame 6 to rotate, while the output end of the fourth motor 82 drives the second cutter 83 to rotate at high speed. As the rotating frame 6 moves in an arc direction, the second cutter... The blade 83 moves along the arc-shaped groove 22 of the fan-shaped seat 2, which can process the arc-shaped edge of the sheet metal product. When the rotating frame 6 rotates to the required angle, the piston rod of the electric cylinder 71 drives the horizontal rail 72 to slide along the concave guide rail 62. The second motor 74 drives the third gear 75 to rotate along the rack 73, which can cause the slide 76 to drive the second cutter 83 to move horizontally along the horizontal rail 72. The horizontal rail 72 moves down along the rotating frame 6, so that the first cutter 79 contacts the surface of the sheet metal product. The output end of the third motor 78 drives the first cutter 79 to rotate at high speed, and the first guard 77 slides horizontally along the horizontal rail 72. The first cutter 79 can be used to process the edge in a straight line. Thus, by combining arc and straight edge cutting operations, complex edge cutting processing of sheet metal products can be realized. It is convenient to use and operate.
