Description

Technical Field

[0001] This utility model relates to the field of automotive steel sheet shearing technology, and in particular to a shearing machine that facilitates the positioning of sheet metal. Background Technology

[0002] The automobile is a significant symbol of modern civilization, transforming human living conditions, lifestyles, and work methods. It is also a pillar industry of the national economy, boosting GDP, promoting related economic development, and providing numerous job opportunities. During automobile manufacturing, the car body is formed from sheet metal. Before processing these body panels, the sheet metal must be pre-cut to the required size to fit into the forming equipment for further processing. Traditional shearing machines have some drawbacks. During shearing, the cutting line is marked on the steel plate using a professional ruler. The steel plate is then pushed to the blade position, and the shearing line is aligned with the blade position by the operator's eye. However, this shearing method requires a high level of skill from the operator, as it relies on visual alignment, which can easily lead to deviations. This results in the cut steel plate not meeting the specified dimensions, reducing the quality of the finished product, and making it difficult to accurately position the cutting line and the blade.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figures 1-5 As shown, a shearing machine for easy plate positioning includes a support frame 1, a hydraulic cylinder 5, and a blade 8. An operating table 2 is fixedly connected to the inner side of the support frame 1. A positioning auxiliary mechanism 7 is provided at one end of the support frame 1. The positioning auxiliary mechanism 7 includes a fixed frame 71 fixedly connected to one end of the support frame 1. A threaded shaft 72 is movably connected to the inner side of the fixed frame 71. A control ring 73 is threadedly connected to the outer side of the threaded shaft 72 near the lower side of the fixed frame 71. A connecting rod 74 is fixedly connected to the front end of the control ring 73. A positioning frame 75 is fixedly connected to the front end of the connecting rod 74. An indicator needle 76 is fixedly connected to the inner wall of the positioning frame 75. A docking rod 77 is fixedly connected to the front end of the positioning frame 75. A sliding frame 78 is fixedly connected to the front end of the docking rod 77. A support rod 79 is slidably connected to the inner side of the sliding frame 78.

[0015] In this embodiment, a limit ring 710 is fixedly connected to the outer side of the threaded shaft 72 near the fixed frame 71 and the control ring 73. A bearing 711 is movably installed on the outer side of the threaded shaft 72 near the lower side of the control ring 73. A knob 712 is fixedly connected to the upper end of the control ring 73. A baffle 713 is fixedly connected to the upper end of the support rod 79. The connecting rod 74 and the docking rod 77 are both Z-shaped. The positioning frame 75 is located directly below the tool 8. The indicator needle 76 corresponds to the tool 8. The inner wall width of the positioning frame 75 is greater than the thickness of the tool 8. The lower end of the support rod 79 is fixedly connected to the upper end of the operating table 2. The lower end of the bearing 711 is fixedly connected to the upper end of the operating table 2 near the rear side of the support rod 79.

[0016] Specifically, the worker first marks the cutting position on the steel plate, then places the steel plate on the operating table 2. Next, they rotate knob 712, causing the threaded shaft 72 to rotate. This causes the control ring 73 to move upwards along the threaded shaft 72, and via the connecting rod 74, it moves the positioning frame 75 upwards. The positioning frame 75 then moves upwards along the support rod 79 via the connecting rod 77, allowing the positioning frame 75 to move smoothly upwards. The steel plate is then pushed below the positioning frame 75, and knob 712 is rotated in the opposite direction, causing the positioning frame 75 to move downwards and onto the steel plate. By pushing the steel plate to move it and positioning its shearing position within the positioning frame 75, and setting the indicator needle 76 to point at the shearing position, the shearing position of the steel plate corresponds to the cutter 8. This accurately positions the shearing position of the steel plate below the cutter 8. By placing the steel plate below the positioning frame 75 and then pushing it to move it to the inside of the positioning frame 75, the indicator needle 76 points to the shearing position of the steel plate. This achieves the goal of aligning the shearing position of the steel plate with the cutter 8, thereby accurately positioning the shearing position of the steel plate below the cutter 8 and improving the accuracy of the worker's steel plate shearing.

[0017] In this embodiment, a support leg 3 is fixedly connected to the lower end of the operating table 2, and a mounting bracket 4 is fixedly connected to the upper end of the support frame 1. A hydraulic cylinder 5 is installed inside the mounting bracket 4, and a mounting seat 6 is installed at the telescopic end of the lower end of the hydraulic cylinder 5. A cutting tool 8 is installed at the lower end of the mounting seat 6, and a slide 9 is fixedly connected to the rear end of the mounting seat 6. A slide rail 10 is slidably connected to the inner side of the slide 9, and the rear end of the slide rail 10 is fixedly connected to the inner wall of the support frame 1.

[0018] Specifically, starting the hydraulic cylinder 5 causes the hydraulic cylinder 5 to push the mounting base 6 downward, and the mounting base 6 causes the slide 9 to move downward along the slide rail 10. This allows the mounting base 6 to move the cutter 8 downward smoothly, and the cutter 8 to be inserted into the inner side of the positioning frame 75. This allows the cutter 8 to cut the steel plate at the shearing position, thereby achieving the shearing of the steel plate at the designated position.

[0019] Working principle: In operation, the worker first marks the cutting position on the steel plate, then places the steel plate on the operating table 2. Next, they rotate knob 712, causing the threaded shaft 72 to rotate. This causes the control ring 73 to move upwards along the threaded shaft 72, and via the connecting rod 74, it moves the positioning frame 75 upwards. The positioning frame 75 then moves upwards along the support rod 79 via the connecting rod 77, allowing the positioning frame 75 to move smoothly upwards. The steel plate is then pushed below the positioning frame 75, and knob 712 is rotated in the opposite direction, causing the positioning frame 75 to move downwards and onto the steel plate. The steel plate is then pushed again, positioning the cutting position within the positioning frame 75, and the indicator needle 76 points to the cutting position, thus aligning the cutting position of the steel plate with the cutter 8. Then, the cutting position of the steel plate is accurately positioned below the cutter 8. Then, the hydraulic cylinder 5 is activated, which pushes the mounting base 6 downward and causes the mounting base 6 to drive the slide 9 downward along the slide rail 10. This allows the mounting base 6 to drive the cutter 8 downward smoothly and insert the cutter 8 into the inner side of the positioning frame 75. The cutter 8 can then cut the steel plate at the designated cutting position, thereby achieving the purpose of cutting the steel plate at the designated position. By placing the steel plate below the positioning frame 75 and then pushing the steel plate to move it and moving the cutting position of the steel plate to the inner side of the positioning frame 75, the indicator needle 76 points to the cutting position of the steel plate. This makes it easy to align the cutting position of the steel plate with the cutter 8, thereby accurately positioning the cutting position of the steel plate below the cutter 8 and improving the accuracy of the worker cutting the steel plate.
