Description

Technical Field

[0001] This utility model belongs to the field of metal bracket processing technology, and specifically relates to a polishing device for metal bracket processing. Background Technology

[0002] Metal brackets are sheet metal products used to provide auxiliary support and load-bearing for connected equipment or items. The processing of metal brackets requires cutting, stamping, grinding and polishing of steel plates.

[0003] Traditional polishing requires manual clamping and loading, which is time-consuming and labor-intensive. Handheld polishing relies on the technician's experience, and the speed and pressure control are unstable, which can easily lead to the thickening of the metal disturbance layer. Repeated polishing and etching are required to eliminate pseudo-structures. At the same time, polishing is prone to over-cutting or omissions, especially for non-precious metals, which are more difficult to control due to differences in hardness. To address this, we propose a polishing device for metal bracket processing. Utility Model Content

[0030] In a specific embodiment of this utility model, the guide rods 404 are symmetrically distributed on both sides of the mounting plate 403, forming a sliding pair with the polishing frame 401. They provide vertical guidance when the first electric cylinder 402 is raised or lowered, enhance longitudinal movement stability, avoid uneven polishing pressure caused by the tilt of the mounting plate 403, ensure surface flatness, reduce the impact of vibration on polishing quality, and prevent the formation of pseudo-structures.

[0031] Specifically, a second electric cylinder 411 is fixedly connected to both sides of the first sliding seat 407, and a cleaning roller 412 adapted to the grinding belt 409 is rotatably connected to the surface of the piston rod of the second electric cylinder 411.

[0032] In a specific embodiment of this utility model, the second electric cylinder 411 drives the cleaning roller 412 to fit against the surface of the grinding belt 409, rotate synchronously with it and scrape off the attached debris, clean the abrasive residue in real time, maintain the cutting ability of the grinding belt 409, avoid the debris from scratching the workpiece surface again, extend the life of the polishing tool and reduce the replacement frequency.

[0035] Specifically, the conveying mechanism 5 includes a connecting frame 501 fixedly connected to the surface of the polishing frame 401. The connecting frame 501 has two horizontally extending second moving rods 502 inside. The surface of the second moving rods 502 is slidably connected to a second moving seat 503.

[0037] Working principle: The operation begins at the feeding inclined plate 6. The electric gripper 505 of the conveying mechanism 5, driven by the fifth electric cylinder 504, grabs the workpiece. The sixth electric cylinder 506 pushes the second moving seat 503 to move horizontally along the second moving rod 502 to above the electric conveyor belt 2, accurately placing the workpiece on the placement tray 3. The electric conveyor belt 2 then feeds the workpiece stepwise into the polishing station inside the protective box 7. The first electric cylinder 402 pushes the mounting plate 403 down along the guide rod 404, causing the grinding belt 409 to contact the workpiece surface. The servo motor 410 drives the grinding roller 4... 08 rotates, driving the grinding belt 409 to move at high speed to generate a grinding effect. The polishing powder cuts the protrusions on the metal surface under mechanical action, while the rolling action causes the metal particles to fill the recessed areas. The fourth electric cylinder 415 controls the first sliding seat 407 to move horizontally and reciprocally. Combined with the intermittent feeding of the electric conveyor belt 2, it achieves uniform polishing at multiple angles. During the process, the cleaning roller 412 driven by the second electric cylinder 411 continuously removes debris from the surface of the grinding belt 409. The third electric cylinder 413 dynamically adjusts the belt tension through the support roller 414 to ensure stability.
