Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a grinding and chip removal device for the edges of metal sheets. Background Technology

[0002] In the field of sheet metal processing, after cutting, metal sheets will have burrs, flash, oxide scale, or rough and uneven surface defects on their sides. If these defects are not effectively treated, they may lead to assembly errors, surface scratches, or corrosion risks. Therefore, after cutting, metal sheets need to have their sides and corners polished.

[0003] When grinding the edges of metal sheets, workers typically need to manually push the sheet to bring it into contact with a rotating grinding wheel or belt. This grinding process is inefficient and poses a certain risk of hand injury to workers. Currently, some equipment can automatically grind the edges and corners of metal sheets. For example, Chinese patent application CN202322064057.5 discloses a steel plate grinding machine. It includes a support plate with two fixed plates fixedly mounted near the center of the top. A second grinding roller is rotatably connected to the adjacent sides of the fixed plates near the bottom. Lifting ports are opened near the top of the adjacent sides of the fixed plates, and a lead screw is rotatably connected to the inner cavity of each lifting port. A lifting block is threadedly connected to the outer edge of each lead screw, and the outer edge of each lifting block is slidably connected to the inner side of the adjacent lifting port. An mounting plate is fixedly installed on the adjacent side of each lifting block. This steel plate grinding machine allows for simultaneous grinding of the top and bottom of the steel sheet, saving time and labor, reducing the workload of workers, and improving the efficiency of the equipment.

[0004] Existing grinding equipment typically only grinds sheets of a single size and shape, resulting in poor adaptability. Metal sheets come in a variety of shapes (round, oval, or polygonal), and different shapes require different grinding paths and clamping methods. Most existing equipment is fixed in structure, only suitable for sheets of specific specifications or shapes. Changing to different shapes requires readjusting the clamping position or replacing grinding tools, which is time-consuming and labor-intensive, failing to meet the diverse, small-batch production needs of modern manufacturing.

Detailed Implementation

[0026] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0027] Please refer to Figures 1 to 4 The present invention relates to a metal sheet edge grinding and chip removal device, comprising a worktable 100, a rotary clamping assembly, and a chip removal and grinding assembly.

[0028] The workbench 100 is a rectangular plate, which is supported on the ground by support legs. The rotary clamping assembly includes a clamping base plate 200, a rotary drive mechanism, and a lifting and pressing mechanism. The clamping base plate 200 is rotatably mounted on the workbench 100. The rotary drive mechanism is connected to the clamping base plate 200. Specifically, a rotating shaft 202 is connected to the bottom of the clamping base plate 200. A vertically mounted rotating bushing 101 is fixed on the workbench 100. The rotating shaft 202 is rotatably mounted in the rotating bushing 101 through a first bearing 203.

A second bearing 400 is provided at the lower end of the telescopic shaft of the clamping cylinder 300. The inner ring of the second bearing 400 is fixedly sleeved on the lower end of the telescopic shaft of the clamping cylinder 300. The clamping plate 401 is fixedly connected to the bottom of the outer ring of the second bearing 400. The clamping plate 401 and the outer ring of the second bearing 400 can be connected by welding. By using bearing components to connect the telescopic shaft and the pressure plate 401, the pressure plate 401 can rise and fall with the telescopic shaft of the pressure cylinder 300, and can rotate relative to the telescopic shaft of the pressure cylinder 300. Furthermore, the bearing components are standard parts, which can reduce manufacturing costs.

[0030] After the plate 800 to be processed is clamped by the clamping cylinder 300, the rotary drive motor 204 can still drive the plate 800 to rotate. This metal plate edge grinding and chip removal equipment uses the clamping cylinder 300 and the rotatable clamping plate 401 as a clamping structure.

The output shaft of the grinding drive motor 700 has a drive pulley 701, and the grinding belt 500 is fitted onto the drive pulley 701 and the two driven abrasive belt cylinders 604. Specifically, the sliding base plate 600 is provided with a fixed baffle 601, the elastic element 603 is a helical spring, and the two ends of the elastic element 603 respectively abut against the sliding bracket 602 and the fixed baffle 601.

[0033] In a preferred embodiment, both the lower surface of the clamping plate 401 and the upper surface of the clamping base plate 200 are provided with a friction pad 201 made of rubber. The friction pad 201 can improve the frictional clamping force between the two on the plate to be processed 800 and prevent the plate to be processed 800 from sliding during the grinding process.

[0034] In a preferred embodiment, a motor mounting plate 102 is provided below the workbench 100, and the rotary drive motor 204 is fixed to the motor mounting plate 102. The motor mounting plate 102 is connected to the workbench 100 through multiple fixing rods.

[0035] In a preferred embodiment, the metal sheet edge grinding and chip removal equipment further includes an air blowing chip removal component.

A strip-shaped air nozzle 901 is provided on the air blowing pipe 900. The air nozzle 901 is inclined downward so that the air blowing range of the air nozzle 901 covers the grinding belt between the two driven sanding belt cylinders. The air nozzle 901 is used to blow off the metal chips ground by the grinding belt and prevent the metal chips from adhering to the sheet.

[0036] The working process of this utility model's metal sheet edge grinding and chip removal device is as follows: The sheet material 800 to be processed is placed on the clamping base plate 200 (aligning the center of the sheet material 800 with the center of the clamping base plate 200); the clamping cylinder 300 drives the clamping plate 401 to clamp and fix the sheet material 800 to be processed; the grinding drive motor 700 is started, which drives the drive pulley 701 to rotate, causing the grinding belt 500 to rotate; the sliding drive cylinder 104 drives the entire sliding base plate 600 towards the sheet material to be processed. The plate 800 slides, causing the rotating abrasive belt 500 to contact the side of the plate 800 to be processed, thereby grinding the edge of the plate 800; the rotary drive mechanism (rotary drive motor 204) drives the plate 800 to be processed to rotate, so that multiple sides and corners of the plate 800 are in contact with the abrasive belt 500, thereby realizing automatic grinding of the plate edge; during the grinding process of the plate edge, the air nozzle 901 on the air pipe 900 blows air to blow off the metal debris ground by the abrasive belt.

[0037] In the above process, the elastic element 603 can ensure that the sanding belt 500 is taut and can fit tightly against the edge of the plate. At the same time, the flexible structure of the sanding belt 500 can undergo adaptive deformation when the plate rotates. The sanding belt 500 combined with the elastic element 603 can adapt to the sanding needs of various shapes (round, elliptical, polygonal, etc.), significantly improving the versatility of the equipment.
