Description

Technical Field

[0001] The invention relates to the technical field of metal processing, in particular to a metal plate grinding and chip removal device. Background Art

[0002] When metal sheets are processed at high temperatures or placed at room temperature, their surfaces will produce scale or rust due to oxidation. Before cold rolling, cold drawing or coating, these oxides need to be cleaned to ensure the quality and effect of the processing.

[0003] There are many methods for removing rust from metal surfaces, including manual treatment, mechanical treatment, and chemical treatment. Mechanical treatment mainly uses sandblasting, shot blasting, electric, and pneumatic tools to remove rust. Commonly used power tools include electric brushes and electric grinding wheels. Electric brushes and pneumatic brushes use the rotation of special round wire brushes to remove rust or oxide scale by impact and friction, especially for surface rust. However, when there are a large number of metal plates and a large area to be rusted, the efficiency of using electric tools for grinding is low, and manual grinding is not stable, resulting in uneven local grinding, resulting in a low yield rate. Secondly, the debris after grinding needs to be cleaned up to avoid affecting subsequent processes. Grinding is more cumbersome, time-consuming and labor-intensive.

[0004] Therefore, it is necessary to develop a metal plate grinding and chip removal equipment to solve the above problems. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 5 The utility model is a metal plate grinding and chip removal device, which includes a frame 1, an upper surface grinding device 2 and a lower surface grinding device 3 installed on the frame 1, and a chip blowing device 4.

[0028] The frame 1 is in a horizontal state and is used to fix the upper surface grinding device 2, the lower surface grinding device 3 and the chip blowing device 4.

[0029] Please see Figures 1 to 2The upper surface grinding device 2 includes a fixed plate 21, a transmission drive part 22 and a transmission passive part 23 installed on the fixed plate 21. The bottom of the fixed plate 21 is fixed to the upper surface of the frame 1, and its top extends vertically upward. The transmission drive part 22 includes a driving motor 221 and an active roller 222. The two ends of the active roller 222 are movably connected to the fixed plate 21. The driving motor 221 drives the active roller 222 to rotate. The transmission passive part 23 is a passive roller of some kind. The active roller 222 and the transmission passive part 23 are surrounded by a conveyor belt 24. The active roller 222 and the transmission passive part 23 are linked by the conveyor belt 24.

[0030] The height of the active roller 222 is greater than that of the passive transmission part 23. The conveyor belt 24 is in an inclined state, with one end thereof extending toward the lower surface grinding device 3. The distance between the upper surface grinding device 2 and the lower surface grinding device 3 gradually becomes smaller.

[0031] Please see Figure 4 A magnetic component 26 is provided in the conveyor belt 24. The magnetic component 26 can absorb the metal sheet located on the surface of the conveyor belt 24. The magnetic component 26 moves synchronously with the conveyor belt 24. In this embodiment, the number of magnetic components 26 changes according to demand. It is embedded in the inner surface of the conveyor belt 24. The magnetic component 26 is an electromagnet. When the upper surface grinding device 2 grinds the metal sheet, the magnetic component 26 is energized to absorb the metal sheet. When the metal sheet moves to the predetermined area, the power is cut off, the magnetic component 26 loses its magnetic force, and the metal sheet is absorbed by the lower surface grinding device 3. The conveyor belt 24 continues to move, and the debris falls into the chip collection bin 10.

[0032] Please see Figure 3 The upper surface grinding device 2 is also provided with a grinding assembly 25, which includes a fixed frame 251 located on both sides of the conveyor belt 24, a movable seat 252 and a driving part 253 installed on the fixed frame 251, and a grinding roller 254 driven by the driving part 253. The bottom of the fixed frame 251 is fixed to the upper surface of the frame 1, and its top extends vertically upward.

The transmission rod 257 is located above the conveyor belt 24 and is parallel to the conveyor belt 24. The grinding roller 254 is sleeved on the transmission rod 257, and the metal sheet can pass between its lower surface and the conveyor belt 24. At the same time, the movable seat 252 can move along the slide rail 256 in the receiving groove 255, so that the distance between the grinding roller 254 and the conveyor belt 24 can be changed.

[0034] The structure of the lower surface grinding device 3 is the same as that of the upper surface grinding device 2 , has a magnetic component 26 and is in a horizontal state. One end of the lower surface grinding device 3 is located above the upper surface grinding device 2 , and the other end extends to above the chip blowing device 4 .

[0035] The lower surface grinding assembly 31 of the lower surface grinding device 3 is located at the bottom thereof, and its structure is the same as that of the grinding assembly 25 .

The blowing plate 432 has a plurality of blowing holes 433. The gas is ejected toward the conveying roller 42 through the blowing holes 433. The number of the blowing plates 432 is a pair, which are respectively located above and below the conveying roller 42.

[0039] When the metal plate grinding and chip removal device of the present invention is in use, the magnetic suction part absorbs the metal plate located on the surface of the conveyor belt 24 and transports it toward the grinding assembly 25, the grinding roller 254 grinds the upper surface of the metal plate, and the distance between the upper surface grinding device 2 and the lower surface grinding device 3 gradually becomes smaller. The metal plate is magnetically attracted to the lower surface grinding device 3, and the lower surface grinding assembly 31 grinds the lower surface of the metal plate. After grinding both sides, it falls onto the conveying roller 42, and the gas is sprayed toward the metal plate located on the conveying roller 42 through the blowing hole 433.
