Description

Technical Field

[0001] This utility model belongs to the technical field of diamond saw blade grinding and dressing equipment, specifically, it relates to a vertical multi-station belt grinding and dressing device for diamond saw blades. Background Technology

[0002] Diamond saw blades possess superior cutting characteristics and high wear resistance compared to other materials. Since the 20th century, they have been widely used in various sectors of the aerospace, steel, shipbuilding, cast iron, and manufacturing industries, as well as in major projects such as urban road construction, building construction, and bridge construction. A conventional diamond circular saw blade consists of a metal disc base and an arc-shaped diamond cutting tip welded together. The metal disc base is the main supporting and key component of the circular saw blade, while the cutting tip serves as part of the cutting material. Currently, diamond circular saw blades are typically welded using high-frequency welding, which melts the workpiece at high temperatures to weld the diamond cutting tip and base together. This welding method involves a large welding heat area, slow welding speed, and significant welding deformation, making it difficult to achieve a complete welding assembly of the cutting head and base. Furthermore, the diamond saw blade head is highly prone to detachment during operation, seriously threatening operator safety. However, using high-quality laser welding technology significantly improves the precision of the inner arc surface of the cutter head. Before laser welding diamond saw blades, the contact surfaces of the blade head and base need to be precisely machined.

[0003] Currently, belt abrasive machines are widely used for grinding and dressing tool heads. A belt abrasive machine is a machine that uses a high-speed rotating annular abrasive belt to grind the surface of a workpiece. It is generally operated on a belt grinding machine or a dedicated workbench and can be categorized into benchtop belt abrasive machines, vertical belt abrasive machines, hand-push belt abrasive machines, and dust-collecting belt abrasive machines. The abrasive grains in the belt have an aspect ratio greater than 1.5, uniform grain size distribution, and good abrasive grain contours, resulting in high grinding efficiency. Due to the electrostatic abrasive coating process, the grains are neatly arranged, creating a large chip space between the grains and a small contact area between the grains and the workpiece. This reduces grinding heat generation, resulting in lower residual stress and a shallower surface hardened layer on the workpiece after grinding, thus reducing workpiece deformation and burns. The contact between the belt and the workpiece during abrasion is flexible, providing good running-in and polishing effects, resulting in a smooth surface finish on the processed workpiece. However, existing belt abrasive machines have low grinding efficiency and cannot meet current grinding needs. Therefore, there is a need for a vertical multi-station belt abrasive grinding and dressing device for diamond saw blades that has high grinding efficiency and can meet current grinding and dressing requirements. Utility Model Content

[0004] The purpose of this invention is to provide a vertical multi-station belt grinding and dressing device for diamond saw blades that has high grinding efficiency and meets existing grinding and dressing needs.

[0029] In practical use, this application controls and adjusts the tension of the first tensioning component 5 and the second tensioning component 6 on the front and rear sides of the abrasive belt 4 by rotating the first handwheel 33 and the second handwheel, respectively, so that the tension of the abrasive belt 4 by the first tensioning component 5 and the second tensioning component 6 is moderate. Then, four workers can perform grinding and dressing work on the diamond saw blade at different workstations. When grinding, the worker holds the diamond saw blade close to the abrasive belt 4, and the back of the abrasive belt 4 will contact the corresponding raised arc part 35, thereby achieving a better grinding and dressing work effect.

[0030] The first contact block 7, second contact block 8, third contact block 9, and fourth contact block 10 of this application are all disposed on the table 11.

In practical use, the operator can simultaneously perform grinding and dressing work on the diamond saw blade at all four stations, greatly improving the grinding and dressing efficiency of the diamond saw blade. The first contact block 7, second contact block 8, third contact block 9, and fourth contact block 10 of this application have the same structure, each including a contact block 34 and a raised arc portion 35. The raised arc portions 35 of the first contact block 7 and the second contact block 8 are all located on the front side of the contact block 34 of the first contact block 7 and the second contact block 8, while the raised arc portions 35 of the third contact block 9 and the fourth contact block 10 are all located on the rear side of the contact block 34 of the third contact block 9 and the fourth contact block 10. During grinding and dressing, the raised arc portions 35 on the contact blocks 34 at different locations support the corresponding abrasive belt 4, which is beneficial to the grinding of the diamond saw blade. This not only improves the grinding efficiency of the diamond saw blade but also enhances the grinding and dressing effect of the diamond saw blade. Furthermore, this application has a simple structure and is easy to operate. By utilizing the support effect of the contact block 34 on the abrasive belt 4, four workstations are formed by setting the first contact block 7, the second contact block 8, the third contact block 9 and the fourth contact block.
