Description

Technical Field

[0001] The utility model relates to the technical field of stone processing, in particular to a coil opener for a diamond frame saw blade. Background Technique

[0002] A diamond band saw is a linear and curve cutting tool made of superhard materials. It uses diamond as the sawtooth material, with extremely high hardness and wear resistance. The basic shape of the diamond band saw is similar to that of a woodworking band saw for sawing wood boards, but the main difference is that it uses diamond particles consolidated on one side of the steel strip to form diamond sawteeth. The diamond particles are consolidated on the annular steel strip through the electrocrystallization of the metal. The two ends of the steel strip are welded together to form a closed loop, so it is called a band saw. Due to its unique combination of flexibility and rigidity, it can rotate and bend like a belt while keeping the sawteeth firm, achieving precise cutting of various materials.

[0003] The technical solution disclosed in the Chinese patent with the authorization announcement number CN106219279A unwinds the steel strip coil through a rocker arm, with simple and convenient operation. The rollers on the upper baffle and the lower baffle perform outer radial limiting on the steel strip coil, the rollers on the positioning block perform inner radial limiting on the steel strip coil, and the long plate group performs axial limiting on the steel strip coil, which can prevent the coil from spreading and also prevent the abnormal displacement of the steel strip coil. At the same time, the upper frame, the lower frame, the baffle and the clamping frame are used for safety protection, effectively avoiding potential safety hazards; on the other hand, it also simplifies the system structure and reduces the manufacturing cost of the device.

[0004] However, this device still has deficiencies: when installing the steel coil, it needs to be welded and fixed, and the entire device also needs to rely on a lifting device to assist in lifting the height of the steel coil, with very troublesome operation. Content of the Utility Model
