Description

Technical Field

[0001] The invention relates to the field of glass cutting wheel processing, and in particular to a device and method for processing inner holes of a glass cutting wheel. Background Art

[0002] Glass production and glass cutting are inseparable. Whether it is raw glass production or deep-processed glass production, to achieve the required size and shape of glass pieces, optimized cutting must be performed, especially for raw glass production, which must be cut, otherwise the entire glass ribbon cannot be stacked and packaged. The most common wheel cutting method currently is to use the force of rolling friction to roll and carve scratches on the surface of the glass piece along the direction to be cut, and then apply mechanical external force along the scratches to achieve glass fragmentation.

[0003] Wheel cutting is a process in which a cutter wheel, a cutter shaft, and a cutter frame are formed together and installed on a cutting machine. For example, the patent document with announcement number CN221344404U discloses a glass cutting head mechanism and a glass cutting system. According to the principle of wheel cutting, the cutter wheel frame rolls on the surface of the glass plate to make cuts. The thinner, straighter and smoother the cuts are, the easier it is to split. This requires that the cutter wheel rolls smoothly without obstruction, which means that the quality of the inner hole of the cutter wheel is relatively high. However, because the inner hole of the cutter wheel is small in size, and the cutter wheel is usually made of super-hard materials such as cemented carbide, the difficulty of processing the inner hole is greatly increased. The existing inner hole processing of the cutter wheel cannot realize the automatic continuous clamping-grinding-unloading and batch unloading, and the processing efficiency is low, and the processing quality cannot be guaranteed.

[0012] As an optimized technical solution, the reversing discharge port includes a transition section and a reversing section. The transition section is connected between the feeding channel and the reversing section. The inner cavity of the transition section gradually transitions from matching the inner cavity of the feeding channel to matching the inner cavity of the reversing section.

[0038] The embodiment of the present invention further discloses a method for processing the inner hole of a glass cutting wheel, which uses the inner hole processing device of the glass cutting wheel, and comprises the following steps:

When the cutter wheel blank 7 moves to the storage area 32, the clamping mechanism 2 is released to leave the cutter wheel blank 7 in the storage area 32.

[0042] Step 4: the clamping mechanism 2 returns to the initial position to clamp the next cutter wheel blank 7, and then moves the next cutter wheel blank 7 from the processing area 31 to the storage area 32 for grinding. The processed cutter wheel blank 7 continues to stay in the storage area 32;

[0043] Step 5: Figure 5 As shown, when the storage area 32 is full of processed cutter wheel blanks 7, when the clamping mechanism 2 moves to the storage area 32 with the next cutter wheel blank 7, the second chuck 5 opens and moves outward until there is a gap between it and the end of the reaming rod 3, and the processed cutter wheel blanks 7 in the storage area 32 are pushed into the cutter wheel storage box 6 in sequence;

[0044] Step six, the second chuck 5 returns to clamp the reaming rod 3, the clamping mechanism 2 releases the clamped cutter wheel blank 7, and then repeats the automatic clamping, grinding and automatic unloading process from step four to step five.
