Description

Technical Field

[0001] This utility model relates to the field of fastener processing technology, specifically to a cutting mechanism for a fastener cutting machine. Background Technology

[0002] Fasteners are a wide range of mechanical parts used for fastening connections. They are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc. They are the most widely used basic mechanical components and typically include bolts, screws, nuts, etc. Bolts are mostly cold-forged, which requires cutting the blank before forming. To ensure the accuracy of forming, the accuracy of the blank volume is very important.

[0003] Currently, when cutting existing fasteners, the operator slowly moves the blank on the cutting table to bring the part to be cut close to the cutting wheel, thereby completing the cutting of the blank. This operation is convenient and quick, but the operator's hands cannot completely fix the blank, which makes it easy to cause the cut to be beveled, resulting in material waste. Moreover, when different lengths need to be cut, the blank needs to be manually adjusted, which greatly increases the workload.

[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0047] Furthermore, the side surfaces of the propulsion wheel 4-5 have a toothed anti-slip structure.

[0048] In this embodiment, the toothed anti-slip structure increases the friction with the bar stock surface, ensuring that the bar stock will not slip when pushed.

[0049] When processing is required, place the bar stock on the pad 4-7, start the drive motor 4-1 and control the two moving frames 4-3 to move synchronously through the adjusting screw 4-2 until the push wheel 4-5 and the clamping wheel 4-6 are in contact with the surface of the bar stock. Then start the second motor 4-4 to control the push wheel 4-5 to rotate and push the bar stock. Stop when the cutting position is reached. Start the third motor 5-1 and drive the swing frame 5-2 through the transmission gear 5-3. This causes the cutting motor 5-4 and the cutting saw blade 5-5 to cut the bar stock by swinging the angle. The cut bar stock falls through the discharge port 6-1 onto the separation plate 6-3 and can be removed. During the cutting process, start the suction collection device 7-4 to generate suction force from the bottom cover 7-5 and the rectangular opening 3 to absorb the waste residue.
