Description

Technical Field

[0001] The invention relates to the technical field of hardware fittings processing, and more specifically to a cutting device and method for hardware workpieces. Background Art

[0002] Hardware: Traditional hardware products refer to five metals: gold, silver, copper, iron, and tin. They can be made into works of art or metal devices such as knives and swords through artificial processing. Hardware in modern society is more extensive, such as hardware tools, hardware parts, daily hardware, construction hardware, and security products. A product component in the manufacturing process is also called a manufactured part, a workpiece, a courseware, a hardware part, etc. With the development of society, the volume and shape of hardware workpieces are constantly increasing and changing. Conventional cutting machines can no longer meet the processing needs. At the same time, the processing methods of hardware workpieces are also improved accordingly. Previously, only straight cutting of hardware workpieces was required, but now some working conditions require that hardware workpieces may also need to be beveled, etc., and hardware workpieces need to be clamped and fixed during processing, so that the processed hardware workpieces are more accurate. To this end, the inventor proposes a cutting device and method for hardware workpieces, which can fasten hardware workpieces of different shapes and volumes, and can achieve accurate cutting to meet the needs.

[0003] There are some shortcomings in the hardware workpiece cutting devices currently on the market. A Chinese patent (authorization announcement number: CN221474275U) discloses a hardware workpiece cutting fixing device with good fixing effect. The utility model includes a placement plate, a support leg fixedly installed at the bottom of the placement plate, and a processing component arranged on the top surface of the placement plate. The processing component includes a fixing component arranged on the top surface of the placement plate, and a cleaning component is arranged on the inner side of the fixing component. The hardware workpiece cutting fixing device with good fixing effect is composed of a cleaning component as one part. When the two clamping plates move in opposite directions, the fixing rod fixedly installed on the outer wall of the clamping plate is also driven to move, so that the first rack is also moved, so that the gear meshing with the first rack starts to rotate, and the second rack meshing with it starts to move for clamping. However, in the actual hardware tool cutting process, it is often encountered that thin and light hardware workpieces are only fastened with clamps on both sides. During cutting, displacement is prone to occur, which affects the cutting accuracy and even causes cutting failure. Therefore, it is necessary to improve the structure of the clamping of thin and light hardware workpieces. At the same time, with the diversified demand for products, the cutting of hardware workpieces requires not only straight line cutting, but also precise bevel cutting, etc. Summary of the invention
