Description

Technical Field

[0001] This invention relates to the field of metal cutting technology, specifically to a metal cutting device with a straightening function. Background Technology

[0002] Machining is a crucial part of mechanical manufacturing, widely used in industries such as automobile manufacturing, aerospace, and electronic equipment. It involves using cutting tools to remove excess material from workpieces, thereby obtaining parts with specific shapes, dimensional accuracy, and surface quality. Over its long history, cutting equipment has continuously evolved, from early simple manually operated devices to today's highly automated CNC cutting equipment, significantly improving production efficiency and machining accuracy. Common cutting equipment, such as lathes, are mainly used for machining rotating parts, cutting out the required outer diameters, inner holes, threads, and other surfaces through the relative motion between the cutting tool and the rotating workpiece; milling machines can machine various shapes such as planes, grooves, and steps, relying on the rotation of the cutting tool and the feed motion of the workpiece to achieve cutting; and sawing machines are used to cut raw materials into specific lengths or shapes, commonly including band saws and circular saws, using saw blades or saw discs as cutting tools. These devices play important roles in their respective applications, forming the basic processing force of modern manufacturing.

[0003] However, many current cutting equipment lacks a correction function, which brings a series of thorny problems to actual production. In terms of precision, due to the uneven distribution of internal stress in the workpiece material, tool wear during processing, equipment vibration, and thermal deformation, the processed workpiece often exhibits dimensional deviations and shape errors. Taking the cutting of metal sheets as an example, cutting equipment lacking a correction function struggles to correct the deformation of the sheet caused by heat during cutting in real time, resulting in uneven edges and dimensional inaccuracies that fail to meet the assembly requirements of high-precision products. According to relevant statistics, in the processing of some electronic equipment components with high precision requirements, the scrap rate can reach as high as 15%-20% due to the lack of a correction function. From an efficiency perspective, to compensate for the insufficient precision caused by the lack of a correction function, operators often need to spend a lot of time on manual measurement and adjustment, or perform multiple rework processes. This not only increases the production cycle but also reduces the actual processing efficiency of the equipment. For example, in gear machining, if the cutting equipment cannot automatically calibrate the cutting accuracy, the machining personnel need to frequently stop the machine to measure parameters such as the tooth profile and tooth pitch of the gear. Once a deviation is found, the tool position or cutting parameters must be manually adjusted, which greatly increases the time consumed in the entire machining process and seriously affects the efficiency of mass production. Cost issues cannot be ignored. Increased scrap due to precision defects means wasted raw materials, and rework further consumes energy, manpower, and other resources, significantly increasing production costs. Furthermore, prolonged operation of equipment without correction accelerates wear on key components, shortens the overall lifespan of the equipment, and increases maintenance and replacement costs. Cutting equipment lacking correction capabilities exposes many obvious shortcomings in today's manufacturing industry, which pursues high precision, high efficiency, and low cost. These issues urgently need to be addressed through technological improvements or the introduction of new correction mechanisms to meet the ever-evolving needs of modern manufacturing.
