TECHNICAL FIELD
[0001] The utility model relates to metal target material preparation material processing field especially, it relates to a kind of metal cutting saw blade saw tooth's sticky scrap processing equipment. BACKGROUND
[0002] With the continuous improvement of cutting efficiency and machining surface quality requirements of precision manufacturing, the limitations of traditional sawing process are increasingly highlighted. Under dry cutting conditions, metal chips are easy to form metallurgical bonding with saw teeth due to material activity, forming a stubborn adherent layer. This phenomenon not only changes the actual geometric angle of the tool, causing abnormal fluctuation of cutting force, but also causes the temperature in the cutting zone to rise sharply due to the multiplication of the friction coefficient. The existing scrap processing methods mainly use single mechanical scraping or cooling liquid flushing, the former is difficult to remove micron-sized adhesives, and the latter is easy to cause secondary adhesion of chips and has the risk of cooling medium pollution. More seriously, the local high temperature caused by the accumulation of sticky substances accelerates the tempering softening of the saw blade matrix, and induces the oxidation and embrittlement of the cutting edge, which poses a double threat to the dimensional stability and tool service life of high-precision cutting operations. The intermittent manual cleaning method commonly used in the industry seriously restricts the continuous production process, and the traditional jet dust removal device is difficult to control the temperature rise while ensuring cutting accuracy. Therefore, developing a systematic solution that integrates chip stripping, dynamic cooling and waste recycling functions has become a key breakthrough to improve the processing efficiency of high-activity metal materials. This requires breaking the traditional physical cleaning mindset and building a multi-modal collaborative mechanism to ensure the integrity of the saw blade while achieving real-time cleaning and thermal balance control of the cutting interface.

[0028] The collecting area 103 is used for collecting, precipitating and separating the swarf and the circulating water, and pumping the circulating water into a circulating system.
[0029] Further, in a preferred embodiment of the utility model, the first brush 104 and the second brush 105 are oppositely arranged, which functions to remove part of the swarf and simultaneously reduce the adhesion strength of the swarf.

[0037] It should be noted that the utility model adds a corresponding tool on the basis of a conventional band sawing machine, effectively removes the metal adhesion on the saw blade 201 and reduces the temperature of the saw blade 201.
[0038] The whole workpiece is composed of three parts, namely, a chip removal area 101, a cooling area 102 and a collecting area 103; the workpiece is installed at the rear end of the cut material 203 of the saw blade 201 and moves up and down together with the saw blade 201.

The collection system relies on the funnel structure and the multi-stage filtering device designed based on fluid mechanics to realize the real-time separation and recycling of the cutting waste and the cooling medium, which significantly improves the resource utilization. The whole device realizes the closed-loop control of physical debris removal, dynamic cooling and waste recycling, which not only significantly improves the cleanliness of the sawing interface to ensure the cutting accuracy, but also effectively prolongs the service life of the saw blade 201 by reducing the friction coefficient and thermal load, and solves the contradiction between the medium pollution of the traditional wet cutting and the temperature rise out of control of the dry cutting, providing an efficient and environmentally friendly solution for the precision machining of high-activity metal materials.
