[0022] Embodiments, such as Figure 1

[0023] ​The belt saw blade welding integrated device comprises a first feeding disc 10 and a second feeding disc 20 arranged oppositely; the first feeding disc 10 and the second feeding disc 20 are provided with support seats 11 at the bottom; the support seats 11 are arranged on a support plate 60; the support seats 11 are selectively provided with motors for driving the first feeding disc 10 and / or the second feeding disc 20 to rotate; that is, the support seat 11 at the bottom of the first feeding disc 10 can be provided with a motor for driving the first feeding disc 10 to rotate, thereby facilitating the automatic transmission of the belt saw blade; after the welding of two belt saw blades is completed, the first feeding disc 10 rotates to collect the materials, and the second feeding disc 20 rotates as a driven part; similarly, a motor can also be arranged in the support seat 11 of the second feeding disc 20 to drive the second feeding disc 20 to rotate, and the first feeding disc 10 rotates as a driven part; in an embodiment, motors can also be arranged in the support seats 11 of the first feeding disc 10 and the second feeding disc 20 to drive them to rotate respectively.

[0024] In an embodiment, a cutting device 30 and an end face polishing device 40 are arranged between the first feeding disc 10 and the second feeding disc 20; the cutting device 30 is used for cutting the end faces of two belt saw blades to form new end face notches, which is beneficial to improve the subsequent welding quality; in the production, transportation and storage process of the belt saw blade, the end face may be contaminated by oil stains, rust, dust and other impurities, which will affect the welding quality and cause defects such as pores and inclusions in the weld. By cutting the end face, these impurities can be completely removed, ensuring the cleanliness of the welding area and improving the quality of the welded joint. In the use or processing process of the belt saw blade, the end face may have defects such as wear, cracks and deformation. If these defects are not cut, they will still exist in the weld after welding, becoming a weak link of the welded joint and reducing the strength and reliability of the welded joint. Cutting the end face can remove the defective part, ensuring that the welded part is of good quality. When the belt saw blade is welded, the butt joint accuracy of the two ends needs to be ensured. If the end face is not flat and perpendicular, it will cause the straightness and flatness of the belt saw blade after welding to not meet the requirements, affecting the cutting accuracy and use performance of the belt saw blade. Cutting the end face can make the two end faces of the belt saw blade flat and perpendicular, facilitating accurate butt joint and ensuring the dimensional accuracy after welding.

[0025] The end face polishing device 40 is used for polishing the belt saw blade with the cut end part, removing burrs, and making the end face flat and clean. The flat and clean end face can make the electric arc more stable during welding, and the liquid metal in the welding molten can better wet and spread on the end face, thereby improving the welding fusion quality and making the combination between the weld metal and the base metal of the belt saw blade more firm.

[0026] In an embodiment, the end face polishing device 40 is slidably connected to the support plate 60 to move closer to or farther from the multi-station rotary table 50; in an embodiment, an operation area 62 is formed between the first feeding disc 10 and the second feeding disc 20; the operation area 62 is adjacent to the end face polishing device 40 and the multi-station rotary table 50; by setting the end face polishing device 40 to be movable, the space of the operation area 62 can be expanded after use, facilitating the smooth progress of the subsequent process.

[0027] In an embodiment, a first guide clamping assembly 12 is arranged between the cutting device 30 and the first feeding disc 10; the first guide clamping assembly 12 includes a plurality of guide wheels; the guide wheels can be set to be passively rotated or actively rotated; when at least one of the guide wheels is set to be actively rotated, the band saw blade can be conveyed; the active rotation can be driven by a motor, which is a common technical means in the art.

[0028] In an embodiment, a second guide clamping assembly 21 is arranged between the cutting device 30 and the second feeding disc 20; the second guide clamping assembly 21 includes a plurality of guide wheels; similarly, the guide wheels of the second guide clamping assembly 21 can also be set to be passively rotated or actively rotated.

[0029] In an embodiment, a guide rail 61 is arranged on the support plate 60; the bottom of the end face polishing device 40 is matched with the guide rail 61; a driving assembly for driving the end face polishing device 40 to move is arranged on the support plate 60; the automatic displacement control of the end face polishing device 40 is realized by the driving assembly; in an embodiment, the driving assembly is a pneumatic cylinder driving assembly or a lead screw driving assembly.

[0030] In an embodiment, a multi-station rotary table 50 is arranged on the opposite side of the end face polishing device 40; a welding device 51, a surface polishing device 52, a gear grinding device 53, a polishing device 54, and a sandblasting device 55 are sequentially arranged on the multi-station rotary table 50 in a clockwise or counterclockwise direction; the welding device 51, the surface polishing device 52, the gear grinding device 53, the polishing device 54, and the sandblasting device 55 are all prior art in the art, and thus their specific structures will not be described here; by sequentially installing the processing devices on the multi-station rotary table 50, the final welding quality of the band saw blade can be effectively improved.

[0031] In an embodiment, the multi-station rotary table 50 includes a bottom plate 501; a plurality of rotating seats 502 are arranged on the bottom plate 501 at intervals; a plurality of rollers 503 are arranged on the rotating seats 502 at intervals in the circumferential direction; and a rotating driving device for controlling the rotation of the rotating seats 502 is connected to the rotating seats 502.

[0032] The role of surface polishing: through polishing, the surface quality can be improved, and welding defects can be removed. During the welding process, defects such as pores, slag inclusion, spatter, etc. may appear on the surface of the weld. Through polishing, these defects can be removed, making the weld surface smoother and more uniform, and improving the overall appearance quality of the band saw blade. After welding is completed, the weld will usually be higher than the surface of the band saw blade, forming a weld excess. The existence of excess will affect the stability and cutting accuracy of the band saw blade during cutting. Through polishing, the weld excess can be removed, making the weld flush with the surface of the band saw blade, ensuring the stability of the band saw blade during cutting. The fatigue strength of the welded joint is usually lower than that of the base material of the band saw blade due to the existence of welding residual stress and micro defects. Surface polishing can remove micro cracks and stress concentration points on the surface of the weld, reduce the roughness of the weld surface, and thus improve the fatigue strength of the welded joint and prolong the service life of the band saw blade.

[0033] The role of gear grinding: restore tooth profile accuracy. The welding process may cause the saw teeth of the band saw blade to deform, wear or reduce accuracy. The gear grinding process can accurately restore the original shape and dimensional accuracy of the saw teeth, ensuring that the band saw blade can accurately cut into the material during cutting, improving cutting accuracy. Sharp and accurate saw teeth can cut into the material more smoothly, reducing resistance and friction during cutting, thereby improving cutting efficiency and reducing cutting energy consumption and cost. Through gear grinding, the rake angle, relief angle, wedge angle and other angle parameters of the saw teeth can be optimized, making the cutting edge of the saw teeth sharper and enhancing the cutting ability of the band saw blade for different materials, adapting to the cutting of materials of various hardness and thickness.

[0034] The role of polishing: polishing can remove fine scratches, grinding marks, burrs and other imperfections left on the surface of the band saw blade after gear grinding, making the surface smoother and more delicate, and achieving a high degree of finish. If the sandblasting process is performed first, these fine imperfections may be further embedded in the surface or become more pronounced due to the impact of sandblasting, affecting the final surface quality of the band saw blade. The smooth surface after polishing provides a more uniform basis for sandblasting, allowing abrasive particles to impact the surface of the band saw blade more uniformly during sandblasting, thereby achieving a more consistent and attractive surface roughness and texture. If the surface is uneven or has many imperfections, the local roughness may not be uniform and the surface quality may not be consistent after sandblasting.

[0035] The role of surface sandblasting: increase surface roughness. Through sandblasting, the surface of the band saw blade forms a certain roughness, which helps to improve the adhesion of the coating to the surface of the band saw blade and enhance the protective effect of the coating. For example, when hard chromium plating or wear-resistant coating is applied, the coating can better adhere to the band saw blade; the surface compressive stress generated by sandblasting can refine the grains on the surface of the band saw blade, thereby improving the fatigue strength of the band saw blade and reducing the likelihood of fatigue cracks and fractures during repeated cutting. Further, it is also used to enhance the appearance consistency with the non-welded area.

[0036] Working principle: before use, first install two band saw blades on the first feeding disc 10 and the second feeding disc 20 respectively, pass the band saw blade on the first feeding disc 10 through the first guide clamping assembly 12, cut off the end part by using the cutting device 30, and then polish by using the end face polishing device 40; pass the band saw blade on the second feeding disc 20 through the second guide clamping assembly 21, cut off the end part by using the cutting device 30, and then polish by using the end face polishing device 40; the end face polishing device 40 can be away from the multi-station rotary table 50 after use, so as to leave more space for the operation area 62; further, place the two polished band saw blades in the welding device 51 for welding, after welding, rotate the rotary seat 502, so that the surface polishing device 52 is rotated to the position opposite to the operation area 62, and the upper and lower surfaces of the welding part are polished; further, rotate the rotary seat 502, so that the gear grinding device 53 is rotated to the position opposite to the operation area 62, and the saw teeth of the welding part are ground and trimmed; further, rotate the rotary seat 502, so that the polishing device 54 is rotated to the position opposite to the operation area 62, and the surface of the welding part is polished; further, rotate the rotary seat 502, so that the sand blasting device 55 is rotated to the position opposite to the operation area 62, and the surface of the welding part is sandblasted, and the whole band saw blade welding process is completed.

[0037] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent transformation or direct or indirect application in the related technical field by using the content of the present application is also included in the patent protection range of the present application.
