Description

Technical Field

[0001] The invention relates to a novel high-speed aluminum material sawing band saw. Background Art

[0002] The band saw is the main equipment used for cutting long aluminum materials. In the prior art, the band saw generates high temperature when cutting the workpiece, so the cutting position of the band saw needs to be cooled by coolant.

[0003] In the prior art, this cooling system operates independently, and sprays coolant at the contact point between the band saw and the workpiece. However, this spraying position is on the surface of the workpiece, and needs to flow into the sawing position through the gap of the cut workpiece for cooling. This cooling method is sufficient for the workpiece, but slightly lacks the cooling effect on the band saw. The reason is that the band saw passes through the workpiece continuously, and the contact time per unit area with the workpiece is short. Therefore, when the band saw runs at a high speed, the heat generated by the band saw is still large, which is easy to cause fatigue damage and eventually lead to breakage.

[0004] Based on the above problems, we designed a new type of aluminum high-speed cutting band saw that upgrades the existing independent cooling system and is specifically designed for guiding and dissipating heat for the band saw. Summary of the invention

[0072] It has two functions. The first is to clean the band saw 59. The second is to lubricate the band saw 59 and the cooling guide wheel 806 to reduce the wear between the two.

[0073] The limit cover 809 can rotate by itself, so the limit covers 809 on the front and rear sides can form limits above the band saw 58.

[0074] See also Fig.14 and Fig.18As shown, the elastic pressure wheel assembly 9 includes a wheel seat 901, in which a first upper pressure wheel 902 is rotatably arranged, and an outer wall of the first upper pressure wheel 902 is processed with a first annular groove 903 for positioning the band saw 59, and the groove width of the first annular groove 903 gradually decreases toward the axial direction of the first upper pressure wheel 902; a connecting bracket 904 is arranged above the wheel seat 901, and the connecting bracket 904 is connected to the outer shell structure 701 and is located above the slot 707, and a guide rod 905 is assembled from the top of the connecting bracket 904 downward, and the lower end of the guide rod 905 is threadedly fixed to the wheel seat 901, and the upper end of the guide rod 905 The limit is located at the top of the connecting bracket 904, and a spring 906 is sleeved on the guide rod 905. The spring 906 acts between the connecting bracket 904 and the wheel seat 901. A hose hole corresponding to the first annular groove 903 is processed on the top of the wheel seat 901, and a drainage hose 907 is inserted through the hose hole. The end of the drainage hose 907 away from the wheel seat 901 passes through the water diversion groove 702, and the height of the end of the drainage hose 907 inserted into the water diversion groove 702 is the same as the upper end of the wheel axle 801, so that the coolant in the water diversion groove 702 flows out from the wheel axle 801 and the drainage hose 907 at the same time.

[0075] In the above technical solution, the band saw 59 can be positioned through the first annular groove 903 ; at the same time, the coolant can also flow out from the drainage hose 907 and act on the first annular groove 903 to cool the band saw 59 and the first upper pressure wheel 902 .

[0076] See also Fig.14 , Fig.19 and Fig. 20As shown, the scraper device 10 includes two front and rear scrapers 1010, and at least two movable rods 1011 are installed at the outer end surface of each scraper 1010. A sleeve 1012 is sleeved on the movable rod 1011, and the end of the sleeve 1012 is fixed to the inner wall of the outer shell structure 701. A first spring 1222 is installed inside the sleeve 1012. A slider 1013 is provided at one end of the movable rod 1011, and the slider 1013 fits the inner wall of the sleeve 1012. The other end of the movable rod 1011 is fixed to the inner wall of the sleeve 1012. The scraper 1011 is fixed, and a limiting cap 1014 is screwed into the opening of the sleeve 1012, and the limiting cap 1014 limits the sliding out of the slider 1013; the band saw 59 passes through the scrapers 1010 on both sides and cooperates with the scrapers 1010 with a clearance of 0.2mm to 0.4mm; a conical passive hole 1015 is provided on the top of the scraper 1010; a sliding hole 1016 corresponding to the passive hole 1015 is provided at the bottom of the water diversion trough 702, and the sliding hole 1016 A sliding rod 1017 is installed inside, and the upper end of the sliding rod 1017 is threadedly connected to a water inlet cover 1018, and the upper end of the water inlet cover 1018 is a concave spherical plate 1019, and a water inlet hole 1020 is arranged on the plate surface of the spherical plate 1019; a first limit plate 1021 made of elastic rubber material is clamped on the outer wall of the sliding rod 1017, and the first limit plate 1021 is limited to the inner bottom of the through bin 705 and forms a closure for the sliding hole 1016, and a second spring 1021 is sleeved on the sliding rod 1017. 22. The second spring 1022 acts between the water inlet cover 1018 and the water diversion trough 702. The lower end of the sliding rod 1017 is processed to form a conical separation cone 1023. A plurality of first liquid outlet holes 1024 are distributed on the outer cone surface of the separation cone 1023. The water inlet cover 1018 corresponds to the inlet pipe 704. When the water inlet flow rate increases, the water flow impacts the water inlet cover 1018, causing the sliding rod 1017 to move downward. After the sliding rod 1017 moves downward, the separation cone 1023 squeezes open the scrapers 1010 on both sides.

[0077] In the above technical solution, the band saw 59 passes through the scrapers 1010 on both sides and maintains a small distance between the band saw 59 and the scrapers 1010 on both sides. When the band saw 59 passes, large chips are scraped off by the scrapers 1010.

[0078] During the operation of the band saw 59, a small flow of coolant is maintained. At this time, the separation cone 1023 does not descend, and part of the coolant enters through the water inlet cover 1018 and flows out from the first liquid outlet 1024. The outflowing coolant acts on the scraper 1010, so that the attached chips are washed off.

[0079] When a harsh sound occurs during the operation of the band saw, it means that some chips are stuck between the band saw 59 and the scraper 1010. At this time, the input of coolant is increased to increase the speed of the coolant entering the water diversion tank 702, impacting the water inlet cover 1018, causing the separation cone 1023 to fall and squeeze the scrapers 1010 on both sides. At this time, the first liquid outlet 1024 is located between the two scrapers 1010. At the same time, the amount of liquid discharged increases to flush the chips between the scraper 1010 and the band saw 59.

[0080] It should be noted that the height of the band saw 59 is lower than the height of the lower end surface of the separation cone 1023 after it falls.

[0081] When a small flow rate is maintained for the liquid entering the cold zone, the coolant overflows from the upper end of the water inlet cover 1018 into the water distribution tank 702 and is then transported to the first upper pressure wheel and the cooling guide wheel 806 .

[0082] The vertical height of the scraper 1010 is more than twice the width of the band saw 59, so that when the band saw 59 passes through the two scrapers 1010, it is completely located on the inner side of the slide plate 1010, ensuring that most of the attached chips can be removed.
