Description

Technical Field

[0001] The invention belongs to the technical field of aluminum profile processing equipment, and in particular relates to a cutting device for aluminum profile processing. Background Art

[0002] Aluminum alloy profiles are the most widely used type of non-ferrous metal structural materials in industry. Among them, cutting of aluminum alloy tubes is a common operation in metal processing, which is used to meet the processing requirements of different sizes and shapes. There are various methods for cutting aluminum alloy tubes, and the choice depends on the thickness, diameter, cutting accuracy requirements, work efficiency and cost considerations of the tube. The goal of aluminum alloy tube cutting is to accurately divide the aluminum alloy tube according to the predetermined size, angle or shape to meet the needs of subsequent processing or assembly. There are many commonly used aluminum alloy tube cutting methods, and the most common one is mechanical cutting, which includes circular saw cutting; band saw cutting, etc.

[0003] Among them, circular saw cutting still has the following shortcomings in the process of cutting aluminum alloy tubes: in the existing aluminum alloy tube cutting process, most of them at least simply clamp and fix the aluminum alloy tube, which leads to the aluminum alloy tube being bent during the cutting process if the aluminum alloy tube is thin, resulting in the cutting surface being tilted, which easily leads to uneven end faces after cutting, affecting the subsequent processing and use of the aluminum alloy tube; if the diameter of the aluminum alloy tube is large, the traditional full penetration cutting method will cause the cutting blade to cut too deep, so that its cutting force will also increase, and the pressure on the tool will also increase, which will cause greater wear on the main cutting surface and cutting edge of the tool, and when the cutting depth increases, the cutting force will also increase, which will cause friction in the cutting area, thereby causing the temperature of the tool and the workpiece surface to rise, thereby affecting the cutting performance and cutting surface quality.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The present invention provides a guide roller device. When cutting an aluminum alloy tube, a worker inserts the aluminum alloy tube between a fixed guide roller and a movable guide roller of the guide roller device on one side, passes the tube through the through hole, and then passes the tube out from between the fixed guide roller and the movable guide roller of the guide roller device on the other side.

[0014] 3. The present invention arranges a hydraulic rod, a first gear, a clamping block, and a second motor. After the aluminum alloy tube is fixed, if the aluminum alloy tube is a thin aluminum alloy tube, the hydraulic rod is directly controlled to retract, so that the cutting blade can move downward to directly penetrate and cut the thin aluminum alloy tube; if the aluminum alloy tube is a large or medium-sized thick aluminum alloy tube, after it is adjusted and fixed in the above manner, the hydraulic rod is similarly controlled to retract, so that the cutting blade moves downward to cut the aluminum alloy tube. At this time, the cutting blade only moves downward to a degree slightly larger than the wall thickness of the aluminum alloy tube for cutting, and the second motor is controlled to work at the same time, by driving the first gear meshing with the second gear to rotate, and the clamping block is fixedly installed on the first gear, and the aluminum alloy tube is clamped and fixed, so that the first gear can drive the aluminum alloy tube to rotate, and cooperate with the cutting action of the cutting blade, so that the aluminum alloy tube can rotate during the cutting process, so as to achieve uniform cutting of the outer circle of the aluminum alloy tube and improve the cutting quality; at the same time, the cutting depth of the cutter is effectively reduced, and the service life of the cutter is improved.

[0026] Among them, the tensioning device includes a third fixed plate 29 fixedly connected to the side plate 18, a third screw rod 30 is threadedly connected to the middle part of the third fixed plate 29, one end of the third screw rod 30 is rotatably connected to the second sliding block 31 slidably sleeved with the side plate 18, one end of the second sliding block 31 is rotatably connected to the tensioning wheel 32, and the output shaft end of the third motor 26 is movably sleeved with a transmission belt 33, and the transmission belt 33 is sequentially transmission-connected with the second transmission wheel 28, the first transmission wheel 25, the tensioning wheel 32, and the guide wheel 27. When cutting the aluminum alloy pipe, by starting the third motor 26, the fixed guide roller 20 and the movable guide roller 24 can be driven to rotate, and the left and right position of the aluminum alloy pipe can be controlled by controlling the rotation direction of the third motor 26, so that the staff can adjust the cutting position of the aluminum alloy pipe and cut a certain length according to needs.

[0030] When cutting the aluminum alloy tube, the staff inserts the aluminum alloy tube between the fixed guide roller 20 and the movable guide roller 24 of the guide roller device 8 on one side, passes through the through hole 12, and then passes out from between the fixed guide roller 20 and the movable guide roller 24 of the guide roller device 8 on the other side.

[0032] After the aluminum alloy tube is fixed, if the aluminum alloy tube is a thin aluminum alloy tube, the hydraulic rod 7 is directly controlled to retract, so that the cutting blade 6 can move downward to directly penetrate and cut the thin aluminum alloy tube; if the aluminum alloy tube is a large or medium-sized thick aluminum alloy tube, after it is adjusted and fixed in the above manner, the hydraulic rod 7 is also controlled to retract, so that the cutting blade 6 moves downward to cut the aluminum alloy tube. At this time, the cutting blade 6 only moves downward to a degree slightly larger than the wall thickness of the aluminum alloy tube for cutting, and the second motor 17 is controlled to work at the same time, by driving the first gear 11 engaged with the second gear 16 to rotate, and the clamping block 15 is fixedly installed on the first gear 11, and the aluminum alloy tube is clamped and fixed, so that the first gear 11 can drive the aluminum alloy tube to rotate, and cooperate with the cutting action of the cutting blade 6, so that the aluminum alloy tube can rotate during the cutting process, so as to achieve uniform cutting of the outer circle of the aluminum alloy tube and improve the cutting quality; at the same time, the cutting depth of the cutter is effectively reduced, and the service life of the cutter is improved.
