Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent manufacturing equipment industry, and specifically relates to a high-speed metal circular sawing machine. Background Art

[0002] A metal circular saw is a machine tool for cutting various metal materials. The general cutting materials are various alloy steels. The application range of the metal circular saw is very wide and there is no industry limitation. Because this machine tool is a machine tool for cutting metal materials, all industries that can use cutting needs need to use a metal circular saw. Moreover, the cutting effect of the metal circular saw is very good, the cutting precision is very high, and it can cut workpieces in batches. It is an intelligent manufacturing equipment industry technology equipment.

[0003] A Chinese patent with announcement number CN205147474U discloses a feeding device for a high-speed metal circular saw machine, comprising a bed body, a machine head for sawing raw materials is provided on the bed body, a first slide rail is provided on the left end of the bed body, a loading platform is provided on the bed body, a slide seat is provided below the loading platform, which passes through the outside of the ball screw and is slidably connected to the slide rail, and an inner groove distributed left and right and obliquely arranged is opened in the slide seat, and a second slide rail is fixedly installed in the inner groove, and the loading platform is slidably connected to the outside of the second slide rail. The oblique arrangement of the loading platform allows the loading platform to achieve horizontal and vertical movement at the same time, which solves the problem of feeding obstacles caused by irregular or curved raw material shape, large vibration during operation of the double-guide column feeding mechanism, inability to feed too fast, easy wear, and easy deformation and breakage of the connecting rod under repeated torsion. The feeding stability of the machine tool is poor, and regular maintenance is required to ensure the normal operation of the machine tool, which is costly. Therefore, the circular saw machine runs stably and is worthy of promotion.

[0004] In the current existing technology, the jaws and clamping slider only clamp the material in the horizontal direction. However, when cutting, the cutting force such as tool impact, thermal deformation or reaction force will easily cause the material to vibrate vertically. The vibration will lead to a decrease in cutting accuracy, an increase in the surface roughness of the material, and even damage to the tool or material.

[0024] A metal circular saw is a machine tool for cutting various metal materials. The general cutting materials are various alloy steels. The application range of the metal circular saw is very wide and there is no industry limitation. Because the machine tool is a machine tool for cutting metal materials, all industries that can use cutting needs need to use a metal circular saw. Moreover, the cutting effect of the metal circular saw is very good, the cutting accuracy is very high, and it can cut workpieces in batches. It is an intelligent manufacturing equipment industry technology equipment; in the existing technology, the jaws and the clamping slider 32 only clamp the material in the horizontal direction, but when cutting, the cutting force such as tool impact, thermal deformation or reaction force, the material is prone to vertical vibration, and the vibration causes the cutting accuracy to decrease, the surface roughness of the material to increase, and even damage the tool or material.

[0025] When the bed 1 is conveying the material to be cut, the driving motor is turned on, and the sprocket in the sprocket box 11 is driven by the driving motor to rotate, thereby driving the roller 12 to rotate, and the roller 12 is used to convey the material until the material is conveyed to the set position; when the pressing mechanism provided by the present invention is in use, the first motor 287 is turned on, and the output shaft of the first motor 287 drives the connecting shaft to rotate, and the connecting shaft drives the gear 285 and the second rotating wheel 284 to rotate, and the gear 285 drives the adjacent gear 285 to rotate in the opposite direction, and the gear 285 drives the connected connecting shaft The connecting shaft rotates in the opposite direction, driving the connected second rotating wheel 284 to rotate in the opposite direction through the connecting shaft, thereby realizing the opposite synchronous rotation of the two second rotating wheels 284, driving the adjacent belts 286 to rotate in the opposite direction through the two second rotating wheels 284, driving the first rotating wheel 283 to rotate in the opposite direction through the belt 286, driving the pin shaft to rotate in the opposite direction through the first rotating wheel 283, driving the rotating frame 281 to rotate in the opposite direction through the pin shaft, and driving the pressing roller 282 to rotate in the opposite direction through the rotating frame 281 until the two pressing rollers 282 press the top of the material to prevent the material from vibrating vertically during cutting.

[0026] like Figure 3 and Figure 4 As shown, a sliding seat 21 is slidably connected to the top inner wall of the support frame 2 through an electric guide rail, a cylinder 22 is fixed to the bottom of the sliding seat 21, and a connecting plate 23 is fixed to the output end of the cylinder 22.

[0028] like Figure 1 and Figure 4 As shown, a side plate 27 is fixedly connected to the outer wall of the cylinder 22; a dust suction pipe 272 is connected and fixedly connected to the side plate 27, and a dust suction cover 271 is installed at one end of the dust suction pipe 272 close to the cutting blade 26, and a filter assembly is provided in the dust suction cover 271; a dust suction box 274 and a fan 273 are fixedly connected to the top of the support frame 2; one end of the dust suction pipe 272 is installed on the fan 273, and the fan 273 is connected and fixedly connected to the dust suction box 274 through a connecting pipe, and a cyclone dust removal mechanism is provided in the dust suction box 274.

[0029] When the dust hood 271 provided by the present invention is in use, since the transmission parts are mostly exposed to the outside, the waste chips generated during cutting are easy to adhere to its surface, affecting the transmission between the transmission parts, thereby affecting the clamping accuracy, so that the material cannot be clamped well. By turning on the fan 273, a negative pressure is formed at one end of the dust hood 271 through the fan 273, and the debris is sucked into the dust box 274 through the dust hood 271 and the dust pipe 272 through negative pressure adsorption; by arranging a filter component on the dust hood 271, large particles of debris can be intercepted to prevent pipe blockage; and a detachable filter component is used for easy cleaning and replacement; the fan 273 provides negative pressure to suck dust, and the connecting pipe guides the airflow into the dust box 274; the cyclone dust removal mechanism in the dust box 274 separates fine dust by centrifugal force, realizes graded filtration, can reduce the wear of the fan 273 blades, and extend the life of the equipment.

[0030] like Figure 5 and Figure 6As shown, the fixing mechanism includes a cavity 231 opened in the connecting plate 23; an electric push rod 235 is fixedly connected in the cavity 231, and the output end of the electric push rod 235 is fixedly connected to a trapezoidal block 234, and the trapezoidal block 234 is slidably connected to the inner wall of the cavity 231; two mounting plates 25 are slidably inserted in the connecting plate 23, and the cutting blade 26 is installed between the two mounting plates 25; a rotating motor is provided on one side of the cutting blade 26; two moving blocks 233 are slidably connected in the cavity 231; a side of the moving block 233 close to the trapezoidal block 234 is set as an inclined surface, which cooperates with the trapezoidal block 234; an insertion block 232 is fixed on the other side wall of the moving block 233, and the insertion block 232 is respectively inserted into the top of the mounting plate 25; a reset mechanism is also provided in the cavity 231.

[0031] When the fixing mechanism provided by the present invention is in use, the cutting blade 26 will be worn out after long-term use, and the cutting blade 26 needs to be replaced. When replacing, the mounting plate 25 is inserted into the connecting plate 23, and then the electric push rod 235 is turned on. The trapezoidal block 234 is driven to move by the output end of the electric push rod 235. During the movement, the trapezoidal block 234 squeezes the moving block 233 through the two side walls of the trapezoidal block 234, and the moving block 233 slides to both sides, and the moving block 233 drives the inserting block 232 to move. The inserting block 232 is inserted into the mounting plate 25 to achieve fixation. When it needs to be disassembled, the output end of the electric push rod 235 is retracted to drive the trapezoidal block 234 to move. During the movement, the trapezoidal block 234 releases the squeezing of the moving block 233. Under the action of the reset mechanism, the moving block 233 slides toward the center, and the moving block 233 drives the inserting block 232 to move toward the center. The inserting block 232 leaves the mounting plate 25, and the mounting plate 25 can be removed.

[0032] like Figure 6 As shown, the reset mechanism includes two cross bars 236 fixed to the inner wall of the cavity 231, and a spring 237 is sleeved in the middle of the cross bars 236. The two ends of the spring 237 are respectively fixed to two moving blocks 233, and the moving blocks 233 are slidably connected on the two cross bars 236.

[0033] When the reset mechanism provided by the present invention is in use, the trapezoidal block 234 squeezes the movable block 233 through the two side walls of the trapezoidal block 234 during movement, and the movable block 233 slides to both sides, and the spring 237 is stretched. When it is to be disassembled, the output end of the electric push rod 235 is retracted to drive the trapezoidal block 234 to move. During the movement, the trapezoidal block 234 releases the squeezing of the movable block 233, and under the action of the spring 237, the movable block 233 slides toward the center.

[0034] As shown in Figure 8, one end of the bed body 1 is fixedly connected to two rectangular plates 4, and a bidirectional ball screw 41 is rotatably connected between the two rectangular plates 4 through a bearing, and two movable plates 44 are threadedly connected to the bidirectional ball screw 41; two guide rods 42 are fixedly connected between the two rectangular plates 4, and the movable plates 44 are slidably connected on the two guide rods 42; a second motor 43 is fixed to one of the rectangular plates 4, and the output shaft of the second motor 43 is fixed to one end of the bidirectional ball screw 41; a switching component is provided on the movable plate 44.

[0035] When the movable plate 44 provided by the present invention is in use, the second motor 43 is turned on, and the bidirectional ball screw 41 is driven to rotate by the output shaft of the second motor 43, and the two movable plates 44 are driven to move by the bidirectional ball screw 41, and the switching assembly is driven to move by the movable plate 44 until both sides of the material are clamped. During the movement, the movable plate 44 slides on the guide rod 42, and the guide rod 42 limits the movable plate 44 to move in the horizontal direction.

[0036] like Figure 8 As shown, the switching assembly includes a mounting bracket 48 fixed to the top of the movable plate 44, a third motor 47 fixed to the top of the mounting bracket 48, and an output shaft of the third motor 47 fixed to a connecting transverse plate 49; triangular blocks 45 and splints 46 are fixed to both side walls of the connecting transverse plate 49, respectively, and anti-slip pads are fixed to the side walls of the triangular blocks 45 and the splints 46 away from the connecting transverse plate 49.

[0037] When the switching assembly provided by the present invention is in use, some materials are steel plates and some are cylinders. When the flat steel plates need to be clamped and fixed, the connecting cross plate 49 needs to be driven to rotate by the third motor 47, and the clamping plate 46 is rotated to the side close to the material through the connecting cross plate 49, and the steel plates are clamped by the clamping plate 46; if it is cylindrical steel, the connecting cross plate 49 needs to be driven to rotate by the third motor 47, and the triangular block 45 is rotated to the side close to the material through the connecting cross plate 49; the cylindrical steel is clamped by the triangular block 45.

[0038] like Figure 2 and Figure 7 As shown, a slide groove is provided on the inner wall of the end of the bed 1 away from the rectangular plate 4, and an electric slide rail 37 is fixed in the slide groove. The electric slide rails 37 are rotatably connected to the rotating plate 3 through a slide seat; a displacement sensor 36 is fixed to the end of the slide groove close to the support frame 2, and the displacement sensor 36 is electrically connected to the electric slide rail 37; a rotating mechanism is provided at the bottom of the rotating plate 3.

[0039] When the rotating plate 3 provided by the present invention is in use, a displacement sensor 36 is set to facilitate monitoring the position of the rotating plate 3 driven by the electric slide rail 37. When the electric slide rail 37 moves the rotating plate 3 to a suitable position and reaches the value set by the displacement sensor 36, the movement is stopped. Before cutting, the rotating plate 3 needs to be rotated upward to a vertical position through the rotating mechanism to facilitate control of the cutting length of the material. After the cutting is completed, the rotating plate 3 is rotated downward to an angle through the rotating mechanism to facilitate the unloading of the material.

[0040] like Figure 7 As shown, the rotating mechanism includes a sliding rail 31 fixed to the bottom of the rotating plate 3; a slider 32 is slidably connected in the sliding rail 31, and the bottom of the slider 32 is rotatably connected to a connecting block 33 through a pin shaft; a horizontal shaft 35 is fixed to the bottom end of the bed body 1, and a hydraulic cylinder 34 is rotatably connected to the horizontal shaft 35 through a bearing, and the output end of the hydraulic cylinder 34 is fixed to the connecting block 33.

[0041] When the rotating mechanism provided by the present invention is in use, when the electric slide rail 37 drives the rotating plate 3 to slide, since the two ends of the hydraulic cylinder 34 are rotatably connected, there is no influence. When the rotating plate 3 needs to be rotated, the hydraulic cylinder 34 is turned on, and the connecting block 33 is driven to move through the output end of the hydraulic cylinder 34, and the slider 32 is driven to slide on the sliding rail 31 through the connecting block 33, driving the rotating plate 3 to rotate to a suitable angle.

[0042] like Figure 1 As shown, a plurality of rollers 38 are rotatably connected to the top of the rotating plate 3 , and the rollers 38 are symmetrically arranged on both sides of the rotating plate 3 .

[0043] When the roller 38 provided by the present invention is used, the roller 38 is set on the rotating plate 3. When unloading, the roller 38 facilitates the material to slide off the rotating plate 3, which not only reduces friction but also improves the efficiency of unloading.

[0044] Working principle: By turning on the second motor 43, the output shaft of the second motor 43 drives the bidirectional ball screw 41 to rotate, and the bidirectional ball screw 41 drives the two movable plates 44 to move, and the movable plates 44 drive the switching assembly to move until both sides of the material are clamped. During the movement of the movable plates 44, the movable plates 44 slide on the guide rods 42, and the guide rods 42 limit the movable plates 44 to move in the horizontal direction. When it is necessary to clamp and fix a flat steel plate, it is necessary to drive the connecting cross plate 49 to rotate through the third motor 47, and the clamping plate 46 is rotated to the side close to the material through the connecting cross plate 49, and the steel plate is clamped by the clamping plate 46; if the steel is cylindrical, it is necessary to drive the connecting cross plate 49 to rotate through the third motor 47, and the triangular block 45 is rotated to the side close to the material through the connecting cross plate 49; the cylindrical steel is clamped by the triangular block 45.

[0045] By turning on the driving motor, the sprocket in the sprocket box 11 is driven to rotate by the driving motor, thereby driving the roller 12 to rotate, and the roller 12 is used to transport the material until the material is transported to the set position; by driving the electric guide rail, the sliding seat 21 is driven to move by the electric guide rail, thereby realizing cutting of materials of different widths; when cutting is required, the cylinder 22 is turned on, and the connecting plate 23 and the cutting blade 26 are driven to move by the output end of the cylinder 22, so that the cutting blade 26 is suitable for cutting materials of different thicknesses; during the movement of the connecting plate 23, the connecting plate 23 drives the vertical rod 24 to slide on the protrusion, and the vertical rod 24 limits the cutting blade 26 to move in the vertical direction.

[0046] When the pressing mechanism provided by the present invention is in use, by turning on the first motor 287, the output shaft of the first motor 287 drives the connecting shaft to rotate, the connecting shaft drives the gear 285 and the second rotating wheel 284 to rotate, the gear 285 drives the adjacent gear 285 to rotate in the opposite direction, the gear 285 drives the connected connecting shaft to rotate in the opposite direction, the connecting shaft drives the connected second rotating wheel 284 to rotate in the opposite direction, thereby realizing the two second rotating wheels 284 to rotate synchronously in the opposite direction, the two second rotating wheels 284 drive the adjacent belts 286 to rotate in the opposite direction, the belt 286 drives the first rotating wheel 283 to rotate in the opposite direction, the first rotating wheel 283 drives the pin to rotate in the opposite direction, the pin drives the rotating frame 281 to rotate in the opposite direction, and the rotating frame 281 drives the pressing roller 282 to rotate in the opposite direction until the two pressing rollers 282 press the top of the material to prevent the material from vibrating vertically during cutting.

[0047] Since the transmission parts are mostly exposed to the outside, the waste chips generated during cutting are easy to adhere to their surface, affecting the transmission between the transmission parts, thereby affecting the clamping accuracy, so that the material cannot be clamped well. By turning on the fan 273, a negative pressure is formed at one end of the dust hood 271 through the fan 273, and the debris is sucked into the dust box 274 through the dust hood 271 and the dust pipe 272 through the negative pressure adsorption; by arranging a filter component on the dust hood 271, large particles of debris can be intercepted to prevent pipe blockage; and a detachable filter component is used for easy cleaning and replacement; the fan 273 provides negative pressure to suck dust, and the connecting pipe guides the airflow into the dust box 274; the cyclone dust removal mechanism in the dust box 274 separates fine dust through centrifugal force to achieve graded filtration, which can reduce the wear of the fan 273 blades and extend the life of the equipment.

[0048] The cutting blade 26 will wear out after long-term use and needs to be replaced. When replacing, the mounting plate 25 is inserted into the connecting plate 23, and then the electric push rod 235 is turned on. The trapezoidal block 234 is driven to move by the output end of the electric push rod 235. During the movement, the trapezoidal block 234 squeezes the moving block 233 through the two side walls of the trapezoidal block 234, and the moving block 233 slides to both sides, and the moving block 233 drives the insert block 232 to move. The insert block 232 is inserted into the mounting plate 25 to achieve fixation. When it needs to be disassembled, the output end of the electric push rod 235 is retracted to drive the trapezoidal block 234 to move. During the movement, the trapezoidal block 234 releases the squeezing of the moving block 233. Under the action of the spring 237, the moving block 233 slides toward the center, and the moving block 233 drives the insert block 232 to move toward the center. The insert block 232 leaves the mounting plate 25, and the mounting plate 25 can be removed.

[0049] By setting a displacement sensor 36, it is convenient to monitor the position of the rotating plate 3 driven by the electric slide 37. When the electric slide 37 moves the rotating plate 3 to the appropriate position and reaches the value set by the displacement sensor 36, the movement is stopped. Before cutting, the rotating plate 3 needs to be rotated upward to a vertical position by the rotating mechanism to facilitate the control of the cutting length of the material. After the cutting is completed, the rotating plate 3 is rotated downward to an angle by the rotating mechanism to facilitate the unloading of the material. When the electric slide 37 drives the rotating plate 3 to slide, since the two ends of the hydraulic cylinder 34 are rotatably connected, it has no effect. When the rotating plate 3 needs to be rotated, the hydraulic cylinder 34 is turned on, and the output end of the hydraulic cylinder 34 drives the connecting block 33 to move, and the connecting block 33 drives the slider 32 to slide on the sliding rail 31, driving the rotating plate 3 to rotate to a suitable larger position.
