Description
Technical field
The present invention relates to a kind of cutting machine, specifically refer to steel pipe cutting waste material collection device.
Background technology
Seamless steel pipe is that one has hollow section, periphery does not has jointed strip steel.Steel pipe has hollow section, and a large amount of pipelines being used as conveyance fluid, such as transfer oil, natural gas, coal gas and water and the pipeline etc. of some solid material.Steel pipe is compared with the solid steel such as round steel, when bending resistance torsional strength is identical, lighter in weight, is a kind of economic section steel products, it is widely used in manufacture structural member and machine components, such as the steel scaffold etc. in oil drill rocker, truck drive shaft, bicycle rack and construction.Manufacturing ring-shaped work pieces with steel pipe, can improve stock utilization, simplify manufacturing process, save material and machining period, such as rolling bearing lasso, very heavy top cover etc., the most extensive steel pipe manufactures.Steel pipe or the indispensable material of various conventional weapon, gun barrel, gun barrel etc. will manufacture by steel pipe.Steel pipe can be divided into pipe and shape tube by the difference of cross-sectional area shape.Owing to, under conditions of girth is equal, the area of a circle is maximum, can carry more fluid with round tube.Additionally, ring cross-section is when bearing interiorly or exteriorly radial pressure, stress is more uniform, and therefore, most steel pipes are pipes.
In the cutting processing of seamless steel pipe, need to add every now and then coolant to steel pipe cut place, to ensure the efficiency of cutting and to reach to protect the purpose of cutting blade；After having cut, steel pipe is in being pushed into mechanism's release cutting room, but the coolant remaining in steel duct can spill to surrounding when steel pipe movement with chip, not only affect the quality of operating environment, and the chip of pipe cutting is scattered everywhere and is also easy to cause operator to slip and falls, and causes certain potential safety hazard.
Summary of the invention
It is an object of the invention to provide steel pipe cutting waste material collection device, the coolant remained in pipe after the cutting of easy cleaning steel pipe and chip, it is to avoid coolant and chip splashes, it is ensured that the neat and tidy of operating environment.
The purpose of the present invention is achieved through the following technical solutions:
Steel pipe cutting waste material collection device, including support shaft and tube seat, described tube seat rotates and is arranged in support shaft, described support shaft is fixed on cutting machine, is provided with collecting tank in end, described tube seat one end, and the other end of tube seat is provided with motor, rectangle blind hole is had in the bottom of tube seat, it is provided with multiple pulley in rectangle blind hole, also includes that position-limit mechanism, described position-limit mechanism are arranged on tube seat on the end of motor one end.The present invention operationally, steel pipe after cutting by cutting room in be pushed out to tube seat, electric machine rotation drives tube seat to rotate in support shaft, and steel pipe rotates with tube seat, and finally concentration is deposited on the transporting equipment near cutting machine；Being pushed back with in rotary course at tube seat, the coolant of residual can flow out automatically with chip in steel pipe, and the coolant of outflow and chip are focused on by operator to the waste tank under cutting machine in the process bottom collection of collecting tank；Wherein during steel pipe is pushed back, multiple pulleys of tube seat bottom land can make the sliding friction between steel pipe and tube seat bottom land become rolling friction, reduce the load pushed back, also the mutual abrasion between steel pipe and tube seat is avoided, and in tube seat rotation process, the anglec of rotation of tube seat can be limited by the position-limit mechanism being arranged on tube seat, and the start-stop of motor can be carried out Automated condtrol simultaneously, ensure that steel pipe coolant after dicing is rapidly and efficiently carried out with chip cleaning process, also coolant and chip splashes are avoided, it is ensured that the neat and tidy of operating environment.
Described position-limit mechanism includes that arc block, described arc block are arranged on tube seat, is provided with loop in support shaft, and arc block is correspondingly arranged with loop, is provided with travel switch and spring on the end, two ends of loop, and travel switch is connected with motor.When driven by motor tube seat rotates, arc block rotates with tube seat, when the end of arc block contacts with each other with the end of loop, spring is compressed, and arc block triggers travel switch, and travel switch controls motor power-off, tube seat and motor stalls, the steel pipe in tube seat is because inertia is thrown out of；When spring arrives maximum compression limit, springback, arc block separates with travel switch, travel switch controls motor and is rotated further, when the other end of arc block contacts with the other end of loop, the travel switch being arranged on loop other end end controls motor stalls, and tube seat resets, so residual coolant in tube seat steel pipe incessantly is cleared up with chip, improves the collection efficiency of crumb mixture.
The bottom land being provided with horizontal plane and inclined plane, described horizontal plane and tube seat in described collecting tank is same in one plane, and the level height of horizontal plane is more than inclined plane, also includes the transition cambered surface being arranged between horizontal plane and inclined plane.Crumb mixture can be collected by the collecting tank of abnormity thoroughly, collecting tank inner horizontal is maintained at sustained height with the bottom land of tube seat, make tube seat when rotating, crumb mixture in pipe is discharged smoothly, process through transition cambered surface Yu inclined plane, chip be blended in collecting tank will not splash, flow out collecting tank with being allowed to fast and stable.
Being tiltedly installed with baffle plate on the side of described tube seat, the angle between described baffle plate and tube seat is 115 ° ~ 135 °.When tube seat rotates, the steel pipe in groove directly falls, and easily collides with ground and causes steel tube surface to cave in；The baffle plate being obliquely installed on the side of tube seat, and the angle between baffle plate and tube seat is 115 ° ~ 135 °, can buffer the steel pipe fallen because of rotation, reduces the kinetic energy before steel pipe falls, it is to avoid steel pipe is impaired.
Also include that protective pad, described protective pad are arranged on the junction of described tube seat and described collecting tank..It is pushed in tube seat after steel pipe cutting, and between tube seat and collecting tank, junction easily rubs with outer surface of steel tube, and then cause the mutual abrasion between steel pipe and tube seat, collecting tank；The setting of protective pad can reduce the friction between three, strengthens the service life of the present invention while reducing abrasion.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, steel pipe of the present invention cutting waste material collection device, during steel pipe is pushed back, multiple pulleys of tube seat bottom land can make the sliding friction between steel pipe and tube seat bottom land become rolling friction, reduce the load pushed back, also the mutual abrasion between steel pipe and tube seat is avoided, and in tube seat rotation process, the anglec of rotation of tube seat can be limited by the position-limit mechanism being arranged on tube seat, and the start-stop of motor can be carried out Automated condtrol simultaneously, ensure that steel pipe coolant after dicing is rapidly and efficiently carried out with chip cleaning process, also coolant and chip splashes are avoided, ensure the neat and tidy of operating environment；
2, steel pipe of the present invention cutting waste material collection device, when spring arrives maximum compression limit, springback, arc block separates with travel switch, and travel switch controls motor and is rotated further, when the other end of arc block contacts with the other end of loop, the travel switch being arranged on loop other end end controls motor stalls, tube seat resets, and the residual coolant in such tube seat steel pipe incessantly is cleared up with chip, improves the collection efficiency of crumb mixture.
