Description

Technical Field

[0001] The invention belongs to the technical field of dust collection for cutting machines, in particular to a dust collection device for a seamless steel pipe cutting machine. Background Art

[0002] During the production and processing of seamless steel pipes, the head of the steel pipe body needs to be cut to make the head of the pipe body smoother. Currently, a head cutter is usually used. The clamping mechanism of the head cutter is used to clamp and fix the steel pipe, and the steel pipe is cut by a cutting disc to ensure the cutting efficiency of the head of the steel pipe body. However, a large amount of cutting debris will be generated in the process of cutting the steel pipe, which seriously pollutes the working environment.

[0003] In the related art, the current seamless steel pipe head cutting machine is provided with a collection box at the bottom of the cutting mechanism to collect the debris generated by cutting. However, since the debris is light, it will be scattered to various positions of the head cutting machine and cannot be accurately collected in the collection box, causing the debris to enter the various components of the head cutting machine, resulting in the accumulation of debris, affecting the performance of the components, or being inhaled by the staff, causing health damage. At the same time, it is very inconvenient to clean up, resulting in high labor intensity.

[0004] Therefore, there is an urgent need for a dust suction device for a seamless steel pipe cutting machine to improve the problem of debris scattering during the steel pipe cutting process, thereby reducing the labor intensity of the staff and preventing the cutting machine parts from being accumulated by debris and affecting their performance. Summary of the invention

[0005] The object of the present invention is to provide a dust suction device for a seamless steel pipe cutting machine to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0006] Specifically, the present invention discloses a dust suction device for a seamless steel pipe cutting machine, comprising:

[0007] A base, and a protective cover disposed on the base;

[0008] One side of the protective cover is open, and a protective plate is movably arranged along the opening of the protective cover;

[0009] A clamping mechanism and a cutting mechanism are provided in the protective cover, and the clamping mechanism and the cutting mechanism are respectively connected to the base;

[0010] A dust suction mechanism is provided through the top of the protective cover, and the dust suction mechanism is connected with an air suction pump.

[0011] The dust suction device for the seamless steel pipe cutting machine according to the present invention has at least the following beneficial effects:

[0012] The dust suction device of the seamless steel pipe head cutting machine places the steel pipe to be cut in the protective cover of the head cutting machine, so as to form a closed steel pipe cutting space, clamps and fixes the steel pipe by the clamping mechanism, and cuts the steel pipe by the cutting mechanism. During the steel pipe cutting process, a large amount of debris generated is automatically adsorbed and cleaned by the dust suction mechanism on the top of the protective cover. Compared with the traditional steel pipe head cutting machine, the present invention effectively reduces the debris scattered in various corners inside the head cutting machine, reduces the labor intensity of manual cleaning, and improves the working comfort and efficiency.

[0013] In addition, it avoids the long-term accumulation of debris scattered on the clamping mechanism and the cutting mechanism, which leads to reduced clamping stability of the clamping mechanism, causing vibration or shaking when the steel pipe is cut, affecting the cutting accuracy, and the debris causing wear on the cutting mechanism, affecting the cutting efficiency, ensuring the performance and service life of each component inside the head cutting machine, and improving the cutting efficiency and accuracy of the steel pipe.

[0014] As a further solution of the present invention: a slide groove is arranged on one side of the top of the protective cover close to the opening, and the protective plate is slidably arranged in the slide groove.

[0015] Since a slide groove is arranged on one side of the top of the protective cover near the opening, the protective plate is slidably arranged in the slide groove, so that the protective plate can slide in the slide groove, thereby opening and closing the opening of the protective cover, which is convenient for the steel pipe processing parts to enter and exit the cutting machine, and during the cutting process, the opening of the protective cover is closed to prevent debris from overflowing from the opening of the protective cover, avoid damage to personnel health and pollution to the environment, and improve the convenience and safety of operation.

When the steel pipe is clamped, the first ring body and the second ring body of the clamping ring are respectively applied with force in the radial direction of the clamping ring, so that the first ring body and the second ring body are expanded. At this time, the plurality of compression springs are compressed, and the diameter of the clamping ring is expanded, so that the steel pipe is conveniently placed in the clamping ring. When the steel pipe is in the middle of the clamping ring, no force is applied to the first ring body and the second ring body. The first ring body and the second ring body of the clamping ring are retracted by the resilience of the plurality of compression springs themselves, thereby generating a clamping force on the steel pipe, and ensuring the stability and reliability of the steel pipe clamping; and the clamping ring can clamp steel pipes of different diameters, thereby improving the applicability and versatility of the device.

[0019] As a further solution of the present invention: the cutting mechanism comprises a cutting frame, a cutting disc is arranged on one side of the cutting frame close to the clamping mechanism, and the bottom of the cutting frame is connected to the base.

[0020] Since the cutting mechanism includes a cutting frame, a cutting disc is arranged on one side of the cutting frame close to the clamping mechanism, so that the cutting disc is arranged corresponding to the steel pipe clamped by the clamping mechanism, after the clamping mechanism firmly clamps the steel pipe, the steel pipe is cut by the cutting disc, and the bottom of the cutting frame is connected to the base, which effectively enhances the stability and reliability of the cutting mechanism when cutting the steel pipe, and improves the cutting efficiency and accuracy of the steel pipe.

[0021] As a further solution of the present invention: a lifting device is arranged on the inner top wall of the cutting frame, a motor is arranged on the bottom of the lifting device, and an output shaft of the motor is connected to the cutting disc.

[0022] As a further solution of the present invention: the lifting device is a hydraulic telescopic sleeve rod, the hydraulic telescopic sleeve rod comprises an outer sleeve rod and an inner sleeve rod, the outer sleeve rod is connected to the inner top wall of the cutting frame, and the bottom of the inner sleeve rod is connected to the motor.

[0024] As a further solution of the present invention: the dust suction mechanism includes a plurality of air supply pipes, connecting pipes are arranged between the plurality of air supply pipes, an air extraction pipe is arranged on the connecting pipe, and the air extraction pipe is connected to an external air extraction pump.

[0025] As a further solution of the present invention: a plurality of suction nozzles are evenly arranged at the bottom of the plurality of gas delivery pipes, and a plurality of the suction nozzles are inserted into the protective cover.

[0026] Since the dust suction mechanism includes a plurality of air pipes, connecting pipes are arranged between the plurality of air pipes, an exhaust pipe is arranged on the connecting pipe, and the exhaust pipe is connected to an external exhaust pump; a plurality of suction nozzles are evenly arranged at the bottom of the plurality of air pipes, and the plurality of suction nozzles are penetrated in the protective cover; the plurality of suction nozzles at the bottom of the plurality of air pipes can effectively cover the internal space of the protective cover, so that the debris generated during the steel pipe cutting process can be timely and accurately adsorbed, and the debris is prevented from being scattered to various corners or components of the head cutting machine, thereby achieving accurate dust suction of the cutting area and improving the effect and efficiency of the dust suction.

[0027] As a further solution of the present invention: a dust hood is arranged at the bottom of the suction nozzle, and the width of the bottom of the dust hood is greater than the width of the top of the dust hood.

[0028] By arranging a dust hood at the bottom of the suction nozzle, the width of the bottom of the dust hood is greater than the width of the top of the dust hood, and the dust hood can effectively increase the suction area of ​​the suction nozzle, and cover the space inside the protective cover more comprehensively, ensuring that the suction nozzle can absorb and capture the debris scattered during the cutting of the steel pipe over a large area through the dust hood, reduce the diffusion of the debris, and further improve the dust suction effect and efficiency of the device.

[0039] Specifically, the dust collecting device of the seamless steel pipe cutting machine places the steel pipe to be cut in the protective cover 2 of the cutting machine, so as to form a closed steel pipe cutting space, clamps and fixes the steel pipe through the clamping mechanism 4, and cuts the steel pipe through the cutting mechanism 5. During the steel pipe cutting process, a large amount of debris generated is automatically adsorbed and cleaned by the dust collecting mechanism 6 on the top of the protective cover 2. Compared with the traditional steel pipe cutting machine, the present invention effectively reduces the debris scattered in various corners inside the cutting machine, reduces the labor intensity of manual cleaning, and improves the working comfort and efficiency.

[0040] In addition, it avoids the long-term accumulation of debris scattered on the clamping mechanism 4 and the cutting mechanism 5, which leads to reduced clamping stability of the clamping mechanism 4, causing vibration or shaking when the steel pipe is cut, affecting the cutting accuracy, and the debris causing wear on the cutting mechanism 5, affecting the cutting efficiency, thereby ensuring the performance and service life of each component inside the head cutting machine and improving the cutting efficiency and accuracy of the steel pipe.

A plurality of compression springs 44 are provided between the clamping ring 43 and the inner wall of the through hole 42. When clamping the steel pipe, the first ring body 431 and the second ring body 432 of the clamping ring 43 are respectively applied along the radial direction of the clamping ring 43. Apply force to expand the first ring body 431 and the second ring body 432. At this time, the compression springs 44 are compressed, and the diameter of the clamping ring 43 is enlarged, which makes it easier for the steel pipe to be placed in the clamping ring 43. When the steel pipe is in the middle of the clamping ring 43, no force is applied to the first ring body 431 and the second ring body 432. The resilience of the compression springs 44 themselves retracts the first ring body 431 and the second ring body 432 of the clamping ring 43, thereby generating a clamping force on the steel pipe, ensuring the stability and reliability of the steel pipe clamping. The clamping ring 43 can clamp steel pipes of different diameters, thereby improving the applicability and versatility of the device.
