The present invention is convenient to use, has good fixing effect, high cutting efficiency, high safety, and saves energy;

[0005] In the published patent "A Mechanical Clamping Cutter for Stainless Steel Pipes" with the patent number CN112108709A, it includes a workbench. A first motor is fixedly arranged on one side of the upper surface of the workbench. The output shaft of the first motor is fixedly connected to a lead screw through a coupling. A sliding sleeve is sleeved on the outer surface of the lead screw. The right end of the sliding sleeve is fixedly connected to a sleeve. The inside of the sleeve is hollow and is inserted with a telescopic rod. The end of the telescopic rod away from the sleeve is fixedly provided with a cutter. A fixed plate is fixedly arranged on the right side of the lead screw. There are two fixed plates and they are symmetrically arranged left and right. A box body is fixedly arranged at the bottom of the middle of the workbench. An adjustment device is arranged inside the box body. A connecting rod is fixedly connected to the opposite sides of the two fixed plates. In the present invention, by setting the adjustment device, the adjustment rod is used to drive the connecting rod and the clamping block to rotate a small angle towards the steel pipe, further clamping the steel pipe, improving the fixing effect of the steel pipe, and facilitating cutting;

[0006] In the "Cutting Device for Stainless Steel Tubes" with the published patent CN111644684A, it includes a frame, and also includes a substrate, a cutting assembly and a driving member. The substrate is fixedly connected to the lower part of the frame. One end of the substrate has a positioning structure for positioning the stainless steel tube, and the other end of the substrate has a limiting structure for limiting the stainless steel tube. The driving member is fixedly connected to the upper part of the frame and the driving member is connected to the cutting assembly. In the initial state, the cutting assembly is located above the substrate. This cutting device for stainless steel tubes has high stability;

[0007] When the above cutting device cuts and processes steel tubes, most of them are fed and cut manually. However, this feeding method is very time-consuming and laborious, which will not only reduce the later cutting efficiency, but also cause the phenomenon of cutting risks due to the manual feeding method. There is no automatic feeding mechanism to automatically feed the steel tubes, which is not convenient for the stable cutting production and processing of steel tubes in the later stage;

[0008] Therefore, we propose an efficient cutting device for stainless steel tubes with automatic feeding to solve the problems raised above. Summary of the Invention

[0009] The purpose of the present invention is to provide an efficient cutting device for stainless steel tubes with automatic feeding to solve the problem that most of the current market uses manual feeding for cutting and processing, but this feeding method is very time-consuming and laborious, which will not only reduce the later cutting efficiency, but also cause the phenomenon of cutting risks due to the manual feeding method. There is no automatic feeding mechanism to automatically feed the steel tubes, which is not convenient for the stable cutting production and processing of steel tubes in the later stage as mentioned in the above background technology.

[0010] To achieve the above purpose, the present invention provides the following technical solution: An efficient cutting device for stainless steel tubes with automatic feeding, including a fuselage, a control motor is installed above the right side thereof, and the output end of the control motor is connected to a cutting blade through a belt, and a protective shell is arranged outside the cutting blade, and an inclined grip is connected to the outer end of the cutting blade;

[0011] It also includes: a fuselage, a feeding groove is opened on the front side thereof, and a steel tube body is corresponding above the feeding groove. Sliding grooves are opened on both sides above the fuselage for installing positioning seats, and the structures of the two positioning seats are the same. The inner sides of the two positioning seats correspond to the steel tube body, and a cutting blade is corresponding above the steel tube body. A filter box is installed on the upper right side of the fuselage by screws, and a hose is hermetically penetrated and connected to the outside of the filter box, and the outer end of the hose is hermetically connected to a smoking disc, and the smoking disc is rotatably installed on the outer side of the right end of the fuselage;

[0012] The fuselage has a discharge box installed with screws above its left side. A sliding table is provided on the right side of the discharge box. Inside the discharge box, a row of steel pipe bodies are placed in a grooved slot. The sliding table has a baffle slidably installed through a return spring in a grooved slot at its bottom. The baffle is in an inverted "L" shape, and a steel pipe body corresponds to the upper side of the baffle. The discharge box has a push plate slidably installed through a grooved slot inside it, and a steel pipe body corresponds to the outer side of the push plate. The discharge box has a feed port opened above it and a discharge port opened on its outer side.

[0013] Preferably, the discharge box has a top plate slidably installed in a grooved slot inside it. Both ends of the bottom of the top plate are connected to the inner wall of the discharge box through compression springs. At the same time, a steel pipe body is placed above the top of the top plate. The steel pipe body placed above the top plate can be ejected to the outer side of the push plate by the elastic force of the two compression springs themselves.

[0014] Preferably, the discharge box has a moving seat slidably installed in a grooved slot inside it. A push plate is installed with screws at the outer end of the moving seat, and a steel pipe body corresponds to the outer end of the push plate. The moving seat has a first half gear rotatably installed in a grooved slot inside it. The output end of the first half gear is connected to a driving mechanism. Both the upper and lower sides of the first half gear are meshed and connected to the moving seat through first racks. Moreover, both of the two first racks are arranged on the upper and lower sides of the inner wall of the moving seat. The moving seat can be driven to reciprocate left and right in position while the first half gear rotates. At this time, the push plate arranged at the outer end of the moving seat can be driven to intermittently push the steel pipe body for automatic feeding, avoiding the complex steps of manual feeding required by traditional cutting devices.

[0015] Preferably, two pull ropes are wound and connected to the outer end of the grip. The outer ends of the two pull ropes are both connected to the output end of a transmission gear through guide wheels. Both the outer sides above the two transmission gears are meshed and connected to a positioning seat through second racks. The two positioning seats can be driven to contract and move simultaneously through the two second racks while the two transmission gears rotate. Then, the steel pipe bodies corresponding to the inner sides of the two positioning seats can be clamped and positioned.

[0016] Preferably, the output ends of both of the two transmission gears are wound and connected with first torsion springs. The outer ends of the two first torsion springs are both connected to both ends of the inner wall of the fuselage. The elastic force of the two first torsion springs can be used to conveniently perform elastic reset on the two rotating transmission gears, so that the two positioning seats can be automatically expanded and moved.

[0017] Preferably, anti-slip pads are adhesively connected to the inner sides of both of the two positioning seats. The structures of the two anti-slip pads are the same. The inner sides of the two anti-slip pads are both adhesively connected to the outer side wall of the steel pipe body. The friction between the steel pipe body and the two positioning seats can be increased through the two anti-slip pads, avoiding the phenomenon of dislocation and offset of the steel pipe body during later cutting processing, and improving the cutting stability of the cutting device.

[0018] Preferably, inside the right side of the fuselage, a rotating gear is rotatably installed in a groove, and a second half gear is meshed and connected to the outside of the rotating gear. Moreover, the output end of the second half gear is connected to a smoking tray. For the second half gear, a second torsion spring is wound and connected to its output end, and the outer end of the second torsion spring is connected to the inner side wall of the fuselage. The elastic force of the second torsion spring itself can be used to conveniently elastically reset the position of the second half gear after rotation. Subsequently, the smoking tray can be driven to swing reciprocally in position to absorb soot and dust, preventing it from spreading in the air and affecting the health and safety of the staff.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] (1) By arranging a row of steel pipe bodies in a groove inside the discharge box, and then installing a top plate at the bottom of the discharge box through a compression spring, the elastic force of the two compression springs can be used to automatically eject a row of steel pipe bodies placed above the top plate to the outside of the push plate. Then, through the push plate, a row of steel pipe bodies can be successively pushed and extruded to the outside of the discharge box. Then, through the sliding table, a row of steel pipe bodies can be successively pushed out to the bottom of the cutting blade for automatic feeding and cutting processing, thereby improving the cutting efficiency of the cutting device.

[0021] (2) Further, by connecting a driving mechanism to the output end of the first half gear, the driving mechanism can drive the first half gear to drive the push plate connected to the outer end of the moving seat to reciprocate left and right through two rows of first racks. At this time, the steel pipe bodies can be intermittently pushed out to the outside of the discharge box through the reciprocating push plate, which is more time-saving and labor-saving.

[0022] (3) By winding two pull ropes around the outer end of the grip, and then connecting the outer ends of the two pull ropes to the output ends of two transmission gears through guide wheels. Since the two transmission gears are installed at both ends inside the fuselage through first torsion springs, when pressing the grip to drive the cutting blade to cut the steel pipe body, the two first torsion springs will rotate and reset the two transmission gears through their own elastic forces. Then, the two transmission gears will drive the two positioning seats to contract and move through two second racks. At this time, the two positioning seats will automatically clamp and position the placed steel pipe body, avoiding the need for manual automatic positioning and clamping of the steel pipe body in the later stage, and improving the cutting efficiency of the cutting device.

[0023] (4) Further, by fitting and connecting anti-slip pads to the outer side walls of the steel pipe bodies on the inner sides of the two positioning seats, the friction between the positioning seats and the steel pipe bodies can be increased through the two anti-slip pads, preventing the steel pipe bodies from being displaced and offset during later cutting processing.

[0024] (5) A filter box is installed on the upper right end of the fuselage with screws, and then a groove is opened on the outside of the filter box and hermetically connected with a hose. At the same time, the outer end of the hose is hermetically connected with a smoking tray, and a cutting blade corresponds to the outer end of the smoking tray. When the cutting blade cuts and processes the steel pipe body, the cutting smoke can be conveyed to the inside of the filter box through the smoking tray for filtration treatment, avoiding the smoke from spreading in the air and causing harm to the health of the staff.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] The present invention provides the following technical solutions:

[0039] In the first embodiment, in order to solve the problem that the existing cutting device cannot automatically load and cut a row of steel pipe bodies 8, the following is disclosed:

[0040] The body 1 is provided with a control motor 2 above its right side, and the output end of the control motor 2 is connected to a cutting blade 3 through a belt. A protective shell 4 is arranged outside the cutting blade 3, and an inclined grip 5 is connected to the outer end of the cutting blade 3;

[0041] It further includes: The body 1 is provided with a feeding groove 9 on its front side, and a steel pipe body 8 corresponds to the upper part of the feeding groove 9. Both sides above the body 1 are provided with positioning seats 21 that are slidably installed in grooves, and the structures of the two positioning seats 21 are the same. The inner sides of the two positioning seats 21 correspond to the steel pipe body 8, and a cutting blade 3 corresponds to the upper part of the steel pipe body 8. The body 1 is provided with a filter box 12 screwed above its right side, and a hose 11 is hermetically penetrated and connected to the outer side of the filter box 12 through a groove. The outer end of the hose 11 is hermetically connected to a smoking tray 10, and the smoking tray 10 is rotatably installed outside the right end of the body 1;

[0042] The fuselage 1 has a discharge box 6 installed with screws above its left side. A slide table 7 is provided on the right side of the discharge box 6. A row of steel pipe bodies 8 are placed in a grooved manner inside the discharge box 6. The slide table 7 has a groove at its bottom and is slidably installed with a baffle 13 through a return spring 14. The baffle 13 is in an inverted "L" shape, and the steel pipe body 8 corresponds to the upper part of the baffle 13. The discharge box 6 has a push plate 18 slidably installed through a groove inside it, and the steel pipe body 8 corresponds to the outer side of the push plate 18. The discharge box 6 has a feed port opened above it and a discharge port opened on its outer side.

[0043] The discharge box 6 has a top plate 19 slidably installed through a groove inside it. Both ends of the bottom of the top plate 19 are connected to the inner wall of the discharge box 6 through compression springs 20. At the same time, the steel pipe body 8 is placed above the top of the top plate 19. The discharge box 6 has a moving seat 15 slidably installed through a groove inside it. A push plate 18 is installed with screws at the outer end of the moving seat 15, and the steel pipe body 8 corresponds to the outer end of the push plate 18. The moving seat 15 has a first half gear 16 rotatably installed through a groove inside it. The output end of the first half gear 16 is connected to a driving mechanism. Both the upper and lower sides of the first half gear 16 are meshed and connected to the moving seat 15 through first racks 17. Moreover, both of the two first racks 17 are arranged on the upper and lower sides of the inner wall of the moving seat 15.

[0044] As Figures 1 - 4 shown, when the cutting device cuts the steel pipe body 8, the two compression springs 20 will push out the steel pipe body 8 placed on the top of the top plate 19 through their own elastic force. Then, the driving mechanism drives the first half gear 16 to drive the push plate 18 arranged at the outer end of the moving seat 15 through the two first racks 17 to push the steel pipe body 8 to move intermittently to the outside of the discharge box 6. Subsequently, the steel pipe body 8 will be conveyed to the bottom of the cutting blade 3 through the slide table 7 for efficient cutting processing, avoiding the traditional cutting device that requires manual feeding for cutting processing, with better practicability, more time-saving and labor-saving, and improving the cutting efficiency of the cutting device.

[0045] Embodiment 2, different from Embodiment 1, can automatically clamp and position the steel pipe body 8 when pressing the grip 5 to drive the cutting blade 3 to cut the steel pipe body 8, and discloses:

[0046] The handle 5 has two pulling ropes 23 wound and connected to its outer end, and the outer ends of the two pulling ropes 23 are both connected to the output ends of the transmission gears 24 through guide wheels. Moreover, the outer sides above the two transmission gears 24 are both meshed and connected to the positioning seats 21 through the second racks 26. The output ends of the two transmission gears 24 are both wound and connected with the first torsion springs 25, and the outer ends of the two first torsion springs 25 are both connected to both ends of the inner wall of the fuselage 1. The inner sides of the two positioning seats 21 are both adhesively connected with anti-slip pads 22, and the structures of the two anti-slip pads 22 are the same. Moreover, the inner sides of the two anti-slip pads 22 are both adhesively connected to the outer side wall of the steel pipe body 8.

[0047] As Figures 1 - 8 shown, when pressing the handle 5 to drive the cutting blade 3 to cut the steel pipe body 8, the pulling ropes 23 connected to both ends of the handle 5 will become loose. At this time, the two transmission gears 24 can be reset and rotated by the elastic force of the two first torsion springs 25 themselves. At this time, the two transmission gears 24 will drive the two positioning seats 21 through the two second racks 26 to clamp and position the steel pipe body 8 through the anti-slip pads 22. The friction between the steel pipe body 8 and the two positioning seats 21 can be increased through the two anti-slip pads 22, avoiding the phenomenon of dislocation and offset of the steel pipe body 8 during the later cutting process, improving the cutting efficiency of the cutting device. When the cutting blade 3 is reset after cutting, the two pulling ropes 23 can be pulled simultaneously through the guide wheels to drive the two transmission gears 24 to rotate simultaneously. At this time, the two positioning seats 21 can be pulled to expand and move simultaneously to facilitate the automatic feeding and loading of the steel pipe body 8 in the later stage, with better practicability.

[0048] Embodiment 3, different from Embodiment 2, is that when cutting the steel pipe body 8, the smoke generated by cutting can also be absorbed and filtered, and it is disclosed that:

[0049] The fuselage 1 has a rotating gear 27 rotatably installed in a groove on the right side inside it, and the outer side of the rotating gear 27 is meshed with a second half gear 28. Moreover, the output end of the second half gear 28 is connected to a smoking disc 10. The second half gear 28 has a second torsion spring 29 wound and connected to its output end, and the outer end of the second torsion spring 29 is connected to the inner side wall of the fuselage 1.

[0050] As Figures 1 - 11As shown, when the cutting blade 3 cuts the steel pipe body 8, a large amount of smoke and dust will be generated. At this time, when the suction tray 10 is started, the floating smoke and dust will be absorbed, and then the smoke and dust will be transported to the inside of the filter box 12 through the hose 11 for filtration treatment. When the suction tray 10 absorbs the smoke and dust, the control mechanism is started to drive the rotating gear 27 to rotate. At this time, the rotating gear 27 will simultaneously drive the second half gear 28 to drive the suction tray 10 to swing. Then, the second torsion spring 29 will elastically reset the position of the rotated suction tray 10 through its own elastic force, so as to drive the suction tray 10 to swing and uniformly absorb the smoke and dust generated by cutting, avoid the smoke and dust from drifting outside and threatening the safety of the staff, improve the cutting safety of the cutting device, and thus complete a series of work.

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
