Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0032] The present application will be further described below in connection with the embodiments.

[0033] Embodiment:

[0034] Please refer to Figures 1-7 The present application provides a technical solution: a feeding device for seamless steel pipe processing, comprising:

[0035] The operation main body 1 comprises the processing table top 11, the top of which is fixedly connected with the feeding part 12 for placing external steel pipes, the outer surface of the feeding part 12 is fixedly connected with the guide pipe 13, and the inner wall of the guide pipe 13 is slidably connected with the telescopic device 14 for driving the external steel pipes;

[0036] The clamp assembly 2 comprises the fixed mold 21 and the movable mold 22, the processing table top 11 is detachably fixedly connected with the inside of the fixed mold 21 through the first mounting plate 23 arranged on the top thereof, and the processing table top 11 is slidably connected with the inside of the movable mold 22 through the second mounting plate 24 arranged on the top thereof;

[0037] The feeding part 12 includes a hopper 121 fixedly connected with the top of the machining table 11 through a support frame 122 arranged on the outer surface thereof, and the end surface of the guide pipe 13 is fixedly communicated with the inside of the hopper 121. The hopper 121 is rotatably connected with a hopper bin 123 through a rotating rod at the top thereof. The hopper bin 123 is provided with two hopper bins symmetrically distributed with the hopper 121 as the center. The support frame 122 is fixedly connected with an inclined plate 124 which is in close contact with the lower surface of the hopper bin 123 at the top thereof. The gravity of the steel pipe drives the two hopper bins 123 to expand outward. The support frame 122 is fixedly connected with the inclined plate 124 which is in close contact with the lower surface of the hopper bin 123 at the top thereof. The hopper bin 123 is fixedly positioned, and there is a certain spacing between the two hopper bins 123 (the spacing is much smaller than the diameter of the steel pipe).

[0038] The center line of the annular space surrounded by the fixed mold 21 and the movable mold 22 coincides with the center line of the guide pipe 13. The hopper 121 is provided with a discharging hole 1211 on the side away from the guide pipe 13.

[0039] The outer surface of the hopper bin 123 is fixedly connected with a plurality of groups of protrusions 1231. The inclined plate 124 is slidably connected with an L-shaped rod 125 through a support block 1241 arranged at the end surface thereof. The L-shaped rod 125 is fixedly connected with a smooth ball 1251 which is in close contact with the outer surface of the protrusion 1231 at the end thereof close to the support block 1241. The end of the L-shaped rod 125 away from the smooth ball 1251 is fixedly connected with the telescopic rod of the telescopic device 14. The telescopic rod on the telescopic device 14 slides along the inner wall of the guide pipe 13 to push the steel pipe at the bottom of the hopper 121. At the same time, the telescopic rod on the telescopic device 14 drives the L-shaped rod 125 to move synchronously. The L-shaped rod 125 slides along the inside of the support block 1241 to drive the smooth ball 1251 to slide synchronously. The smooth ball 1251 repeatedly pushes the protrusions 1231 on the outer surface of the hopper bin 123 in a short distance without interruption, thereby driving the hopper bin 123 to reciprocate and vibrate, so that the steel pipe in the hopper bin 123 rapidly falls, avoiding the situation that the steel pipe in the hopper bin 123 is clamped during the sliding process.

[0040] The first mounting plate 23 is slidably connected with a first straight rod 231 which is clamped with the outer surface of the fixed mold 21. A plurality of outer ends of the first straight rods 231 are fixedly connected with a connecting plate 232 which is tightly attached to the outer surface of the first mounting plate 23 through a threaded group. The fixed mold 21 is threadedly connected with the inside of the first mounting plate 23 through an internal hexagonal screw.

[0041] The second mounting plate 24 is slidably connected with the outer surface of the movable mold 22 through a second straight rod 241 arranged on the outer surface thereof. The movable mold 22 is provided with a pneumatic telescopic rod 25 fixedly connected with the top of the machining table 11 on the side away from the fixed mold 21.

[0042] The movable die 22 comprises a module 221, a template 222 and a magnetic plate 223, which are sequentially arranged from left to right, the module 221 is fixedly connected with the outer end of the pneumatic telescopic rod 25 away from the magnetic plate 223, the magnetic plate 223 is nested in the module 221, the outer surface of the magnetic plate 223 is magnetically connected with the outer surface of the template 222, and the module 221 is provided with a clamping groove 224 which is slidably connected with the outer surface of the template 222 away from the pneumatic telescopic rod 25.

[0043] The fixed die 21 is fixedly connected with a pin rod 211 on the side close to the template 222, the pin rod 211 extends to the outside through the template 222 and the module 221 sequentially and away from the fixed die 21, the fixed die 21 is connected with a strong spring 212 through a straight hole arranged in the inside of the fixed die 21, and the strong spring 212 is fixedly connected with the outer surface of the template 222 away from the fixed die 21. Since the outer surface of the magnetic plate 223 is magnetically connected with the outer surface of the template 222, the template 222 is subjected to the magnetic force of the magnetic plate 223 and slides along the outer surface of the pin rod 211 synchronously, and then the distance between the template 222 and the fixed die 21 is continuously increased, the flared steel pipe is subjected to the influence of its own gravity, falls into the discharging hole 5 from the fixed die 21, and the automatic discharging of the steel pipe is realized. With the increase of the distance between the template 222 and the fixed die 21, when the elastic force of the strong spring 212 is greater than the magnetic force of the template 222 and the magnetic plate 223, the template 222 is separated from the magnetic plate 223, and with the strong spring 212 close to the fixed die 21, the strong spring 212 is in the balanced state, at this time, the template 222 and the module 221 are reset to the initial position, and the flaring is carried out next time.

[0044] The positioning plate 3 is further arranged, and the bottom of the positioning plate 3 is slidably connected with the top of the machining table 11, the side of the positioning plate 3 is provided with the electric telescopic rod 4 which is fixedly connected with the top of the machining table 11, the inside of the machining table 11 is provided with the discharging hole 5 which is located between the first mounting plate 23 and the second mounting plate 24. The telescopic rod on the telescopic device 14 slides along the inner wall of the guide pipe 13, pushes the steel pipe at the lowermost position of the material box 121, drives the steel pipe to slide along the inner wall of the material box 121, passes through the discharging hole 1211 and slides into the adjacent fixed die 21 and movable die 22, and then the steel pipe is attached to the positioning plate 3, is subjected to the control of the PLC, and before the telescopic device 14 is pushed, the electric telescopic rod 4 pushes the positioning plate 3 to slide forward, after the steel pipe is attached to the positioning plate 3, the electric telescopic rod 4 resets the positioning plate 3, and then the flaring is carried out on the steel pipe.

[0045] Reference Figures 1-7The existing steel pipe flaring process is: the product to be flared is transported to the flaring equipment workbench, the port to be flared is placed neatly in front of the flaring punch, the clamp limit is adjusted to correspond to the flaring size, the steel pipe is placed in the flaring clamp and closely contacts the static die groove, the pipe port is aligned with the clamp limit, the foot switch is pressed down, and flaring is performed; after the flaring machine completes flaring, the clamp is loosened, the steel pipe is taken out, whether the flared part pipe port is round, whether there is flared cracking, head skewing, pipe port skewing, etc. is observed, whether there is a clamp mark, clamp collapse and other defects on the surface of the aluminum pipe is checked, and the size of the flared part (flared inner diameter, flared length, etc.) is checked with a measuring tool. However, in the above steel pipe flaring process, the feeding and alignment of the steel pipe need to be completed manually, and the overall efficiency is low.

[0046] To overcome the above-mentioned defects, the present application designs a feeding device for seamless steel pipe machining.

[0047] Specifically, the equidistant steel pipes to be flared are placed neatly on the inner wall of the hopper 123, and are affected by their own gravity and slide downward along the inner wall of the hopper 123, the steel pipes fall into the hopper box 121 (the steel pipes are placed in the hopper box 121 in single row from top to bottom), until the hopper 123 and the hopper box 121 are filled with steel pipes, then the extender 14 (preferably an electric push rod) on the operation main body 1 is started, the extension rod on the extender 14 slides along the inner wall of the guide pipe 13, pushes the steel pipe at the bottom of the hopper box 121, drives the steel pipe to slide along the inner wall of the hopper box 121, passes through the discharge hole 1211 and slides into the adjacent fixed die 21 and movable die 22, until the steel pipe is attached to the positioning plate 3 (affected by PLC control, before the extender 14 is pushed, the electric extension rod 4 pushes the positioning plate 3 to slide forward, after the steel pipe is attached to the positioning plate 3, the electric extension rod 4 pulls the positioning plate 3 to reset, then the flaring is performed), the extender 14 is reset, the extension rod on the extender 14 slides into the guide pipe 13, the extension rod on the extender 14 is completely separated from the hopper box 121, the steel pipe in the hopper box 121 is affected by its own gravity and falls to the bottom of the hopper box 121 again, the above operation is repeated to realize automatic feeding and flaring of the steel pipe.

[0048] The advantages of the feeding part 12 are:

[0049] During the continuous sliding of the steel pipe along the magazine 121, the magazine 123 stores a large amount of steel pipes, so as to avoid the clamping of the steel pipe in the magazine 123 during the sliding of the steel pipe to the magazine 121, and the L-shaped rod 125 and the protrusion 1231 are designed; initially, the top of the magazine 121 is rotationally connected with the bottom of the magazine 123 through a rotating rod, the magazine 123 is provided with two magazines which are symmetrically distributed with the magazine 121 as the center, a large amount of steel pipes are contained in the two magazines 123, the gravity of the steel pipes drives the two magazines 123 to expand outward, the top of the support frame 122 is fixedly connected with the inclined plate 124 which is attached to the lower surface of the magazine 123, the magazine 123 is limited and fixed, and there is a certain spacing between the two magazines 123 (the spacing is much smaller than the diameter of the steel pipe); during the operation, the telescopic rod on the telescopic device 14 slides along the inner wall of the guide pipe 13, and the lowermost steel pipe of the magazine 121 is pushed, at the same time, the telescopic rod on the telescopic device 14 drives the L-shaped rod 125 to move synchronously, the L-shaped rod 125 slides along the inside of the supporting block 1241, and drives the smooth ball 1251 to slide synchronously, the smooth ball 1251 repeatedly pushes the protrusion 1231 on the outer surface of the magazine 123, so as to drive the magazine 123 to reciprocate and vibrate, so that the steel pipe in the magazine 123 falls quickly, and the clamping of the steel pipe in the magazine 123 during the sliding of the steel pipe to the magazine 121 is avoided.

[0050] The advantages of the clamp assembly 2 are:

[0051] In order to realize the automatic unloading of the flared steel pipe, the operation main body 1, the clamp assembly 2 and the positioning plate 3 are combined to realize the integration of the steel pipe feeding, flaring and unloading.

[0052] Initially, the module 221 on the movable mold 22 is subjected to the pulling force of the pneumatic telescopic rod 25, the spacing between the module 221 and the fixed mold 21 is maximum, the template 222 on the movable mold 22 is in a balanced state, is subjected to the elastic force of the strong spring 212, and is in a separated state between the template 222 and the fixed mold 21, and a small spacing is formed therebetween, so that the steel pipe can be quickly slid into the space surrounded by the template 222 and the fixed mold 21.

[0053] During clamping, the pneumatic telescopic rod 25 pushes the module 221 to slide along the outer surface of the second straight rod 241, drives the magnetic plate 223 to move synchronously (the magnetic plate 223 is inlaid in the module 221 and flush with the surface of the clamping groove 224), until the clamping groove 224 formed in the module 221 is clamped into the outer surface of the template 222, drives the template 222 to clamp the steel pipe (the strong spring 212 is compressed), and the steel pipe is clamped between the template 222 and the fixed mold 21.

[0054] When loosened, the pneumatic telescopic rod 25 pulls the module 221 to slide along the outer surface of the second straight rod 241, and the magnetic plate 223 is synchronously moved. Since the outer surface of the magnetic plate 223 is magnetically connected with the outer surface of the die plate 222, the die plate 222 is synchronously slid along the outer surface of the pin rod 211 under the magnetic force of the magnetic plate 223 (at this time, the strong spring 212 is in a relaxed state), and then the distance between the die plate 222 and the fixed die 21 is continuously increased, the flared steel pipe is affected by its own gravity, falls into the discharging hole 5 and the external collecting box, and the automatic discharging of the steel pipe is realized. With the increase of the distance between the die plate 222 and the fixed die 21, the strong spring 212 is elastically deformed, and when the elastic force of the strong spring 212 is greater than the magnetic force of the die plate 222 and the magnetic plate 223 (the module 221 has not been reset to the initial position), the die plate 222 is separated from the magnetic plate 223. With the strong spring 212 approaching the fixed die 21, until the strong spring 212 is in a balanced state, at this time, the die plate 222 and the module 221 are reset to the initial position, and the next flaring is performed.
