[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example: Figure 1-15 As shown, the fully automatic feeding, core-threading and drawing device for high-precision forming of tube materials includes:

[0040] The automatic heading mechanism 1 comprises a shell 101 and an extrusion piece 102. The shell 101 has a receiving cavity 103 and an external plug hole 104. The external plug hole 104 is for the pipe to extend into the receiving cavity 103. There are a plurality of extrusion pieces 102. The plurality of extrusion pieces 102 are received in the receiving cavity 103 and are sequentially arranged around the external plug hole 104 to form an extrusion hole 105 communicating with the external plug hole 104. Each extrusion piece 102 can translate relative to the shell 101. When any extrusion piece 102 translates, it drives each extrusion piece 102 to translate and adjust the size of the extrusion hole 105.

[0041] The quantitative conveying mechanism 2 includes a material discharging component 201 and a material loading component 202. The material discharging component 201 includes a material discharging frame group 203 and a material guide frame 204. The material discharging frame group 203 includes a material storage channel 205 and a material discharging port 206. The material storage channel 205 is used to store and release pipe fittings. The material discharging port 206 is connected to the material storage channel 205. The material guide frame 204 is rotatably connected to the material discharging frame group 203 to open and close the material discharging port 206. The material loading component 202 includes a material loading frame 207, a material loading belt 208 and a material feeding piece 209. The material loading belt 208 is arranged on the material loading frame 207 to receive the pipe fittings dropped from the material discharging port 206 and convey the pipe fittings to the material feeding piece 209.

[0042] The drawing mechanism 3 includes a drawing base 301, a drawing slide 302 and a drawing fixture 303. The drawing base 301 is arranged in front of the core-piercing base 401 and has a drawing hole 304. The drawing slide 302 is located in front of the drawing hole 304 and can move forward and backward along the drawing base 301. The drawing fixture 303 is arranged on the drawing slide 302 and is used to clamp the pipe passing through the drawing hole 304.

[0043] The core-threading mechanism 4 includes a core-threading base 401, a core-threading swing arm 402, a core-threading rope 403, a core-threading slide 404 and a core-stripping slide 405. The core-threading slide 404 and the core-stripping slide 405 are opposite to each other on the core-threading swing arm 402. The core-threading slide 404 is in the front and the core-stripping slide 405 is in the back. One end of the core-threading rope 403 is fixed on the core-stripping slide 405 and the other end is threaded on the core-threading slide 404. The core-threading swing arm 402 can be swung relative to the core-threading base 401 to one side of the feeding piece 209 or The core-threading slide 404 swings down to the side of the drawing hole 304, and has a core-threading clamp 406 for clamping the pipe fitting when the core-threading swing arm 402 swings to the side of the feeding piece 209. The core-threading slide 404 and the core-stripping slide 405 can move forward and backward along the core-threading swing arm 402. When the core-threading slide 404 moves backward, the core-threading rope 403 penetrates the pipe fitting. The core-stripping slide 405 and the core-threading slide 404 can move forward synchronously, so that the core-threading rope 403 moves forward with the pipe fitting when the core-threading swing arm 402 swings to the side of the drawing hole 304.

[0044] The unloading mechanism 5 can push the pipe away from the drawing base 301 in the left and right directions.

[0045] When the fully automatic feeding and core-threading drawing device for high-precision forming of pipe materials is used to draw pipe fittings, the steps are as follows: first, the worker inserts the front end of the pipe fitting into the extrusion hole 105, pushes any extrusion piece 102 to drive each extrusion piece 102 to translate and narrow the extrusion hole 105 to extrude the pipe fitting, and the front end of the pipe fitting is squeezed to become flat and thinner. Then, pushes any extrusion piece 102 to drive each extrusion piece 102 to translate and expand the extrusion hole 105 to release the pipe fitting. Then, the pipe fitting with the head completed is placed in the storage channel 205. Then, the guide frame 204 opens the discharge port 206, and the pipe fitting falls out of the storage channel 205 from the discharge port 206 and falls onto the feeding belt 208. Then, the feeding belt 208 transports the pipe fitting to the feeding piece 209, and the core-threading swing arm 402 swings up to the side of the feeding piece 209. Slide along the feeding piece 209 to the core-threading slide 404, the core-threading clamp 406 clamps the pipe fitting, then, the core-threading slide 404 moves backward to allow the core-threading rope 403 to penetrate the pipe fitting, then, the core-threading swing arm 402 swings down to one side of the drawing hole 304, the core-stripping slide 405 and the core-threading slide 404 move forward synchronously to allow the front end of the pipe fitting to pass through the drawing hole 304, then, the drawing clamp 303 clamps the pipe fitting, then, the drawing slide 302 moves forward, the core-stripping slide 405 and the core-threading slide 404 move forward synchronously to allow the core-threading rope 403 to move forward with the pipe fitting, after the pipe fitting is pulled, the drawing clamp 303 releases the pipe fitting, the core-stripping slide 405 moves backward to pull the core-threading rope 403 out of the pipe fitting, and finally, the unloading mechanism 5 pushes the pipe fitting away from the drawing base 301.

[0046] It should be noted that when the pipe is drawn, the speed at which the drawing slide 302 moves forward is greater than the speed at which the core stripping slide 405 and the core insertion slide 404 move forward, and the inner diameter of the drawing hole 304 is slightly smaller than the outer diameter of the pipe.

[0047] In summary, the present embodiment provides a fully automatic loading, core-threading and drawing device for high-precision forming of pipe materials, so as to solve the problem that the middle part of the existing pipe fittings is easy to sink during the drawing process and the pipe fittings drawing quality is poor, mainly by configuring a core-threading mechanism 4, the core-threading mechanism 4 has a core-threading swing arm 402 that can swing to one side of the feeding piece 209 or the drawing hole 304, a core-threading slide 404 that moves backward along the core-threading swing arm 402 to insert the core-threading rope 403 into the pipe fitting, and a core-removing slide 405 that moves forward synchronously with the core-threading slide 404 to make the core-threading rope 403 move forward with the pipe fitting, so that the pipe fittings are stable and do not sink during the drawing process, and the drawing quality is good.

[0051] In the embodiment of the present invention, the core-threading slide 404 is provided with a positioning cylinder 407 behind the core-threading fixture 406. The positioning cylinder 407 has a core-threading hole 408 extending forward and backward. The core-threading hole 408 is for inserting the pipe when the core-threading swing arm 402 swings to the side of the feeding member 209.

[0055] In the embodiment of the present invention, the drawing fixture 303 has two drawing chucks 305 opposite to each other, and the drawing slide 302 has a distance adjustment hole 306 whose aperture gradually increases from the back to the front. The two drawing chucks 305 can move forward and backward along the distance adjustment hole 306. The side of any drawing chuck 305 facing away from the other drawing chuck 305 is obliquely pushed and matched with the hole wall of the distance adjustment hole 306. The distance between the two drawing chucks 305 gradually increases when the two drawing chucks 305 move forward, and the distance between the two drawing chucks 305 gradually decreases when the two drawing chucks 305 move backward.

The vertical arm 501 can rotate relative to the drawing base 301 to make the horizontal arm 502 parallel to the drawing base 301 or perpendicular to the drawing base 301. When the horizontal arm 502 and the drawing base 301 are perpendicular to each other, the push block 503 can move along the horizontal arm 502 to push the pipe away from the drawing base 301. The above arrangement configures the unloading mechanism 5 into a vertical arm 501, a horizontal arm 502 and a push block 503.

The feeding belt 208 is wound around the feeding frame 207, and the feeding belt 208 moves in the vertical direction around the feeding frame 207 to convey the pipe to the feeding piece 209. The above arrangement makes the pipe conveying smooth and the arrangement of each component reasonable and compact by configuring the material discharge port 206 and the feeding piece 209 to be vertically opposite to each other.

[0059] In the embodiment of the present invention, when the material guide rack 204 opens the material discharge port 206, it tilts from top to bottom toward the material loading belt 208 to guide the pipe fittings falling out of the material storage channel 205 to the material loading belt 208. The above arrangement is configured to tilt the material guide rack 204 from top to bottom toward the material loading belt 208 when the material discharge port 206 is opened, so that the pipe fittings are stably discharged.

[0060] In an embodiment of the present invention, the unloading rack group 203 has a unloading rack 210 and a material blocking rack 211, which together form a material storage channel 205.

The material blocking rack 211 has a material stopping surface 214, which extends up and down and is arranged opposite to the material guiding surface 212 and the material dropping surface 213. The above arrangement configures the unloading rack group 203 into a unloading rack 210 and a material blocking rack 211 that enclose a material storage channel 205. The unloading rack 210 has a material guiding surface 212 inclined from top to bottom toward the material blocking rack 211 and a material dropping surface 213 extending downward from the material guiding surface 212 to the unloading port 206, so that the pipes can be transported smoothly.

[0061] In the embodiment of the present invention, the material stopper 211 can move relative to the material unloading rack 210 to adjust the gap between the material stopper surface 214 and the material unloading surface 213. Specifically, when the material stopper 211 moves closer to the material unloading rack 210, the gap between the material stopper surface 214 and the material unloading surface 213 is reduced, and when the material stopper 211 moves away from the material unloading rack 210, the gap between the material stopper surface 214 and the material unloading surface 213 is increased. The above arrangement configures the material stopper 211 to be able to move relative to the material unloading rack 210 to adjust the gap between the material stopper surface 214 and the material unloading surface 213, so that the material storage channel 205 can adapt to pipes with different apertures, with good adaptability and flexible use.

[0062] In the embodiment of the present invention, the unloading rack 210 is provided with a pushing arm 215, which can rotate with its connection with the unloading rack 210 as the axis to protrude or withdraw from the material guide surface 212, and when the pushing arm 215 protrudes the material guide surface 212, the pipe fittings are moved toward the material stop rack 211 or are restricted from moving toward the material stop rack 211.
