Moreover, the large number of processing steps and the large number of required devices also lead to a high possibility of defective products. At the same time, the equipment cost of the pipe processing device is large, and different steps may require different devices, which is not conducive to the production cost of the enterprise.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0072] The technical solution of the present solution will be further described below with reference to the drawings through specific embodiments.

[0073] A forming device for a pipe, comprising: a pipe wall processing part 1 and an end processing part 2;

[0074] The pipe wall processing part 1 is used for performing hole processing on the side wall of the pipe 9;

[0075] The end processing part 2 includes: a second pipe support part 21, an end former 22 and an end heating column 23;

[0076] The second pipe support part 21 is used for fixing the pipe transferred from the pipe wall processing part 1; the end former 22 includes: a punch split plate 221 and a forming driver 220;

[0077] A plurality of the punch split plates 221 are annularly distributed, and an inner ring of the punch split plate 221 forms a punch through-port 228 in a separated state; the forming driver 220 drives the inner ring of the punch split plate 221 to move towards the punch through-port 228, so that the inner rings of the plurality of punch split plates 221 are close to each other in a tightened state and form a punch groove 229 with a gradually decreasing inner diameter;

[0078] When a plurality of the punch split plates 221 are in a separated state, after the end heating column 23 passes through the punch through-port 228, it extends into the end of the pipe, and the end heating column 23 is used for heating the pipe wall of the pipe;

[0079] When a plurality of the punch split plates 221 are in a tightened state, the second pipe support part 21 is used for driving one end of the pipe to press against the punch groove 229, so that one end of the pipe extending into the punch groove 229 is sealed and formed.

[0080] This solution provides a forming device for pipes. It forms and processes pipes through a pipe wall processing part 1 and an end processing part 2. It can adjust multiple press head split plates 221 to a separated state and a close-fitting state, which is convenient for adjusting the end heating column 23 to enter the pipe and the sealing forming of one end of the pipe itself, solves the problem of cumbersome and complex pipe forming steps in the prior art, and improves the efficiency of pipe forming.

[0081] Specifically, as Figure 1 and Figure 2 , the pipe wall processing part 1 is used for hole processing on the side wall of the pipe, and it can be replaced by a well-known drilling mechanism; after the pipe wall processing part 1 finishes the hole processing, it can transfer the pipe to the end processing part 2; the pipe is placed on the second pipeline support part 21; the press head split plates 221 are in a separated state, a gap is formed between multiple press head split plates 221, and a press head passing port 228 is formed at one end of the inner circle of the press head split plates 221, as Figure 3 ; at this time, the end heating column 23 can pass through the press head passing port 228 and extend into the end of the pipe to heat the end of the pipe, which is convenient for subsequent processing; after that, the forming driver 220 drives multiple press head split plates 221 to move in the direction of the press head passing port 228, and the diameter of the press head passing port 228 becomes smaller and smaller; one end of multiple press head split plates 221 abuts against each other to form a concave press head groove 229, as Figure 4 ; after that, only need to drive the second pipeline support part 21 to move, drive the pipe to move in the direction of the press head groove 229, as Figure 4 ; one end of the pipe abuts against the inner wall of the press head groove 229. Since this end has been heated by the end heating column 23, this end is easy to process; the shape of the press head groove 229 can be designed according to the processing requirements of the pipe. The diameter of the press head groove 229 gradually decreases from the outside to the inside. When one end of the pipe extends into the press head groove 229, the inner wall of the press head groove 229 gradually tightens one end of the pipe, that is, guides one end of the pipe to tighten towards the central axis, and a bullet head structure 91 is formed at one end of the pipe; at the same time, grooves or protrusions can be designed on the inner wall of the press head groove 229 to process a specific structure on the outside of the pipe port, such as a reinforcing rib 93, etc.

[0082] Among them, the forming driver 220 can be a well-known mechanism with a driving function. For example, in one embodiment, the forming driver 220 is a cylinder, and the cylinder drives the press head split plates 221 to move towards the press head passing port 228; for example, in one embodiment, the forming driver 220 is an endless belt. Place multiple press head split plates 221 inside the endless belt and tighten the inner diameter of the endless belt, then the press head split plates 221 can be controlled to be adjusted to a separated state and a close-fitting state.

[0083] The movement of the second pipeline support part 21 can be realized by a well-known driving mechanism, such as a conveyor belt, a transfer cart, or a combination of a motor and a lead screw, etc.

[0084] Preferably, the pipe wall processing part 1 includes: a first pipe support part 11, a pipe wall heating column 12, and a pipe wall drill 13;

[0085] The first pipe support part 11 is used to fix the pipe; the pipe wall heating column 12 is telescopically retractable, and the pipe wall heating column 12 is used to axially extend one end into the interior of the pipe and heat the pipe wall; the pipe wall drills 13 are distributed on the side of the moving direction of the pipe wall heating column 12, and the pipe wall drills 13 are used to perform hole processing on the wall surface of the pipe.

[0086] Such as Figure 1 and Figure 2 , the pipe is pre-placed on the first pipe support part 11 and then transferred from the first pipe support part 11 to the second pipe support part 21; the pipe wall heating column 12 can extend into the pipe to heat the position where the hole is drilled in the pipe. The pipe wall drills 13 perform hole processing on the wall surface of the pipe to form a water inlet hole, a water outlet hole, or other functional holes on the side wall of the pipe.

[0087] The movement of the first pipe support part 11 can be realized by a known driving mechanism, such as a conveyor belt, a transfer cart, or a combination of a motor and a lead screw, etc.

[0088] More preferably, the pipe wall processing part 1 includes: a blowing mechanism 14;

[0089] The end heating column 23 has a through-hole structure; the two end heating columns 23 respectively extend into the two ends of the pipe; one end of one of the end heating columns 23 is communicated with the air outlet end of the blowing mechanism 14, and the other end of this end heating column 23 is used to extend into one end of the pipe;

[0090] The other end of the other end heating column 23 is used to extend into the other end of the pipe, and the inner side of the other end of this end heating column 23 is communicated with the outer side.

[0091] During the drilling process, some waste chips can enter the interior of the pipe through the drilled holes, so the end heating columns 23 can be extended into the interior of the pipe before and after drilling; before and after drilling, the end heating columns 23 extend into the pipe. On the one hand, the pipe can be heated, and on the other hand, the blowing mechanism 14 can be started; such as Figure 2 , the blowing mechanism 14 outputs air flow to the through-hole structure end heating column 23 to discharge the waste chips from the end heating column 23 at one end of the pipe through between the two ends of the pipe and then output from the end heating column 23 at the other end of the pipe, realizing the function of discharging waste chips. The blowing mechanism 14 is a known mechanism with an air output function, such as a hair dryer.

[0092] Preferably, the pipe wall processing part 1 includes: an angle driver 15;

[0093] The output end of the angle driver 15 is connected to the pipe wall heating column 12 and is used to drive the pipe wall heating column 12 to rotate.

[0094] Such as Figure 2 , the output end of the angle driver 15 can rotate to drive the pipe wall heating column 12 to rotate; the pipe wall drill bit 13 performs hole processing on the pipe wall of the pipe, specifically, drilling along the length direction of the pipe; when the pipe wall heating column 12 extends into the pipe, the first pipe support portion 11 can release the clamping of the pipe, and the pipe wall heating column 12 rotates to drive the pipe to rotate, so that the originally processed hole deviates from the pipe wall drill bit 13, and the pipe wall drill bit 13 can perform drilling on other positions of the pipe, thereby realizing drilling at multiple positions on the pipe body in the pipe; at the same time, since the pipe wall heating column 12 has a heating function, the pipe can be slightly heated by the pipe wall heating column 12 for a period of time, so that the pipe adheres slightly to the pipe wall heating column 12, facilitating the synchronous rotation of the pipe wall heating column 12 and the pipe.

[0095] Among them, the angle driver 15 can be driven by a synchronous belt. A driving wheel 151 is installed at the output end of the angle driver 15, and a driven wheel 152 is coaxially installed on the pipe wall heating column 12. The synchronous belt 153 synchronously connects the driving wheel and the driven wheel, thereby realizing the rotation of the pipe wall heating column 12.

[0096] Preferably, the end former 22 includes: a forming circular shell 222, a forming cover 223 and a return spring 224;

[0097] The forming circular shell 222 is provided with a forming circular groove 2221; a plurality of the press head dividing plates 221 are distributed around the press head through port 228 as the center in the forming circular groove 2221; one end of the return spring 224 is connected to the press head dividing plate 221, and the other end is connected to the inner wall of the forming circular groove 2221; the press head dividing plate 221 is provided with a driven inclined surface 2211; the forming cover 223 is provided with a driving inclined surface 2232; the forming cover 223 is movably covered on the notch of the forming circular groove 2221 in a returnable manner, and the driving inclined surface 2232 is attached to the driven inclined surface 2211; the driving inclined surface 2232 drives the driven inclined surface 2211 to move towards the press head through port 228, so that one ends of the plurality of press head dividing plates 221 form the press head groove 229 in a tightly attached state.

[0098] For the driving part of the indenter splitting plate 221, in one embodiment, the forming cover 223 is movably covered on the forming circular shell 222, that is, the forming cover 223 can approach and move away from the forming circular shell 222; thus, during the movement of the forming cover 223, the driving inclined surface 2232 of the forming cover 223 can adhere to the driven inclined surface 2211, and when the forming cover 223 approaches the forming circular shell 222, the driving inclined surface 2232 drives the driven inclined surface 2211 to move, driving the indenter splitting plate 221 to move towards the indenter passing port 228 and gradually compressing the return spring 224 until the inner diameter of the indenter passing port 228 gradually disappears; when the inner circles of multiple indenter splitting plates 221 abut against each other, the indenter groove 229 is finally formed; and since one end of the return spring 224 is connected to the indenter splitting plate 221 and the other end is connected to the inner wall of the forming circular groove 2221, at this time the return spring 224 is in a compressed state, when the forming cover 223 resets to move away from the forming circular shell 222, multiple indenter splitting plates 221 will automatically reset along with the elastic recovery of the return spring 224. Thus, the indenter splitting plate 221 can realize automatic switching between the separated state and the close state.

[0099] Among them, the relative movement between the forming cover 223 and the forming circular shell 222 can be realized by a mechanism known to have a driving function, such as a cylinder, a moving trolley, a conveyor belt, or a combination of a motor and a lead screw. It only needs to connect this mechanism to the forming cover 223 and / or the forming circular shell 222 to realize driving its linear movement. For example, in the figure, a cylinder is used to drive the forming cover 223 to move linearly. At the same time, to enable the forming cover 223 and the forming circular shell 222 to realize relative linear movement, a guiding hole 2231 can be provided between the forming cover 223 and the forming circular shell 222, and a guiding rod 227 is coaxially installed in the guiding holes 2231 of both.

[0100] Preferably, it further includes: a material conveying part 3;

[0101] The pipe wall processing part 1 and the end processing part 2 are arranged in sequence along the conveying direction of the pipe;

[0102] The pipe wall processing part 1 includes: a first pipe supporting part 11; the first pipe supporting part 11 is used to fix the pipe;

[0103] The material conveying part 3 includes: a material conveying inclined plate 31, a material conveying bracket 32, a material conveying manipulator 33, and a material blocking lifter 34;

[0104] The material transfer bracket 32 is provided with a support opening 321 for placing the pipe; the material transfer inclined plate 31 is inclined, and its lower end is aligned with the support opening 321; the output end of the material blocking lifter 34 can move close to and away from the material transfer inclined plate 31; when the output end of the material blocking lifter 34 is close to the material transfer inclined plate 31, the pipe is limited to the material transfer inclined plate 31; when the output end of the material blocking lifter 34 is away from the material transfer inclined plate 31, the material transfer inclined plate 31 guides the pipe to the support opening 321; the material transfer manipulator 33 is used to sequentially transfer the pipe from the support opening 321 to the first pipeline support part 11 and the second pipeline support part 21.

[0105] In this solution, the pipe can be placed on the material transfer inclined plate 31 manually or mechanically; in the initial state, the fixed end of the material blocking lifter 34 can be connected to the material transfer inclined plate 31, and the output end of the material blocking lifter 34 is close to the material transfer inclined plate 31. The distance between the output end and the material transfer inclined plate 31 is less than the outer diameter of the pipe. Therefore, the pipe cannot pass through the output end and fall, and the pipe is limited to the material transfer inclined plate 31. When the output end of the material blocking lifter 34 rises, the pipe can fall to the support opening 321 of the material transfer bracket 32 under the action of gravity; the support opening 321 can facilitate the subsequent transfer of the material transfer manipulator 33 to the first pipeline support part 11 and then from the first pipeline support part 11 to the second pipeline support part 21; thus, by adopting the above feeding method, this solution can achieve that only by driving the output end of the material blocking lifter 34 to rise and fall, the pipe can be automatically placed at the support opening 321 of the material transfer bracket 32. When the pipe falls along the material transfer inclined plate 31, the pipe wall rubs against the material transfer inclined plate 31 and falls to the support opening 321 of the bracket under the action of gravity. The pipe wall will generate a certain vibration, which can clean the impurities on the pipe wall, reduce the influence on drilling, and facilitate the impurity removal and discharge of the subsequent blowing mechanism 14.

[0106] In one of the embodiments, the end face former 24 cooperates with the end former 22 to form at one end of the pipe according to the groove shape of the pressing head groove 229, and a support table structure 92 is formed at the other end of the pipe according to the end face pressing head 243.

[0107] Specifically:

[0108] The end processing part 2 includes: an end face former 24;

[0109] The end face former 24 is located at one end of the pipe, and the end former 22 is located at the other end of the pipe;

[0110] The end face former 24 includes: a male end face pressing clamp 241, a female end face pressing clamp 242, and an end face pressing head 243;

[0111] The male end-face pressing clamp 241 and the female end-face pressing clamp 242 are movably abutted against each other, and an end-face forming opening 240 for accommodating the pipe is formed therebetween; one end of the end-face forming opening 240 is provided with an end-face step 244 at the pipe orifice; the end-face pressing head 243 moves to be linearly aligned with the end-face forming opening 240, and presses the pipe orifice of the pipe against the end-face step 244, so that the pipe orifice of the pipe is sealed according to the shape of the end-face forming opening 240.

[0112] The male end-face pressing clamp 241 and the female end-face pressing clamp 242 can move towards each other, which is realized by a mechanism known to have a linear movement driving function, such as Figure 2 and Figure 7 a cylinder is used to drive the linear movement of the male end-face pressing clamp 241 and the female end-face pressing clamp 242 in [relevant reference]; when the male end-face pressing clamp 241 and the female end-face pressing clamp 242 move towards each other, the end-face forming opening 240 formed therebetween can clamp the pipe to prevent deviation during the subsequent end-face forming of the pipe. The end heating column 23 can extend into the end of the pipe to heat the end of the pipe; the end-face pressing head 243 moves to be horizontally aligned with the end-face forming opening 240 and presses one end of the pipe towards the end-face forming opening 240; at the same time, the end-face pressing head 243 can press the pipe towards the end-face step 244, seal one end of the pipe, and shape the end according to the shape of the end-face step 244, forming a support platform structure 92. For example, the inner diameter of one end of the end-face forming opening 240 outside the end-face step 244 is the largest, and the inner diameter from within the end-face step 244 to the other end is smaller than the inner diameter outside the end-face step 244; thus, a support platform structure 92 is finally formed at one end of the pipe, and the support platform structure 92 is located outside the end-face step 244, so the outer diameter of the support platform structure 92 is larger than the outer diameter of the pipe 9.

[0113] In one embodiment, the end former 22 can cooperate with the circumferential pressing device 4 to place the pipe made by the end former 22 inside the metal pipe 8. Specifically:

[0114] An assembling device for a pipe, comprising: a circumferential pressing device 4 and the above-mentioned pipe forming device;

[0115] The circumferential pressing device 4 includes: hydraulic split plates 41, a hydraulic frame 42 and a hydraulic driver;

[0116] A plurality of the hydraulic split plates 41 are distributed around the center in the hydraulic frame 42, and a hydraulic port 43 for accommodating the metal pipe 8 is provided at the center;

[0117] When adjacent two of the hydraulic split plates 41 are separated, the inner diameter of the hydraulic port 43 is the largest;

[0118] When the hydraulic driver drives the multiple hydraulic splitting plates 41 to be sequentially and resetably attached together, the inner diameter of the hydraulic port 43 is the smallest, and the hydraulic port 43 fixes the metal pipe 8; the hydraulic splitting plate 41 is provided with a hydraulic bump 44 in the hydraulic port 43.

[0119] As Figure 8 and Figure 9 , place the metal pipe 8 in the hydraulic port 43, and place the pipe processed by the end former 22 of this solution in the metal pipe; in the initial state, the hydraulic splitting plates 41 are distributed around the hydraulic frame 42, as Figure 8 ; this solution can drive the hydraulic splitting plates 41 through a hydraulic driver to move the multiple hydraulic splitting plates 41 towards the hydraulic port 43, gradually tighten the hydraulic port 43, and finally make one end of the hydraulic splitting plates 41 abut against each other. The inner diameter of the hydraulic port 43 is the smallest, and then the metal pipe can be pressed by the hydraulic splitting plates 41, as Figure 9 ; there is a hydraulic bump 44 in the hydraulic port 43. When the inner wall of the hydraulic port 43 presses the metal pipe, the hydraulic bump 44 presses the outer wall of the metal pipe to be concave, so a convex head is formed inside the metal pipe, and this convex head presses the pipe, thereby improving the connection tightness between the pipe and the metal pipe. The hydraulic driver is a known mechanism with a driving function. For example, in one embodiment, the hydraulic driver is a cylinder, and the cylinder drives the hydraulic splitting plate 41 to move towards the hydraulic port 43 to tighten the hydraulic port 43; for example, in one embodiment, the hydraulic driver is an endless belt. Place the multiple hydraulic splitting plates 41 inside the endless belt, and mechanically drive the inner diameter of the endless belt to tighten, then the inner diameter size of the hydraulic port 43 can be controlled. In the optimal embodiment, as Figure 8 and Figure 9 , the hydraulic driver is a circumferential hydraulic press. For example, in one embodiment, the inner diameter of the open end of the hydraulic frame 42 is larger than the inner diameter of the other open end. The hydraulic driver drives the hydraulic splitting plate 41 to move along the length direction of the hydraulic frame 42, driving the hydraulic splitting plate 41 to move to the end with a larger diameter, and then separating the hydraulic splitting plates 41; the hydraulic driver drives the hydraulic splitting plate 41 to move along the length direction of the hydraulic frame 42, driving the hydraulic splitting plate 41 to move to the end with a smaller diameter, and then contracting the hydraulic splitting plates 41 to press the metal pipe. Of course, if necessary, before the hydraulic bump 44 presses the metal pipe, a heating column can also be used to heat the pipe wall of the pipe inside the metal pipe to facilitate the fit between the convex head and the pipe wall.
