For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0066] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0067] Example:

[0068] like Figure 1 As shown, an embodiment of the present application discloses a pipe cold drawing device for producing a tee pipe with multiple branches, and its specific structure includes: a frame 1, a vertical driving mechanism 2, a driving rod 3, a pipe fixing mechanism 4 and a conveying mechanism 5.

[0069] The frame 1 has a workbench 11 , and legs are arranged around the bottom of the workbench 11 for stably placing it on a work site to support other components.

[0070] The vertical driving mechanism 2 is installed on the top of the workbench 11 and is used to drive the driving rod 3 to move vertically.

[0071] The driving rod 3 is vertically arranged, one end of which is transmission-connected to the vertical driving mechanism 2, and the other end of which passes through the workbench 11 and is detachably connected to the cold drawing die, so as to drive the cold drawing die to stretch and expand the main pipe.

[0072] The pipeline fixing mechanism 4 includes a clamping pipe 41 and a concave bracket 42 .

[0073] Specifically, the clamping tube 41 is vertically arranged and sleeved outside the driving rod 3, the top end of the clamping tube 41 is detachably connected to the bottom of the workbench 11, and the bottom end is provided with an arc groove 411 adapted to the pipeline.

[0074] Specifically, the concave bracket 42 is opened upward and arranged below the clamping tube 41 ; an arc chamfer is provided on the inner top of the concave bracket 42 to increase the contact area when supporting the main pipe, thereby reducing stress concentration.

[0075] The conveying mechanism 5 includes a vertical lifting module 51 and a horizontal conveying module 52 .

[0076] Specifically, the vertical lifting module 51 is used to drive the concave bracket 42 to move vertically; and the lateral conveying module 52 is used to drive the vertical lifting module 51 to move horizontally.

[0077] In the above technical scheme, during production, the main pipe is placed on the concave bracket 42 of the pipe fixing mechanism 4, and then the main pipe is moved laterally along the axial direction by the transverse conveying module 52 in the conveying mechanism 5, and then the main pipe is rotated circumferentially so that the position of the hole to be expanded corresponds to the driving rod 3, and then the concave bracket 42 is driven to rise by the vertical lifting module 51 in the conveying mechanism 5, so that the main pipe on the concave bracket 42 is lifted to engage with the arc groove 411 at the bottom of the clamping tube 41. At this time, the main pipe is clamped and fixed up and down to ensure stability during cold drawing, and at the same time, the bottom end of the driving rod 3 will extend into the hole to be expanded; therefore, after the cold drawing mold is installed on the bottom end of the driving rod 3 in the main pipe, the vertical driving mechanism 2 can be used to drive the driving rod 3, and the driving rod 3 pulls the cold drawing mold to cold-draw and expand the hole to be expanded on the main pipe.

[0078] It should be noted that, by disassembling and replacing the clamping tube 41 , the curvature of the arc-shaped groove 411 can be adjusted, thereby being able to adapt to the use of cold-drawn main pipes with different diameters, thereby expanding the scope of application.

[0079] By lateral displacement of the main pipeline along the axial direction, circumferential rotation of the main pipeline and replacement of cold drawing dies of different sizes, cold drawing expansion can be performed on holes to be expanded in different positions, directions and diameters, thereby adapting to the production and manufacturing of pipelines with multiple branches on the main pipeline. This is convenient and practical, improves productivity and reduces production costs.

[0080] In some embodiments, Figure 2 As shown, in order to improve the cold drawing stability, the vertical drive mechanism 2 is further designed, which includes:

[0081] The first support plate 21 is installed at the top of the driving rod 3 and has a rectangular structure with good regularity. It is preferably connected to the driving rod 3 at the center to ensure force balance;

[0082] The support platform 22 is installed on the top of the workbench 11. The support platform 22 has a rectangular platform with legs arranged around the bottom of the platform for being stably placed on the workbench 11 to support other components.

[0083] The driving cylinder 23 has a cylinder rod arranged upward and a cylinder body installed on the top of the support platform 22. The driving cylinder 23 is preferably an oil cylinder, which has the advantages of strong bearing capacity and high driving force;

[0084] The second support plate 24 is installed at the top of the cylinder rod of the driving cylinder 23, has a rectangular structure, has good regularity, and is preferably located at the center of the top to ensure uniform force and improve movement stability;

[0085] A plurality of guide rods 25 are arranged around the driving cylinder 23, with the bottom connected to the first support plate 21 and the top passing through the support platform 22 and connected to the second support plate 24; there are four guide rods 25 and they are arranged at four corners to ensure uniform force; the two ends are respectively bolted to facilitate assembly and disassembly, and convenient production assembly; in addition, the support platform 3 is provided with a guide hole that matches it, so as to realize limit guiding.

[0086] When driven, the driving cylinder 23 pushes the second support plate 24 to rise, and the second support plate 24 pulls the first support plate 21 to rise synchronously through multiple guide rods 25. The first support plate 21 drives the driving rod 3 to rise, thereby driving the driving rod 3 to move vertically.

[0087] Through the above arrangement, uniform force is ensured, and the plurality of guide rods 3 are utilized to play a limiting and guiding role, thereby improving the stability of the cold drawing process and the regularity of the formed pipe mouth.

[0088] Preferably, the driving rod 3 is threadedly connected to the first support plate 21, so that the driving rod 3 can be disassembled, assembled and replaced, so that driving rods 3 of different diameters can be used, which not only avoids the situation where the diameter is too large and cannot be inserted into the hole to be expanded, but also avoids the situation where the diameter is too small, the bearing capacity is low, and it is easy to break. It meets the use of holes of different diameters to be expanded and has a good use effect.

[0089] In some embodiments, Figure 5 and Figure 6 As shown, a mounting plate 43 is provided on the outer peripheral fixed sleeve of the top of the clamping tube 41, and a plurality of mounting through holes 431 are provided on the mounting plate 43, and a plurality of threaded holes 111 are provided on the bottom of the workbench 11;

[0090] The mounting through holes 431 correspond to the threaded holes 111 in a one-to-one manner, and are used to realize the bolt connection between the mounting plate 43 and the workbench 11 .

[0091] The mounting plate 43 can be fixed to the bottom plate of the workbench 11 by passing bolts through the mounting through holes 431 and threadedly connected to the threaded holes 111 , thereby completing the installation of the clamping tube 41 .

[0092] The above design can position the clamping tube 41 during installation, improve installation efficiency, and facilitate disassembly and replacement of the clamping tube 41 while ensuring stable installation.

[0093] In some embodiments, Figure 3 As shown, in order to improve the conveying stability, the transverse conveying module 52 is further designed, which includes:

[0094] The frame 521 is an I-shaped structure;

[0095] The four track wheels 522 are mounted on the four corners of the vehicle frame 521 in a one-to-one correspondence.

[0096] Through the above design, the transverse conveying module 52 can move laterally on the two guide rails, its movement is highly stable, and it is easy to adjust and operate, which is convenient for practical application.

[0097] Based on the above embodiments, Figure 4 As shown, in order to facilitate manipulation, the vertical lifting module 51 is further designed to include: a concave steel 511 and two lifting components 512 .

[0098] Specifically, the concave steel 511 is opened downward and is disposed on the bottom surface of the concave bracket 42 .

[0099] Specifically, two lifting assemblies 512 are respectively installed at both ends of the frame 521 to lift both ends of the concave steel 511 .

[0100] Exemplarily, the lifting assembly 512 includes:

[0101] The lifting cylinder 512a has a cylinder rod arranged upward, and the cylinder body is installed at the end of the frame 521. The lifting cylinder 512a is preferably a pneumatic cylinder for easy control, but is not limited thereto, and can also be a servo electric cylinder, without specific limitation;

[0102] The lifting plate 512b is installed on the top of the cylinder rod of the lifting cylinder 512a, and is used to support the end of the concave steel 511; the bottom plate of the lifting plate 512b is provided with a fixing sleeve, and the fixing sleeve is sleeved on the cylinder rod of the lifting cylinder 512a, thereby improving the stability of the connection;

[0103] Two limit blocks 512c are arranged on the lifting plate 512b and fit with the two sides of the concave steel 511, and are used to limit the concave steel 511 to the left and right, thereby ensuring stability during operation.

[0104] When lifting, the lifting cylinder 512a is started, and the lifting cylinder 512a lifts the end of the concave steel 511 through the lifting plate 512b. The two lifting components 512 cooperate with each other to make the concave steel 511 rise stably, thereby driving the concave bracket 42 to rise together.

[0105] Through the above design, the concave bracket 42 can be stably driven to perform lifting movements, which is easy to operate, saves time and effort, and improves production efficiency.

[0106] Based on the above embodiments, Figure 4 As shown, in order to improve applicability, the vertical lifting module 51 also includes: two support components 513, which are respectively installed at both ends of the frame 521, and are used to support and adjust the height of the cylinder body of the lifting cylinder 512a.

[0107] It should be noted that, due to the limitation of the stroke of the lifting cylinder 512a, the range of the lifting and lowering movement of the concave bracket 42 is limited, resulting in a limitation on the size of the pipe that the pipe fixing mechanism 4 can adapt to.

[0108] Therefore, by providing the support assembly 513, the height of the lifting cylinder 512a can be adjusted up and down, thereby adjusting the height of the concave bracket 42, thereby improving applicability.

[0109] Specifically, Figure 4 and Figure 7 As shown, the support assembly 513 includes:

[0110] Two hollow tubes 513a are vertically mounted at the end of the frame 521 and arranged on both sides of the lifting cylinder 512a. They are preferably square tubes with good regularity.

[0111] Two adjusting columns 513b are inserted into the hollow tube 513a one by one, and the top ends extend out of the hollow tube 513a, and the shapes correspond to the hollow tube 513a;

[0112] Two fixing plates 513c are mounted on the top of the adjusting column 513b in a one-to-one correspondence;

[0113] The limiting plate 513d is fixedly mounted on the cylinder body of the lifting cylinder 512a, and its two ends are detachably connected to the two fixing plates 513c respectively;

[0114] The two locking structures are used to lock and fix the adjusting column 513b and the corresponding hollow tube 513a after moving the adjusting column 513b up and down to a suitable height.

[0115] It should be noted that the fixing plate 513c and the limiting plate 513d are detachably connected, preferably by bolt connection, which has a simple structure and a stable connection, and is convenient for disassembly and assembly of the lifting cylinder 512a and later maintenance.

[0116] Through the above design, the cylinder body of the lifting cylinder 512a can be supported on the left and right to ensure stability, and can be guided and limited on the left and right to avoid the uneven top surface caused by adjustment, thereby improving the stability and portability of the adjustment.

[0117] In this embodiment, if Figure 7 As shown, multiple groups of first through holes are vertically spaced apart on the hollow tube 513a, each group of first through holes has two holes and are arranged on both sides of the hollow tube 513a, and second through holes 513g are arranged on the adjustment column 513b, and both ends of the second through holes 513g can be aligned with any group of first through holes.

[0118] Specifically, in this embodiment, two groups of first through holes are provided, but it is not limited thereto, and it may also be three groups, four groups or more, which is not specifically limited.

[0119] Specifically, Figure 4 As shown, the locking structure includes:

[0120] A plurality of nuts 513e are installed outside the first through hole in a one-to-one correspondence;

[0121] The bolt 513f can pass through the first through hole and the second through hole 513g and be threadedly connected with the nut 513e.

[0122] During adjustment, the adjusting column 513b is moved up and down so that the second through hole 513g is aligned with a group of first through holes on the hollow tube 513a, and then the bolt 513f is passed through and tightened with the nut 513e, so that the adjusting column 513b and the hollow tube 513a are locked.

[0123] Through the above design, the locking of the adjustment column 513b and the hollow tube 513a can be completed conveniently and simply, and its bearing capacity is strong and the structural stability is high, which ensures the use effect of the device.
