Description

Technical Field

[0001] This utility model relates to the field of pipe manufacturing technology, and in particular to a die and mandrel structure for pipe manufacturing. Background Technology

[0002] In pipe manufacturing, the die and mandrel structures are crucial components, playing a key role in the pipe extrusion process. The die primarily controls the outer diameter of the pipe, ensuring the accuracy of its dimensions and shape. The mandrel, on the other hand, is the key component controlling the inner diameter of the pipe, ensuring a uniform and smooth inner wall through stable support. Furthermore, the design of both the die and mandrel typically includes components such as heating rings to maintain appropriate temperatures, ensuring good flowability and forming results during extrusion.

[0003] However, when using the die and mandrel in conjunction with other parts, the heating ring may sometimes be damaged due to long-term use or external factors and need to be replaced, but disassembly and assembly are inconvenient. This results in more time being spent on disassembly and assembly, which reduces the convenience of subsequent device maintenance. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a die and mandrel structure for pipe production.

[0005] This utility model is achieved by the following technical solution: a die and mandrel structure for pipe production, including a mounting base, a mandrel threadedly connected to the inner wall of the mounting base, an adjusting screw threadedly connected to the inner wall of the mounting base, a pressure cap threadedly connected to the surface of the adjusting screw, and a connecting component disposed inside the pressure cap;

[0006] The connecting assembly includes a die, the surface of which has a mounting groove. A heating ring is slidably connected to the surface of the mounting groove. A connecting pad is fixedly connected to the right end of the heating ring. A mounting bracket is fixedly connected to the right end of the die. A rotating shaft is rotatably connected to the inner wall of the mounting bracket. A limit plate is fixedly connected to the surface of the rotating shaft. A turbine is fixedly connected to the surface of the rotating shaft. A rotating frame is rotatably connected to the inner wall of the mounting bracket. A threaded frame is fixedly connected to the left end of the rotating frame.

[0007] By using the above technical solution, and employing a rotating frame to drive the limiting plate to rotate while fixing the mounting bracket and other parts on the right end of the die, the heating ring can be easily installed onto the die surface, making the subsequent use of the device more convenient and improving the overall practicality of the device.

[0008] As a further improvement to the above solution, the surface of the threaded frame is provided with a volute thread, and the surface of the threaded frame engages with the side end of the turbine.

[0009] The above technical solution provides a stable connection for the subsequent rotating frame to drive the threaded frame to drive the turbine rotation, making the subsequent operation of driving the limit plate to rotate more stable and convenient, and improving the subsequent practicality of the device.

[0010] As a further improvement to the above scheme, the number of rotating shafts is four, and the four rotating shafts are evenly distributed around the mounting frame.

[0011] By using the above technical solution, the design of using multiple rotating shafts to simultaneously drive the limiting rotating plate and the connecting pad (504) for connection and limiting achieves the purpose of making the subsequent installation of the heating ring more stable and improving the convenience of subsequent use of the device.

[0012] As a further improvement to the above solution, the inner wall of the connecting pad is engaged with the surface of the limiting rotating plate.

[0013] As a further improvement to the above solution, the surface of the limiting rotating plate is rotatably connected to the inner wall of the mounting frame.

[0014] As a further improvement to the above solution, the left end of the pressure cap contacts the right end of the mounting base.

[0015] As a further improvement to the above solution, the surface of the die is engaged with the inner wall of the gland, and the die is located on the surface of the mandrel.

[0016] The above technical solution makes the installation of subsequent parts such as the die more convenient and improves the ease of use of the subsequent device.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention uses a rotating frame to drive a threaded frame to rotate, which in turn drives a turbine meshing with the threaded frame to rotate. Simultaneously, this drives a rotating shaft and a limiting plate to rotate, allowing the limiting plate to be inserted into the mounting frame. At this point, the heating ring, along with the connecting pad, can be fitted onto the surface of the mounting groove. After the heating ring is installed, the rotating frame is rotated in the opposite direction to drive the limiting plate back, causing it to engage with the inner wall of the connecting pad, thus limiting the position of the heating ring. This completes the convenient installation of the heating ring, allowing for easy removal from the die in case of a malfunction, further improving the overall practicality of the device.

[0019] This invention installs the mandrel by rotating it to the inner wall of the mounting base connected to the production equipment. Then, the die is inserted onto the surface of the mandrel. After the die is placed, the pressure cap is placed over the surface of the die and fitted into the mounting base. The adjusting screw on the inner wall of the pressure cap is then rotated to connect the adjusting screw to the mounting base, thus fixing the pressure cap to the mounting base. Simultaneously, the pressure cap fixes the position of the die. This completes the installation of the die and mandrel, allowing for convenient disassembly and replacement of the die and mandrel when cleaning or replacement is needed. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-5 The pipe production die and mandrel structure of this embodiment includes a mounting base 1, a mandrel 2 threadedly connected to the inner wall of the mounting base 1, an adjusting screw 3 threadedly connected to the inner wall of the mounting base 1, a pressure cap 4 threadedly connected to the surface of the adjusting screw 3, and a connecting component 5 disposed inside the pressure cap 4.

[0030] The connecting assembly 5 includes a die 501. A mounting groove 502 is formed on the surface of the die 501. A heating ring 503 is slidably connected to the surface of the mounting groove 502. A connecting pad 504 is fixedly connected to the right end of the heating ring 503. A mounting bracket 505 is fixedly connected to the right end of the die 501. A rotating shaft 506 is rotatably connected to the inner wall of the mounting bracket 505. A limiting rotating plate 507 is fixedly connected to the surface of the rotating shaft 506. A turbine 508 is fixedly connected to the surface of the rotating shaft 506. A rotating frame 509 is rotatably connected to the inner wall of the mounting bracket 505. A threaded bracket 510 is fixedly connected to the left end of the rotating frame 509. This design, which uses the mounting bracket 505 and other parts fixed to the right end of the die 501 while simultaneously using the rotating frame 509 to drive the limiting rotating plate 507 to rotate, allows for convenient installation of the heating ring 503 onto the surface of the die 501. This makes subsequent use of the device more convenient and improves the overall practicality of the device.

[0031] The surface of the threaded bracket 510 is provided with a volute thread. The surface of the threaded bracket 510 meshes with the side end of the turbine 508, providing a stable connection for the subsequent rotating bracket 509 to drive the threaded bracket 510 to drive the turbine 508 to rotate. This makes the subsequent operation of driving the limit plate 507 to rotate more stable and convenient, and improves the subsequent practicality of the device.

[0032] There are four rotating shafts 506, which are evenly distributed around the mounting bracket 505.

[0033] The inner wall of the connecting pad 504 is engaged with the surface of the limiting rotating plate 507.

[0034] The surface of the limiting rotating plate 507 is rotatably connected to the inner wall of the mounting bracket 505.

[0035] The left end of the pressure cap 4 contacts the right end of the mounting base 1.

[0036] The surface of the die 501 is engaged with the inner wall of the gland 4, and the die 501 is located on the surface of the mandrel 2.

[0037] The implementation principle of the die and mandrel structure for pipe production in this embodiment is as follows: When using the device, the mandrel 2 is first rotated to the inner wall of the mounting base 1 connected to the production equipment to install the mandrel 2. Then, the die 501 is inserted into the surface of the mandrel 2. After the die 501 is placed, the pressure cap 4 is put onto the surface of the die 501 and made to fit against the mounting base 1. Then, the adjusting screw 3 on the inner wall of the pressure cap 4 is rotated to connect the adjusting screw 3 to the mounting base 1, thereby fixing the pressure cap 4 and the mounting base 1. At the same time, the pressure cap 4 fixes the position of the die 501. After the die 501 and the pressure cap 4 are installed, the rotating frame 509 is rotated to drive the threaded frame 510 to rotate, thereby driving the turbine 508 meshing with the threaded frame 510 to rotate, and at the same time driving the rotating shaft. Rotating the limiting rotating plate 507 with the 506 allows the limiting rotating plate 507 to be rotated into the mounting bracket 505. At this point, the heating ring 503, along with the connecting pad 504, can be fitted onto the surface of the mounting groove 502. After the heating ring 503 is installed, the rotating bracket 509 is rotated in the opposite direction to drive the limiting rotating plate 507 back, so that it can be locked into the inner wall of the connecting pad 504, thereby limiting the position of the heating ring 503. This completes the convenient installation of the heating ring 503. By using the design of fixing the mounting bracket 505 and other parts on the right end of the die 501 and using the rotating bracket 509 to drive the limiting rotating plate 507 to rotate, the device achieves the purpose of conveniently installing the heating ring 503 onto the surface of the die 501, making the subsequent use of the device more convenient and improving the overall practicality of the device.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
