[0001] This utility model belongs to the field of PCCP pipe processing, and specifically relates to a PCCP pipe expansion and rounding machine. Background Technology
[0002] Prestressed concrete cylinder pipe refers to a water pipe made by winding circumferential prestressed steel wires around a high-strength concrete core with a steel cylinder, and then spraying a dense cement mortar protective layer on it. Nowadays, PCCP pipe processing requires multiple processes, one of which is the expansion machine.
[0003] When processing pipe fittings, the existing expansion rounding machine cannot flexibly and accurately control and adjust the overall processing size. This requires manual measurement by the staff, and there is a certain error in the manual measurement process, which affects the processing effect of the machine itself. Utility Model Content
[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0005] To address the problems mentioned in the background section, the present invention adopts the following technical solution.
[0006] A PCCP pipe expansion and rounding machine includes an expansion and rounding machine body, a pushing component, and a mounting frame. The surface of the expansion and rounding machine body is equipped with multiple sets of pushing components for processing the workpiece. Multiple sets of mounting frames are installed inside the expansion and rounding machine body. The mounting frame is equipped with a positioning mechanism for controlling the movement distance of the pushing component. The positioning mechanism includes a blocking component and an extension slot. Multiple sets of extension slots are equally spaced inside the mounting frame, and the blocking component is installed inside the extension slot.
[0007] As a preferred technical solution of this utility model, the blocking assembly includes a blocking plate, a limiting block and a spring assembly. The blocking plate is slidably installed in the extension groove, the limiting block is installed at the bottom end of the blocking plate, and the spring assembly is symmetrically arranged at the top end of the limiting block.
[0008] As a preferred technical solution of this utility model, the positioning mechanism further includes a moving groove, an extrusion component and a drive motor. The mounting frame has a moving groove that communicates with the extension groove inside. The extrusion component is installed inside the moving groove, and the drive motor is fixedly installed on the side of the mounting frame.
[0009] As a preferred technical solution of this utility model, the extrusion assembly includes a lead screw, a guide rod, a moving end, and an extrusion block. The lead screw is rotatably installed inside the moving groove, the guide rod is fixedly installed inside the moving groove, the moving end is threadedly installed outside the lead screw, the moving end is slidably connected to the guide rod, and the extrusion block is fixedly installed on the surface of the moving end, and the extrusion block is in contact with the bottom end of the limiting block.
[0010] As a preferred embodiment of this utility model, the output end of the drive motor passes through the interior of the mounting bracket and is connected to the end of the lead screw.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.
[0025] Depend on Figure 1 As shown, it is a structural schematic diagram of the PCCP pipe expansion machine in this embodiment, including the expansion machine body 1, the pusher 2 and the mounting frame 4. The surface of the expansion machine body 1 is equipped with multiple sets of pushers 2 for processing the workpiece 3 to be processed. Multiple sets of mounting frames 4 are installed inside the expansion machine body 1. The mounting frame 4 is equipped with a positioning mechanism 5 for controlling the moving distance of the pusher 2.
[0026] In use, the workpiece 3 to be processed is placed on the upper surface of the body 1 of the expansion machine. Through the movement of the pusher 2 and the operation of the body 1 of the expansion machine, multiple sets of pushers 2 move outward at the same time, expanding the volume of the workpiece 3. At this time, the maximum movement distance of the pusher 2 is controlled by the operation of the positioning mechanism 5, ensuring that the movement distance of each set of pushers 2 is controlled, thus ensuring the accuracy of the overall processing of the body 1 of the expansion machine.
[0027] From the appendix Figure 3 As shown, it is a structural schematic diagram of the positioning mechanism 5 in this embodiment. The positioning mechanism 5 includes a blocking component 51 and an extension slot 52. Multiple sets of extension slots 52 are equidistantly provided inside the mounting frame 4, and the blocking component 51 is installed inside the extension slot 52.
[0028] During use, the position of a single blocking component 51 is adjusted by the operation of the blocking component 51 itself and in conjunction with other components in the positioning mechanism 5, so that the blocking component 51 extends through the extension groove 52 and protrudes on the upper surface of the body 1 of the expansion machine. When the pushing component 2 processes the workpiece 3, the pushing component 2 pushes the workpiece 3 to the target position and then contacts the blocking component 51, so as to stably control the processing distance of the pushing component 2.
[0029] From the appendix Figure 4 As shown, it is a structural schematic diagram of the blocking component 51 in this embodiment. The blocking component 51 includes a blocking plate 511, a limiting block 512 and a spring assembly 513. The blocking plate 511 is slidably installed in the extension groove 52, the limiting block 512 is installed at the bottom of the blocking plate 511, and the spring assembly 513 is symmetrically arranged at the top of the limiting block 512.
[0030] During use, the movement of the blocking plate 511 allows it to extend out of the extension groove 52, limiting and blocking the moving pusher 2 and the workpiece 3. The installation of the limiting block 512 limits the maximum movement distance of the blocking plate 511, preventing the blocking plate 511 from detaching from the extension groove 52. Subsequently, in conjunction with the spring assembly 513, the elastic force of the spring assembly 513 pushes the limiting block 512 and the blocking plate 511 into the extension groove 52, ensuring that the blocking plate 511 cannot extend out of the extension groove 52 without the cooperation of other components.
[0031] From the appendix Figure 3 As shown, it is a structural schematic diagram of the positioning mechanism 5 in this embodiment. The positioning mechanism 5 also includes a moving groove 53, a pressing component 54 and a drive motor 55. The mounting frame 4 has a moving groove 53 that communicates with the extension groove 52. The pressing component 54 is installed inside the moving groove 53, and the drive motor 55 is fixedly installed on the side of the mounting frame 4.
[0032] During use, the extrusion component 54 is activated inside the moving groove 53 by the operation of the drive motor 55, which extrudes the entire position of the blocking component 51, thereby limiting the movement of the subsequent pusher 2.
[0033] From the appendix Figure 4As shown, this is a schematic diagram of the extrusion assembly 54 in this embodiment. The extrusion assembly 54 includes a lead screw 541, a guide rod 542, a moving end 543, and an extrusion block 544. The lead screw 541 is rotatably installed inside the moving groove 53, the guide rod 542 is fixedly installed inside the moving groove 53, the moving end 543 is threadedly installed outside the lead screw 541, and the moving end 543 is slidably connected to the guide rod 542. The extrusion block 544 is fixedly installed on the surface of the moving end 543, and the extrusion block 544 is in contact with the bottom end of the limiting block 512.
[0034] During use, as the lead screw 541 rotates, the moving end 543 moves along the thread on the outside of the lead screw 541. When the moving end 543 moves, the guide rod 542 can limit the movement trajectory of the moving end 543 to ensure the stability of the moving end 543. Then, the moving end 543 drives the pressing block 544 to move smoothly and press the bottom end of the limiting block 512, so that the blocking plate 511 extends out of the extension groove 52, thereby limiting the maximum movement distance of the pushing member 2.
[0035] From the appendix Figure 4 As shown, the output end of the drive motor 55 passes through the interior of the mounting bracket 4 and is connected to the end of the lead screw 541. During use, it is convenient to drive the lead screw 541 to rotate through the output end of the drive motor 55. Subsequently, the position of the moving end 543 can be adjusted by the controller.
[0036] From the appendix Figure 4 As shown, the top two sides of the extrusion block 544 are provided with inclined portions. During use, the installation of the inclined portions allows the extrusion block 544 to be pressed and adhered to the side of the limiting block 512, and the limiting block 512 slides along the surface of the inclined portion, allowing the limiting block 512 to move automatically upward.
[0037] From the appendix Figure 5 As shown, the mounting bracket 4 includes an outer shell 41, side connecting plates 42, and reinforcing screws 43. The outer shell 41 is installed inside the body 1 of the expansion machine, and the side connecting plates 42 are symmetrically installed on both sides of the outer shell 41. The side connecting plates 42 and the body 1 of the expansion machine share the same threaded reinforcing screws 43. During use, the installation of the reinforcing screws 43 quickly locks the position of the side connecting plates 42, installing the outer shell 41 inside the body 1 of the expansion machine. This also facilitates the quick extraction and installation of the mounting bracket 4 and the positioning mechanism 5, and allows for adjustment of the corresponding positioning mechanism 5 for processing different specifications of pipes.
[0038] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
