Description

Technical Field

[0001] This utility model relates to the field of steel wire mesh reinforced pipe processing technology, specifically a steel wire mesh reinforced pipe end face sealing and forming device. Background Technology

[0002] Steel wire mesh reinforced composite pipe is a new type of improved steel-reinforced plastic composite pipe, also known as SRTP pipe. This composite pipe overcomes the shortcomings of both steel pipe and plastic pipe while retaining their respective advantages. It is widely used in water supply, gas transmission and other fields. After its production, the pipe ends usually need to be sealed.

[0003] In the prior art, when the sealing extrusion process is carried out, the forming mold often makes contact with the end of the pipe, resulting in phenomena such as folding or insufficient sealing thickness. This is especially noticeable when processing pipes with a diameter of 200 mm. Some pipes, due to short heating time, may not fold, but there may still be insufficient sealing material on the end face, resulting in defects such as thin sealing.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a steel wire mesh reinforced pipe end face sealing and forming device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A steel wire mesh reinforced pipe end-face sealing and forming device includes a processing table. Support legs are fixedly connected to the four corners of the bottom of the processing table. A support column is fixedly connected to the rear of the surface of the processing table. A first cylinder is fixedly installed at the front of the top of the support column. A rectangular block is fixedly connected to the end of the first cylinder. A fixed pressure plate is movably connected to the bottom of the rectangular block. Placement plates are fixedly connected to the front of both sides of the processing table. A second cylinder is disposed on the surface of the placement plate. A forming mold is movably connected to the end of the second cylinder. Multiple sets of annular frame plates are fixedly connected to the front of the forming mold. The front arc opening of the annular frame plates is larger than the rear opening. Multiple sets of annular frame plates form multiple forming grooves, and the gaps between the multiple sets of forming grooves are designed to decrease in size.

[0008] Preferably, a threaded post is fixedly connected to the top center of the fixed pressure plate, and a threaded hole is opened at the bottom of the rectangular block. By inserting the threaded post into the threaded hole and then rotating it, people can quickly replace different fixed pressure plates according to the diameter of the pipe.

[0009] Preferably, a counterweight is fixedly connected to the bottom of the support leg. The bottom area of ​​the counterweight is larger than the top area. By setting a counterweight with a special shape, the contact area with the ground is increased, the stability of the processing table is increased, and the extrusion molding step can be performed more stably.

[0010] Preferably, a connecting block is fixedly connected to the end of the second cylinder, and a mating groove is formed on the surface of the connecting block. A mating block is fixedly connected to the center of the back of the molding mold, and a rubber anti-slip sleeve is fixedly connected to the inner wall of the mating groove. By inserting the molding mold into the mating groove through the provided mating block, the molding mold can be quickly connected and assembled with the second cylinder, making disassembly and assembly convenient and easy for people to replace.

[0011] Preferably, extension blocks are fixedly connected to both sides of the molding die, and the surface of the extension blocks is provided with anti-slip ridges. By providing extension blocks with anti-slip ridges, people can more easily grasp the molding die, thereby facilitating docking operations between it and the No. 2 cylinder.

[0012] Preferably, the inner wall of the docking groove and the surface of the docking block are provided with limit insertion holes. A fixing rod is inserted into the inside of the limit insertion hole. By inserting the fixing rod into the limit insertion hole, the mold can be fixed after installation, ensuring the stability of the mold and the No. 2 cylinder after docking and installation.

[0013] Preferably, a rectangular piece is fixedly connected to the top of the fixed plug rod, and a limiting block is fixedly connected to the bottom of the rectangular piece near its edge. A limiting slot is formed at the top of the connecting block near its edge. Magnetic pads are fixedly connected to the bottom of the limiting block and inside the limiting slot. Through the limiting block, after the fixed plug rod is fully inserted into the limiting hole, it will be inserted into the limiting slot. Subsequently, it is fixed by the attraction of two sets of magnetic pads, so that the fixed plug rod and the connecting block can be tightly connected, ensuring the stability of the fixed plug rod after installation.

[0014] Preferably, a protrusion is fixedly connected to the top center of the rectangular piece, and two sets of limiting pull holes are provided on the surface of the protrusion. By providing a protrusion with limiting pull holes, people can easily pull the fixed plug out from the limiting plug hole by hooking it with their fingers and pulling it upward.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. By reducing the size of the forming groove on the forming mold and increasing the arc at the inlet, the heated material can be effectively pushed back during forming. Because the groove width is smaller than the wall thickness of the tube, the material is not easily squeezed out during forming and extrusion, so there will be no edge flipping. This allows more material to be heated to effectively seal the front end and ensure the required seal thickness.

[0017] 2. By inserting the mating block on the back of the molding mold into the mating groove on the surface of the connecting block, the molding mold can be quickly connected and assembled with the No. 2 cylinder. This makes disassembly and assembly convenient and easy for people to replace. Then, the fixing rod is inserted into the limiting hole to fix the mold after installation, ensuring the stability of the molding mold and the No. 2 cylinder after installation. After the fixing rod is fully inserted into the limiting hole, the limiting block will be inserted into the limiting slot. Then, it is fixed by two sets of magnetic pads, so that the fixing rod and the connecting block can be tightly connected, ensuring the stability of the fixing rod after installation.

A fixed pressure plate 5 is movably connected to the bottom of the rectangular block 4. Placement plates 6 are fixedly connected to the front of both sides of the processing table 1. A second cylinder 7 is provided on the surface of the placement plate 6. A forming mold 8 is movably connected to the end of the second cylinder 7. Multiple sets of annular frame plates 9 are fixedly connected to the front of the forming mold 8. The front arc opening of the annular frame plate 9 is larger than the rear opening. Multiple sets of annular frame plates 9 form multiple forming grooves, and the gap between the multiple sets of forming grooves is designed to decrease in size.

[0029] In this embodiment, a threaded post is fixedly connected to the top center of the fixed pressure plate 5, and a threaded hole is opened at the bottom of the rectangular block 4. By inserting the threaded post into the threaded hole and then rotating it, people can quickly replace different fixed pressure plates 5 according to the diameter of the pipe.

[0030] In this embodiment, a counterweight is fixedly connected to the bottom of the support leg. The bottom area of ​​the counterweight is larger than the top area. By setting a counterweight with a special shape, the contact area with the ground is increased, the stability of the processing table 1 is increased, and the extrusion molding step can be performed more stably.

[0031] In this embodiment, a connecting block 12 is fixedly connected to the end of the second cylinder 7. A mating groove 13 is provided on the surface of the connecting block 12. A mating block 11 is fixedly connected to the center of the back of the molding mold 8. A rubber anti-slip sleeve is fixedly connected to the inner wall of the mating groove 13. By inserting the mating block 11 into the mating groove 13, the molding mold 8 can be quickly connected and assembled with the second cylinder 7. The assembly and disassembly are convenient and easy for people to replace.

[0032] In this embodiment, extension blocks 10 are fixedly connected to both sides of the molding mold 8. The surface of the extension blocks 10 is provided with anti-slip ridges. By providing extension blocks 10 with anti-slip ridges, people can more easily grasp the molding mold 8, thereby facilitating docking operations between it and the second cylinder 7.

[0033] In this embodiment, both the inner wall of the docking groove 13 and the surface of the docking block 11 are provided with limiting insertion holes 14. A fixing rod 15 is inserted into the inside of the limiting insertion hole 14. By inserting the fixing rod 15 into the limiting insertion hole 14, the mold 8 can be fixed after installation, ensuring the stability of the mold 8 after docking and installation with the second cylinder 7.

[0034] In this embodiment, a rectangular piece is fixedly connected to the top of the fixed insertion rod 15, and a limiting block 17 is fixedly connected to the bottom of the rectangular piece near the edge. A limiting slot 19 is opened at the top of the connecting block 12 near the edge. Magnetic pads 18 are fixedly connected to the bottom of the limiting block 17 and the inside of the limiting slot 19. After the fixed insertion rod 15 is fully inserted into the limiting insertion hole 14, it will be inserted into the limiting slot 19. Then, it will be fixed by the two sets of magnetic pads 18, so that the fixed insertion rod 15 and the connecting block 12 can be tightly connected, ensuring the stability of the fixed insertion rod 15 after insertion and installation.

[0035] In this embodiment, a protrusion 16 is fixedly connected to the top center of the rectangular piece. Two sets of limiting pull holes are provided on the surface of the protrusion 16. By setting the protrusion 16 with limiting pull holes, people can easily pull the fixed plug rod 15 out of the limiting plug hole 14 by hooking it with their fingers and pulling it upward.

[0036] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0037] In practical application, the forming mold 8 is lifted by grasping the extension block 10, and then inserted into the mating groove 13 on the surface of the connecting block 12 through the mating block 11 on its back. Subsequently, multiple sets of limiting insertion holes 14 overlap each other. At this time, the fixing rod 15 is inserted into the limiting insertion hole 14 to fix the installed forming mold 8, ensuring the stability of the forming mold 8 after docking with the second cylinder 7. After the fixing rod 15 is fully inserted into the limiting insertion hole 14, the limiting block 17 will be inserted into the limiting slot 19, and then fixed by two sets of magnetic pads 18, so that the fixing rod 15 and the connecting block 12 can be tightly connected, ensuring the stability of the fixing rod 15. After the above operations are completed, the pipe is placed on the processing table 1. The fixing plate 5 moves downward under the drive of cylinder 3 to press and fix the pipe. Then, the forming mold 8 clamps and extrudes the pipe from both ends under the push of cylinder 7. Because the forming groove of the forming mold 8 is small and the arc at the inlet is large, the heated material can be effectively pushed back during forming. Because the groove width is smaller than the wall thickness of the pipe, the material is not easily squeezed out during forming and extrusion, so there will be no edge flipping. This allows more material to be heated to effectively seal the front end and ensure the required seal thickness.

[0038] In summary, by utilizing the above-mentioned technical solution of this utility model, the forming groove on the forming mold 8 is reduced in size, and the arc at the inlet is increased, allowing the heated material to be effectively pushed back during forming. Because the groove width is smaller than the wall thickness of the tube, the material is less likely to be squeezed out during forming and extrusion, thus preventing edge flipping. This allows for heating more material to effectively seal the front end, ensuring the required seal thickness. The mating block 11 on the back of the forming mold 8 is inserted into the mating groove on the surface of the connecting block 12. Within 13, the molding mold 8 can be quickly connected and assembled with the second cylinder 7, making disassembly and assembly convenient and easy for people to replace. Then, the fixing rod 15 is inserted into the limiting socket 14 to fix the mold 8 after installation, ensuring the stability of the molding mold 8 after docking with the second cylinder 7. After the fixing rod 15 is fully inserted into the limiting socket 14, the limiting block 17 will be inserted into the limiting slot 19, and then fixed by two sets of magnetic pads 18, so that the fixing rod 15 and the connecting block 12 can be tightly connected, ensuring the stability of the fixing rod 15 after insertion and installation.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
