Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe forming apparatus, and in particular to a detachable corrugated pipe forming apparatus. Background Technology

[0002] Corrugated pipes mainly include metal corrugated pipes, corrugated expansion joints, corrugated heat exchange tubes, diaphragm boxes, and metal flexible hoses. Metal corrugated pipes are primarily used to compensate for pipeline thermal deformation, dampen vibrations, and absorb pipeline settlement deformation, and are widely used in industries such as petrochemicals, instrumentation, aerospace, chemicals, power, water conservancy, and metallurgy. Corrugated pipes made of plastics and other materials play an irreplaceable role in media transportation, power wiring, machine tools, and home appliances.

[0003] In the prior art, Chinese utility model patent with publication number "CN217018160U" and patent name "An Automobile Corrugated Pipe Forming Device" discloses a corrugated pipe forming device. The patent describes a technical solution that "achieves the effect of eliminating the disassembly and assembly steps of the sealing ring by the mutual cooperation between the main body, worktable, lower mold, upper mold, first hydraulic cylinder, second hydraulic cylinder, water inlet pipe, water stop pipe, pipe blank, telescopic groove, single tooth plate, fixed shaft, transmission gear, sealing pipe, clamping ring, sealing ring, limiting pipe, positioning flange and second spring, thus solving the problem that frequent disassembly and assembly of the sealing ring not only increases labor intensity but also affects the sealing performance of the sealing ring".

[0004] However, in actual use, the corrugated pipe forming device is difficult to disassemble and repair when the lower and upper molds are fixedly installed inside the device. At the same time, it is not convenient to quickly disassemble and replace the corresponding lower and upper molds according to the specifications of the corrugated pipe. This not only brings inconvenience to the disassembly and use of the lower and upper molds in the corrugated pipe forming device, but also reduces work efficiency and practicality.

[0005] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a detachable corrugated pipe forming device. Utility Model Content

[0006] The main objective of this invention is to provide a detachable corrugated pipe forming device, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A detachable corrugated pipe forming device includes a frame. A support frame is fixedly connected to the top surface of the frame, and first hydraulic cylinders are fixedly connected to the left and right sides of the support frame, respectively. An extrusion head is fixedly connected to the output end of each of the first hydraulic cylinders. A lower die base is also fixedly connected to the top surface of the frame, and symmetrical guide posts are fixedly connected to the top two sides of the lower die base. A second hydraulic cylinder is fixedly connected to the top surface of the support frame, and an upper die base is fixedly connected to the output end of the second hydraulic cylinder. The upper die base is movably connected to the guide posts through guide holes on its top surface. The top surface of the lower die base and the bottom surface of the upper die base are fixed by fixing mechanisms. The system is connected to a lower mold and an upper mold, with mold cavities respectively formed on the opposite walls of the lower and upper molds. The fixing mechanism includes an L-shaped rotating plate, a screw, a movable block, a connecting block, and a limiting block. The front and rear ends of the lower mold base and the upper mold base are respectively movably connected to the L-shaped rotating plate via rotating shafts. The screw is movably connected to the bottom surface of the vertical part of the L-shaped rotating plate via a rotating rod at the top end. The movable block is movably connected to the rear wall of the vertical part of the L-shaped rotating plate via a slider at the front end. The connecting block is fixedly connected to the front end of the slider and movably connected to the screw via a screw hole on the top surface. The limiting block is fixedly connected to the bottom surface of the movable block.

[0009] Furthermore, a set of symmetrical notches are respectively opened on the front and rear walls of the lower mold and the upper mold, and a limiting groove is opened on the inner bottom surface of the notch. Positioning holes are respectively opened on the four opposite ends of the lower mold and the upper mold.

[0010] Furthermore, positioning rods corresponding to positioning holes are fixedly installed on the opposite walls of the lower mold base and the upper mold base, and a set of left-right symmetrical rotating shafts are fixedly installed on the front and rear walls of the lower mold base and the upper mold base, respectively. A stop block is fixedly installed at the front end of the rotating shaft, and a first rotating hole is opened at the bottom of the front wall of the vertical part of the L-shaped rotating plate and is movably installed with the rotating shaft through the first rotating hole.

[0011] Furthermore, a sliding opening is provided on the front wall of the vertical part of the L-shaped rotating plate above the first rotating hole, and a second rotating hole is provided on the top surface of the horizontal part of the L-shaped rotating plate.

[0012] Furthermore, a rotating rod is fixedly installed at the top end of the screw, and the rotating rod is movably installed in the second rotating hole. A knob is fixedly installed at the top end of the rotating rod.

[0013] Furthermore, a slider is fixedly installed at the front end of the movable block, and the slider is movably installed in the sliding opening. A connecting block is fixedly installed at the front end of the slider, and a screw hole is opened on the top surface of the connecting block and threadedly connected to the screw rod through the screw hole. A limit block is also fixedly installed on the bottom surface of the movable block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, the lower mold and upper mold can be positioned and installed on the lower mold base and upper mold base respectively through the positioning holes and positioning rods. With the use of the fixing mechanism, the L-shaped rotating plate is rotated inward along the rotation axis through the first rotating hole until it can no longer be rotated. Then, the knob is turned, which drives the screw to rotate through the rotating rod. This causes the connecting block to move downward along the screw through the screw hole. The connecting block will drive the movable block to move synchronously in the notch through the slider until the limiting block is inserted into the limiting groove. This allows the lower mold and upper mold to be installed and fixed on the lower mold base and upper mold base respectively, thereby facilitating the disassembly and assembly of the lower mold and upper mold. This allows for timely disassembly and maintenance in case of failure of the lower mold and upper mold. At the same time, the lower mold and upper mold can be quickly disassembled and replaced according to the required specifications of the corrugated pipe to be produced, thereby improving work efficiency and the practicality of the device.

[0022] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a corrugated pipe forming device according to this utility model.

[0023] like Figure 1 - Figure 5As shown, a detachable corrugated pipe forming device includes a frame 1, a support frame 2 fixedly connected to the top surface of the frame 1, and a first hydraulic cylinder 3 fixedly connected to the left and right sides of the support frame 2 respectively. An extrusion head 4 is fixedly connected to the output end of the first hydraulic cylinder 3. A lower mold base 5 is also fixedly connected to the top surface of the frame 1, and symmetrical guide posts 7 are fixedly connected to the top sides of the lower mold base 5 respectively. A second hydraulic cylinder 9 is fixedly connected to the top surface of the support frame 2, and an upper mold base 10 is fixedly connected to the output end of the second hydraulic cylinder 9. The upper mold base 10 is movably connected to the guide posts 7 through a guide hole 12 on the top surface.

[0024] The specific operating principle of this corrugated pipe forming device is as follows:

[0025] The tube blank is placed into the cavity 8 on the top surface of the lower mold 6. The second hydraulic cylinder 9 is activated to drive the output end to push the upper mold base 10 downward. The upper mold base 10 moves upward through the guide hole 12 along the guide post 7 installed on the top surface of the lower mold base 5 until the upper mold 11 installed on the bottom surface of the upper mold base 10 and the lower mold 6 installed on the top surface of the lower mold base 5 are closed. Then, the first hydraulic cylinder 3 installed on both sides of the support frame 2 is activated. The first hydraulic cylinder 3 drives the output end to push the extrusion head 4 into the mold and extrudes the two ends of the tube blank in the mold. Under the constraint of the cavity 8 on the lower mold 6 and the upper mold 11, the tube blank will undergo plastic deformation, thereby forming a corrugated tube with a corrugated shape. After forming, the lower mold 6 and the upper mold 11 are opened again by the second hydraulic cylinder 9, and the formed corrugated tube can be taken out from the cavity 8.

[0026] The top surface of the lower mold base 5 and the bottom surface of the upper mold base 10 are fixedly connected to the lower mold 6 and the upper mold 11 respectively through the fixing mechanism 13. Mold cavities 8 are respectively opened on the opposite walls of the lower mold 6 and the upper mold 11. The fixing mechanism 13 includes an L-shaped rotating plate 20, a screw 24, a movable block 27, a connecting block 29 and a limiting block 31. The front and rear sides of the lower mold base 5 and the upper mold base 10 are movably connected to the L-shaped rotating plate 20 through the rotating shaft 18. The screw 24 is movably connected to the bottom surface of the vertical part of the L-shaped rotating plate 20 through the rotating rod 25 at the top end. The movable block 27 is movably connected to the rear wall of the vertical part of the L-shaped rotating plate 20 through the slider 28 at the front end. The connecting block 29 is fixedly connected to the front end of the slider 28 and is movably connected to the screw 24 through the screw hole 30 on the top surface. The limiting block 31 is fixedly connected to the bottom surface of the movable block 27.

[0027] like Figure 2 and Figure 3As shown, a set of symmetrical notches 14 are respectively opened on the front and rear walls of the lower mold 6 and the upper mold 11. The notches 14 can ensure that the movable block 27 can move in and out inside them. The bottom surface of the notch 14 is provided with a limiting groove 15. The limiting groove 15 is used to cooperate with the limiting block 31 to limit and fix the mold. The four opposite ends of the lower mold 6 and the upper mold 11 are respectively provided with positioning holes 16. The positioning holes 16 are used to cooperate with the positioning rod 17 to realize the positioning and installation of the mold.

[0028] like Figure 4 and Figure 5 As shown, positioning rods 17 corresponding to positioning holes 16 are fixedly installed on the opposite walls of the lower mold base 5 and the upper mold base 10 respectively. The positioning rods 17 are inserted into the positioning holes 16, so that the lower mold base 5 and the upper mold base 10 can be positioned and installed on the lower mold 6 and the upper mold 11 respectively. A set of left-right symmetrical rotating shafts 18 are fixedly installed on the front and rear walls of the lower mold base 5 and the upper mold base 10 respectively. A stop block 19 is fixedly installed at the front end of the rotating shaft 18. The bottom of the front wall of the vertical part of the L-shaped rotating plate 20 is provided with a first rotating hole 21 and is movably installed with the rotating shaft 18 through the first rotating hole 21. The L-shaped rotating plate 20 can be rotated left and right along the rotating shaft 18 through the first rotating hole 21 so that the movable block 27 can enter and exit in the notch 14. The stop block 19 installed at the front end of the rotating shaft 18 can prevent the L-shaped rotating plate 20 from moving off the rotating shaft 18.

[0029] like Figure 5 As shown, a sliding opening 22 is provided on the front wall of the vertical part of the L-shaped rotating plate 20 and above the first rotating hole 21. The sliding opening 22 is used to cooperate with the slider 28 to realize the sliding operation. A second rotating hole 23 is provided on the top surface of the horizontal part of the L-shaped rotating plate 20. The second rotating hole 23 is used to cooperate with the rotating rod 25 to realize the rotation operation.

[0030] like Figure 5 As shown, a rotating rod 25 is fixedly installed at the top of the screw 24, and the rotating rod 25 is movably installed in the second rotating hole 23. A knob 26 is fixedly installed at the top of the rotating rod 25. Rotating the knob 26 can drive the rotating rod 25 to rotate, so that the rotating rod 25 drives the screw 24 to rotate.

[0031] like Figure 5As shown, a slider 28 is fixedly installed at the front end of the movable block 27, and the slider 28 is movably installed in the slide 22. A connecting block 29 is fixedly installed at the front end of the slider 28, and a screw hole 30 is opened on the top surface of the connecting block 29 and threadedly connected to the screw rod 24 through the screw hole 30. A limit block 31 is also fixedly installed on the bottom surface of the movable block 27. Under the rotation of the screw rod 24, the connecting block 29 will move downward along the screw rod 24 through the screw hole 30, so that the connecting block 29 drives the slider 28 to slide in the slide 22. The slider 28 will drive the movable block 27 to move synchronously in the notch 14, so that the limit block 31 is inserted into the limit groove 15. The lower mold 6 and the upper mold 11 can be fixed on the lower mold base 5 and the upper mold base 10 respectively. This method also facilitates the subsequent disassembly of the lower mold 6 and the upper mold 11.

[0032] The specific operating principle of the fixing mechanism 13 in conjunction with the corrugated pipe forming device is as follows:

[0033] When the lower mold 6 and upper mold 11 malfunction, or when it is necessary to replace the lower mold 6 and upper mold 11 to produce corrugated pipes of different specifications, the knob 26 located on the top surface of the vertical part of the L-shaped rotating plate 20 is rotated in sequence. The knob 26 will drive the rotating rod 25 to rotate within the second rotating hole 23 opened on the top surface of the horizontal part of the L-shaped rotating plate 20. After the rotating rod 25 drives the screw 24 installed at the bottom to rotate, the connecting block 29 will move upward along the screw 24 through the screw hole 30 opened on the top surface. The connecting block 29 will drive the slider 28 to... The L-shaped rotating plate 20 slides within the sliding opening 22 on the front wall of its vertical section, causing the slider 28 to move the movable block 27 upward within the notch 14 until the limiting block 31 moves out of the limiting groove 15 on the bottom surface of the notch 14, preventing the knob 26 from rotating. Then, the L-shaped rotating plate 20 is flipped outwards, allowing it to rotate outwards along the rotating shaft 18 through the first rotating hole 21 on the lower part of the front wall until the movable block 27 moves out of the notch 14. This allows the lower mold 6 and the upper mold 1 to be installed. 1. Remove the lower mold base 5 and upper mold base 10 respectively. After maintenance or when installing the required lower mold 6 and upper mold 11, install the lower mold 6 and upper mold 11 onto the lower mold base 5 and upper mold base 10 respectively. After the positioning rods 17 installed on the lower mold base 5 and upper mold base 10 are inserted into the corresponding positioning holes 16, rotate the L-shaped rotating plate 20 inward until the movable block 27 enters the notch 14 and the L-shaped rotating plate 20 can no longer rotate, then rotate the knob 26 in the opposite direction to move the movable block 27. 7. Move downwards within the notch 14 until the limiting block 31 is inserted into the limiting groove 15 and the knob 26 cannot be rotated. Then, the lower mold 6 and the upper mold 11 can be installed and fixed on the lower mold base 5 and the upper mold base 10, thereby facilitating the disassembly and assembly of the lower mold 6 and the upper mold 11. This allows for timely disassembly and repair in case of malfunction of the lower mold 6 and the upper mold 11. At the same time, the lower mold 6 and the upper mold 11 can be quickly disassembled and replaced according to the required specifications of the corrugated pipe to be produced, thereby improving work efficiency and the practicality of the device.
