Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe manufacturing technology, and in particular to a corrugated pipe manufacturing device with a telescopic structure. Background Technology

[0002] The production process of corrugated pipes (metal compensators) usually involves placing a stainless steel pipe into a specific mold, sealing both ends, and then filling the pipe with high-pressure gas or liquid. Under high pressure, the stainless steel pipe is squeezed to form the desired corrugated shape.

[0003] In traditional corrugated pipe manufacturing equipment, the position of the extrusion head is often fixed. When it is necessary to produce corrugated pipes of different lengths, the position of the extrusion head in traditional equipment cannot be flexibly adjusted. As a result, companies often need to replace different equipment or make complex modifications to existing equipment. This not only increases production costs, including equipment purchase costs and modification expenses, but also consumes a lot of time and manpower, resulting in low production efficiency. Moreover, frequent equipment replacement or modification may also affect the precision and stability of the equipment, thereby affecting the product quality of the corrugated pipes.

[0004] Therefore, developing a bellows manufacturing device with a telescopic structure to meet the above-mentioned production requirements is of great practical significance. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Reference Figure 1 This utility model provides a corrugated pipe manufacturing device with a telescopic structure, including a base 1, a lifting platform 2 on the base 1, an extrusion mechanism 3 installed on the lifting platform 2, two mirror-image mold closing mechanisms on the base 1 below the extrusion mechanism 3, and a sealing seat 4 on the base 1 between the two mold closing mechanisms.

[0020] The mold closing mechanism includes a mold closing bracket 6 with mold closing slide rails 8 on both sides. A mold closing cylinder 7 is mounted on the mold closing bracket 6. A mold base 9 is slidably mounted on the mold closing slide rails 8. The mold 10 is fixedly connected to the mold base 9 at both ends and fixedly connected to the piston rod of the mold closing cylinder 7 on its side. The mold closing bracket 6 has strip-shaped connecting holes 601 on both sides. Bolts pass through the strip-shaped connecting holes 601 to fix the mold closing bracket 6 to the base 1. The position of the mold closing mechanism can be finely adjusted by adjusting the position of the bolts in the strip-shaped connecting holes 601.

[0021] Reference Figure 2 , Figure 3In the extrusion mechanism 3, the support plate 301 and the lifting slide rail 302 are fixed to the side of the lifting platform 2. The support plate 301 is equipped with an extrusion cylinder 303. The lifting slide rail 302 is below the support plate 301 and is equipped with a support 307. The support 307 is equipped with a sealing air-filled seat 304. Both the support 307 and the sealed air-filled seat 304 have telescopic grooves 308 and inclined grooves 311 on their adjacent surfaces. The two telescopic grooves 308 are combined to form a complete channel. Two positioning sliders 5 are installed inside the telescopic grooves 308. The side wall of the telescopic grooves 308 has several positioning holes 309 that are adapted to the positioning sliders 5. The side of the sealed air-filled seat 304 has a screw 305. Rotating the screw 305 can drive the two positioning sliders 5 to move closer or further apart. The lower end of the piston rod of the extrusion cylinder 303 has a connecting support plate 310. A connecting rod 306 is provided between the positioning sliders 5 and the connecting support plate 310. One end of the connecting rod 306 is hinged to the connecting support plate 310, and the other end passes through the inclined groove 311 and is hinged to the positioning sliders 5. When the positioning sliders 5 are engaged in different positioning holes 309, the distance between the piston rod of the extrusion cylinder 303 and the sealed air-filled seat 304 can be adjusted to adapt to the production of corrugated pipes of different lengths.

[0022] Reference Figure 4 , Figure 5 In the positioning slider 5, a hinge seat 540 is provided at the top of the outer shell 501, and a telescopic cavity 502 is provided inside the outer shell 501. A threaded sleeve 505 adapted to the screw 305 is slidably installed in the telescopic cavity 502. A guide groove 503 is provided on the inner wall of the telescopic cavity 502, and a wedge block 506 and two guide blocks 507 are provided on the outer wall of the threaded sleeve 505. The wedge block 506 is located in the middle of the threaded sleeve 505, and the two guide blocks 507 are symmetrically arranged on both sides of it. A return spring 508 is provided between the guide block 507 and the end wall of the telescopic cavity 502. A positioning cavity 510 is set in the middle of the outer shell 501. A positioning pin 509 is provided in the positioning cavity 510, which penetrates the outer shell 501. The positioning pin 509 matches the positioning hole 309. When the wedge block 506 is aligned with the positioning pin 509, its end is pushed out of the outer shell 501. A compression spring 511 is provided between the positioning pin 509 and the bottom of the positioning cavity 510. When the two are misaligned, the compression spring 511 pushes the end of the positioning pin 509 back into the outer shell 501.

[0023] To facilitate understanding of this utility model, the following is combined with... Figure 1 - Figure 5 The working principle of this solution will be explained in detail:

[0024] During operation, the lower end of the stainless steel pipe is inserted into the sealing seat 4. Then, the mold closing cylinder 7 pushes the two molds 10 to close. The extrusion cylinder 303 drives the sealing inflation seat 304 to descend, sealing the upper and lower ends of the stainless steel pipe and filling it with high-pressure gas, thus extruding and forming a corrugated pipe.

[0025] When the distance between the sealing air seat 304 and the piston rod of the extrusion cylinder 303 needs to be adjusted according to the length requirements of the bellows, first rotate the screw 305 in one direction. At this time, the positioning pin 509 is fixed in the inner shell 501 of the positioning hole 309. The screw sleeve 505 moves towards one end of the telescopic cavity 502 with the rotation of the screw 305, so that the wedge block 506 is misaligned with the positioning pin 509. Under the action of the compression spring 511, the positioning pin 509 is dislodged from the positioning hole 309. At this time, the positioning slider 5 moves under the drive of the screw 305, thereby realizing the adjustment of the distance.

[0026] After adjusting to the appropriate spacing, the screw 305 needs to be rotated a certain arc to make the positioning hole 309 to be inserted intersect with the positioning pin 509. Then, the screw 305 is rotated in the opposite direction. At this time, the inclined surface of the wedge 506 abuts against the end of the positioning pin 509 inside the housing 501. In this way, when the positioning pin 509 is aligned with the positioning hole 309, the wedge 506 pushes the positioning pin 509 into it, thereby re-fixing the positioning slider 5. In practical applications, a scale and pointer can be set on the rotating side of the screw to determine the position of the positioning slider 5 in the telescopic groove 308 for easy operation by the operator.

[0027] After adjusting the spacing, the hinged relationship between the positioning slider 5 and the connecting rod 306, and the hinged relationship between the connecting rod 306 and the connecting support plate 310, ensures a stable connection between the sealing inflation seat 304 and the piston rod of the extrusion cylinder 303. During the corrugated pipe production process, the lifting platform 2, the mold closing mechanism, and the extrusion mechanism 3 cooperate with each other. Through precise mechanical structure and stable pneumatic control, the stability and reliability of the entire device are ensured, thereby producing high-quality corrugated pipes.

[0028] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
