Description

TECHNICAL FIELD

[0001] The utility model relates to corrugated pipe processing technical field, concretely relates to a large -diameter corrugated pipe sealing ring forming device. BACKGROUND

[0002] In the field of industrial manufacturing, especially in the product development process involving pipeline systems, large-diameter corrugated pipes, as an important component, are widely used in various complex environments. Due to their unique physical properties, such as high flexibility, corrosion resistance, and good pressure-bearing capacity, large-diameter corrugated pipes have irreplaceable application value in many industries such as petroleum, chemical industry, shipbuilding, aerospace, etc.

[0003] During the actual installation process of large-diameter corrugated pipes, multiple large-diameter corrugated pipes need to be connected, so the sealing between large-diameter corrugated pipes is particularly important. The traditional sealing method mainly relies on adding independent sealing rings to the large-diameter corrugated pipes and using special fixing devices to maintain their position. Although this method can basically achieve sealing, it still has some problems:

[0004] The additional sealing ring and its fixing device increase the assembly complexity of the large-diameter corrugated pipe, prolong the production cycle, and also increase the manufacturing cost.

[0005] Secondly, the sealing ring fixed by the fixing device may deform or be damaged due to stress concentration during long-term use, greatly reducing the service life and affecting the overall sealing performance of the large-diameter corrugated pipe.

[0006] Therefore, there is an urgent need for a large-diameter corrugated pipe sealing ring forming device that can directly bond the sealing ring to the large-diameter corrugated pipe during the production stage, solving the problems of high assembly complexity, high manufacturing cost, and short service life caused by the need for a fixing device to fix the sealing ring in the prior art. SUMMARY

[0007] The technical problem solved by the utility model is to provide a large-diameter corrugated pipe sealing ring forming device that can directly bond the sealing ring to the large-diameter corrugated pipe during the production stage, solving the problems of high assembly complexity, high manufacturing cost, and short service life caused by the need for a fixing device to fix the sealing ring in the prior art.

[0008] The basic scheme provided by the utility model is a large-diameter corrugated pipe sealing ring forming device, which comprises an adjustable spacing corrugated pipe support roller frame and a sealing ring extrusion molding machine.

[0009] The adjustable spacing corrugated pipe support roller frame is used to support and rotate the large-diameter corrugated pipe.

[0010] The sealing ring extrusion molding machine includes a sealing ring extrusion mechanism for heating and extruding the sealing ring material and a bellows heating mechanism for preheating the large-diameter bellows;

[0011] A die head is fixedly provided on the discharge port of the sealing ring extrusion mechanism. The die head is provided with a discharge through hole along the direction of the discharge port. The die head is provided with a vertical guide groove connected with the discharge through hole.

[0012] The principle and advantage of the utility model are as follows: in this scheme, first, according to the diameter of the large-diameter corrugated pipe to be processed, the corrugated pipe support roller frame with adjustable spacing is adjusted to achieve horizontal support for the large-diameter corrugated pipe, and then the large-diameter corrugated pipe is rotated.

[0013] Afterwards, the position on the large-diameter corrugated tube where the sealing ring is to be set is heated by the bellows heating mechanism. As it rotates, the position heated by the bellows heating mechanism will rotate to the discharge port of the sealing ring extrusion mechanism. At this time, since a die head is set on the discharge port, the discharge through-hole of the die head is connected to the discharge port. At this time, the sealing ring extrusion mechanism will heat and extrude the sealing ring material, and it will be squeezed out through the discharge port and the discharge through-hole in turn and adhere to the position where the large-diameter corrugated tube has just been heated. Since the corresponding vertical guide groove is connected to the discharge through-hole, the sealing ring material adhered to the large-diameter corrugated tube will be restricted and limited by the vertical guide groove, that is, the amount of sealing ring material on the large-diameter corrugated tube is limited. At the same time, the vertical guide groove can also limit and extrude the excess sealing ring material to the left and right, so that the bubbles in the sealing ring material adhered to the large-diameter corrugated tube are squeezed out, thereby realizing the removal of bubbles in the sealing material. As the large-diameter corrugated pipe to be processed rotates, the sealing material with the same shape as the discharge hole will be squeezed by the vertical guide groove, so that the sealing material changes from the same shape as the discharge hole to the same shape as the vertical guide groove and eliminates bubbles in the sealing material.

[0014] 1. The vertical guide groove on the die head not only helps the sealing ring material to flow out evenly, but also plays a protective role during the extrusion process, preventing the sealing ring from being disturbed by the outside world, ensuring that the final sealing ring has a complete and beautiful shape.

[0015] 2. The bellows is locally heated in advance by the bellows heating mechanism, and then the sealing ring material is accurately extruded to the heated position by the sealing ring extrusion mechanism, ensuring good bonding between the sealing ring and the bellows and improving the sealing quality and durability.

[0016] 3. The entire process from the support and preheating of the bellows to the extrusion molding of the sealing ring is automatically completed by a special mechanism, which reduces the difficulty of operation and reduces errors caused by human factors.

[0017] 4. Through the coordination between the bellows support roller frame with adjustable spacing and the sealing ring extrusion molding machine, the sealing ring can be directly bonded to the large-diameter corrugated pipe during the production stage. Compared with the existing technology that requires a fixing device to fix the sealing ring, this solution can directly sleeve the large-diameter corrugated pipe during use after the sealing ring is bonded, which greatly improves the assembly efficiency and reduces the assembly complexity. At the same time, the entire production cost is also greatly reduced. Secondly, the entire sealing ring is integrated with the large-diameter corrugated pipe, which greatly ensures the uniformity of the force on the sealing ring and greatly improves the service life of the sealing ring.

[0023] The sliders can slide freely on the track and are connected together by a fixed plate to form an adjustable support unit. The rotating shafts between the support frames are equipped with rollers for directly contacting and supporting the corrugated pipe.

[0024] The fixing block at the bottom of the fixing plate is provided with a rotating hole matched with the external thread of the rotating rod. One end of the rotating rod extends into the fixing base, and the other end extends into the fixing block. The fixing block can move back and forth on the rotating rod by rotating the rotating rod, the position of the sliding block on the track can be changed, and the distance between the two groups of supporting roller frames can be adjusted to adapt to corrugated pipes of different diameters.

[0025] Only one of the four rollers on the two supporting roller frames is controlled to rotate by the first motor. Specifically, the first motor is installed at the lower part of the fixing plate of one of the rolling supporting mechanisms, and a first gear is installed on the motor shaft. The first gear is connected with a second gear on the rotating shaft through a chain.

[0026] 1. The distance between the two rollers on each supporting roller frame can be adjusted by rotating the rotating rod, which can adapt to corrugated pipes of different diameters and expand the application range of the device.

[0027] 2. The introduction of the first motor and the chain transmission mechanism allows the speed and direction of the rotating shaft to be accurately controlled by an electric method, thereby controlling the rotation speed of the corrugated pipe, which is beneficial to realize automatic production and improve efficiency.

[0028] 3. The threaded connection design of the rotating rod with the fixing block and the fixing base makes it simple and fast to adjust the distance between the supporting roller frames, and is also beneficial to daily maintenance and troubleshooting.

In this embodiment, the discharge pipe 12 corresponding to the discharge port is fixed with the die head 13 by screws.

[0052] Firstly, the size of the large-diameter corrugated pipe to be processed is determined, then the interval between the two rollers 7 on the first support roller frame is adjusted by rotating the rotating handle, so that the two rollers 7 on the first support roller frame can support the large-diameter corrugated pipe, then the rotating handle on the second support roller frame is rotated to adjust the interval between the corresponding two rollers 7, so that the two rollers 7 on the second support roller frame can support the large-diameter corrugated pipe.
