Description

TECHNICAL FIELD

[0001] The application relates to a rubber hose and a rubber hose crimping field, in particular to a processing equipment of a high-pressure-resistant pipe assembly. BACKGROUND

[0002] The rubber hose for cleaning the airport runway usually adopts a high-pressure rubber hose, but at present, there are few rubber hoses suitable for cleaning the airport runway on the market, and the rubber hoses generally cannot meet the pressure of 1200 kg. In the case that the strength of the rubber hose meets the requirements, the existing rubber hose and joint will be pulled out when the pressure reaches 1200 kg. The high-pressure-resistant pipe assembly of the application can withstand a pressure of 2400 kg at most, so that the demand for cleaning the airport runway can be effectively met. In addition, in the case of crimping a long sleeve pipe, the conventional method needs manual control. Specifically, after the front half of the sleeve is extruded, the existing method needs to manually press the release button of the crimping machine, then adjust the position, press the crimping button of the crimping machine, then press the release button of the crimping machine again, then adjust the position again, and finally press the crimping button of the crimping machine again. Therefore, it can be seen that in the case of a long sleeve pipe, the existing method needs manual operation of the crimping machine multiple times and real-time adjustment of the position of the sleeve. In the case of a large-size high-pressure rubber hose, the high-pressure rubber hose itself is heavy, so two people are usually used for operation. Therefore, the existing method is troublesome and has low processing efficiency. In addition, two people operate one machine, which greatly increases the labor cost, and thus the profit of producing a large-size high-pressure rubber hose is low.

[0003] Therefore, there is a demand for a processing equipment of a high-pressure-resistant pipe assembly which is convenient for crimping a long sleeve pipe, has good adaptability, and has high strength at the connection between the rubber hose and the joint. SUMMARY

[0032] Processing equipment of schematic high-pressure resistant pipeline assembly

[0033] Reference Figures 1 to 3 According to a preferred embodiment of the present application, the high-pressure resistant pipeline assembly is used for cleaning an aircraft runway. As understood by those skilled in the art, a high-pressure hose is usually used for cleaning an aircraft runway. However, there are few high-pressure hoses suitable for cleaning an aircraft runway on the market, and most of them cannot meet the pressure of 2400 kg. Specifically, when the strength of the hose meets the requirements, the existing hose and joint will be pulled out when the pressure reaches 1200 kg. However, the high-pressure resistant pipeline assembly of the present application can be pulled out when the pressure reaches 2400 kg, which can effectively meet the demand of cleaning an aircraft runway.

[0034] The high-pressure resistant pipe assembly is described in detail below. The high-pressure resistant pipe assembly comprises a joint 10, a sleeve 20 and an insert 30. The sleeve 20 has an opening 201 and a first cavity 202. The opening 201 is in communication with the first cavity 202. The opening 201 and the first cavity 202 are also in communication with the outside. In addition, the insert 30 has an insertion end 31, an abutting end 32 and a connecting end 33. The abutting end 32 is connected to the insertion end 31 and the connecting end 33 respectively. The insertion end 31 passes through the opening 201 and is placed in the first cavity 202. The abutting end 32 is in contact with the wall of the sleeve 20 where the opening 201 is located. The joint 10 is threadedly connected to the connecting end 33.

[0035] It should be noted that the wall forming the first cavity 202 has a ring-shaped blocking part 2021. One end of the high-pressure rubber tube is placed in the first cavity 202 and is abutted against the ring-shaped blocking part 2021. The insertion end 31 is placed in the high-pressure rubber tube.

[0036] In addition, the wall forming the first cavity 202 has a ring-shaped limiting groove 203. The insertion end 31 also has a ring-shaped protrusion 311. When the abutting end 32 is in contact with the sleeve 20, the ring-shaped limiting groove 203 is opposite to the ring-shaped protrusion 311. It should be understood by those skilled in the art that the ring-shaped protrusion 311 can cooperate with the ring-shaped limiting groove 203 to prevent the insert 30 from being separated from the sleeve 20. Specifically, when the pressure is too large, the ring-shaped protrusion 311 and the ring-shaped limiting groove 203 rigidly contact to clamp the insert 30 and the sleeve 20, thereby improving the pull-out resistance of the insert 30.

[0037] In addition, the wall surface forming the first cavity 202 has a plurality of first annular extrusion blocks 2022 which are uniformly distributed and spaced apart, and the first annular extrusion blocks 2022 are located on the side of the annular limiting groove 203 away from the opening 201. In addition, the sleeve 20 of the present application is buckled by the processing equipment of the present application, that is, when the insert 30, the external high-pressure rubber tube and the sleeve 20 are matched together, the processing equipment applies force to the outer wall of the sleeve 20, so that the sleeve 20 is pressed to deform, that is, the wall surface forming the first cavity 202 and the wall surface forming the opening 201 move towards the center of the insert 30, that is, the size of the opening 201 and the first cavity 202 starts to decrease, so that the wall surface forming the opening 201 is placed between the abutting end 32 and the annular protrusion 311, and the annular protrusion 311 is directly in contact with the wall surface forming the first cavity 202, that is, the insert 30 is prevented from being separated from the sleeve 20 by the double limiting, and the plurality of first annular extrusion blocks 2022 extrude the external high-pressure rubber tube placed in the first cavity 202. It should be understood by those skilled in the art that the outer rubber of the external rubber tube placed in the first cavity 202 can be peeled off by an external peeling agent for a certain length, and those skilled in the art should understand that the high-pressure rubber tube includes an outer rubber layer, a steel wire layer 100 and an inner rubber layer 200, that is, the plurality of first annular extrusion blocks 2022 extrude the steel wire layer 100 of the high-pressure rubber tube, so that the steel wire layer 100 deforms, and because the plurality of first annular extrusion blocks 2022 are spaced apart, the deformed part of the steel wire layer 100 is placed between two adjacent first annular extrusion blocks 2022, so that the steel wire layer 100 extruded by the plurality of first annular extrusion blocks 2022 has a wavy shape.

[0038] In addition, the wall surface forming the first cavity 202 also has a second annular extrusion block 2023 located between the annular blocking part 2021 and the plurality of first annular extrusion blocks 2022, the annular blocking part 2021 is thin-walled, and the protruding size of the annular blocking part 2021 is greater than the protruding size of the second annular extrusion block 2023, so that when the processing equipment extrudes the sleeve 20, the annular blocking part 2021 will deform first, that is, the annular blocking part 2021 is crushed and deformed to both sides, first, the left side deformation of the annular blocking part 2021 will extrude the wall surface of the annular protrusion 311, so that the annular protrusion 311 is firmly placed in the annular limiting groove 203, and in addition, the right side deformation of the annular blocking part 2021 will extrude the steel wire layer 100 of the end of the high-pressure rubber tube placed in the first cavity 202, so that the end of the high-pressure rubber tube is placed between the annular blocking part 2021 and the second annular extrusion block 2023.

[0039] The protruding dimensions of the first annular extrusion block 2022 are the same as those of the second annular extrusion block 2023.

[0040] It should also be noted that the dimension of the first cavity 202 away from the opening 201 is its maximum dimension, that is, the end of the first cavity 202 away from the opening 201 is flared. Therefore, when the processing equipment presses the outer wall of the sleeve 20, the deformation of the end of the first cavity 202 away from the opening 201 will bend inward, thus causing the end of the first cavity 202 away from the opening 201 to narrow. In addition, the wall surface forming the first cavity 202 also has a third annular extrusion block 2024, and the third annular extrusion block 2024 is inclined at a predetermined angle, that is, extending towards the plurality of second annular extrusion blocks 2023. Extending a predetermined distance, and with the protruding dimension of the third annular extrusion block 2024 being smaller than that of the second annular extrusion block 2023, the processing equipment is configured to first extrude the front half of the sleeve 20, then extrude the rear half of the sleeve 20, and finally extrude the end of the sleeve 20 away from the opening 201, thereby causing the first cavity 202 to narrow. Since the third annular extrusion block 2024 is close to the end of the first cavity 202 away from the opening 201, the third extrusion block applies an inclined extrusion force to the wire layer 100, that is, after extrusion, the third extrusion block is in the shape of a barb, thereby improving the pull-out resistance of the rubber tube.

[0041] It should also be noted that the inner rubber portion of the hose of the present invention is different from the existing processing method. The existing method only peels off the outer rubber of the high-pressure hose, while the present invention peels off the inner rubber of the high-pressure hose. The high-pressure hose placed in the first cavity 202 has a predetermined length of inner rubber peeled off. However, it should be noted that, unlike peeling off the outer rubber, the inner rubber is not completely peeled off. In order to ensure sealing and also take into account pull-out resistance, the thickness of the inner rubber is 1-1.5mm, preferably 1.3mm.

[0042] The processing equipment of the present invention will be described in detail below to facilitate understanding of the advantages of the processing equipment of the present invention in processing the above-mentioned high-pressure resistant pipeline assembly.

[0043] Specifically, the processing equipment includes a body 40, which is placed on the bottom surface and has a second cavity with both ends connected.

[0044] The processing equipment includes a first extrusion assembly 50, which includes a first extrusion sleeve and a second extrusion sleeve. One end of the first extrusion sleeve is welded to the second extrusion sleeve to form a whole. It is worth mentioning that the first extrusion assembly 50 is movably disposed in the second cavity.

[0045] Further, the processing device comprises a third extrusion sleeve 60, which is also movably arranged in the second cavity, and the first extrusion assembly 50 and the third extrusion sleeve 60 are oppositely arranged and spaced apart by a predetermined distance, and the ends of the first extrusion assembly 50 and the third extrusion sleeve 60 away from each other are both arranged outside.

[0046] In addition, the processing device comprises a pressure receiving assembly 70, which is arranged in the second cavity, and the two sides of the pressure receiving assembly 70 are respectively in contact with the sides of the first extrusion assembly 50 and the third extrusion sleeve 60 away from each other. It is worth mentioning that the first extrusion assembly 50 and the extrusion sleeve are arranged to be movable in the direction of approaching each other by a predetermined distance, so as to extrude the pressure receiving assembly 70, and it is also worth mentioning that the pressure receiving assembly 70 is arranged to be deformed under pressure. Specifically, the pressure receiving assembly 70 comprises a plurality of pressure receiving blocks 71, which are arranged in a ring shape, and the plurality of pressure receiving blocks 71 are connected by springs. In addition, each of the pressure receiving blocks 71 has a pressure receiving surface 711 on both sides, and the sides of the first extrusion assembly 50 and the third extrusion sleeve 60 away from each other both have an extrusion surface 300, and the two extrusion surfaces 300 are respectively in contact with the two pressure receiving surfaces 711, so that when the first extrusion assembly 50 and the extrusion sleeve extrude the pressure receiving assembly 70, the plurality of pressure receiving blocks 71 contract inwardly by a predetermined distance, until a through hole is formed.

[0047] Among them, the sleeve 20 is arranged in the through hole and deformed under the extrusion of the plurality of pressure receiving blocks 71. Specifically, the abutting end 32 of the insert 30 is in contact with the side of the pressure receiving assembly 70 away from the first extrusion assembly 50, so as to ensure that the end of the sleeve 20 provided with the opening 201 can be extruded by the plurality of pressure receiving blocks 71.

[0048] Wherein the person skilled in the art should understand that when the length of the pressure receiving assembly 70 is less than the length of the sleeve 20, the existing conventional method is to manually adjust the position of the sleeve 20 to ensure that the existing pressing device can compact the sleeve, and the processing equipment of the application does not need manual adjustment, that is, the first extrusion assembly 50 and the third extrusion sleeve 60 are arranged to be able to move independently, and in order to ensure that the distance between the first extrusion assembly 50 and the third extrusion sleeve 60 is consistent during the positioning process, a plurality of connecting rods 400 are arranged between the first extrusion assembly 50 and the third extrusion sleeve 60, one end of each of the plurality of connecting rods 400 is slidably connected to the end of the first extrusion assembly 50 close to the third extrusion sleeve 60, and the other end of each of the plurality of connecting rods 400 is movably connected to the end of the third extrusion sleeve 60, and the ends of the plurality of connecting rods 400 are arranged to be unable to be separated from the first extrusion assembly 50 or the third extrusion sleeve 60.

[0049] Specifically, when the first extrusion assembly 50 moves away from the third extrusion sleeve 60, the third extrusion sleeve 60 is pulled by the plurality of connecting rods 400 and moves synchronously with the first extrusion assembly 50, and vice versa. That is, the first extrusion assembly 50, the pressure receiving assembly 70 and the third extrusion sleeve 60 of the application can first extrude the front half of the sleeve 20, then extrude the rear half of the sleeve 20, and finally extrude the end of the sleeve 20 away from the opening 201, which are three steps, and the conventional method needs manual control. Specifically, after the front half of the sleeve 20 is extruded, the existing pressing machine needs to be manually pressed, and then the position is adjusted, the pressing button of the pressing machine is pressed, and then the release button of the pressing machine is pressed, and then the position is adjusted, and finally the pressing button of the pressing machine is pressed. Therefore, it can be seen that the existing pressing machine needs to be operated multiple times by manual operation, and the position of the sleeve 20 needs to be adjusted in real time. In the case of large size high pressure rubber tube, the weight of the high pressure rubber tube itself is relatively heavy, so two people are usually used for operation. In summary, the existing processing method is relatively troublesome and has low processing efficiency, and two people operate one machine, which greatly increases the labor cost, thereby reducing the profit of producing large size high pressure rubber tube. The application does not need to be operated by two people, and it is relatively convenient when operated by one person, which solves the problem that manual operation needs to be operated multiple times to process the product, greatly improves the processing efficiency of the existing long sleeve 20, and effectively improves the profit of processing high pressure rubber tube.

[0050] It needs to be explained that the processing device further comprises a supporting assembly 80, the supporting assembly 80 further comprises a fixed tube 81, a second telescopic rod 82 and a second supporting plate 83, the fixed tube 81 is fixed at the bottom of the third extrusion sleeve 60, and the second telescopic rod 82 is telescopically arranged on the fixed tube 81, and the second supporting plate 83 is fixedly connected with one end of the second telescopic rod 82 away from the fixed tube 81.

[0051] It is worth mentioning that the second supporting plate 83 is arc-shaped, and the supporting assembly 80 can move synchronously when the third extrusion sleeve 60 moves. It is worth mentioning that the supporting assembly 80 is arranged to adapt to high-pressure rubber pipes of different sizes, so that workers can insert high-pressure rubber pipe assemblies of different specifications into the pressure receiving assembly 70. In addition, since the high-pressure rubber pipe can be placed on the first supporting plate, when the third extrusion sleeve 60 moves, workers only need to prevent the high-pressure rubber pipe from moving synchronously.

[0052] In addition, it needs to be explained that the extrusion mode of the present application is quite different from that of the existing buckle pressing machine. The extrusion length of the existing buckle pressing machine is determined by the size of its pressing block, and single extrusion is usually adopted. If a long sleeve 20 is encountered, manual adjustment is required for re-extrusion. The present application can expand the extrusion range of the pressure receiving assembly 70 and complete the sleeve buckling through single-area multiple extrusion. Compared with the existing single extrusion, the multiple extrusion mode can better ensure the buckling degree of the sleeve 20. When the sleeve 20 is slightly longer than the pressure receiving assembly 70, the multiple extrusion mode can expand the extrusion range of the pressure receiving assembly 70, so that manual adjustment can be performed, which greatly improves the problem of processing requiring secondary adjustment when the sleeve 20 is slightly longer than the pressure receiving assembly 70. Specifically, only the first extrusion assembly 50 can be moved, so that the pressure receiving assembly 70 moves towards the third extrusion sleeve 60 and synchronously shrinks. Conversely, the pressure receiving assembly 70 moves away from the third extrusion sleeve 60 and synchronously shrinks. That is, press left, press right, and then press in the middle, so as to process the sleeve 20 slightly longer than the pressure receiving assembly 70 through three extrusions.

[0053] It is worth mentioning that the outer wall of the first extrusion assembly 50 has a first annular sealing end 51 and a second annular sealing end 52, which are oppositely arranged and spaced apart by a predetermined distance, wherein the wall surface forming the second cavity has a first annular groove 401 and a second annular groove 402, which are oppositely arranged and spaced apart by a predetermined distance, wherein the first annular sealing end 51 is arranged in the first annular groove 401 and in contact with the bottom wall forming the first annular groove 401, and the second annular sealing end 52 is arranged in the second annular sealing groove 402 and in contact with the bottom wall forming the second annular groove 402. In addition, one end of the third extrusion sleeve 60 arranged in the second cavity also has a third annular sealing end 61, which is in contact with the bottom wall forming the second annular groove 402, and the third annular sealing end 61 and the second annular sealing end 52 are spaced apart by a predetermined distance, wherein the two ends of the plurality of connecting rods 400 are respectively connected to the side of the second annular sealing end 52 and the third annular sealing end 61 close to each other.

[0054] In addition, it is necessary to mention that the two side walls forming the first annular groove 401 and the two side walls forming the second annular groove 402 have an oil hole 403, and an oil tank 90 is also arranged in the machine body 40, and four oil pipes are connected to the four oil holes 403, that is, the first extrusion assembly 50 and the third extrusion sleeve 60 are moved by the oil path.

[0055] In addition, it is necessary to mention that since only one person is needed to operate, the end of the first extrusion assembly 50 away from the third extrusion sleeve 60 can be connected to an external power component, that is, the first extrusion assembly 50 is pushed and pulled by the external power component, so that the first extrusion assembly 50 and the third extrusion sleeve 60 are moved.

[0056] In summary, the processing equipment for the high-pressure-resistant pipeline assembly based on the embodiments of the present application is illustrated, which provides the advantages of convenient buckling of the long sleeve, good adaptability, high strength of the connection between the rubber pipe and the connector, etc.

[0057] It is worth mentioning that in the embodiments of the present application, the processing equipment for the high-pressure-resistant pipeline assembly has a simple structure and does not involve complex manufacturing processes and expensive materials, which has high economic efficiency. At the same time, for the manufacturers, the processing equipment for the high-pressure-resistant pipeline assembly provided by the present application is easy to produce and has low cost, which is more conducive to controlling the production cost and further conducive to product promotion and use.

[0058] Those skilled in the art will understand that the above description and the accompanying drawings are only examples of the embodiments of the present application and do not limit the present application. The purpose of the present application has been fully and effectively achieved. The functional and structural principles of the present application have been demonstrated and described in the embodiments, and the embodiments of the present application can be modified or changed in any way without departing from the principles.
