Description

Technical Field

[0001] The present invention relates to the technical field of metal hoses, and in particular to a metal hose netting installation device and a netting method thereof. Background Art

[0002] Metal hoses primarily utilize the effective expansion and contraction of their bellows to reduce vibration and vibration, making them ideal for pneumatic equipment such as compressors, which experience high pressure and vibration. The wire mesh sleeve within the metal hose enhances its strength and prevents mechanical damage. It protects the bellows from damage and ensures its ability to withstand axial and radial static loads, as well as the pulsating forces of liquids and other fluids flowing through the pipe. The meshing process involves combining the wire mesh sleeve with the bellows and ferrule components according to process requirements.

[0003] The mesh component in the metal hose is an important component of the metal hose, which directly affects the pressure bearing capacity and flexibility of the metal hose. In order to reliably put the mesh on the surface of the pipe body (i.e. the corrugated pipe body), the traditional meshing process requires the cooperation of multiple people to lift the pipe body from the ground to a certain height, and then put the mesh on the surface of the corrugated pipe body and tighten it manually. The pulling distance is also purely manual. Due to the weight of the corrugated pipe body itself and other reasons, the mesh is easy to shake when tightened and uneven force occurs on the upper and lower surfaces, which greatly affects the quality of the meshing. As a result, the same batch of products often have different mesh tightness and poor product identity. When some pipe fittings with heavier bodies are meshed, the friction between the steel wire and the corrugated pipe is large, which may cause wear of the thin-walled corrugated pipe body or obvious marks and other product defects, but the traditional meshing method cannot effectively avoid this. A small number of metal hose products have special meshing equipment made for them due to their large output. However, due to the differences in diameter, length, pressure, etc. of metal hose products, such meshing equipment can generally only be used for specific products and is not widely promoted. In actual application, the following problems exist in the use of traditional meshing technology:

[0004] 1. Due to factors such as uneven force during meshing, the mesh will often be unevenly tight, resulting in inconsistent coaxiality between the mesh and the two ends of the bellows, affecting the quality of the meshing process. In addition, the mesh waste material cut off at the end is generally large, resulting in material waste.

[0005] 2. After the mesh is put on the surface of the pipe, in order to ensure that the mesh is evenly covered and wrinkles are not formed, multiple people are required to manually push and iron the surface of the mesh repeatedly, which increases the labor intensity, low work efficiency and poor effect;

[0006] 3. In summary, the traditional mesh-wrapping process has low efficiency, the entire operation process is time-consuming and labor-intensive, and is not conducive to the mesh-wrapping assembly between the mesh sleeve and the corrugated pipe, which greatly increases labor costs and production costs. The mesh-wrapping quality is unreliable, resulting in poor product identity. Summary of the Invention

[0007] Therefore, the technical problem to be solved by the present invention is to overcome the low working efficiency of the metal hose meshing method in the existing technology, the time-consuming and labor-intensive operation process, which greatly increases labor costs and production costs, and the unreliable meshing quality, resulting in poor product identity.

[0018] The above-mentioned metal hose net installation equipment also includes a motor assembly that drives the pulley component to slide back and forth, and two net pulling hooks for hooking and pulling at both ends of the net. The net sleeve mounted on the corrugated tube body can be pre-tightened by the two net pulling hooks. The motor assembly is respectively connected to the pulley component and the net pulling hook through the motor tow hook.

[0019] In the above-mentioned metal hose net installation equipment, the pulley component includes a pulley frame provided with the central through hole, an inner cavity arranged in the pulley frame for installing and accommodating the net ring pressing assembly, and a traction steel rope arranged on the pulley frame and connected to the motor tow hook.

[0020] In the above-mentioned metal hose mesh installation equipment, the mesh ring pressing assembly includes two semicircular pressure rings relatively movably arranged in the inner cavity, and two tension adjustment rings rotatably arranged on the side edges of the pulley frame and respectively connected to the two semicircular pressure rings. The two semicircular pressure rings are relatively provided with two arc clamping grooves, and the two tension adjustment rings are used to adjust and drive the two semicircular pressure rings to approach each other or separate from each other in the middle through hole.

[0021] The present invention also provides a method for netting a metal hose, which comprises the following steps: using any of the above-mentioned netting installation devices for the metal hose, and netting a corrugated pipe body with the above-mentioned netting installation device:

[0022] Step 1: Sleeve the bellows onto the support rod, and position the bellows on the support rod by moving the rear end locking piece and the front end locking piece along the axial direction of the support rod and locking them at both ends of the bellows.

[0023] Step 2: Put the mesh sleeve on the surface of the corrugated pipe body, select a mesh ring pressing assembly of appropriate size and install it on the pulley component, push the pulley component to hug the mesh ring pressing assembly on the corrugated pipe body covered with the mesh sleeve, and adjust the mesh ring pressing assembly to fit tightly with the surface of the mesh sleeve;

[0024] Step 3: Drive the pulley component to move back and forth along the axial direction of the support rod, and drive the mesh ring pressing assembly to push back and forth on the surface of the mesh sleeve several times, so that the mesh sleeve is tightly pressed on the corrugated tube body.

[0025] Step 4: Put the clamping sleeve components on both ends of the corrugated tube body to clamp the mesh sleeve, so that the clamping sleeve component, the mesh sleeve and the corrugated tube body are tightly connected, and cut off the excess mesh sleeve at the clamping sleeve.

[0026] In the above-mentioned metal hose mesh wrapping method, in step one, the two ends of the corrugated tube body are respectively positioned against the first protruding structure of the rear end locking piece and the second protruding structure of the front end locking piece to keep the coaxiality of the two ends of the corrugated tube body consistent.

[0027] In the above-mentioned method of wrapping a metal hose with a mesh, in the step 2, two mesh hooks are used to hook the two ends of the mesh, and the mesh that is inserted into the corrugated tube body is pre-tightened. The two mesh hooks are driven by the motor assembly to achieve tightening; and the pulley component in the step 3 can be driven by the motor assembly to move back and forth along the axial direction of the support rod.

[0028] The technical solution of the present invention has the following advantages over the prior art:

[0029] 1. In the metal hose mesh installation device provided by the present invention, when putting on the mesh, the corrugated tube body is first put on the support rod, and the two ends of the corrugated tube body are locked by the rear end locking piece and the front end locking piece when moving relative to each other along the support rod, so as to position the corrugated tube body on the support rod. At this time, the mesh sleeve is passed through the surface of the corrugated tube body, and then the pulley component is used to drive the mesh ring pressing assembly to be put on the outside of the corrugated tube body, and the mesh ring pressing assembly is embraced and fitted on the mesh sleeve. Subsequently, the pulley component is driven to slide back and forth along the axial direction of the support rod, driving the mesh ring pressing assembly to push back and forth on the surface of the mesh sleeve, thereby straightening the wrinkled and uneven mesh sleeve and pressing it tightly on the corrugated tube body to improve the mesh sleeve process effect, and finally the mesh sleeve is clamped on both ends of the corrugated tube body with a clamping sleeve. The mesh installation equipment using this technical solution can be applied to the mesh processing of metal hoses of different specifications. The mesh has uniform tightness, ensuring the coaxiality of the mesh at both ends of the corrugated pipe body, and avoiding wrinkles, bumps and unevenness of the mesh on the pipe body, greatly improving the quality of the mesh process, ensuring the identity of the product, reducing waste generation, and optimizing the entire mesh process flow, which not only reduces labor, but also improves work efficiency, reduces manufacturing costs, and has good market benefits.

[0030] 2. In the metal hose mesh installation device provided by the present invention, the rear end locking piece and the front end locking piece are movably arranged on the support rod. By moving and adjusting the fastening distance L between the two, the mesh process requirements of metal hoses of different lengths can be met, and it is suitable for the lengths of most metal hoses. Moreover, the rear end locking piece and the front end locking piece of different adaptive diameters can also be replaced, so as to meet the mesh process requirements of metal hoses of different diameters. This design increases the scope of use of the mesh installation equipment, has good versatility, and can better meet the needs of different users.

[0031] 3. In the net-sleeving installation device of the metal hose provided by the present invention, the first protrusion structure and the second protrusion structure are respectively set at the same height on the rear end locking piece and the front end locking piece, and the size of the first protrusion structure and the second protrusion structure is roughly adapted to the size of the two end ports of the corrugated tube body, so that the two ends of the corrugated tube body are respectively sleeved on the first protrusion structure and the second protrusion structure, and the first protrusion structure and the second protrusion structure play a positioning and supporting role for the two ends of the corrugated tube body, and then the two ends of the corrugated tube body can be limited and locked by adjusting and moving the rear end locking piece and the front end locking piece. This structural setting forms an annular gap between the corrugated tube body and the support rod, which can avoid extrusion and friction between the corrugated tube body and the support rod during the net-sleeving and tightening process, play a protective role for the tube body, and the net-sleeving installation force is more uniform. This installation method can also effectively ensure the coaxiality of the two ends of the corrugated tube body.

[0032] 4. In the net-sleeving installation device of the metal hose provided by the present invention, the rear end locking piece is fixed to the support rod by passing the fastener through the fixing hole on the annular platform, and then the front end locking piece is screwed in from the front end of the support rod through the cooperation of the threaded sleeve and the threaded section, and gradually moves closer to the side of the rear end locking piece. This front end locking piece is arranged on the support rod by means of a threaded structure and has a thread self-locking effect, so that the rear end locking piece and the front end locking piece are pressed against the two ends of the corrugated tube body after relative movement of a certain distance, thereby playing a limit locking role for the corrugated tube body sleeved on the support rod, effectively avoiding the corrugated tube body from sliding with the net sleeve when the net sleeve is sleeved or tightened. This connection structure is simple in design, and is relatively convenient for installation and disassembly of the corrugated tube body on the support rod, with reliable cooperation and easy and labor-saving operation.

[0033] 5. In the metal hose mesh installation device provided by the present invention, after the mesh is put on the surface of the corrugated tube body, two mesh hooks are used to hook the two ends of the mesh, and under the drive of the motor assembly, the two mesh hooks relatively tighten the two ends of the mesh, thereby pre-tightening the mesh on the surface of the corrugated tube body, making it convenient for the subsequent pulley component to drive the mesh ring pressing assembly to perform a reciprocating pushing action on the surface of the mesh, thereby tightly pressing the mesh on the corrugated tube body. During this movement process, the pulley component can also be driven by the motor assembly to perform reciprocating movement, so that the force is applied more evenly and smoothly, reducing the intensity of manual labor, saving manpower, and improving work efficiency.

[0034] 6. In the metal hose mesh installation device provided by the present invention, the mesh ring pressing assembly consists of two semicircular pressing rings arranged to move relatively, and two tension adjustment rings are provided on both sides of the pulley frame to adjust and move the two semicircular pressing rings. This structural arrangement, by rotating and tightening the two tension adjustment rings, drives the two semicircular pressing rings to fit together in the middle through hole and tightly press on the surface of the mesh sleeve, thereby applying a certain pressing force to the mesh sleeve; when the mesh sleeve and the corrugated tube body complete the mesh pressing, just rotate and loosen the two tension adjustment rings to drive the two semicircular pressing rings to open relatively in the middle through hole, so that the mesh ring pressing assembly can be taken out and no pressure is applied to the mesh sleeve anymore. According to the metal hoses of different diameters, the semicircular pressure rings of the matching diameter can be replaced on the pulley component, and the adjustment operation is convenient.

[0035] 7. In the metal hose meshing method provided by the present invention, the above-mentioned meshing installation equipment is used to perform the meshing process on the metal hose. First, the two ends of the corrugated tube body are locked by the rear end locking part and the second locking part, and then the mesh sleeve is put on the surface of the corrugated tube body, and the pulley part drives the mesh ring pressing assembly to push back and forth on the mesh sleeve surface several times, so that the mesh sleeve is tightly pressed on the corrugated tube body, and finally the clamping sleeve part is used to clamp the mesh sleeve on both ends of the corrugated tube body and cut off the excess mesh sleeve. At this point, the meshing process is completed, and then the corrugated tube body, the clamping sleeve part and the mesh sleeve are welded at the junction of the three to make a metal hose. Compared with the traditional meshing process, the metal hose meshing method using this technical solution can effectively improve the meshing process quality, reduce waste, save time in the meshing process while reducing labor, improve work efficiency, and has a wide range of applications.

These terms are intended solely to facilitate and simplify the description of the present invention and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific manner.

[0048] Example 1

[0049] This embodiment provides Figure 1-8 The net installation device for a metal hose is used to tightly fit the net sleeve 91 onto the corrugated tube body 9, comprising:

[0050] The supporting structure includes a fixed bracket 1 and a support rod 2 horizontally connected to the fixed bracket 1, and a corrugated tube body 9 is sleeved on the support rod 2;

[0051] The limit locking assembly includes a rear end locking member 3 and a front end locking member 4 which are relatively arranged on the support rod 2 through a connecting structure. The rear end locking member 3 and the front end locking member 4 can move relative to each other for a certain distance along the axial direction of the support rod 2 and keep the relative position locked; when the rear end locking member 3 and the front end locking member 4 are locked and limited toward each other at the two ends of the corrugated tube body 9, the net sleeve can be put on the corrugated tube body;

[0052] The mesh sleeve pushing device includes a pulley component 5 and a central through hole 51 arranged on the pulley component 5 for the corrugated tube body 9 to pass through, and a mesh ring pressing component 6 that is telescopically arranged between the pulley component 5 and the central through hole 51 around the central through hole 51. The mesh ring pressing component 6 is adapted to embrace and press against the mesh sleeve 91, and presses the mesh sleeve 91 onto the corrugated tube body 9 as the pulley component 5 moves back and forth along the axial direction of the support rod 2.

[0053] In the above embodiment, when the metal hose is assisted in the netting operation by the netting installation equipment, the corrugated tube body 9 is first set on the support rod 2, and the two ends of the corrugated tube body are locked when the rear end locking member 3 and the front end locking member 4 move relative to each other along the support rod 2, which plays a positioning role for the corrugated tube body 9 on the support rod 2, avoiding the many disadvantages of the corrugated tube body directly contacting the ground when the net is set. At this time, the net sleeve 91 is passed through the surface of the corrugated tube body, and then the pulley component 5 is used to drive the net ring to press The closing component 6 is sleeved on the outside of the corrugated tube body, and the mesh ring pressing component 6 adjusted to the appropriate aperture is embraced and fitted on the mesh sleeve 91. Then, the pulley component 5 is driven to slide back and forth along the axial direction of the support rod 2, driving the mesh ring pressing component 6 to push back and forth on the surface of the mesh sleeve, thereby straightening the wrinkled and uneven mesh sleeve 91 and pressing it tightly on the corrugated tube body. In this way, the wire mesh sleeve 91 and the corrugated tube body can be tightly fitted to improve the meshing process effect. Finally, just use a clamping sleeve to clamp the mesh sleeve 91 on both ends of the corrugated tube body. The mesh installation equipment using this technical solution can be applied to the mesh processing of metal hoses of different specifications. The tightness of the mesh is relatively uniform, ensuring the coaxiality of the mesh at both ends of the corrugated pipe body, and avoiding wrinkles, bumps and unevenness of the mesh on the pipe body, greatly improving the quality of the mesh process, thereby ensuring the identity of the product, reducing waste generation, and optimizing the entire mesh process flow, which not only reduces labor, but also greatly improves work efficiency, reduces manufacturing costs, and has good market benefits.

[0054] In order to ensure the positioning reliability of the bellows body on the support rod, combined with Figure 2-4As shown, the rear end locking member 3 is provided with a first protruding structure 31 for limiting one end of the bellows body 9, and the front end locking member 4 is provided with a second protruding structure 41 set at the same height as the first protruding structure 31 and used to limit the other end of the bellows body 9. The two ends of the bellows body 9 are respectively sleeved on the first protruding structure 31 and the second protruding structure 41, so that an annular gap is formed between the bellows body 9 and the support rod 2. In this structural arrangement, the size of the first protruding structure 31 and the second protruding structure 41 is the same as the size of the two ends of the bellows body 9. The port sizes are roughly matched, and the first protrusion structure 31 and the second protrusion structure 41 play a positioning and supporting role on the two ends of the corrugated tube body 9, and then the two ends of the corrugated tube body 9 can be limited and locked by adjusting the rear end locking piece 3 and the front end locking piece 4. This structural setting forms an annular gap between the corrugated tube body 9 and the support rod 2, which can avoid extrusion and friction between the corrugated tube body 9 and the support rod 2 during the netting and tightening process, play a protective role for the tube body, and the netting installation is more evenly stressed. This installation method can also effectively ensure the coaxiality of the two ends of the corrugated tube body 9.

[0055] As a preferred embodiment, refer to Figure 2 The first protruding structure 31 and the second protruding structure 41 are arc-shaped limiting bosses provided on the side surfaces of the rear end locking member 3 and the front end locking member 4, respectively. The port of the bellows body 9 is just fitted onto the limiting bosses, and its two ends are limited and blocked by the rear end locking member 3 and the front end locking member 4. The installation force is more stable, and no deflection or shaking occurs, thereby ensuring the coaxiality of the two ends of the bellows body 9. In order to increase the contact distance between the limiting bosses and the ports of the bellows body 9, a round rod portion 34 can be provided along the axial extension of the arc edge of the limiting boss, and the round rod portion 34 is aligned with the arc edge of the limiting boss. It should be understood that since multiple forces will be applied to the bellows body 9 during the process of meshing and pulling the net, it is easy to deform and bend if the centers of the two ends of the tube body are not aligned. Therefore, under the condition of ensuring the coaxiality of the two ends of the bellows body 9, the meshing process quality of the product and the pressure-bearing performance of the wire mesh sleeve 91 can be effectively improved.

[0056] As an alternative to the above method, refer to Figure 3The first protruding structure 31 and the second protruding structure 41 respectively include at least one pair of limiting columns symmetrically arranged on the rear end locking member 3 and the front end locking member 4 about the axis of the support rod 2, wherein the rear end locking member 3 and the front end locking member 4 are respectively disc-shaped, and the distance between the connecting line of each pair of limiting columns passing through the axis is just adapted to the port diameter of the corrugated tube body 9. This design allows the two end ports of the corrugated tube body 9 to respectively fit against the multiple pairs of limiting columns of the first protruding structure 31 and the second protruding structure 41, thereby playing a positioning and supporting role for the two ends of the corrugated tube body 9, and having good installation stability. Those skilled in the art can make a choice of the specific arrangement of the first protruding structure 31 and the second protruding structure 41 based on the above description, and other equivalent embodiments will not be described one by one here.

[0057] The following combination Figure 1-5 The specific setting methods of the rear end locking piece and the front end locking piece are described in detail:

[0058] The middle part of the rear end locking member 3 is provided with a sliding hole slidably connected to the support rod 2. The connecting structure includes an annular platform 32 formed by extending along the axial direction of one end of the sliding hole, and a fixing hole 33 radially penetrating the annular platform 32, and a fastener fastened through the fixing hole 33 to keep the rear end locking member 3 and the support rod 2 fixedly connected. The fastener can preferably be a top screw structure or a screw structure. It can be seen that after the rear end locking member 3 moves a certain distance on the support rod, it is fastened to the support rod by the fastener so that the rear end locking member 3 can no longer be displaced. ; In addition, the connecting structure also includes a threaded section 21 extending along the axial direction of the support rod 2 and arranged at the front end of the support rod 2, and a threaded sleeve penetrating the middle of the front end locking piece 4. A truncated cone-shaped limiting section is connected between the support rod 2 and the threaded section 21. The front end locking piece 4 is movably arranged on the support rod 2 through the cooperation of the threaded sleeve and the threaded section 21. When the front end locking piece 4 moves along the threaded section 21 and is blocked by the limiting section, it means that the front end locking piece 4 has reached the end of the threaded section 21, so as to limit the front end locking piece 4 from continuing to move toward the side close to the front end locking piece.

[0059] The front end locking piece 4 is screwed into the front end of the support rod 2 through the threaded sleeve and the threaded section 21, and gradually moves closer to the side of the rear end locking piece 3. The front end locking piece 4 is arranged on the support rod 2 by a threaded structure and has a self-locking effect of the thread. The rear end locking piece 3 and the front end locking piece 4 are moved relative to each other for a certain distance and then pressed against the two ends of the corrugated tube body 9, which plays a limit locking role on the corrugated tube body 9 sleeved on the support rod 2, and effectively avoids the corrugated tube body 9 from sliding with the mesh sleeve 91 when the mesh sleeve 91 is sleeved or tightened. This connection structure is simple in design, and is convenient for installation and disassembly of the corrugated tube body 9 on the support rod 2, with reliable cooperation and easy and labor-saving operation.

[0060] like Figure 1 As shown, the fixed bracket 1 is composed of a mounting base 11 and a fixing frame 12 vertically connected, and a reinforcing rib plate is connected between the mounting base and the fixing frame 12 to enhance the structural strength between the mounting base 11 and the fixing frame 12. The rear end of the support rod 2 is fixed on the fixing frame 12, and the front end thereof is for the corrugated tube body 9 to pass through. The metal hose assembly can be lifted up by the cooperation of the fixed bracket 1 and the support rod 2, saving workers the need to repeatedly lift the heavy tube body and other heavy processes. The traditional bracket-free netting process requires 4-5 people to operate, while the netting process of this embodiment only requires 2-3 people to easily complete the netting process, thereby reducing labor.

[0061] The support rod 2 is provided with a polyurethane protective sleeve 23, which can protect the corrugated tube body 9 when the corrugated tube body 9 is installed and removed from the equipment on the support rod 2. This flexible polyurethane can effectively prevent the thin-walled corrugated tube body 9 from being damaged and has good protection.

[0062] In order to pre-tighten the mesh on the corrugated pipe body, Figure 1As shown, the net sleeve 91 installation device of this embodiment also includes a motor assembly 7 for driving the pulley component 5 to slide back and forth, and two net pulling hooks 8 for hooking and pulling at both ends of the net sleeve 91. The two net pulling hooks 8 can be used to pre-tighten the net sleeve 91 mounted on the corrugated tube body 9. The motor assembly 7 is respectively connected to the pulley component 5 and the net pulling hook 8 through the motor tow hook 71. The motor assembly 7 can be composed of two driving motors and are relatively arranged at both ends of the support rod 2, so that the two net pulling hooks 8 can be relatively tightened, or the pulley component 5 can be driven to perform reciprocating motion. With this structural arrangement, after the mesh sleeve 91 is inserted into the surface of the corrugated tube body, the two mesh hooks 8 are driven by the motor assembly 7 to relatively tighten the two ends of the mesh sleeve, thereby pre-tightening the mesh sleeve 91 on the surface of the corrugated tube body, making it convenient for the subsequent pulley component 5 to drive the mesh ring pressing component 6 to perform a reciprocating pushing action on the surface of the mesh sleeve, thereby tightly pressing the mesh sleeve onto the corrugated tube body. During this movement process, the pulley component is also driven to perform reciprocating movement by the motor assembly 7, and the force is applied more evenly and steadily, thereby reducing the intensity of manual labor, saving manpower, and improving work efficiency.

[0063] The following combination Figure 6-8 The specific setting method of the pulley parts and the net ring pressing assembly is described in detail:

[0064] The pulley component 5 includes a pulley frame provided with the central through hole 51, and an inner cavity arranged in the pulley frame for installing and accommodating the net ring pressing assembly 6, and a traction steel rope 52 arranged on the pulley frame and connected to the motor tow hook 71, and the motor tow hook 71 of the motor assembly 7 is hooked on the traction steel rope 52.

[0065] The mesh ring pressing assembly 6 includes two semicircular pressure rings 61 that are relatively movably arranged in the inner cavity, and two tension adjustment rings 62 that are rotatably arranged on the side edges of the pulley frame and respectively connected to the two semicircular pressure rings 61. The two semicircular pressure rings 61 are relatively provided with two arc clamping grooves, and the two tension adjustment rings 62 are used to adjust and drive the two semicircular pressure rings 61 to approach each other or separate from each other in the middle through hole 51. The advantage of such a design is that, by rotating and tightening the two tension-adjusting rings 62, the two semicircular pressure rings 61 are driven to fit together in the middle through hole 51 and tightly press against the surface of the mesh sleeve 91, thereby applying a certain pressing force to the mesh sleeve 91; when the mesh sleeve 91 and the corrugated tube body 9 complete the mesh pressing, just rotate and loosen the two tension-adjusting rings 62 to drive the two semicircular pressure rings 61 to open relatively in the middle through hole 51, so that the mesh ring pressing assembly 6 can be taken out and no pressure is applied to the mesh sleeve 91 any more. According to the metal hoses of different diameters, the semicircular pressure rings 61 of the matching diameter can be replaced on the pulley component 5, and the adjustment operation is convenient.

[0066] Example 2

[0067] This embodiment provides a method for wrapping a metal hose with a mesh. Figure 6-8 As shown, the following steps are included when using the netting installation device for the metal hose described in Example 1 to net the corrugated pipe body:

[0068] Step 1: Sleeve the bellows 9 onto the support rod 2, and position the bellows 9 on the support rod 2 by moving the rear end locking piece 3 and the front end locking piece 4 along the axial direction of the support rod 2 and locking them at both ends of the bellows 9;

[0069] Step 2: Put the mesh 91 on the surface of the corrugated tube body 9, select a mesh ring pressing assembly 6 of appropriate size and install it on the pulley component 5, push the pulley component 5 to hug the mesh ring pressing assembly 6 on the corrugated tube body 9 covered with the mesh 91, and adjust the mesh ring pressing assembly 6 to fit tightly with the surface of the mesh 91;

[0070] Step 3: Drive the pulley component 5 to move back and forth along the axial direction of the support rod 2, and drive the mesh ring pressing component 6 to push back and forth on the surface of the mesh sleeve 91 several times, so that the mesh sleeve is tightly pressed on the corrugated tube body 9.

[0071] Step 4: Use the clamping sleeve components to cover the two ends of the corrugated tube body 9 to clamp the mesh sleeve 91, so that the clamping sleeve component, the mesh sleeve 91 and the corrugated tube body 9 are tightly connected, and cut off the excess mesh sleeve 91 at the clamping sleeve.

[0072] When using the above-mentioned net installation equipment to carry out the netting process on the metal hose, if Figure 7 As shown, first lock the two ends of the bellows body 9 by the rear end locking member 3 and the second locking member, and Figure 8 As shown, the mesh sleeve 91 is then put on the surface of the bellows body 9, and the pulley component 5 drives the mesh ring pressing assembly 6 to push back and forth on the mesh sleeve surface several times, so that the mesh sleeve is tightly pressed on the bellows body, and finally the clamping sleeve component is used to clamp the mesh sleeve at both ends of the bellows body 9 and cut off the excess mesh sleeve. At this point, the meshing process is completed, and then the bellows body 9, the clamping sleeve component and the mesh sleeve 91 are welded at the junction of the three to obtain a metal hose. Compared with the traditional meshing process, the metal hose meshing method using this technical solution can effectively improve the quality of the meshing process, reduce waste, reduce labor while saving meshing process time, improve work efficiency, and has a wide range of applications.

[0073] As a preferred embodiment, in step one, the two ends of the bellows body 9 are positioned against the first protruding structure 31 of the rear end locking piece 3 and the second protruding structure 41 of the front end locking piece 4, respectively. The first protruding structure 31 and the second protruding structure 41 are set at the same height and adapted to the size of the port of the bellows body 9, thereby forming an equidistant annular gap between the bellows body and the support rod. This design keeps the coaxiality of the two ends of the bellows body consistent, which is beneficial to improving the quality of the meshing process.

[0074] Further preferably, in the step 2, two net hooks 8 are used to pull at both ends of the net sleeve 91, and the net sleeve 91 that is sleeved on the bellows body 9 is pre-tensioned. The two net hooks 8 are tightened under the drive of the motor assembly 7, and the net sleeve 91 is pre-tensioned to make it relatively flat on the surface of the bellows body 9; and in the step 3, the pulley component 5 can be driven by the motor assembly 7 to move back and forth along the axial direction of the support rod 2, so that the net sleeve 91 is tightly pressed on the bellows body 9 by the reciprocating pushing action of the net ring pressing component 6, and before the installation of the ferrule component process, the motor is turned on to tighten the two net hooks again, and the net sleeve covering the surface of the bellows body is finally tightened, so that the tight sealing is better. Finally, the fastening ferrule component is installed at both ends of the bellows body 9, and the redundant wire mesh sleeve 91 is cut off along the port position of the ferrule component, thus completing the netting process. In order to prevent the ferrule from being detached from the mesh again, argon gas shielded welding can be used to perform welding processing on the junction of the bellows body, the wire mesh sleeve 91 and the mesh sleeve 91, so as to reliably assemble them into an integrated structure. Then, the front end locking piece 4 is unscrewed, and the bellows body 9 with the mesh is removed from the support rod 2 to prepare for the next bellows body to be meshed.

[0075] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
