Description

Technical Field

[0001] The present application relates to the field of crimping machine repair and maintenance, and in particular to a crimping machine maintenance tool for flexible composite pipes. Background Art

[0002] The crimping machine is a hydraulic device used for crimping the joints of flexible composite high-pressure plastic conveying pipes. It compresses and deforms one end of the pipe through the pressure generated by the hydraulic system, making it tightly connected with the joint at the other end, thereby realizing the crimping of the pipe. During the working process, the crimping machine squeezes and fixes the pipe by moving the arc-shaped slider up and down, thereby completing the crimping operation.

[0003] Since the working environment of the crimping machine is generally contaminated by hydraulic oil and dust, it is easy to cause the arc slider in the crimping machine to wear and other undesirable phenomena, so the arc slider needs to be cleaned and maintained regularly. It is relatively easy to disassemble the arc slider of the crimping machine, but it is very difficult to assemble the arc slider due to the elastic force of the spring during assembly, and it usually needs to be returned to the factory for assembly, which leads to a long maintenance time for the crimping machine, high downtime costs, and high transportation costs for round-trip transportation.

[0004] In view of the above-mentioned related technologies, it is urgent to develop a tooling that can facilitate the installation of the arc-shaped slider in the crimping machine. Utility Model Content

[0005] In order to facilitate the installation of the arc-shaped slider of the crimping machine, the present application provides a crimping machine maintenance tool for flexible composite pipes.

[0010] The connecting assembly includes a telescopic member and a fixed block, wherein the fixed block is located outside the support ring and is connected to the support ring via the telescopic member. A slot structure for fixing the arc-shaped slider is provided on a side of the fixed block away from the support ring.

[0011] Optionally, the telescopic member includes a connecting screw and an adjusting nut. A through hole is formed on the support ring, and the connecting screw is inserted into the through hole.

[0017] 1. The present application fixes the arc-shaped slider of the crimping machine by setting a fixed block, and then drives the arc-shaped slider to extend through the telescopic member, so that the distance between the arc-shaped sliders is increased, and then the spring is installed between the arc-shaped sliders, and then the arc-shaped slider is driven to slide in the direction close to the support ring through the telescopic member, so as to reduce the distance between the arc-shaped sliders, so that the maximum outer circle between the arc-shaped sliders is reduced, and the spring is compressed at this time, and then the arc-shaped slider and the tooling are placed as a whole in the working area of ​​the crimping machine, and then the adjusting nuts on the connecting screw are evenly screwed to the outermost end of the connecting screw (the center direction of the circle), so that the arc-shaped slider expands to the maximum under the action of the spring elastic force and is tightly attached to the internal arc surface of the crimping machine, and the installation work is completed.

[0022] The following is combined with Figure 1-2This application is described in further detail.

[0023] The present application embodiment discloses a maintenance tool for a crimping machine for a flexible composite pipe. Figure 1 and Figure 2 A maintenance tool for a crimping machine for a flexible composite pipe includes a support ring 1 and a plurality of connection components.

[0024] Reference Figure 1 and Figure 2 In this embodiment, there are eight connecting components, and the eight connecting components are evenly distributed along the circumference of the support ring 1. In other embodiments, the number of connecting parts can also be three, five, six, etc., and the number can be freely selected according to the form of the accessories to be assembled, and the number does not serve as a limitation to the present application.

[0025] Reference Figure 1 and Figure 2 The connection assembly includes a telescopic member 2 and a fixed block 3. The telescopic member 2 includes a connecting screw 21 and an adjusting nut 22. Eight through holes 11 are radially penetrated on the support ring 1. The eight through holes 11 are evenly spaced along the circumference of the support ring 1. A connecting screw 21 of a connection assembly is installed correspondingly to a through hole 11. The connecting screw 21 is inserted into the through hole 11. One end of the connecting screw 21 away from the center of the support ring 1 is threadedly connected to the fixed block 3, and the other end is threadedly connected to the adjusting nut 22. The fixed block 3 and the two side surfaces perpendicular to the radial direction of the support ring 1 are both set as arc surfaces.

[0026] Reference Figure 1 and Figure 2 A slot structure for fixing the arc-shaped slider 4 is provided on the side of the fixed block 3 facing away from the support ring 1. In this embodiment, the slot structure is set as a dovetail groove 31. The slot structure in other embodiments can be set according to the specific form of the accessories to be installed. At the same time, other components can also be used to fix the arc-shaped slider 4, as long as the arc-shaped slider 4 and the fixed block 3 can be fixed.

[0027] The implementation principle of the crimping machine maintenance tooling for flexible composite pipes in the embodiment of the present application is as follows: when in use, first assemble the installation tooling, first thread the connecting screws 21 of the eight connecting components with the threaded holes on the back of the fixing block 3; then insert one end of the connecting screw 21 connected to the fixing block 3 into the corresponding through hole 11 of the support ring 1, and then thread the adjusting nut 22 with the connecting screw 21, so that the adjusting nut 22 is located at one end of the connecting screw 21 close to the center of the circle, thereby driving multiple fixing blocks 3 to be located on the same outer circle of the maximum diameter. Then fix the arc slider 4.

[0028] When fixing, clean the eight arc-shaped sliders 4 removed from the crimping machine, and install them on the fixed block 3 through the dovetail groove 31 connection method; then clean the compression springs 5 ​​between the arc-shaped sliders 4, and install them in the spring 5 holes on the eight arc-shaped sliders 4, and uniformly adjust the nuts on the connecting screws 21 to reduce the maximum outer circle of the arc-shaped slider 4 by 10-20mm. The purpose is to make the spring 5 have a certain elastic force after installation, so that it will not be in a free state, thereby preventing the spring 5 from falling off, and also preventing the fixed block 3 and the connecting screw 21 from sliding freely in the direction close to the center of the circle, thereby improving the installation stability of the arc-shaped slider 4. Then install the arc-shaped slider 4 with the crimping machine.

[0029] During installation, adjust the adjustment nut 22 on the tooling connection screw 21 again according to the size of the inner circle of the crimping machine, so that the outer diameter of the arc-shaped slider 4 is reduced to about 20mm smaller than the outer diameter of the inner circle of the crimping machine, and then put the installed and adjusted tooling into the inner circle of the crimping machine; then, evenly screw all the adjustment nuts 22 on the connection screw 21 to the outermost end of the connection screw 21 (the center direction of the circle), so that the arc-shaped slider 4 expands to the maximum under the elastic force of the spring 5 and fits tightly with the inner arc surface of the crimping machine. Finally, connect the end cover of the crimping machine with a 12.9-grade high-strength hexagonal bolt, and then use a hammer and a copper rod to slowly knock the tooling out of the crimping machine. At this time, the arc-shaped slider 4 of the crimping machine is installed.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
