Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated pipe crimping, in particular to a pipe clamping crimping device for corrugated pipe connection. Background Art

[0002] At present, stainless steel compression fittings and their fixtures are mainly used for stainless steel pipe connections and are widely used in various engineering fields. Their standard parts comply with GB / T19228.1-2011 standards, and related extrusion dies, pressure pliers and other supporting tools are also popular in the market and are widely used.

[0003] However, there is no compression fitting assembly on the market that can be used to connect stainless steel bellows. The connection method of stainless steel bellows mainly adopts thread, and the thread connection method has the following defects:

[0004] 1. High cost: The connection of bellows usually requires the use of nuts, joints, flanges and other parts to achieve a close fit. These additional parts increase the material cost; the end of the bellows needs to be used with nuts, external thread joints, flanges and other parts, which increases the complexity and cost of the production process. Precision thread processing requires high-precision machine tools and processes, which may lead to higher manufacturing costs;

[0005] 2. Low efficiency: Threaded connections require tightening nuts one by one, which is much more time-consuming than other quick connection methods (such as quick connectors, clamps or crimping). In large projects or situations where a large number of connections are required, this will significantly reduce work efficiency. In addition, threaded connections rely on close contact between threads and appropriate gaskets to ensure sealing, and improper operation can easily lead to leakage. Utility Model Content

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a pipe clamping device for corrugated pipe connection, which solves the problem that the threaded connection method of stainless steel corrugated pipes in the prior art not only leads to high cost but also low efficiency.

[0007] To achieve the above-mentioned purpose, according to an embodiment of the first aspect of the utility model, a tube crimping device for connecting a corrugated pipe is provided, comprising a driving part of a squeezing tool, on which a clamp mechanism for squeezing an assembled pipe is installed;

[0008] The clamp mechanism includes a clamp base, an outer clamp jaw, an inner clamp jaw, and an extrusion die. The clamp base is installed on the driving part. The inner clamp jaw is slidably inserted into the clamp base, and the inner clamp jaw is controlled by the driving part to advance.

A surrounding area that can be sleeved on the assembled pipe fitting is formed between the outer clamp jaw and the inner clamp jaw. The extrusion die is installed in the surrounding area and is used to extrude the extrusion end of the assembled pipe fitting.

[0009] As a further technical solution of the present invention, the assembled pipe fitting includes a corrugated pipe and a crimped pipe fitting. The crimped pipe fitting is sleeved at one end of the corrugated pipe. The extrusion end of the assembled pipe fitting includes a bulging part located at a position close to the end of the crimped pipe fitting.

[0010] As a further technical solution of the present invention, the extrusion die includes a plurality of extrusion blocks respectively installed on the opposite sides of the outer clamp jaw and the inner clamp jaw. The plurality of extrusion blocks on the outer clamp jaw and the inner clamp jaw are evenly distributed. The extrusion block includes an arc-shaped extrusion part provided with an arc-shaped biting groove, a limiting part, and a mounting part with a clamping block. The limiting part is connected between the mounting part and the arc-shaped extrusion part.

[0011] As a further technical solution of the present invention, the inner clamp jaw is composed of an inner jaw clamping part and a plugging part. The outer clamp jaw is composed of an outer jaw clamping part and grooves at both ends. The inner jaw clamping part and the outer jaw clamping part are respectively composed of a horizontal part and a plurality of inclined parts symmetric about the horizontal part. Card slots for clamping the clamping block are formed on the side walls of the horizontal parts of the inner jaw clamping part and the outer jaw clamping part, and sliding grooves for the clamping block to slide into are formed on the side walls of the inclined parts of the inner jaw clamping part and the outer jaw clamping part. A detachable limiting pin is penetrated in the sliding groove, and the limiting pin is used to limit the position of the clamping block in the sliding groove.

[0012] As a further technical solution of the present invention, a convex block extending into the groove is fixedly installed at the end of the clamp base. A pin is installed between the convex block and the groove, and the convex block is rotationally connected to the groove through the pin. A socket for the plugging part to pass through is penetrated in the clamp base, and limiting grooves are formed at the opposite side walls on both sides of the socket. A reset mechanism corresponding to the limiting groove is installed on both sides of the plugging part.

[0013] As a further technical solution of the present invention, a recessed part for limiting the insertion depth of the corrugated pipe is provided at the middle position of the crimped pipe fitting. A matching sealing ring is embedded in the bulging part, and the sealing ring corresponds to the valley part of the corrugated pipe.

[0014] As a further technical solution of the present utility model, the reset mechanism includes a spring limit block, a first screw, a cylindrical boss, and a reset spring. The spring limit block is fixedly installed on the side wall of the insertion part through the first screw. The boss is installed at one end of the spring limit block close to the limit groove. One end of the spring limit block extends into the limit groove. One end of the reset spring is sleeved on the boss, and the other end of the reset spring is connected to the end of the limit groove.

[0015] As a further technical solution of the present utility model, fixed blocks with mounting holes are symmetrically connected to one side of the clamp seat away from the outer clamping jaw. A fixing pin passing through the mounting hole is disposed through the driving part. One end of the fixing pin is in contact with the outer side wall of the driving part, and a handle part in contact with the outer side wall of the driving part is sleeved on the other end of the fixing pin. The handle part and the fixing pin are connected by a second screw.

[0016] As a further technical solution of the present utility model, a guiding through groove for the fixing pin to pass through is disposed through the inner clamping jaw. The inner clamping jaw is slidably connected to the fixing pin through the guiding through groove.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. In the present utility model, the driving part facilitates the pushing of the inner clamping jaw along the clamp seat, facilitating the extrusion die mounted on the inner clamping jaw to approach the extrusion die mounted on the outer clamping jaw, thereby facilitating the extrusion of the extrusion end of the pipe fitting, enabling the crimped pipe fitting to be tightly extruded on the corrugated pipe, and realizing the rapid crimping of the stainless steel corrugated pipe. Compared with the traditional threaded connection method, it not only effectively reduces costs but also is beneficial to improving the docking efficiency.

[0033] The technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0034] As Figures 1-12 shown, a pipe clamping and crimping device for corrugated pipe connection includes a driving part 1 of an extrusion tool, and a clamping mechanism 3 for extruding an assembled pipe fitting 2 is installed on the driving part 1; the clamping mechanism 3 includes a clamping seat 31, an outer clamping jaw 32, an inner clamping jaw 33 and an extrusion die 34. The clamping seat 31 is installed on the driving part 1, and the inner clamping jaw 33 is slidably inserted into the clamping seat 31, and the inner clamping jaw 33 is controlled by the driving part 1 to advance. In order to facilitate shielding and protection of the inner clamping jaw 33, in this embodiment, baffles 314 are symmetrically installed on both sides of the clamping seat 31. The outer clamping jaw 32 is installed at one end of the clamping seat 31 away from the driving part 1. A surrounding area that can be sleeved on the assembled pipe fitting 2 is formed between the outer clamping jaw 32 and the inner clamping jaw 33. The extrusion die 34 is installed in the surrounding area, and the extrusion die 34 is used to extrude the extrusion end of the assembled pipe fitting 2.

[0035] It should be noted that the extrusion tool and its driving part 1 are mature prior arts. The extrusion tool can be any one of an electric hydraulic crimping tool, a pneumatic crimping tool, a battery-driven crimping tool, and a mechanical crimping tool. The driving part 1 is a part of the extrusion tool. When in use, the extrusion tool is powered on, and the inner clamping jaw 33 is pushed along the clamping seat 31 by the cooperation of the driving part 1. The outer clamping jaw 32 connected to the clamping seat 31 remains stationary. The extrusion die 34 installed on the inner clamping jaw 33 and the outer clamping jaw 32 can be used to crimp the extrusion end of the assembled pipe fitting 2. It can be understood that the movement mode of the inner clamping jaw 33 and the outer clamping jaw 32 is not limited in this application. The above only provides a specific movement mode for reference. In addition, the inner clamping jaw 33 and the outer clamping jaw 32 rotate coaxially around a point for circumferential crimping or clamping (circumferential crimping is applicable to large-diameter pipes, and clamping is applicable to small-diameter pipes), which is also within the protection scope of this application. It should be noted that when the inner clamping jaw 33 and the outer clamping jaw 32 perform circumferential crimping or clamping, the inner clamping jaw 33 and the outer clamping jaw 32 are arc-shaped structures.

[0036] As Figures 11-12As shown, it can be understood that the present application does not limit the specific structure and dimensions of the assembled pipe fitting 2. Only a specific structure is provided below for reference. The assembled pipe fitting 2 includes a corrugated pipe 21 and a crimped pipe fitting 22. The crimped pipe fitting 22 is sleeved on one end of the corrugated pipe 21. The extrusion end of the assembled pipe fitting 2 includes a bulge portion 221 located at a position near the end of the crimped pipe fitting 22. A recessed portion 222 for defining the insertion depth of the corrugated pipe 21 is provided at the middle position of the crimped pipe fitting 22. A matching sealing ring 223 is embedded in the bulge portion 221, and the sealing ring 223 corresponds to the valley portion 211 of the corrugated pipe 21. In this embodiment, when the end of the corrugated pipe 21 abuts against the recessed portion 222, the third valley portion 211 of the corrugated pipe 21 faces the sealing ring 223.

[0037] It should be noted that bulge portions 221 are respectively provided at the pipe walls near both ends of the crimped pipe fitting 22. The crimped pipe fitting 22 can be assembled on a conventional metal pipe and a stainless steel corrugated pipe 21 corresponding to its size. It is worth noting that when the crimped pipe fitting 22 is used to connect a conventional metal pipe and a corrugated pipe 21 of the same specification, the size of the bulge portion 221 corresponding to the corrugated pipe 21 is larger than that of the bulge portion 221 corresponding to the conventional metal pipe. That is to say, the bulge degree of the bulge portion 221 corresponding to the corrugated pipe 21 is greater. Through this new type of crimped pipe fitting 22, a plumbing worker can assemble the stainless steel corrugated pipe 21 and the conventional metal pipe at the same time, enabling the plumbing worker to easily construct not only a traditional smooth pipe pipeline system, but also a system combining the corrugated pipe 21 and the smooth pipe, or even a pipeline system completely composed of the corrugated pipe 21, thus providing great convenience for the diversity and adaptability of the pipeline system.

[0038] As Figures 8-10 shown, it can be understood that the present application does not limit the number of extrusion blocks 341 installed on the outer clamping jaw 32 and the inner clamping jaw 33. Only a specific structure is provided below for reference. The extrusion die 34 includes extrusion blocks 341 respectively installed on the opposite sides of the outer clamping jaw 32 and the inner clamping jaw 33 (three extrusion blocks 341 are respectively installed on the outer clamping jaw 32 and the inner clamping jaw 33), and the three extrusion blocks 341 located on the outer clamping jaw 32 and the inner clamping jaw 33 are evenly distributed; the extrusion block 341 includes a curved surface extrusion portion 3412 provided with a curved biting groove 3411, a limiting portion 3413, and an installation portion 3415 with a clamping block 3414. In this embodiment, the curved surface extrusion portion 3412 is used to extrude the outer pipe wall of the crimped pipe fitting 22, the curved biting groove 3411 is used to extrude the bulge portion 221, and the limiting portion 3413 is connected between the installation portion 3415 and the curved surface extrusion portion 3412.

[0039] It should be noted that the extrusion die 34 will vary according to the size of the pipe to be connected. Considering universality, for the corrugated pipes 21 and conventional metal pipes of the same specification, the same set of extrusion dies 34 should be used as much as possible. This not only helps to reduce costs but also simplifies the operation process. A rubber sleeve (not marked in the figure) is commonly sleeved on the three extrusion blocks 341 located on the outer clamping jaw 32 and the inner clamping jaw 33. The rubber sleeve facilitates combining the three extrusion blocks 341 together and improves the disassembly and assembly efficiency.

[0040] As Figures 2-4 and Figure 6 shown, it can be understood that the specific shapes and dimensions of the inner clamping jaw 33 and the outer clamping jaw 32 of the present application are not limited. The following only provides a specific structure for reference. The inner clamping jaw 33 is composed of an inner jaw clamping portion 331 and a plugging portion 332. The outer clamping jaw 32 is composed of an outer jaw clamping portion 321 and grooves 322 at both ends. The inner jaw clamping portion 331 and the outer jaw clamping portion 321 are respectively composed of a horizontal portion and two inclined portions symmetrical about the horizontal portion. A clamping groove 4 for clamping the clamping block 3414 is provided on the side wall of the horizontal portion of the inner jaw clamping portion 331 and the outer jaw clamping portion 321, and a sliding groove 5 for the clamping block 3414 to slide into is provided on the side wall of the inclined portion of the inner jaw clamping portion 331 and the outer jaw clamping portion 321. A detachable limit pin 6 is penetrated in the sliding groove 5, and the limit pin 6 is used to limit the position of the clamping block 3414 in the sliding groove 5.

[0041] It should be noted that the clamping groove 4 is used to conveniently position the clamping block 3414 installed on the horizontal portion, and the limit pin 6 is used to conveniently limit the position of the clamping block 3414 installed in the sliding groove 5 of the inclined portion. By controlling the sliding of the clamping block 3414 in the sliding groove 5, the extrusion die 34 can be disassembled and replaced as needed. When the inner clamping jaw 33 squeezes and approaches the outer clamping jaw 32, the extrusion blocks 341 located on the inclined portion of the inner clamping jaw 33 and the inclined portion of the outer clamping jaw 32 will drive the clamping block 3414 to slide along the sliding groove 5, so that the extrusion blocks 341 on the inclined portion move towards the center of the assembled pipe fitting 2 until the limiting portions 3413 of two adjacent extrusion blocks 341 on the inner clamping jaw 33 and the outer clamping jaw 32 are in contact with each other.

[0042] As Figures 2-3 and Figure 6As shown, a convex block 311 extending into the groove 322 is fixedly installed at the end of the clamp seat 31. A pin 7 is installed between the convex block 311 and the groove 322, and the convex block 311 is rotatably connected to the groove 322 through the pin 7. On the side of the clamp seat 31 away from the outer clamping jaw 32, fixed blocks 313 with mounting holes are symmetrically connected. A fixing pin 9 passing through the mounting hole is disposed through the driving part 1. One end of the fixing pin 9 is in contact with the outer side wall of the driving part 1, and a handle part 10 in contact with the outer side wall of the driving part 1 is sleeved on the other end of the fixing pin 9. The handle part 10 is connected to the fixing pin 9 through a second screw 11. A guiding through groove 333 for the fixing pin 9 to pass through is disposed through the inner clamping jaw 33, and the inner clamping jaw 33 is slidably connected to the fixing pin 9 through the guiding through groove 333.

[0043] It should be noted that when disassembling and assembling the extrusion die 34, after removing one pin 7, the outer clamping jaw 32 can be deflected along the clamp seat 31 by using the other pin 7 that is not disassembled, so as to open the enclosure area between the outer clamping jaw 32 and the inner clamping jaw 33, facilitating the disassembly, assembly and replacement of the extrusion die 34 as required; after inserting the inner clamping jaw 33 into the clamp seat 31, the clamp seat 31 can be conveniently fixed and installed on the driving part 1 by using the fixing pin 9. In addition, the fixing pin 9 cooperating with the guiding through groove 333 on the inner clamping jaw 33 can not only slide-guide the inner clamping jaw 33 to improve the stability of the advancement of the inner clamping jaw 33, but also conveniently limit the sliding stroke of the inner clamping jaw 33.

[0044] As Figures 3-7 shown, a socket for the insertion part 332 to pass through is penetrated and opened on the clamp seat 31, and limiting grooves 312 are opened at the opposite side walls on both sides of the socket. Reset mechanisms 8 corresponding to the limiting grooves 312 are installed on both sides of the insertion part 332, facilitating the reset of the inner clamping jaw 33;

[0045] The reset mechanism 8 includes a spring limiting block 81, a first screw 82, a boss 83 and a reset spring 84. The spring limiting block 81 is fixedly installed on the side wall of the insertion part 332 through the first screw 82. The boss 83 is installed at one end of the spring limiting block 81 close to the limiting groove 312. One end of the spring limiting block 81 close to the boss 83 partially extends into the limiting groove 312. One end of the reset spring 84 is sleeved on the boss 83, and the other end of the reset spring 84 is connected to the end of the limiting groove 312.

[0046] It should be noted that when the inner clamping jaw 33 advances towards the outer clamping jaw 32, it will drive the spring limiting block 81 to slide along the limiting groove 312, thereby compressing the reset spring 84 in the limiting groove 312. The compressed reset spring 84 is convenient for generating a reaction force on the spring limiting block 81, thus facilitating the subsequent reset of the inner clamping jaw 33.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
