Description

Pipe Crimp Fasteners {Apparatus for press-connecting pipes}

The present invention relates to a pipe crimp fastener configured to fasten both pipes by pressing a large diameter pipe outer circumferential surface into which a small diameter pipe is inserted.

In general, when connecting a pipe for outdoor and indoor plumbing of metal, a small diameter pipe is inserted into a large diameter pipe and then welded to the insertion part. However, in many cases, a thin pipe is used for cost reduction. Connecting the pipe by welding has a problem that the economic efficiency is greatly reduced because too many defects.

In addition, the classic fastening method of fastening two pipes using threaded connection pipes is not easy to move the screws for fastening the connection pipes to thin metal pipes, and the joints are easily deformed during the fastening process. Given that it could be difficult to apply realistically.

Accordingly, many crimping fastening methods and crimping fastening tools for fastening two pipes by crimping the outer circumferential surface of a large diameter pipe into which a small diameter pipe is inserted have been proposed. According to the crimping fastening method, a thinner thickness is compared with the aforementioned methods. It is effective to fasten the metal pipe more easily and simply.

The pipe crimping device shown in FIGS. 1 and 2 is disclosed in Korean Patent No. 10-0578450 (2006.05.03), wherein the first and second fixing blocks 10 and 12 and the first and second fixing blocks ( 10, 20 and a plurality of chain links 14 which are rotatably connected to each other, and are coupled to the inner surface of each chain link 14 by a coupling means, and an arcuate groove is formed on the inner circumferential surface of the pipe to be crimped. A plurality of circular arc blocks 16 in contact with the outer circumferential surface is provided.

In addition, the pipe crimping device of FIGS. 1 and 2 also has connecting links 15 for rotatably connecting adjacent circular arc blocks 16, and a plurality of circular arc blocks 16 being crimped on the outer circumferential surface of the pipe. It is configured to include an operating means for operating the first and second fixing blocks (10, 12) in the direction or to release the pressing.

In addition, the pipe compression fastening device is provided with a connecting piece 13 to prevent the separation of the circular arc blocks (16).

As described above, the conventional pipe crimp fastening device has a large number of parts for crimping pipes, which causes a complicated part output and assembly process for producing a product. In addition, the conventional pipe crimp fastening device has a problem that the parts may be damaged by the force applied during the crimping because many parts are used for crimping and fixing in an assembled state.

3 is a view illustrating a pipe compression fastening device for connecting the pipe compression fastening device of FIGS. 1 and 2 to pressurize a force for compressing a pipe.

The illustrated pressure crimping device for pipe crimping actuates the first and second fixing blocks 10 and 12 in a direction in which the plurality of circular arc blocks 16 shown in FIG. . The press fitting device for crimping the pipe is rotatably connected to the fixing plate 24 by hinge pins 22 and 23 and connected to the first and second fixing blocks 10 and 12 of FIG. The first and second main blocks 20 and 21 and cylinders (not shown) for rotating the other ends of the first and second main blocks 20 and 21 to be adjacent to or far from each other are provided.

A hook hole 25 is formed at one end of the first main block 20 so as to be rotatably pin-connected with the connection hole 17 of the first fixing block 10 of FIG. 1, and the second main block 21. One end of the engaging groove 26 is formed to be coupled or detachable to the engaging pin 18 of the second fixing block 12.

Accordingly, the first fixing block 10 compresses the pipe while detaching only the second fixing block 12 with respect to the second main block 21 while being fixed to the first main block 20. When the two main blocks 20 and 21 are rotated by a cylinder, the first and second fixed blocks 10 and 12 are moved to be close to or away from each other, thereby causing each arc block 16 to compress the pipe.

As such, the connection hole 17 and the locking pin 18 of the conventional pipe compression fastening device are connected in a straight line with the locking hole 25 and the locking groove 26 of the pipe compression fastening device. . Therefore, when performing the pipe pressure tightening operation using the conventional pipe compression fastening device and the pipe compression fastening device, there is a problem that the pipe crimping operation is impossible in a narrow space where the straight line work is impossible.

In addition, when pressing the pipe by using the pressure device of the configuration described above, since each arc block 16 does not press the pipe with a uniform force, a gap may occur in the crimping portion, which may cause leakage. Since a large force is required to compress the pipe, there is a problem that an expensive heavy hydraulic device must be used.

Moreover, in order to wind the pipe crimping device to the pipe, a chain-shaped block must be wound around the pipe, which is very inconvenient because a heavy load fastener must be installed with two hands to install the pipe in the correct position. There was a problem.

In addition, the pressure crimping device for pipe crimping of Figure 3 is the first and second main block (2) as the rollers are moved along the inclined surface 28 of the pressure device while the cylinder is installed at the end of the two rollers (not shown) 20 and 21, but as shown in FIG. 3, the inclined surface 28 of the pressurizing device is formed in an inclined straight line shape.

The roller (not shown) does not take a large load at the initial stage of entering the pipe for crimping the pipe, but as the roller proceeds into the pressurization device, the contact between the roller and the inclined surface 28 comes closer to the hinges 22 and 23, and accordingly, Increasingly large loads often resulted in breakage of the pressurizer, roller or cylinder.

The present invention has been made in order to solve the above problems, by pressing the pipe crimping fasteners using a pressure device (pliers) work by configuring the pipe fastening operation even if the pressurizing device and the fasteners are not located in a straight line It is an object of the present invention to provide a pipe crimp fastener that is easy and simple for pipe fastening even if the space is small.

In addition, when the pipe is crimped, the fastener is configured to apply a uniform force to the outer circumferential surface of the pipe, thereby providing a pipe crimp fastener that can crimp the pipe with a small force without causing a leak in the pipe compression part. It is an object of the present invention.

It is also an object of the present invention to provide a pipe crimp fastener that allows the operator to easily mount the crimp of high load to the pipe with little force.

The operation of the present invention configured as described above will be described in detail.

In order to crimp the pipe, the fastener 100 should be mounted on the pipe to be crimped. As shown in FIG. 5, the fastening block 170 is rotated by extracting the fastening pin 131a of the crimping block 170 to open the fastener 100, and the jaw 191 of the fastener 100 is located on the outer surface of the pipe. Insert and fasten the fastener 100.

In the process of mounting the fastener 100 to the pipe as described above, the pair of hooks 150 and the compression block 170 rotates and the fastener 100 is opened, and the fastener 100 is mounted on the pipe. Then, the fastener 100 is lifted and fixed to the pipe outer surface by the elasticity of the plate spring 101 bolted to the hook 150 and the hook spring 176 of FIG. 7.

Thereafter, the fastening block 170 is separated from the fastening pin 131a by rotating the lower die fastening groove 174 and the lower die 130 of the crimping block 170 to the pin 131a to mount the fastener 100. To complete.

As described above, the fastener 100 is mounted on the pipe, and the tooth 205 of the tongs 200 is inserted into the tooth groove 172 of the crimping block 170 as shown in FIG. 4, and is clamped by a pressurizer (not shown). Press 200.

As shown in FIGS. 4 and 9, the tongs 200 are elastically supported by the springs 208 and the first and second tongs blocks are formed on the tong fasteners 203 so that the curved roller contacts 207 face each other. 201, 202 is coupled to the pin 204, the pressurizer is configured with a pair of rollers 206 at the end of the cylinder linearly by oil, pneumatic or motor.

In the state of FIG. 4, when the cylinder goes straight, the roller 206 contacts the roller contact surface 207 of the forceps 200, enters the forceps 200, and opens the first and second forceps blocks 201 and 202, and the tooth 205. The pressing piece 171 of the pressing block 170 is pressed.

As the tooth 205 of the tongs 200 presses the crimping piece 171, the crimping block 170 rotates around the pin 154, and both sides of the lower side of the crimping block 170 and the pins 131 are coupled to each other. The die 130 ascends and compresses the pipe. At this time, the wing portion 195 formed by bending both sides of the jaw press 190 fastened to the hook 150 is in contact with the bent portions on both sides of the upper die 110 and the lower die 130, respectively, as described above. As the 130 is raised, the wing portions 195 of the jaw press 190 engaged with the hook 150 are tightened in the fastener 100 along the bent slopes of the upper and lower dice 110 and 130.

As described above, the jaw press 190 fastened to the upper and lower dice 110 and 130 and the hook 150 proceeds to the inside of the fastener 100, and the jaw 191 fastened to the jaw press 190 compresses the pipe. The pipe is tightened. In this process, the pair of jaws 191 fastened to the jaw press 190 are connected to each other by a spring 192, and each jaw 191 is connected to the inclined wing portion 195 of the jaw press 190. Since it is in contact with the jaw 191 as the crimping pipe, the back of the jaw 191 slides along the wing portion 195 of the jaw press 190 and the gap between the jaws 191 is narrowed and the pipe is crimped and fastened Make sure there are no gaps in the connections of the pipes.

After the pipe compression is completed, when the fastener 100 is removed, the pair of jaws 191 fastened to the jaw press 190 are opened again by a spring 192 connecting the jaws 191 to maintain a predetermined interval. .

As described above, the tongs 200 for pressing the fastener 100 are configured such that the roller contact surfaces 207 of the first and second tongs blocks 201 and 202 form a curved line, as shown in FIGS. 4 and 9. The curve of the roller contact surface 207 is configured such that the curvature gradually increases as it enters from the outside of the tongs 200.

This is to allow a constant load on the cylinder and the roller 207 when the roller 206 of the pressurizer cylinder presses the roller contact surface 207 of the forceps 200, and to compress the pipe with a small force. If the roller contact surface 207 is not curved but is inclined linearly, as the roller 206 of the pressurizer gradually proceeds to the inside of the tongs 200 (the roller gradually becomes the pin 204 of the tongs fixture 203). The closer the pressure is, the more the force acts on the roller 206 and the pressurizer by the principle of the lever, so the pressurizer must pressurize with greater force. This often causes breakage of the pressurizer, roller 206 and tongs 200.

However, if the roller contact surface 207 of the forceps 200 is configured in a curved shape as in the present invention, the curvature is gradually increased as it enters from the outside of the forceps 200 to the inside, and the roller 206 is the forceps 200 The roller 206 is in contact with the roller contact surface 207 having a large curvature as it progresses inward along the roller contact surface 207 of the pliers, thereby pressing the forceps 200 with a small force.

That is, in the initial stage when the roller 206 proceeds along the roller contact surface 207 of the tongs 200, the pressing stroke distance of the tooth 205 is long and rapid by the low speed roller contact surface 207. At the end of the roller 206 traveling along the roller contact surface 207 of the tongs 200, the roller 206 may have a short pressing stroke distance of the tooth 205 by the roller contact surface 207 having a large curvature. Since the pipe can be crimped with great force, the pipe can be crimped firmly with little force, and there is no fear of breakdown due to large load.

In addition, according to the present invention, the tooth 205 of the forceps 200 is formed in a spherical shape, and the tooth 205 is fastened to a pipe by configuring the tooth 205 to be inserted into a spherical tooth groove 172 and compressed. Since it can be crimped with tongs 200 in various directions, it is possible to conveniently proceed in a narrow work space.

The pipe crimp fastener according to the present invention has been described above.
