Description

  The present invention relates to an electric flare processing machine suitable for flaring pipe tips having different diameters during piping work for an air conditioner or the like.

  Manual flare processing machines are generally used, but there is a disadvantage that a lot of burden is placed on workers' hands. Therefore, an electric flare machine is being manufactured. As this electric flare processing machine, for example, electric flare processing machines described in Patent Documents 1 to 4 have been proposed.

  In the electric swaging machine of Patent Document 1, a speed reduction device and a gear case are disposed at one end of an L-shaped frame, and a pipe chuck portion is disposed at the other end of the frame. The inner diameter of the part is enlarged by a swaging punch in the gear case.

  The electric flare tool of Patent Document 2 is a gun grip type in which the machining axis direction and the motor are parallel, and the clamping device employs screwing. That is, in Patent Document 2, a rotation drive shaft having an eccentric cone fixed at the tip, a screw shaft member screwed into a female screw portion connected to the rotation drive shaft, and the screw shaft member and the rotation drive shaft. An elastic member that is interposed therebetween and constantly urges the rotary drive shaft in one axial direction is provided. Moreover, the pipe clamp uses the clamp which inserts a pipe front-end | tip into the front-end | tip of an electric flare tool, and fixes it with a split plate and a fastening bolt with this state.

  The flare processing machine described in Patent Document 3 has a structure in which a processing axis direction and a motor are arranged in a straight axis direction, and a clamp device is provided with a fixing lever. The type of the pipe clamp device is a lever-fixed type, and one of the clamp bases provided in the main body is fixed and the other is a movable arm that can be opened and closed. And it is an apparatus which clamps a pipe with a fixed lever by arrange | positioning each one of the two split dies in a clamp base, closing a movable arm.

The electric flare tool disclosed in Patent Document 4 describes a machining system housing incorporating a screw body and a main shaft and a drive system housing incorporating a motor and a torque clutch provided separately.

  However, all of the conventional flare apparatuses have a common disadvantage. That is, it takes a lot of labor to install the pipe. That is, in piping work for an air conditioner or the like, it is necessary to process the end of a pipe that has already been arranged. At this time, all of the conventional flare apparatuses are configured such that the end of the pipe is directly attached to the end of the flare apparatus. Therefore, as a work procedure of the pipe, carry the flare device near the end of the pipe, insert the end of the pipe to be processed into the predetermined hole of this flare device, fix this pipe with the clamp, and then fix the eccentric cone. The pipe diameter is flared.

  Therefore, no matter how compact the conventional electric flare apparatus is, the pipe end is inserted into a part of the flare apparatus while the electric flare apparatus is lifted to a position where pipe processing is necessary, and this pipe is further connected. Fixing work was necessary. Moreover, in piping work for air conditioners and the like, since this work is performed at a high place where the air conditioner is installed, a great deal of labor is required in the preparation stage before actual flare processing.

  For example, in the electric swaging machine of Patent Document 1, a flare device is provided at one end of an L-shaped frame, and a vise-shaped pipe chuck portion is provided at the other end of the frame. The weight hinders pipe processing work at high altitudes.

  Also, in the electric flare tool of Patent Document 2, since a pipe tip is inserted into the tip of this electric flare tool and is fixed in this state using a split plate or a fastening bolt, It takes a lot of work to insert and fix the pipe end at the tip of the tool. In addition, the gun clip type electric flare tool is constructed in the order of cone, cone holder, spring, clutch device, and reduction gear along the machining axis direction of the flare machine, so the dimension in the straight axis machining direction becomes longer. ing. For this reason, when the pipe is to be machined in a narrow space, there arises a disadvantage that the length in the machining axis direction hinders the work.

  Furthermore, in the flare processing machine described in the cited document 3, the clamp device is provided with a fixing lever, but before fixing with the fixing lever, the end of the pipe can be inserted into one end of the flare processing machine and opened and closed. Those that require complicated operations such as tightening and fixing the movable arm to the lower clamp base provided on the main unit, and further rotating the fixing lever 180 degrees and then tightening and fixing by moving it in a perpendicular direction in another direction It is. Therefore, such an operation cannot simplify the pipe installation work at a high place. Moreover, in Cited Document 3, a configuration is adopted in which the pipe is fixed to a die provided in the clamp base. However, during piping work, it is necessary to process high-pressure pipes and low-pressure pipes of different sizes. For this reason, in the configuration in which the dies are provided in the clamp base as in the cited document 3, it is necessary to replace the dies having different sizes, so that it is difficult to efficiently flare the pipes having different sizes.

  On the other hand, in the electric flare tool described in the cited document 4, a machining system housing with a built-in screw body and a main shaft and a drive system housing with a built-in motor and torque clutch are provided separately, and the end of the pipe is formed in the machining system. A configuration in which the drive system housing is connected after being fixed to the housing is shown. However, in order to machine a pipe at a high place with this configuration, after fixing the machining system housing to the end of the pipe, the work system housing is taken out and connected to the machining system housing while maintaining this state. . Then, the operator operates the drive system housing with the other hand while holding the processing system housing attached to the high place pipe with one hand. Further, the means for fixing the machining system housing to the pipe end part is to insert the pipe end part into an insertion hole formed at one end of the machining system housing and fix it with a toggle lever. However, two dies corresponding to the diameter of the pipe are inserted into the insertion hole of the processing system housing, and it is necessary to accurately insert the end of the pipe in accordance with the hole of the die. Since each of these housings is heavy, there is a disadvantage that work at a high place becomes a dangerous work. Moreover, since the cited document 4 does not disclose means for extracting the processed pipe from the hole of the die, it cannot be actually used.

  The present invention is intended to solve the problems of such a conventional configuration, and is improved in volume reduction and weight reduction, safety of work in unstable high places, and ease of operation. The purpose is to provide an electric flare processing machine.

To achieve the above object, a first aspect of the present invention, the clamping device 6 provided integrally with flaring machine F, grip 6c of the clamping device 6, clamping portion 6a for opening and closing the operation of 6d , an electric flared equipped with a female clip 2 to be fixed to 6b, flaring machine F has a slider 15 that reciprocates while rotating by the rotation of the motor 12, the leading end of the slider 15 The eccentric cone 19 is attached to the pipe P, and the rotating eccentric cone 19 is pressed into the opening of the pipe P end fixed to the clamp device 6 so as to flare the pipe P end.

As a result, it can be performed easily and safely even in high places such as air conditioning piping work.

Moreover, the female clips 2 are provided according to the size of the diameter of the pipes P, and the female clips 2 fixed to the ends of the pipes P are sequentially clamped in the clamping parts 6a and 6b of the clamping device 6. Since it is provided so as to be fixed and flared, it can be carried out very easily even in pipe construction in which the high-pressure pipe and the low-pressure pipe have different pipe diameters , such as air-conditioner piping work.

Since the flaring machine F to which the core cone 19 is attached is formed, and the clamp device 6 for fixing the end of the pipe P in the advancing direction of the eccentric cone 19 is provided integrally with the flaring machine F, the worm gear The length from 13 to the eccentric cone 19 is extremely short. As a result, the clamping device 6 and the flare processing machine F are rationally integrated, and the reduction and weight reduction of the volume of the electric flare processing machine main body are realized. Therefore, since the clamping device 6 of the present invention can be operated with only one hand, the device of the present invention can be inserted even in a narrow space. Therefore, ceiling hanging work for outdoor construction, wall hanging work, roofing work, etc. Work in unstable places on high places and ladders can be performed safely, and pipes can be easily machined in ceilings and indoor units, or in places that have been difficult until now.

  As described above, according to the present invention, it is possible to reduce the volume and weight of the main body of the electric flare processing machine and to improve the safety of operation at an unstable high place and the ease of operation. It is what you play.

  The best mode of the present invention is to provide a slider 15 which can be moved forward and backward via a worm gear 13 provided on the drive shaft of the motor 12 and a wheel gear 14 which transmits the rotation of the worm gear 13 at a right angle. A flare processing machine F having an eccentric cone 19 attached to the tip is formed. On the other hand, a clamp device 6 for fixing the end portion of the pipe P in the advancing direction of the eccentric cone 19 is provided. The electric motor which flare-processes to the pipe P end part by providing this clamp apparatus 6 and the flare processing machine F integrally, and pressing the rotating eccentric cone 19 to the opening part of the pipe P end part fixed to this clamp apparatus 6 Configure flare processing machine. The female clip 2 is clamped and fixed to the side surface of the end of the pipe P, and the fixed female clip 2 is slid into the opening of the clamp device 6, and the female clip 2 and the end of the pipe P are inserted into the clamp device 6. To fix. This clamping device 6 has clamping parts 6a and 6b, gripping parts 6c and 6d, and a lock mechanism that locks the fixed state of the clamping parts 6a and 6b. Then, the substantially block-shaped female clip 2 fixed around the end of the pipe P is fitted and inserted into the opened sandwiching portions 6a and 6b. Furthermore, the original purpose is achieved by providing the pipe P together with the female clip 2 between the clamping parts 6a and 6b to be crimped by the operation of the grip parts 6c and 6d.

  The basic configuration of the flare processing machine of the present invention includes a flare processing machine F, a clamp device 6 provided integrally with the flare processing machine F, and a female clip 2 that is clamped and fixed to an end side surface of the pipe P ( 1 and 6).

  The flare processing machine F is provided with a slider 15 that can be moved forward and backward via a worm gear 13 provided on the drive shaft of the motor 12 and a wheel gear 14 that transmits the rotation of the worm gear 13 at a right angle. An eccentric cone 19 is attached (see FIGS. 11 and 12). The worm gear 13, the wheel gear 14, and the slider 15 of the flaring machine F are housed inside the gear case 5 (see FIGS. 10 and 13). Further, the flare processing machine F is provided with a substantially box-shaped fixed jaw 4 on the advancing side of the eccentric cone 19, and fixes one of clamping portions 6 a and 6 b of a clamp device 6 to be described later. (See FIGS. 1 and 10). Each gear is housed in a gear case 5, and a fixed jaw 4 is provided on the gear case 5.

  11 to 13 show cross-sectional views inside the gear case 5. In this figure, when the start switch S1 is pushed, the motor 12 rotates and the worm gear 13 decelerates to transmit the rotation in a right angle direction and turn the wheel gear 14 (see FIG. 11). The rotation is transmitted to the slider 15 by means of a concave and convex rotary connecting portion 16 in the wheel gear 14 (see FIG. 13). A female screw 17 is provided inside the slider 15, and the slider 15 reciprocates in the B direction while rotating in the gear case 5 by the action of the male screw 18 fixed to the gear case 5 in the slider 15. The eccentric cone 19 moves forward while being eccentric (see FIG. 12). After the flare processing by the eccentric cone 19, when the load current of the motor reaches the current set by the flare processing adjustment volume 23, the automatic control circuit 11 sends an extremely different current to invert the motor 12, and the eccentric cone 19 is restored to the original. It returns to the position and automatically stops and the power is turned off. FIG. 14 shows a battery box 21 that houses the battery 24. The illustrated battery box 21 is connected to an extension cord 20 and includes a belt holder 22 and a flare processing adjustment volume 23. In addition, as shown in FIG. 18, the battery 24 can be an integrated battery 25 that is detachable from the flare processing machine F.

  The automatic control circuit will be described with reference to FIG. The circuit configuration is a circuit using a relay and a thyristor. When the start switch S1 is pressed, a SCR1 toggling signal that moves the power supply relay L1 and a coil of 12V are simultaneously applied to the coil of the power supply relay L1 from D1. As a result, the SCR1 is turned on and the power supply relay L1 becomes an A contact. At the same time, the power supply relay L1 is self-held by the current from D6, and the power is turned on to this circuit. Self-holding is to turn off the power when the power supply relay L1 is cut when the battery voltage drops. Then, the 12V current from the power supply relay L1 passes through R1 to the tens of the retraction relay L2, and from the contact B of the retraction relay L2, 12V flows to the motor 12 and the motor 12 rotates counterclockwise. .

  When the flaring process is completed and the load current increases, a potential difference is generated at both ends of R1, and when a signal is input to the base of Tr1 due to the voltage, the signal current flows from the collector through R2 to D3 and D4 and becomes the trigger signal of SCR2. The SCR 2 is turned on, and a current flows through the coil of the retraction relay L 2, and the retraction relay L 2 becomes an A contact, and a current opposite to 10 and − flows through the circle 1 and the motor 12. As a result, the motor 12 rotates counterclockwise and the slider 15 returns to its original position. Further, ten currents from circle 1 from retraction relay L2 pass through R3 and R4 and are charged to C1 and C2 for turning off SCR1. When the slider returns to the end, the load current increases in the motor 12, a potential difference occurs between both ends of R1, a signal enters the Tr1 base, and when SCR3 is turned on, the turn-off current charged in C2 flows to SCR1, SCR1 turns off and the power supply The relay L1 is turned off.

  To forcibly return the slider to its original position during flare processing, pressing the forced retraction switch S2 turns on the power supply relay L1 from D2, and a signal enters the gate of SCR2 from D5 to activate the retraction relay L2. A current opposite to -10,-is supplied to the motor 12, and the motor 12 reverses and returns to the original position. When the motor 12 returns to the end, the power is turned off. By adopting such an automatic control circuit, it is not necessary to attach a clutch, so that the dimension in the machining axis direction is shortened. In the example, flare processing of a gap of about 8 cm was possible, and the work in the ceiling and the indoor unit could be easily performed. Moreover, the flare processing of the pipe can be completed by pressing the start switch S1 once. Further, the flare processing of the pipes P having different thicknesses can be adjusted by the strength of the flare processing adjustment volume 23, so that uniform flare processing can be performed. The relay of this automatic control circuit can be changed to an FET transistor (see FIG. 16).

  The clamping device 6 is a device that fixes the end of the pipe P in the advance direction of the eccentric cone 19 of the flare processing machine F (see FIG. 5). And the eccentric cone 19 which rotates to the opening part of the pipe P end fixed to the clamp apparatus 6 is pressed, and flare processing is carried out to the pipe P end. This clamping device 6 has clamping parts 6a and 6b, gripping parts 6c and 6d, and a lock mechanism that locks the fixed state of the clamping parts 6a and 6b. Then, a substantially block-shaped female clip 2 described later is fitted and inserted into the opened sandwiching portions 6a and 6b (see FIG. 6). Further, the pipe P is provided so as to be locked together with the female clip 2 between the clamping portions 6a and 6b to be pressure-bonded by the operation of the grip portions 6c and 6d (see FIGS. 7 and 8).

  The clamp device 6 is provided with a magnet 9 for fixing the female clip 2 (see FIG. 5). Then, when the substantially block-shaped female clip 2 fixed around the end of the pipe P is fitted and inserted into the sandwiched portions 6a and 6b that are opened, the female clip 2 is aligned with the position where the female clip 2 is flared. It is made to magnetize in the clamping parts 6a and 6b (refer FIG. 7). Further, a sensor switch S3 is provided in the sandwiching portions 6a and 6b to inform that the female clip 2 is in the flare processing position (see FIG. 7). With this sensor switch S3, when the female clip 2 is not in a fixed position, the start is not started even if the start button is pressed. Thus, by providing the magnet 9 and the position sensor switch S3, the female clip can be positioned reliably, a clamping error can be prevented, and even a person unfamiliar with the operation can easily perform it.

  The illustrated clamping device 6 is a pliers-type fixed type, and when the lock release lever 10 is operated, the lock 8 is released and the clamping portions 6a and 6b are opened (see FIG. 6). When the female clip 2 is slid and inserted into the sandwiching portions 6a and 6b, the sandwiching portion 2a is magnetized by the magnet 9 (see FIG. 7). When the grips 6c and 6d are gripped in this state, the lock 8 is activated and the pipe P is clamped and fixed together with the female clip 2. When the unlocking lever 10 is released after the flaring process is completed, the lock 8 is released and the sandwiching portions 6a and 6b are opened. Then, the female clip 2 is removed from the sandwiching portions 6a and 6b, and the operation portion 2b of the female clip 2 is pinched with a finger to open the sandwiching portion 2a, so that the female clip 2 is removed from the pipe P. The illustrated clamping device 6 is provided so that one clamping part 6a is fixed to the fixed jaw part 4 and the other clamping part 6b swings (see FIGS. 10 and 11).

  A female clip 2 is shown in FIGS. The female clip 2 is a clip that is clamped and fixed to the side surface of the end of the pipe P, and the fixed female clip 2 is slid and inserted into the clamped portions 6 a and 6 b of the clamp device 6. And the clamping part 2a of the female clip 2 inserted in the clamp apparatus 6 is clampingly locked by clamping part 6a, 6b with the pipe P end part. The female clip 2 is provided with a substantially block-shaped clamping portion 2a that clamps the side surface of the pipe P having a predetermined diameter by the biasing force of the spring 3a (see FIG. 2). This clamping part 2a functions as a two-piece die (see FIG. 3). Therefore, a taper matching the flare shape is provided on one surface or both surfaces of the sandwiching portion 2a, and the eccentric cone 19 rotates along this taper to flare the pipe P end (see FIG. 4). ).

  The female clip 2 in the illustrated example is provided at one end of the holding portion 2a, and an operation portion 2b for opening and closing the holding portion 2a is provided to be opened and closed via the clip shaft 3 (see FIG. 2). And when the clamping part 2a of the state which clamped the pipe P end part is clamped and locked in clamping part 6a, 6b of the said clamp apparatus 6, the opening edge part of the pipe P of the eccentric cone 19 is carried out. It is provided so that it may be located in the advancing direction (refer FIG. 11). In addition, the female clip 2 is provided according to the size for the large diameter and the small diameter. Each female clip 2 is fixed to the end of each of the large-diameter pipe P and the small-diameter pipe P, and the pipe P is provided to be clamped and fixed to the clamp device 6 together with the female clip 2. . For example, in the piping work of an air conditioner, it is provided so as to be compatible with high pressure piping and low pressure piping. In addition, the female clip 2 corresponding to pipes P of various diameters can be provided and used for other piping work.

  17 to 21 show another embodiment of the present invention. In this embodiment, one of the grip portions 6c and 6d of the clamp device 6 is formed in a cylindrical shape, and a grip tube 6e that houses the motor 12 is provided (see FIG. 17). Further, a grip portion 6d is provided so as to be openable and closable with respect to the grip cylinder 6e. The locking mechanism of the clamping device 6 is provided so as to operate when the grip portion 6c is closed and to be released when the grip portion 6c is opened.

  A battery 25 is detachably attached to the lower end portion of the grip cylinder 6e (see FIGS. 18 and 19). As a result, the gear case 5, the gripping cylinder 6e, and the battery 25 are arranged substantially in a straight line (see FIG. 20). As a result, the thickness of the portion where the pipe P is processed is sufficient for the slider 15 to retract (see FIG. 21), and the workability in a narrow place is further improved. In addition, the battery 25 has a high versatility by using a commercially available battery as an adapter type battery.

  The female clip 2 shown in FIG. 18 to FIG. 20 is obtained by screwing a spectacle clip as the operation portion 2b to the clamping portion 2a. According to such a female clip 2, the processing of the female clip 2 is facilitated, and a lighter female clip 2 can be obtained.

  In order to use the flare apparatus of the present invention, first, the female clip 2 matching the diameter of the pipe P is clamped and fixed to the side surface of the end of the pipe P to be processed. Next, the holding portion 2a of the female clip 2 in a fixed state is slid into the holding portions 6a and 6b of the clamp device 6, and the lock 8 is activated when the grip portions 6c and 6d of the clamp device 6 are gripped in this state. The pipe P is clamped and fixed together with the holding portion 2 a of the female clip 2. When the start switch S1 is pressed, the eccentric cone 19 provided at the tip of the slider 15 moves forward while being eccentric, and the opening end of the pipe P is flared. When the flare processing is completed, the eccentric cone 19 is automatically retracted together with the slider 15, and the power is turned off. Thereafter, when the lock release lever 10 is operated, the lock 8 is released and the sandwiching portions 6a and 6b are opened. Then, the female clip 2 is removed from the sandwiching portions 6a and 6b, and the operation portion 2b of the female clip 2 is pinched with a finger to open the sandwiching portion 2a, thereby removing the female clip 2 from the pipe P.
