Description of the Invention: [Technical Field of the Invention] The present invention relates to a manually operated, portable, hydraulically driven expansion hand tool. [Prior Art] Conventional connectors, adapters or connectors have been used to attach malleable cylindrical conduits to pipes, rubber hoses, connectors or other conduits. One of the joining methods involves flaring the pipe. There are many ways to flank the tubing, which involves plastically deforming the end or end regions of the tubing. A conventional flaring device is disclosed in U.S. Patent No. 4,068,515, the entire disclosure of which is incorporated herein by reference to the entire disclosure of the entire disclosure of the entire disclosure of On October 25th, the pipe with the flared end is exemplified 'where the flared cone is pushed to the end of the pipe. Generally, these and similar patents relate to an apparatus for forming flaring of different shapes and forming at the end of a hollow malleable cylindrical conduit. The contour of the shape of the flared end is exactly the same as the support surface of the connector to which the flared pipe is to be joined. In many other applications, such as attaching a conduit to another conduit of the same diameter, it is desirable that one end of the tubing has a radially outward expansion. Such connections will seal the fluid within the tubing when welding or brazing. Therefore, it is necessary to provide a portable hand tool that enables a controlled expansion at the end of the tube. 201238674 SUMMARY OF THE INVENTION The movement of a dilator driven by a manual hydraulic pump in a hydraulically driven flared hand tool can expand the die assembly to move the die assembly radially outwardly to the hollow forgeable cylindrical tubing Make a flaring. The tool has a manual hydraulic pump that is integral with the handle of the tool and thus allows one-handed operation. The manual hydraulic pump produces a linear motion of the shaft. Attached to the shaft is a dilator that moves through the regulator into a die module having a plurality of die elements. The die module is coupled to the regulator. [Embodiment] A more complete understanding of the present invention can be obtained from the description and accompanying drawings. There is a need for a versatile hand tool that can be used as a repair tool for tubing (catheters) to enable tubing to be attached to or as part of a larger machine or system. The present invention is a portable hand tool for creating an expansion (flare) at the end of a pipe. The tool can be used as a service device for connecting a fluid line to a different conduit. The present invention is a manually operated hand tool that provides a special radially outward flare over the deformable tubing. The present invention includes an internally threaded adjuster that is axially moveable on a threaded locating bolt that is secured to a manual hydraulic pump by threads and a set screw. The rotation of the adjuster relative to the pump body brings the two components axially close to each other or away from each other. The adjuster is coupled to the die portion &' to move the die portion along the adjuster. The pump section consists of a cylinder block, a flared piston, a threaded positioning 201238674 bolt and a pump component. The cylinder has a pressure cylinder located at the front of the cylinder. The cylinder has a hydraulic reservoir and a reservoir cover that connects the opposite ends of the cylinder. The locating bolt is a long barrel having a thread on its outer surface and rigidly connected to the cylinder. The reamer piston is located in the cylinder and has an axially elongated body extending through the locating bolt. The pump component includes a lever arm, a 'one spring' and a piston that forces liquid from the reservoir to the pressure front chamber of the cylinder. The pump component also has a seal that allows fluid to flow back to the reservoir to activate its initial position. The flared piston has an open face, the expansion is in the open face, and the expander moves in and out relative to the piston. In a first embodiment, a dilator of suitable size is flushed into the interior of the tubing, the component being assembled is a "pump", the action guide of the pump entering the expanding die and causing the die insert to move outwardly, The end forms an expanded portion. The knot of the hand tool of the present invention is simple and can be used in any location, including repair of fluid lines, and does not require separation of the tubing from its connection to the field device. The present invention is economically advantageous. Referring now to the drawings, the exemplary embodiment of the invention disclosed in Figure 1a shows an expanded flare hand tool 1 〇 device in accordance with the present invention. This pressure-driven flared hand tool 1 〇 usually has adjusters 1 2 and 21. The hydraulic pump 21 is constituted by a positioning bolt 23, and a cylindrical tube having a thread on the outer surface of the positioning bolt 23. The positioning bolt 23 is fixed to the hydraulic pump main body 40 by a wire nail 25, and it passes through a threaded cylinder to the pressure hollow cylinder. The main body of the pivot storage tank is fully valved when the plug is set back to the device, and the die is expanded to be in the positional position of the pipe structure. Therefore, the liquid hydraulic pump of the embodiment is fixed at the fixed screw 24 axial direction 201238674 . The flared piston 22 is a solid cylinder rod having a ring groove 98 at its end and a piston portion 74 at the other end, the piston portion being a larger diameter disk. The piston portion 74 has a Ο-shaped ring 28 and a partial ring 26 that is located in the pressurized cylinder region 75. The spring 27 applies a biasing force to the flared piston 22 which abuts the oil pressure in the pressurized cylinder region 75. The hydraulic pump body 40 also has circular passages 32, 33 and 34 that connect the oil reservoir 54 to the pressurized cylinder region 75 at the front. The pressure of the spring 30 holds the ball 31 in the opening of the ball seat 41 to close the opening. The spring seat 29 sets the contraction of the spring 30. The hydraulic pump 2 1 has a pump linkage system which is constituted by a piston 35 arm 42 and a pivot frame 43. A one-way (check) valve 44 allows hydraulic oil to flow from the reservoir 54 to the passage 34. Oil is pumped from the reservoir 54 through the piston and lever arm 42 into the pressurized cylinder region 75. The piston 35 is fixed in the passage 33 by a cap screw 36, and it is sealed by a 〇-shaped ring 37 and a rear ring. The spring 38 applies an upward pressure to the lever arm 42 through the washer 39. The pressure of the spring 38 keeps the lever arm 42 and the hydraulic pump body 40 open, and the oil flows out through the check valve 44 into the passages 33 and 34 by the piston 35 moving upward. The lever arm 42 is hinged to the pivot frame 43 by a pin 47. The pivot frame 43 is rigidly coupled to the hydraulic pump body 40 by the threads 50 and the danger nut 46 on the hydraulic pump body 40, so that the entire pumping system is stabilized. A stop lever 48 coupled to the lever arm 42 limits the separation of the arm 42 from the hydraulic pump body 40. Figure la also shows that the oil reservoir 49 is connected to the back of the hydraulic pump body 40 and is capped by the reservoir cover. The Ο-shaped ring 68 holds the reservoir tank 49 in the hydraulic pump body shape 74. The spring retaining cylinder is attached to the split shaft retaining rod pocket 5 1 40 201238674 which presses only 3 5 nails 45. In order to increase and discharge the oil in the reservoir 54, a plug reservoir cap 51 is provided which is connected to the hydraulic pump body 40 by threads 64. Removal of the tank cover 51 removes the passage of the plug 5 3 . Referring to Fig. la, in the free position of the lever arm 42, the spring 38 applies pressure to the pad and pushes the lever arm 42 away from the hydraulic pump body 4''. The pressure is resisted by the contact of the stop 48 and the pivot frame 43. This is the upper limit of the lever arm 42. Thus, the piston 35 is located at its uppermost position in the oil passage 33, and the oil passages 33 and 34 are filled up in the oil reservoir 54. As the hydraulic oil leaves the reservoir 54, the reservoir bladder 49 contracts, preventing air from entering the system by pressing the lever arm 42 downward toward the hydraulic pump body 40, causing the spring 38 to be passed by the piston 35 through the cylindrical passage 33. Push down to squeeze the oil in channels 33 and 32. The pressure in the passage 32 pushes the spherical ball 31 away from the opening of 41, thus forcing the oil to flow to the pressurized cylinder region 75. Once in the depressed cylinder region 75, the spring 30 applies a biasing force to the ball 31 and closes 32, thus preventing oil from moving from the pressurized cylinder region 75 to the passage 32. Therefore, after several strokes of the lever arm 42, The pressed cylinder region 75 is forced and an axial pressure is applied to the dilator 15 through the flared piston 22 causing the die module 16 to rapidly expand. Referring to Figure lc, reference numeral lb', once the expansion process is completed, the expansion valve is retracted by reducing the pressure in the pressurized cylinder region 75 by the safety valve. When the valve section 62 is rotated counterclockwise, the pressure of the pressurized cylinder region 75 is released. The oil reservoir 54 is connected to the pressurized cylinder region 75 by oil return passages 57, 56 and 55 which are located on a plane perpendicular to the plane in which the oil inlet passages 33 and 34 are located. Pressure relief valve assembly 53 < Set the reservoir 39 lever & This is from the opening of the oil, shrinking, 34, the ball seat plus channel 3 flow. ] Pressure, force, through the material recovery is also 32, by the valve 201238674 door joint 62, valve stem 58, 0 ring 59, ball 67, ball seat 65 and cap screws. The valve stem 58 has a thread 60 in its midsection. The cap screw 61 has an internal pattern 7 8 . The valve stem 58 is screwed into the thread 78 of the cap screw 61. The oil passage guides the valve stem 58 to move axially. The cap screw 61 prevents the valve stem 58 from being unscrewed 56. To close the release valve, the valve section 62 is rotated clockwise so that the valve stem 58 is brought down into the passage 56. The fully closed valve position is shown in Figure lb, where the flat end 77 of the valve stem 58 presses the ball 67 against the ball seat 65 to block the passage 56. In this position, oil can only flow from the reservoir 54 through the single passages 3 4, 3 3 and 3 2 to the pressurized cylinder region 75. To open the release door, the valve section 62 is rotated counterclockwise to bring the valve stem 58 upwardly away from the opening of the passage. The position at which the valve is opened is shown in Figure lc, and the flat end 77 is separated from the ball 67 so that the passages 5 7, 5 6 and 5 5 are connected. In the open position, the oil pressure in the pressurized cylinder region 75 causes the oil to be released by returning through the passages 57, 56 and 55 back into the tank 54 so that the spring 27 retracts the flared piston 22 from the module 16 The expander 15 is opened to radially contract the punch module 16. As shown in Fig. 1a, the adjuster 12 has an internally threaded portion 66 which engages with the positioning bolt 23. The dilator module 16 is a critical component in the flare process because its diameter varies depending on the size of the tubing. The regulator 1 2 has a cylindrical hole in which the dilator 15 moves. The rear end of the punch module 16 is screwed onto the adjuster 12. For pump operation, the oil lever arm 42 is pressed downward toward the pump body 4, and is repeatedly released. The oil lever arm 42 hydraulically drives the flare piston 22 and deforms the position where the pipe is expanded outward. In order to restore the deformed tubing, the oil pressure is turned counterclockwise by rotating the valve section 6 2, and the release valve is opened. 6 1 Spiral 56. The middle > is flushed into the pocket of the valve 56 and is released by the 201238674. The mode element is a combination of the volume element and the pressure-expanded expansion. Fig. 2b, which shows the details of the die module 16 and the dilator. The die module 16 includes a die holder 102 having a thread and a plurality of punching members 1 〇4. In one embodiment, the plurality of die elements are comprised of six die members 104. Although other numbers of die elements can be used, both can cause the tube to be strained, thus causing the flared end to be fragile, tearing and other failure problems. The die member 1 〇4 is held in the unexpanded position by a spring member 106 or a deformable resilient material. When the die assembly is in the unexpanded position, as shown in Figure 2a, the die 104 slides into the interior of the tube 202. One feature of the present invention is that by expanding the flared hand tool 10, there is no need to secure or clamp the tube 202 to clamp or hold the tube 202 to cause damage such as a scratch on the surface, and subsequent sealing of the tube 202, It also caused the weakness of the flared end. When the hydraulic pump body 40 (not shown) is driven, the expander 15 slides inside the module 16. When the dilator 15 is brought into contact with the die member 104, the die member 1 〇4 is moved radially outward. Initially, the movement causes the die assembly 1 to hold the tubing 02 in the proper position. Movement of the dilator 15 then causes the tubing 202 to be flared at a radially outward force applied to the deformable tubing 202 by the die element. The maximum amount of flare is defined by a die holder 102 that limits the outward radial movement of the die assembly 104. When the flare of the deformable tube 202 is completed, as shown in Fig. 2b, the release of the hydraulic pressure generated by the liquid pump body 40 causes the die member 104 to return to its unlatched position, so that the operation and the movement can be completed with one hand. Referring again to Figures 2a and 2b, a detailed cross-sectional view of the die assembly and dilator 201238674 is shown. In another embodiment of the invention, die element 104 has a small recess 1〇8. This notch 108 enables the unexpanded die assembly 1 〇 4 to be inserted into the deformable tube without having to expand the tube 202, the tube 206 having burr-end ends due to cutting, these thorns The ends are capable of producing metal crumbs and lobes that can contaminate the interior regions of the tubing 202. Numerous modifications and alternative embodiments of the invention will be apparent to those skilled in the art The die element and the expander can have a number of different geometric settings. Accordingly, the above description should be understood as being limited to the preferred embodiments of the invention. The structure is substantially changeable without departing from the spirit of the invention, and the exclusive use of all modifications within the scope of the scope of the appended claims is reserved.
