New description: [New technical field] This creation is related to the construction of a wire cutter, especially a wire cutter structure that uses cyclic convection or brush to remove surface debris. [Prior Art] The existing wire cutting technology refers to the application of the linear cutting electric discharge machining composed of the high-precision linear motor drive system and the discharge module of the wire cutting machine. In the process of electrical discharge machining, the machining fluid is used as the medium of discharge, and the workpiece is cut by high precision by the immersion method. It is known that a wire cutting machine uses a fluid tank to store a machining fluid which is penetrated by a lower arm into a groove wall and is capable of processing a metal wire immersed in a machining fluid for processing a workpiece. Due to the immersion of the lower arm into the machining fluid, the working debris generated by the cutting workpiece remains in the machining fluid and adheres to the surface of the lower arm. This fluid groove has an axial displacement movement to the lower arm, and if the surface is attached with working debris, the axial movement is deeply affected. In addition, a sealing member is disposed between the lower arm and the wall of the fluid body, and the working debris may damage the degree of sealing, so that the leakage of the working fluid may be improved. [New content] The main purpose of this creation is to solve the above problems and provide a 5 M324555 wire cutter with improved structure. The seal and the butt joint are connected to form a circulation flow path on the lower arm, and the fluid is injected into the circulation flow path. To clean the working debris attached to the lower arm. A second object of the present invention is to provide a wire cutter structure for the removal of the debris attached to the surface of the lower arm. For the purpose of the foregoing, the present invention is a wire cutter structure improvement, comprising: a body for manipulating the displacement movement of a fluid tank into which a working fluid can be injected, and a metal wire connected to an upper guide and a lower guide at one end of the lower arm Between the lead portions, the metal wire is electrically discharged in the fluid groove; and a circulation flow path is formed by the one seal and the pair of joint members moving and being joined to each other to form a fluid for injecting into the circulating flow path The working debris attached to the surface of the lower arm is circulated and circulated to the outside. The above and other objects and advantages of the present invention will become more apparent from the detailed description and the accompanying drawings. Of course, the creation of the invention may be different on some of the components, or the arrangement of the components, but the selected embodiments are described in detail in the present specification and are not constructed in the drawings. [Embodiment] The linear cutting electric discharge machine implemented by the machining liquid supply system is divided into two types of water jet processing and water immersion processing. This creation mainly improves the structure of the dip 6 M324555 water line cutting brake machine. Fig. 1 shows the construction of one of a plurality of water-immersed wire-cutting machines, which is only for explaining the technical contents of the present creation, but is not limited by such a structure in the patent application. Next, the wire cutting machine of the present embodiment is provided in a body 1 and equipped with a helium control or driving device or a linkage mechanism. Since these constructions are not technical features of the present invention, they will be described first. "Hai body 1 has a base 1 1, the upper device has a table 1 2 which is displaceable along the X-axis or the Y-axis of the drawing, and the table 12 has a fluid groove which can be injected into the machining fluid. 1 3. The fluid groove 13 faces the slot 1 of the body 1 and is provided with a water 丄 5, and the body 穿 penetrates into the fluid groove 3 with the lower arm i 4 along the Y-axis direction of the drawing. The portion of the water retaining member 15 is lowered and the sealing member 2 is used to prevent leakage of the working fluid. The movable body of the body 1 is disposed in the direction of the vertical lower arm i 4 and has a movable rod 6 ′. The movable rod 16 is movably movable along the z-axis direction of the drawing, and has an upper guide portion at an end of the lower extending arm 14 The head i61, and the free end of the lower arm 14 is provided with a lower guiding portion 141, such that the body is located above the fluid groove 13 and a winding portion χ 7 is wound by a metal wire 18 via the upper guide The lead portion i 6 i is pulled to the lower guiding portion to perform the work of discharging and cutting the workpiece to be processed in the fluid in the fluid tank 13 . The creation of this new type focuses on the structural design of the seal 2. In the drawing of the 2 7 M324555 diagram, the sealing member 2 is substantially a square body, and is fixedly positioned on the machine by a plurality of fixing holes 21, and is provided with a stepped shape in the middle position. Hole 2 2, a ring groove 2 3 and a ring group portion 2 4 . The sealing member 2 penetrates the ring groove 23 to the outside through a first injection port 25, a second injection port 26, and a plurality of discharge ports 27. Figures 3 and 4 show the state of implementation of the assembly in the wire cutter. The aforementioned lower arm 14 is provided with a passively displaced engaging member 3 i, and the engaging member 3 cooperates with a clamping plate 3 2 to sandwich the water blocking member 15 and lock. In addition, the mating member 31 is sleeved with a leak-proof ring pad 3 3, and the sealing member 2 is placed on the lower arm 14 via the sleeve hole 2 2 to form the sealing member 2 and the pair in a side-by-side manner. While the fittings 31 are joined together, the leakage ring pad 3 3 can be assembled in the ring group portion 24, so that the sealing member 2 is in the ring groove 23, the leakage ring pad 3 3 and the lower arm. A circulating flow path 28 is formed between 14 and 4. The fluid is injected from the first injection port 25 and the second injection port 26 into the circumscribing flow 208, respectively, and flows cyclically in accordance with the annular wall surface of the ring groove 23 in accordance with the direction of the head of the drawing. Because the injection port 2 5, 26 is injected into the body, the direction of the path of the lower arm 丄 4 is equal to the seven directions of the line, and the tangential t and the radius r of the lower arm 14 are perpendicular to each other. Therefore, the circulation of the flow-in/in inlet creates a strong flushing effect on the circumferential surface, so that the debris attached to the τ-extension arm 14 flows out from the adjacent discharge port 27 to the outside with the fluid. 8 M324555 The seal of the seal 2 has the following advantages for the lower arm 14 of the wire cutter: 1) The debris which is attached to the surface of the lower arm 14 is removed by the rinsing step, and is superior to the system. The cleanup effect of technology.
