Abstract
Description
Technical Field
[0001] The utility model relates to a fastening device, in particular to a cutting wire fastening device for wire cutting. Background Art
[0002] Cutting wire refers to the wire used to cut objects. There are many kinds of materials for cutting wire. Different materials can be selected according to different functions and requirements. Molybdenum wire is a kind of cutting wire. It mainly refers to a consumable made of precious metals such as molybdenum that moves continuously with a high-voltage electric field to cut the workpiece during wire cutting. That is, the thin metal wire that moves continuously when the wire cutting machine tool processes the workpiece is called the electrode wire, which can perform pulse spark discharge etching on the workpiece and cut the metal into shape.
[0003] The wire feeding steps of existing cutting machines are generally manual operations. The operating steps are as follows: first fix one end of the molybdenum wire on the wire drum, hold the molybdenum wire disk and rotate the wire drum counterclockwise to let the molybdenum wire wind a few turns first, then adjust the wire feeding speed to slow, hold the molybdenum wire and get into position, turn on the wire feeding start switch to start wire feeding, and control the molybdenum wire with your left hand when feeding the wire, so that the molybdenum wire is evenly arranged on the wire drum. When the wire drum moves to the right and you feel that the molybdenum wire has been fed enough, stop feeding the wire, and then thread the molybdenum wire according to the introduction route, fix the other end of the molybdenum wire on the wire drum, then loosen the left and adjust the right stroke switch, hold the molybdenum wire with the wire tightening hand wheel, and adjust it appropriately. The wire is pulled back evenly with constant force, and the wire feeding is finally started. The wire drum moves to the left and the molybdenum wire stops when it is almost finished. The molybdenum wire is loosened and re-fixed to complete the wire tightening. However, there are still some shortcomings in actual use. For example, during the wire cutting of the workpiece by the molybdenum wire, the molybdenum wire will often relax due to high-speed movement, which will cause the constant tension of the molybdenum wire to deteriorate. The deterioration of the constant tension will affect the machining accuracy of the workpiece. In order to ensure the machining accuracy of the workpiece, the molybdenum wire needs to be manually tightened again every time the molybdenum wire is relaxed. The wire tightening steps are repetitive and cumbersome, which takes a long time and easily reduces the wire cutting efficiency of the workpiece.
[0004] Therefore, there is a particular need for a cutting wire fastening device for wire cutting to solve the problems existing in the prior art. Utility Model Content

[0020] The embodiments of the present invention will be described below with reference to the accompanying drawings.
[0021] Embodiment: A cutting wire fastening device for wire cutting, see Figure 1-Figure 5 As shown, it includes a support frame 1, a shell 2, a connecting block 3, a motor 4, a winding wheel 5, a screw 13, a pulley 7, a molybdenum wire 6 and a controller 12. The left side of the support frame 1 is connected to the first shell 2 by bolts, and the top of the connecting block 3 is connected to the second shell 2 by bolts. At least three mounting holes are provided on the support frame 1 and the connecting block 3. The right side of the support frame 1 is connected to the motor 4 by bolts. The right side of the support frame 1 is rotatably connected to the winding wheel 5, and the output shaft of the motor 4 is connected to the winding wheel 5. The winding wheel 5 is threaded with two staggered screws 13, and the disc of the screw 13 is provided with a rubber gasket for increasing pressure. At least two pulleys 7 are rotatably connected to the support frame 1, and at least one pulley 7 is rotatably connected inside the shell 2. The winding wheel 5 is wound with a molybdenum wire 6, and the molybdenum wire 6 is wound between all the pulleys 7. A controller 12 is connected to the right side of the support frame 1 by bolts. The controller 12 is electrically connected to the motor 4, and the motor 4 is operated to rotate the winding wheel 5 to release and reel in the molybdenum wire 6. It also includes a screw 9, a knob 8, a tension wheel 11 and a guide rod 10. The support frame 1 is rotatably connected to the screw 9. The right end of the screw 9 is connected to the knob 8 for auxiliary rotation by welding. The outer thread of the screw 9 is connected to the tension wheel 11. The molybdenum wire 6 is wound around the tension wheel 11. All the pulleys 7 and the tension wheel 11 are on the same vertical plane. The support frame 1 is connected to the guide rod 10 by welding. The tension wheel 11 is slidably connected to the guide rod 10. The guide rod 10 is the same length as the screw 9, so that the guide rod 10 can fully guide the tension wheel 11. By rotating and reversing the screw 9, the tension wheel 11 moves left and right.
[0022] First, the staff installs the device at a suitable position on the cutting machine. After the installation is completed, turn the front screw 13 upwards to place one end of the molybdenum wire 6 between the surface of the winding wheel 5 and the front screw 13, and then turn the front screw 13 downwards to fix one end of the molybdenum wire 6 on the front side of the winding wheel 5. Then, turn on the motor 4 through the controller 12 to control the speed of the output shaft of the motor 4. The output shaft of the motor 4 rotates to drive the winding wheel 5 to rotate and start winding the molybdenum wire 6. When winding, the molybdenum wire 6 is gradually wound on the winding wheel 5 from left to right. When a proper amount of molybdenum wire 6 is wound on the winding wheel 5, turn off the motor 4, cut the molybdenum wire 6, and wind the molybdenum wire 6 around all the pulleys 7 and the tension wheel 11, repeat the above steps after winding, fix the other end of the molybdenum wire 6 to the rear side of the winding wheel 5, when the workpiece needs to be cut by wire, restart the motor 4 to make the winding wheel 5 start to rotate, and when the winding wheel 5 rotates, the molybdenum wire 6 is released while the molybdenum wire 6 is wound up, so that the molybdenum wire 6 runs at high speed along the pulley 7 and the tensioning wheel 11 to cut the workpiece. When the molybdenum wire 6 becomes loose, temporarily turn off the motor 4 to stop the wire cutting operation of the workpiece, and then pinch the knob 8 with your hand to turn the screw 9, so that the tensioning wheel 11 moves to the left to apply tension to the molybdenum wire 6, so as to achieve the purpose of fast wire tightening and avoid time-consuming wire tightening, which reduces the wire cutting efficiency of the workpiece.
