[0025] The utility model is described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 to Figure 2 As shown, the utility model is an automatic adjustment device for wire-cut molybdenum wire, comprising a frame 1, a barrel 2 rotatably arranged on the frame 1, a guide wheel group 3 used in conjunction with the barrel 2, and an adjustment component 4 arranged on the frame 1, wherein the guide wheel group 3 is provided with a sensor 31, and a molybdenum wire 5 is wound on the outside of the barrel 2 so that the molybdenum wire 5 passes through the guide wheel group 3 and abuts against the adjustment component 4, and the adjustment component 4 is used to adjust the tension of the molybdenum wire 5.

[0027] During operation, a driving motor (not shown) is arranged on the outside of the frame 1, and the driving motor drives the barrel 2 to rotate relative to the frame 1, so that the molybdenum wire 5 can be pulled out of the barrel 2, and the molybdenum wire 5 passes through the guide wheel group 3 and abuts against the adjustment component 4. Since the guide wheel group 3 is provided with a sensor 31, the sensor 31 can be a pressure sensor 31. The sensor 31 detects the tension change of the molybdenum wire 5 in real time and measures the actual tension value, and sends the measured data to the control system. After the control system analyzes and processes the data, the adjustment amount is fed back to the adjustment component 4. The adjustment component 4 adjusts and acts on the molybdenum wire 5 in real time, effectively adjusting the tension of the molybdenum wire 5, thereby avoiding problems such as shaking wire, overlapping wire, and broken wire, making the molybdenum wire 5 move more smoothly, extending the service life of the molybdenum wire 5, and improving the processing accuracy. It is also unnecessary to manually perform the wire tightening adjustment work every day, thereby reducing the labor intensity and labor cost. The utility model realizes automatic adjustment of the tension of the molybdenum wire 5, ensures that the molybdenum wire 5 has a constant tension, has good cutting performance, and improves the processing efficiency and processing quality.

[0028] The adjustment assembly 4 of this embodiment includes a bracket 41, a screw 42 arranged on the bracket 41, a nut 43 threadedly connected to the screw 42, a movable seat 44 arranged on the nut 43, a tensioning wheel 45 rotatably connected to the movable seat 44, and a force-applying assembly 46 arranged at one end of the screw 42, the tensioning wheel 45 rolling against the molybdenum wire 5, guide rods 47 are arranged on both sides of the screw 42, guide sleeves 48 are arranged on both sides of the movable seat 44, and the guide sleeves 48 are slidably connected to the guide rods 47. Specifically, the bracket 41 is installed and fixed on the frame 1, and the screw 42 is driven to rotate by the force-applying component 46. The rotating screw 42 drives the nut 43 to move, and the moving nut 43 drives the moving seat 44 to move up and down along the bracket 41. The moving seat 44 is slidably connected to the guide rod 47 through the guide sleeve 48, and the guiding effect is good, so that the moving seat 44 can be lifted up and down smoothly. The tensioning wheel 45 rolls on the molybdenum wire 5, so as to adjust the tensioning force of the molybdenum wire 5, and the adjustment effect is good. The structural self-locking characteristics of the screw 42 and the nut 43 are used to solve the problems of the unstable tensioning force of the molybdenum wire 5 of the wire cutting machine, the occurrence of wire shaking, wire overlap, wire breakage, etc., thereby extending the service life of the molybdenum wire 5 and improving the cutting accuracy of the molybdenum wire 5.

Specifically, the weight 466 is wrapped around the outer periphery of the transmission wheel 464 through the pull rope 465. When the weight 466 is lowered, the weight 466 performs free fall motion under the action of its own gravity, thereby driving the transmission wheel 464 to rotate. The rotating transmission wheel 464 drives the worm 462 to rotate. The rotating worm 462 engages with the worm wheel 463 for transmission, thereby realizing that the worm wheel 463 drives the screw 42 to rotate. Since there is a multi-tooth meshing transmission between the worm 462 and the worm wheel 463, the transmission is slow and smooth, the noise is small, and it also has a self-locking structure and high transmission stability.
