Tungsten wire can also be used to make thermocouples for measuring temperature at high temperatures. Therefore, tungsten wire is an important component in electronic devices.
[0003] Since the required length of tungsten wire is not very long when in use, it is necessary to cut the tungsten wire and cut it into pieces so that its length meets the use requirements.

[0027] Example
[0028] Reference Figure 1-Figure 5The utility model provides a technical solution: a tungsten wire cutting limit device, including a base 1 and a limit mechanism 3, a cutting machine 2 is installed on the base 1, the limit mechanism 3 includes a limit wheel 31, a support seat 311 is installed on the base 1, a hollow bin 312 is installed on the top of the support seat 311, the inner part of the hollow bin 312 is installed with the limit wheel 31, the inner part of the hollow bin 312 is slidably connected to a connecting rod 321, a pressure wheel 32 is installed at one end of the connecting rod 321, a limit column 33 is installed on the top of the hollow bin 312, and the limit column 33 is used to limit the connecting rod 321.
[0029] In a preferred embodiment, the upper surface of the hollow bin 312 is fixedly connected to the limit frame 4, the connecting rod 321 passes through the interior of the limit frame 4 and is rotatably connected to the interior of the connecting rod 321, and the limit column 33 also passes through the interior of the limit frame 4. In order to facilitate the adjustment of the position of the pressure wheel 32, the device makes the connecting rod 321 pass through the interior of the limit frame 4. At the same time, in order to ensure that the limit column 33 can be used stably, the limit column 33 also passes through the interior of the limit frame 4. The connecting rod 321 and the limit column 33 can be limited by the limit frame 4 to ensure stable use.
[0030] In a preferred embodiment, two limit columns 33 are provided and are respectively fixedly installed on the top of the hollow bin 312. The outer surface of the limit column 33 is fixedly connected to the limit layer plate 5, and the outer surface of the connecting rod 321 is fixedly connected to the receiving plate 6. The device adjusts the position of the pressure wheel 32 by rotating the connecting rod 321 and then lifting or lowering the connecting rod 321. After the position of the pressure wheel 32 is adjusted, the connecting rod 321 can be rotated to move the receiving plate 6 on the connecting rod 321 to the limit layer plate 5 on the limit column 33. The receiving plate 6 is supported by the limit layer plate 5, so that the pressure wheel 32 can be used stably.
[0031] In a preferred embodiment, the surface of the base 1 is fixedly connected to the vertical plate 7, and a cylinder 8 is fixedly installed on one side of the vertical plate 7. The cylinder 8 is used to place the tungsten wire winding roller for convenient wire unwinding. After the tungsten wire is produced, it will be wound on the roller. The device cuts the tungsten wire, so it is necessary to unwind the tungsten wire. To facilitate unwinding, a vertical plate 7 is installed on the base 1, and a cylinder 8 is installed on the vertical plate 7. When unwinding, the tungsten wire roller is sleeved on the cylinder 8, and the tungsten wire can be driven to rotate by pulling the tungsten wire, so as to facilitate unwinding and process the tungsten wire. A processing table 9 is fixedly installed on the upper surface of the base 1, and a cutting machine 2 is installed above the processing table 9. The upper surface of the processing table 9 is fixedly connected to a mounting frame 10, and a cutting machine 2 that can move up and down is installed on the inner side of the mounting frame 10. The tungsten wire is moved to the processing table 9, and the cut portion of the tungsten wire is facing the cutting machine 2. At this time, the cutting machine 2 can be controlled to move downward, and the tungsten wire is cut by the cutting machine 2, so as to meet the use requirements.
[0032] To ensure that the device can be used stably, a hollow bin 312 is fixedly installed on the top of the support seat 311, and a limiting wheel 31 is rotatably installed inside the hollow bin 312. The positions of the limiting wheel 31 and the pressure wheel 32 correspond to each other, and the pressure wheel 32 is rotatably installed at the bottom end of the connecting rod 321. Each component that can be used stably is connected in a fixed manner so that it can be used stably. At the same time, a limiting wheel 31 is rotatably installed inside the hollow bin 312. The limiting wheel 31 cooperates with the pressure wheel 32 to limit the conveying of the tungsten wire, thereby avoiding the deviation of the tungsten wire during the conveying process and meeting the requirements of use.
[0033] By unwinding the tungsten wire roller, passing through the interior of the hollow bin 312, and moving to the position of the processing table 9, during this process, not only the tungsten wire needs to be limited, but also the tension of the tungsten wire needs to be maintained, which can improve the stable conveying effect of the tungsten wire and avoid deviation. Therefore, a tension adjustment mechanism 11 is installed on the limit frame 4. The tension adjustment mechanism 11 includes a connecting rod 111, a rotating roller 112 and a plug-in rod 113. The connecting rod 111 is rotatably installed on the outer side of the limit frame 4, and one end of the connecting rod 111 is rotatably connected to the rotating roller 112. The outer surface of the limit frame 4 is fixedly connected to the arc plate 12, and the plug-in rod 113 is plugged into the interior of the arc plate 12. The outer surface of the arc plate 12 is provided with a plug-in hole 13, and the outer surface of the connecting rod 111 is provided with a positioning hole 14. The plug-in rod 113 passes through the interior of the plug-in hole 13 and is plugged into the interior of the positioning hole 14.
[0034] During the transportation of the tungsten wire, the tension of the tungsten wire is prone to weaken. At this time, the tungsten wire is prone to shift during the transportation process, which makes it impossible for the tungsten wire to move to the position of the processing table 9, affecting the processing of the tungsten wire. Therefore, when the tension of the tungsten wire is reduced, it is necessary to rotate the connecting rod 111 upward to raise the height of the tungsten wire, which can increase the tension of the tungsten wire so that the tungsten wire can be stably transported and meet the requirements of use.
[0035] Specifically, the working process or working principle of a tungsten wire cutting limit device is as follows: since the required length of the tungsten wire does not need to be very long when in use, the tungsten wire needs to be cut and cut off during use, and its length meets the use requirements. The current method of cutting tungsten wire is to transport the tungsten wire to the position of the cutting equipment, and then control the cutting equipment to cut it to obtain tungsten wire that meets the use requirements.
[0036] Although the above-mentioned cutting method can realize the cutting of tungsten wire, since the tungsten wire is relatively thin, it is easy to deviate during the transportation of the tungsten wire, which makes it impossible for the tungsten wire to be accurately moved to the bottom of the cutting device. Either the tungsten wire cannot be cut off, or the tungsten wire has left the cutting position, which will affect the processing effect of the tungsten wire. Therefore, this device is designed to solve this problem.
[0037] When using the device to cut the tungsten wire, first connect the external power supply, place the tungsten wire roller on the cylinder 8, which can facilitate wire release, move the tungsten wire into the hollow bin 312, and transport it through the limiting wheel 31, and pull it out from the hollow bin 312. In actual use, according to the different diameters of the tungsten wire, it is necessary to adjust the position of the pressure wheel 32. By rotating the connecting rod 321 and rotating the receiving plate 6 away from the limiting layer plate 5, the connecting rod 321 can be raised and lowered to adjust the position of the pressure wheel 32. Through the cooperation of the pressure wheel 32 and the limiting wheel 31, the tungsten wire can be limited to ensure stable transportation.
[0038] After adjusting the position of the pressure wheel 32, the connecting rod 321 can be reversed again to move the receiving plate 6 to the limiting layer plate 5, thereby limiting the connecting rod 321 and making it stable for use. At this time, the pressure wheel 32 can be used normally, and during use, the tungsten wire is passed through the rotating roller 112 at one end of the connecting rod 111. The connecting rod 111 is provided with two and is respectively provided on the left and right sides of the limiting frame 4. The tungsten wire will also pass through the two rotating rollers 112. The tungsten wire is provided on the upper surface of the rotating roller 112, and then the tungsten wire is moved to the position of the processing table 9. The device is provided with a winding mechanism on the processing table 9. When the length of the tungsten wire winding reaches the required length, the cutting machine 2 can be controlled to cut the tungsten wire so as to obtain tungsten wire that meets the requirements for use.
[0039] The device can limit the position of the tungsten wire by passing the tungsten wire through the hollow bin 312, so that the tungsten wire can be accurately moved on the processing table 9 and correspond to the position of the cutting machine 2 to prevent deviation, so that the cutting machine 2 can cut the tungsten wire.
[0040] If the tension of the tungsten wire is insufficient during the conveying process, the connecting rod 111 can be controlled to rotate to lift the rotating roller 112. Lifting the rotating roller 112 upward can straighten the tungsten wire. After adjusting the position of the connecting rod 111, the connecting rod 113 is inserted into the inside of the connecting hole 13 and the inside of the positioning hole 14, so that the connecting rod 111 can be positioned, so that the tungsten wire can move with sufficient tension, effectively avoiding the deviation of the tungsten wire during the movement process, which affects the processing of the tungsten wire.
[0041] It should be noted that the cutter 2 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
