Description

Technical Field

[0001] This utility model is a tungsten-molybdenum rod cutting fixture, belonging to the field of tungsten-molybdenum rod processing. Background Technology

[0002] Tungsten-molybdenum rods are alloy materials made from tungsten (W) and molybdenum (Mo), two high-melting-point metals, through electron beam melting or powder metallurgy processes. They typically contain 5%-75% tungsten, with the remainder being molybdenum. Combining the high melting point and hardness of tungsten with the toughness and thermal conductivity of molybdenum, they exhibit excellent creep resistance, high-temperature resistance, and corrosion resistance. Tungsten-molybdenum rod cutting fixtures are specifically designed for processing tungsten-molybdenum rods. They are usually made of high-temperature resistant materials (such as composite metals or ceramics) and are used to precisely clamp the rods, ensuring stability and safety during cutting, forging, or welding processes.

[0003] In existing technologies, some tungsten-molybdenum rod cutting fixtures require the two ends of the tungsten-molybdenum rod to be placed in a fixed support and a sliding support respectively. Then, the adjusting screw is turned, and under the guidance of the guide column, the clamping plate descends along the surface of the adjusting screw until it contacts the surface of the tungsten-molybdenum rod, thus fixing the two ends of the tungsten-molybdenum rod in the fixed support and the sliding support respectively. Since the sliding support can move along the top of the base and the top of the base has a scale line, the cutting length of the tungsten-molybdenum rod can be measured. However, after the tungsten-molybdenum rod is cut, the clamping plate must be moved away from the tungsten-molybdenum rod before the cut tungsten-molybdenum rod can be removed from the fixed support and the sliding support. Then, the remaining tungsten-molybdenum rod is fixed by the clamping plate before cutting can continue. This results in the need to fix the tungsten-molybdenum rod multiple times during the cutting process, thereby reducing the cutting efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a tungsten-molybdenum rod cutting fixture. This fixture solves the problem mentioned in the background art where, after cutting the tungsten-molybdenum rod, the clamping plate must first be moved away from the rod before the cut rod can be removed from the fixed and sliding support seats. Then, the remaining rod must be fixed by the clamping plate before cutting can continue. This results in multiple fixings of the rod during the cutting process, thus reducing cutting efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a tungsten-molybdenum rod cutting fixture, including a base, a moving component is provided at the top of the base, and a measuring component is provided inside the base;

[0006] The movable component includes a connecting frame fixedly connected to the top of the base. A first lead screw is rotatably connected inside the connecting frame, and a first guide rod is fixedly connected inside the connecting frame. A lower limit seat is threadedly connected to the surface of the first lead screw. A second lead screw is rotatably connected to the top of the lower limit seat. A second guide rod is fixedly connected to the top of the lower limit seat. An upper limit seat is threadedly connected to the surface of the second lead screw. A first placement groove is formed on the surfaces of both the lower limit seat and the upper limit seat.

[0007] Furthermore, a support seat is fixedly connected to the top of the base on one side of the connecting frame, and a third placement groove is provided on the surface of the support seat.

[0008] Furthermore, the measuring component includes two storage slots opened in the base, a measuring plate is slidably connected in the storage slots, a connecting plate is fixedly connected to one side of the bearing seat, a plurality of transmission rods are slidably connected in the connecting plate, a locking plate is fixedly connected to the bottom end of the transmission rods, a return spring is sleeved on the surface of the transmission rods, a positioning seat is fixedly connected to one end of the measuring plate, and a second placement slot is opened on the surface of the positioning seat.

[0009] Furthermore, the first placement groove is V-shaped, and an anti-slip pad is fixedly connected to the inner wall of the first placement groove.

[0010] Furthermore, the bottom surface of the support is flush with the bottom surface of the base, and the third placement groove is V-shaped.

[0011] Furthermore, a first turntable is fixedly connected to one end of the first lead screw, and a second turntable is fixedly connected to one end of the second lead screw.

[0012] Furthermore, one side of the measuring plate is serrated, and the locking plate is U-shaped.

[0013] The beneficial effects of this utility model are as follows: The upper limit seat is brought into contact with the surface of the tungsten-molybdenum rod by the second lead screw and the second guide rod, which can limit the tungsten-molybdenum rod. Since the distance between the lower limit seat and the upper limit seat 27 is adjustable, the fixture can be adapted to various types of tungsten-molybdenum rods, thereby expanding the applicability of the fixture. The other end of the tungsten-molybdenum rod is inserted into the second placement groove by the first lead screw, the connecting frame and the first guide rod. At this time, the tungsten-molybdenum rod can be cut to obtain a tungsten-molybdenum rod of a specified length. Since the moving component only fixes one end of the tungsten-molybdenum rod, after the tungsten-molybdenum rod is cut, the cut part is first taken out from the second placement groove, and then the lower limit seat is moved to cut the remaining tungsten-molybdenum rod. The entire cutting process does not require repeated fixing of the tungsten-molybdenum rod, which helps to improve the cutting efficiency.

[0014] Pulling the measuring plate allows it to slide along the storage groove to extend to a suitable length. The cutting length of the tungsten-molybdenum rod can be limited by the positioning seat fixed to one end of the measuring plate. The measuring plate can be limited by the locking plate, transmission rod, connecting plate and return spring. Since the measuring plate slides along the storage groove, the space occupied by the fixture can be reduced, which makes it easier to transport and store the fixture. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a tungsten molybdenum rod cutting fixture, including a base 1, a moving component 2 at the top of the base 1, and a measuring component 3 inside the base 1;

[0023] The movable component 2 includes a connecting frame 21 fixedly connected to the top of the base 1.

[0024] A first lead screw 22 is rotatably connected inside the connecting frame 21, and a first guide rod 23 is fixedly connected inside the connecting frame 21. A lower limit seat 24 is threadedly connected to the surface of the first lead screw 22. A second lead screw 25 is rotatably connected to the top of the lower limit seat 24. A second guide rod 26 is fixedly connected to the top of the lower limit seat 24. An upper limit seat 27 is threadedly connected to the surface of the second lead screw 25. A first placement groove 28 is opened on the surface of both the lower limit seat 24 and the upper limit seat 27.

[0025] The upper limit seat 27 is brought into contact with the surface of the tungsten-molybdenum rod by the second lead screw 25 and the second guide rod 26, thus limiting the tungsten-molybdenum rod. Since the distance between the lower limit seat 24 and the upper limit seat 27 is adjustable, the fixture can be adapted to various types of tungsten-molybdenum rods, thereby expanding the applicability of the fixture. The other end of the tungsten-molybdenum rod is inserted into the second placement groove 38 by the first lead screw 22, the connecting frame 21 and the first guide rod 23. At this time, the tungsten-molybdenum rod can be cut to obtain a tungsten-molybdenum rod of a specified length. Since the moving component 2 only fixes one end of the tungsten-molybdenum rod, after the tungsten-molybdenum rod is cut, the cut part is first taken out from the second placement groove 38, and then the lower limit seat 24 is moved to cut the remaining tungsten-molybdenum rod. The entire cutting process does not require repeated fixing of the tungsten-molybdenum rod, which helps to improve the cutting efficiency.

[0026] Preferably, the first placement groove 28 is V-shaped, and an anti-slip pad 6 is fixedly connected to the inner wall of the first placement groove 28. The V-shape of the first placement groove 28 allows it to fit more closely to the surface of the tungsten-molybdenum rod, and the anti-slip pad 6 increases the friction between the first placement groove 28 and the tungsten-molybdenum rod, thereby improving the limiting effect on the tungsten-molybdenum rod.

[0027] Furthermore, one end of the first lead screw 22 is fixedly connected to the first turntable 7, and one end of the second lead screw 25 is fixedly connected to the second turntable 8. The first turntable 7 facilitates the rotation of the first lead screw 22, and the second turntable 8 facilitates the rotation of the second lead screw 25.

[0028] Furthermore, a support seat 4 is fixedly connected to the top of the base 1 on one side of the connecting frame 21, and a third placement groove 5 is provided on the surface of the support seat 4. The support seat 4 and the third placement groove 5 can provide additional support for the tungsten-molybdenum rod, thereby preventing the tungsten-molybdenum rod from bending during the cutting process.

[0029] Furthermore, the bottom surface of the support 4 is flush with the bottom surface of the base 1, and the third placement groove 5 is V-shaped. This configuration ensures that the tungsten-molybdenum rod remains horizontal after being placed in the third placement groove 5.

[0030] Please see Figure 1 and Figure 3The present invention provides a technical solution: the measuring component 3 includes two storage slots 31 opened in the base 1, a measuring plate 32 is slidably connected in the storage slots 31, a connecting plate 33 is fixedly connected to one side of the bearing seat 4, a plurality of transmission rods 34 are slidably connected in the connecting plate 33, a locking plate 35 is fixedly connected to the bottom end of the transmission rods 34, a return spring 36 is sleeved on the surface of the transmission rods 34, and a positioning seat 37 is fixedly connected to one end of the measuring plate 32, and a second placement slot 38 is opened on the surface of the positioning seat 37.

[0031] Pulling the measuring plate 32 allows it to slide along the storage groove 31 to extend to a suitable length. The cutting length of the tungsten molybdenum rod can be limited by the positioning seat 37 fixed to one end of the measuring plate 32. The measuring plate 32 can be limited by the locking plate 35, the transmission rod 34, the connecting plate 33, and the return spring 36. Since the measuring plate 32 slides along the storage groove 31, the space occupied by the fixture can be reduced, which facilitates the transportation and storage of the fixture.

[0032] Preferably, one side of the measuring plate 32 is serrated, and the locking plate 35 is U-shaped. This configuration allows for the limiting of the measuring plate 32.

[0033] Detailed Implementation: A tungsten-molybdenum rod is placed into the first placement groove 28 on the surface of the lower limit seat 24. Then, the second lead screw 25 is rotated at the top of the lower limit seat 24. Due to the restriction of the second guide rod 26 fixed at the top of the lower limit seat 24, the upper limit seat 27 moves down along the surface of the second lead screw 25 until it contacts the surface of the tungsten-molybdenum rod, thus limiting the tungsten-molybdenum rod. Since the distance between the lower limit seat 24 and the upper limit seat 27 is adjustable, the clamp can be adapted to various types of tungsten-molybdenum rods, thereby expanding the applicability of the clamp. After the tungsten-molybdenum rod is fixed, the first lead screw 22 is rotated to allow the connecting frame 2 fixed at the top of the base 1 to... 1. Rotate within the base. Due to the restriction of the first guide rod 23 fixed in the connecting frame 21, the lower limit seat 24 will slide along the top of the base 1 toward the second placement groove 38 opened in the positioning seat 37 until the tungsten molybdenum rod is inserted into it and abuts against its inner wall. At this time, the tungsten molybdenum rod can be cut to obtain a tungsten molybdenum rod of a specified length. Since the moving component 2 only fixes one end of the tungsten molybdenum rod, after the tungsten molybdenum rod is cut, the cut part is first taken out from the second placement groove 38, and then the lower limit seat 24 can be moved to cut the remaining tungsten molybdenum rod. The entire cutting process does not require repeated fixing of the tungsten molybdenum rod, which helps to improve the cutting efficiency.

[0034] Pulling the locking plate 35 upward causes it to drive several transmission rods 34 fixed at its top to slide along the inner wall of the connecting plate 33 and squeeze the return spring 36 until the locking plate 35 moves away from the measuring plate 32. Then, while keeping the locking plate 35 stationary, pull the measuring plate 32 so that it slides along the storage groove 31 opened in the base 1 until the measuring plate 32 extends to a suitable length. The cutting length of the tungsten molybdenum rod can be limited by the positioning seat 37 fixed to one end of the measuring plate 32. Finally, releasing the locking plate 35 allows it to reset under the action of the return spring 36, thus limiting the position of the measuring plate 32. Since the measuring plate 32 slides along the storage groove 31, the space occupied by the fixture can be reduced, which facilitates the transportation and storage of the fixture.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
