The preparation method of tungsten-molybdenum alloy is the same as that of metallic molybdenum materials and molybdenum alloys, namely powder metallurgy sintering and smelting. It can be used to produce rods, plates, wires or other profiles.

[0032] See also Figures 1-4As shown, height adjustment components 1 are installed on both sides of the top surface of the frame 3. Specifically, the height adjustment components 1 include L-shaped mounting brackets 102 and cylinder bodies 101. There are two L-shaped mounting brackets 102 and they are fixed upside down on both sides of the top surface of the frame 3. The horizontal parts of the top of the L-shaped mounting brackets 102 are suspended above the top surfaces of the U-shaped roller frame 201 on both sides, and the cylinder bodies 101 are vertically fixed on the top surfaces of the horizontal parts of the top of the L-shaped mounting brackets 102. The push rods 104 at the bottom of the cylinder bodies 101 They all pass through the bottom surface of the horizontal part of the corresponding L-shaped mounting frame 102 in a vertical sliding fit and the bottom end is coaxially fixed with a connecting sleeve 103. The connecting sleeve 103 is detachably connected to the side corresponding to the top surface of the U-shaped roller frame 201 through the disassembly and assembly assembly 5. The purpose of this arrangement is to facilitate the adjustment of the position height of the upper leveling clamping rod assembly 2 by driving the push rod 104 to extend and retract through the cylinder body 101 of the height adjustment assembly 1. The position height adjustment method of the upper leveling clamping rod assembly 2 is simple and easy to implement.

[0033] See also Figures 1-4As shown, the height adjustment components 1 at both sides are detachably connected to the top sides of the upper leveling clamping rod component 2 through the disassembly and assembly components 5, so as to adjust the position height of the upper leveling clamping rod component 2 by the height adjustment component 1. Specifically, the disassembly and assembly components 5 include a matching seat 504 and a fixed seat 506. The bottom end of the connecting sleeve 103 is vertically fixed with a matching seat 504. The inner end surfaces of the matching seats 504 at both sides are close to each other and have limiting holes 507 opened in the horizontal direction. The top surface of the U-shaped roller frame 201 is vertically fixed on both sides. The fixing seat 506 is fixed vertically, and the top surface of the fixing seat 506 is vertically provided with a matching groove 505. The matching groove 505 corresponds to the matching seat 504 one by one and is vertically slidably matched. The inner end surfaces of the fixing seats 506 at both sides are close to each other and are horizontally provided with mounting holes 508. The mounting holes 508 are vertically connected to the corresponding matching grooves 505, and the mounting holes 508 are horizontally coaxial with the corresponding limiting holes 507. The mounting holes 508 are horizontally coaxially slidably matched with the limiting rods 503, and the limiting rods 503 at both sides are aligned with each other. The outer ends of the two ends are fitted with the corresponding limiting holes 507 for horizontal sliding. The inner ends of the limiting rods 503 at both sides are close to each other and extend out of the inner end faces of the corresponding fixing seats 506 and are coaxially fixed with the handle 501. The part of the limiting rod 503 located between the corresponding handle 501 and the inner end face of the fixing seat 506 is fitted with a spring 502 in a coaxial gap, and the two ends of the spring 502 are fixedly connected to the corresponding handle 501 and the inner end face of the fixing seat 506 respectively. The function of this arrangement is to vertically rotate the locking nut 504 through the matching seat 504 and the matching groove 505. The sliding fit and the horizontal sliding fit between the limit rod 503 and the limit hole 507 can detachably connect the connecting sleeve 103 of the height adjustment component 1 and the U-shaped roller frame 201 of the upper leveling clamping rod assembly 2. At the same time, only the limit rod 503 needs to be pulled out of the limit hole 507 to make the matching seat 504 vertically disengage from the matching groove 505 to separate the connecting sleeve 103 of the height adjustment component 1 and the U-shaped roller frame 201 of the upper leveling clamping rod assembly 2 from each other. The combination and disassembly of the height adjustment component 1 and the upper leveling clamping rod assembly 2 are simple and easy to operate.

[0034] See also Figure 1-Figure 7 As shown, the height adjustment component 1 and the disassembly and assembly component 5 are optimized as follows. Specifically, for the height adjustment component 1, the two cylinder bodies 101 run synchronously, and the push rods 104 are coaxially interference fit with the corresponding connecting sleeves 103. Preferably, the connecting sleeves 103 are welded to the top surfaces of the corresponding matching seats 504. Such an arrangement first facilitates the two cylinder bodies 101 to synchronously and smoothly drive the U-shaped roller frame 201 to perform lifting and lowering adjustment operations, and at the same time facilitates the push rods 104 and the matching seats 504 to be quickly combined together through the connecting sleeves 103.

[0035] Specifically for the disassembly and assembly component 5, the horizontal cross-sectional shapes of the mating seat 504 and the mating groove 505 are both rectangular, so that the mating seat 504 and the mating groove 505 have a good positioning and guiding design when they slide vertically. At the same time, the optional mating grooves 505 are all blind grooves in the vertical direction, and the bottom ends of the mating seats 504 are in contact with the bottom ends of the corresponding mating grooves 505. With such an arrangement, in the process of vertical sliding cooperation between the mating seat 504 and the mating groove 505, when the mating groove 505 moves up along the mating seat 504 to the horizontal coaxial comparison between the limit rod 503 and the limit hole 507, an obvious prompt can be given by the way that the bottom end of the mating seat 504 is in contact with the bottom of the mating groove 505.

[0036] With the above structure, specifically in the process of leveling the tungsten-molybdenum plates, since the height adjustment components 1 are installed at the two sides of the frame 3, and the height adjustment components 1 are connected to the two side positions of the upper leveling clamping rod component 2 through the disassembly and assembly components 5, the position height of the upper leveling clamping rod component 2 can be adjusted by the cylinder body 101 of the height adjustment component 1 driving the push rod 104 to extend and retract. The position height adjustment method of the upper leveling clamping rod component 2 is simple and easy to implement, and then it is convenient to level tungsten-molybdenum plates of different thicknesses, thereby improving the applicability of the device. Specifically in operation, The cylinder body 101 is ventilated by being connected to the external air supply pipeline. The cylinder body 101 drives the upper leveling clamping rod assembly 2 to be raised and lowered by the extension of the push rod 104, so as to adjust the distance between the upper leveling clamping rod assembly 2 and the lower leveling clamping rod assembly 4, so as to adapt to the leveling of tungsten-molybdenum plates of different thicknesses. After the adjustment is completed, the drive motor 402 is powered on by being electrically connected to the external power supply cable. The drive motor 402 drives the lower leveling roller 401 to rotate through the motor shaft 405, so that the tungsten-molybdenum plate passes between the upper leveling clamping rod assembly 2 and the lower leveling clamping rod assembly 4. The leveling operation is performed, and specifically when it comes to the combination and disassembly operation of the height adjustment component 1 and the upper leveling clamping rod component 2, when they are combined, the connecting sleeve 103 of the height adjustment component 1 and the U-shaped roller frame 201 of the upper leveling clamping rod component 2 can be detachably connected together by means of the vertical sliding cooperation between the matching seat 504 and the matching groove 505 and the horizontal sliding cooperation between the limiting rod 503 and the limiting hole 507. The fixed combination method of the height adjustment component 1 and the upper leveling clamping rod component 2 is simple and easy to operate, and then it is convenient to combine the height adjustment component 1 and the upper leveling clamping rod component 2 together for leveling the tungsten-molybdenum plate, and when it is performed When disassembling, it is only necessary to simultaneously hold the handles 501 on both sides and pull outwards, and the limit rods 503 are pulled out of the limit holes 507 by the stretching of the springs 502, and then the matching seat 504 can be vertically disengaged from the matching groove 505 to separate the connecting sleeve 103 of the height adjustment assembly 1 and the U-shaped roller frame 201 of the upper leveling clamp assembly 2 from each other. The disassembly method of the height adjustment assembly 1 and the upper leveling clamp assembly 2 is simple and easy to operate, which makes it convenient to regularly inspect and correct the upper leveling clamp assembly 2 after it is disassembled.
