Description

Technical Field

[0001] The invention belongs to the technical field of tungsten-molybdenum rod production equipment, and in particular relates to a six-station continuous processing device for tungsten-molybdenum rod production. Background Art

[0002] Traditional tungsten and molybdenum rod processing methods mainly include wire drawing, rotary forging, surface treatment and heat treatment. These steps usually require multiple separate equipment, and each processing step requires manual or mechanical transfer, which not only increases production costs, but also reduces processing efficiency and consistency. In the current technical context, although there are some advanced processing devices that can achieve multi-step processing, these devices can usually only complete continuous processing of a few steps.

[0003] For tungsten wire products that require high-precision and multi-step processing, the processing capacity and efficiency of these devices are still limited. In the prior art, the distance between the heat treatment and swaging components will cause heat loss in the heat-treated tungsten-molybdenum rods, which not only affects product quality, but may also pose a threat to the safety of workers. In addition, the continuous processing of tungsten-molybdenum rods involves maintaining the stability of the material during the processing process and controlling the processing accuracy. If continuous processing cannot be achieved, frequent repositioning will significantly affect the processing accuracy. Summary of the invention

DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0030] The following description is used to explain the technical solution of the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other implementation schemes, variations, improvements, equivalent solutions, and other technical solutions that do not deviate from the spirit and scope of the present invention. At the same time, it is worth noting that the features or characteristics described in the text in conjunction with a certain embodiment are not necessarily limited to this specific embodiment, nor are they mutually exclusive with other embodiments. Within the scope of the capabilities of those skilled in the art, different combinations of various features in different embodiments can be considered.

[0031] like Figure 1 — Figure 8 As shown, this embodiment discloses a six-station continuous processing device for the production of tungsten-molybdenum rods, including a support base 1; six processing mechanisms are installed on the support base 1 and arranged linearly, and each processing mechanism includes a heating component 2, a heat preservation component 3 and a rotary forging component 4. The heating component 2 is used to heat the tungsten-molybdenum rod. The heat preservation component 3 is located between the heating component 2 and the rotary forging component 4, and the heat preservation component 3 is used to keep the heated tungsten-molybdenum rods warm. The rotary forging component 4 includes a rotary forging machine and a straightening part arranged at the discharge end of the rotary forging machine, the rotary forging machine is used to rotary forge the tungsten-molybdenum rod, and the straightening part is used to eliminate the stress of the tungsten-molybdenum rod and straighten the end of the tungsten-molybdenum rod.

[0032] like Figure 1 and Figure 2 As shown, six processing mechanisms are arranged linearly on the support seat 1, and each identical mechanism is composed of a heating component 2, a heat preservation component 3, and a rotary forging component 4 arranged in sequence. When processing the tungsten-molybdenum rod, the tungsten-molybdenum rod will pass through the six processing structures in sequence. The heating component 2 can generate heat by heating the heating wire, which belongs to the prior art and can be realized by those skilled in the art.

[0033] The insulation component 3 includes an insulation tube 301 fixedly mounted on the support seat 1, an insulation tube 307 is coaxially arranged inside the insulation tube 301, a first air inlet hole 306 is arranged on the insulation tube 301, the first air inlet hole 306 is fixedly connected to one end of the air inlet pipe 304, the other end of the air inlet pipe 304 is connected to the air storage box 303, and an electromagnetic valve is arranged on the air inlet pipe 304, one end of the heat conduction pipe 302 is connected to the air storage box 303, and the other end of the heat conduction pipe 302 is connected to the heating component 2.

[0034] like Figure 3As shown, the heat pipe 302, the air storage box 303 and the air intake pipe 304 are located outside the insulation tube 301. In actual use, the end of the heat pipe 302 away from the air storage box 303 is connected to the heating component 2. When heat is generated in the heating component 2, the heat will enter the heat pipe 302 through the heating component 2 to heat the gas in the air storage box 303. A one-way valve is provided between the heat pipe 302 and the air storage box 303, that is, the gas in the air storage box 303 will not enter the heat pipe 302. The air storage box 303 stores inert gases such as nitrogen. A solenoid valve is provided inside the air intake pipe 304. When it is necessary to transport gas to the insulation tube 301, the solenoid valve is opened, and the inert gas stored in the air storage box 303 will enter the insulation tube 301 through the air intake pipe 304.

[0035] The outer wall of the insulation tube 307 is provided with a spiral sheet 309, and a plurality of second air inlet holes 308 are provided on the insulation tube 307 along the central axis direction. When the gas in the air storage box 303 enters the insulation tube 301 through the air inlet pipe 304 and the first air inlet hole 306, the gas will enter the insulation tube 307 through the second air inlet hole 308.

[0036] like Figure 4 , Figure 5 As shown, a second air inlet hole 308 on the insulation tube 307 is located below the first air inlet hole 306. When the solenoid valve is opened to supply air to the insulation tube 301, the gas will flow along the spiral blade 309, thereby expanding the heated area and increasing the fluidity of the gas. The spiral blade 309 plays a guiding role. On the other hand, the gas will enter into a plurality of second air inlet holes 308 arranged linearly in sequence.

[0037] The insulation component 3 also includes an inner cylinder 310, which is coaxially rotatably installed inside the insulation cylinder 307. Four groups of air outlets are arranged linearly on the inner cylinder 310, each group of air outlets is composed of a plurality of air outlet holes 311 arranged linearly, and the diameters of the air outlet holes 311 in each two adjacent groups of air outlets are different.

[0038] like Figure 6 As shown, four groups of gas outlets are provided on the inner cylinder 310, and each group of gas outlets includes a plurality of gas outlet holes 311 arranged linearly. When the solenoid valve is opened for gas supply, a group of gas outlet holes 311 with a certain diameter is selected to coincide with the second gas inlet hole 308 in the heat preservation cylinder 307 as required, so that the gas will pass through the second gas inlet hole 308 and the gas outlet holes 311 into the inner cylinder 310, so that the tungsten-molybdenum rod passing through the inner cylinder 310 is in a nitrogen environment, reducing the reaction with oxygen. By providing gas outlet holes 311 with different diameters, the gas outlet holes 311 with a suitable diameter can be selected according to the actual diameter of the tungsten-molybdenum rod, thereby controlling the amount of nitrogen introduced.

[0039] An end cover 305 is fixedly installed at one end of the insulation tube 301, and a conversion gear 312 is rotatably installed at the other end of the insulation tube 301. The end cover 305 is fixedly connected to the insulation tube 307, and the conversion gear 312 is fixedly connected to one end of the air outlet 311. The conversion gear 312 is meshed with the cylindrical gear 313, and the cylindrical gear 313 is fixedly connected to the output shaft of the motor 314.

[0040] like Figure 2 , Figure 3 , Figure 6 As shown, when the inner cylinder 310 needs to rotate inside the heat preservation cylinder 307 to adjust the diameter of the air outlet hole 311 that overlaps with the second air inlet hole 308, the motor 314 fixedly mounted on the support base 1 is started, so that the output shaft of the motor 314 drives the cylindrical gear 313 to rotate, so that the conversion gear 312 meshing with the cylindrical gear 313 rotates, and the conversion gear 312 drives the inner cylinder 310 to rotate. In this way, the air outlet holes 311 of different diameters can be adjusted to overlap with the second air inlet hole 308.

[0041] The rotary swaging assembly 4 includes a rotary swaging machine and a straightening part arranged at the discharge end of the rotary swaging machine. The rotary swaging machine is used to rotary swage the tungsten-molybdenum rod, and the straightening part is used to eliminate the stress of the tungsten-molybdenum rod and straighten the end of the tungsten-molybdenum rod. Specifically, the straightening part includes a shell 401 fixedly mounted on the support seat 1, a center tube 404 is detachably mounted inside the shell 401, a sleeve 405 is coaxially mounted on the center tube 404, and the center tube 404 and the sleeve 405 are used to straighten the tungsten-molybdenum rod and eliminate the stress on the tungsten-molybdenum rod.

[0042] After the tungsten rod is forged through the rotary forging assembly 4, the end portion will be bent and have residual stress, so the end portion needs to be straightened and the stress eliminated.

[0043] The two oppositely arranged surfaces of the shell 401 are provided with clamping assemblies, which include three cylinders 402 fixedly mounted on the shell 401. The extended end of each cylinder 402 is fixedly connected to the clamping plate 403, and the end of the clamping plate 403 close to the sleeve 405 is arc-shaped.

[0044] like Figure 7 , Figure 8 As shown, the purpose of the arc-shaped clamping plate 403 is to better clamp the sleeve 405 and the center tube 404 .

[0045] The inner diameters of the six central tubes 404 in the six processing mechanisms decrease sequentially, and the inner diameter of the sleeve 405 installed inside the central tube 404 also decreases sequentially.

[0046] As the tungsten-molybdenum rod is gradually processed, the diameter of the tungsten-molybdenum rod after the first processing mechanism will be larger than the diameter of the tungsten-molybdenum rod after the sixth processing mechanism, so it is necessary to flexibly adjust the diameters of the center tube 404 and the sleeve 405 according to the diameter change of the tungsten-molybdenum rod, so as to better straighten the tungsten-molybdenum rod. Of course, according to this, those skilled in the art can set the diameters of the six inner tubes 310 to a state of decreasing in sequence according to actual needs, so as to meet the diameters of the tungsten-molybdenum rods at different processing stages.

[0047] Six feeding mechanisms are also arranged on the support seat 1. The feeding mechanism consists of two symmetrically arranged feeding roller 5 assemblies. The rotation of the feeding roller 5 drives the tungsten-molybdenum rod located between the two feeding rollers 5 to move, and the distance between the two feeding rollers 5 in each feeding mechanism decreases successively.

[0048] like Figure 1 , Figure 2 As shown, as the tungsten-molybdenum rod is gradually processed, the diameter will decrease successively, so it is necessary to adjust the distance between the two feeding rollers 5 to meet the needs of different tungsten-molybdenum rods.

[0049] In this embodiment, six rotary forging processes are performed on tungsten-molybdenum rods with a diameter of less than 6.0 mm, and the compression ratio of each rotary forging is set as follows: the first and second times are 13-15%, the third and fourth times are 16-18%, the fifth time is 18-19%, and the last time is 16-18%. Through this series of rotary forging processes, a tungsten wire that meets the requirements is finally obtained.

[0050] The working principle of this embodiment is as follows: before processing the tungsten-molybdenum rod, according to the diameter of the tungsten-molybdenum rod, the diameter of the sleeve 405 in the six shells 401 is adaptively adjusted. Because the center tube 404 and the shell 401 are detachable, when replacing the sleeve 405, the center tube 404 with the sleeve 405 installed is removed from the shell 401, and then the sleeve 405 with a suitable diameter is installed on the shell 401 through the center tube 404. The center tube 404 and the shell 401 can be connected by bolts, or fixed by screws and other common methods. Figure 1 The distance between the six sleeves 405 from left to right decreases in sequence, because during the processing of the tungsten-molybdenum rod, the diameter of the tungsten-molybdenum rod will gradually decrease from the left side to the right side, so correspondingly, the inner diameter of the sleeve 405 also needs to be gradually reduced. After the sleeve 405 is replaced, the cylinder 402 fixedly mounted on the housing 401 is started, so that the extended end of the cylinder 402 drives the clamping plate 403 to approach the center tube 404 and the sleeve 405, and finally the clamping plate 403 clamps the center tube 404 and the sleeve 405 to prevent the center tube 404 from loosening. Since the side of the clamping plate 403 close to the center tube 404 is a curved surface, it can be fixed more tightly.

[0051] First, the tungsten-molybdenum rod is placed in the heating assembly 2, and the tungsten-molybdenum rod is heat-treated by the heating assembly 2. The heating assembly 2 is provided with a heating wire that can generate heat. When the heating wire is energized, heat can be generated to heat-treat the tungsten-molybdenum rod. After the tungsten-molybdenum rod is heat-treated by the heating assembly 2, it will enter the inner cylinder 310 coaxially arranged with the insulation cylinder 301. The insulation cylinder 301 and the inner cylinder 310 are both made of insulation materials, which can prevent the temperature of the heat-treated tungsten-molybdenum rod itself from dropping rapidly, thereby ensuring the performance of the tungsten-molybdenum rod. In addition, the heat pipe 302 is connected to the heating assembly 2, and the heat of the heating assembly 2 can be transferred to the insulation cylinder 301 through the heat pipe 302, the air intake pipe 304, etc., to realize the utilization of heat. When it is necessary to isolate the surface of the tungsten-molybdenum rod from oxygen to prevent oxidation, the solenoid valve on the air inlet pipe 304 is started and opened to allow the inert gas in the air storage box 303, such as nitrogen, to enter the air inlet pipe 304 and enter the heat insulation cylinder 301 through the solenoid valve and the first air inlet hole 306. At this time, the gas will move along the spiral spiral sheet 309, generate an automatic speed, and then pass through the second air inlet hole 308 arranged linearly. Since the heat preservation cylinder 307 and the inner cylinder 310 rotate in coordination, the gas will be discharged through the air outlet hole 311 on the inner cylinder 310 after passing through the second air inlet hole 308. At this time, the nitrogen will occupy the part of the tungsten-molybdenum rod located inside the inner cylinder 310, thereby gradually changing the gas environment inside the inner cylinder 310 to a state with the highest nitrogen content, thereby preventing the tungsten-molybdenum rod from reacting with oxygen. Of course, according to the tungsten-molybdenum rods of different diameters, the flow rate of nitrogen entering the inner cylinder 310 can be flexibly adjusted. Specifically, the motor 314 fixedly mounted on the support seat 1 is started to rotate the cylindrical gear 313 fixedly mounted on the output shaft of the motor 314. Since the cylindrical gear 313 is meshed with the conversion gear 312, the conversion gear 312 will rotate on the heat-insulating cylinder 301. At this time, the inner cylinder 310 fixedly connected to the conversion gear 312 will rotate. Since the diameters of the four groups of linearly arranged air outlet holes 311 on the inner cylinder 310 are different from each other (such as Figure 6 ), so by selecting outlet holes 311 of different diameters to coincide with the second air inlet hole 308 in a one-to-one manner, the flow rate of nitrogen entering the inner cylinder 310 through the second air inlet hole 308 and the outlet holes 311 can be adjusted, thereby better achieving the purpose of preventing the surface of the tungsten-molybdenum rod from being oxidized. It should be noted that the diameter of the largest outlet hole 311 on the inner cylinder 310 is less than or equal to the diameter of the second air inlet hole 308.

[0052] By setting the heat preservation component 3 between the heating component 2 and the rotary swaging component 4, the temperature loss of the tungsten-molybdenum rod and the oxidation reaction on the surface can be prevented, which will affect the quality of the tungsten-molybdenum rod. The tungsten-molybdenum rod passes through the heat preservation component 3 and reaches the rotary swaging component 4, and is rotary swaged by the rotary swaging component 4. Then, it is straightened and stress is eliminated by the straightening part. In this way, the tungsten-molybdenum rod can be processed once, and then the tungsten-molybdenum rod that has been processed once is transported to the next processing mechanism through the feeding roller 5, so that the tungsten-molybdenum rod can be processed six times in succession, which greatly improves the production efficiency of the tungsten-molybdenum rod.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may also be combined, the steps may be implemented in any order, and there are many other changes in different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
