Description

Technical Field

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

[0002] Tungsten-molybdenum rods are widely used in electronics, metallurgy, aerospace and other fields due to their high melting point, excellent thermal conductivity and low thermal expansion performance. In the prior art, the processing of tungsten-molybdenum rods usually adopts a one-time continuous forging process through multiple rotary forging machines after heating. This process can gradually process tungsten-molybdenum rods with a diameter of 10mm-20mm to 3mm-4mm, but this method has some inherent problems in the implementation process.

[0003] During the rotary forging process, the tungsten-molybdenum rod needs to overcome the resistance of the rotary forging die when entering the rotary forging die, which will cause the end of the tungsten-molybdenum rod to bend. This bending not only affects the subsequent processing steps, but especially during the annealing process, the bent end is easy to contact with the induction coil, causing sparking, thereby destroying the stability of the annealing process. In addition, the bent end will cause material waste during the processing of the tungsten-molybdenum rod, reducing the yield and overall quality of the finished product. In addition, the corrosion treatment of the tungsten-molybdenum rod usually requires it to be inserted into a groove containing a corrosive agent. This process is not only time-consuming but also affects the continuity of the processing process, resulting in a decrease in process efficiency.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The present embodiment provides a tungsten-molybdenum rod processing device, including a base plate 1, on which a rotary forging mechanism, a heating mechanism, a rotary forging straightening mechanism and a corrosion mechanism are arranged.

The rotary forging straightening mechanism is used to process the end of the tungsten-molybdenum rod 39 to eliminate the stress of the tungsten-molybdenum rod 39 and complete the straightening of the tungsten-molybdenum rod 39.

[0031] When processing the tungsten-molybdenum rod 39, the tungsten-molybdenum rod 39 is rotary forged by a rotary forging mechanism, the tungsten-molybdenum rod 39 is heat treated by a heating mechanism, the rotary forging and straightening mechanism is used to further rotary forge and straighten the tungsten-molybdenum rod 39, and the corrosion mechanism is used to corrode the tungsten-molybdenum rod 39.

[0032] The rotary forging and straightening mechanism includes a rotary forging correction box 34, which is fixedly mounted on the base plate 1. Two symmetrically arranged clamping assemblies are fixedly mounted on the rotary forging correction box 34. The clamping assemblies include multiple circumferentially arranged electric cylinders 35. A clamping block 36 is fixedly mounted on the protruding end of each electric cylinder 35. A cylinder 37 is detachably mounted at the center of the rotary forging correction box 34. A sleeve 2 38 is fixedly mounted coaxially inside the cylinder 37. The sleeve 2 38 is used to eliminate the stress of the tungsten-molybdenum rod 39 and straighten the tungsten-molybdenum rod 39.

[0033] like Figure 1 , Figure 2 As shown, two symmetrically arranged clamping assemblies are provided on the rotary swaging correction box 34 in the rotary swaging straightening mechanism. The clamping assemblies are used to fix the cylinder 37 and the sleeve 2 38 in the center of the rotary swaging correction box 34. When the cylinder 37 and the sleeve 2 38 are replaced, the cylinder 37 can be taken out of the rotary swaging correction box 34 by only loosening the clamping assembly.

[0034] like Fig. 9 , Fig.10 As shown, each clamping assembly includes three electric cylinders 35 arranged in a circle, and a clamping block 36 is fixedly installed on the protruding end of each electric cylinder 35. The side of the clamping block 36 close to the cylinder 37 is arc-shaped.

[0036] like Figure 1 , Figure 2 and Figure 3As shown, the straightening components are linearly arranged above the base plate 1, and the distance between the upper straightening roller 9 and the lower straightening roller 10 in each straightening component is adjustable. The specific adjustment method is to start the cylinder 12 fixedly installed on the vertical plate 13, so that the extended end of the cylinder 12 drives the connecting head 11 to move, thereby driving the upper straightening roller 9 to slide upward or downward on the guide groove 14 through the connecting head 11 to adjust the distance between the upper straightening roller 9 and the lower straightening roller 10. The purpose of this is to meet the needs of tungsten-molybdenum rods 39 of different diameters.

[0037] The conveying assembly includes a moving plate 8 slidably mounted on the bottom plate 1, a feeding rack 5 is fixedly mounted on the moving plate 8, the feeding rack 5 is meshed with the feeding gear 4, the feeding gear 4 is coaxially fixedly connected to the central shaft 7, and the central shaft 7 is fixedly connected to the output shaft of the motor 6, and the motor 6 is fixedly mounted on the bottom plate 1. The conveying assembly also includes a friction wheel 3 and an electromagnetic chuck 33, the friction wheel 3 is coaxially fixedly connected to the central shaft 7, and the electromagnetic chuck 33 is fixedly mounted on the moving plate 8.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the conveying assembly is located above the base plate 1, and when the tungsten-molybdenum rod 39 is processed, the electromagnetic chuck 33 can clamp the tungsten-molybdenum rod 39, and the electromagnetic chuck 33 and the tungsten-molybdenum rod 39 are driven to move by the movement of the movable plate 8, and the friction wheel 3 is located below the tungsten-molybdenum rod 39, and the friction wheel 3 drives the tungsten-molybdenum rod 39 to move through friction. Of course, in order to increase the friction between the friction wheel 3 and the tungsten-molybdenum rod 39, the outer ring of the friction wheel 3 can be set to be frosted.

[0039] The heating mechanism comprises a heating furnace 15 , which is fixedly mounted on the bottom plate 1 , and is used for heat treatment of the tungsten-molybdenum rod 39 .

[0040] like Figure 1 , Figure 2 As shown, the heating furnace 15 is fixedly installed above the bottom plate 1 , and an electric heating wire can be added inside the heating furnace 15 . By heating the electric heating wire, a high temperature is generated inside the heating furnace 15 , thereby heat treating the tungsten-molybdenum rod 39 .

[0041] The corrosion mechanism includes a treatment box 17 fixedly mounted on the bottom plate 1, an anti-overflow box 16 fixedly mounted above the treatment box 17, and the anti-overflow box 16 is connected to the heating furnace 15 via a heat conducting sheet. The anti-overflow box 16 and the treatment box 17 are connected via two collecting pipes 18, a center plate 21 is fixedly mounted inside the anti-overflow box 16, and lifting plates 19 are slidably mounted on both sides of the center plate 21, and a U-shaped groove 20 is provided on the lifting plate 19, and the U-shaped groove 20 is slidably matched with a guide plate 30 fixedly mounted inside the anti-overflow box 16, and a wedge block 31 is installed below the anti-overflow box 16, and potassium nitrite is filled inside the anti-overflow box 16.

[0042] like Figure 4 , Figure 7 and Figure 8 As shown, the anti-overflow box 16 is located above the processing box 17, and the anti-overflow box 16 and the processing box 17 are connected by a collecting pipe 18. The function of the collecting pipe 18 is that when the potassium nitrite in the processing box 17 overflows and flows to the bottom of the anti-overflow box 16, the potassium nitrite that enters the bottom of the anti-overflow box 16 can flow back to the processing box 17 through the collecting pipe 18, which can effectively avoid waste. In addition, holes that allow tungsten-molybdenum rods 39 to pass through are provided at the same height on the processing box 17 and the anti-overflow box 16. After the tungsten-molybdenum rods 39 enter the processing box 17, they are corroded by the potassium nitrite in the processing box 17.

[0043] The corrosion mechanism also includes two relatively arranged pushing components, which include a ball head rod 26 that slides with the processing box 17, one end of the ball head rod 26 slides with the wedge block 31, and the other end of the ball head rod 26 is fixedly connected to a pushing rack 24 that is slidably mounted on the base plate 1. A reset spring 25 is arranged between the pushing rack 24 and the processing box 17, and the reset spring 25 is connected to the linear motion component, and the linear motion component is connected to the friction wheel 22. The friction wheel 22 is rotatably mounted on the base plate 1, and the friction wheel 22 is located below the tungsten-molybdenum rod 39.

[0044] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the linear motion assembly includes a gear set 23 and a belt assembly 32. The gear set 23 is installed on the base plate 1. The gear set 23 includes two cylindrical gears that mesh with each other, one cylindrical gear is connected to the friction wheel 22, and the other cylindrical gear is meshed with the push rack 24; the belt assembly 32 is installed on the base plate 1, and the belt assembly 32 includes two pulleys and a belt. The two pulleys are connected by a belt, one pulley is connected to the friction wheel 22, and the shaft where the other pulley is located is connected with an output gear, and the output gear is meshed with the push rack 24.

[0045] A sleeve 27 is fixedly mounted on the pushing rack 24, and the sleeve 27 is slidably matched with the positioning rod 28. A reset spring 2 is arranged between the positioning rod 28 and the sleeve 27. The end of the positioning rod 28 away from the sleeve 27 is slidably matched with a positioning plate 29 fixedly mounted on the base plate 1. The positioning plate 29 is provided with a positioning hole. When the positioning rod 28 slides along the positioning plate 29 to the position of the positioning hole, the positioning rod 28 slides along the sleeve 27 under the action of the reset spring 2 and extends into the positioning hole.

[0046] Working principle: According to the diameter of the processed tungsten-molybdenum rod 39, the distance between the multiple upper straightening rollers 9 and the lower straightening rollers 10 is adjusted. Specifically, the cylinder 12 is started so that the protruding end of the cylinder 12 drives the connecting head 11 to move, so that the upper straightening roller 9 rotatably connected to the connecting head 11 can slide on the guide groove 14, thereby completing the distance adjustment between the upper straightening roller 9 and the lower straightening roller 10; at the same time, according to the diameter of the tungsten-molybdenum rod 39, the diameter of the sleeve 2 38 installed in the rotary forging correction box 34 is adaptively adjusted, and the diameter of the sleeve 2 38 is two millimeters larger than the diameter of the tungsten-molybdenum rod 39. After the replacement is completed, the electric cylinder 35 fixedly installed on the rotary forging correction box 34 is started, so that the protruding end of the electric cylinder 35 pushes the clamping block 36, and the cylinder 37 is clamped by the clamping block 36, and then the tungsten-molybdenum rod 39 is started.

[0047] When processing the tungsten-molybdenum rod 39, first place the tungsten-molybdenum rod 39 on the electromagnetic chuck 33. Of course, for the stability of the actual work, multiple electromagnetic chucks 33 can be set to work simultaneously, which is conceivable for those skilled in the art. The tungsten-molybdenum rod 39 is fixed by the electromagnetic chuck 33. Start the motor 6 fixedly installed on the bottom plate 1, and drive the central shaft 7 fixedly connected to the output shaft to rotate through the output shaft of the motor 6, so that the friction wheel 3 and the feed gear 4 on the central shaft 7 will rotate, and the feed gear 4 rotates, so that the feed rack 5 meshing with the feed gear 4 can move. At this time, the moving plate 8 fixedly connected to the feed rack 5 will slide on the bottom plate 1, thereby driving the tungsten-molybdenum rod 39 to move through the electromagnetic chuck 33 on the bottom plate 1, and the tungsten-molybdenum rod 39 is transported to the rotary forging machine 2, and the tungsten-molybdenum rod 39 is rotary forged by the rotary forging machine 2 until the diameter of the tungsten-molybdenum rod 39 is slightly smaller than the diameter of the wire drawing die.

[0048] After the rotary forging process is completed, the electromagnetic chuck 33 loosens the tungsten-molybdenum rod 39. At this time, the electromagnetic chuck 33 only supports the tungsten-molybdenum rod 39, and then the motor 6 is reversed, so that the output shaft of the motor 6 drives the central shaft 7 to reverse. At this time, the friction wheel 13 on the central shaft 7 drives the tungsten-molybdenum rod 39 on the friction wheel 13 to move through the friction force. First, the tungsten-molybdenum rod 39 is transported to the sleeve 2 38, so that the tungsten-molybdenum rod 39 passes through the sleeve 2 38 completely, thereby straightening the tungsten-molybdenum rod 39 and the end of the tungsten-molybdenum rod 39, and eliminating the stress on the tungsten-molybdenum rod 39. It should be noted that the upper straightening roller 9 and the lower straightening roller 10 also have the function of straightening the tungsten-molybdenum rod 39.

[0049] After the tungsten-molybdenum rod 39 passes through the sleeve 38 and comes out, it will enter the heating furnace 15, and the tungsten-molybdenum rod 39 will be heat-treated by the heating furnace 15. The electric cylinder 35 is provided with a heating wire, and the tungsten-molybdenum rod 39 can be heated by the heating wire. At the same time, a heat conductive sheet is provided between the heating furnace 15 and the anti-overflow box 16. When the potassium nitrite in the processing box 17 overflows into the anti-overflow box 16, the heat of the potassium nitrite in the anti-overflow box 16 can be transferred to the heating furnace 15, so that the heat can be utilized.

[0050] After the tungsten-molybdenum rod 39 comes out of the heating furnace 15, it will be corroded. First, the tungsten-molybdenum rod 39 will contact the friction wheel 22 near the side of the gear set 23. The friction between the tungsten-molybdenum rod 39 and the friction wheel 22 will drive the friction wheel 22 to rotate. At this time, the gear set 23 connected to the friction wheel 22 will move, so that the gear set 23 drives the push rack 24 to slide on the bottom plate 1, so that the ball head rod 26 fixedly connected to the push rack 24 will slide to the side close to the overflow box 16, so that the ball head rod 26 pushes the wedge block 31, and the wedge block 31 drives the lifting plate 19 near the side of the gear set 23 to rise, so that the lifting plate 19 pushes the potassium nitrite upward, so that the potassium nitrite contacts the tungsten-molybdenum rod 39, and the corrosion of the tungsten-molybdenum rod 39 is completed; in the process of the tungsten-molybdenum rod 39 continuing to move forward, the tungsten-molybdenum rod 39 After 39 passes through the hole on the anti-overflow box 16, it will contact the friction wheel 22 close to the side of the belt assembly 32. At the same time, the friction wheel 22 drives the belt assembly 32 to move, so that the belt assembly 32 drives the pushing rack 24 close to the side of the belt assembly 32 to move, and also makes the lifting plate 19 close to the side of the belt assembly 32 rise, thereby pushing the potassium nitrite upward and corroding the tungsten-molybdenum rod 39. In this way, on the one hand, the tungsten-molybdenum rod 39 can be corroded more evenly, and on the other hand, potassium nitrite can be prevented from overflowing from the processing box 17 into the anti-overflow box 16. Even if potassium nitrite overflows, it will flow back to the processing box 17 through the collection pipe 18 between the anti-overflow box 16 and the processing box 17, thereby completing recovery and utilization.

[0051] In addition, the U-shaped groove 20 provided on the lifting plate 19 is slidably matched with the guide plate 30 fixedly installed in the processing box 17. When the lifting plate 19 moves to the bottom of the guide plate 30, the potassium nitrite below the lifting plate 19 will be squeezed to the top of the lifting plate 19 through the gap between the U-shaped groove 20 and the guide plate 30, thereby corroding the tungsten-molybdenum rod 39 after the lifting plate 19 rises.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. 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. Although the present invention has been described in detail with reference to the above embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the above embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
