Description

Technical Field

[0001] The present application relates to the technical field of titanium metal welding, and in particular to a titanium alloy welding software warehouse. Background Art

[0002] Titanium is one of the welding materials. Due to its excellent properties such as low alloy density, high strength and corrosion resistance, it is widely used in the aviation industry, space navigation, and manufacturing of navigation equipment and other technical fields. However, since titanium metal has a high affinity with oxygen and is highly chemically active in high temperature environments, it is very easy to oxidize during the welding process. During the welding process, oxygen and nitrogen in the air are interstitially dissolved in titanium, causing the titanium lattice to distort, deformation resistance, strength, and hardness to increase, but plasticity and toughness to decrease, so it is necessary to try to avoid this.

[0003] At present, a Chinese patent with the announcement number CN117245287A discloses a titanium alloy vacuum welding chamber, including a welding chamber body, a plurality of connecting rings are arranged on the welding chamber body, a fixing ring is connected to the connecting ring, a sealed operating glove is connected to the inner ring of the fixing ring, a vent is arranged on the fixing ring, a plugging assembly for plugging the fixing ring is arranged on the fixing ring, and a plurality of observation windows are also arranged on the welding chamber body. When using it, the workpiece to be processed and welded is first placed inside the chamber body, and the chamber body is vacuumed and filled with argon gas in turn, and the operator welds the workpiece by inserting his hand into the operating glove.

[0004] With regard to the above-mentioned related technologies, the inventors believe that during the use of the above-mentioned titanium alloy vacuum welding chamber, since the chamber body is made of hard material, it is difficult to intuitively observe the vacuuming of oxygen and the filling of argon during the process of vacuuming and filling with argon. During operation, there may be insufficient oxygen discharge or insufficient argon filling, resulting in a decrease in welding quality. Summary of the invention

[0005] In order to improve the quality of titanium alloy welding, the present application provides a titanium alloy welding software warehouse.

[0006] The titanium alloy welding software warehouse provided in this application adopts the following technical solution: A titanium alloy welding software chamber comprises a welding chamber and a soft film, a mounting top frame is arranged at the top of the welding chamber, the soft film is connected to the mounting top frame, one side of the soft film is arranged toward the inner cavity of the welding chamber, an inflation tube and a vacuum tube are connected to the welding chamber, an argon gas cylinder is connected to the end of the inflation tube away from the welding chamber, an inflation pump is arranged on the inflation tube, a vacuum pump is connected to the end of the vacuum tube away from the welding chamber, a connecting port is opened on the welding chamber, and an operating glove is connected to the inner wall of the connecting port.

[0007] By adopting the above technical solution, when processing the workpiece, the workpiece is placed in the welding chamber, the vacuum pump is started to evacuate the welding chamber, and the soft film is concave inward. After the vacuum operation is completed, the argon gas in the argon gas cylinder is injected into the welding chamber using an air pump, and the soft film expands and bulges outward. Through the mutual cooperation of the welding chamber and the soft film, the inflation and vacuum degree of the welding chamber can be observed intuitively, and the setting of the soft film facilitates the inflation and deflation process, which has the effect of improving the quality of titanium alloy welding.

[0008] Optionally, a support frame is provided on the mounting top frame, and one of the support frames is symmetrically provided on the upper and lower sides of the mounting top frame, and the soft film is provided between the two support frames, and the support frame includes a limiting side plate, a supporting inclined frame and a supporting cross frame, and one of the limiting side plates is vertically and parallelly connected to the inner ring wall at both ends of the length direction of the mounting top frame, and one of the supporting inclined frames is obliquely provided on the inner walls at both ends of the width direction of the mounting top frame, and the supporting cross frame is horizontally connected between the two corresponding supporting oblique frames, and the opposite ends of the supporting cross frame correspond to the two limiting side plates one by one and are fitted together, the support frame located above the mounting top frame protrudes upward, and the support frame located below the mounting top frame is recessed downward.

[0009] By adopting the above technical solution, the supporting cross frame, the supporting inclined frame and the two limiting side plates simultaneously constitute a supporting frame, and the supporting frame is symmetrically arranged on both sides of the opposite sides of the soft film, thereby limiting the expansion and contraction degree of the soft film and reducing the possibility of the soft film bursting due to excessive expansion or contraction, thereby affecting the safety of operation.

[0013] By adopting the above technical solution, when the soft film is inflated and expanded to abut against the first control switch, the inflation pump stops inflating under the action of the signal.

[0014] Optionally, the mounting top frame includes an upper clamping frame and a lower clamping frame, one side of the upper clamping frame is rotatably connected to the lower clamping frame, the upper clamping frame and the lower clamping frame are connected by a buckle, and a circumferentially arranged accommodating ring cavity is provided on the side where the upper clamping frame and the lower clamping frame are close to each other, and an annular connecting ring is circumferentially arranged in the accommodating ring cavity of the lower clamping frame, and an airtight zipper is circumferentially arranged on the inner circle of the annular connecting ring, and the edge of the soft film is connected to the annular connecting ring through the airtight zipper, and an airtight rubber ring is circumferentially arranged on the inner circle of the side where the upper clamping frame and the lower clamping frame are close to each other, and the two airtight rubber rings correspond one by one and abut against the two sides of the soft film.

[0015] By adopting the above technical solution, the upper clamp frame and the lower clamp frame simultaneously clamp the soft film therebetween, and the provision of the airtight rubber ring improves the sealing of the welding chamber and reduces the possibility of air leakage.

During the inflation process, the cooling coil starts to reduce the temperature of the welding chamber, which helps to input more argon gas into the welding chamber and improve the protection effect of the welding process.

[0018] Optionally, two sealing plates are rotatably provided on the outer wall of the welding chamber, the two sealing plates are arranged in one-to-one correspondence with the two connecting ports, a connecting plate is connected between the two sealing plates, and a rotating limit rod for fixing the connecting plate is rotatably provided on the vertical outer wall of the welding bin, and when the sealing plate is rotated to correspond to the connecting port, the rotating limit rod corresponds to the position of the connecting plate.

[0019] By adopting the above technical solution, during the vacuuming operation, the two sealing plates are covered on the connecting port, and the rotation limit rod is rotated to limit the connection plate, thereby isolating the operating gloves from the external environment.

[0021] By adopting the above technical solution, the setting of the extended protective tube avoids the operating gloves from being ejected back out of the welding chamber under the action of air pressure after the sealing plate is opened, thereby affecting the normal use of the operator.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the cooperation between the welding chamber and the soft film, the inflation and vacuum degree of the welding chamber can be observed intuitively. The setting of the soft film facilitates the inflation and deflation process, which has the effect of improving the quality of titanium alloy welding; 2.

[0034] Reference Figure 2 and Figure 6, one support frame 3 is symmetrically arranged on the upper and lower sides of the mounting top frame 9, and the soft film 2 is sandwiched between the two support frames 3. The support frame 3 includes a limiting side plate 31, a supporting oblique frame 32, a supporting cross frame 33, an adjusting slider 34, an adjusting screw 35, a mounting plate 36 and an adjusting handle 37. One limiting side plate 31 is vertically fixedly connected to the inner circle at both ends of the mounting top frame 9 in the length direction, and a plurality of reinforcing ribs 10 for strengthening the supporting strength of the limiting side plate 31 are vertically fixedly connected between the limiting side plate 31 and the mounting top frame 9.

[0035] Reference Figure 2 and Figure 6 The supporting cross frame 33 is horizontally arranged between the two supporting inclined frames 32 and the two limiting side plates 31. Connecting rollers are arranged on the sides of the supporting cross frame 33 on both sides in the width direction. The side wall of the supporting inclined frame 32 close to the supporting cross frame 33 is provided with a connecting blind groove 321 along its width direction. The connecting roller is slidably arranged in the connecting blind groove 321 and is rolled and fitted with the inner bottom wall. The two ends of the supporting cross frame 33 in the length direction correspond to the two limiting side plates 31 one by one and are fitted. The adjusting slider 34 is fixedly connected to one end of the supporting cross frame 33 in the length direction. The limiting side plates 31 are provided with a connecting slide 311 corresponding to the position of the adjusting slider 34 in the vertical direction. The adjusting slider 34 is slidably arranged in the corresponding connecting slide 311. One end of the adjusting slider 34 passes through the limiting side plate 31 through the connecting slide 311. An adjusting screw 35 is vertically arranged on one side of the limiting side plate 31 away from the supporting cross frame 33, and a mounting plate 36 is rotatably connected to each end of the adjusting screw 35, and the mounting plate 36 is fixedly connected to the limiting side plate 31. The adjusting screw 35 is threadedly connected to the adjusting slider 34, and an adjusting handle 37 is connected to one end of the adjusting screw 35.

[0036] Reference Figure 1-3, the outer wall of the welding chamber 1 is connected with a vacuum tube 11 and a gas charging tube 12, a vacuum pump 13 is provided on the side of the vacuum tube 11 away from the welding chamber 1, an argon gas cylinder 14 is provided on the end of the gas charging tube 12 away from the welding chamber 1, a gas charging pump 15 is provided on the gas charging tube 12, and a balancing valve 16 for balancing the air pressure inside and outside the welding chamber 1 is provided on the welding chamber 1. A first control switch 17 is provided on the bottom surface of the support cross frame 33 above the soft film 2, and a second control switch 18 is provided on the top surface of the support cross frame 33 below the soft film 2. The first control switch 17 is electrically connected to the gas charging pump 15, and the second control switch 18 is electrically connected to the vacuum pump 13. An infrared gas sensor 19 for detecting the concentration of argon gas is connected to the inner wall of the welding chamber 1. A heating bottom plate 20 is fixedly connected to the bottom wall of the welding chamber 1, and a heating electric heating tube 21 is provided in the heating bottom plate 20. A cooling coil 22 is provided on one of the vertical inner walls of the welding chamber 1.

[0037] Reference Figure 2 and Figure 4 When welding a workpiece, open the box door 101 and place the workpiece in the welding chamber 1, cover the two sealing plates 4 on the connecting port 103, and fill the gap between the connecting port 103 and the sealing plate 4 with the sealing ring 8. Rotate the rotary limit plate. As the rotary limit plate rotates, the connecting plate 5 moves toward the welding chamber 1 under the push of the pressing slope 61, thereby improving the sealing degree between the sealing plate 4 and the welding chamber 1. The setting of the sealing plate 4 prevents the operating gloves 105 from being over-expanded and damaged by the air pressure during the vacuuming process. The setting of the extended sleeve 104 prevents the operating gloves 105 from expanding out of the welding groove in the opposite direction after inflation, which affects the normal welding operation of the operator.

[0038] Reference Figure 2 and Figure 3 , start the vacuum pump 13 to evacuate the interior of the welding chamber, and the soft film 2 is recessed toward the inner cavity of the welding chamber 1 under the action of air pressure. When the soft film 2 is recessed inward until it abuts against the second control switch 18, the vacuum pump 13 receives a signal and stops evacuating. After completing the vacuuming operation on the welding chamber 1, start the inflation pump 15, and fill the argon gas in the argon gas cylinder 14 into the welding chamber 1 through the inflation tube 12, and the soft film 2 gradually expands and bulges outward. When the soft film 2 expands outward until it abuts against the first control switch 17 located on the support frame 3 above the mounting top frame 9, the inflation pump 15 receives a signal and stops inflating. The degree of vacuuming and inflation of the welding chamber 1 can be intuitively observed by the degree of protrusion or depression of the soft film 2, and the setting of the soft film 2 also helps to carry out the inflation and deflation operations faster.

[0039] Reference Figure 2 and Figure 6The internal volume of the support frame 3 can be adjusted according to the different vacuum degrees and argon concentrations required for processing operations. By rotating the adjustment handle 37, the adjustment slider 34 moves in the vertical direction under the drive of the adjustment screw 35 and the limiting guide of the connecting slide 311. The connecting roller arranged on the support cross frame 33 slides in the connecting blind groove 321 in the supporting inclined frame 32, thereby realizing the adjustment of the internal volume of the support frame 3. The setting of the support frame 3 realizes the limitation of the deformation degree of the soft film 2, reduces the possibility of the soft film 2 bursting in the over-vacuumed or inflated state, and improves the safety of the operation process. The setting of the infrared gas sensor 19 realizes the real-time detection of the argon concentration inside the welding chamber 1.

[0040] Reference Figure 2 and Figure 5 When the soft film 2 is damaged or leaks, the upper clamp frame 91 is lifted up through the buckle 93, and the soft film 2 is removed and replaced through the airtight zipper 96. Two airtight rubber rings 97 clamp the two sides of the soft film 2 at the same time, thereby improving the airtightness of the welding chamber 1. While the welding chamber 1 is being evacuated, the heating electric heating tube 21 heats the inner cavity of the welding chamber 1, causing the air therein to expand and be drawn out of the welding chamber 1, which helps to increase the vacuum degree in the welding chamber 1 and reduce the possibility of oxidation during the welding process. After the vacuum is evacuated, the heating electric heating tube 21 stops heating, and the cooling medium is injected into the cooling coil 22 to cool the inner cavity of the welding chamber 1. On the one hand, this prevents the inside of the welding chamber 1 from overheating and causing injuries to the operator. On the other hand, the cooling environment helps more argon gas to enter the welding chamber 1, thereby improving the argon gas protection effect during the welding process. Combined with Figure 3 After welding is completed, the balance valve 16 is lifted to balance the air pressure inside and outside the welding chamber 1, and the soft film 2 is restored to a flat state, reducing the possibility of damage to the soft film 2 caused by being in a deformed state for a long time.

[0041] The implementation principle of a titanium alloy welding soft chamber in the embodiment of the present application is as follows: when welding a workpiece, open the chamber door 101 and place the workpiece in the welding chamber 1, and cover the two sealing plates 4 on the connecting port 103. Start the vacuum pump 13 to evacuate the welding chamber, and after the welding chamber 1 is evacuated, start the gas pump 15 to fill argon gas into the welding chamber 1. The degree of evacuation and gas filling of the welding chamber 1 is visually observed by the degree of convexity or concavity of the soft film 2.

[0042] The internal volume of the support frame 3 can be adjusted according to the different vacuum degrees and argon concentrations required for processing operations. The support frame 3 limits the deformation degree of the soft film 2, reducing the possibility of the soft film 2 bursting. While the welding chamber 1 is being evacuated, the heating electric heating tube 21 is heated to help improve the vacuum degree in the welding chamber 1. After the evacuation is completed, the cooling medium is injected into the cooling coil 22 to cool the inner cavity of the welding chamber 1, which helps more argon gas enter the welding chamber 1.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
