Description

Technical Field

[0001] This invention relates to the field of titanium welding and processing technology, and specifically to an integrated titanium welding equipment. Background Technology

[0002] Titanium and titanium alloys are widely used in aerospace, chemical, and medical fields due to their excellent specific strength, corrosion resistance, and high-temperature performance. Before welding, titanium materials typically require pretreatment processes such as surface cleaning and end chamfering to ensure the quality of the weld joint. However, existing integrated titanium welding equipment is mostly designed for regular titanium materials. For irregular titanium materials, the pretreatment and welding operations often require manual assistance or multiple machines to complete the process in stages, which is cumbersome, inefficient, and makes it difficult to guarantee consistent weld quality.

[0003] Furthermore, titanium materials have extremely high requirements for the welding environment. During the welding process, they easily react with elements such as oxygen, nitrogen, and hydrogen in the air, leading to defects such as weld embrittlement and porosity. Therefore, the welding process usually needs to be carried out under inert gas protection. Existing equipment mostly uses open gas shields or integral argon-filled chambers. The former has unstable protection effects, while the latter is bulky, consumes a large amount of gas, and is difficult to adapt to the welding requirements of titanium materials of different specifications. Summary of the Invention

[0004] In view of the above, it is necessary for the present invention to provide an integrated titanium welding equipment to solve the problems of separation of titanium welding pretreatment and welding process, poor adaptability and unstable welding quality in the prior art.

[0005] The technical solution of the present invention is as follows: An integrated titanium welding device includes a frame, a cleaning mechanism, a chamfering mechanism, and a welding mechanism. The frame has two parallel vertical cabinets spaced apart. The cleaning mechanism is located between the two vertical cabinets, and its two ends are fixedly connected to the middle position of the vertical cabinets. The chamfering mechanism is installed on the top of one end of the cleaning mechanism. The welding mechanism is fixed between the two vertical cabinets and located above the cleaning mechanism, and is on the same horizontal plane as the chamfering mechanism.

[0006] Furthermore, the cleaning mechanism includes a cleaning tank, two scrubbing rollers, two drying rollers, a translation component, and a lifting component. The cleaning tank is fixed to the bottom of two vertical cabinets and contains cleaning liquid. The two scrubbing rollers are mounted vertically on the feed end of the cleaning tank, and each scrubbing roller is connected to a liquid pump at its end. The suction end of the liquid pump extends below the surface of the cleaning liquid, and the discharge end communicates with the internal cavity of the scrubbing roller. The scrubbing roller wall is provided with seepage holes. The two drying rollers are arranged parallel to each other on the inner side of the two scrubbing rollers and are arranged vertically. The drying rollers are made of water-absorbing elastic material.

Two racks are symmetrically distributed on both sides of the double-layered gear sleeve in an upper and lower stacked manner, with the length direction of the racks aligned with the length direction of the movable cavity, and the two racks alternately mesh with the two layers of gear discs of the double-layered gear sleeve. The support beam is fixedly positioned directly below the beam frame, forming a gap between it and the beam frame for the titanium strip to pass through.

[0008] Furthermore, a guide plate protrudes downward from the bottom surface of the beam frame towards the titanium material conveying path. A guide strip is provided on the guide plate along the length of the moving cavity. One end of the guide strip has an inclined surface structure extending upward. An elastic pressure plate is fixedly provided above the inclined extension end. An isosceles trapezoidal guide block that cooperates with the guide strip is provided on the outer peripheral wall of the double-layer toothed sleeve.

[0009] Furthermore, a water cavity is also provided inside the beam frame, which is arranged parallel to the moving cavity. Several water nozzles are provided on the bottom surface of the water cavity along the length direction. Each water nozzle is equipped with a nozzle that can rotate around its own axis at its lower end. The nozzle has a turbine structure inside. A transmission belt is provided on the side of the nozzle near the double-layer toothed sleeve. One side of the transmission belt meshes with the double-layer toothed sleeve, and the other side meshes with the outer periphery of the nozzle. A scraper is fixedly provided on the side of the nozzle away from the transmission belt. The scraping end of the scraper is in contact with the titanium belt conveying surface.

[0010] Furthermore, the welding mechanism includes a welding cabinet, a welding torch, a sealing door, and a folding-down door; the welding cabinet is an arched cover structure with an opening at the bottom, and inlets and outlets are respectively opened on its two side walls along the titanium material conveying direction, with flexible sealing gaskets installed inside both inlets and outlets; inlet chambers and outlet chambers are respectively formed on the outer sides of the inlet and outlet, and both inlet and outlet chambers are connected to a gas separator through gas guide pipes, with a gas storage tank connected to the rear end of the gas separator through a gas guide pipe; the welding cabinet is located near the two vertical cabinets. An arc-shaped sliding groove is formed horizontally on the end face, and a long rod is supported between the two sliding grooves. The two ends of the long rod are slidably connected to the sliding grooves through sliding blocks. Longitudinal movement grooves are formed along the width of the titanium strip on the other two opposite inner sides of the welding cabinet. Drive motors are installed in the longitudinal movement grooves, and an arc rod is supported between the output ends of the two drive motors. An oscillation source is also fixedly installed inside the welding cabinet, and the free end of the oscillation source is movably connected to the long rod. The welding torch is set at the intersection of the long rod and the arc rod and can slide freely along the long rod and the arc rod.

[0011] Furthermore, the welding torch includes a base and a torch head; the base is provided with sliding channels that cooperate with the long rod and the arc rod; the torch head is connected to the lower end of the base through a lifting and rotating structure.

[0012] Furthermore, the sealing door is installed inside the welding cabinet, dividing the space inside the welding cabinet into upper and lower layers; the sealing door is a four-panel double-opening sliding door structure, of which two are fixed doors, fixed below the inlet and outlet; the other two are sliding doors, installed on the top surface of the fixed doors via sliding guide rails, and can slide horizontally along the length of the fixed doors; spray heads and heating wires are evenly installed on the bottom surface of the sliding doors facing the titanium pretreatment area; fasteners are fixedly installed on the top surface of the sliding doors away from the titanium pretreatment area.

[0013] Furthermore, the downward-folding door is designed as a double-leaf folding and opening door structure, hinged to the lower opening end of the welding cabinet; both doors of the downward-folding door are equipped with opening and closing motors; both doors are equipped with retractable sliding plates at their free ends, and the free ends of the sliding plates are equipped with positioning components for positioning and supporting irregular titanium materials.

[0014] Beneficial effects: 1.

This significantly improves production efficiency and can simultaneously adapt to the welding needs of both regular and irregular titanium strips, making it highly versatile.

[0015] 2. The cleaning mechanism adopts a combination of liquid washing, brushing, and drying, and is equipped with movable lifting components and clamps. It can perform online cleaning of continuous titanium strips and immersion cleaning of irregular titanium materials, which is thorough and adaptable.

[0016] 3. The chamfering mechanism uses the meshing transmission of a double-layer toothed sleeve and a rack to drive the chamfering drill bit to automatically feed and chamfer along the end of the titanium strip. With the lifting control of the guide bar, the chamfering process is automated. At the same time, the rotation of the chamfering drill bit drives the nozzle to rotate and spray water to cool and clean the chamfered area in real time, effectively preventing thermal deformation of the titanium material and improving the chamfering accuracy.

[0017] 4. The welding mechanism adopts a closed welding cabinet with a gas circulation system, which realizes high-purity argon gas protection welding and recovers argon gas through a gas separator, significantly reducing gas consumption costs; the welding torch can be adjusted in multiple dimensions to adapt to the welding position of titanium materials of different specifications; the combination design of the sealing door and the downward folding door not only ensures the sealing of the welding space, but also facilitates the loading and unloading of irregular titanium materials.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0021] like Figure 1 As shown, this invention provides an integrated titanium welding equipment suitable for welding both regular and irregular titanium strips. The equipment includes a frame 1, a cleaning mechanism 2, a chamfering mechanism 3, and a welding mechanism 4. The frame 1 has two parallel vertical cabinets 11 spaced apart. Transformers and other electrical components are installed inside the vertical cabinets 11 to provide a stable power supply to the electrical components of the cleaning mechanism 2, chamfering mechanism 3, and welding mechanism 4. The cleaning mechanism 2 is positioned between the two vertical cabinets 11, with both ends fixedly connected to the middle of each cabinet. The chamfering mechanism 3 is installed at the top of one end of the cleaning mechanism 2. The welding mechanism 4 is also fixed between the two vertical cabinets 11, located above the cleaning mechanism 2, and at the same horizontal level as the chamfering mechanism 3, ensuring smooth horizontal conveying of the titanium strip and achieving continuous connection between each process.

[0022] Combination Figure 2 , Figure 3 As shown, the cleaning mechanism 2 is located in the lower part of the frame 1 and is used to perform surface cleaning treatment on regular titanium strips and irregular titanium materials before welding. It removes impurities such as oil, dust, and metal shavings attached to the surface of the titanium materials to avoid impurities affecting the subsequent chamfering accuracy and welding joint quality. Specifically, it includes a cleaning tank 21, two brushing rollers 22, two drying rollers 23, a translation component 24, and a lifting component 25. All components work together to achieve liquid washing, brushing, and drying of the titanium materials, and can be adapted to the in-tank cleaning of irregular titanium materials.

[0023] The cleaning tank 21 is an open-top structure fixed to the bottom of two vertical cabinets 11. It can hold a special cleaning solution for titanium materials, providing a cleaning medium for cleaning titanium materials. Two brush rollers 22 are mounted vertically on the feed end of the cleaning tank 21. Each brush roller 22 is connected to a liquid pump at its end. The suction end of the liquid pump extends below the surface of the cleaning solution in the cleaning tank 21, and the discharge end is connected to the internal cavity of the brush roller 22. During operation, the liquid pump draws the cleaning solution from the cleaning tank 21 and delivers it to the inside of the brush roller 22. The cleaning solution seeps through the seepage holes on the wall of the brush roller 22 to the outer surface of the roller, achieving dual cleaning of liquid washing and brushing during the titanium material cleaning process, thus improving the overall cleaning effect.

[0024] Two drying rollers 23 are arranged parallel to each other on the inner side (discharge side) of two washing rollers 22, and the two drying rollers 23 are also arranged vertically. The roller body is made of a highly absorbent and wear-resistant elastic material. When processing the regular titanium strip, the titanium strip passes horizontally between the two washing rollers 22. After being washed and brushed by the washing rollers 22, it continues to enter horizontally between the two drying rollers 23. Through the squeezing and friction generated by the relative rotation of the two drying rollers 23, the cleaning liquid attached to the surface of the titanium strip is quickly removed, and the initial drying of the titanium strip is completed, providing a dry titanium surface for the subsequent chamfering process.

[0025] The translation component 24 is a linear moving mechanism, which is fixedly installed at the bottom of the cleaning tank 21. It can reciprocate linearly along the length of the cleaning tank 21, and the moving stroke covers the entire area of ​​the cleaning tank 21 from the inlet end to the outlet end. The lifting component 25 is a vertical lifting mechanism, which is fixed on the top of the translation component 24. The lifting end of the lifting component 25 is set upward, and a clamp (not shown) can be replaced on its top. The clamp can be adapted and replaced according to the shape and size of the irregular titanium material, and is used to clamp and support the irregular titanium material to achieve the fixed clamping of the irregular titanium material.

[0026] When cleaning irregular titanium materials, the titanium materials are clamped on the fixture at the top of the lifting component 25. The lifting component 25 drives the fixture and the titanium materials to descend vertically, completely immersing the titanium materials in the cleaning solution of the cleaning tank 21. The translation component 24 drives the lifting component 25 and the titanium materials to move linearly along the cleaning tank 21, so that the titanium materials are thoroughly cleaned in the cleaning solution. After cleaning, the translation component 24 drives the titanium materials to the discharge end of the cleaning tank 21. The lifting component 25 drives the titanium materials to rise vertically, so that the titanium materials are aligned with the welding operation area of ​​the welding mechanism 4, preparing for the subsequent welding process.

[0027] like Figure 3 , Figure 4 As shown, the chamfering mechanism 3 is clamped on the titanium material conveying path between the washing roller 22 and the drying roller 23, and is fixedly connected to the top of the feed end of the cleaning mechanism 2. It is used to perform precision chamfering on the joint end of the regular titanium strip, ensuring the end face fit when the two titanium strips are joined, and avoiding excessive joint gap or end face misalignment that affects the welding quality. Specifically, it includes a beam frame 31, a chamfering motor 32, a chamfering drill bit 33, two racks 34, and a supporting beam 35, which can realize stable support, auxiliary cleaning and centralized collection of waste chips and waste liquid when the titanium strip is chamfered.

[0028] The beam frame 31 is the overall support frame for the chamfering mechanism 3. A movable cavity 311 is provided inside the beam frame along the width direction of the titanium material. The chamfering motor 32 is slidably installed in the movable cavity 311 through a sliding seat and can move linearly back and forth along the movable cavity 311. A long slot is provided at the bottom of the movable cavity 311 along the length direction. The long slot is connected to the movable cavity 311 and allows the output rotation axis of the chamfering motor 32 to extend downward outside the movable cavity 311, providing space for the installation and operation of the chamfering drill bit 33.

[0029] The chamfering drill bit 33 is slidably connected to the output rotating shaft of the chamfering motor 32 along the axial direction via an axial sliding structure. The chamfering motor 32 drives the chamfering drill bit 33 to rotate at high speed to achieve chamfering of the titanium strip end. At the same time, the chamfering drill bit 33 can adjust its extension length through axial sliding to adapt to the processing requirements of different titanium strip thicknesses and different chamfering depths. The chamfering drill bit 33 is coaxially fitted with a double-layer toothed sleeve 331. The double-layer toothed sleeve 331 is connected to the output rotating shaft of the chamfering motor 32 through a reduction mechanism. The reduction mechanism can effectively reduce the rotation speed of the double-layer toothed sleeve 331, making the rotation speed of the double-layer toothed sleeve 331 lower than the rotation speed of the chamfering drill bit 33, thus meeting the different speed requirements of transmission and chamfering processing.

[0030] Two racks 34 are stacked vertically and symmetrically distributed on both sides of the double-layer toothed sleeve 331. The length direction of the two racks 34 is consistent with the length direction of the moving cavity 311, and the two racks 34 alternately mesh with the two layers of toothed discs of the double-layer toothed sleeve 331. When the chamfering motor 32 drives the double-layer toothed sleeve 331 to rotate, the double-layer toothed sleeve 331 generates a linear driving force along the length direction of the racks 34 through meshing with the racks 34 on both sides. This drives the chamfering motor 32 and the chamfering drill bit 33 to reciprocate linearly within the moving cavity 311, thereby realizing continuous chamfering operation at the end of the titanium strip.

[0031] Furthermore, a guide plate 312 protrudes downward from the bottom surface of the beam frame 31 towards the titanium material conveying path. A guide strip 313 is provided on the guide plate 312 along the length direction of the moving cavity 311. One end of the guide strip 313 has an inclined surface structure extending upward, and an elastic pressure plate 314 is fixedly provided above the inclined end. On the outer peripheral wall of the double-layer toothed sleeve 331, an isosceles trapezoidal guide block 3311 is integrally formed at the position that cooperates with the guide strip 313. The guide block 3311 cooperates with the inclined surface of the guide strip 313 and the pressure plate 314 to realize the lifting guidance and movement limit of the double-layer toothed sleeve 331 and the chamfering drill bit 33, ensuring the accuracy of the chamfering processing trajectory of the chamfering drill bit 33.

[0032] A water cavity 315 is also provided inside the beam frame 31, which is arranged parallel to the moving cavity 311. The water cavity 315 can store clean cooling water. Several water nozzles are evenly spaced along the length of the bottom surface of the water cavity 315. Each water nozzle has a nozzle 316 mounted at its lower end, which can rotate around its own axis. The nozzle 316 has a turbine structure inside. During operation, the turbine structure can increase the discharge pressure of the cooling water, enhancing the water spraying effect. The nozzle 316 is located near the double-layer toothed sleeve 331. A transmission belt is provided on the side. One side of the transmission belt meshes with the double-layer toothed sleeve 331 through a gear structure, and the other side meshes with the outer periphery of the nozzle 316. When the double-layer toothed sleeve 331 rotates, the nozzle 316 is driven to rotate through the synchronous transmission of the transmission belt. A scraper 317 is fixedly provided on the side of the nozzle 316 away from the transmission belt. The scraping end of the scraper 317 is in contact with the conveying surface of the titanium belt to initially scrape off the cleaning liquid remaining on the surface of the titanium belt and improve the cleaning effect of the cleaning cooling water on the surface of the titanium material.

[0033] The support beam 35 is fixedly installed directly below the beam frame 31, arranged vertically in correspondence with the beam frame 31. During the titanium strip chamfering process, the titanium strip passes horizontally through the gap between the beam frame 31 and the support beam 35. The support beam 35 provides stable lower support for the titanium strip, preventing it from bending or deforming due to stress during the chamfering process, thus ensuring the chamfering accuracy. A drainage groove 351 is provided on the top surface of the support beam 35 along the width direction of the titanium strip, and a nozzle 316 is also provided on the support beam 35. The drainage groove 351 can collect the cooling water sprayed by the nozzle 316 and the residual cleaning liquid on the surface of the titanium strip during the chamfering process, preventing the waste liquid from flowing back into the cleaning tank 21 and causing cleaning liquid contamination. A detachable filter screen can also be installed in the drainage groove 351. The filter screen can filter the metal waste generated during the titanium strip chamfering process, realizing the initial separation of waste waste and waste liquid, which facilitates the subsequent centralized treatment of waste waste and waste liquid.

[0034] When the shaped titanium strip enters the working area of ​​the chamfering mechanism 3 along the conveying path, the brush roller 22 of the cleaning mechanism 2 rotates synchronously to continuously wash and brush the surface of the titanium strip. The titanium strip passes horizontally through the gap between the beam frame 31 and the support beam 35. First, the cleaning liquid attached to the surface is initially scraped off by the scraper 317. Then, the nozzle 316 on the beam frame 31 rotates and sprays water under the drive of the double-layer toothed sleeve 331 to thoroughly rinse the cleaning liquid remaining on the surface of the titanium strip. The waste liquid after rinsing flows into the drainage trough 351 of the support beam 35 for centralized collection, while the waste is filtered and intercepted by the filter screen in the drainage trough 351.

[0035] The titanium strip that has completed surface cleaning continues to move toward the drying roller 23. At this time, the titanium strip has not completely passed through the drying roller 23, and its mating end is directly below the chamfering drill bit 33. Another titanium strip that has been cleaned by the cleaning mechanism 2 is then transported to the corresponding position, so that the mating ends of the two titanium strips are aligned and the alignment preparation before chamfering is completed.

[0036] The double-layer toothed sleeve 331, initially positioned above the guide bar 313, moves towards the oblique extension end of the guide bar 313 under the drive of the chamfering motor 32. When the guide block 3311 contacts the pressure plate 314, the free end of the pressure plate 314 fits against the isosceles trapezoidal inclined surface of the guide block 3311 and elastically deforms upward along the inclined surface. When the guide block 3311 moves to disengage from the oblique extension end of the guide bar 313, the pressure plate 314 resets under its own elasticity and pushes the guide block 3311 downward, causing the double-layer toothed sleeve 331 and the chamfered drill bit 33 to descend vertically below the guide bar 313.

[0037] Subsequently, under the meshing transmission of the double-layer gear sleeve 331 and the rack 34, the chamfering motor 32 and the chamfering drill bit 33 move linearly along the guide bar 313. At the same time, the chamfering drill bit 33 extends axially and reaches the joint ends of the two titanium strips to perform high-speed rotational chamfering. During the chamfering process, the cooling water in the water cavity 315 is continuously sprayed out through the nozzle 316 to cool the chamfering position in real time, reduce the heat generated by friction during the chamfering process, avoid thermal deformation of the titanium material due to high temperature, and ensure the processing accuracy of the titanium strip.

[0038] When the chamfering drill bit 33 moves to the discharge end of the guide bar 313, under the action of the guide structure, the chamfering drill bit 33 and the double-layer toothed sleeve 331 rise vertically to reset, move along the top of the guide bar 313 to the initial position, complete one chamfering operation of the titanium strip end, and wait for the next set of titanium strip chamfering operation instructions.

[0039] like Figure 5 , Figure 6 As shown, the welding mechanism 4 is fixedly installed above the cleaning mechanism 2 and is on the same horizontal plane as the chamfering mechanism 3. It is used to complete the welding operation of regular titanium strips and irregular titanium materials after cleaning and chamfering pretreatment. Specifically, it includes a welding cabinet 41, a welding torch 42, a sealing door 43, and a folding door 44. All components work together to create a sealed, high-purity argon gas protective environment for titanium welding, while realizing multi-dimensional adjustment of the welding torch position to ensure the welding quality of titanium materials.

[0040] The welding cabinet 41 is designed as an arched enclosure structure with an opening at the bottom, which provides a sealed welding space for titanium welding operations, effectively preventing external air from entering the welding area and avoiding chemical reactions between the titanium material and oxygen, nitrogen, etc. in the air during welding, which could lead to welding defects. On the two side walls of the welding cabinet 41, inlet and outlet are respectively opened along the titanium material conveying direction for the horizontal entry and exit of the shaped titanium strip. Flexible sealing gaskets are fixedly installed in both the inlet and outlet, and the flexible sealing gaskets are elastically fitted to the surface of the titanium strip to ensure the airtightness of the welding cabinet 41.

[0041] The inlet and outlet are respectively formed with an inlet chamber 411 and an outlet chamber 412. Both the inlet chamber 411 and the outlet chamber 412 are connected to the same gas separator through a gas guide pipe. The gas separator is fixedly installed at the top of the welding cabinet 41, and the rear end of the gas separator is connected to a gas storage tank through a gas guide pipe. The gas storage tank stores high-purity argon gas. During operation, the high-purity argon gas in the gas storage tank is introduced into the interior of the welding cabinet 41 through the pipe, and the air in the welding cabinet 41 is discharged, providing an inert gas protective atmosphere for titanium welding and improving the tightness and mechanical properties of the titanium weld joint.

[0042] Inside the welding cabinet 41, on the end faces near the two vertical cabinets 11, there are arc-shaped sliding grooves 413 in the horizontal direction. A long rod is installed between the two sliding grooves 413, and the two ends of the long rod are slidably connected to the two sliding grooves 413 through sliding blocks, which can move back and forth in an arc along the sliding grooves 413. On the other two opposite inner sides of the welding cabinet 41, there are longitudinal moving grooves 414 in the width direction of the titanium strip. The longitudinal moving grooves 414 are located above the feed inlet and the discharge outlet. A drive motor 415 is installed in each of the two longitudinal moving grooves 414. An arc rod is installed between the output ends of the two drive motors 415. The drive motors 415 drive the arc rod to move linearly back and forth in the longitudinal moving grooves 414.

[0043] An oscillating source is fixedly installed on the wall surface of the welding cabinet 41, where a sliding groove 413 is provided. The free end of the oscillating source is movably connected to a long rod, which can drive the long rod to oscillate back and forth in an arc along the sliding groove 413. The welding torch 42 is set at the intersection of the long rod and the arc rod, and can slide freely along the long rod and the arc rod. In conjunction with the arc movement of the long rod and the longitudinal movement of the arc rod, the welding torch 42 can be adjusted in multiple dimensions in terms of horizontal, longitudinal and angular dimensions within the welding cabinet 41, adapting to the welding needs of different specifications of titanium materials and different welding positions.

[0044] The welding torch 42 is a special welding torch body for titanium materials, which specifically includes a base 421 and a torch head 422. The base 421 has sliding channels that cooperate with the long rod and the arc rod. The base 421 is fitted at the intersection of the long rod and the arc rod through the sliding channels and can slide freely along the long rod and the arc rod to realize the position adjustment of the welding torch 42. The torch head 422 is connected to the lower end of the base 421 through a lifting and rotating structure, which can be raised and lowered and rotated around its own axis. It can realize precise fine adjustment of welding depth and welding angle to meet the diverse welding process requirements of titanium materials.

[0045] The sealing door 43 is installed inside the welding cabinet 41, dividing the internal space of the welding cabinet 41 into upper and lower layers horizontally. The upper layer is the argon gas storage and transportation area, and the lower layer is the titanium material pretreatment area. The sealing door 43 is a four-panel double-opening sliding door structure, of which two are fixed doors 431 and the other two are sliding doors 432. The two fixed doors 431 are fixed below the inlet and outlet of the welding cabinet 41, respectively, serving as basic space division and support. The two sliding doors 432 are installed on the top surface of the two fixed doors 431 through sliding guide rails, and can slide horizontally back and forth along the length of the fixed doors 431 to realize the opening and closing of the titanium material pretreatment area.

[0046] On the side of the sliding door 432 facing the titanium pretreatment area, spray heads 433 and heating wires 434 are evenly installed. The spray heads 433 are connected to a clean water source through pipes and can spray high-pressure clean water to rinse the titanium material entering the titanium pretreatment area, removing residual micro-impurities and cleaning fluid from the surface of the titanium material, and further improving the cleanliness of the titanium material surface. The heating wires 434 are electric heating elements that can generate uniform heat to quickly dry the titanium material after secondary cleaning and the moisture in the titanium pretreatment area, preventing moisture from affecting the welding quality of the titanium material.

[0047] On the top surface of the sliding door 432, away from the titanium pretreatment area, a fastener 435 is fixedly installed. The fastener 435 is an adjustable clamping structure that can clamp and limit the regular titanium strip entering the welding cabinet 41 from the feed port, so as to achieve precise positioning of the titanium strip before welding and ensure the docking accuracy and welding accuracy of the titanium strip.

[0048] The downward-folding door 44 is a double-leaf folding and opening door structure. Its hinge is installed at the lower opening end of the welding cabinet 41. It is mainly used to accommodate the welding and feeding of irregular titanium materials. At the same time, it cooperates with the sealing door 43 to form a sealed titanium material pretreatment space. Both doors of the downward-folding door 44 are equipped with opening and closing motors (not shown in the figure). The opening and closing motors provide power for the folding and opening of the doors, realizing the automatic opening and closing of the doors. Both doors are equipped with retractable sliding plates 441 at their free ends. The sliding plates 441 slide between the hinged end and the free end of the door. The free end of the sliding plates 441 is equipped with a positioning component. The positioning component is an adjustable abutment structure used to position and support the irregular titanium materials.

[0049] When the irregular titanium material is cleaned by the cleaning mechanism 2 and moved to the underside of the welding cabinet 41, the opening and closing motor drives the two doors of the downward folding door 44 to fold outwards and open. The lifting component 25 of the cleaning mechanism 2 drives the clamp and the irregular titanium material to rise vertically. Then, the sliding tray 441 extends outwards, and the two positioning components abut against the two side walls of the titanium material to accurately position and stably support it. After positioning, the opening and closing motor drives the two doors to rotate upwards and close. The sliding tray 441 gradually retracts inwards into the corresponding door, smoothly lifting the titanium material into the titanium material pretreatment area between the sealing door 43 and the downward folding door 44, completing the welding loading and positioning of the irregular titanium material.

[0050] The welding mechanism 4 of this invention can be adapted to the individual welding operations of regular titanium strips and irregular titanium materials, or the welding operations between the two. Its core workflow for welding various types of titanium materials includes three stages: cleaning and drying, argon filling and gas circulation, and precision welding, as detailed below: Cleaning and Drying: The titanium strip is cleaned, chamfered, and dried by the brush roller 22 before entering the welding position; the titanium material is cleaned by the cleaning tank 21 and then enters the titanium material pretreatment area between the sealing door 43 and the downward folding door 44. The spray head 433 on the bottom of the sliding door 432 sprays high-pressure cleaning water to clean the surface of the titanium material in all directions, removing residual micro-impurities and cleaning liquid; the wastewater generated by cleaning flows into the wastewater tanks pre-opened on the two doors of the downward folding door 44, and is quickly pumped out by the water pump inside the door to the external wastewater collection device for centralized treatment; after the wastewater is discharged, the heating wire 434 is energized to generate uniform heat, which thoroughly and quickly dries the moisture on the surface of the titanium material and in the titanium material pretreatment area, ensuring the dryness of the welding operation environment.

[0051] Argon filling and gas circulation: To quickly remove water vapor generated during the drying process, a vent is provided on the sliding door 432, and a one-way valve 436 is installed in the vent. The one-way valve 436 makes the titanium pretreatment area between the sealing door 43 and the downward folding door 44 form a one-way connection with the feeding chamber 411 and the discharging chamber 412 of the welding cabinet 41. Only the gas in the titanium pretreatment area is allowed to be discharged to the feeding chamber 411 and the discharging chamber 412, preventing the external air and the gas in the feeding chamber 411 and the discharging chamber 412 from flowing back to the titanium pretreatment area.

[0052] High-purity argon gas in the storage tank is introduced into the upper space of the welding cabinet 41 through a pipeline. Under the action of air pressure, it continuously enters the titanium pretreatment area through the one-way valve 436, gradually discharging harmful gases such as water vapor and residual air in the area to the feed chamber 411 and the discharge chamber 412. Subsequently, the mixed gas enters the gas separator through the gas guide pipe. The gas separator separates the mixed gas, separating out the high-purity argon gas, which is then sent back to the storage tank through the gas guide pipe for storage, realizing the recycling of argon gas and effectively reducing the consumable cost of titanium welding.

[0053] Precision welding: When the titanium material pretreatment area is filled with high-purity argon gas and the titanium material has been positioned and dried, the sliding door 432 slides open; then the oscillating source drives the long rod to move in an arc along the sliding groove 413, and the drive motor 415 drives the arc rod to move longitudinally along the longitudinal groove 414. With the free sliding of the base 421 of the welding torch 42 along the long rod and the arc rod, as well as the lifting and rotation of the torch head 422, the welding end of the welding torch 42 is adjusted to the welding butt joint position of the titanium material, and adjusted to the optimal welding angle and welding depth; then the welding torch 42 is started to perform precision welding on the titanium material. It is worth mentioning that the weld joint depth of the titanium material is relatively large, and multiple layers of welding are required, so there is no need to perform chamfering treatment.

[0054] After the titanium material welding is completed, the sliding door 432 closes, and the two doors of the downward folding door 44 fold outwards and open, causing the titanium material to descend onto the clamp of the lifting component 25. The translation component 24 drives the clamp and the welded titanium material to move horizontally to the discharge end, completing the welding and unloading of irregular titanium materials. After the welding of the regular titanium strip is completed, it is directly conveyed to the outside of the equipment along the discharge port, completing the overall welding operation.

[0055] In summary, the integrated titanium welding equipment provided by this invention, through the integrated design of frame 1, cleaning mechanism 2, chamfering mechanism 3, and welding mechanism 4, realizes continuous and automated processing of titanium materials from pre-welding cleaning and chamfering pretreatment to welding operations, effectively improving the welding processing efficiency of titanium materials; at the same time, through designs such as real-time cooling of cleaning and chamfering, high-purity argon gas protection, and argon gas recycling, the welding processing accuracy and weld joint quality of titanium materials are guaranteed from multiple dimensions and in all aspects.
