Description

Technical Field

[0001] The present invention relates to the technical field of aluminum part processing, and more specifically, it relates to a cold welding processing device for aluminum part production. Background Art

[0002] Due to characteristics such as light weight, high strength, good thermal conductivity and corrosion resistance, aluminum parts are widely used in industry and daily life. Aluminum is easy to process and can be made into parts of various shapes and sizes through various processes such as casting, forging, extrusion, and rolling. In addition, aluminum has good welding performance. Cold welding of aluminum parts is a special welding technology that mainly realizes welding at a lower temperature through mechanical pressure and chemical reactions, avoiding problems such as deformation, cracks and oxidation caused by traditional high-temperature welding.

[0003] At present, the cold welding technology for aluminum parts on the market is mainly applicable to the welding of aluminum thin plates within 2 mm. Usually, it is divided into direct welding and welding with filler wire according to the gap between aluminum plates. Although this welding method can realize the connection of aluminum thin plates, due to the thin thickness and high thermal conductivity of aluminum plates, it is easy to deform and crack during cold welding. Automatic welding usually starts from the gap. When welding two groups of aluminum plates, it can be welded from the starting end to the end. However, when it comes to welding three groups of aluminum plates, there are not only weld seams but also weld beads. If the same method is used to weld from the starting end of the weld seam to the end, there will be accumulation at the weld bead. If there is a certain gap left at the weld bead and concentrated welding is carried out, first, there will be a problem of insecure welding. Second, since the gap at the weld bead is slightly wider, filler rods may be needed and there will still be an accumulation problem, resulting in a decline in the quality of aluminum parts.

[0004] In practical applications, the cold welding of aluminum thin plates faces many challenges. First, the high thermal conductivity of aluminum causes the heat to spread rapidly during welding, resulting in uneven temperature in the welding area and prone to deformation and cracks. Second, the thickness of the aluminum thin plate limits the selection of welding parameters. Too high current or voltage may cause the thin plate to melt or burn through, while too low parameters cannot form an effective weld seam. In addition, when welding three groups of aluminum plates, the treatment of the weld bead is particularly complex. Traditional welding methods are difficult to achieve uniform welding at the weld bead, and it is easy to have problems such as accumulation and lack of fusion, seriously affecting the welding quality. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a cold welding processing device for aluminum part production.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A cold welding processing device for aluminum part production, including a base, and the base includes a base plate arranged in the horizontal direction and a bracket arranged in the vertical direction;

[0008] A transmission unit, the transmission unit is arranged in the same direction on the top of the base. The transmission unit includes a slide rail arranged in the same direction as the base and a slide table slidably connected to the slide rail. A plurality of groups of mounting brackets are installed on the top of the slide table, and aluminum parts are placed on each group of mounting brackets.

[0009] Among them, the aluminum part is composed of three groups of aluminum thin plates. The three groups of aluminum thin plates are arranged perpendicular to each other in pairs. Two of the three groups of aluminum thin plates form a weld seam in pairs, and the three groups of aluminum thin plates together form a weld corner. According to the position, the weld seam in the horizontal direction is set as the Z-axis weld seam, and the two weld seams perpendicular to the horizontal direction are set as the X-axis weld seam and the Y-axis weld seam.

[0010] A processing unit, the processing unit is slidably connected to the bracket. The processing unit includes a processing frame slidably connected to the bracket. A preheating component is arranged on the processing frame, three welding components are arranged on the processing frame, and a control board is arranged on the processing frame.

[0011] Among them, the three welding components are respectively arranged on the top surface and two side surfaces of the aluminum part.

[0012] By adopting the above technical solutions, the aluminum part is placed on the mounting bracket. The sliding of the slide table on the slide rail drives the mounting bracket to slide, and the sliding of the mounting bracket drives the aluminum part to slide, so that the aluminum part passes through the processing unit slowly and uniformly. When the aluminum part slowly passes through the processing unit, the welding component can adjust the angle and azimuth, and weld the weld seam and weld corner on the aluminum part, thereby completing the welding process of the aluminum part, ensuring that the three aluminum thin plates of the aluminum part are mutually adhered and do not fall off during use, and ensuring the product quality of the aluminum part.

[0013] The present invention is further configured as: the welding component includes a welding main body connected to the processing frame. One end of the welding main body is connected with a driving module. A rotating shaft is installed at the end of the welding main body away from the driving module. A telescopic module is installed on the rotating shaft. One end of the telescopic module away from the rotating shaft is connected with a welding module.

[0014] The present invention is further configured as: the welding module includes a rotating buckle connected to the telescopic module. The rotating buckle is rotatably connected with a rotating main body. A connecting rod is connected to the rotating main body. A mounting rod is connected to the bottom of the connecting rod. A welding torch is installed on the mounting rod.

[0015] The present invention is further configured as: the control board is built-in with a control system. The control board is electrically connected to the transmission unit and the processing unit. The control of the transmission unit and the processing unit is realized through the control board.

[0016] Among them, the control board controls the sliding speed of the transmission unit, and the control board controls the movement, welding current, welding voltage and welding pressure of the processing unit.

[0017] The present invention is further configured such that the control board includes:

[0018] An information unit, the information unit includes a display screen and several groups of buttons, the information unit is used to receive welding information, and the information unit outputs the welding information;

[0019] A processing unit, the processing unit receives the welding information transmitted by the information unit, the processing unit analyzes the welding information, and analyzes the welding information into a welding data group and outputs the welding data group;

[0020] A control unit, the control unit receives the welding data group transmitted by the processing unit, and sends instructions to the transmission unit and the processing unit according to the data in the welding data group;

[0021] Among them, the welding data group includes the diameter of fish-scale patterns and the straight welding length.

[0022] The present invention is further configured such that: the welding information includes the X-axis welding length, the Y-axis welding length, the Z-axis welding length, the welding frequency, and the welding current.

[0023] The present invention is further configured such that: the processing unit processes according to the X-axis welding length, the Y-axis welding length, the Z-axis welding length, the welding frequency, and the welding current, and tests the diameter of fish-scale patterns according to the welding frequency and the welding current;

[0024] The processing unit calculates the X-axis straight welding length, the Y-axis straight welding length, and the Z-axis straight welding length according to the diameter of fish-scale patterns and the data of the X-axis welding length, the Y-axis welding length, and the Z-axis welding length.

[0025] By adopting the above technical solution, the processing unit processes according to the X-axis welding length, the Y-axis welding length, the Z-axis welding length, the welding frequency, and the welding current, and tests the diameter of fish-scale patterns according to the welding frequency and the welding current through welding tests; due to the characteristics of aluminum thin plates with different thicknesses and the requirements for welding, the diameter of fish-scale patterns cannot be accurately obtained by calculation, and the diameter of fish-scale patterns can be accurately obtained through tests. This step can not only obtain the diameter of fish-scale patterns, but also ensure the subsequent welding effect through the welding test process.

[0026] The present invention is further configured such that: the X-axis straight welding length, the Y-axis straight welding length, and the Z-axis straight welding length are equal to the X-axis welding length, the Y-axis welding length, and the Z-axis welding length minus the diameter of fish-scale patterns respectively.

[0027] The present invention is further configured such that the specific steps for the control unit to control the transmission unit and the processing unit include:

[0028] S1. The control unit controls the slide table to slide at a constant speed, and at the same time, the preheating component preheats the aluminum parts. The speed ensures the welding of the weld on the Z-axis, and at the same time, the welding component on the top of the aluminum parts performs welding.

[0029] S2. When the welding distance of the Z-axis weld is equal to the straight welding length of the Z-axis, stop welding.

[0030] S3. The control unit controls the welding components on both sides of the aluminum parts to perform welding. When the welding distances of the welding components on both sides are the same as the straight welding lengths of the X-axis and the Y-axis, stop welding.

[0031] S4. The three groups of welding components perform rotary welding.

[0032] The present invention is further configured that in S4, the three groups of welding components perform rotary welding. The specific method is as follows: Each group of welding components simultaneously performs rotary welding by rotating 120 degrees clockwise, and its fish-scale pattern forms a circle with the center of the weld bead.

[0033] By adopting the above technical solution, the present invention adopts rotary welding at the weld bead. If direct welding is used instead of the rotary welding in S4, that is, welding from the starting end to the ending end of the weld, since there will be repeated welding paths at the weld bead, accumulation will occur at the weld bead. And the accumulation will cause the weld bead to be too thick, and there may also be problems such as insecure welding caused by the accumulation, resulting in too low quality of the aluminum parts. If direct centralized welding is performed on the weld bead, there will also be problems such as difficult to accurately position the weld bead due to the limited processing position of the weld bead, and even if the position of the weld bead is accurately positioned and processed, there may be a possibility that the processing of the weld bead may damage the previous processing of the weld due to the special shape of the weld bead. By using rotary welding, the welding components simultaneously perform rotary welding by rotating 120 degrees clockwise, and its fish-scale pattern forms a circle with the center of the weld bead, so as to complete the firm welding of the weld bead, and no accumulation will occur at the weld bead part.

[0034] In summary, the present application includes at least one of the following beneficial technical effects:

[0035] 1. The aluminum parts are placed on the mounting rack. The sliding of the slide table on the slide rail drives the mounting rack to slide, and the sliding of the mounting rack drives the aluminum parts to slide, so that the aluminum parts slowly pass through the processing unit at a constant speed. When the aluminum parts slowly pass through the processing unit, the welding components can perform angle adjustment and azimuth adjustment to weld the welds and weld beads on the aluminum parts, thereby completing the welding process of the aluminum parts, ensuring that the three aluminum thin plates of the aluminum parts fit together without falling off during use, and ensuring the product quality of the aluminum parts.

[0036] 2. The processing unit processes according to the welding lengths in the X-axis, Y-axis, and Z-axis, welding frequency, and welding current, and tests the diameter of the fish scale pattern through a trial welding based on the welding frequency and welding current. Due to the characteristics of aluminum sheets with different thicknesses and the requirements for welding, the diameter of the fish scale pattern cannot be accurately obtained through calculation. Through experiments, the diameter of the fish scale pattern can be accurately obtained. This step can not only obtain the diameter of the fish scale pattern but also ensure the subsequent welding effect through the trial welding process.

[0037] 3. The present invention uses rotary welding at the weld corner. If direct welding is used instead of the rotary welding in S4, that is, welding from the starting end to the ending end of the weld seam, since there will be repeated welding paths at the weld corner, accumulation will occur at the weld corner. This accumulation will cause the weld corner to be too thick and may also lead to insecure welding due to the accumulation, resulting in low quality of the aluminum parts. If direct concentrated welding is performed on the weld corner, there will also be problems such as difficulty in accurately positioning the weld corner due to the limited machining position of the weld corner. And even if the weld corner position is accurately positioned and machined, there is a possibility that the machining of the weld corner may damage the previous machining of the weld seam due to the special shape of the weld corner. By using rotary welding and making the welding assembly rotate 120 degrees clockwise simultaneously, the fish scale pattern forms a circle centered on the weld corner, thus completing the firm welding of the weld corner and no accumulation will occur at the weld corner part.

[0047] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0048] It should be pointed out that unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0049] Please refer to Figures 1-5 , the present invention provides the following technical solutions:

[0050] Embodiment 1, a cold welding processing device for the production of aluminum parts, includes a base 1, a transmission unit 2, and a processing unit 3. The base 1 is used to provide an installation environment for the entire device to ensure the stable operation of the overall device; the transmission unit 2 is used to transport the aluminum parts 4 to ensure the smooth transportation of the aluminum parts 4 and avoid jitter and slipping of the aluminum parts 4 during transportation; the processing unit 3 is used to perform welding treatment on the welds and weld corners 41 of the aluminum parts 4 to ensure the firm welding of the three aluminum sheets of the aluminum parts 4.

[0051] The base 1 includes a base 11 arranged in the horizontal direction and a bracket 12 arranged in the vertical direction. The base 11 provides an installation environment for the transmission unit 2, and the bracket 12 provides an installation environment for the processing unit 3.

[0052] Refer to Figure 1 , the transmission unit 2 is arranged on the top of the base 11 in the same direction. The transmission unit 2 includes a slide rail 21 arranged in the same direction as the base 11 and a slide table 22 slidably connected to the slide rail 21. A plurality of groups of mounting frames 23 are installed on the top of the slide table 22, and the aluminum parts 4 are placed on each group of mounting frames 23.

[0053] Specifically, the slide table 22 can slide horizontally relative to the slide rail 21. By the horizontal sliding of the slide table 22 on the slide rail 21, the mounting frame 23 above it can be driven to slide horizontally. By the sliding of the mounting frame 23, the aluminum parts 4 can be driven to move horizontally. Subsequently, the aluminum parts 4 slide through the bottom of the processing unit 3, and the welding process of the aluminum parts 4 can be carried out linearly.

[0054] Refer to Figure 4 , the aluminum part 4 is composed of three groups of aluminum sheets. The three groups of aluminum sheets are arranged perpendicular to each other in pairs. Two of the three groups of aluminum sheets form a weld seam in pairs, and the three groups of aluminum sheets together form a weld corner 41. According to the position, the weld seam in the horizontal direction is set as the Z-axis weld seam, and the two weld seams perpendicular to the horizontal direction are set as the X-axis weld seam and the Y-axis weld seam.

[0055] Refer to Figures 1-3 , the processing unit 3 is slidably connected to the bracket 12. The whole processing unit 3 can move vertically relative to the bracket 12. The processing unit 3 includes a processing frame 33 slidably connected to the bracket 12. The processing frame 33 can slide vertically on the bracket 12. By the sliding of the processing frame 33, the whole processing unit 3 is driven to slide on the bracket 12. A preheating component 32 is arranged on the processing frame 33. The preheating component 32 includes heating wires. The preheating component 32 can preheat the aluminum part 4 when it passes by, avoiding deformation and fracture caused by too large a temperature difference due to the high thermal conductivity of the aluminum part 4. Three welding components 31 are arranged on the processing frame 33. The three welding components 31 are respectively arranged on the top surface and two side surfaces of the aluminum part 4, and can weld the weld seams and the weld corner 41 of the aluminum part 4. A control board 34 is arranged on the processing frame 33.

[0056] Refer to Figure 2 , the welding component 31 includes a welding main body 311 connected to the processing frame 33. One end of the welding main body 311 is connected with a driving module 312. A rotating shaft 313 is installed at the end of the welding main body 311 far from the driving module 312. The rotating shaft 313 can rotate 360 degrees. A telescopic module 314 is installed on the rotating shaft 313. The telescopic module 314 can telescope. One end of the telescopic module 314 far from the rotating shaft 313 is connected with a welding module 315.

[0057] Specifically, the driving module 312 can drive the welding component 31 to perform welding. The rotating shaft 313 can rotate. By the rotation of the rotating shaft 313, the telescopic module 314 and the welding module 315 can be driven to rotate. The telescopic module 314 can telescope. By the telescoping of the telescopic module 314, the movement of the welding module 315 can be driven, so that the welding module 315 can weld aluminum parts 4 of different specifications.

[0058] Refer to Figure 3, the welding module 315 includes a rotating buckle 3152 connected to the telescopic module 314, and the rotating buckle 3152 is rotatably connected to a rotating body 3151. The rotating buckle 3152 and the rotating body 3151 cooperate to enable omnidirectional rotation, so that the welding module 315 can perform welding from different angles and orientations. A connecting rod 3153 is connected to the rotating body 3151, the bottom of the connecting rod 3153 is connected to a mounting rod 3154, and a welding torch 3155 is mounted on the mounting rod 3154. The connecting rod 3153 and the mounting rod 3154 cooperate to enable the welding torch 3155 to perform welding at a certain angle.

[0059] Specifically, the aluminum part 4 is placed on the mounting rack 23. The sliding of the sliding table 22 on the slide rail 21 drives the mounting rack 23 to slide, and the sliding of the mounting rack 23 drives the aluminum part 4 to slide, so that the aluminum part 4 slowly and uniformly passes through the processing unit 3. When the aluminum part 4 slowly passes through the processing unit 3, the welding assembly 31 can perform angle adjustment and orientation adjustment to weld the weld seam and welding corner 41 on the aluminum part 4, thereby completing the welding process of the aluminum part 4.

[0060] Embodiment 2, please refer to Figures 1-5 , this Embodiment 2 makes the following improvements on the basis of Embodiment 1. Although the processing of the aluminum part 4 can be achieved through Embodiment 1, in the actual processing process, automatic welding usually starts from the gap. When welding two groups of aluminum plates, it can be welded from the starting end to the end, but when it comes to welding three groups of aluminum plates, there are not only weld seams but also welding corners 41. If the same method is used to weld from the starting end to the end of the weld seam, there will be accumulation at the welding corner 41; if there is a certain gap left at the welding corner 41 and concentrated welding is performed, there will be a problem of insecure welding. Therefore, a control board 34 is designed at the processing unit 3, and the processing method is precisely controlled through the built-in program of the control board 34.

[0061] In this embodiment, specifically: the control board 34 has a built-in control system, and the control board 34 is electrically connected to the transmission unit 2 and the processing unit 3, and the control of the transmission unit 2 and the processing unit 3 is realized through the control board 34; among them, the control board 34 controls the sliding speed of the transmission unit 2, and the control board 34 controls the movement, welding current, welding voltage and welding pressure of the processing unit 3.

[0062] In this embodiment, specifically, the control board 34 includes:

[0063] An information unit, the information unit includes a display screen and several groups of buttons. The information unit is used to receive welding information and output the welding information; the operator can input the required welding length of the aluminum part into the information unit.

[0064] The processing unit receives the welding information transmitted by the information unit, analyzes the welding information, and analyzes the welding information into a welding data group, and outputs the welding data group;

[0065] The control unit receives the welding data group transmitted by the processing unit and sends instructions to the transmission unit 2 and the processing unit 3 according to the data in the welding data group; wherein, the welding data group includes the diameter of the fish scale pattern and the straight welding length.

[0066] In this embodiment, specifically: the welding information includes the welding length in the X-axis, the welding length in the Y-axis, the welding length in the Z-axis, the welding frequency, and the welding current. Generally, the diameter of the fish scale pattern is related to the welding frequency and the welding current. The magnitude of the welding current directly affects the temperature and melting depth of the welding molten pool. The larger the current, the deeper the molten pool, and the diameter of the fish scale pattern will also increase accordingly. The welding frequency determines the residence time and cooling rate of the welding molten pool. The faster the welding speed, the shorter the residence time of the molten pool, and the diameter of the fish scale pattern will decrease.

[0067] The processing unit processes according to the welding length in the X-axis, the welding length in the Y-axis, the welding length in the Z-axis, the welding frequency, and the welding current, and tests the diameter of the fish scale pattern through a trial welding according to the welding frequency and the welding current; due to the characteristics of aluminum sheets with different thicknesses and the welding requirements, the diameter of the fish scale pattern cannot be accurately obtained by calculation, and in this embodiment, the diameter of the fish scale pattern can be accurately obtained through a single trial welding. This step can not only obtain the diameter of the fish scale pattern, but also ensure the subsequent welding effect through the trial welding process.

[0068] The processing unit calculates the straight welding length in the X-axis, the straight welding length in the Y-axis, and the straight welding length in the Z-axis according to the diameter of the fish scale pattern and the data of the welding length in the X-axis, the welding length in the Y-axis, and the welding length in the Z-axis. The straight welding length in the X-axis, the straight welding length in the Y-axis, and the straight welding length in the Z-axis are equal to the welding length in the X-axis, the welding length in the Y-axis, and the welding length in the Z-axis minus the diameter of the fish scale pattern respectively.

[0069] Specifically, in the actual welding process, the calculation method of the straight welding length in the X-axis, the straight welding length in the Y-axis, and the straight welding length in the Z-axis can be further adjusted according to the welding strength required by the weld bead 41. Correspondingly, the welding method can also be further adjusted. For example, for a higher requirement for the strength of the weld bead 41, two rotational weldings can be adopted, that is, through two clockwise rotations. After the first rotational welding, the aluminum part 4 is transported forward by the distance of the diameter of the fish scale pattern, and then another rotational welding is performed. At this time, the calculation method will be replaced by that the straight welding length in the X-axis, the straight welding length in the Y-axis, and the straight welding length in the Z-axis are equal to the welding length in the X-axis, the welding length in the Y-axis, and the welding length in the Z-axis minus twice the diameter of the fish scale pattern respectively.

[0070] In this embodiment, specifically, the specific steps for the control unit to control the transmission unit 2 and the processing unit 3 are as follows:

[0071] S1. The control unit controls the slide table 22 to slide at a constant speed. At the same time, the preheating component 32 preheats the aluminum workpiece 4, and its speed ensures the welding of the weld on the Z-axis. At the same time, the welding component 31 at the top of the aluminum workpiece 4 performs welding.

[0072] S2. When the distance welded by the welding component 31 on the Z-axis weld is equal to the straight welding length of the Z-axis, stop welding.

[0073] S3. The control unit controls the welding components 31 on both sides of the aluminum workpiece 4 to perform welding. When the welding distances of the welding components 31 on both sides to the weld are the same as the straight welding lengths of the X-axis and the Y-axis, stop welding.

[0074] S4. The three groups of welding components 31 perform rotary welding.

[0075] If instead of using the rotary welding in S4, direct welding is used, and welding is performed from the starting end to the ending end of the weld, since there will be repeated welding paths at the weld corner 41, stacking will occur at the weld corner 41. The stacking will cause the weld corner 41 to be too thick, and there may also be problems such as insecure welding due to stacking, resulting in too low quality of the aluminum workpiece 4. If direct centralized welding is performed on the weld corner 41, there will also be problems such as difficulty in accurately positioning the weld corner 41 due to the limited processing position of the weld corner 41. And even if the position of the weld corner 41 is accurately positioned and processed, there may be a possibility that the processing of the weld corner 41 may damage the previous processing of the weld due to the special shape of the weld corner 41.

[0076] Specifically, refer to Figure 5 , in S4, the three groups of welding components 31 perform rotary welding, and the specific method is: each group of welding components 31 simultaneously performs rotary welding at 120 degrees clockwise, and its fish-scale pattern forms a circle with the center of the weld corner 41, so as to complete the firm welding of the weld corner 41, and there will be no stacking at the weld corner 41 part.

[0077] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
