Description

Technical Field

[0001] This invention relates to the field of workpiece processing, specifically a welding system and low-temperature welding method for cast steel parts and steel components. Background Technology

[0002] Low-temperature welding, which involves welding at a lower temperature, reduces thermal deformation and deterioration of materials, ensuring product quality. It also reduces thermal stress and cooling shrinkage of welding materials, making them less prone to deformation and avoiding problems such as weak welds and product deformation.

[0003] Low-temperature heating involves preheating the workpiece before welding to reduce welding time and prevent workpiece deformation.

[0004] After preheating, welding needs to be performed quickly. To avoid discomfort caused to workers by the high temperature of preheating, a welding device is needed. Please refer to a rapid welding device, announcement number CN208496181U. This rapid welding device uses a cylinder to clamp and place the workpiece, saving manual labor and increasing production efficiency. Currently, most welded materials are placed manually, but the high temperature makes quick placement difficult. This invention uses a clamp to hold the welded material, with a feeding table below. A telescopic rod retracts, suspending the material at the bottom. The clamp then opens, and the material is conveyed to the next workstation via a conveyor belt, significantly saving time and allowing for rapid processing of the next item, thus improving production efficiency.

[0005] However, this device cannot be used in low-temperature welding that requires coaxial welding, for the following reasons:

[0006] 1. Because low-temperature welding requires preheating and does not heat the workpiece to its melting point, the welding work needs to be completed quickly after heating; otherwise, the heating temperature will drop rapidly, resulting in unsatisfactory welding results.

[0007] Second, due to concentric welding, it is necessary to quickly complete concentric positioning and placement of the auxiliary workpiece after heating;

[0008] The device cannot fulfill either of the two necessary conditions mentioned above. Summary of the Invention

[0050] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0052] Example 1, please refer to Figures 1 to 12 A welding system for cast steel parts and steel components includes a processing box 1. The processing box 1 has an integrally formed partition plate installed inside it, which divides the processing box 1 into a welding chamber and a preheating chamber. The partition plate has a slot that connects the preheating chamber and the welding chamber. The bottom of the processing box 1 is fixed with multiple support legs, which are not shown in the figure.

[0053] A lifting plate 10 is slidably mounted in the welding cavity via a sliding optical axis. A positioning component is mounted on the lifting plate 10. The positioning component cooperates with a pushing component mounted in the preheating cavity. A welding component is mounted above the lifting plate 10 in the welding cavity. A feeding component for placing the required welding parts is installed between the welding component and the lifting plate 10.

[0054] In this embodiment of the invention, for ease of description, the required preheating component is named the main workpiece, and the welded component is named the auxiliary workpiece, wherein the auxiliary workpiece is located within the feeding assembly;

[0055] The main workpieces are pushed into the preheating chamber by the feeding component 6 installed on one side of the processing box 1 and connected to the preheating chamber. The heating device set in the preheating chamber heats the part of the main workpiece to be welded. After the heating is completed, the main workpiece is pushed into the welding chamber through the slot by the pushing component. The main workpiece is positioned by the positioning component so that the main workpiece is in the designated position. Then the pushing and lifting device lifts the lifting plate 10. After the main workpiece rises to the end of the stroke, the auxiliary workpiece is placed on the main workpiece by the feeding component and is in a concentric state. Then, the two are welded together by the welding component.

[0056] In this embodiment, the lifting component uses a pushing device such as a cylinder or an electric telescopic rod. (Not shown in the figure.)

[0057] The pushing assembly includes a pushing member 3 that is slidably installed in the preheating chamber, and an electric telescopic rod 2 is fixed to the top of the processing box 1. The movable rod of the electric telescopic rod 2 is fixed to the pushing member 3.

[0058] A positioning block 13 is fixed inside the preheating cavity, and a reset component that cooperates with the positioning block 13 is also installed inside the preheating cavity.

[0059] In this embodiment of the invention, when the main workpiece is placed in the preheating chamber by the feeding component 6, the feeding component 6 and the limiting block 14 limit the main workpiece to its approximate position when it moves into the preheating chamber. Then, the resetting component positions the main workpiece in this position, so that the main workpiece is in the heating position of the heating device. Then, the heating component heats the main workpiece, so that the temperature of the required welding local position of the main workpiece rises. Then, the electric telescopic rod 2 is activated. When the electric telescopic rod 2 is working, the moving rod drives the pushing component 3 to move horizontally. The movement of the pushing component 3 pushes the welding main workpiece into the welding chamber and onto the positioning component.

[0060] The reset component includes a feeding port 15 disposed in the welding cavity. Two guide rods 7 are fixed to the top of the feeding port 15. Both guide rods 7 pass through the processing box 1 and are slidably connected to the processing box 1. Springs 9 are sleeved on both guide rods 7. A limiting block 14 fixed to the guide rods 7 is also installed in the preheating cavity.

[0061] The limiting block 14 has an arc-shaped surface facing the positioning block 13, and a rack 4 is fixed on one side of the limiting block 14. The rack 4 meshes with a gear plate 5 rotatably mounted on the outer wall of the processing box 1. The rack 4 is connected to the limiting block 14 through a connecting block. The processing box 1 has a movable groove for the connecting block to slide.

[0062] In this embodiment of the invention, after the main welding component moves into the preheating chamber, a slight positional deviation may occur, resulting in a deviation in the heating position. At this time, the gear disk 5 is driven to rotate by an external force / driving device.

[0063] When the gear disk 5 rotates, it drives the rack 4 to descend vertically, and then drives the limit block 14 to descend vertically through the connecting block. When the limit block 14 descends, it corrects the position of the biased main workpiece through the arc-shaped surface to ensure the accurate heating position.

[0064] When the limiting block 14 is vertically lowered, the spring 9 is compressed by the guide rod 7, so that the spring 9 stores a certain elastic potential energy. When the force driving the toothed disc 5 to rotate is small, the elastic potential stored in the spring 9 is released to drive the guide rod 7 and the limiting block 14 to reset.

[0065] The welding assembly includes a support arm 16 rotatably mounted in the welding cavity. A welding device 17 is adjustablely mounted at the end of the support arm 16. A first gear 20 is coaxially fixed on the rotating shaft of the support arm 16. A feeding port 15 is fixed on the processing box 1. The output shaft of the feeding port 15 is coaxially fixed with the rotating shaft of the support arm 16. The first gear 20 is connected to the feeding assembly.

[0066] In this embodiment of the invention, when the feed port 15 is working, the output shaft drives the support arm 16 to rotate. When the support arm 16 rotates, the welding equipment 17 welds the sub-workpiece and the main workpiece fed by the feeding assembly.

[0067] The adjustable installation of the welding equipment 17 means that the welding equipment 17 can be angled.

[0068] Example 2: The difference from the example is that the positioning component includes a positioning member 11 installed on the lifting plate 10, a weighing plate 18 is coaxially rotatably mounted on the positioning member 11, and a second motor is fixed at the bottom of the lifting plate 10, with the output shaft of the second motor coaxially fixed with the weighing plate 18.

[0069] The positioning component 11 includes a base plate, on which an arc-shaped plate is integrally formed, and the arc-shaped plate is elastically arranged.

[0070] In this embodiment of the invention, under normal conditions, the opening of the arc plate faces the preheating chamber. After the main workpiece is preheated, the main workpiece is moved toward the positioning member 11 by the pushing component. When the main workpiece contacts the arc plate, since the workpiece is disc-shaped, it drives the two arc plates to deform and move in opposite directions. When the main workpiece moves to the center of the disc of the positioning member 11, the arc plate is reset by the elastic potential energy generated during deformation. Similarly, when the main workpiece is taken off the positioning member 11, its motion state is the same.

[0071] Among them, the weighing plate 18 and the support arm 16 are driven to rotate relative to each other / opposite by the first motor 8 and the second motor. When the weighing plate 18 rotates, the main workpiece is driven to rotate accordingly, and when the support arm 16 rotates, the welding equipment 17 is driven to rotate accordingly.

[0072] During welding, the welding equipment 17 rotates around the center of the main workpiece. The welding equipment 17 needs to complete one full rotation to complete the welding of the main workpiece and the auxiliary workpiece. In this embodiment, welding is achieved by driving the welding equipment 17 to rotate relative to the main workpiece, thereby reducing the stroke of the welding equipment 17 and reducing the welding time.

[0073] As an auxiliary feature of this embodiment, the positioning member 11 is provided with a ring gear on the disc body, and a drive gear that meshes with the ring gear is rotatably installed on the processing box 1. The drive gear is provided with a handle, and the drive gear can be rotated by rotating the handle. When the drive gear rotates, the positioning member 11 is rotated 180° through the ring gear, so that the arc-shaped plate opening side of the positioning member 11 rotates toward the discharge port opened on the processing box 1, so as to facilitate the removal of the main workpiece.

[0074] This embodiment not only positions the main workpiece but also reduces welding time and facilitates material unloading.

[0075] As another embodiment of the present invention, the rotation of the support arm 16 and the weighing plate 18 in the previous embodiment is driven by two motors, while the distinguishing feature of this embodiment is that: a first transmission rod 21 is coaxially fixed at the bottom of the weighing plate 18, the first transmission rod 21 passes through the bottom of the processing box 1, a transmission cylinder 25 is rotatably installed in the welding cavity, the transmission cylinder 25 is sleeved on the outside of the first transmission rod 21 and slidably connected to it, and a second transmission rod 23 is rotatably installed on the outside of the processing box 1;

[0076] The top of the processing box 1 is rotatably mounted with a gear set 24. The gear set 24 includes two meshing gears. One gear set 24 and the transmission cylinder 25 are both connected to the second transmission rod 23 through a transmission chain 22. The other gear is coaxially fixed with the support arm 16.

[0077] In this embodiment, the first motor 8 drives the transmission cylinder 25 or the gear set 24 to rotate, and the rotation of the gear set 24 drives the weighing plate 18 to rotate relative to the support arm 16.

[0078] In this embodiment, a transmission bar is fixed to the outside of the first transmission rod 21, and a transmission groove is provided on the inner wall of the transmission cylinder 25, so that the first transmission rod 21 and the transmission cylinder 25 can slide relative to each other. The "transmission bar" and "transmission groove" in this invention have the same structure and the same effect.

[0079] The thickness of the limiting block 14 is half that of the positioning block 13, and the distance between the limiting block 14 and the bottom of the preheating chamber is greater than the thickness of the preheating component.

[0080] In this embodiment, under normal conditions, the limiting block 14 abuts against the top wall of the preheating chamber, so that when the main workpiece is pushed into the preheating chamber by the feeding component 6, the limiting block 14 will not block the main workpiece from being pushed in.

[0081] The feeding assembly includes a feeding box 12, which is fixed to the positioning member 11 or the inner wall of the welding cavity by a connecting plate. A feeding box cover 19 is rotatably and detachably installed on the feeding box 12.

[0082] The feeding box 12 is fixed with two limiting plates arranged in a snail shape. The feeding box cover 19 is provided with a snail-shaped slot between the two limiting plates. The ends of the two limiting plates are provided with a discharge port 15 communicating with them. The discharge port 15 is concentrically arranged with the weighing tray 18.

[0083] A pusher assembly connected to the welding assembly is installed on the feed box cover 19.

[0084] In this embodiment of the invention, the sub-workpiece is placed between two limiting plates in sequence. When the welding assembly is working, it drives the pushing assembly to work. When the pushing assembly is working, it pushes the sub-workpiece between the two limiting plates into the discharge port 15 to perform the functions of material discharge and material feeding.

[0085] The bottom of the feeding box 12 is fixed with a feeding pipe, which is concentrically arranged and connected with the feeding port 15.

[0086] In this embodiment of the invention, during welding, the lifting plate 10 raises the main workpiece to the end of its stroke, and then the welding assembly operates. The operation of the welding assembly drives the pushing assembly to operate, so as to put the auxiliary workpiece out of the feeding port 15. The auxiliary workpiece is guided by the feeding tube to move to the center position of the main workpiece. At this time, the welding operation is started. The auxiliary workpiece is not in the feeding tube. The feeding tube limits the auxiliary workpiece. After the welding is completed, the lifting plate 10 descends and the auxiliary workpiece is separated from the feeding tube. Please refer to Figure @.

[0087] In this embodiment, the connection between the feeding box 12 and the inner wall of the welding cavity is established.

[0088] In another embodiment of this invention, the feeding box 12 is installed on the positioning member 11 and still uses a feeding tube. When the length of the feeding tube in this embodiment is such that the auxiliary workpiece is just separated from the feeding tube when the material is fed through the feeding tube, the auxiliary workpiece is separated from the feeding tube when the material is fed through the feeding tube. Since the feeding tube continuously guides the auxiliary workpiece during feeding, the auxiliary workpiece is separated from the feeding tube when it falls to the point of contact with the main workpiece. This method requires adding damping material inside the feeding tube to reduce the falling speed and avoid the auxiliary workpiece from bouncing up due to excessive speed, which would cause positional deviation.

[0089] It should also be noted that since the main workpiece and the welding equipment 17 rotate relative to each other, the welding equipment 17 does not need to be rotated during welding. Therefore, the connecting plate connecting the feed box 12 and the positioning part 11 / welding cavity inner wall will not interfere with the welding equipment 17.

[0090] The feeding assembly includes a toothed ring 31 coaxially rotatably mounted on the feeding box cover 19. A transmission plate 32 is fixed on one side of the toothed ring 31. A feeding block 33 is slidably mounted on the transmission plate 32. The feeding block 33 is located in the groove of the feeding box cover 19.

[0091] A toothed ring 31 is rotatably mounted inside the toothed ring 31 and coaxially fixed on the toothed ring 31. A third gear 29 is also rotatably mounted inside the toothed ring 31 and coaxially fixed on the third gear 31. A first incomplete gear 28 is coaxially fixed on the third gear 26 and the first incomplete gear 28 cooperates with the third gear 29.

[0092] The outer side of the third transmission rod 26 is fitted with a transmission tube that slides with it. A second gear 27 is coaxially fixed at the end of the transmission tube. The second gear 27 meshes with the first gear 20, and the transmission tube is also rotatably connected to the shaft of the first gear 20. In this embodiment, the transmission tube is not shown. A transmission bar is fixed on the third transmission rod 26. The transmission bar slides with a transmission groove opened in the transmission tube. The transmission bar and the transmission groove allow the third transmission rod 26 and the transmission tube to slide relative to each other, and the transmission tube and the third transmission rod 26 rotate synchronously.

[0093] In this embodiment of the invention, the transmission tube is rotatably connected to the shaft of the first gear 20 via a connecting member rotatably connected thereto, and the transmission tube is rotated at a known position via the connecting member;

[0094] When the support arm 16 rotates, it drives the second gear 27 to rotate through the first gear 20, which in turn drives the transmission tube to rotate. The transmission tube drives the third transmission rod 26 to rotate through the transmission groove and transmission bar. When the third transmission rod 26 rotates, it drives the third gear 29 to rotate through the first incomplete gear 28. Since the second incomplete gear 30 and the third gear 29 are coaxially fixed, the second incomplete gear 30 rotates synchronously when the third gear 29 rotates, and drives the gear ring 31 to rotate through the second incomplete gear 30.

[0095] When the gear ring 31 rotates, it drives the pusher block 33 to rotate through the transmission plate 32. Since the pusher block 33 is located in the volute groove of the feed box cover 19, it plays a guiding role. When the gear ring 31 drives the pusher block 33 to rotate through the transmission plate 32, the pusher block 33 moves along the path of the groove of the feed box cover 19. When the pusher block 33 moves, it will push the auxiliary workpiece to move.

[0096] The third gear 29 is in a state where it does not have a transmission relationship with the gear ring 31; while the gear ratio of the first incomplete gear 28 and the second incomplete gear 30 can be adjusted according to the actual size of the auxiliary workpiece, and is not specifically limited in this application.

[0097] This invention also provides a low-temperature welding method for cast steel parts and steel components, wherein the low-temperature welding method for cast steel parts and steel components employs the aforementioned welding system for cast steel parts and steel components, and includes the following steps:

[0098] Step 1: Place the auxiliary workpiece inside the feeding assembly, and then push the main workpiece into the preheating chamber;

[0099] Step 2: Heat the required welding position of the main workpiece using the heating components installed in the preheating chamber, and position the main workpiece in the heating chamber.

[0100] After heating is complete, the main workpiece is pushed onto the positioning assembly for positioning, and then the welding assembly begins operation;

[0101] Step 3: When the welding assembly is working, it drives the feeding assembly to work. The feeding assembly puts the auxiliary workpiece into the required welding position, and the welding assembly welds the main workpiece and the auxiliary workpiece to complete the welding work.

[0102] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
