Description

Technical Field

The inner tank of the electric kettle is the core component of the electric kettle. The production quality of the inner tank of the electric kettle directly affects the later assembly and use. When processing the stainless steel inner tank of the electric kettle, a forming machine is needed. The forming machine includes bending forming and welding forming.

[0003] The existing stainless steel inner tanks of electric kettles are processed by a combination of machinery and manpower. The worker first puts one end of the steel plate into a bending machine, which bends one end of the steel plate. Then the steel plate is taken out and the other end is bent. The worker then puts the bent steel plate into a welding machine for welding, welding the steel plate into a frustum-like shape. The worker then takes out the welded inner tank and performs subsequent operations.

[0004] In the prior art, when processing the inner tank of a hot water kettle, it is necessary to first bend the steel plate into a cylindrical shape. After the steel plate is bent into the cylindrical shape, the two sides of the steel plate will overlap together, and then the initially cylindrical steel plate needs to be transferred to a welding machine for welding. Since the gap on the side of the steel plate bent into the cylinder has not been welded yet, during batch transfer, multiple cylindrical steel plates are pushed together, collided and squeezed with each other, which may cause the gap on the side of the steel plate bent into the cylinder to be staggered, causing deformation of the cylinder, thereby producing a large number of defective products.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Embodiment 1

[0032] like Figure 1-Figure 2 , Figure 6 As shown, an automatic forming machine for a kettle liner according to an embodiment of the present invention comprises a cylindrical wheel 1, a first circular ring 11 is provided on one side of the cylindrical wheel 1, a side plate 2 is fixedly connected to one side of the first circular ring 11, a top plate 3 is fixedly connected to one side of the upper end of the side plate 2, a sliding assembly is provided at the lower end of the cylindrical wheel 1, the sliding assembly comprises a first rotating wheel 13 slidably arranged on both sides of the first circular ring 11, a welding assembly is provided at the lower end of the top plate 3, the welding assembly comprises a welding head 33 located at the lower end of the top plate 3, an extrusion assembly is provided at one side of the welding head 33, and the extrusion assembly comprises an arc block 36 located at one side of the welding head 33.

[0033] Specifically, when the inner liner of a hot water bottle is processed and formed, the steel plate needs to be bent into a cylindrical shape first, and then the initially formed inner liner of the hot water bottle is transferred to a welding machine for welding. When a batch of inner liner of the hot water bottle is transferred to the welding station, the inner liner of the hot water bottle may be deformed due to the mutual collision and extrusion of multiple inner liner of the hot water bottle. When using the forming machine, the steel plate is placed between the cylindrical wheel 1 and the first rotating wheel 13, so that the cylindrical wheel 1 is located in the middle of the steel plate, and then the first rotating wheel 13 is driven to slide on one side of the first circular ring 11, so that the first rotating wheel 13 slides along the side walls of both sides of the cylindrical wheel 1, and drives the steel plate to fit the side wall of the cylindrical wheel 1, so that the steel plate forms a cylinder. At this time, the two ends of the steel plate cannot be completely fitted with the side wall of the cylindrical wheel 1, and the arc block 36 is driven to slide downward, so that one end of the arc surface of the arc block 36 contacts the two ends of the steel plate, and the arc The arc block 36 continues to move downward, driving the two ends of the steel plate to be close to the side wall of the cylindrical wheel 1. At this time, the steel plate is completely fitted with the outer surface of the cylindrical wheel 1 to form a cylinder. Then the welding head 33 is driven to move downward to weld the gaps at both ends of the steel plate. The welding head 33 is connected to the welding machine through a harness. A laser welding machine is used to drive the first rotating wheel 13 to drive the steel plate to wrap around the outside of the cylindrical wheel 1 to form a cylinder. Then the arc block 36 is driven to squeeze the two ends of the steel plate so that the two ends of the steel plate are close to the surface of the cylindrical wheel 1 so that the two sides of the steel plate overlap. Then the welding head 33 is driven to weld the overlapping parts of the two ends of the steel plate, so that the inner liner of the kettle is initially formed. After the steel plate is bent into a cylinder, there is no need to transfer it to the welding machine for welding, which solves the problem that multiple inner liner of the kettle may be pushed together, collided and squeezed with each other, which may cause deformation of the inner liner of the kettle, thereby improving the qualified rate of the product.

[0034] like Figure 2 As shown, support assemblies are respectively provided on both sides of the lower end of the cylindrical wheel 1, and the support assemblies are respectively located on both sides of the first rotating wheel 13. The support assemblies include a plurality of second rotating wheels 14, and both ends of the plurality of second rotating wheels 14 are respectively rotatably connected with U-shaped blocks 141, and the lower ends of the U-shaped blocks 141 are commonly fixed with second rectangular plates 142.

[0035] Specifically, before bending the steel plate, the steel plate is first placed on the upper end of the second wheels 14 so that the steel plate is located between the cylindrical wheel 1 and the first wheel 13. The second wheels 14 support the steel plate to facilitate adjustment of the steel plate so that the steel plate can be located in the middle of the lower end of the cylindrical wheel 1.

[0036] like Figure 3As shown, two third rotating wheels 15 are provided at the lower end of the first rotating wheel 13, and waist-shaped blocks 151 are rotatably connected at both ends of the third rotating wheel 15. The lower end of the waist-shaped block 151 is fixedly connected to a third cylindrical rod 152, and the lower end of the third cylindrical rod 152 can slide in the first cylinder 154. The third cylindrical rod 152 is fixedly connected to the inside of the first cylinder 154 through a first spring 153, and the first cylinder 154 can slide in the middle of the second rectangular plate 142. The output end of the second electric telescopic rod 155 is fixedly connected to the lower end of the second rectangular plate 142, and the lower end of the second electric telescopic rod 155 is fixedly connected to the rectangular base 144.

[0037] Specifically, when the first rotating wheel 13 drives the steel plate to fit along the side wall of the cylindrical wheel 1, the second electric telescopic rod 155 is driven to contract to drive several second rotating wheels 14 to move downward through the second rectangular plate 142. When the second rectangular plate 142 drives the second rotating wheels 14 to move downward, the second rectangular plate 142 moves downward along the outer side of the first cylinder 154 to facilitate the movement of the first rotating wheel 13. When the first rotating wheel 13 moves to both sides of the cylindrical wheel 1, the first spring 153 releases the elastic force to drive the third rotating wheel 15 to push upward through the third cylindrical rod 152, so that the third rotating wheel 15 is close to the lower end of the steel plate, which can clamp the steel plate to prevent slipping.

[0038] like Figure 4-Figure 5 As shown, adjustment components are respectively provided on both sides of the cylindrical wheel 1, and the adjustment components include third rectangular plates 22 respectively provided on both sides of the cylindrical wheel 1, first rectangular holes 21 are respectively provided on both sides of the side plate 2, rectangular frames 211 are slidably provided inside the first rectangular holes 21, and the third rectangular plate 22 can slide inside the rectangular frame 211 through the first rectangular block 224, and third rectangular bars 222 are respectively provided at the lower ends of the third rectangular plates 22, and a rectangular tube 23 is fixedly connected to the side of the first rectangular block 224 away from the third rectangular plate 22, and a fourth rectangular bar 231 is slidably connected to the opposite sides of the two rectangular tubes 23, and the output end of the third electric telescopic rod 232 is fixedly connected to the lower end of the middle part of the fourth rectangular bar 231, and the lower end of the third electric telescopic rod 232 is fixedly connected to one side of the side plate 2 through the second rectangular block 233.

[0039] Specifically, after the steel plate is placed on the upper end of the second rotating wheel 14, it is necessary to adjust the steel plate. When necessary, the steel plate is located in the middle of the lower end of the cylindrical wheel 1 to facilitate subsequent welding. The third electric telescopic rod 232 is driven to contract and the fourth rectangular bar 231 is driven to move downward. The fourth rectangular bar 231 drives the third rectangular plate 22 to move downward through the rectangular tube 23. At the same time, the rectangular frame 211 is driven to slide downward in the first rectangular hole 21 through the first rectangular block 224, so that the third rectangular plate 22 squeezes the lower ends of both sides of the upper end of the steel plate, and then the rectangular tubes 23 on both sides are driven to slide toward the middle of the fourth rectangular bar 231 at the same time, so that the third rectangular plates 22 on both sides drive the third rectangular bar 222 to slide toward both sides of the steel plate until they overlap with both sides of the steel plate and center the steel plate.

[0040] like Figure 5 As shown, the second rectangular strips 221 are fixedly connected to the sides of the upper ends of the two third rectangular plates 22 away from each other. The third rectangular strips 222 penetrate the third rectangular plates 22 and can slide inside the second rectangular strips 221. The third rectangular strips 222 are fixedly connected to the inside of the second rectangular strips 221 via third springs 223.

[0041] Specifically, when the third rectangular plate 22 moves downward, it drives the third rectangular bar 222 to fit with the second rotating wheel 14. Since the second rotating wheel 14 is cylindrical, the third rectangular bar 222 can slide in the second rectangular bar 221 and squeeze the third spring 223, so that the third rectangular bar 222 is always in close contact with the surface of the second rotating wheel 14, preventing the third rectangular bar 222 from forming a gap with the second rotating wheel 14 and preventing the side wall of the steel plate from contacting.

[0042] like Figure 6-Figure 7 As shown, the welding assembly also includes a slide rail 31 fixed to the lower end of the top plate 3, a slide table 311 is slidably connected to the lower end of the slide rail 31, a second cylinder 32 is fixed to the lower end of the slide table 311, and the welding head 33 can slide inside the second cylinder 32.

[0043] Specifically, after all the steel plates are attached to the surface of the cylindrical wheel 1, the welding head 33 is driven to slide downward in the second cylinder 32 so that the welding head 33 is located at the upper end of the gap between the two ends of the steel plate. Then, the slide 311 is driven to slide at the lower end of the slide rail 31. The slide 311 drives the welding head 33 to move through the second cylinder 32 to weld the gap between the two ends of the steel plate.

[0044] like Figure 7 As shown, a fifth rectangular bar 34 is fixedly connected to one side of the welding head 33, a third cylinder 341 is fixedly connected to the lower end of the fifth rectangular bar 34, a cylindrical block 343 is slidably arranged inside the lower end of the third cylinder 341, the cylindrical block 343 is fixedly connected to the inside of the third cylinder 341 through a fourth spring 342, a fourth rectangular plate 35 is fixedly connected to the lower end of the cylindrical block 343, and the lower end of the fourth rectangular plate 35 is fixedly connected to the arc block 36.

[0045] Specifically, when the welding head 33 slides downward, the welding head 33 drives the third cylinder 341 to move downward through the fifth rectangular bar 34, and the third cylinder 341 drives the fourth rectangular plate 35 and the arc block 36 to slide downward through the cylindrical block 343, so that the arc block 36 squeezes the two ends of the steel plate to make the two ends of the steel plate fit the surface of the cylindrical wheel 1. After the arc block 36 is squeezed, the welding head 33 can immediately start welding to reduce the risk of deformation of the steel plate.

[0046] like Figure 7 As shown, the lower end of the arc block 36 is an arc surface, and a plurality of rollers 361 are rotatably connected inside the arc surface of the lower end of the arc block 36 .

[0047] Specifically, when the arc block 36 is driven to slide downward, the arc block 36 drives the roller 361 to contact the surface of the steel plate, and the roller 361 rolls along the surface of the steel plate to prevent scratches on the surface of the steel plate when the steel plate is squeezed.

[0048] like Figure 7 As shown, a first bevel block 344 is fixedly connected to one side of the lower end of the fifth rectangular bar 34, a second rectangular hole 351 is provided in the middle of the fourth rectangular plate 35, a second bevel block 362 is fixedly connected to one side of the arc block 36, the second bevel block 362 can slide in the second rectangular hole 351, and one side of the bevel of the first bevel block 344 fits with one side of the bevel of the second bevel block 362.

[0049] Specifically, the initial position of the arc block 36 is located at the lower end of the welding head 33. When the welding head 33 drives the arc block 36 to slide downward through the fifth rectangular bar 34 to squeeze the steel plate, the welding head 33 continues to move downward, and the fifth rectangular bar 34 drives the third cylinder 341 to slide on the outside of the cylindrical block 343 and squeeze the fourth spring 342. At the same time, the first bevel block 344 moves downward and slides along the bevel side of the second bevel block 362, so that the second bevel block 362 slides away from the welding head 33. The second bevel block 362 drives the arc block 36 to slide away from the welding head 33, and then the welding head 33 can weld the place where the arc block 36 has squeezed.

[0050] Embodiment 2

[0051] like Figure 1 , Figure 8 As shown, compared with Example 1, another embodiment of the present invention is: a conveyor belt 4 is installed on one side of the side plate 2, a circular plate 12 is provided in the middle of the first circular ring 11 and is fixed to the side plate 2, a second circular ring 121 is slidably provided on the edge of the circular plate 12, the second circular ring 121 can slide on the outside of the cylindrical wheel 1, and the edges of one side of the second circular ring 121 are respectively fixed with first cylindrical rods 122, the first cylindrical rods 122 penetrate the side plate 2, and the first cylindrical rods 122 are fixedly connected to one end away from the second circular ring 121 with a first rectangular plate 123, and the first rectangular plate 123 is fixed to one side of the side plate 2 through a first electric telescopic rod 124.

[0052] Specifically, after the steel plate is welded into shape, the first electric telescopic rod 124 is driven to retract, and the first cylindrical rod 122 is driven to move toward the side close to the cylindrical wheel 1 through the first rectangular plate 123. The first cylindrical rod 122 drives the second ring 121 to move away from the side plate 2. The second ring 121 pushes the initially formed steel plate sleeved on the outside of the cylindrical wheel 1 to one side of the cylindrical wheel 1 for easy removal. Subsequently, the conveyor belt 4 is started to drive the new steel plate to the lower end of the cylindrical wheel 1 for a new round of processing.

[0053] Working principle: start the conveyor belt 4 to convey the steel plate to the upper end of the second rotating wheel 14 until the steel plate is located between the cylindrical wheel 1 and the first rotating wheel 13, then drive the third electric telescopic rod 232 to contract and drive the fourth rectangular bar 231 to move downward, the fourth rectangular bar 231 drives the third rectangular plate 22 to move downward through the rectangular tube 23, and at the same time drives the rectangular frame 211 to slide downward in the first rectangular hole 21 through the first rectangular block 224, so that the third rectangular plate 22 squeezes the lower ends of both sides of the upper end of the steel plate, and then drives the rectangular tubes 23 on both sides to simultaneously move into the fourth rectangular bar 231 The third rectangular plates 22 on both sides slide, so that the third rectangular plates 22 on both sides drive the third rectangular strips 222 to slide toward the two sides of the steel plate until they overlap with the two sides of the steel plate and center the steel plate. When the third rectangular plate 22 moves downward, it drives the third rectangular strips 222 to fit with the second rotating wheel 14. Since the second rotating wheel 14 is cylindrical, the third rectangular strips 222 can slide in the second rectangular strips 221 and squeeze the third springs 223, so that the third rectangular strips 222 are always in close contact with the surface of the second rotating wheel 14, preventing a gap from being generated between the third rectangular strips 222 and the second rotating wheel 14, and preventing the third rectangular strips 222 from contacting the side walls of the steel plate.

[0054] Then, the first rotating wheel 13 is driven to slide on one side of the first ring 11, so that the first rotating wheel 13 slides along the side walls of the cylindrical wheel 1, and drives the steel plate to fit the side walls of the cylindrical wheel 1, so that the steel plate forms a cylinder. When the first rotating wheel 13 moves to both sides of the cylindrical wheel 1, the first spring 153 releases its elastic force and drives the third rotating wheel 15 to push up through the third cylindrical rod 152, so that the third rotating wheel 15 fits closely to the lower end of the steel plate, so that the steel plate can be clamped to prevent slipping.

[0055] After all the steel plates are attached to the surface of the cylindrical wheel 1, the welding head 33 is driven to slide downward in the second cylinder 32. When the welding head 33 slides downward, the welding head 33 drives the third cylinder 341 to move downward through the fifth rectangular bar 34. The third cylinder 341 drives the fourth rectangular plate 35 and the arc block 36 to slide downward through the cylindrical block 343, so that the arc block 36 squeezes the two ends of the steel plate so that the two ends of the steel plate are attached to the surface of the cylindrical wheel 1. After the arc block 36 is squeezed, the welding head 33 continues to move downward, and the fifth rectangular bar 34 drives the third cylinder 341 to slide on the outside of the cylindrical block 343 and squeeze the fourth spring 342. At the same time, the first bevel block 344 moves downward and slides along the bevel side of the second bevel block 362, so that the second bevel block 362 slides away from the welding head 33. The second bevel block 362 drives the arc block 36 to slide away from the welding head 33. Then the welding head 33 can weld the place squeezed by the arc block 36.

[0056] After the steel plate is welded into shape, the first electric telescopic rod 124 is driven to retract, and the first cylindrical rod 122 is driven to move toward the side close to the cylindrical wheel 1 through the first rectangular plate 123. The first cylindrical rod 122 drives the second ring 121 to move away from the side plate 2. The second ring 121 pushes the initially formed steel plate sleeved on the outside of the cylindrical wheel 1 to one side of the cylindrical wheel 1 for easy removal. Subsequently, the conveyor belt 4 is started to drive the new steel plate to the lower end of the cylindrical wheel 1 for a new round of processing.
