Description

Technical Field

[0001] The present invention belongs to the technical field of manufacturing other metal processing machinery, and specifically relates to an automatic stainless steel plate welding and splicing equipment. Background Art

[0002] In the prior art, for the welding and manufacturing of stainless steel products such as stainless steel sinks, the operation process is as follows: First, cut the stainless steel plate into appropriate shapes, and then bend the four sides of the cut stainless steel plate, that is, the part that serves as the sink wall, so that the stainless steel plate forms the shape of a sink. After this step is completed, then use the automatic stainless steel plate welding and splicing equipment to carry out the welding work at the joint position of the stainless steel plate. In this way, the manufacturing of the stainless steel sink is finally completed.

[0003] A patent with the publication number CN118081373A discloses an automatic stainless steel plate welding machine, including a workbench; first, the user needs to place the cut stainless steel plate on the receiving plate on the top surface of the rotating table, and then the linear motor on the top surface of the rotating table starts and drives the push plate to move towards the receiving table. During this process, the push plate will squeeze the folding plate, causing the folding plate to finally rotate ninety degrees, and the flipped folding plate will drive the stainless steel plate on it to bend, thereby splicing the cut stainless steel plate into the shape of a sink. Subsequently, the rotating table on the workbench rotates to align the joint of the stainless steel sink with the welding assembly, and the welding assembly welds the joint formed by the splicing of the stainless steel plates, thus completing the manufacturing of the stainless steel sink.

[0004] The above solution still has some problems in actual use. When the stainless steel plate is placed on the receiving plate, its initial position may have slight deviations, and there is no limit on the other side of the stainless steel plate during the squeezing and bending process of the folding plate, and there is no corresponding auxiliary positioning structure to ensure that the stainless steel plate moves strictly along the preset trajectory during folding. This easily leads to the crease deviating from the expected position. If the crease is not in the preset position, it will affect the subsequent splicing accuracy and welding quality of the stainless steel sink, reduce the product qualification rate, and increase the production cost.

[0005] Therefore, the present invention provides an automatic stainless steel plate welding and splicing equipment. Summary of the Invention

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0023] Example 1: As Figures 1 to 10As shown in the figure, an automatic butt welding device for stainless steel plates according to an embodiment of the present invention includes a machine body. A welding assembly is arranged on one side of the machine body. The welding assembly is used for welding the edges of the spliced stainless steel plates. The welding assembly includes a connecting frame fixedly connected to one side of the machine body. A support frame is slidably connected to one side of the connecting frame. A lead screw is rotatably connected inside the support frame. An auxiliary plate is slidably connected to the circumferential surface of the lead screw. One end of the auxiliary plate is fixedly connected with a welding head. A support frame is fixedly connected to the upper surface of the machine body. A connecting guide rail is fixedly connected to the lower surface of the support frame. A hydraulic cylinder is slidably connected to the lower surface of the connecting guide rail. The output end of the hydraulic cylinder is fixedly connected with a pressing disc. A chassis is rotatably connected to the upper surface of the machine body. A rectangular plate is fixedly connected to the upper surface of the chassis. Rotating plates are rotatably connected to each side of the chassis corresponding to the rectangular plate. The rotating plates are used for folding the stainless steel plates; a limiting assembly is arranged at the top end of the rotating plate. The limiting assembly includes a positioning guide rail fixedly connected to the upper surface of the rotating plate. A positioning groove is opened on one side of the positioning guide rail. A baffle is slidably connected in the positioning groove through a positioning block. Support plates are fixedly connected to both sides of the rotating plate. A support member for supporting the baffle is arranged inside the support plates. The support member includes a limiting groove opened inside the support plates. A compression spring is fixedly connected inside the limiting groove. One end of the compression spring is fixedly connected with a latching plate. A tapered plate is fixedly connected to one side of the latching plate; a spraying assembly is also arranged inside the support plates. When the baffle slides down to limit the stainless steel plate, the spraying assembly is triggered, and a flux spraying operation is carried out on the edges of the stainless steel plate through spray pipes fixedly connected to both sides of the support plates.

[0024] Specifically, when the stainless steel plate is placed on the receiving plate, there may be slight deviations in its initial position. During the extrusion and bending process of the folding plate, the other side does not limit the stainless steel plate, and there is no corresponding auxiliary positioning structure to ensure that the stainless steel plate moves strictly along the preset trajectory during folding. This easily leads to the crease deviating from the expected position. If the crease is not in the preset position, it will affect the subsequent splicing accuracy and welding quality of the stainless steel sink, reduce the product qualification rate, and increase the production cost; Therefore, the present invention is configured with the above structure to solve the above problems. First, in this stainless steel plate welding equipment, after the stainless steel plate is placed on the rectangular plate, the rotating plate is used to fold the stainless steel plate. During the folding process, to solve the problems of the initial position deviation of the stainless steel plate and the lack of effective limit during folding, a limit component is provided. The limit work is carried out through the baffle on the positioning guide rail at the top of the rotating plate. Specifically, the pressing plate at the bottom of the hydraulic cylinder sucks the stainless steel plate onto the upper surface of the rectangular plate because several suction cups are provided on the lower surface of the pressing plate. Then the pressing plate continues to move downward, pushing the stainless steel plate to squeeze the support member. During the squeezing process, the stainless steel plate squeezes the tapered plate, causing the tapered plate to drive the overlapping plate to retract into the limit groove. Then the baffle loses the overlap of the overlapping plate and thus falls. At this time, the baffle will accurately position the folding point of the stainless steel plate, and then the folding work is carried out through the folding of the rotating plate, thus ensuring the accuracy of the folding work. At the same time, during the sliding process of the baffle, the spraying component will be triggered, so that the spray pipes fixedly connected to both sides of the support plate spray flux on the edge of the stainless steel plate; On the one hand, the baffle of the limit component effectively limits the stainless steel plate during the folding process, can overcome the influence brought by the slight deviation of the initial position of the stainless steel plate, ensure that the stainless steel plate moves strictly along the preset trajectory during folding, make the crease accurately in the expected position, thus greatly improving the splicing accuracy of the subsequent stainless steel sink. On the other hand, the spraying component is triggered during the sliding and limiting process of the baffle, and the flux can be sprayed on the edge of the stainless steel plate in time, preparing for the subsequent welding work, which helps to improve the welding quality. The improvement of the splicing accuracy and welding quality can effectively reduce the probability of product defects, improve the qualified rate of products, reduce rework and waste caused by quality problems, and thus reduce the production cost, improve the production efficiency and economic benefits; It solves the problem that the crease is not in the preset position due to the lack of limitation on the stainless steel plate.

[0025] Such as Figure 2 shown, the surface of the chassis of this embodiment is fixedly connected with a slide rail, the surface of the slide rail is slidably connected with a slide plate, a rotating groove is opened on one side of the rotating plate, the slide plate is slidably connected with the rotating groove, and one end of the slide rail close to the rotating plate is high and the end far from the rotating plate is low. During the folding process, it is used to push the stainless steel plate to carry out the folding work.

[0026] Specifically, since a slide rail is fixedly connected to the surface of the chassis, the slide plate is slidably connected to the slide rail, a rotating groove is opened on one side of the rotating plate, and the slide plate is slidably connected with the rotating groove. Moreover, one end of the slide rail close to the rotating plate is high and the end far from the rotating plate is low. During the folding process, the slide plate will slide along the inclined slide rail towards the direction close to the rotating plate under the driving action of the guide rail. Since the slide plate is slidably connected with the rotating groove, the slide plate will exert a thrust on the rotating plate during the movement, causing the rotating plate to rotate around its rotation axis, and then pushing the stainless steel plate placed on the rectangular plate to carry out the folding work, realizing the bending and forming of the stainless steel plate; By using the inclined setting of the slide rail and the cooperation between the skateboard and the rotating groove, the stainless steel plate can be stably and accurately pushed to be folded, ensuring the coherence and accuracy of the folding action, which helps to improve the quality and efficiency of the stainless steel plate folding, reduce defective products caused by incomplete or unstable folding, lower the production cost, and enhance the overall quality of the product.

[0027] As Figure 5 shown, the limit component of this embodiment further includes a connection groove opened on the surface of the support plate. Corresponding to each connection groove on the upper surface of the baffle plate, a connection plate is fixedly connected. The connection plate slides along the connection groove, and an electric push rod is fixedly connected to the bottom wall of the positioning groove.

[0028] Specifically, after the stainless steel plate is placed on the rectangular plate, the stainless steel plate first contacts the support member on the support plate, releasing the baffle plate to fall. The falling baffle plate slides stably along the connection groove through the two connection plates on the upper surface to limit the stainless steel plate placed on the rectangular plate. Then, rotate the rotating plate to perform the folding work. After the folding work is completed, drive the electric push rod. The electric push rod pushes the positioning block to move the baffle plate upward. Then, the baffle plate is lapped on the lap plate again for clamping. After the folding work is completed, drive the welding head to weld the edge of the stainless steel plate. After the welding is completed, start the electric push rod again. The electric push rod pushes the positioning block to move the baffle plate upward to reset and lap on the lap plate for clamping. The operation is convenient, reusable, improves production efficiency and product quality, and reduces the defective rate.

[0029] As Figure 6 shown, several connection holes are opened on the surface of the connection plate of this embodiment, fixing holes are opened on the inner wall of the connection groove, and a seal is arranged on one side of the support plate for sealing the fixing holes on the inner wall of the connection groove in the initial state. The seal includes an auxiliary frame fixedly connected to one side of the support plate, several springs are fixedly connected inside the auxiliary frame, and one same trapezoidal plate is fixedly connected to one ends of the several springs.

[0030] Specifically, when the baffle plate moves downward, it will simultaneously drive the connection plate to slide down along the connection groove. When the connection plate slides down, the connection holes opened on its surface will be sequentially communicated with the fixing holes. At this time, the pressure pump inside the support plate will pressurize the transfer stored inside, from the fixing hole through the connection hole, and finally spray it to the end face of the stainless steel plate from the spray pipe, and it matches the process of the baffle plate sliding down. When the connection plate is completely stuck in the connection groove, the connection hole and the fixing hole are misaligned and not aligned, and the flux cannot be sprayed anymore. By driving the connection plate to slide down by the downward movement of the baffle plate, the connection hole is communicated with the fixing hole, and the pressure pump accurately sprays the flux to the end face of the stainless steel plate, matching the process of the baffle plate sliding down, ensuring timely spraying before folding. After the connection plate is stuck in the connection groove, the hole positions are misaligned and spraying stops, avoiding waste, and improving spraying accuracy and production efficiency.

[0031] Embodiment 2: As Figures 1 to 10As shown in the figure, compared with the first comparative example, another implementation manner of the present invention is as follows: cleaning components are provided on both sides of the baffle. The cleaning components include rotating frames fixedly connected to the bottom ends on both sides of the baffle. An auxiliary groove is formed on the side of the rotating frame close to the baffle, and an auxiliary roller is rotatably connected in the auxiliary groove. Positioning columns are rotatably connected to both sides of the baffle, and the positioning columns are controlled by a built-in motor of the baffle. A torsion spring is sleeved on the circumferential surface of the positioning column, and the rotating frame is fixedly connected to the positioning column through the torsion spring, and the rotating frame is in an inclined state in the initial state.

[0032] Specifically, when the baffle moves downward, the inclined cleaning components at both bottom ends thereof clean the end faces of the stainless steel plates. During the downward movement of the baffle, the auxiliary rollers rotate passively to clean the stainless steel plates. When the two steel plates are about to approach, the built-in micro-motor of the baffle is driven to rotate, and then the positioning column is driven to rotate, so as to drive the rotating frame to stand upright on both sides of the baffle. By driving the cleaning components through the downward movement of the baffle, the end faces of the stainless steel plates can be cleaned in time during the downward movement of the baffle, impurities can be removed, and the welding quality can be guaranteed. When the two steel plates are about to approach, the upright rotating frame can avoid interfering with subsequent welding and other operations of the cleaning components. At the same time, the existence of the torsion spring enables the rotating frame to be flexibly reset. The whole cleaning process has a high degree of automation, improving production efficiency and product quality.

[0033] Working principle: First, in this stainless steel plate butt welding device, after the stainless steel plate is placed on the rectangular plate, the rotating plate is used to fold the stainless steel plate. During the folding process, in order to solve the problems of the initial position deviation of the stainless steel plate and the lack of effective limit during folding, a limit component is provided, and the baffle on the positioning guide rail at the top end of the rotating plate is used for limiting work. Specifically, the stainless steel plate is sucked to the upper surface of the rectangular plate by the pressing plate at the bottom end of the hydraulic cylinder, because a plurality of suction cups are provided on the lower surface of the pressing plate. Then the pressing plate continues to move downward, pushing the stainless steel plate to squeeze the support member. During the squeezing process, the stainless steel plate squeezes the tapered plate, so that the tapered plate drives the overlapping plate to retract into the limit groove, and then the baffle loses the overlap of the overlapping plate and thus falls. At this time, the baffle will accurately position the folding position of the stainless steel plate, and then the folding work is carried out through the folding of the rotating plate. Specifically, since a slide rail is fixedly connected to the bottom surface of the chassis, a slide plate is slidably connected to the slide rail, a rotating groove is formed on one side of the rotating plate, the slide plate is slidably connected to the rotating groove, and one end of the slide rail close to the rotating plate is high and the end far from the rotating plate is low. During the folding process, the slide plate will slide along the inclined slide rail towards the direction close to the rotating plate under the driving action of the guide rail. Since the slide plate is slidably connected to the rotating groove, the slide plate will apply a thrust to the rotating plate during the movement, so that the rotating plate rotates around its rotation axis, and then the stainless steel plate placed on the rectangular plate is pushed to fold, realizing the bending and forming of the stainless steel plate. By utilizing the inclined setting of the sliding rail and the cooperation between the sliding plate and the rotating groove, the stainless steel plate can be stably and precisely pushed to fold, ensuring the coherence and accuracy of the folding action, contributing to improving the quality and efficiency of the stainless steel plate folding, reducing defective products caused by incomplete or unstable folding, lowering production costs, and enhancing the overall product quality, thereby ensuring the accuracy of the folding work. Meanwhile, during the sliding process of the baffle, the spraying component will be triggered, causing the spray pipes fixedly connected to both sides of the support plate to perform flux spraying on the edges of the stainless steel plate; On the one hand, the baffle of the limiting component effectively limits the stainless steel plate during the folding process, capable of overcoming the influence brought by the slight deviation of the initial position of the stainless steel plate, ensuring that the stainless steel plate moves strictly along the preset trajectory during folding, making the crease accurately located at the expected position, thus greatly improving the splicing accuracy of the subsequent stainless steel sink. On the other hand, during the sliding and limiting process of the baffle, the spraying component is triggered, enabling timely flux spraying on the edges of the stainless steel plate, preparing for the subsequent welding work, contributing to improving the welding quality. The improvement of the splicing accuracy and welding quality can effectively reduce the probability of product defects, increase the qualified rate of products, reduce rework and waste caused by quality problems, and thus lower production costs and improve production efficiency and economic benefits; In addition, when the baffle moves downward, it will simultaneously drive the connecting plate to slide down along the connecting groove. As the connecting plate slides down, the connecting holes opened on its surface will sequentially communicate with the fixing holes. At this time, the pressure pump inside the support plate will pressurize the transfer fluid stored inside, from the fixing holes through the connecting holes, and finally spray it from the spray pipe to the end face of the stainless steel plate, and it matches the sliding process of the baffle. When the connecting plate is completely stuck in the connecting groove, the connecting holes and the fixing holes are misaligned and do not align, and the flux can no longer be sprayed. By driving the connecting plate to slide down by the downward movement of the baffle, the connecting holes communicate with the fixing holes, and the pressure pump precisely sprays the flux to the end face of the stainless steel plate, matching the sliding process of the baffle, ensuring timely spraying before folding. After the connecting plate is stuck in the connecting groove, the hole positions are misaligned and spraying stops, avoiding waste and improving spraying accuracy and production efficiency; After the folding work is completed, the welding head is driven to weld the edges of the stainless steel plate. After welding is completed, the electric push rod is started. The electric push rod pushes the positioning block to make the baffle move upward, and then the baffle is lapped on the lap plate again for clamping. After folding, the electric push rod pushes the positioning block to make the baffle move upward and reset and lap on the lap plate for clamping. The operation is convenient, reusable, improves production efficiency and product quality, and reduces the defective rate.
