Description

Technical Field

[0001] The invention belongs to the technical field of other metal processing machinery manufacturing, in particular to an automatic tailor-welding device for stainless steel plates. Background Art

[0002] The conventional welding process for stainless steel sinks and other products follows this process: First, the stainless steel sheet is cut into the desired shape. The edges of the cut sheet, which will serve as the sink walls, are then bent to create the desired shape. After this step, the seams are welded using automated stainless steel plate welding equipment, completing the stainless steel sink.

[0003] A patent with publication number CN118081373A discloses an automatic welding machine for stainless steel plates, 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 is started, and drives the push plate to move toward the receiving table. During this process, the push plate will squeeze the folding plate, so that the folding plate will eventually rotate ninety degrees, and the flipped folding plate will drive the stainless steel plate on it to bend, and then the cut stainless steel plate will be spliced ​​into the shape of a sink. Then the rotating table on the workbench rotates, and the joints of the stainless steel sink are aligned with the welding assembly. The welding assembly welds the joints formed by the splicing of the stainless steel plates, thereby completing the manufacture of the stainless steel sink.

[0004] There are still some problems in the actual application of the above solution. When the stainless steel plate is placed on the receiving plate, there may be slight deviations in its initial position. The folding plate does not limit the stainless steel plate on the other side during the extrusion and bending process, and there is no corresponding auxiliary positioning structure to ensure that the stainless steel plate moves strictly according to the preset trajectory when folding. This can easily cause the fold to deviate from the expected position. If the fold 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 production costs.

[0005] To this end, the present invention provides an automatic tailor-welding device for stainless steel plates. Summary of the Invention

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0039] Example 1: Figures 1 to 10As shown, an automatic welding device for stainless steel plates described in an embodiment of the present invention includes a machine body, a welding assembly is provided on one side of the machine body, and the welding assembly is used for welding the edges of the stainless steel plates after splicing, and the welding assembly includes a connecting frame fixedly connected to one side of the machine body, a supporting frame is slidably connected to one side of the connecting frame, a screw rod is rotatably connected in the supporting frame, an auxiliary plate is slidably connected to the circumferential surface of the screw rod, and a welding head is fixedly connected to one end of the auxiliary plate, the upper surface of the machine body is fixedly connected to the supporting frame, the lower surface of the supporting frame is fixedly connected to a connecting guide rail, the lower surface of the connecting guide rail is slidably connected to a hydraulic cylinder, the output end of the hydraulic cylinder is fixedly connected to a pressing plate, the upper surface of the machine body is rotatably connected to a chassis, the upper surface of the chassis is fixedly connected to a rectangular plate, and each side of the chassis corresponding to the rectangular plate rotates A rotating plate is connected, and the rotating plate is used to fold the stainless steel plate; a limiting assembly is provided at the top of the rotating plate, and the limiting assembly includes a positioning guide rail fixedly connected to the upper surface of the rotating plate, a positioning groove is provided on one side of the positioning guide rail, and a baffle is slidably connected to the positioning groove through a positioning block, and support plates are fixed on both sides of the rotating plate, and a support member for supporting the baffle is provided inside the support plate, and the support member includes a limiting groove provided inside the support plate, a compression spring is fixed in the limiting groove, one end of the compression spring is fixedly connected to a strap, and one side of the strap is fixed to a cone plate; a spraying assembly is also provided inside the support plate, and when the baffle slides down to limit the stainless steel plate, the spraying assembly is triggered, and flux is sprayed on the edge of the stainless steel plate through the nozzles fixed on both sides of the support plate.

[0040] Specifically, when the stainless steel plate is placed on the receiving plate, there may be a slight deviation in its initial position, and the folding plate does not limit the stainless steel plate on the other side during the extrusion and bending process, and there is no corresponding auxiliary positioning structure to ensure that the stainless steel plate moves strictly according to the preset trajectory when folding, which can easily cause the fold to deviate from the expected position. If the fold 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 production costs;

[0041] Therefore, the present invention sets the above structure to solve the above problems. First, in the 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, in order to solve the problem of initial position deviation of the stainless steel plate and no effective limit during folding, a limit assembly is set. The limit work is performed by the baffle on the positioning guide rail at the top of the rotating plate. 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, the pressing plate continues to move downward to push the stainless steel plate to squeeze the support. During the squeezing process, the stainless steel plate squeezes the cone plate, so that the cone plate drives the strap to retract into the limiting groove, and then the baffle loses the overlap of the strap and falls. At this time, the baffle will accurately locate the folding position of the stainless steel plate, and then the folding work is performed by folding the rotating plate, thereby ensuring the accuracy of the folding work. At the same time, the spray assembly will be triggered during the sliding process of the baffle, so that the nozzles fixed on both sides of the support plate spray flux on the edge of the stainless steel plate.

[0042] On the one hand, the baffle of the limiting component effectively limits the stainless steel plate during the folding process, which can overcome the influence of slight deviations in the initial position of the stainless steel plate and ensure that the stainless steel plate moves strictly according to the preset trajectory during folding, so that the fold is accurately in the expected position, thereby greatly improving the subsequent splicing accuracy of the stainless steel sink. On the other hand, the spraying component is triggered during the baffle sliding and limiting process, which can spray flux on the edge of the stainless steel plate in time to prepare for subsequent welding work, which helps to improve welding quality. The improvement of splicing accuracy and welding quality can effectively reduce the probability of product defects, improve the product qualification rate, reduce rework and waste caused by quality problems, thereby reducing production costs, and improving production efficiency and economic benefits.

[0043] The problem that the stainless steel plate is not limited, resulting in the fold being not in the preset position, is solved.

[0044] like Figure 2 As shown, the surface of the chassis of this embodiment is fixed with a slide rail, and the surface of the slide rail is slidably connected with a slide plate. A rotating groove is provided on one side of the rotating plate, and the slide plate is slidably connected to the rotating groove. The end of the slide rail close to the rotating plate is high, and the end away from the rotating plate is low. During the folding process, it is used to push the stainless steel plate to perform the folding work.

[0045] Specifically, since a slide rail is fixed to the surface of the chassis, a slide plate is slidably connected to the slide rail, a rotating groove is provided on one side of the rotating plate, the slide plate is slidably connected to the rotating groove, and the end of the slide rail close to the rotating plate is higher and the end away from the rotating plate is lower. During the folding process, the slide plate will slide along the inclined slide rail toward 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, causing the rotating plate to rotate around its rotating axis, thereby pushing the stainless steel plate placed on the rectangular plate to perform the folding work, thereby realizing the bending forming of the stainless steel plate;

[0046] By utilizing the inclined setting of the slide rail and the coordination between the slide plate and the rotating groove, the stainless steel plate can be folded stably and accurately, ensuring the continuity 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 inadequate or unstable folding, reduce production costs, and improve the overall quality of the product.

[0047] like Figure 5 As shown, the limiting assembly of this embodiment also includes a connecting groove opened on the surface of the support plate, and a connecting plate is fixedly connected to the position of each connecting groove on the upper surface of the baffle. The connecting plate slides along the connecting groove, and the bottom wall of the positioning groove is fixedly connected to an electric push rod.

[0048] Specifically, when the stainless steel plate is placed on the rectangular plate, the stainless steel plate first contacts the support on the support plate, and the baffle is released to fall. The fallen baffle slides steadily down along the connecting groove through the two connecting plates on the upper surface, limiting the stainless steel plate placed on the rectangular plate, and then the rotating plate is rotated to perform folding. After the folding work is completed, the electric push rod is driven, and the electric push rod pushes the positioning block to move the baffle up, and then the baffle is overlapped on the overlap plate again for clamping. After the folding work is completed, the welding head is driven to weld the edges of the stainless steel plate. After the welding is completed, the electric push rod is started again, and the electric push rod pushes the positioning block to move the baffle up and reset and overlap on the overlap plate for clamping. It is easy to operate and can be reused, which improves production efficiency and product quality and reduces the defective rate.

[0049] like Figure 6 As shown, a plurality of connection holes are provided on the surface of the connecting plate of this embodiment, a fixing hole is provided on the inner wall of the connecting groove, and a sealing member is provided on one side of the support plate for sealing the fixing holes on the inner wall of the connecting groove in the initial state. The sealing member includes an auxiliary frame fixed to one side of the support plate, a plurality of springs are fixed in the auxiliary frame, and one end of the plurality of springs is fixed to the same trapezoidal plate.

[0050] Specifically, 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 on its surface will be connected with the fixed holes in turn. At this time, the pressure pump inside the support plate will pressurize the internally stored transfer, and spray it from the fixed hole through the connecting hole, and finally from the nozzle to the end face of the stainless steel plate, and match the sliding process of the baffle. When the connecting plate is completely stuck in the connecting groove, the connecting hole and the fixed hole are misaligned and not aligned, and the flux can no longer be sprayed. The baffle is moved downward to drive the connecting plate to slide down, so that the connecting hole and the fixed hole are connected. The pressure pump sprays the flux accurately to the end face of the stainless steel plate, matching the sliding process of the baffle to ensure timely spraying before folding. After the connecting plate is stuck in the connecting groove, the hole position is misaligned and spraying is stopped, avoiding waste, and improving spraying accuracy and production efficiency.

[0051] Example 2: Figures 1 to 10 As shown, comparative example 1, another embodiment of the present invention is: cleaning components are provided on both sides of the baffle, the cleaning components include a rotating frame fixed to the bottom ends of both sides of the baffle, an auxiliary groove is provided on the side of the rotating frame close to the baffle, an auxiliary roller is rotatably connected in the auxiliary groove, and positioning columns are rotatably connected on both sides of the baffle, the positioning columns are controlled by the built-in motor of the baffle, a torsion spring is sleeved on the circumferential surface of the positioning columns, the rotating frame is fixed to the positioning columns through the torsion spring, and the rotating frame is in an inclined state in the initial state.

[0052] Specifically, when the baffle moves downward, the inclined cleaning components on both sides of its bottom clean the end surface of the stainless steel plate. During the falling process of the baffle, the auxiliary rollers passively rotate to clean the stainless steel plate. When the two steel plates are about to approach, the micro motor built into the baffle is driven to rotate, and then the positioning column is driven to rotate, so that the driving rotating frame is erected on both sides of the baffle.

[0053] By driving the cleaning assembly by moving the baffle downward, the end face of the stainless steel plate can be cleaned in time during the baffle movement to remove impurities and ensure welding quality. When the two steel plates are about to approach, the rotating frame is erected to avoid interference of the cleaning assembly with subsequent welding and other operations. At the same time, the presence of the torsion spring enables the rotating frame to be flexibly reset. The entire cleaning process is highly automated, which improves production efficiency and product quality.

[0054] Working principle: First, in the 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, in order to solve the problem of initial position deviation of the stainless steel plate and no effective limit during folding, a limit assembly is set, and the limit work is performed by the baffle on the positioning guide rail at the top of the rotating plate. Specifically, the stainless steel plate is sucked to the upper surface of the rectangular plate through the pressing plate at the bottom end of the hydraulic cylinder. Because the lower surface of the pressing plate is provided with a number of suction cups, the pressing plate continues to move downward, pushing the stainless steel plate to squeeze the support. During the extrusion process, the stainless steel plate squeezes the cone plate, so that the cone plate drives the strapping plate to retract into the limit groove, and then the baffle loses the overlap of the strapping plate. The folding plate is fixed to the chassis surface, and the slide is slidably connected to the slide rail. A rotating groove is provided on one side of the rotating plate. The slide is slidably connected to the rotating groove, and the end of the slide rail close to the rotating plate is high and the end away from the rotating plate is low. During the folding process, the slide is driven by the guide rail to slide along the inclined slide rail toward the rotating plate. Since the slide is slidably connected to the rotating groove, the slide exerts a thrust on the rotating plate during movement, causing the rotating plate to rotate around its rotating axis, thereby pushing the stainless steel plate placed on the rectangular plate to perform the folding work, thereby realizing the bending forming of the stainless steel plate.

[0055] By utilizing the inclined setting of the slide rail and the cooperation between the slide plate and the rotating groove, the stainless steel plate can be pushed to fold stably and accurately, ensuring the continuity 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 inadequate or unstable folding, reduce production costs, and improve the overall quality of the product, thereby ensuring the accuracy of the folding work. At the same time, the spray assembly will be triggered during the sliding process of the baffle, so that the nozzles fixed on both sides of the support plate will spray flux on the edge of the stainless steel plate;

[0056] On the one hand, the baffle of the limiting component effectively limits the stainless steel plate during the folding process, which can overcome the influence of slight deviations in the initial position of the stainless steel plate and ensure that the stainless steel plate moves strictly according to the preset trajectory during folding, so that the fold is accurately in the expected position, thereby greatly improving the subsequent splicing accuracy of the stainless steel sink. On the other hand, the spraying component is triggered during the baffle sliding and limiting process, which can spray flux on the edge of the stainless steel plate in time to prepare for subsequent welding work, which helps to improve welding quality. The improvement of splicing accuracy and welding quality can effectively reduce the probability of product defects, improve the product qualification rate, reduce rework and waste caused by quality problems, thereby reducing production costs, and improving production efficiency and economic benefits.

[0057] In addition, when the baffle moves down, it will simultaneously drive the connecting plate to slide down along the connecting groove. As the connecting plate slides down, the connecting holes on its surface will be connected with the fixed holes in turn. At this time, the pressure pump inside the support plate will pressurize the internal stored transfer, and spray it from the fixed hole through the connecting hole, and finally from the nozzle to the end face of the stainless steel plate, and match the sliding process of the baffle. When the connecting plate is completely stuck in the connecting groove, the connecting hole and the fixing hole are misaligned and not aligned, and the flux can no longer be sprayed. The connecting plate is driven to slide down by moving the baffle down, so that the connecting hole and the fixed hole are connected. The pressure pump sprays the flux accurately 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 position is misaligned and spraying stops, avoiding waste and improving spraying accuracy and production efficiency.

[0058] After the folding work is completed, the welding head is driven to weld the edges of the stainless steel plate. After the welding is completed, the electric push rod is started again. The electric push rod pushes the positioning block to move the baffle up, and then the baffle is overlapped on the board again for clamping. After the folding is completed, the electric push rod pushes the positioning block to move the baffle up and reset and overlap on the board for clamping. It is easy to operate and can be reused, which improves production efficiency and product quality and reduces the defective rate.
