Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a metal mesh welding forming machine. Background Art

[0002] Carriage panels are mainly used for the floor panels of various trucks, and are also used with other stamping parts, including anti-collision bumpers, brake sleeves and other small internal parts of automobiles. When welding car panels, a car panel forming and welding machine is often used.

[0003] When the existing carriage plate is used in the forming and welding integrated machine, it is not convenient to adjust the width of the fixed plate containing the carriage plate. At the same time, in the process of clamping the fixed plate, the plate is prone to shaking, which affects the use of welding.

[0004] For example, a forming and welding all-in-one machine disclosed in Chinese patent CN220006498U can drive the transmission rod at the front end to push through the clamping assembly, and a push plate is provided at the top, which is fixedly connected to the fixed rod at the bottom, so that the upper clamping part can be effectively clamped inward or outward in the vertical direction, and the car body panel can be effectively fixed through the matching connection between the threaded rod and the bottom clamping plate.

[0005] However, the welding machine is not equipped with a protective structure and is unable to handle the harmful fumes generated by welding, thus causing harm to surrounding workers.

[0006] For this reason we urgently need to provide a kind of metal mesh welding forming machine with protective structure. Utility Model Content

[0007] The utility model aims to provide a metal mesh welding forming machine to solve the problem that the welding machine proposed in the above background technology has no protective structure and cannot process the harmful fumes generated by welding, thus causing harm to the surrounding workers.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a metal mesh welding forming machine, comprising a workbench and a support column, wherein the support column is fixedly connected to the four corners of the lower side of the workbench, and a welding mechanism is fixedly connected to the upper side of the workbench, and the welding mechanism comprises a protective unit and an adjusting unit, wherein the protective unit is arranged on the upper side of the workbench, and the adjusting unit is arranged at the upper end of the workbench.

[0010] A further improvement is that the upper side of the arc-shaped sealing plate is slidably connected to the lower edge of the top plate, the lower side of the arc-shaped sealing plate is slidably connected to the upper side of the workbench, and the left and right sides of the sliding plate are slidably connected to the side adjacent to the outer arc-shaped plate and the inner arc-shaped plate. Thus, the sliding plate can slide between the outer arc-shaped plate and the inner arc-shaped plate, thereby driving the arc-shaped sealing plate to slide between the outer arc-shaped plate and the inner arc-shaped plate.

[0011] A further improvement is that a circular groove is provided at the lower left end of the connecting plate, a plug hole is provided at the middle position of the lower end of the connecting frame, the outer side of the plug rod is slidably connected to the inner side of the circular groove, the outer side of the lower end of the plug rod is plugged into the inner side of the plug hole, the outer side of the left end of the connecting plate is slidably connected to the inner side of the connecting frame, and the inner side of the exhaust pipe is fixedly connected with an activated carbon filter and a HEPA filter. Thus, after the arc-shaped sealing plates at the left and right ends are pulled to make them contact, and the left end of the connecting plate slides to the inner side of the connecting frame, the plug rod is pushed down by the spring rebound, so that the lower end of the plug rod moves to the plug hole at the lower end of the connecting frame, and the left end of the connecting plate can be fixed to the inner side of the connecting frame, so that the arc-shaped sealing plate is fixed to the front end of the outer arc plate and the inner arc plate, forming a closed welding space, so that the smoke generated during welding can only be discharged from the upper end of the exhaust pipe, and when discharged, it is filtered and purified by the activated carbon filter and the HEPA filter therein, and will not cause harm to the surrounding staff.

[0013] A further improvement is that the left and right ends of the adjusting block are provided with limit holes, the outer side of the limit rod is slidably connected to the inner side of the limit hole, and the upper side of the adjusting block is slidably connected to the lower side of the horizontal part of the support frame. Therefore, when the adjusting block moves, it can only slide along the outer side of the limit rod, thereby limiting the movement of the adjusting block and the cylinder and welding head at its lower end.

[0014] A further improvement is that a threaded hole is provided in the middle of the adjusting block, the rear end outer side of the threaded rod is fixedly connected to the inner side of the bearing, and the outer side of the threaded rod is threadedly connected to the inner side of the threaded hole. When the output shaft of the starter motor rotates to drive the threaded rod to rotate, the completed adjusting block can be driven to slide along the outer side of the limit rod, and the welding head at the lower end can be driven to move to different welding positions for welding.

[0015] A further improvement is that a rubber pad is fixedly connected to the end of the outer side of the arc-shaped sealing plate away from the sliding plate. Therefore, after the two arc-shaped sealing plates at the front end of the outer arc-shaped plate are relatively fixed, the rubber pad at the end of the arc-shaped sealing plate away from the sliding plate contacts each other, so that the contact point of the two arc-shaped sealing plates remains sealed, preventing harmful fumes generated during welding from seeping out from the contact point of the arc-shaped sealing plates.

[0016] In summary, the present application discloses a metal mesh welding and forming machine.

[0017] This technical solution pulls the arc-shaped sealing plates at the left and right ends to make them slide into contact, and at the same time, the left end of the connecting plate slides to the inner side of the connecting frame, and then the plug rod is pushed down by the spring rebound, so that the lower end of the plug rod moves to the insertion hole at the lower end of the connecting frame, and the left end of the connecting plate can be fixed to the inner side of the connecting frame, so that the arc-shaped sealing plate is fixed to the front end of the outer arc plate and the inner arc plate, forming a closed welding space, so that the smoke generated during welding can only be discharged from the exhaust pipe at the upper end, and is filtered and purified by the activated carbon filter and HEPA filter when discharged, and will not cause harm to the surrounding staff.

[0018] Furthermore, by starting the motor and rotating its output shaft to drive the threaded rod to rotate, the completed adjustment block can be driven to slide along the outer side of the limit rod, driving the welding head at the lower end to move to different welding positions for welding work.
