Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal flipping and positioning, in particular to a sheet metal flipping device for processing armored entrance doors. Background Technique

[0002] An armored entrance door is a type of door product that combines steel and wood. Its structure is mainly composed of a mixture of steel and wood. When producing an armored entrance door, it is necessary to cut the internal sheet metal.

[0003] The Chinese patent discloses an angle flipping device for sheet metal surface processing, with the publication number CN215281870U, which includes a processing table and a driving motor. Above the middle of the processing table, a bearing plate is rotatably installed. A rotating plate is arranged on the right side of the bearing plate. An active block is arranged in parallel on the outside of the rotating plate. A toggle rod perpendicular to the active block is connected to the rotating plate. An inverted V-shaped groove is arranged on the end face of the active block facing the rotating plate. The end of the toggle rod is slidably inserted into the inverted V-shaped groove. A driving mechanism for driving the parallel movement of the active block is also installed on the workbench. By moving the active block, the toggle rod slides to different positions in the V-shaped groove, realizing the reliable flipping of the bearing plate.

[0004] However, it still has the following disadvantages: The device is on the bearing plate. By using the through holes opened on the bearing plate, it is convenient to process the upper and lower end faces of the sheet metal. However, since the bearing plate is hollow inside, there is no support in the middle of the sheet metal. When the middle part of the sheet metal is stressed during processing, it is prone to large deformation. For this reason, we propose a sheet metal flipping device for processing armored entrance doors to solve this problem. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sheet metal flipping device for processing armored entrance doors to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A sheet metal flipping device for processing armored entrance doors, including a mounting frame, a positioning device is arranged inside the mounting frame, and the positioning device includes a positioning part;

[0007] The positioning part includes a limiting plate, a limiting slider and a limiting rod. A sliding groove is opened on the front surface of the limiting plate. The outer surface of the rear end of the limiting rod extends into the limiting plate and is slidably connected to the inner wall of the limiting plate. The rear end of the limiting plate is hinged to the top surface of the rear limiting slider;

[0008] A flipping part is arranged inside the mounting frame;

[0009] The flipping part includes a motor, a rotating shaft, a baffle plate and a clamping rod. The bottom surface of the motor is fixedly connected to the top surface of the mounting frame. The outer surface of the rotating shaft is fixedly connected to the outer surface of the flipping frame. The outer surface of the rotating shaft passes through the inner wall of the mounting frame through a bearing and extends to the outside of the mounting frame. The back surface of the baffle plate is fixedly connected to the front surface of the clamping rod. Slots are formed on both the front and back surfaces of the flipping frame. The outer surface of the rear end of the clamping rod slidably passes through the front surface of the mounting frame and extends into the slot.

[0010] Further improvement lies in that the positioning part further includes a flipping frame, an extrusion plate, a screw rod, a second spring and a return frame. The outer surface of the screw rod threadedly passes through the outer surface of the limiting plate and extends into the flipping frame. The outer surface of the screw rod is rotatably connected to the outer surface of the extrusion plate through a bearing seat. By setting the screw rod and the extrusion plate, by rotating the screw rod, the extrusion plate can extrude and limit the sheet metal.

[0011] Further improvement lies in that a limiting chute is formed on the outer surface of the flipping frame. The outer surface of the limiting slider extends into the limiting chute and is slidably connected to the inner wall of the limiting chute. By setting the limiting slider, it is convenient to control the left and right movement of the limiting plate, the limiting rod and the extrusion plate, so that the extrusion plate supports the middle part of the sheet metal, reduces the deformation of the sheet metal, and at the same time avoids the extrusion plate from the sheet metal processing position.

[0012] Further improvement lies in that the return frame is slidably sleeved on the outer surface of the limiting rod. The outer surface of the return frame is fixedly connected to the outer surface of the front limiting slider. By setting the return frame, the limiting plate and the limiting rod, by rotating the upper limiting plate and the limiting rod, the sheet metal can be placed between the upper and lower limiting plates, which is convenient for the installation and disassembly of the sheet metal.

[0013] Further improvement lies in that the front end of the second spring is fixedly connected to the back surface of the limiting rod. The rear end of the second spring is fixedly connected to the inner wall of the limiting plate. By setting the second spring, it is convenient to position the limiting rod. By pushing the limiting rod backward, it is convenient to make the return frame no longer limit the limiting rod.

[0014] Further improvement lies in that the flipping part further includes a first gear, a second gear and a first spring. The first gear is fixedly sleeved on the outer surface of the output shaft of the motor. The second gear is fixedly sleeved on the outer surface of the right rotating shaft. The outer surface of the first gear is meshed with the outer surface of the second gear. By setting the motor, the first gear, the second gear and the rotating shaft, starting the motor can drive the rotating shaft and the flipping frame to rotate, which is convenient for flipping the sheet metal.

[0015] Further improvement lies in that the front end of the first spring is fixedly connected to the back surface of the baffle plate. The rear end of the first spring is fixedly connected to the front surface of the mounting frame. By setting the first spring, the clamping rod and the baffle plate, using the pulling force of the first spring, the clamping rod positions the flipping frame, making the sheet metal more stable.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: For the sheet metal flipping device used in the processing of the armored entrance door, by setting a flipping frame, a pressing plate, a limiting plate, a screw rod, a limiting slider, a second spring, a limiting rod, and a looped frame, the elastic force of the second spring is utilized to position the limiting rod and the limiting plate, facilitating the placement of the sheet metal inside the upper and lower limiting plates. Rotate the screw rod to make the pressing plate limit the sheet metal and support the middle part of the sheet metal. By moving the limiting slider left and right, the position of the pressing plate is changed to avoid the sheet metal processing position; by setting a motor, a first gear, a second gear, and a rotating shaft, start the motor, and utilize the first gear and the second gear to drive the rotating shaft to rotate, so that the flipping frame and the sheet metal flip together; by setting a first spring, a baffle, and a clamping rod, the pulling force of the first spring is utilized to limit the flipping frame and position the sheet metal.
