Description

Technical Field

[0001] The present application relates to the technical field of metal sheet processing, and in particular to a clamping device of a metal sheet bending machine. Background Art

[0002] Sheets are flat rectangular building material panels made into standard sizes and used in the construction industry as components of walls, ceilings or floors. They also refer to metal sheets that are forged, rolled or cast. When bending metal sheets, it may be necessary to bend them. When bending metal sheets, a bending machine is required.

[0003] At present, when the relevant metal sheet bending machines are used, due to the lack of a clamping mechanism with a feeding function, workers are required to hold the metal sheets for auxiliary bending processing, which is time-consuming and manpower-consuming, and it is not easy to perform feeding operations, affecting the metal sheet processing efficiency. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the present application provides a clamping device for a metal sheet bending machine.

[0005] The clamping device of a metal sheet bending machine provided in the present application adopts the following technical solution:

[0006] A clamping device for a metal sheet bending machine comprises a fixed plate, a lower clamping plate and an upper wheel frame, one end of the fixed plate is fixedly connected to a connecting plate, the top of the connecting plate is fixedly connected to an electric push rod, the top of the fixed plate is movably mounted with a lower clamping plate, a movable rod is installed between the lower clamping plate and the fixed plate, the lower wheel frame is movably mounted inside the fixed plate, a threaded rod is movably mounted on one side of the top of the lower clamping plate, an upper clamping plate is movably mounted on the periphery of the threaded rod, one side of the upper clamping plate is fixedly connected to a motor, and the upper wheel frame is installed on one side of the motor inside the upper clamping plate.

[0007] By placing the metal sheet between the upper wheel frame and the lower wheel frame, and by screwing the threaded rod, the upper clamping plate drives the upper wheel frame to descend until it contacts the metal sheet, and the upper wheel frame and the lower wheel frame cooperate to clamp the metal sheet, and the upper wheel frame is driven to rotate by the motor, so that the upper wheel frame and the lower wheel frame cooperate to transfer the metal sheet to the inside of the external bending machine, and then the metal sheet is bent by the external bending machine. When the bending machine bends the metal sheet, the upper clamping plate and the lower clamping plate are synchronously lifted up with the workpiece, and the electric push rod can also be controlled to synchronously lift the lower clamping plate according to the bending degree of the bending machine, so as to clamp and fix the metal sheet without affecting the angle change of the metal sheet when bending.

[0008] Preferably, a rotating disk is fixedly connected to the top of the threaded rod, and a handle is movably mounted on the top of the rotating disk.

[0009] The rotating disk is rotated by holding the handle, so that the rotating disk drives the threaded rod to rotate. The handle increases the contact area and friction between the palm of the worker and the rotating disk, making it easier for the worker to rotate the threaded rod.

[0010] Preferably, a limiting rod is fixedly connected to the other side of the top of the lower clamping plate, and the limiting rod passes through the upper clamping plate.

[0011] The limit rod can guide and limit the movement direction of the upper splint, thereby improving the stability of the movement of the upper splint.

[0012] Preferably, a fixing frame is fixedly connected to the outer side of the fixing plate, and a bolt hole is provided inside the fixing frame.

[0013] The device can be fixedly installed on the external bending machine by connecting the fixing frame to the external bending machine structure and then screwing the external fixing bolts between the bending machine structure and the fixing frame and passing through the bolt holes.

[0014] Preferably, a fixing piece is fixedly connected between the connecting plate and the fixing plate, and a bolt is movably installed between the fixing piece and the fixing plate.

[0015] The contact area between the connecting plate and the fixing plate is increased by the fixing piece, and the fixing piece and the fixing plate are fixed by bolts, thereby improving the stability of the connecting plate installation.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] By twisting the threaded rod, the upper wheel frame and the lower wheel frame cooperate to clamp the metal sheet, and the upper wheel frame is driven to rotate by the motor, so that the upper wheel frame and the lower wheel frame cooperate to transport the metal sheet to the outside of the bending machine. When the bending machine bends the metal sheet, the upper clamping plate and the lower clamping plate are synchronously lifted up with the workpiece, and the electric push rod can also be controlled to synchronously lift the lower clamping plate with the bending degree of the bending machine to clamp and fix the metal sheet without affecting the angle change of the metal sheet during bending, ensuring that the metal sheet can be bent normally, and can assist in feeding, saving manpower and time, and improving processing efficiency.
