Abstract
The utility model discloses a metal sheet bending and sealing device consisting of a shell, a clamp mechanism and a clamp driving mechanism in the shell. The clamp mechanism includes a pair of strip shaped clamps and a rotary shaft which arranges the clamps inside the shell and is used as a pivot for the clamps to rotate. The lower ends of the clamps extend out of the shell. The clamp driving mechanism is provided with a main shaft and a non-central component which is arranged on the main shaft and connected with the upper ends of the clamps. One end of the main shaft is arranged inside a mounting hole of the shell and connected with the exterior rotary power source via the mounting hole. With simple structure and small size, various electric and pneumatic tools can be chosen as the power source for the utility model. Under the periodical clamping and fastening effect formed between the two clamps, the joint of the metal sheet is bended and sealed, and the work efficiency is improved.
Description
Technical field
The utility model relates to the metal machining tool, relates in particular to a kind of metal sheet bending closing device.
Background technology
In the processing technology of metal sheet goods, two sheet materials connections are normally sealed in lap-joint's bending, for the fixed product of producing in batches, this operation is finished by special equipment and mold; And for scattered processing and site operation, then with manual way of beaing, inefficiency.
Summary of the invention
It is a kind of by the general dynamic source that the purpose of this utility model is to provide, and assists the manual device that the metal sheet bending is sealed that carries out.
For achieving the above object, the technical solution of the utility model is: a kind of metal sheet bending closing device is characterized in that: this device comprises housing and is arranged at housing interior clamping mechanism and clamp drive mechanism; Described clamping mechanism comprises a pair of bar shaped chela and chela is installed in the housing and as the rotating shaft of chela swing fulcrum, the lower end edge of chela reaches outside the housing; Described clamp drive mechanism is made of main shaft and the offset assembly that is arranged on the main shaft, and offset assembly is connected with the upper end of chela, and the end of main shaft is arranged in the installing hole on the housing and by installing hole and is connected with outside rotating power source.
In the said structure, offset assembly on the clamp drive mechanism main shaft is connected with the upper end of chela, when main axis rotation, offset assembly promotes the upper end of two chelas, with the rotating shaft is fulcrum, forming periodic clamping action along between the chela lower end that reaches outside the housing, during construction, metal sheet overlap joint with machine-shaping, and adopt this device in lap-joint, and finish bending and seal, improve efficiency of construction, and this apparatus structure is simple, small and exquisite, and used power source can extensively be chosen various electronic, air tool power sources.
