When the shearing device is used, the driving device directly drives the blade on the movable blade holder to move towards the blade on the static blade holder and shear the work between the blades, so that the structural assembly of the shearing device is greatly simplified, and the production cost of the shearing device is effectively reduced.
Preferably, the driving device comprises a gear, a rack and a handle, the gear is rotatably connected with the end of the movable cutter holder, the handle is fixedly connected with the gear and extends along the radial direction of the gear, the rack is fixedly connected with the rack, and the rack and the gear are meshed with each other. The rack is arranged in a circular arc shape along the length direction of the rack, and the rack is fixed at the end part above the opening of the rack. The gear is driven to rotate through the handle, meanwhile, the gear rolls along the cambered surface of the rack, and then the movable cutter holder is used to rotate relative to the rack, namely, the blade positioned on the movable cutter holder is driven to move towards the blade positioned on the static cutter holder.
Preferably, the blades on the static blade seat and the movable blade seat are detachably connected, and the detachable blades facilitate the replacement of the blades or the maintenance of the blades when the shearing device is used.
The technical effects of the utility model mainly embody in following aspect: because the movable cutter holder and the static cutter holder matched with the movable cutter holder are arranged on the rack, when the shearing device is used, the blade on the movable cutter holder is directly driven by the driving device to move towards the blade on the static cutter holder, so that the work between the blades can be sheared, the structural assembly of the shearing device is simplified, and the production cost of the shearing device is effectively reduced.
Drawings
Fig. 1 is a schematic structural diagram of a manual shearing apparatus of the present invention.
Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master.
In the present embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "left end", "above", "back", "middle", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description of the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In addition, in the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin fixing manner, a welding fixing manner, or a hollow rotating shaft connection manner, which is commonly used in the prior art, and therefore, the detailed description thereof is omitted in this embodiment.
As shown in fig. 1, the embodiment provides a manual shearing apparatus, which comprises a frame 1, one side of frame 1 is the opening setting, frame 1 open-ended below is provided with quiet blade holder 2, quiet blade holder 2 and frame 1 integrated into one piece, quiet blade holder 2 is the perpendicular setting, the top of quiet blade holder 2 is provided with moves blade holder 3, it is used for shearing the blade 4 of work piece to be provided with mutually supporting respectively on blade holder 3 and the quiet blade holder 2, the edge of a knife of blade 4 is relative setting, it forms the rotation with frame 1 through the round pin axle to form along its length direction one end on the blade holder 3 and is connected, the other end of moving blade holder 3 is provided with drive arrangement 5, drive arrangement 5 is used for driving and moves blade holder 3 to the motion of quiet blade holder 2 direction. When the shearing device is used, the driving device 5 directly drives the blade 4 on the movable cutter holder 3 to move towards the blade 4 on the static cutter holder 2, and the work between the blades 4 is sheared, so that the structural assembly of the shearing device is greatly simplified, and the production cost of the shearing device is effectively reduced.
As shown in fig. 1, in a preferred embodiment, the driving device 5 includes a gear 51, a rack 52 and a handle 53, the gear 51 is rotatably connected with the end of the movable blade holder 3 through a pin, the handle 53 is fixed with the gear 51 through a bolt or welding, the end of the handle 53 extends in the radial direction of the gear 53, the rack 52 is fixed with the frame 1 through a bolt, and the rack 52 is meshed with the gear 51.
