Description
Technical field
The utility model relates to a kind of Portable steel-wire bending devices.
Background technique
Steel wire will pass through certain treatment process before carrying out physical property inspection, wherein just including the work for bending steel wire
Sequence.Steel wire bending device is exactly the equipment for bending steel wire, and Portable steel-wire bending device is then that a kind of structure is simple, is convenient for
The light instrument of carrying is suitable for small-scale artificial bending use occasion.
Existing Portable steel-wire bending device is as shown in Figure 1, Figure 2 and Figure 3, including lower stripe board 1, upper stripe board 2, rotation
Bolt 3 and bending bolt 4, one end of lower stripe board 1 and one end of upper stripe board 2 are overlapped and pass through the rotation rotation connection of bolt 3,
The lower section 34 for rotating the stud of bolt 3 is equipped with screw thread and one end after the through-hole of one end of upper stripe board 2 with lower stripe board 1
Screw hole be fixedly connected, the upper section 33 of stud for rotating bolt 3 is preferably no screw thread, to reduce upper stripe board 2 relative to lower item
Frictional force when shape plate 1 rotates, the upper end of rotation bolt 3 are nut 32, and the upper middle position for rotating the nut 32 of bolt 3 is set
There is strip groove 31, rotating the periphery of the nut 32 of bolt 3 is round in order to steel wire bending, rotates the nut 32 of bolt 3
Central upper portion position is additionally provided with the hexagon counterbore of sinking, in order to be used cooperatively with outer hexagonal spanner；It is close in upper stripe board 2
Rotation bolt 3 position be equipped with bending bolt 4, bend bolt 4 stud lower section 43 be equipped with screw thread and in upper stripe board 2
The screw hole of corresponding position is fixedly connected, and the upper section 42 for bending the stud of bolt 4 does not have screw thread, bends the week of the nut 41 of bolt 4
Side is hexagon in order to be used cooperatively with allen wrench, and the central upper portion position for bending the nut 41 of bolt 4 is additionally provided with down
Heavy hexagon counterbore, in order to be used cooperatively with outer hexagonal spanner.As shown in Figure 4 and Figure 5, in use, steel wire 5 from top to bottom
Be placed in the strip groove 31 of rotation bolt 3, by rotate upper stripe board 2 can make to bend bolt 4 be placed in steel wire 5 left side or
Right side, and steel wire 5 is made to be placed in the lower section for bending the nut 41 of bolt 4 so that steel wire 5 is limited in the process of bending, such as Fig. 4 institute
