Abstract
The invention discloses a steel plate bending device for bones. The steel plate bending device for the bones comprises a base, wherein a pair of supporting columns are arranged on the base in a spaced mode, a clamping block is arranged on each supporting column, a clamping groove allowing a steel plate to be clamped in is formed in each clamping block, a lifting pressure head pressed on the central portion of the steel plate is arranged at the middle position between the supporting columns, and a head of the lifting pressure head is arc. The steel plate bending device for the bones is simple in structure and convenient to operate, bending of the steel plate is achieved through the lifting and falling of the lifting pressure head, and the bending accuracy and the operation safety of the steel plate are improved.
Description
Technical field
The present invention relates to a kind of bone steel plate bending device.
Background technology
In orthopaedics therapy, multiplex steel plate is fixed injury of the bone place, and because each position of skeleton is different, flexibility is different, therefore need to steel plate, carry out bending according to instructions for use, with the skeleton of fitting better, reaches perfect fixed effect.Two bending plates with draw-in groove of general use during current steel plate bending, steel plate both sides are snapped in respectively in draw-in groove, by manpower, hold bending plate steel plate is carried out to bending, until reach the flexibility needing, this mode, waste time and energy, crooked precision is not high, and careless steel plate easily ejects draw-in groove and operator is damaged.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency of prior art, a kind of easy to operate, bone steel plate bending device that can improve crooked precision and processing safety is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of bone steel plate bending device, there is base, on described base, be provided with pair of posts apart, described pillar is provided with clamp, on described clamp, have the draw-in groove snapping in for steel plate, centre position between described pillar is provided with the lifting pressure head that is pressed in steel plate central part, and buck head portion is arc.
For realizing lifting pressure head, do elevating movement, between described pillar upper end, be connected with fixed bar, in the middle of fixed bar, be provided with feed screw nut, be connected with the screw mandrel being threaded with feed screw nut on lifting pressure head, screw mandrel upper end is provided with handwheel.
For clamping better steel plate, described clamp is provided with the pinching screw of vertical clamping steel plate.
For meeting more width steel plate user demands, one described, pillar is fixed on base, and another pillar slides to be located on base and relatively moves.
The invention has the beneficial effects as follows: the present invention is simple in structure, easy to operate, the lifting by lifting pressure head realizes steel plate bending, has improved crooked precision and the processing safety of steel plate.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
In figure: 1. base, 2. pillar, 3. clamp, 4. draw-in groove, 5. lifting pressure head, 6. fixed bar, 7. feed screw nut, 8. screw mandrel, 9. handwheel, 10. pinching screw.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
A kind of bone steel plate bending device as shown in Figure 1, have base 1, described base 1 is provided with pair of posts 2, and 2 one described, pillar is fixed on base 1, another pillar 2 slides to be located on base 1 and relatively moves, and can meet like this user demand of more width steel plates.
Described pillar 2 is provided with clamp 3, on described clamp 3, have the draw-in groove 4 snapping in for steel plate, on clamp 3, be positioned at the pinching screw 10 that draw-in groove 4 places are provided with vertical clamping steel plate, to clamp better steel plate, centre position between described pillar 2 is provided with the lifting pressure head 5 that is pressed in steel plate central part, and lifting pressure head 5 heads are arc.
For realizing lifting pressure head 5, do elevating movement, between described pillar 2 upper ends, be connected with fixed bar 6, in the middle of fixed bar 6, be provided with feed screw nut 7, be connected with the screw mandrel 8 being threaded with feed screw nut 7 on lifting pressure head 5, screw mandrel 8 upper ends are provided with handwheel 9.
When the present invention uses, according to steel plate width, regulate distance between two pillars 2, the steel plate both sides that need bending are snapped in respectively in the draw-in groove 4 of clamp 3, tighten pinching screw 10, rotate handwheel 9, by rotatablely moving between screw mandrel 8 and feed screw nut 7, drive lifting pressure head 5 to decline and be pressed in steel plate central authorities, be rotated further handwheel 9, make steel plate progressively crooked, until instrument for steel plate bending degree meets the requirements.
The present invention is simple in structure, easy to operate, and the lifting by lifting pressure head 5 realizes steel plate bending, has improved crooked precision and the processing safety of steel plate.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content in description, must determine its technical scope according to claim scope.
