Description
Technical field
The present invention relates to a kind of process unit by electric wire single use deflectable molding, specifically a kind of cable is curved
Line tweezer.
Background technology
The electric wire that electrical equipment commonly uses is it is generally required to bending machining, and the past, usual manual bending completed, curved
Bent radian and size are difficult to ensure that machining accuracy, directly affects installation quality, also affect product appearance quality simultaneously；Tradition
Processing mode, not only make processing staff's labor intensity can not get alleviating, and inefficiency, current all trades and professions high-tech
Develop rapidly, seek to make conductive line bends molding standardization, rapid modern manufacturing process particularly reality with urgent.
On 05 15th, 2013, China utility model Authorization Notice No. CN 202934054U disclosed a kind of bending pliers, bag
Include up knob, lower handle, upper jaw, lower jaw and rotating shaft, described up knob and lower handle and connect fixing by rotating shaft, described on
Jaw is connected with lower handle, is provided with a projection inside upper jaw；Described lower jaw is connected with up knob, sets inside lower jaw
Being equipped with V-type groove, the knuckle of described V-type groove is right angle, the setting corresponding with V-type groove of described projection.This patent in order to
Reduce the labor intensity of operator, utilize the operation principle of lever, be designed as pushing, the structure that pincers limit is short, but this structure
Owing to pincers limit is short, jaw is the least away from rotating shaft, and when the wire that jaw bend diameter is bigger, the subtended angle clamping limit up and down becomes relatively
Greatly, during pressure down, jaw inner bulge acts on the position of putting forth effort of wire and constantly changes with the change of subtended angle；And V-type is recessed
Groove has stop limit effect to electric wire, and cable cannot rotate；Then jaw inner bulge creates rotary-cut effect, and result makes
Cable insulation layer is impaired, has a strong impact on the quality of product.
Summary of the invention
It is an object of the invention to provide a kind of cable bending pliers, make the disposable standard forming of cable, cable not damaged, work
Make efficiency high.
The present invention is to realize by the following technical solutions:
A kind of cable bending pliers, including upper lever, middle lever, lower lever；Upper lever be the steel bar of two " V " word shapes also
Row's combination, the right flank limit of two " V " word shape steel bars is superimposed and forms operation up knob；With double rivets clamping in the middle part of left wing limit
The upper end of short connecting rod, the upper end of the first bearing pin long connecting rod of rivet activity clamping connection one, end, left wing limit；
Described middle lever is that two plate shapes are the same, has the deformed steel flats Side by side groupings divided of concentric reducer；Two deformed steel flats
Major part end relatively has axis hole；In the middle part of two deformed steel flats, the big inner side in front of deflection, lives with the second bearing pin rivet
The lower end of the dynamic above-mentioned short connecting rod of clamping connection；Shaping mould on two deformed steel flats little cephalic par clamping connection one；It is provided with one on upper shaping mould
The location adjusting rod of adjustable stroke；
Described lower lever be two panels one be head elongated, another be the long steel plate Side by side groupings that there is lug at splitter shape, middle part, two
The splitter shape end of long steel plate is superimposed and forms the lower handle of operation；The elongated end inside parallel clamping die-cushion plate once of two long steel plates,
Both sides, outside are fixed with a pair time mould holder with bolt respectively, and the upper end of every pair of lower mould holder is provided with a compacted under mould；
The stub end of described middle lever is clamped by lug in the middle part of two long steel plates, and with the 3rd bearing pin rivet and back-moving spring by long steel
The lug of plate is the most hinged with the stub end of middle lever；
After the middle part of described long connecting rod passes two deformed steel flats inside middle portion spaces of middle lever, lower end and lower lever
By the 4th bearing pin rivet activity clamping connection between two long steel plate elongate section inside middle portion.
2.5m is had on described compacted under mould2、4 m2、6 m2、10m2、16 m2With 25 m2Electric wire or cable bending mouth；
The stub end place of being movably hinged of described middle lever also sets conductive line bends angle index and indicates.
Compared with prior art, the invention have the benefit that
1) present invention make use of the upper lever of floating and middle lever mated dexterously, middle lever and lower lever arm of force is prolonged
Long, the jaw making the present invention is long away from pivot design relatively prior art, and the jaw bend diameter formed when upper and lower shaping mould is bigger
During wire, the subtended angle that the lever segment up and down on pincers limit is formed up and down is the most little, during pressure down, and upper shaping mould effect in jaw
Although constantly changing with the change of subtended angle in the position of putting forth effort of wire；But change the least；Meanwhile, the present invention have distinctive by under
A pair compacted under mould that mould holder supports can coordinate in relative rotation so that cable insulation layer is almost malleation, does not produce rotation
Cut impaired, it is ensured that affect the quality of product；
2) the pressure stroke down of lever during the present invention can be adjusted by location adjusting rod, in cooperation, the stub end of lever is movable
The conductive line bends angle index of hinged place indicates and different size electric wire or cable bending mouth on compacted under mould；Difference can be made
The conductive line bends of specification becomes satisfactory angle, molding standard of the present invention, quickly, and repeatedly uses, and molding is consistent, has
Improve crudy to effect.
