Abstract
The utility model relates to a die bending insert for circuit board busbar. The die bending insert for the circuit board busbar comprises a punch insert and a die insert. The punch insert comprises a lifting block and a punch, the lifting block is arranged with a convex template through a spring, punches which can achieve upper and lower relative displacement with the lifting block are arranged at two sides of the lifting block in a sliding mode, the punches are fixedly arranged with the convex template, the die insert is fixedly arranged on a die template which is right below the bottom portion of the lifting block, the die insert is a top tight long strip with its upper surface as the level surface, the bottom portion of the lifting block corresponds to the middle portion of a circuit board busbar plane work piece, and the punches correspond to the portions to be bended at two sides of the circuit board busbar plane work piece. According to the die bending insert for the circuit board busbar, the punch insert and the work piece circuit board busbar central plane are compressed and positioned through the die insert and the lifting block, and the punch stampings downward two sides of the circuit board busbar plane work piece to form a bend, so that warping upward at the middle of the busbar after being bended is avoided and the difficulty in taking off the work piece is avoided.
Description
Technical field
The utility model belongs to circuit board accessory field, especially a kind of mould bending mold insert for circuit board bus-bar.
Background technology
Circuit board bus-bar is the workpiece that a cross sectional shape is " U " shape, and in the time of machine-shaping, comprising needs has bending operation, in bending operation, conventionally with punch mold insert and die mold insert, circuit board bus-bar flat work pieces is carried out to bending and molding.When bending, the circuit board bus-bar flat work pieces for the treatment of bending is placed on die mold insert, punch mold insert is pressed from the top down, after bending, bus-bar middle part is stayed on die mold insert, after bus-bar both sides downward bending and bending, lay respectively at die mold insert both sides, then by hand the bus-bar after bending is taken off from die mold insert.
But, using above-mentioned bending and molding structure punch mold insert middle part indent used, so punch mold insert both sides first contact with circuit board bus-bar flat work pieces than middle in the time of bending, after bending, in the middle of bus-bar, can tilt upward thus, cause bending not reach requirement.
On the other hand, after bending, after the downward bending of bus-bar both sides, scratch to interior, be buckled on die mold insert, very difficult while taking off, and easily bus-bar is scratched while therefore taking off, its bad order caused, more seriously, also very difficultly in the time assembling with electrical appliance kit main body even cannot pack into, articulate the phenomenons such as bad even if pack into also to there will be, affect electrical appliance kit overall performance.
Utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of mould bending mold insert for circuit board bus-bar simple in structure, reasonable in design is provided.
The technical scheme that the utility model adopts is for achieving the above object:
A kind of mould bending mold insert for circuit board bus-bar, comprise punch mold insert and die mold insert, punch mold insert comprises lift block, drift, described lift block is installed by spring and convex template, be slidably fitted with and can realize with lift block in lift block both sides, the drift of lower relative displacement, this drift and convex template are fixedly mounted with, on concave template under lift block bottom, be fixed with die mold insert, this die mold insert is that a upper surface is rectangular of holding out against of horizontal plane, lift block bottom is corresponding with circuit board bus-bar flat work pieces middle part, drift treats that with circuit board bus-bar flat work pieces both sides bending part is corresponding.
And, described punch mold insert be positioned at circuit board bus-bar flat work pieces directly over, described die mold insert be positioned at circuit board bus-bar flat work pieces under and with the bottom surface crimping of circuit board bus-bar flat work pieces middle part.
And, described punch mold insert be two groups and lay respectively at circuit board bus-bar flat work pieces anterior with rear portion directly over convex template position on.
The beneficial effects of the utility model are:
Punch mold insert is adapted as three parts by the utility model, lift block both sides, the middle part mirror image drift that is slidably installed respectively, each drift inner side end bottom is shaped with arc-shaped recess, while being convenient to the stressed downward bending in bus-bar both sides, form chamfering, lift block is installed by a spring and convex template, drift and convex template are fixedly mounted with, by die mold insert and lift block, workpiece circuit board bus-bar in-plane is compressed behind location, drift is by the downward punching press in circuit board bus-bar flat work pieces both sides, form bending, after avoiding bending, the middle more difficult situation of taking off of workpiece of can also having avoided the tip-tilted while of bus-bar occurs.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model (omission spring);
Fig. 2 is planar structure schematic diagram of the present utility model;
Fig. 3 is the punch insert structure schematic diagram (omission spring) in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of mould bending mold insert for circuit board bus-bar, comprise punch mold insert and die mold insert 5, punch mold insert comprises lift block 3, drift 2, described lift block is installed by spring 6 and convex template, be slidably fitted with and can realize with lift block in lift block both sides, the drift of lower relative displacement, this drift and convex template are fixedly mounted with, on concave template under lift block bottom, be fixed with die mold insert, this die mold insert is that a upper surface is rectangular of holding out against of horizontal plane, for innovative point of the present utility model is more clearly described, so convex template and die version are omitted in accompanying drawing, punch mold insert be positioned at circuit board bus-bar flat work pieces directly over, die mold insert be positioned at circuit board bus-bar flat work pieces under and with the 1 bottom surface crimping of circuit board bus-bar flat work pieces middle part, lift block bottom is corresponding with circuit board bus-bar flat work pieces middle part, drift treats that with circuit board bus-bar flat work pieces both sides bending part 4 is corresponding.
Punch mold insert be two groups and lay respectively at circuit board bus-bar flat work pieces anterior with rear portion directly over convex template position on.
Operation principle of the present utility model is:
On the lift block of punch mold insert, increase spring, when bending, the lift block of punch mold insert first contacts the drift than punch mold insert with circuit board bus-bar workpiece, when the lift block of punch mold insert and die mold insert are by after circuit board bus-bar Work-sheet pressing, punch mold insert drift just can contact with circuit board bus-bar workpiece with mould motion, after avoiding thus punching press, circuit board bus-bar bending middle part upwarps, circuit board bus-bar both sides downward bending part also can not be buckled on die mold insert, is convenient to also take out after bending.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: not departing from the spirit and scope of the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
