Specific embodiment
It should be noted that the feature in embodiment and embodiment in the case where not colliding, in the invention
It can be combined with each other.
Detailed description of specific embodiments of the invention is provided below.
A kind of high-precision steel plate bending mold, as shown in Figures 1 to 3, including the upper die holder 1 and lower die holder 2 being correspondingly arranged；
It is equipped with work top 3 on the upside of the lower die holder, mounting groove is equipped on work top, cavity plate 4, cavity plate are installed in the mounting groove
Upper surface and work top can be in same plane；Cavity plate is corresponded on the upper die holder, punch-pin 5 is installed, in upper die holder
Outside correspond to lower die holder work top be equipped with pressing device 6；The pressing device includes pedestal 7, to the pressure below pedestal
Several hold-down mechanisms between plate 8 and pedestal and pressing plate.Cavity plate and punch-pin are all made of hard alloy production.
It should be noted that hold-down mechanism can be disposed side by side on upper die holder towards the side of steel plate supplied materials because of the other side
The fixation of progress steel plate is not needed, steel plate is only extend into above cavity plate from the side of supplied materials, by the pushing of punch-pin, to bend steel
Plate.
In an alternative embodiment, in order to ensure steel plate can accurate bending, fed in mounting groove different from steel plate
Side is equipped with position block 9, and the work top is equipped with two slideways perpendicular to mounting groove, is equipped with sliding block on slideway
10, the block is mounted on sliding block.In general, slideway can use T shape slot or dovetail groove, both ensure that when sliding block slides
Position precision, meanwhile, position-limiting action is also acted as, sliding block and slideway cooperation precision are high, can effectively ensure that sliding block is stable in slideway
Upper sliding.
By adjusting slide position, change position block at a distance from mounting groove, and then realizes that adjustment steel plate 17 is bent over
Crimp width purpose.Specifically, can be set on sliding block to positioning link, when sliding block slides into suitable position, positioning
After stop location meets the requirement of steel plate bending size, sliding block can be fixed on work top by positioning link (can
To be to have location hole in slideway, it is also possible to that location hole is arranged in other positions, as long as realizing the fixation of sliding block).In general,
Positioning link uses screw, and location hole uses threaded hole, screws the screw being arranged on sliding block, sliding block is fixed.
It should be noted that position block extends to above cavity plate towards the side to bending steel plate, because steel plate is by punching press
Downward deformation is completed in cavity plate, if steel plate crosses cavity plate, can not punching press flanging therefore need to guarantee that steel plate waits rolling over
Curved one end edge is in cavity plate.
After the steel plate of bending is set size, the connector for fixing sliding block is unclamped again, position block is removed
Upper die holder vertical direction projects previous position, avoids interfering in punching course.
Above-mentioned punch-pin includes horizontally disposed cylindrical crimp 11, that is, the axial direction of pressure head is horizontally disposed, in pressure head two sides pair
Claim to be equipped with the side wing 12, punch-pin is fixed on by upper die holder by the connector 13 on the wing of side.Above-mentioned pressure head is in the portion on the downside of the wing of side
Divide and is in the part on the upside of the wing of side greater than it.Connector generally uses attachment screw, preferably, for wearing on the wing of side
The via hole of screw is the through-hole with heavy platform, tighten it is fixed after, the nut portion of screw submerges in heavy platform, do not influence punch-pin with it is recessed
The combination of mould.
In an alternative embodiment, in order to reduce the noise generated in punching course, can punch-pin pressure head with it is upper
Acoustical cotton is set in the gap between die holder cavity, meanwhile, (the mounting groove of lower die holder in the gap between cavity plate and lower die holder
Between female bottom) setting acoustical cotton, the noise in punching course can be effectively reduced.
Above-mentioned upper die holder is equipped with groove, which is greater than the height that pressure head top protrudes from the side wing.That is,
The upper part of pressure head can be submerged completely in the groove, guarantee that the side wing of two sides is stably fixed on upper die holder, it is ensured that structure
Between be connected firmly, stability is good.
Above-mentioned hold-down mechanism includes the compression bar 14 being vertically arranged, which connects pressing plate, upper end pass through pedestal and with
Pedestal is slidably matched；The compression bar goes out one end of pedestal and locks by adjusting with nut 15；Bullet is equipped between pressing plate and pedestal
Property part 16.In an alternative embodiment, for above-mentioned elastic component using the pressure spring being sleeved on compression bar, which resists base
Seat, lower end resists pressing plate.
Elastic component has downward active force to pressing plate always, and when punching press acts, pressing plate can be pressed on plate, due to compression bar
Upper end is slidably arranged on pedestal, and therefore, compression bar is slidably matched with pedestal and is moved up when punch-pin continues to fall, elastic component
Elastic force be gradually increased, after the completion of punching press, during punch-pin moves up, in one section of displacement range, pressing plate still can be to steel plate
Undressed part keeps pressed status, and steel plate is avoided to be taken up, even processing to thin plate, does not also easily cause plate in punching press
Deformation in journey effectively increases product qualification rate, and the plate flatness for not being processed part is good, and corner doses is reduced, and reduces
The consumption of steel plate, reduces processing cost.
The invention structure is simple, during carrying out pressing and bending to steel plate, using pressing device always to steel
Plate compresses, and when mold is pushed with backhaul, stability is good, and steel plate will not deform, meanwhile, bending size can according to need tune
Whole, the bending precision of steel plate has obtained reliable guarantee.
It is obvious to a person skilled in the art that the invention is not limited to the details of above-mentioned exemplary embodiment, and
And without departing substantially from the spirit or essential attributes of the invention, wound that the present invention can be realized in other specific forms
It makes.
Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this
The range of innovation and creation is indicated by the appended claims rather than the foregoing description, it is intended that equally wanting for claim will be fallen in
All changes in the meaning and scope of part are included in the invention.Any appended drawing reference in claim should not be regarded
To limit the claims involved.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
