Technical field
The utility model relates to Machining Technology field, particularly a kind of v-shaped bending mould and V-arrangement punch press.
Background technology
Crooked part is one of punching parts that during Modern Industry Products, automobile, electrical equipment, instrument and instrument are manufactured, quantity is maximum, its principal mode has: V-arrangement, U-shaped, Z-shaped, crimp and other complex-shaped parts, crooked part major part is to adopt bending mould to be shaped.Existing bending mould comprises punch and die, and punch is descending under the drive of forcing press, and workpiece, under the acting in conjunction of die and punch, completes bending forming.Tradition Bending Mould easily causes product surface impression aborning, is not suitable for the stricter product of appearance requirement.When product bending angle changes, need overhaul mould, maintenance difficulty is larger.When material is thicker, lower cavity die easily ruptures, and has increased mold repair cost.
There is at present movable matrix V-arrangement Bending Mould, by V-arrangement mould Die Design, be mobilizable, see Chinese patent CN202934024U, movable V-arrangement mould is hinged by rotating shaft and support, rotating shaft is support slip relatively vertically, this kind of design needs mounting bracket, rotating shaft, and processing, maintenance cost increase.
Separately there is Chinese patent CN203076433U, adopt the turnover panel connecting by axle to realize the scheme of movable matrix.The axial region of this kind of scheme connection is divided into main stressed member, acts frequently, and easily causes axle strain, and maintenance cost is high, and quality is unstable.
Two schemes is two portable plates that axle connects die, and by rotating shaft, the portable plate of die is connected, and rotate and realize die activity with axle, and the design of two schemes, rotating shaft is mainly stressed, movable easily worn part, maintenance cycle is short, increases maintenance cost.
Utility model content
For overcoming the shortcoming of the movable Bending Mould of above-mentioned existing V-arrangement, the utility model provides a kind of movable centering block v-shaped bending mould and punch press, improves product surface quality, reduces and produce and maintenance cost.
For achieving the above object, the utility model has adopted following technical scheme:
Movable centering block v-shaped bending mould of the present utility model, comprise upper bolster, punch, die shoe and movable matrix, upper bolster lower surface is provided with punch, lower bolster is installed on die shoe, arrange movable matrix corresponding to punch on lower bolster, described movable matrix comprises block and swinging block, block is detachably arranged on lower bolster by bolt etc., block has the hypotenuse that same punch angle is identical, and swinging block is articulated with on block.
Perfect as to such scheme, movable centering block v-shaped bending mould of the present utility model, also comprises push rod, and itself and swinging block lower surface are conflicted, and die shoe moves up and down relatively.
Meanwhile, the resistance surface that swinging block and push rod is set is smooth periphery.
Further, also comprise lower roof plate and spring, push rod is arranged on lower roof plate, and spring fitting is below lower roof plate.
As preferably, can limited block be set in addition, be arranged on die shoe upper ejector pin outside, conflict with swinging block lower surface.
The utility model also relates to a kind of punch press that movable centering block v-shaped bending mould as above is installed, it also comprises bottom seat pad, bottom deck and outer guiding post, bottom deck is arranged on spring bottom, and bottom seat pad is arranged between die shoe and bottom deck, and outer guiding post is arranged between upper bolster and die shoe.
Compared with prior art, the beneficial effects of the utility model are:
1) movable matrix comprises block and swinging block, and during mold open state, swinging block and block are in same level, along with punch declines, swinging block inwardly rotates along hinged place, when swinging block rotates to punch angle, plate contacts with the inclined edge surfaces of block simultaneously, and plate stops bending.In Forging Process, plate is progressively crooked with swinging block, improves the situation of drawing trace, solves plate scratch, draws trace, abrasive situation, improves the wear condition of mould.
2) by setting the angle of the angle of punch and the spacing hypotenuse of block, realize the bending of different angles plate, when bending angle changes, can select or overhaul the bending of punch and the plate that block completes differently curved angle of different angles, mold repair, overhaul conveniently, cost is low.
3) swinging block rotates to the inside with the trailing edge hinged place of punch, the power declining to the dispersed punch of hinged place, both sides rotating shaft, compare with the situation of rotating shaft below in the middle of two swinging blocks, impact to hinged rotating shaft reduces, extend the service life of mould, reduce costs and maintenance cost, and punching press plate each several part is stressed evenly, improves workpiece quality and die life.
4) automatic ejecting mechanisms such as push rod, spring are set, complete the folding of workpiece complete after, after punch lifts, by push rod, swinging block and workpiece are ejected, mould, again in opening, completes ejecting without manual intervention automatically, easy to operate; And push rod contacts with swinging block lower surface is round and smooth, alleviates the wearing and tearing of push rod and swinging block, extend die life, reduce maintenance cost.Meanwhile, push rod, with the downward impulsive force of hinged place rotating shaft shared punch, alleviates the impact to hinged place rotating shaft, extends die life.
5) between swinging block and die shoe, limited block is set, when swinging block is rocked to bending angle, plate is subject to block hypotenuse and limits no longer bending; Swinging block arrives limited block simultaneously, contacts with limited block, and limited block restriction swinging block continues rotation.It is downward that limited block only stops punch jointly with block, bears the downward impact of punch simultaneously, extends the service life of mold integral, improves service efficiency, reduces maintenance cost.
