Description
Technical field
The utility model is related to handware stamping areas, and in particular to a kind of half punching diel.
Background technology
Diel is in Cold Press Working, by material（Metal is nonmetallic）It is processed into part（Or semi-finished product）'s
A kind of special process equipment, referred to as cold punching die（It is commonly called as cold-punching mould）.Punching press is at room temperature, using mounted on forcing press
On mold to material apply pressure, make its generate separation or plastic deformation, to obtain needed for part a kind of pressure processing
Method.
It is in the majority with handware diel in diel, it, can by punching press since metal has good ductility
So that it is generated plastic deformation, also because metal has ductility, when punching press detaches, the metal of incision can not be avoided to generate modeling
Property deformation, to form incomplete notch.Especially some hardware planks carry out local punching, to the hardware plank of diecut region
Partial cut is carried out, it is made still to be connect with former hardware plank.There are more problems for the hardware plank being locally punched, due to diecut region
Hardware plank cannot completely cut through, need to control stamping press, notch is easy to happen plastic deformation；To the five of diecut region
Golden plate material needs certain support, if keeping the hardware plank of diecut region completely hanging, the hardware plank of diecut region is excessive after punching
Bending, is unable to control the bending degree of diecut region hardware plank；Support is arranged in existing diel generally below diecut region
Part continues punching press for limiting punch, but punching back punching head can hit support element, cause the hardware plank compressive deformation of the part,
Long-time service is easy to damage punch, and the problem of leading to notch out-of-flatness aggravates.
Utility model content
The utility model aim is to provide a kind of half punching diel, it can be efficiently solved in the presence of background technology
The problem of.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of half punching diel, including rack, the upper rack is provided with punch and driving punch carries out punching press
Driving cylinder, the frame lower is provided with putting groove, stamped groove corresponding with punch is provided in the putting groove, described
Punch side is provided with guiding surface, and the Buffer Unit that can laterally stretch is provided in the stamped groove, and the Buffer Unit is set
It is equipped with parallel pressure-bearing inclined-plane corresponding with guiding surface.
Utility model works principle is as follows：
When use drive cylinder drive punch to push, punch falls into stamped groove and is punched out, guiding surface to wash open five
Golden plate material carries out guiding bending, and when punch pushes, Buffer Unit generates it supporting role, and guiding surface is clamped with pressure-bearing inclined-plane
The hardware plank washed open, it is ensured that the planarization of hardware plank；Using laterally flexible Buffer Unit, punch and buffering group are avoided
Pressure is excessive between part leads to hardware sheet deformation, ensures the precision of punching press.
Further, the Buffer Unit includes the sliding block that can laterally stretch, and the sliding block stretches into the connection of stamped groove one end
There are buffer stopper, the buffer stopper to be provided with pressure-bearing inclined-plane.
Guiding surface contradicts pressure-bearing inclined-plane when Buffer Unit is pressurized, and buffer stopper compression drives sliding block to contract along stamped groove side
Tightly, the impulse force that buffering punch pushes.
Further, the frame lower is provided with the holding tank for accommodating sliding block, is provided at the notch of the holding tank
Limited block is provided with anti-drop block on the sliding block, resetting spring corresponding with anti-drop block is provided in the holding tank.
Setting limited block plays restriction effect to sliding block, it is ensured that sliding block is slided along set direction；Simultaneously limited block with it is anti-
De- block cooperation, anti-limited slip block excessively skid off, it is ensured that guiding surface being capable of accurate fit with pressure-bearing inclined-plane when punch pushes；Anti-drop block
Screens effect is formed to resetting spring, it is ensured that resetting spring is stablized to sliding block into row buffering.
Further, the piercing edge of the ram bottom is respectively arranged with corresponding punching blade, the punching blade
Junction is provided with trepanning tip, matches with stamped groove on the outside of the trepanning tip.
It is set to the trepanning tip that stamped groove matches, it can be ensured that have height when the edge punching press of hardware plank
Planarization and precision；After carrying out trepanning by trepanning tip when punching press, cut by punching blade, it is ensured that the precision of notch.
Further, it is provided with the extension blade for extending to punching blade on the inside of the trepanning tip.
Extension blade, which is arranged, can ensure the planarization of notch in trepanning tip trepanning, convenient for cutting.
The utility model has the beneficial effects that：
The utility model setting Buffer Unit coordinates with punch, using laterally flexible Buffer Unit, avoids punch and delays
It rushes between component that pressure is excessive to lead to hardware sheet deformation, ensures the precision of punching press；Guiding surface has been rushed with the clamping of pressure-bearing inclined-plane
The hardware plank opened, it is ensured that the planarization of hardware plank.
