Abstract
The invention discloses a movable stamping die comprising a stamping shell. The stamping shell is internally provided with a movable stamping device. The movable stamping device comprises a stamping rod base, a stamping rod, a stamping die and a spring, wherein the stamping die is internally provided with a cavity which is matched with the stamping rod for use; one end of the stamping rod is connected with the bottom of the stamping rod base, and the other end of the stamping rod is inserted in the cavity; the spring is connected between the stamping rod base and the stamping die; and a through hole is arranged on the side wall of the stamping shell. According to the scheme of the movable stamping die, with the adoption of the structural design of the combined type movable stamping device, the movable stamping die is convenient to install and dismantle, and the deformation can achieve 5-6 times; products with large cold heading and large deformation can be produced by the movable stamping die; and through the through hole arranged on the side wall of the stamping shell, the problem related to the emission of hot gas can be effectively solved, and the pass percent of the stamping is improved.
Description
Technical field
The present invention relates to a kind of mould, relate in particular to a kind of movable punch die.
Background technology
Present widely used punch die is fixed punch die structure; Soon drift in the shaped device and contoured squeeze board are fixed and maintain static after plate is fastened on the template by screw; Inconvenience is not only installed, dismantled to the punch die of this structure, and can only satisfy in the cold heading technique scientific principle opinion regulation steady-state deformation cold forging than the product less than 3 times; When the punching press head especially big; And during the short weld bolt of bar portion; Its upsetting ratio is up to 6 times; Use this fixed punch die structure to make its leading edge deformation difficulty; Be difficult to continuous production; Big and the shorter deformation of bar minister degree of this product head in addition moves at each station when being unfavorable for the product cold upset forming and causes producing continuously difficulty.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed the big movable punch die of a kind of installation, convenient disassembly and shaping and deformation amount.
Technical solution of the present invention is achieved in that a kind of movable punch die, comprises towards shell, saidly in shell, is provided with movable decompressor; Said movable decompressor comprises towards the rod seat, dashes rod, punch die and spring; Be provided with in the said punch die and the shape chamber that is used towards rod; Said being connected towards an excellent end dashed excellent bottom, and the other end inserts in the die cavity; Said spring is connected and dashes between rod seat and the punch die.
Preferably, saidly be provided with through hole towards shell side wall.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
A kind of movable punch die of the present invention through the structural design of combined movable decompressor, makes its installation, convenient disassembly, and its deflection can reach 5～6 times, and it is bigger to produce qualified cold-heading through this punch die, the product that deflection is big; Through on shell side wall, being provided with through hole, can effectively solve the discharging of hot gas, improve the punching press qualification rate.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is not status architecture sketch map during punching press of a kind of movable punch die of the present invention;
Accompanying drawing 2 is a status architecture sketch map after a kind of movable punch die punching press of the present invention
Wherein: 1, towards shell; 2, dash the rod seat; 3, dash rod; 4, punch die; 5, spring; 6, shape chamber; 7, through hole; 8, Nei Ren.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
