Abstract
The utility model relates to a punching mould of the digital control pressing machine, in particular to an air blowing type of the digital control pressing machine, which comprises an upper mould core, a driven head of the pressing machine which is arranged above the upper mould core, a blow hole which vertically runs through the upper mould core is arranged in the centre of the upper mould core, passing through the air inlet which is arranged in the driven head of the pressing machine, the superior end of the blow hole is communicated with the compressed air and air-supply device. The utility model is capable of effectively prevent the rebound phenomenon of the waste materials in the process of punching operation.
Description
Technical field
The utility model relates to a kind of diel of digitally-controlled press machine, particularly a kind of digitally-controlled press machine air blowing type patrix.
Background technology
The diel of digitally-controlled press machine is when carrying out the punching operation; because the patrix movement velocity is very fast; when patrix after the punching moves on rapidly, can between patrix and blanking, form instantaneous negative pressure, regular meeting makes blanking with moving on the patrix and taken down out of die orifice (being the waste material rebound phenomena).If the waste material of taking down die orifice out of is fallen down one side of die orifice, can when ensuing punching is moved, the compressive strain of working plate backing strap be scrapped, if mould is half of towards doubling plate simultaneously, when unbalance loading is serious the serious consequence that cutting edge bursts can take place; If take out of down die orifice waste material half be stuck in the workpiece hole, when half is stuck in down in the nib, the feed mechanism friction feeding can take place that clamp pulls, plate clashes into major accidents such as clamp and guard shield.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of digitally-controlled press machine air blowing type patrix that can prevent that the waste material bounce-back from taking place is provided.
Digitally-controlled press machine air blowing type patrix of the present utility model includes a upper mold core, there is the forcing press attacking head upper mold core top, at the center of upper mold core a gas hole that vertically connects upper mold core is arranged, the gas hole upper end is connected with compressed air supply unit through the air inlet of opening on the forcing press attacking head.
Digitally-controlled press machine air blowing type patrix of the present utility model is blown downwards by the gas hole on the upper mold core by control device in blanking moment when carrying out the punching operation, makes waste material break away from patrix, falls downwards, has prevented the bounce-back of waste material effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, the top of the upper mold core 1 of this digitally-controlled press machine air blowing type patrix is a forcing press attacking head 2, the upper mold core below is a counterdie 5, a gas hole 3 is longitudinally arranged at the center of upper mold core, and the gas hole upper end is connected with compressed air supply unit (not expressing among the figure) through the air inlet of opening on the forcing press attacking head 4.When blanking, blow out air-flow downwards by gas hole 3, make waste material 6 break away from patrix, fall downwards, prevented the bounce-back of waste material effectively.
Claims (1)
1, a kind of digitally-controlled press machine air blowing type patrix, it includes a upper mold core (1), there is forcing press attacking head (2) the upper mold core top, it is characterized in that: a gas hole (3) that vertically connects upper mold core is arranged at the center of upper mold core (1), and the gas hole upper end is connected with compressed air supply unit through the air inlet of opening on the forcing press attacking head (4).
