Description
Technical field
The utility model belongs to the perforating tool technical field for perforation, more particularly to a kind of rushing for punching apparatus
Pressure head.
Background technology
Punch process occupies an important position in the processing industry of national economy；Punching press is at room temperature, to utilize installation
Mould on forcing press applies pressure to material, it is separated or is plastically deformed, so as to obtain a kind of pressure of required part
Processing method.Using punch machining process, there are good precision height, efficiency high, quality, saving material, low cost and other advantages.Punching
It is one kind of punch process, when carrying out punching press to workpiece using existing punching die, the direct punching press of drift is on workpiece, in work
Through hole is gone out on the surface of part.
The staking punch of present perforating press is mostly flat head, when punching, staking punch mating mold, in big punching press
Under power, hole is got on material, but because staking punch is flat head, it is easy to make the bore deformation pressed out, and have and compare
More burrs.Publication No. CN203484490U Chinese utility model patent discloses a kind of staking punch of perforating press, punching press
The lower surface of head is provided with inner cavity, and the upper surface of the inner cavity is less than lower surface, the lower surface of the staking punch and described interior
The lower surface of cavity is in same level.The beneficial effect of the utility model is：The lower surface of staking punch sets inner cavity,
Reduce the area of staking punch lower surface, pressure of the staking punch lower surface to material can be increased, it is easier to hole is gone out on material,
Burr is also less, and because joint-cutting is smaller, the hole rushed out is not allowed yielding.
Following defect be present in the utility model：The waste material that punching is gone out matches with inner cavity, is easily stuck in inner cavity, influences
The punching press of lower side, so as to need worker to manually take out, so not only causes production efficiency to reduce, and is also easy to weigh wounded the hand of worker
Refer to, cause production accident.
Utility model content
The purpose of this utility model is providing a kind of staking punch for punching apparatus, waste material during solving staking punch punching
The problem of being easily stuck in inner cavity.
In order to achieve the above object, base case of the present utility model is：For the staking punch of punching apparatus, including punching press
Head body, the lower surface of the staking punch body is provided with inner cavity, plunger is slidably connected in inner cavity；The inner cavity it is upper

State the second pressure valve that flowing groove is provided with above through hole；Being provided with the annular groove can connect with the inwall after workpiece punching
Tactile sponge.
In the case of by external force, second pressure valve is not closed, inner cavity is stretched out in the part that plunger is provided with sponge, sponge
A part is also exposed in the external world；And the part that plunger is provided with second pressure valve is located in inner cavity, the inside shape of inner cavity
Into closed space.When plunger is fully located in inner cavity, the air pressure in inner cavity increases to preset value, and second pressure valve is beaten
Open.
The operation principle of this base case is：When being punched out using this staking punch to workpiece, staking punch body is downward
Motion, plunger fall on the surface of workpiece at first, and in the presence of workpiece, plunger is pushed to inner cavity, is finally completely disposed at indent
Intracavitary, the gas in inner cavity are compressed, and the air pressure in inner cavity is more than ambient pressure.Staking punch body continues to move downward punching
Workpiece is pressed, stamps out through hole on the surface of workpiece.During plunger concaves chamber internal motion, plunger is gradually to rubber bag
It is close, rubber bag is extruded, the pressure increase that rubber bag is subject to, first pressure valve is opened, and the paint outflow in rubber bag, passes through stream
Dynamic groove is flowed into plunger.When plunger is completely disposed in inner cavity, second pressure valve is opened, and paint flows successively through flowing groove, led to
Hole, annular groove, are finally attached on sponge.After the completion of punching, due to the stop without workpiece, the work of gas in inner cavity
Under, plunger is pushed out, final to recover to original position, in this process second pressure valve closing.After the completion of punching, drive
Dynamic staking punch body is up, and during up, sponge contacts with the inwall after workpiece punching, and the paint on sponge is coated onto this
On inwall.
The beneficial effect of this base case is：
1st, plunger is compressed in punch process, the air pressure increase in inner cavity, after the completion of punching, utilizes the gas in inner cavity
Pressure promotes plunger outward to stretch out, and plunger can discharge the waste material being stuck in inner cavity in this process, avoids waste material from being stuck in interior
In cavity；
2nd, during punching, sponge on plunger can be can also be on the inwall after workpiece punching after the completion of punching press
Varnish with lacquer, prevent the inwall from getting rusty.
Further, the upper surface of the plunger is provided with the groove of truncated cone-shaped, and groove connects with flowing groove；The groove diameter
Upper surface of the less one end away from plunger.Paint in rubber bag can fall in a groove when flowing out, and then flow into and flow along groove
In dynamic groove.The setting of groove has receiving effect to paint, avoids paint from attaching on the inwall of inner cavity；And groove is arranged to round
Platform shape, truncated cone-shaped have the function that water conservancy diversion, paint is more easily flowed to flowing groove.
Further, the lower surface of the plunger is provided with rubber blanket.Rubber blanket is flexible, when plunger contacts with workpiece, rubber
Rubber cushion has the function that to buffer and protected, and avoids workpiece from being damaged.
Further, spring is connected between the inner cavity and plunger, one end of spring is connected to the upper wall of inner cavity, separately
One end is connected to the upper surface of plunger.When plunger is not acted on by external force, spring in a state of nature, was not both elongated or not pressed
Contracting.When the inside cavity side of plunger is moved, spring is compressed, and when plunger is not stopped by workpiece, spring is acted on plunger application
Making every effort to promote makes plunger restore to the original state.The setting of spring is the plunger in order to avoid when the poor sealing between plunger and inner cavity
Can not be automatically reset the occurrence of.
Further, the top of the staking punch body is provided with the gas tube connected with inner cavity, and gas tube is provided with valve.
Valve is opened, can be by gas tube toward being filled with air in inner cavity or releasing air in inner cavity, by adjusting inner cavity
In air pressure so as to pilot plunger position, the location of plunger is met actual demand.
Further, the position that the plunger contacts with inner cavity is provided with sealing gasket.Sealing gasket is used to strengthen plunger and indent
Sealing between chamber.
