Description
Technical field
The present invention relates to a kind of screw head punch, belong to automobile stamping equipment technical field.
Background technology
When running into the circular product that some sizes are larger, plate is thicker, in die manufacture, in order to reduce product punching
Blanking pressure during pressure, the most frequently used mode is rushed or wavy edge for ladder, punching press constantly two angles or the same luck of multiple angles
It is dynamic, exist and the security risk such as mold damage or lathe, or even there is personal safety hidden danger.
The content of the invention
It is an object of the invention to provide a kind of screw head punch, blanking pressure is significantly reduced in punching course, is reduced
Noise is punched, protection mould and lathe are without prejudice, it is to avoid personnel are damaged.
Screw head punch of the present invention, including screw head punch body, screw head punch body first end are provided with spiral flushing tangent plane, spiral shell
The tangent plane that spins is provided with punching high point and punching low spot, and circumferentially one section of distance in the shape of a spiral for punching high point and punching low spot
Set.
Spiral flushing tangent plane is the working face of screw head punch, and spiral flushing tangent plane processing curl, screw head punch is transported in punching press
Remain that one direction of single-point rotates incision during dynamic, substantially reduce blanking pressure, meanwhile, reduce punching noise.
It is further preferred that punching high point is connected with screw head punch body cross section in transition.It is one to keep spiral flushing tangent plane
Individual smooth working face.
It is further preferred that punching low spot is connected with screw head punch body cross section in transition.It is one to keep spiral flushing tangent plane
Individual smooth working face.
It is further preferred that punching low spot is circumferentially that transition is connected apart from short one section with punching high point.Keep spiral
Punching face is a smooth working face.
Spiral flushing tangent plane excircle is set to screw type, and cross section is set to seamlessly transit in shape, blanking process, spiral flushing tangent plane
Blanking pressure is small, and noise is small.
When running into the circular product that some sizes are larger, plate is thicker, in die manufacture, in order to reduce product punching
Blanking pressure during pressure, the most frequently used mode is rushed or wavy edge for ladder, punching press constantly two angles or the same luck of multiple angles
Dynamic, blanking pressure is very big, exist in punching course because blanking pressure is big and the problem of the security risk such as mold damage.It is of the present invention
Screw head punch, by setting in spiral flushing tangent plane, punching course, remain that one direction of single-point rotates incision, spiral flushing
Tangent plane is set to seamlessly transit shape spiral flushing tangent plane, and blanking pressure is small, because be that one direction of single-point rotates incision, and blanking pressure is small,
Punching noise is substantially reduced, and is also solved because the problem of blanking pressure easily causes injury to mould, lathe and personnel greatly.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention is realized in blanking process and remained by setting spiral flushing tangent plane, punching high point and punching low spot
One direction of single-point rotates punching, and blanking pressure is small, and punching noise is small, at the same solve because caused by blanking pressure is big to mould,
The problem of lathe and personnel easily cause injury.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of one embodiment of the invention,
Fig. 2 is the main structure diagram of one embodiment of the invention,
Fig. 3 is the left view structural representation of one embodiment of the invention,
Fig. 4 is the overlooking the structure diagram of one embodiment of the invention.
In figure：1st, screw head punch body 2, spiral flushing tangent plane 3, punching high point 4, punching low spot.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Embodiment one
As shown in Figure 1 to 4, screw head punch of the present invention, including screw head punch body 1, the first end of screw head punch body 1
Provided with spiral flushing tangent plane 2, spiral flushing tangent plane 2 is punched high point 3 and punching low spot 4 edge provided with punching high point 3 and punching low spot 4
One section of circumferential distance length is set in the shape of a spiral.
Embodiment two
As shown in Figure 1 to 4, punching high point 3 is connected with the cross section of screw head punch body 1 in transition.Keep spiral flushing tangent plane 2
It is a smooth working face.Remaining be the same as Example one.
Embodiment three
As shown in Figure 1 to 4, punching low spot 4 is connected with the cross section of screw head punch body 1 in transition.Keep spiral flushing tangent plane 2
It is a smooth working face.Remaining be the same as Example one.
Example IV
As shown in Figure 1 to 4, punching low spot 4 is circumferentially that transition is connected apart from short one section with punching high point 3.Keep
Spiral flushing tangent plane 2 is a smooth working face.Remaining be the same as Example one.
The excircle of spiral flushing tangent plane 2 is set to screw type, and cross section is set to seamlessly transit in shape, blanking process, spiral punching
The blanking pressure of face 2 is small, and noise is small.
When running into the circular product that some sizes are larger, plate is thicker, in die manufacture, in order to reduce product punching
Blanking pressure during pressure, the most frequently used mode is rushed or wavy edge for ladder, punching press constantly two angles or the same luck of multiple angles
Dynamic, blanking pressure is very big, exist in punching course because blanking pressure is big and the problem of the security risk such as mold damage.It is of the present invention
Screw head punch, by setting in spiral flushing tangent plane 2, punching course, remain punching high point 3, a single-point, a direction
Rotation incision, spiral flushing tangent plane 2 is set to seamlessly transit shape spiral flushing tangent plane, and blanking pressure is small, because being that one direction of single-point rotates
Incision, and blanking pressure is small, punching noise is substantially reduced, and is also solved because blanking pressure is easily made greatly to mould, lathe and personnel
Into the problem of injury.
The course of work or operation principle：
Spiral flushing tangent plane 2 is the working face of screw head punch, and spiral flushing tangent plane 2 processes curl, and screw head punch is in punching press
Remain that one direction of punching 3 single-point of high point rotates incision in motion process, substantially reduce blanking pressure, meanwhile, reduce
It is punched noise.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God is with principle, and any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
