Description
Technical field
This utility model relates to a kind of punch structure, particularly a kind of thin material kidney-shaped small hole punching punch.
Background technology
Traditional piercing punch has a disadvantage in that 1, punching time, the waste material cropped is easily from the kidney-shaped aperture of mould
Emerging in place, part can be caused pressure wound；2, punch is one-body molded, and punch is big compared with long, intensity difference, difficulty of processing.
Utility model content
The purpose of this utility model is, it is provided that a kind of thin material kidney-shaped small hole punching punch.This utility model has anti-risk
Waste material is effective, the feature that punch is shorter, intensity is high, difficulty of processing is little, is connected firmly additionally, also have punch, changes quickly
Feature.
The technical solution of the utility model: a kind of thin material kidney-shaped small hole punching punch, includes upper mold, is provided with pressure in upper mold
Material mold insert, be provided with floating punch fixed block in binder mold insert, floating punch fixed block be arranged over dowel steel, floating punch is solid
Being provided with punch cushion block in determining block, connecting in floating punch fixed block has punch, the lower section of floating punch fixed block both sides to set respectively
There is a compression spring；The lower section of described upper mold is provided with lower mold, and lower mold is provided with die mold insert, and die mold insert is provided with punch
Hole, the lower section in punch hole is provided with cavity, the side of die mold insert is provided with air blowing mold insert, and air blowing mold insert is provided with and connects with cavity
Gas hole.
Aforesaid thin material kidney-shaped small hole punching punch, described punch has 2, and be arranged in parallel, and punch is provided with groove, and 2
It is provided with punch peg in floating punch fixed block between individual punch.
The beneficial effects of the utility model: this utility model passes through to arrange cavity in die mold insert, and at die mold insert
Side air blowing mold insert is set, the waste material cropped under air blowing mold insert leads to compressed-air actuated effect is blown die, it is to avoid
Part is caused pressure wound after emerging at the kidney-shaped aperture of die mold insert by waste material；Meanwhile, this utility model uses composite forming die
Structure, punch is hung in floating punch fixed block by punch peg, and punch is shorter, and therefore, its intensity is higher, and difficulty of processing is relatively
Little；It addition, punch of the present utility model is hung in floating punch fixed block by punch peg, it is connected firmly, changes quickly.Combine
Upper described, it is effective that this utility model has anti-risk waste material, punch compared with short, intensity is high, difficulty of processing is little, punch is connected firmly,
Change quick beneficial effect.

Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings, but is not intended as this utility model
The foundation limited.
Embodiment of the present utility model: a kind of thin material kidney-shaped small hole punching punch, includes upper mold 2, is provided with pressure in upper mold 2
Material mold insert 14, is provided with floating punch fixed block 4 in binder mold insert 14, floating punch fixed block 4 be arranged over dowel steel 1, floating
It is provided with punch cushion block 5 in dynamic punch fixed block 4, in floating punch fixed block 4, is provided with punch 6, floating punch fixed block 4 both sides
It is respectively arranged below with a compression spring 7；The lower section of described upper mold 2 is provided with lower mold 3, and lower mold 3 is provided with die mold insert 15, die
Mold insert 15 is provided with punch hole 10, and the lower section in punch hole 10 is provided with cavity 11, and the side of die mold insert 15 is provided with air blowing mold insert 12,
Air blowing mold insert 12 is provided with the gas hole 13 connected with cavity 11.
Described punch 6 has 2, and be arranged in parallel, and punch 6 is provided with groove 9, and the floating punch between 2 punch 6 is fixed
Be provided with punch peg 8(punch peg 8 in block 4 for cylinder, bottom a diameter of 2 punch 6 upper grooves 9 between distance).
Operation principle of the present utility model: during use, is placed in strip in lower mold 3, and the place alignment needing perforate is convex
Nib 10, upper mold presses for 2 times, and binder mold insert 14 pushes down strip, and dowel steel 1 moves down promotion floating punch fixed block 4 and moves down, and floats convex
Mould fixed block 4 drives punch 6 to move down, and to part cutting punching, the waste material cropped drops in cavity 11, is then blown up gas edge
Part 12 blows out and moves in die mold insert 15, dowel steel 1 and upper mold 2, and floating punch fixed block 4 recovers under the effect of compression spring 7
In situ, this work step punching completes.When changing punch 6, take out punch peg 8, old punch 6 is taken in floating punch fixed block
Under, then new punch 6 is loaded in floating punch fixed block 4, be inserted into punch peg 8, make punch peg 8 be stuck in groove 9
Locate.
