Abstract
The utility model relates to a die, in particular to a die structure, which structurally comprises a lower die seat, and a die bearing plate and a die plate sequentially disposed on the lower die seat. A shearing die insert is embedded into the die plate, the shearing die insert, the die bearing plate and a lower die seat internal scrap via are communicated with one another, a blowing oblique hole communicated with the scrap via is arranged on the shearing die insert, the blowing oblique hole is communicated with an external air source through mutually communicated air holes arranged on the die plate, the die bearing plate and the lower die seat, the diameter of the blowing oblique hole on the die insert is smaller than that of the air hole on the die plate, and inclination of the blowing oblique hole on the die insert is smaller than 45 degrees. The die structure can timely and smoothly discharge scraps generate in blanking process, completely avoids die breakage and die insert bursting caused by scrap blockage in the via, and guarantees product quality while prolonging service life of workpieces.
Description
Technical field
The utility model relates to a kind of mould, specifically is meant a kind of die structure.
Background technology
When adopting die stamping-out aperture,, under the adhesion of punching oil, very easily in the die plate insert die cavity, stop up, cause the situation of punch fracture or die plate insert spalling because the waste material that stamping-out produces rolls in dropping process continuously.Therefore in the industry, (as shown in Figure 1), common waste material via sidewall at die shoe 4 was provided with air blowing inclined hole 41, made the waste material via hole 40 interior negative pressure that produce of die shoe 4, was convenient to blinking scrap whereabouts in the waste material via hole of top.But because the air blowing inclined hole is arranged on the die shoe 4, waste material via hole place is far away apart from the top, thus concave template insert 1 and concave template backing plate 3 on the waste material via hole still often cause obstruction because negative pressure is not enough.
The utility model content
Technical problem to be solved in the utility model provides a kind of blinking scrap whereabouts, novel die structure of effectively avoiding waste material to stop up be convenient to.
For solving the problems of the technologies described above, the utility model is realized by the following technical solutions:
A kind of novel die structure, comprise die shoe, be set in turn in die backing plate, concave template on the die shoe, concave template is embedded with the shearing die plate insert, the waste material via hole is connected in shearing die plate insert, die backing plate, the die shoe, and described shearing die plate insert is provided with the air blowing inclined hole that communicates with the waste material via hole.
Concrete, described air blowing inclined hole is connected external air source by the pore that is interconnected that is arranged on concave template, die backing plate and the die shoe; Air blowing inclined hole diameter on the described die plate insert is less than the diameter of the pore on the concave template.
Preferably, the air blowing inclined hole oblique angle on the described die plate insert is less than 45 °.
Preferred, the waste material via diameter on the described die backing plate is greater than 6.0mm, and die shoe waste material via diameter is greater than 8.0mm.
Compared with prior art, the effective effect of the utility model is: be to establish the air blowing inclined hole on the die plate insert in the blinking scrap source of generation directly in the described die structure, and the angle and the aperture of science design air blowing inclined hole, make the waste material that produces in the stamping-out process in time, discharge smoothly, effectively even can avoid fully causing punch to rupture and the situation of die plate insert spalling because of waste material takes place to stop up in via hole, and can reduce because of the punch fracture causes portion's product leakage punching phenomenon, improve workpiece assurance simultaneously in service life portion product quality.
Description of drawings
Die cross-sectional view in accompanying drawing 1 prior art;
Accompanying drawing 2 is novel die cross-sectional view described in the utility model.
The specific embodiment
For the ease of it will be appreciated by those skilled in the art that the utility model is done further introduction below in conjunction with accompanying drawing.
As Fig. 2, described novel die structure comprises: die shoe 4, be set in turn in die backing plate 3, concave template 2 on the die shoe 4, concave template 2 is embedded with shears die plate insert 1, the waste material via holes are connected in shearing die plate insert 1, die backing plate 3, the die shoe 4, and described shearing die plate insert 1 is provided with the air blowing inclined hole 11 that communicates with the waste material via hole.
On concave template 2, increase by a pore 21 in addition, corresponding increase by one through hole (pore) 31 on concave template backing plate 3, this through hole one end is communicated with pore 21, the pore of the connection external air source on the other end and the die shoe 4 is communicated with, and makes the external air source air communication cross the inclined hole 11 that these two holes directly blow to die plate insert 1.
During enforcement, inclined hole 11 diameters on the die plate insert 1 are generally got about ∮ 1.5mm, the diameter that it is less than pore 21 on the concave template 2, and making more has dynamics when air-flow is blown into the die plate insert die cavity, increase the negative pressure in the die cavity as far as possible.
The angle A of air blowing inclined hole 11 needs less than 45 °, and air-flow is blown toward the waste material falling direction as far as possible.Waste material via diameter on this mould concave template backing plate 3 is greater than ∮ 6.0mm in addition, and the waste material via diameter in the die shoe 4 is greater than ∮ 8.0mm, so that waste material falls.
