Description
Technical field
Diel FIELD OF THE INVENTIONThe is the utility model is related to, more specifically to a kind of punching without burr mould.
Background technology
In currently available technology punching without burr mould generally by half section of punching and back pressure by the inside crimped of burr to side
On wall, so as to avoid product surface from burr occur, product is prevented with causing scratch during other Product Assemblies, but its burr is given birth to
Into in product side wall, being unable to reach all carrot-free requirement of product surface and side wall.
Utility model content
Technical problem to be solved in the utility model there is provided a kind of punching without burr mould, can make product surface
With the equal impulse- free robustness of side wall.
Technical problem to be solved in the utility model is achieved by the following technical programs：
In order to solve the above technical problems, the utility model provides a kind of punching without burr mould, including half section of stamping die
Tool, back pressure device, hole punched device；Half section of punching press punching pin and punching press locating dowel are set in half section of diel；The back pressure
Back pressure punching pin and back pressure locating dowel are set on device；Stamping products first pass through half section of diel and carried out after punching press described time
Pressure device carries out back pressure to it, and the hole punched device is punched out to stamping products again, and half section of punching press punching pin pressing direction is with returning
Press punching pin pressing direction opposite；The hole punched device punching direction is consistent with back pressure punching pin pressing direction.
The utility model has the advantages that：
1st, product surface and the equal impulse- free robustness of side wall can be made；
2nd, waste material is directly dropped downwards by mould, reduces production cost；
3rd, long burr can be cut off.

Embodiment
The utility model is described in detail with reference to embodiment, embodiment is only of the present utility model preferred real
Mode is applied, is not to restriction of the present utility model.
A kind of punching without burr mould, including half section of diel, back pressure device, hole punched device, burr remover；It is described
Half section of punching press punching pin and punching press locating dowel are set in half section of diel；Back pressure punching pin and back pressure is set to determine in the back pressure device
Position post；Stamping products 1 first pass through the back pressure device after half section of diel carries out punching press and back pressure, the punching are carried out to it
Aperture apparatus is punched out to stamping products 1 again, and half section of punching press punching pin pressing direction is opposite with back pressure punching pin pressing direction；The punching
Aperture apparatus punching direction is consistent with back pressure punching pin pressing direction, its burr 3 is formed in the side wall of product 1, if blanking direction and
Back pressure is in opposite direction, and burr 3 still can be formed on the surface of product 1；The burr remover includes drift 4 and arc sections 5.
Refer to Fig. 1 to Fig. 4, half section of punching press punching pin is in part of the lower die, and half section of punching press punching pin is to upper semisection punching press；Described time
Punching pin is pressed in part of the upper die, the downward back pressure of back pressure punching pin；Burr 3 is formed in the side wall of product 1, does not interfere with the surface of product 1, described
The downward punching of hole punched device, burr 3 will not contact with waste material 2 during punching, and burr 3 is also not formed in production in the side wall of product 1
On the surface of product 1, there is no the risk of scratch, while downward punching when being assembled with other products 1, waste material 2 directly by mould to
Under drop, the downward punching press of burr remover, arc sections 5 are contacted with burr 3, and burr 3 is not only pushed power while is accompanied by
It is horizontal outwardly against power, burr 3 is flattened by arc sections 5, so as to reach the effect of flash removed 3, passes through above-mentioned steps
The surface impulse- free robustness of product 1 can be not only realized, the burr 3 of the side wall of product 1 can also also be removed, substantially increase product 1
Assembly precision, lift the mass of product 1.If back pressure direction and punching direction are upward, waste material 2 discharges difficulty, it is necessary to set up Ru Ding
The devices such as pin, blow pin, production is caused to rise originally too high, so back pressure direction and punching direction are most economical rational downwards.
Further, referring to Fig. 5, burr remover also includes cutting portion 6, when burr 3 is long, cutting portion 6 can be right
Long burr 3 is cut off, then is flattened by arc sections 5, and the burr 3 for making to be attached to the side wall of product 1 is reduced as far as possible.
Further, the punching without burr mould is the progressive die.
Above example only expresses embodiment of the present utility model, and its description is more specific and detailed, but can not
Therefore the limitation to the utility model patent scope is interpreted as, as long as being obtained using the form of equivalent substitution or equivalent transformation
Technical scheme, all should fall within the scope of protection of the utility model.
