Description

A kind of automobile spare tire storehouse part trimming and piercing die mould
Technical field
The present invention relates to a kind of mould, especially relate to a kind of automobile spare tire storehouse part trimming and piercing die mould.
Background technology
The trimming and piercing die mould can produce vibrations and very big noise in process of production under at present a lot of situations, shakes the life-span that use equipment and mould itself are shortened in conference greatly.Traditional lower mold core is solid modelling, and mold weight is increased, and makes troubles for dismounting and the maintenance of mould.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of automobile spare tire storehouse part trimming and piercing die mould for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of automobile spare tire storehouse part trimming and piercing die mould is characterized in that this mould is made up of part of the lower die and part of the upper die,
The part of the lower die comprises die shoe, punch insert, Lifting Device and balance cylinder, described die shoe is arranged on below, described punch insert is fixed on the upper surface of die shoe, and described Lifting Device is located between part of the lower die and the part of the upper die, and described balance cylinder is located at the both sides of die shoe;
The part of the upper die comprises patrix holding pad, patrix drift, punching concave die cutter, patrix cutter piece, patrix edge-trimming cutter piece and upper ejector pin, one side of described patrix holding pad arranges patrix edge-trimming cutter piece, the below of this patrix edge-trimming cutter piece arranges patrix cutter piece, described patrix drift is located at the middle part of patrix holding pad, described punching concave die cutter is located at the bottom of patrix drift, and described upper ejector pin is installed on the patrix holding pad.
Be inlaid with on the described punch insert and insert, the weight that has not only alleviated mould itself has been brought convenience to maintenance again.
Described balance cylinder is the nitrogen cylinder, be provided with 4, as the balance in the mold work process and cushioning effect, had this device just can reduce noise and the vibrations that produce in the mold work process to a great extent, prolonged the service life of mould self, reduced using equipment damage.
Described upper push rod structure has upgraded the expensive traditional mode that last eccentric swage uses spring or nitrogen spring, has saved the expense of the maintenance of spring or nitrogen spring and periodic replacement.
Compared with prior art, the present invention has the following advantages:
(1) long service life: used the nitrogen cylinder to reduce the infringement that vibrations and strong impulsive force cause mould as buffering.
(2) easy to maintenance: lower mold core is used insert structure, entire die need not be hung maintenance sites when maintenance, takies a large amount of places, and inserting of only need will needing repairing pulled down and can be keeped in repair;
(3) manufacturing is low with maintenance cost: lower mold core uses insert structure to save the material of inoperative part; Last eccentric swage uses the mould of spring, and spring life is short to be damaged easily, in case change the risk of will the handlebar die ontology damaging or hurting sb.'s feelings timely, this mould has used upper push rod structure to get rid of above shortcoming, reduced maintenance cost.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
A kind of automobile spare tire storehouse part trimming and piercing die mould is made up of part of the lower die and part of the upper die, the part of the lower die is made up of die shoe 1, punch insert 2, Lifting Device and balance nitrogen cylinder, die shoe 1 is arranged at the below of this mould, and punch insert 2 is fixed in the upper surface of die shoe 1; The part of the upper die is made up of patrix holding pad 3, patrix drift 4, punching concave die cutter 5, patrix cutter piece 6, patrix edge-trimming cutter piece 7 and upper ejector pin, patrix edge-trimming cutter piece 7 is arranged at the top, patrix cutter piece 6 is arranged at the lower right of patrix edge-trimming cutter piece 7 and is attached thereto, patrix holding pad 3 is arranged at the middle below of patrix edge-trimming cutter piece 7 and is attached thereto, patrix drift 4 is connected the below of patrix edge-trimming cutter piece 7, be arranged at the centre position, punching concave die cutter 5 be arranged at patrix drift 4 under, upper ejector pin connects patrix holding pad 3.
This automobile spare tire storehouse part trimming and piercing die mould has adopted 4 nitrogen cylinder assemblies as the balance in the mold work process and cushioning effect, there has been this device just can reduce noise and the vibrations that produce in the mold work process to a great extent, prolonged the service life of mould self, reduced using equipment damage.
What the punch insert of this automobile spare tire storehouse part trimming and piercing die mould used is the pattern of inserting, and this structure has not only alleviated the weight of mould itself and brought convenience to maintenance again.
Use upper push rod structure to upgrade the expensive traditional mode that last eccentric swage uses spring or nitrogen spring.
The motion principle of this automobile spare tire storehouse part trimming and piercing die mould is, when depressing with specified pressure, press have last eccentric swage that tablet is compressed, do the trimming and piercing die action simultaneously by edge iron and drift then, a punching press action is covered, and press rises bottom knockout device jack-up part and takes out.
