Description

A kind of essence is rushed composite die
Technical field
The present invention relates to mould manufacturing field, relate in particular to a kind of essence and rush composite die.
Background technology
Essence punching belongs to the chipless machining technology, is a kind of fine blanking method that grows up on common stamping technology basis.The achievement of this processing method is to rush die-cut of part there is no crackle and tear on its whole material is thick.In addition, can also reach the tightest dimensional accuracy and glacing flatness tolerance.
Realize that fine-edge blanking must satisfy four conditions: 1, lathe condition 2, mould condition 3, material condition 4, lubricating condition.The lathe condition that wherein satisfies the essence punching must have the smart impact machine of three active forces.
The essence technology of rushing is an advanced manufacturing technology, and once essence punching just can obtain dimensional tolerance IT7~8 grade, and the part of shear surface roughness Ra 0.8~0.4um is equivalent to the quality of grinding in machining.With modulus 3, the number of teeth 18, thickness is that the gear of 5 millimeters is example, uses machining production, and every takes approximately 6 minutes, uses fine blanking technology production, per minute production more than 10.Rush in process in essence simultaneously, due to the effect of flow harden, its essence is rushed case hardness even can reach HRC42, and under many circumstances, fine blanking part often can be directly used in assembling and need not following process.Essence punching is that to utilize the mould of special construction directly to go out cross section quality on plate good, the part that dimensional accuracy is high, be applicable to the production of the tabular part of high accuracy in enormous quantities, in industries such as clock and watch, camera, precision instrument, household electrical appliance, be used widely at present.Common fine blanking technology, adopt the powerful flanging fine blanking die of gear ring, break through in journey in essence, section is that at first the gear ring of lance tooth is pressed into blank, utilizes the mechanical stop effect of gear ring and the frictional force between blank material and die, stops the blank material along continuous straight runs to flow, make blank material be in three-dimensional compressive stress state, crackle does not realize that the stamping-out of blank material separates in the situation that stretching does not appear in material, thereby it is good to obtain cross section quality, the blanking part that dimensional accuracy is high.The powerful flanging fine blanking die of present gear ring, only the one side at mould arranges gear ring pressing plate prevention blank material bottom horizontal flow sheet, only utilize the frictional force of die and blank to stop the blank material bottom horizontal flow sheet at another side, because frictional force is limited, therefore blank material can't produce enough large three-dimensional compression in the Pressing Deformation district, so blanking part cross section quality and the dimensional accuracy made are limited.
In the prior art, produce the fine blanking die of 3 millimeters 65Mn pads, the following problem of ubiquity: the Mould Machining difficulty is large, and the process-cycle is long; It is low that essence is rushed stock utilization; Mould follow-up maintenance expense is high; The life-span of the fine blanking die such as die, pressing plate core part is lower.
Summary of the invention
In view of the foregoing, the object of the invention is to produce thick is the part fine blanking die of the 65Mn material of 3 millimeters, further improves the utilization rate that essence is rushed material, improves the mold use life-span, reduce the follow-up maintenance expense, and guarantee that the roughness Ra of part stamping-out face is controlled at 0.8 micron.
For achieving the above object, the present invention proposes following technical scheme:
a kind of essence of the 65Mn material pad for the production of 3 millimeters thick is rushed composite die, and this composite die comprises, transmission rod 1, punch-die 2, material returned bar 3, material returned press rods 4, upper padding plate 5, upper mounted plate 6, upper balancing pole 7, locked mode pin pad 8, locked mode pin 9, gear ring plate 10, bullet top nail 11, back-pressure plate 12, die 13, stopple 14, punch retainer 15, lower bolster 16, lower balancing pole 17, back-pressure bar 18, step pitch nail 19, punch 20, the side block pin wherein, transmission rod 1 is arranged on punch-die 2 right sides, material returned bar 3 is arranged on punch-die 2 left sides, material returned press rods 4 next-door neighbour is arranged on material returned bar 3 left sides, upper padding plate 5 connects and is arranged on upper mounted plate 6 tops, upper balancing pole 7 is arranged on the bottom of upper mounted plate 6, and are connected with the locked mode pin with locked mode pin pad 8 and are connected, gear ring plate 10 is arranged on the left side that bullet pushes up nail 11, back-pressure plate 12 pushes up nail 11 with bullet and is connected, punch retainer 15 is connected with lower bolster and is connected the left side be arranged on lower balancing pole 17, back-pressure bar 18 is arranged on the right side of lower balancing pole 17, and are connected with punch with step pitch nail 19 and are connected.
