Description

A kind of LED lamp cover moulding process
Technical field
The present invention relates to a kind of mechanical processing technique, be specially a kind of LED lamp cover moulding process.
Background technology
So-called multi-station transfer die, generally refer to and to use on special multi-station punch, installed by process sequence by multiple stage die having certain technique to contact, passed a class mould of part by manipulator, each station is a complete stage die, completes specific technique, each stage die has certain contact, most important, each submodule Independent adjustable joint, and regulate general not by the restriction of front and back submodule.Multi-station transfer die is a kind of special type in diel.It both passed part with material strip unlike the progressive die, also unlike single station manual hand produce, can only complete one, two kind of simple process.From structure, each station is a pair independently single-station die, but from production process, can realize again automatically producing continuously as the progressive die, he combines the advantage of the progressive die and stage die.
At present, LED lamp cover is all completed by single tool and mould, because LED lamp cover is completed by multiple manufacturing procedure processing and fabricating, utilize single tool and mould to need many molds to be used in conjunction with each other, whole like this processing technology is complicated, add production cost, simultaneously because through the processing of too much mold, the technological requirement of workpiece will can not be ensured, easily occurs deviation in the fabrication process, precision is low, and production efficiency is low.
Therefore, for solving the problem, the present invention proposes a kind of new technical scheme.
Summary of the invention
The object of this invention is to provide that a kind of technique is simple, precision is high, reduce production cost simultaneously, improve the LED lamp cover moulding process of production effect.
The present invention is achieved through the following technical solutions:
A kind of LED lamp cover moulding process, described technique is completed by LED lamp cover transfer die, and described transfer die comprises stretching mould, seamless mould, perforating die, deburr or coin mould, secondary stretching mould, writing that surpasses all the others mould and reducing die, and described technique comprises following operation:
A, stretching: utilize stretching mould to carry out just being shaped to workpiece to be processed, described just shaping accounts for 2/3rds of whole shaped state;
B, seamless punching: the workpiece of pre-profiling is delivered to seamless mould, carry out seamless by seamless mould, and cambered surface seamless stretching gone out becomes T-shaped, and base angle seamless is become V-type, then passes to perforating die, and perforating die is to circular hole in the middle of T-shaped punching;
C, deburr or coin: deburr or coin process is carried out to workpiece by dabbing mould;
D, secondary stretching: carry out secondary stretching to workpiece, by stretching for 90 of workpiece both sides degree of right angles, complete the shaping of workpiece;
F, writing that surpasses all the others: carry out downward writing that surpasses all the others to workpiece by writing that surpasses all the others mould, make stretching both sides move down 2 ~ 5mm, and base angle V-type is struck out the final required angle of workpiece and shape;
G, reducing: carried out the reducing to workpiece by the different reducing die of three covers, first reducing die I is passed through by workpiece reducing to 15 ~ 18 degree, then reducing die II is passed to, reducing die II is by workpiece reducing to 20 ~ 28 degree, finally pass to reducing die III, reducing die III completes final reducing angle 35 ~ 40 degree.
Further, the movement of transferring work piece is carried out in described mould between each submodule by manipulator.
Further, described transfer die also comprises upper bolster, die shoe, lower piece and bottom plate, and described bottom plate surface is provided with lower piece, and described lower piece of upper surface connects die shoe, and each submodule is located between upper bolster and die shoe.
Beneficial effect of the present invention: this process structure is simple, come by LED lamp cover continuous mould, easy for operation, improve production efficiency, reduce production cost, ensure that the precision of workpiece simultaneously, and anti-upper process is to the damage of outward appearance, and each submodule can regulate mutually, ensure technological requirement.
