Description
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 use on special multi-station punch, installed by process sequence by multiple stage dies having certain technique to contact, passed a class mould of part by mechanical hand, each station is a complete stage die, completes specific technique, each stage die has certain contact, most important, each submodule Independent adjustable saves, and regulates 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 hands produce, can be only done one, two kind of simple process.From structure, each station is a secondary independent single-station die, but from production process, can realize again automatically producing continuously, the advantage that he combines the progressive die and stage die as the progressive die.
At present, LED lamp cover is all completed by either simplex mould, because LED lamp cover is completed by multiple manufacturing procedure processing and fabricatings, utilizing either simplex mould to need many molds to be used in conjunction with each other, so whole processing technique is complicated, add production cost, simultaneously as will through the processing of too much mold, it is impossible to ensure the technological requirement of workpiece, deviation easily occurs in the fabrication process, precision is low, and production efficiency is low.
Therefore, for solving the problems referred to above, the present invention proposes a kind of new technical scheme.
Summary of the invention
Technique is simple, precision is high to it is an object of the invention to provide one, reduces production cost simultaneously, improves 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 includes stretching mould, seamless mould, perforating die, dabbing limit mould, secondary stretching mould, writing that surpasses all the others mould and reducing die, and described technique includes following operation:
A, stretching: utilizing stretching mould that workpiece to be processed carries out just shaping, described just shaping accounts for 2/3rds of whole shaped state;
B, seamless punching: the workpiece just shaped 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, is then passed to perforating die, and perforating die is to circular hole in the middle of T-shaped punching；
C, dabbing limit: workpiece is carried out the process of dabbing limit by dabbing limit mould；
The 90 of workpiece both sides degree of right angles are stretched, complete the shaping of workpiece by d, secondary stretching: workpiece is carried out secondary stretching；
F, writing that surpasses all the others: workpiece is carried out downward writing that surpasses all the others by writing that surpasses all the others mould, make the both sides stretched move down 2 ~ 5mm, and base angle V-type strike out the finally required angle of workpiece and shape；
G, reducing: overlap different reducing dies by three and complete the reducing to workpiece, first pass through reducing die I by workpiece reducing to 15 ~ 18 degree, it is then passed to reducing die II, reducing die II is by workpiece reducing to 20 ~ 28 degree, being ultimately transferred 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 mechanical hand.
Further, described transfer die also includes upper bolster, die shoe, lower piece and bottom plate, and described bottom plate upper 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 effects of the present invention: this process structure is simple, completed by LED lamp cover continuous mould, easy for operation, improve production efficiency, reduce production cost, ensure that the precision of workpiece and the anti-upper course of processing damage to outward appearance simultaneously, and each submodule can regulate mutually, it is ensured that technological requirement.
