Description
Technical field
The invention belongs to a kind of mould, particularly relating to a kind of high speed and precision stamping die duplex sequence combined die structure for making automobile terminal.
Background technology
Automative wiring terminal now automobile industry is generally applied to give and is facilitated the connection of wire to apply, terminal is connected with wire and adopts special crimping apparatus the two to be crimped together, different electrical appliances need adopt different square wire diameter conductor compression jointings square because electrical current is different, certain compression joint area is to ensure reliable contacts, and guarantees by enough electric currents.Terminal is high by efficiency, and precision is good, and high speed stamping continuous mould easy to maintenance realizes.
Terminal is made up of conductor bag cylinder, insulating bag cylinder and functional areas three part, for the crimping of coupling different conductor wire diameter, the conductor bag cylinder of terminal, insulating bag cylinder design different model, i.e. the model terminal (height and the width dimensions of bag cylinder vary in size) such as A type, Type B, C type, D type.As A code name represents that this terminal can crimp the electric wire of 0.5-0.75 square millimeter, be convenient to the model of user's energy recognition terminal when crimping lead wire.Code name difference represents that wire diameter is different.
Insulating bag cylinder and the chamfering on conductor bag cylinder realize wire and become a significant design overall reliably after terminal compression joint.The insulating bag cylinder back side " A ", " B ", " C ", " D " and etc. code name be facilitate recognition terminal model or prevent user from using terminal and the unmatched mistake of wire.
Terminal stamping continuous die (also known as progressive die), with certain speed (300-1000 beat/min), in a punching stroke, cold rolling copper alloy billot enter a secondary mould carries out punching, cold stamping punch die that pressure word, blanking, the different station such as bending, shaping complete multi-step forming processes simultaneously, mould upper and lower mould often closes and opens a punching press and completes once, material strip fixed-distance moving once, completes to this terminal is shaping.Pressure word operation adopts pressure word punch and die to form the stamping procedure of the different conductor wire diameter crimping model such as corporate logo and crimping A, B, C, D on billot surface.Flanging operation is that pressured limit punch and die will be pressed into the chamfering with certain angle in crimping lead wire position after terminal blanking, uses in order to special crimping apparatus.
At present, generally adopt to press down word crimping technique: it is as shaping in models such as A, B, C, D that pressure word punch and flanging punch carry out product, as shaping category-A terminal, die mounting strap " A " word die, then change the die of coupling, mounting strap " B " word die, shaping C class terminal, then change the die of coupling, mounting strap " C " word die etc. changes successively; The conductor bag cylinder of the corresponding different size of terminal of different model and insulating bag cylinder, when the conductor bag cylinder of punch forming category-A terminal and the flanging of insulating bag cylinder, change and install the flanging die of A model, when the conductor bag cylinder of punch forming category-B terminal and the flanging of insulating bag cylinder, change and install the flanging die of Type B number, change other model according to above-mentioned replacing.
Change when producing terminal kind the pressure word die mold insert of same model must be changed with the flanging die mold insert mated simultaneously, otherwise will occur terminal batch manufacturing scrap or cause terminal model and wire diameter not to mate crimping mistake, the security reliability of wire harness lowers greatly.
Summary of the invention
Technical problem to be solved by this invention is cannot be shaping the complete shaping two step operations of namely dividing of operation for pressure word and flanging, cause change kind convenience and mould maintenanceability poor, a kind of terminal high speed and precision stamping die duplexing sequence combined die structure is provided.
In order to solve the problems of the technologies described above by the following technical solutions: a kind of terminal high speed and precision stamping die duplex sequence combined die structure, arranges pressure word and flanging operation that one group of die mold insert completes different model terminal in same die nibs.
The pressure word die mold insert of stamping forming different model terminal and the flanging die mold insert of stamping forming different model terminal are designed to one group of duplex sequence combined die mold insert, make different station die mold insert be arranged in the different die nibs of die.
The four sides of described die is equipped with die nibs, arranges one group of duplex sequence combined die mold insert in each die nibs, and four groups of duplex sequence combined die mold inserts all can punch forming.
Structure of the present invention is simple, single easy to operate, multidirectional punch forming simultaneously, make separate pressure word and flanging die mold insert become one, and the requirement of terminal difference crimping model can be met by this body of upset, reach save time, saving of labor, material-saving and error-disable function object.

Detailed description of the invention
As shown in Figure 1, 2, a kind of terminal high speed and precision stamping die duplex sequence combined die structure, arranges pressure word and flanging operation that one group of die mold insert completes different model terminal in same die nibs.Comprise die 1 body, the pressure word die mold insert 2 of the different model terminal such as punch forming " A ", " B ", " C ", " D " and the flanging die mold insert 3 of the different model terminal such as punch forming " A ", " B ", " C ", " D " are designed to one group of duplex sequence combined die mold insert, make different station die mold insert be combined in the die nibs of same station, greatly facilitate terminal model to change product, and have error-disable function.
As shown in Figure 2, the course of work is as follows: punch die patrix is descending, and cold rolling copper strips billot is sent to by automatic feeding set a distance, passes through from stock guide, enters each operation in concave template.
First operation: drum pressure bag punch is descending with the bulge on the shaping billot of die.
Second operation: piercing punch carries out punching press correcting pin-and-hole, does billot and sends location use to.
3rd operation: piercing punch carries out punching.
4th operation: pilot pin correcting station.
5th operation: the die-cut expansion profile of blanking punch.
6th operation: pilot pin correcting station.
7th operation: punch of finding fault carries out product and finds fault shaping.
8th operation: the pressure word of forming terminal and flanging; Flanging operation adopts the chamfering hypotenuse on flanging punch and die shaping conductor bag cylinder, insulating bag cylinder; Pressure word operation adopts pressure word punch and die to form the code names such as A, B, C, D on the surface of terminal insulative bag cylinder.
9th operation: the bending shaping U-shaped of punch.
Tenth operation: forming convax mould carries out preformed.
11 operation: forming convax mould carries out shaping.
12 operation: it is shaping that forming convax mould carries out rectification.
Complete above-mentioned work station product punching press successively and complete shaping sending.
Different terminal die is the same similar, and just stock layout is different with operation quantity.
