Abstract
A progressive die set for the high-precision flexible and continuous die pressing is composed of a band material feeding mechanism, a cylindrical material clamping and feeding mechanism, blanking module and drawing module. It features that said blanking module and drawing module are individual relatively, and it is only needed to regulate the step of blanking module and the workpiece to be formed for the workpieces to be drawn in same type.
Description
Technical field
The present invention relates to the metal stamping manufacture field, relate in particular to the punch machining process and the processing mold that need multiple operation drawing and forming part.
Background technology
Figure 1 shows that the part drawing of a tubular end cap.This part is adding man-hour, need carry out blanking, pull and stretch, punching, shaping and trimming process step to workpiece, is typical multiple operation drawing part.For this type of machining parts mainly is to adopt three kinds of approach.First method is to adopt the single die drawing and forming; Second method is to use the continuous drawing progressive die to realize punching press under the situation of size and deep-drawing technique permission; The third method is to utilize to transmit mould realization punching press on multiple position press.
The Tool and Die Technology content of first method is low, and input cost is few, and number of molds is many, and production efficiency is low.Second method Tool and Die Technology content height, the input cost height, the production efficiency height, but there are not adaptability and flexibility.The third method input cost height, the production efficiency height.But forcing press there is specific (special) requirements, only on multiple position press, utilizes the transmission mould to realize, be easy to the processing of large-scale profiled member.
Summary of the invention
The technical problem that patent of the present invention will solve is the flexible manufacturing method that a kind of serialization, flexibility, precise treatment are provided for multiple operation drawing and forming spare.
In order to realize above-mentioned target, the invention provides continuous punch forming process of a kind of novel flexible and progressive die structure.
The stamping procedure of pull and stretch after process aspect adopts first blanking, its basic stamping procedure is: blanking-pull and stretch, the pitch of the step pith of blanking and drawing and forming and later process can be unequal, the band material needs to determine according to the size of product blank in the step distance in blanking stage, and adjust within the specific limits by the product seriation requirement, the step distance of part remains unchanged when the punching press of drawing and forming and other later process.This stamping procedure has realized that band material is sent to, blanking separates with the drawing and forming operation, realizes that from operation blanking connects with flexibility between the molding procedure;
Adopt novel drawing and forming progressive die at the mould structure design aspect.Two modules greatly independently are installed on same mould bases.First module is installed the stamping and blanking mould, finishes the stamping and blanking operation of band material according to the step distance of blank.When billet size changes, adjust the step distance of band material, and adopt corresponding modular structure; Second largest module is installed protruding, dies such as drawing and forming, realizes part drawing and forming and other operations etc.When accessory size changes, be not adjusted to the type step pitch, only change the size of shaping jig, change moulding protruding, that the die workpiece is finished part.
The characteristics that do not wait at two big module step distance adopt two independently feed mechanisms respectively, guarantee the realization of punching production process flexibilitiesization, product specification seriation from mould structure.
As from the foregoing, the present invention makes blanking and molding procedure become flexible the connection, thereby has realized a kind of flexible continuous drawing method owing to adopted two separate modular structures.Progressive die by this method design promptly has the high characteristics of continuous drawing shaping mould production efficiency, has configuration flexibility and adaptability again simultaneously, and operation improves the forming parts precision to the influence of formed product quality before and after avoiding.

The specific embodiment
The operation principle of flexible continuous drawing progressive die is described below in conjunction with a concrete pull and stretch barrier part and mould structure.
According to the version and the size of part, realize that the operation of part continuous drawing moulding is:
1. blanking----2. pull and stretch----3. bottom reverse drawing----4. shaping----6. deburring of 5. punching----.
So in conjunction with the actual size requirement of flexible die structure and part, actual presser's figure place 8 times.The blanking operation divides two procedures to finish.Increase a room between punching and the trimming process step.
In the stamping and blanking module, 2 is the stamping-out stripper, and 4 is the blanking punch fixed form, and 3,5 is blanking punch, and 15 are band material feeder, and 16 is side shield.Fixed form and corresponding lower cavity die are individually fixed in up and down on the die holder 1 and 13.Workpiece is clamped by the step distance feeding by pay-off 15, finishes band material stamping-out and blanking by 3 and 5 punch at first and second stations.The waste material of stamping-out is discharged by material-dropping hole, and blank to be formed is sent into shaping station by the pay-off lifting clamping of second module.
In forming module, 6,7,8 is respectively the die of drawing and forming and trimming, is fixed in upper bolster, and corresponding punch is fixed in die shoe.14 is the loading and unloading material device, and 9 is punching concave die, and 10 are moulding deburring die, and 18 is the room punch.11,12 are moulding discharging and pay-off, and 17 is the side direction clamping device, and 19 is the part after the processing and forming.Workpiece behind the blanking is by sending into the drawing and forming operation by clamping device 17 and feed mechanism 12 in the forming module, finishes for the first time pull and stretch, pull and stretch and shaping punch process for the second time by die 6,7,8 and corresponding punch.And then send into punching and trimming process step is finished follow-up punching and deburring by die 9,10 and corresponding punch by the part of step feeder after with pull and stretch.
In the time of product specification need being adjusted as fruit series products, then change the punch-die and the stripper of stamping-out fixed head, correspondence in the blanking module.Adjust then at forming module that drawing and forming is protruding, the die workpiece.Adjust by the part, realize one module multiple usages, the punching production flexibility.The band material feeding direction of this part is consistent with the step direction of forming part.
