The specific embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
Preferred embodiment one:
As shown in Figure 2, this preferred embodiment provides a kind of progressive die that uses flange cutter flange, be provided with the flange station on this progressive die, the flange station be provided with counterdie 10 and with the suitable patrix 20 of counterdie 10, be fixedly installed on the other flange cutter 50 of counterdie 10, and the spring that is arranged on counterdie 10 belows.
The flange station is divided into two sub-stations, and a flange cutter 50 is set on each sub-station.Machined surface 51 angles on first sub-station flange cutter 50 are 60 ° (with the preformation shape, being 60 ° of angles), and machined surface 51 angles on second sub-station flange cutter 50 are 0 ° (with the preformation shape, paralleling).
Correspondingly, first sub-station counterdie machined surface 11 angles are 60 °, and second sub-station counterdie machined surface 11 angle is 0 °.
Workflow:
Techniques such as drawing, cut before step 10. material loading, workpiece 30 are completed and bending in advance at right angles, then enter into the flange station.Workpiece 30 is placed on counterdie 10, and the turn-up portion of workpiece 30 (as shown in phantom in FIG.) is placed on the machined surface 51 of the edge of counterdie 10 and corresponding flange cutter 50.
20 liftings of step 30. patrix, workpiece 30 enters next station, carries out follow-up sheet metal component work flow.
Step 40. counterdie 10 resets under the promotion of spring, wait for next workpiece.
Use flange cutter 50 in this preferred embodiment and with the common turn-up portion for workpiece 30 of the suitable counterdie of flange knife-edge shape 10, locate, top-down the exerting pressure of patrix 20 makes turn-up portion reach the crooked place of setting.This continuous mold structure is reasonable, and is easy to use, and floor space is little, and the metal plate flanging place quality of using this progressive die processing to obtain is good.
Preferred embodiment two:
This preferred embodiment provides a kind of progressive die that uses flange cutter flange, and its basic structure is identical with preferred embodiment one.
Difference is: make the spring that is not limited to of counterdie lifting after patrix lifts, can realize that the resetting means of reset function all can.The number of the included sub-station of flanging process is not limited to two, according to concrete shape and the processing conditions of workpiece, determines.Correspondingly, in every individual sub-station, the machined surface angle of flange cutter used increases successively, finally to reach the flange angle requirement of setting.
The work flow of this preferred embodiment is also identical with preferred embodiment one substrate.Difference is, overturning process is decomposed into multistep or settles the ground flange at one go and all according to specific product, determine, and can use the turn-up portion of flange cutter and counterdie fixation workpiece, upper right mould 20 pressure flange to get final product.
Flanging process comprises n stage, in the turn-up portion of i stage workpiece 30, by bending angle, is θ
iWherein, i is more than or equal to 1 and less than or equal to the positive integer of n.θ
iFor the angle that bends each time, that is, and the position that starting point reaches for last bending, the position that terminal reaches for this bending.The angle of each bending can be the same or different.After completing n stage, turn-up portion is bent to final position.
