Characteristics of progressive die;

1) high efficiency of stamping production.Progressive die can complete the process of blanking, flanging, bending, drawing, three-dimensional forming and assembly of complex parts, reducing the intermediate transfer and repeated positioning and other work, and the increase of the number of stations does not affect the production efficiency, can be blanked small precision parts.

2) safe and simple operation.There is no need for the operator to reach into the dangerous area of the die during progressive die stamping.For mass production, also use automatic feeding mechanism, mold equipped with safety inspection device.

3) long die life.Within the complex shape and appearance can be broken down into simple convex die and concave die shape, block of successive cutting, process can be scattered in a number of location, textile machinery parts where there is a focus in the process of area can also be set 臵 space, avoiding the problem of convex and concave mold wall thickness is too small, change the stress state of convex and concave, increase the intensity of mold.In addition, the discharge plate is also used as the punch guide plate in the progressive die, which is very beneficial to improve the die life.

4) high product quality.The progressive die completes all the forming process of the product in one set of die, which overcomes the operation invariance and accumulated error caused by multiple positioning when using the simple die.

5) low production cost.Due to the complex structure of the progressive die, the manufacturing cost is high and the material utilization rate is low. However, due to the high production efficiency of the progressive die, the small number of presses, the small number of operators and workshop area required, the storage and transportation of semi-finished products are reduced, so the comprehensive production cost of product parts is not high.

6) design and manufacturing is difficult and highly experience-dependent.The progressive die has complex structure, high technical content, great flexibility and difficulty in design.Design and manufacturing experience, inference and visual measurement workload, talent training time is long, large differences between individuals;The same product parts can have a variety of different design scheme, design flexibility;Long design and manufacturing cycle, high cost, suitable for mass production.Progressive die is also limited by the size of the product parts, the size of the product should not be too large.
