Based on analyzing the characteristic of self-press micro-irrigation system and the advantage and disadvantage of fertigation equipment is using,a simple and useful fertilizing equipment for self-press irrigation system was presented.

,belt down hill using step type three-phase anchor wire support technology which is using GRT-M6 M-belt to increase force bearing area,using rock deformation automatic bearing pressure characteristics to realize three-phrase consolidation have achieved good results.

Improved properly such mechanisms as the location,stripping and scraps treatment,the common compound die was satisfied the need of the automatic stamping.

Analysis on the punching technique of the stator & rotor core in compressor, optimized the layout, improved the die structure and machining process of double-row automatic overlapping-riveting horniness alloy progressive die.

Starting from optimal layout,the horniness alloy progressive die design critical points by dual automatic overlapping-riveting for plastic seal motor stator and rotor as well as manufacture process optimization are stated in detail.
