Abstract

The invention discloses a plant fibre wire coil with integral structure and a pressing method and a special mold thereof. The special mold comprises a female mold, an upper punch, a lower punch and a core rod connected with the lower punch movably as well as a power device; the female mold is provided with a female mold frame which is provided with a cavity hole communicated with a cavity of the female mold; the female cavity consists of two parts which can be opened and closed; the lower punch consists of a lower punch A and a lower punch B; a punch head of the lower punch A moves axially in the cavity hole of the female mold frame and a lower coil plate cavity of the female mold; a punch head of the lower punch B moves axially in a cavity hole of the lower punch A; and the core rod is connected with the lower punch B movably. The pressing method comprises the following steps of: using the upper punch to press an upper coil plate, next using the lower punch A to press the lower coil plate and then using the lower punch B to press a winding drum by matching with the core rod. The invention has the advantages of even compaction, little damage ratio, large bearing capacity of finished product, short manufacturing procedure and low cost.

Description

Technical field: [0001] The invention relates to a plant fiber pressed product, in particular to a steel wire disc pressed with plant fiber, a pressing method and special equipment thereof. Background technique: [0002] At present, the cable reels and steel wire reels pressed by plant fibers such as crop straws can be recycled and reused, and the recovery rate can reach 100%. At the same time, they have the advantages of low cost, low pollution, and no need for fumigation treatment. generally welcome. But for a long time, due to the special shape of the cable reel and the steel wire reel, coupled with the poor fluidity of the plant fiber raw material and the particularity of the large volume change during the molding process, it has been proved that it is not feasible to adopt the general conceptual molding process such as the one-way molding process. , in the production and preparation process, there is generally uneven axial compaction density of the reel, especially the...
