Demolding method and equipment for large-scale winding product

Abstract

The invention belongs to the technical field of demoulding of winding products, and particularly discloses a demolding method and equipment for a large-scale winding product. The method comprises the steps that a mold and the product can be radially separated through the shrinkage of the opening and closing type mold, and the mold is connected to a machine frame and a cantilever support; the product is supported by second movable trolleys and moves in the direction of the cantilever support so that one end of the mold can be exposed; when the mold is exposed above a half length, the movement of the second movable trolleys is stopped, a first movable trolley is enabled to move to the middle position of the mold and support the mold; the mold is separated from the cantilever support, the cantilever support is enabled to move outwards, then the second movable trolleys are enabled to move so as to drive the product to be continuously demolded until the product is completely separated from the mold, and therefore the whole demolding procesdure is completed; and the equipment is used for implementing the method. The device and the method can effectively solve the de-molding problem in the winding production process of the large-scale oversized and overlong winding products and has the advantages of being convenient and rapid to demold, simple in equipment structure, convenient to operate and the like.

Description

technical field [0001] The invention belongs to the technical field of demoulding of winding products, and more particularly relates to a method and equipment for demolding large-scale winding products. Background technique [0002] Winding products are products made of continuous fibers such as glass fiber, carbon fiber, aramid fiber, bamboo fiber, wood fiber, bamboo-wood composite fiber, etc., using winding technology, such as winding composite pipes, winding storage tanks, winding poles, winding Pipe gallery, etc. Bamboo winding composite material is an emerging bio-based material, which is made of bamboo strips adhered with resin. [0003] With the continuous development of bamboo winding technology, it has also been applied in the field of railway transportation, such as using bamboo materials and using winding technology to directly form large-scale product carriages. It has the advantages of high tensile strength, strong buffer capacity, good thermal insulation and f...

Problems solved by technology

[0004] However, further studies have shown that since the winding carriage is a large-scale winding product with a length of tens of meters, compared with the previous small winding products, it has the characteristics of long overall size and heavy weight of the finished product, so the above-mentioned existing demoulding process is adopted. There are the following problems when demolding: using a release agent to demould requires a certain taper in the mold, but it is difficult to form a taper for a mold used to form a finished product with a length of tens of meters, and the demoulding resistance is large, especially for large products with a length of Products up to tens of meters are difficult to demould; the cantilever spindle is used to cooperate with the opening and closing mold to realize demoulding. Firstly, it is difficult to support molds and products that are too long and heavy. Secondly, it is only suitable for winding products with small lengths. Demoulding, but it is impossible to achieve the demoulding of large products, especially products with a length of tens of meters
