Embodiment

[0023] In this embodiment, the automatic production process of the subway segment is taken as an example to further describe the present invention in detail and completely. However, the process method involved in the present invention is equally applicable to concrete products of other shapes, specifications and uses in the field.

[0024] Such as figure 1 and figure 2 As shown, the automated production process of subway segments includes the following procedures in turn:

[0025] Step 1. Binding of steel bars: in the steel bar processing area (1), tie the steel bar skeleton of the segment on the fixed model to form a steel bar cage;

Abstract

The invention discloses an automatic production process of concrete precast products. The flow of the production process includes the sixteen working procedures of rebar binding, framework die entering, thickness detection of protective layers, automatic detection of gravel moisture, vacuum adsorption treatment and the like. By the adoption of the production process, concrete stirring water consumption in different weathers can be effectively calculated and adjusted, and then the production process can be more accurate. Through vacuum adsorption treatment, excessive moisture can be absorbed, products can be denser, the strength and the anti-corrosion capacity of the products are increased, and steam curing time of the products is shortened. By the adoption of low-temperature steam curing at the temperature lower than 45 DEG C, the products are prevented from cracking after water curing. The products are machined and manufactured on a flow production line which is automatically controlled, the quantity of labor force and labor intensity are reduced, operation is easy and convenient to conduct, mistakes are not easily made, and production efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of concrete production, and in particular relates to a production process for processing and manufacturing concrete prefabricated products on an automatic control assembly line. Background technique [0002] At present, the production process of concrete prefabricated products in the prior art is: model processing - concrete pouring - curing - demoulding and other four processes as the basic model. Its notable feature is that the position of the mold is fixed, and labor, materials, and hoisting equipment are in a state of constant motion to adapt to the corresponding process operations of the fixed mold. Therefore, the traditional mode of workshop has a large area, requires a lot of labor, takes time to return the hoisting equipment, wastes steam for maintenance, and is inefficient. [0003] In order to overcome the above difficulties, in recent years, many manufacturers have made the transition of concrete...
