Description
Technical Field
The invention relates to the technical field of prefabricated part production, in particular to a prefabricated part forming machine.
Background
The prefabricated member refers to a steel, wood or concrete member previously manufactured in a factory or on the site according to design specifications. The concrete prefabricated part is a building part which is manufactured in a factory in advance by taking concrete as a basic material, and the concrete prefabricated part not only plays an advantage in the aspects of function and safety, but also plays an advantage in the aspects of economy, creation of comfortable environment and resource saving; the prefabricated building components comprise walls, beams, plates, columns, pipe fittings, well covers and the like; however, the existing prefabricated part molding machine has the following problems:
1. in the process of forming the prefabricated part, the conventional prefabricated part forming machine generally pours raw materials into a mold manually or by a concrete truck, and then disperses and uniformly disperses the concrete raw materials in the mold manually to form the prefabricated part, so that the material distribution is uneven, time and labor are wasted, the quality of the prepared prefabricated part is uneven, and the production efficiency is low;
2. in the demolding process of the prefabricated part, the mold is required to be turned over to the state that the opening of the cavity faces downwards, then the side wall of the mold is repeatedly knocked to enable the prefabricated part to be separated from the mold, or the side plates of the mold are detached one by one to complete demolding, so that the demolding process is complicated, time-consuming and labor-consuming.
3. When the mold is provided with two stations in the processes of forming the prefabricated part and demolding, the first station is that the cavity opening of the mold faces upwards and receives the raw material to form the prefabricated part, and the second station is that the cavity opening of the mold faces downwards and demolds the prefabricated part from the mold; however, when the mold is switched between the first station and the second station, the mold is generally turned over by manpower, which wastes time and labor and is low in efficiency; or other overturning mechanical equipment is utilized to overturn the die, wherein the overturning mechanical equipment needs to be aligned and matched with the die to accurately overturn the die every time the die is overturned, and the overturning efficiency is low.
4. When the mold receives the concrete raw material, the mold is required to be moved to the demolding position of the prefabricated part, and generally, the mold moves up and down to a position close to the ground for demolding; however, when the concrete material is not completely solidified and fixed for molding, the upward and downward movement of the mold may cause the mold to tilt, and the surface of the prefabricated part may tilt, which may affect the molding quality of the prefabricated part.
5. In order to enhance the structural strength of the concrete prefabricated part, a steel bar structure is generally arranged in a mold before the concrete prefabricated part is formed, and then concrete is poured to form the concrete prefabricated part with the steel bar structure; however, after the steel bar structure is placed in the mold, the steel bar structure cannot be fixed, and can be impacted and displaced by the impact force of concrete during concrete pouring and cannot be fixed in the middle of the mold, and the steel bar structure cannot be located in the middle of the concrete prefabricated part, so that the overall structural strength of the concrete prefabricated part is unbalanced, and the structural strength is weakened; and steel bar structure can sink in the mould bottom so that steel bar structure can expose at the precast concrete component bottom surface, and exposed reinforcing bar influences the planarization of precast concrete component bottom surface, influences later stage assembly and uses.
In view of the above, the present inventors have made extensive studies and studies to develop and design the present invention in view of the drawbacks and inconveniences caused by the imperfect structural design of the above-mentioned forming machine for prefabricated parts.
