Problems solved by technology
Since only one forming mold can be carried on the forming tray, that is, only one concrete precast component can be formed at a time, so there is a problem of low production efficiency, which cannot meet the needs of mass production of concrete precast components
In addition, since the transmission belt pulley is fixedly installed on the molding die body, the transmission belt needs to be removed every time the molding die is replaced, and the operation is cumbersome, which does not reduce the labor intensity of workers and increases the production cost of the molding die

Embodiment Construction
[0019] The roller unit 30 is provided with a positioning device and a locking device for fixing the forming mold. In order to prevent axial movement during the rotation of the roller unit 30, there is an axial limit between the roller unit 20 and the roller unit 30. bit structure. The rolling unit 20 and the roller unit 30 can adopt many different structures, and the specific structure of the axial limit structure needs to be adapted to it.
[0020] image 3 and Figure 4 It shows a structure of the roller unit 30 with the simplest structure, that is, the roller unit 30 is a roller cage composed of roller rings 31 arranged at intervals in the axial direction and horizontal tubes 32 arranged along the circumferential direction of the roller rings 31. 32 is fixedly connected with each rolling ring 31 to form an integral body. refer to figure 2 and Figure 5 , the axial limit is formed by the retaining ring 21 formed radially outward on the outer peripheral surface of the t...

The invention discloses a centrifugal molding machine for a precast concrete member and aims to provide a centrifugal molding machine which can drastically improve the efficiency of precast concrete member production and can be operated conveniently. The centrifugal molding machine comprises: rolling units (20) which are arranged on a machine frame (10) at equal intervals in a row along the length direction; roller units (30) which are provided with moulds inside and are arranged between adjacent rolling units (20) to form friction transmission with the rolling units (20); and a power system which can drive any rolling unit (20) to rotate. The invention has the advantages of: drastically improving the efficiency of precast concrete member production and meeting needs for mass production on the premise of ensuring the compactness of the inside of the precast concrete member and the finish of the outside of the precast concrete member; having a simple structure and simple and convenientoperation and reducing the work intensity of workers; and forming a flexible production line of precast concrete member due to flexible arrangement according to production scale and spot condition.
Description
technical field [0001] The invention relates to a concrete prefabricated component forming machine, in particular to a centrifugal forming machine for producing concrete prefabricated components. Background technique [0002] A large number of prefabricated concrete components are used in the guardrails of highways, railways and municipal projects, such as railings, railing pillars, etc. In the past, most of these prefabricated concrete components were produced by traditional hand-made methods, which had the disadvantages of high labor intensity and low production efficiency, and the produced concrete prefabricated components had rough surfaces, many honeycomb pits, and poor compactness, which affected The appearance and inner quality of the product. For this reason, people have invented centrifugal forming device. [0003] For example, in the utility model patent specification whose patent number is ZL200620122709.X and authorized announcement number is CN2928444Y, a kind...
