Stall self-locking mechanism for manufacturing resin pipe by centrifugal molding process

Abstract

The invention relates to the technical field of centrifugal forming, in particular to a stall self-locking mechanism for manufacturing a resin pipe by centrifugal molding process. An electromagnet is fixedly connected to the interior of an outer shell, a supporting rod is movably connected to the inner wall of the electromagnet, and a gear ring is meshed with the position, located in the electromagnet, of one end of a half gear. A gear is meshed with the interior of the gear ring, a hollow mold is fixedly connected to a rotating shaft of the gear, an iron block is fixedly connected to the position, located outside a fixing frame, of one end of a push rod, a limiting spring is movably arranged at the position, located in the fixing frame, of the outer surface of the push rod in a sleeving manner, and a limiting block is fixedly connected to the position, extending into the gear ring, of the other end of the push rod. Starting and locking of the device are controlled through electricity and the electromagnet, higher sensitivity is achieved, excessive components do not need to be additionally arranged for locking, manufacturing materials of the device are saved, the stall phenomenon of the device can be effectively prevented, and the device is easy to control.

Description

technical field [0001] The invention relates to the technical field of centrifugal forming, in particular to a stall self-locking mechanism used in the manufacture of resin pipe centrifugal forming process. Background technique [0002] In the production of composite products, the centrifugal molding process is mainly used to manufacture pipes (buried pipes). It is to add resin, glass fiber and filler into the rotating mold cavity in a certain proportion and method, and at the same time, under the condition of heating , Relying on the centrifugal force generated by high-speed rotation, the material is extruded densely and solidified into shape. The centrifugal method has the advantages of stable quality, less loss of raw materials, and its overall cost is lower than that of steel pipes. [0003] Due to the high-speed centrifugal movement, the locking mechanism in the existing device is likely to fail after a long period of locking friction, which will cause the centrifugal m...

AI Technical Summary

Problems solved by technology

[0003] Due to the high-speed centrifugal movement, the locking mechanism in the existing device is likely to fail after a long period of locking friction, which will cause the centrifugal movement of the material to stall, even after the power is turned off. The device will still run, making it difficult to control the device, and it will also affect the forming effect of the pipe. During the high-speed rotation of the device, a large amount of lubricating material will be consumed between the bearings. If the method of manually adding lubricating oil is used, there will be certain safety hazards. Therefore, those skilled in the art provide a stall self-locking mechanism used in the centrifugal molding process of resin pipes to solve the problems raised in the above-mentioned background technology
