Rubbing grinding device with rotary scraping function

Abstract

The invention discloses a rubbing grinding device with a rotary scraping function, and relates to a pipe forming and molding device for a concrete structure pipe, in particular to an improvement of arubbing grinding device for a core-type rotary vibration extrusion forming pipe making machine. By means of the rubbing grinding device with the rotary scraping function, on the basis of the basic function of grinding is achieved, and granular materials are prevented from being scattered and leaked during a pipe making process, so that material reduction, quality reduction of a pipe and influenceon normal operation of the whole device are avoided. A fixing flange (8) is fixedly connected to the bottom surface of a grinding frame; and the lower portion of the fixing flange (8) is connected toa rotating support inner ring (110) through a plurality of step screws (9). By means of the rubbing grinding device with the rotary scraping function, the function of the core-type rotary vibration extrusion forming pipe making machine is optimized, the structure of the core-type rotary vibration extrusion forming pipe making machine is perfected, and the device has certain forward-looking characteristics, and is suitable for widespread promotion in the field of concrete pipe manufacturing.

Description

technical field [0001] The invention relates to a pipe-making and forming production device for concrete-structured pipes, in particular to the improvement of the rolling and rubbing device of a core-raising rotary vibration extrusion forming pipe-making machine. Background technique [0002] For the current production equipment of reinforced concrete structure drainage pipes in China, the inventor submitted an invention patent application to the State Intellectual Property Office on January 13, 2016 after years of research and development, application number: 2016100253127, name: a kind of rising core Rotary vibration extrusion forming pipe making machine; the application was announced and authorized on 2017-12-26. [0003] The basic structure of the rubbing and rolling mechanism of this patent application is as follows: Figure 10 As shown, its basic structure and working principle are described in detail in the application document, and a brief introduction in this case i...

Problems solved by technology

[0005] However, during the actual development process of this patented technology, we found the following problems: In terms of raw material delivery, we adopted quantitative and intermittent addition supply; in terms of rolling feed, we adopted constant pressure or constant Stroke control mode, so in actual operation, we found that: first, because the socket fixed disk 14 of the rolling device has a certain width, there will be a lot of granular materials scattered on it; When molding to the top socket position of the pipe fitting, due to the reduction in the volume of the cavity of the mold and the vibration during the processing, raw material leakage will occur

Even if the project still has the function of rubbing and rolling in the future, due to the reduction caused by material scattering and leakage, the pipe fittings 19 (such as Figure 11 As shown) the top edge (socket 191) has defects of loose material (at fixed stroke) or inconsistent product length (at constant pressure); in addition, if the scattered materials are not cleaned manually in time, when the mold is replaced, it will Scattered to the lower part, seriously affecting the normal operation of bottom rotating parts and lifting parts

[0006] At the same time, we found that if the function of automatically removing the top granular material is added, the structure of this patent in the prior art is difficult to realize, and major improvements are required
