Embodiment Construction

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0023] Such as figure 1 As shown, an inner wall grinding mechanism of a pipe mold includes a base 1 , a head frame 2 , a trolley 3 , a grinding mechanism 4 , an axial drive device and at least one bracket 5 . Both the head frame 2 and the bracket 5 are installed on the top of the base 1 .

[0024] The head frame 2 is equipped with a chuck 21 near the side of the bracket 5, and the chuck 21 is fixedly connected to one end of the pipe mold 6 coaxially, and a rotary drive mechanism (not shown) is also installed on the head frame 2 The rotary drive mechanism is connected to one end of the chuck 21 and drives the chuck 21 to rotate, thereby driving the pipe mold 6 to rotate. Such as image 3 As shown, the bracket 5 in...

Abstract

The invention relates to a lining grinding mechanism for pipe die repairing. The lining grinding mechanism comprises a base, a headstock, a bracket, a grinding mechanism body and an axial driving device, wherein the headstock and the bracket are mounted at the top of the base; the bracket is used for supporting a pipe die, so that the axial direction of the pipe die is horizontal; the headstock drives the pipe die to rotate; the grinding mechanism is arranged in the pipe die, the grinding mechanism is further rotationally connected with at least two riding wheels through riding wheel frames, and the riding wheels are in rolling fit with the inner wall of the pipe die; and the axial driving device is connected with the grinding mechanism and the base and drives the grinding mechanism to slide in the axial direction of the pipe die. After a cement lining of the pipe die is coated, a grinding wheel is replaced with the grinding mechanism, so that the noise is low, and the required motor power is also reduced, and in addition, safety and stability are realized, and the defect that the grinding wheel is easy to break is overcome.

Description

technical field [0001] The invention relates to the technical field of pipe mold repair, in particular to a lining grinding mechanism for pipe mold repair. Background technique [0002] Centrifugal casting is a technology and method of injecting liquid metal into a high-speed rotating mold, making the molten metal centrifugally move to fill the mold and form a casting. Due to the centrifugal movement, the liquid metal can fill the mold well in the radial direction and form the free surface of the casting; a cylindrical inner hole can be obtained without a core; it is helpful for the removal of gas and inclusions in the liquid metal; it affects the metal Crystallization process, thereby improving the mechanical and physical properties of the casting. [0003] In centrifugal casting, it is necessary to use a pipe mold with good mechanical properties and light wall thickness. In order to improve the service life of the ductile iron pipe, the inner wall of the ductile iron pip...
