Problems solved by technology

However, the iron filings removed during the removal of scale by these two methods are likely to adhere to the inner wall of the pipe due to the high temperature, resulting in low removal efficiency of the actual scale, and the surface quality of the processed pipe is not high.

Embodiment 1

[0040] see Figure 1-9 As shown, the centrifugal equipment used for the inner surface treatment of pipes includes:

[0041] The base body 10 has a through hole for placing the pipe material 60 on the base body 10,

[0042] The manipulator 20 is installed on the substrate 10, and the manipulator 20 is used to clamp the grinding assembly 30 and drive the grinding assembly 30 to rotate to grind the inner wall of the pipe 60,

[0043] Wherein, the gap between the pipe material 60 and the through hole on the base body 10 is filled with the fastener 40, the fastener 40 includes a first ring body 41 sleeved on the outer wall of the pipe material 60, the first ring body 41 is connected with a coaxial second The ring body 42, the diameter of the upper and lower ends of the second ring body 42 is not equal, the smaller diameter end is connected with the first ring body 40 and is equal in diameter, the second ring body 42 is separated by a notch 43 into several sections, and the first r...

Embodiment 2

[0060]The substrate 10 in the centrifugal equipment used for the inner surface treatment of pipes in the present invention can be a frame or other substrates for supporting and assembling parts, and should not be limited to its structural shape. The diameter of the through hole on the substrate 10 is larger than the processed pipe 60 Outer diameter, the specific size is selected according to the actual processing situation. The manipulator 20 referred to in the present invention is a manipulator with clamping and driving shaft workpiece rotation. This is an existing common technical means and should be understood by those skilled in the art , the material of the grinding sleeve 34 and the grinding bar 33 in the present invention should be reasonably selected according to the material of the pipe fitting 60 to be polished, for example, when the pipe 60 of 45 steel material is processed and the grinding sleeve 34 and the grinding bar prepared by diamond abrasives are selected. 33...

Embodiment 3

[0062] When the centrifugal equipment used for the inner surface treatment of pipes of the present invention is actually used: after the fastener 40 is sleeved on the outer surface of the pipe 60, the pipe 60 is pressed into the through hole on the base 10, which can be selected during the pressing process. The rubber hammer knocks the pipe material 60 to make it easy to enter the through hole in the base body 10, and then by tightening the nut on the outside of the clamping block 70, the gap between the clamping block 70 and the pipe material 60 is reduced during the nut tightening process, thereby To realize the clamping of the pipe material 60, after the positioning and clamping of the pipe material 60 are completed, the manipulator 20 clamps the grinding assembly 30 and drives the grinding assembly 30 to rotate to grind the inner wall of the pipe material 60, and after finishing the grinding process, the brushing assembly 50 pairs The inner wall of the pipe is oiled or pain...

Abstract

The invention discloses a centrifugal device for treating the inner surface of a pipe, and belongs to the technical field of pipe processing. The device comprises a base body and a mechanical arm; thebase body is provided with a through hole for placing the pipe; the mechanical arm is mounted on the base body and is used for clamping a polishing assembly and driving the polishing assembly to rotate to polish the inner wall of the pipe, and a gap between the pipe and the through hole in the base body is filled with a fastening piece; and the fastening piece comprises a first ring body connected to the outer wall of the pipe in a sleeving manner, the first ring body is connected with a coaxial second ring body, the upper and lower ends of the second ring body are unequal in diameter, the end with the smaller diameter is connected to the first ring body and is equal to the first ring body in diameter, the second ring body is divided into a plurality of segments from a notch, and a notchin the first ring body corresponds to the notch in the second ring body. According to the centrifugal device, in the process of treating the inner surface of the pipe, the vibration of the pipe is effectively reduced, the rate of adhesion between cleaning debris on the inner surface of the pipe and the inner wall of the pipe is low, and the quality of the inner surface of the processed pipe is high.

Description

technical field [0001] The invention belongs to the technical field of pipe processing, and in particular relates to a centrifugal device for treating the inner surface of pipes. Background technique [0002] In modern steel pipe production, more and more heat treatment is used to improve its strength, toughness or other specific performance. However, due to the high cost of the protective atmosphere heat treatment furnace, it is rare. However, due to the poor sealing of the furnace body and input and output devices in the current common steel pipe heat treatment furnace, the inner and outer surfaces of the pipe will be oxidized at high temperature during heat treatment, thereby forming dense oxide scales, which will affect the appearance and performance of the product. In order to obtain a smooth surface, there is usually a process of removing iron oxide scales on the inner and outer surfaces after heat treatment. The common ways to remove the iron oxide scale on the inne...
