Problems solved by technology

[0002] The push cylinder device in the prior art generally drives the cutter to rotate through the push rod to rotate for cutting. In order to prevent vibration when the push rod rotates at high speed and affect the processing accuracy of the seamless pipe, the speed of the push rod is generally controlled below 400r / min , resulting in a small amount of cutting by the cutter and low production efficiency
In order to improve production efficiency, nowadays, the seamless pipe can be reversely rotated relative to the chip knife to increase the cutting amount of the cutting knife during cutting processing, but the production efficiency is only increased by 10%, and the effect is still not ideal.

Embodiment 1

[0018] figure 1 A seamless pipe inner wall processing device according to the first embodiment of the present invention is schematically shown.

[0019] Such as figure 1 As shown, the device includes a push rod 1 , a cutting knife 2 and a drive motor 3 . In addition, a guide bracket 4 and a finishing workpiece 5 are also included.

[0020] The push rod 1, the driving motor 3 and the cutting knife 2 are connected in sequence. The push rod 1 is fixedly connected with the drive motor 3 and can push the motor 3 . The driving motor 3 can drive the cutting knife 2 to rotate. The cutter 2 is slipped through the drive motor 3 and built into the seamless pipe 6 together. The guide bracket 4 and the finishing workpiece 5 are located on the drive motor 3 .

[0021] The drive motor 3 can be an electric motor, an air motor or a hydraulic motor. In this embodiment, the latter is the latter. The hydraulic motor has the advantages of large power, long life, small volume and large torqu...

Embodiment 2

[0028] figure 2 A seamless pipe inner wall processing device according to the second embodiment of the present invention is schematically shown.

[0029] Such as figure 2 As shown, the difference between this embodiment and the first embodiment is that: the finishing workpiece 5 is a rolling bearing. When processing the seamless pipe 6, the finishing workpiece 5 moves along with the drive motor 3, and the cut part of the seamless pipe 6 can be rolled, which improves the wear resistance, corrosion resistance and corrosion resistance of the inner wall of the seamless pipe 6 after cutting. compatibility.

[0030] When the present embodiment is used, the seamless pipe 6 to be processed is clamped and fixed by the chuck 7 of the machine tool. The driving motor 3 is built into the processing starting end of the seamless pipe 6, and one end thereof is fixedly connected with the push rod 1 . Start the motor that drives the chuck 7 of the machine tool, so that the chuck 7 of the ...

Abstract

The invention discloses a device for machining the inner wall of a seamless tube. The device for machining the inner wall of the seamless tube comprises a push rod, a cutter blade capable of being arranged in the seamless tube and a driving motor which can be arranged in the seamless tube and can be used for driving the cutter blade to rotate, wherein the push rod, the driving motor and the cutter blade are connected in sequence. The device for machining the inner wall of the seamless tube has the advantages that the cutting capacity of the cutting blade can be effectively improved and the production efficiency is quite high.

Description

technical field [0001] The invention relates to a processing device, in particular to a processing device for the inner wall of a seamless pipe. Background technique [0002] The push cylinder device in the prior art generally drives the cutter to rotate through the push rod to rotate for cutting. In order to prevent vibration when the push rod rotates at high speed and affect the processing accuracy of the seamless pipe, the speed of the push rod is generally controlled below 400r / min , resulting in a small amount of cutting by the cutter and low production efficiency. In order to improve production efficiency, nowadays, the seamless pipe can be reversely rotated relative to the chip knife to increase the cutting amount of the cutting knife during cutting. However, the production efficiency is only increased by 10%, and the effect is still not ideal. Contents of the invention [0003] The object of the present invention is to provide a seamless pipe inner wall processing...
