Groove pipe cutting all-in-one machine

Abstract

The invention discloses a groove pipe cutting all-in-one machine, which is characterized in that a rack is provided with a spindle, a cutter feed servo motor is fixedly arranged on the rack, a cutter rotating disk is connected with the spindle, and a cutter feed shelter is concentric with the cutter rotating disk; a transmission redirection component is arranged between the cutter feed shelter and a cutter mobile device, and the cutter rotating disk is provided with 2-4 cutter mobile devices; the front and the back of the rack are respectively provided with a clamping mechanism, and 3-6 jaws are evenly distributed on grip slippers in the front and the back clamping mechanisms respectively; and a clamping jaw, a guide rail and a horizontal expansion device are arranged in a beam above the rack and a support, and the clamping jaw is internally provided with a vertical expansion device, a guide rail and a pair of clamping jaws. By using the machine provided by the invention, the relativeangular velocity difference generated between the cutter feed shelter and the cutter rotating disk can be kept constant, and the cutter feed is stable and the movable position of the cutter can be accurately controlled, thus realizing groove manufacturing in different forms; and the cutter is not easy to damage, thereby ensuring even cutting speed and feed speed, and guaranteeing the groove manufacturing of a steel tube with different wall thicknesses.

Description

Technical field: [0001] The invention relates to a mechanical device, in particular to an integrated machine which simultaneously completes cutting and beveling of steel pipes, and particularly relates to its mechanical structure. Background technique: [0002] The common method of steel pipe cutting and groove processing is to cut the raw material pipe to a fixed length first, and then perform groove processing. Cutting to length is usually done with band saw cutting and flame or plasma cutting; beveling is usually done with end bevel machining or flame or plasma cutting. Such traditional processing methods have disadvantages such as long production cycle, low efficiency, high cost, high labor intensity, and environmental pollution. In order to solve these problems, both at home and abroad are studying the process of cutting and beveling steel pipes with metal cutting tools at the same time. Both ends of the steel pipe are clamped in the middle and cut simultaneously with ...

AI Technical Summary

Problems solved by technology

In the above-mentioned cutting mechanism, 1) when the load changes, the spindle speed changes accordingly, and it is difficult to control the tool walking speed to follow the change, and it is impossible to accurately control the moving amount of the tool, especially when the pipe wall is thick and the material is uneven. For steel pipes, the tool may be damaged due to the uneven feed rate; 2) Since the current position of the tool travel motor cannot be detected in real time, it is difficult to accurately control the tool feed depth, and U-shaped, double-V-shaped grooves cannot be processed; 3 ) The tool feed device determines that thick-walled steel pipes cannot be processed; 4) Since the tool feed transmission mechanism including the tool stroke motor is installed on the spindle turntable, the spindle turntable is biased, even if the counterweight is increased, the weight of the spindle turntable will increase, which is not conducive to improving The speed of the spindle turntable affects the processing efficiency

Therefore, it is only limited to the processing of pipes with thin wall thickness, the groove processing type is single, and the processing efficiency is relatively low. At present, the steel pipe cutting and beveling equipment at home and abroad can ensure that different wall When thick and different types of grooves are used, it is difficult to ensure that the tool is damaged due to unstable movement and unstable control, and it is difficult to realize the processing of large wall thickness and different types of groove steel pipes
