Description

Technical Field

[0001] The invention relates to the technical field of titanium alloy pipeline processing, and in particular to a titanium alloy pipe cutting device. Background Art

[0002] During the production process, the titanium alloy tube needs to be cut to the required length. In the prior art, the adjustment mechanism is generally moved according to the size of the titanium alloy tube to initially limit the position, and then the two ends of the titanium alloy tube are fixed by a clamping mechanism, and then the fixed titanium alloy tube is cut by a cutting machine; since the titanium alloy tube is a thin-walled structure, high temperature will be generated at the contact part between the cutting tool and the titanium alloy tube during the cutting process. The thermal conductivity of titanium alloy is poor, and the heat generated during cutting is concentrated in a smaller area, which will reduce the strength of the cut part. In addition, no supporting structure is set inside the titanium alloy tube, and the inner diameter of the cutting part lacks supporting force. The elastic modulus of titanium alloy is low, which makes the titanium alloy easy to deform at the cutting position when subjected to radial force, affecting the cutting quality of the titanium alloy tube.

[0003] In addition, during the cutting process of titanium alloy pipes, the high-speed rotation of the cutting tool causes the temperature of the cutting tool to gradually increase, and heat accumulates in the cutting area. The high temperature causes the chips to adhere to the blade surface, which is easy to cause wear on the tool. The continuous accumulation on the cutting tool may cause the cutting surface of the titanium alloy pipe to be rough and not smooth. Summary of the invention

[0051] The present invention provides a titanium alloy pipe cutting device, wherein an inner support assembly is arranged inside the titanium alloy pipe, and the inner support assembly includes two single support mechanisms connected by a telescopic cylinder. After the rotary clamping assembly clamps the titanium alloy pipe, the single support mechanism close to the rotary clamping assembly is adjusted to support the titanium alloy pipe on one side of the cutting position. After the telescopic cylinder is extended and retracted, the other single support mechanism is driven to move to the other side of the position to be cut, thereby supporting the inner walls of the titanium alloy pipe on both sides of the cutting position to avoid deformation of the cutting opening after cutting. The titanium alloy pipe is clamped by the rotary clamping assembly, and the matching assembly is adjusted according to the length of the titanium alloy pipe to match and support the end of the titanium alloy pipe. At this time, the titanium alloy pipe is mounted under the mobile cutting assembly. According to the position to be cut, the mobile cutting assembly is adjusted to move to the cutting position, and the position of the cutting head is adjusted. At the same time, the telescopic cylinder is adjusted. The telescopic cylinder drives the rotary clamping assembly and the clamped titanium alloy pipe to rotate synchronously to facilitate the cutting of the titanium alloy pipe by the cutting head.

[0052] The present invention provides a titanium alloy pipe cutting device, which clamps titanium alloy pipes with different cross-sectional shapes by rotating four clamping plates evenly spaced along the circumferential direction in the clamping assembly. The clamping plates are synchronously driven by clamping screws and have strong applicability. At the same time, the single support mechanism in the internal support assembly includes a toothed plate, and the toothed rods arranged on the two upper and lower toothed plates are relatively arranged and meshed with the synchronous gear ring at the same time, and the toothed rods arranged on the two left and right toothed plates are relatively arranged and meshed with the synchronous gear ring at the same time. The two upper and lower toothed plates and the two left and right toothed plates all move synchronously in reverse, so that the abutment wheels connected to the toothed plates can be suitable for titanium alloy pipes of various shapes and sizes.

[0053] The present invention provides a titanium alloy pipe cutting device, wherein an atomizing nozzle is arranged on the cutting head, one end of the atomizing nozzle is connected to a cutting fluid tank, and the other end is connected to an inert gas. The cutting fluid tank stores cutting fluid. When cutting the titanium alloy pipe, the cutting fluid and the inert gas are mixed in the atomizing nozzle and then sprayed on the cutting position of the titanium alloy pipe through the atomizing nozzle, thereby providing a protective atmosphere for the cutting of the titanium alloy pipe and avoiding the use of a large amount of cutting fluid. After the cutting fluid evaporates and absorbs heat, it can quickly cool the cutting area, thereby reducing the adhesion of chips to the cutting head and greatly improving the cutting quality of the titanium alloy pipe.
