Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a titanium alloy blank cutting device. Background Art

[0002] Titanium alloy refers to a variety of alloy metals made of titanium and other metals. Titanium alloy is widely used in various fields due to its high strength, good corrosion resistance, high heat resistance and other characteristics. Pipe fittings are a common type of titanium alloy blanks. Before using the blank pipe fittings, the relatively long blank pipe fittings need to be cut into suitable lengths. Some existing cutting devices fix the pipe fittings from one or both ends, and the fixing position is far away from the middle cutting position. During the cutting process, especially when the pipe fittings are about to be cut, they are prone to deviation, which affects the cutting effect. Utility Model Content

A pressure plate is provided between the lower ends of the flat-headed vertical rods that are opposite to each other at front and rear. A spring is provided on the outer side of the flat-headed vertical rod and between the pressure plate and the square frame. A second roller shaft with a seat is provided at the lower end of the pressure plate, and a support rod is provided at the lower end of the square frame. A cutting shell is provided at the lower end of the support rod, and a cutting circular saw is rotatably connected to the inner side of the cutting shell. A second motor is provided at the upper end of the inner cavity of the square frame, and a belt is used to transmit the output end of the second motor to the cutting circular saw.

[0005] Compared with the prior art, the beneficial effects of the utility model are as follows: the titanium alloy blank pipe is supported by the first roller with a seat, so that the position of the pipe is adjusted to correspond to the cutting position. When cutting, as the top plate and the square frame move downward, the second roller with a seat will first press down on the pipe to clamp and fix the pipe. As the spring is further compressed, the pressure on the pipe is gradually increased, and the clamping position is close to the cutting position of the pipe to ensure the pressure and fixation effect of the pipe. Then the cutting circular saw contacts the upper end of the pipe for cutting, and then the clamped pipe is driven to rotate by the rotation of the roller with a seat, and the pipe is circularly cut to ensure the cutting effect.
