[0027] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0028] First embodiment

[0029] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 ,in, Figure 1 This is a schematic structural diagram of a first embodiment of a high-precision machining device for titanium and titanium alloy coiled wire provided by the present invention; Figure 2 It is a structural diagram of the main body of the rack; Figure 3 It is a schematic diagram of the structure of the three-jaw chuck and the cooling nozzle; Figure 4 A high-precision machining device for titanium and titanium alloy coiled wires, comprising:

[0030] The frame body 1, the middle guide clamp, the rear guide clamp and the clamping wheel, the surface of the frame body 1 is installed with a first shell, the interior of the first shell is respectively provided with a front guide clamp and a cooling nozzle;

[0031] a second shell, the second shell being mounted on one side of the interior of the frame body;

[0032] The cutter disc is arranged at one end of the second shell, the middle guide clamp and the rear guide clamp are located at the other end of the second shell, and a connecting frame is arranged on the clamping wheel.

[0033] The first housing 6 and the connecting frame 8 are used for chip removal of the cutter head machine.

[0034] The cooling nozzle 9 is used to cool the cutter head 3 when in use.

[0035] The selection of cutterheads for machining titanium alloy coiled wire varies depending on the machining material, dimensional accuracy control, etc. The machining of high-precision coiled wire requires a surface roughness of Ra ≤ 1.6μm after machining. According to existing machining equipment, the cutterhead is installed at a 5° inclination angle. To ensure that the machining surface is the center line after the cutterhead is installed, the overall thickness of the machined cutterhead and gasket is determined;

[0036] Selection requirements for cutting discs for titanium alloy coiled wire. Carbide cutting discs (with chamfered edges) can help reduce cutting marks on the surface of titanium alloy wire.

[0037] The optimal machining speed for titanium alloy coiled wire is between 32m / min and 35m / min. The cutter head speed and machining speed have an important influence on chip removal and the surface quality of the machined wire.

[0038] Please refer to Figure 1 It was found that while ensuring smooth chip removal, the distance between the front and middle guide devices was shortened as much as possible to improve the wire guiding stability during machining.

[0039] (1) The leading jaw adopts a three-grip chuck and double roller structure. Under the premise of ensuring chip removal space, the distance between the leading jaw and the cutter is shortened as much as possible. Each jaw is equipped with a fine-tuning device to facilitate the adjustment of the center to ensure uniform processing of the raw material in one circle;

[0040] (2) The distance between the middle guide and the cutter is shortened, the middle and rear guide adopts a six-guide wheel structure, and the connecting rod is adjusted to further accurately position the tool, improve clamping stability, and ensure processing dimensional accuracy.

[0041] Please refer to Figure 2 It is learned that the assembly accuracy of the hollow spindle bearing can be improved to meet the high speed requirements of the titanium alloy coiled wire machine with cutter disc.

[0042] (1) The bearings are selected from medium and high speed angular contact precision matched bearings, and adopt the hot-installation process. The elastic preload eliminates the gap to ensure that the tightness is consistent in cold and hot states. The spindle end runout after assembly is ≤0.01mm;

[0043] (2) The main machine adopts a reinforced frame, which can meet the maximum speed of 3000r / min and the cutter head linear speed of 50m / min.

[0044] Please refer to Figure 3 It is learned that the chip removal effect of the cutter head machine can be improved and the size control of titanium alloy coiled wire can be achieved by machine processing.

[0045] Three sets of high-pressure cutting fluid nozzles are installed on the upper end of the cutter head guard. The nozzles are aimed at the machining position. The high-pressure cutting fluid helps to break chips and achieve cooling effect, prevents titanium chips from accumulating, and ensures the service life of the tool.
