Embodiment 1

[0023] Embodiment 1: A kind of preparation method of the temperature rise elastic force automatic compensation titanium spring of pneumatic friction clutch brake, comprises the following steps:

[0024] The first step is to select and determine the phase transition point of the TiNi alloy as 64°C according to the characteristic that the elastic force of the ordinary spring will gradually decrease when the temperature rise is equal to or greater than 65°C;

[0025] The second step uses a differential scanning calorimeter (DSC) to measure the actual phase transition point of the selected TiNi alloy material;

[0026] In the 3rd step, the TiNi alloy that the phase transition point is determined in the second step is cold-drawn into a round wire equal to the diameter of the conventional spring wire used;

[0027] The fourth step is to wind the round wire drawn in the third step into a spring according to the inner diameter or outer diameter and pitch of the conventional spring;

Abstract

The invention relates to a method for preparing a temperature rise elastic force automatic compensation titanium spring of a pneumatic friction clutch brake. The method comprises the following steps of: 1, selecting and determining the range of phase transformation points of a titanium alloy; 2, measuring the phase transformation points of the selected titanium alloy material; 3, cold drawing the titanium alloy for filamentization; 4, winding to form a spring; 5, cutting, and processing the two ends of the spring to form planes; 6, putting the titanium spring into a furnace, heating, and preserving heat; and 7, cooling. The method has a simple preparing process, and the titanium spring is convenient to mount and use. When the pneumatic friction clutch brake is designed and manufactured, heat dissipation area and heat dissipation openings are not required to be increased specially. In the summer which has an extremely low heat dissipation effect and is extremely hot, instant clutching and quick braking of a clutch can be ensured. Therefore, the method is extremely high in development value and application value during actual application.

Description

technical field [0001] The invention relates to a preparation method of a titanium spring with automatic temperature rise elastic force compensation, in particular to a preparation method of a pneumatic friction clutch brake automatic temperature rise elastic force compensation titanium spring. Background technique [0002] Pneumatic friction clutch brakes are very suitable for engagement, separation and braking of transmission systems such as forging equipment, printing machinery, textile machinery, and papermaking machinery operated remotely, especially for matching with high-speed numerical control machinery. Such as high-speed CNC presses, due to the high speed and high inertia, the clutch must have the performance of instant clutch and fast braking. Otherwise, not only equipment accidents are extremely prone to occur, but also personal safety accidents of operators are extremely prone to occur. However, after the exhaust of the pneumatic friction clutch brake, the pist...
