Detailed Description
The invention will now be described in detail with reference to the accompanying drawings, in which the invention comprises the following steps:
(1) Winding the metal wire into a coil spring: winding the metal wire into a spiral spring with the outer diameter phi of 0.8-phi 1.3mm by a numerical control winding machine; the numerical control winding machine can adopt an SMM-208 numerical control winding machine; the metal of this example is 1Cr18Ni9Ti;
(2) Braiding by using a braiding tool:
a. 2 transverse struts and 2 longitudinal struts are adopted, the 2 transverse struts are parallel, the 2 longitudinal struts are also parallel, and the transverse struts are perpendicular to the longitudinal struts; the transverse supporting rod and the longitudinal supporting rod are fixed through a clamping block;
b. adjusting the outline size of a rectangle formed by the transverse supporting rod and the longitudinal supporting rod to a design size;
c. sequentially winding the spiral spring prepared in the step (1) among 2 transverse struts according to the longitudinal direction, then sequentially winding the spiral spring among 2 longitudinal struts transversely, and repeating the actions until the spiral spring is wound to a preset thickness to form a gasket blank;
(3) Pressing: filling the gasket blank into a mould for compression molding;
(4) Correcting and forming: the press formed arch liner is calibrated to ensure the dimensions, and measuring parts exceeding the acceptable dimensions allows for re-press forming.
When the braiding tool is used, the size is limited by the positioning block, then the screw is screwed down, then the positioning block is taken down to be braided according to the requirement, after braiding is completed, the screw is loosened, the steel wire is drawn out, and the braided blank is taken down; the positioning block is rectangular in outline, and four sides of the positioning block are abutted with the inner side of a rectangle formed by the 2 transverse supporting rods and the 2 longitudinal supporting rods.
The specific knitting method is as follows: fixing one end of the spiral spring prepared in the step (1) on a knitting tool, stretching the spiral spring into spiral spring rolls with the screw pitches of 0.8-1.5 mm, interweaving the spiral spring rolls transversely and longitudinally, winding the spiral spring rolls layer by layer on the tool, mutually meshing the screw pitches of the spiral spring rolls, and knitting the spiral spring rolls in a hooking way until the final tail part knitting is finished and then plugging the spiral spring rolls in a blank to finish the production of the liner blank;
after knitting is completed, removing the screws of the clamping blocks, extracting the transverse support rods and the longitudinal support rods, enabling the gasket blank to be an independent unit, and putting the single unit into a pressing tool for compression molding; the part is formed by pressing the whole blank part without joints, and the part has no broken ends, no loss and complete processing.
The liner processed by the method is an arch part, as shown in fig. 4, and the flange can be attached to a pipeline; when the engine pipeline assembly is subjected to vibration displacement, the dry friction damping of the arch-shaped liner can dissipate a large amount of energy to play a role in vibration reduction, so that the engine shell is protected from damage caused by pipeline abrasion.
