Production manner null of vibration-proof rubber lamp foot

摘要

PURPOSE: To integrally mold the fitting part and the fixing part for other members, of a vibration proof rubber bush, by cutting a long bracket material produced through an extrusion process and bending the joint part. ;CONSTITUTION: The mount bracket 1 is constituted of a cylindrical part 2 and the joint part 3 which is extended to both front and rear side along the axial line of the cylindrical part. The vibration proof rubber bush 7, which consists of an inner cylinder 4 and an outer cylinder 5, which are made of metal, and the rubber part 6 which is adhered with valcanization between both the cylinders, is fitted in the inner peripheral surface of the cylindrical part 2. This cylindrical part 2 and the joint part 3 which is fixed on other members with bolts, etc., are integrally extruded. The extruded article is then cut at equal intervals apart in the direction crossing the extruding direction. The constricted part 9 of the joint part is twisted at an angle of 90 degrees, the joint part is made parallel to the axis line of the cylindrical part 2, bolt holes 8 are made and the product is complete. Thus, the fitted part and the fixing part are integrally formed, and the degree of freedom in setting the position of the joint part is raised.;COPYRIGHT: (C)1993,JPO&Japio
