The invention provides an extrusion method for manufacturing a taper sleeve. The extrusion method for manufacturing the taper sleeve comprises the following steps: downwards moving a press to press a first upper die; penetrating the upper end, which is extruded, of a first steel tube through a cavity of the first upper die from the inside of a die sleeve and extending the upper end of the first steel tube into a second steel tube; placing a second upper die on the first upper die, and downwards moving the press to extrude the upper end of the first steel tube; placing a third upper die on the second upper die, and downwards moving the press to extrude the upper end of the first steel tube; connecting the lower part of the die sleeve to a first lower die, downwards moving the press, and extruding the lower end of the first steel tube by using the first lower die; and placing a second lower die under the first lower die, and downwards moving the press to extrude the lower end of the first steel tube to obtain the taper sleeve. Extrusion procedures of the extrusion method are simple, the extrusion method is convenient to operate, and production efficiency is improved. By the extrusion method, the formed taper sleeve is high in precision, correspondingly, stresses on the extruding dies are small, and the service life is prolonged remarkably.
Description
technical field [0001] The invention belongs to the field of elevators, in particular to an extrusion method for making a taper sleeve. Background technique [0002] An elevator is a moving device used to carry a certain load. It generally includes a traction suspension cable (or traction suspension belt) that acts as a traction medium and suspension. When implementing it, it is necessary to fix the two ends of the suspension belt or suspension cable to the On the load-bearing structural components corresponding to the elevator. For the fixing of the head of the suspension belt, a wedge joint device is usually used. Pass the suspension belt through the suspension belt guide groove on the mating surface of the tapered sleeve and the wedge, and under the gravity of the load of the suspension belt, the suspension belt is clamped between the wedge sleeve and the wedge. The molding quality and strength of the taper sleeve is one of the important elements to ensure the safe oper...
