A method of making a wedge sleeve

Abstract

The invention relates to the field of rope fixing sleeves, and discloses a manufacturing method of a taper clamping sleeve. The manufacturing method of the taper clamping sleeve comprises the following steps: S1, cutting out a hollow cylinder and taking the hollow cylinder as a substrate; S2, forming two opposite through holes for embedding nuts in the left side wall and the right side wall of the substrate; S3, carrying out extrusion necking on one end of the substrate for the first time; S4, carrying out extrusion necking on the end of the substrate for the second time, wherein the length of second-time extrusion necking is not greater than that of first-time extrusion necking; S5, flattening the substrate by extruding the left side and the right side of the substrate and enabling the width of the flattened substrate to be consistent to that of each nut; S6, trimming the edge of a lower part, except a second-time extrusion necking part, of the substrate, wherein two ends of a formed notch are arc-shaped; and S7, embedding the nuts in the substrate. Compared with a production technology for manufacturing a taper clamping sleeve by casting procedures, the manufacturing method of the taper clamping sleeve has few work procedures, greatly improves production efficiency, and meanwhile reduces production cost.

Description

technical field [0001] The invention relates to the field of cable fixing sleeve combinations, in particular to a manufacturing method of a wedge sleeve. Background technique [0002] The traditional wedge sleeve device is to fix the pin on the rope sleeve to the specified position of equipment such as crane or grab bucket, and the steel wire rope is wound on the wedge and passed in the tapered hole of the rope sleeve. Its shortcoming is that the angle between the center line of the tapered hole on the rope sleeve and the center line of the pin shaft is too small, so that when the wedge with the wire rope is inserted into the tapered hole of the rope sleeve, it will touch the fixed plate, and every time the wire rope is assembled or disassembled, the pins and wedges on the rope sleeve will be removed together, which is time-consuming and laborious. [0003] In recent years, the comfort, speed, safety devices and various mechanical properties of elevators have been continuou...

The disadvantages of the hoisting cable fixing sleeve used in the existing elevators are that it is inconvenient to install, there is a hidden danger of loosening, and it is difficult to meet the safety requirements of the elevator
