Problems solved by technology

[0002] Most of the existing steel wire rope fastening equipment adopts U-shaped frames. A new type of U-shaped elastic wire rope fastening device with guide holes has been disclosed (authorized announcement number CN 201049449Y, patent number ZL 200720148797.5). The U-shaped frame is manufactured by welding technology. , complex manufacturing process, poor strength
The overall force of the U-shaped frame is uneven, the stressed parts are easy to wear, and the service life is short
The existing U-shaped steel wire rope fastener frame is prepared by welding steel plates after bending. The preparation process is complicated and the operation is difficult.
There are welds in the frame, the overall frame strength is poor, and the service life is limited
In addition, the welding process is required in the preparation of the frame, which not only pollutes the environment but also requires high energy consumption.
The finished product rate of bending and welding process is only 50-60%. Inadequate bending and welding is the direct cause of high scrap rate

Abstract

The invention relates to the technical field of preparation of steel wire rope fastening equipment, in particular to a manufacturing method of a seamless frame of a steel wire rope fastening device. The method comprises steps including preheating treatment, rolling treatment, cooling treatment, heat treatment, punching treatment and cutting treatment. The finished product frame prepared through the manufacturing method adopts a seamless integrated structure, the whole frame is evenly stressed, stress concentration is avoided during stressing, and the whole frame is firmer in structure and safer and more reliable to use. A seamless steel pipe is used as a raw material directly and is a common standard part. The raw material is cheap and easy to obtain, and the machining cost is low. The manufacturing method adopts the multi-stage graded rolling technology and is simple to operate and low in implementation difficulty, the frame can be machined to the designed size conveniently and is not welded by a welding machine, and the energy consumption is substantially reduced. Meanwhile, damage of welding to material properties is also reduced.
