Description

A shackle blank making device

Technical field

The invention relates to the field of automated processing, specifically a shackle blank making device.

Background technique

Shackles can be used in various occasions for lifting operations, such as ports, docks, cargo stations, warehouses, military industry, metallurgy, aerospace and other places. The shackle is U-shaped as a whole. In order to ensure that the shackle has a higher connection strength, the connection between its two ends should not be formed by a bent structure, but holes should be made directly on the workpiece. In the production process of large shackles, bar-shaped round steel is usually used as the raw material to ensure that the end of the shackle is easy to open and the opening has sufficient strength. Therefore, it is necessary to process the end of the round steel first so that the annular part formed after the hole is expanded has a large enough diameter, otherwise it will affect the quality of the final processed workpiece.

For the aforementioned process, the deformation treatment of the end of the round steel is often processed manually combined with mechanical equipment. First, the bar-shaped round steel is heated, and then the staff transfers the bar-shaped round steel to a platform that is convenient for processing, and uses equipment such as air hammers to process the heated round bar. Because both ends of the round steel need to be deformed, the cooperation of two workers is required. On the one hand, this operation requires a certain degree of proficiency on the part of the staff, and on the other hand, it also requires a good tacit understanding between the two staff members to complete it. These reasons make processing operations more difficult, which not only affects the yield and quality of workpieces, but also affects the efficiency of workpiece processing.

This ensures a sufficiently long feeding distance. Each level of feeding assembly includes a feeding cylinder 12, and the feeding cylinder 12 can be a pneumatic cylinder, a hydraulic cylinder or an electric push rod. Since the weight of the bar-shaped round steel itself is not high, a more flexible and lower-cost cylinder can be selected as the feeding cylinder 12. By stacking two feeding cylinders 12 one above the other, a feeding assembly is formed, in which the cylinder shell of one feeding cylinder 12 is fixedly connected to the movable end of the other feeding cylinder 12 . Thereby, one feeding cylinder 12 is used to push the other feeding cylinder 12 to move, and the movable end of the pushed feeding cylinder 12 is used as a push rod to push the round steel for feeding.
