Blanking production line and feeding method for large size anchor chain bar

Abstract

The invention discloses a blanking production line for a large size anchor chain bar. The blanking production line comprises a material loading device, a power material transporting frame, a sawing machine, an overhead hoist and an electric track flat car. A material loading frame and the material transporting frame are arranged side by side. The overhead hoist comprises a lifting appliance, a lifting appliance hanging frame and an anchor chain bar material carrying frame. The sawing machine is arranged between the power material transporting frame and the lifting appliance hanging frame. Theanchor chain bar material carrying frame is located inside the lower portion of the lifting appliance hanging frame. The electric track flat car is located outside the other end of the lifting appliance hanging frame. A use method is as follows: (1) the whole long bar is turned onto the power material transporting frame; (2) the whole long bar is sawed for blanking according to the set length; (3)the anchor chain bar is hoisted into a groove-shaped material frame; and (4) the groove-shaped material frame is carried away by the electric track flat car. By means of the blanking production lineand feeding method for the large size anchor chain bar, the material dividing and material transferring actions are accurate and reliable, and the continuous automatic conveying from the whole long bar to the anchor chain bar after sawing is achieved according to the feeding method, so that the production efficiency is improved, the labor intensity of workers is reduced, and the surface quality ofthe anchor chain bar is improved.

Description

technical field [0001] The invention relates to a sawing and blanking production line for round steel bars, in particular to a sawing, blanking and lifting production line for anchor chain round steel bars required for the production of chain links of anchor chains, which belongs to the primary metal profile field of processing technology. Background technique [0002] Anchor chains are used for the mooring of ships and marine engineering equipment on the water, and are important components related to the safety of ship navigation and sea operations. Large-scale anchor chains refer to those with a cross-sectional diameter of the longitudinal end of the anchor chain ring with a diameter of Φ150mm to 200mm. anchor chain. Modern anchor chains are electric welded anchor chains, which use induction heated round steel bars to bend into long circles on electric welding anchor chain manufacturing units, and then flash welded to make anchor chain rings. The anchor chain steel is a ...

AI Technical Summary

Problems solved by technology

This production process has the following disadvantages: the rising speed of the whole length of the bar is relatively slow, and after sawing a whole length of the bar, it is necessary to wait for the second whole length of the bar to be turned over to the feeding rack, resulting in low production efficiency, The labor intensity of workers is high, and it is easy to damage the surface of the anchor chain bar, which affects the product quality of the final anchor chain ring; it is also easy to damage the trough-shaped material rack, which needs to be repaired, which is time-consuming and labor-intensive, and increases the use cost of the production line
