Description

Shackle blank making device

Technical Field

The invention relates to the field of automatic processing, in particular to a shackle blank making device.

Background

The shackle can be used for hoisting operations in various occasions, such as ports, wharfs, goods stations, warehouses, military industry, metallurgy, aerospace and the like. The shackle is U-shaped as a whole, and in order to ensure that the shackle has higher connection strength, the connection part of the two ends of the shackle is often not formed by adopting a bending structure, but is directly perforated on a workpiece. In the process of manufacturing a large shackle, strip-shaped round steel is usually selected as a manufacturing raw material, so that the end of the large shackle is convenient to open, and the open hole has enough strength. It is necessary to first treat the end of the round steel so that it expands to a sufficiently large diameter for the annular portion formed after the opening, otherwise it is turned back to affect the quality of the finished workpiece.

In the above-described steps, the deformation treatment of the round steel end portion is often performed by manually combining mechanical equipment. Firstly, heating the strip-shaped round steel, then transferring the strip-shaped round steel to a platform convenient to process by a worker, and processing the heated round steel by using equipment such as an air hammer. Because both ends of the round steel are subjected to deformation treatment, two workers are required to cooperate. This operation requires on the one hand a certain skill of the staff and on the other hand a very good degree of default of the two staff. These causes have made the difficulty of the machining operation extremely high, and affect both the yield and quality of the work and the working efficiency of the work machining.

The device of this scheme still includes transport mechanism 5 and snatchs mechanism 3, and transport mechanism 5 sets up the ejection of compact side at heating mechanism 2, carries out the feed and the ejection of compact of round steel to forming mechanism 4 through transport mechanism 5. The grabbing mechanism 3 is arranged on the discharging side of the heating mechanism 2 and is used for grabbing the strip-shaped round steel pushed out of the heating mechanism 2 by the feeding mechanism 1 onto the transferring mechanism 5.

The device forms the assembly line type production device capable of processing the strip-shaped round steel into the shackle blank through the combination of the mechanisms. The links of manual participation are reduced, so that the labor is saved, and the potential safety hazard problem in the traditional process is eliminated. Meanwhile, the quality of the shackle blank after the machining is finished and the production and machining efficiency are improved.

On the basis of the above embodiment, the feeding mechanism 1 of the present apparatus adopts a structure in which a multistage feeding assembly is provided on the upper side of the feeding table 11, and is gradually advanced in a stepwise structure by the multistage feeding assembly, thereby ensuring that a sufficiently long feeding distance is obtained. Each stage of feeding assembly comprises a feeding cylinder body 12, and the feeding cylinder body 12 can be an air cylinder, a hydraulic cylinder or an electric push rod. Because the bar-shaped round steel has low self weight, a cylinder which is flexible and low in cost can be selected as the feeding cylinder body 12. By stacking two feed cylinders 12 one above the other, a set of feed assemblies is formed, wherein the cylinder housing of one feed cylinder 12 is fixedly connected to the movable end of the other feed cylinder 12. Thereby realizing that one feeding cylinder body 12 pushes the other feeding cylinder body 12 to move, and the movable end of the pushed feeding cylinder body 12 is used as a push rod for pushing round steel for feeding. Two groups of four feeding cylinder bodies 12 are arranged on the feeding base table 11, two groups of four feeding cylinder bodies are formed, and feeding of two round steels can be achieved simultaneously. The feeding of round steel into the heating mechanism 2 can be accomplished by combining the same set of two feeding cylinders 12.
