Automatic concatenation knitting-on method and apparatus for metal smith forging circular chain

Abstract

The invention relates to a production method of a metal chain ring, in particular to an automatic tandem connection and knitting method of a circular ring chain forged with metal and a device thereof. The method has the following steps: a bent ring bar stock is automatically delivered into a chain bending mechanism, and gripped by a mechanical hand, and first bent to be U-shaped under the effect of left and right chain bending rollers; the U-shaped ring penetrates into two knitted and forged rings and is delivered to a core die through the functions of the mechanical hand, a delivering chain inlet and outlet batch bin mechanism, and a core die mechanism; according to the shape of the core die, the U-shaped ring is automatically bent into the circular ring chain with only one step, thereby the tandem connection and the knitting of the circular ring chain is completed. Then an upper core die is elevated and opened, the mechanical hand takes out the well bent ring chain from the core die, the delivering chain inlet and outlet batch bin mechanism lowers and delivers out the well knitted chain, so that the next bent ring bar stock enters into the chain bending mechanism, and automatic repeating and circulation are continued. The invention proposes the automatic tandem connection and knitting method of the circular ring chain forged with metal with mechanical-electric-hydraulic integration and the device thereof, thereby having the advantages of high production efficiency, stable product quality, high degree of automation, and safe and reliable production process.

Description

technical field [0001] The invention relates to a production method of metal chain links, in particular to a method and a device for automatic serial connection and knitting of metal forged round link chains (compact chains). Background technique [0002] Metal forged round link chains are also called compact chains because of their compact shape and structure, good strength, reliability, and high precision, so they are gradually used by large-scale mining equipment. Because metal forged round link chains are all large-scale chains (the wire diameter is more than 38mm), the inner width is compact, the shape is large, and the weight is heavy, so it is quite difficult to manually connect and knit in series. Therefore, at present, the production of domestic forged circular link chains is completed by imported automatic series connection and weaving equipment, and there is no automatic series connection and weaving equipment for this product in China at present. At present, th...

AI Technical Summary

Problems solved by technology

Because metal forged round link chains are all large-scale chains (the wire diameter is above 38mm), the inner width is compact, the shape is large, and the weight is heavy, it is very difficult to manually operate the series connection

Therefore, at present, domestic production of forged round link chains is completed by imported automatic series knitting equipment, and there is no automatic series knitting equipment for this product in China.

At present, this kind of imported equipment is large in size, complex in structure, and expensive, and it is difficult to maintain and replace other parts, which is unaffordable for general manufacturers.
