Production device for lead sinker

Abstract

The invention provides a production device for a lead sinker. The production device for the lead sinker comprises a lead ingot casting device used for casting lead raw materials into a lead ingot, a lead pipe extrusion-forming die used for extruding the lead ingot into a hollow lead pipe, and a lead particle hobbing device used for cutting the lead pipe into lead particles. The lead pipe extrusion-forming die comprises a female die body and a male die body. A cylindrical channel is formed in the female die body. The male die body is arranged above the female die body in a liftable mode througha guide device. A cylindrical rod which corresponds to the center of the cylindrical channel of the female die body and stretches into the cylindrical channel of the female die body is formed on themale die body. The lead particle hobbing device comprises a cutting device and a feed device. According to the production device for the lead sinker, after the raw materials are cast into the lead ingot through the lead ingot casting device, the lead ingot is extruded into the hollow lead pipe through the lead pipe extrusion-forming die, and finally, the lead pipe is cut into the lead particles through the lead particle hobbing device, so that the lead sinker is manufactured. By adoption of the production mode, the required die is simple in structure, operation is easy and convenient, the operation difficulty is low, demolding is not needed, discharging can be conducted automatically, the production efficiency can be greatly improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of fishing tool production, in particular to lead sinker production equipment. Background technique [0002] Fishing nets are suitable for fishing at sea, in rivers and reservoirs, and are one of the traditional fishing tools. The upper part of the fishing hanging net is connected with wooden or plastic floats at a certain distance, the middle is a wire mesh made of highly transparent nylon nylon yarn, and the lower part is a heavy sinker. The entire net is 30 to 50 meters long. When the net is laid out in the water, the floater uses its buoyancy to lift the net upwards, and the sinker uses its weight to sink down, so that the net is opened up and down, and the fish can easily be entangled and caught after touching the net. [0003] In the prior art, the sinker is generally made of metal lead, and the production method generally adopts mold direct molding. Since the sinker is a hollow structure, the general...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the sinker is generally made of metal lead, and the production method generally adopts mold direct molding. Since the sinker is a hollow structure, the general mold structure is complicated, the operation is cumbersome, and it is inconvenient to demould, and the one-time mold production The number of sinkers is small and the production efficiency is low
