[0002] At present, there are two methods for producing container lashing rods: one is to use the rod material with the same diameter as the node to be turned into a joint rod, and then the joint rod is connected to the long rod through threads. Using this method will cause a lot of waste of materials and high production costs. , and the connection part is loose, easy to corrode and rust; the second is to forge the rod material slightly smaller than the diameter of the node, and then roll the part between the two nodes thin, and then weld the joint rod and the long rod. The pressing power is large, and the production cost is high

Embodiment Construction
[0012] With reference to the accompanying drawings, the container lashing bar is made up of two parts, a joint bar 1 and a long bar 2 . The mold used when manufacturing the binding bar includes a push rod 3, a mold box 4, a front mold 5 and a back mold 6. The push rod 3 is installed on the upper workbench 7 of the press, and the mold box 4 is installed on the lower workbench of the press. The mold box 4 is provided with a front mold 5 and a rear mold 6. The front mold 5 is a split structure consisting of two left and right split molds. Each split mold has a semicircular opening. When the two split molds are closed , forming a cylindrical chamber. Die 10 is installed in the back mold 6, and mold 10 is provided with a cavity 9, and cavity 9 is consistent with the node shape of binding rod finished product, and back mold 6 afterbody is screwed with metal rod end positioning device 8. The end positioning device 8 is provided with a screw rod that can move horizontally back and f...

The invention discloses a method for manufacturing a container lashing rod and a mold used therefor. The metal rod (11) with the diameter of the long rod (2) of the finished lashing rod is used as a raw material, and the metal rod (11) is placed around the first node position in the middle of the metal rod (11). Heating at a fixed length, and then installing a mold with a metal rod end positioning device at the node with a cavity that matches the shape of the node, and simultaneously positioning the rod of the metal rod (11), using a press to push from the node to the rod The die forges the first node; after the first node, the second node is determined according to the distance between the two nodes of the binding rod, and the second node is forged according to the method of the first node; all nodes are forged and processed according to the above method. Adopting this method will not cause waste of raw materials and reduces production cost; each node is forged in stages, the pressing power is small, and energy consumption is reduced.
Description
technical field [0001] The invention relates to a manufacturing method of a container lashing rod and a mold used therefor. Background technique [0002] At present, there are two methods for producing container lashing rods: one is to use the rod material with the same diameter as the node to be turned into a joint rod, and then the joint rod is connected to the long rod through threads. Using this method will cause a lot of waste of materials and high production costs. , and the connection part is loose, easy to corrode and rust; the second is to forge the rod material slightly smaller than the diameter of the node, and then roll the part between the two nodes thin, and then weld the joint rod and the long rod. The pressing power of this method is large, and the production cost is high. Contents of the invention [0003] The invention provides a method for manufacturing a container binding bar with low production cost and a mold used therefor. [0004] The present inve...
