A creasing device

Abstract

The invention particularly discloses an indentation device, which comprises a base, wherein the base is provided with a left support and a right support in parallel, the lower parts of the left support and the right support are respectively and fixedly provided with a first bearing seat and a second bearing seat, a lower rotating shaft is movably arranged between the first bearing seat and the second bearing seat, one end of the lower rotating shaft is provided with a lower wire rolling wheel, the left support and the right support on the upper parts of the first bearing seat and the second bearing seat are provided with a chute respectively, a third bearing seat and a fourth bearing seat are respectively and slidably clamped in the chutes on the left side and the right side, an upper rotating shaft is movably arranged between the third bearing seat and the fourth bearing seat, and the end part of the upper rotating shaft on the same side with the lower wire rolling wheel is provided with an upper wire rolling wheel. The indentation device has the beneficial effects that indentation is uniform and fast, safety and practicability are realized, and active agent is uniformly added to the surface of a welding wire and added into the welding wire because uniform indentation grooves are formed on the surface of the welding wire.

Description

(1) Technical field [0001] In particular, the invention relates to an indentation device. (2) Background technology [0002] As an efficient welding process, gas shielded welding has the advantages of high production efficiency and low overall cost, and has been widely used in various fields of welding. However, due to CO 2 The nature of the gas itself causes a large amount of spatter during the welding process, which reduces the deposition efficiency and makes it difficult to guarantee the welding quality; especially for CO 2 Gas-shielded welding solid copper-plated welding wire, its copper-plated surface layer is easy to rust, the lubricant on the wire surface causes welding fume and spatter, and the copper-plated layer on the surface is easy to fall off. for CO 2 Gas shielded welding and CO 2 For the above-mentioned shortcomings of gas shielded welding solid copper-plated wire, a method of coating the wire with low spatter rate, good weld formation and low hazard surf...

Problems solved by technology

The experimental EDM surfacing equipment uses the principle of contact discharge to texturize the surface of the workpiece. The electrode is a tungsten electrode. Due to the high voltage, the textured surface obtained is generally too rough, so that the welding wire will produce continuous broken wires in the subsequent drawing process. , can not be produced normally, and will lead to less or uneven addition of surfactants, affecting the mechanical properties of metal deposition, and prone to major quality accidents
