Spraying system for axle forging and pressing dies of electric vehicles

Abstract

The invention discloses a spraying system for axle forging and pressing dies of electric vehicles, and relates to the technical field of vehicle axle spraying. The tops of multiple sets of support columns are fixedly connected through a transverse plate, sliding grooves are formed in the front and rear end faces of the transverse plate, the left side of the transverse plate is provided with a mounting plate, and the front and rear end faces of the mounting plate are provided with hydraulic devices; matched sliding blocks are installed in inner cavities of the sliding grooves, the top of each sliding block is provided with two mounting rods, two spraying adjustment blocks are arranged on the mounting rod at the left side of the top of each sliding block, and two purging adjustment blocks are arranged on the mounting rod at the right side of the top of each sliding block; the bottom of the mounting plate is provided with a blower, and an inner cavity of a material spraying bottle is provided with a hydraulic pump; through the cooperation of adjustment grooves, adjustment holes and positioning bolts, the distance of the spraying adjustment blocks can be conveniently adjusted, the requirement of spraying the axle forging and pressing dies of different types is met, another device is not needed for replacement, the time is saved, the working efficiency is greatly improved, and meanwhile the spraying cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile axle spraying, in particular to an electric automobile axle forging die spraying system. Background technique [0002] The role of the release agent is to form a protective film between the mold and the hot forging blank, to avoid direct contact between the hot metal and the mold during the forging process, thereby avoiding the melting and bonding of the forging metal and the mold, resulting in duplication of the mold Utilization rates are reduced, which increases production costs. [0003] In the selection of the release agent, due to the layered structure of flake graphite itself, graphite has a relatively high ignition point (above 700 ° C), and its thermal conductivity is very good. In addition, graphite itself is incompressible. A graphite layer with a suitable particle size can isolate the hot metal from the mold, and the heat can be transmitted laterally without adhesion, so that the mo...

Problems solved by technology

[0004] At present, the automobile axle forging die is long. If a fixed nozzle is used for spraying, not only the surface coverage is poor, the thickness of the covering layer is uneven, but also the spraying amount is very difficult to control. According to the Chinese patent application number: CN201621203648.X proposed A spraying system for automobile axle forging molds, including a release agent storage tank, a high-pressure release agent delivery unit and a mobile atomization spray unit, the release agent storage tank is connected to the mobile atomization spray unit through the release agent high-pressure delivery unit, although it can To solve the above problems, but it is still impossible to adjust the spacing according to different models of automobile axle forging dies, and another equipment needs to be replaced for spraying work, which not only increases the cost of spraying, but also wastes time when replacing equipment, which greatly reduces Work efficiency, for this reason, we propose a spraying system for electric vehicle axle forging dies
