Automatic ink-jet blowing system for hot die forging press

Abstract

The invention discloses an automatic ink-jet blowing system for a hot die forging press. The automatic ink-jet blowing system comprises an ink-jet system and a blowing system, which are arranged on an upper die seat of the hot die forging press, wherein the ink-jet system is used for jetting ink to cavities of dies on upper and lower die seats of the hot die forging press; and the blowing system is used for blowing air to the cavity of the die on the lower die seat of the hot die forging press. The automatic ink-jet blowing system is simple in structure, reduces the labor intensity of workers, can shorten production takt and improve the production efficiency; and particularly, the system is good in blowing cleaning effect, uniform and disperse in spraying, high in spraying speed and stable and reliable in operation.

Description

technical field [0001] The invention relates to a hot die forging press, in particular to an automatic inkjet blowing system for a hot die forging press. [0002] Background technique [0003] Hot die forging press is an indispensable high-precision forging equipment for modern forging production. It is used for die forging and finishing forgings of metals. The forgings produced have high precision, high material utilization, high productivity, and are easy to realize automation. Existing hot die forging presses are mainly composed of upper and lower die bases and molds installed on the upper and lower die bases. The upper and lower die bases are connected by guide columns, and the upper die base moves up and down along the guide columns to realize forging and opening. Die; Usually, the guide column is located between the die and the rear side of the upper and lower die holders, so that the operator can move and take out the forgings. But existing hot die forging press sti...

Problems solved by technology

[0004] 1. During the forging process, there will be friction between the forging and the mold, and the friction will change the internal stress state of the crankshaft blank, increase the deformation resistance and thus increase the energy consumption; it will also cause uneven deformation, resulting in additional stress and residual stress Reduce the plasticity of the forging or even cause damage, or change the size and shape of the finished product, shortening the product life; at the same time, the friction will directly wear the contact surface of the mold, and the heat generated will soften the mold material, and the friction will also reduce the life of the mold and cause equipment damage. ;

[0005] 2. In the pre-forging process, with the deformation of the material, the oxide shell with almost no plasticity on the surface is broken into oxide scale fragments; some of this layer of oxide scale adheres to the surface of the forging blank, which will affect the next process—— The forming quality of the final forging will bring unnecessary troubles to the next process, and will also affect the final surface accuracy of the forging and the service life of the die; some will adhere to the surface of the die cavity, occupy the filling position of the metal material, and affect the next billet The forming size of the forgings will affect the forming accuracy of the forgings, which will eventually lead to a decrease in material utilization.

[0006] In order to reduce the friction between the forging and the mold, graphite is mainly coated in the mold. The current graphite coating is mainly sprayed manually by the staff, but manual spraying is not only time-consuming, but also the amount of ink sprayed is uneven. , it often causes the lubrication effect is not good enough, specifically manifested as the difficulty in taking the mold of the forging or even the phenomenon of sticking the mold; when the sticking occurs, the forging must be stopped, and the forging can be taken out of the forging with a tool prying piece, which is very difficult for the operator. Increased labor intensity also affects the surface quality of forgings; not only tools are easily damaged, but also often cause forgings to be scrapped
