Hydraulically driven mechanical powder molding machine

Abstract

The invention relates to a hydraulically driven mechanical power molding machine. The hydraulically driven mechanical power molding machine comprises a machine body, an upper limiting oil cylinder, alead screw adjusting structure, a lower oil cylinder structure, a feed mechanism and a formwork assembly. The machine body is a frame machine body. The upper limiting oil cylinder, the lead screw adjusting structure, the formwork assembly and the lower oil cylinder structure are sequentially arranged on the middle of the machine body from top to bottom. The feed mechanism is arranged on one side of the machine body. The upper limiting oil cylinder is connected to the lead screw adjusting structure. The lower end of the lead screw adjusting structure is connected to the formwork assembly. The lower end of the formwork assembly is connected to the lower oil cylinder structure. The hydraulically driven mechanical power molding machine has the characteristics of simple structure, reliable operation, high automation, and convenient mould installation. The hydraulically driven mechanical power molding machine further has advantages of high efficiency, high powder loading, stable product compression and the like. Quickly pressing powder metallurgy parts at a lower cost in the powder metallurgy industry of China becomes possible.

Description

Technical field [0001] The invention relates to the field of powder molding machines, in particular to a hydraulically driven mechanical powder molding machine. Background technique [0002] At present, there are basically two types of powder molding machines, one is a mechanical powder molding machine, and the other is a hydraulic molding machine, which is driven by a crankshaft and a cylinder respectively. The actions are multi-axis linkage and series single cycle. The mechanical press has the advantages of high efficiency and stable size of the batch pressed products. But at the same time, there are the shortcomings of short continuous pressing time and low powder filling height, which are difficult to overcome; the forming efficiency of hydraulic press is low, and the pressed product is limited by the oil temperature and hydraulic principle, and the product size fluctuates greatly. However, the height of the powder filling of the hydraulic press is not limited, the pressure...

Problems solved by technology

But at the same time, there are shortcomings of short continuous pressing time and low powder filling height, which are difficult to overcome; the forming efficiency of hydraulic press is low, and the pressed products are limited by oil temperature and hydraulic principle, and the product size fluctuates greatly.

However, the powder filling height of the hydraulic press is not limited, the pressure holding time is long, the product is fully exhausted, and the sintering is not easy to expand and crack.

For presses with the same pressing tonnage, mechanical forming machines are expensive due to their complex mechanism, and are generally several times the price of hydraulic forming machines.
