Intelligent metal plate molding machine

Abstract

The invention discloses an intelligent metal plate molding machine. The intelligent metal plate molding machine comprises a base, an upper mold plate, a lower mold plate, an ejection oil cylinder, stand columns, an edge pressing module, a molding oil cylinder and edge pressing oil cylinders, wherein the lower mold plate is fixedly mounted on the base, the piston rod of every edge pressing oil cylinder penetrates the upper mold plate and is connected with the upper mold plate, and the molding oil cylinder, the edge pressing oil cylinders and the ejection oil cylinder are all connected with a pump control hydraulic system. The pump control hydraulic system comprises a plurality of hydraulic control check valves and a first electro-hydraulic directional control valve, wherein the plurality of hydraulic control check valves are used for respectively locking the oil supply pipelines of the plurality of edge pressing oil cylinders during the edge pressing process, and the first electro-hydraulic directional control valve is connected with the hydraulic control check valves. The pump control hydraulic system is connected with an automatic control system which is used for adjusting the output pressure of the pump control hydraulic system. The intelligent metal plate molding machine can automatically adjust the pressure of the pump control hydraulic system according to the drawing force needed during the workpiece drawing process, can guarantee the product quality, is low in power loss and good in energy-saving performance, can automatically achieve feeding and blanking and has a high production efficiency, low production costs and a low accident occurrence rate.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a sheet metal forming machine. Background technique [0002] At present, there are many products of hydraulic forming machines on the market, but the hydraulic forming machines in the prior art have the following disadvantages: the degree of automation is relatively low, that is, many actions of the equipment are manually operated during the production process of the product, especially the production of the product. Loading and blanking are generally manual operations, which are inefficient and pose a certain risk to personal safety; without intelligence, that is, in the process of product production, the material, shape, and size of the product cannot be identified, especially when the product is replaced, the adjustment of the template It is time-consuming and labor-intensive, and requires experienced technicians to adjust; it is not energy-saving.

[0002] At present, there are many products of hydraulic forming machines on the market, but the hydraulic forming machines in the prior art have the following disadvantages: the degree of automation is relatively low, that is, many actions of the equipment are manually operated during the production process of the product, especially the production of the product. Loading and blanking are generally manual operations, which are inefficient and pose a certain risk to personal safety; without intelligence, that is, in the process of product production, the material, shape, and size of the product cannot be identified, especially when the product is replaced, the adjustment of the template It is time-consuming and labor-intensive, and requires experienced technicians to adjust; it is not energy-saving. The power source of the existing hydraulic system adopts a valve control system composed of an ordinary motor and a quantitative pump, and the output power in the design is often greater than the power required by the product. Part of the power can only be lost through the hydraulic valve, which wastes energy and is not environmentally friendly; during the blank-holding process, the blank-holding force is insufficient, causing wrinkles on the workpiece, or the blank-holding force is too large, causing damage to the workpiece, wasting man-hours and raw materials, and increasing production costs
