Adhesive pressure forming equipment

Abstract

The present invention relates to a viscosity pressure forming technique for working plate material and its equipment. Said equipment adopts a divided hydraulic cylinder to implement forming and pressing operation, the viscosity medium and pressure oil are isolated by means of piston in the control cylinder. Its hydraulic system is divided into high-pressure system and low-pressure system, in which high-pressure system is used for implementing forming operation, and its low-pressure system is used for implement flanging operation and stroke-returning operation of all cylinders. Said invention can utilize programmable controller to implement control of hydraulic system, its structure is novel and its operation is convenient.

Description

(1) Technical field: [0001] The invention proposes a device for plate processing using viscous pressure forming technology. (two) background technology: [0002] Before viscous pressure forming, sheet metal half-mold forming technology was widely used. Sheet metal half mold forming, also known as sheet metal soft mold forming. Liquid-filled forming is a relatively mature technology in soft mold forming. It was put into industrial application from the late 1970s to the early 1980s. Some industrially developed countries such as Japan and the United States have launched special equipment for liquid-filled deep drawing of various specifications. , but the operation of liquid filling forming is complicated and the oil pressure is difficult to control due to problems such as leakage. When the forming fails, the oil splashes, pollutes the environment, and endangers the operator; in addition, the oil adhered to the surface of the parts makes the operation inconvenient or needs to b...

Problems solved by technology

However, the modified equipment has poor reliability, low precision, inconvenient operation, and it is difficult to meet the requirements of viscous pressure forming.

At present, with regard to viscous pressure forming, it is mainly based on the general-purpose press, which is partially modified, but the modified equipment has poor reliability, low precision, inconvenient operation, and it is difficult to meet the requirements of viscous pressure forming. The reason is mainly due to the viscous pressure forming. The main feature is to achieve the purpose of forming non-isostatic pressure by controlling the discharge position and discharge pressure of the medium in the die. It is difficult to effectively control it when retrofitted on general-purpose equipment, so the advantages of viscous pressure forming cannot be fully utilized.
