Detection oil cylinder precompression balance and filling adjustment device of powder compacting equipment

Abstract

The invention relates to a detection oil cylinder precompression balance and filling adjustment device of powder compacting equipment. The detection oil cylinder is arranged in the powder compacting equipment. The device comprises a detection oil cylinder precompression balance device and a powder filling adjustment device, wherein an oil outlet pipeline of the detection oil cylinder precompression balance device is connected with an oil inlet pipeline of the detection oil cylinder, and the powder filling adjustment device is connected with the powder compacting equipment. By additionally arranging the detection oil cylinder precompression balance device in front of the detection oil cylinder, a balance valve of the precompression balance device is opened after every compression to compensate loss of oil pressure in the detection oil cylinder and the pipelines so that the oil pressure in a loop of the detection oil cylinder can recover to a set value, and accuracy of detection results of the detection oil cylinder is ensured. The powder compacting equipment is connected with the powder filling adjustment device so that accurate adjustment of powder filling amount is achieved. The detection oil cylinder precompression balance and filling adjustment device of the powder compacting equipment ensures quality of powder compression products, can control the powder filling amount by adjusting the precompression of the detection oil cylinder, is active in monitoring and flexible in operation, and improves work efficiency and rate of finished products.

Description

technical field [0001] The invention belongs to the technical field of parts or accessories of a press; auxiliary measures related to pressing, and particularly relates to a method of monitoring and detecting the oil pressure in the oil cylinder and responding to the pressing force, and controlling and detecting the pre-pressure of the oil cylinder to keep constant and accurately measure When pressing, the pressing force is finally completed through the connection between the mechanisms to complete the adjustment of the powder filling operation in the powder molding equipment. The oil cylinder pre-compression balance powder filling adjustment integrated device of the powder molding equipment. Background technique [0002] With the continuous improvement of automation in the powder forming industry, the requirements for precision are getting higher and higher, and the requirements for equipment are also getting higher and higher. Some equipment realizes full automation from pr...

Problems solved by technology

[0005] The technical problem solved by the present invention is that, since there is no proper way in the prior art to control and detect the filling time of the hydraulic oil in the oil cylinder, and after a series of powder pressing operations in the powder molding equipment, there will be loss of mechanical parts, Changes in oil pressure and powder consumption, etc., may cause the loss of hydraulic oil in the detection cylinder, which cannot accurately reflect the actual pressing force when testing powder products with the same volume, and the quality of the pressed product is not good. Off, weight deviation, low work efficiency, product qualification rate decline, and then provide a powder molding equipment with an optimized structure of the detection cylinder preload balance and filling adjustment device
