Embodiment Construction
[0041] The present invention will be further described below in conjunction with accompanying drawing:
[0042] With reference to accompanying drawing, the present invention a kind of powder metering and filling method of wet bag soft film of cold isostatic pressing machine, it comprises shock filling unit, metering discharge unit and feeding unit composition, the powder in transfer bin 15 The material 10 is metered and filled into the soft film 2, which is divided into the following two stages: first, the metering process of the preset filling weight G is completed in the first stage, and the filling weight G is pre-inputted by the keyboard and stored in the electric control box 17 as required In the ROM of the control unit, before the start of measurement, the feed valve 12 of the transfer bin 15 is opened. During the measurement, the powder material 10 is fed into the scale hopper 8 from the transfer bin 15 through the transition hopper 11, and the feeding device 9 is contro...

Abstract
The invention relates to a powder metering filling method for a soft film of a wet bag of a cold isostatic press and a powder metering filling device for the soft film. The powder metering filling device comprises a jolting filling unit, a metering discharging unit and a feeding unit. Powder materials in a transfer silo are filled into the soft film in a metered manner, and the filling method and the filling device avoid loss and secondary pollution of the materials, less pollute surroundings, easily realize automation and are excellent in operability. The density of the filled powder inside the soft film is approximately uniform, and the filled powder can directly enter the cold isostatic press along with a steel sheath without manual beating and rubbing, so that the qualification rate of pressed finished products can be met after the filled powder is pressed by the cold isostatic press. Actual operation indicates that after the filled soft film is pressed and sintered by the cold isostatic press in a later period, the average density of the filled soft film is 6.39g / cm3, the outer diameter of the filled soft film is 97mm, the average deviation of the filled soft film is + / -2mm, and use requirements of the soft film are completely met.
Description
1. Technical field [0001] The invention relates to a powder metering and filling method for wet bag soft film of a cold isostatic press. The powder metering filling method is used for metering and filling of powder materials in the wet bag soft film in the early stage of cold isostatic pressing. 2. Background technology [0002] As a kind of isostatic pressing technology, wet bag isostatic pressing technology can change the shape and size of the soft film arbitrarily, and the product is very flexible. It is widely used in the fields of metallurgy, ceramics, casting, atomic energy, plastics, and graphite. . For the filling of the soft film in the early stage of isostatic pressing, since the loose volume of the powder material to be filled is greater than the effective volume of the hose, natural filling is difficult to achieve. The current filling process is still based on manual filling. First, the weighed powder Load the soft film in several times to make it firm, then use...
