Embodiment Construction

[0021] An impregnation process, which includes three stages of impregnation pretreatment, impregnation treatment, and impregnation post-treatment.

[0022] The impregnation pretreatment is as follows: manually put the workpiece into the impregnation basket, hang the impregnation basket into the degreasing tank with a gourd crane, close and lock the cover of the degreasing tank, bubbling for 15 minutes, open the cover, take out the impregnation basket and remove it. Put it into the cleaning tank, wash it with cold water for 2 minutes, up and down 5 times, take out the impregnation basket and move it to the centrifuge tank, close the tank, dry it centrifugally (forward rotation, reverse rotation, stop), open the cover, take out the impregnation basket and move it to the Dry in an oven at 110°C for 10 minutes, then move to a drying rack to dry.

[0023] The impregnation treatment is as follows: put the impregnation basket containing the workpiece into the impregnation tank withou...

Abstract

The invention relates to an infiltration technique and device. The technique comprises three phases, namely infiltration preprocessing, infiltration processing and infiltration postprocessing. The infiltration device comprises an infiltration basket, a hoist hook, a degreasing pot, a cleaning pot, a centrifugal pot, a baking oven, an infiltration pot, a vacuum pump, a glue storing pot, an air compressor, a washing pot, a solidifying pot and a pressure test device, wherein all the components are arranged in a straight line. Due to the fact that the infiltration pot is cylindrical, influence of sewage on a production site can be effectively avoided. Due to the fact that the infiltration pot is locked with a method that a sealing lock ring is inflated by a lock ring cylinder and both a toothed ring of a pot cover and the lock ring are manufactured with whole materials, sealing performance is good, operation is safe and fast, the pot cover can be opened and closed automatically and fast, no relative motion exists between the pot cover and a sealing ring, friction does not exist, opening is flexible, and the service life is long. The infiltration technique and device have the advantages that the device is compact and reasonable in structure, the whole production site is beautiful, logistics is smooth, and fixed location management and civilization and cleanliness of the production site can be ensured.

Description

technical field [0001] The invention relates to the technical field of impregnation, in particular to an impregnation process and a device thereof. Background technique [0002] In the manufacturing process of die castings and powder metallurgy parts, due to gas residues, crystal shrinkage and other reasons, a large number of micropores, blisters, and cracks are inevitably formed, and the leakage of micropores has brought great hidden dangers to the use of machinery and equipment, namely It may also be used in applications without pressure requirements due to the plating solution, acid solution, etc. entering the interior of the parts during electroplating, painting and other surface treatments, resulting in internal corrosion and shortening the service life of the parts. Bubbles or bumps. [0003] The impregnation process is a microporous or slit infiltration sealing process, that is, the sealing medium (usually a low-viscosity liquid) is infiltrated into the micropores or...
