The invention discloses a lamination-vacuum pressure pouring technology of a microminiature conducting slip ring, which comprises the processing technology of a conducting ring, the processing technology of a brush holder and the general assembly technology of the microminiature conducting slip ring; after the conducting ring body and the brush component are inspected, the bought-in component inspection is carried out on the bought-in components such as a combination support, a flange, a dust shield, and the like; and then the conducting ring body, the brush holder component and the bought-incomponents are assembled into the microminiature conducting slip ring, and then tested and inspected; and after passing the inspections, the conducting ring body, the brush holder component and the bought-in components are packed and delivered. The lamination-vacuum pressure pouring technology of the microminiature conducting slip ring is characterized in that: after the conducting ring is manufactured and an insulating strip is processed, the conducting ring and the insulating strip are firstly laminated for assembly, epoxy resin is poured at the vacuum pressure, and then fine machining is performed on the conducting ring body. The lamination-vacuum pressure pouring technology of the microminiature conducting slip ring has the advantages that the two conducting rings are both mutually insulated and reliably connected, and rubber layers thereof can not fall off, the environmental suitability and operational reliability of the products are improved, the rate of defective products is low, and the performance of the product can correspond to that of the similar products abroad.

The invention relates to a device for holding objects, preferably a telephone, in particular for use in a center arm rest and / or the center console of a vehicle, with a frame or receptacle and a reversibly closable lid which is mounted so that it may be swiveled in each case about one of the rotary axes arranged in the region of the upper closing edges of the side walls of the frame or container and lying essentially parallel to the closing edges. The lid has an opening and closing mechanism which is arranged in a function carrier frame that may be connected to the lid. In addition, the invention relates to a method for the production of a device for holding objects, in particular for use in a center arm rest and / or the center console of a vehicle.

The invention relates to an air-cushion floating non-contact wax coating mechanism which is characterized in that a wax coating spindle penetrates through axial center holes of a first expansion sleeve and a second expansion sleeve sequentially; an air distribution hub is arranged on the profile surface of the first expansion sleeve in an embedding manner; a star wheel hub is arranged on the profile surface of the second expansion sleeve in an embedding manner; a wax coating star wheel is fixedly connected with the star wheel hub; air guide holes are formed in the edge of the wax coating starwheel; a closed space is formed among the air distribution hub, a star wheel hub and a wax coating star wheel; vacuum spacing blocks and compressed air spacing blocks are arranged inside the closed space; the closed space is divided by the vacuum spacing blocks and the compressed air spacing blocks into vacuum adsorption areas and compressed air action areas; and the vacuum adsorption areas or thecompressed air action areas in the closed space communicate through the air guide holes. According to the technical scheme, pop-top cans are prevented from being in contact with a metallic wax coating star wheel body when coated with wax, the rejection rate during the production can be reduced, the structure can be simplified, the maintenance cost can be reduced, the downtime can be shortened, and the production efficiency can be improved.

The invention relates to a centrifugal casting method of a magnesium alloy hub, which belongs to the technical field of casting. The prior gravity and low-pressure casting method for casting the magnesium alloy hub exists the easily occurred casting defects of incompleteness of mould filling, shrinkage cavity, cold shut, hot cracking, shrinkage cracking, and the like. An upper die, a side die anda lower die of a die are matched and then held into a whole, then gravity center casting is carried out for the matched die, the die is enabled to rotate around the axes thereof for a set time and then stop before cast magnesium melt solidifies, the cast mode can be divided into casting before die rotating and casting after die rotating according to the technological requirements of concrete products, and the die is opened to take out a cast after the magnesium alloy melt solidifies. With the method, the magnesium melt in the die can rapidly fill shrinkage towards peripheral parts under the action of centrifugal force to enable cast products to be full and compact, and the method has the advantages of low production rejection rate, compact structure of casts, improvement of quality of workpieces, and the like.

The invention discloses an automatic pipe outer diameter control system. The automatic pipe outer diameter control system comprises a negative pressure detection gauge, a temperature detection device, a single-chip microcomputer, a touch screen, a vacuum pump, a negative pressure pipeline, a pipe sizing sleeve device and an alarm device. The vacuum pump is connected with the pipe sizing sleeve device through the negative pressure pipeline, the negative pressure detection gauge is installed on the negative pressure pipeline, the touch screen is installed on the single-chip microcomputer in a connected mode, and the single-chip microcomputer is connected with the negative pressure detection gauge, the temperature detection device, the vacuum pump and the alarm device. The pipe sizing sleeve device comprises a sizing sleeve shell, a pipe sizing sleeve, a spray cooling mechanism and a sealing mechanism. By additionally arranging the negative pressure detection gauge and other devices, the pipe outer diameter sizing process is automatically regulated and controlled, manual work is reduced, and the rejection rate of production is reduced; meanwhile, an alarm can be given to remind operators to carry out emergency processing when changes beyond the automatic regulation and control capability of the system happen, and thus the safety coefficient of production is increased; by arranging a frequency converter, the vacuum degree of the vacuum pump can be regulated, and meanwhile electric energy can be saved.
