Embodiment Construction

[0012] Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing

[0013] Concrete practice mud step of the present invention is as follows:

[0014] 1. Install 1-2 disc plane bearings 3 in the center hole of the spiral blade 1 at the end of the three-blade mud training machine and the tapered end of the tapered mud training bowl 2, and the specification model is 51304 or 51306.

[0015] 2. Change the connection between the conical mud training machine bowl 2 and the screw blade 1 at the end of the three-blade mud training machine from a solid iron connecting rod to a high-strength drag chain 4, and its specification is an 80-grade lifting chain 6x8 or 7x21.

[0016] 3. Adjust the length of the flat extension part of the conical clay training bowl 2 to 300-400mm.

[0017] 4. Weld one end of the high-strength drag chain 4 to a Ф25-30mm, 50-80mm long circular member with screws to connect with the spiral leaf 1 at the...

Abstract

The invention relates to an insulator vacuum pugging method and an insulator vacuum pugging device. A center hole of a three-blade tail end spiral blade of a pugging machine and a tapered end of a tapered pugging bowl body are respectively provided with 1-2 plane bearing(s), and the tapered pugging bowl body is connected with the three-blade tail end spiral blade of the pugging machine by a high-intensity pull chain. After the insulator vacuum pugging method and the insulator vacuum pugging device are used, the tapered pugging bowl body is always under the suspension status at an outlet of the pugging machine through the pull chain, when the pugging machine is started up to run, the pug can uninterruptedly and evenly move to a tapered pugging machine bowl body from the periphery. Therefore, the tapered pugging machine bowl body can be always arranged in the middle of the outlet of the pugging machine, a hollow pug section inner hole which is extruded under vacuum can never be eccentric, and ripples can not be available. The pug section pug extruded by the method is even in density, and compact in molecular structure, a formed semi-product is difficult to bend, and a sintered product can not be deformed.

Description

technical field [0001] The invention relates to a method and a device for vacuum clay refining of a porcelain sleeve. Background technique [0002] With the rapid development of the power industry, the demand for transformers, circuit breakers, surge arresters, transformers, and surge arresters for high-voltage and ultra-high-voltage electrical equipment has increased rapidly. Most of these porcelain sleeves for high-voltage and ultra-high-voltage electrical equipment are hollow and straight, and both ends are made of aluminum alloy glue injection flanges for connection. [0003] Production and processing of this kind of high-pressure, ultra-high-voltage straight-tube hollow electric porcelain bushing. The usual mud section extrusion method is to design the clay pot according to the inner diameter of the porcelain bushing, and connect the mud pot to the screw at the end of the vacuum mud mill with a solid connecting rod. leaf. When the mud is added into the mixing port of ...
