Device for machining ultra-large lead inner helixes of machine barrel of plastic extruder

Abstract

The invention discloses a device for machining ultra-large lead inner helixes of a machine barrel of a plastic extruder. The device comprises a bottom plate (7), a supporting base (8) which is arranged on the bottom plate (7), and a power device (10), and is characterized in that: a supporting rod (6) is arranged in the supporting base (8); a belt wheel (11) is arranged at one end of the supporting rod (6); on the one hand, the belt wheel is connected with an output shaft of the power device (10) through a first driving belt (12), and on the other hand, the belt wheel is connected with a power wheel on a micro milling head (4) through a second driving belt (9); skewed slots are symmetrically formed at one end of the supporting rod (6), which is extended into a machine barrel (5); an oblique angle-shaped supporting block (3) is arranged in each skewed slot; the big end of each oblique angle-shaped supporting block (3) is pressed against the inner wall of the machine barrel (5), and thesmall end of each oblique angle-shaped supporting block (3) is pressed against an adjusting screw (1) which is arranged on an adjusting support (2); and the adjusting support (2) is arranged on the end face of one end of the supporting rod (6), which is extended into the machine barrel (5). The device for processing the ultra-large inner helixes of the machine barrel of the plastic extruder is simple in structure, is convenient to manufacture and is high in machining efficiency.

Description

technical field [0001] The invention relates to a mechanical processing device, in particular to a plastic extruder barrel processing device, in particular to a plastic extruder barrel super-lead internal helix processing device. Background technique [0002] At present, with the continuous research on the forming mechanism of plastic machines, people have found that better plasticizing effects can be obtained by changing the shape of the screw and barrel, which is conducive to improving the internal quality and appearance quality of injection molding products. Therefore, in In the plastic machine market, the inner wall of the machine barrel has developed from the traditional single light cylindrical structure to various special-shaped inner walls. Various new machine barrel products are developing in a diversified and specialized development trend, and conventional products have gradually lost their competitiveness. People have found through research that processing the...
