Abstract

The invention provides a production technology of precision-type high-pressure and high-density pipe fittings. Through improvement of cooling devices, shearing devices, heating devices of extruders and temperature control systems, labor intensity is greatly reduced, product quality is improved and production cost is reduced.

Description

A kind of accurate high pressure high density pipe part production technology
Technical field
The present invention relates to a kind of accurate high pressure high density pipe part production technology.
Background technology
Existing P E pipe part production technology, because it designs not science producing streamline, cause following deficiency: the one, because extruder heater science not causes power consumption big, and environment is polluted; The 2nd, because the not science of cooling device causes the waste of water resource; The 3rd, because the not science of shear causes labour intensity big; The 4th, because the not science of temperature control system causes the increase of percent defective.
Summary of the invention
Purpose of the present invention is exactly at deficiency of the prior art, provides a kind of on the basis of existing tube extruding equipment and technology, and extruder mould and expressing technique are carried out improved pipe part production technology.
Technical scheme of the present invention is from the following aspects equipment to be improved on the basis of existing PE tubing extruding production line:
1, the improvement of cooling device: the forced circulation type of cooling that original straight-line type of cooling that adopts is improved to immersion type.The improvement of this mode is the conserve water resource greatly.
2, the improvement of shear: be improved to full-automatic fixed-length by existing artificial shearing and shear, not only enhance productivity, reduce labour intensity, and improve and cut out quality.
3, the improvement of the heater of extruder: " UFour is excellent to be inspired confidence in, and " electromagnetism mode of heating, electromagnetism add hot rolling and are installed in the water back outside, and pipeline is subjected to the electromagnetic induction body self-heating cooking in employing.Easy for installation, have linear, circle and two kinds of frame modes of discoid, and between pipeline and coil, add thermal insulation layer, further improve the thermal efficiency and heat insulation effect.Power density is big: the alternative former 2-3 electric heating coil of single electromagnetism heating collar.Important technological parameters: operating voltage 220V; AC power 1.2-12KW; Electromagnetic coil width 80-300mm, the electric former 5-10 that works is adjustable, electromagnetic coil diameter 〉=80mm, mean free error time 〉=10000 hour.The improvement of this device is compared with the heating of the electric heating coil of existing employing, and economize on electricity can reach 40%-80%.
4, the improvement of temperature control system: adopting the PLC control system is main the selection.Both functions are respectively: blind controller system can be realized switch two controls in the temperature control, also can adopt intelligence instrument to realize simple rate control, and the PLC control system can realize PID(ratio-integration-differential control by analog quantity communication) control; The former shows melt pressure at pressure control, and the latter shows melt pressure and realize closed-loop control, and the former test function has only Presentation Function, then can realize the serial communication of test cell.The improvement of native system can reduce the temperature fluctuation of heating cooling procedure greatly, reduces the waster output.
The present invention has greatly reduced labour intensity by the improvement to existing production technology, has improved the quality of product, and has reduced production cost.
