Description

TECHNICAL FIELD

[0001] The utility model relates to extruder equipment technical field, concretely relates to a kind of extruder scraper multidirectional adjusting device. BACKGROUND

[0002] Extruder is the main equipment of light alloy (aluminum alloy, copper alloy and magnesium alloy) pipe, stick, section production, and it is processed into the section needed by pressure once.The working principle is to change the shape by applying pressure on material through slit or die.Extruder scraper is a key component in extruder equipment, and it is a device for removing excess material at the outlet of extruder head or distributing material evenly to die.It is usually composed of a scraper and a scraper, and its main function is to ensure that the material is evenly distributed during extrusion and to remove excess material after extrusion.

[0003] Generally, the installation and fixation of flat overflow scraper is to insert the scraper handle into the fixed concave sliding groove, and then fix them together with screws, which requires that the matching tolerance of the two should be controlled strictly.If the scraper is inclined, adjusting during extrusion will cause the distance between the outer edge of the extrusion wheel and the scraper blade to change unevenly, resulting in direct contact between the outer edge of the extrusion wheel and the scraper blade, which will be scratched and produce metal chips, causing serious decline in product quality, air bubbles and surface damage, etc.Once the defects caused by metal inclusions are found in production, the concave sliding block and the scraper should be replaced immediately, or the extrusion wheel should be repaired.From this point of view, the cost of manufacturing the scraper is correspondingly increased.This requires us to adjust the position of the scraper at the beginning, but the existing extruder scraper position adjusting device has defects, and can only adjust the front and rear distance.If the scraper is inclined, it is troublesome to adjust, and the scraper needs to be disassembled and reinstalled.
