Abstract

The utility model discloses a kind of for processing the screw plate structure of windscreen wiper axis straight grain flower, it is characterised in that: screw plate main body thickness 5mm, screw plate body end centre fluting, 1 mm of groove width, deep 1 mm；The slot rounded corner.When the utility model is using thread rolling machining balance staff straight grain flower, slots among screw plate, finally take natural shape grooving in straight grain, simplify processing technology.The screw plate of the utility model has the stable service life, and simultaneous processing pit is able to satisfy technique requirement.

Description

A kind of screw plate structure spent for processing windscreen wiper axis straight grain

Technical field

The utility model belongs to the technical field of axis class process equipment thread rolling machine, and in particular to one kind is for processing windscreen wiper axis The screw plate structure of straight grain flower.

Background technique

Such as Fig. 1, in axis annular knurl position, for process without grooving process, annular knurl position is optical axis before annular knurl.Wiper axis at present Then the processing method of straight grain flower is machined by screw-rolling machine or thread rolling again usually in straight grain flower medium position grooving first Straight grain flower is formed, in straight grain flower machine-shaping, since grooving position gets out of the way screw plate, finally forms slot in the middle part of straight grain flower. Such as to process that molding axial workpiece (such as cold-heading part) to one slot of supplementary processing needs a list for shape Only process is completed, and processing efficiency is low, if slotless, axial pressure-off power is insufficient, influence using.

Summary of the invention

The purpose of this utility model is to provide a kind of for processing the screw plate structure of windscreen wiper axis straight grain flower, the screw plate Centre have a specific structure slot, the slot straight grain flower thread rolling molding when, screw plate groove location is got out of the way with axle body, thread rolling at Processing technology is simplified by open position self-assembling formation slot in slot when type.

It the purpose of this utility model and solves its technical problem underlying and adopts the following technical solutions to realize: Yi Zhongyong In the screw plate of processing windscreen wiper axis straight grain flower, it is characterised in that: including screw plate main body, screw plate main body is square, screw plate Main body thickness 5mm, screw plate main body have fluting, groove width 1mm, depth 1mm among the end of thread rolling line；The slot rounded corner.

When the utility model is using thread rolling machining balance staff straight grain flower, slot among screw plate, finally in straight grain flower Upper natural shape grooving, simplifies processing technology.The screw plate of the utility model has the stable service life, and simultaneous processing pit can expire Sufficient technique requirement.

Specific embodiment

Below in conjunction with attached drawing and preferred embodiment, to according to the utility model proposes one kind for processing windscreen wiper axis straight grain Colored screw plate structure specific embodiment, structure, feature and its effect, detailed description is as follows.

Referring to fig. 2-4, a kind of for processing the screw plate of windscreen wiper axis straight grain flower, it is characterised in that: including screw plate main body, Screw plate main body is square, screw plate main body thickness 5mm, and screw plate main body has fluting, groove width 1mm, depth among the end of thread rolling line 1mm；The slot rounded corner.

When the utility model is using thread rolling machining balance staff straight grain flower, slot among screw plate, finally in straight grain flower Upper natural shape grooving, simplifies processing technology.The screw plate of the utility model has the stable service life, and simultaneous processing pit can expire Sufficient technique requirement.Referring to Fig. 5, screw plate processes balance staff schematic illustration；Referring to Fig. 6, balance staff after processing is completed is illustrated Figure.

The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model Limitation, it is any without departing from the content of the technical scheme of the utility model, according to the technical essence of the utility model to above embodiments Made any simple modification, equivalent change and modification, are still within the scope of the technical solutions of the present invention.
