Description

A kind of processing method of the plate parts with opening elongated slot

Technical field

The present invention relates to die cutting equipment, also relate to Machining Technology, relate in particular to the processing method of a kind of cycle type die-cutting machine with the plate parts with opening elongated slot.

Background technology

Die cutting product is widely used in automobile making, electron trade.Especially plane shows industry, does not use nowhere especially stratiform thin material, and insulating materials, packing, heat-resisting heat-barrier material, sticker product, dust-proof material, shielding material etc. all need to adopt die cutting technique processing and manufacturing.

With operation principle, distinguish, die-cutting machine is divided into cycle type die-cutting machine and flat-crushing type die-cutting machine.Wherein cycle type die-cutting machine is high with its precision, and fireballing feature has advantage very in production in enormous quantities.

The work of die-cutting machine and precision, depend mainly on the depth of parallelism of paired rotor, and the depth of parallelism of rotor directly depends on the precision of a pair of tool rest side plate for rotor is installed, the flatness General Requirements of tool rest side plate is below 0.015mm, and the height of tool rest side plate is generally wanted 400mm to 600mm, adding cutter shaft installation slotted hole is the hole with opening, easily distortion, and its difficulty of processing is very large.Be often while detecting on process equipment, the perpendicularity of the flatness of tool rest side plate and slotted hole and side plate datum level meets the requirements, and when workpiece is after process equipment unloads, morpheme work is poor changes, and it is also like this adopting modified material.

The processing with opening elongated slot part similar to aforementioned applications, requirement, especially the elongated slot bottom size that is always difficult to reach higher hour, is out of shape seriously especially, but the size of elongated slot bottom size determined by mechanical structure, can not arbitrarily change.

Summary of the invention

The processing method that the object of the invention is to overcome above-mentioned the deficiencies in the prior art part and provide a kind of plate parts with opening elongated slot that can guarantee element precision.

The processing method that the present invention also aims to overcome above-mentioned the deficiencies in the prior art part and provide the plate parts with opening elongated slot that a kind of non-deformability is strong.

Object of the present invention can be achieved through the following technical solutions:

A processing method for plate parts with opening elongated slot, is characterized in that comprising the following steps: S10), rough mill; S20), modified; S30), corase grind, half finish-milling; S40), high-temperature aging; S50), half fine grinding; S60), cold treatment; S70), finish-milling, fine grinding; Wherein, the described plate parts with opening elongated slot comprises front, reverse side, edge and opening elongated slot, and the material of this part is steel; Rough milling S10) refers to rough mills opening elongated slot and edge; S30) described corase grind refers to that corase grind is positive, reverse side, and described half finish-milling refers to half; S40) temperature of described high-temperature aging is controlled at 500-550oC, and temperature retention time is controlled at 5-7H, with 30-50oC/H with the cold insulation of stove after stove to be chilled to the nature of coming out of the stove after 200-300oC cooling; S50) described half fine grinding refers to half fine grinding positive and negative; S60) described cold treatment refers to and part is continued to be cooled in 0 degree medium subzero 75-85 oC, until be cooled to after temperature uniformity, takes out; S70) described finish-milling, fine grinding refer to by the extremely final requirement of part finish-milling opening elongated slot and edge, by extremely final positive and negative fine grinding requirement.

The processing method of the plate parts with opening elongated slot, is characterized in that: the material of described part is quenched and tempered steel, or the material of described part is 40Cr.

The processing method of the plate parts with opening elongated slot, is characterized in that: S40) temperature of described high-temperature aging is controlled at 500-550oC, temperature retention time control is 6H, with 30-50oC/H with the cold insulation of stove after stove to be chilled to the nature of coming out of the stove after 200-300oC cooling.

The processing method of the plate parts with opening elongated slot, is characterized in that: S60) described cold treatment refers to and part continued to be cooled in 0 degreemedium subzero 80 oC, until be cooled to after temperature uniformity, takes out air cooling;

The processing method of the plate parts with opening elongated slot, is characterized in that: when this plate parts is used in pairs or in groups, and S70) described finish-milling operation is processed in pairs or in groups in the lump, and marking is distinguished with other part.

The processing method of the plate parts with opening elongated slot, is characterized in that: the method is for processing the forward and backward knife-die seat side plate of cycle type die-cutting machine.

The processing method of the plate parts with opening elongated slot of the present invention, rough mill modifier treatment after elongated opening, eliminate material stress, high-temperature aging after corase grind, half finish-milling, allows semi-finished product be out of shape very fully, then half fine grinding, cold treatment again, the sizing of card part, anti-upper part unloads redeformation in rear or use afterwards, increases the ability of its resistance to deformation; After finish-milling, fine grinding arrive drawing chi, morpheme station no longer changes.Compared with prior art, by high-temperature aging, allowed part fully be out of shape on the one hand, rare internal stress, on the other hand by cold treatment, allow part sizing and increase the ability of its anti-redeformation, so adopt the present invention's the element precision of method processing high, non-deformability is strong.
