Abstract
The invention discloses a round hole plunger chip processing technology. Cr12MoV steel is selected as a raw material, spheroidizing annealing, mechanical roughening, quenching and tempering are conducted, and then a CO2 laser of 5 KW is used for conducting laser surface quenching on round hole plunger chips. The CO2 laser of 5 KW can quickly scan the plunger chips by high energy laser beams, a layer of ultra-thin shell on the surface of each plunger chip can quickly absorb energy so that the temperature can sharply rise, self-quench hardening can be conducted instantly, surface hardening of the plunger chips is achieved, the insides of the round hole plunger chips still keep the high toughness, and the service life of the round hole plunger chips is prolonged.
Description
Technical field
The present invention relates to Machining Technology field, a kind of circular hole drift processing technique.
Background technology
Drift is the part in diel, is arranged in diel and carries out continuous stamping punching press and thrust operation, makes machined material occur to separate or plastic deformation, thus the finished product required for obtaining or semi-finished product.Drift is arranged in diel, directly contacts with material during work, makes material deform upon, cuts material.Circular hole drift is used to stamp out the drift of circular port.
The selection of circular hole drift is the most traditional at present, and its processing technique is the most relatively conventional, usually only with the heat treatment method processing drift of quenching and tempering.This type of processing technique is excessively simple, and the circular hole drift firmness outside manufactured is big, but the toughness in heart portion is inadequate, and the service life causing drift is the shortest.
Summary of the invention
It is an object of the invention to for above-mentioned deficiency of the prior art, it is provided that a kind of circular hole drift processing technique.
It is an object of the invention to be achieved through the following technical solutions:
A kind of circular hole drift processing technique, using cylindrical Cr12MoV steel alloy is machining blanks material, carries out the processing of following steps:
(1) spheroidizing: drift blank material is heated to 700～720 DEG C of insulation 2h, then air is cooled to 650～670 DEG C of insulation 6h, last air is cooled to room temperature；
(2) machinery roughing: use numerically controlled lathe that the blank material after spheroidizing is carried out turnery processing, process circular hole drift blank, and leave allowance；
(3) quenching: being put into by the circular hole drift blank obtained through step (2) and be heated to 860～890 DEG C of insulation 3h in glowing furnace, oil is cooled to room temperature；
(4) tempering: being put into by the circular hole drift blank after quenching and add in tempering furnace to 320～360 DEG C, air cooling is to room temperature, then circular hole drift blank polish is shaped with numerically controlled lathe, obtains circular hole drift semi-finished product；
(5) laser surface hardening: the circular hole drift semi-finished product using the CO2 laser instrument of 5KW to obtain step (4) carry out laser surface hardening.
In the further design of the present invention, the circular hole drift semi-finished product obtained in step (4) carried out Darkening process to the surface of circular hole drift semi-finished product before carrying out the process of step (5) laser surface hardening.
The present invention has a beneficial effect highlighted below:
The circular hole drift processing technique of the present invention selects Cr12MoV steel to be raw material, and after entering the normative heat treatment such as quenching, tempering, the CO2 laser instrument that have employed 5KW carries out laser surface hardening to circular hole drift.The CO2 laser instrument of 5KW quickly scans drift with high energy laser beam, allow the very thin crust of punch head surface quickly absorbs energy and temperature steeply rises, self-quench hardening is carried out in moment, realize punch head surface hardening, and inside circular hole drift, still keep higher toughness, improve the service life of circular hole drift.
